Afrikaans (, ) is a West Germanic language that evolved in the Dutch Cape Colony from the Dutch vernacular of Holland proper (i.e. the Hollandic dialect) used by Dutch, French, and German settlers and people enslaved by them. Afrikaans gradually began to develop distinguishing characteristics during the course of the 18th century. Now spoken in South Africa, Namibia and (to a lesser extent) Botswana, Zambia and Zimbabwe, estimates of the total number of Afrikaans speakers range between 15 and 23 million. Most linguists consider Afrikaans to be a partly creole language. An estimated 90% to 95% of the vocabulary is of Dutch origin, with adopted words from other languages, including German and the Khoisan languages of Southern Africa. Differences with Dutch include a more analytic-type morphology and grammar, and some pronunciations. There is a large degree of mutual intelligibility between the two languages, especially in written form. About 13.5% of the South African population (7 million people) speak Afrikaans as a first language, making it the third most common natively-spoken language in the country, after Zulu and Xhosa. It has the widest geographic and racial distribution of the 11 official languages and is widely spoken and understood as a second or third language, although Zulu and English are estimated to be understood as a second language by a much larger proportion of the population. It is the majority language of the western half of South Africa—the provinces of the Northern Cape and Western Cape—and the first language of 75.8% of Coloured South Africans (4.8 million people), 60.8% of Whites (2.7 million people), 1.5% of Blacks (600,000 people), and 4.6% of Indians (58,000 people). Etymology The name of the language comes directly from the Dutch word (now spelled ) meaning "African". It was previously referred to as "Cape Dutch" (Kaap-Hollands/Kaap-Nederlands), a term also used to refer to the early Cape settlers collectively, or the derogatory "kitchen Dutch" (kombuistaal) from its use by slaves of colonial settlers "in the kitchen". History Origin The Afrikaans language arose in the Dutch Cape Colony, through a gradual divergence from European Dutch dialects, during the course of the 18th century. As early as the mid-18th century and as recently as the mid-20th century, Afrikaans was known in standard Dutch as a "kitchen language" (), lacking the prestige accorded, for example, even by the educational system in Africa, to languages spoken outside Africa. Other early epithets setting apart ("Cape Dutch", i.e. Afrikaans) as putatively beneath official Dutch standards included , and ("mutilated/broken/uncivilised Dutch"), as well as ("incorrect Dutch"). Den Besten theorises that modern Standard Afrikaans derives from two sources: Cape Dutch, a direct transplantation of European Dutch to Southern Africa, and 'Hottentot Dutch', a pidgin that descended from 'Foreigner Talk' and ultimately from the Dutch pidgin spoken by slaves, via a hypothetical Dutch creole. Thus in his view Afrikaans is neither a creole nor a direct descendant of Dutch, but a fusion of two transmission pathways. Development Most of the first settlers whose descendants today are the Afrikaners were from the United Provinces (now Netherlands), with up to one-sixth of the community of French Huguenot origin, and a seventh from Germany. African and Asian workers, Cape Coloured children of European settlers and Khoikhoi women, and slaves contributed to the development of Afrikaans. The slave population was made up of people from East Africa, West Africa, India, Madagascar, and the Dutch East Indies (modern Indonesia). A number were also indigenous Khoisan people, who were valued as interpreters, domestic servants, and labourers. Many free and enslaved women married or cohabited with the male Dutch settlers. M. F. Valkhoff argued that 75% of children born to female slaves in the Dutch Cape Colony between 1652 and 1672 had a Dutch father. Sarah Grey Thomason and Terrence Kaufman argue that Afrikaans' development as a separate language was "heavily conditioned by nonwhites who learned Dutch imperfectly as a second language." Beginning in about 1815, Afrikaans started to replace Malay as the language of instruction in Muslim schools in South Africa, written with the Arabic alphabet: see Arabic Afrikaans. Later, Afrikaans, now written with the Latin script, started to appear in newspapers and political and religious works in around 1850 (alongside the already established Dutch). In 1875, a group of Afrikaans-speakers from the Cape formed the ("Society for Real Afrikaners"), and published a number of books in Afrikaans including grammars, dictionaries, religious materials and histories. Until the early 20th century, Afrikaans was considered a Dutch dialect, alongside Standard Dutch, which it eventually replaced as an official language. Before the Boer wars, "and indeed for some time afterwards, Afrikaans was regarded as inappropriate for educated discourse. Rather, Afrikaans was described derogatorily as 'a kitchen language' or 'a bastard jargon', suitable for communication mainly between the Boers and their servants." Recognition In 1925, Afrikaans was recognised by the South African government as a distinct language, rather than simply a vernacular of Dutch. On 8 May 1925, twenty-three years after the Second Boer War ended, the Official Languages of the Union Act of 1925 was passed—mostly due to the efforts of the Afrikaans-language movement—at a joint sitting of the House of Assembly and the Senate, in which the Afrikaans language was declared a variety of Dutch. The Constitution of 1961 reversed the position of Afrikaans and Dutch, so that English and Afrikaans were the official languages, and Afrikaans was deemed to include Dutch. The Constitution of 1983 removed any mention of Dutch altogether. The Afrikaans Language Monument is located on a hill overlooking Paarl in the Western Cape Province. Officially opened on 10 October 1975, it was erected on the 100th anniversary of the founding of the Society of Real Afrikaners, and the 50th anniversary of Afrikaans being declared an official language of South Africa in distinction to Dutch. Standardisation The earliest Afrikaans texts were some doggerel verse from 1795 and a dialogue transcribed by a Dutch traveller in 1825. Afrikaans used the Latin alphabet around this time, although the Cape Muslim community used the Arabic script. In 1861, L.H. Meurant published his ("Conversation between Nicholas Truthsayer and John Doubter"), which is considered to be the first book published in Afrikaans. The first grammar book was published in 1876; a bilingual dictionary was later published in 1902. The main modern Afrikaans dictionary in use is the (HAT). A new authoritative dictionary, called (WAT), was under development as of 2018. The official orthography of Afrikaans is the , compiled by . The Afrikaans Bible The Afrikaners primarily were Protestants, of the Dutch Reformed Church of the 17th century. Their religious practices would later be influenced in South Africa by British ministries during the 1800s. A landmark in the development of the language was the translation of the whole Bible into Afrikaans. While significant advances had been made in the textual criticism of the Bible, especially the Greek New Testament, the 1933 translation followed the Textus Receptus and was closely akin to the . Before this, most Cape Dutch-Afrikaans speakers had to rely on the Dutch . This had its origins with the Synod of Dordrecht of 1618 and was thus in an archaic form of Dutch. This was hard for Dutch speakers to understand, and increasingly unintelligible for Afrikaans speakers. C. P. Hoogehout, , and Stephanus Jacobus du Toit were the first Afrikaans Bible translators. Important landmarks in the translation of the Scriptures were in 1878 with C. P. Hoogehout's translation of the (Gospel of Mark, lit. Gospel according to Mark); however, this translation was never published. The manuscript is to be found in the South African National Library, Cape Town. The first official translation of the entire Bible into Afrikaans was in 1933 by J. D. du Toit, E. E. van Rooyen, J. D. Kestell, H. C. M. Fourie, and BB Keet. This monumental work established Afrikaans as , that is "a pure and proper language" for religious purposes, especially amongst the deeply Calvinist Afrikaans religious community that previously had been sceptical of a Bible translation that varied from the Dutch version that they were used to. In 1983, a fresh translation marked the 50th anniversary of the 1933 version and provided a much-needed revision. The final editing of this edition was done by E. P. Groenewald, A. H. van Zyl, P. A. Verhoef, J. L. Helberg and W. Kempen. This translation was influenced by Eugene Nida's theory of dynamic equivalence which focused on finding the nearest equivalent in the receptor language to the idea that the Greek, Hebrew or Aramaic wanted to convey. A new translation, Die Bybel: 'n Direkte Vertaling was released in November 2020. It is the first truly ecumenical translation of the Bible in Afrikaans as translators from various churches, including the Roman Catholic and Anglican Churches, were involved. Various commercial translations of the Bible in Afrikaans have also appeared since the 1990s, such as Die Boodskap and the Nuwe Lewende Vertaling. Most of these translations were published by Christelike Uitgewersmaatskappy (CUM). Classification Indo-European languages Germanic West Germanic Low Franconian Dutch Afrikaans Afrikaans descended from Dutch dialects in the 17th century. It belongs to a West Germanic sub-group, the Low Franconian languages. Other West Germanic languages related to Afrikaans are German, English, the Frisian languages, and the unstandardised languages Low German and Yiddish. Geographic distribution Statistics Sociolinguistics Some state that instead of Afrikaners, which refers to an ethnic group, the terms or (lit. Afrikaans speakers) should be used for people of any ethnic origin who speak Afrikaans. Linguistic identity has not yet established which terms shall prevail, and all three are used in common parlance. Afrikaans is also widely spoken in Namibia. Before independence, Afrikaans had equal status with German as an official language. Since independence in 1990, Afrikaans has had constitutional recognition as a national, but not official, language. There is a much smaller number of Afrikaans speakers among Zimbabwe's white minority, as most have left the country since 1980. Afrikaans was also a medium of instruction for schools in Bophuthatswana, an Apartheid-era Bantustan. Eldoret in Kenya was founded by Afrikaners. Many South Africans living and working in Belgium, the Netherlands, the United Kingdom, Republic of Ireland, Australia, New Zealand, Canada, the United States, Israel, the UAE and Kuwait are also Afrikaans speakers. They have access to Afrikaans websites, news sites such as Netwerk24.com and Sake24, and radio broadcasts over the web, such as those from Radio Sonder Grense, Bokradio and Radio Pretoria. There are also many artists that tour to bring Afrikaans to the emigrants. Afrikaans has been influential in the development of South African English. Many Afrikaans loanwords have found their way into South African English, such as ("pickup truck"), ("barbecue"), ("tangerine"), (American "sneakers", British "trainers", Canadian "runners"). A few words in standard English are derived from Afrikaans, such as aardvark (lit. "earth pig"), trek ("pioneering journey", in Afrikaans lit. "pull" but used also for "migrate"), spoor ("animal track"), ("Southern African grassland" in Afrikaans, lit. "field"), commando from Afrikaans meaning small fighting unit, ("tree snake") and ("segregation"; more accurately "apartness" or "the state or condition of being apart"). In 1976, secondary-school pupils in Soweto began a rebellion in response to the government's decision that Afrikaans be used as the language of instruction for half the subjects taught in non-White schools (with English continuing for the other half). Although English is the mother tongue of only 8.2% of the population, it is the language most widely understood, and the second language of a majority of South Africans. Afrikaans is more widely spoken than English in the Northern and Western Cape provinces, several hundred kilometres from Soweto. The Black community's opposition to Afrikaans and preference for continuing English instruction was underlined when the government rescinded the policy one month after the uprising: 96% of Black schools chose English (over Afrikaans or native languages) as the language of instruction. Afrikaans-medium schools were also accused of using language policy to deter black African parents. Some of these parents, in part supported by provincial departments of education, initiated litigation which enabled enrolment with English as language of instruction. By 2006 there were 300 single-medium Afrikaans schools, compared to 2,500 in 1994, after most converted to dual-medium education. Due to Afrikaans being viewed as the "language of the white oppressor" by some, pressure has been increased to remove Afrikaans as a teaching language in South African universities, resulting in bloody student protests in 2015. Under South Africa's Constitution of 1996, Afrikaans remains an official language, and has equal status to English and nine other languages. The new policy means that the use of Afrikaans is now often reduced in favour of English, or to accommodate the other official languages. In 1996, for example, the South African Broadcasting Corporation reduced the amount of television airtime in Afrikaans, while South African Airways dropped its Afrikaans name from its livery. Similarly, South Africa's diplomatic missions overseas now display the name of the country only in English and their host country's language, and not in Afrikaans. Meanwhile, the constitution of the Western Cape, which went into effect in 1998, declares Afrikaans to be an official language of the province alongside English and Xhosa. In spite of these moves, the language has remained strong, and Afrikaans newspapers and magazines continue to have large circulation figures. Indeed, the Afrikaans-language general-interest family magazine has the largest readership of any magazine in the country. In addition, a pay-TV channel in Afrikaans called KykNet was launched in 1999, and an Afrikaans music channel, MK () (lit. 'Music Channel'), in 2005. A large number of Afrikaans books are still published every year, mainly by the publishers Human & Rousseau, , , and . The Afrikaans film trilogy (first released in 2008) caused a reawakening of the Afrikaans film industry (which had been moribund since the mid to late 1990s ) and Belgian-born singer Karen Zoid's debut single "" (released 2001) caused a resurgence in the Afrikaans music industry, as well as giving rise to the Afrikaans Rock genre. Afrikaans has two monuments erected in its honour. The first was erected in , South Africa, in 1893, and the second, nowadays better-known Afrikaans Language Monument (), was built in Paarl, South Africa, in 1975. When the British design magazine Wallpaper described Afrikaans as "one of the world's ugliest languages" in its September 2005 article about the monument, South African billionaire Johann Rupert (chairman of the Richemont Group), responded by withdrawing advertising for brands such as Cartier, Van Cleef & Arpels, Montblanc and Alfred Dunhill from the magazine. The author of the article, Bronwyn Davies, was an English-speaking South African. Mutual intelligibility with Dutch An estimated 90 to 95% of the Afrikaans lexicon is ultimately of Dutch origin, and there are few lexical differences between the two languages. Afrikaans has a considerably more regular morphology, grammar, and spelling. There is a high degree of mutual intelligibility between the two languages, particularly in written form. Afrikaans acquired some lexical and syntactical borrowings from other languages such as Malay, Khoisan languages, Portuguese, and Bantu languages, and Afrikaans has also been significantly influenced by South African English. Dutch speakers are confronted with fewer non-cognates when listening to Afrikaans than the other way round. Mutual intelligibility thus tends to be asymmetrical, as it is easier for Dutch speakers to understand Afrikaans than for Afrikaans speakers to understand Dutch. In general, mutual intelligibility between Dutch and Afrikaans is far better than between Dutch and Frisian or between Danish and Swedish. The South African poet writer Breyten Breytenbach, attempting to visualise the language distance for Anglophones once remarked that the differences between (Standard) Dutch and Afrikaans are comparable to those between the Received Pronunciation and Southern American English. Current status Post-apartheid South Africa has seen a loss of preferential treatment by the government for Afrikaans, in terms of education, social events, media (TV and radio), and general status throughout the country, given that it now shares its place as official language with ten other languages. Nevertheless, Afrikaans remains more prevalent in the media – radio, newspapers and television – than any of the other official languages, except English. More than 300 book titles in Afrikaans are published annually. South African census figures suggest a growing number of speakers in all nine provinces, a total of 6.85 million in 2011 compared to 5.98 million a decade earlier. The South African Institute of Race Relations (SAIRR) projects that a growing majority will be Coloured Afrikaans speakers. Afrikaans speakers experience higher employment rates than other South African language groups, though as of 2012 half a million were unemployed. Despite the challenges of demotion and emigration that it faces in South Africa, the Afrikaans vernacular remains competitive, being popular in DSTV pay channels and several internet sites, while generating high newspaper and music CD sales. A resurgence in Afrikaans popular music since the late 1990s has invigorated the language, especially among a younger generation of South Africans. A recent trend is the increased availability of pre-school educational CDs and DVDs. Such media also prove popular with the extensive Afrikaans-speaking emigrant communities who seek to retain language proficiency in a household context. Afrikaans-language cinema showed signs of new vigour in the early 21st century. The 2007 film , the first full-length Afrikaans movie since Paljas in 1998, is seen as the dawn of a new era in Afrikaans cinema. Several short films have been created and more feature-length movies, such as and (both in 2008) have been produced, besides the 2011 Afrikaans-language film , which was the first Afrikaans film to screen at the Cannes Film Festival. The film was also released in 2011. The Afrikaans film industry started gaining international recognition via the likes of big Afrikaans Hollywood film stars, like Charlize Theron (Monster) and Sharlto Copley (District 9) promoting their mother tongue. SABC3 announced early in 2009 that it would increase Afrikaans programming due to the "growing Afrikaans-language market and [their] need for working capital as Afrikaans advertising is the only advertising that sells in the current South African television market". In April 2009, SABC3 started screening several Afrikaans-language programmes. Further latent support for the language derives from its de-politicised image in the eyes of younger-generation South Africans, who less and less often view it as "the language of the oppressor". Indeed, there is a groundswell movement within Afrikaans to be inclusive, and to promote itself along with the other indigenous official languages. In Namibia, the percentage of Afrikaans speakers declined from 11.4% (2001 Census) to 10.4% (2011 Census). The major concentrations are in Hardap (41.0%), ǁKaras (36.1%), Erongo (20.5%), Khomas (18.5%), Omaheke (10.0%), Otjozondjupa (9.4%), Kunene (4.2%), and Oshikoto (2.3%). Many native speakers of Bantu languages and English also speak Afrikaans as a second language. It is widely taught in South African schools, with about 10.3 million second-language students. Even in KwaZulu-Natal (where there are relatively few Afrikaans home-speakers), the majority of pupils opt for Afrikaans as their first additional language because it is regarded as easier than Zulu. Afrikaans is offered at many universities outside South Africa, including in the Netherlands, Belgium, Germany, Poland, Russia and the United States. Grammar In Afrikaans grammar, there is no distinction between the infinitive and present forms of verbs, with the exception of the verbs 'to be' and 'to have': In addition, verbs do not conjugate differently depending on the subject. For example, Only a handful of Afrikaans verbs have a preterite, namely the auxiliary ("to be"), the modal verbs, and the verb ("to think"). The preterite of ("may") is rare in contemporary Afrikaans. All other verbs use the perfect tense, het + past participle (ge-), for the past. Therefore, there is no distinction in Afrikaans between I drank and I have drunk. (In colloquial German, the past tense is also often replaced with the perfect.) When telling a longer story, Afrikaans speakers usually avoid the perfect and simply use the present tense, or historical present tense instead (as is possible, but less common, in English as well). A particular feature of Afrikaans is its use of the double negative; it is classified in Afrikaans as and is something that is absent from the other West Germanic standard languages. For example, English: He can not speak Afrikaans. / He can't speak Afrikaans. Both French and San origins have been suggested for double negation in Afrikaans. While double negation is still found in Low Franconian dialects in West Flanders and in some "isolated" villages in the centre of the Netherlands (such as Garderen), it takes a different form, which is not found in Afrikaans. The following is an example: * (lit. I want not this do not.) English: I do not want to do this. * Compare with , which changes the meaning to "I want not to do this." Whereas emphasizes a lack of desire to act, emphasizes the act itself. The was the Middle Dutch way to negate but it has been suggested that since became highly non-voiced, or was needed to complement the . With time the disappeared in most Dutch dialects. The double negative construction has been fully grammaticalised in standard Afrikaans and its proper use follows a set of fairly complex rules as the examples below show: A notable exception to this is the use of the negating grammar form that coincides with negating the English present participle. In this case there is only a single negation. English: He is in [the] hospital, though he eats not. Certain words in Afrikaans arise due to grammar. For example, , which literally means "must not", usually becomes ; although one does not have to write or say it like this, virtually all Afrikaans speakers will change the two words to in the same way as do not shifts to don't in English. The Dutch word ("it" in English) does not correspond to in Afrikaans. The Dutch words corresponding to Afrikaans are , , and . Phonology Vowels As phonemes, and occur only in the words 'mirror' and 'bullet', which used to be pronounced with sequences and , respectively. In other cases, and occur as allophones of, respectively, and before . is phonetically long before . is always stressed and occurs only in the word 'wedges'. The closest unrounded counterparts of are central , rather than front . occur only in a few words. occurs as an allophone of before , though this occurs primarily dialectally, most commonly in the former Transvaal and Free State provinces. Diphthongs occur mainly in loanwords. Consonants All obstruents at the ends of words are devoiced, so that e.g. a final is realized as . occur only in loanwords. is also an allophone of in some environments. is most often uvular . Velar occurs only in some speakers. is usually an alveolar trill or tap . In some parts of the former Cape Province, it is realized uvularly, either as a trill or a fricative . Dialects Following early dialectal studies of Afrikaans, it was theorised that three main historical dialects probably existed after the Great Trek in the 1830s. These dialects are the Northern Cape, Western Cape, and Eastern Cape dialects. Northern Cape dialect may have resulted from contact between Dutch settlers and the Khoekhoe people between the Great Karoo and the Kunene, and Eastern Cape dialect between the Dutch and the Xhosa. Remnants of these dialects still remain in present-day Afrikaans, although the standardising effect of Standard Afrikaans has contributed to a great levelling of differences in modern times. There is also a prison cant, known as Sabela, which is based on Afrikaans, yet heavily influenced by Zulu. This language is used as a secret language in prison and is taught to initiates. The term Kaapse Afrikaans () is sometimes erroneously used to refer to the entire Western Cape dialect; it is more commonly used for a particular sociolect spoken in the Cape Peninsula of South Africa. was once spoken by all population groups. However, it became increasingly restricted to the Cape Coloured ethnic group in Cape Town and surrounds. Kaapse Afrikaans is still understood by the large majority of native Afrikaans speakers in South Africa. preserves some features more similar to Dutch than to Afrikaans. The first-person singular pronoun as in Dutch as opposed to Afrikaans . The diminutive endings , pronounced as in Dutch and not as as in Afrikaans. The use of the form (compare Dutch ) as opposed to Afrikaans . has some other features not typically found in Afrikaans. The pronunciation of , normally as in Dutch is often a . This is the strongest feature of . The insertion of after , and when followed by , e.g. as opposed to Standard Afrikaans . is also characterised by much code-switching between South African English and Afrikaans, especially in the inner-city and areas in Cape Town with lower socio-economic status. An example of characteristic : : English (literal): And I say to you, what seek you here by me? I seek you not! No, go now away! English: And I'm telling you, what are you looking for here? I'm not looking for you! No, go away now! The term ("Afrikaans of the Orange River") is sometimes erroneously used to refer to the Northern Cape dialect; it is more commonly used for the regional peculiarities of standard Afrikaans spoken in the Upington/Orange River wine district of South Africa. Some of the characteristics of are the plural form (Ma-, ), variant pronunciation such as in ("Church") and ("money") and the ending , which indicates possession. Patagonian Afrikaans dialect A distinct dialect of Afrikaans is spoken by the 650-strong South African community of Argentina, in the region of Patagonia. Influences on Afrikaans from other languages Malay Due to the early settlement of a Cape Malay community in Cape Town, who are now known as Coloureds, numerous Classical Malay words were brought into Afrikaans. Some of these words entered Dutch via people arriving from what is now known as Indonesia as part of their colonial heritage. Malay words in Afrikaans include: , which means 'very'/'much'/'many' (from ) is a very commonly used Afrikaans word, different from its Dutch equivalent or . , Afrikaans for jacket (from , ultimately from Persian), used where Dutch would use or . The word in Dutch is now considered archaic and only used in written, literary texts. bobotie, a traditional Cape-Malay dish, made from spiced minced meat baked with an egg-based topping. , which means banana. This is different from the common Dutch word . The Indonesian word is also used in Dutch, though usage is more common. , which means saucer (from , also from Persian). Portuguese Some words originally came from Portuguese such as ("umbrella") from the Portuguese , ("pen/cattle enclosure") from the Portuguese and ("corn", from ). Some of these words also exist in Dutch, like "parasol", though usage is less common and meanings can slightly differ. Khoisan languages , meaning cannabis , meaning lizard, diminutive adapted from a Khoekhoe word , meaning insect, from the Khoisan xo-xo , blanket of animal hides , walking stick from Khoekhoe Some of these words also exist in Dutch, though with a more specific meaning: for example means "South-African tribal javelin" and means "South-African tribal blanket of animal hides". Bantu languages Loanwords from Bantu languages in Afrikaans include the names of indigenous birds, such as and , and indigenous plants, such as and . , from the Zulu word meaning "scholar" or "student", but used to mean someone who is a student of/expert on a certain subject, i.e. He is a language . , meaning bride price, from (and referring to) lobolo of the Nguni languages , the grey crowned crane, known in Latin as Balearica regulorum , medium-sized dioecious tree known in Latin as Sclerocarya birrea , species of thatching grass known as Hyparrhenia , deciduous tree also known by its Latin name, Spirostachys africana / , an adaption of the word , meaning "to go home" or "to knock off (from work)". French The revoking of the Edict of Nantes on 22 October 1685 was a milestone in the history of South Africa, for it marked the beginning of the great Huguenot exodus from France. It is estimated that between 250,000 and 300,000 Protestants left France between 1685 and 1700; out of these, according to Louvois, 100,000 had received military training. A measure of the calibre of these immigrants and of their acceptance by host countries (in particular South Africa) is given by H. V. Morton in his book: In Search of South Africa (London, 1948). The Huguenots were responsible for a great linguistic contribution to Afrikaans, particularly in terms of military terminology as many of them fought on the battlefields during the wars of the Great Trek. Most of the words in this list are descendants from Dutch borrowings from French, Old French or Latin, and are not direct influences from French on Afrikaans. Orthography The Afrikaans writing system is based on Dutch, using the 26 letters of the ISO basic Latin alphabet, plus 16 additional vowels with diacritics. The hyphen (e.g. in a compound like see-eend 'sea duck'), apostrophe (e.g. ma's 'mothers'), and a whitespace character (e.g. in multi-word units like Dooie See 'Dead Sea') is part of the orthography of words, while the indefinite article ʼn is a ligature. All the alphabet letters, including those with diacritics, have capital letters as allographs; the ʼn does not have a capital letter allograph. This means that Afrikaans has 88 graphemes with allographs in total. In Afrikaans, many consonants are dropped from the earlier Dutch spelling. For example, ('only') in Dutch becomes in Afrikaans. Also, Afrikaans and some Dutch dialects make no distinction between and , having merged the latter into the former; while the word for "south" is written in Dutch, it is spelled in Afrikaans (as well as dialectal Dutch writings) to represent this merger. Similarly, the Dutch digraph , normally pronounced as , corresponds to Afrikaans , except where it replaces the Dutch suffix which is pronounced as , as in > . Another difference is the indefinite article, in Afrikaans and in Dutch. "A book" is in Afrikaans, whereas it is either or in Dutch. This is usually pronounced as just a weak vowel, , just like English "a". The diminutive suffix in Afrikaans is , or , whereas in Dutch it is or , hence a "bit" is ʼn in Afrikaans and in Dutch. The letters c, q, x, and z occur almost exclusively in borrowings from French, English, Greek and Latin. This is usually because words that had c and ch in the original Dutch are spelled with k and g, respectively, in Afrikaans. Similarly original qu and x are most often spelt kw and ks, respectively. For example, instead of equatoriaal, and instead of excuus. The vowels with diacritics in non-loanword Afrikaans are: á, ä, é, è, ê, ë, í, î, ï, ó, ô, ö, ú, û, ü, ý. Diacritics are ignored when alphabetising, though they are still important, even when typing the diacritic forms may be difficult. For example, ("ate") instead of the 3 e's alongside each other: *, which can never occur in Afrikaans, or , which translates to "say", whereas is a possessive form. The acute's (á, é, í, ó, ú, ý) primary function is to place emphasis on a word (i.e. for emphatic reasons), by adding it to the emphasised syllable of the word. For example, sál ("will" (verb)), néé ('no'), móét ("must"), hý ("he"), gewéét ("knew"). The acute is only placed on the i if it is the only vowel in the emphasised word: wil ('want' (verb)) becomes wíl, but lui ('lazy') becomes lúi. Only a few non-loan words is spelled with acutes, e.g. dié ('this'), ná ('after'), óf ... óf ('either ... or'), nóg ... nóg ('neither ... nor'), etc. Only four non-loan words are spelled with the grave: ('yes?', 'right?', 'eh?'), ('here, take this!' or '[this is] yours!'), hè ('huh?', 'what?', 'eh?'), and appèl ('(formal) appeal' (noun)). Initial apostrophes A few short words in Afrikaans take initial apostrophes. In modern Afrikaans, these words are always written in lower case (except if the entire line is uppercase), and if they occur at the beginning of a sentence, the next word is capitalised. Three examples of such apostrophed words are . The last (the indefinite article) is the only apostrophed word that is common in modern written Afrikaans, since the other examples are shortened versions of other words ( and , respectively) and are rarely found outside of a poetic context. Here are a few examples: The apostrophe and the following letter are regarded as two separate characters, and are never written using a single glyph, although a single character variant of the indefinite article appears in Unicode, . Table of characters For more on the pronunciation of the letters below, see Help:IPA/Afrikaans. Afrikaans phrases Although there are many different dialects and accents, the transcription would be fairly standard. In the Dutch language the word means African, in the general sense. Consequently, Afrikaans is commonly denoted as . This ambiguity also exists in Afrikaans itself and is resolved either in the context of its usage, or by using in the adjective sense (e.g. Afrika-olifant for African elephant). A handful of Afrikaans words are exactly the same as in English. The following Afrikaans sentences, for example, are exactly the same in the two languages, in terms of both their meaning and spelling; only their pronunciation differs.

Lord's Prayer (Afrikaans New Living translation) Ons Vader in die hemel, laat U Naam geheilig word. Laat U koningsheerskappy spoedig kom. Laat U wil hier op aarde uitgevoer word soos in die hemel. Gee ons die porsie brood wat ons vir vandag nodig het. En vergeef ons ons sondeskuld soos ons ook óns skuldenaars vergewe het. Bewaar ons sodat ons nie aan verleiding sal toegee nie; en bevry ons van die greep van die bose. Want van U is die koninkryk, en die krag, en die heerlikheid, tot in ewigheid. Amen Lord's Prayer (Original translation): Onse Vader wat in die hemel is, laat U Naam geheilig word; laat U koninkryk kom; laat U wil geskied op die aarde, net soos in die hemel. Gee ons vandag ons daaglikse brood; en vergeef ons ons skulde soos ons ons skuldenaars vergewe en laat ons nie in die versoeking nie maar verlos ons van die bose Want aan U behoort die koninkryk en die krag en die heerlikheid tot in ewigheid.

Arsenal Football Club is an English professional football club based in Holloway, North London. Arsenal compete in the Premier League, the top flight of English football. The club has won 13 league titles (including one unbeaten title), a record 14 FA Cups, two League Cups, 17 FA Community Shields, the Football League Centenary Trophy, one European Cup Winners' Cup and one Inter-Cities Fairs Cup. In terms of trophies won, it is the third-most successful club in English football. Arsenal was the first club from the South of England to join the Football League in 1893, and they reached the First Division in 1904. Relegated only once, in 1913, they continue the longest streak in the top division, and have won the second-most top-flight matches in English football history. In the 1930s, Arsenal won five League Championships and two FA Cups, and another FA Cup and two Championships after the war. In 1970–71, they won their first League and FA Cup Double. Between 1989 and 2005, they won five League titles and five FA Cups, including two more Doubles. They completed the 20th century with the highest average league position. Between 1998 and 2017, Arsenal qualified for the UEFA Champions League for nineteen consecutive seasons. In 1886, munitions workers at the Royal Arsenal in Woolwich founded the club as Dial Square. In 1913 the club crossed the city to Arsenal Stadium in Highbury, becoming close neighbours of Tottenham Hotspur, and creating the North London derby. Herbert Chapman, who changed the fortunes of Arsenal forever, won the club its first silverware, and his legacy led the club to dominate the 1930s. He helped introduce the WM formation, floodlights, and shirt numbers; he also added the white sleeves and brighter red to the club's jersey. Arsène Wenger is the club's longest-serving manager and has won the most trophies for it. He won a record seven FA Cups, and his title-winning team set an English record for the longest top-flight unbeaten league run at 49 games between 2003 and 2004, receiving the nickname The Invincibles. In 2006, the club moved to the nearby Emirates Stadium. With an annual revenue of £367.1m in the 2021–22 season, Arsenal was estimated to be worth US$2.26 billion by Forbes, making it the world's tenth most valuable football club, while it is one of the most followed on social media. The motto of the club is Victoria Concordia Crescit, Latin for "Victory Through Harmony". History 1886–1912: from Dial Square to Arsenal In October 1886, Scotsman David Danskin and fifteen fellow munitions workers in Woolwich formed Dial Square Football Club, named after a workshop at the heart of the Royal Arsenal complex. Each member contributed sixpence and Danskin also added three shillings to help form the club. Dial Square played their first match on 11 December 1886 against Eastern Wanderers and won 6–0. The club had renamed to Royal Arsenal by January 1887, and its first home was Plumstead Common, though they spent most of their time playing at the Manor Ground. Their first trophies were the Kent Senior Cup and London Charity Cup in 1889–90 and the London Senior Cup in 1890–91; these were the only county association trophies Arsenal won during their time in South East London. In 1891, Royal Arsenal became the first London club to turn professional. Royal Arsenal renamed for a second time upon becoming a limited liability company in 1893. They registered their new name, Woolwich Arsenal, with The Football League when the club ascended later that year. Woolwich Arsenal was the first southern member of The Football League, starting out in the Second Division and reaching the First Division in 1904. Falling attendances, due to financial difficulties among the munitions workers and the arrival of more accessible football clubs elsewhere in the city, led the club close to bankruptcy by 1910. Businessmen Henry Norris and William Hall became involved in the club, and sought to move them elsewhere. 1912–1925: Bank of England club In 1913, soon after relegation back to the Second Division, the club moved across the river to the new Arsenal Stadium in Highbury. In 1919, The Football League controversially voted to promote The Arsenal, instead of relegated local rivals Tottenham Hotspur, into the newly enlarged First Division, despite only finishing fifth in the Second Division's last pre-war season of 1914–15. Later that year, The Arsenal started dropping "The" in official documents, gradually shifting its name for the final time towards Arsenal, as it is generally known today. With a new home and First Division football, attendances were more than double those at the Manor Ground, and Arsenal's budget grew rapidly. With record-breaking spending and gate receipts, Arsenal quickly became known as the Bank of England club. 1925–1934: Herbert Chapman's legendary Gunners Arsenal's location and record-breaking salary offer lured star Huddersfield Town manager Herbert Chapman in 1925. Over the next five years, Chapman built a revolutionary new Arsenal. He appointed an enduring new trainer Tom Whittaker who would one day rise to become a fabled Arsenal manager himself, and with the help of player Charlie Buchan, implemented a twist on the nascent WM formation. He also captured generational young talents such as Cliff Bastin and Eddie Hapgood, and lavished Highbury's income on stars like David Jack and Alex James. Transformed, Chapman's Arsenal claimed their first national trophy, the FA Cup in 1930, and League Championships followed in 1930–31 and 1932–33. Chapman also presided over off the pitch changes: white sleeves and shirt numbers were added to the kit; a Tube station was named after the club; and the first of two opulent, Art Deco stands was completed, with some of the first floodlights in English football. Suddenly, in the middle of the 1933–34 season, Chapman died of pneumonia. 1934–1947: Shaw, Allison & World War II Chapman's death meant work was left to his colleagues Joe Shaw and George Allison, with both proving to be shrewd & consummate custodians of Chapman's excellent Arsenal team, seeing out a hat-trick of league wins with the 1933–34, 1934–35, and 1937–38 titles, and then furthermore winning the 1936 FA Cup. World War II meant The Football League was suspended for seven years. While Arsenal were paraded by the nation as a symbol of solidarity with war efforts, the war took a huge toll on the team as the club had had more players killed than any top flight club. Furthermore, debt from reconstructing an ambitious North Bank Stand redevelopment greatly bled Arsenal's resources. 1947–1962: Tom Whittaker's meteoric Gunners Despite this period of turbulence & churn, Arsenal returned to win the league in the second post-war season of 1947–48. This was Tom Whittaker's first season as manager, and meant the club equalled the champions of England record. Tom Whittaker, despite his disarming humble & modest disposition, was oft-referred to as the "brains" behind the charismatic Chapman's legendary Arsenal side. He gathered a successful & highly skilled Arsenal side in spite of greatly limited resources, with a fiery and expansive style that drove great fanfare at the time. They won a third FA Cup in 1950, and then won a record-breaking seventh championship in 1952–53 making Arsenal the most successful team in English history at the time. 1962–1984: Billy Wright, Bertie Mee and Neill's cohorts Arsenal were not to win the League or the FA Cup for another 18 years. The '53 Champions squad had aged, and the club failed to attract strong enough replacements. Although Arsenal were competitive during these years, their fortunes had waned; the club spent most of the 1950s and 1960s in mid-table mediocrity. Even former England captain Billy Wright could not bring the club any success as manager, in a stint between 1962 and 1966. Arsenal tentatively appointed club physiotherapist Bertie Mee as acting manager in 1966. With new assistant Don Howe and new players such as Bob McNab and George Graham, Mee led Arsenal to their first League Cup finals, in 1967–68 and 1968–69. Next season saw a breakthrough, with Arsenal's first competitive European trophy, the 1969–70 Inter-Cities Fairs Cup. The season after, Arsenal achieved an even greater triumph with their first League and FA Cup double, and a new champions of England record. This marked a premature high point of the decade; the Double-winning side was soon broken up and the rest of the decade was characterised by a series of near misses, with Arsenal finishing as FA Cup runners up in 1972, and First Division runners-up in 1972–73. Former player Terry Neill succeeded Mee in 1976. At the age of 34, he became the youngest Arsenal manager to date. With new signings like Malcolm Macdonald and Pat Jennings, and a crop of talent in the side like Liam Brady and Frank Stapleton, the club reached a trio of FA Cup finals (1978 FA Cup, 1979 FA Cup and 1980 FA Cup), and lost the 1980 European Cup Winners' Cup Final on penalties. The club's only trophy during this time was the 1979 FA Cup, achieved with a last-minute 3–2 victory over Manchester United, in a final is widely regarded as a classic. 1984–1996: George Graham's Arsenal One of Mee's double winners, George Graham, returned as manager in 1986, with Arsenal winning their first League Cup in 1987, Graham's first season in charge. New signings Nigel Winterburn, Lee Dixon and Steve Bould had joined the club by 1988 to complete the "famous Back Four", led by homegrown player Tony Adams. Graham's credo of prioritising defensive excellence seemingly clashed with the club's traditional expansive motif & the young player demographic at the club at the time, however they quickly gained a cult following after initial successes. They immediately won the 1988 Football League Centenary Trophy, and followed it with the 1988–89 Football League title, snatched with a last-minute goal in the final game of the season against fellow title challengers Liverpool. Graham's Arsenal won another title in 1990–91, losing only one match, won the FA Cup and League Cup double in 1993, and the European Cup Winners' Cup in 1994. Graham's reputation was tarnished when he was found to have taken kickbacks from agent Rune Hauge for signing certain players, and he was dismissed in 1995. His replacement, Bruce Rioch, lasted for only one season, leaving the club after a dispute with the board of directors. 1996–2018: Wenger years The club metamorphosed during the tenure of French manager Arsène Wenger, who was appointed in 1996. Attacking football, an overhaul of dietary and fitness practices, and efficiency with money have defined his reign. Accumulating key players from Wenger's homeland, such as Patrick Vieira and Thierry Henry, Arsenal won a second League and Cup double in 1997–98 and a third in 2001–02. In addition, the club reached the final of the 1999–2000 UEFA Cup, were victorious in the 2003 and 2005 FA Cup finals, and won the Premier League in 2003–04 without losing a single match, an achievement which earned the side the nickname "The Invincibles". This feat came within a run of 49 league matches unbeaten from 7 May 2003 to 24 October 2004, a national record. Arsenal finished in either first or second place in the league in eight of Wenger's first nine seasons at the club, although they never won the title in two consecutive seasons. The club had never progressed beyond the quarter-finals of the Champions League until 2005–06; in that season they became the first club from London to reach the final in the competition's fifty-year history, but were beaten 2–1 by Barcelona. In July 2006, they moved into the Emirates Stadium, after 93 years at Highbury. Arsenal reached the final of the 2007 and 2011 League Cups, losing 2–1 to Chelsea and Birmingham City respectively. The club had not gained a trophy since the 2005 FA Cup until, spearheaded by club record acquisition Mesut Özil, Arsenal beat Hull City in the 2014 FA Cup Final, coming back from a 2–0 deficit to win the match 3–2. A year later, Arsenal completed another victorious FA Cup campaign, and became the most successful club in the tournament's history by winning their 13th FA Cup in 2016–17. However, in that same season, Arsenal finished fifth in the league, the first time they had finished outside the top four since before Wenger arrived in 1996. After another unspectacular league season the following year, Wenger departed Arsenal on 13 May 2018. 2018–2020: post-Wenger revolution After conducting an overhaul in the club's operating model to coincide with Wenger's departure, Spaniard Unai Emery was named as the club's new head coach on 23 May 2018. He became the club's first ever 'head coach' and second manager from outside the United Kingdom. In Emery's first season, Arsenal finished fifth in the Premier League and as runner-up in the Europa League. On 29 November 2019, Emery was dismissed as manager and former player and assistant first team coach Freddie Ljungberg was appointed as interim head coach. 2020–: Arteta era On 20 December 2019, Arsenal appointed former club captain Mikel Arteta as the new head coach. Arsenal finished the league season in eighth, their lowest finish since 1994–95, but beat Chelsea 2–1 to earn a record-extending 14th FA Cup win. After the season, Arteta's title was changed from head coach to manager. On 18 April 2021, Arsenal were announced as a founding club of the breakaway European competition The Super League; they withdrew from the competition two days later amid near-universal condemnation. Arsenal finished the season in eighth place once again, not qualifying for a European competition for the first time in 26 years. In the 2022–23 Premier League season, Arsenal returned to the Champions League by coming second to Manchester City. Arsenal led the league for most of the season, but suffered a series of losses at the end of the run, setting a record for most time spent on top of the table without actually winning the league. Crest Unveiled in 1888, Royal Arsenal's first crest featured three cannons viewed from above, pointing northwards, similar to the coat of arms of the Metropolitan Borough of Woolwich (nowadays transferred to the coat of arms of the Royal Borough of Greenwich). These can sometimes be mistaken for chimneys, but the presence of a carved lion's head and a cascabel on each are clear indicators that they are cannons. This was dropped after the move to Highbury in 1913, only to be reinstated in 1922, when the club adopted a crest featuring a single cannon, pointing eastwards, with the club's nickname, The Gunners, inscribed alongside it; this crest only lasted until 1925, when the cannon was reversed to point westward and its barrel slimmed down. In 1949, the club unveiled a modernised crest featuring the same style of cannon below the club's name, set in blackletter typography, and above the coat of arms of the Metropolitan Borough of Islington and a scroll inscribed with the club's newly adopted Latin motto, Victoria Concordia Crescit – "victory comes from harmony" – coined by the club's programme editor Harry Homer. For the first time, the crest was rendered in colour, which varied slightly over the crest's lifespan, finally becoming red, gold and green. Because of the numerous revisions of the crest, Arsenal were unable to copyright it. Although the club had managed to register the crest as a trademark, and had fought (and eventually won) a long legal battle with a local street trader who sold "unofficial" Arsenal merchandise, Arsenal eventually sought a more comprehensive legal protection. Therefore, in 2002 they introduced a new crest featuring more modern curved lines and a simplified style, which was copyrightable. The cannon once again faces east and the club's name is written in a sans-serif typeface above the cannon. Green was replaced by dark blue. The new crest was criticised by some supporters; the Arsenal Independent Supporters' Association claimed that the club had ignored much of Arsenal's history and tradition with such a radical modern design, and that fans had not been properly consulted on the issue. Until the 1960s, a badge was worn on the playing shirt only for high-profile matches such as FA Cup finals, usually in the form of a monogram of the club's initials in red on a white background. The monogram theme was developed into an Art Deco-style badge on which the letters A and C framed a football rather than the letter F, the whole set within a hexagonal border. This early example of a corporate logo, introduced as part of Herbert Chapman's rebranding of the club in the 1930s, was used not only on Cup Final shirts but as a design feature throughout Highbury Stadium, including above the main entrance and inlaid in the floors. From 1967, a white cannon was regularly worn on the shirts, until replaced by the club crest, sometimes with the addition of the nickname "The Gunners", in the 1990s. In the 2011–12 season, Arsenal celebrated their 125th anniversary. The celebrations included a modified version of the current crest worn on their jerseys for the season. The crest was all white, surrounded by 15 oak leaves to the right and 15 laurel leaves to the left. The oak leaves represent the 15 founding members of the club who met at the Royal Oak pub. The 15 laurel leaves represent the design detail on the six pence pieces paid by the founding fathers to establish the club. The laurel leaves also represent strength. To complete the crest, 1886 and 2011 are shown on either sides of the motto "Forward" at the bottom of the crest. Colours For much of Arsenal's history, their home colours have been bright red shirts with white sleeves and white shorts, though this has not always been the case. The choice of red is in recognition of a charitable donation from Nottingham Forest, soon after Arsenal's foundation in 1886. Two of Dial Square's founding members, Fred Beardsley and Morris Bates, were former Forest players who had moved to Woolwich for work. As they put together the first team in the area, no kit could be found, so Beardsley and Bates wrote home for help and received a set of kit and a ball. The shirt was redcurrant, a dark shade of red, and was worn with white shorts and socks with blue and white hoops. In 1933, Herbert Chapman, wanting his players to be more distinctly dressed, updated the kit, adding white sleeves and changing the shade to a brighter pillar box red. Two possibilities have been suggested for the origin of the white sleeves. One story reports that Chapman noticed a supporter in the stands wearing a red sleeveless sweater over a white shirt; another was that he was inspired by a similar outfit worn by the cartoonist Tom Webster, with whom Chapman played golf. Regardless of which story is true, the red and white shirts have come to define Arsenal and the team have worn the combination ever since, aside from two seasons. The first was 1966–67, when Arsenal wore all-red shirts; this proved unpopular and the white sleeves returned the following season. The second was 2005–06, the last season that Arsenal played at Highbury, when the team wore commemorative redcurrant shirts similar to those worn in 1913, their first season in the stadium; the club reverted to their normal colours at the start of the next season. In the 2008–09 season, Arsenal replaced the traditional all-white sleeves with red sleeves with a broad white stripe. Arsenal's home colours have been the inspiration for at least three other clubs. In 1909, Sparta Prague adopted a dark red kit like the one Arsenal wore at the time; in 1938, Hibernian adopted the design of the Arsenal shirt sleeves in their own green and white strip. In 1941, Luis Robledo, an England-schooled founder of Santa Fe and a fan of Arsenal, selected the main colors for his newly created team. In 1920, Sporting Clube de Braga's manager returned from a game at Highbury and changed his team's green kit to a duplicate of Arsenal's red with white sleeves and shorts, giving rise to the team's nickname of Os Arsenalistas. These teams still wear those designs to this day. For many years Arsenal's away colours were white or navy blue. However, in 1968 the FA banned navy shirts (they looked too similar to referees' black kit) so in the 1969–70 season, Arsenal introduced an away kit of yellow shirts with blue shorts. This kit was worn in the 1971 FA Cup Final as Arsenal beat Liverpool to secure the double for the first time in their history. The yellow and blue strip became almost as famous as their iconic red and white home kit. Arsenal reached the FA Cup final again the following year wearing the red and white home strip and were beaten by Leeds United. Arsenal then competed in three consecutive FA Cup finals between 1978 and 1980 wearing their "lucky" yellow and blue strip, which remained the club's away strip until the release of a green and navy away kit in 1982–83. The following season, Arsenal returned to the yellow and blue scheme, albeit with a darker shade of blue than before. When Nike took over from Adidas as Arsenal's kit provider in 1994, Arsenal's away colours were again changed to two-tone blue shirts and shorts. Since the advent of the lucrative replica kit market, the away kits have been changed regularly, with Arsenal usually releasing both away and third choice kits. During this period the designs have been either all blue designs, or variations on the traditional yellow and blue, such as the metallic gold and navy strip used in the 2001–02 season, the yellow and dark grey used from 2005 to 2007, and the yellow and maroon of 2010 to 2013. Until 2014, the away kit was changed every season, and the outgoing away kit became the third-choice kit if a new home kit was being introduced in the same year. Since Puma began manufacturing Arsenal's kits in 2014, new home, away and third kits were released every single season. In the 2017–18 season, Puma released a new color scheme for the away and third kits. The away kit was a light blue, which fades to a darker blue near the bottom, while the third kit was black with red highlight. Puma returned to the original color scheme for the 2018–19 season. From the 2019–20 season Arsenal's kits are manufactured by Adidas. In the 2020–21 season, Adidas unveiled the new away kit to mark the 15-year anniversary since leaving Highbury. The new away kit is white, with a marbled pattern all across to replicate the iconic marble hall in the East stand of Highbury. Kit suppliers and shirt sponsors Stadiums Before joining the Football League, Arsenal played briefly on Plumstead Common, then at the Manor Ground in Plumstead, then spent three years between 1890 and 1893 at the nearby Invicta Ground. Upon joining the Football League in 1893, the club returned to the Manor Ground and installed stands and terracing, upgrading it from just a field. Arsenal continued to play their home games there for the next twenty years (with two exceptions in the 1894–95 season), until the move to north London in 1913. Widely referred to as Highbury, Arsenal Stadium was the club's home from September 1913 until May 2006. The original stadium was designed by the renowned football architect Archibald Leitch, and had a design common to many football grounds in the UK at the time, with a single covered stand and three open-air banks of terracing. The entire stadium was given a massive overhaul in the 1930s: new Art Deco West and East stands were constructed, opening in 1932 and 1936 respectively, and a roof was added to the North Bank terrace, which was bombed during the Second World War and not restored until 1954. Highbury could hold more than 60,000 spectators at its peak, and had a capacity of 57,000 until the early 1990s. The Taylor Report and Premier League regulations obliged Arsenal to convert Highbury to an all-seater stadium in time for the 1993–94 season, thus reducing the capacity to 38,419 seated spectators. This capacity had to be reduced further during Champions League matches to accommodate additional advertising boards, so much so that for two seasons, from 1998 to 2000, Arsenal played Champions League home matches at Wembley, which could house more than 70,000 spectators. Expansion of Highbury was restricted because the East Stand had been designated as a Grade II listed building and the other three stands were close to residential properties. These limitations prevented the club from maximising matchday revenue during the 1990s and first decade of the 21st century, putting them in danger of being left behind in the football boom of that time. After considering various options, in 2000 Arsenal proposed building a new 60,361-capacity stadium at Ashburton Grove, since named the Emirates Stadium, about 500 metres south-west of Highbury. The project was initially delayed by red tape and rising costs, and construction was completed in July 2006, in time for the start of the 2006–07 season. The stadium was named after its sponsors, the airline company Emirates, with whom the club signed the largest sponsorship deal in English football history, worth around £100 million. Some fans referred to the ground as Ashburton Grove, or the Grove, as they did not agree with corporate sponsorship of stadium names. The stadium will be officially known as Emirates Stadium until at least 2028, and the airline will be the club's shirt sponsor until at least 2024. From the start of the 2010–11 season on, the stands of the stadium have been officially known as North Bank, East Stand, West Stand and Clock end. The capacity of the Emirates now stands at 60,704. Arsenal's players train at the Shenley Training Centre in Hertfordshire, a purpose-built facility which opened in 1999. Before that the club used facilities on a nearby site owned by the University College of London Students' Union. Until 1961 they had trained at Highbury. Arsenal's Academy under-18 teams play their home matches at Shenley, while the reserves play their games at Meadow Park, which is also the home of Boreham Wood F.C. Both the Academy under-18 & the reserves occasionally play their big games at the Emirates in front of a crowd reduced to only the lower west stand. Supporters and rivalries Arsenal's fanbase are referred to as "Gooners" – the name derived from the club's nickname "The Gunners". Virtually all home matches sell out; in 2007–08 Arsenal had the second-highest average League attendance for an English club (60,070, which was 99.5% of available capacity), and, as of 2015, the third-highest all-time average attendance. Arsenal have the seventh highest average attendance of European football clubs only behind Borussia Dortmund, FC Barcelona, Manchester United, Real Madrid, Bayern Munich, and Schalke. The club's location, adjoining wealthy areas such as Canonbury and Barnsbury, mixed areas such as Islington, Holloway, Highbury, and the adjacent London Borough of Camden, and largely working-class areas such as Finsbury Park and Stoke Newington, has meant that Arsenal's supporters have come from a variety of social classes. Much of the Afro-Caribbean support comes from the neighbouring London Borough of Hackney and a large portion of the South Asian Arsenal supporters commute to the stadium from Wembley Park, North West of the capital. There was also traditionally a large Irish community that followed Arsenal, with the surrounding Islington and particularly the nearby Archway area having a large community of residents with Irish heritage. But Irish migration to North London is recently much lower than in the 1960s or 1970s. Like all major English football clubs, Arsenal have a number of domestic supporters' clubs, including the Arsenal Football Supporters' Club, which works closely with the club, and the Arsenal Independent Supporters' Association, which maintains a more independent line. The Arsenal Supporters' Trust promotes greater participation in ownership of the club by fans. The club's supporters also publish fanzines such as The Gooner, Gunflash and the satirical Up The Arse! There have always been Arsenal supporters outside London, and since the advent of satellite television, a supporter's attachment to a football club has become less dependent on geography. Consequently, Arsenal have a significant number of fans from beyond London and all over the world; in 2007, 24 UK, 37 Irish and 49 other overseas supporters clubs were affiliated with the club. A 2011 report by SPORT+MARKT estimated Arsenal's global fanbase at 113 million. The club's social media activity was the fifth highest in world football during the 2014–15 season. Anthem The team's anthem is The Angel (North London Forever) by Louis Dunford. The song is typically played at Arsenal home games before a match. Other Songs In addition to the usual English football chants, Arsenal's supporters sing "One-Nil to the Arsenal" (to the tune of "Go West") and also regularly sing "Who's that team they call the Arsenal", "Good Old Arsenal" (to the tune of "Rule, Britannia!") and "We're the North Bank/Clock End Highbury". The fans also chant "Boring, Boring Arsenal" in self-deprecating reference to Arsenal's reputation during the 1970s and 1980s as an overly defensive, cautious team. Rivalries Arsenal's longest-running and deepest rivalry is with their nearest major neighbour, Tottenham Hotspur; matches between the two are referred to as the North London derby. There also exists a rivalry between Arsenal and Chelsea. In addition, Arsenal and Manchester United developed a strong on-pitch rivalry in the late 1980s, which intensified in the early 2000s when both clubs were competing for the Premier League title. During the 2010s and now the 2020s, a competitive rivalry with Manchester City began during the Arteta era following a close title race in the 2022-23 Premier League season. Mascot The club mascot is Gunnersaurus Rex, a smiling, 7-foot-tall green dinosaur, who first appeared at a home match against Manchester City in August 1994 (or 1993). He is based on a drawing by then 11-year-old Peter Lovell, whose design and another similar idea won a Junior Gunners contest; his official back story is that he hatched from an egg found during renovations at Highbury. The same person, Jerry Quy, has been inside the suit from the start; in early October 2020, as part of cost-cutting brought about by the COVID-19 pandemic, the club made him redundant from that and his other part-time job in supporter liaison, together with 55 full-time employees, although they later said Gunnersaurus could return after spectators were allowed back in stadiums. An online fundraiser was begun for Quy, and Mesut Özil offered to pay his salary himself as long as he remains with Arsenal. In November 2020, in advance of COVID-19 regulations being relaxed to allow supporters to attend home games from 3 December, Arsenal announced that Gunnersaurus would return, to be played by a roster of people that could include Quy if he wished. Ownership and finances The largest shareholder on the Arsenal board is American sports tycoon Stan Kroenke. Kroenke first launched a bid for the club in April 2007, and faced competition for shares from Red and White Securities, which acquired its first shares from David Dein in August 2007. Red & White Securities was co-owned by Russian billionaire Alisher Usmanov and Iranian London-based financier Farhad Moshiri, though Usmanov bought Moshiri's stake in 2016. Kroenke came close to the 30% takeover threshold in November 2009, when he increased his holding to 18,594 shares (29.9%). In April 2011, Kroenke achieved a full takeover by purchasing the shareholdings of Nina Bracewell-Smith and Danny Fiszman, taking his shareholding to 62.89%. In May 2017, Kroenke owned 41,721 shares (67.05%) and Red & White Securities owned 18,695 shares (30.04%). In January 2018, Kroenke expanded his ownership by buying twenty-two more shares, taking his total ownership to 67.09%. In August 2018, Kroenke bought out Usmanov for £550m. Now owning more than 90% of the shares, he had the required stake to complete the buyout of the remaining shares and become the sole owner. There has been criticism of Arsenal's poor performance since Kroenke took over, which has been attributed to his ownership. Ivan Gazidis was the club's Chief executive from 2009 to 2018. Arsenal's parent company, Arsenal Holdings plc, operates as an unlisted public limited company, whose ownership is considerably different from that of other football clubs. Only 62,219 shares in Arsenal have been issued, and they are not traded on a public exchange such as the FTSE or AIM; instead, they are traded relatively infrequently on the ICAP Securities and Derivatives Exchange, a specialist market. On 29 May 2017, a single share in Arsenal had a mid price of £18,000, which sets the club's market capitalisation value at approximately £1,119.9m. Most football clubs are not listed on an exchange, which makes direct comparisons of their values difficult. Consultants Brand Finance valued the club's brand and intangible assets at $703m in 2015, and consider Arsenal an AAA global brand. Business magazine Forbes valued Arsenal as a whole at $2.238 billion (£1.69 billion) in 2018, ranked third in English football. Research by the Henley Business School ranked Arsenal second in English football, modelling the club's value at £1.118 billion in 2015. Arsenal's financial results for the 2019–20 season showed an after tax loss of £47.8m, due in part to the impact of the COVID-19 pandemic. The Deloitte Football Money League is a publication that homogenises and compares clubs' annual revenue. Deloitte put Arsenal's footballing revenue in 2019 at £392.7m (€445.6m), ranking Arsenal eleventh among world football clubs. Arsenal and Deloitte both listed the match day revenue generated in 2019 by the Emirates Stadium as €109.2m (£96.2m). In popular culture Partly due to their proximity to the Alexandra Palace transmitter, Arsenal have appeared in a number of media "firsts". On 22 January 1927, their match at Highbury against Sheffield United was the first English League match to be broadcast live on radio. A decade later, on 16 September 1937, an exhibition match between Arsenal's first team and the reserves was the first football match in the world to be televised live. Arsenal also featured in the first edition of the BBC's Match of the Day, which screened highlights of their match against Liverpool at Anfield on 22 August 1964. Sky's coverage of Arsenal's January 2010 match against Manchester United was the first live public broadcast of a sports event on 3D television. As one of the most successful teams in the country, Arsenal have often featured when football is depicted in the arts in Britain. They formed the backdrop to one of the earliest football-related novels, The Arsenal Stadium Mystery (1939), which was made into a film in the same year. The story centres on a friendly match between Arsenal and an amateur side, one of whose players is poisoned while playing. Many Arsenal players appeared as themselves in the film and manager George Allison was given a speaking part. The book Fever Pitch by Nick Hornby was an autobiographical account of Hornby's life and relationship with football and Arsenal in particular. Published in 1992, it formed part of the revival and rehabilitation of football in British society during the 1990s. The book was twice adapted for the cinema – the 1997 British film focuses on Arsenal's 1988–89 title win, and a 2005 American version features a fan of baseball's Boston Red Sox. Arsenal have often been stereotyped as a defensive and "boring" side, especially during the 1970s and 1980s. In the 1997 film The Full Monty the principal characters move forward in a line and raise their hands, deliberately mimicking the Arsenal defence's offside trap, in an attempt to co-ordinate their striptease routine. Fifteen years later an almost identical scene was included in the 2012 Disney science-fiction film John Carter (director and co-writer Andrew Stanton, a notable overseas supporter of the club), along with other visual cues and oblique dialogue hints and references to the club throughout the film. Another film reference to the club's defence comes in the film Plunkett & Macleane, in which two characters are named Dixon and Winterburn after Arsenal's long-serving full backs – the right-sided Lee Dixon and the left-sided Nigel Winterburn. In August 2022, Amazon Prime Video released an eight-episode docuseries called All or Nothing: Arsenal. It documented the club by spending time with the coaching staff and players behind the scenes both on and off the field throughout their 2021–22 season, in which they were the youngest team in the Premier League with an average starting age of 24 years and 308 days – more than a whole year younger than the next team. In the community In 1985, Arsenal founded a community scheme, "Arsenal in the Community", which offered sporting, social inclusion, educational and charitable projects. The club support a number of charitable causes directly and in 1992 established The Arsenal Charitable Trust, which by 2006 had raised more than £2 million for local causes. An ex-professional and celebrity football team associated with the club also raised money by playing charity matches. The club launched the Arsenal for Everyone initiative in 2008 as an annual celebration of the diversity of the Arsenal family. In the 2009–10 season Arsenal announced that they had raised a record breaking £818,897 for the Great Ormond Street Hospital Children's Charity. The original target was £500,000. In 2022, Arsenal and Adidas partnered up to launch the "No More Red" campaign to support the long-standing work being done by Arsenal in the Community to help keep young people safe from knife crime and youth violence. To promote the event, the club launched an exclusive all white kit that was not commercially available and only awarded to individuals who are making a positive difference in the community. Save the Children has been Arsenal global charity partner since 2011 and have worked together in numerous projects to improve safety and well-being for vulnerable children in London and abroad. On 3 September 2016 The Arsenal Foundation has donated £1m to build football pitches for children in London, Indonesia, Iraq, Jordan and Somalia thanks to The Arsenal Foundation Legends Match against Milan Glorie at the Emirates Stadium. On 3 June 2018, Arsenal played Real Madrid in the Corazon Classic Match 2018 at the Bernabeu, where the proceeds went to Realtoo Real Madrid Foundation projects that are aimed at the most vulnerable children. In addition there will be a return meeting on 8 September 2018 at the Emirates stadium where proceeds will go towards the Arsenal foundation. During 2007 in Pleiku, Vietnam, Arsenal partnered with the JMG Academy and the Hoang Anh Gia Lai Corporation to found a youth academy for the V.League 1 side Hoàng Anh Lai Lai, which saw a selection of Vietnam based players train with Arsenal; the club ended their partnership with the club in 2017. Additionally, the club formally partnered with a variety of clubs overseas including Virginia based Richmond Strikers and Cairo based Wadi Degla.

As of June 2020, they are one of seven teams, the others being Manchester United, Blackburn Rovers, Chelsea, Manchester City, Leicester City and Liverpool, to have won the Premier League since its formation in 1992. They hold the highest number of FA Cup trophies, with 14. The club is one of only six clubs to have won the FA Cup twice in succession, in 2002 and 2003, and 2014 and 2015. Arsenal have achieved three League and FA Cup "Doubles" (in 1971, 1998 and 2002), a feat only previously achieved by Manchester United (in 1994, 1996 and 1999). They were the first side in English football to complete the FA Cup and League Cup double, in 1993. Arsenal were also the first London club to reach the final of the UEFA Champions League, in 2006, losing the final 2–1 to Barcelona. Arsenal have one of the best top-flight records in history, having finished below fourteenth only seven times. They have won the second most top flight league matches in English football, and have also accumulated the second most points, whether calculated by two points per win or by the contemporary points value. They have been in the top flight for the most consecutive seasons (98 as of 2023–24). Arsenal also have the highest average league finishing position for the 20th century, with an average league placement of 8.5. Arsenal hold the record for the longest run of unbeaten League matches (49 between May 2003 and October 2004). This included all 38 matches of their title-winning 2003–04 season, when Arsenal became only the second club to finish a top-flight campaign unbeaten, after Preston North End (who played only 22 matches) in 1888–89. They also hold the record for the longest top flight win streak. Arsenal set a Champions League record during the 2005–06 season by going ten matches without conceding a goal, beating the previous best of seven set by A.C. Milan. They went a record total stretch of 995 minutes without letting an opponent score; the streak ended in the final, when Samuel Eto'o scored a 76th-minute equaliser for Barcelona. David O'Leary holds the record for Arsenal appearances, having played 722 first-team matches between 1975 and 1993. Fellow centre half and former captain Tony Adams comes second, having played 669 times. The record for a goalkeeper is held by David Seaman, with 564 appearances. Thierry Henry is the club's top goalscorer with 228 goals in all competitions between 1999 and 2012, having surpassed Ian Wright's total of 185 in October 2005. Wright's record had stood since September 1997, when he overtook the longstanding total of 178 goals set by winger Cliff Bastin in 1939. Henry also holds the club record for goals scored in the League, with 175, a record that had been held by Bastin until February 2006. Declan Rice is the Arsenal record signing after a deal with West Ham United was completed in July 2023, for an initial £100 million. This easily surpassed the former record of £72 million for Nicolas Pepe. Arsenal's record home attendance is 73,707, for a UEFA Champions League match against RC Lens on 25 November 1998 at Wembley Stadium, where the club formerly played home European matches because of the limits on Highbury's capacity. The record attendance for an Arsenal match at Highbury is 73,295, for a 0–0 draw against Sunderland on 9 March 1935, while that at Emirates Stadium is 60,161, for a 2–2 draw with Manchester United on 3 November 2007. Honours Arsenal's first ever silverware was won as the Royal Arsenal in 1890. The Kent Junior Cup, won by Royal Arsenal's reserves, was the club's first trophy, while the first team's first trophy came three weeks later when they won the Kent Senior Cup. Their first national senior honour came in 1930, when they won the FA Cup. The club enjoyed further success in the 1930s, winning another FA Cup and five Football League First Division titles. Arsenal won their first league and cup double in the 1970–71 season and twice repeated the feat, in 1997–98 and 2001–02, as well as winning a cup double of the FA Cup and League Cup in 1992–93. Seasons in bold are seasons when the club won a Double of the league and FA Cup, or of the FA Cup and League Cup. The 2003–04 season was the only 38-match league season unbeaten in English football history. A special gold version of the Premier League trophy was commissioned and presented to the club the following season. As of 6 August 2023 – Record – Shared title County FAs When the FA Cup was the only national football association competition available to Arsenal, the other football association competitions were County Cups, and they made up many of the matches the club played during a season. Arsenal's first first-team trophy was a County Cup, the inaugural Kent Senior Cup. Arsenal became ineligible for the London Cups when the club turned professional in 1891, and rarely participated in County Cups after this. Due to the club's original location within the borders of both the London and Kent Football Associations, Arsenal competed in and won trophies organised by each. Other During Arsenal's history, the club has participated in and won a variety of pre-season and friendly honours. These include Arsenal's own pre-season competition the Emirates Cup, begun in 2007. During the wars, previous competitions were widely suspended and the club had to participate in wartime competitions. During WWII, Arsenal won several of these. Arsenal Women Arsenal Women is the women's football club affiliated to Arsenal. Founded as Arsenal Ladies F.C. in 1987 by Vic Akers, they turned semi-professional in 2002 and have been managed since 2021 by Jonas Eidevall; Akers holds the role of Honorary President of Arsenal Women. As part of the festivities surrounding their 30th anniversary in 2017, the club announced that they were changing their formal name to Arsenal Women F.C., and would use "Arsenal" in all references except rare cases where there might be confusion with the men's side. Arsenal Women are the most successful team in English women's football having won a total of 58 trophies. In the 2008–09 season, they won all three major English trophies – the FA Women's Premier League, FA Women's Cup and FA Women's Premier League Cup, and, as of 2017, were the only English side to have won the UEFA Women's Cup or UEFA Women's Champions League, having won the Cup in the 2006–07 season as part of a unique quadruple. The men's and women's clubs are formally separate entities but have close ties; Arsenal Women are entitled to play at the Emirates Stadium, though they usually play their home matches at Meadow Park in Borehamwood.

American cuisine consists of the cooking style and traditional dishes prepared in the United States of America. It has been significantly influenced by Europeans, indigenous Native Americans, Africans, Latin Americans, Asians, Pacific Islanders, and many other cultures and traditions. Principal influences on American cuisine are European, Native American, soul food, regional heritages including Cajun, Louisiana Creole, Pennsylvania Dutch, Mormon foodways, Texan, Tex-Mex, New Mexican, and Tlingit, and the cuisines of immigrant groups such as Chinese American, Italian American, Greek American and Mexican American. The large size of America and its long history of immigration have created an especially diverse cuisine that varies by region. American cooking dates back to the traditions of the Native Americans, whose diet included a mix of farmed and hunted food, and varied widely across the continent. The Colonial period created a mix of Native and Old World cookery, and brought with it new crops and livestock. During the early 19th century, cooking was based mostly on what the agrarian population could grow, hunt, or raise on their land. With an increasing influx of immigrants, and a move to city life, American food further diversified in the later part of the 19th century. The 20th century saw a revolution in cooking as new technologies, the World Wars, a scientific understanding of food, and continued immigration combined to create a wide range of new foods. This has allowed for the current rich diversity in food dishes throughout the country. This was driven in part by the many chefs and television personalities who contributed to the rise of the culinary arts in America. Highlights of American cuisine include milkshakes, barbecue, and a wide range of fried foods. Many quintessential American dishes are unique takes on food originally from other culinary traditions, including pizza, hot dogs, and Tex-Mex. Regional highlights include a range of fish dishes in the coastal states, gumbo, and cheesesteak. American cuisine has specific foods that are eaten on holidays, such as a turkey at thanksgiving dinner or Christmas dinner. Modern American cuisine includes a focus on fast food, as well as take-out food, which is often ethnic. There is also a vibrant culinary scene in the country surrounding televised celebrity chefs. History Native Americans origins: American cuisine before 1600 Early Native Americans utilized a number of cooking methods in early American cuisine that have been blended with the methods of early Europeans to form the basis of what is now American cuisine. Nearly all regions and subregions of the present-day cuisine have roots in the foodways of Native Americans, who lived in tribes numbering in the thousands. Prior to 1600, native peoples lived off the land in very diverse bioregions and had done so for thousands of years, often living a nomadic life where their diet changed with the season. Many practiced a form of agriculture revolving around the Three Sisters, the rotation of beans, maize, and squash as staples of their diet. In the East, this was documented as early as the 1620s in Of Plimoth Plantation, evidenced by the pages William Bradford wrote regarding Squanto, who showed them the traditional regional method of burying a fish or eel in a mound with seeds for maize to improve the soil; this itself is also part of the widely practiced phenomenon of companion planting. Wild game was equally a staple of nearly every tribe: generally, deer, elk, and bison were staples, as were rabbits and hare. The Cherokee of the Southern Appalachians used blowguns made of an indigenous type of bamboo to hunt squirrels. Northern tribes like the Ojibwe of what is now the state of Michigan and the peoples of the Wabanaki of what is now the state of Maine would stalk and hunt moose, whereas their Southern counterparts, like the Choctaw or Catawba, hunted snapping turtles and other testudines, possums, and young alligators in the subtropical swamps of Louisiana and South Carolina. Many tribes would preserve their meat in the form of pemmican, needed on long journeys or to survive harsh winters. Fish and crustaceans As with the hunted game, the biome in which one lived often dictated what was available to catch. For example, the Apache and Navajo peoples of the Southwest, whose territories each would have included swathes of New Mexico and Arizona, generally do not eat fish because in both cultures it is taboo, as well as often inconvenient. The Navajo believe that fish have a part in the story of creation, the Apache were in general afraid of water since they associated it with thunder, and the arid desert climate made fish a rarity. However, in the culture of the Lenape, the tribe that originally lived in New Jersey, on the Delaware River, and the area that now comprises New York City, fish and shellfish were a staple in their diet and it was such a revered part of the culture that there is a documented and still-practiced harvest dance called the Fish Dance. Originally it would have been done to celebrate bringing in fish from places like the Delaware or Raritan River or the estuary around Manhattan Island and the completion of smoking them as a source of food for the winter ahead. Eastern tribes would have eaten cod, particularly groups that spoke the Algonquian languages of New England as far south as present day Connecticut, winter flounder and other flatfish, species of herring like the alewife, shad, Atlantic herring, and Atlantic menhaden, They also would have consumed the Atlantic sturgeon and drum. In the West, Pacific several species of sturgeon, like the white sturgeon and green sturgeon, olachen and several autochthonal fish of the Oncorhynchus family including the rainbow trout, cutthroat trout, coho salmon, kokanee salmon, and chinook salmon. The last makes an appearance in the accounts of Lewis and Clark as being fished for in the Columbia River Basin, and this species is named for a family of tribes of the Pacific Northwest, indicating its important role in that food culture. Pacific gray whales and humpbacks were hunted by American Indians off the Northwest coast, especially by the Makah, and used for their meat and oil. Catfish was also popular among native people throughout the land, over many types of terrain. Crustaceans included shrimp, lobster, crayfish, and dungeness crabs in the Northwest and shrimp, lobster and blue crabs in the East. Other shellfish include abalone and geoduck on the West Coast, while on the East Coast the surf clam, quahog, and the soft-shell clam. Oysters were eaten on both shores, as were mussels and periwinkles. Cooking methods Early American natives used a number of cooking methods that have been blended with early European cooking methods to form the basis of American cuisine. Grilling meats was common. Spit roasting over a pit fire was common as well. Vegetables, especially root vegetables, were often cooked directly in the ashes of the fire. As early Native Americans lacked pottery that could be used directly over a fire, they developed a technique many anthropologists call "stone boiling". They heated rocks in a fire, then added the rocks to a pot filled with water until it came to a boil to cook the meat or vegetables. In what is now the Southwestern United States, they also created adobe ovens, dubbed hornos by the Spanish, to bake products such as cornmeal bread. Other parts of America dug pit ovens, which were also used to steam foods by adding heated rocks or embers. One technique performed extensively by New England tribes was adding seaweed or corn husks on top of the layers of stones to steam fish and shellfish as well as vegetables. A later addition was potatoes, a garden plant that came to New England by the 18th century, added while still in skin with corn in husk, later to be referred to as a clambake by colonists. Colonial period The European settlement of the Americas introduced a number of ingredients, spices, herbs, and cooking styles to the continent. When European colonists came to Virginia, Pennsylvania, Massachusetts, and any of the other English colonies on the eastern seaboard of North America, their initial attempts at survival included planting crops familiar to them from back home in England. In the same way, they farmed animals for clothing and meat. Through hardships and the eventual establishment of trade with England, the West Indies and other regions, the colonists were able to derive a cuisine similar to what they had previously consumed in Britain and Ireland, while also introducing local animals and plants to their diet. American colonists followed along the line of British cookery up until the Revolution, when a desire to distinguish themselves from Britain led Americans to create "American" styles of cookery. In 1796, the first American cookbook was published, and others followed. There was a general disdain for French cuisine/French cookery, even with French Huguenot settlers in South Carolina and French-Canadian emigrants in America. One of the cookbooks that proliferated in the colonies was The Art of Cookery Made Plain and Easy (1747) by Hannah Glasse, who referred to "the blind folly of this age that would rather be imposed on by a French booby, than give encouragement to a good English cook!" Of the French recipes given in the text, she speaks out flagrantly against the dishes as she "... think[s] it an odd jumble of trash." With the introduction of slavery, Africans were brought into the colonies. With them, came foods and ingredients such as bananas, peanuts, sweet potato, yams, and coffee, and cooking styles reminiscent of West African cuisines are still found in many dishes, especially in Southern cuisine. The expulsion of the Acadians from Acadia led many of them to Louisiana, where they left a French influence in the diet of those settled in Louisiana, and among the Acadian Francophones who settled eastern Maine and parts of what is now northern Vermont at the same time they colonized New Brunswick. Some of the Jews who fled from the Inquisition with other Sephardic Jews in the 15th century had previously settled in Recife, Brazil and the West Indies, where their cuisine was influenced by new local ingredients like molasses, rum, sugar, vanilla, chocolate, peppers, corn, tomatoes, kidney beans, string beans and turkey. In 1654, twenty three Sephardic Jews arrived in New Amsterdam bringing this cuisine with them to the early colonial United States. Early American Jewish cuisine was heavily influenced by this branch of Sephardic cuisine. Many of the recipes were bound up in observance of traditional holidays and remained true to their origins. These included dishes such as stew and fish fried in olive oil, beef and bean stews, almond puddings, and egg custards. The first kosher cookbook in America was the Jewish Cookery Book by Esther Levy, published in 1871 in Philadelphia and includes many of the traditional recipes. Common ingredients The American colonial diet varied depending on the settled region in which someone lived. Local cuisine patterns had been established by the mid-18th century. The New England colonies were extremely similar in their dietary habits to those that many of them had brought from England. As many of the New Englanders were originally from England, game hunting was useful when they immigrated to the New World. Many of the northern colonists depended upon their ability to hunt, or upon others from whom they could purchase game. Hunting was the preferred method of protein acquisition, as opposed to animal husbandry, which required much more work to defend the kept animals against raids A striking difference for the colonists in New England compared to other regions was seasonality. While in the southern colonies, they could farm almost year-round, in the northern colonies, the growing seasons were very restricted. In addition, northern colonists' close proximity to the ocean gave them a bounty of fresh fish to add to their diet. Wheat, the grain used to bake bread back in England, was almost impossible to grow, and imports of wheat were far from cost productive. Substitutes in cases such as this included cornmeal. The Johnnycake was a poor substitute to some for wheaten bread, but acceptance by both the northern and southern colonies seems evident. Livestock and game Commonly hunted game included deer, bear, buffalo, and wild turkey. The larger muscles of the animals were roasted and served with currant sauce, while the other smaller portions went into soups, stews, sausages, pies, and pastries. In addition to the game, colonists' protein intake was supplemented by mutton. The Spanish in Florida originally introduced sheep to the New World, but this development never quite reached the North, and there they were introduced by the Dutch and English. The keeping of sheep was a result of the English non-practice of animal husbandry. The animals provided wool when young and mutton upon maturity after wool production was no longer desirable. The forage-based diet for sheep that prevailed in the Colonies produced a characteristically strong, gamy flavor and a tougher consistency, which required aging and slow cooking to tenderize. Fats and oils Fats and oils made from animals served to cook many colonial foods. Many homes had a sack made of deerskin filled with bear oil for cooking, while solidified bear fat resembled shortening. Rendered pork fat made the most popular cooking medium, especially from the cooking of bacon. Pork fat was used more often in the southern colonies than the northern colonies as the Spanish introduced pigs earlier to the South. The colonists enjoyed butter in cooking as well, but it was rare prior to the American Revolution, as cattle were not yet plentiful. Alcoholic drinks Prior to the Revolution, New Englanders consumed large quantities of rum and beer, as maritime trade provided them relatively easy access to the goods needed to produce these items. Rum was the distilled spirit of choice, as the main ingredient, molasses, was readily available from trade with the West Indies. Further into the interior, however, one would often find colonists consuming whiskey, as they did not have similar access to sugar cane. They did have ready access to corn and rye, which they used to produce their whiskey. Until the Revolution, many considered whiskey to be a coarse alcohol unfit for human consumption, as many believed that it caused the poor to become raucous and unkempt drunkards. In addition to these alcohol-based products produced in America, imports were seen on merchant shelves, including wine and brandy. Southern variations In comparison to the northern colonies, the southern colonies were quite diverse in their agricultural diet. The uplands of Piedmont and the coastal lowlands made up the two main parts of the southern colonies. The diet of the uplands often included wild game, cabbage, string beans, corn, squashes and white potatoes. People had biscuits as part of their breakfast, along with healthy portions of pork. The lowlands of Louisiana included a varied diet heavily influenced by the French, Spanish, Acadians, Germans, Native Americans, Africans and Caribbeans. Rice played a large part of the diet in Louisiana. In addition, unlike the uplands, the lowlands subsistence of protein came mostly from coastal seafood. Much of the diet involved the use of peppers, as it still does to this day. Post-colonial cuisine During the 18th and 19th centuries, Americans developed many new foods. Some, such as Rocky Mountain oysters, stayed regional; some spread throughout the nation but with little international appeal, such as peanut butter (a core ingredient of the peanut butter and jelly sandwich); and some spread throughout the world, such as popcorn, cola, fried chicken, cornbread, unleavened muffins such as the poppyseed muffin, and brownies. 19th-century American farmhouse During the 1800s, American farms were mostly self-sufficient, but certain staples like salt, coffee, sugar, and baking soda would be purchased at the town general store. If the family did not grow wheat, then flour would also be purchased. Another luxury was canned salmon, which was sometimes eaten for Sunday dinner. Items purchased at the general store would be paid for with eggs, butter or some other food from the farm. Women were responsible for much of the processing of food like straining fresh milk, churning butter, making molasses from sorghum, grinding corn into cornmeal or cleaning whole chickens. Fresh picked apples were pressed into cider, which could be fermented to make apple cider vinegar. Fruits and vegetables were preserved by various means like canning, drying or pickling. One contemporary writer from Michigan described October as cider season, when apple butter would be made. Her writings mention johnnycakes, and, as winter fare, buckwheat cakes. Typical farmhouse fare included fried chicken, simmered green beans, boiled corn, chicken and dumplings, fried ham, boiled beans and beets, stewed tomatoes, potatoes, and coleslaw made of shredded cabbage. Pon haus, similar to the scrapple of the Pennsylvania Dutch, was a typical breakfast dish among the Germans who had settled Indiana in the 19th century. Pork scraps and corn meal were cooked into a thick porridge and molded in loaf pans. Once solidified, the mixture would be cut and fried. During the fall months, pork might be replaced with fried apples or potatoes. It was served with buttered biscuits, jam, jelly, milk gravy or sorghum syrup. Fruit butter might be made from apples, plums or peaches to accompany the meal. 20th century The 20th century revolutionized American cooking, with the advent of many new technologies, and a continued influx of immigrants with unique food traditions. Pre-World War I At the universities, nutritionists and home economists taught a new scientific approach to food. In the early 1900s muckraking journalists raised public concern about the wholesomeness of industrialized food products that contained various preservatives and adulterants of unknown safety. From 1902 to 1912 Harvey Washington Wiley, a chemist at the U.S. Department of Agriculture, supervised "hygienic table trials" to test the safety of food additives and preservatives. His work contributed to the enactment of the Pure Food and Drug Act of 1906. He became the first commissioner of the FDA and later led the laboratories of Good Housekeeping Magazine. During World War I the Progressives' moral advice about food conservation was emphasized in large-scale state and federal programs designed to educate housewives. Large-scale foreign aid during and after the war brought American standards to Europe. From 1912 to the end of the 1930s researchers discovered and popularized the role of various vitamins and minerals in human health. Starting with iodized salt in 1924, commercially distributed food began to be fortified with vitamins and minerals. In 1932, milk began to be fortified with viosterol, a purified vitamin D2 product. Synthetic thiamin (vitamin B1) first became available after 1936 and bakers began voluntarily enriching bread with high-vitamin yeast or synthetic vitamins in the late 1930s. The cookware of the period was made of cast iron and these were thoroughly seasoned with pork fat. Fried salt pork with gravy was an indulgent fat-laden dish often served with a side of boiled potatoes. In the Appalachian region a dish called "killed lettuce" was made with pokeweed, dandelion and assorted wild greens that were drizzled with hot bacon grease until wilted or "killed". Pie could be served up to three times a day and many varieties were prepared depending on the season. During the spring months, pies would be made of rhubarb and strawberry; in summer peach, cherry, blackberry, blueberry, elderberry and grape; and in fall apple. The staples of the urban diet were bread, dairy and canned goods. Dinner might be tomato bisque from a can topped with cream or a salad made of canned string beans and mayonnaise. Many preferred to purchase food at delicatessens, rather than attempt to prepare meals in the cramped kitchenettes. German delicatessens in cities like New York and Milwaukee sold imported cold cuts, potato salads, schmierkase, wienerwurst, North Sea herring, assorted pickles (pickled cucumber) and other prepared foods. Jewish immigrants from Germany soon followed suit, replacing pork dishes with corned beef (salt-cured beef) and pastrami. Ice cream soda was served at soda fountains, along with various other early "soda water" recipes like the Garden Sass Sundae (rhubarb) or the Oh-Oh-Cindy Sundae (strawberry ice cream topped with chocolate syrup, chopped nuts, whipped cream and candied cherries). During that same time frame, grain-feeding of cattle during low pasture months made milk increasingly available year-round. The invention of milking machines lowered production costs. Pasteurization, homogenization, evaporation, condensation, and refrigeration along with glass milk bottles, wax-paper cartons, and then plastic bottles made milk increasingly available and safe for urban consumers. Milk became a staple food item and an increasingly important ingredient in American cuisine. Examples include the root beer float and the milkshake. Pork was a staple of the rural diet through the Southern and Midwestern United States. Lard was used for baking, frying and even as a seasoning. Major railroads featured upscale cuisine in their dining cars. Restaurant chains emerged with standardized decor and menus, including the Fred Harvey restaurants along the route of the Santa Fe Railroad in the Southwest. World War II and later The Food and Nutrition Board of the National Academy of Science established the first set of "Recommended Dietary Allowances" in 1941. In 1943, the US War Foods Administration issued the War Food Order No. 1, which made enriched bread the temporary law of the land. In 1945 George Stigler published an article on "The cost of subsistence" which described the so-called Stigler diet, his solution to the problem of providing a diet that met the RDA at a minimum cost. The logistical requirements of the US military during WW2 and the Korean War spurred the development and growth of the processed foods industry in the US. These wars encouraged the production of shelf-stable ingredients processed on a vast industrial scale. Examples include powdered milk, powdered eggs, potato flakes, and frozen concentrated orange juice. After the war, low-cost, highly processed foods became one of the foundational elements of an era of mass prosperity. Many companies in the American food industry developed new products requiring minimal preparation, such as frozen entrees. One such example is the TV dinner in which a multi-course meal was assembled in aluminum packaging in a food factory and flash frozen, then reheated at home in a thermal oven to be served while watching TV. Convenience foods of the era were designed to simplify home preparation. One example is macaroni & cheese created using a powdered artificial cheese product that is reconstituted at home with fresh milk. Newspapers and magazines ran recipe columns, aided by research from corporate kitchens, which were major food manufacturers like General Mills, Campbell's, and Kraft Foods. For example, General Mills Betty Crocker's Cookbook, first published in 1950, was a popular book in American homes. Highly processed foods of the mid-20th century included novelty elements like multi-colored Jell-O using various chemical food colorings, prepared breakfast cereals marketed to children with large amounts of sugar and artificial colors (e.g. Froot Loops). Fruit-flavored punches made with artificial fruit flavorings (e.g. Tang, Hi-C). Mid-20th-century foods also added novelty packaging elements like spray cheese in an aerosol can, pimento-stuffed olives, and drink pouches. The development of the microwave oven resulted in the creation of industrial food products and packaging intended to take advantage of the opportunities and overcome the unique challenges of that technology. Microwave popcorn is an example of such a product. Throughout the second half of the 20th century the US commercial food system has become increasingly dependent on subsidized maize (corn) production to provide feed for livestock and ingredients for human foods such as high-fructose corn syrup. It is estimated that the typical American gets 70 percent of their carbon intake from maize (corn) sources. The last half of the 20th century saw the development of controversial technological innovations intended to lower the cost of, improve the quality of, or increase the safety of commercial food including: food irradiation, genetically modified organisms, livestock treated with antibiotics/hormones, and concentrated animal feeding operations. Activists have raised concerns about the wholesomeness, safety, or humaneness of these innovations and recommend alternatives such as organic produce, veganism/vegetarianism, and locavore diets. Fast-food restaurants with standardized product and franchised service models began to appear and spread with the development of the highway system. White Castle (1916) was one of the first examples. Franchising was introduced in 1921 by A&W Root Beer. The McDonald brothers created their "Speedee Service System" in 1948. Other examples include Burger King, KFC, Wendy's, Pizza Hut, Little Caesars, Domino's Pizza and Papa John's Pizza. Ethnic influences One signature characteristic of American cooking is the fusion of multiple ethnic or regional approaches into completely new cooking styles. For example, spaghetti is Italian, while hot dogs are German; a popular meal, especially among young children, is spaghetti containing slices of hot dogs. Since the 1960s, Asian cooking has played a particularly large role in American fusion cuisine. Some dishes that are typically considered American have their origins in other countries. American cooks and chefs have substantially altered these dishes over the years, to the degree that the dishes now enjoyed around the world are considered to be American. Hot dogs and hamburgers are both based on traditional German dishes, but in their modern popular form they can be reasonably considered American dishes. Pizza is based on the traditional Italian dish, brought by Italian immigrants to the United States, but varies highly in style based on the region of development since its arrival. For example, Chicago style has focus on a thicker, taller crust, whereas a "New York Slice" is known to have a much thinner crust which can be folded. These different types of pizza can be advertised throughout the country and are generally recognizable and well-known, with some restaurants going so far as to import New York tap water from a thousand or more miles away to recreate the signature style in other regions. Some dishes that Americans think of as being of "foreign" in origin and/or associated with a particular immigrant group were in fact invented in America and customized to American tastes. For example General Tso's chicken was invented by Chinese or Taiwanese chefs working in New York in the early 1970s. The dish is unknown in China, except for a distant resemblance to a much spicier dish from Hong Kong said to have influenced the American version. The fortune cookie was likewise invented in California in the early 1900s and is known in Asia only as an American style food. A wave of celebrity chefs began with Julia Child and Graham Kerr in the 1970s, with many more following after the rise of cable channels like Food Network. Probably the best-known television chef was Child, who taught French cuisine in her weekly show, The French Chef. By the beginning of the 21st century, regional variations in consumption of meat began to reduce, as more meat was consumed overall. Saying they eat too much protein, the 2015–2020 Dietary Guidelines for Americans asked men and teenage boys to increase their consumption of underconsumed foods such as vegetables. New American During the 1980s, upscale restaurants introduced a mixing of cuisines that contain Americanized styles of cooking with foreign elements commonly referred to as New American cuisine, a type of fusion cuisine combining flavors from the melting pot of traditional American cooking techniques with those from other cultures, sometimes adding molecular gastronomy components. 21st century In the 21st century, vegan and vegetarian meals increased in popularity, with more restaurants catering to vegans and vegetarians. Regional cuisines In the present day, the modern cuisine of the United States is very regional in nature. Excluding Alaska and Hawaii, the terrain spans from east to west and more than from north to south. Northeast New England New England cuisine traces its roots to English cuisine and the Native American cuisine of the Abenaki, Narragansett, Niantic, Wabanaki, Wampanoag, and other native peoples. It also includes influences from French, Italian, and Portuguese cuisine, among others. It is characterized by the extensive use of potatoes, beans, dairy products and seafood. Corn, historically the main crop grown by Native American tribes in New England, continues to be grown in all New England states. It is traditionally used in hasty pudding, cornbread and corn chowder. Three prominent foodstuffs native to New England are maple syrup, cranberries and blueberries. Maine is the only state with a commercial wild blueberry industry, with 105 million pounds harvested in 2021. Initial European colonists came from East Anglia in England. East Anglian cookery included dishes like suet puddings, soda breads, and a few shellfish delicacies, and would have been quite simple in contrast to the dishes prepared in contemporary London. Most of this cuisine was one-pot cookery, which developed into such dishes as succotash, chowder, baked beans, and others. The most popular starches in New England cuisine include potatoes and cornmeal, and a few native breads like Anadama bread, johnnycakes, bulkie rolls, Parker House rolls, popovers, ployes, and New England brown bread. Because of the influence of New Englander health reformers, the most well known of whom is Sylvester Graham, this region is fairly conservative with its spices, but typical spices include nutmeg, ginger, cinnamon, cloves, and allspice, especially in desserts, and for savory foods, thyme, black pepper, sea salt, and sage. Typical condiments include maple syrup, grown from the native sugar maple, molasses, and cranberry sauce. The fruits of the region include the Vitis labrusca grapes used in grape juice made by companies such as Welch's, along with jelly, Kosher wine by companies like Mogen David and Manischewitz along with other wineries that make higher quality wines. Though not anywhere near as productive a region as the top three apple-producing regions, apples have been a staple of New England foodways since at least the 1640s, and it is here that a very high amount of heirloom varieties are found, many of them gaining renewed interest as part of locavore movements and the re-emergence of cider as a beverage of choice. Apples from New England would include varieties imported from their earliest in Europe and a few natives, like Baldwin, Lady, Mother, Pomme Grise, Porter, Roxbury Russet, Rhode Island Greening, Sops of Wine, Hightop Sweet, Peck's Pleasant, Titus Pippin, Westfield-Seek-No-Further, and Duchess of Oldenburg. Beach plums a small native species with fruits the size of a pinball, are sought after in summer to make into a jam. Cranberries are another fruit indigenous to the region, often collected in autumn in huge flooded bogs. Thereafter they are juiced so they can be drunk fresh for breakfast, or dried and incorporated into salads and quickbreads. Winter squashes like pumpkin and butternut squashes have been a staple for generations owing to their ability to keep for long periods over icy New England winters and being an excellent source of beta carotene; in summer, they are replaced with pattypan and zucchini, the latter brought to the region by immigrants from Southern Italy a century ago. Blueberries are a very common summertime treat owing to them being an important crop, and find their way into muffins, pies and pancakes. Historically New England and the other original 13 colonies were major producers of hard cider and the only reason why this changed were that immigrants from Western and Central Europe preferred beer, especially lagers, to apple based alcohol. In more recent years cider has made a roaring comeback nationwide, with New England being the first to break out of the box and with many pomologists scouring the woods for abandoned apple trees and heirloom varieties to add to the cider press. Angry Orchard is a local commercial brand that began in New Hampshire but has since skyrocketed in sales, with other large marques following suit around the land. Typical favorite desserts are quite diverse, and encompass hasty pudding, blueberry pie, whoopie pies, Boston cream pie, pumpkin pie, Joe Frogger cookies, hand-crafted ice cream, Hermit cookies, and the chocolate chip cookie, invented in Massachusetts in the 1930s. New England is noted for having a heavy emphasis on seafood, a legacy inherited from coastal tribes like the Wampanoag and Narragansett, who equally used the rich fishing banks offshore for sustenance. Favorite fish include cod, salmon, winter flounder, haddock, striped bass, pollock, hake, bluefish, and, in southern New England, tautog. All of these are prepared numerous ways, such as frying cod for fish fingers, grilling bluefish over hot coals for summertime, smoking salmon or serving a whole poached one chilled for feasts with a dill sauce, or, on cold winter nights, serving haddock baked in casserole dish with a creamy sauce and crumbled breadcrumbs as a top so it forms a crust. Clam cakes, a savory fritter based on chopped clams, are a specialty of Rhode Island. Also, a hard shell clam is unique to Rhode Island called the Quahoag which is used in clear chowders. Farther inland, brook trout, largemouth bass, and herring are sought after, especially in the rivers and icy finger lakes in upper New England where New Englanders will fly fish for them in summertime. Meat is present though not as prominent, and typically is either stewed in dishes like Yankee pot roast and New England boiled dinner or braised, as in a picnic ham; these dishes suit the weather better as summers are humid and hot but winters are raw and cold, getting below 0 °C for most of the winter and only just above it by March. The roasting of whole turkeys began here as a centerpiece for large American banquets, and like all other East Coast tribes, the Native American tribes of New England prized wild turkeys as a source of sustenance and later Anglophone settlers were enamored of cooking them using methods they knew from Europe: often that meant trussing the bird and spinning it on a string or spit roasting. Today turkey meat is a key ingredient in soups, and also a favorite in several sandwiches like the Pilgrim. For lunch, hot roast beef is sometimes chopped finely into small pieces and put on a roll with salami and American or provolone cheese to make a steak bomb. Bacon is often maple cured, and often bacon or salt pork drippings are an ingredient in corn chowder, a cousin of clam chowder. Veal consumption was prevalent in the North Atlantic States prior to World War II. A variety of linguiça is favored as a breakfast food, introduced by Portuguese fishermen and Brazilian immigrants. Dairy farming and its resultant products figure strongly on the ingredient list, and homemade ice cream is a summertime staple of the region: it was a small seasonal roadside stand in Vermont that eventually became the internationally famous Ben and Jerry's ice cream. Vermont is known for producing farmhouse style cheeses, especially a type of cheddar. The recipe goes all the way back to colonial times when English settlers brought the recipe with them from England and found the rocky landscape eminently suitable to making the cheese. Today Vermont has more artisanal cheese makers per capita than any other state, and diversity is such that interest in goat's milk cheeses has become prominent. Crustaceans and mollusks are also an essential ingredient in the regional cookery. Maine and Massachusetts, in more recent years, have taken to harvesting peekytoe crab and Jonah crab and making crab bisques, based on cream with 35% milkfat, and crabcakes out of them: often these were overlooked as bycatch of lobster pots by fishermen of the region, but in the past 30 years their popularity has firmly established them as a staple. They even appear on the menu as far south as to be out of the region in New York, where they are sold to four star restaurants in the form of cocktail claws. Whelks are eaten in salad, and lobster, which is indigenous to the coastal waters of the region and are a feature of many dishes, baked, boiled, roasted, and steamed, or simply eaten as a sandwich, chilled with mayonnaise and chopped celery in Maine and Massachusetts, or slathered with melted butter on Long Island and in Connecticut. Shellfish of all sorts are part of the diet, and shellfish of the coastal regions include little neck clams, sea scallops, blue mussels, oysters, soft shell clams, and razor shell clams. Much of this shellfish contributes to New England tradition, the clambake. The clambake as known today is a colonial interpretation of an American Indian tradition. In summer, oysters and clams are dipped in batter and fried, often served in a basket with french fries, or commonly on a wheaten bun as a clam roll. Oysters are otherwise eaten chilled on a bed of crushed ice on the half shell with mignonette sauce, and are often branded on where they were harvested. Large quahogs are stuffed with breadcrumbs and seasoning and baked in their shells, and smaller ones often find their way into clam chowder. Other preparations include clams casino, clams on the half shell served stuffed with herbs like oregano and streaky bacon. Southern New England, particularly along the coast, shares many specialties with the Mid-Atlantic, including especially dishes from Jewish and Italian-American cuisine. Coastal Connecticut is known for distinctive kinds of pizza, locally called apizza (pronounced locally as abeetz), differing in texture (thin and slightly blackened) and toppings (such as clams) from pizza further south in the so-called pizza belt, which stretches from New Haven, Connecticut southward through New York, New Jersey, and into Maryland. Delaware Valley and Mid-Atlantic The mid-Atlantic states comprise the states of New York, New Jersey, Delaware, Pennsylvania, and Northern Maryland. The oldest major settlement in this area of the country is found in the most populous city in the nation, New York, founded in 1625 by the Dutch. Today, it is a major cultural capital of the United States. The influences on cuisine in this region are extremely eclectic owing to the fact that it has been and continues to be a gateway for international culture as well as a gateway for new immigrants. Going back to colonial times, each new group has left their mark on homegrown cuisine and in turn the cities in this region disperse trends to the wider United States. In addition, cities like New York and Philadelphia have had the past influence of Dutch, Italian, German, Irish, British, and Jewish cuisines, and that continues to this day. Baltimore has become the crossroads between North and South, a distinction it has held since the end of the Civil War. A global power city, New York is well known for its diverse and cosmopolitan dining scene. Its restaurants compete fiercely for good reviews in the Food and Dining section of The New York Times, online guides, and Zagat's, the last of which is widely considered the premier American dining guide, published yearly and headquartered in New York. Many of the more complicated dishes with rich ingredients like Lobster Newberg, waldorf salad, vichyssoise, eggs benedict, and the New York strip steak were born out of a need to entertain and impress the well-to-do in expensive bygone restaurants like Delmonico's and still standing establishments like the Waldorf-Astoria Hotel. Modern commercial American cream cheese was developed in 1872. Since the first reference to an alcoholic mixed drink called a cocktail comes from New York State in 1803, it is not a surprise that there have been many cocktails invented in New York and the surrounding environs. Even today New York bars are noted for being highly influential in making national trends. Cosmopolitans, Long Island iced teas, Manhattans, Rob Roys, Tom Collins, Aviations, and Greyhounds were all invented in New York bars, and the gin martini was popularized in New York in speakeasies during the 1920s, as evidenced by its appearance in the works of New Yorker and American writer F. Scott Fitzgerald. Like its neighbor Philadelphia, many rare and unusual liquors and liqueurs often find their way into a mixologist's cupboard or restaurant wine list. New York State is the third most productive area in the country for wine grapes, just behind California and Washington. It has AVA's near the Finger Lakes, the Catskills, and Long Island, and in the Hudson Valley has the second-most productive area in the country for growing apples, making it a center for hard cider production, just like New England. Pennsylvania has been growing rye since Germans began to emigrate to the area at the end of the 17th century and required a grain they knew from Germany. Therefore, overall it is not unusual to find New York grown Gewürtztraminer and Riesling, Pennsylvania rye whiskey, or marques of locally produced ciders like Original Sin on the same menu. Since their formative years, New York, Philadelphia, and Baltimore have welcomed immigrants of every kind to their shores, and all three have been an important gateway through which new citizens to the general United States arrive. Traditionally natives have eaten cheek to jowl with newcomers for centuries as the newcomers would open new restaurants and small businesses and all the different groups would interact. Even in colonial days this region was a very diverse mosaic of peoples, as settlers from Switzerland, Wales, England, Ulster, Wallonia, Holland, Gelderland, the British Channel Islands, and Sweden sought their fortune in this region. This is very evident in many signature dishes and local foods, all of which have evolved to become American dishes in their own right. The original Dutch settlers of New York brought recipes they knew and understood from the Netherlands and their mark on local cuisine is still apparent today: in many quarters of New York their version of apple pie with a streusel top is still baked. In the colony of New Amsterdam, their predilection for waffles in time evolved into the American national recipe and forms part of a New York brunch. They also made coleslaw, originally a Dutch salad, but today accented with the later 18th-century introduction of mayonnaise. The doughnut began its life originally as a New York pastry that arrived in the 18th century as the Dutch olykoek, with later additions from other nations of Europe like the Italian zeppole, the Jewish/Polish pączki, and the German Berliner arriving in the 19th century to complete the variety found in modern doughnuts today. Crab cakes were once a kind of English croquette, but over time as spices have been added they and the Maryland crab feast became two of Baltimore's signature dishes. Fishing for blue crab is a favorite summer pastime in the waters off Maryland, New Jersey, and Delaware where they may grace the table at summer picnics. Other mainstays of the region have been present since the early years of American history, like oysters from Cape May, the Chesapeake Bay, and Long Island, and lobster and tuna from the coastal waters found in New York and New Jersey. Philadelphia Pepper Pot, a tripe stew, was originally a British dish but today is a classic of home cooking in Pennsylvania alongside bookbinder soup, a type of turtle soup. In the winter, New York pushcarts sell roasted chestnuts, a delicacy dating back to English Christmas traditions, and it was in New York and Pennsylvania that the earliest Christmas cookies were introduced: Germans introduced crunchy molasses-based gingerbread and sugar cookies in Pennsylvania, and the Dutch introduced cinnamon-based cookies, all of which have become part of the traditional Christmas meal. Scrapple was originally a type of savory pudding that early Pennsylvania Germans made to preserve the offal of a pig slaughter. The Philadelphia soft pretzel was originally brought to Eastern Pennsylvania in the early 18th century, and later, 19th-century immigrants sold them to the masses from pushcarts to make them the city's best-known bread product, having evolved into its own unique recipe. After the 1820s, new groups began to arrive and the character of the region began to change. There had been some Irish from Ulster prior to 1820, however largely they had been Protestants with somewhat different culture and (often) a different language than the explosion of emigrants that came to Castle Garden and Locust Point in Baltimore in their masses starting in the 1840s. The Irish arrived in America in a rather woeful state, as Ireland at the time was often plagued by some of the worst poverty in Europe and often heavy disenfranchisement among the masses. Many of them arrived barely alive having ridden coffin ships to the New World, very sick with typhus and gaunt from prolonged starvation. In addition, they were the first to face challenges other groups did not have: they were the first large wave of Catholics. They faced prejudice for their faith and the cities of Philadelphia, New York, and Baltimore were not always set up for their needs. For example, Catholic bishops in the U.S. mandated until the 1960s that all Catholics were forbidden from eating red meat on Fridays and during Lent, and attending Mass sometimes conflicted with work as produce and meat markets would be open on high holy days; this was difficult for Irishmen supporting families since many worked as laborers. Unsurprisingly, many Irishmen also found their fortunes working as longshoremen, which would have given their families access to fish and shellfish whenever a fisherman made berth, which was frequent on the busy docks of Baltimore and New York. Though there had been some activity in Baltimore in founding a see earlier by the Carrolls, the Irish were the first major wave of Catholic worship in this region, and that meant bishops and cardinals sending away to Europe for wine. Wine, with water, is consecrated as part of the Catholic Mass. Taverns had existed prior to their emigration to America in the region, though the Irish brought their particular brand of pub culture and founded some of the first saloons and bars that served Dublin style stout and red ale; they brought with them the knowledge of single-malt style whiskey and sold it. The Irish were the first immigrant group to arrive in this region in massive millions, and these immigrants also founded some of the earliest saloons and bars in this region, of which McSorley's is a still operating example. It was also in this region that the Irish introduced something that today is a very important festival in American culture that involves a large amount of food, drink, and merry making: Halloween. In England and Wales, where prior immigrants had come from, the feast of All Hallows Eve had died out in the Reformation, dismissed as superstition and excess having nothing to do with the Bible and often replaced with the festival of Guy Fawkes Night. Other immigrant groups like the Germans preferred to celebrate October 31 as Reformation Day, and after the American Revolution all of the above were less and less eager to celebrate the legacy of an English festival given they had fought against Great Britain for their independence. The Catholicism of the Irish demanded attendance at church on November 1 and charity and deeds, not just faith, as a cornerstone of dogma, and many of their older traditions survived the Reformation and traveled with them. Naturally, they went door-to-door to collect victuals for masked parties as well as gave them out, like nuts to roast on the fire, whiskey, beer, or cider, and barmbracks; they also bobbed for apples and made dumb cakes. Later in the century they were joined by Scots going guising, children going door-to-door to ask for sweets and treats in costume. From the Mid-Atlantic this trend spread to be nationwide and evolved into American children trick-or-treating on October 31 wearing costumes and their older counterparts having wild costume parties with various foods and drinks such as caramel apples, candy apples, dirt cakes, punch, cocktails, cider (both alcoholic and non,) pumpkin pie, candy corn, chocolate turtles, peanut brittle, taffy, tipsy cake, and copious buckets full of candy; children carving jack-o-lanterns and eating squash derived foods derive from Halloween's heritage as a harvest festival and from Irish and Scottish traditions of carving turnips and eating root vegetables at this time of year. Bobbing for apples has survived to the present day as a Halloween party classic game, as has a variation on the parlor game of trying to grab an apple hanging from the ceiling blindfolded: it has evolved into trying to catch a donut in one's teeth. Immigrants from Southern Europe, namely Sicily, Campania, Lazio, and Calabria, appeared between 1880 and 1960 in New York, New Jersey, Pennsylvania, and Eastern Maryland hoping to escape the extreme poverty and corruption endemic to Italy. Typically none of them spoke English, but rather dialects of Italian and had a culture that was more closely tied to the village they were born in than the high culture only accessible to those who could afford it at this time; many could not read or write in any language. They were employed in manual labor or factory work but it is because of them that dishes like spaghetti with meatballs, New York–style pizza, calzones, and baked ziti exist, and Americans of today are very familiar with semolina based pasta noodles. Their native cuisine had less of an emphasis on meat, as evidenced by dishes they introduced like pasta e fagioli and minestrone, but the dishes they created in America often piled it on as a sign of wealth and newfound prosperity since for the first time even cheap cuts of it were affordable. The American recipe for lasagna is proof of this, as mostly it is derived from the Neapolitan version of the dish with large amounts of meat and cheese. New York–style hot dogs came about with German-speaking emigrants from Austria and Germany, particularly with the frankfurter sausage and the smaller wiener sausage; Jews would also contribute here by introducing the kosher version of these sausages, made of beef rather than pork. Today, the New York–style hot dog with sauerkraut, mustard, and the optional cucumber pickle relish is such a part of the local fabric, that it is one of the favorite comestibles of New York and both the pork and the beef versions are beloved. Hot dogs are a typical street food sold year round in all but the most inclement weather from thousands of pushcarts. As with all other stadiums in Major League Baseball they are an essential for New York Yankees and the New York Mets games though it is the local style of preparation that predominates without exception. Hot dogs are also the focus of a televised eating contest on the Fourth of July in Coney Island, at Nathan's Famous, one of the earliest hot dog stands opened in the United States in 1916 by Nathan Handwerker. Handwerker was a Jewish man who emigrated from what is now Ukraine in 1912 and whose influence is felt today around the world. Coney Island is most famous for being a traditional boardwalk amusement park and the site of the world's first rollercoaster, a precursor of modern theme parks. Hot dogs are a staple of amusement parks 100 years later. A summertime treat, Italian ice, began its life as a sweeter adaptation of the Sicilian granita that was strictly lemon-flavored and brought to New York and Philadelphia. Its Hispanic counterpart, piragua, is a common shaved-ice treat brought to New York by Puerto Ricans in the 1930s. Unlike the original dish which included flavors like tamarind, mango, coconut, piragua is evolving to include flavors like grape and cherry, fruits which are impossible to grow in the tropical Puerto Rican climate and get exported back to the island from New York. Taylor Ham, a meat delicacy of New Jersey, first appeared around the time of the Civil War and today is often served for breakfast with eggs and cheese on a kaiser roll, a variant of a roll brought to the area by Austrians in the second half of the 19th century, now commonly used for sandwiches at lunchtime, often topped with poppyseeds. This breakfast meat is generally known as pork roll in southern New Jersey and Philadelphia, and Taylor Ham in northern New Jersey. Other dishes came about during the early 20th century and have much to do with delicatessen fare, set up largely by Jewish immigrants from Eastern Europe who came to America incredibly poor, often illiterate in any other language but Yiddish, and often banished from mainstream society in their place of origin for centuries. Most often they were completely unable to partake in the outdoor food markets that the general population utilized as most of the food for sale was not kosher. The influence of European Jewry before their destruction in the Holocaust on modern mid-Atlantic cooking remains strong and reinforced by their many descendants in the region. These currently form the largest concentration of Jews outside Tel Aviv and are very integrated into the local mainstream of New York in particular. American-style pickles, now a common addition to hamburgers and sandwiches, were brought by Polish Jews, and Austro-Hungarian Jews brought a recipe for almond horns that now is a common regional cookie, diverting from the original recipe in dipping the ends in dark chocolate. New York–style cheesecake has copious amounts of cream and eggs because animal rennet is not kosher and so could not be sold to a large number of the deli's clientele. New York inherited its bagels and bialys from Jews, as well as Challah bread. Pastrami first entered the country via Romanian Jews, and is a feature of many sandwiches, often eaten on marble rye, a bread that was born in the mid-Atlantic. Whitefish salad, lox, and matzoh ball soup are now standard fare made to order at local diners and delicatessens, but started their life as foods that made up a strict dietary code. Rugelach cookies and hamentashen are sweet staples still sold to the general public, but came to New York over a century ago with Ashkenazi Jews along with Jewish rye. Many of their dishes passed into the mainstream enough that they became standard fare in diners by the end of the 20th century, a type of restaurant that is now the most common in the region, and the subject matter of the artist Edward Hopper. In the past this sort of establishment was the haven of the short-order cook grilling or frying simple foods for the working man. Today typical service includes staples from this large region like beef on weck, Manhattan clam chowder, the club sandwich, Buffalo wings, Philadelphia cheesesteak, the black and white cookie, shoofly pie, snapper soup, Smith Island cake, blackout cake, grape pie, milkshakes, and the egg cream, a vanilla or chocolate fountain drink with a frothy top and fizzy taste. As in Hopper's painting from 1942, many of these businesses are open 24 hours a day. Midwest This region today comprises the states near the Great Lakes and also the Great Plains; much of it is prairie with very flat terrain. Winters are bitterly cold, windy, and wet. Midwestern cuisine today is a very eclectic and odd mix and match of foodways, covering everything from Kansas City–style barbecue to the Chicago-style hot dog, though many of its classics are very simple, hearty fare. This region was mostly untouched by European and American settlers until after the American Revolutionary War, and excepting Missouri and the heavily forested states near the Great Lakes, was mainly populated by nomadic tribes like the Sioux, Osage, Arapaho, and Cheyenne. As with most other American Indian tribes, these tribes consumed the Three Sisters of beans, maize, and squash, but also for thousands of years followed the herds of bison, hunting them on foot and later on horseback, typically using bow and arrow. There are buffalo jumps dating back nearly 10,000 years and several photographs and written accounts of trappers and homesteaders attesting to their dependence on the buffalo and to a lesser degree elk. After nearly wiping out elk and bison, this region has taken to raising bison alongside cattle for their meat and at an enormous profit, making them into burgers and steaks. Often that means harsh blizzards especially near the Great Lakes where Arctic winds blow off of Canada, where ice on rivers and lakes freezes thick enough for ice hockey, and for ice fishing for pike, walleye and panfish to be ubiquitous. In Minnesota, Wisconsin, and Michigan, they often become part of the local fish fry. The primary meats here are beef and poultry, since the Midwest has been raising turkeys, chickens, and geese for over 150 years. Chickens have been common for so long that the Midwest has several native breeds that are prized for both backyard farming and for farmer's markets, such as the Buckeye and Wyandotte. One, Billina, appears as a character in the second book of the Oz series by L. Frank Baum. Favorite fruits of the region include some native plants inherited from Native American tribes like the pawpaw, and American persimmons are also highly favored. As in the American South, pawpaws are the region's largest native fruit, about the size of a mango, often found growing wild come September; they are made into preserves and cakes and command quite a price at farmer's markets in Chicago. The American persimmon is often smaller than its Japanese cousin, about the size of a small plum, but in the Midwest and parts of the East it is the main ingredient in the steamed persimmon pudding, topped with crème anglaise. Other crops inherited from the Native Americans include wild rice, which grows on the banks of lakes and is a local favorite for fancy meals and today often used in stuffing for Thanksgiving. Typical fruits of the region are cold-weather crops. Once it was thought that its winters were too harsh for apples, but a breeder in Minnesota produced the Wealthy apple and it became the third-most productive region for apple growing in the country, with local varieties comprising Wolf River, Enterprise, Melrose, Paula Red, Rome Beauty, Honeycrisp, and the Red Delicious. Cherries are important to Michigan and Wisconsin grows many cranberries, a legacy of early-19th-century emigration of New England farmers. Crabapple jelly is a favorite condiment of the region. The influence of German, Scandinavian, and Slavic peoples on the northern portion of the region is very strong; many emigrated to Wisconsin, Minnesota, Michigan, Ohio, and Illinois in the 19th century to take advantage of jobs in the meatpacking business as well as being homesteaders and tradesmen. Bratwurst is a very common sausage eaten at tailgate parties for the Green Bay Packers, Chicago Bears, or Detroit Lions, often served boiled in lager beer with sauerkraut, different from many of the recipes currently found in Germany. Polish sausage, in particular a locally invented type of kielbasa, is essential for sporting events in Chicago: Chicago today has approximately 200,000 Polish speakers and has had a similar population for over 100 years. When Poles came to Chicago and surrounding cities from Europe, they brought with them long ropes of kielbasa, cabbage rolls, and pierogi. Poles that left Poland after the fall of the Berlin Wall and descendants of earlier immigrants still make them, and they remain common in local diners and delis. Today alongside the pierogi, the sausage is served on a long roll with mustard like a hot dog or as a Maxwell Street Polish, a sandwich with caramelized onions. In Cleveland, the same sausage is served in the form of the Polish boy, a sandwich made of french fries, spicy barbecue sauce, and coleslaw. Unlike cities in the East where the hot dog alone is traditional, fans of the Cleveland Indians, Detroit Tigers, Chicago Cubs, and Milwaukee Brewers favor two or three different kinds of sausage sold in the pushcarts outside the stadium. The hot dogs themselves tend to follow the Chicago style, with mustard and pickled vegetables. In Cincinnati, where the Cincinnati Reds play, there is a competitor in Cincinnati chili. Invented by Macedonian immigrants, it includes spaghetti as its base, chili with a Mediterranean-inspired spice mix, and cheddar cheese; the chili itself is often a topping for local hot dogs at games. In the Midwest and especially Minnesota, the tradition of the church potluck is a gathering where local foods reign, and has been since the era of the frontier; pioneers often needed to pool resources to have a celebration in the 19th century and that simply never changed. Nowhere is this more clear than with the hotdish, a type of casserole believed to have derived from a Norwegian recipe, it is usually topped with potatoes or tater tots. Next to the hotdish at potlucks usually glorified rice is found, a kind of rice pudding mixed with crushed pineapple and maraschino cherries. Next to that is the booyah, a thick soup made of meat, vegetables, and seasonings that is meant to simmer on the stove for up to two days. Lefse, traditionally a Scandinavian flatbread, has been handed down to descendants for over a hundred years and is common on the table. Behind that is venison, a popular meat around the Great Lakes and often eaten as steaks, sandwiches, and crown roasts for special events. Within Wisconsin, Minnesota and the Dakotas, tiger meat, a dish similar to steak tartare, is common. Last on the table are the dessert bars and brownies, created originally in 1898 in Chicago, now a global food and international favorite. Further south, barbecue has its own style in places in Kansas City and St. Louis different from the South and American West. Kansas City and St. Louis were and are important hubs for the railroad that connected the plains with the Great Lakes and cities farther east, like Philadelphia. At the turn of the 19th century, the St. Louis area, Omaha, and Kansas City had huge stockyards, waystations for cattle and pigs on their way east to the cities of the coast and north to the Great Lakes. They all had large growing immigrant and migrant populations from Europe and the South respectively, so the region has developed unique styles of barbecue. St. Louis–style barbecue favors a heavy emphasis on a sticky sweet barbecue sauce. Its standbys include the pork steak, a cut taken from the shoulder of the pig, grilled then slowly stewed in a pan over charcoal; crispy snoots, a cut from the cheek and nose of the pig that is fried up like cracklins and eaten dipped in sauce; pork spare ribs; and a mix of either beer-boiled bratwurst or grilled Italian sausage, flavored with fennel. Dessert is usually something like gooey butter cake, invented in the city in the 1930s. Kansas City–style barbecue uses several different kinds of meat, more than most styles of American barbecue—turkey, mutton, pork, and beef to name a few—but is distinct from St. Louis in that the barbecue sauce adds molasses in with the tomato-based recipe and typically has a more tart taste. Traditionally, Kansas City uses a low-and-slow method of smoking the meat in addition to just stewing it in the sauce. It also favors using hickory wood for smoking and continual watering or layering of the sauce while cooking to form a glaze; with burnt ends this step is necessary to create the "bark" or charred outer layer of the brisket. Southern United States When referring to the American South as a region, typically it should indicate Southern Maryland and the states that were once part of the Old Confederacy, with the dividing line between the East and West jackknifing about 100 miles west of Dallas, Texas, and mostly south of the old Mason–Dixon line. Cities found in this area include New Orleans, Atlanta, Washington, D.C., Memphis, Charleston, and Charlotte with Houston, Texas being the largest. The Florida Panhandle is usually considered part of the South, but the Florida peninsula (especially its lower half) is not. These states are much more closely tied to each other and have been part of U.S. territory for much longer than states much farther west than East Texas, and in the case of food, the influences and cooking styles are strictly separated as the terrain begins to change to prairie and desert from bayou and hardwood forest. This section of the country has some of the oldest known U.S. foodways, with some recipes almost 400 years old. Native American influences are still quite visible in the use of cornmeal as an essential staple and found in the Southern predilection for hunting wild game, in particular wild turkey, deer, woodcock, and various kinds of waterfowl; for example, coastal North Carolina is a place where hunters will seek tundra swan as a part of Christmas dinner; the original English and Scottish settlers would have rejoiced at this revelation owing to the fact that such was banned among the commoner class in what is now the United Kingdom, and naturally, their descendants have not forgotten. Native Americans also consumed turtles and catfish, specifically the snapping turtle, the alligator snapping turtle, and blue catfish. Catfish are often caught with one's bare hands, gutted, breaded, and fried to make a Southern variation on English fish and chips and turtles are turned into stews and soups. Native American tribes of the region such as the Cherokee or Choctaw often cultivated or gathered local plants like pawpaw, maypop and several sorts of squashes and corn as food. They also used spicebush and sassafras as spices, and the aforementioned fruits are still cultivated as food in the South. Maize is to this day found in dishes for breakfast, lunch and dinner in the form of grits, hoecakes, baked cornbread, and spoonbread, and nuts like the hickory, black walnut and pecan are commonly included in desserts and pastries as varied as mince pies, pecan pie, pecan rolls and honey buns (both are types of sticky bun), and quick breads, which were themselves invented in the South during the American Civil War. Peaches have been grown in this region since the 17th century and are a staple crop as well as a favorite fruit, with peach cobbler being a signature dessert. Early history European influence began soon after the settlement of Jamestown in 1607 and the earliest recipes emerged by the end of the 17th century. Specific influences from Europe were quite varied, and they remain traditional and essential to the modern cookery overall. German speakers often settled in the Piedmont on small farms from the coast, and invented an American delicacy that is now nationally beloved, apple butter, based on their recipe for apfelkraut, and later they introduced red cabbage and rye. From the British Isles, an enormous amount of influence was bestowed upon the South, specifically foodways from 17th- and 18th-century Ulster, the borderlands between England and Scotland, the Scottish Highlands, portions of Wales, the West Midlands, the West Country, Black Country and Southern England. Settlers bound for America fled the tumult of the Civil War, Ulster and the Highland Clearances. Often ships' manifests show their belongings nearly always included cookpots or bakestones and seed stock for plants like peaches, plums, and apples to grow orchards which they planted in their hundreds. Each group brought foods and ideas from their respective regions. Settlers from Ireland and Scotland were well known for creating peatreak and poitín, strong hard liquor based on fermenting potatoes or barley. In time they came up with a method for distilling a corn mash with added sugar and aging in charred barrels made of select hardwoods, which created a whiskey with a high proof. This gave birth to American whiskey and Kentucky bourbon, and its cousins moonshine and Everclear. Closer to the coast, 18th-century recipes for English trifle turned into tipsy cakes, replacing the sherry with whiskey and their recipe for pound cake, brought to the South around the same time, still works with American baking units: one pound sugar, one pound eggs, one pound butter, one pound flour. Common features Pork is the popular choice in 80% of Southern style barbecue and features in other preparations like sausages and sandwiches. For most Southerners in the antebellum period, corn and pork were staples of the diet. Country sausage is an ingredient in the Southern breakfast dish of biscuits and gravy. Country ham is often served for breakfast and cured with salt or sugar and hickory-smoked. Accompanying many meals is the southern style fluffy biscuit, where the leavening agent is baking soda and often includes buttermilk, and for breakfast they often accompany country ham, grits, and scrambled eggs. Desserts Desserts in the South tend to be quite rich and very much a legacy of entertaining to impress guests, since a Southern housewife was (and to a degree still is) expected to show her hospitality by laying out as impressive a banquet as she is able to manage. Desserts are vast and encompass Lane cake, sweet potato pie, peach cobbler, pecan pie, hummingbird cake, Jefferson Davis pie, peanut brittle, coconut cake, apple fritters, peanut cookies, Moravian spice cookies, chess pie, doberge cake, Lady Baltimore cake, bourbon balls, and caramel cake. American-style sponge cakes tend to be the rule rather than the exception as is American buttercream, a place where Southern baking intersects with the rest of the United States. Nuts like pecan and hickory tend to be revered as garnishes for these desserts, and they make their way into local bakeries as fillings for chocolates. Cajun and Creole cuisine of Louisiana In Louisiana, cooking methods have more in common with rustic French cuisines of the 17th and 18th century than anything ever found at the French court in Versailles or the bistros of 19th- and 20th-century Paris; this is especially true of Cajun cuisine. Cajun French is more closely related to dialects spoken in Northern Maine, New Brunswick, and to a lesser degree Haiti than anything spoken in modern France, and likewise their terminology, methodology, and culture concerning food is much more closely related to the styles of these former French colonies even today. Unlike other areas of the South, Cajuns were and still are largely Catholics and thus much of what they eat is seasonal; for example pork is an important component of the Cajun boucherie (a large community event where the hog is butchered, prepared with a fiery spice mix, and eaten snout to tail) but it is never consumed in the five weeks of Lent, when such would be forbidden. Cajun cuisine tends to focus on what is locally available, historically because Cajuns were often poor, illiterate, independent farmers and not plantation owners but today it is because such is deeply imbedded in local culture. Boudin is a type of sausage found only in this area of the country, and it is often by far more spicy than anything found in France or Belgium. Chaudin is unique to the area, and the method of cooking is comparable to the Scottish dish haggis: the stuffing includes onions, rice, bell peppers, spices, and pork sewn up in the stomach of a pig, and served in slices piping hot. Crawfish are a staple of the Cajun grandmother's cookpot, as they are abundant in the bayous of Southern Louisiana and a main source of livelihood, as are blue crabs, shrimp, corn on the cob, and red potatoes, since these are the basic ingredients of the Louisiana crawfish boil. New Orleans has been the capital of Creole culture since before Louisiana was a state. This culture is that of the colonial French and Spanish that evolved in the city of New Orleans, which was and still is quite distinct from the rural culture of Cajuns and dovetails with what would have been eaten in antebellum Louisiana plantation culture long ago. Cooking to impress and show one's wealth was a staple of Creole culture, which often mixed French, Spanish, Italian, German, African, Caribbean and Native American cooking methods, producing rich dishes like oysters bienville, pompano en papillote, and even the muffaletta sandwich. However, Louisiana Creole cuisine tends to diverge from the original ideas brought to the region in ingredients: profiteroles, for example, use a near identical choux pastry to that which is found in modern Paris but often use vanilla or chocolate ice cream rather than custard as the filling, pralines nearly always use pecan and not almonds, and bananas foster came about when New Orleans was a key port for the import of bananas from the Caribbean Sea. Gumbos tend to be thickened with okra, or the leaves of the sassafrass tree. Andouille is often used, but not the andouille currently known in France, since French andouille uses tripe whereas Louisiana andouille is made from a Boston butt, usually inflected with pepper flakes, and smoked for hours over pecan wood. Other ingredients that are native to Louisiana and not found in the cuisine of modern France would include rice, which has been a staple of both Creole and Cajun cooking for generations, and sugarcane, which has been grown in Louisiana since the early 1800s. Ground cayenne pepper is a key spice of the region, as is the meat of the American alligator, something settlers learned from the Choctaws and Houma. The maypop plant has been a favorite of Southerners for 350 years; it gives its name to the Ocoee River in Tennessee, a legacy of the Cherokees, and in Southern Louisiana it is known as liane de grenade, indicating its consumption by Cajuns. It is a close relative of the commercial passionfruit, similar in size, and is a common plant growing in gardens all over the South as a source of fresh summertime fruit. African American influences West African influences came with enslaved peoples from Ghana, Benin, Mali, Congo, Angola, Sierra Leone, Nigeria, and other portions of the Gold Coast, and the mark Africans and their descendants, the African Americans, have made on Southern food is strong today and an essential addition to the Southern table. Crops like okra, sorghum, sesame seeds, eggplant, and many different kinds of melons were brought with them from West Africa along with the incredibly important introduction of rice to the Carolinas and later to Texas and Louisiana, whence it became a staple grain of that region and still remains a staple in those areas today, found in dishes like Hoppin John, purloo, and Charleston red rice. Like the poorer indentured servants that came to the South, slaves often got the leftovers of what was slaughtered for the consumption of the master of the plantation and so many recipes had to be adapted for offal, like pig's ears and fatback though other methods encouraged low and slow methods of cooking to tenderize the tougher cuts of meat, like braising, smoking, and pit roasting, the last of which was a method known to West Africans in the preparation of roasting goat. Peanut soup is one of the oldest known recipes brought to Virginia by Africans and over time, through their descendants, it has become creamier and milder tasting than the original. Florida cuisine Certain portions of the South often have their own distinct subtypes of cuisine owing to local history and landscape. Floridian cuisine, for example, has a distinct way of cooking that includes different ingredients, especially south of Tampa and Orlando. Spain had control of the state until the early 19th century and used the southern tip as an outpost to guard the Spanish Main beginning in the 1500s, but Florida kept and still maintains ties with the Caribbean Sea, including the Bahamas, Haiti, Cuba, Puerto Rico, the Dominican Republic, and Jamaica. South of Tampa, there are and have been for a long time many speakers of Caribbean Spanish, Haitian French, Jamaican Patois, and Haitian Creole and each Caribbean culture has a strong hold on cooking methods and spices in Florida. In turn, each mixes and matches with the foodways of the Seminole tribe and Anglophone settlers. Thus, for almost 200 years, Floridian cooking has had a more tropical flavor than any other Southern state. Allspice, a spice originally from Jamaica, is an ingredient found in spice mixes in summer barbecues along with ginger, garlic, scotch bonnet peppers, sea salt, and nutmeg; in Floridian cooking this is often a variant of Jamaican jerk spice. Coconuts are grown in the areas surrounding Miami and are shipped in daily through its port for consumption of the milk, meat, and water of the coconut. Bananas are not just the yellow Cavendish variety found in supermarkets across America: in Florida they are available as bananitos, colorados, plátanos, and maduros. The first of these is a tiny miniature banana only about 4-5 inches (10–13 cm) in length and it is sweet. The second has a red peel and an apple-like aftertaste, and the third and fourth are used as a starch on nearly every Caribbean island as a side dish, baked or fried: all of the above are a staple of Florida outdoor markets when in season and all have been grown in the Caribbean for almost 400 years. Mangoes are grown as a backyard plant in Southern Florida and otherwise are a favorite treat coming in many different shapes in sizes from Nam Doc Mai, brought to Florida after the Vietnam War, to Madame Francis, a mango from Haiti. Sweetsop and soursop are popular around Miami, but nearly unheard of in other areas of the South. Citrus is a major crop of Florida, and features at many breakfast tables and many markets, with the height of the season near the first week of January. Hamlin oranges are the main cultivar planted, and from this crop the rest of the United States and to a lesser extent Europe gets orange juice. Other plantings would include grapefruits, tangerines, clementine oranges, limes, and even a few more rare ones, like cara cara navels, tangelos, and the Jamaican Ugli fruit. Tomatoes, bell peppers, habanero peppers, and figs, especially taken from the Florida strangler fig, complete the produce menu. Blue crab, conch, Florida stone crab, red drum, dorado, and marlins tend to be local favorite ingredients. Dairy is available in this region, but it is less emphasized due to the year round warmth. Traditional key lime pie, a dessert from the islands off the coast of Miami, is made with condensed milk to form the custard with the eye wateringly tart limes native to the Florida Keys in part because milk would spoil in an age before refrigeration. Pork in this region tends to be roasted in methods similar to those found in Puerto Rico and Cuba, owing to mass emigration from those countries in the 20th century, especially in the counties surrounding Miami. Orange blossom honey is a specialty of the state, and is widely available in farmer's markets. Caribbean lobster is a favorite special meal eagerly sought after by Floridians as it is found as far north as Fort Myers: spear diving and collecting them from reefs in the Florida Keys and near rocky shoals is a common practice of local scuba divers. Other small game Ptarmigan, grouse, crow, blackbirds, dove, duck and other game fowl are consumed in the United States. In the American state of Arkansas, beaver tail stew is consumed in Cotton town. Squirrel, raccoon, possum, bear, muskrat, chipmunk, skunk, groundhog, pheasant, armadillo and rabbit are also consumed in the United States. Cuisine in the West Cooking in the American West gets its influence from Native American and Hispanophone cultures, as well as later settlers that came in the 19th century: Texas, for example, has some influence from Germany in its choice of barbecue by using sausages. Another instance can be found in the Northwestern region, which encompasses Oregon, Washington, and Northern California. All of the aforementioned rely on local seafood and a few classics of their own. In New Mexico, Colorado, Nevada, Arizona, Utah, West Texas, and Southern California, Mexican flavors and influences are extremely common, especially from the Mexican states of Chihuahua, Baja California, and Sonora. Northwest The Pacific Northwest as a region includes Alaska and the state of Washington near the Canada-US border and terminates near Sacramento, California. Here, the terrain is mostly temperate rainforest on the coast mixed with pine forest as one approaches the Canada-US border inland. One of the core favorite foodstuffs is Pacific salmon, native to many of the larger rivers of the area and often smoked or grilled on cedar planks. In Alaska, wild game like ptarmigan and moose meat feature extensively since much of the state is wilderness. Fresh fish like steelhead trout, Pacific cod, Pacific halibut, and pollock are fished for extensively and feature on the menu of many restaurants, as do a plethora of fresh berries and vegetables, like Cameo apples from Washington state, the headquarters of the U.S. apple industry, cherries from Oregon, blackberries, and marionberries, a feature of many pies. Hazelnuts are grown extensively in this region and are a feature of baking, such as in chocolate hazelnut pie, an Oregon favorite, and Almond Roca is a local candy. This region is also heavily dominated by some notable wineries producing a high-quality product. Like its counterpart on the opposite coast to the East, there is a grand variety of shellfish in this region. Geoducks are a native species of giant clam that have incredibly long necks; they are eaten by the bucketful and shipped to Asia for millions of dollars as they are believed to be an aphrodisiac. Gaper clams are a favorite food, often grilled or steamed in a sauce. Native California abalone is protected as a food source, and a traditional foodway predating settlement by whites, today featuring heavily in the cooking of fine restaurants as well as in home cooking, in mirin-flavored soups (the influence of Japanese cooking is strong in the region) noodle dishes and on the barbecue. Native Olympia oysters are served on the half shell as well as the Kumamoto oyster, introduced by Japanese immigrants and a staple at dinner as an appetizer. California mussels are a delicacy of the region, and have been a feature of the cooking for generations. There is evidence that Native American tribes consumed them up and down the California coast for centuries. Crabs are a delicacy, and included in this are Alaskan king crab, red crab, yellow crab, and Dungeness crab. Californian and Oregonian sportsmen pursue the last three extensively using hoop nets, and prepare them in a multitude of ways. Alaskan king crab, able to grow as large as 10 kg, is often served steamed for a whole table with lemon-butter sauce or put in chunks of salad with avocado, and native crabs are the base of dishes like the California roll, cioppino, a tomato-based fisherman's stew, and Crab Louie, another kind of salad native to San Francisco. Favorite grains are mainly wheat, and the region is known for sourdough bread. Cheeses of the region include Humboldt Fog, Cougar Gold and Teleme. Southwest and Southern California The states of the Four Corners (Arizona, New Mexico, Colorado, and Utah) plus Nevada, Southern California, and West Texas make up a large chunk of the United States. There is a distinct Hispanic accent to the cookery here, with each having cultural capitals in Albuquerque, Denver, Las Vegas, Los Angeles, Phoenix, Santa Fe, San Diego, and Tucson. For centuries, prior to California's statehood in the 1850s, it was part of the Spanish Empire, namely Alta California (modern California), Santa Fe de Nuevo México (modern New Mexico), and Tejas (modern Texas). Today it is home of a large population of Native Americans, Hispanos, descendants of the American frontier, Asian Americans, and immigrants from Mexico and Latin America. California, New Mexico, and Texas continue to hold their unique identities which is reflected in their distinct regional cuisines, the multiple cuisines of California, New Mexican cuisine, Texan cuisine, and Tex-Mex. Spanish is a commonly spoken secondary language here; the state of New Mexico has its own distinct dialect. With the exception of Southern California, the signature meat is beef, since this is one of the two regions in which cowboys lived and modern cattle ranchers still eke out their living today. High-quality beefstock is a feature that has been present in the region for more than 200 years and the many cuts of beef are unique to the United States. These cuts of meat are different from the related Mexican cuisine over the border in that certain kind of offal, like lengua (tongue) cabeza (head) and tripas (tripe) are considered less desirable and are thus less emphasized. Typical cuts would include the ribs, brisket, sirloin, flank steak, skirt steak, and t-bone. Historically, Spanish settlers that came to the region found it completely unsuitable to the mining operations that much older settlements in Mexico had to offer as their technology was not advanced enough to extract the silver that would later be found. They had no knowledge of the gold in California, which would not be found until 1848, and knew even less about the silver in Nevada, undiscovered until after the Civil War. Instead, in order to make the pueblos prosper, they adapted the old rancho system of places like Andalusia in Spain and brought the earliest beefstock, among these were breeds that would go feral and become the Texas longhorn, and Navajo-Churro sheep, still used as breeding stock because they are easy to keep and well adapted to the extremely arid and hot climate, where temperatures easily exceed 38 °C. Later, cowboys learned from their management practices, many of which still stand today, like the practical management of stock on horseback using the Western saddle. Likewise, settlers learned the cooking methods of those who came before and local tribes as well, for example, portions of Arizona and New Mexico still use the aforementioned beehive shaped clay contraption called an horno, an outdoor wood-fired oven both Native American tribes like the Navajo and Spaniards used for roasting meat, maize, and baking bread. Meats that see frequent use are elk meat, a favorite in crown roasts and burgers, and nearer the Mexican border rattlesnake, often skinned and stewed. The taste for alcohol tends toward light and clean flavors found in tequila, a staple of this region since the days of the Wild West and a staple in the bartender's arsenal for cocktails, especially in Las Vegas. In Utah, a state heavily populated by Mormons, alcohol is frowned upon by the Church of Jesus Christ of Latter-day Saints but still available in area bars in Salt Lake City, mainly consumed by the populations of Catholics and other Protestant denominations living there. Introduction of agriculture was limited prior to the 20th century and the development of better irrigation techniques, but included the addition of peaches, a crop still celebrated by Native American tribes like the Havasupai, and oranges. Today in Arizona, Texas, and New Mexico the favored orange today is the Moro blood orange, which often finds its way into the local cuisine, like cakes and marmalade. Pine nuts are a particular regional specialty and feature often in fine dining and cookies; in Nevada the Native American tribes that live there are by treaty given rights to exclusive harvest, and in New Mexico they reserve usage of the term piñon for certain species of indigenous pine nuts. From Native Americans, Westerners learned the practice of eating cactus fruit from the myriad species of opuntia that occupy the Chihuahuan, Sonoran, and Mojave desert lands. In California, Spanish missionaries brought with them the mission fig, and today this fruit is a delicacy. Cuisine in this region tends to have certain key ingredients: tomatoes, onions, black beans, pinto beans, rice, bell peppers, chile peppers, and cheese, in particular Monterey Jack, invented in Southern California in the 19th century and itself often further altered into pepper Jack where spicy jalapeño peppers are incorporated into the cheese to create a smoky taste. Chili peppers play an important role in the cuisine, with a few native to the region. This is especially true with the region's distinct New Mexico chile pepper, still grown by Hispanos of New Mexico and Puebloans the most sought after of which come from the Hatch valley, Albuquerque's Central Rio Grande, Chimayo, and Pueblos. In New Mexico, chile is eaten on a variety of foods, such as the green chile cheeseburger, made popular by fast food chains such as Blake's Lotaburger. Indeed, even national fast food chains operating in the state, such as McDonald's, offer locally grown chile on many of their menu items. In the 20th century a few more recent additions have arrived like the poblano pepper, rocoto pepper, ghost pepper, thai chili pepper, and Korean pepper, the last three especially when discussing Southern California and its large population from East and South Asia. Cornbread is consumed, however the recipe differs from ones in the East in that the batter is cooked in a cast-iron skillet. Outdoor cooking is popular and still utilizes an old method settlers brought from the East with them, in which a cast-iron Dutch oven is covered with the coals of the fire and stacked or hung from a tripod: this is different from the earthenware pots of Mexico. Tortillas are still made the traditional way here and form an important component of the spicy breakfast burrito, which contains ham, eggs, and salsa or pico de gallo. They are also used for regular burritos, which contains any combination of marinated meats, vegetables, and piquant chilis; smothered burritos, often both containing and topped with New Mexico chile sauces; quesadillas, a much loved grilled dish where cheese and other ingredients are stuffed between two tortillas and served by the slice; and steak fajitas, where sliced skirt steak sizzles in a skillet with caramelized onions. Unlike Mexico, tortillas of this region also may incorporate vegetables like spinach into the flatbread dough to make wraps, which were invented in Southern California. Food here tends to use pungent spices and condiments, typically chili verde sauce, various kinds of hot sauce, sriracha sauce, chili powder, cayenne pepper, white pepper, cumin, paprika, onion powder, thyme and black pepper. Nowhere is this fiery mix of spice more evident than in the dishes chili con carne, a meaty stew, and cowboy beans, both of which are a feature of regional cookoffs. Southern California has several additions like five spice powder, rosemary, curry powder, kimchi, and lemongrass, with many of these brought by recent immigration to the region and often a feature of Southern California's fusion cuisine, popular in fine dining. In Texas, the local barbecue is often entirely made up of beef brisket or large rib racks, where the meat is seasoned with a spice rub and cooked over coals of mesquite. In other portions of the state they smoke the meat and peppery sausages over high heat using pecan, apple, and oak wood and serve it with a side of pickled vegetables, a legacy of German and Czech settlers of the late 1800s. California is home to Santa Maria–style barbecue, where the spices involved generally are black pepper, paprika, and garlic salt, and grill over the coals of coast live oak. Native American additions may include Navajo frybread and corn on the cob, often roasted on the grill in its husk. A typical accompaniment or appetizer of all these states is the tortilla chip, which sometimes includes cornmeal from cultivars of corn that are blue or red in addition to the standard yellow of sweetcorn, and is served with salsa of varying hotness. Tortilla chips also are an ingredient in the Tex Mex dish nachos, where these chips are loaded with any combination of ground beef, melted Monterey Jack, cheddar, or Colby cheese, guacamole, sour cream, and salsa, and Texas usually prefers a version of potato salad as a side dish. For alcohol, a key ingredient is tequila: this spirit has been made on both sides of the US-Mexican border for generations, and in modern cuisine it is a must-have in a bartender's arsenal as well as an addition to dishes for sauteeing. Southern California is focused more towards the coast and has had more contact with immigration from the West Pacific and Baja California, in addition to having the international city of Los Angeles as its capital. Here, the prime mode of transportation is by car. Drive through fast food was invented in this area, but so was the concept of the gourmet burger movement, giving birth to chains like In-N-Out Burger, with many variations of burgers including chili, multiple patties, avocado, special sauces, and Angus or wagyu beef. Common accompaniments include thick milkshakes in various flavors like mint, chocolate, peanut butter, vanilla, strawberry, and mango. Smoothies are a common breakfast item made with fresh fruit juice, yogurt, and crushed ice. Agua fresca, a drink originated by Mexican immigrants, is a common hot-weather beverage sold in many supermarkets and at mom and pop stands, available in citrus, watermelon, and strawberry flavors; the California version usually served chilled without grain in it. The weather in Southern California is such that the temperature rarely drops below in winter, thus, sun-loving crops like pistachios, kiwifruit, avocadoes, strawberries, and tomatoes are staple crops of the region, the last often dried in the sun and a feature of salads and sandwiches. Olive oil is a staple cooking oil of the region and has been since the days of Junípero Serra; today the mission olive is a common tree growing in a Southern Californian's back garden. As a crop olives are increasingly a signature of the region along with Valencia oranges and Meyer lemons. Soybeans, bok choy, Japanese persimmon, thai basil, Napa cabbage, nori, mandarin oranges, water chestnuts, and mung beans are other crops brought to the region from East Asia and are common additions to salads as the emphasis on fresh produce in both Southern and Northern California is strong. Other vegetables and herbs have a distinct Mediterranean flavor which would include oregano, basil, summer squash, eggplant, and broccoli, with all of the above extensively available at farmers' markets all around Southern California. Naturally, salads native to Southern California tend to be hearty affairs, like Cobb salad and Chinese chicken salad, and dressings like green goddess and ranch are a staple. California-style pizza tends to have disparate ingredients with an emphasis on vegetables, with any combination of chili oil, prawns, eggs, chicken, shiitake mushrooms, olives, bell pepper, goat cheese, and feta cheese. Peanut noodles tend to include a sweet dressing with lo mein noodles and chopped peanuts. Fresh fish and shellfish in Southern California tends to be expensive in restaurants, but every year since the end of WWII, the Pismo clam festival has taken place where the local population takes a large species of clam and bakes, stuffs, and roasts it as it is a regional delicacy. Fishing for pacific species of octopus and the Humboldt squid are common, and both are a feature of East Asian and other L.A. fish markets. Lingcod is a coveted regional fish that is often caught in the autumn off the coast of San Diego and in the Channel Islands and often served baked. California sheephead are often grilled and are much sought after by spear fishermen and the immigrant Chinese population, in which case it is basket steamed. Most revered of all in recent years is the California spiny lobster, a beast that can grow to 44 lb, and is a delicacy that now rivals the fishery for Dungeness crab in its importance. Pacific and Hawaiian cuisine Hawaii is often considered to be one of the most culturally diverse U.S. states, as well as being the only state with an Asian-majority population and one of the few places where United States territory extends into the tropics. As a result, Hawaiian cuisine borrows elements of a variety of cuisines, particularly those of Asian and Pacific-rim cultures, as well as traditional native Hawaiian and a few additions from the American mainland. American influence in the last 150 years has brought cattle, goats, and sheep to the islands, introducing cheese, butter, and yogurt products, as well as crops like red cabbage. Major Asian and Polynesian influences on modern Hawaiian cuisine are from Japan, Korea, Vietnam, China (especially near the Pearl River delta,) Samoa, and the Philippines. From Japan, the concept of serving raw fish as a meal with rice was introduced, as was soft tofu, setting the stage for the popular dish called poke. From Korea, immigrants to Hawaii brought a love of spicy garlic marinades for meat and kimchi. From China, their version of char siu baau became modern manapua, a type of steamed pork bun with a spicy filling. Filipinos brought vinegar, bagoong, and lumpia, and during the 20th century immigrants from American Samoa brought the open pit fire umu and the Vietnamese introduced lemongrass and fish sauce. Each East Asian culture brought several different kinds of noodles, including udon, ramen, mei fun, and pho, and today these are common lunchtime meals. Much of this cuisine mixes and melts into traditions like the lu'au, whose traditional elaborate fare was once the prerogative of kings and queens but is today the subject of parties for both tourists and also private parties for the ‘ohana (meaning family and close friends.) Traditionally, women and men ate separately under the Hawaiian kapu system, a system of religious beliefs that honored the Hawaiian gods similar to the Maori tapu system, though in this case had some specific prohibitions towards females eating things like coconut, pork, turtle meat, and bananas as these were considered parts of the male gods. Punishment for violation could be severe, as a woman might endanger a man's mana, or soul, by eating with him or otherwise by eating the forbidden food because doing so dishonored the male gods. As the system broke down after 1810, introductions of foods from laborers on plantations began to be included at feasts and much cross pollination occurred, where Asian foodstuffs mixed with Polynesian foodstuffs like breadfruit, kukui nuts, and purple sweet potatoes. Some notable Hawaiian fare includes seared ahi tuna, opakapaka (snapper) with passionfruit, Hawaiian island-raised lamb, beef and meat products, Hawaiian plate lunch, and Molokai shrimp. Seafood traditionally is caught fresh in Hawaiian waters, and particular delicacies are ula poni, papaikualoa, ‘opihi, and ‘opihi malihini, better known as Hawaiian spiny lobster, Kona crab, Hawaiian limpet, and abalone, the last brought over with Japanese immigrants. Some cuisine also incorporates a broad variety of produce and locally grown agricultural products, including tomatoes, sweet Maui onions, taro, and macadamia nuts. Tropical fruits also play an important role in the cuisine as a flavoring in cocktails and in desserts, including local cultivars of bananas, sweetsop, mangoes, lychee, coconuts, papayas, and lilikoi (passionfruit). Pineapples have been an island staple since the 19th century and figure into many marinades and drinks. Common dishes found on a regional level Ethnicity-specific and immigrant influence The influence of ethnicity-specific cuisines like Italian cuisine and Mexican cuisine was present in the United States by World War I. There are recipes for Chilean meat pies, chicken chop suey, chow mein, Mexican pork pastries and Italian meatballs going back to at least the 1930s, but many of the recipes were Anglicized and they appeared relatively infrequently compared to Northern European recipes. 19th-century cookbooks bear evidence of diverse influences with some including recipes like Indian pickle, Italian pork and various curries. 19th-century literature shows knowledge of Jewish, Russian, Italian, Chinese and Greek-American cuisines, and foreign cookbooks continued to grow more detailed through World War I including recipes like Peruvian chicken, Mexican enchiladas, Chilean corn pudding and Hindustan chicken curry. Louise Rice, author of Dainty Dishes from Foreign Lands describes the recipes in her book as "not wholly vegetarian" though noting at the time of publication in 1911 that most of the recipes would likely be new to average American cooks and likely contain higher proportions of vegetables to meat. She includes Italian pasta recipes like macaroni in milk, soups and polentas and German recipes like liver dumplings called Leberknödel and a variation of Sauerbraten. The demand for ethnic foods in the United States reflects the nation's changing diversity as well as its development over time. According to the National Restaurant Association, Restaurant industry sales are expected to reach a record high of $476 billion in 2005, an increase of 4.9 percent over 2004... Driven by consumer demand, the ethnic food market reached record sales in 2002, and has emerged as the fastest growing category in the food and beverage product sector, according to USBX Advisory Services. Minorities in the U.S. spend a combined $142 billion on food and by 2010, America's ethnic population is expected to grow by 40 percent. A movement began during the 1980s among popular leading chefs to reclaim America's ethnic foods within its regional traditions, where these trends originated. One of the earliest was Paul Prudhomme, who in 1984 began the introduction of his influential cookbook, Paul Prodhomme's Louisiana Kitchen, by describing the over 200-year history of Creole and Cajun cooking; he aims to "preserve and expand the Louisiana tradition." Prodhomme's success quickly inspired other chefs. Norman Van Aken embraced a Floridian type cuisine fused with many ethnic and globalized elements in his Feast of Sunlight cookbook in 1988. California became swept up in the movement, then seemingly started to lead the trend itself, in, for example, the popular restaurant Chez Panisse in Berkeley. Examples of the Chez Panisse phenomenon, chefs who embraced a new globalized cuisine, were celebrity chefs like Jeremiah Tower and Wolfgang Puck, both former colleagues at the restaurant. Puck went on to describe his belief in contemporary, new style American cuisine in the introduction to The Wolfgang Puck Cookbook: Another major breakthrough, whose originators were once thought to be crazy, is the mixing of ethnic cuisines. It is not at all uncommon to find raw fish listed next to tortillas on the same menu. Ethnic crossovers also occur when distinct elements meet in a single recipe. This country is, after all, a huge melting pot. Why should its cooking not illustrate the American transformation of diversity into unity? Puck's former colleague, Jeremiah Tower became synonymous with California Cuisine and the overall American culinary revolution. Meanwhile, the restaurant that inspired both Puck and Tower became a distinguished establishment, popularizing its so called "mantra" in its book by Paul Bertolli and owner Alice Waters, Chez Panisse Cooking, in 1988. Published well after the restaurants' founding in 1971, this new cookbook from the restaurant seemed to perfect the idea and philosophy that had developed over the years. The book embraced America's natural bounty, specifically that of California, while containing recipes that reflected Bertoli and Waters' appreciation of both northern Italian and French style foods. Early ethnic influences While the earliest cuisine of the United States was influenced by Native Americans, the thirteen colonies, or the antebellum South, the overall culture of the nation, its gastronomy and the growing culinary arts became ever more influenced by its changing ethnic mix and immigrant patterns from the 18th and 19th centuries unto the present. Some of the ethnic groups that continued to influence the cuisine were here in prior years; others arrived more numerously during "The Great Transatlantic Migration" (of 1870–1914) or other mass migrations. Some of the ethnic influences could be found across the nation after the American Civil War and into the continental expansion for most of the 19th century. Ethnic influences already in the nation at that time would include the following groups and their respective cuisines: Select nationalities of Europe and the respective developments from early modern European cuisine of the colonial age: British-Americans and on-going developments in New England cuisine, the national traditions founded in the cuisine of the original thirteen colonies, The Cuisine of the Southern United States, and many aspects of other regional cuisine. Spanish Americans and early modern Spanish cuisine, as well as Basque-Americans and Basque cuisine. Early German-American or Pennsylvania Dutch and Pennsylvania Dutch cuisine French Americans and their New World regional identities such as: Acadian Cajun and Cajun cuisine Louisiana Creole and Louisiana Creole cuisine. Louisiana Creole (also called French Créole) refers to native-born people of the New Orleans area who are descended from the Colonial French and Spanish settlers of Colonial French Louisiana, before it became part of the United States in 1803 with the Louisiana Purchase. The various ethnicities originating from the early gastronomy and cuisines of the New World, Latin American cuisine, and North American cuisine: Native Americans in the United States and Native American cuisine African Americans and Soul food. Puerto Rican cuisine Mexican Americans and Mexican-American cuisine; as well as related regional cuisines: Tex-Mex (regional Texas and Mexican fusion) Some aspects of "Southwestern cuisine". New Mexican cuisine from New Mexico and the historical region of Santa Fe de Nuevo México, and now ethnically tied to the Pueblos and Hispanos of New Mexico. Later ethnic and immigrant influence Mass migrations of immigrants to the United States came over time. Historians identify several waves of migration to the United States: one from 1815 to 1860, in which some five million English, Irish, German, Scandinavian, and others from northwestern Europe came to the United States; one from 1865 to 1890, in which some 10 million immigrants, also mainly from northwestern Europe, settled; and a third from 1890 to 1914, in which 15 million immigrants, mainly from central, eastern, and southern Europe (many Austrian, Hungarian, Turkish, Lithuanian, Russian, Jewish, Greek, Italian, and Romanian) settled in the United States. Together with earlier arrivals to the United States (including the indigenous Native Americans, Hispanic and Latino Americans, particularly in the West, Southwest, and Texas; African Americans who came to the United States in the Atlantic slave trade; and early colonial migrants from Europe), these new waves of immigrants had a profound impact on national or regional cuisine. Some of these more prominent groups include the following: Albanian Americans—Albanian cuisine Arab Americans, particularly Lebanese Americans (the largest ethnic Arab group in the United States)—Arab cuisine, Lebanese cuisine Argentine Americans—Argentine cuisine Armenian Americans—Armenian cuisine Brazilian Americans—Brazilian cuisine Cambodian Americans—Cambodian cuisine Chinese Americans—American Chinese cuisine, Chinese cuisine Colombian Americans—Colombian cuisine Cuban Americans—Cuban cuisine Dominican Americans—Dominican Republic cuisine Dutch Americans—Dutch cuisine Ethiopian Americans—Eritrean Americans: Ethiopian cuisine, Eritrean cuisine in Los Angeles, Washington, D.C., Denver, New York. Filipino Americans—Filipino cuisine, Filipino-American cuisine French Americans—French cuisine German Americans—German cuisine (the Pennsylvania Dutch, although descended from Germans, arrived earlier than the bulk of German migrants and have distinct culinary traditions) Greek Americans—Greek-American cuisine, Greek cuisine, Mediterranean cuisine Guatemalan Americans—Guatemalan cuisine Haitian Americans—Haitian cuisine Honduran Americans—Honduran cuisine Hungarian Americans—Hungarian cuisine Indian Americans—Indian cuisine Irish Americans—Irish cuisine Italian Americans—Italian-American cuisine, Italian cuisine Japanese Americans—Japanese cuisine, with influences on the Hawaiian cuisine Jewish Americans—Jewish cuisine, with particular influence on New York City cuisine Korean Americans—Korean cuisine Lithuanian Americans—Lithuanian cuisine, Midwest Nicaraguan American—Nicaraguan cuisine Nigerian Americans—Nigerian cuisine Pakistani Americans—Pakistani cuisine Peruvian Americans—Peruvian cuisine Polish Americans—Polish cuisine, with particular impact on Midwest Polynesian Americans—Hawaiian cuisine Portuguese Americans—Portuguese cuisine Romanian Americans—Romanian cuisine Russian Americans—Russian cuisine, with particular impact on Midwest Salvadoran Americans—Salvadoran cuisine Scottish Americans—Scottish cuisine Spanish Americans—Spanish cuisine Thai Americans—Thai cuisine Turkish Americans—Turkish cuisine, Balkan cuisine Venezuelan Americans—Venezuelan cuisine Vietnamese Americans—Vietnamese cuisine West Indian Americans—Caribbean cuisine, Jamaican cuisine, Trinidad and Tobago cuisine, Barbadian cuisine, Bahamian cuisine Italian, Mexican and Chinese (Cantonese) cuisines have indeed joined the mainstream. These three cuisines have become so ingrained in the American culture that they are no longer foreign to the American palate. According to the study, more than nine out of 10 consumers are familiar with and have tried these foods, and about half report eating them frequently. The research also indicates that Italian, Mexican and Chinese (Cantonese) have become so adapted to such an extent that "authenticity" is no longer a concern to customers. Contributions from these ethnic foods have become as common as traditional "American" fares such as hot dogs, hamburgers, beef steak, which are derived from German cuisine, (chicken-fried steak, for example, is a variation on German schnitzel), cherry pie, Coca-Cola, milkshakes, fried chicken (Fried chicken is of English, Scottish, and African influence), Pepsi, Dr Pepper and so on. Nowadays, Americans also have a ubiquitous consumption of foods like pizza and pasta, tacos and burritos to "General Tso's chicken" and fortune cookies. Fascination with these and other ethnic foods may also vary with region. Other popular foods Fast food The United States has a large fast food industry. Major American fast food chains include McDonald's, Burger King, Wendy's, Domino's, Pizza Hut, KFC, Popeyes, Subway, Taco Bell, Arby's, Starbucks, Dunkin' Donuts, White Castle, In-N-Out Burger, Sonic Drive-In, Chick-fil-A, Church's Chicken, and Raising Cane's, among numerous other multinational, national, regional, and local chains. Traditional American fast food items are hamburgers, french fries, breaded chicken, and pizza, though several chains also offer items from different cuisines modified for American palates, such as tacos, pasta, and stir-fry. Many American fast food chains have expanded abroad to other countries, typically offering standard American fare alongside items adapted to appeal to regional tastes within their markets. Desserts A classic American dessert is apple pie. Some other famous American desserts are banana split, Boston cream pie, key lime pie, and bananas foster. Other famous American desserts are chocolate chip cookies, pecan pie, carrot cake, banana pudding, S'more, black and white cookies, pumpkin pie, coconut cake, funnel cake, brownies and red velvet cake. Influential figures and American cuisine on television American chefs have been influential both in the food industry and in popular culture. Some important 19th-century American chefs include Charles Ranhofer of Delmonico's Restaurant in New York, and Bob Payton, who is credited with bringing American-style pizza to the UK. Later, chefs Charles Scotto, Louis Pacquet, John Massironi were founded the American Culinary Federation in 1930, taking after similar organizations across Europe. In the 1940s, Chef James Beard hosted the first nationally televised cooking show I Love to Eat. His name is also carried by the foundation and prestigious cooking award recognizing excellence in the American cooking community. Since Beard, many chefs and cooking personalities have taken to television, and the success of the Cooking Channel and Food Network have contributed to the popularity of American cuisine. In 1946, the Culinary Institute of America was founded by Katharine Angel and Frances Roth. This would become the United States' most prestigious culinary school, where many of the most talented American chefs would study prior to successful careers. The American Culinary community has grown due to both restaurants and media, through the work of many talented chefs. Influential figures Notable American restaurant chefs include Samin Nosrat (Salt, Fat, Acid, Heat), Thomas Keller (The French Laundry), Charlie Trotter (Trotter's), Grant Achatz (Alinea), Alfred Portale (Portale), Paul Prudhomme (K-Paul's), Paul Bertolli (Oliveto), Jonathan Waxman (Barbuto), Mark Peel (Campanile), Frank Stitt (Bottega), Alice Waters (Chez Panisse), Wolfgang Puck (Spago), Patrick O'Connell (The Inn), Eric Ripert (Le Bernardin), Todd English (Olives) and Anthony Bourdain (Les Halles). Many of these chefs have received much critical acclaim, as Keller, Achatz, Ripert and O'Connell have all received three Michelin stars, the highest distinction which a restaurant can be given. Keller was given this award for The French Laundry, Achatz for Alinea, Ripert for Le Bernardin and O'Connell for The Inn at Little Washington. Celebrity chefs have also helped to expand the culinary arts into popular culture, with chefs such as David Chang (Chef's Table), Alton Brown (Iron Chef America), Emeril Lagasse (Emeril Live), Cat Cora (Iron Chef America), Erik Davidson (Phat Erik's), Michael Symon (The Chew), Bobby Flay (Beat Bobby Flay), Ina Garten (Barefoot Contessa) and Guy Fieri (Diners, Drive-ins and Dives). Many of these celebrity chefs, such as David Chang, Emeril Lagasse and Bobby Flay began their careers in restaurants before branching out into television. The shows have a wide variety of formats, including cooking competitions, such as Iron Chef, documentaries, such as Anthony Bourdain's Parts Unknown, shows that take a look into restaurants, as Chef's Table does, and shows that teach cooking. The success of food television specifically in the United States has helped American Cuisine grow around the world. Regional cuisine chefs Regional chefs are emerging as localized celebrity chefs with growing broader appeal, such as Peter Merriman (Hawaii Regional Cuisine), Roy Choi (Korean American Cuisine), Jerry Traunfeld, Alan Wong (Pacific Rim cuisine), Rick Bayless and Daniela Soto-Innes (traditional Mexican cuisine with modern interpretations), Norman Van Aken (New World Cuisine – fusion Latin, Caribbean, Asian, African and American), and Mark Miller (American Southwest cuisine).

Ahmad Shah Massoud (Dari/Pashto: , ; September 2, 1953September 9, 2001) was an Afghan politician and military commander. He was a powerful guerrilla commander during the resistance against the Soviet occupation between 1979 and 1989. In the 1990s, he led the government's military wing against rival militias; after the Taliban takeover, he was the leading opposition commander against their regime until his assassination in 2001. Massoud came from an ethnic Tajik, Sunni Muslim background in the Panjshir Valley of Northern Afghanistan. He began studying engineering at Polytechnical University of Kabul in the 1970s, where he became involved with religious anti-communist movements around Burhanuddin Rabbani, a leading Islamist. He participated in a failed uprising against Mohammed Daoud Khan's government. He later joined Rabbani's Jamiat-e Islami party. During the Soviet–Afghan War, his role as a powerful insurgent leader of the Afghan mujahideen earned him the nickname "Lion of Panjshir" () among his followers. Supported by Britain's MI6 and to a lesser extent by the U.S. Central Intelligence Agency (CIA), he successfully resisted the Soviets from taking the Panjshir Valley. In 1992, he signed the Peshawar Accord, a peace and power-sharing agreement, in the post-communist Islamic State of Afghanistan. He was appointed the Minister of Defense as well as the government's main military commander. His militia fought to defend Kabul against militias led by Gulbuddin Hekmatyar and other warlords who were bombing the city, as well as later against the Taliban, who laid siege to the capital in January 1995 after the city had seen fierce fighting with at least 60,000 civilians killed. Following the rise of the Taliban in 1996, Massoud, who rejected the Taliban's fundamentalist interpretation of Islam, returned to armed opposition until he was forced to flee to Kulob, Tajikistan, strategically destroying the Salang Tunnel on his way north. He became the military and political leader of the United Islamic Front for the Salvation of Afghanistan or Northern Alliance, which by 2000 controlled only between 5 and 10 percent of the country. In 2001 he visited Europe and urged European Parliament leaders to pressure Pakistan on its support for the Taliban. He also asked for humanitarian aid to combat the Afghan people's gruesome conditions under the Taliban. On September 9, 2001, Massoud was injured in a suicide bombing by two al-Qaeda assassins, ordered personally by the al-Qaeda leader Osama bin Laden himself; he lost his life while en route to a hospital across the border in Tajikistan. Two days later, the September 11 attacks occurred in the United States, which ultimately led to the North Atlantic Treaty Organization invading Afghanistan and allying with Massoud's forces. The Northern Alliance eventually won the two-month-long war in December 2001, removing the Taliban from power. Massoud has been described as one of the greatest guerrilla leaders of the 20th century and has been compared to Josip Broz Tito, Ho Chi Minh and Che Guevara. Massoud was posthumously named "National Hero" by the order of President Hamid Karzai after the Taliban were ousted from power. The date of Massoud's death, September 9, was observed as a national holiday known as "Massoud Day" until the Taliban takeover in August 2021. His followers call him Amer Sāhib-e Shahīd (), which translates to "(our) martyred commander". He has been posthumously honored by a plaque in France in 2021, and in the same year was awarded with the highest honor of Tajikistan. Early life Ahmad Shah Massoud was born in 1953 in the small village of Jangalak, Bazarak in the Panjshir Valley (now administered as part of the Panjshir Province), to a well-to-do family native to the Panjshir Valley. Massoud's name at birth was 'Ahmad Shah' after King Ahamad Shah Durrani, founder of the modern, unified state of Afghanistan, later taking the name 'Massoud' as a nom de guerre in 1974 when he joined the resistance movement against the forces of Daoud Khan. Massoud's father, Dost Mohammad, was a colonel in the Royal Afghan Army; his mother, Bibi Khorshaid has been described as a "modern-minded" woman who taught herself to read and write determined to educate her daughters no less than her sons. Moving along with his father's postings, the adolescent Massoud attended primary school in Afghanistan's western city of Herat before his father was dispatched to Kabul. There, Massoud was sent to the renowned Franco-Afghan Lycée Esteqlal (lit. Independence High School) where he attained his proficiency in French. Massoud's experience at Lycée would be formative and, as he would later remark, was the happiest period of his life. At Lycée his classes were taught by French and Afghan tutors educated in France and the students donned Western jackets, neckties, trousers, skirts, scarves, and stockings. Although his knowledge of the French language would earn him greater affinity among French journalists and politicians, later conservative Islamist opponents such as Gulbuddin Hekmatyar and the Taliban would derogatorily dub him "The Frenchmen" or "The Parisian" suggestive of his sympathies to Western culture. While at the Lycée, Massoud was described as an intellectually-gifted student, hard-working, religiously devout, and mature for his age with a particular interest in ethics, politics, universal justice. Friends and family recall an instance where Massoud, returning from school, came to the defense of a younger boy leaving the three bullies knocked-out on the pavement. More formatively, Massoud followed closely reports of the 1967 Six-Day War and the defiant statements of Arab leaders like Egyptian President Gamal Abdel Nasser. He later told researcher Peter DeNeufville that, at fourteen, the war left him determined to be a soldier and gave him a new regard for Pan-Islamism after hearing the stories told by Jordanian, Egyptian, and Syrian soldiers defending their homelands. Massoud refused repeated suggestions to apply for a scholarship to study in France expressing his desire to remain in Afghanistan and apply to the nation's military academy in Kabul. By protest of his father and eldest brother, Massoud enrolled at Kabul Polytechnic Institute, then Kabul University's newest and most prestigious addition founded, financed, and operated by the Soviet Union. Massoud studied engineering and architecture but never attempted to learn Russian. There he found interest in politics, political Islam, and anti-Communism which often put him and his pious peers at odds with communist-inspired students. 1975 rebellion in Panjshir In 1973, former Prime Minister Mohammed Daoud Khan was brought to power in a coup d'état backed by the People's Democratic Party of Afghanistan, and the Republic of Afghanistan was established. These developments gave rise to an Islamist movement opposed to the increasing communist and Soviet influence over Afghanistan. During that time, while studying at Kabul University, Massoud became involved with the Muslim Youth (Sazman-i Jawanan-i Musulman), the student branch of the Jamiat-e Islami (Islamic Society), whose chairman then was the professor Burhanuddin Rabbani. Kabul University was a center for political debate and activism during that time. Infuriated by the arrogance of his communist peers and Russian professors, a physical altercation between Massoud and his Russian professor led Massoud to walk out of the university, and shortly after, Kabul. Two days later, Massoud and a number of fellow militant students traveled to Pakistan where, goaded by another trainee of the Pakistani Inter-Services Intelligence (ISI), Gulbaddin Hekmatyar, Massoud agreed to take part in a coup against Daoud with his forces rising up in the Panjshir and Hekmatyar's elsewhere. In July 1975, Massoud, with help from the Pakistani intelligence, led the first rebellion of Panjshir residents against the government of Daoud Khan. While the uprising in the Panjshir began saw initial success, even taking the military garrison in Rokha, the promised support from Kabul never came and the rebellion was suppressed by Daoud Khan's forces sending Massoud back into Pakistan (after a day hiding in Jangalak) where he would attend a secret, paramilitary ISI training center in Cherat. Dissatisfied, Massoud left the center and returned to Peshawar where he committed himself to personal military studies. Massoud read Mao Tse-tung's writings on the Long March, of Che Guevara's career, the memoirs of General de Gualle, General Võ Nguyên Giáp, Sun Tzu's Art of War, and an unnamed handbook on counterterrorism by an American general which Massoud called "the most instructive of all". After this failure, a "profound and long-lasting schism" within the Islamist movement began to emerge. The Islamic Society split between supporters of the more moderate forces around Massoud and Rabbani, who led the Jamiat-i Islami, and more radical Islamist elements surrounding Gulbuddin Hekmatyar, who founded the Hezb-i Islami. The conflict reached such a point that Hekmatyar reportedly tried to kill Massoud, then 22 years old. Resistance against communism Resistance against the PDPA (1978) The government of Mohammed Daoud Khan tried to scale back the communist People's Democratic Party of Afghanistan's influence, dismissing PDPA members from their government posts, appointing conservatives to replace them, and finally dissolved the PDPA, with the arrests of senior party members. On April 27, 1978, the PDPA and military units loyal to it killed Daoud Khan, his immediate family, and bodyguards in a violent coup, and seized control of the capital Kabul declaring the new Democratic Republic of Afghanistan (DRA). The new communist government, led by a revolutionary council, did not enjoy the support of the masses. It implemented a doctrine hostile to political dissent, whether inside or outside the party. The PDPA started reforms along Marxist–Leninist and Soviet lines. The reforms and the PDPA's affinity to the Soviet Union were met with strong resistance by the population, especially as the government attempted to enforce its Marxist policies by arresting or executing those who resisted. Between 50,000 and 100,000 people were estimated to have been arrested and killed by communist troops in the countryside alone. Due to the repression, large parts of the country, especially the rural areas, organized into open revolt against the PDPA government. By spring 1979, unrest had reached 24 out of 28 Afghan provinces, including major urban areas. Over half of the Afghan army either deserted or joined the insurrection. With religious elders declaring a jihad against the government, in May 1979 Massoud prepared in Peshawar to oppose the new communist government in Panjshir. Along with twenty-four of his friends, Massoud took a bus to Bajaur and, with arms-smuggling Pashtun tribesmen, marched on foot into the Panjshir Valley. Massoud's group seized control over a number of government outposts in the Valley, entered the Shomali Plain to capture Gulbahar, and cut off the Salang Highway, the main supply route between Kabul and the Soviet border raising alarm in both Kabul and Moscow which brought upon Massoud and his group a government counterattack. Believing that an uprising against the Soviet-backed communists would be supported by the people, Massoud, on July 6, 1979, started an insurrection in the Panjshir, which initially failed. Massoud decided to avoid conventional confrontation with the larger government forces and to wage a guerrilla war. He subsequently took full control of Panjshir, pushing out Afghan communist troops. Oliver Roy writes that in the following period, Massoud's "personal prestige and the efficiency of his military organization persuaded many local commanders to come and learn from him." Resistance against the Soviet Union (1979–1989) Following the 1979 Soviet invasion and occupation of Afghanistan, Massoud devised a strategic plan for expelling the invaders and overthrowing the communist regime. The first task was to establish a popularly based resistance force that had the loyalty of the people. The second phase was "active defense" of the Panjshir stronghold, while carrying out asymmetric warfare. In the third phase, the "strategic offensive", Massoud's forces would gain control of large parts of Northern Afghanistan. The fourth phase was the "general application" of Massoud's principles to the whole country, and the defeat of the Afghan communist government. Massoud's mujahideen attacked the occupying Soviet forces, ambushing Soviet and Afghan communist convoys travelling through the Salang Pass, and causing fuel shortages in Kabul. The Soviets mounted a series of offensives against the Panjshir. Between 1980 and 1985, these offensives were conducted twice a year. Despite engaging more men and hardware on each occasion, the Soviets were unable to defeat Massoud's forces. In 1982, the Soviets began deploying major combat units in the Panjshir, numbering up to 30,000 men. Massoud pulled his troops back into subsidiary valleys, where they occupied fortified positions. When the Soviet columns advanced onto these positions, they fell into ambushes. When the Soviets withdrew, Afghan army garrisons took over their positions. Massoud and his mujahideen forces attacked and recaptured them one by one. In 1983, the Soviets offered Massoud a temporary truce, which he accepted in order to rebuild his own forces and give the civilian population a break from Soviet attacks. He put the respite to good use. In this time he created the Shura-e Nazar (Supervisory Council), which subsequently united 130 commanders from 12 Afghan provinces in their fight against the Soviet army. This council existed outside the Peshawar parties, which were prone to internecine rivalry and bickering, and served to smooth out differences between resistance groups, due to political and ethnic divisions. It was the predecessor of what could have become a unified Islamic Afghan army. Relations with the party headquarters in Peshawar were often strained, as Rabbani insisted on giving Massoud no more weapons and supplies than to other Jamiat commanders, even those who did little fighting. To compensate for this deficiency, Massoud relied on revenues drawn from exports of emeralds and lapis lazuli, that are traditionally exploited in Northern Afghanistan. Regarding infighting among different mujahideen factions, following a Soviet truce, Massoud said in an interview: Britain's MI6 having activated long-established networks of contacts in Pakistan were able to support Massoud, and soon became their key ally. MI6 sent an annual mission of two of their officers as well as military instructors to Massoud and his fighters. They also gave supplies to Massoud which included sniper rifles with silencers and mortars. As well as training Massoud's junior commanders, MI6 team's most important contribution was help with organisation and communication via radio equipment which was highly useful for Massoud to coordinate his forces and be warned of any impending Soviet attacks. The United States however provided Massoud with comparatively less support than other factions. Part of the reason was that it permitted its funding and arms distribution to be administered by Pakistan, which favored the rival mujahideen leader Gulbuddin Hekmatyar. In an interview, Massoud said, "We thought the CIA knew everything. But they didn't. They supported some bad people [meaning Hekmatyar]." Primary advocates for supporting Massoud were the US State Department's Edmund McWilliams and Peter Tomsen, who were on the ground in Afghanistan and Pakistan. Others included two Heritage Foundation foreign policy analysts, Michael Johns and James A. Phillips, both of whom championed Massoud as the Afghan resistance leader most worthy of U.S. support under the Reagan Doctrine. Thousands of foreign Islamic volunteers entered Afghanistan to fight with the mujahideen against the Soviet troops. To organize support for the mujahideen, Massoud established an administrative system that enforced law and order (nazm) in areas under his control. The Panjshir was divided into 22 bases (qarargah) governed by a military commander and a civilian administrator, and each had a judge, a prosecutor and a public defender. Massoud's policies were implemented by different committees: an economic committee was charged with funding the war effort. The health committee provided health services, assisted by volunteers from foreign humanitarian non-governmental organizations, such as Aide médicale internationale. An education committee was charged with the training of the military and administrative cadre. A culture committee and a judiciary committee were also created. This expansion prompted Babrak Karmal to demand that the Red Army resume their offensives, in order to crush the Panjshir groups. However, Massoud had received warning of the attack through Britain's GCHQ intelligence and he evacuated all 130,000 inhabitants from the valley into the Hindukush mountains, leaving the Soviet bombings to fall on empty ground and the Soviet battalions to face the mountains. With the defeat of the Soviet-Afghan attacks, Massoud carried out the next phase of his strategic plan, expanding the resistance movement and liberating the northern provinces of Afghanistan. In August 1986, he captured Farkhar in Takhar Province. In November 1986, his forces overran the headquarters of the government's 20th division at Nahrin in Baghlan Province, scoring an important victory for the resistance. This expansion was also carried out through diplomatic means, as more mujahideen commanders were persuaded to adopt the Panjshir military system. Despite almost constant attacks by the Red Army and the Afghan army, Massoud increased his military strength. Starting in 1980 with a force of less than 1,000 ill-equipped guerrillas, the Panjshir valley mujahideen grew to a 5,000-strong force by 1984. After expanding his influence outside the valley, Massoud increased his resistance forces to 13,000 fighters by 1989. The junior commanders were trained by Britain's SAS as well as private military contractors, some being sent as far as Oman and even SAS training grounds in the Scottish Highlands. These forces were divided into different types of units: the locals (mahalli) were tasked with static defense of villages and fortified positions. The best of the mahalli were formed into units called grup-i zarbati (shock troops), semi-mobile groups that acted as reserve forces for the defense of several strongholds. A different type of unit was the mobile group (grup-i-mutaharek), a lightly equipped commando-like formation numbering 33 men, whose mission was to carry out hit-and-run attacks outside the Panjshir, sometimes as far as 100 km from their base. These men were professional soldiers, well-paid and trained, and, from 1983 on, they provided an effective strike force against government outposts. Uniquely among the mujahideen, these groups wore uniforms, and their use of the pakul made this headwear emblematic of the Afghan resistance. Massoud's military organization was an effective compromise between the traditional Afghan method of warfare and the modern principles of guerrilla warfare which he had learned from the works of Mao Zedong and Che Guevara. His forces were considered the most effective of all the various Afghan resistance movements. The Soviet army and the Afghan communist army were mainly defeated by Massoud and his mujahideen in numerous small engagements between 1984 and 1988. After describing the Soviet Union's military engagement in Afghanistan as "a bleeding wound" in 1986, Soviet General Secretary Mikhail Gorbachev began a withdrawal of Soviet troops from the nation in May 1988. On February 15, 1989, in what was depicted as an improbable victory for the mujahideen, the last Soviet soldier left the nation. Fall of the Afghan communist regime (1992) After the departure of Soviet troops in 1989, the People's Democratic Party of Afghanistan regime, then headed by Mohammad Najibullah, held its own against the mujahideen. Backed by a massive influx of weapons from the Soviet Union, the Afghan armed forces reached a level of performance they had never reached under direct Soviet tutelage. They maintained control over all of Afghanistan's major cities. During late 1990, helped by hundreds of mujahideen forces, Massoud targeted the Tajik Supreme Soviet, trying to oust communism from the neighboring Tajikistan to further destabilize the dying Soviet Union, which would also impact the Afghan government. At that time, as per Asad Durrani, the director-general of the ISI during this period, Massoud's base camp was in Garam Chashma, in Pakistan. By 1992, after the collapse of the Soviet Union, the Afghan regime eventually began to crumble. Food and fuel shortages undermined the capacities of the government's army, and a resurgence of factionalism split the regime between Khalq and Parcham supporters. A few days after Najibullah had lost control of the nation, his army commanders and governors arranged to turn over authority to resistance commanders and local warlords throughout the country. Joint councils (shuras) were immediately established for local government, in which civil and military officials of the former government were usually included. In many cases, prior arrangements for transferring regional and local authority had been made between foes. Collusions between military leaders quickly brought down the Kabul government. In mid-January 1992, within three weeks of the demise of the Soviet Union, Massoud was aware of conflict within the government's northern command. General Abdul Momim, in charge of the Hairatan border crossing at the northern end of Kabul's supply highway, and other non-Pashtun generals based in Mazar-i-Sharif, feared removal by Najibullah and replacement by Pashtun officers. When the generals rebelled, Abdul Rashid Dostum, who held general rank as head of the Jowzjani militia, also based in Mazar-i-Sharif, took over. He and Massoud reached a political agreement, together with another major militia leader, Sayyed Mansour, of the Ismaili community based in Baghlan Province. These northern allies consolidated their position in Mazar-i-Sharif on March 21. Their coalition covered nine provinces in the north and northeast. As turmoil developed within the government in Kabul, no government force stood between the northern allies and the major air force base at Bagram, some seventy kilometers north of Kabul. By mid-April 1992, the Afghan air force command at Bagram had capitulated to Massoud. On March 18, 1992, Najibullah decided to resign. On April 17, as his government fell, he tried to escape but was stopped at Kabul Airport by Dostum's forces. He took refuge at the United Nations mission, where he remained unharmed until 1996, while Massoud controlled the area surrounding the mission. Senior communist generals and officials of the Najibullah administration acted as a transitional authority to transfer power to Ahmad Shah Massoud's alliance. The Kabul interim authority invited Massoud to enter Kabul as the new Head of State, but he held back. Massoud ordered his forces, positioned to the north of Kabul, not to enter the capital until a political solution was in place. He called on all the senior Afghan party leaders, many then based in exile in Peshawar, to work out a political settlement acceptable to all sides and parties. War in Afghanistan (1992–2001) War in Kabul and other parts of the country (1992–1996) Peace and power-sharing agreement (1992) With United Nations support, most Afghan political parties decided to appoint a legitimate national government to succeed communist rule, through an elite settlement. While the external Afghan party leaders were residing in Peshawar, the military situation around Kabul involving the internal commanders was tense. A 1991 UN peace process brought about some negotiations, but the attempted elite settlement did not develop. In April 1992, resistance leaders in Peshawar tried to negotiate a settlement. Massoud supported the Peshawar process of establishing a broad coalition government inclusive of all resistance parties, but Hekmatyar sought to become the sole ruler of Afghanistan, stating, "In our country coalition government is impossible because, this way or another, it is going to be weak and incapable of stabilizing the situation in Afghanistan." Massoud wrote: All the parties had participated in the war, in jihad in Afghanistan, so they had to have their share in the government, and in the formation of the government. Afghanistan is made up of different nationalities. We were worried about a national conflict between different tribes and different nationalities. In order to give everybody their own rights and also to avoid bloodshed in Kabul, we left the word to the parties so they should decide about the country as a whole. We talked about it for a temporary stage and then after that the ground should be prepared for a general election. A recorded radio communication between the two leaders showed the divide as Massoud asked Hekmatyar: The Kabul regime is ready to surrender, so instead of the fighting we should gather. ... The leaders are meeting in Peshawar. ... The troops should not enter Kabul, they should enter later on as part of the government. Hekmatyar's response: We will march into Kabul with our naked sword. No one can stop us. ... Why should we meet the leaders?" Massoud answered: "It seems to me that you don't want to join the leaders in Peshawar nor stop your threat, and you are planning to enter Kabul ... in that case I must defend the people. At that point Osama bin Laden, trying to mediate, urged Hekmatyar to "go back with your brothers" and to accept a compromise. Bin Laden reportedly "hated Ahmad Shah Massoud". Bin Laden was involved in ideological and personal disputes with Massoud and had sided with Gulbuddin Hekmatyar against Massoud in the inner-Afghan conflict since the late 1980s. But Hekmatyar refused to accept a compromise, confident that he would be able to gain sole power in Afghanistan. On April 24, 1992, the leaders in Peshawar agreed on and signed the Peshawar Accord, establishing the post-communist Islamic State of Afghanistan – which was a stillborn 'state' with a paralyzed 'government' right from its inception, until its final succumbing in September 1996. The creation of the Islamic State was welcomed though by the General Assembly of the United Nations and the Islamic State of Afghanistan was recognized as the legitimate entity representing Afghanistan until June 2002, when its successor, the Islamic Republic of Afghanistan, was established under the interim government of Hamid Karzai. Under the 1992 Peshawar Accord, the Defense Ministry was given to Massoud while the Prime Ministership was given to Hekmatyar. Hekmatyar refused to sign. With the exception of Hekmatyar's Hezb-e Islami, all of the other Peshawar resistance parties were unified under this peace and power-sharing accord in April 1992. Escalating war over Kabul (1992) Although repeatedly offered the position of prime minister, Gulbuddin Hekmatyar refused to recognize the peace and power-sharing agreement. His Hezb-e Islami militia initiated a massive bombardment campaign against the Islamic State and the capital city Kabul. Gulbuddin Hekmatyar received operational, financial and military support from neighboring Pakistan. The Director of the Centre for Arab and Islamic Studies at the Australian National University, Amin Saikal, writes in Modern Afghanistan: A History of Struggle and Survival that without Pakistan's support, Hekmatyar "would not have been able to target and destroy half of Kabul." Saikal states that Pakistan wanted to install a favorable regime under Hekmatyar in Kabul so that it could use Afghan territory for access to Central Asia. Hekmatyar's rocket bombardments and the parallel escalation of violent conflict between two militias, Ittihad and Wahdat, which had entered some suburbs of Kabul, led to a breakdown in law and order. Shia Iran and Sunni Wahabbi Saudi Arabia, as competitors for regional hegemony, encouraged conflict between the Ittihad and Wahdat factions. On the one side was the Shia Hazara Hezb-i Wahdat of Abdul Ali Mazari and on the other side, the Sunni Pashtun Ittihad-i Islami of Abdul Rasul Sayyaf. According to Human Rights Watch, Iran was strongly supporting the Hezb-i Wahdat forces, with Iranian intelligence officials providing direct orders, while Saudi Arabia supported Sayyaf and his Ittihad-i Islami faction to maximize Wahhabi influence. Kabul descended into lawlessness and chaos, as described in reports by Human Rights Watch and the Afghanistan Justice Project. Massoud's Jamiat commanders, the interim government, and the International Committee of the Red Cross (ICRC) repeatedly tried to negotiate ceasefires, which broke down in only a few days. Another militia, the Junbish-i Milli of former communist general Abdul Rashid Dostum, was backed by Uzbekistan. Uzbek president Islam Karimov was keen to see Dostum controlling as much of Afghanistan as possible, especially in the north. Dostum repeatedly changed allegiances. The Afghanistan Justice Project (AJP) says, that "while [Hekmatyar's anti-government] Hizb-i Islami is frequently named as foremost among the factions responsible for the deaths and destruction in the bombardment of Kabul, it was not the only perpetrator of these violations." According to the AJP, "the scale of the bombardment and kinds of weapons used represented disproportionate use of force" in a capital city with primarily residential areas by all the factions involved – including the government forces. Crimes were committed by individuals within the different armed factions. Gulbuddin Hekmatyar released 10,000 dangerous criminals from the main prisons into the streets of Kabul to destabilize the city and cut off Kabul from water, food and energy supplies. The Iran-controlled Wahdat of Abdul Ali Mazari, as well as the Ittihad of Abdul Rasul Sayyaf supported by Saudi Arabia, targeted civilians of the 'opposite side' in systematic atrocities. Abdul Rashid Dostum allowed crimes as a perceived payment for his troops. Afshar operation (February 1993) "The major criticism of Massoud's human rights record" is the escalation of the Afshar military operation in 1993. A report by the Afghanistan Justice Project describes Massoud as failing to prevent atrocities carried out by his forces and those of their factional ally, Ittihad-i Islami, against civilians on taking the suburb of Afshar during a military operation against an anti-state militia allied to Gulbuddin Hekmatyar. They shelled residential areas in the capital city in February 1993. Critics said that Massoud should have foreseen these problems. A meeting convened by Massoud on the next day ordered a halt to killing and looting, but it failed to stop abuses. Human Rights Watch, in a report based largely on the material collected by the Afghanistan Justice Project, concurs that Massoud's Jamiat forces bear a share of the responsibility for human rights abuses throughout the war, including the indiscriminate targeting of civilians in Afshar, and that Massoud was personally implicated in some of these abuses. Roy Gutman has argued that the witness reports about Afshar cited in the AJP report implicated only the Ittihad forces, and that these had not been under Massoud's direct command. Anthony Davis, who studied and observed Massoud's forces from 1981 to 2001, reported that during the observed period, there was "no pattern of repeated killings of enemy civilians or military prisoners" by Massoud's forces. Edward Girardet, who covered Afghanistan for over three decades, was also in Kabul during the war. He states that while Massoud was able to control most of his commanders well during the anti-Soviet and anti-Taliban resistance, he was not able to control every commander in Kabul. According to this and similar testimonies, this was due to a breakdown of law and order in Kabul and a war on multiple fronts, which they say, Massoud personally had done all in his power to prevent: Further war over Kabul (March–December 1993) In 1993, Massoud created the Cooperative Mohammad Ghazali Culture Foundation (Bonyad-e Farhangi wa Ta'wani Mohammad-e Ghazali) to further humanitarian assistance and politically independent Afghan culture. The Ghazali Foundation provided free medical services during some days of the week to residents of Kabul who were unable to pay for medical treatment. The Ghazali Foundation's department for distribution of auxiliary goods was the first partner of the Red Cross. The Ghazali Foundation's department of family consultation was a free advisory board, which was accessible seven days a week for the indigent. Although Massoud was responsible for the financing of the foundation, he did not interfere with its cultural work. A council led the foundation and a jury, consisting of impartial university lecturers, decided on the works of artists. The Ghazali foundation enabled Afghan artists to exhibit their works at different places in Kabul, and numerous artists and authors were honoured for their works; some of them neither proponents of Massoud nor the Islamic State government. In March 1993, Massoud resigned his government position in exchange for peace, as requested by Hekmatyar, who considered him as a personal rival. According to the Islamabad Accord, Burhanuddin Rabbani, belonging to the same party as Massoud, remained president, while Gulbuddin Hekmatyar took the long-offered position of prime minister. Two days after the Islamabad Accord was put into effect, however, Hekmatyar's allies of Hezb-e Wahdat renewed rocket attacks in Kabul. Both the Wahhabi Pashtun Ittehad-i Islami of Abdul Rasul Sayyaf backed by Saudi Arabia and the Shia Hazara Hezb-e Wahdat supported by Iran remained involved in heavy fighting against each other. Hekmatyar was afraid to enter Kabul proper, and chaired only one cabinet meeting. The author Roy Gutman of the United States Institute of Peace wrote in How We Missed the Story: Osama bin Laden, the Taliban, and the Hijacking of Afghanistan: Hekmatyar had become prime minister ... But after chairing one cabinet meeting, Hekmatyar never returned to the capital, fearing, perhaps, a lynching by Kabulis infuriated over his role in destroying their city. Even his close aides were embarrassed. Hekmatyar spokesman Qutbuddin Helal was still setting up shop in the prime minister's palace when the city came under Hezb[-i Islami] rocket fire late that month. "We are here in Kabul and he is rocketing us. Now we have to leave. We can't do anything," he told Massoud aides. Hekmatyar, who was generally opposed to coalition government and struggled for undisputed power, had conflicts with other parties over the selection of cabinet members. His forces started major attacks against Kabul for one month. The President, Burhanuddin Rabbani, was attacked when he attempted to meet Hekmatyar. Massoud resumed his responsibilities as minister of defense. In May 1993, a new effort was made to reinstate the Islamabad Accord. In August, Massoud reached out to Hekmatyar in an attempt to broaden the government. By the end of 1993, however, Hekmatyar and the former communist general and militia leader, Abdul Rashid Dostum, were involved in secret negotiations encouraged by Pakistan's secret Inter-Services Intelligence, Iran's intelligence service, and Uzbekistan's Karimov administration. They planned a coup to oust the Rabbani administration and to attack Massoud in his northern areas. War in Kabul, Taliban arise in the south (1994) In January 1994, Hekmatyar and Dostum mounted a bombardment campaign against the capital and attacked Massoud's core areas in the northeast. Amin Saikal writes, Hekmatyar had the following objectives in all his operations: The first was to make sure that Rabbani and Massoud were not allowed to consolidate power, build a credible administration, or expand their territorial control, so that the country would remain divided into small fiefdoms, run by various Muajhideen leaders and local warlords or a council of such elements, with only some of them allied to Kabul. The second was to ensure the Rabbani government acquired no capacity to dispense patronage, and to dissuade the Kabul population from giving more than limited support to the government. The third was to make Kabul an unsafe city for representatives of the international community and to prevent the Rabbani government from attracting the international support needed to begin the post-war reconstruction of Afghanistan and generate a level of economic activity which would enhance its credibility and popularity. By mid-1994, Hekmatyar and Dostum were on the defensive in Kabul against Islamic State forces led by Massoud. Southern Afghanistan had been neither under the control of foreign-backed militias nor of the government in Kabul, but was ruled by local Pashtun leaders, such as Gul Agha Sherzai, and their militias. In 1994, the Taliban (a movement originating from Jamiat Ulema-e-Islam-run religious schools for Afghan refugees in Pakistan) also developed in Afghanistan as a politico-religious force, reportedly in opposition to the tyranny of the local governor. When the Taliban took control of Kandahar in 1994, they forced the surrender of dozens of local Pashtun leaders who had presided over a situation of complete lawlessness and atrocities. In 1994, the Taliban took power in several provinces in southern and central Afghanistan. Taliban siege of Kabul (1995–1996) Hizb-i Islami had bombarded Kabul from January 1994 until February 1995 when the Taliban expelled Hizb from its Charasiab headquarters, after which the Taliban relaunched the bombardment of Kabul and started to besiege the town. By early 1995, Massoud initiated a nationwide political process with the goal of national consolidation and democratic elections. He arranged a conference in three parts uniting political and cultural personalities, governors, commanders, clergymen and representatives, in order to reach a lasting agreement. Massoud's favourite for candidacy to the presidency was Dr. Mohammad Yusuf, the first democratic prime minister under Zahir Shah, the former king. In the first meeting representatives from 15 different Afghan provinces met, in the second meeting there were already 25 provinces participating. Massoud also invited the Taliban to join the peace process wanting them to be a partner in providing stability to Afghanistan during such a process. But the Taliban, which had emerged over the course of 1994 in southern Afghanistan, were already at the doors of the capital city. Against the advice of his security personnel, Massoud went to talk to some Taliban leaders in Maidan Shar, Taliban territory. The Taliban declined to join the peace process leading towards general elections. When Massoud returned to Kabul unharmed, the Taliban leader who had received him as his guest paid with his life: he was killed by other senior Taliban for failing to assassinate Massoud while the possibility had presented itself. The Taliban, placing Kabul under a two-year siege and bombardment campaign from early 1995 onwards, in later years committed massacres against civilians, compared by United Nations observers to those that happened during the War in Bosnia. Neighboring Pakistan exerted strong influence over the Taliban. A publication with the George Washington University describes: "Initially, the Pakistanis supported ... Gulbuddin Hekmatyar ... When Hekmatyar failed to deliver for Pakistan, the administration began to support a new movement of religious students known as the Taliban." Many analysts like Amin Saikal describe the Taliban as developing into a proxy force for Pakistan's regional interests. The Taliban started shelling Kabul in early 1995 but were defeated by forces of the Islamic State government under Ahmad Shah Massoud. Amnesty International, referring to the Taliban offensive, wrote in a 1995 report: The Taliban's early victories in 1994 were followed by a series of defeats that resulted in heavy losses. The Taliban's first major offensive against the important western city of Herat, under the rule of Islamic state ally Ismail Khan, in February 1995 was defeated when Massoud airlifted 2,000 of his own core forces from Kabul to help defend Herat. Ahmed Rashid writes: "The Taliban had now been decisively pushed back on two fronts by the government and their political and military leadership was in disarray. Their image as potential peacemakers was badly dented, for in the eyes of many Afghans they had become nothing more than just another warlord party." International observers already speculated that the Taliban as a country-wide organization might have "run its course". Mullah Omar, however, consolidated his control of the Taliban and with foreign help rebuilt and re-equipped his forces. Pakistan increased its support to the Taliban. Its military advisers oversaw the restructuring of Taliban forces. The country provided armored pick-up trucks and other military equipment. Saudi Arabia provided the funding. Furthermore, there was a massive influx of 25,000 new Taliban fighters, many of them recruited in Pakistan. This enabled the Taliban to capture Herat to the west of Kabul in a surprise attack against the forces of Ismail Khan in September 1995. A nearly one-year siege and bombardment campaign against Kabul, however, was again defeated by Massoud's forces. Massoud and Rabbani meanwhile kept working on an internal Afghan peace process – successfully. By February 1996, all of Afghanistan's armed factions – except for the Taliban – had agreed to take part in the peace process and to set up a peace council to elect a new interim president. Many Pashtun areas under Taliban control had representatives also advocating for a peace agreement with the Islamic State government. But Taliban leader Mullah Omar and the Kandaharis surrounding him wanted to expand the war. At that point the Taliban leadership and their foreign supporters decided they needed to act quickly before the government could consolidate the new understanding between the parties. The Taliban moved against Jalalabad, under the control of the Pashtun Jalalabad Shura, to the east of Kabul. Part of the Jalalabad Shura was bribed with millions of dollars by the Taliban's foreign sponsors, especially Saudi Arabia, to vacate their positions. The Taliban's battle for Jalalabad was directed by Pakistani military advisers. Hundreds of Taliban crossed the Afghan-Pakistani border moving on Jalalabad from Pakistan and thereby suddenly placed to the east of Kabul. This left the capital city Kabul "wide open" to many sides as Ismail Khan had been defeated to the west, Gulbuddin Hekmatyar had vacated his positions to the south and the fall and surrender of Jalalabad had suddenly opened a new front to the east. At that point Massoud decided to conduct a strategic retreat through a northern corridor, according to Ahmed Rashid, "knowing he could not defend [Kabul] from attacks coming from all four points of the compass. Nor did he want to lose the support of Kabul's population by fighting for the city and causing more bloodshed." On September 26, 1996, as the Taliban with military support by Pakistan and financial support by Saudi Arabia prepared for another major offensive, Massoud ordered a full retreat from Kabul. The Taliban marched into Kabul on September 27, 1996, and established the Islamic Emirate of Afghanistan. Massoud and his troops retreated to the northeast of Afghanistan which became the base for the still internationally recognized Islamic State of Afghanistan. Resistance against the Taliban (1996–2001) United Front against the Taliban Ahmad Shah Massoud created the United Front (Northern Alliance) against the Taliban advance. The United Front included forces and leaders from different political backgrounds as well as from all ethnicities of Afghanistan. From the Taliban conquest in 1996 until November 2001, the United Front controlled territory in which roughly 30% of Afghanistan's population was living, in provinces such as Badakhshan, Kapisa, Takhar and parts of Parwan, Kunar, Nuristan, Laghman, Samangan, Kunduz, Ghōr and Bamyan. Meanwhile, the Taliban imposed their repressive regime in the parts of Afghanistan under their control. Hundreds of thousands of people fled to Northern Alliance territory, Pakistan and Iran. Massoud's soldiers held some 1,200 Taliban prisoners in the Panjshir Valley, 122 of them foreign Muslims who had come to Afghanistan to fight a jihad. In 1998, after the defeat of Abdul Rashid Dostum's faction in Mazar-i-Sharif, Ahmad Shah Massoud remained the only main leader of the United Front in Afghanistan and the only leader who was able to defend vast parts of his area against the Taliban. Most major leaders including the Islamic State's President Burhanuddin Rabbani, Abdul Rashid Dostum, and others, were living in exile. During this time, commentators remarked that "The only thing standing in the way of future Taliban massacres is Ahmad Shah Massoud." Massoud stated that the Taliban repeatedly offered him a position of power to make him stop his resistance. He declined, declaring the differences between their ideology and his own pro-democratic outlook on society to be insurmountable. Massoud wanted to convince the Taliban to join a political process leading towards democratic elections in a foreseeable future. He also predicted that without assistance from Pakistan and external extremist groups, the Taliban would lose their hold on power. In early 2001, the United Front employed a new strategy of local military pressure and global political appeals. Resentment was increasingly gathering against Taliban rule from the bottom of Afghan society including the Pashtun areas. At the same time, Massoud was very wary not to revive the failed Kabul government of the early 1990s. Already in 1999 the United Front leadership ordered the training of police forces specifically to keep order and protect the civilian population in case the United Front would be successful. Cross-factional negotiations From 1999 onwards, a renewed process was set into motion by the Tajik Ahmad Shah Massoud and the Pashtun Abdul Haq to unite all the ethnicities of Afghanistan. Massoud united the Tajiks, Hazara and Uzbeks as well as several Pashtun commanders under his United Front. Besides meeting with Pashtun tribal leaders and acting as a point of reference, Abdul Haq received increasing numbers of Pashtun Taliban themselves who were secretly approaching him. Some commanders who had worked for the Taliban military apparatus agreed to the plan to topple the Taliban regime as the Taliban lost support even among the Pashtuns. Senior diplomat and Afghanistan expert Peter Tomsen wrote that "[t]he 'Lion of Kabul' [Abdul Haq] and the 'Lion of Panjshir' [Ahmad Shah Massoud] would make a formidable anti-Taliban team if they combined forces. Haq, Massoud, and Karzai, Afghanistan's three leading moderates, could transcend the Pashtun – non-Pashtun, north-south divide." Steve Coll referred to this plan as a "grand Pashtun-Tajik alliance". The senior Hazara and Uzbek leaders took part in the process just like later Afghan president Hamid Karzai. They agreed to work under the banner of the exiled Afghan king Zahir Shah in Rome. In November 2000, leaders from all ethnic groups were brought together in Massoud's headquarters in northern Afghanistan, travelling from other parts of Afghanistan, Europe, the United States, Pakistan and India to discuss a Loya Jirga for a settlement of Afghanistan's problems and to discuss the establishment of a post-Taliban government. In September 2001, an international official who met with representatives of the alliance remarked, "It's crazy that you have this today ... Pashtuns, Tajiks, Uzbeks, Hazara ... They were all ready to buy in to the process". In early 2001, Ahmad Shah Massoud with leaders from all ethnicities of Afghanistan addressed the European Parliament in Brussels, asking the international community to provide humanitarian aid to the people of Afghanistan. He stated that the Taliban and al-Qaeda had introduced "a very wrong perception of Islam" and that without the support of Pakistan and Bin Laden the Taliban would not be able to sustain their military campaign for up to a year. On that visit to Europe, he also warned the U.S. about Bin Laden. The areas of Massoud Life in the areas under direct control of Massoud was different from the life in the areas under Taliban or Dostum's control. In contrast to the time of chaos in which all structures had collapsed in Kabul, Massoud was able to control most of the troops under his direct command well during the period starting in late 1996. Massoud always controlled the Panjshir, Takhar, parts of Parwan and Badakhshan during the war. Some other provinces (notably Kunduz, Baghlan, Nuristan and the north of Kabul) were captured by his forces from the Taliban and lost again from time to time as the frontlines varied. Massoud created democratic institutions which were structured into several committees: political, health, education and economic. Still, many people came to him personally when they had a dispute or problem and asked him to solve their problems. In September 2000, Massoud signed the Declaration of the Essential Rights of Afghan Women drafted by Afghan women. The declaration established gender equality in front of the law and the right of women to political participation, education, work, freedom of movement and speech. In the areas of Massoud, women and girls did not have to wear the Afghan burqa by law. They were allowed to work and to go to school. Although it was a time of war, girls' schools were operating in some districts. In at least two known instances, Massoud personally intervened against cases of forced marriage in favour of the women to make their own choice. While it was Massoud's stated personal conviction that men and women are equal and should enjoy the same rights, he also had to deal with Afghan traditions which he said would need a generation or more to overcome. In his opinion, that could only be achieved through education. Author Pepe Escobar wrote in Asia Times: Humayun Tandar, who took part as an Afghan diplomat in the 2001 International Conference on Afghanistan in Bonn, said that "strictures of language, ethnicity, region were [also] stifling for Massoud. That is why ... he wanted to create a unity which could surpass the situation in which we found ourselves and still find ourselves to this day." This applied also to strictures of religion. Jean-José Puig describes how Massoud often led prayers before a meal or at times asked his fellow Muslims to lead the prayer but also did not hesitate to ask the Jewish Princeton Professor Michael Barry or his Christian friend Jean-José Puig: "Jean-José, we believe in the same God. Please, tell us the prayer before lunch or dinner in your own language." International relations U.S. policy regarding Massoud, the Taliban and Afghanistan remained ambiguous and differed between the various U.S. government agencies. In 1997, U.S. State Department's Robin Raphel suggested to Massoud he should surrender to the Taliban. He soundly rejected the proposal. At one point in the war, in 1997, two top foreign policy officials in the Clinton administration flew to northern Afghanistan in an attempt to convince Massoud not to take advantage of a strategic opportunity to make crucial gains against the Taliban. In 1998, a U.S. Defense Intelligence Agency analyst, Julie Sirrs, visited Massoud's territories privately, having previously been denied official permission to do so by her agency. She reported that Massoud had conveyed warnings about strengthened ties between the Taliban and foreign Islamist terrorists. Returning home, she was sacked from her agency for insubordination, because at that time the U.S. administration had no trust in Massoud. In the meantime, the only collaboration between Massoud and another U.S. intelligence service, the Central Intelligence Agency (CIA), consisted of an effort to trace Osama bin Laden following the 1998 embassy bombings. The U.S. and the European Union provided no support to Massoud for the fight against the Taliban. A change of policy, lobbied for by CIA officers on the ground who had visited the area of Massoud, regarding support to Massoud, was underway in the course of 2001. According to Steve Coll's book Ghost Wars (who won the 2005 Pulitzer Prize for General Non-Fiction): U.S. Congressman Dana Rohrabacher also recalled: [B]etween Bush's inauguration and 9/11, I met with the new national security staff on 3 occasions, including one meeting with Condoleezza Rice to discuss Afghanistan. There were, in fact, signs noted in an overview story in The Washington Post about a month ago that some steps were being made to break away from the previous administration's Afghan policy. CIA lawyers, working with officers in the Near East Division and Counterterrorist Center, began to draft a formal, legal presidential finding for Bush's signature authorizing a new covert action program in Afghanistan, the first in a decade that sought to influence the course of the Afghan war in favour of Massoud. This change in policy was finalized in August 2001 when it was too late. After Pakistan had funded, directed and supported the Taliban's rise to power in Afghanistan, Massoud and the United Front received some assistance from India. The assistance provided by India was extensive, including uniforms, ordnance, mortars, small armaments, refurbished Kalashnikovs, combat and winter clothes, as well as funds. India was particularly concerned about Pakistan's Taliban strategy and the Islamic militancy in its neighborhood; it provided U.S.$70 million in aid including two Mi-17 helicopters, three additional helicopters in 2000 and US$8 million worth of high-altitude equipment in 2001. Also In the 1990s, India had run a field hospital at Farkor on the Tajik-Afghan border to treat wounded fighters from the then Northern Alliance that was battling the Taliban regime in Afghanistan. It was at the very same hospital that the Northern Alliance leader Ahmed Shah Masood was pronounced dead after being assassinated just two days before the 9/11 terror strikes in 2001. Furthermore, the alliance supposedly also received minor aid from Tajikistan, Russia and Iran because of their opposition to the Taliban and the Pakistani control over the Taliban's Emirate. Their support, however, remained limited to the most needed things. Meanwhile, Pakistan engaged up to 28,000 Pakistani nationals and regular Pakistani army troops to fight alongside the Taliban and Al Qaeda forces against Massoud. In April 2001, the president of the European Parliament, Nicole Fontaine (who called Massoud the "pole of liberty in Afghanistan"), invited Massoud with the support of French and Belgian politicians to address the European Parliament in Brussels, Belgium. In his speech, he asked for humanitarian aid for the people of Afghanistan. Massoud further went on to warn that his intelligence agents had gained limited knowledge about a large-scale terrorist attack on U.S. soil being imminent. Assassination Massoud, then aged 48, was the target of an assassination plot in Khwājah Bahā ud Dīn (Khvājeh Bahāuḏḏīn), Takhar Province in northeastern Afghanistan on September 9, 2001. The attackers' names were alternately given as Dahmane Abd al-Sattar, husband of Malika El Aroud, and Bouraoui el-Ouaer; or 34-year-old Karim Touzani and 26-year-old Kacem Bakkali. The attackers claimed to be Belgians originally from Morocco. According to Le Monde they transited through the municipality of Molenbeek. Their passports turned out to be stolen and their nationality was later determined to be Tunisian. Waiting for almost three weeks (during which they also interviewed Burhanuddin Rabbani and Abdul Rasul Sayyaf) for an interview opportunity, on September 8, 2001, an aide to Massoud recalls the would-be suicide attackers "were so worried" and threatened to leave if the interview did not happen in the next 24 hours (until September 10, 2001). They were finally granted an interview. During the interview, they set off a bomb composed of explosives hidden in the camera and in a battery-pack belt. Massoud died in a helicopter that was taking him to an Indian military field hospital at Farkhor in nearby Tajikistan. The explosion also killed Mohammed Asim Suhail, a United Front official, while Mohammad Fahim Dashty and Massoud Khalili were injured. One of the suicide attackers, Bouraoui, was killed by the explosion, while Dahmane Abd al-Sattar was captured and shot while trying to escape. Despite initial denials by the United Front, news of Massoud's death was reported almost immediately, appearing on the BBC, and in European and North American newspapers on September 10, 2001. On September 16, the United Front officially announced that Massoud had died of injuries in the suicide attack. Massoud was buried in his home village of Bazarak in the Panjshir Valley. The funeral, although in a remote rural area, was attended by hundreds of thousands of people. Massoud had survived assassination attempts over a period of 26 years, including attempts made by al-Qaeda, the Taliban, the Pakistani ISI and before them the Soviet KGB, the Afghan communist KHAD and Hekmatyar. The first attempt on Massoud's life was carried out by Hekmatyar and two Pakistani ISI agents in 1975 when Massoud was 22 years old. In early 2001, al-Qaeda would-be assassins were captured by Massoud's forces while trying to enter his territory. Connection to September 11, 2001 The assassination of Massoud is considered to have a strong connection to the September 11 attacks in 2001 on U.S. soil, which killed nearly 3,000 people. It appeared to have been the major terrorist attack which Massoud had warned against in his speech to the European Parliament several months earlier. In late 2001, a computer was seized that was stolen from an office used by al-Qaeda immediately after the fall of Kabul in November. This computer was mainly used by Aiman al-Zawahri and contained the letter with the interview request for Massoud. The two assassins had completed military training in training camps in Afghanistan at the end of 2000 and were selected for the suicide mission in the spring or early summer of the following year. The Afghan publicist Waheed Muzhda, who worked for the Taliban in the Foreign Ministry, confirmed the two assassins met with al-Qaeda officials in Kandahar and bin Laden and al-Zawahri saw them off when they left. Following the assassination, bin Laden had an emissary deliver Dahmane Abd al-Sattar's widow a letter with $500 in an envelope to settle a debt. An al-Qaeda magazine in Saudi Arabia later published a biography of Youssef al-Aayyiri, who headed al-Qaeda's operations in Saudi Arabia from 2002, which described al-Qaeda's involvement in Massoud's assassination. Osama bin Laden commissioned the assassination attempt to appease the Taliban because of the imminent terrorist attacks in the US, which would cause serious problems for the Taliban. The Taliban denied any involvement in Massoud's assassination, and it is very unlikely that they were privy to the assassination plans. There were a few minor attacks by the Taliban after the attack, but no major offensive. Investigative commission In April 2003, the Karzai administration created a commission to investigate the assassination of Massoud. In 2003, French investigators and the FBI were able to trace the provenance of the camera used in the assassination, which had been stolen in France some time earlier. Legacy National Hero of Afghanistan Massoud was the only chief Afghan leader who never left Afghanistan in the fight against the Soviet Union and later in the fight against the Taliban Emirate. In the areas under his direct control, such as Panjshir, some parts of Parwan and Takhar, Massoud established democratic institutions. One refugee who cramped his family of 27 into an old jeep to flee from the Taliban to the area of Massoud described Massoud's territory in 1997 as "the last tolerant corner of Afghanistan". In 2001, the Afghan interim government under president Hamid Karzai officially awarded Massoud the title of "Hero of the Afghan Nation". One analyst in 2004 said: One man holds a greater political punch than all 18 living [Afghan] presidential candidates combined. Though already dead for three years.... Since his death on September 9, 2001 at the hands of two al Qaeda-linked Islamic radicals, Massoud has been transformed from mujahedin to national heroif not saint. Pictures of Massoud, the Afghan mujahedin who battled the Soviets, other warlords, and the Taliban for more than 20 years, vastly outnumber those of any other Afghan including those of Karzai. Today Panjshir, the home of Massoud, is arguably the most peaceful place in the entire country. A small US military reconstruction team is based here, but there are none of the signs of foreign occupation that exist elsewhere. Even Afghan soldiers are few and far between. Instead, the people like to boast about how they keep their own security. A Massoud Foundation was established in 2003, to provide humanitarian assistance to Afghans, especially in the fields of health care and education. It also runs programs in the fields of culture, construction, agriculture and welfare. A major road in Kabul was named Great Massoud Road. A monument to Massoud was installed outside the US Embassy. A street in New Delhi, India, is named after Ahmad Shah Massoud. It is the first time that such an honour has been extended to a leader from that country as part of close ties between Afghanistan and India. Magpul Massoud was a 7.62 NATO rifle produced by Magpul which was named after himself. The road near the Afghanistan Embassy is a "symbol of ties" that binds the two nations that have always "enjoyed excellent relations". His friend Abdullah Abdullah said that Massoud was different from the other guerilla leaders. "He is a hero who led a clear struggle for the values of the people". In a 2001 mourning ceremony at Moscow to honour the memory of Ahmad Shah Massoud, one-time foe Colonel Abdul Qadir stated: "Though Massoud and I used to be enemies, I am sure he deserves great respect as an outstanding military leader and, first of all, as a patriot of his country". Lion of Panjshir Massoud's byname, "Lion of Panjshir" (, "Shir-e-Panjshir"), earned for his role during the Soviet occupation, is a rhyming play on words in Persian, as the name of the valley means "five lions". The Wall Street Journal referred to Massoud as "The Afghan Who Won the Cold War", referring to the global significance of the Soviet defeat in Afghanistan for the subsequent collapse of the Eastern Bloc. Honors outside Afghanistan In 2007, the government of India decided to name a road in New Delhi's Chanakyapuri district after Massoud. In February 2021, the Council of Paris in France honored Massoud by installing a plaque in the 8th arrondissement of Paris. The decision reflected Massoud's unique connections with France. In March 2021, the Mayor of Paris named a pathway in the Champs-Élysées gardens after Massoud. The ceremony was attended by Massoud's son and former president Hamid Karzai. Civilian orders Tajikistan: Order of Ismoili Somoni – posthumously awarded on September 2, 2021. Views on Pakistan and potential al-Qaeda attacks Although Pakistan were supporting the mujahideen groups during the Soviet-Afghan War, Ahmad Shah Massoud increasingly distrusted the Pakistanis and eventually kept his distance from them. In a 1999 interview, Massoud says "They [Pakistan] are trying to turn us into a colony. Without them there would be no war". In the spring 2001, Ahmad Shah Massoud addressed the European Parliament in Brussels, saying that Pakistan was behind the situation in Afghanistan. He also said that he believed that, without the support of Pakistan, Osama bin Laden, and Saudi Arabia, the Taliban would not be able to sustain their military campaign for up to a year. He said the Afghan population was ready to rise against them. Addressing the United States specifically, he warned that should the U.S. not work for peace in Afghanistan and put pressure on Pakistan to cease their support to the Taliban, the problems of Afghanistan would soon become the problems of the U.S. and the world. Declassified Defense Intelligence Agency (DIA) documents from November 2001 show that Massoud had gained "limited knowledge... regarding the intentions of al-Qaeda to perform a terrorist act against the U.S. on a scale larger than the 1998 bombing of the U.S. embassies in Kenya and Tanzania." They noted that he warned about such attacks. Succession and resistance to Taliban by his son In September 2019, his son Ahmad Massoud was declared as his successor. Following the 2021 Taliban offensive and the Fall of Kabul, Massoud allied with self-proclaimed acting president Amrullah Saleh and established the National Resistance Front of Afghanistan to the Taliban in the Panjshir Valley. Massoud called for West's support to resist the Taliban. Personal life Massoud was married to Sediqa Massoud. They had one son, Ahmad Massoud (born in 1989) and five daughters (Fatima born in 1992, Mariam born in 1993, Ayesha born in 1995, Zohra born in 1996 and Nasrine born in 1998). In 2005 Sediqa Massoud published a personal account on her life with Massoud (co-authored by two women's rights activists and friends of Sediqa Massoud, Chékéba Hachemi and ) called "Pour l'amour de Massoud" (For the love of Massoud), in which she describes a decent and loving husband. Massoud liked reading and had a library of 3,000 books at his home in Panjshir. He used to read the works of revolutionaries Mao Zedong and Che Guevara, and was a great admirer of Charles de Gaulle, founder of the French Fifth Republic. Massoud said his favorite author was Victor Hugo and he was also a fan of classical Persian poetry, including the works of Bidel and Hafez. He was keen at playing football and chess. Massoud's reputation for fearlessness is illustrated by a story about him told in Afghanistan, which cannot be confirmed. Once, while inspecting the front lines with a deputy, Massoud's driver had become lost and driven into the middle of a Taliban encampment. In tremendous peril, since he was recognized immediately, Massoud demanded to see the Taliban commander, making polite conversation for just long enough to bluff that he had arrived intentionally and not accidentally. The confused Taliban allowed him to leave. Massoud's family since his death have had a great deal of prestige in the politics of Afghanistan. One of his six brothers, Ahmad Zia Massoud, was the Vice President of Afghanistan from 2004 until 2009 under the first democratically elected government of Afghanistan. Unsuccessful attempts have been made on the life of Ahmad Zia Massoud in 2004 and late 2009. The Associated Press reported that eight Afghans died in the attempt on Ahmad Zia Massoud's life. Ahmad Zia Massoud leads the National Front of Afghanistan (a United Front group). Another brother, Ahmad Wali Massoud, was Afghanistan's Ambassador to the United Kingdom from 2002 to 2006. He was a member of Abdullah Abdullah's National Coalition of Afghanistan (another United Front group). In literature Essay Sebastian Junger, one of the last Western journalists to interview Massoud in depth, featured him in an essay in his 2002 collection, Fire. Fiction Massoud is the subject of Ken Follett's 1986 novel Lie Down With Lions, about the Soviet-Afghan War. He also is featured as a historical figure in James McGee's 1989 thriller, Crow's War. Massoud is the subject of Olivier Weber's novel Massoud's Confession, about the Islam of Enlightenment and the need to reform religious practices. Massoud is played by Mido Hamada in the 2006 miniseries The Path to 9/11. Notes References Further reading Sandy Gall (2021): Afghan Napoleon: The Life of Ahmad Shah Massoud. London: Haus Publishing.

Atlantis () is a fictional island mentioned in Plato's works Timaeus and Critias as part of an allegory on the hubris of nations. In the story, Atlantis is described as a naval empire that ruled all Western parts of the known world, making it the literary counter-image of the Achaemenid Empire. After an ill-fated attempt to conquer "Ancient Athens," Atlantis falls out of favor with the deities and submerges into the Atlantic Ocean. Since Plato describes Athens as resembling his ideal state in the Republic, the Atlantis story is meant to bear witness to the superiority of his concept of a state. Despite its minor importance in Plato's work, the Atlantis story has had a considerable impact on literature. The allegorical aspect of Atlantis was taken up in utopian works of several Renaissance writers, such as Francis Bacon's New Atlantis and Thomas More's Utopia. On the other hand, nineteenth-century amateur scholars misinterpreted Plato's narrative as historical tradition, most famously Ignatius L. Donnelly in his Atlantis: The Antediluvian World. Plato's vague indications of the time of the events (more than 9,000 years before his time) and the alleged location of Atlantis ("beyond the Pillars of Hercules") gave rise to much pseudoscientific speculation. As a consequence, Atlantis has become a byword for any and all supposed advanced prehistoric lost civilizations and continues to inspire contemporary fiction, from comic books to films. While present-day philologists and classicists agree on the story's fictional nature, there is still debate on what served as its inspiration. Plato is known to have freely borrowed some of his allegories and metaphors from older traditions, as he did with the story of Gyges. This led a number of scholars to suggest possible inspiration of Atlantis from Egyptian records of the Thera eruption, the Sea Peoples invasion, or the Trojan War. Others have rejected this chain of tradition as implausible and insist that Plato created an entirely fictional account, drawing loose inspiration from contemporary events such as the failed Athenian invasion of Sicily in 415–413 BC or the destruction of Helike in 373 BC. Plato's dialogues Timaeus The only primary sources for Atlantis are Plato's dialogues Timaeus and Critias; all other mentions of the island are based on them. The dialogues claim to quote Solon, who visited Egypt between 590 and 580 BC; they state that he translated Egyptian records of Atlantis. Plato introduced Atlantis in Timaeus, written in 360 BC: The four people appearing in those two dialogues are the politicians Critias and Hermocrates as well as the philosophers Socrates and Timaeus of Locri, although only Critias speaks of Atlantis. In his works Plato makes extensive use of the Socratic method in order to discuss contrary positions within the context of a supposition. The Timaeus begins with an introduction, followed by an account of the creations and structure of the universe and ancient civilizations. In the introduction, Socrates muses about the perfect society, described in Plato's Republic (), and wonders if he and his guests might recollect a story which exemplifies such a society. Critias mentions a tale he considered to be historical, that would make the perfect example, and he then follows by describing Atlantis as is recorded in the Critias. In his account, ancient Athens seems to represent the "perfect society" and Atlantis its opponent, representing the very antithesis of the "perfect" traits described in the Republic. Critias According to Critias, the Hellenic deities of old divided the land so that each deity might have their own lot; Poseidon was appropriately, and to his liking, bequeathed the island of Atlantis. The island was larger than Ancient Libya and Asia Minor combined, but it was later sunk by an earthquake and became an impassable mud shoal, inhibiting travel to any part of the ocean. Plato asserted that the Egyptians described Atlantis as an island consisting mostly of mountains in the northern portions and along the shore and encompassing a great plain in an oblong shape in the south "extending in one direction three thousand stadia [about 555 km; 345 mi], but across the center inland it was two thousand stadia [about 370 km; 230 mi]." Fifty stadia [9 km; 6 mi] from the coast was a mountain that was low on all sides ... broke it off all round about ... the central island itself was five stades in diameter [about 0.92 km; 0.57 mi]. In Plato's metaphorical tale, Poseidon fell in love with Cleito, the daughter of Evenor and Leucippe, who bore him five pairs of male twins. The eldest of these, Atlas, was made rightful king of the entire island and the ocean (called the Atlantic Ocean in his honor), and was given the mountain of his birth and the surrounding area as his fiefdom. Atlas's twin Gadeirus, or Eumelus in Greek, was given the extremity of the island toward the pillars of Hercules. The other four pairs of twins—Ampheres and Evaemon, Mneseus and Autochthon, Elasippus and Mestor, and Azaes and Diaprepes—were also given "rule over many men, and a large territory." Poseidon carved the mountain where his love dwelt into a palace and enclosed it with three circular moats of increasing width, varying from one to three stadia and separated by rings of land proportional in size. The Atlanteans then built bridges northward from the mountain, making a route to the rest of the island. They dug a great canal to the sea, and alongside the bridges carved tunnels into the rings of rock so that ships could pass into the city around the mountain; they carved docks from the rock walls of the moats. Every passage to the city was guarded by gates and towers, and a wall surrounded each ring of the city. The walls were constructed of red, white, and black rock, quarried from the moats, and were covered with brass, tin, and the precious metal orichalcum, respectively. According to Critias, 9,000 years before his lifetime a war took place between those outside the Pillars of Hercules at the Strait of Gibraltar and those who dwelt within them. The Atlanteans had conquered the parts of Libya within the Pillars of Hercules, as far as Egypt, and the European continent as far as Tyrrhenia, and had subjected its people to slavery. The Athenians led an alliance of resistors against the Atlantean empire, and as the alliance disintegrated, prevailed alone against the empire, liberating the occupied lands. The logographer Hellanicus of Lesbos wrote an earlier work entitled Atlantis, of which only a few fragments survive. Hellanicus' work appears to have been a genealogical one concerning the daughters of Atlas (Ἀτλαντὶς in Greek means "of Atlas"), but some authors have suggested a possible connection with Plato's island. John V. Luce notes that when Plato writes about the genealogy of Atlantis's kings, he writes in the same style as Hellanicus, suggesting a similarity between a fragment of Hellanicus's work and an account in the Critias. Rodney Castleden suggests that Plato may have borrowed his title from Hellanicus, who may have based his work on an earlier work about Atlantis. Castleden has pointed out that Plato wrote of Atlantis in 359 BC, when he returned to Athens from Sicily. He notes a number of parallels between the physical organisation and fortifications of Syracuse and Plato's description of Atlantis. Gunnar Rudberg was the first who elaborated upon the idea that Plato's attempt to realize his political ideas in the city of Syracuse could have heavily inspired the Atlantis account. Interpretations Ancient Some ancient writers viewed Atlantis as fictional or metaphorical myth; others believed it to be real. Aristotle believed that Plato, his teacher, had invented the island to teach philosophy. The philosopher Crantor, a student of Plato's student Xenocrates, is cited often as an example of a writer who thought the story to be historical fact. His work, a commentary on Timaeus, is lost, but Proclus, a Neoplatonist of the fifth century AD, reports on it. The passage in question has been represented in the modern literature either as claiming that Crantor visited Egypt, had conversations with priests, and saw hieroglyphs confirming the story, or, as claiming that he learned about them from other visitors to Egypt. Proclus wrote: The next sentence is often translated "Crantor adds, that this is testified by the prophets of the Egyptians, who assert that these particulars [which are narrated by Plato] are written on pillars which are still preserved." But in the original, the sentence starts not with the name Crantor but with the ambiguous He; whether this referred to Crantor or to Plato is the subject of considerable debate. Proponents of both Atlantis as a metaphorical myth and Atlantis as history have argued that the pronoun refers to Crantor. Alan Cameron argues that the pronoun should be interpreted as referring to Plato, and that, when Proclus writes that "we must bear in mind concerning this whole feat of the Athenians, that it is neither a mere myth nor unadorned history, although some take it as history and others as myth", he is treating "Crantor's view as mere personal opinion, nothing more; in fact he first quotes and then dismisses it as representing one of the two unacceptable extremes". Cameron also points out that whether he refers to Plato or to Crantor, the statement does not support conclusions such as Otto Muck's "Crantor came to Sais and saw there in the temple of Neith the column, completely covered with hieroglyphs, on which the history of Atlantis was recorded. Scholars translated it for him, and he testified that their account fully agreed with Plato's account of Atlantis" or J. V. Luce's suggestion that Crantor sent "a special enquiry to Egypt" and that he may simply be referring to Plato's own claims. Another passage from the commentary by Proclus on the Timaeus gives a description of the geography of Atlantis: Marcellus remains unidentified. Other ancient historians and philosophers who believed in the existence of Atlantis were Strabo and Posidonius. Some have theorized that, before the sixth century BC, the "Pillars of Hercules" may have applied to mountains on either side of the Gulf of Laconia, and also may have been part of the pillar cult of the Aegean. The mountains stood at either side of the southernmost gulf in Greece, the largest in the Peloponnese, and it opens onto the Mediterranean Sea. This would have placed Atlantis in the Mediterranean, lending credence to many details in Plato's discussion. The fourth-century historian Ammianus Marcellinus, relying on a lost work by Timagenes, a historian writing in the first century BC, writes that the Druids of Gaul said that part of the inhabitants of Gaul had migrated there from distant islands. Some have understood Ammianus's testimony as a claim that at the time of Atlantis's sinking into the sea, its inhabitants fled to western Europe; but Ammianus, in fact, says that "the Drasidae (Druids) recall that a part of the population is indigenous but others also migrated in from islands and lands beyond the Rhine" (Res Gestae 15.9), an indication that the immigrants came to Gaul from the north (Britain, the Netherlands, or Germany), not from a theorized location in the Atlantic Ocean to the south-west. Instead, the Celts who dwelled along the ocean were reported to venerate twin gods, (Dioscori), who appeared to them coming from that ocean. Jewish and Christian During the early first century, the Hellenistic Jewish philosopher Philo wrote about the destruction of Atlantis in his On the Eternity of the World, xxvi. 141, in a longer passage allegedly citing Aristotle's successor Theophrastus: The theologian Joseph Barber Lightfoot (Apostolic Fathers, 1885, II, p. 84) noted on this passage: "Clement may possibly be referring to some known, but hardly accessible land, lying without the pillars of Hercules. But more probably he contemplated some unknown land in the far west beyond the ocean, like the fabled Atlantis of Plato ..." Other early Christian writers wrote about Atlantis, although they had mixed views on whether it once existed or was an untrustworthy myth of pagan origin. Tertullian believed Atlantis was once real and wrote that in the Atlantic Ocean once existed "[the isle] that was equal in size to Libya or Asia" referring to Plato's geographical description of Atlantis. The early Christian apologist writer Arnobius also believed Atlantis once existed, but blamed its destruction on pagans. Cosmas Indicopleustes in the sixth century wrote of Atlantis in his Christian Topography in an attempt to prove his theory that the world was flat and surrounded by water: Modern Aside from Plato's original account, modern interpretations regarding Atlantis are an amalgamation of diverse, speculative movements that began in the sixteenth century, when scholars began to identify Atlantis with the New World. Francisco Lopez de Gomara was the first to state that Plato was referring to America, as did Francis Bacon and Alexander von Humboldt; Janus Joannes Bircherod said in 1663 orbe novo non-novo ("the New World is not new"). Athanasius Kircher accepted Plato's account as literally true, describing Atlantis as a small continent in the Atlantic Ocean. Contemporary perceptions of Atlantis share roots with Mayanism, which can be traced to the beginning of the Modern Age, when European imaginations were fueled by their initial encounters with the indigenous peoples of the Americas. From this era sprang apocalyptic and utopian visions that would inspire many subsequent generations of theorists. Most of these interpretations are considered pseudohistory, pseudoscience, or pseudoarchaeology, as they have presented their works as academic or scientific, but lack the standards or criteria. The Flemish cartographer and geographer Abraham Ortelius is believed to have been the first person to imagine that the continents were joined before drifting to their present positions. In the 1596 edition of his Thesaurus Geographicus he wrote: "Unless it be a fable, the island of Gadir or Gades will be the remaining part of the island of Atlantis or America, which was not sunk (as Plato reports in the Timaeus) so much as torn away from Europe and Africa by earthquakes and flood... The traces of the ruptures are shown by the projections of Europe and Africa and the indentations of America in the parts of the coasts of these three said lands that face each other to anyone who, using a map of the world, carefully considered them. So that anyone may say with Strabo in Book 2, that what Plato says of the island of Atlantis on the authority of Solon is not a figment." Early influential literature The term "utopia" (from "no place") was coined by Sir Thomas More in his sixteenth-century work of fiction Utopia. Inspired by Plato's Atlantis and travelers' accounts of the Americas, More described an imaginary land set in the New World. His idealistic vision established a connection between the Americas and utopian societies, a theme that Bacon discussed in The New Atlantis (). A character in the narrative gives a history of Atlantis that is similar to Plato's and places Atlantis in America. People had begun believing that the Mayan and Aztec ruins could possibly be the remnants of Atlantis. Impact of Mayanism Much speculation began as to the origins of the Maya, which led to a variety of narratives and publications that tried to rationalize the discoveries within the context of the Bible and that had undertones of racism in their connections between the Old and New World. The Europeans believed the indigenous people to be inferior and incapable of building that which was now in ruins and by sharing a common history, they insinuated that another race must have been responsible. In the middle and late nineteenth century, several renowned Mesoamerican scholars, starting with Charles Étienne Brasseur de Bourbourg, and including Edward Herbert Thompson and Augustus Le Plongeon, formally proposed that Atlantis was somehow related to Mayan and Aztec culture. The French scholar Brasseur de Bourbourg traveled extensively through Mesoamerica in the mid-1800s, and was renowned for his translations of Mayan texts, most notably the sacred book Popol Vuh, as well as a comprehensive history of the region. Soon after these publications, however, Brasseur de Bourbourg lost his academic credibility, due to his claim that the Maya peoples had descended from the Toltecs, people he believed were the surviving population of the racially superior civilization of Atlantis. His work combined with the skillful, romantic illustrations of Jean Frederic Waldeck, which visually alluded to Egypt and other aspects of the Old World, created an authoritative fantasy that excited much interest in the connections between worlds. Inspired by Brasseur de Bourbourg's diffusion theories, the pseudoarchaeologist Augustus Le Plongeon traveled to Mesoamerica and performed some of the first excavations of many famous Mayan ruins. Le Plongeon invented narratives, such as the kingdom of Mu saga, which romantically drew connections to him, his wife Alice, and Egyptian deities Osiris and Isis, as well as to Heinrich Schliemann, who had just discovered the ancient city of Troy from Homer's epic poetry (that had been described as merely mythical). He also believed that he had found connections between the Greek and Mayan languages, which produced a narrative of the destruction of Atlantis. Ignatius Donnelly The 1882 publication of Atlantis: the Antediluvian World by Ignatius L. Donnelly stimulated much popular interest in Atlantis. He was greatly inspired by early works in Mayanism, and like them, attempted to establish that all known ancient civilizations were descended from Atlantis, which he saw as a technologically sophisticated, more advanced culture. Donnelly drew parallels between creation stories in the Old and New Worlds, attributing the connections to Atlantis, where he believed the Biblical Garden of Eden existed. As implied by the title of his book, he also believed that Atlantis was destroyed by the Great Flood mentioned in the Bible. Donnelly is credited as the "father of the nineteenth century Atlantis revival" and is the reason the myth endures today. He unintentionally promoted an alternative method of inquiry to history and science, and the idea that myths contain hidden information that opens them to "ingenious" interpretation by people who believe they have new or special insight. Madame Blavatsky and the Theosophists Helena Petrovna Blavatsky, the founder of the Theosophists, took up Donnelly's interpretations when she wrote The Secret Doctrine (1888), which she claimed was originally dictated in Atlantis. She maintained that the Atlanteans were cultural heroes (contrary to Plato, who describes them mainly as a military threat). She believed in a form of racial evolution (as opposed to primate evolution). In her process of evolution the Atlanteans were the fourth "root race", which were succeeded by the fifth, the "Aryan race", which she identified with the modern human race. In her book, Blavatsky reported that the civilization of Atlantis reached its peak between 1,000,000 and 900,000 years ago, but destroyed itself through internal warfare brought about by the dangerous use of psychic and supernatural powers of the inhabitants. Rudolf Steiner, the founder of anthroposophy and Waldorf Schools, along with other well known Theosophists, such as Annie Besant, also wrote of cultural evolution in much the same vein. Other occultists followed the same lead, at least to the point of tracing the lineage of occult practices back to Atlantis. Among the most famous is Dion Fortune in her Esoteric Orders and Their Work. Drawing on the ideas of Rudolf Steiner and Hanns Hörbiger, Egon Friedell started his book , and thus his historical analysis of antiquity, with the ancient culture of Atlantis. The book was published in 1940. Nazism and occultism Blavatsky was also inspired by the work of the 18th-century astronomer Jean-Sylvain Bailly, who had "Orientalized" the Atlantis myth in his mythical continent of Hyperborea, a reference to Greek myths featuring a Northern European region of the same name, home to a giant, godlike race. Dan Edelstein claims that her reshaping of this theory in The Secret Doctrine provided the Nazis with a mythological precedent and a pretext for their ideological platform and their subsequent genocide. However, Blavatsky's writings mention that the Atlantean were in fact olive-skinned peoples with Mongoloid traits who were the ancestors of modern Native Americans, Mongolians, and Malayans. The idea that the Atlanteans were Hyperborean, Nordic supermen who originated in the Northern Atlantic or even in the far North, was popular in the German ariosophic movement around 1900, propagated by Guido von List and others. It gave its name to the Thule Gesellschaft, an antisemite Münich lodge, which preceded the German Nazi Party (see Thule). The scholars (1920) and Herman Wirth (1928) were the first to speak of a "Nordic-Atlantean" or "Aryan-Nordic" master race that spread from Atlantis over the Northern Hemisphere and beyond. The Hyperboreans were contrasted with the Jewish people. Party ideologist Alfred Rosenberg (in The Myth of the Twentieth Century, 1930) and SS-leader Heinrich Himmler made it part of the official doctrine. The idea was followed up by the adherents of Esoteric Nazism such as Julius Evola (1934) and, more recently, Miguel Serrano (1978). The idea of Atlantis as the homeland of the Caucasian race would contradict the beliefs of older Esoteric and Theosophic groups, which taught that the Atlanteans were non-Caucasian brown-skinned peoples. Modern Esoteric groups, including the Theosophic Society, do not consider Atlantean society to have been superior or Utopian—they rather consider it a lower stage of evolution. Edgar Cayce The clairvoyant Edgar Cayce spoke frequently of Atlantis. During his "life readings", he claimed that many of his subjects were reincarnations of people who had lived there. By tapping into their collective consciousness, the "Akashic Records" (a term borrowed from Theosophy), Cayce declared that he was able to give detailed descriptions of the lost continent. He also asserted that Atlantis would "rise" again in the 1960s (sparking much popularity of the myth in that decade) and that there is a "Hall of Records" beneath the Egyptian Sphinx which holds the historical texts of Atlantis. Recent times As continental drift became widely accepted during the 1960s, and the increased understanding of plate tectonics demonstrated the impossibility of a lost continent in the geologically recent past, most "Lost Continent" theories of Atlantis began to wane in popularity. Plato scholar Julia Annas, Regents Professor of Philosophy at the University of Arizona, had this to say on the matter: One of the proposed explanations for the historical context of the Atlantis story is that it serves as Plato's warning to his fellow citizens against their striving for naval power. Kenneth Feder points out that Critias's story in the Timaeus provides a major clue. In the dialogue, Critias says, referring to Socrates' hypothetical society: Feder quotes A. E. Taylor, who wrote, "We could not be told much more plainly that the whole narrative of Solon's conversation with the priests and his intention of writing the poem about Atlantis are an invention of Plato's fancy." Location hypotheses Since Donnelly's day, there have been dozens of locations proposed for Atlantis, to the point where the name has become a generic concept, divorced from the specifics of Plato's account. This is reflected in the fact that many proposed sites are not within the Atlantic at all. Few today are scholarly or archaeological hypotheses, while others have been made by psychic (e.g., Edgar Cayce) or other pseudoscientific means. (The Atlantis researchers Jacques Collina-Girard and Georgeos Díaz-Montexano, for instance, each claim the other's hypothesis is pseudoscience.) Many of the proposed sites share some of the characteristics of the Atlantis story (water, catastrophic end, relevant time period), but none has been demonstrated to be a true historical Atlantis. In or near the Mediterranean Sea Most of the historically proposed locations are in or near the Mediterranean Sea: islands such as Sardinia, Crete, Santorini (Thera), Sicily, Cyprus, and Malta; land-based cities or states such as Troy, Tartessos, and Tantalis (in the province of Manisa, Turkey); Israel-Sinai or Canaan; and northwestern Africa, including the Richat Structure in Mauritania. The Thera eruption, dated to the seventeenth or sixteenth century BC, caused a large tsunami that some experts hypothesize devastated the Minoan civilization on the nearby island of Crete, further leading some to believe that this may have been the catastrophe that inspired the story. In the area of the Black Sea the following locations have been proposed: Bosporus and Ancomah (a legendary place near Trabzon). Others have noted that, before the sixth century BC, the mountains on either side of the Laconian Gulf were called the "Pillars of Hercules", and they could be the geographical location being described in ancient reports upon which Plato was basing his story. The mountains stood at either side of the southernmost gulf in Greece, the largest in the Peloponnese, and that gulf opens onto the Mediterranean Sea. If from the beginning of discussions, misinterpretation of Gibraltar as the location rather than being at the Gulf of Laconia, would lend itself to many erroneous concepts regarding the location of Atlantis. Plato may have not been aware of the difference. The Laconian pillars open to the south toward Crete and beyond which is Egypt. The Thera eruption and the Late Bronze Age collapse affected that area and might have been the devastation to which the sources used by Plato referred. Significant events such as these would have been likely material for tales passed from one generation to another for almost a thousand years. In the Atlantic Ocean The location of Atlantis in the Atlantic Ocean has a certain appeal given the closely related names. Popular culture often places Atlantis there, perpetuating the original Platonic setting as they understand it. The Canary Islands and Madeira Islands have been identified as a possible location, west of the Straits of Gibraltar, but in relative proximity to the Mediterranean Sea. Detailed studies of their geomorphology and geology have demonstrated, however, that they have been steadily uplifted, without any significant periods of subsidence, over the last four million years, by geologic processes such as erosional unloading, gravitational unloading, lithospheric flexure induced by adjacent islands, and volcanic underplating. Various islands or island groups in the Atlantic were also identified as possible locations, notably the Azores. Similarly, cores of sediment covering the ocean bottom surrounding the Azores and other evidence demonstrate that it has been an undersea plateau for millions of years. The area is known for its volcanism however, which is associated with rifting along the Azores Triple Junction. The spread of the crust along the existing faults and fractures has produced many volcanic and seismic events. The area is supported by a buoyant upwelling in the deeper mantle, which some associate with an Azores hotspot. Most of the volcanic activity has occurred primarily along the Terceira Rift. From the beginning of the islands' settlement, around the 15th century, there have been about 30 volcanic eruptions (terrestrial and submarine) as well as numerous, powerful earthquakes. The island of São Miguel in the Azores is the site of the Sete Cidades volcano and caldera, which are the byproducts of historical volcanic activity in the Azores. The submerged island of Spartel near the Strait of Gibraltar has also been suggested. In Europe Several hypotheses place the sunken island in northern Europe, including Doggerland in the North Sea, and Sweden (by Olof Rudbeck in Atland, 1672–1702). Doggerland, as well as Viking Bergen Island, is thought to have been flooded by a megatsunami following the Storegga Slide of c. 6100 BC. Some have proposed the Celtic Shelf as a possible location, and that there is a link to Ireland. In 2004, Swedish physiographist Ulf Erlingsson proposed that the legend of Atlantis was based on Stone Age Ireland. He later stated that he does not believe that Atlantis ever existed but maintained that his hypothesis that its description matches Ireland's geography has a 99.8% probability. The director of the National Museum of Ireland commented that there was no archaeology supporting this. In 2011, a team, working on a documentary for the National Geographic Channel, led by Professor Richard Freund from the University of Hartford, claimed to have found possible evidence of Atlantis in southwestern Andalusia. The team identified its possible location within the marshlands of the Doñana National Park, in the area that once was the Lacus Ligustinus, between the Huelva, Cádiz, and Seville provinces, and they speculated that Atlantis had been destroyed by a tsunami, extrapolating results from a previous study by Spanish researchers, published four years earlier. Spanish scientists have dismissed Freund's speculations, claiming that he sensationalised their work. The anthropologist Juan Villarías-Robles, who works with the Spanish National Research Council, said, "Richard Freund was a newcomer to our project and appeared to be involved in his own very controversial issue concerning King Solomon's search for ivory and gold in Tartessos, the well documented settlement in the Doñana area established in the first millennium BC", and described Freund's claims as "fanciful". A similar theory had previously been put forward by a German researcher, Rainer W. Kühne, that is based only on satellite imagery and places Atlantis in the Marismas de Hinojos, north of the city of Cádiz. Before that, the historian Adolf Schulten had stated in the 1920s that Plato had used Tartessos as the basis for his Atlantis myth. Other locations Several writers, such as Flavio Barbiero as early as 1974, have speculated that Antarctica is the site of Atlantis. A number of claims involve the Caribbean, such as an alleged underwater formation off the Guanahacabibes Peninsula in Cuba. The adjacent Bahamas or the folkloric Bermuda Triangle have been proposed as well. Areas in the Pacific and Indian Oceans have also been proposed, including Indonesia (i.e. Sundaland). The stories of a lost continent off the coast of India, named "Kumari Kandam", have inspired some to draw parallels to Atlantis. Literary interpretations Ancient versions In order to give his account of Atlantis verisimilitude, Plato mentions that the story was heard by Solon in Egypt, and transmitted orally over several generations through the family of Dropides, until it reached Critias, a dialogue speaker in Timaeus and Critias. Solon had supposedly tried to adapt the Atlantis oral tradition into a poem (that if published, was to be greater than the works of Hesiod and Homer). While it was never completed, Solon passed on the story to Dropides. Modern classicists deny the existence of Solon's Atlantis poem and the story as an oral tradition. Instead, Plato is thought to be the sole inventor or fabricator. Hellanicus of Lesbos used the word "Atlantis" as the title for a poem published before Plato, a fragment of which may be Oxyrhynchus Papyrus 11, 1359. This work only describes the Atlantides, the daughters of Atlas, and has no relation to Plato's Atlantis account. In the new era, the third century AD Neoplatonist Zoticus wrote an epic poem based on Plato's account of Atlantis. Plato's work may already have inspired parodic imitation, however. Writing only a few decades after the Timaeus and Critias, the historian Theopompus of Chios wrote of a land beyond the ocean known as Meropis. This description was included in Book 8 of his Philippica, which contains a dialogue between Silenus and King Midas. Silenus describes the Meropids, a race of men who grow to twice normal size, and inhabit two cities on the island of Meropis: Eusebes (, "Pious-town") and Machimos (, "Fighting-town"). He also reports that an army of ten million soldiers crossed the ocean to conquer Hyperborea, but abandoned this proposal when they realized that the Hyperboreans were the luckiest people on earth. Heinz-Günther Nesselrath has argued that these and other details of Silenus' story are meant as imitation and exaggeration of the Atlantis story, by parody, for the purpose of exposing Plato's ideas to ridicule. Utopias and dystopias The creation of Utopian and dystopian fictions was renewed after the Renaissance, most notably in Francis Bacon's New Atlantis (1627), the description of an ideal society that he located off the western coast of America. Thomas Heyrick (1649–1694) followed him with "The New Atlantis" (1687), a satirical poem in three parts. His new continent of uncertain location, perhaps even a floating island either in the sea or the sky, serves as background for his exposure of what he described in a second edition as "A True Character of Popery and Jesuitism". The title of The New Atalantis by Delarivier Manley (1709), distinguished from the two others by the single letter, is an equally dystopian work but set this time on a fictional Mediterranean island. In it sexual violence and exploitation is made a metaphor for the hypocritical behaviour of politicians in their dealings with the general public. In Manley's case, the target of satire was the Whig Party, while in David Maclean Parry's The Scarlet Empire (1906) it is Socialism as practised in foundered Atlantis. It was followed in Russia by Velimir Khlebnikov's poem The Fall of Atlantis (Gibel' Atlantidy, 1912), which is set in a future rationalist dystopia that has discovered the secret of immortality and is so dedicated to progress that it has lost touch with the past. When the high priest of this ideology is tempted by a slave girl into an act of irrationality, he murders her and precipitates a second flood, above which her severed head floats vengefully among the stars. A slightly later work, The Ancient of Atlantis (Boston, 1915) by Albert Armstrong Manship, expounds the Atlantean wisdom that is to redeem the earth. Its three parts consist of a verse narrative of the life and training of an Atlantean wise one, followed by his Utopian moral teachings and then a psychic drama set in modern times in which a reincarnated child embodying the lost wisdom is reborn on earth. In Hispanic eyes, Atlantis had a more intimate interpretation. The land had been a colonial power which, although it had brought civilization to ancient Europe, had also enslaved its peoples. Its tyrannical fall from grace had contributed to the fate that had overtaken it, but now its disappearance had unbalanced the world. This was the point of view of Jacint Verdaguer's vast mythological epic L'Atlantida (1877). After the sinking of the former continent, Hercules travels east across the Atlantic to found the city of Barcelona and then departs westward again to the Hesperides. The story is told by a hermit to a shipwrecked mariner, who is inspired to follow in his tracks and so "call the New World into existence to redress the balance of the Old". This mariner, of course, was Christopher Columbus. Verdaguer's poem was written in Catalan, but was widely translated in both Europe and Hispano-America. One response was the similarly entitled Argentinian Atlantida of Olegario Víctor Andrade (1881), which sees in "Enchanted Atlantis that Plato foresaw, a golden promise to the fruitful race" of Latins. The bad example of the colonising world remains, however. José Juan Tablada characterises its threat in his "De Atlántida" (1894) through the beguiling picture of the lost world populated by the underwater creatures of Classical myth, among whom is the Siren of its final stanza with There is a similar ambivalence in Janus Djurhuus' six-stanza "Atlantis" (1917), where a celebration of the Faroese linguistic revival grants it an ancient pedigree by linking Greek to Norse legend. In the poem a female figure rising from the sea against a background of Classical palaces is recognised as a priestess of Atlantis. The poet recalls "that the Faroes lie there in the north Atlantic Ocean/ where before lay the poet-dreamt lands," but also that in Norse belief, such a figure only appears to those about to drown. A land lost in the distance The fact that Atlantis is a lost land has made of it a metaphor for something no longer attainable. For the American poet Edith Willis Linn Forbes, "The Lost Atlantis" stands for idealisation of the past; the present moment can only be treasured once that is realised. Ella Wheeler Wilcox finds the location of "The Lost Land" (1910) in one's carefree youthful past. Similarly, for the Irish poet Eavan Boland in "Atlantis, a lost sonnet" (2007), the idea was defined when "the old fable-makers searched hard for a word/ to convey that what is gone is gone forever". For some male poets too, the idea of Atlantis is constructed from what cannot be obtained. Charles Bewley in his Newdigate Prize poem (1910) thinks it grows from dissatisfaction with one's condition, in a dream of Atlantis. Similarly for the Australian Gary Catalano in a 1982 prose poem, it is "a vision that sank under the weight of its own perfection". W. H. Auden, however, suggests a way out of such frustration through the metaphor of journeying toward Atlantis in his poem of 1941. While travelling, he advises the one setting out, you will meet with many definitions of the goal in view, only realising at the end that the way has all the time led inward. Epic narratives A few late-19th century verse narratives complement the genre fiction that was beginning to be written at the same period. Two of them report the disaster that overtook the continent as related by long-lived survivors. In Frederick Tennyson's Atlantis (1888), an ancient Greek mariner sails west and discovers an inhabited island which is all that remains of the former kingdom. He learns of its end and views the shattered remnant of its former glory, from which a few had escaped to set up the Mediterranean civilisations. In the second, Mona, Queen of Lost Atlantis: An Idyllic Re-embodiment of Long Forgotten History (Los Angeles CA 1925) by James Logue Dryden (1840–1925), the story is told in a series of visions. A Seer is taken to Mona's burial chamber in the ruins of Atlantis, where she revives and describes the catastrophe. There follows a survey of the lost civilisations of Hyperborea and Lemuria as well as Atlantis, accompanied by much spiritualist lore. William Walton Hoskins (1856–1919) admits to the readers of his Atlantis and other poems (Cleveland OH, 1881), that he is only 24. Its melodramatic plot concerns the poisoning of the descendant of god-born kings. The usurping poisoner is poisoned in his turn, following which the continent is swallowed in the waves. Asian gods people the landscape of The Lost Island (Ottawa 1889) by Edward Taylor Fletcher (1816–97). An angel foresees impending catastrophe and that the people will be allowed to escape if their semi-divine rulers will sacrifice themselves. A final example, Edward N. Beecher's The Lost Atlantis or The Great Deluge of All (Cleveland OH, 1898) is just a doggerel vehicle for its author's opinions: that the continent was the location of the Garden of Eden; that Darwin's theory of evolution is correct, as are Donnelly's views. Atlantis was to become a theme in Russia following the 1890s, taken up in unfinished poems by Valery Bryusov and Konstantin Balmont, as well as in a drama by the schoolgirl Larissa Reisner. One other long narrative poem was published in New York by George V. Golokhvastoff. His 250-page The Fall of Atlantis (1938) records how a high priest, distressed by the prevailing degeneracy of the ruling classes, seeks to create an androgynous being from royal twins as a means to overcome this polarity. When he is unable to control the forces unleashed by his occult ceremony, the continent is destroyed. Artistic representations Music The Spanish composer Manuel de Falla worked on a dramatic cantata based on Verdaguer's L'Atlántida, during the last 20 years of his life. The name has been affixed to symphonies by Jānis Ivanovs (Symphony 4, 1941), Richard Nanes, and Vaclav Buzek (2009). There was also the symphonic celebration of Alan Hovhaness: "Fanfare for the New Atlantis" (Op. 281, 1975). The Bohemian-American composer and arranger Vincent Frank Safranek wrote Atlantis (The Lost Continent) Suite in Four Parts; I. Nocturne and Morning Hymn of Praise, II. A Court Function, III. "I Love Thee" (The Prince and Aana), IV. The Destruction of Atlantis, for military (concert) band in 1913. The opera Der Kaiser von Atlantis (The Emperor of Atlantis) was written in 1943 by Viktor Ullmann with a libretto by Petr Kien, while they were both inmates at the Nazi concentration camp of Theresienstadt. The Nazis did not allow it to be performed, assuming the opera's reference to an Emperor of Atlantis to be a satire on Hitler. Though Ullmann and Kiel were murdered in Auschwitz, the manuscript survived and was performed for the first time in 1975 in Amsterdam. Painting and sculpture Paintings of the submersion of Atlantis are comparatively rare. In the seventeenth century there was François de Nomé's The Fall of Atlantis, which shows a tidal wave surging toward a Baroque city frontage. The style of architecture apart, it is not very different from Nicholas Roerich's The Last of Atlantis of 1928. The most dramatic depiction of the catastrophe was Léon Bakst's Ancient Terror (Terror Antiquus, 1908), although it does not name Atlantis directly. It is a mountain-top view of a rocky bay breached by the sea, which is washing inland about the tall structures of an ancient city. A streak of lightning crosses the upper half of the painting, while below it rises the impassive figure of an enigmatic goddess who holds a blue dove between her breasts. Vyacheslav Ivanov identified the subject as Atlantis in a public lecture on the painting given in 1909, the year it was first exhibited, and he has been followed by other commentators in the years since. Sculptures referencing Atlantis have often been stylized single figures. One of the earliest was Einar Jónsson's The King of Atlantis (1919–1922), now in the garden of his museum in Reykjavík. It represents a single figure, clad in a belted skirt and wearing a large triangular helmet, who sits on an ornate throne supported between two young bulls. The walking female entitled Atlantis (1946) by Ivan Meštrović was from a series inspired by ancient Greek figures with the symbolical meaning of unjustified suffering. In the case of the Brussels fountain feature known as The Man of Atlantis (2003) by the Belgian sculptor , the 4-metre tall figure wearing a diving suit steps from a plinth into the spray. It looks light-hearted but the artist's comment on it makes a serious point: "Because habitable land will be scarce, it is no longer improbable that we will return to the water in the long term. As a result, a portion of the population will mutate into fish-like creatures. Global warming and rising water levels are practical problems for the world in general and here in the Netherlands in particular". Robert Smithson's Hypothetical Continent – Map of Broken Clear Glass: Atlantis was first created as a photographical project in Loveladies, New Jersey, in 1969, and then recreated as a gallery installation of broken glass. On this he commented that he liked "landscapes that suggest prehistory", and this is borne out by the original conceptual drawing of the work that includes an inset map of the continent sited off the coast of Africa and at the straits into the Mediterranean.

Arcadius ( ; 377 – 1 May 408) was Roman emperor from 383 to his death in 408. He was the eldest son of the Augustus Theodosius I () and his first wife Aelia Flaccilla, and the brother of Honorius (). Arcadius ruled the eastern half of the empire from 395, when their father died, while Honorius ruled the west. A weak ruler, his reign was dominated by a series of powerful ministers and by his wife, Aelia Eudoxia. Early life Arcadius was born in 377 in Hispania, the eldest son of Theodosius I and Aelia Flaccilla, and brother of Honorius. On 16 January 383, his father declared the five-year-old Arcadius an Augustus and co-ruler for the eastern half of the Empire. Ten years later a corresponding declaration made Honorius Augustus of the western half. Arcadius passed his early years under the tutelage of the rhetorician Themistius and Arsenius Zonaras, a monk. Emperor Early reign Both of Theodosius' sons were young and inexperienced, susceptible to being dominated by ambitious subordinates. In 394 Arcadius briefly exercised independent power with the help of his advisors in Constantinople, when his father Theodosius went west to fight Arbogastes and Eugenius. Theodosius died on 17 January 395, and Arcadius, still aged only 17, fell under the influence of the praetorian prefect of the East, Rufinus. Honorius, aged 10, was consigned to the guardianship of the magister militum Stilicho. Rufinus ambitiously sought to marry his daughter to Arcadius and thereby gain the prestige of being the emperor's father-in-law. However, when the prefect was called away to business in Antioch (where according to Zosimus, Rufinus had Lucianus, the comes orientis, flogged to death with whips loaded with lead), Arcadius was shown a painting of Aelia Eudoxia, the daughter of the deceased Frankish magister militum per orientem, Bauto. Seeing the young emperor's interest in Eudoxia, Eutropius, the eunuch praepositus sacri cubiculi, arranged for the two to meet. Arcadius fell in love and a marriage was quickly arranged, with the ceremony performed on 27 April 395. According to Zosimus, Rufinus assumed that his daughter was still to be the bride, only discovering otherwise when the nuptial procession went to Eudoxia's residence rather than his own. The rise of Eudoxia, facilitated by a general who was a rival of Rufinus, demonstrates the shifting of the centres of power in the eastern court. Such jostling for influence over the malleable emperor would be a recurring feature of Arcadius's reign. The first crisis facing the young Arcadius was the rebellion of the Visigoths in 395, under the command of Alaric I (), who sought to take advantage of the accession of two inexperienced Roman emperors. As Alaric marched towards Constantinople, plundering Macedonia and Thrace, the eastern court could offer no response, as the majority of its army had gone to Italy with Theodosius and was now in the hands of Stilicho. Perhaps sensing an opportunity to exercise power in the eastern half of the empire as well, Stilicho declared that Theodosius had made him guardian over both his sons. He traveled eastward, ostensibly to face Alaric, leading both his own forces and the Gothic mercenaries whom Theodosius had taken west in the civil war with Eugenius. Arcadius and Rufinus felt more threatened by Stilicho than by Alaric; upon landing in Thessaly Stilicho received an imperial order to send along the eastern regiments, but himself to proceed no further. Stilicho complied, falling back to Salona while Gainas led the mercenaries to Constantinople. Arcadius and his entourage received Gainas in the Campus Martius, a parade ground adjacent to the city, on 27 November 395. There Rufinus was suddenly assassinated by the Goths, on the orders of Stilicho and possibly with the support of Eutropius. The murder certainly created an opportunity for Eutropius and for Arcadius' wife, Eudoxia, who took Rufinus' place as advisors and guardians of the emperor. While Eutropius consolidated his hold on power in the capital, the distracted government still failed to react to the presence of Alaric in Greece. At first Eutropius may have coordinated with Stilicho around the defence of Illyricum; by 397, when Stilicho personally led a blockade that compelled Alaric to retreat into Epirus, the atmosphere of the eastern court had changed. As neither Arcadius nor Eutropius was keen to have Stilicho intervening in the affairs of the eastern empire, they provided no further military aid to Stilicho, who then abandoned the blockade of the Visigoths. At Eutropius's urging, Arcadius declared Stilicho to be a hostis publicus, and came to an arrangement with Alaric, making him magister militum per Illyricum. At around the same time, the eastern court persuaded Gildo, the magister utriusque militiae per Africam, to transfer his allegiance from Honorius to Arcadius, causing relations between the two imperial courts to deteriorate further. Eutropius' influence lasted four years, during which time he sought to marginalise the military and promote the civilian offices within the bureaucracy. He brought to trial two prominent military officers, Timasius and Abundantius. He also had Arcadius introduce two administrative innovations: the running of the cursus publicus (office of postmaster general) and the office in charge of manufacturing military equipment was transferred from the praetorian prefects to the magister officiorum (master of offices). Secondly, the role that Eutropius held, the praepositus sacri cubiculi (grand chamberlain) was given the rank of illustris, and therefore equal in rank to the praetorian prefects. In the autumn of 397 he issued a law in Arcadius's name, targeting the Roman military, where any conspiracy involving soldiers or the barbarian regiments against persons holding the rank of illustris was considered to be treason, with the conspirators to be sentenced to death, and their descendants to be deprived of citizenship. In 398, Eutropius led a successful campaign against the Huns in Roman Armenia. The following year he convinced Arcadius to grant him the consulship, triggering protests across the empire. For traditionalists, the granting of the consulship to a eunuch and former slave was an insult to the Roman system and other contemporary Romans, and the western court refused to recognize him as consul. The crisis escalated when the Ostrogoths who had been settled in Asia Minor by Theodosius I revolted, demanding the removal of Eutropius. The emperor sent two forces against Tribigild, the rebel leader; the first, under an officer named Leo, was defeated. The second force was commanded by Gainas, rival of Eutropius in the Eastern court. He returned to Arcadius and argued that the Ostrogoths could not be defeated, and that it would be sensible to accede to their demand. Arcadius viewed this proposal with displeasure, but was convinced to support it by Eudoxia, who wished to take Eutropius’ place as the main influence upon the emperor. Arcadius therefore dismissed Eutropius and sent him into exile (17 August 399), before recalling him to face trial and execution during the autumn of 399. The imperial edict issued by Arcadius detailing Eutropius's banishment survives: The Emperors Arcadius and Honorius, Augusti, to Aurelian, Praetorian Prefect. We have added to our treasury all the property of Eutropius, who was formerly the Praepositus sacri cubiculi, having stripped him of his splendour, and delivered the consulate from the foul stain of his tenure, and from the recollection of his name and the base filth thereof ; so that, all his acts having been repealed, all time may be dumb concerning him ; and that the blot of our age may not appear by the mention of him ; and that those who by their valour and wounds extend the Roman borders or guard the same by equity in the maintenance of law, may not groan over the fact that the divine reward of consulship has been befouled and defiled by a filthy monster. Let him learn that he has been deprived of the rank of the patriciate and all lower dignities that he stained with the perversity of his character. That all the statues, all the images —whether of bronze or marble, or painted in colours, or of any other material used in art—we command to be abolished in all cities, towns, private and public places, that they may not, as a brand of infamy on our age, pollute the gaze of beholders. Accordingly under the conduct of faithful guards let him be taken to the island of Cyprus, whither let your sublimity know that he has been banished ; so that therein guarded with most watchful diligence he may be unable to work confusion with his mad designs. Later reign With Eutropius' fall from power, Gainas sought to take advantage of Arcadius's current predicament. He joined the rebel Ostrogoths, and, in a face to face meeting with Arcadius, forced the emperor to make him magister militum praesentalis and Consul designate for 401. Arcadius also acquiesced when Gainas asked for the dismissal of further officials, such as the urban prefect Aurelianus, as well as a place for settlement for his troops in Thrace. However, Arcadius refused to agree to Gainas's demand for an Arian church in Constantinople for his Gothic mercenaries, following the advice of John Chrysostom, the Archbishop of Constantinople. By July 400, the actions of Gainas had irritated a significant portion of the population of Constantinople to the point that a general riot broke out in the capital. Although Gainas had stationed his troops outside of the capital walls, he was either unable or unwilling to bring them into the capital when many Goths in the city were hunted down and attacked. As many as 7,000 Goths were killed in the rioting; those who took refuge in a church were stoned and burned to death, after they received the emperor's permission, nor was it condemned by the Archbishop of Constantinople, John Chrysostom. Although initially staying his hand (probably through the intervention of the new Praetorian Prefect of the East Caesarius), Gainas eventually withdrew with his Gothic mercenaries into Thrace and rebelled against Arcadius. He attempted to take his forces across the Hellespont into Asia, but was intercepted and defeated by Fravitta, another Goth who held the position of magister militum praesentalis. Following his defeat, Gainas fled to the Danube with his remaining followers, but was ultimately defeated and killed by Uldin the Hun in Thrace. With the fall of Gainas, the next conflict emerged between Eudoxia and John Chrysostom. The Archbishop was a stern, ascetic individual, who was a vocal critic of all displays of extravagant wealth. But his ire tended to focus especially on wealthy women, and their use of clothing, jewellery and makeup as being vain and frivolous. Eudoxia assumed that Chrysostom's denunciations of extravagance in feminine dress were aimed at her. As the tensions between the two escalated, Chrysostom, who felt that Eudoxia had used her imperial connections to obtain the possessions of the wife of a condemned senator, preached a sermon in 401 in which Eudoxia was openly called Jezebel, the infamous wife of the Israelite king Ahab. Eudoxia retaliated by supporting Bishop Severian of Gabala in his conflict with Chrysostom. As Chrysostom was very popular in the capital, riots erupted in favour of the Archbishop, forcing Arcadius and Eudoxia to publicly back down and beg Chrysostom to revoke Severian's excommunication. Then in 403, Eudoxia saw another chance to strike against the Archbishop, when she threw her support behind Theophilus of Alexandria who presided over a synod in 403 (the Synod of the Oak) to charge Chrysostom with heresy. Although Arcadius originally supported Chrysostom, the Archbishop's decision not to participate caused Arcadius to change his mind and support Theophilus, resulting in Chrysostom's deposition and banishment. He was called back by Arcadius almost immediately, as the people started rioting over his departure, even threatening to burn the imperial palace. There was an earthquake the night of his arrest, which Eudoxia took for a sign of God's anger, prompting her to ask Arcadius for John's reinstatement. Peace was short-lived. In September 403 a silver statue of Eudoxia was erected in the Augustaion, near the Magna Ecclesia church. Chrysostom, who was conducting a mass at the time, denounced the noisy dedication ceremonies as pagan and spoke against the Empress in harsh terms: "Again Herodias raves; again she is troubled; she dances again; and again desires to receive John's head in a charger", an allusion to the events surrounding the death of John the Baptist. This time Arcadius was unwilling to overlook the insult to his wife; a new synod was called in early 404 where Chrysostom was condemned. Arcadius hesitated until Easter to enforce the sentence, but Chrysostom refused to go, even after Arcadius sent in a squad of soldiers to escort him into exile. Arcadius procrastinated, but by 20 June 404, the emperor finally managed to get the Archbishop to submit, and he was taken away to his place of banishment, this time to Abkhazia in the Caucasus. Eudoxia did not get to enjoy her victory for long, dying later that year. Death With the death of Eudoxia, Arcadius once again fell under the domination of a member of his court, this time the competent Anthemius, the Praetorian Prefect. He would rule in Arcadius's name for the final four years of his reign, seeking to repair the harm done by his predecessors. He attempted to heal the divisions of the past decade by trying to make peace with Stilicho in the West. Stilicho, however, had lost patience with the eastern court, and in 407 encouraged Alaric and the Visigoths to seize the Praetorian prefecture of Illyricum and hand it over to the western empire. Stilicho's plan failed, and soon after, on 1 May 408, Arcadius died. He was succeeded by his young son, Theodosius. Like Constantine the Great and several of his successors, he was buried in the Church of the Holy Apostles, in a porphyry sarcophagus that was described in the 10th century by Constantine VII Porphyrogenitus in the De Ceremoniis. Character and achievements In noting the character of Arcadius, the historian J. B. Bury described him and his abilities thus: He was of short stature, of dark complexion, thin and inactive, and the dullness of his wit was betrayed by his speech and by his sleepy, drooping eyes. His mental deficiency and the weakness of his character made it inevitable that he should be governed by the strong personalities of his court. Traditional interpretations of the reign of Arcadius have revolved around his weakness as an Emperor, and the formulation of policy by prominent individuals (and the court parties that formed and regrouped round them) towards curtailing the increasing influence of barbarians in the military, which in Constantinople at this period meant the Goths. Scholars such as the historian J. B. Bury spoke of a group in Arcadius's court with Germanic interests and, opposed to them, a Roman faction. So when interpreting the revolt of Gainas and the massacre of the Goths in Constantinople in 400, the episode has been traditionally interpreted by scholars such as Otto Seeck as a violent anti-barbarian reaction that functioned to stabilize the East and prevent the rise of all powerful Romanised barbarian military leaders such as Stilicho in the West - what has been termed the victory of anti-Germanism in the eastern empire. The main source of this interpretation has been the works Synesius of Cyrene, specifically Aegyptus sive de providentia and De regno. Both works have traditionally been interpreted to support the thesis that there were anti-barbarian and pro-barbarian groups, with the Praetorian Prefect Aurelianus being the leader of the anti-barbarian faction. Recent scholarly research has revised this interpretation, and has instead favoured the interaction of personal ambition and enmities among the principal participants as being the leading cause for the court intrigue throughout Arcadius's reign. The gradual decline of the use of Gothic mercenaries in the eastern empire's armies that began in the reign of Arcadius was driven by recruitment issues, as the regions beyond the Danube were made inaccessible by the Huns, forcing the empire to seek recruitment in Asia Minor. The current consensus can be summarised by the historian Thomas S. Burns: "Despite much civilian distrust and outright hatred of the army and the barbarians in it, there were no anti-barbarian or pro-barbarian parties at the court." With respect to Arcadius himself, as emperor was more concerned with appearing to be a pious Christian than he was with political or military matters. Not being a military leader, he began to promote a new type of imperial victory through images, not via the traditional military achievements, but focusing on his piety. Arcadius's reign saw the growing push towards the outright abolishment of paganism. On 13 July 399, Arcadius issued an edict ordering that all remaining non-Christian temples should be immediately demolished. In terms of buildings and monuments, a new forum was built in the name of Arcadius, on the seventh hill of Constantinople, the Xērolophos, in which a column was begun to commemorate his 'victory' over Gainas (although the column was only completed after Arcadius' death by Theodosius II). The Pentelic marble portrait head of Arcadius (now in the Istanbul Archaeology Museum) was discovered in Istanbul close to the Forum Tauri, in June 1949, in excavating foundations for new buildings of the university at Beyazit. The neck was designed to be inserted in a torso, but no statue, base or inscription was found. The diadem is a fillet with rows of pearls along its edges and a rectangular stone set about with pearls over the young Emperor's forehead. A more nuanced assessment of Arcadius's reign was provided by Warren Treadgold: By failing to reign, Arcadius had allowed a good deal of maladministration. But by continuing to reign—so harmlessly that nobody had taken the trouble to depose him—he had maintained legal continuity during a troubled time. Arcadius had four children with Eudoxia: three daughters, Pulcheria, Arcadia and Marina, and one son, Theodosius, the future Emperor Theodosius II.

The Arabs (, DIN 31635: , Arabic pronunciation: ), also known as the Arab people (), are an ethnic group mainly inhabiting the Arab world in Western Asia and Northern Africa, which formally denotes the "Arab homeland". Moreover, a significant Arab diaspora is present in various parts of the world. According to the Abrahamic tradition, Arabs are descendants of Abraham through his son Ishmael, who was born in Canaan, a region in the Levant that is now part of Palestine and Israel. Islamic sources state that Abraham brought Hagar and Ishmael to Mecca. The 14th century Arab historian Ibn Kathir mentions that the pre-Islamic Arabs considered Ishmael as their patriarch. Arabs have been in the Fertile Crescent for thousands of years. In the 9th century BCE, the Assyrians made written references to Arabs as inhabitants of the Levant, Mesopotamia, and Arabia. Throughout the ancient Near East, Arabs established influential civilizations starting from 3000 BCE onwards, such as Dilmun, Gerrha and, Magan, playing a vital role in trade between Mesopotamia, and the Mediterranean. Other prominent tribes include Midian, ʿĀd, and Thamud mentioned in the Bible and Quran. The Amorites, likely originating from Arabia, emerged around 2100 BCE in the Levant and Mesopotamia. Around 1300 BCE, the Edomites were found adjacent to Moab in the southern Levant. Later, in 900 BCE, the Qedarites enjoyed close relations with the nearby Canaanite and Aramaean states, and their territory extended from Lower Egypt to the Southern Levant. From 1200 BCE to 110 BCE, powerful Arab kingdoms such as Saba, Lihyan, Minaean, Qataban, Hadhramaut, Awsan, and Homerite emerged in Arabia. During classical antiquity, the Nabataeans established their kingdom with Petra as the capital in 300 BCE, by 271 CE, the Palmyrene Empire with the capital Palmyra, led by Queen Zenobia, encompassed the Syria Palaestina, Arabia Petraea, and Egypt, as well as large parts of Anatolia. The Arab Itureans inhabited Lebanon, Syria, and northern Palestine (Galilee) during the Hellenistic and Roman periods. The Osroene and Hatran were Arab kingdoms in Upper Mesopotamia around 200 CE. In 164 CE, the Sasanians recognized the Arabs as "Arbayistan", meaning "land of the Arabs," as they were part of Adiabene in upper Mesopotamia. The Arab Emesenes ruled by 46 BCE Emesa (Homs), Syria. During late antiquity, the Tanukhids, Salihids, Lakhmids, Kinda, and Ghassanids were dominant Arab tribes in the Levant, Mesopotamia, and Arabia, they predominantly embraced Christianity. During the Middle Ages, Islam fostered a vast Arab union, leading to significant Arab migration from the East, extremely to North Africa, under the rule of Arab empires such as the Rashidun, Umayyad, Abbasid, and Fatimid, ultimately leading to the decline of the Byzantine and Sasanian empires. At its peak, Arab territories stretched from southern France to western China, forming one of history's largest empires. The Great Arab Revolt in the early 20th century, aided in dismantling the Ottoman Empire, ultimately leading to the formation of the Arab League on 22 March 1945, with its Charter endorsing the principle of a "unified Arab homeland". Arabs from Morocco to Iraq share a common bond based on ethnicity, language, culture, history, identity, ancestry, nationalism, geography, unity, and politics, which give the region a distinct identity and distinguish it from other parts of the Muslim world. They also have their own customs, literature, music, dance, media, food, clothing, society, sports, architecture, art and, mythology. Arabs have significantly influenced and contributed to human progress in many fields, including science, technology, philosophy, ethics, literature, politics, business, art, music, comedy, theatre, cinema, architecture, food, medicine, and religion. Before Islam, most Arabs followed polytheistic Semitic religion, while some tribes adopted Judaism or Christianity and a few individuals, known as the hanifs, followed a form of monotheism. Currently, around 93% of Arabs are Muslims, while the rest are mainly Arab Christians, as well as Arab groups of Druze and Baháʼís. Etymology The earliest documented use of the word Arab in reference to a people appears in the Kurkh Monoliths, an Akkadian-language record of the Assyrian conquest of Aram (9th century BCE). The Monoliths used the term to refer to Bedouins of the Arabian Peninsula under King Gindibu, who fought as part of a coalition opposed to Assyria. Listed among the booty captured by the army of the Assyrian king Shalmaneser III in the Battle of Qarqar (853 BCE) are 1000 camels of "Gîndibuʾ the Arbâya" or "[the man] Gindibu belonging to the Arabs" (ar-ba-a-a being an adjectival nisba of the noun ʿArab). The related word ʾaʿrāb is used to refer to Bedouins today, in contrast to ʿArab which refers to Arabs in general. Both terms are mentioned around 40 times in pre-Islamic Sabaean inscriptions. The term ʿarab ('Arab') occurs also in the titles of the Himyarite kings from the time of 'Abu Karab Asad until MadiKarib Ya'fur. According to Sabaean grammar, the term ʾaʿrāb is derived from the term ʿarab. The term is also mentioned in Quranic verses, referring to people who were living in Madina and it might be a south Arabian loanword into Quranic language. The oldest surviving indication of an Arab national identity is an inscription made in an archaic form of Arabic in 328 CE using the Nabataean alphabet, which refers to Imru' al-Qays ibn 'Amr as 'King of all the Arabs'. Herodotus refers to the Arabs in the Sinai, southern Palestine, and the frankincense region (Southern Arabia). Other Ancient-Greek historians like Agatharchides, Diodorus Siculus and Strabo mention Arabs living in Mesopotamia (along the Euphrates), in Egypt (the Sinai and the Red Sea), southern Jordan (the Nabataeans), the Syrian steppe and in eastern Arabia (the people of Gerrha). Inscriptions dating to the 6th century BCE in Yemen include the term 'Arab'. The most popular Arab account holds that the word Arab came from an eponymous father named Ya'rub, who was supposedly the first to speak Arabic. Abu Muhammad al-Hasan al-Hamdani had another view; he states that Arabs were called gharab ('westerners') by Mesopotamians because Bedouins originally resided to the west of Mesopotamia; the term was then corrupted into Arab. Yet another view is held by al-Masudi that the word Arab was initially applied to the Ishmaelites of the Arabah valley. In Biblical etymology, Arab (Hebrew: arvi) comes from the desert origin of the Bedouins it originally described (arava means 'wilderness'). The root ʿ-r-b has several additional meanings in Semitic languages—including 'west, sunset', 'desert', 'mingle', 'mixed', 'merchant' and 'raven'—and are "comprehensible" with all of these having varying degrees of relevance to the emergence of the name. It is also possible that some forms were metathetical from , 'moving around' (Arabic: , 'traverse') and hence, it is alleged, 'nomadic'. Origins Arabic is a Semitic language that belongs to the Afroasiatic language family. The majority of scholars accept the "Arabian peninsula" has long been accepted as the original Urheimat (linguistic homeland) of the Semitic languages. Or to be from the Levant. The ancient Semitic-speaking peoples lived in the ancient Near East, including the Levant, Mesopotamia, and the Arabian Peninsula from the 3rd millennium BCE to the end of antiquity. Proto-Semitic likely reached the Arabian Peninsula by the 4th millennium BCE, and its daughter languages spread outward from there, while Old Arabic began to differentiate from Central Semitic by the start of the 1st millennium BCE. Central Semitic is a branch of the Semitic language includes Arabic, Aramaic, Canaanite, Phoenician, Hebrew and others. The origins of Proto-Semitic may lie in the Arabian Peninsula, with the language spreading from there to other regions. This theory proposes that Semitic peoples reached Mesopotamia and other areas from the deserts to the west, such as the Akkadians who entered Mesopotamia around the late 4th millennium BCE. The origins of Semitic peoples are thought to include various regions Mesopotamia, the Levant, the Arabian Peninsula, and North Africa. Some view that Semitic may have originated in the Levant around 3800 BCE and subsequently spread to the Horn of Africa around 800 BCE from Arabia, as well as to North Africa. According to Arab-Islamic-Jewish traditions, Ishmael son of Abraham was "father of the Arabs", to be the ancestor of the Arabs. That Abraham be the ancestor of the Arabs and Israelites. Shem's descendants: Genesis chapter 10 verses 21–30 gives one list of descendants of Shem. In chapter 11 verses 10–26 a second list of descendants of Shem names Abraham and thus the Arabs and Israelites. Genetic research has indicated that Arabs and Jews share common genetic ancestry and are closely related. Additionally, it is common for Arabs and Jews to refer to each other as "cousins". The Book of Genesis narrates that God promised Hagar to beget from Ishmael twelve princes and turn him to a "great nation". Ya'rub is the grandson of Abir being the son of Qahtan/Joktan is an ancestor of the Ishmaelites and the Israelites according to the "Table of Nations" in the Book of Genesis () and the Books of Chronicles (). Qahtan/Joktan mentioned in the Hebrew Bible, he descends from Shem, son of Noah. Joktan's sons in the order provided in , were Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab. Keturah was a wife of Abraham, according to the Book of Genesis, Abraham married Keturah after the death of his first wife, Sarah. Abraham and Keturah had six sons: Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Genesis and First Chronicles also list seven of her grandsons (Sheba, Dedan, Ephah, Epher, Hanoch, Abida, and Eldaah). Keturah's sons were to have represented the Arab tribes who lived south and east of Palestine (). Ishmael was considered the ancestor of Muhammad the founder of Islam, was linked to him through the lineage of the patriarch Adnan. Ishmael also has been claimed as the ancestor of the Southern Arabs through his descendant Qahtan. "Zayd ibn Amr" was another Pre-Islamic figure who refused idolatry and preached monotheism, claiming it was the original belief of their [Arabs] father Ishmael. The tribes of Central West Arabia called themselves the "people of Abraham and the offspring of Ishmael." Ibn Khaldun an Arab scholar in the 8th century described the Arabs were divided into two groups: ‘Adnan and Qahtan, both of which were attributed to Ishmaelite origins. He provided a definition of who the Arabs were, stating that they were a large nation occupying territories from the Atlantic Ocean (Maghreb) in the West (Mashriq) to Yemen and the Indian border in the East. According to him, most Arabs descending from the Qudā‘a, Qahtan, and ‘Adnan tribes (Ishmaelite). The Hebrew Bible occasionally refers to Aravi peoples (or variants thereof), translated as "Arab". The scope of the term at that early stage is unclear, but it seems to have referred to various desert-dwelling Semitic tribes in the Levant and Arabia. And the Book of Jubilees claims that the sons of Ishmael intermingled with the 6 sons of Keturah, from Abraham, and their descendants were called Arabs and Ishmaelites: "And Ishmael and his sons, and the sons of Keturah and their sons, went together and dwelt from Paran to the entering in of Babylon in all the land towards the East facing the desert. And these mingled with each other, and their name was called Arabs, and Ishmaelites". The Biblical texts mention Ishmael, son of Abraham, as the ancestor of twelve nomadic tribes who settled in the desert lands between North Arabia, Egypt, and Palestine (Genesis 25:13-16). The Ishmaelites denoted a broad confederation of people, including sub-groups such as the Midianites, Amalekites, and Hagarites (Genesis 37:25, 27; 39:1). Chapter 25 lists his sons as: And these are the names of the sons of Ishmael, by their names, according to their generations: the firstborn of Ishmael Nebaioth; and Kedar, and Adbeel, and Mibsam, And Mishma, and Dumah, and Massa, Hadar, and Tema, Jetur, Naphish, and Kedemah. The Bible also mentions "Arabs" or "Arabians" as nomads wandering in North Arabia and Southern Palestine, with some verses associating them with animal-breeding, such as the tribute of flocks, rams, and goats brought to Jehoshaphat by the Arabs.The Quran mention, Ibrahim (Abraham) and his wife Hajar (Hagar) bore a prophetic child named Ishmael, who was gifted by God all of Ishmael, Alyasa, Yunus and Lut a favor above the nations. God ordered Ibrahim to bring Hajar and Ishmael to Mecca, where he prayed for them to be provided with water and fruits. Hajar ran between the hills of Safa and Marwa in search of water, and an angel appeared to them and provided them with water. Ishmael grew up in Mecca. Ibrahim was later ordered to sacrifice Ishmael in a dream, but God intervened and replaced him with a goat. Ibrahim and Ishmael then built the Kaaba in Mecca, which was originally constructed by Adam. The Quran calls itself , "Arabic", and , "clear". According to the Samaritan book Asaṭīr adds: "And after the death of Abraham, Ishmael reigned twenty-seven years; And all the children of Nebaot ruled for one year in the lifetime of Ishmael; And for thirty years after his death from the river of Egypt to the river Euphrates; and they built Mecca." Josephus also lists the sons and states that they "...inhabit the lands which are between Euphrates and the Red Sea, the name of which country is Nabathæa. The Targum Onkelos annotates (Genesis 25:16), describing the extent of their settlements: The Ishmaelites lived from Hindekaia (India) to Chalutsa (possibly in Arabia), by the side of Mizraim (Egypt), and from the area around Arthur (Assyria) up towards the north. This description suggests that the Ishmaelites were a widely dispersed group with a presence across a significant portion of the ancient Near East. History The nomads of Arabia have been spreading through the desert fringes of the Fertile Crescent since at least 3000 BCE, but the first known reference to the Arabs as a distinct group is from an Assyrian scribe recording a battle in 853 BCE. The history of the Arabs during the pre-Islamic period in various regions, including Arabia, Levant, Mesopotamia, and Egypt. The Arabs were mentioned by their neighbors, such as Assyrian and Babylonian Royal Inscriptions from 9th to 6th century BCE, mention the king of Qedar as king of the Arabs and King of the Ishmaelites. Of the names of the sons of Ishmael the names "Nabat, Kedar, Abdeel, Dumah, Massa, and Teman" were mentioned in the Assyrian Royal Inscriptions as tribes of the Ishmaelites. Jesur was mentioned in Greek inscriptions in the 1st century BCE. There are also records from Sargon's reign that mention sellers of iron to people called Arabs in Ḫuzaza in Babylon, causing Sargon to prohibit such trade out of fear that the Arabs might use the resource to manufacture weapons against the Assyrian army. The history of the Arabs in relation to the Bible shows that they were a significant part of the region and played a role in the lives of the Israelites. The study asserts that the Arab nation is an ancient and significant entity; however, it highlights that the Arabs lacked a collective awareness of their unity. They did not inscribe their identity as Arabs or assert exclusive ownership over specific territories. Magan, Midian, and ʿĀd are all ancient tribes or civilizations that are mentioned in Arabic literature and have roots in the Arabia. Magan (, ), known for its production of copper and other metals, the region was an important trading center in ancient times and is mentioned in the Qur'an as a place where the prophet Moses traveled during his lifetime. Midian (, ), on the other hand, was a region located in the northwestern part of the Arabia, the people of Midian are mentioned in the Qur'an as having worshiped idols and having been punished by God for their disobedience. The prophet Moses also lived in Midian for a time, where he married and worked as a shepherd. ʿĀd (, ), as mentioned earlier, was an ancient tribe that lived in the southern Arabia, the tribe was known for its wealth, power, and advanced technology, but they were ultimately destroyed by a powerful windstorm as punishment for their disobedience to God. ʿĀd is regarded as one of the original Arab tribes. The historian Herodotus provided extensive information about Arabia, describing the spices, terrain, folklore, trade, clothing, and weapons of the Arabs. In his third book, he mentioned the Arabs (Άραβες) as a force to be reckoned with in the north of the Arabian Peninsula just before Cambyses’ campaign against Egypt. Other Greek and Latin authors who wrote about Arabia include Theophrastus, Strabo, Diodorus Siculus, and Pliny the Elder. The Jewish historian Flavius Josephus wrote about the Arabs and their king, mentioning their relationship with Cleopatra, the queen of Egypt. The tribute paid by the Arab king to Cleopatra was collected by Herod, the king of the Jews, but the Arab king later became slow in his payments and refused to pay without further deductions. This sheds some light on the relations between the Arabs, Jews, and Egypt at that time. Geshem the Arab was an Arab man who opposed Nehemiah in the Hebrew Bible (Neh. 2:19, 6:1). He was likely the chief of the Arab tribe "Gushamu" and have been a powerful ruler with influence stretching from northern Arabia to Judah. The Arabs and the Samaritans made efforts to hinder Nehemiah's rebuilding of the walls of Jerusalem. The term "Saracens" was a term used in the early centuries, both in Greek and Latin writings, to refer to the "Arabs" who lived in and near what was designated by the Romans as Arabia Petraea (Levant) and Arabia Deserta (Arabia). The Christians of Iberia used the term Moor to describe all the Arabs and Muslims of that time. Arabs of Medina referred to the nomadic tribes of the deserts as the A'raab, and considered themselves sedentary, but were aware of their close racial bonds. Hagarenes is a term widely used by early Syriac, Greek, and Armenian to describe the early Arab conquerors of Mesopotamia, Syria and Egypt, refers to the descendants of Hagar, who bore a son named Ishmael to Abraham in the Old Testament. In the Bible, the Hagarenes referred to as "Ishmaelites" or "Arabs." The Arab conquests in the 7th century was a sudden and dramatic conquest led by Arab armies, which quickly conquered much of the Middle East, North Africa, and Spain. It was a significant moment for Islam, which saw itself as the successor of Judaism and Christianity. The term ʾiʿrāb has the same root refers to the Bedouin tribes of the desert who rejected Islam and resisted Muhammad.(Quran 9:97) The 14th century Kebra Nagast says "And therefore the children of Ishmael became kings over Tereb, and over Kebet, and over Nôbâ, and Sôba, and Kuergue, and Kîfî, and Mâkâ, and Môrnâ, and Fînḳânâ, and ’Arsîbânâ, and Lîbâ, and Mase'a, for they were the seed of Shem." Antiquity Limited local historical coverage of these civilizations means that archaeological evidence, foreign accounts and Arab oral traditions are largely relied on to reconstruct this period. Prominent civilizations at the time included, Dilmun civilization was an important trading centre which at the height of its power controlled the Arabian Gulf trading routes. The Sumerians regarded Dilmun as holy land. Dilmun is regarded as one of the oldest ancient civilizations in the Middle East. which arose around the 4th millennium BCE and lasted to 538 BCE. Gerrha was an ancient city of Eastern Arabia, on the west side of the Gulf, Gerrha was the center of an Arab kingdom from approximately 650 BCE to circa CE 300. Thamud, which arose around the 1st millennium BCE and lasted to about 300 CE. From the beginning of the first millennium BCE, Proto-Arabic, or Ancient North Arabian, texts give a clearer picture of the Arabs' emergence. The earliest are written in variants of epigraphic south Arabian musnad script, including the 8th century BCE Hasaean inscriptions of eastern Saudi Arabia, the Thamudic texts found throughout the Arabian Peninsula and Sinai. The Qedarites were a largely nomadic ancient Arab tribal confederation centred in the Wādī Sirḥān in the Syrian Desert. They were known for their nomadic lifestyle and for their role in the caravan trade that linked the Arabian Peninsula with the Mediterranean world. The Qedarites gradually expanded their territory over the course of the 8th and 7th centuries BCE, and by the 6th century BCE, they had consolidated into a kingdom that covered a large area in northern Arabia, southern Palestine, and the Sinai Peninsula. The Qedarites were influential in the ancient Near East, and their kingdom played a significant role in the political and economic affairs of the region for several centuries. Sheba ( Saba) is kingdom mentioned in the Hebrew Bible (Old Testament) and the Quran. Sheba features in Jewish, Muslim, and Christian traditions, whose lineage goes back to Qahtan son of Hud, one of the ancestors of the Arabs, Sheba was mentioned in Assyrian inscriptions and in the writings of Greek and Roman writers. One of the ancient written references that also spoke of Sheba is the Old Testament, which stated that the people of Sheba supplied Syria and Egypt with incense, especially frankincense, and exported gold and precious stones to them. The Queen of Sheba who travelled to Jerusalem to question King Solomon, great caravan of camels, carrying gifts of gold, precious stones, and spices, when she arrived, she was impressed by the wisdom and wealth of King Solomon, and she posed a series of difficult questions to him. King Solomon was able to answer all of her questions, and the Queen of Sheba was impressed by his wisdom and his wealth.()Sabaeans are mentioned several times in the Hebrew Bible. In the Quran, they are described as either (, not to be confused with , ), or as (). They were known for their prosperous trade and agricultural economy, which was based on the cultivation of frankincense and myrrh, these highly valued aromatic resins were exported to Egypt, Greece, and Rome, making the Sabaeans wealthy and powerful, they also traded in spices, textiles, and other luxury goods. The Maʾrib Dam was one of the greatest engineering achievements of the ancient world, and it provided water for the city of Maʾrib and the surrounding agricultural lands. Lihyan also called Dadān or Dedan was a powerful and highly organized ancient Arab kingdom that played a vital cultural and economic role in the north-western region of the Arabian Peninsula and used Dadanitic language. The Lihyanites were known for their advanced organization and governance, and they played a significant role in the cultural and economic life of the region. The kingdom was centered around the city of Dedan (modern-day Al Ula), and it controlled a large territory that extended from Yathrib in the south to parts of the Levant in the north. The Arab genealogies consider the Banu Lihyan to be Ishmaelites, and used Dadanitic language. The Kingdom of Ma'in was an ancient Arab kingdom with a hereditary monarchy system and a focus on agriculture and trade. Proposed dates range from the 15th century BCE to the 1st century CE Its history has been recorded through inscriptions and classical Greek and Roman books, although the exact start and end dates of the kingdom are still debated. The Ma'in people had a local governance system with councils called "Mazood," and each city had its own temple that housed one or more gods. They also adopted the Phoenician alphabet and used it to write their language. The kingdom eventually fell to the Arab Sabaean people.Qataban was an ancient kingdom located in the South Arabia, which existed from the early 1st millennium BCE till the late 1st or 2nd centuries CE. It developed into a centralized state in the 6th century BCE with two co-kings ruling poles. Qataban expanded its territory, including the conquest of Ma'in and successful campaigns against the Sabaeans. It challenged the supremacy of the Sabaeans in the region and waged a successful war against Hadramawt in the 3rd century BCE. Qataban's power declined in the following centuries, leading to its annexation by Hadramawt and Ḥimyar in the 1st century CE. The Kingdom of Hadhramaut it was known for its rich cultural heritage, as well as its strategic location along important trade routes that connected the Middle East, South Asia, and East Africa. The Kingdom was established around the 3rd century BCE, and it reached its peak during the 2nd century CE, when it controlled much of the southern Arabian Peninsula. The kingdom was known for its impressive architecture, particularly its distinctive towers, which were used as watchtowers, defensive structures, and homes for wealthy families. The people of Hadhramaut were skilled in agriculture, especially in growing frankincense and myrrh. They had a strong maritime culture and traded with India, East Africa, and Southeast Asia. Although the kingdom declined in the 4th century, Hadhramaut remained a cultural and economic center. Its legacy can still be seen today. The ancient Kingdom of Awsān (8th century BCE–7th century BCE) was indeed one of the most important small kingdoms of South Arabia, and its capital Ḥajar Yaḥirr was a significant center of trade and commerce in the ancient world. It is fascinating to learn about the rich history of this region and the cultural heritage that has been preserved through the archaeological sites like Ḥajar Asfal. The destruction of the city in the 7th century BCE by the king and Mukarrib of Saba' Karab El Watar is a significant event in the history of South Arabia. It highlights the complex political and social dynamics that characterized the region at the time and the power struggles between different kingdoms and rulers. The victory of the Sabaeans over Awsān is also a testament to the military might and strategic prowess of the Sabaeans, who were one of the most powerful and influential kingdoms in the region. The Himyarite Kingdom or Himyar, was an ancient kingdom that existed from around the 2nd century BCE to the 6th century CE. It was centered in the city of Zafar, which is located in present-day Yemen. The Himyarites were a Arab people who spoke a South Arabian language and were known for their prowess in trade and seafaring, they controlled the southern part of Arabia and had a prosperous economy based on agriculture, commerce, and maritime trade, they were skilled in irrigation and terracing, which allowed them to cultivate crops in the arid environment. The Himyarites converted to Judaism in the 4th century CE, and their rulers became known as the "Kings of the Jews", this conversion was likely influenced by their trade connections with the Jewish communities of the Red Sea region and the Levant, however, the Himyarites also tolerated other religions, including Christianity and the local pagan religions. Classical antiquity The Nabataeans were nomadic Arabs who moved into territory vacated by the Edomites– Semites who settled the region centuries before them. Their early inscriptions were in Aramaic, but gradually switched to Arabic, and since they had writing, it was they who made the first inscriptions in Arabic. The Nabataean alphabet was adopted by Arabs to the south, and evolved into modern Arabic script around the 4th century. This is attested by Safaitic inscriptions (beginning in the 1st century BCE) and the many Arabic personal names in Nabataean inscriptions. From about the 2nd century BCE, a few inscriptions from Qaryat al-Faw reveal a dialect no longer considered proto-Arabic, but pre-classical Arabic. Five Syriac inscriptions mentioning Arabs have been found at Sumatar Harabesi, one of which dates to the 2nd century CE. Arabs are first recorded in Palmyra in the late first millennium BCE. The soldiers of the sheikh Zabdibel, who aided the Seleucids in the battle of Raphia (217 BCE), were described as Arabs; Zabdibel and his men were not actually identified as Palmyrenes in the texts, but the name "Zabdibel" is a Palmyrene name leading to the conclusion that the sheikh hailed from Palmyra. After the Battle of Edessa in 260 CE. Valerian's capture by the Sassanian king Shapur I was a significant blow to Rome, and it left the empire vulnerable to further attacks. Zenobia was able to capture most of the Near East, including Egypt and parts of Asia Minor. However, their empire was short-lived, as Aurelian was able to defeat the Palmyrenes and recover the lost territories. The Palmyrenes were helped by their Arab allies, but Aurelian was also able to leverage his own alliances to defeat Zenobia and her army. Ultimately, the Palmyrene Empire lasted only a few years, but it had a significant impact on the history of the Roman Empire and the Near East. The Itureans were an Arab people who inhabited the region of Iturea, emerged as a prominent power in the region after the decline of the Seleucid Empire in the 2nd century BCE, from their base around Mount Lebanon and the Beqaa Valley, they came to dominate vast stretches of Syrian territory, and appear to have penetrated into northern parts of Palestine as far as the Galilee. Tanukhids were an Arab tribal confederation that lived in the central and eastern Arabian Peninsula during the late ancient and early medieval periods. As mentioned earlier, they were a branch of the Rabi'ah tribe, which was one of the largest Arab tribes in the pre-Islamic period. They were known for their military prowess and played a significant role in the early Islamic period, fighting in battles against the Byzantine and Sassanian empires and contributing to the expansion of the Arab empire. The Osroene Arabs, also known as the Abgarids, were in possession of the city of Edessa in the ancient Near East for a significant period of time. Edessa was located in the region of Osroene, which was an ancient kingdom that existed from the 2nd century BCE to the 3rd century CE. They established a dynasty known as the Abgarids, which ruled Edessa for several centuries. The most famous ruler of the dynasty was Abgar V, who is said to have corresponded with Jesus Christ and is believed to have converted to Christianity. The Abgarids played an important role in the early history of Christianity in the region, and Edessa became a center of Christian learning and scholarship. The Kingdom of Hatra was an ancient city located in the region of Mesopotamia, it was founded in the 2nd or 3rd century BCE and flourished as a major center of trade and culture during the Parthian Empire. The rulers of Hatra were known as the Arsacid dynasty, which was a branch of the Parthian ruling family. However, in the 2nd century CE, the Arab tribe of Banu Tanukh seized control of Hatra and established their own dynasty. The Arab rulers of Hatra assumed the title of "malka," which means king in Arabic, and they often referred to themselves as the "King of the Arabs." The Osroeni and Hatrans were part of several Arab groups or communities in upper Mesopotamia, who also included the Praetavi of Singara reported by Pliny the Elder, and the Arabs of Adiabene which was an ancient kingdom in northern Mesopotamia, its chief city was Arbela (Arba-ilu), where Mar Uqba had a school, or the neighboring Hazzah, by which name the later Arabs also called Arbela. This elaborate Arab presence in upper Mesopotamia was acknowledged by the Sasanians, who called the region Arbayistan, meaning "land of the Arabs", is first attested as a province in the Ka'ba-ye Zartosht inscription of the second Sasanian King of Kings (shahanshah) Shapur I (), which was erected in 262. The Emesene were a dynasty of Arab priest-kings that ruled the city of Emesa (modern-day Homs, Syria) in the Roman province of Syria from the 1st century CE to the 3rd century CE. The dynasty is notable for producing a number of high priests of the god El-Gabal, who were also influential in Roman politics and culture. The first ruler of the Emesene dynasty was Sampsiceramus I, who came to power in 64 CE. He was succeeded by his son, Iamblichus, who was followed by his own son, Sampsiceramus II. Under Sampsiceramus II, Emesa became a client kingdom of the Roman Empire, and the dynasty became more closely tied to Roman political and cultural traditions. Late antiquity The Ghassanids, Lakhmids and Kindites were the last major migration of pre-Islamic Arabs out of Yemen to the north. The Ghassanids increased the Semitic presence in then-Hellenized Syria, the majority of Semites were Aramaic peoples. They mainly settled in the Hauran region and spread to modern Lebanon, Palestine and Jordan. Greeks and Romans referred to all the nomadic population of the desert in the Near East as Arabi. The Romans called Yemen "Arabia Felix". The Romans called the vassal nomadic states within the Roman Empire Arabia Petraea, after the city of Petra, and called unconquered deserts bordering the empire to the south and east Arabia Magna. The Lakhmids as a dynasty inherited their power from the Tanukhids, the mid Tigris region around their capital Al-Hira. They ended up allying with the Sassanids against the Ghassanids and the Byzantine Empire. The Lakhmids contested control of the Central Arabian tribes with the Kindites with the Lakhmids eventually destroying the Kingdom of Kinda in 540 after the fall of their main ally Himyar. The Persian Sassanids dissolved the Lakhmid dynasty in 602, being under puppet kings, then under their direct control. The Kindites migrated from Yemen along with the Ghassanids and Lakhmids, but were turned back in Bahrain by the Abdul Qais Rabi'a tribe. They returned to Yemen and allied themselves with the Himyarites who installed them as a vassal kingdom that ruled Central Arabia from "Qaryah Dhat Kahl" (the present-day called Qaryat al-Faw). They ruled much of the Northern/Central Arabian peninsula, until they were destroyed by the Lakhmid king Al-Mundhir, and his son 'Amr. The Ghassanids were an Arab tribe in the Levant in the early third century. According to Arab genealogical tradition, they were considered a branch of the Azd tribe. They fought alongside the Byzantines against the Sasanians and Arab Lakhmids. Most Ghassanids were Christians, converting to Christianity in the first few centuries, and some merged with Hellenized Christian communities. After the Muslim conquest of the Levant, few Ghassanids became Muslims, and most remained Christian and joined Melkite and Syriac communities within what is now Jordan, Palestine, Syria, and Lebanon. The Salihids were Arab foederati in the 5th century, were ardent Christians, and their period is less documented than the preceding and succeeding periods due to a scarcity of sources. Most references to the Salihids in Arabic sources derive from the work of Hisham ibn al-Kalbi, with the Tarikh of Ya'qubi considered valuable for determining the Salihids' fall and the terms of their foedus with the Byzantines. Middle Ages During the Middle Ages, Arab civilization flourished and the Arabs made significant contributions to the fields of science, mathematics, medicine, philosophy, and literature, with the rise of great cities like Baghdad, Cairo, and Cordoba, they became centers of learning, attracting scholars, scientists, and intellectuals. Arabs forged many empires and dynasties, most notably, the Rashidun Empire, the Umayyad Empire, the Abbasid Empire, the Fatimid Empire, among others. These empires were characterized by their expansion, scientific achievements, and cultural flourishing, extended from Spain to India The Arabs during the Middle Ages was a vibrant and dynamic region that left a lasting impact on the world.The rise of Islam began when Muhammad and his followers migrated from Mecca to Medina in an event known as the Hijra. Muhammad spent the last ten years of his life engaged in a series of battles to establish and expand the Muslim community. From 622 to 632, he led the Muslims in a state of war against the Meccans. During this period, the Arabs conquered the region of Basra, and under the leadership of Umar, they established a base and built a mosque there. Another conquest was Midian, but due to its harsh environment, the settlers eventually moved to Kufa. Umar successfully defeated rebellions by various Arab tribes, bringing stability to the entire Arabian peninsula and unifying it. Under the leadership of Uthman, the Arab empire expanded through the conquest of Persia, with the capture of Fars in 650 and parts of Khorasan in 651. The conquest of Armenia also began in the 640s. During this time, the Rashidun Empire extended its rule over the entire Sassanid Empire and more than two-thirds of the Eastern Roman Empire. However, the reign of Ali ibn Abi Talib, the fourth caliph, was marred by the First Fitna, or the First Islamic Civil War, which lasted throughout his rule. After a peace treaty with Hassan ibn Ali and the suppression of early Kharijite disturbances, Muawiyah I became the Caliph. This marked a significant transition in leadership. Arab empires Rashidun era (632–661) After the death of Muhammad in 632, Rashidun armies launched campaigns of conquest, establishing the Caliphate, or Islamic Empire, one of the largest empires in history. It was larger and lasted longer than the previous Arab empire Tanukhids of Queen Mawia or the Arab Palmyrene Empire. The Rashidun state was a completely new state and unlike the Arab kingdoms of its century such as the Himyarite, Lakhmids or Ghassanids. During the Rashidun era, the Arab community expanded rapidly, conquering many territories and establishing a vast Arab empire, which is marked by the reign of the first four caliphs, or leaders, of the Arab community. These caliphs are Abu Bakr, Umar, Uthman and Ali, who are collectively known as the Rashidun, meaning "rightly guided." The Rashidun era is significant in Arab and Islamic history as it marks the beginning of the Arab empire and the spread of Islam beyond the Arabian Peninsula. During this time, the Arab community faced numerous challenges, including internal divisions and external threats from neighboring empires. Under the leadership of Abu Bakr, the Arab community successfully quelled a rebellion by some tribes who refused to pay Zakat, or Islamic charity. During the reign of Umar ibn al-Khattab, the Arab empire expanded significantly, conquering territories such as Egypt, Syria, and Iraq. The reign of Uthman ibn Affan was marked by internal dissent and rebellion, which ultimately led to his assassination. Ali, the cousin and son-in-law of the Prophet Muhammad, succeeded Uthman as caliph but faced opposition from some members of the Islamic community who believed he was not rightfully appointed. Despite these challenges, the Rashidun era is remembered as a time of great progress and achievement in Arab and Islamic history, the caliphs established a system of governance that emphasized justice and equality for all members of the Islamic community. They also oversaw the compilation of the Quran into a single text and spread Arabic teachings and principles throughout the empire. Overall, the Rashidun era played a crucial role in shaping Arab history and continues to be revered by Muslims worldwide as a period of exemplary leadership and guidance. Umayyad era (661–750 & 756–1031) In 661, the Rashidun Caliphate fell into the hands of the Umayyad dynasty and Damascus was established as the empire's capital. The Umayyads were proud of their Arab identity and sponsored the poetry and culture of pre-Islamic Arabia. They established garrison towns at Ramla, Raqqa, Basra, Kufa, Mosul and Samarra, all of which developed into major cities. Caliph Abd al-Malik established Arabic as the Caliphate's official language in 686. Caliph Umar II strove to resolve the conflict when he came to power in 717. He rectified the disparity, demanding that all Muslims be treated as equals, but his intended reforms did not take effect, as he died after only three years of rule. By now, discontent with the Umayyads swept the region and an uprising occurred in which the Abbasids came to power and moved the capital to Baghdad. Umayyads expanded their Empire westwards capturing North Africa from the Byzantines. Before the Arab conquest, North Africa was conquered or settled by various people including Punics, Vandals and Romans. After the Abbasid Revolution, the Umayyads lost most of their territories with the exception of Iberia. Their last holding became known as the Emirate of Córdoba. It was not until the rule of the grandson of the founder of this new emirate that the state entered a new phase as the Caliphate of Córdoba. This new state was characterized by an expansion of trade, culture and knowledge, and saw the construction of masterpieces of al-Andalus architecture and the library of Al-Ḥakam II which housed over 400,000 volumes. With the collapse of the Umayyad state in 1031 CE, Al-Andalus was divided into small kingdoms. Abbasid era (750–1258 & 1261–1517) The Abbasids were the descendants of Abbas ibn Abd al-Muttalib, one of the youngest uncles of Muhammad and of the same Banu Hashim clan. The Abbasids led a revolt against the Umayyads and defeated them in the Battle of the Zab effectively ending their rule in all parts of the Empire with the exception of al-Andalus. In 762, the second Abbasid Caliph al-Mansur founded the city of Baghdad and declared it the capital of the Caliphate. Unlike the Umayyads, the Abbasids had the support of non-Arab subjects. The Islamic Golden Age was inaugurated by the middle of the 8th century by the ascension of the Abbasid Caliphate and the transfer of the capital from Damascus to the newly founded city of Baghdad. The Abbasids were influenced by the Quranic injunctions and hadith such as "The ink of the scholar is more holy than the blood of martyrs" stressing the value of knowledge. During this period the Arab Empire became an intellectual centre for science, philosophy, medicine and education as the Abbasids championed the cause of knowledge and established the "House of Wisdom" () in Baghdad. Rival dynasties such as the Fatimids of Egypt and the Umayyads of al-Andalus were also major intellectual centres with cities such as Cairo and Córdoba rivaling Baghdad. The Abbasids ruled for 200 years before they lost their central control when Wilayas began to fracture in the 10th century; afterwards, in the 1190s, there was a revival of their power, which was ended by the Mongols, who conquered Baghdad in 1258 and killed the Caliph Al-Musta'sim. Members of the Abbasid royal family escaped the massacre and resorted to Cairo, which had broken from the Abbasid rule two years earlier; the Mamluk generals taking the political side of the kingdom while Abbasid Caliphs were engaged in civil activities and continued patronizing science, arts and literature. Fatimid era (909–1171) The Fatimid caliphate was founded by al-Mahdi Billah, a descendant of Fatimah, the daughter of Muhammad, the Fatimid Caliphate was a Shia that existed from 909 to 1171 CE. The empire was based in North Africa, with its capital in Cairo, and at its height, it controlled a vast territory that included parts of modern-day Egypt, Libya, Tunisia, Algeria, Morocco, Syria, and Palestine. The Fatimid state took shape among the Kutama, in the West of the North African littoral, in Algeria, in 909 conquering Raqqada, the Aghlabid capital. In 921 the Fatimids established the Tunisian city of Mahdia as their new capital. In 948 they shifted their capital to Al-Mansuriya, near Kairouan in Tunisia, and in 969 they conquered Egypt and established Cairo as the capital of their caliphate. The Fatimids were known for their religious tolerance and intellectual achievements, they established a network of universities and libraries that became centers of learning in the Islamic world. They also promoted the arts, architecture, and literature, which flourished under their patronage. One of the most notable achievements of the Fatimids was the construction of the Al-Azhar Mosque and Al-Azhar University in Cairo. Founded in 970 CE, it is one of the oldest universities in the world and remains an important center of Islamic learning to this day. The Fatimids also had a significant impact on the development of Islamic theology and jurisprudence. They were known for their support of Shia Islam and their promotion of the Ismaili branch of Shia Islam. Despite their many achievements, the Fatimids faced numerous challenges during their reign. They were constantly at war with neighboring empires, including the Abbasid Caliphate and the Byzantine Empire. They also faced internal conflicts and rebellions, which weakened their empire over time. In 1171 CE, the Fatimid Caliphate was conquered by the Ayyubid dynasty, led by Saladin. Although the Fatimid dynasty came to an end, its legacy continued to influence Arab-Islamic culture and society for centuries to come. Ottoman era (1517–1918) From 1517 to 1918, The Ottomans defeated the Mamluk Sultanate in Cairo, and ended the Abbasid Caliphate in the battles of Marj Dabiq and Ridaniya. They entered the Levant and Egypt as conquerors, and brought down the Abbasid caliphate after it lasted for many centuries. In 1911, Arab intellectuals and politicians from throughout the Levant formed al-Fatat ("the Young Arab Society"), a small Arab nationalist club, in Paris. Its stated aim was "raising the level of the Arab nation to the level of modern nations." In the first few years of its existence, al-Fatat called for greater autonomy within a unified Ottoman state rather than Arab independence from the empire. Al-Fatat hosted the Arab Congress of 1913 in Paris, the purpose of which was to discuss desired reforms with other dissenting individuals from the Arab world. However, as the Ottoman authorities cracked down on the organization's activities and members, al-Fatat went underground and demanded the complete independence and unity of the Arab provinces. The Arab Revolt was a military uprising of Arab forces against the Ottoman Empire during World War I, began in 1916, led by Sherif Hussein bin Ali, the goal of the revolt was to gain independence for the Arab lands under Ottoman rule and to create a unified Arab state. The revolt was sparked by a number of factors, including the Arab desire for greater autonomy within the Ottoman Empire, resentment towards Ottoman policies, and the influence of Arab nationalist movements. The Arab Revolt was a significant factor in the eventual defeat of the Ottoman Empire. The revolt helped to weaken Ottoman military power and tie up Ottoman forces that could have been deployed elsewhere. It also helped to increase support for Arab independence and nationalism, which would have a lasting impact on the region in the years to come. The Empire's defeat and the occupation of part of its territory by the Allied Powers in the aftermath of World War I, the Sykes–Picot Agreement had a significant impact on the Arab world and its people. The agreement divided the Arab territories of the Ottoman Empire into zones of control for France and Britain, ignoring the aspirations of the Arab people for independence and self-determination. Renaissance The Golden Age of Arab Civilization known as the "Islamic Golden Age", traditionally dated from the 8th century to the 13th century. The period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Siege of Baghdad in 1258. During this time, Arab scholars made significant contributions to fields such as mathematics, astronomy, medicine, and philosophy. These advancements had a profound impact on European scholars during the Renaissance. The Arabs shared its knowledge and ideas with Europe, including translations of Arabic texts. These translations had a significant impact on culture of Europe, leading to the transformation of many philosophical disciplines in the medieval Latin world. Additionally, the Arabs made original innovations in various fields, including the arts, agriculture, alchemy, music, and pottery, and traditional star names such as Aldebaran, scientific terms like alchemy (whence also chemistry), algebra, algorithm, etc. and names of commodities such as sugar, camphor, cotton, coffee, etc. From the medieval scholars of the Renaissance of the 12th century, who had focused on studying Greek and Arabic works of natural sciences, philosophy, and mathematics, rather than on such cultural texts. Arab logician, most notably Averroes, had inherited Greek ideas after they had invaded and conquered Egypt and the Levant. Their translations and commentaries on these ideas worked their way through the Arab West into Iberia and Sicily, which became important centers for this transmission of ideas. From the 11th to the 13th century, many schools dedicated to the translation of philosophical and scientific works from Classical Arabic to Medieval Latin were established in Iberia, most notably the Toledo School of Translators. This work of translation from Arab culture, though largely unplanned and disorganized, constituted one of the greatest transmissions of ideas in history. During the Timurid Renaissance spanning the late 14th, the 15th, and the early 16th centuries, there was a significant exchange of ideas, art, and knowledge between different cultures and civilizations. Arab scholars, artists, and intellectuals played a role in this cultural exchange, contributing to the overall intellectual atmosphere of the time. They participated in various fields, including literature, art, science, and philosophy. In the late 19th and early 20th centuries, the Arab Renaissance, also known as the Nahda, was a cultural and intellectual movement that emerged. The term "Nahda" means "awakening" or "renaissance" in Arabic, and refers to a period of renewed interest in Arabic language, literature, and culture. Modern period The modern period in Arab history refers to the time period from the late 19th century to the present day. During this time, the Arab world experienced significant political, economic, and social changes. One of the most significant events of the modern period was the collapse of the Ottoman Empire, the end of Ottoman rule led to the emergence of new nation-states in the Arab world. Sharif Hussein was supposed, in the event of the success of the Arab revolution and the victory of the Allies in World War I, to be able to establish an independent Arab state consisting of the Arabian Peninsula and the Fertile Crescent, including Iraq and the Levant. He aimed to become "King of the Arabs" in this state, however, the Arab revolution only succeeded in achieving some of its objectives, including the independence of the Hejaz and the recognition of Sharif Hussein as its king by the Allies.Arab nationalism emerged as a major movement in the early 20th century, with many Arab intellectuals, artists, and political leaders seeking to promote unity and independence for the Arab world. This movement gained momentum after World War II, leading to the formation of the Arab League and the creation of several new Arab states. Pan-Arabism that emerged in the early 20th century and aimed to unite all Arabs into a single nation or state. It emphasized on a shared ancestry, culture, history, language and identity and sought to create a sense of pan-Arab identity and solidarity. The roots of pan-Arabism can be traced back to the Arab Renaissance or Al-Nahda movement of the late 19th century, which saw a revival of Arab culture, literature, and intellectual thought. The movement emphasized the importance of Arab unity and the need to resist colonialism and foreign domination. One of the key figures in the development of pan-Arabism was the Egyptian statesman and intellectual, Gamal Abdel Nasser, who led the 1952 revolution in Egypt and became the country's president in 1954. Nasser promoted pan-Arabism as a means of strengthening Arab solidarity and resisting Western imperialism. He also supported the idea of Arab socialism, which sought to combine pan-Arabism with socialist principles. Similar attempts were made by other Arab leaders, such as Hafiz al-Assad, Ahmed Hassan al-Bakr, Faisal I of Iraq, Muammar Gaddafi, Saddam Hussein, Gaafar Nimeiry and Anwar Sadat. Many proposed unions aimed to create a unified Arab entity that would promote cooperation and integration among Arab countries. However, the initiatives faced numerous challenges and obstacles, including political divisions, regional conflicts, and economic disparities. The United Arab Republic (UAR) was a political union formed between Egypt and Syria in 1958, with the goal of creating a federal structure that would allow each member state to retain its identity and institutions. However, by 1961, Syria had withdrawn from the UAR due to political differences, and Egypt continued to call itself the UAR until 1971, when it became the Arab Republic of Egypt. In the same year the UAR was formed, another proposed political union, the Arab Federation, was established between Jordan and Iraq, but it collapsed after only six months due to tensions with the UAR and the 14 July Revolution. A confederation called the United Arab States, which included the UAR and the Mutawakkilite Kingdom of Yemen, was also created in 1958 but dissolved in 1961. Later attempts to create a political and economic union among Arab countries included the Federation of Arab Republics, which was formed by Egypt, Libya, and Syria in the 1970s but dissolved after five years due to political and economic challenges. Muammar Gaddafi, the leader of Libya, also proposed the Arab Islamic Republic with Tunisia, aiming to include Algeria and Morocco, instead the Arab Maghreb Union was formed in 1989. During the latter half of the 20th century, many Arab countries experienced political upheaval and conflicts, including, revolutions. The Arab-Israeli conflict remains a major issue in the region, and has resulted in ongoing tensions and periodic outbreaks of violence. In recent years, the Arab world has faced new challenges, including economic and social inequalities, demographic changes, and the impact of globalization. The Arab Spring was a series of pro-democracy uprisings and protests that swept across several countries in the Arab world in 2010 and 2011. The uprisings were sparked by a combination of political, economic, and social grievances and called for democratic reforms and an end to authoritarian rule. While the protests resulted in the downfall of some long-time authoritarian leaders, they also led to ongoing conflicts and political instability in other countries. Identity Arab identity is defined independently of religious identity, and pre-dates the spread of Islam, with historically attested Arab Christian kingdoms and Arab Jewish tribes. Today, however, most Arabs are Muslim, with a minority adhering to other faiths, largely Christianity, but also Druze and Baháʼí. Paternal descent has traditionally been considered the main source of affiliation in the Arab world when it comes to membership into an ethnic group or clan. Arab identity is shaped by a range of factors, including ancestry, history, language, customs, and traditions. Arab identity has been shaped by a rich history that includes the rise and fall of empires, colonization, and political turmoil. Despite the challenges faced by Arab communities, their shared cultural heritage has helped to maintain a sense of unity and pride in their identity. Today, Arab identity continues to evolve as Arab communities navigate complex political, social, and economic landscapes. Despite this, the Arab identity remains an important aspect of the cultural and historical fabric of the Arab world, and continues to be celebrated and preserved by communities around the world. Subgroups Arab tribes are prevalent in the Arabian Peninsula, Mesopotamia, Levant, Egypt, Maghreb, the Sudan region and Horn Africa. The Arabs of the Levant are traditionally divided into Qays and Yaman tribes. The distinction between Qays and Yaman dates back to the pre-Islamic era and was based on tribal affiliations and geographic locations.; they include Banu Kalb, Kinda, Ghassanids, and Lakhmids. The Qays were made up of tribes such as Banu Kilab, Banu Tayy, Banu Hanifa, and Banu Tamim, among others. The Yaman, on the other hand, were composed of tribes such as Banu Hashim, Banu Makhzum, Banu Umayya, and Banu Zuhra, among others. Most notable Arab tribes of Mesopotamia (Iraq) are Banu Khuza'ah, Shammar, Al-Dulaimi, Al-Jubouri, Al-Aniza, Al-Asadi, Al-Ali, Al-Duraji, Bani Hasan, Al-Khazraj, Banu Lam, Bani Malik, Al-Muntafiq, Al-Bu Nasir, Al-Dhafeer, Al-Musawi, Al-Ubaid, Otaibah, Al-Zubaidi, Mutair, Banu Tamim, Banu Kilab, Banu Asad and as well in Iran began well before the Arab conquest of Persia in 633 CE. The largest group of Iranian Arabs are the Ahwazi Arabs, including Banu Ka'b, Bani Turuf and the Musha'sha'iyyah sect. Smaller groups are the Khamseh nomads in Fars Province and the Arabs in Khorasan. As a result of the centuries-long Arab migration to the Maghreb, several Arab tribes (including Banu Hilal, Banu Sulaym and Maqil) settled in the Maghreb and formed the sub-tribes which exist to present-day. The most notable Arab tribes of Morocco include Abda, Ahl Rachida, Azwafit, Banu Ma'qil, Banu Tamim, Beni Ahsen, Beni Amir, Beni Guil, Beni Ḥassān, Banu Hilal, Beni Khirane, Beni Mathar, Beni Moussa, Banu Sulaym, Beni Zemmour, Chaouia, Doukkala, Hyayna, Khlout, Mzab, Oulad Delim, Oulad Tidrarin, Oulad Zyan, Rahamna, Sless, Zaër, Zughba, Zyayda. The Banu Hilal spent almost a century in Egypt before moving to Libya, Tunisia and Algeria, and another century later moved to Morocco. The most well known Arab tribes of Algeria are Chaamba, Dhouaouda, Doui-Menia, Ghenanma, Beni Hassan, Ouled Djerir, Awlad Sidi Shaykh, Banu Tamim, Thaaliba, Ouled Nail, Beni Amer, Hamyan, Riyah, Zughba, Athbaj, Ahl Ben Ali, Banu Suwayd, Awlad Sidi Yahya, Mirdas and Banu Latif. Most notable Arab tribes of Sudan are Ababda, Artega, Awadia, Awlad Himayd, Batahin, Bedaria, Beni Halba, Dubasiyin, Fadnia, Fezara, Gawamaa, Gimma, Habbaniya, Hasania, Hawazma, Humr, Husseinat, Ja'alin, Kababish, Kawahla, Maalia, Mahamid, Manasir, Messiria, Rashaida, Rizeigat, Rubatab, Rufa'a, Selim, Shaigiya, Shukria, Ta’isha. According to Arab traditions, tribes are divided into different divisions called Arab skulls, which are described in the traditional custom of strength, abundance, victory, and honor. A number of them branched out, which later became independent tribes (sub-tribes). The majority of Arab tribes are descended from these major tribes. They are: Bakr, has descendants in Arabia and Iraq. Kinanah, has descendants in Arabia, Iraq, Egypt, Sudan, Palestine, Tunisia, Morocco, and Syria. Hawazin, has descendants in Arabia, Libya, Algeria, Morocco, Sudan, and Iraq. Tamim, has descendants in Arabia, Iraq, Iran, Palestine, Algeria, and Morocco Azd, has descendants in Arabia, Iraq, Levant, and North Africa. Ghatafan, has descendants in Arabia and the Maghreb. Madhhij, has descendants in Arabia and Iraq. Abd al-Qays, has descendants in Arabia. Al Qays (القيس), has descendants in Arabia. Quda'a, has descendants in Arabia, Syria, and North Africa. Geographic distribution Arab homeland The total number of Arabs living in the Arab nations is estimated at 366 million by the CIA Factbook (as of 2014). The estimated number of Arabs in countries outside the Arab League is estimated at 17.5 million, yielding a total of close to 384 million. The Arab world stretches around , from the Atlantic Ocean in the west to the Arabian Sea in the east and from the Mediterranean Sea in the north to the Horn of Africa and the Indian Ocean in the southeast. Arab diaspora Arab diaspora refers to descendants of the Arab immigrants who, voluntarily or as refugees, emigrated from their native lands in non-Arab countries, primarily in East Africa, South America, Europe, North America, Australia and parts of South Asia, Southeast Asia, the Caribbean, and West Africa. According to the International Organization for Migration, there are 13 million first-generation Arab migrants in the world, of which 5.8 million reside in Arab countries. Arab expatriates contribute to the circulation of financial and human capital in the region and thus significantly promote regional development. In 2009, Arab countries received a total of US$35.1 billion in remittance in-flows and remittances sent to Jordan, Egypt and Lebanon from other Arab countries are 40 to 190 per cent higher than trade revenues between these and other Arab countries. The 250,000 strong Lebanese community in West Africa is the largest non-African group in the region. Arab traders have long operated in Southeast Asia and along the East Africa's Swahili coast. Zanzibar was once ruled by Omani Arabs. Most of the prominent Indonesians, Malaysians, and Singaporeans of Arab descent are Hadhrami people with origins in southern Arabia in the Hadramawt coastal region. Europe There are millions of Arabs living in Europe, mostly concentrated in France (about 6,000,000 in 2005). Most Arabs in France are from the Maghreb but some also come from the Mashreq areas of the Arab world. Arabs in France form the second largest ethnic group after French people. In Italy, Arabs first arrived on the southern island of Sicily in the 9th century. The largest modern societies on the island from the Arab world are Tunisians and Moroccans, who make up 10.9% and 8% respectively of the foreign population of Sicily, which in itself constitutes 3.9% of the island's total population. The modern Arab population of Spain numbers 1,800,000, and there have been Arabs in Spain since the early 8th century when the Muslim conquest of Hispania created the state of Al-Andalus. Arabs In Germany the Arab population numbers over 1,401,950. in the United Kingdom between 366,769 and 500,000, and in Greece between 250,000 and 750,000). In addition, Greece is home to people from Arab countries who have the status of refugees (e.g. refugees of the Syrian civil war). In the Netherlands 180,000, and in Denmark 121,000. Other countries are also home to Arab populations, including Norway, Austria, Bulgaria, Switzerland, North Macedonia, Romania and Serbia. As of late 2015, Turkey had a total population of 78.7 million, with Syrian refugees accounting for 3.1% of that figure based on conservative estimates. Demographics indicated that the country previously had 1,500,000 to 2,000,000 Arab residents, Turkey's Arab population is now 4.5 to 5.1% of the total population, or approximately 4–5 million people. Americas Arab immigration to the United States began in larger numbers during the 1880s, and today, an estimated 3.7 million Americans have some Arabic background. Arab Americans are found in every state, but more than two thirds of them live in just ten states, and one-third live in Los Angeles, Detroit, and New York City specifically. Most Arab Americans were born in the US, and nearly 82% of US-based Arabs are citizens. Arabs immigrants began to arrive in Canada in small numbers in 1882. Their immigration was relatively limited until 1945, after which time it increased progressively, particularly in the 1960s and thereafter. According to the website "Who are Arab Canadians," Montreal, the Canadian city with the largest Arab population, has approximately 267,000 Arab inhabitants. Latin America has the largest Arab population outside of the Arab World. Latin America is home to anywhere from 17–25 to 30 million people of Arab descent, which is more than any other diaspora region in the world. The Brazilian and Lebanese governments claim there are 7 million Brazilians of Lebanese descent. Also, the Brazilian government claims there are 4 million Brazilians of Syrian descent. Other large Arab communities includes Argentina (about 3,500,000) The interethnic marriage in the Arab community, regardless of religious affiliation, is very high; most community members have only one parent who has Arab ethnicity. Colombia (over 3,200,000), Venezuela (over 1,600,000), Mexico (over 1,100,000), Chile (over 800,000), and Central America, particularly El Salvador, and Honduras (between 150,000 and 200,000). Arab Haitians (257,000) a large number of whom live in the capital are more often than not, concentrated in financial areas where the majority of them establish businesses. Caucasus In 1728, a Russian officer described a group of Arab nomads who populated the Caspian shores of Mughan (in present-day Azerbaijan) and spoke a mixed Turkic-Arabic language. It is believed that these groups migrated to the South Caucasus in the 16th century. The 1888 edition of Encyclopædia Britannica also mentioned a certain number of Arabs populating the Baku Governorate of the Russian Empire. They retained an Arabic dialect at least into the mid-19th century, there are nearly 30 settlements still holding the name Arab (for example, Arabgadim, Arabojaghy, Arab-Yengija, etc.). From the time of the Arab conquest of the South Caucasus, continuous small-scale Arab migration from various parts of the Arab world occurred in Dagestan. The majority of these lived in the village of Darvag, to the north-west of Derbent. The latest of these accounts dates to the 1930s. Most Arab communities in southern Dagestan underwent linguistic Turkicisation, thus nowadays Darvag is a majority-Azeri village. Central, South, East and Southeast Asia According to the History of Ibn Khaldun, the Arabs that were once in Central Asia have been either killed or have fled the Tatar invasion of the region, leaving only the locals. However, today many people in Central Asia identify as Arabs. Most Arabs of Central Asia are fully integrated into local populations, and sometimes call themselves the same as locals (for example, Tajiks, Uzbeks) but they use special titles to show their Arab origin such as Sayyid, Khoja or Siddiqui. There are only two communities in India which claim Arab descent, the Chaush of the Deccan region and the Chavuse of Gujarat. These groups are largely descended from Hadhrami migrants who settled in these two regions in the 18th century. However, neither community still speaks Arabic, although the Chaush have seen re-immigration to Eastern Arabia and thus a re-adoption of Arabic. In South Asia, where Arab ancestry is considered prestigious, some communities have origin myths that claim Arab ancestry. Several communities following the Shafi'i madhab (in contrast to other South Asian Muslims who follow the Hanafi madhab) claim descent from Arab traders like the Konkani Muslims of the Konkan region, the Mappilla of Kerala, and the Labbai and Marakkar of Tamil Nadu and a few Christian groups in India that claim and have Arab roots are situated in the state of Kerala. South Asian Iraqi biradri may have records of their ancestors who migrated from Iraq in historical documents. The Sri Lankan Moors are the third largest ethnic group in Sri Lanka, constituting 9.23% of the country's total population. Some sources trace the ancestry of the Sri Lankan Moors to Arab traders who settled in Sri Lanka at some time between the 8th and 15th centuries. There are about 5,000,000 Native Indonesians with Arab ancestry, of Hadrami descent. Sub-Saharan Africa Afro-Arabs are individuals and groups from Africa who are of partial Arab descent. Most Afro-Arabs inhabit the Swahili Coast in the African Great Lakes region, although some can also be found in parts of the Arab world. Large numbers of Arabs migrated to West Africa, particularly Côte d'Ivoire (home to over 100,000 Lebanese), Senegal (roughly 30,000 Lebanese), Sierra Leone (roughly 10,000 Lebanese today; about 30,000 prior to the outbreak of civil war in 1991), Liberia, and Nigeria. Since the end of the civil war in 2002, Lebanese traders have become re-established in Sierra Leone. The Arabs of Chad occupy northern Cameroon and Nigeria (where they are sometimes known as Shuwa), and extend as a belt across Chad and into Sudan, where they are called the Baggara grouping of Arab ethnic groups inhabiting the portion of Africa's Sahel. There are 171,000 in Cameroon, 150,000 in Niger), and 107,000 in the Central African Republic. Religion Arabs are mostly Muslims with a Sunni majority and a Shia minority, one exception being the Ibadis, who predominate in Oman. Arab Christians generally follow Eastern Churches such as the Greek Orthodox and Greek Catholic churches, though a minority of Protestant Church followers also exists. There are also Arab communities consisting of Druze and Baháʼís. Historically, there were also sizeable populations of Arab Jews around the Arab World. Before the coming of Islam, most Arabs followed a pagan religion with a number of deities, including Hubal, Wadd, Allāt, Manat, and Uzza. A few individuals, the hanifs, had apparently rejected polytheism in favor of monotheism unaffiliated with any particular religion. Some tribes had converted to Christianity or Judaism. The most prominent Arab Christian kingdoms were the Ghassanid and Lakhmid kingdoms. When the Himyarite king converted to Judaism in the late 4th century, the elites of the other prominent Arab kingdom, the Kindites, being Himyirite vassals, apparently also converted (at least partly). With the expansion of Islam, polytheistic Arabs were rapidly Islamized, and polytheistic traditions gradually disappeared. Today, Sunni Islam dominates in most areas, vastly so in Levant, North Africa, West Africa and the Horn of Africa. Shia Islam is dominant in Bahrain and southern Iraq while northern Iraq is mostly Sunni. Substantial Shia populations exist in Lebanon, Yemen, Kuwait, Saudi Arabia, northern Syria and Al-Batinah Region in Oman. There are small numbers of Ibadi and non-denominational Muslims too. The Druze community is concentrated in Levant. Christianity had a prominent presence In pre-Islamic Arabia among several Arab communities, including the Bahrani people of Eastern Arabia, the Christian community of Najran, in parts of Yemen, and among certain northern Arabian tribes such as the Ghassanids, Lakhmids, Taghlib, Banu Amela, Banu Judham, Tanukhids and Tayy. In the early Christian centuries, Arabia was sometimes known as Arabia heretica, due to its being "well known as a breeding-ground for heterodox interpretations of Christianity." Christians make up 5.5% of the population of Western Asia and North Africa. In Lebanon, Christians number about 40.5% of the population. In Syria, Christians make up 10% of the population. Christians in Palestine make up 8% and 0.7% of the populations, respectively. In Egypt, Christians number about 10% of the population. In Iraq, Christians constitute 0.1% of the population. In Israel, Arab Christians constitute 2.1% (roughly 9% of the Arab population). Arab Christians make up 8% of the population of Jordan. Most North and South American Arabs are Christian, so are about half of the Arabs in Australia who come particularly from Lebanon, Syria and Palestine. One well known member of this religious and ethnic community is Saint Abo, martyr and the patron saint of Tbilisi, Georgia. Arab Christians also live in holy Christian cities such as Nazareth, Bethlehem and the Christian Quarter of the Old City of Jerusalem and many other villages with holy Christian sites. Culture Arab culture is shaped by a long and rich history that spans thousands of years, from the Atlantic Ocean in the west to the Arabian Sea in the east, and from the Mediterranean Sea in the north to the Horn of Africa and the Indian Ocean in the southeast. The various religions the Arabs have adopted throughout their history and the various empires and kingdoms that have ruled and took lead of the Arabic civilization have contributed to the ethnogenesis and formation of modern Arab culture. Language, literature, gastronomy, art, architecture, music, spirituality, philosophy and mysticism are all part of the cultural heritage of the Arabs. One of the defining features of Arab culture is its strong emphasis on family and community. Social bonds and obligations are highly valued, and individuals are expected to prioritize the needs and well-being of their families and communities over their own personal interests. Hospitality is also a key aspect of Arab culture, with guests traditionally treated with great warmth and generosity. Arabs share basic beliefs and values that cross national and social class boundaries. Social attitudes have remained constant because Arab society is more conservative and demands conformity from its members. Language Arabic is a Semitic language of the Afro-Asiatic Family. The first evidence for the emergence of the language appears in military accounts from 853 BCE. Today it has developed widely used as a lingua franca for more than 500 million people. It is also a liturgical language for 1.7 billion Muslims. Arabic is one of six official languages of the United Nations, and is revered in Islam as the language of the Quran. Arabic has two main registers. Classical Arabic is the form of the Arabic language used in literary texts from Umayyad and Abbasid times (7th to 9th centuries). It is based on the medieval dialects of Arab tribes. Modern Standard Arabic (MSA) is the direct descendant used today throughout the Arab world in writing and in formal speaking, for example, prepared speeches, some radio broadcasts, and non-entertainment content, while the lexis and stylistics of Modern Standard Arabic are different from Classical Arabic. There are also various regional dialects of colloquial spoken Arabic that both vary greatly from both each other and from the formal written and spoken forms of Arabic. Mythology Arabic mythology comprises the ancient beliefs of the Arabs. Prior to Islam the Kaaba of Mecca was covered in symbols representing the myriad demons, djinn, demigods, or simply tribal gods and other assorted deities which represented the polytheistic culture of pre-Islamic. It has been inferred from this plurality an exceptionally broad context in which mythology could flourish. The most popular beasts and demons of Arabian mythology are Bahamut, Dandan, Falak, Ghoul, Hinn, Jinn, Karkadann, Marid, Nasnas, Qareen, Roc, Shadhavar, Werehyena and other assorted creatures which represented the profoundly polytheistic environment of pre-Islamic. The most prominent symbol of Arabian mythology is the Jinn or genie. Jinns are supernatural beings that can be good or evil. They are not purely spiritual, but are also physical in nature, being able to interact in a tactile manner with people and objects and likewise be acted upon. The jinn, humans, and angels make up the known sapient creations of God. Ghouls also feature in the mythology as a monster or evil spirit associated with graveyards and consuming human flesh. In Arabic folklore, ghouls belonged to a diabolic class of jinn and were said to be the offspring of Iblīs, the prince of darkness in Islam. They were capable of constantly changing form, but always retained donkey's hooves. Literature The Quran, the main holy book of Islam, had a significant influence on the Arabic language, and marked the beginning of Arabic literature. Muslims believe it was transcribed in the Arabic dialect of the Quraysh, the tribe of Muhammad. As Islam spread, the Quran had the effect of unifying and standardizing Arabic. Not only is the Quran the first work of any significant length written in the language, but it also has a far more complicated structure than the earlier literary works with its 114 suwar (chapters) which contain 6,236 ayat (verses). It contains injunctions, narratives, homilies, parables, direct addresses from God, instructions and even comments on how the Quran will be received and understood. It is also admired for its layers of metaphor as well as its clarity, a feature which is mentioned in An-Nahl, the 16th surah. Al-Jahiz (born 776, in Basra – December 868/January 869) was an Arab prose writer and author of works of literature, Mu'tazili theology, and politico-religious polemics. A leading scholar in the Abbasid Caliphate, his canon includes two hundred books on various subjects, including Arabic grammar, zoology, poetry, lexicography, and rhetoric. Of his writings, only thirty books survive. Al-Jāḥiẓ was also one of the first Arabian writers to suggest a complete overhaul of the language's grammatical system, though this would not be undertaken until his fellow linguist Ibn Maḍāʾ took up the matter two hundred years later. There is a small remnant of pre-Islamic poetry, but Arabic literature predominantly emerges in the Middle Ages, during the Golden Age of Islam. Imru' al-Qais was a king and poet in the 6th century, he was the last king of Kindite. He is among the finest Arabic poetry to date, as well sometimes considered the father of Arabic poetry. Kitab al-Aghani by Abul-Faraj was called by the 14th-century historian Ibn Khaldun the register of the Arabs. Literary Arabic is derived from Classical Arabic, based on the language of the Quran as it was analyzed by Arabic grammarians beginning in the 8th century. A large portion of Arabic literature before the 20th century is in the form of poetry, and even prose from this period is either filled with snippets of poetry or is in the form of saj or rhymed prose. The ghazal or love poem had a long history being at times tender and chaste and at other times rather explicit. In the Sufi tradition the love poem would take on a wider, mystical and religious importance. Arabic epic literature was much less common than poetry, and presumably originates in oral tradition, written down from the 14th century or so. Maqama or rhymed prose is intermediate between poetry and prose, and also between fiction and non-fiction. Maqama was an incredibly popular form of Arabic literature, being one of the few forms which continued to be written during the decline of Arabic in the 17th and 18th centuries. Arabic literature and culture declined significantly after the 13th century, to the benefit of Turkish and Persian. A modern revival took place beginning in the 19th century, alongside resistance against Ottoman rule. The literary revival is known as al-Nahda in Arabic, and was centered in Egypt and Lebanon. Two distinct trends can be found in the nahda period of revival. The first was a neo-classical movement which sought to rediscover the literary traditions of the past, and was influenced by traditional literary genres—such as the maqama—and works like One Thousand and One Nights. In contrast, a modernist movement began by translating Western modernist works—primarily novels—into Arabic. A tradition of modern Arabic poetry was established by writers such as Francis Marrash, Ahmad Shawqi and Hafiz Ibrahim. Iraqi poet Badr Shakir al-Sayyab is considered to be the originator of free verse in Arabic poetry. Cuisine Arab cuisine is largely divided into Khaleeji cuisine, Levantine cuisine and Maghrebi cuisine. Is characterized by a variety of herbs and spices, including cumin, coriander, cinnamon, sumac, za'atar, and cardamom, which add depth and complexity to dishes. In the Maghreb, is known for its use of Couscous, a type of semolina pasta that is served with stews or tagines made with meat, vegetables, and aromatic spices such as cumin, coriander, and saffron. In the Levant, its cuisine is known for its mezze, a variety of small dishes that are served as appetizers or side dishes. Mezze dishes include Hummus, Baba ghanoush, Tabouleh and stuffed grape leaves, is also known for its Kebabs, Shawarma and Falafel. Gulf cuisine leans heavily on meat and rice and is heavily spiced, its use of rice, meat, and spices, such as saffron and cardamom. Mansaf, a traditional dish from Jordan made with lamb, rice, and a fermented yogurt sauce, is a popular dish in the Arabian Peninsula. Fertile Crescent cuisine is known for its use of herbs and spices, such as mint, dill, and cilantro. Tharid, a soup made with bread, lamb, and vegetables, is a traditional Iraqi dish, as well other popular Iraqi dishes include Dolma, a dish of stuffed vegetables, and kubba, a dish of stuffed meatballs. Arab cuisine is also known for its sweets and desserts, such as Knafeh, Baklava, Halva, and Qatayef. Arabic coffee, or qahwa, is a traditional drink that is served with dates. Arab cuisine has influenced other cuisines various cultures, including Ottoman, Persian, and Andalusian. Arab cuisine is rich in history and culture, and each region has its unique flavors and cooking styles that reflect its traditions and heritage. One will find the following items in most dishes; cinnamon, fish (in coastal areas), garlic, lamb (or veal), mild to hot sauces, mint, onion, rice, saffron, sesame, yogurt, spices due to heavy trading between the two regions. Tea, thyme (or oregano), turmeric, a variety of fruits (primarily citrus) and vegetables such as cucumbers, eggplants, lettuce, tomato, green pepper, green beans, zucchini and parsley. Art Arabic art has taken various forms, including, among other things, jewelry, textiles and architecture. Arabic script has also traditionally been heavily embellished with often colorful Arabic calligraphy, with one notable and widely used example being Kufic script. Arabic miniatures (Arabic: الْمُنَمْنَمَات الْعَرَبِيَّة, Al-Munamnamāt al-ʿArabīyah) are small paintings on paper, usually book or manuscript illustrations but also sometimes separate artworks that occupy entire pages. The earliest example dates from around 690 CE, with a flourishing of the art from between 1000 and 1200 CE in the Abbasid caliphate. The art form went through several stages of evolution while witnessing the fall and rise of several Arab caliphates. Arab miniaturists got totally assimilated and subsequently disappeared due to the Ottoman occupation of the Arab world. Nearly all forms of Islamic miniatures (Persian miniatures, Ottoman miniatures and Mughal miniatures) owe their existences to Arabic miniatures, as Arab patrons were the first to demand the production of illuminated manuscripts in the Caliphate, it was not until the 14th century that the artistic skill reached the non-Arab regions of the Caliphate. Despite the considerable changes in Arabic miniature style and technique, even during their last decades, the early Umayyad Arab influence could still be noticed. Arabic miniature artists include Ismail al-Jazari, who illustrated his own Book of Knowledge of Ingenious Mechanical Devices, and the Abbasid artist, Yahya Al-Wasiti, who probably lived in Baghdad in the late Abbasid era (12th to 13th-centuries), was one of the pre-eminent exponents of the Baghdad school. In 1236-1237, he is known to have transcribed and illustrated the book, Maqamat (also known as the Assemblies or the Sessions), a series of anecdotes of social satire written by Al-Hariri of Basra. The narrative concerns the travels of a middle-aged man as he uses his charm and eloquence to swindle his way across the Arabic world. With most surviving Arabic manuscripts in western museums, Arabic miniatures occupy very little space in modern Arab culture. Arabesque is a form of artistic decoration consisting of "surface decorations based on rhythmic linear patterns of scrolling and interlacing foliage, tendrils" or plain lines, often combined with other elements. Another definition is "Foliate ornament, typically using leaves, derived from stylised half-palmettes, which were combined with spiralling stems". It usually consists of a single design which can be 'tiled' or seamlessly repeated as many times as desired. Architecture Arabic Architecture has a deep diverse history as well Arab world is home to the greatest number of UNESCO World Heritage Sites (List of World Heritage Sites in the Arab states), it dates to the dawn of the history in pre-Islamic Arabia and includes various styles from the Nabataean architecture developed in the ancient kingdom of the Nabataeans, who were a nomadic Arab tribe that controlled a significant portion of the Middle East from the 4th century BCE to the 2nd century CE. The Nabataeans were known for their skill in carving out elaborate buildings, tombs, and other structures from the sandstone cliffs of the region. One of the most famous examples of Nabataean architecture is the city of Petra, which is located in modern-day Jordan, was the capital of the Nabataean kingdom and is renowned for its impressive rock-cut architecture. Prior to the start of the Arab conquests, Arab tribal client states, the Lakhmids and Ghassanids, played a significant role in transmitting and adapting the architectural traditions of the Byzantine and Sasanian empires to the later Arab Islamic dynasties, which lasted from the 7th to the 13th century, was characterized by a fusion of various architectural styles and techniques. The Arab empire expanded rapidly, and with it, came a diverse range of architectural influences. One of the most notable architectural achievements of the Arab Empire is the Great Mosque of Damascus in Syria, which was built in the early 8th century, was constructed on the site of a Christian basilica and incorporated elements of Byzantine and Roman architecture, such as arches, columns, and intricate mosaics. Another important architectural is the Al-Aqsa Mosque in Jerusalem, which was built in the late 7th century. The mosque features an impressive dome and a large prayer hall, as well as intricate geometric patterns and calligraphy on the walls. During the Umayyad and Abbasid periods of the Arab Empire, many new architectural forms were developed, including the horseshoe arch, the pointed arch, and the muqarnas, a type of vaulting used to create intricate, three-dimensional geometric patterns. These Arab client states were located on the borders of the two empires, and as such, they were exposed to the cultural and architectural influences of both. In Sicily, Arab-Norman architecture combined Occidental features, such as the Classical pillars and friezes, with typical Arabic decorations and calligraphy. The principal Islamic architectural types are: the Mosque, the Tomb, the Palace and the Fort. From these four types, the vocabulary of Islamic architecture is derived and used for other buildings such as public baths, fountains and domestic architecture. Music Arabic music, while independent and flourishing in the 2010s, has a long history of interaction with many other regional musical styles and genres. It is an amalgam of the music of the Arab people in the Arabian Peninsula and the music of all the peoples that make up the Arab world today. Pre-Islamic Arab music was similar to that of Ancient Middle Eastern music. Most historians agree that there existed distinct forms of music in the Arabian peninsula in the pre-Islamic period between the 5th and 7th century CE. Arab poets of that "Jahili poets", meaning "the poets of the period of ignorance"—used to recite poems with a high notes. It was believed that Jinns revealed poems to poets and music to musicians. By the 11th century, Islamic Iberia had become a center for the manufacture of instruments. These goods spread gradually throughout France, influencing French troubadours, and eventually reaching the rest of Europe. The English words lute, rebec, and naker are derived from Arabic oud, rabab, and naqareh. A number of musical instruments used in classical music are believed to have been derived from Arabic musical instruments: the lute was derived from the Oud, the rebec (ancestor of violin) from the Maghreb rebab, the guitar from qitara, which in turn was derived from the Persian Tar, naker from naqareh, adufe from al-duff, alboka from al-buq, anafil from al-nafir, exabeba from al-shabbaba (flute), atabal (bass drum) from al-tabl, atambal from al-tinbal, the balaban, the castanet from kasatan, sonajas de azófar from sunuj al-sufr, the conical bore wind instruments, the xelami from the sulami or fistula (flute or musical pipe), the shawm and dulzaina from the reed instruments zamr and al-zurna, the gaita from the ghaita, rackett from iraqya or iraqiyya, geige (violin) from ghichak, and the theorbo from the tarab. During the 1950s and the 1960s, Arabic music began to take on a more Western tone – artists Umm Kulthum, Abdel Halim Hafez, and Shadia along with composers Mohamed Abd al-Wahab and Baligh Hamdi pioneered the use of western instruments in Egyptian music. By the 1970s several other singers had followed suit and a strand of Arabic pop was born. Arabic pop usually consists of Western styled songs with Arabic instruments and lyrics. Melodies are often a mix between Eastern and Western. Beginning in the mid-1980s, Lydia Canaan, musical pioneer widely regarded as the first rock star of the Middle East Spirituality Arab polytheism was the dominant religion in pre-Islamic Arabia. Gods and goddesses, including Hubal and the goddesses al-Lāt, Al-'Uzzá and Manāt, were worshipped at local shrines, such as the Kaaba in Mecca, whilst Arabs in the south, in what is today's Yemen, worshipped various gods, some of which represented the Sun or Moon. Different theories have been proposed regarding the role of Allah in Meccan religion. Many of the physical descriptions of the pre-Islamic gods are traced to idols, especially near the Kaaba, which is said to have contained up to 360 of them. Until about the fourth century, almost all Arabs practised polytheistic religions. Although significant Jewish and Christian minorities developed, polytheism remained the dominant belief system in pre-Islamic Arabia. The religious beliefs and practices of the nomadic bedouin were distinct from those of the settled tribes of towns such as Mecca. Nomadic religious belief systems and practices are believed to have included fetishism, totemism and veneration of the dead but were connected principally with immediate concerns and problems and did not consider larger philosophical questions such as the afterlife. Settled urban Arabs, on the other hand, are thought to have believed in a more complex pantheon of deities. While the Meccans and the other settled inhabitants of the Hejaz worshipped their gods at permanent shrines in towns and oases, the bedouin practised their religion on the move. Most notable Arab gods and goddesses: 'Amm, A'ra, Abgal, Allah, Al-Lat, Al-Qaum, Almaqah, Anbay, ʿAṯtar, Basamum, Dhu l-Khalasa, Dushara, Haukim, Hubal, Isāf and Nā'ila, Manaf, Manāt, Nasr, Nuha, Quzah, Ruda, Sa'd, Shams, Samas, Syn, Suwa', Ta'lab, Theandrios, al-‘Uzzá, Wadd, Ya'uq, Yaghūth, Yatha, Aglibol, Astarte, Atargatis, Baalshamin, Bēl, Bes, Ēl, Ilāh, Inanna/Ishtar, Malakbel, Nabū, Nebo, Nergal, Yarhibol. Philosophy The philosophical thought in the Arab world is heavily influenced by Arabic Philosophy. Schools of Arabic/Islamic thought include Avicennism and Averroism. The first great Arab thinker in the Islamic tradition is widely regarded to be al-Kindi (801–873 A.D.), a Neo-Platonic philosopher, mathematician and scientist who lived in Kufa and Baghdad (modern day Iraq). After being appointed by the Abbasid Caliphs to translate Greek scientific and philosophical texts into Arabic, he wrote a number of original treatises of his own on a range of subjects, from metaphysics and ethics to mathematics and pharmacology. Much of his philosophical output focuses on theological subjects such as the nature of God, the soul and prophetic knowledge. Doctrines of the Arabic philosophers of the 9th–12th century who influenced medieval Scholasticism in Europe. The Arabic tradition combines Aristotelianism and Neoplatonism with other ideas introduced through Islam. Influential thinkers include the non-Arabs al-Farabi and Avicenna. The Arabic philosophic literature was translated into Hebrew and Latin, this contributed to the development of modern European philosophy. The Arabic tradition was developed by Moses Maimonides and Ibn Khaldun. Science Arabic science underwent considerable development during the Middle Ages (8th to 13th centuries CE), a source of knowledge that later spread throughout Medieval Europe and greatly influenced both medical practice and education. The language of recorded science was Arabic. Scientific treatises were composed by thinkers originating from across the Muslim world. These accomplishments occurred after Muhammad united the Arab tribes and the spread of Islam beyond the Arabian peninsula. Within a century after Muhammed's death (632 CE), an empire ruled by Arabs was established. It encompassed a large part of the planet, stretching from southern Europe to North Africa to Central Asia and on to India. In 711 CE, Arab Muslims invaded southern Spain; al-Andalus was a center of Arabic scientific accomplishment. Soon after, Sicily too joined the greater Islamic world. Another center emerged in Baghdad from the Abbasids, who ruled part of the Islamic world during a historic period later characterized as the "Golden Age" (~750 to 1258 CE). This era can be identified as the years between 692 and 945, and ended when the caliphate was marginalized by local Muslim rulers in Baghdad – its traditional seat of power. From 945 onward until the sacking of Baghdad by the Mongols in 1258, the Caliph continued on as a figurehead, with power devolving more to local subordinates. The pious scholars of Islam, men and women collectively known as the ulama, were the most influential element of society in the fields of Sharia law, speculative thought and theology. Arabic scientific achievement is not as yet fully understood, but is very large. These achievements encompass a wide range of subject areas, especially mathematics, astronomy, and medicine. Other subjects of scientific inquiry included physics, alchemy and chemistry, cosmology, ophthalmology, geography and cartography, sociology, and psychology. Al-Battani was an astronomer, astrologer and mathematician of the Islamic Golden Age. His work is considered instrumental in the development of science and astronomy. One of Al-Battani's best-known achievements in astronomy was the determination of the solar year as being 365 days, 5 hours, 46 minutes and 24 seconds which is only 2 minutes and 22 seconds off. In mathematics, al-Battānī produced a number of trigonometrical relationships. Al-Zahrawi, regarded by many as the greatest surgeon of the middle ages. His surgical treatise "De chirurgia" is the first illustrated surgical guide ever written. It remained the primary source for surgical procedures and instruments in Europe for the next 500 years. The book helped lay the foundation to establish surgery as a scientific discipline independent from medicine, earning al-Zahrawi his name as one of the founders of this field. Other notable Arabic contributions include among other things: the pioneering of organic chemistry by Jābir ibn Hayyān, establishing the science of cryptology and cryptanalysis by al-Kindi, the development of analytic geometry by Ibn al-Haytham, who has been described as the "world's first true scientist", the discovery of the pulmonary circulation by Ibn al-Nafis, the discovery of the itch mite parasite by Ibn Zuhr, the first use of irrational numbers as an algebraic objects by Abū Kāmil, the first use of the positional decimal fractions by al-Uqlidisi, the development of the Arabic numerals and an early algebraic symbolism in the Maghreb, the Thabit number and Thābit theorem by Thābit ibn Qurra, the discovery of several new trigonometric identities by Ibn Yunus and al-Battani, the mathematical proof for Ceva's theorem by Ibn Hűd, the first accurate lunar model by Ibn al-Shatir, the invention of the torquetum by Jabir ibn Aflah, the invention of the universal astrolabe and the equatorium by al-Zarqali, the first description of the crankshaft by al-Jazari, the anticipation of the inertia concept by Averroes, the discovery of the physical reaction by Avempace, the identification of more than 200 new plants by Ibn al-Baitar the Arab Agricultural Revolution, and the Tabula Rogeriana, which was the most accurate world map in pre-modern times by al-Idrisi. The birth of the University institution can be traced to this development, as several universities and educational institutions of the Arab world such as the University of Al Quaraouiyine, Al Azhar University, and Al Zaytuna University are considered to be the oldest in the world. Founded by Fatima al Fihri in 859 as a mosque, the University of Al Quaraouiyine in Fez is the oldest existing, continually operating and the first degree awarding educational institution in the world according to UNESCO and Guinness World Records and is sometimes referred to as the oldest university. There are many scientific Arabic loanwords in Western European languages, including English, mostly via Old French. This includes traditional star names such as Aldebaran, scientific terms like alchemy (whence also chemistry), algebra, algorithm, alcohol, alkali, cipher, zenith, etc. Under Ottoman rule, cultural life and science in the Arab world declined. In the 20th and 21st centuries, Arabs who have won important science prizes include Ahmed Zewail and Elias Corey (Nobel Prize), Michael DeBakey and Alim Benabid (Lasker Award), Omar M. Yaghi (Wolf Prize), Huda Zoghbi (Shaw Prize), Zaha Hadid (Pritzker Prize), and Michael Atiyah (both Fields Medal and Abel Prize). Rachid Yazami was one of the co-inventors of the lithium-ion battery, and Tony Fadell was important in the development of the iPod and the iPhone. Theatre Arab theatre is a rich and diverse cultural form that encompasses a wide range of styles, genres, and historical influences. Its roots in the pre-Islamic era, when poetry, storytelling, and musical performances were the main forms of artistic expressionIt refers to theatrical performances that are created by Arab playwrights, actors, and directors. The roots of Arab theatre can be traced back to ancient Arabic poetry and storytelling, which often incorporated music and dance. In the early Arabic period, storytelling evolved into a more formalized art form that was performed in public gatherings and festivals. During the Islamic Golden Age in the 8th and 9th centuries, the city of Baghdad emerged as a hub of intellectual and artistic activity, including theatre. The court of the Abbasid Caliphate was home to many influential playwrights and performers, who helped to develop and popularize theatre throughout the Islamic world. Arab theatre has a long tradition of incorporating comedy and satire into its performances, often using humor to address social and political issues. Arab theatre encompasses a wide range of dramatic genres, including tragedy, melodrama, and historical plays. Many Arab playwrights have used drama to address contemporary issues, the role of women in Arab society, and the challenges facing young people in the modern world. In recent decades, many Arab theatre artists have pushed the boundaries of the form, experimenting with new styles and techniques. This has led to the emergence of a vibrant contemporary theatre scene in many Arab countries, with innovative productions and performances that challenge traditional notions of Arab identity and culture. Fashion Arab fashion and design have a rich history and cultural significance that spans centuries, each with its unique fashion and design traditions. One of the most notable aspects of Arab fashion is the use of luxurious fabrics and intricate embroidery. Traditional garments, such as the Abaya and Thobe, are often made from high-quality fabrics like silk, satin, brocade, and are embellished with intricate embroidery and beading. In recent years, Arab fashion has gained global recognition, with designers like Elie Saab, Zuhair Murad, and Reem Acra showcasing their designs on international runways. These designers incorporate traditional Arab design elements into their collections, such as ornate patterns, luxurious fabrics, and intricate embellishments. In addition to fashion, Arab design is also characterized by its intricate geometric patterns, calligraphy, and use of vibrant colors. Arabic art and architecture, with their intricate geometric patterns and motifs, have influenced Arab design for centuries. Arab designers also incorporate traditional motifs, such as the paisley and the arabesque, into their work. Overall, Arab fashion elements are rooted in the rich cultural heritage of the Arab world and continue to inspire designers today. Wedding and marriage Arabic weddings have changed greatly in the past 100 years. Original traditional Arabic weddings are supposed to be very similar to modern-day Bedouin weddings and rural weddings, and they are in some cases unique from one region to another, even within the same country. The practice of marrying of relatives is a common feature of Arab culture. In the Arab world today between 40% and 50% of all marriages are consanguineous or between close family members, though these figures may vary among Arab nations. In Egypt, around 40% of the population marry a cousin. A 1992 survey in Jordan found that 32% were married to a first cousin; a further 17.3% were married to more distant relatives. 67% of marriages in Saudi Arabia are between close relatives as are 54% of all marriages in Kuwait, whereas 18% of all Lebanese were between blood relatives. Due to the actions of Muhammad and the Rightly Guided Caliphs, marriage between cousins is explicitly allowed in Islam and the Quran itself does not discourage or forbid the practice. Nevertheless, opinions vary on whether the phenomenon should be seen as exclusively based on Islamic practices as a 1992 study among Arabs in Jordan did not show significant differences between Christian Arabs or Muslim Arabs when comparing the occurrence of consanguinity. Genetics Arabs are diverse genetically as a result of their intermarriage and mixing with indigenous people of the pre-Islamic Middle East and North Africa following the Islamic expansion. Genetic ancestry components related to the Arabian peninsula display an increasing frequency pattern from west to east over North African, a similar frequency pattern exist across northeastern Africa with decreasing genetic affinities to groups of the Arabian peninsula along the Nile river valley across Sudan and South Sudan the more they go south. This genetic cline of admixture is dated to the time of Arab expansion and immigration to north and northeast Africa. In the Levant, the introduction of Islam to the region and the conversion of the region’s population to it caused major rearrangements in populations' relations and affinities through admixture with "culturally similar but geographically remote populations" with whom they enjoyed a shared Islamic culture and Arabic culture and language, which led to "genetic similarities between remarkably distant populations like Jordanians, Moroccans, and Yemenis". A 2018 study of Arabs found that peninsular Arabs genetically showed two distinct clusters and that Arabs in general can be genetically stratified into four groups; the first consisting of Maghrebis along with the first Arabian peninsula cluster, which consists of Saudis, Kuwaitis and Yemenis, the second consisting of levantine Arabs (Palestinians, Lebanese, Syrians and Jordanians) along with Egyptians and Iraqis, the third compromising Sudanis and Comorians, and the fourth compromising the second Arabian peninsula cluster consisting of Omanis, Emiratis, and Bahrainis. The study confirmed the high genetic heterogeneity among Arabs, especially those of the Arabian peninsula.

The Amstrad CPC (short for Colour Personal Computer) is a series of 8-bit home computers produced by Amstrad between 1984 and 1990. It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the ZX Spectrum, where it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe. The series spawned a total of six distinct models: The CPC 464, CPC 664, and CPC 6128 were highly successful competitors in the European home computer market. The later 464plus and 6128plus, intended to prolong the system's lifecycle with hardware updates, were considerably less successful, as was the attempt to repackage the plus hardware into a game console as the GX4000. The CPC models' hardware is based on the Zilog Z80A CPU, complemented with either 64 or 128 KB of RAM. Their computer-in-a-keyboard design prominently features an integrated storage device, either a compact cassette deck or 3-inch floppy disk drive. The main units were only sold bundled with either a colour, green-screen or monochrome monitor that doubles as the main unit's power supply. Additionally, a wide range of first and third-party hardware extensions such as external disk drives, printers, and memory extensions, was available. The CPC series was pitched against other home computers primarily used to play video games and enjoyed a strong supply of game software. The comparatively low price for a complete computer system with dedicated monitor, its high-resolution monochrome text and graphic capabilities and the possibility to run CP/M software also rendered the system attractive for business users, which was reflected by a wide selection of application software. During its lifetime, the CPC series sold approximately three million units. Models The original range The philosophy behind the CPC series was twofold, firstly the concept was of an "all-in-one", where the computer, keyboard and its data storage device were combined in a single unit and sold with its own dedicated display monitor. Most home computers at that time such as ZX Spectrum series, Commodore 64, and BBC Micro relied on the use of the domestic television set and a separately connected tape recorder or disk drive. In itself, the all-in-one concept was not new, having been seen before on business-oriented machines and the Commodore PET. Secondly, Amstrad founder Alan Sugar wanted the machine to resemble a "real computer, similar to what someone would see being used to check them in at the airport for their holidays", and for the machine to not look like "a pregnant calculator" – in reference presumably to the ZX81 and ZX Spectrum with their low cost, membrane-type keyboards. CPC 464 The CPC 464 was one of the most successful computers in Europe and sold more than two million units. The CPC 464 featured 64 KB RAM and an internal cassette deck. It was introduced in June 1984 in the UK. Initial suggested retail prices for the CPC 464 were £249.00/DM899.00 with a green screen and £359.00/DM1398.00 with a colour monitor. Following the introduction of the CPC 6128 in late 1985, suggested retail prices for the CPC 464 were cut by £50.00/DM100.00. In 1990, the 464plus replaced the CPC 464 in the model line-up, and production of the CPC 464 was discontinued. CPC 664 The CPC 664 features 64 KB RAM and an internal 3-inch floppy disk drive. It was introduced on 25 April 1985 in the UK. Initial suggested retail prices for the CPC 664 were £339.00/DM1198.00 with a green screen and £449.00/DM1998.00 with a colour monitor. After the successful release of the CPC 464, consumers were constantly asking for two improvements: more memory and an internal disk drive. For Amstrad, the latter was easier to realise. At the deliberately low-key introduction of the CPC 664, the machine was positioned not only as the lowest-cost disk system but even the lowest-cost CP/M 2.2 machine. In the Amstrad CPC product range the CPC 664 complemented the CPC 464 which was neither discontinued nor reduced in price. Compared to the CPC 464, the CPC 664's main unit has been significantly redesigned, not only to accommodate the floppy disk drive but also with a redesigned keyboard area. Touted as "ergonomic" by Amstrad's promotional material, the keyboard is noticeably tilted to the front with MSX-style cursor keys above the numeric keypad. Compared to the CPC 464's multicoloured keyboard, the CPC 664's keys are kept in a much quieter grey and pale blue colour scheme. The back of the CPC 664 main unit features the same connectors as the CPC 464, with the exception of an additional 12V power lead. Unlike the CPC 464's cassette tape drive that could be powered off the main unit's 5V voltage, the CPC 664's floppy disk drive requires an additional 12V voltage. This voltage had to be separately supplied by an updated version of the bundled green screen/colour monitor (GT-65 and CTM-644 respectively). The CPC 664 was only produced for approximately six months. In late 1985, when the CPC 6128 was introduced in Europe, Amstrad decided not to keep three models in the line-up, and production of the CPC 664 was discontinued. CPC 6128 The CPC 6128 features 128 KB RAM and an internal 3-inch floppy disk drive. Aside from various hardware and firmware improvements, one of the CPC 6128's most prominent features is the compatibility with the CP/M+ operating system that rendered it attractive for business uses. The CPC 6128 was released on 13 June 1985 and initially only sold in the US. Imported and distributed by Indescomp, Inc. of Chicago, it was the first Amstrad product to be sold in the United States, a market that at the time was traditionally hostile towards European computer manufacturers. Two months later, on 15 August 1985, it arrived in Europe and replaced the CPC 664 in the CPC model line-up. Initial suggested retail prices for the CPC 6128 were US$699.00/£299.00/DM1598.00 with a green screen and US$799.00/£399.00/DM2098.00 with a colour monitor. In 1990, the 6128plus replaced the CPC 6128 in the model line-up, and production of the CPC 6128 was discontinued. The plus range In 1990, confronted with a changing home computer market, Amstrad decided to refresh the CPC model range by introducing a new range variantly labelled plus or PLUS, 1990, or CPC+ range. The main goals were numerous enhancements to the existing CPC hardware platform, to restyle the casework to provide a contemporary appearance, and to add native support of cartridge media. The new model palette includes three variants, the 464plus and 6128plus computers and the GX4000 video game console. The "CPC" abbreviation was dropped from the model names. The redesign significantly enhanced the CPC hardware, mainly to rectify its previous shortcomings as a gaming platform. The redesigned video hardware allows for hardware sprites and soft scrolling, with a colour palette extended from a maximum of 16 colours (plus separately definable border) at one time from a choice of 27, increased to a maximum of 31 (16 for background and 15 for hardware sprites) out of 4096. The enhanced sound hardware offers automatic DMA transfer, allowing more complex sound effects with a significantly reduced processor overhead. Other hardware enhancements include the support of analogue joysticks, 8-bit printers, and ROM cartridges up to 4 Mbits. The new range of models was intended to be completely backwards compatible with the original CPC models. Its enhanced features are only available after a deliberately obscure unlocking mechanism has been triggered, thus preventing existing CPC software from accidentally invoking them. Despite the significant hardware enhancements, many viewed it as outdated, being based on an 8-bit CPU, and it failed to attract both customers and software producers who were moving towards systems such as the Commodore Amiga and Sega Mega Drive which was launched a few short months after the plus range. The plus range was a commercial failure, and production was discontinued shortly after its introduction in 1990. 464plus, 6128plus The 464plus and 6128plus models were intended as "more sophisticated and stylish" replacements of the CPC 464 and CPC 6128. Based on the redesigned plus hardware platform, they share the same base characteristics as their predecessors: The 464plus is equipped with 64 KB RAM and a cassette tape drive, the 6128plus features 128 KB RAM and a 3" floppy disk drive. Both models share a common case layout with a keyboard taken over from the CPC 6128 model, and the respective mass storage drive inserted in a case breakout. In order to simplify the EMC screening process, the edge connectors of the previous models have been replaced with micro-ribbon connectors as previously used on the German Schneider CPC 6128. As a result, a wide range of extensions for the original CPC range are connector-incompatible with the 464plus and 6128plus. In addition, the 6128plus does not have a tape socket for an external tape drive. The plus range is not equipped with an on-board ROM, and thus the 464plus and the 6128plus do not contain a firmware. Instead, Amstrad provided the firmware for both models via the ROM extension facility, contained on the included Burnin' Rubber and Locomotive BASIC cartridge. This resulted in reduced hardware localization cost (only some select key caps and case labels had to be localized) with the added benefit of a rudimentary copy protection mechanism (without a firmware present, the machine itself could not copy a game cartridge's content). As the enhanced V4 firmware's structural differences causes problems with some CPC software directly calling firmware functions by their memory addresses, Amstrad separately sold a cartridge containing the original CPC 6128's V3 firmware. Both the 464plus and the 6128plus were introduced to the public in September 1990. Initial suggested retail prices were / with a monochrome monitor and / with a colour monitor for the 464plus, and / with a monochrome monitor and / with a colour monitor for the 6128plus. GX4000 Developed as part of the plus range, the GX4000 was Amstrad's short-lived attempt to enter the video game consoles market. Sharing the plus range's enhanced hardware characteristics, it represents the bare minimum variant of the range without a keyboard or support for mass storage devices. It came bundled with 2 paddle controllers and the racing game Burnin' Rubber. Special models and clones CPC 472 During the August holidays of 1985, Spain briefly introduced an import tax of 15 000 pesetas () on computers containing 64 KB or less of RAM (Royal Decree 1215/1985 and 1558/1985), and a new law (Royal Decree 1250/1985) mandated that all computers sold in Spain must have a Spanish keyboard. To circumvent this, Amstrad's Spanish distributor Indescomp (later to become Amstrad Spain) created and distributed the CPC 472, a modified version of the CPC 464. Its main differences are a small additional daughter board containing a CPC 664 ROM chip and an 8 KB memory chip, and a keyboard with a ñ key (although some of them were temporarily manufactured without the ñ key). The sole purpose of the 8 KB memory chip (which is not electrically connected to the machine, so consequently rendered unusable) is to increase the machine's total memory specs to 72 KB in order to circumvent the import tax. Some months later, Spain joined the European Communities by the Treaty of Accession 1985 and the import tax was suppressed, so Amstrad added the ñ key for the 464 and production of the CPC472 was discontinued. KC compact The ("" - which means "small computer" - being a rather literal German translation of the English "microcomputer") is an unauthorized and unofficial clone of the Amstrad CPC built by East Germany's , part of , in October 1989. Although the machine included various substitutes and emulations of an Amstrad CPC's hardware, the machine is largely compatible with Amstrad CPC software. It is equipped with 64 KB of memory and a CPC 6128's firmware customized to the modified hardware, including a copy of Locomotive BASIC 1.1 modified in the startup banner only. The expansion port is a K 1520 bus slot. The KC compact is the last 8-bit computer introduced in East Germany. Due to the German reunification happening at the time of the release only a very small number of systems were sold. The KC compact can be emulated by free software JKCEMU. Aleste 520EX In 1993, Omsk, Russia based company Patisonic released the Aleste 520EX, a computer highly compatible with the Amstrad CPC 6128. It could also be switched into an MSX mode. An expansion board named Magic Sound allowed to play Scream Tracker files. Reception A BYTE columnist in January 1985 called the CPC 464 "the closest yet to filling" his criteria for a useful home computer, including good keyboard, 80-column text, inexpensive disk drive, and support for a mainstream operating system like CP/M. Hardware Processor The entire CPC series is based on the Zilog Z80; a processor, clocked at 4 MHz. In order to avoid the CPU and the video logic simultaneously accessing the shared main memory and causing video corruption ("snowing"), CPU memory access is constrained to occur on microsecond boundaries. This effectively pads every machine cycle to four clock cycles, causing a minor loss of processing power and resulting in what Amstrad estimated to be an "effective clock rate" of "approximately 3.3 MHz". Memory Amstrad CPCs are equipped with either 64 (CPC 464, CPC 664, 464plus, GX4000) or 128 (CPC 6128, 6128plus) KB of RAM. This base memory can be extended by up to 512 KB using memory expansions sold by third-party manufacturers, and by up to 4096 KB using experimental methods developed by hardware enthusiasts. Because the Z80 processor is only able to directly address 64 KB of memory, additional memory from the 128 KB models and memory expansions is made available using bank switching. Video Underlying a CPC's video output is the unusual pairing of a CRTC (Motorola 6845 or compatible) with a custom-designed gate array to generate a pixel display output. CPC 6128s later in production as well as the models from the plus range integrate both the CRTC and the gate array's functions with the system's ASIC. Three built-in display resolutions are available: 160×200 pixels with 16 colours ("Mode 0", 20 text columns), 320×200 pixels with 4 colours ("Mode 1", 40 text columns), and 640×200 pixels with 2 colours ("Mode 2", 80 text columns). Increased screen size can be achieved by reprogramming the CRTC. The original CPC video hardware supports a colour palette of 27 colours, generated from RGB colour space with each colour component assigned as either off, half on, or on (3 level RGB palette). The plus range extended the palette to 4096 colours, also generated from RGB with 4 bits each for red, green and blue (12-bit RGB). With the exception of the GX4000, all CPC models lack an RF television or composite video output and instead shipped with a 6-pin RGB DIN connector, also used by Acorn computers, to connect the supplied Amstrad monitor. This connector delivers a 1v p-p analogue RGB with a 50 Hz composite sync signal that, if wired correctly, can drive a 50 Hz SCART television. External adapters for RF television were available as a first-party hardware accessory. Audio The CPC uses the General Instrument AY-3-8912 sound chip, providing three channels, each configurable to generate square waves, white noise or both. A small array of hardware volume envelopes are available. Output is provided in mono by a small (4 cm) built-in loudspeaker with volume control, driven by an internal amplifier. Stereo output is provided through a headphones jack. It is possible to play back digital sound samples at a resolution of approximately 5-bit by sending a stream of values to the sound chip. This technique is very processor-intensive and hard to combine with any other processing. Examples are the title screens or other non-playable scenes of games like Chase H.Q., Meltdown, and RoboCop. The later Plus models incorporated a DMA engine in order to offload this processing. Floppy disk drive Amstrad uses Matsushita's 3" floppy disk drive [ref: CPCWiki], which was compatible with Hitachi's existing 3" floppy disk format. The chosen drive (built-in for later models) is a single-sided 40-track unit that requires the user to remove and flip the disk to access the other side. Each side has its own independent write-protect switch. The sides are termed "A" and "B", with each one commonly formatted to 180 KB (in AMSDOS format, comprising 2 KB directory and 178 KB storage) for a total of 360 KB per disk. The interface with the drives is an NEC 765 FDC, used for the same purpose in the IBM PC/XT, PC/AT and PS/2 machines. Its features are not fully used in order to cut costs, namely DMA transfers and support for single density disks; they were formatted as double density using modified frequency modulation. Discs were shipped in a paper sleeve or a hard plastic case resembling a compact disc "jewel" case. The casing is thicker and more rigid than that of 3.5 inch diskettes, and designed to be mailed without any additional packaging. A sliding metal cover to protect the media surface is internal to the casing and latched, unlike the simple external sliding cover of Sony's version. They were significantly more expensive than both 5.25 inch and 3.5 inch alternatives. This, combined with their low nominal capacities and their essentially proprietary nature, led to the format being discontinued shortly after the CPC itself was discontinued. Apart from Amstrad's other 3-inch machines (the PCW and the ZX Spectrum +3), the few other computer systems to use them included the Sega SF-7000 and CP/M systems such as the Tatung Einstein and Osborne machines. They also found use on embedded systems. The Shugart-standard interface means that Amstrad CPC machines are able to use standard 3", 3½" or 5¼" drives as their second drive. Programs such as ROMDOS and ParaDOS extend the standard AMSDOS system to provide support for double-sided, 80-track formats, enabling up to 800 KB to be stored on a single disk. The 3-inch disks themselves are usually known as "discs" on the CPC, following the spelling on the machine's plastic casing and conventional British English spelling. Expansion The hardware and firmware was designed to be able to access software provided on external ROMs. Each ROM has to be a 16 KB block and is switched in and out of the memory space shared with the video RAM. The Amstrad firmware is deliberately designed so that new software could be easily accessed from these ROMs. Popular applications were marketed on ROM, particularly word processing and programming utility software (examples are Protext and Brunword of the former, and the MAXAM assembler of the latter type). Such extra ROM chips do not plug directly into the CPC itself, but into extra plug-in "rom boxes" which contain sockets for the ROM chips and a minimal amount of decoding circuitry for the main machine to be able to switch between them. These boxes were either marketed commercially or could be built by competent hobbyists and they attached to the main expansion port at the back of the machine. Software on ROM loads much faster than from disc or tape and the machine's boot-up sequence was designed to evaluate ROMs it found and optionally hand over control of the machine to them. This allows significant customisation of the functionality of the machine, something that enthusiasts exploited for various purposes. However, the typical users would probably not be aware of this added ROM functionality unless they read the CPC press, as it is not described in the user manual and was hardly ever mentioned in marketing literature. It is, however, documented in the official Amstrad firmware manual. The machines also feature a 9-pin Atari joystick port that will either directly take one joystick, or two joysticks by use of a splitter cable. Peripherals RS232 serial adapters Amstrad issued two RS-232-C D25 serial interfaces, attached to the expansion connector on the rear of the machine, with a through-connector for the CPC 464 disk drive or other peripherals. The original interface came with a Book of Spells for facilitating data transfer between other systems using a proprietary protocol in the device's own ROM, as well as terminal software to connect to British Telecom's Prestel service. A separate version of the ROM was created for the U.S. market due to the use of the commands "|SUCK" and "|BLOW", which were considered unacceptable there. Software and hardware limitations in this interface led to its replacement with an Amstrad-branded version of a compatible alternative by Pace. Serial interfaces were also available from third-party vendors such as KDS Electronics and Cirkit. Software BASIC and operating system Like most home computers at the time, the CPC has its OS and a BASIC interpreter built in as ROM. It uses Locomotive BASIC - an improved version of Locomotive Software's Z80 BASIC for the BBC Micro co-processor board. It is particularly notable for providing easy access to the machine's video and audio resources in contrast to the POKE commands required on generic Microsoft implementations. Other unusual features include timed event handling with the AFTER and EVERY commands, and text-based windowing. CP/M Digital Research's CP/M operating system was supplied with the 664 and 6128 disk-based systems, and the DDI-1 disk expansion unit for the 464. 64k machines shipped with CP/M 2.2 alone, while the 128k machines also include CP/M 3.1. The compact CP/M 2.2 implementation is largely stored on the boot sectors of a 3" disk in what was called "System format"; typing |CPM from Locomotive BASIC would load code from these sectors, making it a popular choice for custom game loading routines. The CP/M 3.1 implementation is largely in a separate file which is in turn loaded from the boot sector. Much public domain CP/M software was made available for the CPC, from word-processors such as VDE to complete bulletin board systems such as ROS. Other languages Although it was possible to obtain compilers for Locomotive BASIC, C and Pascal, the majority of the CPC's software was written in native Z80 assembly language. Popular assemblers were Hisoft's Devpac, Arnor's Maxam, and (in France) DAMS. Disk-based CPC (not Plus) systems shipped with an interpreter for the educational language LOGO, booted from CP/M 2.2 but largely CPC-specific with much code resident in the AMSDOS ROM; 6128 machines also include a CP/M 3.1, non-ROM version. A C compiler was also written and made available for the European market through Tandy Europe, by Micro Business products. Roland In an attempt to give the CPC a recognisable mascot, a number of games by Amstrad's in-house software publisher Amsoft have been tagged with the Roland name. However, as the games had not been designed around the Roland character and only had the branding added later, the character design varies immensely, from a spiky-haired blonde teenager (Roland Goes Digging) to a white cube with legs (Roland Goes Square Bashing) or a mutant flea (Roland in the Caves). The only two games with similar gameplay and main character design are Roland in Time and its sequel Roland in Space. The Roland character was named after Roland Perry, one of the lead designers of the original CPC range. Schneider Computer Division In order to market its computers in Germany, Austria, and Switzerland where Amstrad did not have any distribution structures, Amstrad entered a partnership with Schneider Rundfunkwerke AG, a German company that - very much like Amstrad itself - was previously only known for value-priced audio products. In 1984, Schneider's Schneider Computer Division daughter company was created specifically for the task, and the complete Amstrad CPC line-up was branded and sold as Schneider CPC. Although they are based on the same hardware, the Schneider CPC models differ from the Amstrad CPC models in several details. Most prominently, the Schneider CPC 464 and CPC 664 keyboards featured grey instead of coloured keys, but still in the original British keyboard layout. To achieve a German "QWERTZ" keyboard layout, Schneider marketed a small software program to reassign the keys as well as sticker labels for the keys. In order to conform with stricter German EMC regulations, the complete Schneider CPC line-up is equipped with an internal metal shielding. For the same reason, the Schneider CPC 6128 features micro ribbon type connectors instead of edge connectors. Both the greyscale keyboard and the micro ribbon connectors found their way up into the design of later Amstrad CPC models. In 1988, after Schneider refused to market Amstrad's AT-compatible computer line, the cooperation ended. Schneider went on to sell the remaining stock of Schneider CPC models and used their now well-established market position to introduce its own PC designs. With the formation of its German daughter company Amstrad GmbH to distribute its product lines including the CPC 464 and CPC 6128, Amstrad attempted but ultimately failed to establish their own brand in the German-speaking parts of Europe. Community The Amstrad CPC enjoyed a strong and long lifetime, mainly due to the machines use for businesses as well as gaming. Dedicated programmers continued working on the CPC range, even producing graphical user interface (GUI) operating systems such as SymbOS. Internet sites devoted to the CPC have appeared from around the world featuring forums, news, hardware, software, programming and games. CPC Magazines appeared during the 1980s including publications in countries such as Britain, France, Spain, Germany, Denmark, Australia, and Greece. Titles included the official Amstrad Computer User publication, as well as independent titles like Amstrad Action, Amtix!, Computing with the Amstrad CPC, CPC Attack, Australia's The Amstrad User, France's Amstrad Cent Pour Cent and Amstar. Following the CPC's end of production, Amstrad gave permission for the CPC ROMs to be distributed freely as long as the copyright message is not changed and that it is acknowledged that Amstrad still holds copyright, giving emulator authors the possibility to ship the CPC firmware with their programs. Influence on other Amstrad machines Amstrad followed their success with the CPC 464 by launching the Amstrad PCW word-processor range, another Z80-based machine with a 3" disk drive and software by Locomotive Software. The PCW was originally developed to be partly compatible with an improved version of the CPC (ANT, or Arnold Number Two - the CPC's development codename was Arnold). However, Amstrad decided to focus on the PCW, and the ANT project never came to market. On 7 April 1986, Amstrad announced it had bought from Sinclair Research "...the worldwide rights to sell and manufacture all existing and future Sinclair computers and computer products, together with the Sinclair brand name and those intellectual property rights where they relate to computers and computer-related products." which included the ZX Spectrum, for £5 million. This included Sinclair's unsold stock of Sinclair QLs and Spectrums. Amstrad made more than £5 million on selling these surplus machines alone. Amstrad launched two new variants of the Spectrum: the ZX Spectrum +2, based on the ZX Spectrum 128, with a built-in tape drive (like the CPC 464) and, the following year, the ZX Spectrum +3, with a built-in floppy disk drive (similar to the CPC 664 and 6128), taking the 3" discs that Amstrad CPC machines used.

American folklore encompasses the folklores that have evolved in the present-day United States since Europeans arrived in the 16th century. While it contains much in the way of Native American tradition, it is not wholly identical to the tribal beliefs of any community of native people. Folklore consists of legends, music, oral history, proverbs, jokes, popular beliefs, fairy tales, stories, tall tales, and customs that are the traditions of a culture, subculture, or group. It is also the set of practices through which those expressive genres are shared. Native American folklore Native American cultures are rich in myths and legends that explain natural phenomena and the relationship between humans and the spirit world. According to Barre Toelken, feathers, beadwork, dance steps and music, the events in a story, the shape of a dwelling, or items of traditional food can be viewed as icons of cultural meaning. Native American cultures are numerous and diverse. Though some neighboring cultures hold similar beliefs, others can be quite different from one another. The most common myths are the creation myths, which tell a story to explain how the earth was formed, and where humans and other beings came from. Others may include explanations about the Sun, Moon, constellations, specific animals, seasons, and weather. This is one of the ways that many tribes have kept, and continue to keep, their cultures alive; these stories are told as a way of preserving and transmitting the nation, tribe, or band's particular beliefs, history, customs, spirituality, and traditional way of life. According to Barre Toelken, "Stories not only entertain but also embody Native behavioral and ethical values." Although individual tribes have their own sacred beliefs and myths, many stories have much in common. Myths about floods are almost universal amongst Plains tribes, stories of a flooded earth being restored. There are many "hero stories" immortalising the adventures of heroes with supernatural powers, who right wrongs and defeat evils. Animal tales are common, some explaining how features of certain animals occurred, some using animal characters for narration, and others using animals symbolically. There are also myths where supernatural beings appear in the form of animals, with the bear, elk, eagle, owl, and snake frequently referred to. Founding myths The founding of the United States is often surrounded by legends and tall tales. Many stories have developed since the founding long ago to become a part of America's folklore and cultural awareness, and non-Native American folklore especially includes any narrative which has contributed to the shaping of American culture and belief systems. These narratives have varying levels of historical accuracy; the veracity of the stories is not a determining factor. Christopher Columbus Christopher Columbus, as a hero and symbol to the then-immigrants, is an important figure in the body of American myth. His status, not unlike most American icons, is representative not of his own accomplishments, but the self-perception of the society which chose him as a hero. Having effected a separation from England and its cultural icons, the United States was left without history—or heroes on which to base a shared sense of their social selves. Washington Irving was instrumental in popularizing Columbus. His version of Columbus' life, published in 1829, was more a romance than a biography. The book was very popular, and contributed to an image of the discoverer as a solitary individual who challenged the unknown sea, as triumphant Americans contemplated the dangers and promise of their own wilderness frontier. As a consequence of his vision and audacity, there was now a land free from kings, a vast continent for new beginnings. In the years following the Revolution the poetic device "Columbia" was used as a symbol of both Columbus and America. King's College of New York changed its name in 1792 to Columbia, and the new capital in Washington was subtitled District of Columbia. Jamestown In May 1607, the Susan Constant, the Discovery, and the Godspeed sailed through Chesapeake Bay and thirty miles up the James River settlers built Jamestown, Virginia, England's first permanent colony. Too late in the season to plant crops, many were not accustomed to manual labor. Within a few months, some settlers died of famine and disease. Only thirty-eight made it through their first year in the New World. Captain John Smith, a pirate turned gentleman turned the settlers into foragers and successful traders with the Native Americans, who taught the English how to plant corn and other crops. Smith led expeditions to explore the regions surrounding Jamestown, and it was during one of these that the chief of the Powhatan Native Americans captured Smith. According to an account Smith published in 1624, he was going to be put to death until the chief's daughter, Pocahontas, saved him. From this the legend of Pocahontas sprang forth, becoming part of American folklore, children's books, and movies. Pilgrims Plymouth Rock is the traditional site of disembarkation of William Bradford and the Mayflower Pilgrims who founded Plymouth Colony in 1620, and an important symbol in American history. There are no contemporary references to the Pilgrims' landing on a rock at Plymouth. The first written reference to the Pilgrims landing on a rock is found 121 years after they landed. The Rock, or one traditionally identified as it, has long been memorialized on the shore of Plymouth Harbor in Plymouth, Massachusetts. The holiday of Thanksgiving is said to have begun with the Pilgrims in 1621. They had come to America to escape religious persecution, but then nearly starved to death. Some friendly Native Americans, including Squanto, helped the Pilgrims survive through the first winter. The perseverance of the Pilgrims is celebrated during the annual Thanksgiving festival. Revolutionary War figures George Washington George Washington (February 22, 1732 – December 14, 1799), the country's first president, is the most preeminent of American historical and folkloric figures, as he holds the place of "Pater Patriae". Apocryphal stories about Washington's childhood include a claim that he skipped a silver dollar across the Rappahannock River at Ferry Farm. Another tale claims that as a young child, Washington chopped down his father's cherry tree. His angry father confronted the young Washington, who proclaimed "I cannot tell a lie" and admitted to the transgression, thus illuminating his honesty. Parson Mason Locke Weems mentions the first citation of this legend in his 1806 book, The Life of George Washington: With Curious Anecdotes, Equally Honorable to Himself and Exemplary to His Young Countrymen. This anecdote cannot be independently verified. Samuel Clemens, also known as Mark Twain, is also known to have spread the story while lecturing, personalizing it by adding "I have a higher and greater standard of principle. Washington could not lie. I can lie but I won't." Patrick Henry Patrick Henry (May 29, 1736 – June 6, 1799) was an attorney, planter and politician who became known as an orator during the movement for independence in Virginia in the 1770s. Patrick Henry is best known for the speech he made in the House of Burgesses on March 23, 1775, in Saint John's Church in Richmond, Virginia. With the House undecided on whether to mobilize for military action against the encroaching British military force, Henry argued in favor of mobilization. Forty-two years later, Henry's first biographer, William Wirt, working from oral histories, tried to reconstruct what Henry said. According to Wirt, Henry ended his speech with words that have since become immortalized: "I know not what course others may take; but as for me, Give me Liberty, or give me Death!" The crowd, by Wirt's account, jumped up and shouted "To Arms! To Arms!". For 160 years Wirt's account was taken at face value. In the 1970s, historians began to question the authenticity of Wirt's reconstruction. Betsy Ross Betsy Ross (January 1, 1752 – January 30, 1836) is widely credited with making the first American flag. There is, however, no credible historical evidence that the story is true. Research conducted by the National Museum of American History notes that the story of Betsy Ross making the first American flag for General George Washington entered into American consciousness about the time of the 1876 centennial celebrations. In the 2008 book The Star-Spangled Banner: The Making of an American Icon, Smithsonian experts point out that accounts of the event appealed to Americans eager for stories about the revolution and its heroes and heroines. Betsy Ross was promoted as a patriotic role model for young girls and a symbol of women's contributions to American history. Other Revolutionary War heroes who became figures of American folklore include: Benedict Arnold, Benjamin Franklin, Nathan Hale, John Hancock, John Paul Jones and Francis Marion. Tall tales The tall tale is a fundamental element of American folk literature. The tall tale's origins are seen in the bragging contests that often occurred when men of the American frontier gathered. A tall tale is a story with unbelievable elements, relayed as if it were true and factual. Some such stories are exaggerations of actual events; others are completely fictional tales set in a familiar setting, such as the American Old West, or the beginning of the Industrial Revolution. They are usually humorous or good-natured. The line between myth and tall tale is distinguished primarily by age; many myths exaggerate the exploits of their heroes, but in tall tales, the exaggeration looms large, to the extent of becoming the whole of the story. Based on historical figures John Chapman (September 26, 1774 – March 18, 1845), widely known as Johnny Appleseed, was an American pioneer nurseryman who introduced apple trees to large parts of Pennsylvania, Ohio, Indiana, and Illinois. He became an American legend while still alive, largely because of his kind and generous ways, and the symbolic importance he attributed to apples. Johnny Appleseed is remembered in American popular culture by his traveling song or Swedenborgian hymn ("The Lord is good to me..."). Daniel Boone (November 2, 1734 [O.S. October 22] – September 26, 1820) was an American pioneer, explorer, and frontiersman whose frontier exploits made him one of the first folk heroes of the United States. Davy Crockett (August 17, 1786 – March 6, 1836) was a 19th-century American folk hero, frontiersman, soldier and politician. He is commonly referred to in popular culture by the epithet, "King of the Wild Frontier". He represented Tennessee in the U.S. House of Representatives, served in the Texas Revolution, and died at the Battle of the Alamo. Mike Fink (c. 1770/1780 – c. 1823) called "king of the keelboaters", was a semi-legendary brawler and river boatman who exemplified the tough and hard-drinking men who ran keelboats up and down the Ohio and Mississippi Rivers. Martha Jane Canary (May 1, 1852 – August 1, 1903), better known as Calamity Jane, was an American frontierswoman, and professional scout best known for her claim of being an acquaintance of Wild Bill Hickok. She is said to have also exhibited kindness and compassion, especially to the sick and needy. It was from her that Bret Harte took his famous character of Cherokee Sal in The Luck of Roaring Camp. Jigger Johnson (1871–1935), was a lumberjack and log driver from northern New England who is known for his numerous off-the-job exploits, such as catching bobcats alive with his bare hands, and drunken brawls. John Henry was an African-American railroad worker who is said to have worked as a "steel-driving man"—a man tasked with hammering a steel drill into rock to make holes for explosives to blast the rock away in constructing a railroad tunnel. According to legend, John Henry's prowess as a steel-driver was measured in a race against a steam-powered hammer, which he won, only to die in victory with his hammer in his hand and his heart giving out from stress. The "Ballad of John Henry" is a musical rendition of his story. Molly Pitcher was a nickname given to a woman said to have fought in the American Battle of Monmouth, who is generally believed to have been Mary Hays. Since various Molly Pitcher tales grew in the telling, many historians regard Molly Pitcher as folklore rather than history, or suggest that Molly Pitcher may be a composite image inspired by the actions of a number of real women. The name itself may have originated as a nickname given to women who carried water to men on the battlefield during the war. Other historical figures include Titanic survivor Molly Brown, Wild West showman Buffalo Bill Cody, and sharpshooter Annie Oakley. Fictional characters Paul Bunyan is a lumberjack figure in North American folklore and tradition. One of the most famous and popular North American folklore heroes, he is usually described as a giant as well as a lumberjack of unusual skill, and is often accompanied in stories by his animal companion, Babe the Blue Ox. The character originated in folktales circulated among lumberjacks in the Northeastern United States and eastern Canada, first appearing in print in a story published by Northern Michigan journalist James MacGillivray in 1906. Cordwood Pete is said to be the younger brother of legendary lumberjack Paul Bunyan. The Lone Ranger is a fictional hero of the west who fought raiders and robbers in the Texas area. The sole survivor of a group of six rangers, he set out to bring the criminals who killed his brother to justice. The Lone Ranger is said to have been based on Bass Reeves by Historian Art Burton but that is in dispute. Johnny Kaw is a mythical Kansas settler whose exploits created elements of the Kansas landscape and helped establish wheat and sunflowers as major crops. The character dates to the 1955 centennial of Kansas and has been explored in numerous books. John the Conqueror also known as High John the Conqueror, and many other folk variants, is a folk hero from African-American folklore. John the Conqueror was an African prince who was sold as a slave in the Americas. Despite his enslavement, his spirit was never broken and he survived in folklore as a sort of a trickster figure, because of the tricks he played to evade his masters. Joel Chandler Harris's 'Br'er Rabbit' of the Uncle Remus stories is said to be patterned after High John the Conqueror. Pecos Bill is an American cowboy, apocryphally immortalized in numerous tall tales of the Old West during American westward expansion into the Southwest of Texas, New Mexico, Southern California, and Arizona Captain Stormalong was an American folk hero and the subject of numerous nautical-themed tall tales originating in Massachusetts. Stormalong was said to be a sailor and a giant, some 30 feet tall; he was the master of a huge clipper ship known in various sources as either the Courser or the Tuscarora, a ship so tall that it had hinged masts to avoid catching on the moon. Legendary and folkloric creatures Bigfoot, also known as "Sasquatch", is the name given to an ape-like creature that some believe inhabit mostly forests in the Pacific Northwest region of, and throughout the entirety of, North America. Bigfoot is usually described as a large, hairy, bipedal humanoid, although descriptions vary depending on location. The height range is about 6 to 10 feet tall with black, dark brown, or dark reddish hair. One of the most famous accounts of Bigfoot is the Patterson-Gimlin film, where a supposedly female Bigfoot marches across the screen with giant strides, turns to face the camera, then marches off up a steep hill and into the forest. There are more than 100 sightings reported yearly. Among these reporters are veterans, campers, hikers, explorers, hunters, and more. There are several websites, podcasts and organizations related to Bigfoot. Champ is the name given to a reputed lake monster living in Lake Champlain, a natural freshwater lake in North America. The lake crosses the Canada–United States border, located partially in the Canadian province of Quebec and partially in the U.S. states of Vermont and New York. There is no scientific evidence for Champ's existence, though there have been over 300 reported sightings. Punxsutawney Phil is a semi-mythical groundhog central to the most well-known Groundhog Day ceremony, a Pennsylvania Dutch superstition that claims to predict the arrival of spring. According to tradition, the same groundhog has made predictions ever since the 1800s. The Jersey Devil is a legendary creature said to inhabit the New Jersey Pine Barrens of Southern New Jersey in the United States. The creature is often described as a flying biped with hooves, but there are many different variations. The most common description is that of a kangaroo-like creature with the face of a horse, the head of a dog, leathery bat-like wings, horns, small arms with clawed hands, red eyes, cloven hooves and a forked tail. It has been reported to move quickly, as to avoid human contact, and often is described as emitting a "blood-curdling scream". The legend goes as such: a woman named Mother Leeds gave birth to her 13th child on a dark, stormy night. Mother Leed is said to be a witch and her 13th child was born the Devil. It soon grew wings and hooves, killed the midwife, and took off into the night. The White Lady is a type of female ghost reportedly seen in rural areas and associated with some local legend of tragedy. Common to many of them is the theme of losing or being betrayed by a husband or fiancé. They are often associated with an individual family line or said to be a harbinger of death, similar to a banshee. Mothman is a mythical creature from Point Pleasant, West Virginia described as a large humanoid with glowing red eyes on its face and large bird-like wings with fur covering its body. Mothman has been blamed for the collapse of the Silver Bridge. The Hodag is a mythical beast that is said to inhabit the forests of Northern Wisconsin, particularly around the city of Rhinelander. The Hodag has a reptilian body with the horns of a bull and is said to have a penchant for mischief. Old Black Eyes is a spectral hound said to frequent an area known as the Baker Rocks, located near the top of the Black Mountains of North Carolina. Old Black Eyes is said to be the spirit of Jim Baker, who lived at the rocks and was regarded as a witch with supernatural powers by the local mountain people. According to legend, Jim Baker performed some sort of ritual at an old Indian cemetery, near the Black Mountains, where he proceeded to sell his soul to the Devil. The Devil proceeded to turn Baker's pupils "unnaturally black" as a sign of their deal and hell's claim on his soul. Upon his death, Baker was said to take the spirit of a "devil dog", identifiable by the large black pupils of its eyes, that people feared to approach, believing it was surrounded in black magic. It was said the only way to get rid of Old Black Eyes was to draw its picture, pin it to a tree, and then shoot it with a gun. In North American folklore, Fearsome critters were tall tale animals jokingly said to inhabit the wilderness in or around logging camps, especially in the Great Lakes region. Today, the term may also be applied to similar fabulous beasts. Other folkloric creatures include the Chupacabra, Jackalope, the Nain Rouge of Detroit, Michigan, Wendigo of Minnesota and Chessie, a legendary sea monster said to live in Chesapeake Bay. Literature Santa Claus, also known as Saint Nicholas, Father Christmas, or simply "Santa", is a figure with legendary, mythical, historical and folkloric origins. The modern figure of Santa Claus was derived from the Dutch figure, Sinterklaas, which may, in turn, have its origins in the hagiographical tales concerning the Christian Saint Nicholas. "A Visit from St. Nicholas", also known as "The Night Before Christmas" is a poem first published anonymously in 1823 and generally attributed to Clement Clarke Moore. The poem, which has been called "arguably the best-known verses ever written by an American", is largely responsible for the conception of Santa Claus from the mid-nineteenth century to today, including his physical appearance, the night of his visit, his mode of transportation, the number and names of his reindeer, as well as the tradition that he brings toys to children. The poem has influenced ideas about St. Nicholas and Santa Claus from the United States to the rest of the English-speaking world and beyond. Is There a Santa Claus? was the title of an editorial appearing in the September 21, 1897, edition of The (New York) Sun. The editorial, which included the famous reply "Yes, Virginia, there is a Santa Claus", has become a part of popular Christmas folklore in the United States and Canada. The Headless Horseman is a fictional character from the short story "The Legend of Sleepy Hollow" by American author Washington Irving. The story, from Irving's collection of short stories, entitled The Sketch Book of Geoffrey Crayon, has worked itself into known American folklore/legend through literature and film. "Rip Van Winkle" is a short story by the American author Washington Irving, first published in 1819. It follows a Dutch-American villager in colonial America named Rip Van Winkle who meets mysterious Dutchmen, imbibes their liquor and falls asleep in the Catskill Mountains. He awakes 20 years later to a very changed world, having missed the American Revolution. Inspired by a conversation on nostalgia with his American expatriate brother-in-law, Irving wrote the story while temporarily living in Birmingham, England. It was published in his collection, The Sketch Book of Geoffrey Crayon, Gent. While the story is set in New York's Catskill Mountains near where Irving later took up residence, he admitted, "When I wrote the story, I had never been on the Catskills." Folk music Native Americans were the earliest inhabitants of the land that is today known as the United States and played its first music. Beginning in the 17th century, immigrants from the United Kingdom, Ireland, Spain, Germany and France began arriving in large numbers, bringing with them new styles and instruments. African slaves brought musical traditions, and each subsequent wave of immigrants contributes to a melting pot. Folk music includes both traditional music and the genre that evolved from it during the 20th-century folk revival. The term originated in the 19th century but is often applied to music that is older than that. The earliest American scholars were with The American Folklore Society (AFS), which emerged in the late 1800s. Their studies expanded to include Native American music but still treated folk music as a historical item preserved in isolated societies. In North America, during the 1930s and 1940s, the Library of Congress worked through the offices of traditional music collectors Robert Winslow Gordon, Alan Lomax and others to capture as much North American field material as possible. Lomax was the first prominent scholar to study distinctly American folk music such as that of cowboys and southern blacks. His first major published work was in 1911, Cowboy Songs and Other Frontier Ballads, and was arguably the most prominent US folk music scholar of his time, notably during the beginnings of the folk music revival in the 1930s and early 1940s. The American folk music revival was a phenomenon in the United States that began during the 1940s and peaked in popularity in the mid-1960s. Its roots went earlier, and performers like Burl Ives, Woody Guthrie, Lead Belly, and Oscar Brand had enjoyed a limited general popularity in the 1930s and 1940s. The revival brought forward musical styles that had, in earlier times, contributed to the development of country & western, jazz, and rock and roll music. African-American music Slavery was introduced to the Thirteen Colonies beginning in the early 17th century in Virginia. The ancestors of today's African-American population were brought from hundreds of tribes across West Africa and brought with them certain traits of West African music. This included call and response vocals, complex rhythmic music, syncopated beats, shifting accents, incorporation of hums and moans, which are sounds with no distinct meaning, and a combination of sound and body movements. The African musical focus on rhythmic singing and dancing was brought to the New World, where it became part of a distinct folk culture that helped Africans "retain continuity with their past through music." Along with retaining many African elements, there was also a continuation of instruments. Enslaved Africans would either take with them African instruments or reconstructed them once in the New World. The first slaves in the United States sang work songs and field hollers. However, slave music was used for a variety of reasons. Music was included in religious ceremonies and celebrations, used to coordinate work, and to conceal hidden messages, like when they were commenting on slave owners. African American slave songs can be divided into three groups: religious, work, and recreational songs. Spirituals Protestant hymns written mostly by New England preachers became a feature of camp meetings held among devout Christians across the South. Most slaves were typically animists or were a part of some other form of African Religion. To destroy any remnants of African culture or make more people disciples, slaves would be encouraged and taken to church. They became attracted to the grace and freedom that was preached within the church, which was very different from the lives they were living. Slaves would learn the same hymns that their masters sang, and when they came together they developed and sang adapted versions of these hymns, they were called Negro spirituals. It was from these roots, of spiritual songs, work songs, and field hollers, that blues, jazz, and gospel developed. Negro spirituals were primarily expressions of religious faith. These songs provided them a voice for their longing for freedom and to experience it. Around the 1840s, slaves knew that in the northern states, slavery was illegal, and some northerners wanted the complete abolishment of slavery. So when they sang about heaven, it was also about possibly escaping north. In the early 19th century the Underground Railroad was developed, containing a network of secret routes and safe houses, and it greatly impacted slaves' religious music. When there was any mention of trains, stations, etc. in spirituals they were directly referencing the Underground Railroad, such as the song "Swing Low, Sweet Chariot". These songs were designed so that slave owners thought that slaves were only singing about heaven. Work songs Work Songs at least had two functions: one to benefit the slaves and another to benefit overseers. When a group of slaves had to work together on a hard task, like carrying a heavy load, singing would provide a rhythm that allowed them to coordinate their movements. When picking crops, music was not necessary, but when there was silence it would be uncomfortable for the overseers. Even though there was a presence of melancholy in songs, Southern slave owners would interpret that their slaves were happy and content, possibly because of their singing. Recreational songs Even if slave owners attempted to forbid things like drums or remnants of African culture, they did not seem to mind them learning European instruments and music. In some cases, black string players would be invited to play to entertain white audiences. Between the week of Christmas and New Years’, owners would give their slaves a holiday. This provided a chance for slave families who had different masters to come together, otherwise, they would not go anywhere. Some slaves would craft items, but masters detested industrious slaves. So most slaves would spend their recreational time doing other things, like dancing and singing. Masters approved of such activities, but they may not have listened carefully to the songs that were performed. Folk songs The original Thirteen Colonies of the United States were all former British possessions, and Anglo culture became a major foundation for American folk and popular music. Many American folk songs are identical to British songs in arrangements, but with new lyrics, often as parodies of the original material. Anglo-American traditional music also includes a variety of broadside ballads, humorous stories and tall tales, and disaster songs regarding mining, shipwrecks and murder. Folk songs may be classified by subject matter, such as: drinking songs, sporting songs, train songs, work songs, war songs, and ballads. The Star-Spangled Banner's tune was adapted from an old English drinking song by John Stafford Smith called "To Anacreon in Heaven." "The Ballad of Casey Jones" is a traditional song about railroad engineer Casey Jones and his death at the controls of the train he was driving. It tells of how Jones and his fireman Sim Webb raced their locomotive to make up for lost time, but discovered another train ahead of them on the line, and how Jones remained on board to try to stop the train as Webb jumped to safety. "When Johnny Comes Marching Home" (sometimes "When Johnny Comes Marching Home Again") is a popular song of the American Civil War that expressed people's longing for the return of their friends and relatives who were fighting in the war. The Irish anti-war song "Johnny I Hardly Knew Ye" and "When Johnny Comes Marching Home" share the same melodic material. Based on internal textual references, "Johnny I Hardly Knew Ye" apparently dates from the early 1820s, while When Johnny Comes Marching Home was first published in 1863. "Johnny I Hardly Knew Ye" is a popular traditional Irish anti-war and anti-recruiting song. It is generally dated to the early 19th century, when soldiers from Athy, County Kildare served the British East India Company. "Oh My Darling, Clementine" (1884) is an American western folk ballad believed to have been based on another song called Down by the River Liv'd a Maiden (1863). The words are those of a bereaved lover singing about his darling, the daughter of a miner in the 1849 California Gold Rush. He loses her in a drowning accident. The song plays during the opening credits for the highly acclaimed John Ford movie "My Darling Clementine". It also runs as a background score all through the movie. The Yellow Rose of Texas is a traditional folk song. The original love song has become associated with the legend that Emily D. West, a biracial indentured servant, "helped win the Battle of San Jacinto, the decisive battle in the Texas Revolution". "Take Me Out to the Ball Game" is a 1908 Tin Pan Alley song by Jack Norworth and Albert Von Tilzer which has become the unofficial anthem of baseball, although neither of its authors had attended a game prior to writing the song. The song is traditionally sung during the seventh-inning stretch of a baseball game. Fans are generally encouraged to sing along. Other American folksongs include: "She'll Be Coming 'Round the Mountain", "Skewball", "Big Bad John", "Stagger Lee", "Camptown Races" and "The Battle Hymn of the Republic". Sea shanties Work songs sung by sailors between the 18th and 20th centuries are known as sea shanties. The shanty was a distinct type of work song, developed especially in American-style merchant vessels that had come to prominence in decades prior to the American Civil War. These songs were typically performed while adjusting the rigging, raising anchor, and other tasks where men would need to pull in rhythm. These songs usually have a very punctuated rhythm precisely for this reason, along with a call-and-answer format. Well before the 19th century, sea songs were common on rowing vessels. Such songs were also very rhythmic in order to keep the rowers together. They were notably influenced by songs of African Americans, such as those sung whilst manually loading vessels with cotton in ports of the southern United States. The work contexts in which African-Americans sang songs comparable to shanties included: boat-rowing on rivers of the southeastern U.S. and Caribbean; the work of stokers or "firemen", who cast wood into the furnaces of steamboats plying great American rivers;and stevedoring on the U.S. eastern seaboard, the Gulf Coast, and the Caribbean—including "cotton-screwing": the loading of ships with cotton in ports of the American South. During the first half of the 19th century, some of the songs African Americans sang also began to appear in use for shipboard tasks, i.e. as shanties. Shanty repertoire borrowed from the contemporary popular music enjoyed by sailors, including minstrel music, popular marches, and land-based folk songs, which were adapted to suit musical forms matching the various labor tasks required to operate a sailing ship. Such tasks, which usually required a coordinated group effort in either a pulling or pushing action, included weighing anchor and setting sail. "Poor Paddy Works on the Railway" is a popular Irish and American folk song. Historically, it was often sung as a sea chanty. The song portrays an Irish worker working on a railroad. There are numerous titles of the song including, "Pat Works on the Railway" and "Paddy on the Railway". "Paddy Works on the Erie" is another version of the song. "Paddy on the Railway" is attested as a chanty in the earliest known published work to use the word "chanty", G. E. Clark's Seven Years of a Sailor's Life (1867). Clark recounted experiences fishing on the Grand Banks of Newfoundland, in a vessel out of Provincetown, Mass. c. 1865–66. At one point, the crew is getting up the anchor in a storm, by means of a pump-style windlass. One of the chanties the men sing while performing this task is mentioned by title, "Paddy on the Railway." Shaker music The Shakers is a religious sect founded in 18th-century England upon the teachings of Ann Lee. Shakers today are most known for their cultural contributions, especially style of music and furniture. The Shakers composed thousands of songs, and also created many dances; both were an important part of the Shaker worship services. In Shaker society, a spiritual "gift" could also be a musical revelation, and they considered it important to record musical inspirations as they occurred. "Simple Gifts" was composed by Elder Joseph Brackett and originated in the Alfred Shaker community in Maine in 1848. Aaron Copland's iconic 1944 ballet score Appalachian Spring, uses the now famous Shaker tune "Simple Gifts" as the basis of its finale. Folk dancing Folk dances of British origin include the square dance, descended from the quadrille, combined with the American innovation of a caller instructing the dancers. The religious communal society known as the Shakers emigrated from England during the 18th century and developed their own folk dance style. Locations and landmarks the "Lost Colony" of Roanoke Island: In 1587, Sir Walter Raleigh recruited over 100 men, women and children to journey from England to Roanoke Island on North Carolina's coast and establish the first English settlement in America under the direction of John White as governor. Virginia Dare (born August 18, 1587) was the first child born in the Americas to English parents, Ananias and Eleanor White Dare in the short-lived Roanoke Colony. The fact of her birth is known because the governor of the settlement, Virginia Dare's grandfather, John White, returned to England in 1587 to seek fresh supplies. When White eventually returned three years later, Virginia and the other colonists were gone. During the past four hundred years, Virginia Dare has become a prominent figure in American myth and folklore, symbolizing different things to different groups of people. She is the subject of a poem (Peregrine White and Virginia Dare) by Rosemary and Stephen Vincent Benét, and the North Carolina Legend of the White Doe. While often cited as an indigenous legend, the white doe seems to have its roots in English folklore. White deer are common in English legends and often used as symbols of Christian virtue. A similar story of a young girl transformed into a white deer can be found in Yorkshire, where it formed the basis for Wordsworth's poem The White Doe of Rylstone. In the four centuries since their disappearance, the Roanoke colonists have been the subject of a mystery that still challenges historians and archaeologists as one of America's oldest. Bennington Triangle is an area of southwestern Vermont within which a number of people went missing between 1945 and 1950. The area shares characteristics with the Bridgewater Triangle in Southeastern Massachusetts. The Bridgewater Triangle is an area of about 200 square miles (520 km2) within southeastern Massachusetts in the United States, claimed to be a site of alleged paranormal phenomena, ranging from UFOs to poltergeists, orbs, balls of fire and other spectral phenomena, various bigfoot-like sightings, giant snakes and thunderbirds. The term was coined by New England based cryptozoologist Loren Coleman. Times Square is a major commercial intersection in Midtown Manhattan, New York City, at the junction of Broadway and Seventh Avenue and stretching from West 42nd to West 47th Streets. Times Square – iconified as "The Crossroads of the World" is the brightly illuminated hub of the Broadway Theater District. Formerly Longacre Square, Times Square was renamed in April 1904 after The New York Times moved its headquarters to the newly erected Times Building site of the annual ball drop on New Year's Eve. The northern triangle of Times Square is technically Duffy Square, dedicated in 1937 to Chaplain Francis P. Duffy of New York City's "Fighting 69th" Infantry Regiment; a memorial to Duffy is located there, along with a statue of George M. Cohan. The Duffy Statue and the square were listed on the National Register of Historic Places in 2001. Empire State Building is a 102-story skyscraper located in New York City at the intersection of Fifth Avenue and West 34th Street. Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for 40 years, from its completion in 1931. The Empire State Building is generally thought of as an American cultural icon. The project involved 3,400 workers, mostly immigrants from Europe, along with hundreds of Mohawk ironworkers, many from the Kahnawake reserve near Montreal. Perhaps the most famous popular culture representation of the building is in the 1933 film King Kong, in which the title character, a giant ape, climbs to the top to escape his captors but falls to his death after being attacked by airplanes. The 1957 romantic drama film An Affair to Remember involves a couple who plan to meet atop the Empire State Building, a rendezvous that is averted by an automobile accident. The 1993 film Sleepless in Seattle, a romantic comedy partially inspired by An Affair to Remember, climaxes with a scene at the Empire State observatory. Other locations and landmarks that have become part of American folklore include: Independence Hall, Monument Valley, Ellis Island, Hoover Dam, Pearl Harbor, the Vietnam War Memorial, and the Grand Canyon. Cultural icons The Liberty Bell is an iconic symbol of American independence, located in Philadelphia, Pennsylvania. The bell was commissioned from the London firm of Lester and Pack in 1752, and was cast with the lettering (part of Leviticus 25:10) "Proclaim LIBERTY throughout all the land unto all the inhabitants thereof." In the 1830s, the bell was adopted as a symbol by abolitionist societies, who dubbed it the "Liberty Bell". It acquired its distinctive large crack sometime in the early 19th century—a widespread story claims it cracked while ringing after the death of Chief Justice John Marshall in 1835. The Statue of Liberty a colossal neoclassical sculpture on Liberty Island in New York Harbor, designed by Frédéric Bartholdi and dedicated on October 28, 1886. The statue, a gift to the United States from the people of France, is of a robed female figure representing Libertas, the Roman goddess of freedom, who bears a torch and a tablet upon which is inscribed the date of the American Declaration of Independence, July 4, 1776. The statue is an icon of freedom and of the United States: a welcoming signal to immigrants arriving from abroad. Uncle Sam (initials U.S.) is a common national personification of the American government and came into use during the War of 1812. According to legend, Samuel Wilson, a meatpacker in New York, supplied rations for the soldiers and stamped the letters U.S. on the boxes, which stood for United States but was jokingly said to be the initials of Uncle Sam. An Uncle Sam is mentioned as early as 1775, in the original "Yankee Doodle" lyrics of the Revolutionary War . "Columbia", who first appeared in 1738 and sometimes was associated with liberty, is the personification of the American nation, while Uncle Sam is a personification of the government; they are some times shown working together or disputing with one another over political issues, especially in the political cartoons of Puck. With the American Revolutionary War came Brother Jonathan as a personification of the American Everyman; but it wasn't until after the War of 1812 Uncle Sam appeared. Brother Jonathan saw full literary development into the personification of American national character through the 1825 novel Brother Jonathan by John Neal. Shark Mouth nose art on military aircraft: Although originally from Austria this stylistic design was applied to the American Volunteer Group in Asia known more commonly as "The Flying Tigers". This design was painted on the units' P-40 fighters around the large air intake near the front of the plane. This image has since been placed on various aircraft such as American UH-1 and AH-1 helicopters during the Vietnam War as well as the modern-day A-10 Thunderbolt II, A-29 Supertucano and AT-6 Wolverine, and other vehicles both military and civilian alike. Other cultural icons include Rosie the Riveter, the United States Constitution, the Colt Single Action Army, Smokey Bear, the Boeing B-52 Stratofortress, and apple pie. History Historical events that form a part of American folklore include: the Boston Massacre, the Boston Tea Party, Paul Revere's Ride, the Battle of the Alamo, the Salem witch trials, the Gunfight at the O.K. Corral, the California Gold Rush, the Battle of the Little Bighorn, the Battle of Gettysburg, the Attack on Pearl Harbor, and the September 11th attacks. See also Black Heritage Trail John C.

Sid Meier's Alpha Centauri is a 4X video game, considered a spiritual sequel to the Civilization series. Set in a science fiction depiction of the 22nd century, the game begins as seven competing ideological factions land on the planet Chiron ("Planet") in the Alpha Centauri star system. As the game progresses, Planet's growing sentience becomes a formidable obstacle to the human colonists. Sid Meier, designer of Civilization, and Brian Reynolds, designer of Civilization II, developed Alpha Centauri after they left MicroProse to join with Jeff Briggs in creating a new video game developer: Firaxis Games. Electronic Arts released both Alpha Centauri and its expansion, Sid Meier's Alien Crossfire, in 1999. The following year, Aspyr Media ported both titles to Classic Mac OS while Loki Software ported them to Linux. Alpha Centauri features improvements on Civilization IIs game engine, including simultaneous multiplay, social engineering, climate, customizable units, alien native life, additional diplomatic and spy options, additional ways to win, and greater mod-ability. Alien Crossfire introduces five new human and two non-human factions, as well as additional technologies, facilities, secret projects, native life, unit abilities, and a victory condition. The game received wide critical acclaim, being compared favorably to Civilization II. Critics praised its science fiction storyline (comparing the plot to works by Stanley Kubrick, Frank Herbert, Arthur C. Clarke, and Isaac Asimov), the in-game writing, the voice acting, the user-created custom units, and the depth of the technology tree. Alpha Centauri also won several awards for best game of the year and best strategy game of the year. Synopsis Setting Space-race victories in the Civilization series conclude with a journey to Alpha Centauri. Beginning with that premise the Alpha Centauri narrative starts in the 22nd century, after the United Nations sends "Unity", a colonization mission, to Alpha Centauri's planet Chiron ("Planet"). Unbeknownst to humans, advanced extraterrestrials ("Progenitors") had been conducting experiments in vast distributed nervous systems, culminating in a planetary biosphere-sized presentient nervous system ("Manifold") on Chiron, leaving behind monoliths and artifacts on Planet to guide and examine the system's growth. Immediately prior to the start of the game, a reactor malfunction on the Unity spacecraft wakes the crew and colonists early and irreparably severs communications with Earth. After the captain is assassinated, the most powerful leaders on board build ideological factions with dedicated followers, conflicting agendas for the future of mankind, and "desperately serious" commitments. As the ship breaks up, seven escape pods, each containing a faction, are scattered across Planet. In the Alien Crossfire expansion pack, players learn that alien experiments led to disastrous consequences at Tau Ceti, creating a hundred-million-year evolutionary cycle that ended with the eradication of most complex animal life in several neighboring inhabited star systems. After the disaster (referred to by Progenitors as "Tau Ceti Flowering"), the Progenitors split into two factions: Manifold Caretakers, opposed to further experimentation and dedicated to preventing another Flowering; and Manifold Usurpers, favoring further experimentation and intending to induce a controlled Flowering in Alpha Centauris Planet. In Alien Crossfire, these factions compete along with the human factions for control over the destiny of Planet. Characters and factions The game focuses on the leaders of seven factions, chosen by the player from the 14 possible leaders in Alpha Centauri and Alien Crossfire, and Planet (voiced by Alena Kanka). The characters are developed from the faction leaders' portraits, the spoken monologues accompanying scientific discoveries and the "photographs in the corner of a commlink – home towns, first steps, first loves, family, graduation, spacewalk." The leaders in Alpha Centauri comprise: Lady Deirdre Skye, a Scottish activist (voiced by Carolyn Dahl), of Gaia's Stepdaughters; Chairman Sheng-Ji Yang, a Chinese Legalist official (voiced by Lu Yu), of the Human Hive; Academician Prokhor Zakharov, a Russian academic (voiced by Yuri Nesteroff) of the University of Planet; CEO Nwabudike Morgan, a Namibian businessman (voiced by Regi Davis), of Morgan Industries; Colonel Corazon Santiago, an American militiawoman (voiced by Wanda Niño) of the Spartan Federation; Sister Miriam Godwinson, an American minister and social psychologist (voiced by Gretchen Weigel), of the Lord's Believers; and Commissioner Pravin Lal, an Indian surgeon and diplomat (voiced by Hesh Gordon), of the Peacekeeping Forces. The player controls one of the leaders and competes against the others to colonize and conquer Planet. The Datalinks (voiced by Robert Levy and Katherine Ferguson) are minor characters who provide information to the player. Each faction excels at one or two important aspects of the game and follows a distinct philosophical belief, such as technological utopianism, Conclave Christianity, "free-market" capitalism, militarist survivalism, Chinese Legalism, U.N. Charter humanitarianism, or Environmentalist Gaia philosophy. The game takes place on Planet, with its "rolling red ochre plains" and "bands of lonely terraformed green". The seven additional faction leaders in Alien Crossfire are Prime Function Aki Zeta-Five, a Norwegian research assistant-turned-cyborg (voiced by Allie Rivenbark), of The Cybernetic Consciousness; Captain Ulrik Svensgaard, an American fisherman and naval officer (voiced by James Liebman), of The Nautilus Pirates; Foreman Domai, an Australian labor leader (voiced by Frederick Serafin), of The Free Drones; Datajack Sinder Roze, a Trinidadian hacker (voiced by Christine Melton), of The Data Angels; Prophet Cha Dawn, a human born on Planet (voiced by Stacy Spenser) of The Cult of Planet; Guardian Lular H'minee, a Progenitor leader (voiced by Jeff Gordon), of The Manifold Caretakers; and Conqueror Judaa Maar, a Progenitor leader (voiced by Jeff Gordon), of The Manifold Usurpers. Plot The story unfolds via the introduction video, explanations of new technologies, videos obtained for completing secret projects, interludes, and cut-scenes. The native life consists primarily of simple wormlike alien parasites and a type of red fungus that spreads rapidly via spores. The fungus is difficult to traverse, provides invisibility for the enemy, provides few resources, and spawns "mindworms" that attack population centres and military units by neurally parasitising them. Mindworms can eventually be captured and bred in captivity and used as terroristic bioweapons, and the player eventually discovers that the fungus and mindworms can think collectively. A voice intrudes into the player's dreams and soon waking moments, threatening more attacks if the industrial pollution and terraforming by the colonists is not reversed. The player discovers that Planet is a dormant semi-sentient hive organism that will soon experience a metamorphosis which will destroy all human life. To counter this threat, the player or a computer faction builds "The Voice of Alpha Centauri" secret project, which artificially links Planet's distributed nervous system into the human Datalinks, delaying Planet's metamorphosis into full self-awareness but incidentally increasing its ultimate intelligence substantially by giving it access to all of humanity's accumulated knowledge. Finally, the player or a computer faction embraces the "Ascent to Transcendence" in which humans too join their brains with the hive organism in its metamorphosis to godhood. Thus, Alpha Centauri closes "with a swell of hope and wonder in place of the expected triumphalism", reassuring "that the events of the game weren't the entirety of mankind's future, but just another step." Gameplay Alpha Centauri, a turn-based strategy game with a science fiction setting, is played from an isometric perspective. Many game features from Civilization II are present, but renamed or slightly tweaked: players establish bases (Civilization II's cities), build facilities (buildings) and secret projects (Wonders of the World), explore territory, research technology, and conquer other factions (civilizations). In addition to conquering all non-allied factions, players may also win by obtaining votes from three quarters of the total population (similar to Civilization IVs Diplomatic victory), "cornering the Global Energy Market", completing the Ascent to Transcendence secret project, or for alien factions, constructing six Subspace Generators. The main map (the upper two thirds of the screen) is divided into squares, on which players can establish bases, move units and engage in combat. Through terraforming, players may modify the effects of the individual map squares on movement, combat and resources. Resources are used to feed the population, construct units and facilities, and supply energy. Players can allocate energy between research into new technology and energy reserves. Unlike Civilization II, new technology grants access to additional unit components rather than pre-designed units, allowing players to design and re-design units as their factions' priorities shift. Energy reserves allow the player to upgrade units, maintain facilities, and attempt to win by the Global Energy Market scenario. Bases are military strongpoints and objectives that are vital for all winning strategies. They produce military units, house the population, collect energy, and build secret projects and Subspace Generators. Facilities and secret projects improve the performance of individual bases and of the entire faction. In addition to terraforming, optimizing individual base performance and building secret projects, players may also benefit their factions through social engineering, probe teams, and diplomacy. Social engineering modifies the ideologically based bonuses and penalties forced by the player's choice of faction. Probe teams can sabotage and steal information, units, technology, and energy from enemy bases, while diplomacy lets the player create coalitions with other factions. It also allows the trade or transfer of units, bases, technology and energy. The Planetary Council, similar to the United Nations Security Council, takes Planet-wide actions and determines population victories. In addition to futuristic technological advances and secret projects, the game includes alien life, structures and machines. "Xenofungus" and "sea fungus" provide movement, combat, and resource penalties, as well as concealment for "mind worms" and "spore launchers". Immobile "fungal towers" spawn native life. Native life, including the seaborne "Isles of the Deep" and "Sealurks" and airborne "Locusts of Chiron", use psionic combat, an alternate form of combat which ignores weapons and armor. Monoliths repair units and provide resources; artifacts yield new technology and hasten secret projects; landmarks provide resource bonuses; and random events add danger and opportunity. Excessive development leads to terraforming-destroying fungus blooms and new native life. Alpha Centauri provides a single player mode and supports customization and multiplayer. Players may customize the game by choosing options at the beginning of the game, using the built-in scenario and map editors, and modifying Alpha Centauris game files. In addition to a choice of seven (or 14 in Alien Crossfire) factions, pre-game options include scenario game, customized random map, difficulty level, and game rules that include victory conditions, research control, and initial map knowledge. The scenario and map editors allow players to create customized scenarios and maps. The game's basic rules, diplomatic dialog, and the factions' starting abilities are in text files, which "the designers have done their best to make it reasonably easy to modify..., even for non-programmers." Alpha Centauri supports play by email ("PBEM") and TCP/IP mode featuring simultaneous movement, and introduces direct player-to-player negotiation, allowing the unconstrained trade of technology, energy, maps, and other elements. Development Inspirations In 1996, MicroProse released the lauded Civilization II, designed by Brian Reynolds. Spectrum Holobyte who owned MicroProse at the time, opted to consolidate their business under the MicroProse name, moving the company from Maryland to California by the time the game shipped, and laying off several MicroProse employees. Disagreements between the new management and its employees prompted Reynolds, Jeff Briggs, and Sid Meier (designer of the original Civilization) to leave MicroProse and found Firaxis. Although unable to use the same intellectual property as Civilization II, the new company felt that players wanted "a new sweeping epic of a turn-based game". Having just completed a game of human history up to the present, they wanted a fresh topic and chose science fiction. With no previous experience in science fiction games, the developers believed future history was a fitting first foray. For the elements of exploring and terraforming an alien world, they chose a plausible near future situation of a human mission to colonize the solar system's nearest neighbour and human factions. Reynolds researched science fiction for the game's writing. His inspiration included "classic works of science fiction", including Frank Herbert's The Jesus Incident and Hellstrom's Hive, A Fire Upon the Deep by Vernor Vinge, and The Mote in God's Eye by Larry Niven and Jerry Pournelle for alien races; Kim Stanley Robinson's Red Mars, Slant by Greg Bear, and Stephen R. Donaldson's The Real Story for future technology and science; and Dune by Herbert and Bear's Anvil of Stars for negative interactions between humans. Alpha Centauri set out to capture the whole sweep of humanity's future, including technology, futuristic warfare, social and economic development, the future of the human condition, spirituality, and philosophy. Reynolds also said that "getting philosophy into the game" was one of the attractions of the game. Believing good science fiction thrives on constraint, the developers began with near-future technologies. As they proceeded into the future, they tried to present a coherent, logical, and detailed picture of future developments in physics, biology, information technology, economics, society, government, and philosophy. Alien ecologies and mysterious intelligences were incorporated into Alpha Centauri as external "natural forces" intended to serve as flywheels for the backstory and a catalyst for many player intelligences. Chris Pine, creator of the in-game map of Planet, strove to make Planet look like a real planet, which resulted in evidence of tectonic action. Another concern was that Planet matched the story, which resulted in the fungus being connected across continents, as it is supposed to be a gigantic neural network. Terraforming is a natural outgrowth of colonizing an alien world. The first playable prototype was just a map generator that tested climate changes during the game. This required the designers to create a world builder program and climatic model far more powerful than anything they'd done before. Temperature, wind, and rainfall patterns were modeled in ways that allow players to make changes: for example, creating a ridge-line and then watching the effects. In addition to raising terrain, the player can also divert rivers, dig huge boreholes into the planet's mantle, and melt ice caps. In addition to scientific advances, the designers speculated on the future development of human society. The designers allow the player to decide on a whole series of value choices and choose a "ruthless", "moderate", or "idealistic" stance. Reynolds said the designers don't promote a single "right" answer, instead giving each value choice positive and negative consequences. This design was intended to force the player to "think" and make the game "addictive". He also commented that Alpha Centauris fictional nature allowed them to draw their characters "a lot more sharply and distinctly than the natural blurring and greyness of history". Chiron, the name of the planet, is the name of the only non-barbaric centaur in Greek mythology and an important loregiver and teacher for humanity. The name also pays homage to James P. Hogan's 1982 space opera novel Voyage from Yesteryear, in which a human colony is artificially planted by an automatic probe on a planet later named by colonists as Chiron. In the game, Chiron has two moons, named after the centaurs Nessus and Pholus, with the combined tidal force of Earth's Moon, and is the second planet out from Alpha Centauri A, the innermost planet being the Mercury-like planet named after the centaur Eurytion. Alpha Centauri B is also dubbed Hercules, a reference to him killing several centaurs in mythology, and the second star preventing the formation of larger planets. The arrival on Chiron is referred to as "Planetfall", which is a term used in many science fiction novels, including Robert A. Heinlein's Future History series, and Infocom's celebrated comic interactive fiction adventure Planetfall. Vernor Vinge's concept of technological singularity is the origin of the Transcendence concept. The game's cutscenes use montages of live-action video, CGI, or both; most of the former is from the 1992 experimental documentary Baraka. Alpha Centauri In July 1996, Firaxis began work on Alpha Centauri, with Reynolds heading the project. Meier and Reynolds wrote playable prototype code and Jason Coleman wrote the first lines of the development libraries. Because the development of Gettysburg took up most of Firaxis' time, the designers spent the first year prototyping the basic ideas. By late 1996, the developers were playing games on the prototype, and by the middle of the next year, they were working on a multiplayer engine. Although Firaxis intended to include multiplayer support in its games, an important goal was to create games with depth and longevity in single-player mode because they believed that the majority of players spend most of their time playing this way. Reynolds felt that smart computer opponents are an integral part of a classic computer game, and considered it a challenge to make them so. Reynolds' previous games omitted internet support because he believed that complex turn-based games with many player options and opportunities for player input are difficult to facilitate online. Reynolds said that the most important principle of game design is for the designer to play the game as it is developed; Reynolds claimed that this was how a good artificial intelligence (AI) was built. To this end, he would track the decisions he made and why he made them as he played the game. The designer also watched what the computer players did, noting "dumb" actions and trying to discover why the computer made them. Reynolds then taught the computer his reasoning process so the AI could find the right choice when presented several attractive possibilities. He said the AI for diplomatic personalities was the best he had done up to that point. Doug Kaufman, a co-designer of Civilization II, was invited to join development as a game balancer. Reynolds cited the Alpha Centauris balance for the greater sense of urgency and the more pressing pacing than in his earlier game, Sid Meier's Colonization. According to producer Timothy Train, in designing the strengths and weaknesses of the factions, the goal was to suggest, without requiring, certain strategies and give the player interesting and fun things to do without unbalancing the game. He didn't want a faction to be dependent on its strength or a faction's power to be dominant over the rest. Train felt that fun meant the factions always have something fun to do with their attributes. Around the summer of 1997, the staff began research on the scientific realities involved in interstellar travel. In late 1997, Bing Gordon—then Chief Creative Officer of Electronic Arts—joined the team, and was responsible for the Planetary Council, extensive diplomacy, and landmarks. A few months before the 1998 Electronic Entertainment Expo (E3), the team incorporated the Explore/Discover/Build/Conquer marketing campaign into the game. The game was announced in May 1998 at E3. In the latter half of 1998, the team produced a polished and integrated interface, wrote the game manual and foreign language translations, painted the faction leader portraits and terrain, built the 3D vehicles and vehicle parts, and created the music. Michael Ely directed the Secret Project movies and cast the faction leaders. 25 volunteers participated in Firaxis' first public beta test. The beta testers suggested the Diplomatic and Economic victories and the Random Events. The design team started with a very simple playable game. They strengthened the "fun" aspects and fixed or removed the unenjoyable ones, a process Sid Meier called "surrounding the fun". After the revision, they played it again, repeating the cycle of revision and play. Playing the game repeatedly and in-depth was a rule at Firaxis. In the single-player mode, the team tried extreme strategies to find any sure-fire paths to victory and to see how often a particular computer faction ends up at the bottom. The goal was a product of unprecedented depth, scope, longevity, and addictiveness, where the player is always challenged by the game to come up with new strategies with no all-powerful factions or unstoppable tactics. According to Reynolds, the process has been around since Sid Meier's early days at Microprose. At Firaxis, as iterations continue, they expand the group giving feedback, bringing in outside gamers with fresh perspectives. Alpha Centauri was the first Firaxis game with public beta testers. Finally, Brian Reynolds discussed the use of the demo in the development process. Originally a marketing tool released prior to the game, they started getting feedback. They were able to incorporate many suggestions into the retail version. According to Brian Reynolds, they made improvement in the game's interface, added a couple of new features and fixed a few glitches. They also improved some rules, fine-tuned the game balance and improved the AI. Finally, he adds that they continued to add patches to enhance the game after the game was released. In the months leading to the release of Alpha Centauri, multimedia producer Michael Ely wrote the 35 weekly episodes of Journey to Centauri detailing the splintering of the U.N. mission to Alpha Centauri. Alien Crossfire A month after Alpha Centauris February 1999 release, the Firaxis team began work on the expansion pack, Sid Meier's Alien Crossfire. Alien Crossfire features seven new factions (two that are non-human), new technologies, new facilities, new secret projects, new alien life forms, new unit special abilities, new victory conditions (including the new "Progenitor Victory") and several additional concepts and strategies. The development team included Train as producer and designer, Chris Pine as programmer, Jerome Atherholt and Greg Foertsch as artists, and Doug Kaufman as co-designer and game balancer. The team considered several ideas, including a return to a post-apocalyptic earth and the conquest of another planet in the Alpha Centauri system, before deciding to keep the new title on Planet. The premise allowed them to mix and match old and new characters and delve into the mysteries of the monoliths and alien artifacts. The backstory evolved quickly, and the main conflict centered on the return of the original alien inhabitants. The idea of humans inadvertently caught up in an off-world civil war focused the story. Train wanted to improve the "build" aspects, feeling that the god-game genre had always been heavily slanted towards the "Conquer" end of the spectrum. He wanted to provide "builders" with the tools to construct an empire in the face of heated competition. The internet community provided "invaluable" feedback. The first "call for features" was posted around April 1999 and produced the Fletchette Defense System, Algorithmic Enhancement, and The Nethack Terminus. The team had several goals: factions should not be "locked-in" to certain strategies; players should have interesting things to do without unbalancing the game, and the factions must be fun to play. The team believed the "coolness" of the Progenitor aliens would determine the success or failure of Alien Crossfire. They strove to make them feel significantly different to play, but still compatible with the existing game mechanics. The developers eventually provided the aliens with Battle Ogres, a Planetary survey, non-blind research, and other powers to produce "a nasty and potent race that would take the combined might of humanity to bring them down". Chris Pine modified the AI to account for the additions. The team also used artwork, sound effects, music, and diplomatic text to set the aliens apart. Other than the aliens, the Pirates proved to be the toughest faction to balance because their ocean start gave them huge advantages. Upon completion, the team felt that Alien Crossfire was somewhere between an expansion and a full-blown sequel. In the months leading to the release of Alien Crossfire, multimedia producer Michael Ely wrote the 9 episodes of Centauri: Arrival, introducing the Alien Crossfire factions. The game initially had a single production run. Electronic Arts bundled Alpha Centauri and Alien Crossfire in the Alpha Centauri Planetary Pack in 2000 and included both games in The Laptop Collection in 2003. In 2000, both Alpha Centauri and Alien Crossfire were ported to Classic Mac OS by Aspyr Media and to Linux by Loki Software. Reception Alpha Centauri received wide critical acclaim upon its release, with reviewers voicing respect for the game's pedigree, especially that of Reynolds and Meier. The video game review aggregator websites GameRankings and Metacritic, which collect data from numerous review websites, listed scores of 92% and 89%, respectively. The game was favorably compared to Reynold's previous title, Civilization II, and Rawn Shah of IT World Canada praised the expansion for a "believable" plot. However, despite its critical reception, it sold the fewest copies of all the games in the Civilization series. It sold more than 100,000 copies in its first two months of release. This was followed by 50,000 copies in April, May and June. In the United States, Alpha Centauri was the tenth-best-selling computer game of 1999's first half. Its sales in that country alone reached 224,939 copies by the end of 1999, and rose to 281,115 units by September 2000. Critical reaction The game showed well at the 1998 Electronic Entertainment Expo (E3). Walter Morbeck of GameSpot said that Alpha Centauri was "more than hi-tech physics and new ways to blow each other up", and that the game would feature realistic aliens. Terry Coleman of Computer Gaming World predicted that Alpha Centauri would be "another huge hit". OGR awarded it "Most Promising Strategy Game" and one of the top 25 games of E3 '98. In a vote of 27 journalists from 22 gaming magazine, Alpha Centauri won "Best Turn Based Strategy" of E3 Show Award. Aaron John Loeb, the Awards Committee Chairman, said "for those that understand the intricacies, the wonder, the glory of turn based 'culture building,' this is the game worth skipping class for." Alpha Centauri's science fiction storyline received high praise; IGN considered the game an exception to PC sci-fi cliches, and GamePro compared the plot to the works of writers Stanley Kubrick and Isaac Asimov. J.C. Herz of The New York Times suggested that the game was a marriage of SimCity and Frank Herbert's Dune. GamePros Dan Morris said "As the single-player campaign builds to its final showdown, the ramifications of the final theoretical discoveries elevate Alpha Centauri from great strategy game to science-fiction epic." Game Revolution said, "The well crafted story, admirable science-fiction world, fully realized scenario, and quality core gameplay are sure to please." Edge praised the uniqueness of expression saying it was "the same kind of old-fashioned, consensual storytelling that once drew universes out of ASCII." The in-game writing and faction leaders were also well-received for their believability, especially the voice acting. GameSpot reviewer Denny Atkin called the factions and their abilities Alpha Centauris "most impressive aspect". Greg Tito of The Escapist said, "the genius of the game is how it flawlessly blends its great writing with strategy elements." Alpha Centauri's turn-based gameplay, including the technology trees and factional warfare, was commonly compared to Civilization and Civilization II. The Adrenaline Vault's Pete Hines said, "While Alpha Centauri is the evolutionary off-spring to [Civilization] and [Civilization II], it is not [Civilization II] in space. Although the comparison is inevitable because of the lineage, it is still short-sighted." Edge in 2006 praised "Alpha Centauri's greater sophistications as a strategy game." IGN said "Alpha Centauri is a better game than Civilization II; it's deep, rich, rewarding, thought-provoking in almost every way." Game Revolution's reviewer was less magnanimous, saying "Alpha Centauri is at least as good a game as Civilization 2. But it is its great similarity that also does it the most detriment. Alpha Centauri simply does not do enough that is new; it just doesn't innovate enough to earn a higher grade." The ability to create custom units was praised, as was the depth of the tech tree. The artificial intelligence of computer-controlled factions, which featured adaptability and behavioral subtlety, was given mixed comments; some reviewers thought it was efficient and logical, while others found it confusing or erratic. Edge was disappointed in the game's diplomacy, finding "no more and no less than is expected from the genre" and unhappy with "the inability to sound out any real sense of relationship or rational discourse." The game's graphics were widely acknowledged to be above average at the time of its release, but not revolutionary. Its maps and interface were considered detailed and in accordance with a space theme, but the game was released with a limited color palette. The in-game cutscenes, particularly the full motion video that accompanied technological advances, were praised for their quality and innovation. Alpha Centauri's sound and music received similar comments; FiringSquad said "[The sound effect quality] sort of follows the same line as the unit graphics – not too splashy but enough to get the job done." Next Generation reviewed the PC version of the game, rating it five stars out of five, and stated that "Sid Meier creates yet another masterpiece in this game that, at a glance, looks all too familiar." Alpha Centauri has won several Game of the Year awards, including those from the Denver Post and the Toronto Sun. It won the "Turn-based Strategy Game of the Year" award from GameSpot as well. The Academy of Interactive Arts & Sciences awarded Alpha Centauri for "PC Strategy Game of the Year" at the 2nd Annual Interactive Achievement Awards; it also received nominations for "Game of the Year", "Computer Entertainment Title of the Year", and "Outstanding Achievement in Interactive Design". In 2000, Alpha Centauri won the Origins Award for Best Strategy Computer Game of 1999. The editors of PC Gamer US named Alpha Centauri their "Best Turn-Based Strategy Game" of 1999, and wrote that it "set a new standard for this venerable genre." Alpha Centauri has the distinction of receiving gaming magazine PC Gamers highest score to date as of 2019 (98%), alongside Half-Life 2 and Crysis, surpassing Civilization IIs score (97%). Alien Crossfire was a runner-up for Computer Games Strategy Pluss 1999 "Add-on of the Year" award, which ultimately went to Heroes of Might and Magic III: Armageddon's Blade. Legacy There have been no direct sequels beyond Alien Crossfire, something that writer Greg Tito attributed to Reynolds leaving Firaxis in 2000 to form Big Huge Games. Alien Crossfire producer and lead designer Timothy Train also left Firaxis with Reynolds. However, a spiritual sequel, Civilization: Beyond Earth, was announced by Firaxis in April 2014 and released on October 24, 2014; several of those that worked on Alpha Centauri helped to develop the new title. A review in Polygon noted however that while the new game has better graphics, its story fails to rival the original, a sentiment echoed by another review in PC Gamer. Another in Engadget noted "as a spiritual successor to Sid Meier's Alpha Centauri, however, it's a cut-rate disappointment". Many of the features introduced in Alpha Centauri were carried over into subsequent Civilization titles; upon its release, Civilization III was compared negatively to Alpha Centauri, whose Civilization characteristics were reminiscent of faction bonuses and penalties. The government system in Civilization IV closely resembles Alpha Centauris, and Civilization V includes a new victory condition: the completion of the 'Utopia project', which is reminiscent of the Ascent to Transcendence secret project. According to Edge magazine, Alpha Centauri remained "highly regarded" in 2006. A decade after its release, Sold-Out Software and GOG.com re-released the game for online-download sales. Escapist Magazine reviewed the game in 2014, noting that "Alpha Centauri is still playable. It still has a unique flavor that is unlike anything else". After the release of the expansion, multimedia producer Michael Ely wrote a trilogy of novels based on the game. Writer Steve Darnall and illustrator Rafael Kayanan also made a graphic novel entitled Alpha Centauri: Power of the Mindworms. Steve Jackson Games published GURPS Alpha Centauri, a sourcebook for the GURPS role-playing game set in the Alpha Centauri universe.

Abu Sayyaf (; ; , ASG), officially known by the Islamic State as the Islamic State – East Asia Province, is a Jihadist militant and pirate group that follows the Wahhabi doctrine of Sunni Islam. It is based in and around Jolo and Basilan islands in the southwestern part of the Philippines, where for more than four decades, Moro groups have been engaged in an insurgency seeking to make Moro Province independent. The group is considered violent and was responsible for the Philippines' worst terrorist attack, the bombing of MV Superferry 14 in 2004, which killed 116 people. The name of the group is derived from the Arabic (; "father of"), and (; "swordsmith"). , the group is estimated to have about 20 members, down from 1,250 in 2000. They use mostly improvised explosive devices, mortars and automatic rifles. Since its inception in 1989, the group has carried out bombings, kidnappings, assassinations and extortion. They have been involved in criminal activities, including rape, child sexual assault, forced marriage, drive-by shootings and drug trafficking. The goals of the group "appear to have alternated over time between criminal objectives and a more ideological intent". The group has been designated as a terrorist group by Australia, Canada, Indonesia, Japan, Malaysia, the Philippines, the United Arab Emirates, the United Kingdom and the United States. From January 15, 2002, to February 24, 2015, fighting Abu Sayyaf became a mission of the American military's Operation Enduring Freedom and part of the Global War on Terrorism. Several hundred United States soldiers were stationed in the area to mainly train local forces in counter-terror and counterguerrilla operations, but, following a status of forces agreement and under Philippine law, they were not allowed to engage in direct combat. The group was founded by Abdurajak Abubakar Janjalani, and led after his death in 1998 by his younger brother Khadaffy Janjalani until his death in 2006. On July 23, 2014, Isnilon Hapilon, one of the group's leaders, swore an oath of loyalty to Abu Bakr al-Baghdadi, the leader of the Islamic State (IS). In September 2014, the group began kidnapping people for ransom, in the name of the IS. Background and history In the early 1970s, the Moro National Liberation Front (MNLF) was the main Muslim rebel group fighting in Basilan and Mindanao. Abdurajak Abubakar Janjalani, the older brother of Khadaffy Janjalani, had been a teacher from Basilan, who studied Islamic theology and Arabic in Libya, Syria and Saudi Arabia during the 1980s. Abdurajak went to Afghanistan to fight against the Soviet Union and the Afghan government during the Soviet–Afghan War. During that period, he was alleged to have met Osama bin Laden and been given $6 million to establish a more Islamic group drawn from the MNLF. Both Abdurajak Abubakar and Khadaffy were natives of Isabela City, one of the poorest cities of the Philippines and capital of Basilan. Abdurajak Abubakar Janjalani leadership (1989–1998) In the early 1990s, the MNLF moderated into governing the Autonomous Region in Muslim Mindanao, becoming the ruling government in majority Muslim areas of Mindanao in 1996. When Abdurajak returned to Basilan in 1990, he gathered radical members of the old MNLF who wanted to resume armed struggle and in 1991 established the Abu Sayyaf. Janjalani was funded by a Saudi Islamist, Mohammed Jamal Khalifa, who came to the Philippines in 1987 or 1988 and was head of the Philippine branch of the International Islamic Relief Organization foundation. A defector from Abu Sayyaf told Filipino authorities, "The IIRO was behind the construction of Mosques, school buildings, and other livelihood projects" but only "in areas penetrated, highly influenced and controlled by the Abu Sayyaf". According to the defector, "Only 10 to 30% of the foreign funding goes to the legitimate relief and livelihood projects and the rest go to terrorist operations". Khalifa married a local woman, Alice "Jameelah" Yabo. By 1995, Abu Sayyaf was active in large-scale bombings and attacks. The first attack was the assault on the town of Ipil, Zamboanga del Sur in April 1995. This year marked the escape of 20-year-old Khadaffy Janjalani from Camp Crame in Manila along with another member named Jovenal Bruno. On December 18, 1998, Abdurajak was killed in a gun battle with the Philippine National Police in Basilan. He was thought to have been about 39. The death of Aburajak marked a turning point in Abu Sayyaf operations. The group shifted to kidnappings, murders, and robberies, under his younger brother Khadaffy. The Sulu Archipelago experienced some of the fiercest fights between government troops and Abu Sayyaf through the early 1990s. It was reported that Abu Sayyaf began expanding into neighboring Malaysia and Indonesia by that time. Khadaffy Janjalani leadership (1999–2007) Until his death in a gun battle on September 4, 2006, Khaddafy Janjalani was considered the nominal leader of the group by the Armed Forces of the Philippines. Then 23-year-old Khadaffy took leadership of one of the Abu Sayyaf's factions in an internecine struggle. He then worked to consolidate his leadership, causing the group to appear inactive for a period. After his leadership was secured, Abu Sayyaf began a new strategy, taking hostages. The group's motive for kidnapping became more financial than religious during this period, according to locals. Hostage money probably provides the group's financing. Abu Sayyaf expanded its operations to Malaysia in 2000, when it abducted foreigners from two resorts. This action was condemned by most Islamic leaders. It was responsible for the kidnapping and murder of more than 30 foreigners and Christian clerics and workers, including Martin and Gracia Burnham. An influential commander named Abu Sabaya was killed at sea in June 2002 while trying to evade local forces. His death was considered a crucial turning point for the group, as the number of operatives working for Abu Sayyaf sharply decreased from 1,100 in 2001 to 450 in late 2002, and had since been stagnant for the next ten years. Ghalib Andang, alias Commander Robot, one of the group's leaders, was captured in Sulu in December 2003. On 14 March 2005, inmates from the Abu Sayyaf Group rioted inside Camp Bagong Diwa in Taguig in an apparent escape attempt and barricaded the second floor of the building, leading to a standoff which ended the next day when government forces stormed the prison. 24 Abu Sayyaf members, including Commanders Robot, Kosovo (Alhamser Limbong) and Global (Nadjmi Sabdullah), were killed, along with three prison guards and a police officer. An explosion at a military base in Jolo, on February 18, 2006, was blamed on the group by Brig. General Alexander Aleo. Khadaffy was indicted in the United States District Court for the District of Columbia for his alleged involvement in terrorist attacks, including hostage-taking and murder, against United States nationals and other foreign nationals. Consequently, on February 24, 2006, Khadaffy was among six fugitives in the second and most recent group of indicted fugitives to be added to the FBI Most Wanted Terrorists list along with two fellow members, Isnilon Totoni Hapilon and Jainal Antel Sali Jr. On December 13, 2006, it was reported that Abu Sayyaf members may have been planning attacks during the Association of Southeast Asian Nations (ASEAN) summit in the Philippines. The group was reported to have trained alongside Jemaah Islamiyah militants. The plot was reported to have involved detonating a car bomb in Cebu City where the summit was to take place. On December 27, the Philippine military reported that Khaddafi's remains had been recovered near Patikul, in Jolo and that DNA tests had been ordered to confirm the discovery. He was allegedly shot in the neck in an encounter with government troops in September on Luba Hills in Patikul, Sulu. 2010–present In a video published in the summer of 2014, senior Abu Sayyaf leader Isnilon Hapilon and other masked men swore their allegiance or "bay'ah" to Abu Bakr al-Baghdadi, the "Islamic State" (IS) caliph. "We pledge to obey him on anything which our hearts desire or not and to value him more than anyone else. We will not take any emir (leader) other than him unless we see in him any obvious act of disbelief that could be questioned by Allah in the hereafter." For many years prior to this, Islamic State's competitor, al-Qaeda, had the support of Abu Sayyaf "through various connections". Observers were skeptical about whether the pledge would lead to Abu Sayyaf becoming an ISIS outpost in Southeast Asia, or was simply a way for the group to take advantage of the newer group's international publicity. In May 2017, Hapilon and other members of Abu Sayyaf joined the Islamic extremist Maute Group based in Lanao del Sur during their attempt to seize control of Marawi City and establish an IS caliphate in Mindanao, sparking the Battle of Marawi which destroyed much of the city and ended with his killing, along with that of Maute leader Omar Maute by government forces in October. In August 2020, MNLF chairman Nur Misuari turned in Abu Sayyaf sub-commander Anduljihad "Idang" Susukan to the Philippine National Police four months after Susukan surrendered to Misuari in Davao City. By 2022, the Islamic State's East Asia Province had absorbed pro-IS groups in Indonesia and a few militants in Thailand. In the latter country, alleged IS members have become involved in the South Thailand insurgency, claiming their first attack in Pattani on April 15, 2022. In 2023, the government declared that Sulu province was free of Abu Sayyaf militants. Supporters and funding Abdurajak Abubakar Janjalani's first recruits were soldiers of MNLF and the Moro Islamic Liberation Front (MILF). However, both MNLF and MILF deny links with Abu Sayyaf. Both officially distance themselves because of its attacks on civilians and its supposed profiteering. The Philippine military, however, has claimed that elements of both groups provide support to Abu Sayyaf. The group was originally not thought to receive funding from outside sources, but intelligence reports from the United States, Indonesia and Australia found intermittent ties to the Indonesian Jemaah Islamiyah terrorist group, and the Philippine government considers the Abu Sayyaf to be part of Jemaah Islamiyah. The government noted that initial funding for ASG came from al-Qaeda through the brother-in-law of Osama bin Laden, Mohammed Jamal Khalifa. Al-Qaeda-affiliated terrorist Ramzi Yousef operated in the Philippines in the mid-1990s and trained Abu Sayyaf soldiers. The 2002 edition of the United States Department's Patterns of Global Terrorism mention links to Al-Qaeda. Continuing ties to Islamist groups in the Middle East indicate that al-Qaeda may be continuing support. As of mid-2005, Jemaah Islamiyah personnel reportedly had trained about 60 Abu Sayyaf cadres in bomb assembling and detonations. Funding The group obtains most of its financing through kidnap ransom and extortion. One report estimated its revenues from ransom payments in 2000 were between $10 and $25 million. According to the State Department, it may receive funding from radical Islamic benefactors in the Middle East and South Asia. It was reported that Libya facilitated ransom payments to Abu Sayyaf. It was also suggested that Libyan money could possibly be channeled to Abu Sayyaf. Russian intelligence agencies connected with Victor Bout's planes reportedly provided Abu Sayyaf with arms. In 2014 and since, kidnapping for ransom has been the primary means of funding. The chart below collects events that Abu Sayyaf received ransoms or payments that are euphemistically called "board and lodgings". The more detailed information can be seen in the Timeline of Abu Sayyaf attacks. Motivation, beliefs, targets Filipino Islamist guerrillas such as Abu Sayyaf have been described as "rooted in a distinct class made up of closely-knit networks built through the marriage of important families through socioeconomic backgrounds and family structures", according to Michael Buehler. This tight-knit, familial structure provides resilience but also limits their growth. Commander of the Western Mindanao Command Lieutenant General Rustico Guerrero, describes Abu Sayyaf as "a local group with a local agenda". Two kidnapping victims, (Martin and Gracia Burnham) who were kept in captivity by ASG for over a year, "gently engaged their captors in theological discussion" and found Abu Sayyaf fighters to be unfamiliar with the Qur'an. They had only "a sketchy" notion of Islam, which they saw as "a set of behavioural rules, to be violated when it suited them", according to author Mark Bowden. As "holy warriors, they were justified in kidnapping, killing and stealing. Having sex with women captives was justified by their claiming them as "wives". Unlike MILF and MNLF, the group is not recognised by the Organization of Islamic Cooperation, and according to author Robert East, was seen as "nothing more than a criminal operation" at least prior to 2001. A Center for Strategic and International Studies report by Jack Fellman notes the political rather than religious motivation of ASG. He quotes Khadaffy's statement that his brother was right to split from MNLF because "up to now, nothing came out" of attempts to gain more autonomy for Moro Muslims. This suggests, Fellman believes, that ASG "is merely the latest, albeit most violent, iteration of Moro political dissatisfaction that has existed for the last several decades". Some Abu Sayyaf members are also "shabu" (methamphetamine) users as described by surviving hostages who saw Abu Sayyaf members taking shabu as well from military findings who found drug packets in many of the abandoned Abu Sayyaf nests that justified their motivation as extreme criminals and terrorists as their state of mind were under the influence of drugs rather than being consciously fighting for the betterment of their region as well rights to living under their minority religion without any discrimination from the majority Filipinos. Its spokesman known as Abu Rami ( 2017) appeared to lack knowledge of the activities of other members, as the group had apparently separated into many small groups with their own leaders. Targets Most Abu Sayyaf victims have been Filipinos; however, in recent years (especially from 2011 onwards), Australian, British, Canadian, Chinese, Dutch, French, German, Indonesian, Japanese, Korean, Malaysian, Norwegian, Swiss and Vietnamese nationals have been kidnapped or attacked. Previously, Americans were particularly targeted. An unnamed ASG spokesman allegedly stated, "We have been trying hard to get an American because they may think we are afraid of them". He added, "We want to fight the American people." In 1993, Abu Sayyaf kidnapped an American Bible translator. In 2000, Abu Sayyaf captured an American Muslim and demanded that the United States release Sheikh Omar Abdel Rahman and Ramzi Yousef, who were jailed for their involvement in the 1993 World Trade Center bombing in New York City. Between March 2016 – July 2017, the majority of Abu Sayyaf kidnap for ransom operations shifted to the high seas. Seventeen ships were boarded and some sixty-five hostages from six countries were taken. In total, thirty hostages have been released (usually after a ransom was paid), seven escaped, three were rescued by Philippine security forces, and four were executed. Two others were killed during the attacks while eight seamen escaped during the shipjackings. An additional forty seamen were not taken hostage. Crimes and terrorism Abu Sayyaf has carried out numerous bombings, kidnappings, assassinations, and extortion activities. These include the 2000 Sipadan kidnappings, the 2001 Dos Palmas kidnappings and the 2004 SuperFerry 14 bombing. Kidnappings Although the group has engaged in kidnapping hostages to be exchanged for ransom for many years, this means of funding grew dramatically beginning in 2014, providing funds for the group's rapid growth. In the Philippines Journalists abducted since 2000 ABS-CBN's Newsbreak reported that Abu Sayyaf abducted at least 20 journalists from 2000 to 2008 (mostly foreign journalists). All of them were eventually released upon payment of ransom. GMA-7 television reporter Susan Enriquez (April 2000, Basilan, a few days); 10 Foreign journalists (7 German, 1 French, 1 Australian and 1 Danish, in May 2000, Jolo, for 10 hours); German Andreas Lorenz of the magazine Der Spiegel (July 2000, Jolo, for 25 days; he was also kidnapped in May); French television reporter Maryse Burgot and cameraman Jean-Jacques Le Garrec and sound technician Roland Madura (July 2000, Jolo, for 2 months); ABS-CBN television reporter Maan Macapagal and cameraman Val Cuenca (July 2000, Jolo, for 4 days); Philippine Daily Inquirer contributor and Net 25 television reporter Arlyn de la Cruz (January 2002, Zamboanga, for 3 months) GMA-7 television reporter Carlo Lorenzo and cameraman Gilbert Ordiales (September 2002, Jolo, for 6 days). Filipino Ces Drilon and news cameramen Jimmy Encarnacion and Angelo Valderrama released unharmed after ransom paid (June 2008 Maimbung, Sulu for 9 days; See 2008 Maimbung kidnappings). Jordanian TV journalist Baker Atyani and his two Filipino crews were kidnapped in June 2012 by the Abu Sayyaf militants they had sought to interview in the jungles of Sulu province. The two crew were freed in February 2013. Al Arabiya News Channel stated that their correspondent, Atyani, was handed over to the local governor's office on December 4, 2013. However, police and military officials could not ascertain whether Atyani had escaped from his captors or was freed. Jeffrey Schilling On August 31, 2000, American citizen and Muslim convert Jeffrey Schilling from Oakland, California, was captured on Jolo while visiting a terrorist camp with his new wife, Ivy Osani (a cousin of Abu Sabaya, one of the rebel leaders), whom he had met online. ASG demanded a $10 million ransom. Rebels also sarcastically threatened to behead him in 2001 as a "birthday present" to then Philippine President Gloria Macapagal Arroyo, who responded by declaring "all-out war" on them. The beheading threat was withdrawn after Schilling's mother, Carol, flew to the Philippines and appealed for mercy on local radio. On April 12, 2001, Philippine soldiers raided a rebel camp and rescued the American. The United States praised the Philippine government for freeing Schilling. Many commentators have been critical of Schilling, who claims to have walked willingly into the camp after he was invited by his wife's cousin, a member of Abu Sayyaf. Schilling was one of more than 40 hostages taken by Abu Sayyaf in 2000, including 21 tourists and workers seized in a raid on Sipadan diving resort in neighboring Malaysia. Many of the hostages were released after Libya paid millions of dollars. A Libyan official stated that Schilling had visited the Jolo camp often before his capture. Philippine intelligence sources say he was interested in selling military equipment to the rebels, while the bandits accused him of being a CIA agent. Abu Sayyaf threatened several times to kill Schilling. At one stage, Schilling reportedly went on a hunger strike to win his freedom. Martin and Gracia Burnham On May 27, 2001, an Abu Sayyaf raid kidnapped about 20 people from Dos Palmas, an expensive resort in Honda Bay, taking them to the north of Puerto Princesa City on the island of Palawan, which had been "considered completely safe". The most "valuable" hostages were three North Americans, Martin and Gracia Burnham, a missionary couple, and Guillermo Sobero, a Peruvian-American tourist who was later beheaded, following a $1 million ransom demand. The hostages and hostage-takers then returned to Abu Sayyaf territories in Mindanao. According to Bowden, the leader of the raid was Abu Sabaya. According to Gracia Burnham, she told her husband "to identify his kidnappers" to authorities "as 'the Osama bin Laden Group,' but Burnham was unfamiliar with that name and stuck with" Abu Sayyaf. After returning to Mindanao, Abu Sayyaf conducted numerous raids, including one that culminated in the Siege of Lamitan and "one at a coconut plantation called Golden Harvest; they took about 15 people captive there and later used bolo knives to hack the heads off two men. The number of hostages waxed and waned as some were ransomed and released, new ones were taken and others were killed." On June 7, 2002, about a year after the raid, Philippine army troops conducted a rescue operation in which Martin Burnham and Filipino nurse Ediborah Yap were killed. The remaining hostage was wounded and the hostage takers escaped. In July 2004, Gracia Burnham testified at a trial of eight Abu Sayyaf members and identified six of the suspects as her captors, including Alhamzer Limbong, Abdul Azan Diamla, Abu Khari Moctar, Bas Ishmael, Alzen Jandul, and Dazid Baize. "The eight suspects sat silently during her three-hour testimony, separated from her by a wooden grill. They face the death sentence if found guilty of kidnapping for ransom. The trial began this year and is not expected to end for several months." Alhamzer Limbong was later killed in a prison uprising. Burnham claimed that Philippine military officials were colluding with her captors, saying that the Armed Forces of the Philippines "didn't pursue us ... As time went on, we noticed that they never pursued us". 2007 Father Bossi kidnapping On June 10, 2007, Italian priest Reverend Giancarlo Bossi was kidnapped near Pagadian, capital of Zamboanga del Sur Province in the southern Philippines. Pope Benedict XVI made an appeal to free him. Bossi was released on July 19, 2007, at Karumatan, a Muslim town in Lanao del Norte Province, allegedly after the payment of ransom. Father Bossi died in Italy on September 23, 2012. In December 2020, Samad Awang, alias Ahmad Jamal, of the Abdussalam kidnap-for-ransom group was killed in a firefight with government troops in Zamboanga City. Awang was reportedly involved in the kidnapping of Italian missionary Fr. Giancarlo Bossi in 2007, businessman Joel Endino in 2011, and teacher Kathy Kasipong in 2013. 2009 Red Cross kidnapping On January 15, 2009, Abu Sayyaf kidnapped International Committee of the Red Cross (ICRC) delegates in Patikul, Sulu Province, Philippines. Three ICRC workers had finished conducting fieldwork in Sulu province, located in the southwest of the country when they were abducted by an unknown group, later confirmed as Albader Parad's group. All three were eventually released. According to a CNN story, Parad was reportedly killed, along with five other militants, in an assault by Philippine marines in Sulu province on Sunday, February 21, 2010. 2009 Irish priest kidnapping On October 11, 2009, Irish Catholic missionary Michael Sinnott, aged 79, from Barntown County Wexford was kidnapped from a gated compound in Pagadian, the capital of Zamboanga del Sur province, suspected to be part of ASG and some renegade members of MILF. Six kidnappers forced the priest into a mini-van and drove towards Sta. Lucia (district), where they transferred to a boat. Sinnott had a heart condition and was without medication when abducted. In early November, a demand for $US2 million ransom was made. On November 11, 2009, Father Sinnott was released in Zamboanga City. The Department of Foreign Affairs (Ireland) claimed that no ransom was paid by the Irish Government. 2010 Japanese treasure hunter On July 16, 2010, Japanese national Toshio Ito was kidnapped from Pangutaran, Sulu. At one point, the Philippine police believed the "treasure hunter", a Muslim convert also known by his Muslim name Mamaito Katayama, was acting as a cook for Abu Sayyaf; however, this was disputed by other nations, including the United States, which included him on its list of kidnap victims. A classified document obtained by Rappler lists Ito first, saying he was held captive by Abu Sayyaf's most senior leader, Radullan Sahiron, in Langpas, Indanan, Sulu early in 2013. 2011 Malaysian gecko trader On May 8, 2011, Malaysian gecko trader Mohammad Nasauddin Bin Saidin was kidnapped while hunting for gecko (tuko) in Indanan, Sulu. Saidin was freed on May 12, 2012. 2011 Indian national kidnapping On June 22, 2011, Indian national Biju Kolara Veetil was captured by four armed men while visiting his wife's relatives on the island of Jolo. A$10 million ransom was demanded. Veetil later denied that he was released in August 2012 because he had converted to Islam during captivity. Warren Rodwell Warren Richard Rodwell, a former Australian Army soldier and university English teacher, was shot through the right hand when seized from his home at Ipil, Zamboanga Sibugay on the island of Mindanao in the southern Philippines on December 5, 2011 by ASG militants. Rodwell later had to have a finger amputated. ASG threatened to behead Rodwell if their $US2 million ransom demand was not met. Both the Australian and Philippine governments had strict policies against paying ransoms. Australia formed a multi-agency task force to liaise with Rodwell's family and assist Philippine authorities. A news blackout was imposed. Filipino politicians helped negotiate the release. After the payment of $AUD94,000 for "board and lodging" expenses by his siblings, Rodwell was released on March 23, 2013. Arrests and killings On June 16, 2014, suspects Jimmy Nurilla (alias Doc) and Bakrin Haris were arrested. Both reportedly worked under Basilan-based Abu Sayyaf leader Khair Mundos and Furuji Indama. Authorities believed Nurilla and Haris took part in the Rodwell kidnapping, as well as the separate abduction of US citizen Gerfa Yeatts Lunsman and her son Kevin in 2012. In January 2015, Mindanao Examiner newspaper reported the arrest of Barahama Ali kidnap gang sub-leaders linked to the kidnapping of Rodwell, who was seized by at least 5 gunmen (disguised as policemen), and eventually handed over or sold by the kidnappers to the Abu Sayyaf in Basilan province. In May 2015, ex-Philippine National Police (PNP) officer Jun A. Malban, alias Michael Zoo, was arrested in Kota Kinabalu, Malaysia, for the crime of "Kidnapping for Ransom" after Rodwell identified him as the negotiator/spokesperson. Further PNP investigation revealed that Malban is the cousin of Abu Sayyaf leaders Khair and Borhan Mundos (both of whom were arrested in 2014). The director of the Anti-Kidnapping Group (AKG) stated that Malban's arrest resulted from close co-ordination by the PNP, National Bureau of Investigation (Philippines) and Presidential Anti-Organized Crime Commission with the Malaysian counterparts and through Interpol. In January 2018, Rodwell attended a court hearing for Malban and others in Ipil, Zamboanga Sibugay, pursuant to a Supreme Court petition to transfer his case for security reasons to a court in either Manila or Zamboanga City. In August 2015, Edeliza Sumbahon Ulep, alias Gina Perez, was arrested at Trento, Agusan del Sur during a joint manhunt operation by police and military units. Ulep was tagged as the ransom courier in the kidnapping. In August 2016, The Manila Times reported the arrest of the kidnap-for-ransom group of Barahama Alih sub-leader, Hasim Calon alias Husien (also a notorious drug dealer), in his hideout in Tenan village in Ipil town. Hasim Calon was involved in Rodwell's abduction. Earlier in 2016, police forces killed Waning Abdulsalam, a former MILF leader, in the village of Singkilon. Abdulsalam was one of the most wanted criminals in the southern Philippines and connected to ASG. He was linked to the kidnappings of Rodwell in 2011, Irish missionary Michael Sinnott in 2009 in Pagadian City, and Italian Catholic priest Giancarlo Bossi in Zamboanga del Sur's Payao town in 2007. In March 2019, combined security forces of the 44th Infantry Battalion, Philippine National Police, Philippine Drugs Enforcement Agency, National Bureau of Investigation and Philippine Coast Guard arrested five members (Benhazer Anduhol, Solaiman Calonof, Nicanel Maningo, Jay-ar Abba Quartocruz and Hashim Lucas Samdani) of Barahama Alih criminal gang during drug operations with warrants in Barangay Tenan of Ipil town, Zamboanga Sibugay. Military sources allege Barahama Alih Group was responsible for a number of kidnapping incidents in previous years including the abduction of Australian national Warren Rodwell, Italian priest Giancarlo Bossi, and some local Filipinos. In February 2018, Abu Sayyaf sub-commander Nurhassan Jamiri was reported by Malaysia regional intelligence sources as one of three gunmen killed in a gunfight with police in Sabah. Jamiri was atop the Philippines' most wanted list and implicated in dozens of ransom kidnappings including Rodwell. In March 2018, Jamiri turned up alive when he and thirteen followers surrendered to authorities in Basilan. Over the preceding two years, many Abu Sayyaf bandits had surrendered to authorities in Basilan, Sulu, and Tawi-Tawi. More were expected to yield because of the regional government's Program Against Violence and Extremism (PAVE), designed to provide opportunities and interventions, including psychosocial sessions, medical check-ups, introduction to farming systems, and expository tours outside the island provinces to facilitate the reintegration of former combatants into society. In April 2018, Rodwell lauded the surrenders and reintegration program, but said he would not interfere with the legal processing of any charges already filed against anyone involved with his own kidnapping. In June 2020, Inquirer newspaper reported the killing of Mamay Aburi by government troops in Titay, Zamboanga Sibugay after authorities attended to serve a warrant of arrest. Aburi was allegedly a subleader of a kidnap-for-ransom group and had been linked with the Abu Sayyaf Group based in Sulu. The provincial director of the Criminal Investigation and Detection Group (CIDG) said Aburi was involved in the 2011 kidnapping of Australian national Warren Rodwell and the 2019 abduction of the Hyrons couple in Tukuran, Zamboanga del Sur. In February 2021, The Manila Times reported that Abu Sayyaf subleader Arrasid Halissam was shot dead when he opened fire on police serving a warrant on him in the village of Santa Maria, Zamboanga City. Halissam was linked to numerous kidnappings such as Australian adventurer Warren Rodwell, Americans Gerfa Lunsmann and son Kevin, Chinese Yuan Lin Kai and Jian Luo, South Korean Nwi Seong Hong, and almost a dozen Filipinos. Halissam was also allegedly involved in the 2015 bombing in Zamboanga that killed two people and injured over fifty others. 2012 European bird watchers On February 1, 2012, two European bird watchers were seized on Tawi Tawi island. Swiss Lorenzo Vinciguerra escaped in December 2014 as government troops attacked the jungle camp where he was captive on the island of Jolo. Vinciguerra was shot by rebels as he escaped; however, his injuries were non-life-threatening. Dutch captive Ewold Horn was reportedly unable to escape. The whereabouts of Horn remained unknown. On May 31, 2019, Western Mindanao Command confirmed that Horn was shot dead during a clash with military in Patikul, Sulu. Additionally, the military advised that the wife of ASG leader Radulan Sahiron and five other ASG members were also killed. 2012 Mayor Jeffrey Lim Kidnapping On April 2, 2012, Mayor Jeffrey Lim of Salug, Zamboanga del Norte was kidnapped by ten armed men disguised as policemen. Lim was reportedly handed over to Abu Sayyaf. On November 6, he was freed near Zamboanga City after payment of P1.3M ($US25,000) ransom. On August 9, 2013, a Mindanao Pagadian Frontline report named a "Sehar Muloc" aka "Red Eye" as a suspect in the 2012 kidnapping of Mayor Jeffrey Lim. Abner Gumandol, alias Sehar Muloc and Red Eye, was said to be the leader of a criminal syndicate called the Muloc Group. Gumandol was arrested on June 12, 2016. 2014 Kabasalan ZSP kidnapping On September 11, 2014, Chinese national Li Pei Zhei was abducted by four gunmen in Kabasalan, Zamboanga Sibugay and taken to Basilan. He was released in Sitio Lugay-Lugay, Barangay Naga-Naga, Alicia, Zamboanga Sibugay on November 5, 2014. Police subsequently charged Ibni Basaludin, Yug Enriquez, Brahama Ali, and Ging-Ging Calon, all residents of Barangay Tenan, Ipil, Zamboanga Sibugay with kidnapping with serious illegal detention. 2015 Roseller Lim ZSP kidnapping On January 24, 2015, Korean national Nwi Seong Hong was abducted by armed men in Roseller Lim, Zamboanga Sibugay Province. The victim's son, Abby, escaped after he fought off the kidnappers. According to intelligence information from the JTG-SULU, the captors of were Algabsy Misaya, Idang Susukan, Alden Bagade and Mohammad Salud alias Ama Maas, Indanan-based members led by sub-leaders Isang Susukan and Anga Adji. On October 31, 2015, the body of 74-year-old Nwi Seong Hong was found in Barangay Bangkal, Patikul, Sulu. Investigators said the victim died due to severe illness. 2015 Samal Island kidnappings On September 21, 2015, Canadians Robert Hall and John Ridsdel, as well as Norwegian Kjartan Sekkingstad, and (Hall's girlfriend) Marites Flor; a Filipino woman, were abducted on Samal Island near Davao. Ridsdel was beheaded by Abu Sayyaf on April 25, 2016, following a ransom deadline. ASG reportedly demanded more than $8.1 million for Ridsdel and the others. On May 3, 2016, a video of the Ridsdel execution was released, along with new demands for the remaining hostages. A masked captor said, "Note to the Philippine government and to the Canadian government: The lesson is clear. John Ridsdel has been beheaded. Now there are three remaining captives here. If you procrastinate once again the negotiations, we will behead this all anytime". On May 15, Hall appeared in a new video, announcing that he and Norwegian Kjartan Sekkingstad would be decapitated at 3 pm on Monday June 13 absent a ransom of $16 million. Both hostages wore orange coveralls, similar to hostages in videos produced by IS, to which Abu Sayyaf had previously pledged allegiance. The deadline passed. Hall was beheaded. On June 24, Abu Sayyaf released Filipina Marites Flor. She was subsequently flown to Davao to meet President-elect Rodrigo Duterte. Duterte said he directed negotiations with the Abu Sayyaf. He did not elaborate. On September 17, 2016, remaining hostage Norwegian Kjartan Sekkingstad was released on Jolo island. Abu Rami, an ASG spokesman, claimed $638,000 was paid as ransom. 2015 Dipolog kidnapping On October 7, 2015, Italian national and pizza restaurant owner Rolando del Torchio was kidnapped in Dipolog, the capital of Zamboanga del Norte. On April 8, 2016, Del Torchio was released and found at Jolo port aboard MV KC Beatrice bound for Zamboanga City after his family paid P29 million ($US650,000) in ransom. 2019 Tukuran kidnapping On October 4, 2019, armed men abducted British national Allan Hyrons and his Filipino wife Wilma from their beach resort in Tukuran town, Zamboanga del Sur province on the southern island of Mindanao. After a brief exchange of gunfire in November between Abu Sayyaf and Philippine troops on the island of Jolo, the couple was abandoned and rescued. No ransom was reportedly paid. In Malaysia 2000 Sipadan kidnappings On May 3, 2000, Abu Sayyaf guerrillas occupied the Malaysian dive resort island Sipadan and took 21 hostages, including 10 tourists and 11 resort workers – 19 foreign nationals in total. The hostages were taken to an Abu Sayyaf base in Jolo. Two Muslim Malaysians were released soon after. Abu Sayyaf made various demands for the release of several prisoners, including 1993 World Trade Center bomber Ramzi Yousef and $2.4 million. In July, a Filipino television evangelist and 12 of members of the Jesus Miracle Crusade Church offered their help and went as mediators for the relief of other hostages. They, three French television crew members and a German journalist, all visiting Abu Sayyaf on Jolo, were also taken hostage. Most hostages were released in August and September 2000, partly due to mediation by Libyan leader Muammar Gaddafi and an offer of $25 million in "development aid". Abu Sayyaf conducted a second raid on the island of Pandanan near Sipadan on September 10 and seized three more Malaysians. The Philippine army launched a major offensive on September 16, 2000, rescuing all remaining hostages, except Filipino dive instructor Roland Ullah. He was freed in 2003. Abu Sayyaf coordinated with the Chinese 14K Triad gang in carrying out the kidnappings. The 14K Triad has militarily supported Abu Sayyaf. 2013 Pom Pom kidnappings On November 15, 2013, Abu Sayyaf militants raided a resort on the Malaysian island of Pom Pom. During the ambush, Taiwanese citizen Chang An-wei was kidnapped and her husband, Hsu Li-min, was killed. Chang was taken to the Sulu Archipelago. Chang was freed in Sulu Province and returned to Taiwan on December 21. 2014 Singamata, Baik Island and Kampung Air Sapang kidnappings On April 2, 2014, a kidnap gang believed to originate from Abu Sayyaf militants raided Singamata Reef Resort off Semporna. Chinese tourist Gao Huayun from Shanghai and Filipino resort worker Marcy Dayawan were abducted and taken to the Sulu Archipelago. The two hostages were later rescued after a collaboration between Malaysian and Philippines security forces. On May 6, five Abu Sayyaf gunmen raided a Malaysian fish farm on Baik Island Sabah, kidnapped the fish farm manager and took him to Jolo island. He was freed in July with the help of Malaysian negotiators. On June 16, two gunmen believed to be from Abu Sayyaf kidnapped a Chinese fish farm manager and one Filipino worker in Kampung Air Sapang. The worker managed to escape and disappeared. Meanwhile, the fish farm manager was taken to Jolo. He was released on December 10.

On November 8, Thien Nyuk Fun, the seafood restaurant owner, was released after payment of 30 million pesos ($US675,000) ransom. The initial agreement of 30 million pesos was reportedly for both hostages; however, a faction within the Abu Sayyaf Group demanded more after Thien Nyuk Fun was released. Further negotiations broke down and the other hostage, electrical engineer Bernard Then, was beheaded on Jolo Island on November 17. Philippines and Malaysia waters 2014 German sailors kidnapping In April 2014, Germans Dr. Stefan Viktor Okonek and Henrike Dielen were captured on their yacht on the high seas near Borneo. Abu Sayyaf threatened to behead one of them. After payment of $US5.6 million in October 2014, the pair were released in Patikul, Sulu. 2016 Local and foreign sailors kidnappings On March 26, 2016, ten Indonesian seafarers were held hostage by ASG operating in Sulu Archipelago. They were abducted from the Brahma 12 tugboat and the Anand 12 barge near Tawi-Tawi province. The Indonesian vessels were freighting coal from South Borneo heading for Batangas port when hijacked. In April, the Indonesian government announced that the company that owned tugboat Brahma 12 had agreed to pay the 50-million-peso ($1 million) ransom. On May 2, they were released. On April 1, four Malaysian sailors aboard a tugboat from Manila were kidnapped when they arrived near the shore of Ligitan Island. Their companions, three Myanmar nationals and two Indonesians, were unharmed. On June 8, they were released. On April 15, four Indonesian sailors were kidnapped when two Indonesian tugboats from Cebu, Henry and Cristi, were attacked by Abu Sayyaf militants. While five of the passengers were safe, one was shot before he was rescued. They were released on May 11. A group of concerned Filipinos in Sabah urged Philippine president-elect Rodrigo Duterte to intervene for the release of four Malaysians held hostage by Abu Sayyaf. The issue strained the relationship between the Philippines and Malaysia. On June 21, seven Indonesian sailors were kidnapped while aboard a tugboat passing through the Sulu Archipelago. On July 9, three Indonesian fishermen were kidnapped near the coast of Lahad Datu, Sabah, Malaysia and released on September 17. On July 18, five Malaysian sailors were abducted near the coast of Lahad Datu. On August 3, an Indonesian sailor was kidnapped in the waters of Malaysia leaving two other crew members unharmed. This incident was reported by victims on August 5. Two of the hostages managed to escape after receiving persistent threats of beheading. On September 10, three Filipino fishermen were kidnapped on the shores of Pom Pom Island. On September 22, another Indonesian hostage was released. On September 27, one Malaysian boat-skipper was kidnapped from his trawler by seven armed militants before the group attacked another Indonesian trawler; however, no kidnappings were committed in the second incident. The hostage was released on October 1, with no ransom demand, along with three Indonesians hostages who were released the same day. On October 21, approximately ten Abu Sayyaf militants attacked a South Korean-bound vessel named MV Dongbang Gian and abducted a South Korean skipper and a Filipino crewman off Bongao, Tawi-Tawi. On November 5, German sailor Sabine Merz was shot dead while her husband Jürgen Kantner was abducted from their yacht off Tanjong Luuk Pisuk in Sabah. On or before February 27, 2017, Kantner was beheaded after a ransom of 30 million pesos ($US600,000) was not paid. On November 11, Vietnamese vessel MV Royale 16 with nineteen sailors on board was attacked by Abu Sayyaf near Basilan, abducting six sailors and injuring one. The remaining thirteen sailors were released. On November 20, two Indonesian fishermen were kidnapped by five gunmen off Lahad Datu. Due to the increase of attacks against foreign vessels by Abu Sayyaf, the governments of Indonesia, Malaysia, and the Philippines agreed to jointly patrol their waters on May 5, 2016. The three countries formed another agreement on joint air patrols. During the first six months of 2016, Abu Sayyaf made $7.3 million, equivalent to Php 353 million, from ransom payoffs. Beheadings As part of its kidnap-for-ransom operations, the Abu Sayyaf has executed some of their male hostages if ransom demands were not met. The group had previously beheaded Christian civilians and others they consider kafir without demanding ransoms for their release, due to their religious affiliation. Bombings 2004 Superferry 14 Bombing Superferry 14 was a large ferry destroyed by a bomb on February 27, 2004, killing 116 people in the Philippines' worst terrorist attack and the world's deadliest terrorist attack at sea. On that day, the 10,192 ton ferry sailed out of Manila with about 900 passengers and crew on board. A television set filled with 8 lb. (4 kilograms) of TNT had been placed on board. 90 minutes out of port, the bomb exploded. 63 people were killed instantly and 53 were missing and presumed dead. Despite claims from terrorist groups, the blast was initially thought to have been an accident caused by a gas explosion. However, after divers righted the ferry five months after it had sunk, they found evidence of a bomb blast. A man called Redendo Cain Dellosa admitted to planting the bomb for Abu Sayyaf. Six suspects were arrested in connection with the bombing while the masterminds, Khadaffy Janjalani and Abu Sulaiman, were killed. 2016 Davao City bombing On September 2, 2016, an explosion occurred at a night market in Davao City, Philippines killing at least 15 and injuring 70. Shortly before the bombing, Abu Sayyaf made a threat following the intensified military operation against them. Abu Sayyaf spokesperson Abu Rami was reported to claim responsibility. He later denied the report and any involvement, saying a group allied to them; the Daulat Ul-Islamiya were responsible. Although the Abu Sayyaf spokesman denied involvement, the Philippine government blame the group. 2019 Jolo Cathedral bombings On January 27, 2019, two bombs detonated at the Roman Catholic Cathedral of Our Lady of Mount Carmel in Jolo town which is the center of Abu Sayyaf stronghold. The bombings resulting to eighteen people were killed while 82 others were injured, mostly from Philippine Army's 35th Battalion and civilians inside the church. The Philippine military said the Abu Sayyaf under the faction of Ajang-Ajang are responsible which is also echoed by peace advocate with evidence from military intelligence operatives that they have intercepted plans of the latter to bomb the other parts of downtown Jolo months before. The bombings took place a week after a referendum for the creation of Bangsamoro Autonomous Region with the attacks is described as the opposition by the Abu Sayyaf group for their areas inclusion under the Bangsamoro authorities since the whole Sulu province itself is already known to be against the referendum with 163,526 oppose votes (54.3%). Criticism of attacks against civilians Sheikh Yusuf al-Qaradawi in Qatar denounced the kidnappings and killings committed by Abu Sayyaf, asserting that they are not part of the dispute between the Abu Sayyaf and the Philippine government. He stated that it is shameful to commit such acts in the name of the Islamic faith, saying that such acts produce backlash against Islam and Muslims. During the 2000 Sipadan kidnappings, the Organization of the Islamic Conference (OIC) condemned the kidnapping and offered to help secure their release. OIC Secretary General Azeddine Laraki, told the Philippine government he was prepared to send an envoy to help save the hostages and issued a statement condemning the rebels. "The Secretary General has pointed out that this operation and the like are rejected by divine laws and that they are neither the appropriate nor correct means to resolve conflicts", the statement said. The terrorism against civilians committed were condemned by MNLF and MILF, who said that Abu Sayyaf strayed from their real paths of struggle, with MILF labeling Abu Sayyaf as "anti-Islam" soon after Ridsdel's beheading in 2016. MNLF described the group as "causing chaos to their community". Both Christian and Muslim groups in the Philippines condemned Abu Sayyaf beheadings. The kidnappings were criticized by Indonesia. On July 14, 2016, a group of Indonesian protesters gathered in front of the Philippine Embassy in Jakarta, holding banners that read "Go to hell Philippines and Abu Sayyaf" and "Destroy the Philippines and Abu Sayyaf" due to what was seen as the lack of action from the Philippine government. The group demanded a large scale military operation to destroy the Abu Sayyaf, with the Indonesian military proposing to send its forces to the Philippines prior to the protest, only to be rejected by the Philippine government on constitutional grounds. Military operations The Philippine military has engaged Abu Sayyaf since the 1990s. Under President Duterte, the Philippine government sought a peace agreement with the MNLF and MILF, but not the "bunch of criminals" in Abu Sayyaf. The Philippine military intensified operations in 2003, following the arrest of a Filipino-American who was alleged to have sold illegal weapons to the group. The suspect was tagged by US authorities as "one of the United States' most wanted fugitives". He was then deported by the Philippine government to face legal action in the United States. On July 29, 2016, the military gained control of an Abu Sayyaf stronghold in Tipo-Tipo. The Philippine military pledged to eliminate Abu Sayyaf. On August 25, President Duterte ordered the group to be "destroyed" after it beheaded a teenager. Following the incident, the Philippine military sent thousands of troops to fight and destroy Abu Sayyaf. Filipino Army Major Filemon Tan said, "The order of the president is to search and destroy the Abu Sayyaf so that's what we are doing". Both MNLF and MILF began helping to suppress extremism in Mindanao, which helps the peace process for both groups. Philippine security forces collaborated with Malaysia and Indonesia to maintain security in the Sulu Sea. The Indonesian government proposed to station army units in Mindanao to launch a major offensive against Abu Sayyaf. The Indonesian government called on the Malaysian and Philippine armies to launch combined land attacks together on Mindanao, while at the same time urging the Philippine government to allow Indonesia and Malaysia military forces to enter Philippine territory. The Vietnamese military started to hold military exercises against Abu Sayyaf (known locally as "pirates" by the Vietnamese) following the repeat kidnappings of Malaysian and Indonesian sailors. The Philippine military provided one battalion to go against each subgroup. On September 9, following the meeting between President Duterte and Indonesian President Joko Widodo, an agreement was reached to pursue the Abu Sayyaf. The Philippine President said in a statement: However, the government of Indonesia decided to not launch a military operation in the southern Philippines, stating that there is enough Philippine military personnel had been deployed. Indonesia's view was seconded by Malaysia. Philippine military chief Ricardo Visaya warned the Abu Sayyaf that they would continue with further major military operations. The military chief gave notice to Abu Sayyaf members to surrender or be "neutralised", (killed or apprehended). Some 20 Abu Sayyaf surrendered in Sumisip on September 22. The day before, Philippine armed forces confiscated 200 speedboats used by the Abu Sayyaf in Basilan, Sulu, Tawi-Tawi and Zamboanga. President Duterte rejected a proposal by Nur Misuari, the leader of MNLF to include Abu Sayyaf in peace talks. On September 27, another attempt to smuggle weapons to Abu Sayyaf was prevented by the Philippine National Police in San Juan City. Four people were arrested. By October 14, the Philippine military had launched 579 military operations, 426 of which were focused to "neutralise" group members. 54 engagements resulted in 56 Abu Sayyaf members killed, 21 surrendered and 17 arrested. Abu Sayyaf fatalities then increased to 102, with seven more apprehended. Notable Abu Sayyaf leaders were killed, including Nelson Muktadil, Braun Muktadil, their sub-leader Mohammad Said, Jamiri Jawhari, Musanna Jamiri, the group spokesman Abu Rami and Alhabsy Misaya. In addition, another 165 fast boats used for transport and kidnapping activities were confiscated. By April 13, 2017, 50 more ASG members had surrendered. In the same month, Philippine authorities discovered the presence of militants from Indonesia and Malaysia killed during the ongoing operations (notable foreigners such as Sanusi, Zulkifli Abdhir, Ibrahim Ali, Mohd Najib Husen and Mohisen were among the dead) as well the presence of a "traitor" among their security members when a top policewoman was caught for her ties with the group. Indonesia admitted the presence of its citizens who came from North Sulawesi and said they could not prevent them from joining, given the lack of security on their borders. Malaysia discovered that militants were using Sabah as a transit point. The two pledged to prevent cross-border terrorism and curb the activities of militants Early on November 26, 2016, Duterte stated that he would open peace talks with Abu Sayyaf group (as he did with the MNLF and MILF by offering federalism as a possible solution) while continuing to fight against the Maute group, a move criticized by Philippine analysts as it would be used by extreme rebels to claim for legitimacy as a group. In a statement, the President said: His statements were criticized by national media as leading to confusion about whether he wanted peace talks. Another IS-linked group, the Maute emerged in 2016. On December 7, Duterte told the Indonesian and Malaysian leaders that "they can bomb the Abu Sayyaf along with the hostages if the Abu Sayyaf continue to present persistent threats and the hostages should already know that there is repeated warnings to not go there". In early 2019, Duterte emphatically stated that he would never initiate or agree to any peace talks with Abu Sayyaf due to his detestation for the group's record of atrocities and its treatment of innocent people as young as 8 years old. In the aftermath of the 2019 Jolo Cathedral bombings, President Duterte ordered an "All-Out-War" directive against the Abu Sayyaf Group, which led to heavy ground operations, massive airstrikes, artillery bombardment in surrounding areas, the evacuation of civilian in other areas, and the creation of the 11th Infantry Division of the Philippine Army.

Armenian ( (reformed), (classical), , ) is an Indo-European language and the sole member of an independent branch of that language family. It is the native language of the Armenian people and the official language of Armenia. Historically spoken in the Armenian highlands, today Armenian is widely spoken throughout the Armenian diaspora. Armenian is written in its own writing system, the Armenian alphabet, introduced in 405 AD by the canonized saint Mesrop Mashtots. The estimated number of Armenian speakers worldwide is between five and seven million. History Classification and origins Armenian is an independent branch of the Indo-European languages. It is of interest to linguists for its distinctive phonological changes within that family. Armenian exhibits more satemization than centumization, although it is not classified as belonging to either of these subgroups. Some linguists tentatively conclude that Armenian, Greek (and Phrygian) and Indo-Iranian were dialectally close to each other; within this hypothetical dialect group, Proto-Armenian was situated between Proto-Greek (centum subgroup) and Proto-Indo-Iranian (satem subgroup). Ronald I. Kim has noted unique morphological developments connecting Armenian to Balto-Slavic languages. The Armenian language has a long literary history, with a 5th-century Bible translation as its oldest surviving text. Its vocabulary has historically been influenced by Western Middle Iranian languages, particularly Parthian; its derivational morphology and syntax were also affected by language contact with Parthian, but to a lesser extent. Contact with Greek, Persian, and Syriac also resulted in a number of loanwords. There are two standardized modern literary forms, Eastern Armenian (spoken mainly in Armenia) and Western Armenian (spoken originally mainly in modern-day Turkey and, since the Armenian genocide, mostly in the diaspora). The differences between them are considerable but they are mutually intelligible after significant exposure. Some subdialects such as Homshetsi are not mutually intelligible with other varieties. Although Armenians were known to history much earlier (for example, they were mentioned in the 6th-century BC Behistun Inscription and in Xenophon's 4th century BC history, The Anabasis), the oldest surviving Armenian-language writing is etched in stone on Armenian temples and is called Mehenagir. The Armenian alphabet was created by Mesrop Mashtots in 405, at which time it had 36 letters. He is also credited by some with the creation of the Georgian alphabet and the Caucasian Albanian alphabet. While Armenian constitutes the sole member of the Armenian branch of the Indo-European family, Aram Kossian has suggested that the hypothetical Mushki language may have been a (now extinct) Armenic language. Early contacts W. M. Austin (1942) concluded that there was early contact between Armenian and Anatolian languages, based on what he considered common archaisms, such as the lack of a feminine gender and the absence of inherited long vowels. Unlike shared innovations (or synapomorphies), the common retention of archaisms (or symplesiomorphy) is not considered conclusive evidence of a period of common isolated development. There are words used in Armenian that are generally believed to have been borrowed from Anatolian languages, particularly from Luwian, although some researchers have identified possible Hittite loanwords as well. One notable loanword from Anatolian is Armenian xalam, "skull", cognate to Hittite ḫalanta, "head". In 1985, the Soviet linguist Igor M. Diakonoff noted the presence in Classical Armenian of what he calls a "Caucasian substratum" identified by earlier scholars, consisting of loans from the Kartvelian and Northeast Caucasian languages. Noting that Hurro-Urartian-speaking peoples inhabited the Armenian homeland in the second millennium BC, Diakonoff identifies in Armenian a Hurro-Urartian substratum of social, cultural, and animal and plant terms such as ałaxin "slave girl" ( ← Hurr. al(l)a(e)ḫḫenne), cov "sea" ( ← Urart. ṣûǝ "(inland) sea"), ułt "camel" ( ← Hurr. uḷtu), and xnjor "apple (tree)" ( ← Hurr. ḫinzuri). Some of the terms he gives admittedly have an Akkadian or Sumerian provenance, but he suggests they were borrowed through Hurrian or Urartian. Given that these borrowings do not undergo sound changes characteristic of the development of Armenian from Proto-Indo-European, he dates their borrowing to a time before the written record but after the Proto-Armenian language stage. Contemporary linguists, such as Hrach Martirosyan, have rejected many of the Hurro-Urartian and Northeast Caucasian origins for these words and instead suggest native Armenian etymologies, leaving the possibility that these words may have been loaned into Hurro-Urartian and Caucasian languages from Armenian, and not vice versa. A notable example is arciv, meaning "eagle", believed to have been the origin of Urartian Arṣibi and Northeast Caucasian arzu. This word is derived from Proto-Indo-European *h₂r̥ǵipyós, with cognates in Sanskrit (ऋजिप्य, ṛjipyá), Avestan (ərəzifiia), and Greek (αἰγίπιος, aigípios). Hrach Martirosyan and Armen Petrosyan propose additional borrowed words of Armenian origin loaned into Urartian and vice versa, including grammatical words and parts of speech, such as Urartian eue ("and"), attested in the earliest Urartian texts and likely a loan from Armenian (compare to Armenian , ultimately from Proto-Indo-European *h₁epi). Other loans from Armenian into Urartian includes personal names, toponyms, and names of deities. Loan words from Iranian languages, along with the other ancient accounts such as that of Xenophon above, initially led linguists to erroneously classify Armenian as an Iranian language. Scholars such as Paul de Lagarde and F. Müller believed that the similarities between the two languages meant that Armenian belonged to the Iranian language family. The distinctness of Armenian was recognized when philologist Heinrich Hübschmann (1875) used the comparative method to distinguish two layers of Iranian words from the older Armenian vocabulary. He showed that Armenian often had two morphemes for one concept, that the non-Iranian components yielded a consistent Proto-Indo-European pattern distinct from Iranian, and that the inflectional morphology was different from that of Iranian languages. Graeco-Armenian hypothesis The hypothesis that Greek is Armenian's closest living relative originates with Holger Pedersen (1924), who noted that the number of Greek-Armenian lexical cognates is greater than that of agreements between Armenian and any other Indo-European language. Antoine Meillet (1925, 1927) further investigated morphological and phonological agreement and postulated that the parent languages of Greek and Armenian were dialects in immediate geographical proximity during the Proto-Indo-European period. Meillet's hypothesis became popular in the wake of his book Esquisse d'une histoire de la langue latine (1936). Georg Renatus Solta (1960) does not go as far as postulating a Proto-Graeco-Armenian stage, but he concludes that considering both the lexicon and morphology, Greek is clearly the dialect to be most closely related to Armenian. Eric P. Hamp (1976, 91) supports the Graeco-Armenian thesis and even anticipates a time "when we should speak of Helleno-Armenian" (meaning the postulate of a Graeco-Armenian proto-language). Armenian shares the augment and a negator derived from the set phrase in the Proto-Indo-European language ("never anything" or "always nothing"), the representation of word-initial laryngeals by prothetic vowels, and other phonological and morphological peculiarities with Greek. Nevertheless, as Fortson (2004) comments, "by the time we reach our earliest Armenian records in the 5th century AD, the evidence of any such early kinship has been reduced to a few tantalizing pieces". Greco-Armeno-Aryan hypothesis Graeco-(Armeno)-Aryan is a hypothetical clade within the Indo-European family, ancestral to the Greek language, the Armenian language, and the Indo-Iranian languages. Graeco-Aryan unity would have become divided into Proto-Greek and Proto-Indo-Iranian by the mid-3rd millennium BC. Conceivably, Proto-Armenian would have been located between Proto-Greek and Proto-Indo-Iranian, consistent with the fact that Armenian shares certain features only with Indo-Iranian (the satem change) but others only with Greek (s > h). Graeco-Aryan has comparatively wide support among Indo-Europeanists who believe the Indo-European homeland to be located in the Armenian Highlands, the "Armenian hypothesis". Early and strong evidence was given by Euler's 1979 examination on shared features in Greek and Sanskrit nominal flection. Used in tandem with the Graeco-Armenian hypothesis, the Armenian language would also be included under the label Aryano-Greco-Armenic, splitting into Proto-Greek/Phrygian and "Armeno-Aryan" (ancestor of Armenian and Indo-Iranian). Evolution Classical Armenian (Arm: grabar), attested from the 5th century to the 19th century as the literary standard (up to the 11th century also as a spoken language with different varieties), was partially superseded by Middle Armenian, attested from the 12th century to the 18th century. Specialized literature prefers "Old Armenian" for grabar as a whole, and designates as "Classical" the language used in the 5th century literature, "Post-Classical" from the late 5th to 8th centuries, and "Late Grabar" that of the period covering the 8th to 11th centuries. Later, it was used mainly in religious and specialized literature, with the exception of a revival during the early modern period, when attempts were made to establish it as the language of a literary renaissance, with neoclassical inclinations, through the creation and dissemination of literature in varied genres, especially by the Mekhitarists. The first Armenian periodical, Azdarar, was published in grabar in 1794. The classical form borrowed numerous words from Middle Iranian languages, primarily Parthian, and contains smaller inventories of loanwords from Greek, Syriac, Aramaic, Arabic, Mongol, Persian, and indigenous languages such as Urartian. An effort to modernize the language in Bagratid Armenia and the Armenian Kingdom of Cilicia (11–14th centuries) resulted in the addition of two more characters to the alphabet ("" and ""), bringing the total number to 38. The Book of Lamentations by Gregory of Narek (951–1003) is an example of the development of a literature and writing style of Old Armenian by the 10th century. In addition to elevating the literary style and vocabulary of the Armenian language by adding well above a thousand new words, through his other hymns and poems Gregory paved the way for his successors to include secular themes and vernacular language in their writings. The thematic shift from mainly religious texts to writings with secular outlooks further enhanced and enriched the vocabulary. "A Word of Wisdom", a poem by Hovhannes Sargavak devoted to a starling, legitimizes poetry devoted to nature, love, or female beauty. Gradually, the interests of the population at large were reflected in other literary works as well. Konsdantin Yerzinkatsi and several others took the unusual step of criticizing the ecclesiastic establishment and addressing the social issues of the Armenian homeland. These changes represented the nature of the literary style and syntax, but they did not constitute immense changes to the fundamentals of the grammar or the morphology of the language. Often, when writers codify a spoken dialect, other language users are then encouraged to imitate that structure through the literary device known as parallelism. In the 19th century, the traditional Armenian homeland was once again divided. This time Eastern Armenia was conquered from Qajar Iran by the Russian Empire, while Western Armenia, containing two thirds of historical Armenia, remained under Ottoman control. The antagonistic relationship between the Russian and Ottoman empires led to creation of two separate and different environments under which Armenians lived. Halfway through the 19th century, two important concentrations of Armenian communities were further consolidated. Because of persecutions or the search for better economic opportunities, many Armenians living under Ottoman rule gradually moved to Istanbul, whereas Tbilisi became the center of Armenians living under Russian rule. These two cosmopolitan cities very soon became the primary poles of Armenian intellectual and cultural life. The introduction of new literary forms and styles, as well as many new ideas sweeping Europe, reached Armenians living in both regions. This created an ever-growing need to elevate the vernacular, Ashkharhabar, to the dignity of a modern literary language, in contrast to the now-anachronistic Grabar. Numerous dialects existed in the traditional Armenian regions, which, different as they were, had certain morphological and phonetic features in common. On the basis of these features two major standards emerged: Western standard: The influx of immigrants from different parts of the traditional Armenian homeland to Istanbul crystallized the common elements of the regional dialects, paving the way for a style of writing that required a shorter and more flexible learning curve than Grabar. Eastern standard: The Yerevan dialect provided the primary elements of Eastern Armenian, centered in Tbilisi, Georgia. Similar to the Western Armenian variant, the Modern Eastern was in many ways more practical and accessible to the masses than Grabar. Both centers vigorously pursued the promotion of Ashkharhabar. The proliferation of newspapers in both versions (Eastern & Western) and the development of a network of schools where modern Armenian was taught, dramatically increased the rate of literacy (in spite of the obstacles by the colonial administrators), even in remote rural areas. The emergence of literary works entirely written in the modern versions increasingly legitimized the language's existence. By the turn of the 20th century both varieties of the one modern Armenian language prevailed over Grabar and opened the path to a new and simplified grammatical structure of the language in the two different cultural spheres. Apart from several morphological, phonetic, and grammatical differences, the largely common vocabulary and generally analogous rules of grammatical fundamentals allows users of one variant to understand the other as long as they are fluent in one of the literary standards. After World War I, the existence of the two modern versions of the same language was sanctioned even more clearly. The Armenian Soviet Socialist Republic (1920–1990) used Eastern Armenian as its official language, whereas the diaspora created after the Armenian genocide preserved the Western Armenian dialect. The two modern literary dialects, Western (originally associated with writers in the Ottoman Empire) and Eastern (originally associated with writers in the Russian Empire), removed almost all of their Turkish lexical influences in the 20th century, primarily following the Armenian genocide. Geographic distribution In addition to Armenia and Turkey, where it is indigenous, Armenian is spoken among the diaspora. According to Ethnologue, globally there are million Western Armenian speakers and million Eastern Armenian speakers, totalling million Armenian speakers. In Georgia, Armenian speakers are concentrated in Ninotsminda and Akhalkalaki districts where they represent over 90% of the population. Status and usage The short-lived First Republic of Armenia declared Armenian its official language. Eastern Armenian was then dominating in institutions and among the population. When Armenia was incorporated into the USSR, the Armenian Soviet Socialist Republic made Eastern Armenian the language of the courts, government institutions and schools. Armenia was also russified. The current Republic of Armenia upholds the official status of the Armenian language. Eastern Armenian is the official variant used, making it the prestige variety while other variants have been excluded from national institutions. Indeed, Western Armenian is perceived by some as a mere dialect. Armenian is also official in the Republic of Artsakh. It is recognized as an official language of the Eurasian Economic Union although Russian is the working language. Armenian (without reference to a specific variety) is officially recognized as a minority language in Cyprus, Hungary, Iraq, Poland, Romania, and Ukraine. It is recognized as a minority language and protected in Turkey by the 1923 Treaty of Lausanne. Western Armenian is the language of the diaspora, it is the medium of instruction in the majority of Armenian-language schools outside Armenia. In particular, in the Samtskhe-Javakheti region of Georgia, although Armenian has no legal status, there were 144 state-funded schools in the area as of 2010 where Armenian is the main language of instruction. The Lebanese curriculum allows Armenian schools to teach the Armenian language as a basic language. In California, home to a large Armenian American community, various state government agencies provide Armenian translations of their documents: the California Department of Social Services, California Department of Motor Vehicles, California superior courts. In the city of Glendale, there are street signs in Armenian. In Iran, article 15 of the constitution allows the use of "regional and tribal languages" in the mass media as well as within the schools. However, these languages do not receive formal status and are not officially regulated by the authorities. Iranian Armenians are de facto the only non-Persian ethnic group in Iran enjoying this right. They have their own private schools, where Armenian is the medium of instruction. Phonology Proto-Indo-European voiceless stop consonants are aspirated in the Proto-Armenian language, one of the circumstances that is often linked to the glottalic theory, a version of which postulated that some voiceless occlusives of Proto-Indo-European were aspirated. Stress In Armenian, the stress falls on the last syllable unless the last syllable contains the definite article or , and the possessive articles and , in which case it falls on the penultimate one. For instance, , , but and . Exceptions to this rule are some words with the final letter ( in the reformed orthography) () and sometimes the ordinal numerals (, etc.), as well as , and a small number of other words. Vowels Modern Armenian has six monophthongs. Each vowel phoneme in the table is represented by three symbols. The first is the sounds transcription in the International Phonetic Alphabet (IPA). After that appears the corresponding letter of the Armenian alphabet. The last symbol is its Latin transliteration. Western and other dialects may also have /, /. Consonants The following table lists the Eastern Armenian consonantal system. The occlusives and affricates have an aspirated series, commonly transcribed with a reversed apostrophe after the letter. Each phoneme in the table is represented by IPA, Armenian script and romanization. The major phonetic difference between dialects is in the reflexes of Classical Armenian voice-onset time. The seven dialect types have the following correspondences, illustrated with the t–d series: {| class="wikitable" style=text-align:center |+Correspondence in initial position !Armenian Letter |Թ |Տ |Դ |- !Indo-European |* |* |* |- !Karin, Sebastia | rowspan="7" | | | |- !Istanbul |colspan=2| |- !Kharberd, Middle Armenian | rowspan="2" | | |- !Malatya, SWA | |- !Classical Armenian, Agulis, SEA, Yerevan | | |- !Van, Artsakh |colspan=2| |} Morphology Armenian corresponds with other Indo-European languages in its structure, but it shares distinctive sounds and features of its grammar with neighboring languages of the Caucasus region. The Armenian orthography is rich in combinations of consonants, but in pronunciation, this is broken up with schwas. Both classical Armenian and the modern spoken and literary dialects have a complicated system of noun declension, with six or seven noun cases but no gender. In modern Armenian, the use of auxiliary verbs to show tense (comparable to will in "he will go") has generally supplanted the inflected verbs of Classical Armenian. Negative verbs are conjugated differently from positive ones (as in English "he goes" and "he does not go") in many tenses, otherwise adding only the negative to the positive conjugation. Grammatically, early forms of Armenian had much in common with classical Greek and Latin, but the modern language, like modern Greek, has undergone many transformations, adding some analytic features. Noun Armenian has no grammatical gender, not even in the pronoun, but there is a feminine suffix ( "-uhi"). For example, (usucʻičʻ, "teacher") becomes (usucʻčʻuhi, female teacher). This suffix does not have a grammatical effect on the sentence. The nominal inflection reserves several types of inherited stem classes. Historically, nouns were declined for one of seven cases: nominative (ուղղական uġġakan), accusative (հայցական haycʻakan), locative (ներգոյական nergoyakan), genitive (սեռական seṙakan), dative (տրական trakan), ablative (բացառական bacʻaṙakan), or instrumental (գործիական gorciakan), but in the modern language, the nominative and accusative cases, as well as the dative and genitive cases, have merged. Examples of noun declension in Eastern Armenian Which case the direct object takes is split based on animacy (a phenomenon more generally known as differential object marking). Inanimate nouns take the nominative, while animate nouns take the dative. Additionally, animate nouns can never take the locative case. Examples of noun declension in Western Armenian Verb Verbs in Armenian have an expansive system of conjugation with two main verb types in Eastern Armenian and three in Western Armenian changing form based on tense, mood and aspect. Dialects Armenian is a pluricentric language, having two modern standardized forms: Eastern Armenian and Western Armenian. The most distinctive feature of Western Armenian is that it has undergone several phonetic mergers; these may be due to proximity to Arabic- and Turkish-speaking communities. Classical Armenian (Grabar), which remained the standard until the 18th century, was quite homogeneous across the different regions that works in it were written; it may have been a cross-regional standard. The Middle Armenian variety used in the court of Cilician Armenia (1080–1375) provides a window into the development of Western Armenian, which came to be based on what became the dialect of Istanbul, while the standard for Eastern Armenian was based on the dialect around Mount Ararat and Yerevan. Although the Armenian language is often divided into "east" and "west", the two standards are actually relatively close to each other in light of wealth of the diversity present among regional non-standard Armenian dialects. The different dialects have experienced different degrees of language contact effects, often with Turkic and Caucasian languages; for some, the result has been significant phonological and syntactic changes. Fortson notes that the modern standard as well has now attained a subordinate clausal structure that greatly resembles a Turkic language. Eastern Armenian speakers pronounce () as [tʰ], () as [d], and () as a tenuis occlusive [t˭]. Western Armenian has simplified the occlusive system into a simple division between voiced occlusives and aspirated ones; the first series corresponds to the tenuis series of Eastern Armenian, and the second corresponds to the Eastern voiced and aspirated series. Thus, the Western dialect pronounces both () and () as [tʰ], and the () letter as [d]. There is no precise linguistic border between one dialect and another because there is nearly always a dialect transition zone of some size between pairs of geographically identified dialects. Armenian can be divided into two major dialectal blocks and those blocks into individual dialects, though many of the Western Armenian dialects have become extinct due to the effects of the Armenian genocide. In addition, neither dialect is completely homogeneous: any dialect can be subdivided into several subdialects. Although Western and Eastern Armenian are often described as different dialects of the same language, many subdialects are not readily mutually intelligible. Nevertheless, a fluent speaker of one of two greatly varying dialects who is also literate in one of the standards, when exposed to the other dialect for a period of time will be able to understand the other with relative ease. Distinct Western Armenian varieties currently in use include Homshetsi, spoken by the Hemshin peoples; the dialects of Armenians of Kessab (Քեսապի բարբառ), Latakia and Jisr al-Shughur (Syria), Anjar, Lebanon, and Vakıflı, Samandağ (Turkey), part of the "Sueidia" dialect (Սուէտիայի բարբառ). Forms of the Karin dialect of Western Armenian are spoken by several hundred thousand people in Northern Armenia, mostly in Gyumri, Artik, Akhuryan, and around 130 villages in Shirak Province, and by Armenians in Samtskhe–Javakheti province of Georgia (Akhalkalaki, Akhaltsikhe). Nakhichevan-on-Don Armenians speak another Western Armenian variety based on the dialect of Armenians in Crimea, where they came from in order to establish the town and surrounding villages in 1779 (Նոր Նախիջևանի բարբառ). Western Armenian dialects are currently spoken also in Gavar (formerly Nor Bayazet and Kamo, on the western shore of Lake Sevan), Aparan, and Talin in Armenia (Mush dialect), and by the large Armenian population residing in Abkhazia, where they are considered to be the first or second ethnic minority, or even equal in number to the local Abkhaz population Orthography The Armenian alphabet ( or ) is a graphically unique alphabetical writing system that is used to write the Armenian language. It was introduced around AD 405 by Mesrop Mashtots, an Armenian linguist and ecclesiastical leader, and originally contained 36 letters. Two more letters, օ (ō) and ֆ (f), were added in the Middle Ages. During the 1920s orthography reform in Soviet Armenia, a new letter և (capital ԵՎ) was added, which was a ligature before ե+ւ, whereas the letter Ւ ւ was discarded and reintroduced as part of a new letter ՈՒ ու (which was a digraph before). This alphabet and associated orthography is used by most Armenian speakers of Armenia and the countries of the former Soviet Union. Neither the alphabet nor the orthography has been adopted by Diaspora Armenians, including Eastern Armenian speakers of Iran and all Western Armenian speakers, who keep using the traditional alphabet and spelling. Vocabulary Indo-European cognates Armenian is an Indo-European language, so many of its Proto-Indo-European-descended words are cognates of words in other Indo-European languages such as English, Latin, Greek, and Sanskrit. Due to extensive loaning, only around 1,500 words (G. Jahukyan) are known to have been inherited from Indo-European by the Classical Armenian stage; the rest were lost, a fact that presents a major challenge to endeavors to better understand Proto-Armenian and its place within the family, especially as many of the sound changes along the way from Indo-European to Armenian remain quite difficult to analyze.

Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. The timbre of musical instruments can be considered in the light of Fourier theory to consist of multiple harmonic or inharmonic partials or overtones. Each partial is a sine wave of different frequency and amplitude that swells and decays over time due to modulation from an ADSR envelope or low frequency oscillator. Additive synthesis most directly generates sound by adding the output of multiple sine wave generators. Alternative implementations may use pre-computed wavetables or the inverse fast Fourier transform. Explanation The sounds that are heard in everyday life are not characterized by a single frequency. Instead, they consist of a sum of pure sine frequencies, each one at a different amplitude. When humans hear these frequencies simultaneously, we can recognize the sound. This is true for both "non-musical" sounds (e.g. water splashing, leaves rustling, etc.) and for "musical sounds" (e.g. a piano note, a bird's tweet, etc.). This set of parameters (frequencies, their relative amplitudes, and how the relative amplitudes change over time) are encapsulated by the timbre of the sound. Fourier analysis is the technique that is used to determine these exact timbre parameters from an overall sound signal; conversely, the resulting set of frequencies and amplitudes is called the Fourier series of the original sound signal. In the case of a musical note, the lowest frequency of its timbre is designated as the sound's fundamental frequency. For simplicity, we often say that the note is playing at that fundamental frequency (e.g. "middle C is 261.6 Hz"), even though the sound of that note consists of many other frequencies as well. The set of the remaining frequencies is called the overtones (or the harmonics, if their frequencies are integer multiples of the fundamental frequency) of the sound. In other words, the fundamental frequency alone is responsible for the pitch of the note, while the overtones define the timbre of the sound. The overtones of a piano playing middle C will be quite different from the overtones of a violin playing the same note; that's what allows us to differentiate the sounds of the two instruments. There are even subtle differences in timbre between different versions of the same instrument (for example, an upright piano vs. a grand piano). Additive synthesis aims to exploit this property of sound in order to construct timbre from the ground up. By adding together pure frequencies (sine waves) of varying frequencies and amplitudes, we can precisely define the timbre of the sound that we want to create. Definitions Harmonic additive synthesis is closely related to the concept of a Fourier series which is a way of expressing a periodic function as the sum of sinusoidal functions with frequencies equal to integer multiples of a common fundamental frequency. These sinusoids are called harmonics, overtones, or generally, partials. In general, a Fourier series contains an infinite number of sinusoidal components, with no upper limit to the frequency of the sinusoidal functions and includes a DC component (one with frequency of 0 Hz). Frequencies outside of the human audible range can be omitted in additive synthesis. As a result, only a finite number of sinusoidal terms with frequencies that lie within the audible range are modeled in additive synthesis. A waveform or function is said to be periodic if for all and for some period . The Fourier series of a periodic function is mathematically expressed as: where is the fundamental frequency of the waveform and is equal to the reciprocal of the period, is the amplitude of the th harmonic, is the phase offset of the th harmonic. atan2 is the four-quadrant arctangent function, Being inaudible, the DC component, , and all components with frequencies higher than some finite limit, , are omitted in the following expressions of additive synthesis. Harmonic form The simplest harmonic additive synthesis can be mathematically expressed as: where is the synthesis output, , , and are the amplitude, frequency, and the phase offset, respectively, of the th harmonic partial of a total of harmonic partials, and is the fundamental frequency of the waveform and the frequency of the musical note. Time-dependent amplitudes More generally, the amplitude of each harmonic can be prescribed as a function of time, , in which case the synthesis output is Each envelope should vary slowly relative to the frequency spacing between adjacent sinusoids. The bandwidth of should be significantly less than . Inharmonic form Additive synthesis can also produce inharmonic sounds (which are aperiodic waveforms) in which the individual overtones need not have frequencies that are integer multiples of some common fundamental frequency. While many conventional musical instruments have harmonic partials (e.g. an oboe), some have inharmonic partials (e.g. bells). Inharmonic additive synthesis can be described as where is the constant frequency of th partial. Time-dependent frequencies In the general case, the instantaneous frequency of a sinusoid is the derivative (with respect to time) of the argument of the sine or cosine function. If this frequency is represented in hertz, rather than in angular frequency form, then this derivative is divided by . This is the case whether the partial is harmonic or inharmonic and whether its frequency is constant or time-varying. In the most general form, the frequency of each non-harmonic partial is a non-negative function of time, , yielding Broader definitions Additive synthesis more broadly may mean sound synthesis techniques that sum simple elements to create more complex timbres, even when the elements are not sine waves. For example, F. Richard Moore listed additive synthesis as one of the "four basic categories" of sound synthesis alongside subtractive synthesis, nonlinear synthesis, and physical modeling. In this broad sense, pipe organs, which also have pipes producing non-sinusoidal waveforms, can be considered as a variant form of additive synthesizers. Summation of principal components and Walsh functions have also been classified as additive synthesis. Implementation methods Modern-day implementations of additive synthesis are mainly digital. (See section Discrete-time equations for the underlying discrete-time theory) Oscillator bank synthesis Additive synthesis can be implemented using a bank of sinusoidal oscillators, one for each partial. Wavetable synthesis In the case of harmonic, quasi-periodic musical tones, wavetable synthesis can be as general as time-varying additive synthesis, but requires less computation during synthesis. As a result, an efficient implementation of time-varying additive synthesis of harmonic tones can be accomplished by use of wavetable synthesis. Group additive synthesis Group additive synthesis is a method to group partials into harmonic groups (having different fundamental frequencies) and synthesize each group separately with wavetable synthesis before mixing the results. Inverse FFT synthesis An inverse fast Fourier transform can be used to efficiently synthesize frequencies that evenly divide the transform period or "frame". By careful consideration of the DFT frequency-domain representation it is also possible to efficiently synthesize sinusoids of arbitrary frequencies using a series of overlapping frames and the inverse fast Fourier transform. Additive analysis/resynthesis It is possible to analyze the frequency components of a recorded sound giving a "sum of sinusoids" representation. This representation can be re-synthesized using additive synthesis. One method of decomposing a sound into time varying sinusoidal partials is short-time Fourier transform (STFT)-based McAulay-Quatieri Analysis. By modifying the sum of sinusoids representation, timbral alterations can be made prior to resynthesis. For example, a harmonic sound could be restructured to sound inharmonic, and vice versa. Sound hybridisation or "morphing" has been implemented by additive resynthesis. Additive analysis/resynthesis has been employed in a number of techniques including Sinusoidal Modelling, Spectral Modelling Synthesis (SMS), and the Reassigned Bandwidth-Enhanced Additive Sound Model. Software that implements additive analysis/resynthesis includes: SPEAR, LEMUR, LORIS, SMSTools, ARSS. Products New England Digital Synclavier had a resynthesis feature where samples could be analyzed and converted into "timbre frames" which were part of its additive synthesis engine. Technos acxel, launched in 1987, utilized the additive analysis/resynthesis model, in an FFT implementation. Also a vocal synthesizer, Vocaloid have been implemented on the basis of additive analysis/resynthesis: its spectral voice model called Excitation plus Resonances (EpR) model is extended based on Spectral Modeling Synthesis (SMS), and its diphone concatenative synthesis is processed using spectral peak processing (SPP) technique similar to modified phase-locked vocoder (an improved phase vocoder for formant processing). Using these techniques, spectral components (formants) consisting of purely harmonic partials can be appropriately transformed into desired form for sound modeling, and sequence of short samples (diphones or phonemes) constituting desired phrase, can be smoothly connected by interpolating matched partials and formant peaks, respectively, in the inserted transition region between different samples. (See also Dynamic timbres) Applications Musical instruments Additive synthesis is used in electronic musical instruments. It is the principal sound generation technique used by Eminent organs. Speech synthesis In linguistics research, harmonic additive synthesis was used in 1950s to play back modified and synthetic speech spectrograms. Later, in early 1980s, listening tests were carried out on synthetic speech stripped of acoustic cues to assess their significance. Time-varying formant frequencies and amplitudes derived by linear predictive coding were synthesized additively as pure tone whistles. This method is called sinewave synthesis. Also the composite sinusoidal modeling (CSM) used on a singing speech synthesis feature on Yamaha CX5M (1984), is known to use a similar approach which was independently developed during 1966–1979. These methods are characterized by extraction and recomposition of a set of significant spectral peaks corresponding to the several resonance modes occurred in the oral cavity and nasal cavity, in a viewpoint of acoustics. This principle was also utilized on a physical modeling synthesis method, called modal synthesis. History Harmonic analysis was discovered by Joseph Fourier, who published an extensive treatise of his research in the context of heat transfer in 1822. The theory found an early application in prediction of tides. Around 1876, William Thomson (later ennobled as Lord Kelvin) constructed a mechanical tide predictor. It consisted of a harmonic analyzer and a harmonic synthesizer, as they were called already in the 19th century. The analysis of tide measurements was done using James Thomson's integrating machine. The resulting Fourier coefficients were input into the synthesizer, which then used a system of cords and pulleys to generate and sum harmonic sinusoidal partials for prediction of future tides. In 1910, a similar machine was built for the analysis of periodic waveforms of sound. The synthesizer drew a graph of the combination waveform, which was used chiefly for visual validation of the analysis. Georg Ohm applied Fourier's theory to sound in 1843. The line of work was greatly advanced by Hermann von Helmholtz, who published his eight years worth of research in 1863. Helmholtz believed that the psychological perception of tone color is subject to learning, while hearing in the sensory sense is purely physiological. He supported the idea that perception of sound derives from signals from nerve cells of the basilar membrane and that the elastic appendages of these cells are sympathetically vibrated by pure sinusoidal tones of appropriate frequencies. Helmholtz agreed with the finding of Ernst Chladni from 1787 that certain sound sources have inharmonic vibration modes. In Helmholtz's time, electronic amplification was unavailable. For synthesis of tones with harmonic partials, Helmholtz built an electrically excited array of tuning forks and acoustic resonance chambers that allowed adjustment of the amplitudes of the partials. Built at least as early as in 1862, these were in turn refined by Rudolph Koenig, who demonstrated his own setup in 1872. For harmonic synthesis, Koenig also built a large apparatus based on his wave siren. It was pneumatic and utilized cut-out tonewheels, and was criticized for low purity of its partial tones. Also tibia pipes of pipe organs have nearly sinusoidal waveforms and can be combined in the manner of additive synthesis. In 1938, with significant new supporting evidence, it was reported on the pages of Popular Science Monthly that the human vocal cords function like a fire siren to produce a harmonic-rich tone, which is then filtered by the vocal tract to produce different vowel tones. By the time, the additive Hammond organ was already on market. Most early electronic organ makers thought it too expensive to manufacture the plurality of oscillators required by additive organs, and began instead to build subtractive ones. In a 1940 Institute of Radio Engineers meeting, the head field engineer of Hammond elaborated on the company's new Novachord as having a "subtractive system" in contrast to the original Hammond organ in which "the final tones were built up by combining sound waves". Alan Douglas used the qualifiers additive and subtractive to describe different types of electronic organs in a 1948 paper presented to the Royal Musical Association. The contemporary wording additive synthesis and subtractive synthesis can be found in his 1957 book The electrical production of music, in which he categorically lists three methods of forming of musical tone-colours, in sections titled Additive synthesis, Subtractive synthesis, and Other forms of combinations. A typical modern additive synthesizer produces its output as an electrical, analog signal, or as digital audio, such as in the case of software synthesizers, which became popular around year 2000. Timeline The following is a timeline of historically and technologically notable analog and digital synthesizers and devices implementing additive synthesis. Discrete-time equations In digital implementations of additive synthesis, discrete-time equations are used in place of the continuous-time synthesis equations. A notational convention for discrete-time signals uses brackets i.e. and the argument can only be integer values. If the continuous-time synthesis output is expected to be sufficiently bandlimited; below half the sampling rate or , it suffices to directly sample the continuous-time expression to get the discrete synthesis equation. The continuous synthesis output can later be reconstructed from the samples using a digital-to-analog converter. The sampling period is . Beginning with (), and sampling at discrete times results in where is the discrete-time varying amplitude envelope is the discrete-time backward difference instantaneous frequency.

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increases the time of availability on the combat zone. There is no single definition of an "aircraft carrier", and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, and sometimes as distinct types of naval aviation-capable ships. Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, RN, former First Sea Lord (head) of the Royal Navy, has said, "To put it simply, countries that aspire to strategic international influence have aircraft carriers." Henry Kissinger, while United States Secretary of State, also said: "An aircraft carrier is 100,000 tons of diplomacy." As of , there are 47 active aircraft carriers in the world operated by fourteen navies. The United States Navy has 11 large nuclear-powered fleet carriers—carrying around 80 fighters each—the largest carriers in the world; the total combined deck space is over twice that of all other nations combined. As well as the aircraft carrier fleet, the US Navy has nine amphibious assault ships used primarily for helicopters, although these also each carry up to 20 vertical or short take-off and landing (V/STOL) fighter jets and are similar in size to medium-sized fleet carriers. The United Kingdom, India and China each operate two aircraft carriers. France and Russia each operate a single aircraft carrier with a capacity of 30 to 60 fighters. Italy operates two light V/STOL carriers and Spain operates one V/STOL aircraft-carrying assault ship. Helicopter carriers are operated by Japan (4, two of which are being converted to operate V/STOL fighters), France (3), Australia (2), Egypt (2), South Korea (2), China (3), Thailand (1) and Brazil (1). Future aircraft carriers are under construction or in planning by China, France, India, Russia, South Korea, Turkey, and the US. Types of carriers General features Speed is a crucial attribute for aircraft carriers, as they need to be able to be deployed quickly anywhere in the world and have to be fast enough to evade detection and targeting from enemy forces. A high speed also increases the "wind over the deck", boosting the lift available for fixed-wing aircraft to carry fuel and ammunition. In order to evade nuclear submarines, the carriers should have a speed of more than 30 knots. Aircraft carriers are among the largest types of warships due to their need for ample deck space. An aircraft carrier must be able to perform increasingly diverse mission sets. Diplomacy, power projection, quick crisis response force, land attack from the sea, sea base for helicopter and amphibious assault forces, anti-surface warfare (ASUW), Defensive Counter Air (DCA), and humanitarian aid disaster relief (HADR) are some of the missions the aircraft carrier is expected to accomplish. Traditionally an aircraft carrier is supposed to be one ship that can perform at least power projection and sea control missions. An aircraft carrier must be able to efficiently operate an air combat group. This means it should handle fixed-wing jets as well as helicopters. This includes ships designed to support operations of short-takeoff/vertical-landing (STOVL) jets. Basic types Aircraft cruiser Amphibious assault ship and sub-types Anti-submarine warfare carrier Balloon carrier and balloon tenders Escort carrier Fleet carrier Flight deck cruiser Helicopter carrier Light aircraft carrier Sea Control Ship Seaplane tender and seaplane carriers Utility carrier: This type was mainly used in the US Navy, in the decade after World War 2 to ferry aircraft. Some of the types listed here are not strictly defined as aircraft carriers by some sources. By role A fleet carrier is intended to operate with the main fleet and usually provides an offensive capability. These are the largest carriers capable of fast speeds. By comparison, escort carriers were developed to provide defense for convoys of ships. They were smaller and slower with lower numbers of aircraft carried. Most were built from mercantile hulls or, in the case of merchant aircraft carriers, were bulk cargo ships with a flight deck added on top. Light aircraft carriers were fast enough to operate with the main fleet but of smaller size with reduced aircraft capacity. The Soviet aircraft carrier Admiral Kusnetsov was termed a "heavy aircraft-carrying cruiser". This was primarily a legal construct to avoid the limitations of the Montreux Convention preventing 'aircraft carriers' transiting the Turkish Straits between the Soviet Black Sea bases and the Mediterranean Sea. These ships, while sized in the range of large fleet carriers, were designed to deploy alone or with escorts. In addition to supporting fighter aircraft and helicopters, they provide both strong defensive weaponry and heavy offensive missiles equivalent to a guided-missile cruiser. By configuration Aircraft carriers today are usually divided into the following four categories based on the way that aircraft take off and land: Catapult-assisted take-off barrier-arrested recovery (CATOBAR): these carriers generally carry the largest, heaviest, and most heavily armed aircraft, although smaller CATOBAR carriers may have other limitations (weight capacity of aircraft elevator, etc.). All CATOBAR carriers in service today are nuclear powered. Twelve are in service: ten Nimitz and one fleet carriers in the United States; and the Charles de Gaulle in France. Short take-off barrier-arrested recovery (STOBAR): these carriers are generally limited to carrying lighter fixed-wing aircraft with more limited payloads. STOBAR carrier air wings, such as the Sukhoi Su-33 and future Mikoyan MiG-29K wings of are often geared primarily towards air superiority and fleet defense roles rather than strike/power projection tasks, which require heavier payloads (bombs and air-to-ground missiles). Five are in service: two in China; two in India and one in Russia. Short take-off vertical-landing (STOVL): limited to carrying STOVL aircraft. STOVL aircraft, such as the Harrier family and Yakovlev Yak-38 generally have limited payloads, lower performance, and high fuel consumption when compared with conventional fixed-wing aircraft; however, a new generation of STOVL aircraft, currently consisting of the Lockheed Martin F-35B Lightning II, has much improved performance. Fourteen are in service; nine STOVL amphibious assault ships in the US; two carriers each in Italy and the UK; and one STOVL amphibious assault ship in Spain. Helicopter carrier: Helicopter carriers have a similar appearance to other aircraft carriers but operate only helicopters – those that mainly operate helicopters but can also operate fixed-wing aircraft are known as STOVL carriers (see above). Seventeen are in service: four in Japan; three in France; two each in Australia, China, Egypt and South Korea; and one each in Brazil and Thailand. In the past, some conventional carriers were converted and these were called "commando carriers" by the Royal Navy. Some helicopter carriers, but not all, are classified as amphibious assault ships, tasked with landing and supporting ground forces on enemy territory. By size Fleet carrier Light aircraft carrier Escort carrier Supercarrier The appellation "supercarrier" is not an official designation with any national navy, but a term used predominantly by the media and typically when reporting on larger and more advanced carrier types. It is also used when comparing carriers of various sizes and capabilities, both current and past. It was first used by The New York Times in 1938, in an article about the Royal Navy's , that had a length of , a displacement of 22,000 ton and was designed to carry 72 aircraft. Since then, aircraft carriers have consistently grown in size, both in length and displacement, as well as improved capabilities; in defense, sensors, electronic warfare, propulsion, range, launch and recovery systems, number and types of aircraft carried and number of sorties flown per day. China, Russia, and the United Kingdom all have carriers in service or under construction with displacements ranging from 65,000 to 85,000 tons and lengths from which have been described as "supercarriers". The largest "supercarriers" in service as of 2022, however, are with the US Navy, with displacements exceeding 100,000 tons, lengths of over , and capabilities that match or exceed that of any other class. Hull type identification symbols Several systems of identification symbol for aircraft carriers and related types of ship have been used. These include the pennant numbers used by the Royal Navy, Commonwealth countries, and Europe, along with the hull classification symbols used by the US and Canada. History Origins The 1903 advent of the heavier-than-air fixed-wing airplane with the Wright brothers' first flight at Kitty Hawk, North Carolina, was closely followed on 14 November 1910, by Eugene Burton Ely's first experimental take-off of a Curtiss Pusher airplane from the deck of a United States Navy ship, the cruiser anchored off Norfolk Navy Base in Virginia. Two months later, on 18 January 1911, Ely landed his Curtiss Pusher airplane on a platform on the armored cruiser anchored in San Francisco Bay. On 9 May 1912, the first take off of an airplane from a ship while underway was made by Commander Charles Samson flying a Short Improved S.27 biplane "S.38" of the Royal Naval Air Service (RNAS) from the deck of the Royal Navy's pre-dreadnought battleship , thus providing the first practical demonstration of the aircraft carrier for naval operations at sea. Seaplane tender support ships came next, with the French of 1911. Early in World War I, the Imperial Japanese Navy ship conducted the world's first successful ship-launched air raid: on 6 September 1914, a Farman aircraft launched by Wakamiya attacked the Austro-Hungarian cruiser and the Imperial German gunboat Jaguar in Jiaozhou Bay off Qingdao; neither was hit. The first attack using an air-launched torpedo occurred on 2 August, when a torpedo was fired by Flight Commander Charles H. K. Edmonds from a Short Type 184 seaplane, launched from the seaplane carrier . The first carrier-launched airstrike was the Tondern raid in July 1918. Seven Sopwith Camels were launched from the battlecruiser which had been completed as a carrier by replacing her planned forward turret with a flight deck and hangar prior to commissioning. The Camels attacked and damaged the German airbase at Tondern, Germany (modern day Tønder, Denmark) and destroyed two zeppelin airships. The first landing of an airplane on a moving ship was by Squadron Commander Edwin Harris Dunning, when he landed his Sopwith Pup on HMS Furious in Scapa Flow, Orkney on 2 August 1917. Landing on the forward flight deck required the pilot to approach round the ship's superstructure, a difficult and dangerous manoeuver and Dunning was later killed when his airplane was thrown overboard while attempting another landing on Furious. HMS Furious was modified again when her rear turret was removed and another flight deck added over a second hangar for landing aircraft over the stern. Her funnel and superstructure remained intact however and turbulence from the funnel and superstructure was severe enough that only three landing attempts were successful before further attempts were forbidden. This experience prompted the development of vessels with a flush deck and produced the first large fleet ships. In 1918, became the world's first carrier capable of launching and recovering naval aircraft. As a result of the Washington Naval Treaty of 1922, which limited the construction of new heavy surface combat ships, most early aircraft carriers were conversions of ships that were laid down (or had served) as different ship types: cargo ships, cruisers, battlecruisers, or battleships. These conversions gave rise to the US s (1927), Japanese and , and British . Specialist carrier evolution was well underway, with several navies ordering and building warships that were purposefully designed to function as aircraft carriers by the mid-1920s. This resulted in the commissioning of ships such as the Japanese (1922), (1924, although laid down in 1918 before Hōshō), and (1927). During World War II, these ships would become known as fleet carriers. World War II The aircraft carrier dramatically changed naval warfare in World War II, because air power was becoming a significant factor in warfare. The advent of aircraft as focal weapons was driven by the superior range, flexibility, and effectiveness of carrier-launched aircraft. They had greater range and precision than naval guns, making them highly effective. The versatility of the carrier was demonstrated in November 1940, when launched a long-range strike on the Italian fleet at their base in Taranto, signalling the beginning of the effective and highly mobile aircraft strikes. This operation in the shallow water harbor incapacitated three of the six anchored battleships at a cost of two torpedo bombers. World War II in the Pacific Ocean involved clashes between aircraft carrier fleets. The Japanese surprise attack on the American Pacific fleet at Pearl Harbor naval and air bases on Sunday, 7 December 1941, was a clear illustration of the power projection capability afforded by a large force of modern carriers. Concentrating six carriers in a single unit turned naval history about, as no other nation had fielded anything comparable. Further versatility was demonstrated during the "Doolittle Raid", on 18 April 1942, when US Navy carrier sailed to within of Japan and launched 16 B-25 bombers from her deck in a retaliatory strike on the mainland, including the capital, Tokyo. However, the vulnerability of carriers compared to traditional battleships when forced into a gun-range encounter was quickly illustrated by the sinking of by German battleships during the Norwegian campaign in 1940. This new-found importance of naval aviation forced nations to create a number of carriers, in efforts to provide air superiority cover for every major fleet in order to ward off enemy aircraft. This extensive usage led to the development and construction of 'light' carriers. Escort aircraft carriers, such as , were sometimes purpose-built but most were converted from merchant ships as a stop-gap measure to provide anti-submarine air support for convoys and amphibious invasions. Following this concept, light aircraft carriers built by the US, such as , represented a larger, more "militarized" version of the escort carrier. Although with similar complement to escort carriers, they had the advantage of speed from their converted cruiser hulls. The UK 1942 Design Light Fleet Carrier was designed for building quickly by civilian shipyards and with an expected service life of about 3 years. They served the Royal Navy during the war, and the hull design was chosen for nearly all aircraft carrier equipped navies after the war, until the 1980s. Emergencies also spurred the creation or conversion of highly unconventional aircraft carriers. CAM ships were cargo-carrying merchant ships that could launch (but not retrieve) a single fighter aircraft from a catapult to defend the convoy from long range land-based German aircraft. Postwar era Before World War II, international naval treaties of 1922, 1930, and 1936 limited the size of capital ships including carriers. Since World War II, aircraft carrier designs have increased in size to accommodate a steady increase in aircraft size. The large, modern of US Navy carriers has a displacement nearly four times that of the World War II–era , yet its complement of aircraft is roughly the same—a consequence of the steadily increasing size and weight of individual military aircraft over the years. Today's aircraft carriers are so expensive that some nations which operate them risk significant economic and military impact if a carrier is lost. Some changes were made after 1945 in carriers: The angled flight deck was invented by Royal Navy Captain (later Rear Admiral) Dennis Cambell, as naval aviation jets higher speeds required carriers be modified to "fit" their needs. Additionally, the angled flight deck allows for simultaneous launch and recovery. Jet blast deflectors became necessary to protect aircraft and handlers from jet blast. The first US Navy carriers to be fitted with them were the wooden-decked s which were adapted to operate jets in the late 1940s. Later versions had to be water-cooled because of increasing engine power. Optical landing systems were developed to facilitate the very precise landing angles required by jet aircraft, which have a faster landing speed giving the pilot little time to correct misalignments, or mistakes. The first system was fitted to in 1952. Aircraft carrier designs have increased in size to accommodate continuous increase in aircraft size. The 1950s saw US Navy's commission of "supercarriers", designed to operate naval jets, which offered better performance at the expense of bigger size and demanded more ordnance to be carried on-board (fuel, spare parts, electronics, etc.). The combination of increased carrier size, speed requirements above 30 knots, and a requirement to operate at sea for long periods mean that modern large aircraft carriers often use nuclear reactors to create power for propulsion, electricity, catapulting airplanes from aircraft carriers, and a few more minor uses. Modern navies that operate such aircraft carriers treat them as capital ships of fleets, a role previously held by the galleons, ships-of-the-line and battleships. This change took place during World War II in response to air power becoming a significant factor in warfare, driven by the superior range, flexibility and effectiveness of carrier-launched aircraft. Following the war, carrier operations continued to increase in size and importance, and along with, carrier designs also increased in size and ability. Some of these larger carriers, dubbed by the media as "supercarriers", displacing 75,000 tons or greater, have become the pinnacle of carrier development. Some are powered by nuclear reactors and form the core of a fleet designed to operate far from home. Amphibious assault ships, such as the and classes, serve the purpose of carrying and landing Marines, and operate a large contingent of helicopters for that purpose. Also known as "commando carriers" or "helicopter carriers", many have the capability to operate VSTOL aircraft. The threatening role of aircraft carriers has a place in modern asymmetric warfare, like the gunboat diplomacy of the past. Carriers also facilitate quick and precise projections of overwhelming military power into such local and regional conflicts. Lacking the firepower of other warships, carriers by themselves are considered vulnerable to attack by other ships, aircraft, submarines, or missiles. Therefore, an aircraft carrier is generally accompanied by a number of other ships to provide protection for the relatively unwieldy carrier, to carry supplies, re-supply (Many carriers are self-sufficient and will supply their escorts) and perform other support services, and to provide additional offensive capabilities. The resulting group of ships is often termed a carrier strike group, battle group, carrier group, or carrier battle group. There is a view among some military pundits that modern anti-ship weapons systems, such as torpedoes and missiles, or even ballistic missiles with nuclear warheads have made aircraft carriers and carrier groups too vulnerable for modern combat. like the German U24 of the conventional 206 class which in 2001 "fired" at the Enterprise during the exercise JTFEX 01-2 in the Caribbean Sea by firing flares and taking a photograph through its periscope or the Swedish Gotland which managed the same feat in 2006 during JTFEX 06-2 by penetrating the defensive measures of Carrier Strike Group 7 which was protecting . Description Structure Carriers are large and long ships, although there is a high degree of variation depending on their intended role and aircraft complement. The size of the carrier has varied over history and among navies, to cater to the various roles that global climates have demanded from naval aviation. Regardless of size, the ship itself must house their complement of aircraft, with space for launching, storing, and maintaining them. Space is also required for the large crew, supplies (food, munitions, fuel, engineering parts), and propulsion. US aircraft carriers are notable for having nuclear reactors powering their systems and propulsion. The top of the carrier is the flight deck, where aircraft are launched and recovered. On the starboard side of this is the island, where the funnel, air-traffic control and the bridge are located. The constraints of constructing a flight deck affect the role of a given carrier strongly, as they influence the weight, type, and configuration of the aircraft that may be launched. For example, assisted launch mechanisms are used primarily for heavy aircraft, especially those loaded with air-to-ground weapons. CATOBAR is most commonly used on US Navy fleet carriers as it allows the deployment of heavy jets with full load-outs, especially on ground-attack missions. STOVL is used by other navies because it is cheaper to operate and still provides good deployment capability for fighter aircraft. Due to the busy nature of the flight deck, only 20 or so aircraft may be on it at any one time. A hangar storage several decks below the flight deck is where most aircraft are kept, and aircraft are taken from the lower storage decks to the flight deck through the use of an elevator. The hangar is usually quite large and can take up several decks of vertical space. Munitions are commonly stored on the lower decks because they are highly explosive. Usually this is below the waterline so that the area can be flooded in case of emergency. Flight deck As "runways at sea", aircraft carriers have a flat-top flight deck, which launches and recovers aircraft. Aircraft launch forward, into the wind, and are recovered from astern. The flight deck is where the most notable differences between a carrier and a land runway are found. Creating such a surface at sea poses constraints on the carrier. For example, the size of the vessel is a fundamental limitation on runway length. This affects take-off procedure, as a shorter runway length of the deck requires that aircraft accelerate more quickly to gain lift. This either requires a thrust boost, a vertical component to its velocity, or a reduced take-off load (to lower mass). The differing types of deck configuration, as above, influence the structure of the flight deck. The form of launch assistance a carrier provides is strongly related to the types of aircraft embarked and the design of the carrier itself. There are two main philosophies in order to keep the deck short: add thrust to the aircraft, such as using a Catapult Assisted Take-Off (CATO-); and changing the direction of the airplanes' thrust, as in Vertical and/or Short Take-Off (V/STO-). Each method has advantages and disadvantages of its own: Catapult assisted take-off but arrested recovery (CATOBAR): A steam- or electric-powered catapult is connected to the aircraft, and is used to accelerate conventional aircraft to a safe flying speed. By the end of the catapult stroke, the aircraft is airborne and further propulsion is provided by its own engines. This is the most expensive method as it requires complex machinery to be installed under the flight deck, but allows for even heavily loaded aircraft to take off. Short take-off but arrested recovery (STOBAR) depends on increasing the net lift on the aircraft. Aircraft do not require catapult assistance for take off; instead on nearly all ships of this type an upwards vector is provided by a ski-jump at the forward end of the flight deck, often combined with thrust vectoring by the aircraft. Alternatively, by reducing the fuel and weapon load, an aircraft is able to reach faster speeds and generate more upwards lift and launch without a ski-jump or catapult. Short take-off vertical-landing (STOVL): On aircraft carriers, non-catapult-assisted, fixed-wing short takeoffs are accomplished with the use of thrust vectoring, which may also be used in conjunction with a runway "ski-jump". Use of STOVL tends to allow aircraft to carry a larger payload as compared to during VTOL use, while still only requiring a short runway. The most famous examples are the Hawker Siddeley Harrier and the BAe Sea Harrier. Although technically VTOL aircraft, they are operationally STOVL aircraft due to the extra weight carried at take-off for fuel and armaments. The same is true of the Lockheed F-35B Lightning II, which demonstrated VTOL capability in test flights but is operationally STOVL or in the case of UK uses "shipborne rolling vertical landing" Vertical take-off and landing (VTOL): Certain aircraft are specifically designed for the purpose of using very high degrees of thrust vectoring (e.g. if the thrust to weight-force ratio is greater than 1, it can take off vertically), but are usually slower than conventionally propelled aircraft due to the additional weight from associated systems. On the recovery side of the flight deck, the adaptation to the aircraft load-out is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-World War II Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck. If the aircraft are VTOL-capable or helicopters, they do not need to decelerate and hence there is no such need. The arrested-recovery system has used an angled deck since the 1950s because, in case the aircraft does not catch the arresting wire, the short deck allows easier take off by reducing the number of objects between the aircraft and the end of the runway. It also has the advantage of separating the recovery operation area from the launch area. Helicopters and aircraft capable of vertical or short take-off and landing (V/STOL) usually recover by coming abreast of the carrier on the port side and then using their hover capability to move over the flight deck and land vertically without the need for arresting gear. Staff and deck operations Carriers steam at speed, up to into the wind during flight deck operations to increase wind speed over the deck to a safe minimum. This increase in effective wind speed provides a higher launch airspeed for aircraft at the end of the catapult stroke or ski-jump, as well as making recovery safer by reducing the difference between the relative speeds of the aircraft and ship. Since the early 1950s on conventional carriers it has been the practice to recover aircraft at an angle to port of the axial line of the ship. The primary function of this angled deck is to allow aircraft that miss the arresting wires, referred to as a bolter, to become airborne again without the risk of hitting aircraft parked forward. The angled deck allows the installation of one or two "waist" catapults in addition to the two bow cats. An angled deck also improves launch and recovery cycle flexibility with the option of simultaneous launching and recovery of aircraft. Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign 'paddles') to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as the optical landing system have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio. Key personnel involved in the flight deck include the shooters, the handler, and the air boss. Shooters are naval aviators or naval flight officers and are responsible for launching aircraft. The handler works just inside the island from the flight deck and is responsible for the movement of aircraft before launching and after recovery. The "air boss" (usually a commander) occupies the top bridge (Primary Flight Control, also called primary or the tower) and has the overall responsibility for controlling launch, recovery and "those aircraft in the air near the ship, and the movement of planes on the flight deck, which itself resembles a well-choreographed ballet". The captain of the ship spends most of his time one level below primary on the Navigation Bridge. Below this is the Flag Bridge, designated for the embarked admiral and his staff. To facilitate working on the flight deck of a US aircraft carrier, the sailors wear colored shirts that designate their responsibilities. There are at least seven different colors worn by flight deck personnel for modern United States Navy carrier air operations. Carrier operations of other nations use similar color schemes. Deck structures The superstructure of a carrier (such as the bridge, flight control tower) are concentrated in a relatively small area called an island, a feature pioneered on in 1923. While the island is usually built on the starboard side of the flight deck, the Japanese aircraft carriers and had their islands built on the port side. Very few carriers have been designed or built without an island. The flush deck configuration proved to have significant drawbacks, primary of which was management of the exhaust from the power plant. Fumes coming across the deck were a major issue in . In addition, lack of an island meant difficulties managing the flight deck, performing air traffic control, a lack of radar housing placements and problems with navigating and controlling the ship itself. Another deck structure that can be seen is a ski-jump ramp at the forward end of the flight deck. This was first developed to help launch short take off vertical landing (STOVL) aircraft take off at far higher weights than is possible with a vertical or rolling takeoff on flat decks. Originally developed by the Royal Navy, it since has been adopted by many navies for smaller carriers. A ski-jump ramp works by converting some of the forward rolling movement of the aircraft into vertical velocity and is sometimes combined with the aiming of jet thrust partly downwards. This allows heavily loaded and fueled aircraft a few more precious seconds to attain sufficient air velocity and lift to sustain normal flight. Without a ski-jump, launching fully-loaded and fueled aircraft such as the Harrier would not be possible on a smaller flat deck ship before either stalling out or crashing directly into the sea. Although STOVL aircraft are capable of taking off vertically from a spot on the deck, using the ramp and a running start is far more fuel efficient and permits a heavier launch weight. As catapults are unnecessary, carriers with this arrangement reduce weight, complexity, and space needed for complex steam or electromagnetic launching equipment. Vertical landing aircraft also remove the need for arresting cables and related hardware. Russian, Chinese, and Indian carriers include a ski-jump ramp for launching lightly loaded conventional fighter aircraft but recover using traditional carrier arresting cables and a tailhook on their aircraft. The disadvantage of the ski-jump is the penalty it exacts on aircraft size, payload, and fuel load (and thus range); heavily laden aircraft cannot launch using a ski-jump because their high loaded weight requires either a longer takeoff roll than is possible on a carrier deck, or assistance from a catapult or JATO rocket. For example, the Russian Sukhoi Su-33 is only able to launch from the carrier with a minimal armament and fuel load. Another disadvantage is on mixed flight deck operations where helicopters are also present, such as on a US landing helicopter dock or landing helicopter assault amphibious assault ship. A ski jump is not included as this would eliminate one or more helicopter landing areas; this flat deck limits the loading of Harriers but is somewhat mitigated by the longer rolling start provided by a long flight deck compared to many STOVL carriers. National fleets The US Navy has the largest fleet of carriers in the world, with eleven supercarriers currently in service. China and India each have two STOBAR carriers in service. The UK has two STOVL carriers in service. The navies of France and Russia each operate a single medium-sized carrier. The US also has nine similarly sized Amphibious Warfare Ships. There are five small light carriers in use capable of operating both fixed-wing aircraft and helicopters; Japan and Italy each operate two, and Spain one. Additionally there are eighteen small carriers which only operate helicopters serving the navies of Australia (2), Brazil (1), China (2), Egypt (2), France (3), Japan (4), South Korea (2), Thailand (1) and Turkey (1). Algeria Current Kalaat Béni Abbès (L-474) is an amphibious transport dock of the Algerian National Navy with two deck-landing spots for helicopters. Australia Current The Royal Australian Navy operates two s. The two-ship class, based on the Spanish vessel and built by Navantia and BAE Systems Australia, represents the largest ships ever built for the Royal Australian Navy. underwent sea trials in late 2013 and was commissioned in 2014. Her sister ship, , was commissioned in December 2015. The Australian ships retain the ski-ramp from the Juan Carlos I design, although the RAN has not acquired carrier-based fixed-wing aircraft. Brazil Current In December 2017, the Brazilian Navy confirmed the purchase of for (GBP) £84.6 million (equivalent to R$359.5M and US$113.2M) and renamed her . The ship was decommissioned from Royal Navy service in March 2018. The Brazilian Navy commissioned the carrier on 29 June 2018 in the United Kingdom. After undertaking a period of maintenance in the UK, the ship travelled to its new home port, Arsenal de Marinha do Rio de Janeiro (AMRJ) in order to be fully operational by 2020. The ship displaces 21,578 tonnes, is long and has a range of . Before leaving HMNB Devonport for her new homeport in Rio's AMRJ, Atlântico underwent operational sea training under the Royal Navy's Flag Officer Sea Training (FOST) program. On 12 November 2020, Atlântico was redesignated "NAM", for "multipurpose aircraft carrier" (), from "PHM", for "multipurpose helicopter carrier" (), to reflect the ship's capability to operate with fixed-wing medium-altitude long-endurance unmanned aerial vehicles as well as crewed tiltrotor VTOL aircraft. China Current 2 STOBAR carriers: (60,900 tons) was originally built as the Soviet carrier Varyag and was later purchased as a hulk in 1998 on the pretext of use as a floating casino, then towed to China for rebuild and completion. Liaoning was commissioned on 25 September 2012 and began service for testing and training. In November 2012, Liaoning launched and recovered Shenyang J-15 naval fighter aircraft for the first time. After a refit in January 2019, she was assigned to the North Sea Fleet, a change from her previous role as a training carrier. (60,000–70,000 tons) was launched on 26 April 2017. She is the first to be built domestically, to an improved Kuznetsov-class design. Shandong started sea trials on 23 April 2018, and entered service in December 2019. 1 CATOBAR carrier: (80,000 tons) is a CATOBAR carrier which was under construction between 2015 and 2016 before being completed in June 2022. She is being fitted out as of 2022 and will commence service in 2023–2024. 3 Landing helicopter docks A Type 075 LHD, was commissioned on 23 April 2021 at the naval base in Sanya. A second ship, Guangxi, was commissioned on 26 December 2021 and a third ship, Anhui, was commissioned in October 2022. Future China has had a long-term plan to operate six large aircraft carriers with two carriers per fleet. China is planning a class of eight landing helicopter dock vessels, the Type 075 (NATO reporting name Yushen-class landing helicopter assault). This is a class of amphibious assault ship under construction by the Hudong–Zhonghua Shipbuilding company. The first ship was commissioned in April 2021. China is also planning a modified class of the same concept, the Type 076 landing helicopter dock, that will also be equipped with an electromagnetic catapult launch system. Egypt Current Egypt signed a contract with French shipbuilder DCNS to buy two helicopter carriers for approximately 950 million euros. The two ships were originally to be sold to Russia, but the deal was cancelled by France due to the Russian invasion of Ukraine. On 2 June 2016, Egypt received the first of two helicopter carriers acquired in October 2015, the landing helicopter dock . The flag transfer ceremony took place in the presence of Egyptian and French Navies' chiefs of staff, chairman and chief executive officers of both DCNS and STX France, and senior Egyptian and French officials. On 16 September 2016, DCNS delivered the second of two helicopter carriers, the landing helicopter dock which also participated in a joint military exercise with the French Navy before arriving at her home port of Alexandria. Egypt is so far the only country in Africa or the Middle East to possess a helicopter carrier. France Current The French Navy operates the 42,000-tonne nuclear-powered aircraft carrier, . Commissioned in 2001, she is the flagship of the French Navy. The ship carries a complement of Dassault Rafale M and E-2C Hawkeye aircraft, EC725 Caracal and AS532 Cougar helicopters for combat search and rescue, as well as modern electronics and Aster missiles. She is a CATOBAR-type carrier that uses two 75 m C13-3 steam catapults of a shorter version of the catapult system installed on the US carriers, one catapult at the bow and one across the front of the landing area. In addition, the French Navy operates three s. Future In October 2018, the French Ministry of Defence began an 18-month study for €40 million for the eventual future replacement of the beyond 2030. In December 2020, President Macron announced that construction of the next generation carrier would begin in around 2025 with sea trials to start in about 2036. The carrier is planned to have a displacement of around 75,000 tons and to carry about 32 next-generation fighters, two to three E-2D Advanced Hawkeyes and a yet-to-be-determined number of unmanned carrier air vehicles. India Current 2 STOBAR carriers: , 45,400 tonnes, modified Kiev class. The carrier was purchased by India on 20 January 2004 after years of negotiations at a final price of $2.35 billion (). The ship successfully completed her sea trials in July 2013 and aviation trials in September 2013. She was formally commissioned on 16 November 2013 at a ceremony held at Severodvinsk, Russia. , also known as Indigenous Aircraft Carrier 1 (IAC-1) a 45,000-tonne, aircraft carrier whose keel was laid in 2009. The new carrier will operate MiG-29K and naval HAL Tejas aircraft. The ship is powered by gas-turbines and has a range of and deploys 10 helicopters and 30 aircraft. The ship was launched in 2013, sea-trials began in August 2021 and was commissioned on 02 September 2022. Future India has plans for a third carrier, , also known as Indigenous Aircraft Carrier 2 (IAC-2) with a displacement of over 65,000 tonnes and is planned with a CATOBAR system to launch and recover heavier aircraft. India has also issued a request for information (RFI) to procure four Landing helicopter dock displacing 30,000-40,000 tons with a capacity to operate 12 medium lift special ops and two heavy lift helicopters and troops for amphibious operations. Italy Current 2 STOVL carriers: : 14,000-tonne Italian STOVL carrier, commissioned in 1985. : 30000-tonne Italian STOVL carrier designed and built with secondary amphibious assault facilities, commissioned in 2008. Future Italy plans to replace ageing aircraft carrier Giuseppe Garibaldi, as well as one of the landing helicopter docks, with a new amphibious assault ship, to be named . The ship will be significantly larger than her predecessors with a displacement of 38,000 tonnes at full load. Trieste is to carry the F-35B Joint Strike Fighter. Meanwhile, Giuseppe Garibaldi will be transferred to Italian Space Operation Command for use as a satellite launch platform. Japan Current 2 s – , 19,500-tonne (27,000 tonnes full load) STOVL carrier Izumo was launched August 2013 and commissioned March 2015. Izumos sister ship, Kaga, was commissioned in 2017. In December 2018, the Japanese Cabinet gave approval to convert both Izumo-class destroyers into aircraft carriers for F-35B STOVL operations. The conversion of Izumo was underway as of mid-2020. The modification of maritime escort vessels is to "increase operational flexibility" and enhance Pacific air defense, the Japanese defense ministry's position is "We are not creating carrier air wings or carrier air squadrons" similar to the US Navy. The Japanese STOVL F-35s, when delivered, will be operated by the Japan Air Self Defense Force from land bases; according to the 2020 Japanese Defense Ministry white paper the STOVL model was chosen for the JASDF due the lack of appropriately long runways to support air superiority capability across all of Japanese airspace. Japan has requested that the USMC deploy STOVL F-35s and crews aboard the Izumo-class ships "for cooperation and advice on how to operate the fighter on the deck of the modified ships". On 3 October 2021, two USMC F-35Bs performed the first vertical landings and horizontal take-offs from JS Izumo, marking 75 years since fixed-wing aircraft operated from a Japanese carrier. 2 s – 19,000-tonne (full load) anti-submarine warfare carriers with enhanced command-and-control capabilities allowing them to serve as fleet flagships. Russia Current 1 STOBAR carrier: Admiral Flota Sovetskogo Soyuza Kuznetsov: 55,000-tonne STOBAR aircraft carrier. Launched in 1985 as Tbilisi, renamed and operational from 1995. Without catapults she can launch and recover lightly fueled naval fighters for air defense or anti-ship missions but not heavy conventional bombing strikes. Officially designated an aircraft carrying cruiser, she is unique in carrying a heavy cruiser's complement of defensive weapons and large P-700 Granit offensive missiles. The P-700 systems will be removed in the coming refit to enlarge her below decks aviation facilities as well as upgrading her defensive systems. Future The Russian Government has been considering the potential replacement of Admiral Kuznetsov for some time and has considered the Shtorm-class aircraft carrier as a possible option. This carrier will be a hybrid of CATOBAR and STOBAR, given the fact that she utilizes both systems of launching aircraft. The carrier is expected to cost As of 2020, the project had not yet been approved and, given the financial costs, it was unclear whether it would be made a priority over other elements of Russian naval modernization. A class of 2 LHD, Project 23900 is planned and an official keel laying ceremony for the project happened on 20 July 2020. South Korea Current Two 18,860-tonne full deck amphibious assault ships with hospital and well deck and facilities to serve as fleet flagships. Future South Korea has set tentative plans for procuring two light aircraft carriers by 2033, which would help make the ROKN a blue water navy. In December 2020, details of South Korea's planned carrier program (CVX) were finalized. A vessel of about 40,000 tons is envisaged carrying about 20 F-35B fighters as well as future maritime attack helicopters. Service entry had been anticipated in the early 2030s. The program has encountered opposition in the National Assembly. In November 2021, the National Defense Committee of the National Assembly reduced the program's requested budget of 7.2 billion KRW and to just 500 million KRW (about $400K USD), effectively putting the project on hold, at least temporarily. However, on 3 December 2021 the full budget of 7.2 billion won was passed by the National Assembly. Basic design work is to begin in earnest starting 2022. Spain Current : 27,000-tonne, specially designed multipurpose strategic projection ship which can operate as an amphibious assault ship and aircraft carrier. Juan Carlos I has full facilities for both functions including a ski jump for STOVL operations, is equipped with the AV-8B Harrier II attack aircraft. Also, well deck, and vehicle storage area which can be used as additional hangar space, launched in 2008, commissioned 30 September 2010. Thailand Current 1 offshore helicopter support ship: helicopter carrier: 11,400-tonne STOVL carrier based on Spanish design. Commissioned in 1997. The AV-8S Matador/Harrier STOVL fighter wing, mostly inoperable by 1999, was retired from service without replacement in 2006. As of 2010, the ship is used for helicopter operations and for disaster relief. Turkey Current is a 27,079-tonne amphibious assault ship (LHD) of the Turkish Navy that can be configured as a 24,660-tonne V/STOL aircraft carrier. Construction began on 30 April 2016 by Sedef Shipbuilding Inc. at their Istanbul shipyard. TCG Anadolu was commissioned with a ceremony on April 10, 2023. The construction of a sister ship, to be named TCG Trakya, is currently being planned by the Turkish Navy. The Baykar Kızılelma, a newly designed, jet-engined UCAV developed for the Turkish Navy and Turkish Air Force as part of Project MIUS, will operate from TCG Anadolu. Its maiden flight was successfully completed on December 14, 2022. The runway tests of TAI Anka-3, another jet-engined UCAV of Project MIUS (with a flying wing design and stealth technology), began in April 2023. Its maiden flight is scheduled for May 2023. United Kingdom Current Two 65,000-tonne Queen Elizabeth-class STOVL carriers which operate the F-35 Lightning II. was commissioned in December 2017 and in December 2019. Queen Elizabeth undertook her first operational deployment in 2021. Each Queen Elizabeth-class ship is able to operate around 40 aircraft during peacetime operations and is thought to be able to carry up to 72 at maximum capacity. As of the end of April 2020, 18 F-35B aircraft had been delivered to the Royal Navy and the Royal Air Force. "Full operating capability" for the UK's carrier strike capability had been planned for 2023 (2 squadrons or 24 jets operating from one carrier). The longer-term aim remains for the ability to conduct a wide range of air operations and support amphibious operations worldwide from both carriers by 2026. They form the central part of the UK Carrier Strike Group. Future The Queen Elizabeth-class ships are expected to have service lives of 50 years. United States Current 11 CATOBAR carriers, all nuclear-powered: : ten 101,000-tonne, fleet carriers, the first of which was commissioned in 1975. A Nimitz-class carrier is powered by two nuclear reactors providing steam to four steam turbines. , one 100,000-tonne, fleet carrier. The lead of the class came into service in 2017, with another nine planned to replace the aging Nimitz-class ships. Nine amphibious assault ships carrying vehicles, Marine fighters, attack and transport helicopters, and landing craft with STOVL fighters for CAS and CAP: : a class of 45,000-tonne amphibious assault ships, although the first two ships in this class, (Flight 0) do not have a well decks, all subsequent ships (Flight I) will have well decks. Two ships are currently in service out of a planned 11 ships. Ships of this class can have a secondary mission as a light aircraft carrier with 20 AV-8B Harrier II, and in the future the F-35B Lightning II aircraft after unloading their Marine expeditionary unit. : a class of 41,000-tonne amphibious assault ships, members of this class have been used in wartime in their secondary mission as light carriers with 20 to 25 AV-8Bs after unloading their Marine expeditionary unit. Seven ship currently in service of an original eight, with one lost to fire. Future The current US fleet of Nimitz-class carriers will be followed into service (and in some cases replaced) by the . It is expected that the ships will be more automated in an effort to reduce the amount of funding required to maintain and operate the vessels. The main new features are implementation of Electromagnetic Aircraft Launch System (EMALS) (which replaces the old steam catapults) and unmanned aerial vehicles. In terms of future carrier developments, Congress has discussed the possibility of accelerating the phasing-out of one or more Nimitz-class carriers, postponing or canceling the procurement of CVN-81 and CVN-82, or modifying the purchase contract. Following the deactivation of in December 2012, the US fleet comprised 10 fleet carriers, but that number increased back to 11 with the commissioning of Gerald R. Ford in July 2017. The House Armed Services Seapower subcommittee on 24 July 2007, recommended seven or eight new carriers (one every four years). However, the debate has deepened over budgeting for the $12–14.5 billion (plus $12 billion for development and research) for the 100,000-tonne Gerald R. Ford-class carrier (estimated service 2017) compared to the smaller $2 billion 45,000-tonne s, which are able to deploy squadrons of F-35Bs. The first of this class, , is now in active service with another, , and 9 more are planned. In a report to Congress in February 2018, the Navy stated it intends to maintain a "12 CVN force" as part of its 30-year acquisition plan. Aircraft carriers in preservation Current museum carriers A few aircraft carriers have been preserved as museum ships. They are: in Mount Pleasant, South Carolina in New York City in Alameda, California in Corpus Christi, Texas in San Diego, California in Tianjin, China in Nantong, China Former museum carriers was moored as a museum in Mumbai from 2001 to 2012, but was never able to find an industrial partner and was closed that year. She was scrapped in 2014. was acquired for preservation and moored in New Orleans from 1990 to 2002, but due to an embezzlement scandal, funding for the museum never materialized and the ship was scrapped in 2002. Future museum carriers has a preservation campaign to bring her to the West Coast of the United States as the world's first amphibious assault ship museum.

In computer science, the analysis of algorithms is the process of finding the computational complexity of algorithms—the amount of time, storage, or other resources needed to execute them. Usually, this involves determining a function that relates the size of an algorithm's input to the number of steps it takes (its time complexity) or the number of storage locations it uses (its space complexity). An algorithm is said to be efficient when this function's values are small, or grow slowly compared to a growth in the size of the input. Different inputs of the same size may cause the algorithm to have different behavior, so best, worst and average case descriptions might all be of practical interest. When not otherwise specified, the function describing the performance of an algorithm is usually an upper bound, determined from the worst case inputs to the algorithm. The term "analysis of algorithms" was coined by Donald Knuth. Algorithm analysis is an important part of a broader computational complexity theory, which provides theoretical estimates for the resources needed by any algorithm which solves a given computational problem. These estimates provide an insight into reasonable directions of search for efficient algorithms. In theoretical analysis of algorithms it is common to estimate their complexity in the asymptotic sense, i.e., to estimate the complexity function for arbitrarily large input. Big O notation, Big-omega notation and Big-theta notation are used to this end. For instance, binary search is said to run in a number of steps proportional to the logarithm of the size of the sorted list being searched, or in , colloquially "in logarithmic time". Usually asymptotic estimates are used because different implementations of the same algorithm may differ in efficiency. However the efficiencies of any two "reasonable" implementations of a given algorithm are related by a constant multiplicative factor called a hidden constant. Exact (not asymptotic) measures of efficiency can sometimes be computed but they usually require certain assumptions concerning the particular implementation of the algorithm, called model of computation. A model of computation may be defined in terms of an abstract computer, e.g. Turing machine, and/or by postulating that certain operations are executed in unit time. For example, if the sorted list to which we apply binary search has elements, and we can guarantee that each lookup of an element in the list can be done in unit time, then at most time units are needed to return an answer. Cost models Time efficiency estimates depend on what we define to be a step. For the analysis to correspond usefully to the actual run-time, the time required to perform a step must be guaranteed to be bounded above by a constant. One must be careful here; for instance, some analyses count an addition of two numbers as one step. This assumption may not be warranted in certain contexts. For example, if the numbers involved in a computation may be arbitrarily large, the time required by a single addition can no longer be assumed to be constant. Two cost models are generally used: the uniform cost model, also called unit-cost model (and similar variations), assigns a constant cost to every machine operation, regardless of the size of the numbers involved the logarithmic cost model, also called logarithmic-cost measurement (and similar variations), assigns a cost to every machine operation proportional to the number of bits involved The latter is more cumbersome to use, so it's only employed when necessary, for example in the analysis of arbitrary-precision arithmetic algorithms, like those used in cryptography. A key point which is often overlooked is that published lower bounds for problems are often given for a model of computation that is more restricted than the set of operations that you could use in practice and therefore there are algorithms that are faster than what would naively be thought possible. Run-time analysis Run-time analysis is a theoretical classification that estimates and anticipates the increase in running time (or run-time or execution time) of an algorithm as its input size (usually denoted as ) increases. Run-time efficiency is a topic of great interest in computer science: A program can take seconds, hours, or even years to finish executing, depending on which algorithm it implements. While software profiling techniques can be used to measure an algorithm's run-time in practice, they cannot provide timing data for all infinitely many possible inputs; the latter can only be achieved by the theoretical methods of run-time analysis. Shortcomings of empirical metrics Since algorithms are platform-independent (i.e. a given algorithm can be implemented in an arbitrary programming language on an arbitrary computer running an arbitrary operating system), there are additional significant drawbacks to using an empirical approach to gauge the comparative performance of a given set of algorithms. Take as an example a program that looks up a specific entry in a sorted list of size n. Suppose this program were implemented on Computer A, a state-of-the-art machine, using a linear search algorithm, and on Computer B, a much slower machine, using a binary search algorithm. Benchmark testing on the two computers running their respective programs might look something like the following: Based on these metrics, it would be easy to jump to the conclusion that Computer A is running an algorithm that is far superior in efficiency to that of Computer B. However, if the size of the input-list is increased to a sufficient number, that conclusion is dramatically demonstrated to be in error: Computer A, running the linear search program, exhibits a linear growth rate. The program's run-time is directly proportional to its input size. Doubling the input size doubles the run-time, quadrupling the input size quadruples the run-time, and so forth. On the other hand, Computer B, running the binary search program, exhibits a logarithmic growth rate. Quadrupling the input size only increases the run-time by a constant amount (in this example, 50,000 ns). Even though Computer A is ostensibly a faster machine, Computer B will inevitably surpass Computer A in run-time because it's running an algorithm with a much slower growth rate. Orders of growth Informally, an algorithm can be said to exhibit a growth rate on the order of a mathematical function if beyond a certain input size , the function times a positive constant provides an upper bound or limit for the run-time of that algorithm. In other words, for a given input size greater than some 0 and a constant , the run-time of that algorithm will never be larger than . This concept is frequently expressed using Big O notation. For example, since the run-time of insertion sort grows quadratically as its input size increases, insertion sort can be said to be of order . Big O notation is a convenient way to express the worst-case scenario for a given algorithm, although it can also be used to express the average-case — for example, the worst-case scenario for quicksort is , but the average-case run-time is . Empirical orders of growth Assuming the run-time follows power rule, , the coefficient can be found by taking empirical measurements of run-time } at some problem-size points }, and calculating so that . In other words, this measures the slope of the empirical line on the log–log plot of run-time vs. input size, at some size point. If the order of growth indeed follows the power rule (and so the line on the log–log plot is indeed a straight line), the empirical value of will stay constant at different ranges, and if not, it will change (and the line is a curved line)—but still could serve for comparison of any two given algorithms as to their empirical local orders of growth behaviour. Applied to the above table: It is clearly seen that the first algorithm exhibits a linear order of growth indeed following the power rule. The empirical values for the second one are diminishing rapidly, suggesting it follows another rule of growth and in any case has much lower local orders of growth (and improving further still), empirically, than the first one. Evaluating run-time complexity The run-time complexity for the worst-case scenario of a given algorithm can sometimes be evaluated by examining the structure of the algorithm and making some simplifying assumptions. Consider the following pseudocode: 1 get a positive integer n from input 2 if n > 10 3 print "This might take a while..." 4 for i = 1 to n 5 for j = 1 to i 6 print i * j 7 print "Done!" A given computer will take a discrete amount of time to execute each of the instructions involved with carrying out this algorithm. Say that the actions carried out in step 1 are considered to consume time at most T1, step 2 uses time at most T2, and so forth. In the algorithm above, steps 1, 2 and 7 will only be run once. For a worst-case evaluation, it should be assumed that step 3 will be run as well. Thus the total amount of time to run steps 1-3 and step 7 is: The loops in steps 4, 5 and 6 are trickier to evaluate. The outer loop test in step 4 will execute ( n + 1 ) times, which will consume T4( n + 1 ) time. The inner loop, on the other hand, is governed by the value of j, which iterates from 1 to i. On the first pass through the outer loop, j iterates from 1 to 1: The inner loop makes one pass, so running the inner loop body (step 6) consumes T6 time, and the inner loop test (step 5) consumes 2T5 time. During the next pass through the outer loop, j iterates from 1 to 2: the inner loop makes two passes, so running the inner loop body (step 6) consumes 2T6 time, and the inner loop test (step 5) consumes 3T5 time. Altogether, the total time required to run the inner loop body can be expressed as an arithmetic progression: which can be factored as The total time required to run the inner loop test can be evaluated similarly: which can be factored as Therefore, the total run-time for this algorithm is: which reduces to As a rule-of-thumb, one can assume that the highest-order term in any given function dominates its rate of growth and thus defines its run-time order. In this example, n2 is the highest-order term, so one can conclude that . Formally this can be proven as follows: A more elegant approach to analyzing this algorithm would be to declare that [T1..T7] are all equal to one unit of time, in a system of units chosen so that one unit is greater than or equal to the actual times for these steps. This would mean that the algorithm's run-time breaks down as follows: Growth rate analysis of other resources The methodology of run-time analysis can also be utilized for predicting other growth rates, such as consumption of memory space. As an example, consider the following pseudocode which manages and reallocates memory usage by a program based on the size of a file which that program manages: while file is still open: let n = size of file for every 100,000 kilobytes of increase in file size double the amount of memory reserved In this instance, as the file size n increases, memory will be consumed at an exponential growth rate, which is order . This is an extremely rapid and most likely unmanageable growth rate for consumption of memory resources. Relevance Algorithm analysis is important in practice because the accidental or unintentional use of an inefficient algorithm can significantly impact system performance. In time-sensitive applications, an algorithm taking too long to run can render its results outdated or useless. An inefficient algorithm can also end up requiring an uneconomical amount of computing power or storage in order to run, again rendering it practically useless. Constant factors Analysis of algorithms typically focuses on the asymptotic performance, particularly at the elementary level, but in practical applications constant factors are important, and real-world data is in practice always limited in size. The limit is typically the size of addressable memory, so on 32-bit machines 232 = 4 GiB (greater if segmented memory is used) and on 64-bit machines 264 = 16 EiB. Thus given a limited size, an order of growth (time or space) can be replaced by a constant factor, and in this sense all practical algorithms are for a large enough constant, or for small enough data. This interpretation is primarily useful for functions that grow extremely slowly: (binary) iterated logarithm (log*) is less than 5 for all practical data (265536 bits); (binary) log-log (log log n) is less than 6 for virtually all practical data (264 bits); and binary log (log n) is less than 64 for virtually all practical data (264 bits). An algorithm with non-constant complexity may nonetheless be more efficient than an algorithm with constant complexity on practical data if the overhead of the constant time algorithm results in a larger constant factor, e.g., one may have so long as and . For large data linear or quadratic factors cannot be ignored, but for small data an asymptotically inefficient algorithm may be more efficient. This is particularly used in hybrid algorithms, like Timsort, which use an asymptotically efficient algorithm (here merge sort, with time complexity ), but switch to an asymptotically inefficient algorithm (here insertion sort, with time complexity ) for small data, as the simpler algorithm is faster on small data.

Atari () is a brand name that has been owned by several entities since its inception in 1972. It is currently owned by French company Atari SA (formerly Infogrames) through a subsidiary named Atari Interactive. The original Atari, Inc., founded in Sunnyvale, California, USA in 1972 by Nolan Bushnell and Ted Dabney, was a pioneer in arcade games, home video game consoles, and home computers. The company's products, such as Pong and the Atari 2600, helped define the electronic entertainment industry from the 1970s to the mid-1980s. In 1984, as a result of the video game crash of 1983, the home console and computer divisions of the original Atari Inc. were sold off to Jack Tramiel's Tramel Technology Ltd., which then renamed itself to Atari Corporation. Atari, Inc. was renamed Atari Games Inc. Atari Games received the rights to use the logo and brand name with appended text "Games" on arcade games. The rights to Atari, Inc.'s game properties were shared between the two companies, with Atari Corporation receiving the trademarks and the home rights. In 1996, Atari Corporation reverse-merged with disk-drive manufacturer JT Storage (JTS), becoming a division within the company. In 1998, Hasbro Interactive acquired all Atari Corporation–related properties from JTS, creating a new subsidiary, Atari Interactive. Infogrames Entertainment (IESA) bought Hasbro Interactive in 2001 and renamed it Infogrames Interactive, which intermittently published Atari-branded titles. In 2003, it renamed the division Atari Interactive. Another IESA division, Infogrames Inc., changed its name to Atari, Inc. the same year, licensing the Atari name and logo from its fellow subsidiary. In 2008, IESA completed its acquisition of Atari, Inc.'s outstanding stock, making it a wholly owned subsidiary. IESA renamed itself Atari SA in 2009. It sought bankruptcy protection under French law in January 2013. As of 2023, the current Atari's focus is on "video games, consumer hardware, licensing and blockchain". History Logotype The name comes from the Japanese term atari, used while playing the ancient board game Go. The word atari means "to hit a target" in Japanese and is associated with good fortune; in Go, it indicates a situation where a player will be able to capture one or more stones of the opponent in the next move. The Atari logo was designed by George Opperman, who was Atari's first in-house graphic designer and drawn by Evelyn Seto. The design is known as "Fuji" for its resemblance to the Japanese mountain, although the logo's origins are unrelated to it. Opperman designed the logo intending for the silhouette to look like the letter A as in Atari and for its three "prongs" to resemble players and the midline of the "court" in the company's first hit game, Pong. Atari Inc. (1972–1984) In 1971, Nolan Bushnell and Ted Dabney founded a small engineering company, Syzygy Engineering, that designed Computer Space, the world's first commercially available arcade video game, for Nutting Associates. On June 27, 1972, the two incorporated Atari, Inc. and soon hired Al Alcorn as their first design engineer. Bushnell asked Alcorn to produce an arcade version of the Magnavox Odyssey's Tennis game, which would be named Pong. While Bushnell incorporated Atari in June 1972, Syzygy Company was never formally incorporated. Before Atari's incorporation, Bushnell considered various terms from the game Go, eventually choosing atari, referencing a position in the game when a group of stones is imminently in danger of being taken by one's opponent. Atari was incorporated in the state of California on June 27, 1972. In 1973, Atari secretly spawned a competitor called Kee Games, headed by Nolan's next-door neighbor Joe Keenan, to circumvent pinball distributors' insistence on exclusive distribution deals; both Atari and Kee could market nearly the same game to different distributors, each getting an "exclusive" deal. Joe Keenan's management of the subsidiary led to his appointment as president of Atari when Kee was absorbed into the company in 1974. In 1975, Atari's Grass Valley, California subsidiary Cyan Engineering started the development of a flexible console that was capable of playing the four existing Atari games. The result was the Atari Video Computer System, or VCS (later renamed 2600 when the 5200 was released). The introductory price of $199 () included a console, two joysticks, a pair of paddles, and the Combat game cartridge. Bushnell knew he had another potential hit on his hands but bringing the machine to market would be extremely expensive. Looking for outside investors, Bushnell sold Atari to Warner Communications in 1976 for $28 million. Nolan continued to have disagreements with Warner Management over the direction of the company, the discontinuation of the pinball division, and most importantly, the notion of discontinuing the 2600. In 1978, Kee Games was disbanded. In December of that year, Bushnell was fired following an argument with Manny Gerard. "[W]e started fighting like cats and dogs. And then the wheels came off that fall. Warner claimed they fired me", recalled Bushnell. "I say I quit. It was a mutual separation." The development of a successor to the 2600 started as soon as it shipped. The original team estimated the 2600 had a lifespan of about three years; it then set forth to build the most powerful machine possible within that time frame. Mid-way into their effort the home computer revolution took off, leading to the addition of a keyboard and features to produce the Atari 800 and its smaller sibling, the 400. The new machines had some success when they finally became available in quantity in 1980. From this platform Atari released their next-generation game console in 1982, the Atari 5200. It was unsuccessful due to incompatibility with the 2600 game library, a small quantity of dedicated games, and notoriously unreliable controllers. Porting arcade games to home systems with inferior hardware was difficult. The ported version of Pac-Man for Atari 2600 omitted many of the visual features of the original to compensate for the lack of ROM space and the hardware struggled when multiple ghosts appeared on the screen creating a flickering effect. Under Warner and Atari's chairman and CEO, Raymond Kassar, the company achieved its greatest success, selling millions of 2600s and computers. At its peak, Atari accounted for a third of Warner's annual income and was the fastest-growing company in US history at the time. It ran into problems in the early 1980s. Faced with fierce competition and price wars in the game console and home computer markets, Atari was never able to duplicate the success of the 2600. These problems were followed by the video game crash of 1983, with losses that totaled more than $500 million. Warner's stock price slid from $60 to $20, and the company began searching for a buyer for its troubled division. In 1983, Ray Kassar resigned. Financial problems continued to mount and Kassar's successor, James J. Morgan, had less than a year in which to tackle the company's problems. He began a massive restructuring of the company and worked with Warner Communications in May 1984 to create "NATCO" (an acronym for New Atari Company). NATCO further streamlined the company's facilities, personnel, and spending. Unknown to James Morgan and the senior management of Atari, Warner had been in talks with Tramel Technology to buy Atari's consumer electronics and home computer divisions. Negotiating until close to midnight on July 1, 1984, Jack Tramiel purchased the home computing and game console divisions of Atari for $240 million in promissory notes and stocks. Warner gained a 20% stake in Tramel Technologies, which was renamed Atari Corporation. Warner retained the arcade division, continuing it under the name Atari Games, but sold it to Namco in 1985. Warner also sold the Ataritel division to Mitsubishi. Atari Corporation (1984–1996) Under Tramiel's ownership, Atari Corp. used the remaining stock of game console inventory to keep the company afloat while they finished development on a 16/32-bit computer system, the Atari ST. ("ST" stands for "sixteen/thirty-two", referring to the machines' 16-bit bus and 32-bit processor core.) In April 1985, they released an update to the 8-bit computer line, the Atari 65XE, the first in the Atari XE series. June 1985 saw the release of the Atari 130XE; Atari User Groups received early sneak-preview samples of the new Atari 520ST's, and major retailer shipments hit store shelves in September 1985 of Atari's new 32-bit Atari ST computers. In 1986, Atari launched two consoles designed under Warner — the Atari 2600jr and the Atari 7800 console (which saw limited release in 1984). Atari rebounded, earning a $25 million profit that year. In 1987, Atari acquired the Federated Group for $67.3 million, securing shelf space in over 60 stores in California, Arizona, Texas and Kansas at a time when major American electronics outlets were reluctant to carry Atari-branded computers, and two-thirds of Atari's PC production was sold in Europe. The Federated Group (not related to Federated Department Stores) was sold to Silo in 1989. In 1988, the company unveiled the 1040STF and the Mega ST with a bit image manipulator chip, and launched its first parallel computer. The ATW-800 Transputer was based on the Inmos T800 CPU, which had a 32/64-bit architecture, ran at 15 million instructions per second (MIPS) and housed a Charity videochip that supported 16 million colors. The company continued to experiment with parallel computing aiming at B2B customers and graphic designers, but the transputer line failed to achieve commercial success. In 1989, Atari released the Atari Lynx, a handheld console with color graphics, to much fanfare. A shortage of parts kept the system from being released nationwide for the 1989 Christmas season, and the Lynx lost market share to Nintendo's Game Boy, which, despite only having a black and white display, was cheaper, had better battery life and had much higher availability. Tramiel emphasized computers over game consoles but Atari's proprietary computer architecture and operating system fell victim to the success of the Wintel platform while the game market revived. In 1989, Atari Corp. sued Nintendo for $250 million, alleging it had an illegal monopoly. Atari eventually lost the case when it was rejected by a US district court in 1992. In 1991, Atari released its PCs ABC386SXII and ABC386DXII based on Intel's i386 chip. In 1993, Atari positioned its Jaguar as the only 64-bit interactive media entertainment system available, but it sold poorly. It would be the last home console to be produced by Atari and the last to be produced by an American manufacturer until Microsoft's introduction of the Xbox in 2001. By 1996, a series of successful lawsuits had left Atari with millions of dollars in the bank, but the failure of the Lynx and Jaguar left Atari without a product to sell. Tramiel and his family also wanted out of the business. The result was a rapid succession of changes in ownership. In July 1996, Atari merged with JTS Inc., a short-lived maker of hard disk drives, to form JTS Corp. Atari's role in the new company largely became that of holder for the Atari properties and minor support, and consequently the name largely disappeared from the market. Atari Games (1984–1999) After the sale of the consumer electronics and computer divisions to Jack Tramiel, Atari was renamed Atari Games Corporation. Atari Games retained most of the same employees and managers from the coin-operated games division and continued many of the divisions projects from before the transition. In 1985, a controlling interest in the coin-operated games division was sold to Namco, which also took the Atari Games name. Warner renamed Atari Games to Atari Holdings, which continued as a non-operating subsidiary until 1992. Meanwhile, Namco later lost interest in operating Atari Games. In 1987, Namco sold 33% of its shares to a group of employees led by then-president Hideyuki Nakajima. He had been the president of Atari Games since 1985. Atari Ireland was a subsidiary of Atari Games that manufactured their games for the European market; while under Namco, Atari Ireland also manufactured Sega's Hang-On (1985) for the European market. Atari Games continued to manufacture arcade games and units, and starting in 1988, also sold cartridges for the Nintendo Entertainment System under the Tengen brand name, including a version of Tetris. The companies exchanged a number of lawsuits in the late 1980s related to disputes over the rights to Tetris and Tengen's circumvention of Nintendo's lockout chip, which prevented third parties from creating unauthorized games. The suit finally reached a settlement in 1994, with Atari Games paying Nintendo cash damages and use of several patent licenses. In April 1996, after an unsuccessful bid by Atari co-founder Nolan Bushnell, the company was sold to WMS Industries, owners of the Williams, Bally and Midway arcade brands, which restored the use of the Atari Games name. On November 19, 1999, Atari Games Corporation was renamed Midway Games West Inc., resulting in the Atari Games name no longer being used. Hasbro Interactive (1998–2000) On March 13, 1998, JTS sold the Atari name and assets to Hasbro Interactive for $5 million, less than a fifth of what Warner Communications had paid 22 years earlier. This transaction primarily involved the brand and intellectual property, which now fell under the Atari Interactive division of Hasbro Interactive. The brand name changed hands again in December 2000 when French software publisher Infogrames took over Hasbro Interactive. Atari SA (2001–present) In October 2001, Infogrames Entertainment SA (IESA, now Atari SA) announced that it was "reinventing" the Atari brand with the launch of three new games featuring a prominent Atari branding on their boxarts: Splashdown, MX Rider and TransWorld Surf. Infogrames used Atari as a brand name for games aimed at 18–34 year olds. Other Infogrames games under the Atari name included V-Rally 3, Neverwinter Nights, Stuntman and Enter the Matrix. On May 8, 2003, IESA had its majority-owned, but discrete US subsidiary Infogrames, Inc. officially renamed Atari, Inc., renamed its European operations to Atari Europe but kept the original name of the main company Infogrames Entertainment. The original Atari holdings division purchased from Hasbro, Hasbro Interactive, was also made a separate corporate entity renamed as Atari Interactive. Between 2004 and 2011, Atari produced and marketed Atari Flashback retro consoles, reminiscent of the Atari 2600 design. Since 2011, these consoles have been produced by AtGames under the license from Atari. Atari Flashback Portable is a handheld game console sold since 2016. In April 2011, Atari re-released their back catalogue of arcade and Atari 2600 games to be played on mobile devices. On March 6, 2008, IESA made an offer to Atari, Inc. to buy out all remaining public shares for a value of $1.68 per share, or $11 million total. The offer would make IESA sole owner of Atari, Inc., thus making it a privately held company. On April 30, 2008, Atari, Inc. announced its intentions to accept Infogrames' buyout offer and to merge with Infogrames. On October 8, 2008, IESA completed its acquisition of Atari, Inc., making it a wholly owned subsidiary. On December 9, 2008, Atari announced that it had acquired Cryptic Studios, a MMORPG developer. Namco Bandai purchased a 34% stake in Atari Europe on May 14, 2009, paving the way for its acquisition from IESA. Atari had significant financial issues for several years prior, with losses in the tens of millions since 2005. In May 2009, Infogrames Entertainment SA, the parent company of Atari, and Atari Interactive, announced it would change its name to Atari SA. In April 2010, Atari SA board member and former CEO David Gardner resigned. Original Atari co-founder Nolan Bushnell joined the board as a representative for Blubay holdings. As of March 31, 2011, the board of directors consisted of Frank Dangeard, Jim Wilson, Tom Virden, Gene Davis and Alexandra Fichelson. On January 21, 2013, the four related companies Atari, Atari Interactive, Humongous, and California US Holdings filed for Chapter 11 bankruptcy in the United States Bankruptcy Court for the Southern District of New York. All three Ataris emerged from bankruptcy one year later and the entering of the social casino gaming industry with Atari Casino. Frederic Chesnais, who now heads all three companies, stated that their entire operations consist of a staff of 10 people. On June 22, 2014, Atari announced a new corporate strategy that would include a focus on "new audiences", specifically "LGBT, social casinos, real-money gambling, and YouTube". On June 8, 2017, a short teaser video was released, promoting a new product; and the following week Chesnais confirmed the company was developing a new game console – the hardware was stated to be based on PC technology, and still under development. In mid July 2017 an Atari press release confirmed the existence of the aforementioned new hardware, referred to as the "Ataribox". The box design was derived from early Atari designs (e.g. 2600) with a ribbed top surface, and a rise at the back of the console; two versions were announced: one with a traditional wood veneer front, and the other with a glass front. Connectivity options were revealed, including HDMI, USB (x4), and SD card – the console was said to support both classic and current games. Also, according to an official company statement of June 22, 2017, the product was to be initially launched via a crowdfunding campaign in order to minimize any financial risk to the parent company. On September 26, 2017, Atari sent out a press release about the new "Atari VCS", which confirmed more details about the console. It will run a Linux operating system, with full access to the underlying OS, but it will have a custom interface designed for the TV. On January 27, 2020, Atari announced a deal with GSD Group to build Atari Hotels, with the first breaking ground in Phoenix in mid-2020. Additional hotels were also planned in Las Vegas, Denver, Chicago, Austin, Seattle, San Francisco, and San Jose. The company plans to make the hotel experience immersive and accessible to all ages. Hotels are planned to include virtual and augmented reality technologies. On December 16, 2020, Atari shipped the first units of the Atari VCS exclusive to backers of the systems crowdfunding campaign. Atari urged the backers to give feedback on the system so that the company could make changes to improve the product on its official launch. In 2020, Atari launched its decentralized cryptocurrency Atari Token in equal partnership with the ICICB Group. Atari Group announced in March 2020 that it granted ICICB a non-exclusive license to run a cryptocurrency online casino on Atari's website, based on the Atari Token. The group partnering with Atari opened a new company in Gibraltar called Atari Chain LTD. In March 2021, Atari extended its partnership with ICICB Group for the development of Atari branded hotels, and the first hotels will be constructed at selected locations outside the United States, with Dubai, Gibraltar and Spain. On 18 April 2022, Atari announced the termination of all license agreements with ICICB Group and its subsidiaries ("ICICB"). The license agreements between Atari and ICICB, including the Atari Chain Limited license (the "Joint Venture") and the related licenses including hotel and casino licenses, have been terminated effective 18 April 2022. ICICB is not authorized to represent Atari or its brands in any manner.

History Acadia began as an extension of Horton Academy in 1828, which was founded in Horton, Nova Scotia, by Baptists from Nova Scotia and Queen's College in 1838, who will be gathered into the Canadian Baptists of Atlantic Canada (Canadian Baptist Ministries). It was designed to prepare men for the ministry and to supply education for lay members. In 1838, the Nova Scotia Baptist Education Society founded Queen's College (named for Queen Victoria). The college began with 21 students in January 1839. The name "Queen's College" was denied to the Baptist school, so it was renamed "Acadia College" in 1841, in reference to the history of the area as an Acadian settlement. Acadia College awarded its first degrees in 1843 and became Acadia University in 1891, established by the Acadia University Act. The Granville Street Baptist Church (now First Baptist Church Halifax) was an instrumental and determining factor in the founding of the university. It has played a supporting role throughout its history, and shares much of the credit for its survival and development. Many individuals who have made significant contributions to Acadia University, including the first president John Pryor, were members of the First Baptist Church Halifax congregation. Similarly, the adjacent Wolfville United Baptist Church plays a significant role in the life of the university. This was unique at the time, and a direct result of Baptists being denied entry into other schools that required religious tests of their students and staff. In 1851, the power of appointing governors was transferred from the Nova Scotia Baptist Education Society to the Baptist Convention of the Maritime Provinces. Charles Osborne Wickenden, an architect, and J.C. Dumaresq designed the Central Building, Acadia College, 1878–79. Clara Belle Marshall, from Mount Hanley, Nova Scotia, became the first woman to graduate from Acadia University in 1879. In 1891, there were changes in the Act of Incorporation. Andrew R. Cobb designed several campus buildings including: Raynor Hall Residence, 1916; and Horton House, designed by Cobb in the Georgian style, and built by James Reid of Yarmouth, Nova Scotia, which was opened in 1915 as Horton Academy. Today, Horton Hall is the home of the Department of Psychology and Research and Graduate Studies. Emmerson Hall, built in 1913, is particularly interesting for the variety of building stones used. In 1967 Emmerson Hall was converted to classrooms and offices for the School of Education. It is a registered Heritage Property. Unveiled on 16 August 1963, a wooden and metal organ in Manning Chapel, Acadia University, is dedicated to Acadia University's war dead of the First and Second World Wars and the Korean War. A book of remembrance in Manning Chapel, Acadia University was unveiled on 1 March 1998 through the efforts of the Wolfville Historical Society. In 1966, it terminated its affiliation with the Canadian Baptists of Atlantic Canada (Canadian Baptist Ministries). The denomination maintains nine seats on the university's Board of Governors. Acadia is a laureate of Washington's Smithsonian Institution and a part of the permanent research collection of the National Museum of American History. Acadia is also the only Canadian university selected for inclusion in the Education and Academia category of the Computerworld Smithsonian Award. Faculty strikes Acadia University's Board of Governors and members of the Acadia University Faculty Association (AUFA) have ratified a new collective agreement covering the period 1 July 2010 to 30 June 2014. The faculty of Acadia University have been on strike three times in the history of the institution. The first was 24 February to 12 March 2004. The second was 15 October to 5 November 2007. The second strike was resolved after the province's labour minister, Mark Parent, appointed a mediator, on 1 November, to facilitate an agreement. The third strike began on 1 February 2022 and ended 1 March 2022 with both sides agreeing to binding arbitration. Academics Rankings In Maclean's 2023 Guide to Canadian Universities, Acadia was ranked fifth in the publication's "primarily undergraduate" Canadian university category, tied with Bishop's University. In the same year, the publication ranked Acadia 33rd, in Maclean's reputation survey. Faculties Acadia is organized into four faculties: Arts, Pure & Applied Science, Professional Studies and Theology. Each faculty is further divided into departments and schools specialized in areas of teaching and research. Research Acadia has over 15 research centres and 6 research chairs. Undergraduate students have the opportunity to participate in many research opportunities in a small university setting. The Division of Research & Graduate Studies is separate from the faculties and oversees graduate students as well as Acadia's research programs. Acadia's research programs explore coastal environments, ethno-cultural diversity, social justice, environmental monitoring and climate change, organizational relationships, data mining, the impact of digital technologies, and lifestyle choices contributing to health and wellness. Acadia's research centres include the Tidal Energy Institute, the Acadia Institute for Data Analytics, and the Beaubassin Field Station. Applied research opportunities include research with local wineries and grape growers, alternative insect control techniques and technologies. Innovation The Acadia Advantage In 1996, Acadia University pioneered the use of mobile computing technology in a post-secondary educational environment. This academic initiative, named the Acadia Advantage, integrated the use of notebook computers into the undergraduate curriculum and featured innovations in teaching. By 2000, all full-time, undergraduate Acadia students were taking part in the initiative. The initiative went beyond leasing notebook computers to students during the academic year, and included training, user support and the use of course-specific applications at Acadia that arguably revolutionized learning at the Wolfville, N.S. campus and beyond. Because of its pioneering efforts, Acadia is a laureate of Washington's Smithsonian Institution and a part of the permanent research collection of the National Museum of American History. It is the only Canadian university selected for inclusion in the Education and Academia category of the Computerworld Smithsonian Award. In addition, Acadia University received the Pioneer Award for Ubiquitous Computing. In 2001, it achieved high rankings in the annual Maclean's University Rankings, including Best Overall for Primarily Undergraduate University in their opinion survey, and it received the Canadian Information Productivity Award in 1997 as the first university in Canada to fully utilize information technology in the undergraduate curriculum. In October 2006, Dinter-Gottlieb established a commission to review the Acadia Advantage learning environment 10 years after inception. The mandate of the commission was to determine how well the current Advantage program meets the needs of students, faculty, and staff and to examine how the role of technology in the postsecondary environment has changed at Acadia, and elsewhere. The commission was asked to recommend changes and enhancements to the Acadia Advantage that would benefit the entire university community and ensure its sustainability. Some of the recommendations coming from the Acadia Advantage Renewal Report included developing a choice of model specifications and moving from Acadia-issued, student-leased notebook computers to a student-owned computer model. The university was also advised to unbundle its tuition structure so that the cost of an Acadia education is more detailed and students can understand how their investment in the future of the school is allotted. In September 2008, Acadia moved to a student-owned notebook computer version of the Acadia Advantage, now named Acadia Advantage 2.0. In 2017, Acadia announced the Huestis Innovation Pavilion as part of its $22.25 million Science Complex renewal project. Named in honour of lead donors, Faye and David Huestis of Saint John, New Brunswick, the Pavilion is a connection between Elliott and Huggins Halls, providing research and commercialization space. The new Agri-Technology Access Centre in the Innovation Pavilion provides companies and industry organizations with access to specialized technology, lab space, subject-matter expertise and commercialization support services. It also enables Acadia to advance its applied research strength in a priority sector – agriculture – and expand its technology transfer and commercialization activities. The Science Complex renewal project was supported by an investment of $15.98 million by the Federal and Provincial governments. Athletics Acadia's sports teams are called the Axemen and Axewomen. They participate in the Atlantic University Sports conference of U Sports. School spirit abounds with men's and women's varsity teams that have delivered more conference and national championships than any other institution in Atlantic University Sport. Routinely, more than one-third of Acadia's varsity athletes also achieve Academic All-Canadian designation through Canadian Interuniversity Sport by maintaining a minimum average of 80 per cent. Expansion and modernization of Raymond Field was completed in the fall of 2007 and features the installation of an eight-lane all-weather running track and a move to the same premium artificial turf used by the New England Patriots of the National Football League for its main playing field. The Raymond Field modernization was a gift to the university by friends, alumni, and the province. War Memorial Gymnasium also saw the installation of a new playing floor to benefit its basketball and volleyball teams. In September 2006, Acadia University announced its partnership with the Wolfville Tritons Swim Club and the Acadia Masters Swim Club to form the Acadia Swim Club and return competitive swimming to the university after a 14-year hiatus. On 26 September 2008, the university announced its intention to return swimming to a varsity status in September 2009. Fight song Notable among a number of songs commonly played and sung at various events such as commencement, convocation, and athletic games are: Stand Up and Cheer, the Acadia University fight song. According to 'Songs of Acadia College' (Wolfville, NS 1902–3, 1907), the songs include: 'Acadia Centennial Song' (1938); 'The Acadia Clan Song'; 'Alma Mater - Acadia;' 'Alma Mater Acadia' (1938) and 'Alma Mater Song.' Symbols In 1974, Acadia was granted a coat of arms designed by the College of Arms in London, England. The coat of arms is two-tone, with the school's official colours, garnet and blue, on the shield. The axes represent the school's origins in a rural setting, and the determination of its founders who cleared the land and built the school on donated items and labour. The open books represent the intellectual pursuits of a university, and the wolves heads are a whimsical representation of the university's location in Wolfville. "In pulvere vinces" (In dust you conquer) is the motto. The university seal depicts the Greek goddess of wisdom Athena in front of the first college hall. The university also uses a stylized "A" as a logo for its sports teams. Notable among a number of fight songs commonly played and sung at various events such as commencement, convocation, and athletic games are: the Acadia University alma mater set to the tune of "Annie Lisle". The lyrics are: Far above the dykes of Fundy And its basin blue Stands our noble alma mater Glorious to view Lift the chorus Speed it onward Sing it loud and free Hail to thee our alma mater Acadia, hail to thee Far above the busy highway And the sleepy town Raised against the arch of heaven Looks she proudly down Historic buildings at Acadia University Seminary House, also known as just "Sem", is a Second Empire style-building constructed in 1878 as a home for women attending the university. It was designated a National Historic Site of Canada in 1997 as Canada's oldest facility associated with the higher education of women. The building now serves as a co-ed residence, and Whitman House on campus now serves as the women's only residence. Carnegie Hall, built in 1909, is a large, two-storey, Neo-classical brick building. It was designated under the provincial Heritage Property Act in 1989 as its construction in 1909 signified Acadia's evolution from classical college to liberal university. The War Memorial House (more generally known as Barrax), which is a residence, and War Memorial Gymnasium are landmark buildings on the campus of Acadia University. The Memorial Hall and Gymnasium honours students who had enlisted and died in the First World War, and in the Second World War. Two granite shafts, which are part of the War Memorial Gymnasium complex at Acadia University, are dedicated to the university's war dead. The War Memorial House is dedicated to the war dead from Acadia University during the Second World War. Student life At Acadia University, students have access to the Student Union Building which serves as a hub for students and houses many Student Union organizations. The building houses The Axe Lounge, a convenience store, an information desk, two food outlets, and the Sexual Health Resource Centre. The university press, The Athenaeum is a member of CUP. There is a student-ran radio, available at https://www.axeradio.net/. Student government All students are represented by the Acadia Students' Union. Residences Approximately 1500 students live on-campus in 11 residences: Chase Court Chipman House Christofor Hall Crowell Tower (13 Story High-rise) Cutten House Dennis House - First floor houses student health services Eaton House Roy Jodrey Hall Seminary House - Also houses the School of Education in lower level War Memorial (Barrax) House Whitman House (Tully) - All female residence Willett House (former residence) People List of presidents and vice chancellors John Pryor, 1846–1850 John Cramp, 1851–1853 (and 1856–1869) Edmund Crawley, 1853–1856 John Cramp, 1856–1869 Artemas Wyman Sawyer, 1869–1896 Thomas Trotter, 1897–1906 W.B.

Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way. Whereas a biotic stress would include living disturbances such as fungi or harmful insects, abiotic stress factors, or stressors, are naturally occurring, often intangible and inanimate factors such as intense sunlight, temperature or wind that may cause harm to the plants and animals in the area affected. Abiotic stress is essentially unavoidable. Abiotic stress affects animals, but plants are especially dependent, if not solely dependent, on environmental factors, so it is particularly constraining. Abiotic stress is the most harmful factor concerning the growth and productivity of crops worldwide. Research has also shown that abiotic stressors are at their most harmful when they occur together, in combinations of abiotic stress factors. Examples Abiotic stress comes in many forms. The most common of the stressors are the easiest for people to identify, but there are many other, less recognizable abiotic stress factors which affect environments constantly. The most basic stressors include: High winds Extreme temperatures Drought Flood Other natural disasters, such as tornadoes and wildfires. Cold Heat Nutrient deficiency Lesser-known stressors generally occur on a smaller scale. They include: poor edaphic conditions like rock content and pH levels, high radiation, compaction, contamination, and other, highly specific conditions like rapid rehydration during seed germination. Effects Abiotic stress, as a natural part of every ecosystem, will affect organisms in a variety of ways. Although these effects may be either beneficial or detrimental, the location of the area is crucial in determining the extent of the impact that abiotic stress will have. The higher the latitude of the area affected, the greater the impact of abiotic stress will be on that area. So, a taiga or boreal forest is at the mercy of whatever abiotic stress factors may come along, while tropical zones are much less susceptible to such stressors. Benefits One example of a situation where abiotic stress plays a constructive role in an ecosystem is in natural wildfires. While they can be a human safety hazard, it is productive for these ecosystems to burn out every once in a while so that new organisms can begin to grow and thrive. Even though it is healthy for an ecosystem, a wildfire can still be considered an abiotic stressor, because it puts an obvious stress on individual organisms within the area. Every tree that is scorched and each bird nest that is devoured is a sign of the abiotic stress. On the larger scale, though, natural wildfires are positive manifestations of abiotic stress. What also needs to be taken into account when looking for benefits of abiotic stress, is that one phenomenon may not affect an entire ecosystem in the same way. While a flood will kill most plants living low on the ground in a certain area, if there is rice there, it will thrive in the wet conditions. Another example of this is in phytoplankton and zooplankton. The same types of conditions are usually considered stressful for these two types of organisms. They act very similarly when exposed to ultraviolet light and most toxins, but at elevated temperatures the phytoplankton reacts negatively, while the thermophilic zooplankton reacts positively to the increase in temperature. The two may be living in the same environment, but an increase in temperature of the area would prove stressful only for one of the organisms. Lastly, abiotic stress has enabled species to grow, develop, and evolve, furthering natural selection as it picks out the weakest of a group of organisms. Both plants and animals have evolved mechanisms allowing them to survive extremes. Detriments The most obvious detriment concerning abiotic stress involves farming. It has been claimed by one study that abiotic stress causes the most crop loss of any other factor and that most major crops are reduced in their yield by more than 50% from their potential yield. Because abiotic stress is widely considered a detrimental effect, the research on this branch of the issue is extensive. For more information on the harmful effects of abiotic stress, see the sections below on plants and animals. In plants A plant's first line of defense against abiotic stress is in its roots. If the soil holding the plant is healthy and biologically diverse, the plant will have a higher chance of surviving stressful conditions. The plant responses to stress are dependent on the tissue or organ affected by the stress. For example, transcriptional responses to stress are tissue or cell specific in roots and are quite different depending on the stress involved. One of the primary responses to abiotic stress such as high salinity is the disruption of the Na+/K+ ratio in the cytoplasm of the plant cell. High concentrations of Na+, for example, can decrease the capacity for the plant to take up water and also alter enzyme and transporter functions. Evolved adaptations to efficiently restore cellular ion homeostasis have led to a wide variety of stress tolerant plants. Facilitation, or the positive interactions between different species of plants, is an intricate web of association in a natural environment. It is how plants work together. In areas of high stress, the level of facilitation is especially high as well. This could possibly be because the plants need a stronger network to survive in a harsher environment, so their interactions between species, such as cross-pollination or mutualistic actions, become more common to cope with the severity of their habitat. Plants also adapt very differently from one another, even from a plant living in the same area. When a group of different plant species was prompted by a variety of different stress signals, such as drought or cold, each plant responded uniquely. Hardly any of the responses were similar, even though the plants had become accustomed to exactly the same home environment. Serpentine soils (media with low concentrations of nutrients and high concentrations of heavy metals) can be a source of abiotic stress. Initially, the absorption of toxic metal ions is limited by cell membrane exclusion. Ions that are absorbed into tissues are sequestered in cell vacuoles. This sequestration mechanism is facilitated by proteins on the vacuole membrane. An example of plants that adapt to serpentine soil are Metallophytes, or hyperaccumulators, as they are known for their ability to absorbed heavy metals using the root-to-shoot translocation (which it will absorb into shoots rather than the plant itself). They're also extinguished for their ability to absorb toxic substances from heavy metals. Chemical priming has been proposed to increase tolerance to abiotic stresses in crop plants. In this method, which is analogous to vaccination, stress-inducing chemical agents are introduced to the plant in brief doses so that the plant begins preparing defense mechanisms. Thus, when the abiotic stress occurs, the plant has already prepared defense mechanisms that can be activated faster and increase tolerance. Prior exposure to tolerable doses of biotic stresses such as phloem-feeding insect infestation have also been shown to increase tolerance to abiotic stresses in plant Impact on food production Abiotic stress mostly affects plants used in agriculture. Some examples of adverse conditions (which may be caused by climate change) are high or low temperatures, drought, salinity, and toxins. Rice (Oryza sativa) is a classic example. Rice is a staple food throughout the world, especially in China and India. Rice plants can undergo different types of abiotic stresses, like drought and high salinity. These stress conditions adversely affect rice production. Genetic diversity has been studied among several rice varieties with different genotypes, using molecular markers. Chickpea production is affected by drought. Chickpeas are one of the most important foods in the world. Wheat is another major crop that is affected by drought: lack of water affects the plant development, and can wither the leaves. Maize crops can be affected by high temperature and drought, leading to the loss of maize crops due to poor plant development. Soybean is a major source of protein, and its production is also affected by drought. Salt stress in plants Soil salinization, the accumulation of water-soluble salts to levels that negatively impact plant production, is a global phenomenon affecting approximately 831 million hectares of land. More specifically, the phenomenon threatens 19.5% of the world's irrigated agricultural land and 2.1% of the world's non-irrigated (dry-land) agricultural lands. High soil salinity content can be harmful to plants because water-soluble salts can alter osmotic potential gradients and consequently inhibit many cellular functions. For example, high soil salinity content can inhibit the process of photosynthesis by limiting a plant's water uptake; high levels of water-soluble salts in the soil can decrease the osmotic potential of the soil and consequently decrease the difference in water potential between the soil and the plant's roots, thereby limiting electron flow from H2O to P680 in Photosystem II's reaction center. Over generations, many plants have mutated and built different mechanisms to counter salinity effects. A good combatant of salinity in plants is the hormone ethylene. Ethylene is known for regulating plant growth and development and dealing with stress conditions. Many central membrane proteins in plants, such as ETO2, ERS1 and EIN2, are used for ethylene signaling in many plant growth processes. Mutations in these proteins can lead to heightened salt sensitivity and can limit plant growth. The effects of salinity has been studied on Arabidopsis plants that have mutated ERS1, ERS2, ETR1, ETR2 and EIN4 proteins. These proteins are used for ethylene signaling against certain stress conditions, such as salt and the ethylene precursor ACC is used to suppress any sensitivity to the salt stress. Phosphate starvation in plants Phosphorus (P) is an essential macronutrient required for plant growth and development, but it is present only in limited quantities in most of the world's soil. Plants use P mainly in the form of soluble inorganic phosphates (PO4−−−) but are subject to abiotic stress when there is not enough soluble PO4−−− in the soil. Phosphorus forms insoluble complexes with Ca and Mg in alkaline soils and with Al and Fe in acidic soils that make the phosphorus unavailable for plant roots. When there is limited bioavailable P in the soil, plants show extensive symptoms of abiotic stress, such as short primary roots and more lateral roots and root hairs to make more surface available for phosphate absorption, exudation of organic acids and phosphatase to release phosphates from complex P–containing molecules and make it available for growing plants' organs. It has been shown that PHR1, a MYB-related transcription factor, is a master regulator of P-starvation response in plants. PHR1 also has been shown to regulate extensive remodeling of lipids and metabolites during phosphorus limitation stress Drought stress Drought stress, defined as naturally occurring water deficit, is a main cause of crop losses in agriculture. This is because water is essential for many fundamental processes in plant growth. It has become especially important in recent years to find a way to combat drought stress. A decrease in precipitation and consequent increase in drought are extremely likely in the future due to an increase in global warming. Plants have come up with many mechanisms and adaptations to try and deal with drought stress. One of the leading ways that plants combat drought stress is by closing their stomata. A key hormone regulating stomatal opening and closing is abscisic acid (ABA). Synthesis of ABA causes the ABA to bind to receptors. This binding then affects the opening of ion channels, thereby decreasing turgor pressure in the stomata and causing them to close. Recent studies, by Gonzalez-Villagra, et al., have showed how ABA levels increased in drought-stressed plants (2018). They showed that when plants were placed in a stressful situation they produced more ABA to try to conserve any water they had in their leaves. Another extremely important factor in dealing with drought stress and regulating the uptake and export of water is aquaporins (AQPs). AQPs are integral membrane proteins that make up channels. These channels' main job is the transport of water and other essential solutes. AQPs are both transcriptionally and post-transcriptionally regulated by many different factors such as ABA, GA3, pH and Ca2+; and the specific levels of AQPs in certain parts of the plant, such as roots or leaves, helps to draw as much water into the plant as possible. By understanding the mechanisms of both AQPs and the hormone ABA, scientists will be better able to produce drought-resistant plants in the future. It is interesting that plants that are consistently exposed to drought have been found to form a sort of "memory". A study by Tombesi et al., found that plants which had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants which were exposed to drought conditions actually changed the way they regulated their stomata and what they called "hydraulic safety margin" so as to decrease the vulnerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better when less water was available. In animals For animals, the most stressful of all the abiotic stressors is heat. This is because many species are unable to regulate their internal body temperature. Even in the species that are able to regulate their own temperature, it is not always a completely accurate system. Temperature determines metabolic rates, heart rates, and other very important factors within the bodies of animals, so an extreme temperature change can easily distress the animal's body. Animals can respond to extreme heat, for example, through natural heat acclimation or by burrowing into the ground to find a cooler space. It is also possible to see in animals that a high genetic diversity is beneficial in providing resiliency against harsh abiotic stressors. This acts as a sort of stock room when a species is plagued by the perils of natural selection. A variety of galling insects are among the most specialized and diverse herbivores on the planet, and their extensive protections against abiotic stress factors have helped the insect in gaining that position of honor. In endangered species Biodiversity is determined by many things, and one of them is abiotic stress. If an environment is highly stressful, biodiversity tends to be low. If abiotic stress does not have a strong presence in an area, the biodiversity will be much higher. This idea leads into the understanding of how abiotic stress and endangered species are related. It has been observed through a variety of environments that as the level of abiotic stress increases, the number of species decreases. This means that species are more likely to become population threatened, endangered, and even extinct, when and where abiotic stress is especially harsh.

Apostolic succession is the method whereby the ministry of the Christian Church is considered by some Christian denominations to be derived from the apostles by a continuous succession, which has usually been associated with a claim that the succession is through a series of bishops. Those of the Anglican, Church of the East, Eastern Orthodox, Hussite, Moravian, Old Catholic, Oriental Orthodox, Catholic and Scandinavian Lutheran traditions maintain that "a bishop cannot have regular or valid orders unless he has been consecrated in this apostolic succession". These traditions do not always consider the episcopal consecrations of all of the other traditions as valid. This series was seen originally as that of the bishops of a particular see founded by one or more of the apostles. According to historian Justo L. González, apostolic succession is generally understood today as meaning a series of bishops, regardless of see, each consecrated by other bishops, themselves consecrated similarly in a succession going back to the apostles. According to the Joint International Commission for Theological Dialogue Between the Catholic Church and the Orthodox Church, "apostolic succession" means more than a mere transmission of powers. It is succession in a church which witnesses to the apostolic faith, in communion with the other churches, witnesses of the same apostolic faith. The "see (cathedra) plays an important role in inserting the bishop into the heart of ecclesial apostolicity", but once ordained, the bishop becomes in his church the guarantor of apostolicity and becomes a successor of the apostles. Those who hold for the importance of apostolic succession via episcopal laying on of hands appeal to the New Testament which, they say, implies a personal apostolic succession (from Paul to Timothy and Titus, for example). They appeal as well to other documents of the early Church, especially the Epistle of Clement. In this context, Clement explicitly states that the apostles appointed bishops as successors and directed that these bishops should in turn appoint their own successors; given this, such leaders of the Church were not to be removed without cause and not in this way. Further, proponents of the necessity of the personal apostolic succession of bishops within the Church point to the universal practice of the undivided early Church (up to AD 431), before it was divided into the Church of the East, Oriental Orthodoxy, the Eastern Orthodox Church and the Roman Catholic Church. Some Christians, including certain nonconformist Protestants, deny the need for this type of continuity, and the historical claims involved have been severely questioned by them; Anglican academic Eric G. Jay comments that the account given of the emergence of the episcopate in Chapter III of the dogmatic constitution Lumen gentium (1964) "is very sketchy, and many ambiguities in the early history of the Christian ministry are passed over". Various meanings Michael Ramsey, an English Anglican bishop and the Archbishop of Canterbury (1961–1974), described three meanings of "apostolic succession": One bishop succeeding another in the same see meant that there was a continuity of teaching: "while the Church as a whole is the vessel into which the truth is poured, the Bishops are an important organ in carrying out this task". The bishops were also successors of the apostles in that "the they performed of preaching, governing and ordaining were the same as the Apostles had performed". It is also used to signify that "grace is transmitted from the Apostles by each generation of bishops through the imposition of hands". He adds that this last has been controversial in that it has been claimed that this aspect of the doctrine is not found before the time of Augustine of Hippo, while others allege that it is implicit in the Church of the second and third centuries. In its 1982 statement on Baptism, Eucharist and Ministry, the Faith and Order Commission of the World Council of Churches stated that "the primary manifestation of apostolic succession is to be found in the apostolic tradition of the Church as a whole. ... Under the particular historical circumstances of the growing Church in the early centuries, the succession of bishops became one of the ways, together with the transmission of the Gospel and the life of the community, in which the apostolic tradition of the Church was expressed." It spoke of episcopal succession as something that churches that do not have bishops can see "as a sign, though not a guarantee, of the continuity and unity of the Church" and that all churches can see "as a sign of the apostolicity of the life of the whole church". The Porvoo Common Statement (1996), agreed to by the Anglican churches of the British Isles and most of the Lutheran churches of Scandinavia and the Baltic, echoed the Munich (1982) and Finland (1988) statements of the Joint International Commission for Theological Dialogue between the Roman Catholic Church and the Orthodox Church by stating that "the continuity signified in the consecration of a bishop to episcopal ministry cannot be divorced from the continuity of life and witness of the diocese to which he is called". Some Anglicans, in addition to other Protestants, held that apostolic succession "may also be understood as a continuity in doctrinal teaching from the time of the apostles to the present". For example, the British Methodist Conference locates the "true continuity" with the Church of past ages in "the continuity of Christian experience, the fellowship in the gift of the one Spirit; in the continuity in the allegiance to one Lord, the continued proclamation of the message; the continued acceptance of the mission". The teaching of the Second Vatican Council on apostolic succession has been summed up as follows: In the early Fathers According to International Theological Commission (ITC), conflicts could not always be avoided between individuals among the New Testament communities; Paul appealed to his apostolic authority when there was a disagreement about the Gospel or principles of Christian life. How the development of apostolic government proceeded is difficult to say accurately because of the paucity of relevant documents. ITC says that the apostles or their closest assistants or their successors directed the local colleges of episkopoi and presbyteroi by the end of the first century; while by the beginning of the second century the figure of a single bishop, as the head of the communities, appears explicitly in the letters of Ignatius of Antioch ( 35-107). In the Epistle to the Smyrnaeans, Ignatius wrote about three degrees ministry: Ramsey says that the doctrine was formulated in the second century in the first of the three senses given by him, originally as a response to Gnostic claims of having received secret teaching from Christ or the apostles; it emphasised the public manner in which the apostles had passed on authentic teaching to those whom they entrusted with the care of the churches they founded and that these in turn had passed it on to their successors. Ramsey argues that only later was it given a different meaning, a process in which Augustine (Bishop of Hippo Regis, 395–430) played a part by emphasising the idea of "the link from consecrator to consecrated whereby the grace of order was handed on". Writing in about AD 94, Clement of Rome states that the apostles appointed successors to continue their work where they had planted churches and for these in their turn to do the same because they foresaw the risk of discord: "Our Apostles, too, by the instruction of our Lord Jesus Christ, knew that strife would arise concerning the dignity of a bishop; and on this account, having received perfect foreknowledge, they appointed the above-mentioned as bishops and deacons: and then gave a rule of succession, in order that, when they had fallen asleep, other men, who had been approved, might succeed to their ministry." According to Anglican Eric G. Jay, the interpretation of his writing is disputed, but it is clear that he supports some sort of approved continuation of the ministry exercised by the apostles which in its turn was derived from Christ. Hegesippus (180?) and Irenaeus (180) introduce explicitly the idea of the bishop's succession in office as a guarantee of the truth of what he preached in that it could be traced back to the apostles, and they produced succession lists to back this up. That this succession depended on the fact of ordination to a vacant see and the status of those who administered the ordination is seldom commented on. Woollcombe also states that no one questioned the apostolicity of the See of Alexandria despite the fact that its popes were consecrated by the college of presbyters up till the time of the Council of Nicaea in 325. On the contrary, other sources clearly state that Mark the Evangelist is the first bishop of Alexandria (Pope of Alexandria); then he ordained Annianus as his successor bishop (2nd Pope) as told by Eusebius. James F. Puglisi, director of Centro Pro Unione, made a conclusion about Irenaeus' writings: "the terms episkopos and presbyteros are interchangeable, but the term episkopos [bishop] is applied to the person who is established in every Church by the apostles and their successors". According to Eric G. Jay, Irenaeus also refers to a succession of presbyters who preserve the tradition "which originates from the apostles" and later goes on to speak of their having "an infallible gift of truth" [charisma veritatis certum]. Jay comments that this is sometimes seen as an early reference to the idea of the transmission of grace through the apostolic succession which in later centuries was understood as being specifically transmitted through the laying on of hands by a bishop within the apostolic succession (the "pipeline theory"). He warns that this is open to the grave objection that it makes grace a (quasi)material commodity and represents an almost mechanical method of imparting what is by definition a free gift. He adds that the idea cannot be squeezed out of Irenaeus' words. Writing a little later, Tertullian makes the same main point but adds expressly that recently founded churches (such as his own in Carthage) could be considered apostolic if they had "derived the tradition of faith and the seeds of doctrine" from an apostolic church. His disciple, Cyprian (Bishop of Carthage 248–58) appeals to the same fundamental principle of election to a vacant see in the aftermath of the Decian Persecution when denying the legitimacy of his rigorist rival in Carthage and that of the anti-pope Novatian in Rome. The emphasis is now on legitimating Cyprian's episcopal ministry as a whole and specifically his exclusive right to administer discipline to the lapsed rather than on the content of what is taught. Cyprian also laid great emphasis on the fact that any minister who broke with the Church lost ipso facto the gift of the Spirit which had validated his orders. This meant that the minister would have no power or authority to celebrate an efficacious sacrament. As transmission of grace For the adherents of this understanding of apostolic succession, grace is transmitted during episcopal consecrations (the ordination of bishops) by the laying on of hands of bishops previously consecrated within the apostolic succession. They hold that this lineage of ordination derives from the Twelve Apostles, thus making the Church the continuation of the early Apostolic Christian community. They see it as one of four elements that define the true Church of Jesus Christ, and legitimize the ministry of its clergy, since only a bishop within the succession can perform valid ordinations and only bishops and presbyters (priests) ordained by bishops in the apostolic succession can validly celebrate (or "confect") several of the other sacraments, including the Eucharist, reconciliation of penitents, confirmation and anointing of the sick. Everett Ferguson argued that Hippolytus, in Apostolic Tradition 9, is the first known source to state that only bishops have the authority to ordain; and normally at least three bishops were required to ordain another bishop. Cyprian also asserts that "if any one is not with the bishop, he is not in the church". This position was stated by John Henry Newman, before his conversion from Anglicanism to Roman Catholicism, in Tracts for the Times: We [priests of the Church of England] have been born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. The Lord Jesus Christ gave His Spirit to His Apostles; they in turn laid their hands on those who should succeed them; and these again on others; and so the sacred gift has been handed down to our present bishops, who have appointed us as their assistants, and in some sense representatives. ... we must necessarily consider none to be ordained who have not been ordained. Ferguson, in Encyclopedia of Early Christianity, says that example of James and the elders (presbyters) of the Jerusalem Church (Acts 21:18) may have provided a model for the development of 'monepiscopacy', in which James' position has figured conspicuously in modern theories about the rise of the monepiscopacy. Raymond E. Brown says that in the earlier stage (before the third century and perhaps earlier) there were plural bishops or overseers ("presbyter-bishops") in an individual community; in the later stage changed to only one bishop per community. Little is known about how the early bishops were formally chosen or appointed; afterwards the Church developed a regularized pattern of selection and ordination of bishops, and from the third century on that was universally applied. Brown asserts that the ministry was not ordained by the Church to act on its own authority, but as an important part to continue the ministry of Jesus Christ and helps to make the Church what it is. Raymond E. Brown also states that by the early second century, as written in the letters of Ignatius of Antioch, in the threefold structure of the single bishop, plural presbyters, and plural deacons, the celebration of the Eucharist is assigned to the bishop alone; the bishop may delegate others when he goes away. At the Last Supper, Jesus says to those present, who were or included the Twelve Apostles, "Do this in remembrance of me," Brown presumes that the Twelve were remembered as presiding at the Eucharist. But they could scarcely have been present at all the Eucharists of the first century, and no information in New Testament whether a person was regularly assigned to do this task and, if so, who that person was. After all the Church regulated and regularized the celebration of the Eucharist, as that was an inevitable establishment if communities were to be provided regularly with the 'bread of life', since it could not rely on gratuitous provision. Objections to the transmission of grace theory According to William Griffith Thomas, some Protestants have objected that this theory is not explicitly found in Scripture, and the New Testament uses 'bishop' and 'presbyter' as alternative names for the same office. Michael Ramsey argued it is not clearly found in the writings of the Fathers before Augustine in the fourth century and there were attempts to read it back as implicit in earlier writers. For example, C. K. Barrett points out that the Pastoral Epistles are concerned that ministers of the generation of Timothy and Titus should pass on the doctrine they had received to the third generation. According to Barrett, teaching and preaching are "the main, almost the only, activities of ministry". He argues that in Clement of Rome ministerial activity is liturgical: the undifferentiated 'presbyter-bishops' are to "make offerings to the Lord at the right time and in the right places" something which is simply not defined by the evangelists. He also mentions the change in the use of sacrificial language as a more significant still: for Paul the Eucharist is a receiving of gifts from God, the Christian sacrifice is the offering of one's body. Moving on to Ignatius of Antioch, Barrett states that a sharp distinction is found between 'presbyter' and 'bishop': the latter now stands out as "an isolated figure" who is to be obeyed and without whom it is not lawful to baptise or hold a love-feast. He also points out that when Ignatius writes to the Romans, there is no mention of a bishop of the Roman Church, "which we may suppose had not yet adopted the monarchical episcopate". Jalland comes to a similar conclusion and locates the change from the "polyepiscopacy" of the house church model in Rome, to monepiscopacy as occurring before the middle of the second century. Similar objections are voiced by Harvey who comments that there is a "strong and ancient tradition" that the presence of an ordained man is necessary for the celebration of the Eucharist. But, according to him, there is "certainly no evidence for this view in the New Testament" and in the case of Clement of Rome and Ignatius of Antioch the implication is not that it be celebrated by anyone else, but that it not. Harvey says in the third century this "concern for propriety" begins to be displaced by the concept of 'power' to do so which means that in the absence of such a man it is "literally impossible" for a Eucharist to be celebrated. Apostolicity as doctrinal and related continuity Some Protestant denominations, not including Scandinavian Lutherans, Anglicans and Moravians, deny the need of maintaining episcopal continuity with the early Church, holding that the role of the apostles was that, having been chosen directly by Jesus as witnesses of his resurrection, they were to be the "special instruments of the Holy Spirit in founding and building up the Church". Anglican theologian E. A. Litton argues that the Church is "built upon 'the foundation of the Prophets and Apostles', but a foundation does not repeat itself"; therefore he says that when the apostles died, they were replaced by their writings. To share with the apostles the same faith, to believe their word as found in the Scriptures, to receive the same Holy Spirit, is to many Protestants the only meaningful "continuity". The most meaningful apostolic succession for them, then, is a "faithful succession" of apostolic teaching. Max Thurian, before his conversion to Roman Catholicism in 1988, described the classic Reformed/Presbyterian concept of apostolic succession in the following terms. "The Christian ministry is not derived from the people but from the pastors; a scriptural ordinance provides for this ministry being renewed by the ordination of a presbyter by presbyters; this ordinance originates with the apostles, who were themselves presbyters, and through them it goes back to Christ as its source.". Then he continued: "it does not guarantee the continuity and faithfulness of the Church. A purely historical or mechanical succession of ministers, bishops or pastors would not mean ipso facto true apostolic succession in the church, Reformed tradition, following authentic Catholic tradition, distinguishes four realities which make up the true apostolic succession, symbolized, but not absolutely guaranteed, by ministerial succession." At the same time Thurian argued that the realities form a "composite faithfulness" and are (i) "perseverance in the apostolic doctrine"; (ii) "the will to proclaim God's word"; (iii) "communion in the fundamental continuity of the Church, the Body of Christ, the faithful celebration of Baptism and the Eucharist"; (iv) "succession in the laying on of hands, the sign of ministerial continuity". According to Walter Kasper, the Reformed-Catholic dialogue came to belief that there is an apostolic succession which is important to the life of the Church, though both sides distinguish the meaning of that succession. Besides, the dialogue states that apostolic succession "consists at least in continuity of apostolic doctrine, but this is not in opposition to succession through continuity of ordained ministry". While the Lutheran-Catholic dialogue distinguished between apostolic succession in faith (in substantive meaning) and apostolic succession as ministerial succession of bishops, it agreed that "succession in the sense of the succession of ministers must be seen within the succession of the whole church in the apostolic faith". The Joint International Commission for Theological Dialogue Between the Catholic Church and the Orthodox Church asserts that apostolic succession means something more than just a transmission of authorities; it witnesses to the apostolic faith from the same apostolic faith, and in communion with other churches (attached to the apostolic communion). Apostolic tradition deals with the community, not only an ordained bishop as an isolated person. Since the bishop, once ordained, becomes the guarantor of apostolicity and successor of the apostles; he joins all the bishops, thus maintaining episkope of the local churches derived from the college of the apostles. Churches claiming apostolic succession Churches that claim some form of episcopal apostolic succession, dating back to the apostles or to leaders from the apostolic era, include: the Roman Catholic Church the Eastern Orthodox Church the Oriental Orthodox Churches the Church of the East the Moravian Church the Anglican Communion many Lutheran churches Old Catholics and other Independent Catholics (those incorporating the term "Catholic") some churches in the Convergence Movement The Anglican Communion and those Lutheran churches which claim apostolic succession do not specifically teach this but exclusively practice episcopal ordination. While some Anglicans claim it for their communion, their views are often nuanced and there is widespread reluctance to 'unchurch' Christian bodies which lack it. Roman Catholics recognize the validity of the apostolic successions of the bishops, and therefore the rest of the clergy, of the Eastern Orthodox, Oriental Orthodox, Church of the East, and Polish National Catholic Church. The Orthodox generally recognize Roman Catholic clerical orders as being of apostolic lineage, but have a different concept of the apostolic succession as it exists outside the canonical borders of the Eastern Orthodox Church, extending the term only to bishops who have maintained communion, received ordination from a line of apostolic bishops, and preserved the catholic faith once delivered through the apostles and handed down as holy tradition. The lack of apostolic succession through bishops is the primary basis on which Protestant denominations (barring some like Anglicans and Old Catholics) are not called churches, in the proper sense, by the Orthodox and Roman Catholic churches, the latter referring to them as "ecclesial communities" in the official documents of the Second Vatican Council. The Church of Jesus Christ of Latter-day Saints also claims apostolic succession. According to Latter-day Saint tradition, in 1829, Joseph Smith received the priesthood from a visit from heaven of Jesus' disciples Peter, James, and John. After its establishment, each subsequent prophet and leader of the church have received the authority passed down by the laying on of hands, or through apostolic succession. Orthodox, Roman Catholic, and Protestant Christians reject the claim that Smith possessed direct or indirect apostolic authority. Apostolic founders An early understanding of apostolic succession is represented by the traditional beliefs of various churches, as organised around important episcopal sees, to have been founded by specific apostles. On the basis of these traditions, the churches hold they have inherited specific authority, doctrines or practices on the authority of their founding apostle(s), which is understood to be continued by the bishops of the apostolic throne of the church that each founded and whose original leader he was. Thus: The See of Rome, the head see of the Catholic Church, states that it was founded by Simon Peter (traditionally called "Prince of the Apostles" and "Chief of the Apostles") and Paul the Apostle. Although Peter also founded the See of Antioch, the See of Rome claims the full authority of Peter (who, according to Catholic doctrine, was the visible head of the church and the sole chief of the Apostles) exclusively for itself, because Peter died as the Bishop of Rome, and not of another see. The Ecumenical Patriarchate of Constantinople, the primary patriarchate of the Eastern Orthodox Church, states that Apostle Andrew (elder brother of Simon Peter) was its founder. Each Patriarchate of Alexandria (the Greek Orthodox Church of Alexandria, the Coptic Catholic Church, and the Coptic Orthodox Church) states that it was founded by Mark the Evangelist. Each Patriarchate of Antioch (the Greek Orthodox Church of Antioch, the Syriac Orthodox Church, the Maronite Church, the Melkite Greek Catholic Church, and the Syriac Catholic Church) states that it was founded by Simon Peter. The Eastern Orthodox Patriarchate of Jerusalem states that it was founded by James the Just. Each Armenian Church (the Armenian Apostolic Church, based at Etchmiadzin, and the Armenian Catholic Church, whose patriarchal see is Cilicia but is based at Beirut) states that it was founded by the Apostles Bartholomew and Jude Thaddeus. The following bodies state they were founded by the Apostle Thomas: the Assyrian Church of the East, the Ancient Church of the East and the Chaldean Catholic Church, originating in or around Mesopotamia, and churches based in Kerala, India having Syriac roots and generically known as the Saint Thomas Christians: the Syro-Malabar Catholic Church, the Syro-Malankara Catholic Church, the Jacobite Syrian Christian Church, the Malankara Orthodox Syrian Church, and the Mar Thoma Syrian Church. The Orthodox Tewahedo churches (the Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church) state that they were founded by Philip the Evangelist and Mark the Evangelist. The Orthodox Church of Georgia states that the Apostles Andrew and Simon the Zealot were its founders. The Orthodox Church of Cyprus, based at Nova Justiniana (Erdek), states that it was founded by the Apostles Paul and Barnabas. The Bulgarian Orthodox Church states that it has a connection with Andrew the Apostle. The Russian Orthodox Church states that it has a connection with the Apostle Andrew, who is said to have visited the area where the city of Kyiv later arose. Teachings Teachings on the nature of apostolic succession vary depending on the ecclesiastic body, especially within various Protestant denominations. Christians of the Church of the East, Oriental Orthodox, Eastern Orthodox Church and the Roman Catholic Church teach apostolic succession. Among the previously mentioned churches opinions vary as to the validity of succession within Old Catholic, Anglican, Moravian, and Lutheran communities. Roman Catholic Church In Catholic theology, the doctrine of apostolic succession is that the apostolic tradition – including apostolic teaching, preaching, and authority – is handed down from the college of apostles to the college of bishops through the laying on of hands, as a permanent office in the Church. Historically, this has been understood as a succession in office, a succession of valid ordinations, or a succession of the entire college. It is understood as a sign and guarantee that the Church, both local and universal, is in diachronic continuity with the apostles; a necessary but insufficient guarantor thereof. Papal primacy is different though related to apostolic succession as described here. The Roman Catholic Church has traditionally claimed a unique leadership role for the Apostle Peter, believed to have been named by Jesus as head of the Apostles and as a focus of their unity, who became the first Bishop of Rome, and whose successors inherited the role and accordingly became the leaders of the worldwide Church as well. Even so, Roman Catholicism acknowledges the papacy is built on apostolic succession, not the other way around. As such, apostolic succession is a foundational doctrine of authority in the Catholic Church. Peter was succeeded by Linus, Linus by Clement, Clement by Anacletus, Anacletus by Evaristus..." The Roman Catholic position is summarised this way: "The Lord says to Peter: 'I say to you,' he says, 'that you are Peter, and upon this rock I will build my Church, and the gates of hell will not overcome it ....' On him [Peter] he builds the Church, and to him he gives the command to feed the sheep, and although he assigns a like power to all the apostles, yet he founded a single chair [cathedra], and he established by his own authority a source and an intrinsic reason for that unity.... If someone [today] does not hold fast to this unity of Peter, can he imagine that he still holds the faith? If he [should] desert the chair of Peter upon whom the Church was built, can he still be confident that he is in the Church?" Roman Catholicism holds that Christ entrusted the Apostles with the leadership of the community of believers, and the obligation to transmit and preserve the "deposit of faith" (the experience of Christ and his teachings contained in the doctrinal "tradition" handed down from the time of the apostles and the written portion, which is Scripture). The apostles then passed on this office and authority by ordaining bishops to follow after them. Roman Catholic theology holds that the apostolic succession effects the power and authority to administer the sacraments except for baptism and matrimony. (Baptism may be administered by anyone and matrimony by the couple to each other.) Authority to so administer such sacraments is passed on only through the sacrament of Holy Orders, a rite by which a priest is ordained (ordination can be conferred only by bishop). The bishop, of course, must be from an unbroken line of bishops stemming from the original apostles selected by Jesus Christ. Thus, apostolic succession is necessary for the valid celebration of the sacraments. Views concerning other churches In the Roman Catholic Church, Pope Leo XIII stated in his 1896 bull Apostolicae curae that the Catholic Church believes specifically that Anglican orders were to be considered "absolutely null and utterly void". His argument was as follows. First, the ordination rite of Edward VI had removed the language of a sacrificial priesthood. Ordinations using this new rite occurred for over a century and, because the restoration of the language of "priesthood" a century later in the ordination rite "was introduced too late, as a century had already elapsed since the adoption of the Edwardine Ordinal ... the Hierarchy had become extinct, there remained no power of ordaining." With this extinction of validly ordained bishops in England, "the true Sacrament of Order as instituted by Christ lapsed, and with it the hierarchical succession." As a result, the pope's final judgment was that Anglican ordinations going forward were to be considered "absolutely null and utterly void". Anglican clergy were from then on to be ordained as Roman Catholic priests upon entry into the Catholic Church. A reply from the Archbishops of Canterbury and York (1896) was issued to counter Pope Leo's arguments: Saepius officio: Answer of the Archbishops of Canterbury and York to the Bull Apostolicae Curae of H. H. Leo XIII. They argued that if the Anglican orders were invalid, then the Roman orders were as well since the Pope based his case on the fact that the Anglican ordinals used did not contain certain essential elements but these were not found in the early Roman rites either. Catholics argue, this argument does not consider the sacramental intention involved in validating Holy Orders. In other words, Roman Catholics believe that the ordination rites were reworded so as to invalidate the ordinations because the intention behind the alterations in the rite was a fundamental change in Anglican understanding of the priesthood. It is Roman Catholic doctrine that the teaching of Apostolicae curae is a truth to be "held definitively, but are not able to be declared as divinely revealed", as stated in a commentary by the Congregation for the Doctrine of the Faith. Cardinal Basil Hume explained the conditional character of his ordination of Graham Leonard, former Anglican bishop of the Diocese of London, to the priesthood in the following way: "While firmly restating the judgement of Apostolicae Curae that Anglican ordination is invalid, the Roman Catholic Church takes account of the involvement, in some Anglican episcopal ordinations, of bishops of the Old Catholic Church of the Union of Utrecht who are validly ordained. In particular and probably rare cases the authorities in Rome may judge that there is a 'prudent doubt' concerning the invalidity of priestly ordination received by an individual Anglican minister ordained in this line of succession." At the same time, he stated: "Since the church must be in no doubt of the validity of the sacraments celebrated for the Roman Catholic community, it must ask all who are chosen to exercise the priesthood in the Catholic Church to accept sacramental ordination in order to fulfill their ministry and be integrated into the apostolic succession." Since Apostolicae curae was issued many Anglican jurisdictions have revised their ordinals, bringing them more in line with ordinals of the early Church. Timothy Dufort, writing in The Tablet in 1982, attempted to present an ecumenical solution to the problem of how the Roman Catholic Church might accept Anglican orders without needing to formally repudiate Apostolicae curae at all. Dufort argued that by 1969 all Anglican bishops had acquired apostolic succession fully recognized by Rome, since from the 1930s Old Catholic bishops (the validity of whose orders the Vatican has never questioned) have acted as co-consecrators in the ordination of Anglican bishops. This view has not yet been considered formally by the Holy See, but after Anglican Bishop Graham Leonard converted to Roman Catholicism, he was only reordained in 1994 because of the presence of Old Catholic bishops at his ordination. The question of the validity of Anglican orders has been further complicated by the Anglican ordination of women. In a document it published in July 1998, the Congregation for the Doctrine of the Faith stated that the Catholic Church's declaration on the invalidity of Anglican ordinations is a teaching that the church has definitively propounded and that therefore every Roman Catholic is required to give "firm and definitive assent" to this matter. This being said, in May 2017, Cardinal Francesco Coccopalmerio, President of the Pontifical Council for Legislative Texts, has asked whether the current Roman Catholic position on invalidity could be revised in the future. Eastern Orthodox While Eastern Orthodox sources often refer to the bishops as "successors of the apostles" under the influence of Scholastic theology, strict Orthodox ecclesiology and theology hold that all legitimate bishops are properly successors of Peter. This also means that presbyters (or "priests") are successors of the apostles. As a result, Eastern Orthodox theology makes a distinction between a geographical or historical succession and proper ontological or ecclesiological succession. Hence, the bishops of Rome and Antioch can be considered successors of Peter in a historical sense on account of Peter's presence in the early community. This does not imply that these bishops are more successors of Peter than all others in an ontological sense. The Eastern Orthodox have often permitted non-Eastern Orthodox clergy to be rapidly ordained within Orthodoxy as a matter of pastoral necessity and economia. Priests entering Eastern Orthodoxy from Oriental Orthodoxy and Roman Catholicism have usually been received by "vesting" and have been allowed to function immediately within Eastern Orthodoxy as priests. Recognition of Roman Catholic orders by the Russian Orthodox Church was stipulated in 1667 by the Synod of Moscow, but this position is not universal within the Eastern Orthodox communion. For example, Fr. John Morris of the Antiochian Orthodox Christian Archdiocese of North America, states that "Apostolic Succession is not merely a historical pedigree, but also requires Apostolic Faith. This is because Apostolic Succession is not the private possession of a bishop, but is the attribute of a local Church. A bishop who goes in schism or is cast out of office due to heresy does not take his Apostolic Succession with him as a private possession." The validity of a priest's ordination is decided by each autocephalous Eastern Orthodox church. In 1922 the Eastern Orthodox Ecumenical Patriarch of Constantinople recognised Anglican orders as valid, holding that they carry "the same validity as the Roman, Old Catholic and Armenian churches possess". In the encyclical "From the Oecumenical Patriarch to the Presidents of the Particular Eastern Orthodox churches", Meletius IV of Constantinople, the Oecumenical Patriarch, wrote: "That the Orthodox theologians who have scientifically examined the question have almost unanimously come to the same conclusions and have declared themselves as accepting the validity of Anglican Orders." Following this declaration, in 1923, the Eastern Orthodox Patriarchate of Jerusalem, as well as the Eastern Orthodox Church of Cyprus agreed by "provisionally acceding that Anglican priests should not be re-ordained if they became Orthodox"; in 1936, the Romanian Orthodox Church "endorsed Anglican Orders". Succeeding judgements have been more conflicting. The Eastern Orthodox churches require a totality of common teaching to recognise orders and in this broader view find ambiguities in Anglican teaching and practice problematic. Accordingly, in some parts of the Eastern Orthodox Church, Anglican clergy who convert to Orthodoxy are reordained, rather than vested. Oriental Orthodox Churches The Armenian Apostolic Church, which is one of the Oriental Orthodox churches, recognises Roman Catholic episcopal consecrations without qualification. Anglican Communion The Anglican Communion "has never officially endorsed any one particular theory of the origin of the historic episcopate, its exact relation to the apostolate, and the sense in which it should be thought of as God given, and in fact tolerates a wide variety of views on these points". Its claim to apostolic succession is rooted in the Church of England's evolution as part of the Western Church. Apostolic succession is viewed not so much as conveyed mechanically through an unbroken chain of the laying-on of hands, but as expressing continuity with the unbroken chain of commitment, beliefs and mission starting with the first apostles; and as hence emphasising the enduring yet evolving nature of the Church. When Henry VIII broke away from the jurisdiction of Rome in 1533/4, the English Church () claimed the episcopal polity and apostolic succession inherent in its Roman Catholic past. Reformed theology gained a certain foothold, and under his successor, Edward VI what had been an administrative schism – as the Church under Henry was separated from Rome but remained essentially Roman Catholic in its theology and practice – became a reformation under the guiding hand of Thomas Cranmer. Although care was taken to maintain the unbroken sequence of episcopal consecrations – particularly in the case of Matthew Parker, who was consecrated Archbishop of Canterbury in 1559 by two bishops who had been ordained in the 1530s with the Roman Pontifical and two ordained with the Edwardine Ordinal of 1550 – apostolic succession was not seen as a major concern that a true ministry could not exist without episcopal consecrations: English Reformers such as Richard Hooker rejected the Roman position that Apostolic Succession is divinely commanded or necessary for true Christian ministry. American Episcopal theologian Richard A. Norris argues that the "foreign Reformed [Presbyterian] churches" were genuine ones despite the lack of apostolic succession because they had been abandoned by their bishops at the Reformation. In very different ways both James II and William III of England made it plain that the Church of England could no longer count on the 'godly prince' to maintain its identity and traditions and the 'High Church' clergy of the time began to look to the idea of apostolic succession as a basis for the church's life. For William Beveridge (Bishop of St Asaph, 1704–8) the importance of this lay in the fact that Christ himself is "continually present at such imposition of hands; thereby transferring the same Spirit, which He had first breathed into His Apostles, upon others successively after them", but the doctrine did not really come to the fore until the time of the Tractarians. In 1833, before his conversion to Roman Catholicism, Newman wrote about the apostolic succession: "We must necessarily consider none to be ordained who has not been ordained". After quoting this, Michael Ramsey continues: "With romantic enthusiasm, the Tractarians propagated this doctrine. In doing so they involved themselves in some misunderstandings of history and in some confusion of theology". He goes on to explain that they ascribed to early Anglican authors a far more exclusive version of the doctrine than was the case, they blurred the distinction between succession in office (Irenaeus) and succession in consecration (Augustine); they spoke of apostolic succession as the channel of grace in a way that failed to do justice to His gracious activity within all the dispensations of the New Covenant. J. B. Lightfoot argued that monarchial episcopacy evolved upwards from a college of presbyters by the elevation of one of their number to be the episcopal president and A.C. Headlam laid great stress on Irenaeus' understanding of succession which had been lost from sight behind the Augustinian 'pipe-line theory'. Lutheran churches Variation exists within Lutheranism on this issue. There are two primary camps: episcopal succession, and succession of presbyters. All Lutherans believe in some form of apostolic succession, per the Lutheran Confessions. The Lutheran churches in Scandinavia, the Caribbean, and elsewhere practice episcopal succession in which the bishop whose holy orders can be traced back for centuries performs ordinations. German Lutheran churches and their subsequent offspring in the United States practice succession of presbyters in which another priest is the one who confers the priesthood onto another. This low view results from the Prussian state-ordered union with Reformed (Calvinist) churches in 1817. Lutheran claims to apostolic succession In Scandinavia and the Baltic region, Lutheran churches participating in the Porvoo Communion (those of Iceland, Norway, Sweden, Finland, Estonia, and Lithuania), as well as non-Porvoo membership Lutheran churches in the region (including those of Latvia, and Russia), and the confessional Communion of Nordic Lutheran Dioceses, believe that they ordain their bishops in apostolic succession in lines stemming from the original apostles. The New Westminster Dictionary of Church History states that "In Sweden the apostolic succession was preserved because the Catholic bishops were allowed to stay in office, but they had to approve changes in the ceremonies." The Lutheran Church of Finland was at that time one with the Church of Sweden and so holds the same view regarding the see of Åbo/Turku. In 2001, Francis Aloysius Sullivan wrote: "To my knowledge, the Catholic Church has never officially expressed its judgement on the validity of orders as they have been handed down by episcopal succession in these two national Lutheran churches." In 2007, the Holy See declared: "Christian Communities born out of the Reformation of the sixteenth century [...] do not enjoy apostolic succession in the sacrament of Orders, and are, therefore, deprived of a constitutive element of the Church." This statement speaks of the Protestant movement as a whole, not specifically of the Lutheran churches in Sweden and Finland. The 2010 report from the Roman Catholic – Lutheran Dialogue Group for Sweden and Finland, Justification in the Life of the Church, states: "The Evangelical-Lutheran churches in Sweden and Finland [...] believe that they are part of an unbroken apostolic chain of succession. The Catholic Church does however question how the ecclesiastical break in the 16th century has affected the apostolicity of the churches of the Reformation and thus the apostolicity of their ministry." Emil Anton interprets this report as saying that the Roman Catholic Church does not deny or approve the apostolic succession directly, but will continue with further inquiries about the matter. Negotiated at Järvenpää, Finland, and inaugurated with a celebration of the Eucharist at Porvoo Cathedral in 1992, the Porvoo Communion agreement of unity includes the mutual recognition of the traditional apostolic succession among the following churches: Lutheran churches: Evangelical Lutheran Church of Iceland, Church of Norway, Church of Sweden, Evangelical Lutheran Church of Finland, Estonian Evangelical Lutheran Church, Evangelical Lutheran Church of Lithuania, Church of Denmark, The Lutheran Church in Great Britain observer: Evangelical Lutheran Church of Latvia. Anglican Communion: Church of Ireland, Scottish Episcopal Church, Church of England, the Church in Wales, the Lusitanian Catholic Apostolic Evangelical Church, and the Spanish Reformed Episcopal Church. At least one of the Scandinavian Lutheran churches in the Porvoo Communion of churches, the Church of Denmark has bishops, but strictly speaking they were not in the historic apostolic succession prior to their entry into the Porvoo Communion, since their episcopate and holy orders derived from Johannes Bugenhagen, who was a pastor, not a bishop. In 2010, the Church of Denmark joined the Porvoo Communion of churches, after a process of mutual consecrations of bishops had led to the introduction of historic apostolic succession. The Lutheran Church in Great Britain also joined the Porvoo Agreement, in 2014. In Scandinavia, where High Church Lutheranism and Pietist Lutheranism has been highly influential, the Evangelical Lutheran Mission Diocese of Finland, Mission Province of the Church of Sweden, and the Evangelical Lutheran Diocese of Norway entered into schism with their national churches due to "the secularization of the national/state churches in their respective countries involving matters of both Christian doctrine and ethics"; these have altar and pulpit fellowship through the Communion of Nordic Lutheran Dioceses and are members of the confessional International Lutheran Council with their bishops having lines of apostolic succession from other traditional Lutheran Churches, such as the Evangelical Lutheran Church in Kenya. Similarly, in the High Church Lutheranism of Germany, some religious brotherhoods such as Hochkirchliche St. Johannes-Bruderschaft and Hochkirchlicher Apostolat St. Ansgar have managed to arrange for their own bishop to be re-ordained in apostolic succession. The members of these brotherhoods do not form into separate ecclesia. The Evangelical Lutheran Church in America, North America's largest Lutheran body, gained apostolic succession through Lutheran bishops in the historic episcopate; this allowed for full communion with the Episcopal Church in 2000, upon the signing of Called to Common Mission. By this document the full communion between the Evangelical Lutheran Church in America and the Episcopal Church was established. As such, "all episcopal installations in the Evangelical Lutheran Church in America take place with the participation of bishops in the apostolic succession." The Evangelical Lutheran Church in America is headed by a presiding bishop who is elected by the churchwide assembly for a six-year term. The Evangelical Catholic Church, a Lutheran denomination of Evangelical Catholic churchmanship based in North America, taught: In recent years a number of Lutheran churches of the Evangelical Catholic and High Church Lutheran churchmanship in the United States of America have accepted the doctrine of apostolic succession and have successfully recovered it, generally from Independent Catholic churches. At present, most of these church bodies have memberships numbering in the hundreds. The Lutheran Evangelical Protestant Church (LEPC) were some of the earliest Lutherans in America. They have autonomous and congregationally oriented ministries and consecrate male and female deacons, priests and bishops in apostolic succession with the laying on of hands during celebration of Word and Sacrament. The Anglo-Lutheran Catholic Church recovered the apostolic succession from Old Catholic and Independent Catholic churches, and adopted a strict episcopal polity. All of its clergy have been ordained (or re-ordained) into the historic apostolic succession. This Church was formed in 1997, with its headquarters in Kansas City, Missouri. The Lutheran Orthodox Church, founded in 2004 traces its historic lineage of apostolic succession through Anglican, Lutheran, and Old Catholic lines. The Lutheran Church - International is another North American Lutheran church which reports that it has recovered the historic apostolic succession. Indifference to the issue Many German Lutherans appear to demur on this issue, which may be sourced in the church governance views of Martin Luther. Luther's reform movement usually did not abrogate the ecclesiastic office of bishop. An important historical context to explicate the wide differences among German Lutheran churches is the Prussian Union of 1817, whereby the secular government directed the Lutheran churches in Prussia to merge with non-Lutheran Reformed churches in Prussia. The Reformed churches generally oppose on principle the traditional doctrine of ecclesiastic Apostolic Succession, e.g., not usually even recognising the church office of bishop. Later in the 19th century, other Lutheran and Reformed congregations merged to form united church bodies in some of the other 39 states of the German Confederation, e.g., in Anhalt, Baden, Bremen, Hesse and Nassau, Hesse-Kassel and Waldeck, and the Palatinate. Yet the partial nature of this list also serves to show that in Germany there remained many Lutherans who never united with the Reformed. Other Lutheran churches are indifferent as a matter of doctrine regarding this particular issue of ecclesiastical governance. In America, the conservative Lutheran Church–Missouri Synod (LCMS) places its church authority in the congregation rather than in the bishop, and ordinations are typically performed by another pastor, although its founder, C. F. W. Walther, while establishing congregational polity for the LCMS, considered polity (a church's form of government) to be a matter of adiaphora (something indifferent). Methodist churches In the beginnings of the Methodist movement, adherents were instructed to receive the sacraments within the Anglican Church since the Methodists were still a movement and not as yet a separate church in England until 1805. The American Methodists soon petitioned to receive the sacraments from the local preachers who conducted worship services and revivals. The Bishop of London refused to ordain Methodist priests and deacons in the British American colonies. John Wesley, the founder of the movement, was reluctant to allow unordained preachers to administer the sacraments: Some scholars argue that in 1763, Greek Orthodox bishop Erasmus of the Diocese of Arcadia, who was visiting London at the time, consecrated John Wesley a bishop, and ordained several Methodist lay preachers as priests, including John Jones. According to these arguments, Wesley could not openly announce his episcopal consecration without incurring the penalty of the Præmunire Act. In light of Wesley's alleged episcopal consecration, the Methodist Church could lay claim on apostolic succession, as understood in the traditional sense. Since John Wesley "ordained and sent forth every Methodist preacher in his day, who preached and baptized and ordained, and since every Methodist preacher who has ever been ordained as a Methodist was ordained in this direct 'succession' from Wesley, then the Methodist Church teaches that it has all the direct merits coming from apostolic succession, if any such there be." Most Methodists view apostolic succession outside its high church sense. This is because Wesley believed that the offices of bishop and presbyter constituted one order, citing an ancient opinion from the Church of Alexandria; Jerome, a Church Father, wrote: "For even at Alexandria from the time of Mark the Evangelist until the episcopates of Heraclas and Dionysius the presbyters always named as bishop one of their own number chosen by themselves and set in a more exalted position, just as an army elects a general, or as deacons appoint one of themselves whom they know to be diligent and call him archdeacon. For what function, excepting ordination, belongs to a bishop that does not also belong to a presbyter?" (Letter CXLVI). John Wesley thus argued that for two centuries the succession of bishops in the Church of Alexandria, which was founded by Mark the Evangelist, was preserved through ordination by presbyters alone and was considered valid by that ancient Church. Since the Bishop of London refused to ordain ministers in the British American colonies, this constituted an emergency and as a result, on 2 September 1784, Wesley, along with a priest from the Anglican Church and two other elders, operating under the ancient Alexandrian habitude, ordained Thomas Coke a superintendent, although Coke embraced the title bishop. Today, the United Methodist Church follows this ancient Alexandrian practice as bishops are elected from the presbyterate: the Discipline of the Methodist Church, in ¶303, affirms that "ordination to this ministry is a gift from God to the Church. In ordination, the Church affirms and continues the apostolic ministry through persons empowered by the Holy Spirit." It also uses sacred scripture in support of this practice, namely, 1 Timothy 4:14, which states: The Methodist Church also buttresses this argument with the leg of sacred tradition of the Wesleyan Quadrilateral by citing the Church Fathers, many of whom concur with this view. In addition to the aforementioned arguments – or perhaps instead of them – in 1937 the annual Conference of the British Methodist Church located the "true continuity" with the Church of past ages in "the continuity of Christian experience, the fellowship in the gift of the one Spirit; in the continuity in the allegiance to one Lord, the continued proclamation of the message; the continued acceptance of the mission;..." [through a long chain which goes back to] "the first disciples in the company of the Lord Himself ... This is our doctrine of apostolic succession" [which neither depends on, nor is secured by,] "an official succession of ministers, whether bishops or presbyters, from apostolic times, but rather by fidelity to apostolic truth". The Church of North India, Church of Pakistan and Church of South India are members of the World Methodist Council and the clergy of these three united Protestant churches possess lines of apostolic succession, according to the Anglican understanding of this doctrine, through the Church of India, Burma and Ceylon (CIBC), which finished merging with these three in the 1970s. In June 2014, the Church of Ireland, a province of the Anglican Communion, extended its lines of apostolic succession into the Methodist Church in Ireland, as "the Archbishop of Dublin and Bishop of Down and Dromore took part in the installation of the new President of the Methodist Church of Ireland, the Rev. Peter Murray." In May 2014, the "Church of Ireland's General Synod approved an agreement signed with the Methodist Church that provided for the interchangeability of clergy, allowing an ordained minister of either church to come under the discipline and oversight of the other." Hussite Church and Moravian Church The Moravian Church, as with the Hussite Church, teaches the doctrine of apostolic succession. The Moravian Church claims apostolic succession as a legacy of the old Unity of the Brethren. In order to preserve the succession, three Bohemian Brethren were consecrated bishops by Bishop Stephen of Austria, a Waldensian bishop who had been ordained by a Roman Catholic bishop in 1434. These three consecrated bishops returned to Litice in Bohemia and then ordained other brothers, thereby preserving the historic episcopate. Presbyterian/Reformed churches Jus Divinum Regiminis Ecclesiastici (English translation: The Divine Right of Church Government), which was promulgated by Presbyterian clergy in 1646, holds that historic ministerial succession is necessary for legitimate ministerial authority. It states that ministerial succession is conferred by elders through the laying on of hands, in accordance with Timothy 4:14. The Westminster Assembly held that "There is one general church visible" and that "every minister of the word is to be ordained by imposition of hands, and prayer, with fasting, by those preaching presbyters to whom it doth belong". The Church of North India, Church of Pakistan and Church of South India are members of the World Alliance of Reformed Churches and the clergy of these three united Protestant churches possess lines of apostolic succession, according to the Anglican understanding of this doctrine, through the Church of India, Burma and Ceylon (CIBC), which finished merging with these three in the 1970s. Pentecostal churches On 6 February 2003, Rt. the Rev. Dr. K. J. Samuel, the Moderator Bishop of the Church of South India (a United Protestant denomination that holds membership worldwide Anglican Communion in addition to the World Communion of Reformed Churches), along with the Rt. Rev. P.M. Dhotekar, Bishop of Nagpur of the Church of North India, and the Rt. Rev. Bancha Nidhi Nayak, Bishop of Phulbani of the Church of North India, consecrated Pentecostal minister K. P. Yohannan as a bishop in Anglican lines of apostolic succession; the Rt. Rev. K.P. Yohannan thereafter became the first Metropolitan of the Believers Eastern Church, a Pentecostal denomination which acquired an episcopal polity of ecclesiastical governance. Many other Pentecostal Christians teach that "the sole guarantor of apostolic faith, which includes apostolic life, is the Holy Spirit." In addressing the Church of God General Assembly, Ambrose Jessup Tomlinson stated that "Although we do not claim a line of succession from the holy apostles, we do believe we are following in their example." Latter Day Saint movement Denominations within the Latter Day Saint movement preach the necessity of apostolic succession and claim it through the process of restoration. According to their teaching, a period of universal apostasy followed the death of the Twelve Apostles. Without apostles or prophets left on the earth with the legitimate Priesthood Authority, many of the true teachings and practices of Christianity were lost. Eventually these were restored to the prophet Joseph Smith and various others in a series of divine conferrals and ordinations by angelic men who had held this authority during their lifetimes (see this partial list of restoration events). As it relates to apostolic succession, Joseph Smith and Oliver Cowdery said that the apostles Peter, James, and John appeared to them in 1829 and conferred upon them the Melchizedek Priesthood and with it "the keys of the kingdom, and of the dispensation of the fullness of times". For the Church of Jesus Christ of Latter-day Saints (LDS Church), the largest denomination in the Latter-day Saint movement, Apostolic Succession involves the leadership of the church being established through the Quorum of the Twelve Apostles. Each time the President of the Church dies, the most senior apostle, who is designated as the President of the Quorum of the Twelve Apostles, is set apart as the new church president. Denominations that reject apostolic succession Some Nonconformist Protestants, particularly those in the Calvinist tradition, deny the doctrine of apostolic succession, believing that it is neither taught in Scripture nor necessary for Christian teaching, life, and practice. Accordingly, these Protestants strip the notion of apostolic succession from the definition of "apostolic" or "apostolicity". For them, to be apostolic is simply to be in submission to the teachings of the original twelve apostles as recorded in Scripture. This doctrinal stance reflects the Protestant view of authority, embodied in the doctrine known as Sola Scriptura. Among the first who rejected the doctrine of apostolic succession were John Calvin, and Martin Luther. They both said that the episcopacy was inadequate to address corruption, doctrinal or otherwise, and that this inadequacy justified the intervention of the church of common people. In part this position was also necessary, as otherwise there would have been no means to elicit or initiate reform of the church. In the 20th century, there has been more contact between Protestants and Christians from Eastern traditions which claim apostolic succession for their ministry. Like the Roman Catholic Church, these ancient Eastern churches may use the doctrine of apostolic succession in ministry in their apologetics against some forms of Protestantism. Some Protestants feel that such claims of apostolic succession are proven false by the differences in traditions and doctrines between these churches: Roman Catholics and Eastern Orthodox consider both the Church of the East and the Oriental Orthodox churches to be heretical, having been anathematized in the early ecumenical councils of Ephesus (431) and Chalcedon (451) respectively. Churches that claim apostolic succession in ministry distinguish this from doctrinal orthodoxy, holding that "it is possible to have valid orders coming down from the apostles, and yet not to have a continuous spiritual history coming down from the apostles". All Christians who have a genuine relationship with God through and in Christ are part of the "true Church", according to exemplary statements of evangelical Protestant theology, notwithstanding condemnation of the Catholic Church by some Protestants. According to these statements, claims that one or more denominations might be the "true Church" are nothing more than propaganda which has evolved over centuries to support authoritarian claims – based on tradition or based on scripture – of merely human institutions. Such claims can be found among the worldwide community of Christians. Yet all appear to treasure the truth that liberates, and Jesus taught his followers to love one another.

Sir Arthur Stanley Eddington (28 December 1882 – 22 November 1944) was an English astronomer, physicist, and mathematician. He was also a philosopher of science and a populariser of science. The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour. Around 1920, he foreshadowed the discovery and mechanism of nuclear fusion processes in stars, in his paper "The Internal Constitution of the Stars". At that time, the source of stellar energy was a complete mystery; Eddington was the first to correctly speculate that the source was fusion of hydrogen into helium. Eddington wrote a number of articles that announced and explained Einstein's theory of general relativity to the English-speaking world. World War I had severed many lines of scientific communication, and new developments in German science were not well known in England. He also conducted an expedition to observe the solar eclipse of 29 May 1919 on the Island of Principe that provided one of the earliest confirmations of general relativity, and he became known for his popular expositions and interpretations of the theory. Early years Eddington was born 28 December 1882 in Kendal, Westmorland (now Cumbria), England, the son of Quaker parents, Arthur Henry Eddington, headmaster of the Quaker School, and Sarah Ann Shout. His father taught at a Quaker training college in Lancashire before moving to Kendal to become headmaster of Stramongate School. He died in the typhoid epidemic which swept England in 1884. His mother was left to bring up her two children with relatively little income. The family moved to Weston-super-Mare where at first Stanley (as his mother and sister always called Eddington) was educated at home before spending three years at a preparatory school. The family lived at a house called Varzin, 42 Walliscote Road, Weston-super-Mare. There is a commemorative plaque on the building explaining Sir Arthur's contribution to science. In 1893 Eddington entered Brynmelyn School. He proved to be a most capable scholar, particularly in mathematics and English literature. His performance earned him a scholarship to Owens College, Manchester (what was later to become the University of Manchester), in 1898, which he was able to attend, having turned 16 that year. He spent the first year in a general course, but he turned to physics for the next three years. Eddington was greatly influenced by his physics and mathematics teachers, Arthur Schuster and Horace Lamb. At Manchester, Eddington lived at Dalton Hall, where he came under the lasting influence of the Quaker mathematician J. W. Graham. His progress was rapid, winning him several scholarships and he graduated with a BSc in physics with First Class Honours in 1902. Based on his performance at Owens College, he was awarded a scholarship to Trinity College, Cambridge, in 1902. His tutor at Cambridge was Robert Alfred Herman and in 1904 Eddington became the first ever second-year student to be placed as Senior Wrangler. After receiving his M.A. in 1905, he began research on thermionic emission in the Cavendish Laboratory. This did not go well, and meanwhile he spent time teaching mathematics to first year engineering students. This hiatus was brief. Through a recommendation by E. T. Whittaker, his senior colleague at Trinity College, he secured a position at the Royal Observatory, Greenwich, where he was to embark on his career in astronomy, a career whose seeds had been sown even as a young child when he would often "try to count the stars". Astronomy In January 1906, Eddington was nominated to the post of chief assistant to the Astronomer Royal at the Royal Greenwich Observatory. He left Cambridge for Greenwich the following month. He was put to work on a detailed analysis of the parallax of 433 Eros on photographic plates that had started in 1900. He developed a new statistical method based on the apparent drift of two background stars, winning him the Smith's Prize in 1907. The prize won him a fellowship of Trinity College, Cambridge. In December 1912, George Darwin, son of Charles Darwin, died suddenly, and Eddington was promoted to his chair as the Plumian Professor of Astronomy and Experimental Philosophy in early 1913. Later that year, Robert Ball, holder of the theoretical Lowndean chair, also died, and Eddington was named the director of the entire Cambridge Observatory the next year. In May 1914, he was elected a fellow of the Royal Society: he was awarded the Royal Medal in 1928 and delivered the Bakerian Lecture in 1926. Eddington also investigated the interior of stars through theory, and developed the first true understanding of stellar processes. He began this in 1916 with investigations of possible physical explanations for Cepheid variable stars. He began by extending Karl Schwarzschild's earlier work on radiation pressure in Emden polytropic models. These models treated a star as a sphere of gas held up against gravity by internal thermal pressure, and one of Eddington's chief additions was to show that radiation pressure was necessary to prevent collapse of the sphere. He developed his model despite knowingly lacking firm foundations for understanding opacity and energy generation in the stellar interior. However, his results allowed for calculation of temperature, density and pressure at all points inside a star (thermodynamic anisotropy), and Eddington argued that his theory was so useful for further astrophysical investigation that it should be retained despite not being based on completely accepted physics. James Jeans contributed the important suggestion that stellar matter would certainly be ionized, but that was the end of any collaboration between the pair, who became famous for their lively debates. Eddington defended his method by pointing to the utility of his results, particularly his important mass–luminosity relation. This had the unexpected result of showing that virtually all stars, including giants and dwarfs, behaved as ideal gases. In the process of developing his stellar models, he sought to overturn current thinking about the sources of stellar energy. Jeans and others defended the Kelvin–Helmholtz mechanism, which was based on classical mechanics, while Eddington speculated broadly about the qualitative and quantitative consequences of possible proton–electron annihilation and nuclear fusion processes. Around 1920, he anticipated the discovery and mechanism of nuclear fusion processes in stars, in his paper "The Internal Constitution of the Stars". At that time, the source of stellar energy was a complete mystery; Eddington correctly speculated that the source was fusion of hydrogen into helium, liberating enormous energy according to Einstein's equation . This was a particularly remarkable development since at that time fusion and thermonuclear energy, and even the fact that stars are largely composed of hydrogen (see metallicity), had not yet been discovered. Eddington's paper, based on knowledge at the time, reasoned that: The leading theory of stellar energy, the contraction hypothesis (cf. the Kelvin–Helmholtz mechanism), should cause stars' rotation to visibly speed up due to conservation of angular momentum. But observations of Cepheid variable stars showed this was not happening. The only other known plausible source of energy was conversion of matter to energy; Einstein had shown some years earlier that a small amount of matter was equivalent to a large amount of energy. Francis Aston had also recently shown that the mass of a helium atom was about 0.8% less than the mass of the four hydrogen atoms which would, combined, form a helium atom, suggesting that if such a combination could happen, it would release considerable energy as a byproduct. If a star contained just 5% of fusible hydrogen, it would suffice to explain how stars got their energy. (We now know that most "ordinary" stars contain far more than 5% hydrogen.) Further elements might also be fused, and other scientists had speculated that stars were the "crucible" in which light elements combined to create heavy elements, but without more accurate measurements of their atomic masses nothing more could be said at the time. All of these speculations were proven correct in the following decades. With these assumptions, he demonstrated that the interior temperature of stars must be millions of degrees. In 1924, he discovered the mass–luminosity relation for stars (see Lecchini in ). Despite some disagreement, Eddington's models were eventually accepted as a powerful tool for further investigation, particularly in issues of stellar evolution. The confirmation of his estimated stellar diameters by Michelson in 1920 proved crucial in convincing astronomers unused to Eddington's intuitive, exploratory style. Eddington's theory appeared in mature form in 1926 as The Internal Constitution of the Stars, which became an important text for training an entire generation of astrophysicists. Eddington's work in astrophysics in the late 1920s and the 1930s continued his work in stellar structure, and precipitated further clashes with Jeans and Edward Arthur Milne. An important topic was the extension of his models to take advantage of developments in quantum physics, including the use of degeneracy physics in describing dwarf stars. Dispute with Chandrasekhar on the mass limit of stars The topic of extension of his models precipitated his dispute with Subrahmanyan Chandrasekhar, who was then a student at Cambridge. Chandrasekhar's work presaged the discovery of black holes, which at the time seemed so absurdly non-physical that Eddington refused to believe that Chandrasekhar's purely mathematical derivation had consequences for the real world. Eddington was wrong and his motivation is controversial. Chandrasekhar's narrative of this incident, in which his work is harshly rejected, portrays Eddington as rather cruel and dogmatic. Chandra benefited from his friendship with Eddington. It was Eddington and Milne who put up Chandra's name for the fellowship for the Royal Society which Chandra obtained. An FRS meant he was at the Cambridge high-table with all the luminaries and a very comfortable endowment for research. Eddington's criticism seems to have been based partly on a suspicion that a purely mathematical derivation from relativity theory was not enough to explain the seemingly daunting physical paradoxes that were inherent to degenerate stars, but to have "raised irrelevant objections" in addition, as Thanu Padmanabhan puts it. Relativity During World War I, Eddington was secretary of the Royal Astronomical Society, which meant he was the first to receive a series of letters and papers from Willem de Sitter regarding Einstein's theory of general relativity. Eddington was fortunate in being not only one of the few astronomers with the mathematical skills to understand general relativity, but owing to his internationalist and pacifist views inspired by his Quaker religious beliefs, one of the few at the time who was still interested in pursuing a theory developed by a German physicist. He quickly became the chief supporter and expositor of relativity in Britain. He and Astronomer Royal Frank Watson Dyson organized two expeditions to observe a solar eclipse in 1919 to make the first empirical test of Einstein's theory: the measurement of the deflection of light by the Sun's gravitational field. In fact, Dyson's argument for the indispensability of Eddington's expertise in this test was what prevented Eddington from eventually having to enter military service. When conscription was introduced in Britain on 2 March 1916, Eddington intended to apply for an exemption as a conscientious objector. Cambridge University authorities instead requested and were granted an exemption on the ground of Eddington's work being of national interest. In 1918, this was appealed against by the Ministry of National Service. Before the appeal tribunal in June, Eddington claimed conscientious objector status, which was not recognized and would have ended his exemption in August 1918. A further two hearings took place in June and July, respectively. Eddington's personal statement at the June hearing about his objection to war based on religious grounds is on record. The Astronomer Royal, Sir Frank Dyson, supported Eddington at the July hearing with a written statement, emphasising Eddington's essential role in the solar eclipse expedition to Príncipe in May 1919. Eddington made clear his willingness to serve in the Friends' Ambulance Unit, under the jurisdiction of the British Red Cross, or as a harvest labourer. However, the tribunal's decision to grant a further twelve months' exemption from military service was on condition of Eddington continuing his astronomy work, in particular in preparation for the Príncipe expedition. The war ended before the end of his exemption. After the war, Eddington travelled to the island of Príncipe off the west coast of Africa to watch the solar eclipse of 29 May 1919. During the eclipse, he took pictures of the stars (several stars in the Hyades cluster, including Kappa Tauri of the constellation Taurus) whose line of sight from the Earth happened to be near the Sun's location in the sky at that time of year. This effect is noticeable only during a total solar eclipse when the sky is dark enough to see stars which are normally obscured by the Sun's brightness. According to the theory of general relativity, stars with light rays that passed near the Sun would appear to have been slightly shifted because their light had been curved by its gravitational field. Eddington showed that Newtonian gravitation could be interpreted to predict half the shift predicted by Einstein. Eddington's observations published the next year allegedly confirmed Einstein's theory, and were hailed at the time as evidence of general relativity over the Newtonian model. The news was reported in newspapers all over the world as a major story. Afterward, Eddington embarked on a campaign to popularize relativity and the expedition as landmarks both in scientific development and international scientific relations. It has been claimed that Eddington's observations were of poor quality, and he had unjustly discounted simultaneous observations at Sobral, Brazil, which appeared closer to the Newtonian model, but a 1979 re-analysis with modern measuring equipment and contemporary software validated Eddington's results and conclusions. The quality of the 1919 results was indeed poor compared to later observations, but was sufficient to persuade contemporary astronomers. The rejection of the results from the expedition to Brazil was due to a defect in the telescopes used which, again, was completely accepted and well understood by contemporary astronomers. Throughout this period, Eddington lectured on relativity, and was particularly well known for his ability to explain the concepts in lay terms as well as scientific. He collected many of these into the Mathematical Theory of Relativity in 1923, which Albert Einstein suggested was "the finest presentation of the subject in any language." He was an early advocate of Einstein's general relativity, and an interesting anecdote well illustrates his humour and personal intellectual investment: Ludwik Silberstein, a physicist who thought of himself as an expert on relativity, approached Eddington at the Royal Society's (6 November) 1919 meeting where he had defended Einstein's relativity with his Brazil-Príncipe solar eclipse calculations with some degree of scepticism, and ruefully charged Arthur as one who claimed to be one of three men who actually understood the theory (Silberstein, of course, was including himself and Einstein as the other). When Eddington refrained from replying, he insisted Arthur not be "so shy", whereupon Eddington replied, "Oh, no! I was wondering who the third one might be!" Cosmology Eddington was also heavily involved with the development of the first generation of general relativistic cosmological models. He had been investigating the instability of the Einstein universe when he learned of both Lemaître's 1927 paper postulating an expanding or contracting universe and Hubble's work on the recession of the spiral nebulae. He felt the cosmological constant must have played the crucial role in the universe's evolution from an Einsteinian steady state to its current expanding state, and most of his cosmological investigations focused on the constant's significance and characteristics. In The Mathematical Theory of Relativity, Eddington interpreted the cosmological constant to mean that the universe is "self-gauging". Fundamental theory and the Eddington number During the 1920s until his death, Eddington increasingly concentrated on what he called "fundamental theory" which was intended to be a unification of quantum theory, relativity, cosmology, and gravitation. At first he progressed along "traditional" lines, but turned increasingly to an almost numerological analysis of the dimensionless ratios of fundamental constants. His basic approach was to combine several fundamental constants in order to produce a dimensionless number. In many cases these would result in numbers close to 1040, its square, or its square root. He was convinced that the mass of the proton and the charge of the electron were a "natural and complete specification for constructing a Universe" and that their values were not accidental. One of the discoverers of quantum mechanics, Paul Dirac, also pursued this line of investigation, which has become known as the Dirac large numbers hypothesis. A somewhat damaging statement in his defence of these concepts involved the fine-structure constant, α. At the time it was measured to be very close to 1/136, and he argued that the value should in fact be exactly 1/136 for epistemological reasons. Later measurements placed the value much closer to 1/137, at which point he switched his line of reasoning to argue that one more should be added to the degrees of freedom, so that the value should in fact be exactly 1/137, the Eddington number. Wags at the time started calling him "Arthur Adding-one". This change of stance detracted from Eddington's credibility in the physics community. The current CODATA value is 1/ Eddington believed he had identified an algebraic basis for fundamental physics, which he termed "E-numbers" (representing a certain group – a Clifford algebra). These in effect incorporated spacetime into a higher-dimensional structure. While his theory has long been neglected by the general physics community, similar algebraic notions underlie many modern attempts at a grand unified theory. Moreover, Eddington's emphasis on the values of the fundamental constants, and specifically upon dimensionless numbers derived from them, is nowadays a central concern of physics. In particular, he predicted a number of hydrogen atoms in the Universe 136 × 2256 ≈ 1.57 1079, or equivalently the half of the total number of particles protons + electrons. He did not complete this line of research before his death in 1944; his book Fundamental Theory was published posthumously in 1948. Eddington number for cycling Eddington is credited with devising a measure of a cyclist's long-distance riding achievements. The Eddington number in the context of cycling is defined as the maximum number E such that the cyclist has cycled at least E miles on at least E days. For example, an Eddington number of 70 would imply that the cyclist has cycled at least 70 miles in a day on at least 70 occasions. Achieving a high Eddington number is difficult, since moving from, say, 70 to 75 will (probably) require more than five new long-distance rides, since any rides shorter than 75 miles will no longer be included in the reckoning. Eddington's own life-time E-number was 84. The Eddington number for cycling is analogous to the h-index that quantifies both the actual scientific productivity and the apparent scientific impact of a scientist. Philosophy Idealism Eddington wrote in his book The Nature of the Physical World that "The stuff of the world is mind-stuff." The idealist conclusion was not integral to his epistemology but was based on two main arguments. The first derives directly from current physical theory. Briefly, mechanical theories of the ether and of the behaviour of fundamental particles have been discarded in both relativity and quantum physics. From this, Eddington inferred that a materialistic metaphysics was outmoded and that, in consequence, since the disjunction of materialism or idealism are assumed to be exhaustive, an idealistic metaphysics is required. The second, and more interesting argument, was based on Eddington's epistemology, and may be regarded as consisting of two parts. First, all we know of the objective world is its structure, and the structure of the objective world is precisely mirrored in our own consciousness. We therefore have no reason to doubt that the objective world too is "mind-stuff". Dualistic metaphysics, then, cannot be evidentially supported. But, second, not only can we not know that the objective world is nonmentalistic, we also cannot intelligibly suppose that it could be material. To conceive of a dualism entails attributing material properties to the objective world. However, this presupposes that we could observe that the objective world has material properties. But this is absurd, for whatever is observed must ultimately be the content of our own consciousness, and consequently, nonmaterial. Eddington believed that physics cannot explain consciousness - "light waves are propagated from the table to the eye; chemical changes occur in the retina; propagation of some kind occurs in the optic nerves; atomic changes follow in the brain. Just where the final leap into consciousness occurs is not clear. We do not know the last stage of the message in the physical world before it became a sensation in consciousness". Ian Barbour, in his book Issues in Science and Religion (1966), p. 133, cites Eddington's The Nature of the Physical World (1928) for a text that argues the Heisenberg Uncertainty Principles provides a scientific basis for "the defense of the idea of human freedom" and his Science and the Unseen World (1929) for support of philosophical idealism "the thesis that reality is basically mental". Charles De Koninck points out that Eddington believed in objective reality existing apart from our minds, but was using the phrase "mind-stuff" to highlight the inherent intelligibility of the world: that our minds and the physical world are made of the same "stuff" and that our minds are the inescapable connection to the world. As De Koninck quotes Eddington, Indeterminism Against Albert Einstein and others who advocated determinism, indeterminism—championed by Eddington—says that a physical object has an ontologically undetermined component that is not due to the epistemological limitations of physicists' understanding. The uncertainty principle in quantum mechanics, then, would not necessarily be due to hidden variables but to an indeterminism in nature itself. Eddington proclaimed "It is a consequence of the advent of the quantum theory that physics is no longer pledged to a scheme of deterministic law". Popular and philosophical writings Eddington wrote a parody of The Rubaiyat of Omar Khayyam, recounting his 1919 solar eclipse experiment. It contained the following quatrain: During the 1920s and 30s, Eddington gave numerous lectures, interviews, and radio broadcasts on relativity, in addition to his textbook The Mathematical Theory of Relativity, and later, quantum mechanics. Many of these were gathered into books, including The Nature of the Physical World and New Pathways in Science. His use of literary allusions and humour helped make these difficult subjects more accessible. Eddington's books and lectures were immensely popular with the public, not only because of his clear exposition, but also for his willingness to discuss the philosophical and religious implications of the new physics. He argued for a deeply rooted philosophical harmony between scientific investigation and religious mysticism, and also that the positivist nature of relativity and quantum physics provided new room for personal religious experience and free will. Unlike many other spiritual scientists, he rejected the idea that science could provide proof of religious propositions. His popular writings made him a household name in Great Britain between the world wars. Death Eddington died of cancer in the Evelyn Nursing Home, Cambridge, on 22 November 1944. He was unmarried. His body was cremated at Cambridge Crematorium (Cambridgeshire) on 27 November 1944; the cremated remains were buried in the grave of his mother in the Ascension Parish Burial Ground in Cambridge. Cambridge University's North West Cambridge development has been named Eddington in his honour. Eddington was played by David Tennant in the television film Einstein and Eddington, with Einstein played by Andy Serkis. The film was notable for its groundbreaking portrayal of Eddington as a somewhat repressed gay man. It was first broadcast in 2008. The actor Paul Eddington was a relative, mentioning in his autobiography (in light of his own weakness in mathematics) "what I then felt to be the misfortune" of being related to "one of the foremost physicists in the world".

The Apple II (stylized as ) is an 8-bit home computer and one of the world's first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak; Jerry Manock developed the design of Apple II's foam-molded plastic case, Rod Holt developed the switching power supply, while Steve Jobs's role in the design of the computer was limited to overseeing Jerry Manock's work on the plastic case. It was introduced by Jobs and Wozniak at the 1977 West Coast Computer Faire, and marks Apple's first launch of a personal computer aimed at a consumer market—branded toward American households rather than businessmen or computer hobbyists. Byte magazine referred to the Apple II, Commodore PET 2001, and TRS-80 as the "1977 Trinity". As the Apple II had the defining feature of being able to display color graphics, the Apple logo was redesigned to have a spectrum of colors. The Apple II is the first model in the Apple II series, followed by Apple II+, Apple IIe, Apple IIc, Apple IIc Plus, and the 16-bit Apple IIGS—all of which remained compatible. Production of the last available model, Apple IIe, ceased in November 1993. History By 1976, Steve Jobs had convinced product designer Jerry Manock (who had formerly worked at Hewlett Packard designing calculators) to create the "shell" for the Apple II—a smooth case inspired by kitchen appliances that concealed the internal mechanics. The earliest Apple II computers were assembled in Silicon Valley and later in Texas; printed circuit boards were manufactured in Ireland and Singapore. The first computers went on sale on June 10, 1977 with an MOS Technology 6502 microprocessor running at 1.023 MHz ( of the NTSC color subcarrier), two game paddles (bundled until 1980, when they were found to violate FCC regulations), 4 KiB of RAM, an audio cassette interface for loading programs and storing data, and the Integer BASIC programming language built into ROMs. The video controller displayed 24 lines by 40 columns of monochrome, uppercase-only text on the screen (the original character set matches ASCII characters 20h to 5Fh), with NTSC composite video output suitable for display on a TV monitor or on a regular TV set (by way of a separate RF modulator). The original retail price of the computer with 4 KiB of RAM was and with the maximum 48 KiB of RAM it was To reflect the computer's color graphics capability, the Apple logo on the casing has rainbow stripes, which remained a part of Apple's corporate logo until early 1998. Perhaps most significantly, the Apple II was a catalyst for personal computers across many industries; it opened the doors to software marketed at consumers. Certain aspects of the system's design were influenced by Atari's arcade video game Breakout (1976), which was designed by Wozniak, who said: "A lot of features of the Apple II went in because I had designed Breakout for Atari. I had designed it in hardware. I wanted to write it in software now". This included his design of color graphics circuitry, the addition of game paddle support and sound, and graphics commands in Integer BASIC, with which he wrote Brick Out, a software clone of his own hardware game. Wozniak said in 1984: "Basically, all the game features were put in just so I could show off the game I was familiar with—Breakout—at the Homebrew Computer Club. It was the most satisfying day of my life [when] I demonstrated Breakout—totally written in BASIC. It seemed like a huge step to me. After designing hardware arcade games, I knew that being able to program them in BASIC was going to change the world." Overview In the May 1977 issue of Byte, Steve Wozniak published a detailed description of his design; the article began, "To me, a personal computer should be small, reliable, convenient to use, and inexpensive." The Apple II used peculiar engineering shortcuts to save hardware and reduce costs, such as: Taking advantage of the way the 6502 processor accesses memory: it occurs only on alternate phases of the clock cycle; video generation circuitry memory access on the otherwise unused phase avoids memory contention issues and interruptions of the video stream; This arrangement simultaneously eliminated the need for a separate refresh circuit for DRAM chips, as video transfer accessed each row of dynamic memory within the timeout period. In addition, it did not require separate RAM chips for video RAM, while the PET and TRS-80 had SRAM chips for video; Apart from the 6502 CPU and a few support chips, the vast majority of the semiconductors used were 74LS low-power Schottky chips; Rather than use a complex analog-to-digital circuit to read the outputs of the game controller, Wozniak used a simple timer circuit, built around a quad 555 timer IC called a 558, whose period is proportional to the resistance of the game controller, and he used a software loop to measure the timers; A single 14.31818 MHz master oscillator (fM) was divided by various ratios to produce all other required frequencies, including microprocessor clock signals (fM/14), video transfer counters, and color-burst samples (fM/4). A solderable jumper on the main board allowed to switch between European 50 Hz and USA 60 Hz video. The text and graphics screens have a complex arrangement. For instance, the scanlines were not stored in sequential areas of memory. This complexity was reportedly due to Wozniak's realization that the method would allow for the refresh of dynamic RAM as a side effect (as described above). This method had no cost overhead to have software calculate or look up the address of the required scanline and avoided the need for significant extra hardware. Similarly, in high-resolution graphics mode, color is determined by pixel position and thus can be implemented in software, saving Wozniak the chips needed to convert bit patterns to colors. This also allowed to draw text with subpixel rendering, since orange and blue pixels appear half a pixel-width farther to the right on the screen than green and purple pixels. The Apple II at first used data cassette storage, like most other microcomputers of the time. In 1978, the company introduced an external -inch floppy disk drive, called Disk II (stylized as Disk ][), attached through a controller card that plugs into one of the computer's expansion slots (usually slot 6). The Disk II interface, created by Wozniak, is regarded as an engineering masterpiece for its economy of electronic components. The approach taken in the Disk II controller is typical of Wozniak's designs. With a few small-scale logic chips and a cheap PROM (programmable read-only memory), he created a functional floppy disk interface at a fraction of the component cost of standard circuit configurations. Case design The first production Apple II computers had hand-molded cases; these had visible bubbles and other lumps in them from the imperfect plastic molding process, which was soon switched to machine molding. In addition, the initial case design had no vent openings, causing high heat buildup from the PCB and resulting in the plastic softening and sagging. Apple added vent holes to the case within three months of production; customers with the original case could have them replaced at no charge. PCB revisions The Apple II's printed circuit board (PCB) underwent several revisions, as Steve Wozniak made modifications to it. The earliest version was known as Revision 0, and the first 6,000 units shipped used it. Later revisions added a color killer circuit to prevent color fringing when the computer was in text mode, as well as modifications to improve the reliability of cassette I/O. Revision 0 Apple IIs powered up in an undefined mode and had garbage on-screen, requiring the user to press Reset. This was eliminated in later board revisions. Revision 0 Apple IIs could display only four colors in hi-res mode, but Wozniak was able to increase this to six hi-res colors on later board revisions. The PCB had three RAM banks for a total of 24 RAM chips. Original Apple IIs had jumper switches to adjust RAM size, and RAM configurations could be 4, 8, 12, 16, 20, 24, 32, 36, or 48 KiB. The three smallest memory configurations used 4kx1 DRAMs, with larger ones using 16kx1 DRAMs, or mix of 4-kilobyte and 16-kilobyte banks (the chips in any one bank have to be the same size). The early Apple II+ models retained this feature, but after a drop in DRAM prices, Apple redesigned the circuit boards without the jumpers, so that only 16kx1 chips were supported. A few months later, they started shipping all machines with a full 48 KiB complement of DRAM. Unlike most machines, all integrated circuits on the Apple II PCB were socketed; although this cost more to manufacture and created the possibility of loose chips causing a system malfunction, it was considered preferable to make servicing and replacement of bad chips easier. The Apple II PCB lacks any means of generating an interrupt request, although expansion cards may generate one. Program code had to stop everything to perform any I/O task; like many of the computer's other idiosyncrasies, this was due to cost reasons and Steve Wozniak assuming interrupts were not needed for gaming or using the computer as a teaching tool. Display and graphics Color on the Apple II series uses a quirk of the NTSC television signal standard, which made color display relatively easy and inexpensive to implement. The original NTSC television signal specification was black and white. Color was added later by adding a 3.58-megahertz subcarrier signal that was partially ignored by black-and-white TV sets. Color is encoded based on the phase of this signal in relation to a reference color burst signal. The result is that the position, size, and intensity of a series of pulses define color information. These pulses can translate into pixels on the computer screen, with the possibility of exploiting composite artifact colors. The Apple II display provides two pixels per subcarrier cycle. When the color burst reference signal is turned on and the computer attached to a color display, it can display green by showing one alternating pattern of pixels, magenta with an opposite pattern of alternating pixels, and white by placing two pixels next to each other. Blue and orange are available by tweaking the pixel offset by half a pixel-width in relation to the color-burst signal. The high-resolution display offers more colors by compressing more (and narrower) pixels into each subcarrier cycle. The coarse, low-resolution graphics display mode works differently, as it can output a pattern of dots per pixel to offer more color options. These patterns are stored in the character generator ROM, and replace the text character bit patterns when the computer is switched to low-res graphics mode. The text mode and low-res graphics mode use the same memory region and the same circuitry is used for both. A single HGR page occupied 8 KiB of RAM; in practice this meant that the user had to have at least 12 KiB of total RAM to use HGR mode and 20 KiB to use two pages. Early Apple II games from the 1977–79 period often ran only in text or low-resolution mode in order to support users with small memory configurations; HGR not being near universally supported by games until 1980. Sound Rather than a dedicated sound-synthesis chip, the Apple II has a toggle circuit that can only emit a click through a built-in speaker or a line-out jack; all other sounds (including two-, three- and, eventually, four-voice music and playback of audio samples and speech synthesis) are generated entirely by software that clicked the speaker at just the right times. Similar techniques are used for cassette storage: cassette output works the same as the speaker, and input is a simple zero-crossing detector that serves as a relatively crude (1-bit) audio digitizer. Routines in machine ROM encode and decode data in frequency-shift keying for the cassette. Programming languages Initially, the Apple II was shipped with Integer BASIC encoded in the motherboard ROM chips. Written by Wozniak, the interpreter enabled users to write software applications without needing to purchase additional development utilities. Written with game programmers and hobbyists in mind, the language only supported the encoding of numbers in 16-bit integer format. Since it only supported integers between -32768 and +32767 (signed 16-bit integer), it was less suitable to business software, and Apple soon received complaints from customers. Because Steve Wozniak was busy developing the Disk II hardware, he did not have time to modify Integer BASIC for floating point support. Apple instead licensed Microsoft's 6502 BASIC to create Applesoft BASIC. Disk users normally purchased a so-called Language Card, which had Applesoft in ROM, and was sat below the Integer BASIC ROM in system memory. The user could switch between either BASIC by typing FP or INT in BASIC prompt. Apple also offered a different version of Applesoft for cassette users, which occupied low memory, and was started by using the LOAD command in Integer BASIC. As shipped, Apple II incorporated a machine code monitor with commands for displaying and altering the computer's RAM, either one byte at a time, or in blocks of 256 bytes at once. This enabled programmers to write and debug machine code programs without further development software. The computer powers on into the monitor ROM, displaying a * prompt. From there, Ctrl+B enters BASIC, or a machine language program can be loaded from cassette. Disk software can be booted with Ctrl+P followed by 6, referring to Slot 6 which normally contained the Disk II controller. A 6502 assembler was soon offered on disk, and later the UCSD compiler and operating system for the Pascal language were made available. The Pascal system requires a 16 KiB RAM card to be installed in the language card position (expansion slot 0) in addition to the full 48 KiB of motherboard memory. Manual The first 1,000 or so Apple IIs shipped in 1977 with a 68-page mimeographed "Apple II Mini Manual", hand-bound with brass paper fasteners. This was the basis for the Apple II Reference Manual, which became known as the Red Book for its red cover, published in January 1978. All existing customers who sent in their warranty cards were sent free copies of the Red Book. The Apple II Reference Manual contained the complete schematic of the entire computer's circuitry, and a complete source listing of the "Monitor" ROM firmware that served as the machine's BIOS. An Apple II manual signed by Steve Jobs in 1980 with the inscription "Julian, your generation is the first to grow up with computers. Go change the world." sold at auction for $787,484 in 2021. Operating system The original Apple II provided an operating system in ROM along with a BASIC variant called Integer BASIC. The only form of storage available was cassette tape which was inefficiently slow and, worse, unreliable. In 1977 when Apple decided against the popular but clunky CP/M operating system for Wozniak's innovative disk controller design, it contracted Shepardson Microsystems for $13,000 to write an Apple DOS for the Apple II series. At Shepardson, Paul Laughton developed the crucial disk drive software in just 35 days, a remarkably short deadline by any standard. Apple's Disk II -inch floppy disk drive was released in 1978. The final and most popular version of this software was Apple DOS 3.3. Apple DOS was superseded by ProDOS, which supported a hierarchical filesystem and larger storage devices. With an optional third-party Z80-based expansion card, the Apple II could boot into the CP/M operating system and run WordStar, dBase II, and other CP/M software. With the release of MousePaint in 1984 and the Apple IIGS in 1986, the platform took on the look of the Macintosh user interface, including a mouse. Apple released Applesoft BASIC in 1977, a more advanced variant of the language which users could run instead of Integer BASIC for more capabilities. Some commercial Apple II software booted directly and did not use standard DOS disk formats. This discouraged the copying or modifying of the software on the disks, and improved loading speed. Third-party devices and applications When the Apple II initially shipped in June 1977, no expansion cards were available for the slots. This meant that the user did not have any way of connecting a modem or a printer. One popular hack involved connecting a teletype machine to the cassette output. Wozniak's open-architecture design and Apple II's multiple expansion slots permitted a wide variety of third-party devices, including peripheral cards, such as serial controllers, display controllers, memory boards, hard disks, networking components, and real-time clocks. There were plug-in expansion cards—such as the Z-80 SoftCard—that permitted Apple II to use the Z80 processor and run programs for the CP/M operating system, including the dBase II database and the WordStar word processor. The Z80 card also allowed the connection to a modem, and thereby to any networks that a user might have access to. In the early days, such networks were scarce. But they expanded significantly with the development of bulletin board systems in later years. There was also a third-party 6809 card that allowed OS-9 Level One to be run. Third-party sound cards greatly improved audio capabilities, allowing simple music synthesis and text-to-speech functions. Apple II accelerator cards doubled or quadrupled the computer's speed. Early Apple IIs were often sold with a Sup'R'Mod, which allowed the composite video signal to be viewed in a television. The Soviet Union radio-electronics industry designed Apple II-compatible computer Agat. Roughly 12,000 Agat 7 and 9 models were produced and they were widely used in Soviet schools. Agat 9 computers could run "Apple II" compatibility and native modes. "Apple II" mode allowed to run wider variety of (presumably pirated) Apple II software, but at the expense of less RAM. Because of that Soviet developers preferred native mode over "Apple II" compatibility mode. Reception Jesse Adams Stein wrote, "As the first company to release a 'consumer appliance' micro-computer, Apple Computer offers us a clear view of this shift from a machine to an appliance." But the company also had "to negotiate the attitudes of its potential buyers, bearing in mind social anxieties about the uptake of new technologies in multiple contexts. The office, the home and the 'office-in-the-home' were implicated in these changing spheres of gender stereotypes and technological development." After seeing a crude, wire-wrapped prototype demonstrated by Wozniak and Steve Jobs in November 1976, Byte predicted in April 1977, that the Apple II "may be the first product to fully qualify as the 'appliance computer' ... a completed system which is purchased off the retail shelf, taken home, plugged in and used". The computer's color graphics capability especially impressed the magazine. The magazine published a favorable review of the computer in March 1978, concluding: "For the user that wants color graphics, the Apple II is the only practical choice available in the 'appliance' computer class." Personal Computer World in August 1978 also cited the color capability as a strength, stating that "the prime reason that anyone buys an Apple II must surely be for the colour graphics". While mentioning the "oddity" of the artifact colors that produced output "that is not always what one wishes to do", it noted that "no-one has colour graphics like this at this sort of price". The magazine praised the sophisticated monitor software, user expandability, and comprehensive documentation. The author concluded that "the Apple II is a very promising machine" which "would be even more of a temptation were its price slightly lower ... for the moment, colour is an Apple II". Although it sold well from the launch, the initial market was to hobbyists and computer enthusiasts. Sales expanded exponentially into the business and professional market, when the spreadsheet program VisiCalc was launched in mid-1979. VisiCalc is credited as the defining killer app in the microcomputer industry. By the end of 1977 Apple had sales of for the fiscal year, which included sales of the Apple I. This puts Apple clearly behind the others of the "holy trinity" of the TRS-80 and Commodore PET, even though the TRS-80 was launched last of the three. However, during the first five years of operations, revenues doubled about every four months. Between September 1977 and September 1980, annual sales grew from to . During this period the sole products of the company were the Apple II and its peripherals, accessories, and software.

A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities. While tanks are designed for front-line combat, combining operational mobility and tactical offensive and defensive capabilities and performing all primary tasks of the armoured troops, the tank destroyer is specifically designed to take on enemy tanks and other armoured fighting vehicles. Many are based on a tracked tank chassis, while others are wheeled. Since World War II, gun-armed powerful tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armoured anti-tank guided missile (ATGM) carriers are commonly used for supplementary long-range anti-tank work. The resurgence of expeditionary warfare in the first two decades of the 21st century has seen the emergence of gun-armed wheeled vehicles, sometimes called "protected gun systems", which may bear a superficial resemblance to tank destroyers, but are employed as direct fire support units typically providing support in low-intensity operations, as was done in wars in Iraq and Afghanistan. World War II Dedicated anti-tank vehicles made their first major appearance in the Second World War as combatants developed effective armoured vehicles and tactics. Some were little more than stopgap solutions, mounting an anti-tank gun on a tracked vehicle to give mobility, while others were more sophisticated designs. An example of the development of tank destroyer technology throughout the war are the Marder III and Jagdpanzer 38 vehicle, that were very different in spite of being based on the same chassis: Marder was straightforwardly an anti-tank gun on tracks whereas the Jagdpanzer 38 traded some firepower (its 7.5 cm Pak 39, designed to operate within the confines of a fully armoured fighting compartment, fires the same projectiles from a reduced propellant charge compared to Marder's 7.5 cm Pak 40) for better armour protection and ease of concealment on the battlefield. Except for most American designs, all tank destroyers were turretless vehicles with fixed or casemate superstructures. When a tank destroyer was used against enemy tanks from a defensive position such as by ambush, the lack of a rotating turret was not particularly critical, while the lower silhouette was highly desirable. The turretless design allowed accommodation of a more powerful gun, typically a dedicated anti-tank gun (in lieu of a regular tank's general-purpose main gun that fired both anti-tank and high explosive ammunition) that had a longer barrel than could be mounted in a turreted tank on the same chassis. The lack of a turret increased the vehicle's internal volume, allowing for increased ammunition stowage and crew comfort. Eliminating the turret let the vehicle carry thicker armour, and also let this armour be concentrated in the hull. Sometimes there was no armoured roof (only a weather cover) to keep the overall weight down to the limit that the chassis could bear. The absence of a turret meant that tank destroyers could be manufactured significantly cheaper, faster, and more easily than the tanks on which they were based, and they found particular favor when production resources were lacking. Germany The first German tank destroyers were the Panzerjäger ("Tank Hunters"), which mounted an existing anti-tank gun on a convenient chassis for mobility, usually with just a three-sided gun shield for crew protection. For instance, 202 obsolete Panzer I light tanks were modified by removing the turret and were rebuilt as the Panzerjäger I self-propelled 4.7 cm PaK(t). Similarly, Panzer II tanks were used on the eastern front. Captured Soviet anti-tank guns were mounted on modified Panzer II chassis, producing the Marder II self-propelled anti-tank gun. The most common mounting was a German anti-tank gun on the Czech Panzer 38(t) chassis as the Marder III. The Panzer 38(t) chassis was also used to make the Jagdpanzer 38 casemate style tank destroyer. The Panzerjäger series continued up to the equipped Nashorn. German tank destroyers based on the Panzer III medium tank and later German tanks had more armour than their tank counterparts. One of the more successful German tank destroyers was designed as a self-propelled artillery gun, the Sturmgeschütz III. Based on the Panzer III tank chassis, the Sturmgeschütz III was originally fitted with a short barreled low-velocity howitzer-like gun, and was assigned to the artillery arm for infantry fire support as an assault gun. Later, after encountering Soviet tanks, it was refitted with a comparatively short-barreled high-velocity anti-tank gun, usually with a muzzle brake, enabling it to function as a tank destroyer. The Sturmgeschütz III from its 1938 origin used a new casemate-style superstructure with an integrated design, similar to the later Jagdpanzer vehicle designs' superstructure, to completely enclose the crew. It was employed in infantry support and offensive armoured operations as well as in the defensive anti-tank role. The StuG III assault gun was Germany's most-produced fully tracked armoured fighting vehicle during World War II, and second-most produced German armoured combat vehicle of any type after the Sd.Kfz. 251 half-track. Although the early German Panzerjäger carried more effective weapons than the tanks on which they were based, they were generally lacking in protection for the crew, having thinly armoured open-topped superstructures. The "open-topped" design format of the Panzerjäger vehicles was succeeded by the Jagdpanzer ("hunting tanks"), which mounted the gun in true casemate-style superstructures, completely enclosing the crew compartment in armor that was usually integral to the hull. The first of these Jagdpanzers was the 70-ton Ferdinand (later renamed Elefant), based on the chassis, hulls, and drive systems of ninety-one Porsche VK4501 (P) heavy tanks, mounting a long-barreled 88 mm cannon in an added casemate, more like the earlier Panzerjägers had with their added-on armour shielding for the gun crew, but in the Ferdinand completely enclosing the gun and firing crew in the added casemate, as the later purpose-built Jagdpanzers would. However, the Ferdinand was mechanically unreliable and difficult to maneuver, and once all ninety-one unturreted "Porsche Tiger" hulls/drive systems were converted, no more were built. The German Army had more success with the Jagdpanther. Introduced in mid-1944, the Jagdpanther, of which some 415 examples were produced, was considered the best of the casemate-design Jagdpanzer designs. It featured the same powerful PaK 43 88 mm cannon used on the unwieldy Elefant, now fitted to the chassis of the medium Panther tank, providing greatly improved armour-penetrating capability in a medium-weight vehicle. Facing an increasingly defensive war, the German Army turned to larger and more powerfully armed Jagdpanzer designs, and in July 1944 the first Jagdtiger rolled off the production line; it was the heaviest German armoured fighting vehicle to go into active service. The Jagdtiger was based on the Tiger II heavy tank featured a very large 128 mm PaK 44 cannon and heavy armour protection. Only 88 Jagdtiger vehicles were produced, barely matching the total number of the earlier Ferdinand / Elefant vehicles. They were first deployed to combat units in September 1944. The decision of German armoured vehicle designers to use a casemate-style superstructure for all tank destroyers had the advantage of a reduced silhouette, allowing the crew to more frequently fire from defilade ambush positions. Such designs were also easier and faster to manufacture and offered good crew protection from artillery fire and shell splinters. However, the lack of a rotating turret limited the gun's traverse to a few degrees. This meant that the driver normally had to turn the entire tank onto its target, a much slower process than simply rotating a powered turret. If the vehicle became immobilized due to engine failure or track damage, it could not rotate its gun to counter opposing tanks, making it highly vulnerable to counterfire. This vulnerability was later exploited by opposing tank forces. Even the largest and most powerful of German tank destroyers were found abandoned on the field after a battle, having been immobilized by one or more hits by high explosive (HE) or armour-piercing (AP) shells to the track or front drive sprocket. Italy The most famous Italian tank destroyer of the Second World War was a self-propelled gun. The Semovente da 75/18, based on the M13/40 frame, was developed to support front-line infantry, and therefore had fixed armament: a 75 mm gun in casemate. However, thanks to its low height (185 cm) and the caliber of its gun the 75/18 also had good results in anti-tank combat, fighting against British and American (but not Soviet) units. After the Armistice of 1943, the 75/18 remained in use by German forces. Built on the same frame, the Semovente da 105/25 was equipped with a 105 mm gun and known as "bassotto" (Italian for dachshund) due to its lower height. As manufacturing began in 1943, the 105/25 was used by German forces. A further development was the Semovente da 75/46, which had a longer gun than the 75/18 and inclined armour 100 mm thick, making it similar to Sturmgeschütz III. Only 11 of these were manufactured. Before the Semovente da 75/18, the L40, built on an L6/40 light tank chassis, saw action in Africa and in Russia, but with disappointing results. Japan The Type 1 Ho-Ni I was the first self-propelled gun design of the Imperial Japanese Army. They were meant to be self-propelled artillery and tank destroyers for armoured divisions. The plan was for the Type 1 Ho-Ni I gun tank to form part of a fire support company in each of the tank regiments. The Type 1 Ho-Ni I was developed by using the existing Type 97 Chi-Ha medium tank chassis and engine, and replacing the gun turret with a Type 90 75 mm field gun mounted in an open casemate with frontal and side armour only. They entered service in 1942 and were first deployed in combat at the Battle of Luzon in the Philippines in 1945. Some were used in static entrenched positions. A variant, known as the Type 1 Ho-Ni II mounted a Type 91 105 mm howitzer and had a slightly changed superstructure as far as the side armor with re-positioned observation visors. Production began in 1943, with only 54 completed. The other variant produced was the Type 3 Ho-Ni III, which mounted a Type 3 75 mm tank gun in a completely enclosed armored casemate to address the issue of crew protection in close combat. The welded superstructure had sloped armour and the gun mount had additional stamped armour plate. The total number produced of all three types in the Ho-Ni series were 111 units. Most of the Ho-Ni units were retained within the Japanese home islands to form part of the defenses against the projected American invasion, and did not see combat before the surrender of Japan. The Type 2 Ho-I Gun tank used the Type 1 Chi-He medium tank chassis. It was designed as a self-propelled howitzer, mounting a short barreled Type 99 75 mm gun to provide close-in fire support. For deployment, the gun tank was intended to be used in a fire support company for each of the tank regiments. No Type 2 Ho-I gun tanks are known to have engaged in combat prior to Japan's surrender. The prototype was built in 1942 and 31 units were produced in 1944. The Type 4 Ho-Ro self-propelled artillery used a modified Type 97 chassis. On to this platform, a Type 38 150 mm howitzer was mounted. The main gun could fire Type 88 APHE rounds and HEAT rounds. Given its breech loader, the maximum rate of fire was only 5 rounds per minute. The gun's elevation was restricted to 30 degrees by the construction of the chassis. Other design issues included the fact that although the gun crew was protected by a gun shield with armour thickness of 25 mm at the front, the shield only extended a very short distance on the sides; leaving the rest of the sides and back exposed. They were rushed into service, deployed and saw combat during the Philippines Campaign in the last year of World War II. Remaining units were deployed to Okinawa in ones and twos for island defense during the Battle of Okinawa, but were severely outnumbered by American artillery. Soviet Union As with the Germans of 1943, most of the Soviet designs mounted anti-tank guns, with limited traverse in casemate-style turretless hulls, in a general design format looking much like the Germans' own Jagdpanzer vehicles. The results were smaller, lighter, and simpler to build weapons that could carry larger guns than any contemporary tank, including the King Tiger. The Soviets produced high numbers of the SU-85 and SU-100 self-propelled guns based on the same chassis as the T-34 medium tank; the heavier-duty powertrain and hull of the IS-2 heavy tank were instead used to produce the heavier-hitting -armed ISU-122 and -armed ISU-152, both of which had impressive anti-tank capabilities earning each of them the Russian nickname Zveroboy ("beast killer") for their ability to destroy German Tigers, Panthers and Elefants. The predecessor of the ISU 152 was the SU-152, built on the KV-1s chassis and shared many similarities (including its gun) with the ISU-152. The ISU-152 built as a heavy assault gun, relied on the weight of the shell fired from its M-1937/43 howitzer to defeat tanks. In 1943, the Soviets also shifted all production of light tanks like the T-70 to much simpler and better-armed SU-76 self-propelled guns, which used the same drive train. The SU-76 was originally designed as an anti-tank vehicle, but was soon relegated to the infantry-support role. United States U.S. Army and counterpart British designs were very different in conception. U.S. doctrine was based, in light of the fall of France, on the perceived need to defeat German blitzkrieg tactics, and U.S. units expected to face large numbers of German tanks, attacking on relatively narrow fronts. These were expected to break through a thin screen of anti-tank guns, hence the decision that the main anti-tank units—the Tank Destroyer (TD) battalions—should be concentrated and very mobile. In practice, such German attacks rarely happened. Throughout the war, only one battalion ever fought in an engagement like that originally envisaged (the 601st, at the Battle of El Guettar). The Tank Destroyer Command eventually numbered over 100,000 men and 80 battalions each equipped with 36 self-propelled tank destroyers or towed guns. Only a few shots were expected to be fired from any firing position. Strong reconnaissance elements were provided so that TDs could use pre-arranged firing positions to best advantage. Flanking fire by TDs was emphasized, both to penetrate thinner enemy side armour, and to reduce the likelihood of accurate enemy return fire. All American tank destroyers were officially known by exactly the same collective term used for American self-propelled artillery ordnance, "gun motor carriage". The designs were intended to be very mobile and heavily armed. Most of the tank-hull based designs used special open-topped turrets of a differing design from the original tank it was based on, which was meant to both save weight and to accommodate a larger gun. The earliest expedient design was mounting an 75 mm M1897 field gun in a limited-traverse mount on a M3 Half-track which was designated 75 mm Gun Motor Carriage M3. Another, considerably less successful, early design was the M6 Gun Motor Carriage which mounted the US 37-mm anti-tank gun facing to the rear on the bed of a Dodge 3/4-ton light truck. The M3 was first used against the Japanese in the Philippines and then in the Tunisian campaign of the war in North Africa. Some were supplied to British units who used them within armoured car reconnaissance regiments for fire support. The M6 GMC was unarmoured and the 37mm gun was infective against most enemy tanks by the time it entered service. By far the most common US design, and the first that was fully tracked and turreted (which became the American hallmark of World War II "tank destroyer" design) was the 3in Gun Motor Carriage M10, later supplemented by the 90 mm Gun Motor Carriage M36—both based on the M4 Sherman hull and powertrain—and the 76 mm Gun Motor Carriage M18 (Hellcat), based on a unique hull and powertrain design, with a slight visual resemblance to what was used for the later M24 Chaffee light tank. The M18 came closest to the US ideal; the vehicle was very fast, small, and mounted a gun in a roofless open turret. The M36 Jackson GMC possessed the only American-origin operational gun that could rival the German 8.8 cm Pak 43 anti-tank gun and its tank mounted variant, the 90 mm M3 gun, and the M36 remained in service well after World War II. The only dedicated American casemate hull design fighting vehicle of any type built during the war, that resembled the German and Soviet tank destroyers in hull and general gun mounting design, was the experimental T28 Super Heavy Tank, which mounted a 105 mm T5E1 long-barrel cannon. This gun had a maximum firing range of 12 miles (20 km), and the vehicle was originally designed as a very heavily armoured self-propelled assault gun to breach Germany's Siegfried Line defenses. Of these tank destroyers, only the gun of the M36 proved effective against the frontal armour of Germans' larger armored vehicles at long range. The open top and light armour made these tank destroyers vulnerable to anything greater than small-arms fire. As the number of German tanks encountered by American forces steadily decreased throughout the war, most battalions were split up and assigned to infantry units as supporting arms, fighting as assault guns or being used essentially as tanks. In this sense they were an alternative to the Independent tank battalions that were attached to various Infantry Divisions. The expectation that German tanks would be engaged in mass formation was a failed assumption. In reality, German attacks effectively used combined arms on the ground, fighting cohesively. American tank destroyer battalions comprised three tank destroyer companies supported by nine security sections. The single-purpose tactics of the tank destroyer battalion failed to account for non-tank threats. In the 1950s the goal of providing airborne forces with a parachute-capable self-propelled anti-tank weapon led to the deployment of the M56 Scorpion and M50 Ontos. The concept later led to the M551 Sheridan light tank of the mid-1960s. United Kingdom British tanks in the early years of the war, both infantry tanks and cruiser tanks, were (with the exception of the pre-war Matilda I design) equipped with a gun capable of use against contemporary enemy tanks—the 40 mm Ordnance QF 2 pounder. This was replaced with the 57 mm Ordnance QF 6 pounder when that became available. There was extra impetus given to the development of anti-tank weaponry, which culminated in the 76mm Ordnance QF 17 pounder, widely considered one of the best anti-tank guns of the war. Towed anti-tank guns were the domain of the Royal Artillery and vehicles adapted to mount artillery, including anti-tank self-propelled guns such as the Deacon (6pdr on an armoured wheeled truck chassis) and Archer (17pdr on tracked chassis) and US-supplied vehicles, were their preserve rather than the Royal Armoured Corps. The self-propelled guns that were built in the "tank destroyer" mould came about through the desire to field the QF 17 pounder anti-tank gun and simultaneous lack of suitable standard tanks to carry it. As a result, they were of a somewhat extemporized nature. Mounting the gun on the Valentine tank chassis in a fixed superstructure gave the Archer, looking somewhat like the light-chassis German Marder III in appearance. The 17 pounder was also used to re-equip the US-supplied M10 Tank Destroyer, replacing the American 3-inch gun to produce the 17pdr SP Achilles. In 1942 the General Staff agreed on investigating self-propelled mountings of the 6-pounder, 17-pounder, 3-inch 20cwt guns and the 25-pounder field gun/howitzer on the Matilda II, Valentine, Crusader and Cavalier (Cruiser Mark VII) tank chassis. In October 1942 it was decided to progress using the Valentine chassis with a 17-pdr (which would become Archer) and 25-pdr (which entered service as Bishop). While there was a general move to a general purpose gun that was usable against both tanks and in supporting infantry, there was a need to put the 17 pdr into a tank for use against the enemy's heavy tanks. The Cruiser Mk VIII Challenger was a project to bring a 17 pdr tank into use to support the Cromwell cruiser tank. Delays led to it being outnumbered in use by the Sherman Firefly—but a derivative of Challenger was the more or less open-topped variant Avenger, which was delayed until post war before entering service. A cut-down 17 pdr, the 77mmHV was used to equip the Comet tank in the last year of the war. The closest the British came to developing an armoured tank destroyer in the vein of the German Jagdpanzers or Soviet ISU series was the Churchill 3-inch Gun Carrier—a Churchill tank chassis with a boxy superstructure in place of the turret and mounting a 3-inch anti-aircraft gun. Although a number were ordered and fifty delivered in 1942, they were not put into service as the immediate threat passed. The design was rejected in favor of developing a 17 pounder armed Cromwell tank variant, ultimately leading to the Comet tank. The Tortoise "heavy assault tank", intended for use in breaking through fixed defensive lines, was well armoured and had a very powerful 32-pounder (94 mm) gun, but did not reach service use. By 1944, a number of the Shermans in British use were being converted to Sherman Fireflies by adding the QF 17 pounder gun. Initially this gave each troop (platoon) of Shermans one powerfully armed tank. By war's end—through the production of more Fireflies and the replacement of Shermans by British tanks—about 50% of Shermans in British service were Fireflies. The Sherman Firefly, however, is not considered a tank destroyer since it could still perform the other duties of the regular M4 Sherman, albeit the Firefly was less capable due to the late development of a HE round for the QF 17 pounder. Romania Until 1942, the Romanian tank force was equipped exclusively with obsolete R-1, R-2 and R35 tanks. Having faced big problems against Soviet T-34 and KV-1 tanks on the Eastern Front, the Romanian Army leadership sought for ways to improve its anti-tank capabilities. The initial plan was the creation of a tank comparable in characteristics to the T-34; instead, Romania went for a number of tank destroyers, since they were more adequate for its industry. The Mareșal is probably the best known Romanian AFV from the war; historians Steven Zaloga and Mark Axworthy state that it inspired the design of the later German Hetzer. Standing at only around 1.5 m tall, which would have made it very difficult to hit for its enemies, the Mareșal was a lightly armored, but highly mobile vehicle. It was armed with the Romanian 75 mm Reșița M1943 anti-tank gun, which proved to be among the best of its class during World War II, according to Mark Axworthy. During tests, the Mareșal proved to be superior in many aspects to the StuG III G, against which it competed. Those facts suggest that the Mareșal would have been an effective tank destroyer, had it been deployed into combat. There were, however, also critics of the vehicle, especially among high-ranking Romanian officials. It never saw action because the invading Soviet army had stopped its production. Other Romanian tank destroyers include the TACAM R-2 and TACAM T-60, which were converted from R-2 and T-60 light tanks respectively. Both of them saw action. One TACAM R-2 survives today and is displayed at the National Military Museum in Bucharest. Another conversion was the VDC R-35, Romania's only turreted tank destroyer. Two other proposed tank destroyers existed: the TACAM R-1 and TACAM T-38. Poland Variants of the Polish TKS and TK-3 tankettes up-armed with 20 mm gun (23–26 vehicles) were operationally deployed in the invasion of Poland. They were used as an anti-tank component of the reconnaissance units. There were also 37 mm armed TKS-D (2 experimental vehicles) and 47 mm armed TKD (4 experimental vehicles). It is not certain whether they were used operationally at all. France Due to the quick defeat of France, few French vehicles were built. The Laffly W15 TCC (Chasseur de chars) was an attempt to quickly build a light tank destroyer by mounting a 47 mm SA37 anti-tank gun onto a lightly armoured Laffly W15T artillery tractor. Other French tank destroyers were being developed, including the SOMUA SAu-40, ARL V39 and various ad hoc conversions of the Lorraine 37L. Subsequent developments Missile-based tank destroyers In the face of the Warsaw Pact, a general need for extra firepower was identified. In the late 1960s, West Germany developed the Kanonenjagdpanzer, essentially a modernized World War II Jagdpanzer mounting a gun. As Soviet designs became more heavily armoured, the gun became ineffective and the Kanonenjagdpanzers were retrofitted for different roles or retired. Some provisions were made for the fitting of a 105 mm cannon, and many of the vehicles were modified to fire HOT or TOW missiles in place of a main gun. These upgraded variants remained in service into the 1990s. With the development of flexible anti-tank missiles, which were capable of installation on almost any vehicle in the 1960s, the concept of the tank destroyer has morphed into light vehicles with missiles. With the weight of main battle tanks growing to the forty to seventy-tonne range, airborne forces were unable to deploy reasonable anti-tank forces. The result was a number of attempts to make a light vehicle, including the conventional ASU-85, M56 Scorpion, the recoilless rifle-armed Ontos, and missile-armed Humber Hornet armoured truck and Sheridan light assault vehicle. The recent entries into that category are the 2S25 Sprut-SD, armed with a current-issue 125 mm tank gun that is also capable of launching missiles like the 9M119 Svir, and Israeli-modified Pandur IIs, which is to enter service with the Philippine Army by 2022 armed with an Elbit Turret and a 105 mm gun. Many forces' infantry fighting vehicles (IFVs) carry anti-tank missiles in every infantry platoon, and attack helicopters have also added anti-tank capability to the modern battlefield. But there are still dedicated anti-tank vehicles with very heavy long-range missiles, and ones intended for airborne use. There have also been dedicated anti-tank vehicles built on ordinary armoured personnel carrier or armored car chassis. Examples include the U.S. M901 ITV (Improved TOW Vehicle) and the Norwegian NM142, both on an M113 chassis, several Soviet ATGM launchers based on the BRDM reconnaissance car, the British FV438 Swingfire and FV102 Striker and the German Raketenjagdpanzer series built on the chassis of the HS 30 and Marder IFV. India fielded NAMIS (Nag Missile System) equipped with Nag Missiles. A US Army combined arms battalion has two infantry companies with TOW missile-armed Bradley IFVs and can bring a large concentration of accurate and lethal fire to bear on an attacking enemy unit that uses AFVs. They can be complemented by mobile units of AH-64 Apache helicopters armed with Hellfire antitank missiles. Missile carrying vehicles are often referred to as anti-tank missile carriers instead of tank destroyers. Postwar gun-based tank destroyers Despite the proliferation of ATGMs, some gun-armed tank destroyers remain in use. China has developed the tracked PTZ89 and the wheeled PTL02 tank destroyers. The PTZ89 is armed with a smoothbore cannon while the PTL02, developed by NORINCO for the PLA's new light (rapid reaction) mechanized infantry divisions, carries a one (a version armed with a 105 mm rifled gun is available for export). The PTL02 is built on the 6×6 wheeled chassis of the WZ551 APC. Italy and Spain use the Italian-built Centauro, a wheeled tank destroyer with a cannon. Russia, meanwhile, uses the Russian-built 2S25 Sprut-SD, operating as an amphibious light tank/tank destroyer armed with a cannon. The Sabrah Pandur II is a Wheeled tank destroyer variant of the Sabrah Light Tank developed by the Elbit Systems of Israel for the Philippine Army's future combat systems. The U.S. Army utilized the wheeled M1128 Mobile Gun System until 2022.

A military armored (also spelled armoured) car is a lightweight wheeled armored fighting vehicle, historically employed for reconnaissance, internal security, armed escort, and other subordinate battlefield tasks. With the gradual decline of mounted cavalry, armored cars were developed for carrying out duties formerly assigned to light cavalry. Following the invention of the tank, the armored car remained popular due to its faster speed, comparatively simple maintenance and low production cost. It also found favor with several colonial armies as a cheaper weapon for use in underdeveloped regions. During World War II, most armored cars were engineered for reconnaissance and passive observation, while others were devoted to communications tasks. Some equipped with heavier armament could even substitute for tracked combat vehicles in favorable conditions—such as pursuit or flanking maneuvers during the North African Campaign. Since World War II the traditional functions of the armored car have been occasionally combined with that of the armored personnel carrier, resulting in such multipurpose designs as the BTR-40 or the Cadillac Gage Commando. Postwar advances in recoil control technology have also made it possible for a few armored cars, including the B1 Centauro, the Panhard AML, the AMX-10 RC and EE-9 Cascavel, to carry a large cannon capable of threatening many tanks. History Precursors During the Middle Ages, war wagons covered with steel plate, and crewed by men armed with primitive hand cannon, flails and muskets, were used by the Hussite rebels in Bohemia. These were deployed in formations where the horses and oxen were at the centre, and the surrounding wagons were chained together as protection from enemy cavalry. With the invention of the steam engine, Victorian inventors designed prototype self-propelled armored vehicles for use in sieges, although none were deployed in combat. H. G. Wells' short story "The Land Ironclads" provides a fictionalized account of their use. Armed car The Motor Scout was designed and built by British inventor F.R. Simms in 1898. It was the first armed petrol engine-powered vehicle ever built. The vehicle was a De Dion-Bouton quadricycle with a mounted Maxim machine gun on the front bar. An iron shield in front of the car protected the driver. Another early armed car was invented by Royal Page Davidson at Northwestern Military and Naval Academy in 1898 with the Davidson-Duryea gun carriage and the later Davidson Automobile Battery armored car. However, these were not "armored cars" as the term is understood today, as they provided little protection for their crews from enemy fire. First armored cars At the beginning of the 20th century, the first military armored vehicles were manufactured, by adding armor and weapons to existing vehicles. The first armored car was the Simms' Motor War Car, designed by F.R. Simms and built by Vickers, Sons & Maxim of Barrow on a special Coventry-built Daimler chassis with a German-built Daimler motor in 1899. and a single prototype was ordered in April 1899 The prototype was finished in 1902, too late to be used during the Boer War. The vehicle had Vickers armor, thick, and was powered by a four-cylinder Cannstatt Daimler engine, giving it a maximum speed of around . The armament, consisting of two Maxim guns, was carried in two turrets with 360° traverse. It had a crew of four. Simms' Motor War Car was presented at the Crystal Palace, London, in April 1902. Another early armored car of the period was the French Charron, Girardot et Voigt 1902, presented at the Salon de l'Automobile et du cycle in Brussels, on 8 March 1902. The vehicle was equipped with a Hotchkiss machine gun, and with armour for the gunner. One of the first operational armored cars with four wheel (4x4) drive and partly enclosed rotating turret, was the Austro-Daimler Panzerwagen built by Austro-Daimler in 1904. It was armored with thick curved plates over the body (drive space and engine) and had a thick dome-shaped rotating turret that housed one or two machine-guns. It had a four-cylinder engine giving it average cross country performance. Both the driver and co-driver had adjustable seats enabling them to raise them to see out of the roof of the drive compartment as needed. The Spanish Schneider-Brillié was the first armored vehicle to be used in combat, being first used in the Kert Campaign. The vehicle was equipped with two machineguns and built from a bus chassis. An armored car known as the ''Death Special'' was built at the CFI plant in Pueblo and used by the Badlwin-Felts detective agency during the Colorado Coalfield War A great variety of armored cars appeared on both sides during World War I and these were used in various ways. World War I Generally, armored cars were used by more or less independent car commanders. However, sometimes they were used in larger units up to squadron size. The cars were primarily armed with light machine guns, but larger units usually employed a few cars with heavier guns. As air power became a factor, armored cars offered a mobile platform for antiaircraft guns. The first effective use of an armored vehicle in combat was achieved by the Belgian Army in August–September 1914. They had placed Cockerill armour plating and a Hotchkiss machine gun on Minerva touring cars, creating the Minerva Armored Car. Their successes in the early days of the war convinced the Belgian GHQ to create a Corps of Armoured Cars, who would be sent to fight on the Eastern front once the western front immobilized after the Battle of the Yser. The British Royal Naval Air Service dispatched aircraft to Dunkirk to defend the UK from Zeppelins. The officers' cars followed them and these began to be used to rescue downed reconnaissance pilots in the battle areas. They mounted machine guns on them and as these excursions became increasingly dangerous, they improvised boiler plate armoring on the vehicles provided by a local shipbuilder. In London Murray Sueter ordered "fighting cars" based on Rolls-Royce, Talbot and Wolseley chassis. By the time Rolls-Royce Armoured Cars arrived in December 1914, the mobile period on the Western Front was already over. They had a fascinating birth and long and interesting service. More tactically important was the development of formed units of armored cars, such as the Canadian Automobile Machine Gun Brigade, which was the first fully mechanized unit in the history of the British Army. The brigade was established on September 2, 1914, in Ottawa, as Automobile Machine Gun Brigade No. 1 by Brigadier-General Raymond Brutinel. The brigade was originally equipped with eight Armoured Autocars mounting two machine guns. By 1918 Brutinel's force consisted of two motor machine gun brigades (each of five gun batteries containing eight weapons apiece). The brigade, and its armored cars, provided yeoman service in many battles, notably at Amiens. The Rolls-Royce Armoured Car was famously proposed, developed, and utilized by the 2nd Duke of Westminster. He took a squadron of these cars to France in time to make a noted contribution to the Second Battle of Ypres, and thereafter the cars with their master were sent to the Middle East to play a part in the British campaign in Palestine and elsewhere. These cars appear in the memoirs of numerous officers of the BEF during the earlier stages of the Great War - their ducal master often being described in an almost piratical style. Armored cars also saw action on the Eastern Front. From 18 February - 26 March 1915, the German army under General Max von Gallwitz attempted to break through the Russian lines in and around the town of Przasnysz, Poland, (about 110 km / 68 miles north of Warsaw) during the Battle of Przasnysz (Polish: Bitwa przasnyska). Near the end of the battle, the Russians used four Russo-Balt armored cars and a armored car to break through the Germans' lines and force the Germans to retreat. World War II The British Royal Air Force (RAF) in the Middle East was equipped with Rolls-Royce Armoured Cars and Morris tenders. Some of these vehicles were among the last of a consignment of ex-Royal Navy armored cars that had been serving in the Middle East since 1915. In September 1940 a section of the No. 2 Squadron RAF Regiment Company was detached to General Wavell's ground forces during the first offensive against the Italians in Egypt. It is said that these armored cars became 'the eyes and ears of Wavell'. During the actions in the October of that year the company was employed on convoy escort tasks, airfield defense, fighting reconnaissance patrols and screening operations. During the 1941 Anglo-Iraqi War, some of the units located in the British Mandate of Palestine were sent to Iraq and drove Fordson armored cars. "Fordson" armored cars were Rolls-Royce armored cars which received new chassis from a Fordson truck in Egypt. By the start of the new war, the German army possessed some highly effective reconnaissance vehicles, such as the Schwerer Panzerspähwagen. The Soviet BA-64 was influenced by a captured Leichter Panzerspähwagen before it was first tested in January 1942. In the second half of the war, the American M8 Greyhound and the British Daimler Armoured Cars featured turrets mounting light guns (40 mm or less). As with other wartime armored cars, their reconnaissance roles emphasized greater speed and stealth than a tracked vehicle could provide, so their limited armor, armament and off-road capabilities were seen as acceptable compromises. Military use A military armored car is a type of armored fighting vehicle having wheels (from four to ten large, off-road wheels) instead of tracks, and usually light armor. Armored cars are typically less expensive and on roads have better speed and range than tracked military vehicles. They do however have less mobility as they have less off-road capabilities because of the higher ground pressure. They also have less obstacle climbing capabilities than tracked vehicles. Wheels are more vulnerable to enemy fire than tracks, they have a higher signature and in most cases less armor than comparable tracked vehicles. As a result, they are not intended for heavy fighting; their normal use is for reconnaissance, command, control, and communications, or for use against lightly armed insurgents or rioters. Only some are intended to enter close combat, often accompanying convoys to protect soft-skinned vehicles. Light armored cars, such as the British Ferret are armed with just a machine gun. Heavier vehicles are armed with autocannon or a large caliber gun. The heaviest armored cars, such as the German, World War II era Sd.Kfz. 234 or the modern, US M1128 Mobile Gun System, mount the same guns that arm medium tanks. Armored cars are popular for peacekeeping or internal security duties. Their appearance is less confrontational and threatening than tanks, and their size and maneuverability is said to be more compatible with tight urban spaces designed for wheeled vehicles. However, they do have a larger turning radius compared to tracked vehicles which can turn on the spot and their tires are vulnerable and are less capable in climbing and crushing obstacles. Further, when there is true combat they are easily outgunned and lightly armored. The threatening appearance of a tank is often enough to keep an opponent from attacking, whereas a less threatening vehicle such as an armored car is more likely to be attacked. Many modern forces now have their dedicated armored car designs, to exploit the advantages noted above. Examples would be the M1117 Armored Security Vehicle of the USA or Alvis Saladin of the post-World War II era in the United Kingdom. Alternatively, civilian vehicles may be modified into improvised armored cars in ad hoc fashion. Many militias and irregular forces adapt civilian vehicles into AFVs (armored fighting vehicles) and troop carriers, and in some regional conflicts these "technicals" are the only combat vehicles present. On occasion, even the soldiers of national militaries are forced to adapt their civilian-type vehicles for combat use, often using improvised armor and scrounged weapons. Scout cars In the 1930s, a new sub-class of armored car emerged in the United States, known as the scout car. This was a compact light armored car which was either unarmed or armed only with machine guns for self-defense. Scout cars were designed as purpose-built reconnaissance vehicles for passive observation and intelligence gathering. Armored cars which carried large caliber, turreted weapons systems were not considered scout cars. The concept gained popularity worldwide during World War II and was especially favored in nations where reconnaissance theory emphasized passive observation over combat. Examples of armored cars also classified as scout cars include the Soviet BRDM series, the British Ferret, the Brazilian EE-3 Jararaca, the Hungarian D-442 FÚG, and the American Cadillac Gage Commando Scout.

An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft capability. Specific weapon systems used include machine guns, autocannons, larger guns, or missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir-S1). Platforms used include both trucks and heavier combat vehicles such as armored personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment. Anti-aircraft guns are usually mounted in a quickly-traversing turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, missiles (generally mounted on similar turrets) have largely supplanted anti-aircraft guns, but they may return as a cheap way to counter unmanned aerial systems (drones). History World War I Anti-aircraft machine guns have long been mounted on trucks, and these were quite common during World War I. A predecessor of the WWII German "88" anti-aircraft gun, the WWI German 77 mm anti-aircraft gun, was truck-mounted and used to great effect against British tanks. The British QF 3 inch 20 cwt was mounted on trucks for use on the Western Front. The British also had a first dedicated anti aircraft weapon, the QF 1-pounder pom-pom. Mounted on a armoured truck titled the Pierce-Arrow armoured AA lorry, which was produced in limited numbers and only seeing service throughout 1915. Towards the end of the war Germany produced three prototype SPAAGs with AA guns mounted on A7V chassis known as the A7V Flakpanzer. Inter-war period Between the two World Wars, the United Kingdom developed the Birch gun, a general-purpose artillery piece on an armoured tracked chassis capable of maintaining formation with their current tanks over terrain. The gun could be elevated for anti-aircraft use. The first tracked SPAAG-design to be manufactured in series was most likely the British/Siamese Vickers Armstrong "Type 76" (per Buddhist year 2476 = 1933 CE), as named by the Royal Siamese Army, a SPAAG based on the chassis of the Dragon, Medium, Mark IV artillery tractor (Vickers Mk.E 6-ton light tank derivative), mounting a revolving Vickers 40 mm QF 2 pounder pom-pom autocannon in an open fighting compartment. About 26 were sold to Siam in 1932 and saw action as infantry support guns and AA guns during the Franco-Thai war (1940-1941) along with 30 Vickers Mk.E Type B 6-ton tanks. Despite being the first tracked SPAAG en masse, the open-top design of the Vickers Type 76 made it outdated even by the early 1930s. The first modern SPAAG to be produced was most likely the Swedish Landsverk L-62 Anti in 1936, featuring a tracked armoured body with a revolving turret, a so-called anti-aircraft tank. It was based on a widened chassis of the Landsverk L-60 light tank and was armed with a Bofors 40 mm Automatic Gun L/60 in an open-top revolving turret. The design was bought by Hungary just prior to the war and Finland ordered a refined model in 1941, known as the Anti II. By the late 1930s, the British had developed a version of the Mk.VI Light Tank armed with four machine guns that were known as Light Tank AA Mk.I, and also a twin 15 mm version based on the Light Tank Mk.V was built. Among early pre-war pioneers of self-propelled AA guns were the Germans. By the time of the war, they fielded the Sd.Kfz. 10/4 and Sd.Kfz. 6/2, cargo half-tracks mounting single 20 mm or 37 mm AA guns (respectively). Later in the war similar German half-tracks mounted quadruple 20 mm weapons. World War II Larger guns followed on larger trucks, but these mountings generally required off-truck setup in order to unlimber the stabilizing legs these guns needed. One exception to this rule was the Italian Cannone da 90/53 which was highly effective when mounted on trucks, a fit known as the "autocannoni da 90/53". The 90/53 was a feared weapon, notably in the anti-tank role, but only a few hundred had been produced by the time of the armistice in 1943. Other nations tended to work on truck chassis. Starting in 1941, the British developed the "en portee" method of mounting an anti-tank gun (initially a 2 pounder) on a truck. This was to prevent the weapon from being damaged by long-distance towing across rough, stony deserts, and it was intended only to be a carrying method, with the gun unloaded for firing. However, crews tended to fire their weapons from their vehicles for the mobility this method provided, with consequent casualties. This undoubtedly inspired their Morris C9/B (officially the "Carrier, SP, 4x4, 40 mm AA"), a Bofors 40 mm AA gun mounted on a chassis derived from the Morris "Quad" Field Artillery Tractor truck. Similar types, based on 3-ton lorries, were produced in Britain, Canada and Australia, and together formed the most numerous self-propelled AA guns in British service. The U.S. Army brought truck-towed Bofors 40 mm AA guns along with truck-mounted units fitted with mechanized turrets when they sailed, first for Great Britain and then onto France. The turrets carried four .50 inch (12.7 mm) machine guns, which were designed to be adjusted to converge at the single point where enemy aircraft were expected to appear at low altitude in conduction of strafing runs directed at large infantry and field artillery units. Interest in mobile AA turned to heavier vehicles with the mass and stability needed to easily train weapons of all sizes. Probably the desire, particularly in German service, for anti-aircraft vehicles to be armoured for their own protection also assisted this trend. The concept of using armored SPAAG (anti-aircraft tanks) en masse was pioneered by Hungary during World War II with the production of the 40M Nimrod, a license-produced version of the previously mentioned late 1930s Landsverk L-62 Anti I SPAAG. Germany followed later with their "Flakpanzer" series. German World War II SPAAGs include the Möbelwagen, Wirbelwind, Ostwind and Kugelblitz. Other forces followed with designs of their own, notably the American M16 created by mounting quadruple M2HB Browning machine guns on a M3 Half-track. The British developed their own SPAAGs throughout the war mounting multiple machine guns and light cannon on various tank and armoured car chassis and by 1943, the Crusader AA tanks, which mounted the Bofors 40 mm gun or two-three Oerlikon 20 mm cannon. Although used during the Normandy landings, by that point German aircraft were contained by the Allies own air forces and they were largely unneeded. Cold War and later The introduction of jet engines and the subsequent rough doubling of aircraft speeds greatly reduced the effectiveness of the SPAAG against attack aircraft. A typical SPAAG round might have a muzzle velocity on the order of and might take as long as two to three seconds to reach a target at its maximum range. An aircraft flying at is moving at a rate of about . This means the aircraft will have moved hundreds of meters during the flight time of the shells, greatly complicating the aiming problem to the point where close passes were essentially impossible to aim using manual gunsights. This speed also allowed the aircraft to rapidly fly out of range of the guns; even if the aircraft passes directly over the SPAAG, it would be within its firing radius for under 30 seconds. SPAAG development continued through the early 1950s with ever-larger guns, improving the range and allowing the engagement to take place at longer distances where the crossing angle was smaller and aiming was easier. Examples including the 40 mm U.S. M42 Duster and the 57 mm Soviet ZSU-57-2. However, both were essentially obsolete before they entered service, and found employment solely in the ground-support role. The M42 was introduced to the Vietnam War to counter an expected North Vietnamese air offensive, but when this failed to materialize it was used as an effective direct-fire weapon. The ZSU-57 found similar use in the Yugoslav Wars, where its high-angle fire was useful in the mountainous terrain. By the late 1950s, the US Army had given up on the SPAAG concept, considering all gun-based weapons to be useless against modern aircraft. This belief was generally held by many forces, and the anti-aircraft role turned almost exclusively to missile systems. The Soviet Union remained an outlier, beginning the development of a new SPAAG in 1957, which emerged as the ZSU-23-4 in 1965. This system included search-and-track radars, fire control, and automatic gun-laying, greatly increasing its effectiveness against modern targets. The ZSU-23 proved very effective when used in concert with SAMs; the presence of SAMs forced aircraft to fly low to avoid their radars, placing them within range of the ZSUs. The success of the ZSU-23 led to a resurgence of SPAAG development. This was also prompted by the introduction of attack helicopters in the 1970s, which could hide behind terrain and then "pop up" for an attack lasting only a few tens of seconds; missiles were ineffective at low altitudes, while the helicopters would often be within range of the guns for a rapid counterattack. Notable among these later systems is the German Gepard, the first western SPAAG to offer performance equal to or better than the ZSU. This system was widely copied in various NATO forces. SPAAG development continues, with many modern examples often combining both guns and short-range missiles. Examples include the Soviet/Russian Tunguska-M1, which supplanted the ZSU-23 in service, the newer versions of the Gepard, the Chinese Type 95 SPAAA, and the British Marksman turret, which can be used on a wide variety of platforms. Some forces, like the US Army and USMC have mostly forgone self-propelled guns in favor of systems with short-range infrared-guided surface-to-air missiles in the AN/TWQ-1 Avenger and M6 Linebacker, which do not require radar to be accurate and are generally more reliable and cost-effective to field, though their ability to provide ground support is more limited. The U.S. Army did use the M163 VADS and developed the prototype design of the M247 Sergeant York. Present day Modern SPAAGs usually have short-range missiles for longer range engagement. The Pantsir system from Russia is primarily a missile battery, although it does have twin cannons as secondary armament. Some examples of modern SPAAGs: Stryker M-SHORAD, US/Canada, 30 mm Skyranger 30, 30 mm Skyranger 35, Swiss/German, 35 mm Flakpanzer Gepard, Germany, 35 mm PGZ-09, China, 35 mm KORKUT, Turkey, 35 mm Luftvärnskanonvagn (lvkv) 9040, Sweden, 40 mm PASARS-16, Serbia, 40 mm K30 Biho, South Korea, 30 mm See also 4M (artillery) Assault gun Flakpanzer, a collective term for German anti-aircraft tanks, particularly those used in World War II.

The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three main zones: the zona glomerulosa, the zona fasciculata and the zona reticularis. The adrenal cortex produces three main types of steroid hormones: mineralocorticoids, glucocorticoids, and androgens. Mineralocorticoids (such as aldosterone) produced in the zona glomerulosa help in the regulation of blood pressure and electrolyte balance. The glucocorticoids cortisol and cortisone are synthesized in the zona fasciculata; their functions include the regulation of metabolism and immune system suppression. The innermost layer of the cortex, the zona reticularis, produces androgens that are converted to fully functional sex hormones in the gonads and other target organs. The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells. The medulla produces the catecholamines, which function to produce a rapid response throughout the body in stress situations. A number of endocrine diseases involve dysfunctions of the adrenal gland. Overproduction of cortisol leads to Cushing's syndrome, whereas insufficient production is associated with Addison's disease. Congenital adrenal hyperplasia is a genetic disease produced by dysregulation of endocrine control mechanisms. A variety of tumors can arise from adrenal tissue and are commonly found in medical imaging when searching for other diseases. Structure The adrenal glands are located on both sides of the body in the retroperitoneum, above and slightly medial to the kidneys. In humans, the right adrenal gland is pyramidal in shape, whereas the left is semilunar or crescent shaped and somewhat larger. The adrenal glands measure approximately 5 cm in length, 3 cm in width, and up to 1 cm in thickness. Their combined weight in an adult human ranges from 7 to 10 grams. The glands are yellowish in colour. The adrenal glands are surrounded by a fatty capsule and lie within the renal fascia, which also surrounds the kidneys. A weak septum (wall) of connective tissue separates the glands from the kidneys. The adrenal glands are directly below the diaphragm, and are attached to the crura of the diaphragm by the renal fascia. Each adrenal gland has two distinct parts, each with a unique function, the outer adrenal cortex and the inner medulla, both of which produce hormones. Adrenal cortex The adrenal cortex is the outer region and also the largest part of an adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. The adrenal cortex is the outermost layer of the adrenal gland. Within the cortex are three layers, called "zones". When viewed under a microscope each layer has a distinct appearance, and each has a different function. The adrenal cortex is devoted to production of hormones, namely aldosterone, cortisol, and androgens. Zona glomerulosa The outermost zone of the adrenal cortex is the zona glomerulosa. It lies immediately under the fibrous capsule of the gland. Cells in this layer form oval groups, separated by thin strands of connective tissue from the fibrous capsule of the gland and carry wide capillaries. This layer is the main site for production of aldosterone, a mineralocorticoid, by the action of the enzyme aldosterone synthase. Aldosterone plays an important role in the long-term regulation of blood pressure. Zona fasciculata The zona fasciculata is situated between the zona glomerulosa and zona reticularis. Cells in this layer are responsible for producing glucocorticoids such as cortisol. It is the largest of the three layers, accounting for nearly 80% of the volume of the cortex. In the zona fasciculata, cells are arranged in columns radially oriented towards the medulla. Cells contain numerous lipid droplets, abundant mitochondria and a complex smooth endoplasmic reticulum. Zona reticularis The innermost cortical layer, the zona reticularis, lies directly adjacent to the medulla. It produces androgens, mainly dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione (the precursor to testosterone) in humans. Its small cells form irregular cords and clusters, separated by capillaries and connective tissue. The cells contain relatively small quantities of cytoplasm and lipid droplets, and sometimes display brown lipofuscin pigment. Medulla The adrenal medulla is at the centre of each adrenal gland, and is surrounded by the adrenal cortex. The chromaffin cells of the medulla are the body's main source of the catecholamines, such as adrenaline and noradrenaline, released by the medulla. Approximately 20% noradrenaline (norepinephrine) and 80% adrenaline (epinephrine) are secreted here. The adrenal medulla is driven by the sympathetic nervous system via preganglionic fibers originating in the thoracic spinal cord, from vertebrae T5–T11. Because it is innervated by preganglionic nerve fibers, the adrenal medulla can be considered as a specialized sympathetic ganglion. Unlike other sympathetic ganglia, however, the adrenal medulla lacks distinct synapses and releases its secretions directly into the blood. Blood supply The adrenal glands have one of the greatest blood supply rates per gram of tissue of any organ: up to 60 small arteries may enter each gland. Three arteries usually supply each adrenal gland: The superior suprarenal artery, a branch of the inferior phrenic artery The middle suprarenal artery, a direct branch of the abdominal aorta The inferior suprarenal artery, a branch of the renal artery These blood vessels supply a network of small arteries within the capsule of the adrenal glands. Thin strands of the capsule enter the glands, carrying blood to them. Venous blood is drained from the glands by the suprarenal veins, usually one for each gland: The right suprarenal vein drains into the inferior vena cava. The left suprarenal vein drains into the left renal vein or the left inferior phrenic vein. The central adrenomedullary vein, in the adrenal medulla, is an unusual type of blood vessel. Its structure is different from the other veins in that the smooth muscle in its tunica media (the middle layer of the vessel) is arranged in conspicuous, longitudinally oriented bundles. Variability The adrenal glands may not develop at all, or may be fused in the midline behind the aorta. These are associated with other congenital abnormalities, such as failure of the kidneys to develop, or fused kidneys. The gland may develop with a partial or complete absence of the cortex, or may develop in an unusual location. Function The adrenal gland secretes a number of different hormones which are metabolised by enzymes either within the gland or in other parts of the body. These hormones are involved in a number of essential biological functions. Corticosteroids Corticosteroids are a group of steroid hormones produced from the cortex of the adrenal gland, from which they are named. Mineralocorticoids such as aldosterone regulate salt ("mineral") balance and blood pressure Glucocorticoids such as cortisol influence metabolism rates of proteins, fats and sugars ("glucose"). Androgens such as dehydroepiandrosterone. Mineralocorticoids The adrenal gland produces aldosterone, a mineralocorticoid, which is important in the regulation of salt ("mineral") balance and blood volume. In the kidneys, aldosterone acts on the distal convoluted tubules and the collecting ducts by increasing the reabsorption of sodium and the excretion of both potassium and hydrogen ions. Aldosterone is responsible for the reabsorption of about 2% of filtered glomerular filtrate. Sodium retention is also a response of the distal colon and sweat glands to aldosterone receptor stimulation. Angiotensin II and extracellular potassium are the two main regulators of aldosterone production. The amount of sodium present in the body affects the extracellular volume, which in turn influences blood pressure. Therefore, the effects of aldosterone in sodium retention are important for the regulation of blood pressure. Glucocorticoids Cortisol is the main glucocorticoid in humans. In species that do not create cortisol, this role is played by corticosterone instead. Glucocorticoids have many effects on metabolism. As their name suggests, they increase the circulating level of glucose. This is the result of an increase in the mobilization of amino acids from protein and the stimulation of synthesis of glucose from these amino acids in the liver. In addition, they increase the levels of free fatty acids, which cells can use as an alternative to glucose to obtain energy. Glucocorticoids also have effects unrelated to the regulation of blood sugar levels, including the suppression of the immune system and a potent anti-inflammatory effect. Cortisol reduces the capacity of osteoblasts to produce new bone tissue and decreases the absorption of calcium in the gastrointestinal tract. The adrenal gland secretes a basal level of cortisol but can also produce bursts of the hormone in response to adrenocorticotropic hormone (ACTH) from the anterior pituitary. Cortisol is not evenly released during the day – its concentrations in the blood are highest in the early morning and lowest in the evening as a result of the circadian rhythm of ACTH secretion. Cortisone is an inactive product of the action of the enzyme 11β-HSD on cortisol. The reaction catalyzed by 11β-HSD is reversible, which means that it can turn administered cortisone into cortisol, the biologically active hormone. Formation All corticosteroid hormones share cholesterol as a common precursor. Therefore, the first step in steroidogenesis is cholesterol uptake or synthesis. Cells that produce steroid hormones can acquire cholesterol through two paths. The main source is through dietary cholesterol transported via the blood as cholesterol esters within low density lipoproteins (LDL). LDL enters the cells through receptor-mediated endocytosis. The other source of cholesterol is synthesis in the cell's endoplasmic reticulum. Synthesis can compensate when LDL levels are abnormally low. In the lysosome, cholesterol esters are converted to free cholesterol, which is then used for steroidogenesis or stored in the cell. The initial part of conversion of cholesterol into steroid hormones involves a number of enzymes of the cytochrome P450 family that are located in the inner membrane of mitochondria. Transport of cholesterol from the outer to the inner membrane is facilitated by steroidogenic acute regulatory protein and is the rate-limiting step of steroid synthesis. The layers of the adrenal gland differ by function, with each layer having distinct enzymes that produce different hormones from a common precursor. The first enzymatic step in the production of all steroid hormones is cleavage of the cholesterol side chain, a reaction that forms pregnenolone as a product and is catalyzed by the enzyme P450scc, also known as cholesterol desmolase. After the production of pregnenolone, specific enzymes of each cortical layer further modify it. Enzymes involved in this process include both mitochondrial and microsomal P450s and hydroxysteroid dehydrogenases. Usually a number of intermediate steps in which pregnenolone is modified several times are required to form the functional hormones. Enzymes that catalyze reactions in these metabolic pathways are involved in a number of endocrine diseases. For example, the most common form of congenital adrenal hyperplasia develops as a result of deficiency of 21-hydroxylase, an enzyme involved in an intermediate step of cortisol production. Regulation Glucocorticoids are under the regulatory influence of the hypothalamic–pituitary–adrenal axis (HPA) axis. Glucocorticoid synthesis is stimulated by adrenocorticotropic hormone (ACTH), a hormone released into the bloodstream by the anterior pituitary. In turn, production of ACTH is stimulated by the presence of corticotropin-releasing hormone (CRH), which is released by neurons of the hypothalamus. ACTH acts on the adrenal cells first by increasing the levels of StAR within the cells, and then of all steroidogenic P450 enzymes. The HPA axis is an example of a negative feedback system, in which cortisol itself acts as a direct inhibitor of both CRH and ACTH synthesis. The HPA axis also interacts with the immune system through increased secretion of ACTH at the presence of certain molecules of the inflammatory response. Mineralocorticoid secretion is regulated mainly by the renin–angiotensin–aldosterone system (RAAS), the concentration of potassium, and to a lesser extent the concentration of ACTH. Sensors of blood pressure in the juxtaglomerular apparatus of the kidneys release the enzyme renin into the blood, which starts a cascade of reactions that lead to formation of angiotensin II. Angiotensin receptors in cells of the zona glomerulosa recognize the substance, and upon binding they stimulate the release of aldosterone. Androgens Cells in zona reticularis of the adrenal glands produce male sex hormones, or androgens, the most important of which is DHEA. In general, these hormones do not have an overall effect in the male body, and are converted to more potent androgens such as testosterone and DHT or to estrogens (female sex hormones) in the gonads, acting in this way as a metabolic intermediate. Catecholamines Primarily referred to in the United States as epinephrine and norepinephrine, adrenaline and noradrenaline are catecholamines, water-soluble compounds that have a structure made of a catechol group and an amine group. The adrenal glands are responsible for most of the adrenaline that circulates in the body, but only for a small amount of circulating noradrenaline. These hormones are released by the adrenal medulla, which contains a dense network of blood vessels. Adrenaline and noradrenaline act by interacting with adrenoreceptors throughout the body, with effects that include an increase in blood pressure and heart rate. Actions of adrenaline and noradrenaline are responsible for the fight or flight response, characterised by a quickening of breathing and heart rate, an increase in blood pressure, and constriction of blood vessels in many parts of the body. Formation Catecholamines are produced in chromaffin cells in the medulla of the adrenal gland, from tyrosine, a non-essential amino acid derived from food or produced from phenylalanine in the liver. The enzyme tyrosine hydroxylase converts tyrosine to L-DOPA in the first step of catecholamine synthesis. L-DOPA is then converted to dopamine before it can be turned into noradrenaline. In the cytosol, noradrenaline is converted to epinephrine by the enzyme phenylethanolamine N-methyltransferase (PNMT) and stored in granules. Glucocorticoids produced in the adrenal cortex stimulate the synthesis of catecholamines by increasing the levels of tyrosine hydroxylase and PNMT. Catecholamine release is stimulated by the activation of the sympathetic nervous system. Splanchnic nerves of the sympathetic nervous system innervate the medulla of the adrenal gland. When activated, it evokes the release of catecholamines from the storage granules by stimulating the opening of calcium channels in the cell membrane. Gene and protein expression The human genome includes approximately 20,000 protein coding genes and 70% of these genes are expressed in the normal adult adrenal glands. Only some 250 genes are more specifically expressed in the adrenal glands compared to other organs and tissues. The adrenal-gland-specific genes with the highest level of expression include members of the cytochrome P450 superfamily of enzymes. Corresponding proteins are expressed in the different compartments of the adrenal gland, such as CYP11A1, HSD3B2 and FDX1 involved in steroid hormone synthesis and expressed in cortical cell layers, and PNMT and DBH involved in noradrenaline and adrenaline synthesis and expressed in the medulla. Development The adrenal glands are composed of two heterogenous types of tissue. In the center is the adrenal medulla, which produces adrenaline and noradrenaline and releases them into the bloodstream, as part of the sympathetic nervous system. Surrounding the medulla is the cortex, which produces a variety of steroid hormones. These tissues come from different embryological precursors and have distinct prenatal development paths. The cortex of the adrenal gland is derived from mesoderm, whereas the medulla is derived from the neural crest, which is of ectodermal origin. The adrenal glands in a newborn baby are much larger as a proportion of the body size than in an adult. For example, at age three months the glands are four times the size of the kidneys. The size of the glands decreases relatively after birth, mainly because of shrinkage of the cortex. The cortex, which almost completely disappears by age 1, develops again from age 4–5. The glands weigh about at birth and develop to an adult weight of about each. In a fetus the glands are first detectable after the sixth week of development. Cortex Adrenal cortex tissue is derived from the intermediate mesoderm. It first appears 33 days after fertilisation, shows steroid hormone production capabilities by the eighth week and undergoes rapid growth during the first trimester of pregnancy. The fetal adrenal cortex is different from its adult counterpart, as it is composed of two distinct zones: the inner "fetal" zone, which carries most of the hormone-producing activity, and the outer "definitive" zone, which is in a proliferative phase. The fetal zone produces large amounts of adrenal androgens (male sex hormones) that are used by the placenta for estrogen biosynthesis. Cortical development of the adrenal gland is regulated mostly by ACTH, a hormone produced by the pituitary gland that stimulates cortisol synthesis. During midgestation, the fetal zone occupies most of the cortical volume and produces 100–200 mg/day of DHEA-S, an androgen and precursor of both androgens and estrogens (female sex hormones). Adrenal hormones, especially glucocorticoids such as cortisol, are essential for prenatal development of organs, particularly for the maturation of the lungs. The adrenal gland decreases in size after birth because of the rapid disappearance of the fetal zone, with a corresponding decrease in androgen secretion. Adrenarche During early childhood androgen synthesis and secretion remain low, but several years before puberty (from 6–8 years of age) changes occur in both anatomical and functional aspects of cortical androgen production that lead to increased secretion of the steroids DHEA and DHEA-S. These changes are part of a process called adrenarche, which has only been described in humans and some other primates. Adrenarche is independent of ACTH or gonadotropins and correlates with a progressive thickening of the zona reticularis layer of the cortex. Functionally, adrenarche provides a source of androgens for the development of axillary and pubic hair before the beginning of puberty. Medulla The adrenal medulla is derived from neural crest cells, which come from the ectoderm layer of the embryo. These cells migrate from their initial position and aggregate in the vicinity of the dorsal aorta, a primitive blood vessel, which activates the differentiation of these cells through the release of proteins known as BMPs. These cells then undergo a second migration from the dorsal aorta to form the adrenal medulla and other organs of the sympathetic nervous system. Cells of the adrenal medulla are called chromaffin cells because they contain granules that stain with chromium salts, a characteristic not present in all sympathetic organs. Glucocorticoids produced in the adrenal cortex were once thought to be responsible for the differentiation of chromaffin cells. More recent research suggests that BMP-4 secreted in adrenal tissue is the main responsible for this, and that glucocorticoids only play a role in the subsequent development of the cells. Clinical significance The normal function of the adrenal gland may be impaired by conditions such as infections, tumors, genetic disorders and autoimmune diseases, or as a side effect of medical therapy. These disorders affect the gland either directly (as with infections or autoimmune diseases) or as a result of the dysregulation of hormone production (as in some types of Cushing's syndrome) leading to an excess or insufficiency of adrenal hormones and the related symptoms. Corticosteroid overproduction Cushing's syndrome Cushing's syndrome is the manifestation of glucocorticoid excess. It can be the result of a prolonged treatment with glucocorticoids or be caused by an underlying disease which produces alterations in the HPA axis or the production of cortisol. Causes can be further classified into ACTH-dependent or ACTH-independent. The most common cause of endogenous Cushing's syndrome is a pituitary adenoma which causes an excessive production of ACTH. The disease produces a wide variety of signs and symptoms which include obesity, diabetes, increased blood pressure, excessive body hair (hirsutism), osteoporosis, depression, and most distinctively, stretch marks in the skin, caused by its progressive thinning. Primary aldosteronism When the zona glomerulosa produces excess aldosterone, the result is primary aldosteronism. Causes for this condition are bilateral hyperplasia (excessive tissue growth) of the glands, or aldosterone-producing adenomas (a condition called Conn's syndrome). Primary aldosteronism produces hypertension and electrolyte imbalance, increasing potassium depletion sodium retention. Adrenal insufficiency Adrenal insufficiency (the deficiency of glucocorticoids) occurs in about 5 in 10,000 in the general population. Diseases classified as primary adrenal insufficiency (including Addison's disease and genetic causes) directly affect the adrenal cortex. If a problem that affects the hypothalamic–pituitary–adrenal axis arises outside the gland, it is a secondary adrenal insufficiency. Addison's disease Addison's disease refers to primary hypoadrenalism, which is a deficiency in glucocorticoid and mineralocorticoid production by the adrenal gland. In the Western world, Addison's disease is most commonly an autoimmune condition, in which the body produces antibodies against cells of the adrenal cortex. Worldwide, the disease is more frequently caused by infection, especially from tuberculosis. A distinctive feature of Addison's disease is hyperpigmentation of the skin, which presents with other nonspecific symptoms such as fatigue. A complication seen in untreated Addison's disease and other types of primary adrenal insufficiency is the adrenal crisis, a medical emergency in which low glucocorticoid and mineralocorticoid levels result in hypovolemic shock and symptoms such as vomiting and fever. An adrenal crisis can progressively lead to stupor and coma. The management of adrenal crises includes the application of hydrocortisone injections. Secondary adrenal insufficiency In secondary adrenal insufficiency, a dysfunction of the hypothalamic–pituitary–adrenal axis leads to decreased stimulation of the adrenal cortex. Apart from suppression of the axis by glucocorticoid therapy, the most common cause of secondary adrenal insufficiency are tumors that affect the production of adrenocorticotropic hormone (ACTH) by the pituitary gland. This type of adrenal insufficiency usually does not affect the production of mineralocorticoids, which are under regulation of the renin–angiotensin system instead. Congenital adrenal hyperplasia Congenital adrenal hyperplasia is a family of congenital diseases in which mutations of enzymes that produce steroid hormones result in a glucocorticoid deficiency and malfunction of the negative feedback loop of the HPA axis. In the HPA axis, cortisol (a glucocorticoid) inhibits the release of CRH and ACTH, hormones that in turn stimulate corticosteroid synthesis. As cortisol cannot be synthesized, these hormones are released in high quantities and stimulate production of other adrenal steroids instead. The most common form of congenital adrenal hyperplasia is due to 21-hydroxylase deficiency. 21-hydroxylase is necessary for production of both mineralocorticoids and glucocorticoids, but not androgens. Therefore, ACTH stimulation of the adrenal cortex induces the release of excessive amounts of adrenal androgens, which can lead to the development of ambiguous genitalia and secondary sex characteristics. Adrenal tumors Adrenal tumors are commonly found as incidentalomas, unexpected asymptomatic tumors found during medical imaging. They are seen in around 3.4% of CT scans, and in most cases they are benign adenomas. Adrenal carcinomas are very rare, with an incidence of 1 case per million per year. Pheochromocytomas are tumors of the adrenal medulla that arise from chromaffin cells. They can produce a variety of nonspecific symptoms, which include headaches, sweating, anxiety and palpitations. Common signs include hypertension and tachycardia. Surgery, especially adrenal laparoscopy, is the most common treatment for small pheochromocytomas. History Bartolomeo Eustachi, an Italian anatomist, is credited with the first description of the adrenal glands in 1563–4. However, these publications were part of the papal library and did not receive public attention, which was first received with Caspar Bartholin the Elder's illustrations in 1611. The adrenal glands are named for their location relative to the kidneys. The term "adrenal" comes from Latin ad, "near", and ren, "kidney". Similarly, "suprarenal", as termed by Jean Riolan the Younger in 1629, is derived from the Latin supra, "above", and ren, "kidney", as well. The suprarenal nature of the glands was not truly accepted until the 19th century, as anatomists clarified the ductless nature of the glands and their likely secretory role – prior to this, there was some debate as to whether the glands were indeed suprarenal or part of the kidney. One of the most recognized works on the adrenal glands came in 1855 with the publication of On the Constitutional and Local Effects of Disease of the Suprarenal Capsule, by the English physician Thomas Addison. In his monography, Addison described what the French physician George Trousseau would later name Addison's disease, an eponym still used today for a condition of adrenal insufficiency and its related clinical manifestations. In 1894, English physiologists George Oliver and Edward Schafer studied the action of adrenal extracts and observed their pressor effects. In the following decades several physicians experimented with extracts from the adrenal cortex to treat Addison's disease. Edward Calvin Kendall, Philip Hench and Tadeusz Reichstein were then awarded the 1950 Nobel Prize in Physiology or Medicine for their discoveries on the structure and effects of the adrenal hormones.

A360 Media, LLC (branded a360media), formerly American Media, Inc. (AMI), is an American publisher of magazines, supermarket tabloids, and books based in New York City. Originally affiliated with only the National Enquirer, the media company's holdings expanded considerably in the 1990s and 2000s. In November 2010, American Media filed for Chapter 11 bankruptcy protection due to debts of nearly $1 billion, but has continued to buy and sell magazine brands since then. AMI has been in the news affiliated with accusations of catch and kill operations. On December 12, 2018, the U.S. Attorney's Office reported that AMI admitted to paying $150,000 to Karen McDougal in concert with a candidate's presidential campaign for the sole purpose of preventing damaging allegations prior to the 2016 US presidential election. According to its September 2018 non-prosecution agreement with Southern District of New York federal prosecutors, AMI "shall commit no crimes whatsoever" for three years, otherwise "A.M.I. shall thereafter be subject to prosecution for any federal criminal violation of which this office has knowledge." On April 10, 2019, Chatham Asset Management, which controls 80 percent of AMI's stock, forced AMI to sell the National Enquirer. This came after Chatham owner Anthony Melchiorre, who AMI has also relied on for survival, expressed dismay over the tabloid magazine's recent scandals involving hush money assistance to U.S. president Donald Trump's 2016 campaign and blackmail of Jeff Bezos. On April 18, 2019, AMI agreed to sell not only the National Enquirer, but two of its other publications, Globe and National Examiner, to Hudson News Distributors. In August 2020, Chatham Asset Management, AMI's owning holding company, announced it would merge AMI with Accelerate 360, a wholesale distribution company it also owned. As part of the merger, AMI was officially renamed A360 on October 1. In February 2023, A360media agreed to sell the National Enquirer to VVIP Ventures, a joint venture of the digital media company Vinco Ventures and a new company set up for the purchase, Icon Publishing. History The modern American Media came into being after Generoso Pope Jr., longtime owner of the National Enquirer, died in 1988, and his tabloids came under new ownership. American tabloids began consolidating in 1990, when American Media bought Star from Rupert Murdoch. The purchase of Globe Communications (owner of the Globe and the National Examiner) followed nine years later. Roger Altman, through Evercore Partners, bought a controlling stake in American Media in 1999. American Media is not to be confused with American Media Distribution, the international news coverage firm. American Media's former corporate headquarters in Boca Raton, Florida, figured prominently in news headlines in late 2001, after an anthrax attack was perpetrated on the company and other media outlets. Since then the corporate headquarters have moved to New York City at 1 Park Avenue in Manhattan, before moving to the Financial District to the former JP Morgan Chase headquarters at 4 New York Plaza. That building was severely damaged by Hurricane Sandy but reopened in February 2013. AMI continued to expand after it bought Joe Weider's Weider Publications in 2002. Joe Weider continued to manage control of his magazines under AMI's Weider Publications subsidiary until his death in March 2013. American Media also owns Distribution Services, an in-store magazine merchandising company. In fall 2002, it launched the book-publishing imprint, AMI Books. 2010s: Bankruptcy and continued acquisitions In 2009, American Media was taken over by its bondholders to keep it out of bankruptcy. In November 2010, American Media filed for Chapter 11 bankruptcy protection due to nearly $1 billion in debt, and assets of less than $50,000. Its subsidiary, American Media Operations Inc., listed assets of $100 to $500 million and debt of over $1 billion. It exited in December. In May 2014, American Media announced a decision to shift the headquarters of the National Enquirer from Florida, where it had been located since 1971, back to New York City, where it originally began as The New York Enquirer in 1926. In August 2014, American Media was acquired by Chatham Asset Management and Omega Charitable Partnership. In 2015, American Media sold Shape, Natural Health, and Fit Pregnancy to Meredith. In 2016, Pecker revealed to the Toronto Star that AMI now relied on support from Chatham Asset Management and its owner Anthony Melchiorre. The $4 billion hedge fund owns 80 percent of AMI's stock. In March 2017, American Media acquired Us Weekly from Wenner Media for a reported $100 million. Three months later, in June 2017, American Media also acquired Men's Journal from Wenner Media. In June 2018, American Media acquired 13 brands from Bauer Media Group including In Touch Weekly, Life & Style and Closer to add to their celebrity portfolio. They also acquired Bauer Media's kids group including J-14 and Girl's World. In February 2019, American Media acquired TEN's adventure sports properties. In April 2019, the National Enquirer was reported to be up for sale and likely to be sold within days. The company stated that it had shifted its emphasis away from tabloids to its "glossy" magazines such as Us Weekly and Men's Journal. This came following pressure from Chatham owner Anthony Melchiorre, who expressed disapproval of the Enquirer's style of journalism. On April 18, 2019, AMI accepted an offer from Hudson News Distributors head James Cohen and agreed to sell not only the National Enquirer, but also Globe and The Examiner to Hudson News Distributors for $100 million. At the time the sales were announced, AMI was approximately $355 million in debt. In 2022, A360 acquired single issue magazine publisher Centennial Media. Also in 2022, A360 sold Men's Journal and the Adventure Sports Network properties to The Arena Group. "Catch-and-kill" scandals related to Donald Trump In late 2015, AMI paid $30,000 to Dino Sajudin, a doorman at Trump Tower, to obtain the rights to his story in which he alleged Donald Trump had an affair in the 1980s that resulted in the birth of a child. Sajudin in April 2018 identified the woman as Trump's former housekeeper. AMI reporters were given the names of the woman and the alleged child, while Sajudin passed a lie detector test when testifying that he had heard the story from others. Shortly after the payment was made, Pecker ordered the reporters to drop the story. In April 2018, AMI chief content officer Dylan Howard denied the story was "spiked" in a so-called "catch and kill" operation, insisting that AMI did not run the story because Sajudin's story lacked credibility. On August 24, 2018, after AMI had released Sajudin from the contract, CNN obtained a copy of it and published excerpts. The contract instructed Sajudin to provide "information regarding Donald Trump's illegitimate child," but did not contain further specifics of Sajudin's story. Karen McDougal In 2016, AMI paid Playboy model Karen McDougal $150,000 for exclusive rights to her allegations of a ten-month affair with Donald Trump—which she claimed happened in 2006–2007, when he was already married to Melania—but AMI never published the story. AMI publicly acknowledged having made the payment after The Wall Street Journal revealed it days before the 2016 presidential election, but AMI denied that its purpose had been to "kill damaging stories about" Trump; instead, AMI claimed it had paid only for "exclusive life rights to any relationship [McDougal] has had with a then-married man" and "two years' worth of her fitness columns and magazine covers." In March 2018, McDougal filed a lawsuit to invalidate the non-disclosure agreement she had with AMI. A month later, AMI settled with McDougal, allowing her to speak about the alleged affair. In August 2018, it was reported that AMI CEO/Chairman David Pecker and AMI chief content officer Dylan Howard were granted witness immunity in exchange for their testimony regarding hush money payments made by Donald Trump's then-personal lawyer, Michael Cohen, in an attempt to influence the 2016 presidential election. On December 12, 2018, the U.S. Attorney's Office announced its agreement with AMI. "AMI admitted that it made the $150,000 payment in concert with a candidate's presidential campaign," the press release said, so that Karen McDougal wouldn't "publicize damaging allegations about the candidate before the 2016 presidential election. AMI further admitted that its principal purpose in making the payment was to suppress the woman's story so as to prevent it from influencing the election." As a result of this agreement, AMI would not face prosecution and agreed to provide extensive assistance to prosecutors about the involvement of Trump and other politicians with the company. The same press release also revealed that Michael Cohen had been sentenced to three years in prison for various crimes, including the $150,000 campaign finance violation—the facilitation of the payment to McDougal—to which he pled guilty on August 21, 2018. AMI agreed to pay the Federal Election Commission a $187,500 fine in June 2021. Jeff Bezos blackmail In January 2019, the National Enquirer broke a story about the extramarital affair of Amazon founder and Washington Post owner Jeff Bezos with Lauren Sánchez. Bezos began investigating how and why the information had been leaked to the National Enquirer. President Trump has long expressed displeasure with Bezos, and Trump's irritation may have increased due to the Washington Post's critical coverage of the murder (and the subsequent cover-up) of one of its reporters, Jamal Khashoggi. This, Bezos suspects, may have been the political motivation for someone to leak his affair to the tabloid. On February 7, 2019, Bezos shared emails that he had received the previous day in which AMI sought a public statement from him and his lawyer "affirming that they have no knowledge or basis for suggesting that AM's coverage [of the sexual affair] was politically motivated or influenced by political forces, and an agreement that they will cease referring to such a possibility." AMI chief content officer Dylan Howard and his lawyer Jon Fine threatened Bezos, saying that if Bezos did not promptly meet their demands, AMI would publish selfies and sexts sent between Bezos and his girlfriend. Bezos wrote that he would refuse to make this "specific lie" or to otherwise participate in this blackmail bargain that "no real journalists [would] ever propose." "Of course I don't want personal photos published," Bezos added, but he said he chooses to "stand up, roll this log over, and see what crawls out." That same day, The Washington Post published an article on the matter, quoting a former federal prosecutor who speculated that this news could undermine AMI's recent deal with the government. If prosecutors decide they must file new criminal charges against AMI, the government may not be able "to continue to use them [AMI] to assist other ongoing investigations," said Robert Mintz. Lauren Sanchez's brother, Michael Sanchez, an ardent Trump supporter, stated he was told by multiple AMI employees that the Enquirer set out to do "a takedown to make Trump happy" and The Daily Beast reported seeing documents showing that Sanchez believed the Bezos story was run with "President Trump's knowledge and appreciation."

The actinide () or actinoid () series encompasses the 14 metallic chemical elements with atomic numbers from 89 to 102, actinium through nobelium. The actinide series derives its name from the first element in the series, actinium. The informal chemical symbol An is used in general discussions of actinide chemistry to refer to any actinide. The 1985 IUPAC Red Book recommends that actinoid be used rather than actinide, since the suffix -ide normally indicates a negative ion. However, owing to widespread current use, actinide is still allowed. Since actinoid literally means actinium-like (cf. humanoid or android), it has been argued for semantic reasons that actinium cannot logically be an actinoid, but IUPAC acknowledges its inclusion based on common usage. All the actinides are f-block elements. Lawrencium is sometimes considered one as well, despite being a d-block element and a transition metal. The series mostly corresponds to the filling of the 5f electron shell, although in the ground state many have anomalous configurations involving the filling of the 6d shell due to interelectronic repulsion. In comparison with the lanthanides, also mostly f-block elements, the actinides show much more variable valence. They all have very large atomic and ionic radii and exhibit an unusually large range of physical properties. While actinium and the late actinides (from americium onwards) behave similarly to the lanthanides, the elements thorium, protactinium, and uranium are much more similar to transition metals in their chemistry, with neptunium and plutonium occupying an intermediate position. All actinides are radioactive and release energy upon radioactive decay; naturally occurring uranium and thorium, and synthetically produced plutonium are the most abundant actinides on Earth. These are used in nuclear reactors and nuclear weapons. Uranium and thorium also have diverse current or historical uses, and americium is used in the ionization chambers of most modern smoke detectors. Of the actinides, primordial thorium and uranium occur naturally in substantial quantities. The radioactive decay of uranium produces transient amounts of actinium and protactinium, and atoms of neptunium and plutonium are occasionally produced from transmutation reactions in uranium ores. The other actinides are purely synthetic elements. Nuclear weapons tests have released at least six actinides heavier than plutonium into the environment; analysis of debris from a 1952 hydrogen bomb explosion showed the presence of americium, curium, berkelium, californium, einsteinium and fermium. In presentations of the periodic table, the f-block elements are customarily shown as two additional rows below the main body of the table. This convention is entirely a matter of aesthetics and formatting practicality; a rarely used wide-formatted periodic table inserts the 4f and 5f series in their proper places, as parts of the table's sixth and seventh rows (periods). Discovery, isolation and synthesis Like the lanthanides, the actinides form a family of elements with similar properties. Within the actinides, there are two overlapping groups: transuranium elements, which follow uranium in the periodic table; and transplutonium elements, which follow plutonium. Compared to the lanthanides, which (except for promethium) are found in nature in appreciable quantities, most actinides are rare. Most do not occur in nature, and of those that do, only thorium and uranium do so in more than trace quantities. The most abundant or easily synthesized actinides are uranium and thorium, followed by plutonium, americium, actinium, protactinium, neptunium, and curium. The existence of transuranium elements was suggested in 1934 by Enrico Fermi, based on his experiments. However, even though four actinides were known by that time, it was not yet understood that they formed a family similar to lanthanides. The prevailing view that dominated early research into transuranics was that they were regular elements in the 7th period, with thorium, protactinium and uranium corresponding to 6th-period hafnium, tantalum and tungsten, respectively. Synthesis of transuranics gradually undermined this point of view. By 1944, an observation that curium failed to exhibit oxidation states above 4 (whereas its supposed 6th period homolog, platinum, can reach oxidation state of 6) prompted Glenn Seaborg to formulate an "actinide hypothesis". Studies of known actinides and discoveries of further transuranic elements provided more data in support of this position, but the phrase "actinide hypothesis" (the implication being that a "hypothesis" is something that has not been decisively proven) remained in active use by scientists through the late 1950s. At present, there are two major methods of producing isotopes of transplutonium elements: (1) irradiation of the lighter elements with neutrons; (2) irradiation with accelerated charged particles. The first method is more important for applications, as only neutron irradiation using nuclear reactors allows the production of sizeable amounts of synthetic actinides; however, it is limited to relatively light elements. The advantage of the second method is that elements heavier than plutonium, as well as neutron-deficient isotopes, can be obtained, which are not formed during neutron irradiation. In 1962–1966, there were attempts in the United States to produce transplutonium isotopes using a series of six underground nuclear explosions. Small samples of rock were extracted from the blast area immediately after the test to study the explosion products, but no isotopes with mass number greater than 257 could be detected, despite predictions that such isotopes would have relatively long half-lives of α-decay. This non-observation was attributed to spontaneous fission owing to the large speed of the products and to other decay channels, such as neutron emission and nuclear fission. From actinium to uranium Uranium and thorium were the first actinides discovered. Uranium was identified in 1789 by the German chemist Martin Heinrich Klaproth in pitchblende ore. He named it after the planet Uranus, which had been discovered eight years earlier. Klaproth was able to precipitate a yellow compound (likely sodium diuranate) by dissolving pitchblende in nitric acid and neutralizing the solution with sodium hydroxide. He then reduced the obtained yellow powder with charcoal, and extracted a black substance that he mistook for metal. Sixty years later, the French scientist Eugène-Melchior Péligot identified it as uranium oxide. He also isolated the first sample of uranium metal by heating uranium tetrachloride with metallic potassium. The atomic mass of uranium was then calculated as 120, but Dmitri Mendeleev in 1872 corrected it to 240 using his periodicity laws. This value was confirmed experimentally in 1882 by K. Zimmerman. Thorium oxide was discovered by Friedrich Wöhler in the mineral thorianite, which was found in Norway (1827). Jöns Jacob Berzelius characterized this material in more detail in 1828. By reduction of thorium tetrachloride with potassium, he isolated the metal and named it thorium after the Norse god of thunder and lightning Thor. The same isolation method was later used by Péligot for uranium. Actinium was discovered in 1899 by André-Louis Debierne, an assistant of Marie Curie, in the pitchblende waste left after removal of radium and polonium. He described the substance (in 1899) as similar to titanium and (in 1900) as similar to thorium. The discovery of actinium by Debierne was however questioned in 1971 and 2000, arguing that Debierne's publications in 1904 contradicted his earlier work of 1899–1900. This view instead credits the 1902 work of Friedrich Oskar Giesel, who discovered a radioactive element named emanium that behaved similarly to lanthanum. The name actinium comes from the , meaning beam or ray. This metal was discovered not by its own radiation but by the radiation of the daughter products. Owing to the close similarity of actinium and lanthanum and low abundance, pure actinium could only be produced in 1950. The term actinide was probably introduced by Victor Goldschmidt in 1937. Protactinium was possibly isolated in 1900 by William Crookes. It was first identified in 1913, when Kasimir Fajans and Oswald Helmuth Göhring encountered the short-lived isotope 234mPa (half-life 1.17 minutes) during their studies of the 238U decay. They named the new element brevium (from Latin brevis meaning brief); the name was changed to protoactinium (from Greek πρῶτος + ἀκτίς meaning "first beam element") in 1918 when two groups of scientists, led by the Austrian Lise Meitner and Otto Hahn of Germany and Frederick Soddy and John Cranston of Great Britain, independently discovered the much longer-lived 231Pa. The name was shortened to protactinium in 1949. This element was little characterized until 1960, when A. G. Maddock and his co-workers in the U.K. isolated 130 grams of protactinium from 60 tonnes of waste left after extraction of uranium from its ore. Neptunium and above Neptunium (named for the planet Neptune, the next planet out from Uranus, after which uranium was named) was discovered by Edwin McMillan and Philip H. Abelson in 1940 in Berkeley, California. They produced the 239Np isotope (half-life = 2.4 days) by bombarding uranium with slow neutrons. It was the first transuranium element produced synthetically. Transuranium elements do not occur in sizeable quantities in nature and are commonly synthesized via nuclear reactions conducted with nuclear reactors. For example, under irradiation with reactor neutrons, uranium-238 partially converts to plutonium-239: This synthesis reaction was used by Fermi and his collaborators in their design of the reactors located at the Hanford Site, which produced significant amounts of plutonium-239 for the nuclear weapons of the Manhattan Project and the United States' post-war nuclear arsenal. Actinides with the highest mass numbers are synthesized by bombarding uranium, plutonium, curium and californium with ions of nitrogen, oxygen, carbon, neon or boron in a particle accelerator. Thus nobelium was produced by bombarding uranium-238 with neon-22 as _{92}^{238}U + _{10}^{22}Ne -> _{102}^{256}No + 4_0^1n. The first isotopes of transplutonium elements, americium-241 and curium-242, were synthesized in 1944 by Glenn T. Seaborg, Ralph A. James and Albert Ghiorso. Curium-242 was obtained by bombarding plutonium-239 with 32-MeV α-particles _{94}^{239}Pu + _2^4He -> _{96}^{242}Cm + _0^1n. The americium-241 and curium-242 isotopes also were produced by irradiating plutonium in a nuclear reactor. The latter element was named after Marie Curie and her husband Pierre who are noted for discovering radium and for their work in radioactivity. Bombarding curium-242 with α-particles resulted in an isotope of californium 245Cf (1950), and a similar procedure yielded in 1949 berkelium-243 from americium-241. The new elements were named after Berkeley, California, by analogy with its lanthanide homologue terbium, which was named after the village of Ytterby in Sweden. In 1945, B. B. Cunningham obtained the first bulk chemical compound of a transplutonium element, namely americium hydroxide. Over the few years, milligram quantities of americium and microgram amounts of curium were accumulated that allowed production of isotopes of berkelium (Thomson, 1949) and californium (Thomson, 1950). Sizeable amounts of these elements were produced in 1958 (Burris B. Cunningham and Stanley G. Thomson), and the first californium compound (0.3 µg of CfOCl) was obtained in 1960 by B. B. Cunningham and J. C. Wallmann. Einsteinium and fermium were identified in 1952–1953 in the fallout from the "Ivy Mike" nuclear test (1 November 1952), the first successful test of a hydrogen bomb. Instantaneous exposure of uranium-238 to a large neutron flux resulting from the explosion produced heavy isotopes of uranium, including uranium-253 and uranium-255, and their β-decay yielded einsteinium-253 and fermium-255. The discovery of the new elements and the new data on neutron capture were initially kept secret on the orders of the US military until 1955 due to Cold War tensions. Nevertheless, the Berkeley team were able to prepare einsteinium and fermium by civilian means, through the neutron bombardment of plutonium-239, and published this work in 1954 with the disclaimer that it was not the first studies that had been carried out on those elements. The "Ivy Mike" studies were declassified and published in 1955. The first significant (submicrograms) amounts of einsteinium were produced in 1961 by Cunningham and colleagues, but this has not been done for fermium yet. The first isotope of mendelevium, 256Md (half-life 87 min), was synthesized by Albert Ghiorso, Glenn T. Seaborg, Gregory R. Choppin, Bernard G. Harvey and Stanley G. Thompson when they bombarded an 253Es target with alpha particles in the 60-inch cyclotron of Berkeley Radiation Laboratory; this was the first isotope of any element to be synthesized one atom at a time. There were several attempts to obtain isotopes of nobelium by Swedish (1957) and American (1958) groups, but the first reliable result was the synthesis of 256No by the Russian group (Georgy Flyorov et al.) in 1965, as acknowledged by the IUPAC in 1992. In their experiments, Flyorov et al. bombarded uranium-238 with neon-22. In 1961, Ghiorso et al. obtained the first isotope of lawrencium by irradiating californium (mostly californium-252) with boron-10 and boron-11 ions. The mass number of this isotope was not clearly established (possibly 258 or 259) at the time. In 1965, 256Lr was synthesized by Flyorov et al. from 243Am and 18O. Thus IUPAC recognized the nuclear physics teams at Dubna and Berkeley as the co-discoverers of lawrencium. Isotopes 32 isotopes of actinium and eight excited isomeric states of some of its nuclides were identified by 2016. Three isotopes, 225Ac, 227Ac and 228Ac, were found in nature and the others were produced in the laboratory; only the three natural isotopes are used in applications. Actinium-225 is a member of the radioactive neptunium series; it was first discovered in 1947 as a decay product of uranium-233, it is an α-emitter with a half-life of 10 days. Actinium-225 is less available than actinium-228, but is more promising in radiotracer applications. Actinium-227 (half-life 21.77 years) occurs in all uranium ores, but in small quantities. One gram of uranium (in radioactive equilibrium) contains only 2 gram of 227Ac. Actinium-228 is a member of the radioactive thorium series formed by the decay of 228Ra; it is a β− emitter with a half-life of 6.15 hours. In one tonne of thorium there is 5 gram of 228Ac. It was discovered by Otto Hahn in 1906. There are 31 known isotopes of thorium ranging in mass number from 208 to 238. Of these, the longest-lived is 232Th, whose half-life of means that it still exists in nature as a primordial nuclide. The next longest-lived is 230Th, an intermediate decay product of 238U with a half-life of 75,400 years. Several other thorium isotopes have half-lives over a day; all of these are also transient in the decay chains of 232Th, 235U, and 238U. 28 isotopes of protactinium are known with mass numbers 212–239 as well as three excited isomeric states. Only 231Pa and 234Pa have been found in nature. All the isotopes have short lifetimes, except for protactinium-231 (half-life 32,760 years). The most important isotopes are 231Pa and 233Pa, which is an intermediate product in obtaining uranium-233 and is the most affordable among artificial isotopes of protactinium. 233Pa has convenient half-life and energy of γ-radiation, and thus was used in most studies of protactinium chemistry. Protactinium-233 is a β-emitter with a half-life of 26.97 days. There are 26 known isotopes of uranium, having mass numbers 215–242 (except 220 and 241). Three of them, 234U, 235U and 238U, are present in appreciable quantities in nature. Among others, the most important is 233U, which is a final product of transformation of 232Th irradiated by slow neutrons. 233U has a much higher fission efficiency by low-energy (thermal) neutrons, compared e.g. with 235U. Most uranium chemistry studies were carried out on uranium-238 owing to its long half-life of 4.4 years. There are 24 isotopes of neptunium with mass numbers of 219, 220, and 223–244; they are all highly radioactive. The most popular among scientists are long-lived 237Np (t1/2 = 2.20 years) and short-lived 239Np, 238Np (t1/2 ~ 2 days). There are 20 known isotopes of plutonium, having mass numbers 228–247. The most stable isotope of plutonium is 244Pu with half-life of 8.13 years. Eighteen isotopes of americium are known with mass numbers from 229 to 247 (with the exception of 231). The most important are 241Am and 243Am, which are alpha-emitters and also emit soft, but intense γ-rays; both of them can be obtained in an isotopically pure form. Chemical properties of americium were first studied with 241Am, but later shifted to 243Am, which is almost 20 times less radioactive. The disadvantage of 243Am is production of the short-lived daughter isotope 239Np, which has to be considered in the data analysis. Among 19 isotopes of curium, ranging in mass number from 233 to 251, the most accessible are 242Cm and 244Cm; they are α-emitters, but with much shorter lifetime than the americium isotopes. These isotopes emit almost no γ-radiation, but undergo spontaneous fission with the associated emission of neutrons. More long-lived isotopes of curium (245–248Cm, all α-emitters) are formed as a mixture during neutron irradiation of plutonium or americium. Upon short irradiation, this mixture is dominated by 246Cm, and then 248Cm begins to accumulate. Both of these isotopes, especially 248Cm, have a longer half-life (3.48 years) and are much more convenient for carrying out chemical research than 242Cm and 244Cm, but they also have a rather high rate of spontaneous fission. 247Cm has the longest lifetime among isotopes of curium (1.56 years), but is not formed in large quantities because of the strong fission induced by thermal neutrons. Seventeen isotopes of berkelium were identified with mass numbers 233–234, 236, 238, and 240–252. Only 249Bk is available in large quantities; it has a relatively short half-life of 330 days and emits mostly soft β-particles, which are inconvenient for detection. Its alpha radiation is rather weak (1.45% with respect to β-radiation), but is sometimes used to detect this isotope. 247Bk is an alpha-emitter with a long half-life of 1,380 years, but it is hard to obtain in appreciable quantities; it is not formed upon neutron irradiation of plutonium because of the β-stability of isotopes of curium isotopes with mass number below 248. The 20 isotopes of californium with mass numbers 237–256 are formed in nuclear reactors; californium-253 is a β-emitter and the rest are α-emitters. The isotopes with even mass numbers (250Cf, 252Cf and 254Cf) have a high rate of spontaneous fission, especially 254Cf of which 99.7% decays by spontaneous fission. Californium-249 has a relatively long half-life (352 years), weak spontaneous fission and strong γ-emission that facilitates its identification. 249Cf is not formed in large quantities in a nuclear reactor because of the slow β-decay of the parent isotope 249Bk and a large cross section of interaction with neutrons, but it can be accumulated in the isotopically pure form as the β-decay product of (pre-selected) 249Bk. Californium produced by reactor-irradiation of plutonium mostly consists of 250Cf and 252Cf, the latter being predominant for large neutron fluences, and its study is hindered by the strong neutron radiation. Among the 18 known isotopes of einsteinium with mass numbers from 240 to 257, the most affordable is 253Es. It is an α-emitter with a half-life of 20.47 days, a relatively weak γ-emission and small spontaneous fission rate as compared with the isotopes of californium. Prolonged neutron irradiation also produces a long-lived isotope 254Es (t1/2 = 275.5 days). Twenty isotopes of fermium are known with mass numbers of 241–260. 254Fm, 255Fm and 256Fm are α-emitters with a short half-life (hours), which can be isolated in significant amounts. 257Fm (t1/2 = 100 days) can accumulate upon prolonged and strong irradiation. All these isotopes are characterized by high rates of spontaneous fission. Among the 17 known isotopes of mendelevium (mass numbers from 244 to 260), the most studied is 256Md, which mainly decays through the electron capture (α-radiation is ≈10%) with the half-life of 77 minutes. Another alpha emitter, 258Md, has a half-life of 53 days. Both these isotopes are produced from rare einsteinium (253Es and 255Es respectively), that therefore limits their availability. Long-lived isotopes of nobelium and isotopes of lawrencium (and of heavier elements) have relatively short half-lives. For nobelium, 11 isotopes are known with mass numbers 250–260 and 262. The chemical properties of nobelium and lawrencium were studied with 255No (t1/2 = 3 min) and 256Lr (t1/2 = 35 s). The longest-lived nobelium isotope, 259No, has a half-life of approximately 1 hour. Lawrencium has 13 known isotopes with mass numbers 251–262 and 266. The most stable of them all is 266Lr with a half life of 11 hours. Among all of these, the only isotopes that occur in sufficient quantities in nature to be detected in anything more than traces and have a measurable contribution to the atomic weights of the actinides are the primordial 232Th, 235U, and 238U, and three long-lived decay products of natural uranium, 230Th, 231Pa, and 234U. Natural thorium consists of 0.02(2)% 230Th and 99.98(2)% 232Th; natural protactinium consists of 100% 231Pa; and natural uranium consists of 0.0054(5)% 234U, 0.7204(6)% 235U, and 99.2742(10)% 238U. Formation in nuclear reactors The figure buildup of actinides is a table of nuclides with the number of neutrons on the horizontal axis (isotopes) and the number of protons on the vertical axis (elements). The red dot divides the nuclides in two groups, so the figure is more compact. Each nuclide is represented by a square with the mass number of the element and its half-life. Naturally existing actinide isotopes (Th, U) are marked with a bold border, alpha emitters have a yellow colour, and beta emitters have a blue colour. Pink indicates electron capture (236Np), whereas white stands for a long-lasting metastable state (242Am). The formation of actinide nuclides is primarily characterised by: Neutron capture reactions (n,γ), which are represented in the figure by a short right arrow. The (n,2n) reactions and the less frequently occurring (γ,n) reactions are also taken into account, both of which are marked by a short left arrow. Even more rarely and only triggered by fast neutrons, the (n,3n) reaction occurs, which is represented in the figure with one example, marked by a long left arrow. In addition to these neutron- or gamma-induced nuclear reactions, the radioactive conversion of actinide nuclides also affects the nuclide inventory in a reactor. These decay types are marked in the figure by diagonal arrows. The beta-minus decay, marked with an arrow pointing up-left, plays a major role for the balance of the particle densities of the nuclides. Nuclides decaying by positron emission (beta-plus decay) or electron capture (ϵ) do not occur in a nuclear reactor except as products of knockout reactions; their decays are marked with arrows pointing down-right. Due to the long half-lives of the given nuclides, alpha decay plays almost no role in the formation and decay of the actinides in a power reactor, as the residence time of the nuclear fuel in the reactor core is rather short (a few years). Exceptions are the two relatively short-lived nuclides 242Cm (T1/2 = 163 d) and 236Pu (T1/2 = 2.9 y). Only for these two cases, the α decay is marked on the nuclide map by a long arrow pointing down-left. A few long-lived actinide isotopes, such as 244Pu and 250Cm, cannot be produced in reactors because neutron capture does not happen quickly enough to bypass the short-lived beta-decaying nuclides 243Pu and 249Cm; they can however be generated in nuclear explosions, which have much higher neutron fluxes. Distribution in nature Thorium and uranium are the most abundant actinides in nature with the respective mass concentrations of 16 ppm and 4 ppm. Uranium mostly occurs in the Earth's crust as a mixture of its oxides in the mineral uraninite, which is also called pitchblende because of its black color. There are several dozens of other uranium minerals such as carnotite (KUO2VO4·3H2O) and autunite (Ca(UO2)2(PO4)2·nH2O). The isotopic composition of natural uranium is 238U (relative abundance 99.2742%), 235U (0.7204%) and 234U (0.0054%); of these 238U has the largest half-life of 4.51 years. The worldwide production of uranium in 2009 amounted to 50,572 tonnes, of which 27.3% was mined in Kazakhstan. Other important uranium mining countries are Canada (20.1%), Australia (15.7%), Namibia (9.1%), Russia (7.0%), and Niger (6.4%). The most abundant thorium minerals are thorianite (), thorite () and monazite, (). Most thorium minerals contain uranium and vice versa; and they all have significant fraction of lanthanides. Rich deposits of thorium minerals are located in the United States (440,000 tonnes), Australia and India (~300,000 tonnes each) and Canada (~100,000 tonnes). The abundance of actinium in the Earth's crust is only about 5%. Actinium is mostly present in uranium-containing, but also in other minerals, though in much smaller quantities. The content of actinium in most natural objects corresponds to the isotopic equilibrium of parent isotope 235U, and it is not affected by the weak Ac migration. Protactinium is more abundant (10−12%) in the Earth's crust than actinium. It was discovered in the uranium ore in 1913 by Fajans and Göhring. As actinium, the distribution of protactinium follows that of 235U. The half-life of the longest-lived isotope of neptunium, 237Np, is negligible compared to the age of the Earth. Thus neptunium is present in nature in negligible amounts produced as intermediate decay products of other isotopes. Traces of plutonium in uranium minerals were first found in 1942, and the more systematic results on 239Pu are summarized in the table (no other plutonium isotopes could be detected in those samples). The upper limit of abundance of the longest-living isotope of plutonium, 244Pu, is 3%. Plutonium could not be detected in samples of lunar soil. Owing to its scarcity in nature, most plutonium is produced synthetically. Extraction Owing to the low abundance of actinides, their extraction is a complex, multistep process. Fluorides of actinides are usually used because they are insoluble in water and can be easily separated with redox reactions. Fluorides are reduced with calcium, magnesium or barium: Among the actinides, thorium and uranium are the easiest to isolate. Thorium is extracted mostly from monazite: thorium pyrophosphate (ThP2O7) is reacted with nitric acid, and the produced thorium nitrate treated with tributyl phosphate. Rare-earth impurities are separated by increasing the pH in sulfate solution. In another extraction method, monazite is decomposed with a 45% aqueous solution of sodium hydroxide at 140 °C. Mixed metal hydroxides are extracted first, filtered at 80 °C, washed with water and dissolved with concentrated hydrochloric acid. Next, the acidic solution is neutralized with hydroxides to pH = 5.8 that results in precipitation of thorium hydroxide (Th(OH)4) contaminated with ~3% of rare-earth hydroxides; the rest of rare-earth hydroxides remains in solution. Thorium hydroxide is dissolved in an inorganic acid and then purified from the rare earth elements. An efficient method is the dissolution of thorium hydroxide in nitric acid, because the resulting solution can be purified by extraction with organic solvents: Th(OH)4 + 4 HNO3 → Th(NO3)4 + 4 H2O Metallic thorium is separated from the anhydrous oxide, chloride or fluoride by reacting it with calcium in an inert atmosphere: ThO2 + 2 Ca → 2 CaO + Th Sometimes thorium is extracted by electrolysis of a fluoride in a mixture of sodium and potassium chloride at 700–800 °C in a graphite crucible. Highly pure thorium can be extracted from its iodide with the crystal bar process. Uranium is extracted from its ores in various ways. In one method, the ore is burned and then reacted with nitric acid to convert uranium into a dissolved state. Treating the solution with a solution of tributyl phosphate (TBP) in kerosene transforms uranium into an organic form UO2(NO3)2(TBP)2. The insoluble impurities are filtered and the uranium is extracted by reaction with hydroxides as (NH4)2U2O7 or with hydrogen peroxide as UO4·2H2O. When the uranium ore is rich in such minerals as dolomite, magnesite, etc., those minerals consume much acid. In this case, the carbonate method is used for uranium extraction. Its main component is an aqueous solution of sodium carbonate, which converts uranium into a complex [UO2(CO3)3]4−, which is stable in aqueous solutions at low concentrations of hydroxide ions. The advantages of the sodium carbonate method are that the chemicals have low corrosivity (compared to nitrates) and that most non-uranium metals precipitate from the solution. The disadvantage is that tetravalent uranium compounds precipitate as well. Therefore, the uranium ore is treated with sodium carbonate at elevated temperature and under oxygen pressure: 2 UO2 + O2 + 6 → 2 [UO2(CO3)3]4− This equation suggests that the best solvent for the uranium carbonate processing is a mixture of carbonate with bicarbonate. At high pH, this results in precipitation of diuranate, which is treated with hydrogen in the presence of nickel yielding an insoluble uranium tetracarbonate. Another separation method uses polymeric resins as a polyelectrolyte. Ion exchange processes in the resins result in separation of uranium. Uranium from resins is washed with a solution of ammonium nitrate or nitric acid that yields uranyl nitrate, UO2(NO3)2·6H2O. When heated, it turns into UO3, which is converted to UO2 with hydrogen: UO3 + H2 → UO2 + H2O Reacting uranium dioxide with hydrofluoric acid changes it to uranium tetrafluoride, which yields uranium metal upon reaction with magnesium metal: 4 HF + UO2 → UF4 + 2 H2O To extract plutonium, neutron-irradiated uranium is dissolved in nitric acid, and a reducing agent (FeSO4, or H2O2) is added to the resulting solution. This addition changes the oxidation state of plutonium from +6 to +4, while uranium remains in the form of uranyl nitrate (UO2(NO3)2). The solution is treated with a reducing agent and neutralized with ammonium carbonate to pH = 8 that results in precipitation of Pu4+ compounds. In another method, Pu4+ and are first extracted with tributyl phosphate, then reacted with hydrazine washing out the recovered plutonium. The major difficulty in separation of actinium is the similarity of its properties with those of lanthanum. Thus actinium is either synthesized in nuclear reactions from isotopes of radium or separated using ion-exchange procedures. Properties Actinides have similar properties to lanthanides. The 6d and 7s electronic shells are filled in actinium and thorium, and the 5f shell is being filled with further increase in atomic number; the 4f shell is filled in the lanthanides. The first experimental evidence for the filling of the 5f shell in actinides was obtained by McMillan and Abelson in 1940. As in lanthanides (see lanthanide contraction), the ionic radius of actinides monotonically decreases with atomic number (see also Aufbau principle). Physical properties Actinides are typical metals. All of them are soft and have a silvery color (but tarnish in air), relatively high density and plasticity. Some of them can be cut with a knife. Their electrical resistivity varies between 15 and 150 µΩ·cm. The hardness of thorium is similar to that of soft steel, so heated pure thorium can be rolled in sheets and pulled into wire. Thorium is nearly half as dense as uranium and plutonium, but is harder than either of them. All actinides are radioactive, paramagnetic, and, with the exception of actinium, have several crystalline phases: plutonium has seven, and uranium, neptunium and californium three. The crystal structures of protactinium, uranium, neptunium and plutonium do not have clear analogs among the lanthanides and are more similar to those of the 3d-transition metals. All actinides are pyrophoric, especially when finely divided, that is, they spontaneously ignite upon reaction with air at room temperature. The melting point of actinides does not have a clear dependence on the number of f-electrons. The unusually low melting point of neptunium and plutonium (~640 °C) is explained by hybridization of 5f and 6d orbitals and the formation of directional bonds in these metals. Chemical properties Like the lanthanides, all actinides are highly reactive with halogens and chalcogens; however, the actinides react more easily. Actinides, especially those with a small number of 5f-electrons, are prone to hybridization. This is explained by the similarity of the electron energies at the 5f, 7s and 6d shells. Most actinides exhibit a larger variety of valence states, and the most stable are +6 for uranium, +5 for protactinium and neptunium, +4 for thorium and plutonium and +3 for actinium and other actinides. Actinium is chemically similar to lanthanum, which is explained by their similar ionic radii and electronic structures. Like lanthanum, actinium almost always has an oxidation state of +3 in compounds, but it is less reactive and has more pronounced basic properties. Among other trivalent actinides Ac3+ is least acidic, i.e. has the weakest tendency to hydrolyze in aqueous solutions. Thorium is rather active chemically. Owing to lack of electrons on 6d and 5f orbitals, the tetravalent thorium compounds are colorless. At pH < 3, the solutions of thorium salts are dominated by the cations [Th(H2O)8]4+. The Th4+ ion is relatively large, and depending on the coordination number can have a radius between 0.95 and 1.14 Å. As a result, thorium salts have a weak tendency to hydrolyse. The distinctive ability of thorium salts is their high solubility both in water and polar organic solvents. Protactinium exhibits two valence states; the +5 is stable, and the +4 state easily oxidizes to protactinium(V). Thus tetravalent protactinium in solutions is obtained by the action of strong reducing agents in a hydrogen atmosphere. Tetravalent protactinium is chemically similar to uranium(IV) and thorium(IV). Fluorides, phosphates, hypophosphate, iodate and phenylarsonates of protactinium(IV) are insoluble in water and dilute acids. Protactinium forms soluble carbonates. The hydrolytic properties of pentavalent protactinium are close to those of tantalum(V) and niobium(V). The complex chemical behavior of protactinium is a consequence of the start of the filling of the 5f shell in this element. Uranium has a valence from 3 to 6, the last being most stable. In the hexavalent state, uranium is very similar to the group 6 elements. Many compounds of uranium(IV) and uranium(VI) are non-stoichiometric, i.e. have variable composition. For example, the actual chemical formula of uranium dioxide is UO2+x, where x varies between −0.4 and 0.32. Uranium(VI) compounds are weak oxidants. Most of them contain the linear "uranyl" group, . Between 4 and 6 ligands can be accommodated in an equatorial plane perpendicular to the uranyl group. The uranyl group acts as a hard acid and forms stronger complexes with oxygen-donor ligands than with nitrogen-donor ligands. and are also the common form of Np and Pu in the +6 oxidation state. Uranium(IV) compounds exhibit reducing properties, e.g., they are easily oxidized by atmospheric oxygen. Uranium(III) is a very strong reducing agent. Owing to the presence of d-shell, uranium (as well as many other actinides) forms organometallic compounds, such as UIII(C5H5)3 and UIV(C5H5)4. Neptunium has valence states from 3 to 7, which can be simultaneously observed in solutions. The most stable state in solution is +5, but the valence +4 is preferred in solid neptunium compounds. Neptunium metal is very reactive. Ions of neptunium are prone to hydrolysis and formation of coordination compounds. Plutonium also exhibits valence states between 3 and 7 inclusive, and thus is chemically similar to neptunium and uranium. It is highly reactive, and quickly forms an oxide film in air. Plutonium reacts with hydrogen even at temperatures as low as 25–50 °C; it also easily forms halides and intermetallic compounds. Hydrolysis reactions of plutonium ions of different oxidation states are quite diverse. Plutonium(V) can enter polymerization reactions. The largest chemical diversity among actinides is observed in americium, which can have valence between 2 and 6. Divalent americium is obtained only in dry compounds and non-aqueous solutions (acetonitrile). Oxidation states +3, +5 and +6 are typical for aqueous solutions, but also in the solid state. Tetravalent americium forms stable solid compounds (dioxide, fluoride and hydroxide) as well as complexes in aqueous solutions. It was reported that in alkaline solution americium can be oxidized to the heptavalent state, but these data proved erroneous. The most stable valence of americium is 3 in the aqueous solutions and 3 or 4 in solid compounds. Valence 3 is dominant in all subsequent elements up to lawrencium (with the exception of nobelium). Curium can be tetravalent in solids (fluoride, dioxide). Berkelium, along with a valence of +3, also shows the valence of +4, more stable than that of curium; the valence 4 is observed in solid fluoride and dioxide. The stability of Bk4+ in aqueous solution is close to that of Ce4+. Only valence 3 was observed for californium, einsteinium and fermium. The divalent state is proven for mendelevium and nobelium, and in nobelium it is more stable than the trivalent state. Lawrencium shows valence 3 both in solutions and solids. The redox potential \mathit E_\frac{M^4+}{AnO2^2+} increases from −0.32 V in uranium, through 0.34 V (Np) and 1.04 V (Pu) to 1.34 V in americium revealing the increasing reduction ability of the An4+ ion from americium to uranium. All actinides form AnH3 hydrides of black color with salt-like properties. Actinides also produce carbides with the general formula of AnC or AnC2 (U2C3 for uranium) as well as sulfides An2S3 and AnS2. Compounds Oxides and hydroxides An – actinide **Depending on the isotopes Some actinides can exist in several oxide forms such as An2O3, AnO2, An2O5 and AnO3. For all actinides, oxides AnO3 are amphoteric and An2O3, AnO2 and An2O5 are basic, they easily react with water, forming bases: An2O3 + 3 H2O → 2 An(OH)3. These bases are poorly soluble in water and by their activity are close to the hydroxides of rare-earth metals. Np(OH)3 has not yet been synthesized, Pu(OH)3 has a blue color while Am(OH)3 is pink and curium hydroxide Cm(OH)3 is colorless. Bk(OH)3 and Cf(OH)3 are also known, as are tetravalent hydroxides for Np, Pu and Am and pentavalent for Np and Am. The strongest base is of actinium. All compounds of actinium are colorless, except for black actinium sulfide (Ac2S3). Dioxides of tetravalent actinides crystallize in the cubic system, same as in calcium fluoride. Thorium reacting with oxygen exclusively forms the dioxide: Th{} + O2 ->[\ce{1000^\circ C}] \overbrace{ThO2}^{Thorium~dioxide} Thorium dioxide is a refractory material with the highest melting point among any known oxide (3390 °C). Adding 0.8–1% ThO2 to tungsten stabilizes its structure, so the doped filaments have better mechanical stability to vibrations. To dissolve ThO2 in acids, it is heated to 500–600 °C; heating above 600 °C produces a very resistant to acids and other reagents form of ThO2. Small addition of fluoride ions catalyses dissolution of thorium dioxide in acids. Two protactinium oxides have been obtained: PaO2 (black) and Pa2O5 (white); the former is isomorphic with ThO2 and the latter is easier to obtain. Both oxides are basic, and Pa(OH)5 is a weak, poorly soluble base. Decomposition of certain salts of uranium, for example UO2(NO3)·6H2O in air at 400 °C, yields orange or yellow UO3. This oxide is amphoteric and forms several hydroxides, the most stable being uranyl hydroxide UO2(OH)2. Reaction of uranium(VI) oxide with hydrogen results in uranium dioxide, which is similar in its properties with ThO2. This oxide is also basic and corresponds to the uranium hydroxide (U(OH)4). Plutonium, neptunium and americium form two basic oxides: An2O3 and AnO2. Neptunium trioxide is unstable; thus, only Np3O8 could be obtained so far. However, the oxides of plutonium and neptunium with the chemical formula AnO2 and An2O3 are well characterized. Salts *An – actinide **Depending on the isotopes Actinides easily react with halogens forming salts with the formulas MX3 and MX4 (X = halogen). So the first berkelium compound, BkCl3, was synthesized in 1962 with an amount of 3 nanograms. Like the halogens of rare earth elements, actinide chlorides, bromides, and iodides are water-soluble, and fluorides are insoluble. Uranium easily yields a colorless hexafluoride, which sublimates at a temperature of 56.5 °C; because of its volatility, it is used in the separation of uranium isotopes with gas centrifuge or gaseous diffusion. Actinide hexafluorides have properties close to anhydrides. They are very sensitive to moisture and hydrolyze forming AnO2F2. The pentachloride and black hexachloride of uranium were synthesized, but they are both unstable. Action of acids on actinides yields salts, and if the acids are non-oxidizing then the actinide in the salt is in low-valence state: U + 2 H2SO4 → U(SO4)2 + 2 H2 2 Pu + 6 HCl → 2 PuCl3 + 3 H2 However, in these reactions the regenerating hydrogen can react with the metal, forming the corresponding hydride. Uranium reacts with acids and water much more easily than thorium. Actinide salts can also be obtained by dissolving the corresponding hydroxides in acids. Nitrates, chlorides, sulfates and perchlorates of actinides are water-soluble. When crystallizing from aqueous solutions, these salts forming a hydrates, such as Th(NO3)4·6H2O, Th(SO4)2·9H2O and Pu2(SO4)3·7H2O. Salts of high-valence actinides easily hydrolyze. So, colorless sulfate, chloride, perchlorate and nitrate of thorium transform into basic salts with formulas Th(OH)2SO4 and Th(OH)3NO3. The solubility and insolubility of trivalent and tetravalent actinides is like that of lanthanide salts. So phosphates, fluorides, oxalates, iodates and carbonates of actinides are weakly soluble in water; they precipitate as hydrates, such as ThF4·3H2O and Th(CrO4)2·3H2O. Actinides with oxidation state +6, except for the AnO22+-type cations, form [AnO4]2−, [An2O7]2− and other complex anions. For example, uranium, neptunium and plutonium form salts of the Na2UO4 (uranate) and (NH4)2U2O7 (diuranate) types. In comparison with lanthanides, actinides more easily form coordination compounds, and this ability increases with the actinide valence. Trivalent actinides do not form fluoride coordination compounds, whereas tetravalent thorium forms K2ThF6, KThF5, and even K5ThF9 complexes. Thorium also forms the corresponding sulfates (for example Na2SO4·Th(SO4)2·5H2O), nitrates and thiocyanates. Salts with the general formula An2Th(NO3)6·nH2O are of coordination nature, with the coordination number of thorium equal to 12. Even easier is to produce complex salts of pentavalent and hexavalent actinides. The most stable coordination compounds of actinides – tetravalent thorium and uranium – are obtained in reactions with diketones, e.g. acetylacetone. Applications While actinides have some established daily-life applications, such as in smoke detectors (americium) and gas mantles (thorium), they are mostly used in nuclear weapons and as fuel in nuclear reactors. The last two areas exploit the property of actinides to release enormous energy in nuclear reactions, which under certain conditions may become self-sustaining chain reactions. The most important isotope for nuclear power applications is uranium-235. It is used in the thermal reactor, and its concentration in natural uranium does not exceed 0.72%. This isotope strongly absorbs thermal neutrons releasing much energy. One fission act of 1 gram of 235U converts into about 1 MW·day. Of importance, is that emits more neutrons than it absorbs; upon reaching the critical mass, enters into a self-sustaining chain reaction. Typically, uranium nucleus is divided into two fragments with the release of 2–3 neutrons, for example: + ⟶ + + 3 Other promising actinide isotopes for nuclear power are thorium-232 and its product from the thorium fuel cycle, uranium-233. Emission of neutrons during the fission of uranium is important not only for maintaining the nuclear chain reaction, but also for the synthesis of the heavier actinides. Uranium-239 converts via β-decay into plutonium-239, which, like uranium-235, is capable of spontaneous fission. The world's first nuclear reactors were built not for energy, but for producing plutonium-239 for nuclear weapons. About half of the produced thorium is used as the light-emitting material of gas mantles. Thorium is also added into multicomponent alloys of magnesium and zinc. So the Mg-Th alloys are light and strong, but also have high melting point and ductility and thus are widely used in the aviation industry and in the production of missiles. Thorium also has good electron emission properties, with long lifetime and low potential barrier for the emission. The relative content of thorium and uranium isotopes is widely used to estimate the age of various objects, including stars (see radiometric dating). The major application of plutonium has been in nuclear weapons, where the isotope plutonium-239 was a key component due to its ease of fission and availability. Plutonium-based designs allow reducing the critical mass to about a third of that for uranium-235. The "Fat Man"-type plutonium bombs produced during the Manhattan Project used explosive compression of plutonium to obtain significantly higher densities than normal, combined with a central neutron source to begin the reaction and increase efficiency. Thus only 6.2 kg of plutonium was needed for an explosive yield equivalent to 20 kilotons of TNT. (See also Nuclear weapon design.) Hypothetically, as little as 4 kg of plutonium—and maybe even less—could be used to make a single atomic bomb using very sophisticated assembly designs. Plutonium-238 is potentially more efficient isotope for nuclear reactors, since it has smaller critical mass than uranium-235, but it continues to release much thermal energy (0.56 W/g) by decay even when the fission chain reaction is stopped by control rods. Its application is limited by its high price (about US$1000/g). This isotope has been used in thermopiles and water distillation systems of some space satellites and stations. So Galileo and Apollo spacecraft (e.g. Apollo 14) had heaters powered by kilogram quantities of plutonium-238 oxide; this heat is also transformed into electricity with thermopiles. The decay of plutonium-238 produces relatively harmless alpha particles and is not accompanied by gamma-irradiation. Therefore, this isotope (~160 mg) is used as the energy source in heart pacemakers where it lasts about 5 times longer than conventional batteries. Actinium-227 is used as a neutron source. Its high specific energy (14.5 W/g) and the possibility of obtaining significant quantities of thermally stable compounds are attractive for use in long-lasting thermoelectric generators for remote use. 228Ac is used as an indicator of radioactivity in chemical research, as it emits high-energy electrons (2.18 MeV) that can be easily detected. 228Ac-228Ra mixtures are widely used as an intense gamma-source in industry and medicine. Development of self-glowing actinide-doped materials with durable crystalline matrices is a new area of actinide utilization as the addition of alpha-emitting radionuclides to some glasses and crystals may confer luminescence. Toxicity Radioactive substances can harm human health via (i) local skin contamination, (ii) internal exposure due to ingestion of radioactive isotopes, and (iii) external overexposure by β-activity and γ-radiation. Together with radium and transuranium elements, actinium is one of the most dangerous radioactive poisons with high specific α-activity. The most important feature of actinium is its ability to accumulate and remain in the surface layer of skeletons. At the initial stage of poisoning, actinium accumulates in the liver. Another danger of actinium is that it undergoes radioactive decay faster than being excreted. Adsorption from the digestive tract is much smaller (~0.05%) for actinium than radium. Protactinium in the body tends to accumulate in the kidneys and bones. The maximum safe dose of protactinium in the human body is 0.03 µCi that corresponds to 0.5 micrograms of 231Pa. This isotope, which might be present in the air as aerosol, is 2.5 times more toxic than hydrocyanic acid. Plutonium, when entering the body through air, food or blood (e.g. a wound), mostly settles in the lungs, liver and bones with only about 10% going to other organs, and remains there for decades. The long residence time of plutonium in the body is partly explained by its poor solubility in water. Some isotopes of plutonium emit ionizing α-radiation, which damages the surrounding cells. The median lethal dose (LD50) for 30 days in dogs after intravenous injection of plutonium is 0.32 milligram per kg of body mass, and thus the lethal dose for humans is approximately 22 mg for a person weighing 70 kg; the amount for respiratory exposure should be approximately four times greater. Another estimate assumes that plutonium is 50 times less toxic than radium, and thus permissible content of plutonium in the body should be 5 µg or 0.3 µCi. Such amount is nearly invisible under microscope. After trials on animals, this maximum permissible dose was reduced to 0.65 µg or 0.04 µCi. Studies on animals also revealed that the most dangerous plutonium exposure route is through inhalation, after which 5–25% of inhaled substances is retained in the body. Depending on the particle size and solubility of the plutonium compounds, plutonium is localized either in the lungs or in the lymphatic system, or is absorbed in the blood and then transported to the liver and bones. Contamination via food is the least likely way. In this case, only about 0.05% of soluble 0.01% insoluble compounds of plutonium absorbs into blood, and the rest is excreted. Exposure of damaged skin to plutonium would retain nearly 100% of it. Using actinides in nuclear fuel, sealed radioactive sources or advanced materials such as self-glowing crystals has many potential benefits. However, a serious concern is the extremely high radiotoxicity of actinides and their migration in the environment. Use of chemically unstable forms of actinides in MOX and sealed radioactive sources is not appropriate by modern safety standards. There is a challenge to develop stable and durable actinide-bearing materials, which provide safe storage, use and final disposal. A key need is application of actinide solid solutions in durable crystalline host phases.

Arthur Asher Miller (October 17, 1915 – February 10, 2005) was an American playwright, essayist and screenwriter in the 20th-century American theater. Among his most popular plays are All My Sons (1947), Death of a Salesman (1949), The Crucible (1953), and A View from the Bridge (1955). He wrote several screenplays, including The Misfits (1961). The drama Death of a Salesman is considered one of the best American plays of the 20th century. Miller was often in the public eye, particularly during the late 1940s, 1950s and early 1960s. During this time, he received a Pulitzer Prize for Drama, testified before the House Un-American Activities Committee, and married Marilyn Monroe. In 1980, he received the St. Louis Literary Award from the Saint Louis University Library Associates. He received the Praemium Imperiale prize in 2001, the Prince of Asturias Award in 2002, and the Jerusalem Prize in 2003, and the Dorothy and Lillian Gish Prize in 1999. Early life and education Miller was born in Harlem, in the New York City borough of Manhattan, the second of three children of Augusta (Barnett) and Isidore Miller. He was born into a Jewish family of Polish-Jewish descent. His father was born in Radomyśl Wielki, Galicia (then part of Austria-Hungary, now Poland), and his mother was a native of New York whose parents also arrived from that town. Isidore owned a women's clothing manufacturing business employing 400 people. He became a well respected man in the community. The family, including Miller's younger sister Joan Copeland, lived on South 110th Street in Manhattan, owned a summer house in Far Rockaway, Queens, and employed a chauffeur. In the Wall Street Crash of 1929, the family lost almost everything and moved to Gravesend, Brooklyn. (One source says they moved to Midwood.) As a teenager, Miller delivered bread every morning before school to help the family. Miller later published an account of his early years under the title "A Boy Grew in Brooklyn". After graduating in 1932 from Abraham Lincoln High School, he worked at several menial jobs to pay for his college tuition at the University of Michigan. After graduation (), he worked as a psychiatric aide and copywriter before accepting faculty posts at New York University and University of New Hampshire. On May 1, 1935, he joined the League of American Writers (1935–1943), whose members included Alexander Trachtenberg of International Publishers, Franklin Folsom, Louis Untermeyer, I. F. Stone, Myra Page, Millen Brand, Lillian Hellman and Dashiell Hammett. (Members were largely either Communist Party members or fellow travelers.) At the University of Michigan, Miller first majored in journalism and wrote for the student newspaper, The Michigan Daily, and the satirical Gargoyle Humor Magazine. It was during this time that he wrote his first play, No Villain. He switched his major to English, and subsequently won the Avery Hopwood Award for No Villain. The award led him to consider that he could have a career as a playwright. He enrolled in a playwriting seminar with the influential Professor Kenneth Rowe, who emphasized how a play was built to achieve its intended effect, or what Miller called "the dynamics of play construction". Rowe gave Miller realistic feedback and much-needed encouragement, and became a lifelong friend. Miller retained strong ties to his alma mater through the rest of his life, establishing the university's Arthur Miller Award in 1985 and the Arthur Miller Award for Dramatic Writing in 1999, and lending his name to the Arthur Miller Theatre in 2000. In 1937, Miller wrote Honors at Dawn, which also received the Avery Hopwood Award. After his graduation in 1938, he joined the Federal Theatre Project, a New Deal agency established to provide jobs in the theater. He chose the theater project despite the more lucrative offer to work as a scriptwriter for 20th Century Fox. However, Congress, worried about possible Communist infiltration, closed the project in 1939. Miller began working in the Brooklyn Navy Yard while continuing to write radio plays, some of which were broadcast on CBS. Career 1940–1949: Early career In 1940, Miller married Mary Grace Slattery. The couple had two children, Jane (born September 7, 1944) and Robert (May 31, 1947 – March 6, 2022). Miller was exempted from military service during World War II because of a high school football injury to his left kneecap. In 1944 Miller's first play was produced: The Man Who Had All the Luck won the Theatre Guild's National Award. The play closed after four performances with disastrous reviews. In 1947, Miller's play All My Sons, the writing of which had commenced in 1941, was a success on Broadway (earning him his first Tony Award, for Best Author) and his reputation as a playwright was established. Years later, in a 1994 interview with Ron Rifkin, Miller said that most contemporary critics regarded All My Sons as "a very depressing play in a time of great optimism" and that positive reviews from Brooks Atkinson of The New York Times had saved it from failure. In 1948, Miller built a small studio in Roxbury, Connecticut. There, in less than a day, he wrote Act I of Death of a Salesman. Within six weeks, he completed the rest of the play, one of the classics of world theater. Death of a Salesman premiered on Broadway on February 10, 1949, at the Morosco Theatre, directed by Elia Kazan, and starring Lee J. Cobb as Willy Loman, Mildred Dunnock as Linda, Arthur Kennedy as Biff, and Cameron Mitchell as Happy. The play was commercially successful and critically acclaimed, winning a Tony Award for Best Author, the New York Drama Circle Critics' Award, and the Pulitzer Prize for Drama. It was the first play to win all three of these major awards. The play was performed 742 times. In 1949, Miller exchanged letters with Eugene O'Neill regarding Miller's production of All My Sons. O'Neill had sent Miller a congratulatory telegram; in response, he wrote a letter that consisted of a few paragraphs detailing his gratitude for the telegram, apologizing for not responding earlier, and inviting Eugene to the opening of Death of a Salesman. O'Neill replied, accepting the apology, but declining the invitation, explaining that his Parkinson's disease made it difficult to travel. He ended the letter with an invitation to Boston, a trip that never occurred. 1950–1963: Critical years and HUAC controversy In 1955, a one-act version of Miller's verse drama A View from the Bridge opened on Broadway in a joint bill with one of Miller's lesser-known plays, A Memory of Two Mondays. The following year, Miller revised A View from the Bridge as a two-act prose drama, which Peter Brook directed in London. A French-Italian co-production Vu du pont, based on the play, was released in 1962. Shortly before the film's premiere in 1961, Miller and Monroe divorced after five years of marriage. Nineteen months later, on August 5, 1962, Monroe died of a likely drug overdose. Huston, who had also directed her in her first major role in The Asphalt Jungle in 1950, and who had seen her rise to stardom, put the blame for her death on her doctors as opposed to the stresses of being a star: "The girl was an addict of sleeping pills and she was made so by the God-damn doctors. It had nothing to do with the Hollywood set-up." In 1952, Elia Kazan appeared before the House Un-American Activities Committee (HUAC). Kazan named eight members of the Group Theatre, including Clifford Odets, Paula Strasberg, Lillian Hellman, J. Edward Bromberg, and John Garfield, who in recent years had been fellow members of the Communist Party. Miller and Kazan were close friends throughout the late 1940s and early 1950s, but after Kazan's testimony to the HUAC, the pair's friendship ended. After speaking with Kazan about his testimony, Miller traveled to Salem, Massachusetts, to research the witch trials of 1692. He and Kazan did not speak to each other for the next ten years. Kazan later defended his own actions through his film On the Waterfront, in which a dockworker heroically testifies against a corrupt union boss. Miller would retaliate against Kazan's work by writing A View from the Bridge, a play where a longshoreman outs his co-workers motivated only by jealousy and greed. He sent a copy of the initial script to Kazan and when the director asked in jest to direct the movie, Miller replied "I only sent you the script to let you know what I think of Stool-Pigeons." In The Crucible, Miller likened the situation with the House Un-American Activities Committee to the witch hunt in Salem in 1692. The play opened at the Martin Beck Theatre on Broadway on January 22, 1953. Though widely considered only somewhat successful at the time of its release, today The Crucible is Miller's most frequently produced work throughout the world. It was adapted into an opera by Robert Ward in 1961. The HUAC took an interest in Miller himself not long after The Crucible opened, engineering the US State Department's denying him a passport to attend the play's London opening in 1954. When Miller applied in 1956 for a routine renewal of his passport, the House Un-American Activities Committee used this opportunity to subpoena him to appear before the committee. Before appearing, Miller asked the committee not to ask him to name names, to which the chairman, Francis E. Walter (D-PA) agreed. When Miller attended the hearing, to which Monroe accompanied him, risking her own career, he gave the committee a detailed account of his political activities. Reneging on the chairman's promise, the committee demanded the names of friends and colleagues who had participated in similar activities. Miller refused to comply, saying "I could not use the name of another person and bring trouble on him." As a result, a judge found Miller guilty of contempt of Congress in May 1957. Miller was sentenced to a fine and a prison sentence, blacklisted, and disallowed a US passport. In August 1958, his conviction was overturned by the court of appeals, which ruled that Miller had been misled by the chairman of the HUAC. Miller's experience with the HUAC affected him throughout his life. In the late 1970s, he joined other celebrities (including William Styron and Mike Nichols) who were brought together by the journalist Joan Barthel. Barthel's coverage of the highly publicized Barbara Gibbons murder case helped raise bail for Gibbons' son Peter Reilly, who had been convicted of his mother's murder based on what many felt was a coerced confession and little other evidence. Barthel documented the case in her book A Death in Canaan, which was made as a television film of the same name and broadcast in 1978. City Confidential, an A&E Network series, produced an episode about the murder, postulating that part of the reason Miller took such an active interest (including supporting Reilly's defense and using his own celebrity to bring attention to Reilly's plight) was because he had felt similarly persecuted in his run-ins with the HUAC. He sympathized with Reilly, whom he firmly believed to be innocent and to have been railroaded by the Connecticut State Police and the Attorney General who had initially prosecuted the case. Miller began work on writing the screenplay for The Misfits in 1960, directed by John Huston and starring Monroe. It was during the filming that Miller's and Monroe's relationship hit difficulties, and he later said that the filming was one of the lowest points in his life. Monroe was taking drugs to help her sleep and more drugs to help her wake up, which caused her to arrive on the set late and then have trouble remembering her lines. Huston was unaware that Miller and Monroe were having problems in their private life. He recalled later, "I was impertinent enough to say to Arthur that to allow her to take drugs of any kind was criminal and utterly irresponsible. Shortly after that I realized that she wouldn't listen to Arthur at all; he had no say over her actions." 1964–2004: Later career In 1964, After the Fall was produced, and is said to be a deeply personal view of Miller's experiences during his marriage to Monroe. It reunited Miller with his former friend Kazan; they collaborated on the script and direction. It opened on January 23, 1964 at the ANTA Theatre in Washington Square Park amid a flurry of publicity and outrage at putting a Monroe-like character, Maggie, on stage. Robert Brustein, in a review in the New Republic, called After the Fall "a three and one half hour breach of taste, a confessional autobiography of embarrassing explicitness ... There is a misogynistic strain in the play which the author does not seem to recognize. ... He has created a shameless piece of tabloid gossip, an act of exhibitionism which makes us all voyeurs ... a wretched piece of dramatic writing." That year, Miller produced Incident at Vichy. In 1965, he was elected the first American president of PEN International, a position which he held for four years. A year later, he organized the 1966 PEN congress in New York City. He also wrote the penetrating family drama The Price, produced in 1968. It was his most successful play since Death of a Salesman. In 1968, Miller attended the Democratic National Convention as a delegate for Eugene McCarthy. In 1969, Miller's works were banned in the Soviet Union after he campaigned for the freedom of dissident writers. Throughout the 1970s, he spent much of his time experimenting with the theatre, producing one-act plays such as Fame and The Reason Why, and traveling with his wife, producing In the Country and Chinese Encounters with her. Both his 1972 comedy The Creation of the World and Other Business and its musical adaptation, Up from Paradise, were critical and commercial failures. Miller was an unusually articulate commentator on his own work. In 1978, he published a collection of his Theater Essays, edited by Robert A. Martin and with a foreword by Miller. Highlights of the collection included Miller's introduction to his Collected Plays, his reflections on the theory of tragedy, comments on the McCarthy Era, and pieces arguing for a publicly supported theater. Reviewing this collection in the Chicago Tribune, Studs Terkel remarked, "In reading [the Theater Essays] ... you are exhilaratingly aware of a social critic, as well as a playwright, who knows what he's talking about." In 1983, Miller traveled to China to produce and direct Death of a Salesman at the People's Art Theatre in Beijing. It was a success in China and in 1984, Salesman in Beijing, a book about Miller's experiences in Beijing, was published. Around the same time, Death of a Salesman was adapted into a television film starring Dustin Hoffman as Willy Loman. The film was broadcast on CBS, and garnered an audience viewership of 25 million. In late 1987, Miller's autobiographical work, Timebends, was published. Before it was published, it was well known that Miller would not talk about Monroe in interviews; however, in the book, he wrote extensively in detail about his experiences with Monroe. During the early 1990s, Miller wrote three new plays: The Ride Down Mt. Morgan (1991), The Last Yankee (1992), and Broken Glass (1994). In 1996, a film adaptation of The Crucible starring Daniel Day-Lewis, Paul Scofield, Bruce Davison and Winona Ryder was released. Miller spent much of 1996 working on the screenplay. Mr. Peters' Connections was staged Off-Broadway in 1998, and Death of a Salesman was revived on Broadway in 1999 to celebrate its 50th anniversary. The 1999 revival ran for 274 performances at the Eugene O'Neill Theatre, starring Brian Dennehy as Willy Loman. Once again, it was a large critical success, winning a Tony Award for Best Revival of a Play. In 1993, Miller received the National Medal of Arts. He was honored with the PEN/Laura Pels Theater Award for a Master American Dramatist in 1998. In 2001, the National Endowment for the Humanities selected him for the Jefferson Lecture, the U.S. federal government's highest honor for achievement in the humanities. His lecture, "On Politics and the Art of Acting", analyzed political events (including the U.S. presidential election of 2000) in terms of the "arts of performance". It drew attacks from some conservatives such as Jay Nordlinger, who called it "a disgrace"; and George Will, who argued that Miller was not a legitimate "scholar". In October 1999, Miller received The Dorothy and Lillian Gish Prize, given annually to "a man or woman who has made an outstanding contribution to the beauty of the world and to mankind's enjoyment and understanding of life". In 2001, he received the National Book Foundation's Medal for Distinguished Contribution to American Letters. On May 1, 2002, he received Spain's Principe de Asturias Prize for Literature as "the undisputed master of modern drama". Later that year, Ingeborg Morath died of lymphatic cancer at the age of 78. The following year, Miller won the Jerusalem Prize. In December 2004, 89-year-old Miller announced that he had been in love with 34-year-old minimalist painter Agnes Barley and had been living with her at his Connecticut farm since 2002, and that they intended to marry. Miller's final play, Finishing the Picture, opened at the Goodman Theatre, Chicago, in the fall of 2004, with one character said to be based on Barley. It was reportedly based on his experience during the filming of The Misfits, though Miller insisted the play was a work of fiction with independent characters that were no more than composite shadows of history. Personal life Marriages and family In June 1956, Miller left his first wife, Mary Slattery, whom he had married in 1940, and wed film star Marilyn Monroe. They met in 1951, had a brief affair, and remained in contact. Monroe had just turned 30 when they married; she never had a real family of her own and was eager to join the family of her new husband. Monroe began to reconsider her career and the fact that trying to manage it made her feel helpless. She admitted to Miller, "I hate Hollywood. I don't want it any more. I want to live quietly in the country and just be there when you need me. I can't fight for myself any more." Monroe converted to Judaism to "express her loyalty and get close to both Miller and his parents", writes biographer Jeffrey Meyers. She told her close friend, Susan Strasberg: "I can identify with the Jews. Everybody's always out to get them, no matter what they do, like me." Soon after Monroe converted, Egypt banned all of her movies. Away from Hollywood and the culture of celebrity, Monroe's life became more normal; she began cooking, keeping house and giving Miller more attention and affection than he had been used to. Later that year, Miller was subpoenaed by the House Un-American Activities Committee, and Monroe accompanied him. In her personal notes, she wrote about her worries during this period: Monroe obtained a "Mexican divorce" from Miller in January 1961. In February 1962, Miller married photographer Inge Morath, who had worked as a photographer documenting the production of The Misfits. The first of their two children, Rebecca, was born September 15, 1962. Their son Daniel was born with Down syndrome in November 1966. Against his wife's wishes, Miller had him institutionalized, first at a home for infants in New York City, then at the Southbury Training School in Connecticut. Though Morath visited Daniel often, Miller never visited him at the school and rarely spoke of him. Miller and Inge remained together until her death in 2002. Miller's son-in-law, actor Daniel Day-Lewis, is said to have visited Daniel frequently, and to have persuaded Miller to meet with him. Death Miller died on the evening of February 10, 2005 (coincidentally the 56th anniversary of the Broadway debut of Death of a Salesman) at age 89 of bladder cancer and heart failure, at his home in Roxbury, Connecticut. He had been in hospice care at his sister's apartment in New York since his release from hospital the previous month. He was surrounded by Barley, family and friends. His body was interred at Roxbury Center Cemetery in Roxbury. Within hours of her father's death, Rebecca Miller, who had been consistently opposed to the relationship with Agnes Barley, ordered her to vacate the home she shared with Arthur. Legacy Miller's writing career spanned over seven decades, and at the time of his death, he was considered one of the 20th century's greatest dramatists. After his death, many respected actors, directors, and producers paid tribute to him, some calling him the last great practitioner of the American stage, and Broadway theatres darkened their lights in a show of respect. Miller's alma mater, the University of Michigan, opened the Arthur Miller Theatre in March 2007. Per his express wish, it is the only theater in the world that bears his name. Miller's letters, notes, drafts and other papers are housed at the Harry Ransom Humanities Research Center at the University of Texas at Austin. Miller is also a member of the American Theater Hall of Fame. He was inducted in 1979. In 1993, he received the Four Freedoms Award for Freedom of Speech. In 2017, his daughter, Rebecca Miller, a writer and filmmaker, completed a documentary about her father's life, Arthur Miller: Writer. Minor planet 3769 Arthurmiller is named after him. In the 2022 Netflix film Blonde, Miller was portrayed by Adrien Brody. Foundation The Arthur Miller Foundation was founded to honor the legacy of Miller and his New York City Public School education. Its mission is "Promoting increased access and equity to theater arts education in our schools and increasing the number of students receiving theater arts education as an integral part of their academic curriculum." Its other initiatives include certification of new theater teachers and their placement in public schools, increasing the number of theater teachers in the system from the current estimate of 180 teachers in 1800 schools, supporting professional development of all certified theater teachers, and providing teaching artists, cultural partners, physical spaces, and theater ticket allocations for students. The foundation's primary purpose is to provide arts education in the New York City school system. Its current chancellor is Carmen Farina, a prominent proponent of the Common Core State Standards Initiative. The Master Arts Council includes Alec Baldwin, Ellen Barkin, Bradley Cooper, Dustin Hoffman, Scarlett Johansson, Tony Kushner, Julianne Moore, Michael Moore, Liam Neeson, David O. Russell, and Liev Schreiber. Miller's son-in-law, Daniel Day-Lewis, has served on the current board of directors since 2016. The foundation celebrated Miller's 100th birthday with a one-night performance of his seminal works in November 2015. The Arthur Miller Foundation currently supports a pilot program in theater and film at the public school Quest to Learn, in partnership with the Institute of Play. The model is being used as an in-school elective theater class and lab. Its objective is to create a sustainable theater education model to disseminate to teachers at professional development workshops. Archive Miller donated thirteen boxes of his earliest manuscripts to the Harry Ransom Center at the University of Texas at Austin in 1961 and 1962. This collection included the original handwritten notebooks and early typed drafts for Death of a Salesman, The Crucible, All My Sons, and other works. In January, 2018, the Ransom Center announced the acquisition of the remainder of the Miller archive, totaling over 200 boxes. The full archive opened in November, 2019. Literary and public criticism Christopher Bigsby wrote Arthur Miller: The Definitive Biography based on boxes of papers Miller made available to him before his death in 2005. The book was published in November 2008, and is reported to reveal unpublished works in which Miller "bitterly attack[ed] the injustices of American racism long before it was taken up by the civil rights movement". In his book Trinity of Passion, author Alan M. Wald conjectures that Miller was "a member of a writer's unit of the Communist Party around 1946," using the pseudonym Matt Wayne, and editing a drama column in the magazine The New Masses. In 1999 the writer Christopher Hitchens attacked Miller for comparing the Monica Lewinsky investigation to the Salem witch hunt. Miller had asserted a parallel between the examination of physical evidence on Lewinsky's dress and the examinations of women's bodies for signs of the "Devil's Marks" in Salem. Hitchens scathingly disputed the parallel. In his memoir, Hitch-22, Hitchens bitterly noted that Miller, despite his prominence as a left-wing intellectual, had failed to support author Salman Rushdie during the Iranian fatwa involving The Satanic Verses.

An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is usually embedded in a container format or an audio data format with defined storage layer. Format types It is important to distinguish between the audio coding format, the container containing the raw audio data, and an audio codec. A codec performs the encoding and decoding of the raw audio data while this encoded data is (usually) stored in a container file. Although most audio file formats support only one type of audio coding data (created with an audio coder), a multimedia container format (as Matroska or AVI) may support multiple types of audio and video data. There are three major groups of audio file formats: Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM; Formats with lossless compression, such as FLAC, Monkey's Audio (filename extension .ape), WavPack (filename extension .wv), TTA, ATRAC Advanced Lossless, ALAC (filename extension .m4a), MPEG-4 SLS, MPEG-4 ALS, MPEG-4 DST, Windows Media Audio Lossless (WMA Lossless), and Shorten (SHN). Formats with lossy compression, such as Opus, MP3, Vorbis, Musepack, AAC, ATRAC and Windows Media Audio Lossy (WMA lossy). Uncompressed audio format One major uncompressed audio format, LPCM, is the same variety of PCM as used in Compact Disc Digital Audio and is the format most commonly accepted by low level audio APIs and D/A converter hardware. Although LPCM can be stored on a computer as a raw audio format, it is usually stored in a .wav file on Windows or in a .aiff file on macOS. The Audio Interchange File Format (AIFF) format is based on the Interchange File Format (IFF), and the WAV format is based on the similar Resource Interchange File Format (RIFF). WAV and AIFF are designed to store a wide variety of audio formats, lossless and lossy; they just add a small, metadata-containing header before the audio data to declare the format of the audio data, such as LPCM with a particular sample rate, bit depth, endianness and number of channels. Since WAV and AIFF are widely supported and can store LPCM, they are suitable file formats for storing and archiving an original recording. BWF (Broadcast Wave Format) is a standard audio format created by the European Broadcasting Union as a successor to WAV. Among other enhancements, BWF allows more robust metadata to be stored in the file. See European Broadcasting Union: Specification of the Broadcast Wave Format (EBU Technical document 3285, July 1997). This is the primary recording format used in many professional audio workstations in the television and film industry. BWF files include a standardized timestamp reference which allows for easy synchronization with a separate picture element. Stand-alone, file based, multi-track recorders from AETA, Sound Devices, Zaxcom, HHB Communications Ltd, Fostex, Nagra, Aaton, and TASCAM all use BWF as their preferred format. Lossless compressed audio format A lossless compressed audio format stores data in less space without losing any information. The original, uncompressed data can be recreated from the compressed version. Uncompressed audio formats encode both sound and silence with the same number of bits per unit of time. Encoding an uncompressed minute of absolute silence produces a file of the same size as encoding an uncompressed minute of music. In a lossless compressed format, however, the music would occupy a smaller file than an uncompressed format and the silence would take up almost no space at all. Lossless compression formats include FLAC, WavPack, Monkey's Audio, ALAC (Apple Lossless). They provide a compression ratio of about 2:1 (i.e. their files take up half the space of PCM). Development in lossless compression formats aims to reduce processing time while maintaining a good compression ratio. Lossy compressed audio format Lossy audio format enables even greater reductions in file size by removing some of the audio information and simplifying the data. This, of course, results in a reduction in audio quality, but a variety of techniques are used, mainly by exploiting psychoacoustics, to remove the parts of the sound that have the least effect on perceived quality, and to minimize the amount of audible noise added during the process. The popular MP3 format is probably the best-known example, but the AAC format found on the iTunes Music Store is also common. Most formats offer a range of degrees of compression, generally measured in bit rate. The lower the rate, the smaller the file and the more significant the quality loss.

Area 51 is the common name of a highly classified United States Air Force (USAF) facility within the Nevada Test and Training Range. A remote detachment administered by Edwards Air Force Base, the facility is officially called Homey Airport or Groom Lake (after the salt flat next to its airfield). Details of its operations are not made public, but the USAF says that it is an open training range, and it is commonly thought to support the development and testing of experimental aircraft and weapons systems. The USAF and CIA acquired the site in 1955, primarily for flight testing the Lockheed U-2 aircraft. The intense secrecy surrounding the base has made it the frequent subject of conspiracy theories and a central component of unidentified flying object (UFO) folklore. It has never been declared a secret base, but all research and occurrences in Area 51 are Top Secret/Sensitive Compartmented Information (TS/SCI). The CIA publicly acknowledged the base's existence on 25 June 2013, following a Freedom of Information Act (FOIA) request filed in 2005 and declassified documents detailing its history and purpose. Area 51 is located in the southern portion of Nevada, north-northwest of Las Vegas. The surrounding area is a popular tourist destination, including the small town of Rachel on the "Extraterrestrial Highway". Geography Area 51 The original rectangular base of is now part of the so-called "Groom box", a rectangular area, measuring , of restricted airspace. The area is connected to the internal Nevada Test Site (NTS) road network, with paved roads leading south to Mercury and west to Yucca Flat. Leading northeast from the lake, the wide and well-maintained Groom Lake Road runs through a pass in the Jumbled Hills. The road formerly led to mines in the Groom basin but has been improved since their closure. Its winding course runs past a security checkpoint, but the restricted area around the base extends farther east. After leaving the restricted area, Groom Lake Road descends eastward to the floor of the Tikaboo Valley, passing the dirt-road entrances to several small ranches, before converging with State Route 375, the "Extraterrestrial Highway", south of Rachel. Area 51 shares a border with the Yucca Flat region of the Nevada Test Site, the location of 739 of the 928 nuclear tests conducted by the United States Department of Energy at NTS. The Yucca Mountain nuclear waste repository is southwest of Groom Lake. Groom Lake Groom Lake is a salt flat in Nevada used for runways of the Nellis Bombing Range Test Site airport (XTA/KXTA) on the north of the Area 51 USAF military installation. The lake at elevation is approximately from north to south and from east to west at its widest point. Located within the namesake Groom Lake Valley portion of the Tonopah Basin, the lake is south of Rachel, Nevada. History The origin of the name "Area 51" is unclear. It is believed to be from an Atomic Energy Commission (AEC) numbering grid, although Area 51 is not part of this system; it is adjacent to Area 15. Another explanation is that 51 was used because it was unlikely that the AEC would use the number. According to the Central Intelligence Agency (CIA), the correct names for the facility are Homey Airport (XTA/KXTA) and Groom Lake, though the name "Area 51" was used in a CIA document from the Vietnam War. The facility has also been referred to as "Dreamland" and "Paradise Ranch", among other nicknames, with the former also being the approach control call sign for the surrounding area. The USAF public relations has referred to the facility as "an operating location near Groom Dry Lake". The special use airspace around the field is referred to as Restricted Area 4808 North (R-4808N). Lead and silver were discovered in the southern part of the Groom Range in 1864, and the English company Groome Lead Mines Limited financed the Conception Mines in the 1870s, giving the district its name (nearby mines included Maria, Willow, and White Lake). J. B. Osborne and partners acquired the controlling interest in Groom in 1876, and Osbourne's son acquired it in the 1890s. Mining continued until 1918, then resumed after World War II until the early 1950s. The airfield on the Groom Lake site began service in 1942 as Indian Springs Air Force Auxiliary Field and consisted of two unpaved 5,000-foot (1,524 m) runways. U-2 program The Central Intelligence Agency (CIA) established the Groom Lake test facility in April 1955 for Project AQUATONE: the development of the Lockheed U-2 strategic reconnaissance aircraft. Project director Richard M. Bissell Jr. understood that the flight test and pilot training programs could not be conducted at Edwards Air Force Base or Lockheed's Palmdale facility, given the extreme secrecy surrounding the project. He conducted a search for a suitable testing site for the U-2 under the same extreme security as the rest of the project. He notified Lockheed, who sent an inspection team out to Groom Lake. According to Lockheed's U-2 designer Kelly Johnson: The lake bed made an ideal strip for testing aircraft, and the Emigrant Valley's mountain ranges and the NTS perimeter protected the site from visitors; it was about north of Las Vegas. The CIA asked the AEC to acquire the land, designated "Area 51" on the map, and to add it to the Nevada Test Site. Johnson named the area "Paradise Ranch" to encourage workers to move to "the new facility in the middle of nowhere", as the CIA later described it, and the name became shortened to "the Ranch". On 4May 1955, a survey team arrived at Groom Lake and laid out a north–south runway on the southwest corner of the lakebed and designated a site for a base support facility. The Ranch initially consisted of little more than a few shelters, workshops, and trailer homes in which to house its small team. A little over three months later, the base consisted of a single paved runway, three hangars, a control tower, and rudimentary accommodations for test personnel. The base's few amenities included a movie theater and volleyball court. There was also a mess hall, several wells, and fuel storage tanks. CIA, Air Force, and Lockheed personnel began arriving by July 1955. The Ranch received its first U-2 delivery on 24 July 1955 from Burbank on a C-124 Globemaster II cargo plane, accompanied by Lockheed technicians on a Douglas DC-3. Regular Military Air Transport Service flights were set up between Area 51 and Lockheed's offices in Burbank, California. To preserve secrecy, personnel flew to Nevada on Monday mornings and returned to California on Friday evenings. OXCART program Project OXCART was established in August 1959 for "antiradar studies, aerodynamic structural tests, and engineering designs" and all later work on the Lockheed A-12. This included testing at Groom Lake, which had inadequate facilities consisting of buildings for only 150 people, a asphalt runway, and limited fuel, hangar, and shop space. Groom Lake had received the name "Area 51" when A-12 test facility construction began in September 1960, including a new runway to replace the existing runway. Reynolds Electrical and Engineering Company (REECo) began construction of "Project 51" on 1October 1960 with double-shift construction schedules. The contractor upgraded base facilities and built a new runway (14/32) diagonally across the southwest corner of the lakebed. They marked an Archimedean spiral on the dry lake approximately two miles across so that an A-12 pilot approaching the end of the overrun could abort instead of plunging into the sagebrush. Area 51 pilots called it "The Hook". For crosswind landings, they marked two unpaved airstrips (runways 9/27 and 03/21) on the dry lakebed. By August 1961, construction of the essential facilities was complete; three surplus Navy hangars were erected on the base's north side while hangar7 was new construction. The original U-2 hangars were converted to maintenance and machine shops. Facilities in the main cantonment area included workshops and buildings for storage and administration, a commissary, a control tower, a fire station, and housing. The Navy also contributed more than 130 surplus Babbitt duplex housing units for long-term occupancy facilities. Older buildings were repaired, and additional facilities were constructed as necessary. A reservoir pond surrounded by trees served as a recreational area one mile north of the base. Other recreational facilities included a gymnasium, a movie theater, and a baseball diamond. A permanent aircraft fuel tank farm was constructed by early 1962 for the special JP-7 fuel required by the A-12. Seven tanks were constructed, with a total capacity of 1,320,000 gallons. Security was enhanced for the arrival of OXCART and the small mine was closed in the Groom basin. In January 1962, the Federal Aviation Administration (FAA) expanded the restricted airspace in the vicinity of Groom Lake, and the lakebed became the center of a 600-square mile addition to restricted area R-4808N. The CIA facility received eight USAF F-101 Voodoos for training, two T-33 Shooting Star trainers for proficiency flying, a C-130 Hercules for cargo transport, a U-3A for administrative purposes, a helicopter for search and rescue, and a Cessna 180 for liaison use, and Lockheed provided an F-104 Starfighter for use as a chase plane. The first A-12 test aircraft was covertly trucked from Burbank on 26 February 1962 and arrived at Groom Lake on 28 February. It made its first flight 26 April 1962 when the base had over 1,000 personnel. The closed airspace above Groom Lake was within the Nellis Air Force Range airspace, and pilots saw the A-12 20 to 30 times. Groom was also the site of the first Lockheed D-21 drone test flight on 22 December 1964. By the end of 1963, nine A-12s were at Area 51, assigned to the CIA-operated "1129th Special Activities Squadron". D-21 Tagboard Following the loss of Gary Powers' U-2 over the Soviet Union, there were several discussions about using the A-12 OXCART as an unpiloted drone aircraft. Although Kelly Johnson had come to support the idea of drone reconnaissance, he opposed the development of an A-12 drone, contending that the aircraft was too large and complex for such a conversion. However, the Air Force agreed to fund the study of a high-speed, high-altitude drone aircraft in October 1962. The Air Force interest seems to have moved the CIA to take action, the project designated "Q-12". By October 1963, the drone's design had been finalized. At the same time, the Q-12 underwent a name change. To separate it from the other A-12-based projects, it was renamed the "D-21". (The "12" was reversed to "21"). "Tagboard" was the project's code name. The first D-21 was completed in the spring of 1964 by Lockheed. After four more months of checkouts and static tests, the aircraft was shipped to Groom Lake and reassembled. It was to be carried by a two-seat derivative of the A-12, designated the "M-21". When the D-21/M-21 reached the launch point, the first step would be to blow off the D-21's inlet and exhaust covers. With the D-21/M-21 at the correct speed and altitude, the LCO would start the ramjet and the other systems of the D-21. "With the D-21's systems activated and running, and the launch aircraft at the correct point, the M-21 would begin a slight pushover, the LCO would push a final button, and the D-21 would come off the pylon". Difficulties were addressed throughout 1964 and 1965 at Groom Lake with various technical issues. Captive flights showed unforeseen aerodynamic difficulties. By late January 1966, more than a year after the first captive flight, everything seemed ready. The first D-21 launch was made on 5March 1966 with a successful flight, with the D-21 flying 120 miles with limited fuel. A second D-21 flight was successful in April 1966 with the drone flying 1,200 miles, reaching Mach 3.3 and 90,000 feet. An accident on 30 July 1966 with a fully fueled D-21, on a planned checkout flight, suffered from an unstart of the drone after its separation, causing it to collide with the M-21 launch aircraft. The two crewmen ejected and landed in the ocean 150 miles offshore. One crew member was picked up by a helicopter, but the other, having survived the aircraft breakup and ejection, drowned when sea water entered his pressure suit. Kelly Johnson personally cancelled the entire program, having had serious doubts about its feasibility from the start. A number of D-21s had already been produced, and rather than scrapping the whole effort, Johnson again proposed to the Air Force that they be launched from a B-52H bomber. By late summer of 1967, the modification work to both the D-21 (now designated D-21B) and the B-52Hs was complete. The test program could now resume. The test missions were flown out of Groom Lake, with the actual launches over the Pacific. The first D-21B to be flown was Article 501, the prototype. The first attempt was made on 28 September 1967 and ended in complete failure. As the B-52 was flying toward the launch point, the D-21B fell off the pylon. The B-52H gave a sharp lurch as the drone fell free. The booster fired and was "quite a sight from the ground". The failure was traced to a stripped nut on the forward right attachment point on the pylon. Several more tests were made, none of which met with success. However, the fact is that the resumptions of D-21 tests took place against a changing reconnaissance background. The A-12 had finally been allowed to deploy, and the SR-71 was soon to replace it. At the same time, new developments in reconnaissance satellite technology were nearing operation. Up to this point, the limited number of satellites available restricted coverage to the Soviet Union. A new generation of reconnaissance satellites could soon cover targets anywhere in the world. The satellites' resolution would be comparable to that of aircraft but without the slightest political risk. Time was running out for the Tagboard. Several more test flights, including two over China, were made from Beale AFB, California, in 1969 and 1970, to varying degrees of success. On 15 July 1971, Kelly Johnson received a wire canceling the D-21B program. The remaining drones were transferred by a C-5A and placed in dead storage. The tooling used to build the D-21Bs was ordered destroyed. Like the A-12 Oxcart, the D-21B Tagboard drones remained a Black airplane, even in retirement. Their existence was not suspected until August 1976, when the first group was placed in storage at the Davis-Monthan AFB Military Storage and Disposition Center. A second group arrived in 1977. They were labeled "GTD-21Bs" (GT stood for ground training). Davis-Monthan is an open base, with public tours of the storage area at the time, so the odd-looking drones were soon spotted and photos began appearing in magazines. Speculation about the D-21Bs circulated within aviation circles for years, and it was not until 1982 that details of the Tagboard program were released. However, it was not until 1993 that the B-52/D-21B program was made public. That same year, the surviving D-21Bs were released to museums. Foreign technology evaluation During the Cold War, one of the missions carried out by the United States was the test and evaluation of captured Soviet fighter aircraft. Beginning in the late 1960s, and for several decades, Area 51 played host to an assortment of Soviet-built aircraft. Munir Redfas defection with a Mikoyan-Gurevich MiG-21 from Iraq for Israel's Mossad in Operation Diamond led to the HAVE DOUGHNUT, HAVE DRILL and HAVE FERRY programs. The first MiGs flown in the United States were used to evaluate the aircraft in performance, technical, and operational capabilities, pitting the types against U.S. fighters. This was not a new mission, as testing of foreign technology by the USAF began during World War II. After the war, testing of acquired foreign technology was performed by the Air Technical Intelligence Center (ATIC, which became very influential during the Korean War), under the direct command of the Air Materiel Control Department. In 1961, ATIC became the Foreign Technology Division (FTD) and was reassigned to Air Force Systems Command. ATIC personnel were sent anywhere where foreign aircraft could be found. The focus of Air Force Systems Command limited the use of the fighter as a tool with which to train the front line tactical fighter pilots. Air Force Systems Command recruited its pilots from the Air Force Flight Test Center at Edwards Air Force Base, California, who were usually graduates from various test pilot schools. Tactical Air Command selected its pilots primarily from the ranks of the Weapons School graduates. In August 1966, Iraqi Air Force fighter pilot Captain Munir Redfa defected, flying his MiG-21 to Israel after being ordered to attack Iraqi Kurd villages with napalm. His aircraft was transferred to Groom Lake in late 1967 for study. Israel loaned the MiG-21 to the US Air Force from January 1968 to April 1968. In 1968, the US Air Force and Navy jointly formed a project known as HAVE DOUGHNUT in which Air Force Systems Command, Tactical Air Command, and the U.S. Navy's Air Test and Evaluation Squadron Four (VX-4) flew this acquired Soviet made aircraft in simulated air combat training. As U.S. possession of the Soviet MiG-21 was, itself, secret, it was tested at Groom Lake. A joint Air Force-Navy team was assembled for a series of dogfight tests. Comparisons between the F-4 and the MiG-21 indicated that, on the surface, they were evenly matched. The HAVE DOUGHNUT tests showed the skill of the man in the cockpit was what made the difference. When the Navy or Air Force pilots flew the MiG-21, the results were a draw; the F-4 would win some fights, the MiG-21 would win others. There were no clear advantages. The problem was not with the planes, but with the pilots flying them. The pilots would not fly either plane to its limits. One of the Navy pilots was Marland W. "Doc" Townsend, then commander of VF-121, the F-4 training squadron at NAS Miramar. He was an engineer and a Korean War veteran and had flown almost every navy aircraft. When he flew against the MiG-21, he would outmaneuver it every time. The Air Force pilots would not go vertical in the MiG-21. The HAVE DOUGHNUT project officer was Tom Cassidy, a pilot with VX-4, the Navy's Air Development Squadron at Point Mugu. He had been watching as Townsend "waxed" the Air Force MiG-21 pilots. Cassidy climbed into the MiG-21 and went up against Townsend's F-4. This time the result was far different. Cassidy was willing to fight in the vertical, flying the plane to the point where it was buffeting, just above the stall. Cassidy was able to get on the F-4's tail. After the flight, they realized the MiG-21 turned better than the F-4 at lower speeds. The key was for the F-4 to keep its speed up. An F-4 had defeated the MiG-21; the weakness of the Soviet plane had been found. Further test flights confirmed what was learned. It was also clear that the MiG-21 was a formidable enemy. United States pilots would have to fly much better than they had been to beat it. This would require a special school to teach advanced air combat techniques. On 12 August 1968, two Syrian air force lieutenants, Walid Adham and Radfan Rifai, took off in a pair of MiG-17Fs on a training mission. They lost their way and, believing they were over Lebanon, landed at the Betzet Landing Field in northern Israel. (One version has it that they were led astray by an Arabic-speaking Israeli). Prior to the end of 1968 these MiG-17s were transferred from Israeli stocks and added to the Area 51 test fleet. The aircraft were given USAF designations and fake serial numbers so that they could be identified in DOD standard flight logs. As in the earlier program, a small group of Air Force and Navy pilots conducted mock dogfights with the MiG-17s. Selected instructors from the Navy's Top Gun school at NAS Miramar, California, were chosen to fly against the MiGs for familiarization purposes. Very soon, the MiG-17's shortcomings became clear. It had an extremely simple, even crude, control system that lacked the power-boosted controls of American aircraft. The F-4's twin engines were so powerful it could accelerate out of range of the MiG-17's guns in thirty seconds. It was important for the F-4 to keep its distance from the MiG-17. As long as the F-4 was one and a half miles from the MiG-17, it was outside the reach of the Soviet fighter's guns, but the MiG was within reach of the F-4's missiles. The data from the HAVE DOUGHNUT and HAVE DRILL tests were provided to the newly formed Top Gun school at NAS Miramar. By 1970, the HAVE DRILL program was expanded; a few selected fleet F-4 crews were given the chance to fight the MiGs. The most important result of Project HAVE DRILL is that no Navy pilot who flew in the project defeated the MiG-17 Fresco in the first engagement. The HAVE DRILL dogfights were by invitation only. The other pilots based at Nellis Air Force Base were not to know about the U.S.-operated MiGs. To prevent any sightings, the airspace above the Groom Lake range was closed. On aeronautical maps, the exercise area was marked in red ink. The forbidden zone became known as "Red Square". During the remainder of the Vietnam War, the Navy kill ratio climbed to 8.33 to 1. In contrast, the Air Force rate improved only slightly to 2.83 to 1. The reason for this difference was Top Gun. The Navy had revitalized its air combat training, while the Air Force had stayed stagnant. Most of the Navy MiG kills were by Top Gun graduates. In May 1973, Project HAVE IDEA was formed, which took over from the older HAVE DOUGHNUT, HAVE FERRY and HAVE DRILL projects, and the project was transferred to the Tonopah Test Range Airport. At Tonopah, testing of foreign technology aircraft continued and expanded throughout the 1970s and 1980s. Area 51 also hosted another foreign materiel evaluation program called HAVE GLIB. This involved testing Soviet tracking and missile control radar systems. A complex of actual and replica Soviet-type threat systems began to grow around "Slater Lake", a mile northwest of the main base, along with an acquired Soviet "Barlock" search radar placed at Tonopah Air Force Station. They were arranged to simulate a Soviet-style air defense complex. The Air Force began funding improvements to Area 51 in 1977 under project SCORE EVENT. In 1979, the CIA transferred jurisdiction of the Area 51 site to the Air Force Flight Test Center at Edwards AFB, California. Sam Mitchell, the last CIA commander of Area 51, relinquished command to USAF Lt. Col. Larry D. McClain. In 2017, a USAF aircraft crashed at the site, killing the pilot, Colonel Eric "Doc" Schultz. The USAF refused to release further information regarding the crash. In 2022, unconfirmed reports emerged that the crash involved an SU-27 that was part of the classified Foreign Materials Exploitation program. The reports claimed that the aircraft suffered a technical issue that resulted in both crew members ejecting from the aircraft, resulting in the death of Schultz. Have Blue/F-117 program The Lockheed Have Blue prototype stealth fighter (a smaller proof-of-concept model of the F-117 Nighthawk) first flew at Groom in December 1977. In 1978, the Air Force awarded a full-scale development contract for the F-117 to Lockheed Corporation's Advanced Development Projects. On 17 January 1981 the Lockheed test team at Area 51 accepted delivery of the first full-scale development (FSD) prototype 79–780, designated YF-117A. At 6:05 am on 18 June 1981 Lockheed Skunk Works test pilot Hal Farley lifted the nose of YF-117A 79–780 off the runway of Area 51. Meanwhile, Tactical Air Command (TAC) decided to set up a group-level organization to guide the F-117A to an initial operating capability. That organization became the 4450th Tactical Group (Initially designated "A Unit"), which officially activated on 15 October 1979 at Nellis AFB, Nevada, although the group was physically located at Area 51. The 4450th TG also operated the A-7D Corsair II as a surrogate trainer for the F-117A, and these operations continued until 15 October 1982 under the guise of an avionics test mission. Flying squadrons of the 4450th TG were the 4450th Tactical Squadron (Initially designated "I Unit") activated on 11 June 1981, and 4451st Tactical Squadron (Initially designated "P Unit") on 15 January 1983. The 4450th TS, stationed at Area 51, was the first F-117A squadron, while the 4451st TS was stationed at Nellis AFB and was equipped with A-7D Corsair IIs painted in a dark motif, tail coded "LV". Lockheed test pilots put the YF-117 through its early paces. A-7Ds were used for pilot training before any F-117As had been delivered by Lockheed to Area 51, later the A-7D's were used for F-117A chase testing and other weapon tests at the Nellis Range. On 15 October 1982, Major Alton C. Whitley Jr. became the first USAF 4450th TG pilot to fly the F-117A. Although ideal for testing, Area 51 was not a suitable location for an operational group, so a new covert base had to be established for F-117 operations. Tonopah Test Range Airport was selected for operations of the first USAF F-117 unit, the 4450th Tactical Group (TG). From October 1979, the Tonopah Airport base was reconstructed and expanded. The 6,000-foot runway was lengthened to 10,000 feet. Taxiways, a concrete apron, a large maintenance hangar, and a propane storage tank were added. By early 1982, four more YF-117As were operating at the base. After finding a large scorpion in their offices, the testing team (Designated "R Unit") adopted it as their mascot and dubbed themselves the "Baja Scorpions". Testing of a series of ultra-secret prototypes continued at Area 51 until mid-1981 when testing transitioned to the initial production of F-117 stealth fighters. The F-117s were moved to and from Area 51 by C-5 during darkness to maintain security. The aircraft were defueled, disassembled, cradled, and then loaded aboard the C-5 at night, flown to Lockheed, and unloaded at night before reassembly and flight testing. Groom performed radar profiling, F-117 weapons testing, and training of the first group of frontline USAF F-117 pilots. While the "Baja Scorpions" were working on the F-117, there was also another group at work in secrecy, known as "the Whalers" working on Tacit Blue. A fly-by-wire technology demonstration aircraft with curved surfaces and composite material, to evade radar, was a prototype, and never went into production. Nevertheless, this strange-looking aircraft was responsible for many of the stealth technology advances that were used on several other aircraft designs, and had a direct influence on the B-2; with the first flight of Tacit Blue being performed on 5February 1982, by Northrop Grumman test pilot, Richard G. Thomas. Production FSD airframes from Lockheed were shipped to Area 51 for acceptance testing. As the Baja Scorpions tested the aircraft with functional check flights and L.O. verification, the operational airplanes were then transferred to the 4450th TG. On 17 May 1982, the move of the 4450th TG from Groom Lake to Tonopah was initiated, with the final components of the move completed in early 1983. Production FSD airframes from Lockheed were shipped to Area 51 for acceptance testing. As the Baja Scorpions tested the aircraft with functional check flights and L.O. verification, the operational airplanes were then transferred to the 4450th TG at Tonopah. The R-Unit was inactivated on 30 May 1989. Upon inactivation, the unit was reformed as Detachment 1, 57th Fighter Weapons Wing (FWW). In 1990, the last F-117A (843) was delivered from Lockheed. After completion of acceptance flights at Area 51 of this last new F-117A aircraft, the flight test squadron continued flight test duties of refurbished aircraft after modifications by Lockheed. In February/March 1992 the test unit moved from Area 51 to the USAF Palmdale Plant 42 and was integrated with the Air Force Systems Command 6510th Test Squadron. Some testing, especially RCS verification and other classified activity was still conducted at Area 51 throughout the operational lifetime of the F-117. The recently inactivated (2008) 410th Flight Test Squadron traces its roots, if not its formal lineage to the 4450th TG R-unit. Later operations Since the F-117 became operational in 1983, operations at Groom Lake have continued. The base and its associated runway system were expanded, including the expansion of housing and support facilities. In 1995, the federal government expanded the exclusionary area around the base to include nearby mountains that had hitherto afforded the only decent overlook of the base, prohibiting access to of land formerly administered by the Bureau of Land Management. On 22 October 2015, a federal judge signed an order giving land that belonged to a Nevada family since the 1870s to the United States Air Force for expanding Area 51. According to the judge, the land that overlooked the base was taken to address security and safety concerns connected with their training and testing. Legal status U.S. government's positions on Area 51 The United States government has provided minimal information regarding Area 51. The area surrounding the lake is permanently off-limits to both civilian and normal military air traffic. Security clearances are checked regularly; cameras and weaponry are not allowed. Even military pilots training in the NAFR risk disciplinary action if they stray into the exclusionary "box" surrounding Groom's airspace. Surveillance is supplemented using buried motion sensors. Area 51 is a common destination for Janet, a small fleet of passenger aircraft operated on behalf of the Air Force to transport military personnel, primarily from Harry Reid International Airport. The United States Geological Survey (USGS) topographic map for the area only shows the long-disused Groom Mine, but USGS aerial photographs of the site in 1959 and 1968 were publicly available. A civil aviation chart published by the Nevada Department of Transportation shows a large restricted area, defined as part of the Nellis restricted airspace. The National Atlas shows the area as lying within the Nellis Air Force Base. There are higher resolution and newer images available from other satellite imagery providers, including Russian providers and the IKONOS. These show the runway markings, base facilities, aircraft, and vehicles. In 1998 USAF officially acknowledged the site's existence. On 25 June 2013, the CIA released an official history of the U-2 and OXCART projects which acknowledged that the U-2 was tested at Area 51, in response to a Freedom of Information Act request submitted in 2005 by Jeffrey T. Richelson of George Washington University's National Security Archive. It contains numerous references to Area 51 and Groom Lake, along with a map of the area. Media reports stated that releasing the CIA history was the first governmental acknowledgement of Area 51's existence; rather, it was the first official acknowledgement of specific activity at the site. Environmental lawsuit In 1994, five unnamed civilian contractors and the widows of contractors Walter Kasza and Robert Frost sued the Air Force and the United States Environmental Protection Agency. They alleged that they had been present when large quantities of unknown chemicals had been burned in open pits and trenches at Groom. Rutgers University biochemists analyzed biopsies from the complainants and found high levels of dioxin, dibenzofuran, and trichloroethylene in their body fat. The complainants alleged that they had sustained skin, liver, and respiratory injuries due to their work at Groom and that this had contributed to the deaths of Frost and Kasza. The suit sought compensation for the injuries, claiming that the Air Force had illegally handled toxic materials and that the EPA had failed in its duty to enforce the Resource Conservation and Recovery Act which governs the handling of dangerous materials. They also sought detailed information about the chemicals, hoping that this would facilitate the medical treatment of survivors. Congressman Lee H. Hamilton, former chairman of the House Intelligence Committee, told 60 Minutes reporter Lesley Stahl, "The Air Force is classifying all information about Area 51 in order to protect themselves from a lawsuit." The government invoked the State Secrets Privilege and petitioned U.S. District Judge Philip Pro to disallow disclosure of classified documents or examination of secret witnesses, claiming that this would expose classified information and threaten national security. Judge Pro rejected the government's argument, so President Bill Clinton issued a Presidential Determination exempting what it called "the Air Force's Operating Location Near Groom Lake, Nevada" from environmental disclosure laws. Consequently, Pro dismissed the suit due to lack of evidence. Turley appealed to the U.S. Court of Appeals for the Ninth Circuit on the grounds that the government was abusing its power to classify material. Secretary of the Air Force Sheila E. Widnall filed a brief which stated that disclosures of the materials present in the air and water near Groom "can reveal military operational capabilities or the nature and scope of classified operations." The Ninth Circuit rejected Turley's appeal and the U.S. Supreme Court refused to hear it, putting an end to the complainants' case. The President annually issues a determination continuing the Groom exception which is the only formal recognition that the government has ever given that Groom Lake is more than simply another part of the Nellis complex. An unclassified memo on the safe handling of F-117 Nighthawk material was posted on an Air Force web site in 2005. This discussed the same materials for which the complainants had requested information, which the government had claimed was classified. The memo was removed shortly after journalists became aware of it. Civil aviation identification In December 2007, airline pilots noticed that the base had appeared in their aircraft navigation systems' latest Jeppesen database revision with the ICAO airport identifier code of KXTA and listed as "Homey Airport". The probably inadvertent release of the airport data led to advice by the Aircraft Owners and Pilots Association (AOPA) that student pilots should be explicitly warned about KXTA, not to consider it as a waypoint or destination for any flight even though it now appears in public navigation databases. Security The perimeter of the base is marked out by orange posts and patrolled by guards in white pickup trucks and camouflage fatigues. The guards are popularly referred to as "camo dudes" by enthusiasts. The guards will not answer questions about their employers; however, according to the New York Daily News, there are indications they are employed through a contractor such as AECOM. Signage around the base perimeter advises that deadly force is authorized against trespassers. Technology is also heavily used to maintain the border of the base; this includes surveillance cameras and motion detectors. Some of these motion detectors are placed some distance away from the base on public land to notify guards of people approaching. 1974 Skylab photography Dwayne A. Day published "Astronauts and Area 51: the Skylab Incident" in The Space Review in January 2006. It was based on a memo written in 1974 to CIA director William Colby by an unknown CIA official. The memo reported that astronauts on board Skylab had inadvertently photographed a certain location: The name of the location was obscured, but the context led Day to believe that the subject was Groom Lake. Day wrote that "the CIA considered no other spot on Earth to be as sensitive as Groom Lake". Even within the agency's National Photographic Interpretation Center that handled classified reconnaissance satellite photographs, images of the site were removed from film rolls and stored separately as not all photo interpreters had security clearance for the information. The memo details debate between federal agencies regarding whether the images should be classified, with Department of Defense agencies arguing that it should and NASA and the State Department arguing that it should not be classified. The memo itself questions the legality of retroactively classifying unclassified images. The memo includes handwritten remarks, apparently by Director of Central Intelligence Colby: The declassified documents do not disclose the outcome of discussions regarding the Skylab imagery. The debate proved moot, as the photograph appeared in the Federal Government's Archive of Satellite Imagery along with the remaining Skylab photographs. 2019 shooting incident On 28 January 2019, an unidentified man drove through a security checkpoint near Mercury, Nevada, in an apparent attempt to enter the base. After an vehicle pursuit by base security, the man exited his vehicle carrying a "cylindrical object" and was shot dead by NNSS security officers and sheriff's deputies after refusing to obey requests to halt. There were no other injuries reported. UFO and other conspiracy theories Area 51 has become a focus of modern conspiracy theories due to its secretive nature and connection to classified aircraft research. Theories include: The storage, examination, and reverse engineering of crashed alien spacecraft, including material supposedly recovered at Roswell, the study of their occupants, and the manufacture of aircraft based on alien technology Meetings or joint undertakings with extraterrestrials The development of exotic energy weapons for the Strategic Defense Initiative (SDI) or other weapons programs The development of weather control The development of time travel and teleportation technology The development of exotic propulsion systems related to the Aurora Program Activities related to a shadowy one-world government or the Majestic 12 organization Many of the hypotheses concern underground facilities at Groom or at Papoose Lake (also known as "S-4 location"), south, and include claims of a transcontinental underground railroad system, a disappearing airstrip nicknamed the "Cheshire Airstrip", after Lewis Carroll's Cheshire cat, which briefly appears when water is sprayed onto its camouflaged asphalt, and engineering based on alien technology. In the mid-1950s, civilian aircraft flew under 20,000 feet while military aircraft flew up to 40,000 feet. The U-2 began flying above 60,000 feet and there was an increasing number of UFO sighting reports. Sightings occurred most often during early evening hours, when airline pilots flying west saw the U-2's silver wings reflect the setting sun, giving the aircraft a "fiery" appearance. Many sighting reports came to the Air Force's Project Blue Book, which investigated UFO sightings, through air-traffic controllers and letters to the government. The project checked U-2 and later OXCART flight records to eliminate the majority of UFO reports that it received during the late 1950s and 1960s, although it could not reveal to the letter writers the truth behind what they saw. Similarly, veterans of experimental projects such as OXCART at Area 51 agree that their work inadvertently prompted many of the UFO sightings and other rumors: They believe that the rumors helped maintain secrecy over Area 51's actual operations. The veterans deny the existence of a vast underground railroad system, although many of Area 51's operations did occur underground. Bob Lazar claimed in 1989 that he had worked at Area 51's "Sector Four (S-4)", said to be located underground inside the Papoose Range near Papoose Lake. He claimed that he was contracted to work with alien spacecraft that the government had in its possession. Similarly, the 1996 documentary Dreamland directed by Bruce Burgess included an interview with a 71-year-old mechanical engineer who claimed to be a former employee at Area 51 during the 1950s. His claims included that he had worked on a "flying disc simulator" which had been based on a disc originating from a crashed extraterrestrial craft and was used to train pilots. He also claimed to have worked with an extraterrestrial being named "J-Rod" and described as a "telepathic translator". In 2004, Dan Burisch (pseudonym of Dan Crain) claimed to have worked on cloning alien viruses at Area 51, also alongside the alien named "J-Rod". Burisch's scholarly credentials are the subject of much debate, as he was apparently working as a Las Vegas parole officer in 1989 while also earning a PhD at State University of New York (SUNY). In July 2019, more than 2,000,000 people responded to a joke proposal to storm Area 51 which appeared in an anonymous Facebook post. The event, scheduled for 20 September 2019, was billed as "Storm Area 51, They Can't Stop All of Us", an attempt to "see them aliens". Air Force spokeswoman Laura McAndrews said the government "would discourage anyone from trying to come into the area where we train American armed forces". Two music festivals in rural Nevada, AlienStock and Storm Area 51 Basecamp, were subsequently organized to capitalize on the popularity of the original Facebook event. Between 1,500 and 3,000 people showed up at the festivals, while over 150 people made the journey over several miles of rough roads to get near the gates to Area 51. Seven people were reportedly arrested at the event.

Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals or sound power level is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation. History The motivation for audio signal processing began at the beginning of the 20th century with inventions like the telephone, phonograph, and radio that allowed for the transmission and storage of audio signals. Audio processing was necessary for early radio broadcasting, as there were many problems with studio-to-transmitter links. The theory of signal processing and its application to audio was largely developed at Bell Labs in the mid 20th century. Claude Shannon and Harry Nyquist's early work on communication theory, sampling theory and pulse-code modulation (PCM) laid the foundations for the field. In 1957, Max Mathews became the first person to synthesize audio from a computer, giving birth to computer music. Major developments in digital audio coding and audio data compression include differential pulse-code modulation (DPCM) by C. Chapin Cutler at Bell Labs in 1950, linear predictive coding (LPC) by Fumitada Itakura (Nagoya University) and Shuzo Saito (Nippon Telegraph and Telephone) in 1966, adaptive DPCM (ADPCM) by P. Cummiskey, Nikil S. Jayant and James L. Flanagan at Bell Labs in 1973, discrete cosine transform (DCT) coding by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974, and modified discrete cosine transform (MDCT) coding by J. P. Princen, A. W. Johnson and A. B. Bradley at the University of Surrey in 1987. LPC is the basis for perceptual coding and is widely used in speech coding, while MDCT coding is widely used in modern audio coding formats such as MP3 and Advanced Audio Coding (AAC). Types Analog An analog audio signal is a continuous signal represented by an electrical voltage or current that is analogous to the sound waves in the air. Analog signal processing then involves physically altering the continuous signal by changing the voltage or current or charge via electrical circuits. Historically, before the advent of widespread digital technology, analog was the only method by which to manipulate a signal. Since that time, as computers and software have become more capable and affordable, digital signal processing has become the method of choice. However, in music applications, analog technology is often still desirable as it often produces nonlinear responses that are difficult to replicate with digital filters. Digital A digital representation expresses the audio waveform as a sequence of symbols, usually binary numbers. This permits signal processing using digital circuits such as digital signal processors, microprocessors and general-purpose computers. Most modern audio systems use a digital approach as the techniques of digital signal processing are much more powerful and efficient than analog domain signal processing. Applications Processing methods and application areas include storage, data compression, music information retrieval, speech processing, localization, acoustic detection, transmission, noise cancellation, acoustic fingerprinting, sound recognition, synthesis, and enhancement (e.g. equalization, filtering, level compression, echo and reverb removal or addition, etc.). Audio broadcasting Audio signal processing is used when broadcasting audio signals in order to enhance their fidelity or optimize for bandwidth or latency. In this domain, the most important audio processing takes place just before the transmitter. The audio processor here must prevent or minimize overmodulation, compensate for non-linear transmitters (a potential issue with medium wave and shortwave broadcasting), and adjust overall loudness to the desired level. Active noise control Active noise control is a technique designed to reduce unwanted sound. By creating a signal that is identical to the unwanted noise but with the opposite polarity, the two signals cancel out due to destructive interference. Audio synthesis Audio synthesis is the electronic generation of audio signals. A musical instrument that accomplishes this is called a synthesizer. Synthesizers can either imitate sounds or generate new ones. Audio synthesis is also used to generate human speech using speech synthesis. Audio effects Audio effects alter the sound of a musical instrument or other audio source. Common effects include distortion, often used with electric guitar in electric blues and rock music; dynamic effects such as volume pedals and compressors, which affect loudness; filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as chorus, flangers and phasers; pitch effects such as pitch shifters; and time effects, such as reverb and delay, which create echoing sounds and emulate the sound of different spaces. Musicians, audio engineers and record producers use effects units during live performances or in the studio, typically with electric guitar, bass guitar, electronic keyboard or electric piano. While effects are most frequently used with electric or electronic instruments, they can be used with any audio source, such as acoustic instruments, drums, and vocals.

In computer architecture, Amdahl's law (or Amdahl's argument) is a formula which gives the theoretical speedup in latency of the execution of a task at fixed workload that can be expected of a system whose resources are improved. It states that "the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used". It is named after computer scientist Gene Amdahl, and was presented at the American Federation of Information Processing Societies (AFIPS) Spring Joint Computer Conference in 1967. Amdahl's law is often used in parallel computing to predict the theoretical speedup when using multiple processors. For example, if a program needs 20 hours to complete using a single thread, but a one-hour portion of the program cannot be parallelized, therefore only the remaining 19 hours' () execution time can be parallelized, then regardless of how many threads are devoted to a parallelized execution of this program, the minimum execution time is always more than 1 hour. Hence, the theoretical speedup is less than 20 times the single thread performance, . Definition Amdahl's law can be formulated in the following way: where Slatency is the theoretical speedup of the execution of the whole task; s is the speedup of the part of the task that benefits from improved system resources; p is the proportion of execution time that the part benefiting from improved resources originally occupied. Furthermore, shows that the theoretical speedup of the execution of the whole task increases with the improvement of the resources of the system and that regardless of the magnitude of the improvement, the theoretical speedup is always limited by the part of the task that cannot benefit from the improvement. Amdahl's law applies only to the cases where the problem size is fixed. In practice, as more computing resources become available, they tend to get used on larger problems (larger datasets), and the time spent in the parallelizable part often grows much faster than the inherently serial work. In this case, Gustafson's law gives a less pessimistic and more realistic assessment of the parallel performance. Derivation A task executed by a system whose resources are improved compared to an initial similar system can be split up into two parts: a part that does not benefit from the improvement of the resources of the system; a part that benefits from the improvement of the resources of the system. An example is a computer program that processes files. A part of that program may scan the directory of the disk and create a list of files internally in memory. After that, another part of the program passes each file to a separate thread for processing. The part that scans the directory and creates the file list cannot be sped up on a parallel computer, but the part that processes the files can. The execution time of the whole task before the improvement of the resources of the system is denoted as . It includes the execution time of the part that would not benefit from the improvement of the resources and the execution time of the one that would benefit from it. The fraction of the execution time of the task that would benefit from the improvement of the resources is denoted by . The one concerning the part that would not benefit from it is therefore . Then: It is the execution of the part that benefits from the improvement of the resources that is accelerated by the factor after the improvement of the resources. Consequently, the execution time of the part that does not benefit from it remains the same, while the part that benefits from it becomes: The theoretical execution time of the whole task after the improvement of the resources is then: Amdahl's law gives the theoretical speedup in latency of the execution of the whole task at fixed workload , which yields Parallel programs If 30% of the execution time may be the subject of a speedup, p will be 0.3; if the improvement makes the affected part twice as fast, s will be 2. Amdahl's law states that the overall speedup of applying the improvement will be: For example, assume that we are given a serial task which is split into four consecutive parts, whose percentages of execution time are , , , and respectively. Then we are told that the 1st part is not sped up, so , while the 2nd part is sped up 5 times, so , the 3rd part is sped up 20 times, so , and the 4th part is sped up 1.6 times, so . By using Amdahl's law, the overall speedup is Notice how the 5 times and 20 times speedup on the 2nd and 3rd parts respectively don't have much effect on the overall speedup when the 4th part (48% of the execution time) is accelerated by only 1.6 times. Serial programs [[File:Optimizing-different-parts.svg|thumb|400px|Assume that a task has two independent parts, A and B. Part B takes roughly 25% of the time of the whole computation. By working very hard, one may be able to make this part 5 times faster, but this reduces the time of the whole computation only slightly. In contrast, one may need to perform less work to make part A perform twice as fast. This will make the computation much faster than by optimizing part B, even though part B'''s speedup is greater in terms of the ratio, (5 times versus 2 times).]] For example, with a serial program in two parts A and B for which and , if part B is made to run 5 times faster, that is and , then if part A is made to run 2 times faster, that is and , then Therefore, making part A to run 2 times faster is better than making part B to run 5 times faster. The percentage improvement in speed can be calculated as Improving part A by a factor of 2 will increase overall program speed by a factor of 1.60, which makes it 37.5% faster than the original computation. However, improving part B by a factor of 5, which presumably requires more effort, will achieve an overall speedup factor of 1.25 only, which makes it 20% faster. Optimizing the sequential part of parallel programs If the non-parallelizable part is optimized by a factor of , then It follows from Amdahl's law that the speedup due to parallelism is given by When , we have , meaning that the speedup is measured with respect to the execution time after the non-parallelizable part is optimized. When , If , and , then: Transforming sequential parts of parallel programs into parallelizable Next, we consider the case wherein the non-parallelizable part is reduced by a factor of , and the parallelizable part is correspondingly increased. Then It follows from Amdahl's law that the speedup due to parallelism is given by Relation to the law of diminishing returns Amdahl's law is often conflated with the law of diminishing returns, whereas only a special case of applying Amdahl's law demonstrates law of diminishing returns. If one picks optimally (in terms of the achieved speedup) what is to be improved, then one will see monotonically decreasing improvements as one improves. If, however, one picks non-optimally, after improving a sub-optimal component and moving on to improve a more optimal component, one can see an increase in the return. Note that it is often rational to improve a system in an order that is "non-optimal" in this sense, given that some improvements are more difficult or require larger development time than others. Amdahl's law does represent the law of diminishing returns if one is considering what sort of return one gets by adding more processors to a machine, if one is running a fixed-size computation that will use all available processors to their capacity. Each new processor added to the system will add less usable power than the previous one. Each time one doubles the number of processors the speedup ratio will diminish, as the total throughput heads toward the limit of 1/(1 − p''). This analysis neglects other potential bottlenecks such as memory bandwidth and I/O bandwidth. If these resources do not scale with the number of processors, then merely adding processors provides even lower returns. An implication of Amdahl's law is that to speed up real applications which have both serial and parallel portions, heterogeneous computing techniques are required. There are novel speedup and energy consumption models based on a more general representation of heterogeneity, referred to as the normal form heterogeneity, that support a wide range of heterogeneous many-core architectures. These modelling methods aim to predict system power efficiency and performance ranges, and facilitates research and development at the hardware and system software levels.

Ayahuasca is a South American psychoactive brew, traditionally used by Indigenous cultures and folk healers in Amazon and Orinoco basins for spiritual ceremonies, divination, and healing a variety of psychosomatic complaints. Originally restricted to areas of Peru, Brazil, Colombia and Ecuador, in the middle of 20th century it became widespread in Brazil in context of appearance of syncretic religions that uses ayahuasca as a sacrament, like Santo Daime, União do Vegetal and Barquinha, which blend elements of Amazonian Shamanism, Christianity, Kardecist Spiritism, and African-Brazilian religions such as Umbanda, Candomblé and Tambor de Mina, later expanding to several countries across all continents, notably the United States and Western Europe, and, more incipiently, in Eastern Europe, South Africa, Australia, and Japan. More recently, new phenomena regarding ayahuasca use have evolved and moved to urban centers in North America and Europe, with the emergence of neoshamanic hybrid rituals and spiritual and recreational drug tourism. Also, anecdotal evidence, studies conducted among ayahuasca consumers and clinical trials suggest that ayahuasca has broad therapeutic potential, especially for the treatment of substance dependence, anxiety, and mood disorders. Thus, currently, despite continuing to be used in a traditional way, ayahuasca is also consumed recreationally worldwide, as well as used in modern medicine. Ayahuasca is commonly made by the prolonged decoction of the stems of the Banisteriopsis caapi vine and the leaves of the Psychotria viridis shrub, although hundreds of species are used in addition or substitution (See "Preparation" below). P. viridis contains N,N-Dimethyltryptamine (DMT), a highly psychedelic substance, although orally inactive, and B. caapi is rich on harmala alkaloids, such as harmine, harmaline and tetrahydroharmine (THH), which can act as a monoamine oxidase inhibitor (MAOi), halting liver and gastrointestinal metabolism of DMT, allowing it to reach the systemic circulation and the brain, where it activates 5-HT1A/2A/2C receptors in frontal and paralimbic areas. Etymology Ayahuasca is the hispanicized (traditional) spelling of a word in the Quechuan languages, which are spoken in the Andean states of Ecuador, Bolivia, Peru, and Colombia—speakers of Quechuan languages who use the modern Alvarado orthography spell it ayawaska. This word refers both to the liana Banisteriopsis caapi, and to the brew prepared from it. In the Quechua languages, aya means "spirit, soul", or "corpse, dead body", and waska means "rope" or "woody vine", "liana". The word ayahuasca has been variously translated as "liana of the soul", "liana of the dead", and "spirit liana". In the cosmovision of its users, the ayahuasca is the vine that allows the spirit to wander detached from the body, entering the spiritual world, otherwise forbidden for the alive. In Brazil it is sometimes called hoasca or oasca. Although ayahuasca is the most widely used terminology in Peru, Bolivia, Ecuador and Brazil, the brew is known by many names throughout Northern South America: yagé (or yajé, from the Cofán language or iagê in Portuguese). Relatively spread use in Andean and Amazonian regions throughout the borders of Colombia, Peru, Ecuador and Brazil. Cofán people also uses oofa caapi (or kahpi/gahpi in Tupi–Guarani language or kaapi in proto-Arawak language), used to address both the brew and the B. caapi itself. Meaning "weed" or "thin leaf", was the word utilized by Spruce for naming the liana pinde (or pindê/pilde), used by the Colorado people patem (or nátema), from the Chicham languages shori, mii (or miiyagi) and uni, from the Yaminawa language nishi cobin, from the Shipibo language nixi pae, shuri, ondi, rambi and rame, from the Kashinawa language kaji, kadana and kadanapira, used by Tucano people kamarampi (or kamalampi) and hananeroca, from the Arawakan languages bakko, from Bora-Muiname language jono pase, useb by Ese'Ejja people uipa, from Guahibo language napa (or nepe/nepi), used by Tsáchila people Biaxije, from Camsá language Cipó ("liana") or Vegetal, in Portuguese language, used by União do Vegetal church members Daime or Santo Daime, meaning "give me" in Portuguese, the term was coined by Santo Daime's founder Mestre Irineu in the 1940s, from a prayer dai-me alegria, dai-me resistência ("give-me happyness, give me strength"). Daime members also uses the words Luz ("light") or Santa Luz ("holy light") Some nomenclature are created by the cultural and symbolic signification of ayahuasca, with names like planta professora ("plant teacher"), professor dos professores ("teacher of the teachers"), sagrada medicina ("holy medicine") or la purga ("the purge"). In the last decades, two new important terminologies emerged. Both are commonly used in the Western world in neoshamanic, recreative or pharmaceutical contexts to address ayahuasca-like substances created without the traditional botanical species, due to it being expensive and/or hard to find in these countries. These concepts are surrounded by some controversies involving patents, commodification and biopiracy: Anahuasca (ayahuasca analogues). A term usually used to refers the ayahuasca produced with different plant species as sources of DMT (like Mimosa hostilis) or β-carbolines (like Peganum harmala). Pharmahuasca (pharmaceutical ayahuasca). Indicate the pills produced with freebase DMT, synthetic harmaline, MAOi medications (such as moclobemide) and other isolated/purified compounds or extracts History Evidence of Banisteriopsis caapi use in South America dates back at least 1,000 years, as demonstrated by a bundle containing the residue of the beta-carboline harmine and various other preserved psychoactive alkaloids such as bufotenin and cocaine in a cave in southwestern Bolivia, discovered in 2010. In the 16th century, Christian missionaries from Spain first encountered Indigenous people in the western Amazonian basin of South America using ayahuasca; their earliest reports described it as "the work of the devil". In 1905, the active chemical constituent of B. caapi was named telepathine, but in 1927, it was found to be identical to a chemical already isolated from Peganum harmala and was given the name harmine. Beat writer William S. Burroughs read a paper by Richard Evans Schultes on the subject and while traveling through South America in the early 1950s sought out ayahuasca in the hopes that it could relieve or cure opiate addiction (see The Yage Letters). Ayahuasca became more widely known when the McKenna brothers published their experience in the Amazon in True Hallucinations. Dennis McKenna later studied pharmacology, botany, and chemistry of ayahuasca and oo-koo-he, which became the subject of his master's thesis. Richard Evans Schultes allowed Claudio Naranjo to make a special journey by canoe up the Amazon River to study ayahuasca with the South American Indians. He brought back samples of the beverage and published the first scientific description of the effects of its active alkaloids. In Brazil, a number of modern religious movements based on the use of ayahuasca have emerged, the most famous being Santo Daime, Barquinha and the União do Vegetal (or UDV), usually in an animistic context that may be shamanistic or, more often (as with Santo Daime and the UDV), integrated with Christianity. Both Santo Daime and União do Vegetal now have members and churches throughout the world. Similarly, the US and Europe have started to see new religious groups develop in relation to increased ayahuasca use. Some Westerners have teamed up with shamans in the Amazon forest regions, forming ayahuasca healing retreats that claim to be able to cure mental and physical illness and allow communication with the spirit world. In recent years, the brew has been popularized by Wade Davis (One River), English novelist Martin Goodman in I Was Carlos Castaneda, Chilean novelist Isabel Allende, writer Kira Salak, author Jeremy Narby (The Cosmic Serpent), author Jay Griffiths (Wild: An Elemental Journey), American novelist Steven Peck, radio personality Robin Quivers,, writer Paul Theroux (Figures in a Landscape: People and Places) and NFL quarterback Aaron Rodgers. Preparation Sections of Banisteriopsis caapi vine are macerated and boiled alone or with leaves from any of a number of other plants, including Psychotria viridis (chacruna), Diplopterys cabrerana (also known as chaliponga and chacropanga), and Mimosa tenuiflora, among other ingredients which can vary greatly from one shaman to the next. The resulting brew may contain the powerful psychedelic drug DMT and MAO inhibiting harmala alkaloids, which are necessary to make the DMT orally active. The traditional making of ayahuasca follows a ritual process that requires the user to pick the lower Chacruna leaf at sunrise, then say a prayer. The vine must be "cleaned meticulously with wooden spoons" and pounded "with wooden mallets until it's fibre." Brews can also be made with plants that do not contain DMT, Psychotria viridis being replaced by plants such as Justicia pectoralis, Brugmansia, or sacred tobacco, also known as mapacho (Nicotiana rustica), or sometimes left out with no replacement. This brew varies radically from one batch to the next, both in potency and psychoactive effect, based mainly on the skill of the shaman or brewer, as well as other admixtures sometimes added and the intent of the ceremony. Natural variations in plant alkaloid content and profiles also affect the final concentration of alkaloids in the brew, and the physical act of cooking may also serve to modify the alkaloid profile of harmala alkaloids. The actual preparation of the brew takes several hours, often taking place over the course of more than one day. After adding the plant material, each separately at this stage, to a large pot of water, it is boiled until the water is reduced by half in volume. The individual brews are then added together and brewed until reduced significantly. This combined brew is what is taken by participants in ayahuasca ceremonies. Traditional use The uses of ayahuasca in traditional societies in South America vary greatly. Some cultures do use it for shamanic purposes, but in other cases, it is consumed socially among friends, in order to learn more about the natural environment, and even in order to visit friends and family who are far away. Nonetheless, people who work with ayahuasca in non-traditional contexts often align themselves with the philosophies and cosmologies associated with ayahuasca shamanism, as practiced among Indigenous peoples like the Urarina of the Peruvian Amazon. Dietary taboos are often associated with the use of ayahuasca, although these seem to be specific to the culture around Iquitos, Peru, a major center of ayahuasca tourism. In the rainforest, these taboos tend towards the purification of one's self—abstaining from spicy and heavily seasoned foods, excess fat, salt, caffeine, acidic foods (such as citrus) and sex before, after, or during a ceremony. A diet low in foods containing tyramine has been recommended, as the speculative interaction of tyramine and MAOIs could lead to a hypertensive crisis; however, evidence indicates that harmala alkaloids act only on MAO-A, in a reversible way similar to moclobemide (an antidepressant that does not require dietary restrictions). Dietary restrictions are not used by the highly urban Brazilian ayahuasca church União do Vegetal, suggesting the risk is much lower than perceived and probably non-existent. Ceremony and the role of shamans Shamans, curanderos and experienced users of ayahuasca advise against consuming ayahuasca when not in the presence of one or several well-trained shamans. In some areas, there are purported brujos (Spanish for "witches") who masquerade as real shamans and who entice tourists to drink ayahuasca in their presence. Shamans believe one of the purposes for this is to steal one's energy and/or power, of which they believe every person has a limited stockpile. The shamans lead the ceremonial consumption of the ayahuasca beverage, in a rite that typically takes place over the entire night. During the ceremony, the effect of the drink lasts for hours. Prior to the ceremony, participants are instructed to abstain from spicy foods, red meat and sex. The ceremony is usually accompanied with purging which include vomiting and diarrhea, which is believed to release built-up emotions and negative energy. Traditional brew Traditional ayahuasca brews are usually made with Banisteriopsis caapi as an MAOI, while dimethyltryptamine sources and other admixtures vary from region to region. There are several varieties of caapi, often known as different "colors", with varying effects, potencies, and uses. DMT admixtures: Psychotria viridis (Chacruna) – leaves Diplopterys cabrerana (Chaliponga, Chagropanga, Banisteriopsis rusbyana) – leaves Psychotria carthagenensis (Amyruca) – leaves Mimosa tenuiflora (M. hostilis) - root bark Other common admixtures: Justicia pectoralis Brugmansia sp. (Toé) Opuntia sp. Epiphyllum sp. Cyperus sp. Nicotiana rustica (Mapacho, variety of tobacco) Ilex guayusa, a relative of yerba mate Lygodium venustum, (Tchai del monte) Phrygilanthus eugenioides and Clusia sp (both called Miya) Lomariopsis japurensis (Shoka) Common admixtures with their associated ceremonial values and spirits: Ayahuma bark: Cannon Ball tree. Provides protection and is used in healing susto (soul loss from spiritual fright or trauma). Capirona bark: Provides cleansing, balance and protection. It is noted for its smooth bark, white flowers, and hard wood. Chullachaki caspi bark (Brysonima christianeae): Provides cleansing to the physical body. Used to transcend physical body ailments. Lopuna blanca bark: Provides protection. Punga amarilla bark: Yellow Punga. Provides protection. Used to pull or draw out negative spirits or energies. Remo caspi bark: Oar Tree. Used to move dense or dark energies. Wyra (huaira) caspi bark (Cedrelinga catanaeformis): Air Tree. Used to create purging, transcend gastro/intestinal ailments, calm the mind, and bring tranquility. Shiwawaku bark: Brings purple medicine to the ceremony. Uchu sanango: Head of the sanango plants. Huacapurana: Giant tree of the Amazon with very hard bark. Bobinsana: Mermaid Spirit. Provides major heart chakra opening, healing of emotions and relationships. Non-traditional usage In the late 20th century, the practice of ayahuasca drinking began spreading to Europe, North America and elsewhere. The first ayahuasca churches, affiliated with the Brazilian Santo Daime, were established in the Netherlands. A legal case was filed against two of the Church's leaders, Hans Bogers (one of the original founders of the Dutch Santo Daime community) and Geraldine Fijneman (the head of the Amsterdam Santo Daime community). Bogers and Fijneman were charged with distributing a controlled substance (DMT); however, the prosecution was unable to prove that the use of ayahuasca by members of the Santo Daime constituted a sufficient threat to public health and order such that it warranted denying their rights to religious freedom under ECHR Article 9. The 2001 verdict of the Amsterdam district court is an important precedent. Since then groups that are not affiliated to the Santo Daime have used ayahuasca, and a number of different "styles" have been developed, including non-religious approaches. Ayahuasca analogs In modern Europe and North America, ayahuasca analogs are often prepared using non-traditional plants which contain the same alkaloids. For example, seeds of the Syrian rue plant can be used as a substitute for the ayahuasca vine, and the DMT-rich Mimosa hostilis is used in place of chacruna. Australia has several indigenous plants which are popular among modern ayahuasqueros there, such as various DMT-rich species of Acacia. The name "ayahuasca" specifically refers to a botanical decoction that contains Banisteriopsis caapi. A synthetic version, known as pharmahuasca, is a combination of an appropriate MAOI and typically DMT. In this usage, the DMT is generally considered the main psychoactive active ingredient, while the MAOI merely preserves the psychoactivity of orally ingested DMT, which would otherwise be destroyed in the gut before it could be absorbed in the body. In contrast, traditionally among Amazonian tribes, the B. Caapi vine is considered to be the "spirit" of ayahuasca, the gatekeeper, and guide to the otherworldly realms. Brews similar to ayahuasca may be prepared using several plants not traditionally used in South America: DMT admixtures: Acacia maidenii (Maiden's wattle) – bark *not all plants are "active strains", meaning some plants will have very little DMT and others larger amounts Acacia phlebophylla, and other Acacias, most commonly employed in Australia – bark Anadenanthera peregrina, A. colubrina, A. excelsa, A. macrocarpa Desmanthus illinoensis (Illinois bundleflower) – root bark is mixed with a native source of beta-Carbolines (e.g., passion flower in North America) to produce a hallucinogenic drink called prairiehuasca. MAOI admixtures: Harmal (Peganum harmala, Syrian rue) – seeds Passion flower synthetic MAOIs, especially RIMAs (due to the dangers presented by irreversible MAOIs) Effects Adverse effects Vomiting can follow ayahuasca ingestion and may harm people with conditions such as esophagus fissure, gastric ulcer, early pregnancy and similar. Vomiting is considered by many shamans and experienced users of ayahuasca to be a purging and an essential part of the experience, representing the release of negative energy and emotions built up over the course of one's life. Others report purging in the form of diarrhea and hot/cold flashes. The ingestion of ayahuasca can also cause significant but temporary emotional and psychological distress. People that take ayahuasca with an active history of psychiatric disorders such as schizophrenia, psychosis, personality disorders, or bipolar disorder, among others, are at high risk of having persisting effects after the session. Excessive use could possibly lead to serotonin syndrome (although serotonin syndrome has never been specifically caused by ayahuasca except in conjunction with certain anti-depressants like SSRIs). Depending on dosage, the temporary non-entheogenic effects of ayahuasca can include tremors, nausea, vomiting, diarrhea, autonomic instability, hyperthermia, sweating, motor function impairment, sedation, relaxation, vertigo, dizziness, and muscle spasms which are primarily caused by the harmala alkaloids in ayahuasca. Long-term negative effects are not known. A few deaths linked to participation in the consumption of ayahuasca have been reported. Some of the deaths may have been due to unscreened preexisting cardiovascular conditions, interaction with drugs, such as antidepressants, recreational drugs, caffeine (due to the CYP1A2 inhibition of the harmala alkaloids), nicotine (from drinking tobacco tea for purging/cleansing), or from improper/irresponsible use due to behavioral risks or possible drug to drug interactions. Psychological effects People who have consumed ayahuasca report having mystical experiences and spiritual revelations regarding their purpose on earth, the true nature of the universe, and deep insight into how to be the best person they possibly can. Many people also report therapeutic effects, especially around depression and personal traumas. This is viewed by many as a spiritual awakening and what is often described as a near-death experience or rebirth. It is often reported that individuals feel they gain access to higher spiritual dimensions and make contact with various spiritual or extra-dimensional beings who can act as guides or healers. The experiences that people have while under the influence of ayahuasca are also culturally influenced. Westerners typically describe experiences with psychological terms like "ego death" and understand the hallucinations as repressed memories or metaphors of mental states. However, at least in Iquitos, Peru (a center of ayahuasca ceremonies), those from the area describe the experiences more in terms of the actions in the body and understand the visions as reflections of their environment, sometimes including the person who they believe caused their illness, as well as interactions with spirits. Recently, ayahuasca has been found to interact specifically with the visual cortex of the brain. In one study, de Araujo et al. measured the activity in the visual cortex when they showed participants photographs. Then, they measured the activity when the individuals closed their eyes. In the control group, the cortex was activated when looking at the photos, and less active when the participant closed his eyes; however, under the influence of ayahuasca and DMT, even with closed eyes, the cortex was just as active as when looking at the photographs. This study suggests that ayahuasca activates a complicated network of vision and memory which heightens the internal reality of the participants. It is claimed that people may experience profound positive life changes subsequent to consuming ayahuasca, by author Don Jose Campos and others. Potential therapeutic effects There are potential antidepressant and anxiolytic effects of ayahuasca. For example, in 2018 it was reported that a single dose of ayahuasca significantly reduced symptoms of treatment-resistant depression in a small placebo-controlled trial. More specifically, statistically significant reductions of up to 82% in depressive scores were observed between baseline and 1, 7 and 21 days after ayahuasca administration, as measured on the Hamilton Rating Scale for Depression (HAM-D), the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Anxious-Depression subscale of the Brief Psychiatric Rating Scale (BPRS). Other placebo-controlled research has provided evidence that ayahuasca can help improve self-perceptions in those with social anxiety disorder. Ayahuasca has also been studied for the treatment of addictions and shown to be effective, with lower Addiction Severity Index scores seen in users of ayahuasca compared to controls. Ayahuasca users have also been seen to consume less alcohol. Chemistry and pharmacology Harmala alkaloids are MAO-inhibiting beta-carbolines. The three most studied harmala alkaloids in the B. caapi vine are harmine, harmaline and tetrahydroharmine. Harmine and harmaline are selective and reversible inhibitors of monoamine oxidase A (MAO-A), while tetrahydroharmine is a weak serotonin reuptake inhibitor (SRI). Individual polymorphisms of the cytochrome P450-2D6 enzyme affect the ability of individuals to metabolize harmine. Legal status Internationally, DMT is a Schedule I drug under the Convention on Psychotropic Substances. The Commentary on the Convention on Psychotropic Substances notes, however, that the plants containing it are not subject to international control: A fax from the Secretary of the International Narcotics Control Board (INCB) to the Netherlands Ministry of Public Health sent in 2001 goes on to state that "Consequently, preparations (e.g. decoctions) made of these plants, including ayahuasca, are not under international control and, therefore, not subject to any of the articles of the 1971 Convention." Despite the INCB's 2001 affirmation that ayahuasca is not subject to drug control by international convention, in its 2010 Annual Report the Board recommended that governments consider controlling (i.e. criminalizing) ayahuasca at the national level. This recommendation by the INCB has been criticized as an attempt by the Board to overstep its legitimate mandate and as establishing a reason for governments to violate the human rights (i.e., religious freedom) of ceremonial ayahuasca drinkers. Under American federal law, DMT is a Schedule I drug that is illegal to possess or consume; however, certain religious groups have been legally permitted to consume ayahuasca. A court case allowing the União do Vegetal to import and use the tea for religious purposes in the United States, Gonzales v. O Centro Espírita Beneficente União do Vegetal, was heard by the U.S. Supreme Court on November 1, 2005; the decision, released February 21, 2006, allows the UDV to use the tea in its ceremonies pursuant to the Religious Freedom Restoration Act. In a similar case an Ashland, Oregon-based Santo Daime church sued for their right to import and consume ayahuasca tea. In March 2009, U.S. District Court Judge Panner ruled in favor of the Santo Daime, acknowledging its protection from prosecution under the Religious Freedom Restoration Act. In 2017 the Santo Daime Church Céu do Montréal in Canada received religious exemption to use ayahuasca as a sacrament in their rituals. Religious use in Brazil was legalized after two official inquiries into the tea in the mid-1980s, which concluded that ayahuasca is not a recreational drug and has valid spiritual uses. In France, Santo Daime won a court case allowing them to use the tea in early 2005; however, they were not allowed an exception for religious purposes, but rather for the simple reason that they did not perform chemical extractions to end up with pure DMT and harmala and the plants used were not scheduled. Four months after the court victory, the common ingredients of ayahuasca as well as harmala were declared stupéfiants, or narcotic schedule I substances, making the tea and its ingredients illegal to use or possess. In June 2019, Oakland, California, decriminalized natural entheogens. The City Council passed the resolution in a unanimous vote, ending the investigation and imposition of criminal penalties for use and possession of entheogens derived from plants or fungi. The resolution states: "Practices with Entheogenic Plants have long existed and have been considered to be sacred to human cultures and human interrelationships with nature for thousands of years, and continue to be enhanced and improved to this day by religious and spiritual leaders, practicing professionals, mentors, and healers throughout the world, many of whom have been forced underground." In January 2020, Santa Cruz, California, and in September 2020, Ann Arbor, Michigan, decriminalized natural entheogens. Intellectual property issues Ayahuasca has stirred debate regarding intellectual property protection of traditional knowledge. In 1986 the US Patent and Trademarks Office (PTO) allowed the granting of a patent on the ayahuasca vine B. caapi. It allowed this patent based on the assumption that ayahuasca's properties had not been previously described in writing. Several public interest groups, including the Coordinating Body of Indigenous Organizations of the Amazon Basin (COICA) and the Coalition for Amazonian Peoples and Their Environment (Amazon Coalition) objected. In 1999 they brought a legal challenge to this patent which had granted a private US citizen "ownership" of the knowledge of a plant that is well-known and sacred to many Indigenous peoples of the Amazon, and used by them in religious and healing ceremonies. Later that year the PTO issued a decision rejecting the patent, on the basis that the petitioners' arguments that the plant was not "distinctive or novel" were valid; however, the decision did not acknowledge the argument that the plant's religious or cultural values prohibited a patent. In 2001, after an appeal by the patent holder, the US Patent Office reinstated the patent, albeit to only a specific plant and its asexually reproduced offspring. The law at the time did not allow a third party such as COICA to participate in that part of the reexamination process. The patent, held by US entrepreneur Loren Miller, expired in 2003.

In computer science, an abstract data type (ADT) is a mathematical model for data types, defined by its behavior (semantics) from the point of view of a user of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations. This mathematical model contrasts with data structures, which are concrete representations of data, and are the point of view of an implementer, not a user. Formally, an ADT may be defined as a "class of objects whose logical behavior is defined by a set of values and a set of operations"; this is analogous to an algebraic structure in mathematics. What is meant by "behaviour" varies by author, with the two main types of formal specifications for behavior being axiomatic (algebraic) specification and an abstract model; these correspond to axiomatic semantics and operational semantics of an abstract machine, respectively. Some authors also include the computational complexity ("cost"), both in terms of time (for computing operations) and space (for representing values). In practice, many common data types are not ADTs, as the abstraction is not perfect, and users must be aware of issues like arithmetic overflow that are due to the representation. For example, integers are often stored as fixed-width values (32-bit or 64-bit binary numbers), and thus experience integer overflow if the maximum value is exceeded. ADTs are a theoretical concept, in computer science, used in the design and analysis of algorithms, data structures, and software systems, and do not correspond to specific features of computer languages—mainstream computer languages do not directly support formally specified ADTs. However, various language features correspond to certain aspects of ADTs, and are easily confused with ADTs proper; these include abstract types, opaque data types, protocols, and design by contract. ADTs were first proposed by Barbara Liskov and Stephen N. Zilles in 1974, as part of the development of the CLU language. Discussion For example, integers are an ADT, defined as the values ..., −2, −1, 0, 1, 2, ..., and by the operations of addition, subtraction, multiplication, and division, together with greater than, less than, etc., which behave according to familiar mathematics (with care for integer division), independently of how the integers are represented by the computer. Explicitly, "behavior" includes obeying various axioms (associativity and commutativity of addition, etc.), and preconditions on operations (cannot divide by zero). Typically integers are represented in a data structure as binary numbers, most often as two's complement, but might be binary-coded decimal or in ones' complement, but for most purposes, the user can work with the abstraction rather than the concrete choice of representation, and can simply use the data as if the type were truly abstract. An ADT consists not only of operations but also of a domain of values and of constraints on the defined operations. An "interface" typically refers only to the operations, and perhaps some of the constraints on the operations, such as pre-conditions and post-conditions; but not to other constraints, such as relations between the operations. For example, an abstract stack, which is a last-in-first-out structure, could be defined by three operations: push, that inserts a data item onto the stack; pop, that removes a data item from it; and peek or top, that accesses a data item on top of the stack without removal. An abstract queue, which is a first-in-first-out structure, would also have three operations: enqueue, that inserts a data item into the queue; dequeue, that removes the first data item from it; and front, that accesses and serves the first data item in the queue. If these were the entire definitions, there would be no way of differentiating these two data types and their very different expected ordering behavior. Thus, a constraint is introduced that for a stack specifies that each pop always returns (and removes) the most recently pushed item that has not been popped yet, and for a queue (in contrast) specifies that pop operates on the least recently pushed item. When analyzing the efficiency of algorithms, one may also specify that all operations take the same time no matter how many data items have been pushed into the stack and that the stack uses a constant amount of storage for each element. However, time bounds are not always considered part of the definition of an ADT. Abstract data types are purely theoretical entities, used (among other things) to simplify the description of abstract algorithms, to classify and evaluate data structures, and to formally describe the type systems of programming languages. However, an ADT may be implemented by specific data types or data structures, in many ways and in many programming languages; or described in a formal specification language. ADTs are often implemented as modules: the module's interface declares procedures that correspond to the ADT operations, sometimes with comments that describe the constraints. This information hiding strategy allows the implementation of the module to be changed without disturbing the client programs. The term abstract data type can also be regarded as a generalized approach of a number of algebraic structures, such as lattices, groups, and rings. The notion of abstract data types is related to the concept of data abstraction, important in object-oriented programming and design by contract methodologies for software development. Definition An abstract data type is defined as a mathematical model of the data objects that make up a data type as well as the functions that operate on these objects. There are no standard conventions for defining them. A broad division may be drawn between "imperative" (or "operational") and "functional" (or "axiomatic") definition styles. Imperative-style definition In the theory of imperative programming languages, an abstract data structure is conceived as an entity that is mutable—meaning that it may be in different states at different times. Some operations may change the state of the ADT; therefore, the order in which operations are evaluated is important, and the same operation on the same entities may have different effects if executed at different times. This is analogous to the instructions of a computer or the commands and procedures of an imperative language. To underscore this view, it is customary to say that the operations are executed or applied, rather than evaluated, similar to the imperative style often used when describing abstract algorithms. (See The Art of Computer Programming by Donald Knuth for more details). Abstract variable Imperative-style definitions of ADT often depend on the concept of an abstract variable, which may be regarded as the simplest non-trivial ADT. An abstract variable V is a mutable entity that admits two operations: store(V, x) where x is a value of unspecified nature; fetch(V), that yields a value, with the constraint that fetch(V) always returns the value x used in the most recent store(V, x) operation on the same variable V. Fetching before storing can be disallowed, defined to have a certain result, or (less desirably), leave the behavior unspecified. As in many programming languages, the operation store(V, x) is often written V ← x (or some similar notation), and fetch(V) is implied whenever a variable V is used in a context where a value is required. Thus, for example, V ← V + 1 is commonly understood to be a shorthand for store(V,fetch(V) + 1). In this definition, it is implicitly assumed that names are always distinct: storing a value into a variable U has no effect on the state of a distinct variable V. To make this assumption explicit, one could add the constraint that if U and V are distinct variables, the sequence { store(U, x); store(V, y) } is equivalent to { store(V, y); store(U, x) }. More generally, ADT definitions often assume that any operation that changes the state of one ADT instance has no effect on the state of any other instance of the same ADT, unless the ADT axioms define certain instances as connected (see aliased) in a specific way. The most common such connections include: Aliasing, in which two or more names refer to the exact same data object. Composition, in which an ADT is defined to contain instances of (the same or other) ADTs. Reference, in which an ADT is defined to refer to instance of (the same or other) ADTs. For example, when extending the definition of an abstract variable to include abstract records, operations upon a field F of a record variable R, clearly involve F, which is distinct from, but also a part of, R. The definition of an ADT may restrict the stored value(s) for its instances, to members of a specific set X called the range of those variables. For example, an ADT for an aggregate such as a Stack or Queue, may constrain all items in the queue to be integers, or at least to all be of a single type (see homogeneity). As in programming languages, such restrictions may simplify the description and analysis of algorithms, and improve its readability. Note that this definition does not imply anything about the result of evaluating fetch(V) when V is un-initialized, that is, before performing any store operation on V. An algorithm that does so may be considered invalid, either (a) because the ADT prohibits such an operation, or (b) simply because its effect is not defined by the ADT. However, there are some important algorithms whose efficiency strongly depends on the assumption that such a fetch is legal, and returns some arbitrary value in the variable's range.) Instance creation Some algorithms need to create new instances of some ADT (such as new variables, or new stacks). To describe such algorithms, one usually includes in the ADT definition a create() operation that yields an instance of the ADT, usually with axioms equivalent to the result of create() is distinct from any instance already in use by the algorithm. This axiom may be strengthened to exclude also partial aliasing with other instances. For practical use, such as axiom may still allow implementations of create() to yield a previously created instance that has become inaccessible to the program; however, defining that such an instance even is "the same" is difficult, especially in the abstract (though even a re-used block of memory is only "the same object" in certain senses). Example: abstract stack (imperative) As another example, an imperative-style definition of an abstract stack could specify that the state of a stack S can be modified only by the operations push(S, x), where x is some value of unspecified nature; pop(S), that yields a value as a result, with the constraint that For any value x and any abstract variable V, the sequence of operations { push(S, x); V ← pop(S) } is equivalent to V ← x. Since the assignment V ← x, by definition, cannot change the state of S, this condition implies that V ← pop(S) restores S to the state it had before the push(S, x). From this condition and from the properties of abstract variables, it follows, for example, that the sequence { push(S, x); push(S, y); U ← pop(S); push(S, z); V ← pop(S); W ← pop(S) } where x, y, and z are any values, and U, V, W are pairwise distinct variables, is equivalent to { U ← y; V ← z; W ← x } Here it is implicitly assumed that operations on a stack instance do not modify the state of any other ADT instance, including other stacks; that is, For any values x, y, and any distinct stacks S and T, the sequence { push(S, x); push(T, y) } is equivalent to { push(T, y); push(S, x) }. An abstract stack definition usually includes also a Boolean-valued function empty(S) and a create() operation that returns a stack instance, with axioms equivalent to create() ≠ S for any prior stack S (a newly created stack is distinct from all previous stacks); empty(create()) (a newly created stack is empty); not empty(push(S, x)) (pushing something into a stack makes it non-empty). Single-instance style Sometimes an ADT is defined as if only one instance of it existed during the execution of the algorithm, and all operations were applied to that instance, which is not explicitly notated. For example, the abstract stack above could have been defined with operations push(x) and pop(), that operate on the only existing stack. ADT definitions in this style can be easily rewritten to admit multiple coexisting instances of the ADT, by adding an explicit instance parameter (like S in the previous example) to every operation that uses or modifies the implicit instance. On the other hand, some ADTs cannot be meaningfully defined without assuming multiple instances. This is the case when a single operation takes two distinct instances of the ADT as parameters. For an example, consider augmenting the definition of the abstract stack with an operation compare(S, T) that checks whether the stacks S and T contain the same items in the same order. Functional-style definition Another way to define an ADT, closer to the spirit of functional programming, is to consider each state of the structure as a separate entity. In this view, any operation that modifies the ADT is modelled as a mathematical function that takes the old state as an argument and returns the new state as part of the result. Unlike the imperative operations, these functions have no side effects. Therefore, the order in which they are evaluated is immaterial, and the same operation applied to the same arguments (including the same input states) will always return the same results (and output states). In the functional view, in particular, there is no way (or need) to define an "abstract variable" with the semantics of imperative variables (namely, with fetch and store operations). Instead of storing values into variables, one passes them as arguments to functions. Example: abstract stack (functional) For example, a complete functional-style definition of an abstract stack could use the three operations: push: takes a stack state and an arbitrary value, returns a stack state; top: takes a stack state, returns a value; pop: takes a stack state, returns a stack state. In a functional-style definition there is no need for a create operation. Indeed, there is no notion of "stack instance". The stack states can be thought of as being potential states of a single stack structure, and two-stack states that contain the same values in the same order are considered to be identical states. This view actually mirrors the behavior of some concrete implementations, such as linked lists with hash cons. Instead of create(), a functional-style definition of an abstract stack may assume the existence of a special stack state, the empty stack, designated by a special symbol like Λ or "()"; or define a bottom() operation that takes no arguments and returns this special stack state. Note that the axioms imply that push(Λ, x) ≠ Λ. In a functional-style definition of a stack one does not need an empty predicate: instead, one can test whether a stack is empty by testing whether it is equal to Λ. Note that these axioms do not define the effect of top(s) or pop(s), unless s is a stack state returned by a push. Since push leaves the stack non-empty, those two operations are undefined (hence invalid) when s = Λ. On the other hand, the axioms (and the lack of side effects) imply that push(s, x) = push(t, y) if and only if x = y and s = t. As in some other branches of mathematics, it is customary to assume also that the stack states are only those whose existence can be proved from the axioms in a finite number of steps. In the abstract stack example above, this rule means that every stack is a finite sequence of values, that becomes the empty stack (Λ) after a finite number of pops. By themselves, the axioms above do not exclude the existence of infinite stacks (that can be popped forever, each time yielding a different state) or circular stacks (that return to the same state after a finite number of pops). In particular, they do not exclude states s such that pop(s) = s or push(s, x) = s for some x. However, since one cannot obtain such stack states with the given operations, they are assumed "not to exist". Whether to include complexity Aside from the behavior in terms of axioms, it is also possible to include, in the definition of an ADT operation, their algorithmic complexity. Alexander Stepanov, designer of the C++ Standard Template Library, included complexity guarantees in the STL specification, arguing: Advantages Encapsulation Abstraction provides a promise that any implementation of the ADT has certain properties and abilities; knowing these is all that is required to make use of an ADT object. Localization of change Code that uses an ADT object will not need to be edited if the implementation of the ADT is changed. Since any changes to the implementation must still comply with the interface, and since code using an ADT object may only refer to properties and abilities specified in the interface, changes may be made to the implementation without requiring any changes in code where the ADT is used. Flexibility Different implementations of the ADT, having all the same properties and abilities, are equivalent and may be used somewhat interchangeably in code that uses the ADT. This gives a great deal of flexibility when using ADT objects in different situations. For example, different implementations of the ADT may be more efficient in different situations; it is possible to use each in the situation where they are preferable, thus increasing overall efficiency. Typical operations Some operations that are often specified for ADTs (possibly under other names) are compare(s, t), that tests whether two instances' states are equivalent in some sense; hash(s), that computes some standard hash function from the instance's state; print(s) or show(s), that produces a human-readable representation of the instance's state. In imperative-style ADT definitions, one often finds also create(), that yields a new instance of the ADT; initialize(s), that prepares a newly created instance s for further operations, or resets it to some "initial state"; copy(s, t), that puts instance s in a state equivalent to that of t; clone(t), that performs s ← create(), copy(s, t), and returns s; free(s) or destroy(s), that reclaims the memory and other resources used by s. The free operation is not normally relevant or meaningful, since ADTs are theoretical entities that do not "use memory". However, it may be necessary when one needs to analyze the storage used by an algorithm that uses the ADT. In that case, one needs additional axioms that specify how much memory each ADT instance uses, as a function of its state, and how much of it is returned to the pool by free. Examples Some common ADTs, which have proved useful in a great variety of applications, are Collection Container List String Set Multiset Map Multimap Graph Tree Stack Queue Priority queue Double-ended queue Double-ended priority queue Each of these ADTs may be defined in many ways and variants, not necessarily equivalent. For example, an abstract stack may or may not have a count operation that tells how many items have been pushed and not yet popped. This choice makes a difference not only for its clients but also for the implementation. Abstract graphical data type An extension of ADT for computer graphics was proposed in 1979: an abstract graphical data type (AGDT). It was introduced by Nadia Magnenat Thalmann, and Daniel Thalmann. AGDTs provide the advantages of ADTs with facilities to build graphical objects in a structured way. Implementation Implementing an ADT means providing one procedure or function for each abstract operation. The ADT instances are represented by some concrete data structure that is manipulated by those procedures, according to the ADT's specifications. Usually, there are many ways to implement the same ADT, using several different concrete data structures. Thus, for example, an abstract stack can be implemented by a linked list or by an array. In order to prevent clients from depending on the implementation, an ADT is often packaged as an opaque data type in one or more modules, whose interface contains only the signature (number and types of the parameters and results) of the operations. The implementation of the module—namely, the bodies of the procedures and the concrete data structure used—can then be hidden from most clients of the module. This makes it possible to change the implementation without affecting the clients. If the implementation is exposed, it is known instead as a transparent data type. When implementing an ADT, each instance (in imperative-style definitions) or each state (in functional-style definitions) is usually represented by a handle of some sort. Modern object-oriented languages, such as C++ and Java, support a form of abstract data types. When a class is used as a type, it is an abstract type that refers to a hidden representation. In this model, an ADT is typically implemented as a class, and each instance of the ADT is usually an object of that class. The module's interface typically declares the constructors as ordinary procedures, and most of the other ADT operations as methods of that class. However, such an approach does not easily encapsulate multiple representational variants found in an ADT. It also can undermine the extensibility of object-oriented programs. In a pure object-oriented program that uses interfaces as types, types refer to behaviours, not representations. Example: implementation of the abstract stack As an example, here is an implementation of the abstract stack above in the C programming language. Imperative-style interface An imperative-style interface might be: typedef struct stack_Rep stack_Rep; // type: stack instance representation (opaque record) typedef stack_Rep* stack_T; // type: handle to a stack instance (opaque pointer) typedef void* stack_Item; // type: value stored in stack instance (arbitrary address) stack_T stack_create(void); // creates a new empty stack instance void stack_push(stack_T s, stack_Item x); // adds an item at the top of the stack stack_Item stack_pop(stack_T s); // removes the top item from the stack and returns it bool stack_empty(stack_T s); // checks whether stack is empty This interface could be used in the following manner: #include <stack.h> // includes the stack interface stack_T s = stack_create(); // creates a new empty stack instance int x = 17; stack_push(s, &x); // adds the address of x at the top of the stack void* y = stack_pop(s); // removes the address of x from the stack and returns it if (stack_empty(s)) { } // does something if stack is empty This interface can be implemented in many ways. The implementation may be arbitrarily inefficient, since the formal definition of the ADT, above, does not specify how much space the stack may use, nor how long each operation should take. It also does not specify whether the stack state s continues to exist after a call x ← pop(s). In practice the formal definition should specify that the space is proportional to the number of items pushed and not yet popped; and that every one of the operations above must finish in a constant amount of time, independently of that number. To comply with these additional specifications, the implementation could use a linked list, or an array (with dynamic resizing) together with two integers (an item count and the array size). Functional-style interface Functional-style ADT definitions are more appropriate for functional programming languages, and vice versa. However, one can provide a functional-style interface even in an imperative language like C. For example: typedef struct stack_Rep stack_Rep; // type: stack state representation (opaque record) typedef stack_Rep* stack_T; // type: handle to a stack state (opaque pointer) typedef void* stack_Item; // type: value of a stack state (arbitrary address) stack_T stack_empty(void); // returns the empty stack state stack_T stack_push(stack_T s, stack_Item x); // adds an item at the top of the stack state and returns the resulting stack state stack_T stack_pop(stack_T s); // removes the top item from the stack state and returns the resulting stack state stack_Item stack_top(stack_T s); // returns the top item of the stack state ADT libraries Many modern programming languages, such as C++ and Java, come with standard libraries that implement several common ADTs, such as those listed above. Built-in abstract data types The specification of some programming languages is intentionally vague about the representation of certain built-in data types, defining only the operations that can be done on them. Therefore, those types can be viewed as "built-in ADTs". Examples are the arrays in many scripting languages, such as Awk, Lua, and Perl, which can be regarded as an implementation of the abstract list.

The American Football League (AFL) was a major professional American football league that operated for ten seasons from 1960 until 1970, when it merged with the older National Football League (NFL), and became the American Football Conference. The upstart AFL operated in direct competition with the more established NFL throughout its existence. It was more successful than earlier rivals to the NFL with the same name, the 1926, 1936 and 1940 leagues, and the later All-America Football Conference (which existed between 1944 and 1950 but only played between 1946 and 1949). This fourth version of the AFL was the most successful, created by a number of owners who had been refused NFL expansion franchises or had minor shares of NFL franchises. The AFL's original lineup consisted of an Eastern division of the New York Titans, Boston Patriots, Buffalo Bills, and the Houston Oilers, and a Western division of the Los Angeles Chargers, Denver Broncos, Oakland Raiders, and Dallas Texans. The league first gained attention by signing 75% of the NFL's first-round draft choices in 1960, including Houston's successful signing of college star and Heisman Trophy winner Billy Cannon. While the first years of the AFL saw uneven competition and low attendance, the league was buttressed by a generous television contract with the American Broadcasting Company (ABC), followed by a contract with the competing National Broadcasting Company (NBC) for games starting with the 1965 season, that broadcast the more offense-oriented football league nationwide. Continuing to attract top talent from colleges and the NFL by the mid-1960s, as well as successful franchise shifts of the Chargers from L.A. south to San Diego and the Texans north to Kansas City (becoming the Kansas City Chiefs), the AFL established a dedicated following. The transformation of the struggling Titans into the New York Jets under new ownership, including the signing of University of Alabama star quarterback Joe Namath, further solidified the league's reputation among the major media. As fierce competition made player salaries skyrocket in both leagues, especially after a series of "raids", the leagues agreed to a merger in 1966. Among the conditions were a common draft and a championship game played between the two league champions first played in early 1967, which would eventually become known as the Super Bowl. The AFL and NFL operated as separate leagues until 1970, with separate regular season and playoff schedules except for the championship game. NFL Commissioner Pete Rozelle also became chief executive of the AFL from July 26, 1966, through the completion of the merger. During this time the AFL expanded, adding the Miami Dolphins and Cincinnati Bengals. After losses by the Kansas City Chiefs and Oakland Raiders in the first two AFL-NFL World Championship Games to the Green Bay Packers (1966–67), the New York Jets and Chiefs won Super Bowls III and IV (1968–69) respectively, cementing the league's claim to being an equal to the NFL. In 1970, the AFL was absorbed into the NFL. The ten AFL franchises joined three existing NFL teams- the Baltimore Colts, the Cleveland Browns, and the Pittsburgh Steelers-to form the merged league's American Football Conference. League history During the 1950s, the National Football League had grown to rival Major League Baseball as one of the most popular professional sports leagues in the United States. One franchise that did not share in this newfound success of the league was the Chicago Cardinals – owned by the Bidwill family – who had become overshadowed by the more popular Chicago Bears. The Bidwills hoped to move their franchise, preferably to St. Louis, but could not come to terms with the league, which demanded money before it would approve the move. Needing cash, the Bidwills began entertaining offers from would-be investors, and one of the men who approached the Bidwills was Lamar Hunt, son and heir of millionaire oilman H. L. Hunt. Hunt offered to buy the Cardinals and move them to Dallas, where he had grown up. However, these negotiations came to nothing, since the Bidwills insisted on retaining a controlling interest in the franchise and were unwilling to move their team to a city where a previous NFL franchise had failed in . While Hunt negotiated with the Bidwills, similar offers were made by Bud Adams, Bob Howsam, and Max Winter. When Hunt, Adams, and Howsam were unable to secure a controlling interest in the Cardinals, they approached NFL commissioner Bert Bell and proposed the addition of expansion teams. Bell, wary of expanding the 12-team league and risking its newfound success, rejected the offer. On his return flight to Dallas, Hunt conceived the idea of an entirely new league and decided to contact the others who had shown interest in purchasing the Cardinals. In addition to Adams, Howsam, and Winter, Hunt reached out to Bill Boyer, Winter's business partner, to gauge their interest in starting a new league. Hunt's first meeting with Adams was held in March 1959. Hunt, who felt a regional rivalry would be critical for the success of the new league, convinced Adams to join and found his team in Houston. Hunt next secured an agreement from Howsam to bring a team to Denver. After Winter and Boyer agreed to start a team in Minneapolis-Saint Paul, the new league had its first four teams. Hunt then approached Willard Rhodes, who hoped to bring pro football to Seattle. However, not wanting to undermine its own brand, the University of Washington was unwilling to let the fledgling league use Husky Stadium, and Rhodes' effort came to nothing (Seattle would later get a pro football team of its own). Hunt also sought franchises in Los Angeles, Buffalo and New York City. During the summer of 1959, he sought the blessings of the NFL for his nascent league, as he did not seek a potentially costly rivalry. Within weeks of the July 1959 announcement of the league's formation, Hunt received commitments from Barron Hilton and Harry Wismer to bring teams to Los Angeles and New York, respectively. His initial efforts for Buffalo, however, were rebuffed, when Hunt's first choice of owner, Pat McGroder, declined to take part; McGroder had hoped that the threat of the AFL would be enough to prompt the NFL to expand to Buffalo. On August 14, 1959, the first league meeting was held in Chicago, and charter memberships were given to Dallas, New York, Houston, Denver, Los Angeles, and Minneapolis-Saint Paul. On August 22, the league officially was named the American Football League at a meeting in Dallas. The NFL's initial reaction was not as openly hostile as it had been with the earlier All-America Football Conference (AAFC), as Bell had even given his public approval; but he died suddenly in October 1959, and individual NFL owners soon began a campaign to undermine the new league. AFL owners were approached with promises of new NFL franchises or ownership stakes in existing ones. Only the party from Minneapolis-Saint Paul accepted, and with the addition of Ole Haugsrud and Bernie Ridder the Minnesota group joined the NFL in 1961 as the Minnesota Vikings. The older league also announced on August 29 that it had conveniently reversed its position against expansion, and planned to bring new NFL teams to Houston and Dallas, to start play in 1961. (The NFL did not expand to Houston at that time, the promised Dallas team – the Dallas Cowboys – actually started play in 1960, and the Vikings began play in 1961.) Finally, the NFL quickly came to terms with the Bidwills and allowed them to relocate the struggling Cardinals to St. Louis, eliminating that city as a potential AFL market. Ralph Wilson, who owned a minority interest in the NFL's Detroit Lions at the time, initially announced he was placing a team in Miami, but like the Seattle situation, was also rebuffed by local ownership (like Seattle, Miami would later get a pro football team of its own as well); given five other choices, Wilson negotiated with McGroder and brought the team that became the Bills to Buffalo. Buffalo was officially awarded its franchise on October 28. During a league meeting on November 22, a 10-man ownership group from Boston (led by Billy Sullivan) was awarded the AFL's eighth team. On November 30, 1959, Joe Foss, a World War II Marine fighter ace and former governor of South Dakota, was named the AFL's first commissioner. Foss commissioned a friend of Harry Wismer's to develop the AFL's eagle-on-football logo. Hunt was elected President of the AFL on January 26, 1960. The AFL draft The AFL's first draft took place the same day Boston was awarded its franchise, and lasted 33 rounds. The league held a second draft on December 2, which lasted for 20 rounds. Because the Oakland Raiders joined after the initial AFL drafts, they inherited Minnesota's selections. A special allocation draft was held in January 1960, to allow the Raiders to stock their team, as some of the other AFL teams had already signed some of Minneapolis' original draft choices. Crisis and success (1960–61) In November 1959, Minneapolis-Saint Paul owner Max Winter announced his intent to leave the AFL to accept a franchise offer from the NFL. In 1961, his team began play in the NFL as the Minnesota Vikings. Los Angeles Chargers owner Barron Hilton demanded that a replacement for Minnesota be placed in California, to reduce his team's operating costs and to create a rivalry. After a brief search, Oakland was chosen and an ownership group led by F. Wayne Valley and local real estate developer Chet Soda was formed. After initially being called the Oakland Señors, the rechristened Oakland Raiders officially joined the AFL on January 30, 1960. The AFL's first major success came when the Houston Oilers signed Billy Cannon, the All-American and 1959 Heisman Trophy winner from LSU. Cannon signed a $100,000 contract to play for the Oilers, despite having already signed a $50,000 contract with the NFL's Los Angeles Rams. The Oilers filed suit and claimed that Rams general manager Pete Rozelle had unduly manipulated Cannon. The court upheld the Houston contract, and with Cannon the Oilers appeared in the AFL's first three championship games (winning two). On June 9, 1960, the league signed a five-year television contract with ABC, which brought in revenues of approximately $2.125 million per year for the entire league. On June 17, the AFL filed an antitrust lawsuit against the NFL, which was dismissed in 1962 after a two-month trial. The AFL began regular-season play (a night game on Friday, September 9, 1960) with eight teams in the league – the Boston Patriots, Buffalo Bills, Dallas Texans, Denver Broncos, Houston Oilers, Los Angeles Chargers, New York Titans, and Oakland Raiders. Raiders' co-owner Wayne Valley dubbed the AFL ownership "The Foolish Club", a term Lamar Hunt subsequently used on team photographs he sent as Christmas gifts. The Oilers became the first-ever league champions by defeating the Chargers, 24–16, in the AFL Championship on January 1, 1961. Attendance for the 1960 season was respectable for a new league, but not nearly that of the NFL. In 1960, the NFL averaged attendance of more than 40,000 fans per game and more popular NFL teams in 1960 regularly saw attendance figures in excess of 50,000 per game, while CFL attendances averaged approximately 20,000 per game. By comparison, AFL attendance averaged about 16,500 per game and generally hovered between 10,000 and 20,000 per game. Professional football was still primarily a gate-driven business in 1960, so low attendance meant financial losses. The Raiders, with a league-worst average attendance of just 9,612, lost $500,000 in their first year and only survived after receiving a $400,000 loan from Bills owner Ralph Wilson. In an early sign of stability, however, the AFL did not lose any teams after its first year of operation. In fact, the only major change was the Chargers' move from Los Angeles to nearby San Diego (they would return to Los Angeles in 2017). On August 8, 1961, the AFL challenged the Canadian Football League to an exhibition game that would feature the Hamilton Tiger-Cats and the Buffalo Bills, which was attended by 24,376 spectators. Playing at Civic Stadium in Hamilton, Ontario, the Tiger-Cats defeated the Bills 38–21 playing a mix of AFL and CFL rules. Movement and instability (1962–63) While the Oilers found instant success in the AFL, other teams did not fare as well. The Oakland Raiders and New York Titans struggled on and off the field during their first few seasons in the league. Oakland's eight-man ownership group was reduced to just three in 1961, after heavy financial losses in their first season. Attendance for home games was poor, partly due to the team playing in the San Francisco Bay Area—which already had an established NFL team (the San Francisco 49ers)—but the product on the field was also to blame. After winning six games in their debut season, the Raiders won a total of three times in the 1961 and 1962 seasons. Oakland took part in a 1961 supplemental draft meant to boost the weaker teams in the league, but it did little good. They participated in another such draft in 1962. The Titans fared a little better on the field but had their own financial troubles. Attendance was so low for home games that team owner Harry Wismer had fans move to seats closer to the field to give the illusion of a fuller stadium on television. Eventually Wismer could no longer afford to meet his payroll, and on November 8, 1962, the AFL took over operations of the team. The Titans were sold to a five-person ownership group headed by Sonny Werblin on March 28, 1963, and in April the new owners changed the team's name to the New York Jets. The Raiders and Titans both finished last in their respective divisions in the 1962 season. The Texans and Oilers, winners of their divisions, faced each other for the 1962 AFL Championship on December 23. The Texans dethroned the two-time champion Oilers, 20–17, in a double-overtime contest that was, at the time, professional football's longest-ever game. In 1963, the Texans became the second AFL team to relocate. Lamar Hunt felt that despite winning the league championship in 1962, the Texans could not sufficiently profit in the same market as the Dallas Cowboys, which entered the NFL as an expansion franchise in 1960. After meetings with New Orleans, Atlanta, and Miami, Hunt announced on May 22 that the Texans' new home would be Kansas City, Missouri. Kansas City mayor Harold Roe Bartle (nicknamed "Chief") was instrumental in his city's success in attracting the team. Partly to honor Bartle, the franchise officially became the Kansas City Chiefs on May 26. The San Diego Chargers, under head coach Sid Gillman, won a decisive 51–10 victory over the Boston Patriots for the 1963 AFL Championship. Confident that his team was capable of beating that season's NFL champion Chicago Bears (he had the Chargers' rings inscribed with the phrase "World Champions"), Gillman approached NFL Commissioner Pete Rozelle and proposed a final championship game between the two teams. Rozelle declined the offer; however, the game would be instituted three seasons later. Watershed years (1964–65) A series of events throughout the next few years demonstrated the AFL's ability to achieve a greater level of equality with the NFL. On January 29, 1964, the AFL signed a lucrative $36 million television contract with NBC (beginning in the 1965 season), which gave the league money it needed to compete with the NFL for players. Pittsburgh Steelers owner Art Rooney was quoted as saying to NFL Commissioner Pete Rozelle after receiving the news of the AFL's new TV deal that, "They don't have to call us 'Mister' anymore". A single-game attendance record was set on November 8, 1964, when 61,929 fans packed Shea Stadium to watch the New York Jets and Buffalo Bills. The bidding war for players between the AFL and NFL escalated in 1965. The Chiefs drafted University of Kansas star Gale Sayers in the first round of the 1965 AFL draft (held November 28, 1964), while the Chicago Bears did the same in the NFL draft. Sayers eventually signed with the Bears. A similar situation occurred when the New York Jets and the NFL's St. Louis Cardinals both drafted University of Alabama quarterback Joe Namath. In what was viewed as a key victory for the AFL, Namath signed a $427,000 contract with the Jets on January 2, 1965 (the deal included a new car). It was the highest amount of money ever paid to a collegiate football player, and is cited as the strongest contributing factor to the eventual merger between the two leagues. After the 1963 season, the Newark Bears of the Atlantic Coast Football League expressed interest in joining the AFL; concerns over having to split the New York metro area with the still-uncertain Jets were a factor in the Bears' bid being rejected. In 1965, Milwaukee officials tried to lure an expansion team to play at Milwaukee County Stadium where the Green Bay Packers had played parts of their home schedule after an unsuccessful attempt to lure the Packers there full-time, but Packers head coach Vince Lombardi invoked the team's exclusive lease, and additionally, signed an extension to keep some home games in Milwaukee until 1976. In June 1965, the AFL awarded its first expansion team to Cox Broadcasting of Atlanta. The NFL quickly counteroffered insurance executive Rankin Smith a franchise, which he accepted; the Atlanta Falcons began play as an NFL franchise for the 1966 season. In March 1965, Joe Robbie had met with Commissioner Foss to inquire about an expansion franchise for Miami. On May 6, Robbie secured an agreement with Miami mayor Robert King High to bring a team to Miami. League expansion was approved at a meeting held on June 7, and on August 16 the AFL's ninth franchise was officially awarded to Robbie and entertainer Danny Thomas. The Miami Dolphins joined the league for a fee of $7.5 million and started play in the AFL's Eastern Division in 1966. The AFL also planned to add two more teams by 1967. Escalation and merger (1966–67) In 1966, the rivalry between the AFL and NFL reached an all-time peak. On April 7, Joe Foss resigned as AFL commissioner. His successor was Oakland Raiders head coach and general manager Al Davis, who had been instrumental in turning around the fortunes of that franchise. That following May, Wellington Mara, owner of the NFL's New York Giants, broke a "gentleman's agreement" against signing another league's players and lured kicker Pete Gogolak away from the AFL's Buffalo Bills. In response to the Gogolak signing and no longer content with trying to outbid the NFL for college talent, the AFL under Davis began to also recruit players already on NFL squads. Davis's strategy focused on quarterbacks in particular, and in two months he persuaded seven NFL quarterbacks to sign with the AFL. Although Davis's intention was to help the AFL win the bidding war, some AFL and NFL owners saw the escalation as detrimental to both leagues. Alarmed with the rate of spending in the league, Hilton Hotels forced Barron Hilton to relinquish his stake in the Chargers as a condition of maintaining his leadership role with the hotel chain. The same month Davis was named commissioner, several NFL owners, headed by Dallas Cowboys general manager Tex Schramm, secretly approached Lamar Hunt and other AFL owners and started negotiations with the AFL to merge. A series of secret meetings commenced in Dallas to discuss the concerns of both leagues over rapidly increasing player salaries, as well as the practice of player poaching. Hunt and Schramm completed the basic groundwork for a merger of the two leagues by the end of May, and on June 8, 1966, the merger was officially announced. Under the terms of the agreement, the two leagues would hold a common player draft. The agreement also called for a title game to be played between the champions of the respective leagues. The two leagues would be fully merged by 1970, NFL commissioner Pete Rozelle would remain as commissioner of the merged league, which would be named the NFL. Additional expansion teams would eventually be awarded by 1970 or soon thereafter to bring it to a 28-team league. (The additional expansion would not happen until 1976.) The AFL also agreed to pay indemnities of $18 million to the NFL over 20 years. In protest, Davis resigned as AFL commissioner on July 25 rather than remain until the completion of the merger, and Milt Woodard was named president of the AFL, with the "commissioner" title vacated because of Rozelle's expanded role. On January 15, 1967, the first-ever championship game between the two separate professional football leagues, the "AFL-NFL World Championship Game" (retroactively referred to as Super Bowl I), was played in Los Angeles. After a close first half, the NFL champion Green Bay Packers overwhelmed the AFL champion Kansas City Chiefs, 35–10. The loss reinforced for many the notion that the AFL was an inferior league. Packers head coach Vince Lombardi stated after the game, "I do not think they are as good as the top teams in the National Football League." The second AFL-NFL Championship (Super Bowl II) yielded a similar result. The Oakland Raiders—who had easily beaten the Houston Oilers to win their first AFL championship—were overmatched by the Packers, 33–14. The more experienced Packers capitalized on a number of Raiders miscues and never trailed. Green Bay defensive tackle Henry Jordan offered a compliment to Oakland and the AFL, when he said, "... the AFL is becoming much more sophisticated on offense. I think the league has always had good personnel, but the blocks were subtler and better conceived in this game." The AFL added its tenth and final team on May 24, 1967, when it awarded the league's second expansion franchise to an ownership group from Cincinnati, Ohio, headed by NFL legend Paul Brown. Although Brown had intended to join the NFL, he agreed to join the AFL when he learned that his team would be included in the NFL once the merger was completed. The league's last newest expansion team, the Cincinnati Bengals began play in the 1968 season, finishing last in the Western Division. Legitimacy and the end of an era (1968–1970) While many AFL players and observers believed their league was the equal of the NFL, their first two Super Bowl performances did nothing to prove it. However, on November 17, 1968, when NBC cut away from a game between the Jets and Raiders to air the children's movie Heidi, the ensuing uproar helped disprove the notion that fans still considered the AFL an inferior product. The perception of AFL inferiority forever changed on January 12, 1969, when the AFL Champion New York Jets shocked the heavily favored NFL Champion Baltimore Colts in Super Bowl III. The Colts, who entered the contest favored by as many as 18 points, had completed the 1968 NFL season with a 13–1 record, and won the NFL title with a convincing 34–0 win over the Cleveland Browns. Led by their stalwart defense—which allowed a record-low 144 points—the 1968 Colts were considered one of the best-ever NFL teams. By contrast, the Jets had allowed 280 points, the highest total for any division winner in the two leagues. They had also only narrowly beaten the favored Oakland Raiders 27–23 in the AFL championship game. Jets quarterback Joe Namath recalled that in the days leading up to the game, he grew increasingly angry when told New York had no chance to beat Baltimore. Three days before the game, a frustrated Namath responded to a heckler at the Touchdown Club in Miami by declaring, "We're going to win Sunday, I guarantee it!" Namath and the Jets made good on his guarantee as they held the Colts scoreless until late in the fourth quarter. The Jets won, 16–7, in what is considered one of the greatest upsets in American sports history. With the win, the AFL finally achieved parity with the NFL and legitimized the merger of the two leagues. That notion was reinforced one year later in Super Bowl IV, when the AFL champion Kansas City Chiefs upset the NFL champion Minnesota Vikings, 23–7, in the last championship game to be played between the two leagues. The Vikings, favored by 12½ points, were held to just 67 rushing yards. The last game in AFL history was the AFL All-Star Game, held in Houston's Astrodome on January 17, 1970. The Western All-Stars, led by Chargers quarterback John Hadl, defeated the Eastern All-Stars, 26–3. Buffalo rookie running back O. J. Simpson carried the ball for the last play in AFL history. Hadl was named the game's Most Valuable Player. The AFL ceased to exist as an unincorporated organization on February 1, 1970, when the NFL granted 10 new franchises and issued a new constitution. Prior to the start of the 1970 NFL season, the merged league was organized into two conferences of three divisions each. All ten AFL teams made up the bulk of the new American Football Conference. To avoid having an inequitable number of teams in each conference, the leagues voted to move three NFL teams to the AFC. Motivated by the prospect of an intrastate rivalry with the Bengals as well as by personal animosity toward Paul Brown, Cleveland Browns owner Art Modell quickly offered to include his team in the AFC. He helped persuade the Pittsburgh Steelers (the Browns' archrivals) and Baltimore Colts (who shared the Baltimore-Washington market with the Washington Redskins) to follow suit, and each team received US$3 million to make the switch. The remaining 13 NFL teams became part of the National Football Conference. Pro Football Hall of Fame receiver Charlie Joiner, who started his career with the Houston Oilers (1969), was the last AFL player active in professional football, retiring after the 1986 season, when he played for the San Diego Chargers. Legacy Overview The American Football League stands as the only professional football league to successfully compete against the NFL. When the two leagues merged in 1970, all ten AFL franchises and their statistics became part of the new NFL. Every other professional league that had competed against the NFL before the AFL–NFL merger had folded completely: the three previous leagues named "American Football League" and the All-America Football Conference. From an earlier AFL (1936–1937), only the Cleveland Rams (now the Los Angeles Rams) joined the NFL and are currently operating, as are the Cleveland Browns and the San Francisco 49ers from the AAFC. A third AAFC team, the Baltimore Colts (not related to the 1953–1983 Baltimore Colts or to the current Indianapolis Colts franchise), played only one year in the NFL, disbanding at the end of the 1950 season. The league resulting from the merger was a 26-team juggernaut (since expanded to 32) with television rights covering all of the Big Three television networks (and since the 1990s, the newer Fox network) and teams in close proximity to almost all of the top 40 metropolitan areas, a fact that has precluded any other competing league from gaining traction since the merger; failed attempts to mimic the AFL's success included the World Football League (1974–75), United States Football League (1983–85), the United Football League (2009–2012) and the AAF (2019), and two iterations of the XFL (2001 and 2020), in addition to the NFL-backed and created World League of American Football (1991-92). The AFL was also the most successful of numerous upstart leagues of the 1960s and 1970s that attempted to challenge a major professional league's dominance. All nine teams that were in the AFL at the time the merger was agreed upon were accepted into the league intact (as was the tenth team added between the time of the merger's agreement and finalization), and none of the AFL's teams have ever folded. For comparison, the World Hockey Association (1972–79) managed to have four of its six remaining teams merged into the National Hockey League, which actually caused the older league to contract a franchise, but WHA teams were forced to disperse the majority of their rosters and restart as expansion teams. The merged WHA teams were also not financially sound (in large part from the hefty expansion fees the NHL imposed on them), and three of the four were forced to relocate within 20 years. Like the WHA, The American Basketball Association (1967–76) also managed to have only four of its teams merged into the National Basketball Association, and the rest of the league was forced to fold. Both the WHA and ABA lost several teams to financial insolvency over the course of their existences. The Continental League, a proposed third league for Major League Baseball that was to begin play in 1961, never played a single game, largely because MLB responded to the proposal by expanding to four of that league's proposed cities. Historically, the only other professional sports league in the United States to exhibit a comparable level of franchise stability from its inception was the American League of Major League Baseball, which made its debut in the early 20th century. Rule changes The NFL adopted some of the innovations introduced by the AFL immediately and a few others in the years following the merger. One was including the names on player jerseys. The older league also adopted the practice of using the stadium scoreboard clocks to keep track of the official game time, instead of just having a stopwatch used by the referee. The AFL played a 14-game schedule for its entire existence, starting in 1960. The NFL, which had played a 12-game schedule since 1947, changed to a 14-game schedule in 1961, a year after the American Football League instituted it. The AFL also introduced the two-point conversion to professional football 34 years before the NFL instituted it in 1994 (college football had adopted the two-point conversion in the late 1950s). All of these innovations pioneered by the AFL, including its more exciting style of play and colorful uniforms, have essentially made today's professional football more like the AFL than like the old-line NFL. The AFL's challenge to the NFL also laid the groundwork for the Super Bowl, which has become the standard for championship contests in the United States of America. Television The NFL also adapted how the AFL used the growing power of televised football games, which were bolstered with the help of major network contracts (first with ABC and later with NBC). With that first contract with ABC, the AFL adopted the first-ever cooperative television plan for professional football, in which the proceeds were divided equally among member clubs. It featured many outstanding games, such as the classic 1962 double-overtime American Football League championship game between the Dallas Texans and the defending champion Houston Oilers. At the time it was the longest professional football championship game ever played. The AFL also appealed to fans by offering a flashier style of play (just like the ABA in basketball), compared to the more conservative game of the NFL. Long passes ("bombs") were commonplace in AFL offenses, led by such talented quarterbacks as John Hadl, Daryle Lamonica and Len Dawson. Despite having a national television contract, the AFL often found itself trying to gain a foothold, only to come up against roadblocks. For example, CBS-TV, which broadcast NFL games, ignored and did not report scores from the innovative AFL, on orders from the NFL. It was only after the merger agreement was announced that CBS began to give out AFL scores. Expanding and reintroducing the sport to more cities The AFL took advantage of the burgeoning popularity of football by locating teams in major cities that lacked NFL franchises. Hunt's vision not only brought a new professional football league to California and New York, but introduced the sport to Colorado, restored it to Texas and later to fast-growing Florida, as well as bringing it to Greater Boston for the first time in 12 years. Buffalo, having lost its original NFL franchise in 1929 and turned down by the NFL at least twice (1940 and 1950) for a replacement, returned to the NFL with the merger. The return of football to Kansas City was the first time that city had seen professional football since the NFL's Kansas City Blues of the 1920s; the arrival of the Chiefs, and the contemporary arrival of the St. Louis Football Cardinals, brought professional football back to Missouri for the first time since the temporary St. Louis Gunners of 1934. St. Louis would later regain an NFL franchise in 1995 with the relocation of the LA Rams to the city. The Rams moved back in 2016. In the case of the Dallas Cowboys, the NFL had long sought to return to the Dallas area after the Dallas Texans folded in 1952, but was originally met with strong opposition by Washington Redskins owner George Preston Marshall, who had enjoyed a monopoly as the only NFL team to represent the American South. Marshall later changed his position after future-Cowboys owner Clint Murchison bought the rights to Washington's fight song "Hail to the Redskins" and threatened to prevent Marshall from playing it at games. By then, the NFL wanted to quickly award the new Dallas franchise to Murchison so the team could immediately begin play and compete with the AFL's Texans. As a result, the Cowboys played its inaugural season in 1960 without the benefit of the NFL draft. The Texans eventually ceded Dallas to the Cowboys and became the Kansas City Chiefs. As part of the merger agreement, additional expansion teams would be awarded by 1970 or soon thereafter to bring the league to 28 franchises; this requirement was fulfilled when the Seattle Seahawks and the Tampa Bay Buccaneers began play in 1976. In addition, had it not been for the existence of the Oilers from 1960 to 1996, the Houston Texans also would likely not exist today; the 2002 expansion team restored professional football in Houston after the original charter AFL member Oilers relocated to become the Tennessee Titans. Kevin Sherrington of The Dallas Morning News has argued that the presence of AFL and the subsequent merger radically altered the fortunes of the Pittsburgh Steelers, saving the team "from stinking". Before the merger, the Steelers had long been one of the NFL's worst teams. Constantly lacking the money to build a quality team, the Steelers had only posted eight winning seasons, and just one playoff appearance, since their first year of existence in 1933 until the end of the 1969 season. They also finished with a 1–13 record in 1969, tied with the Chicago Bears for the worst record in the NFL. The $3 million indemnity that the Steelers received for joining the AFC with the rest of the former AFL teams after the merger helped them rebuild into a contender, drafting eventual-Pro Football Hall of Famers like Terry Bradshaw and Joe Greene, and ultimately winning four Super Bowls in the 1970s. Since the 1970 merger, the Steelers have the NFL's highest winning percentage, the most total victories, the most trips to either conference championship game, are tied for the second most trips to the Super Bowl (tied with the Dallas Cowboys and Denver Broncos, trailing only the New England Patriots), and have won six Super Bowl championships, tied with the Patriots for the most in NFL history. Effects on players Perhaps the greatest social legacy of the AFL was the domino effect of its policy of being more liberal than the entrenched NFL in offering opportunity for black players. While the NFL was still emerging from thirty years of segregation influenced by Washington Redskins' owner George Preston Marshall, the AFL actively recruited from small and predominantly black colleges. The AFL's color-blindness led not only to the explosion of black talent on the field, but to the eventual entry of blacks into scouting, coordinating, and ultimately head coaching positions, long after the league merged itself out of existence. The AFL's free agents came from several sources. Some were players who could not find success playing in the NFL, while another source was the then newly-formed Canadian Football League. In the late 1950s, many players released by the NFL, or un-drafted and unsigned out of college by the NFL, went North to try their luck with the CFL (which formed in 1958), and later returned to the states to play in the AFL. In the league's first years, players such as Oilers' George Blanda, Chargers/Bills' Jack Kemp, Texans' Len Dawson, the NY Titans' Don Maynard, Raiders/Patriots/Jets' Babe Parilli, Pats' Bob Dee proved to be AFL standouts. Other players such as the Broncos' Frank Tripucka, the Pats' Gino Cappelletti, the Bills' Cookie Gilchrist and the Chargers' Tobin Rote, Sam DeLuca and Dave Kocourek also made their mark to give the fledgling league badly needed credibility. Rounding out this mix of potential talent were the true "free agents", the walk-ons and the "wanna-be's", who tried out in droves for the chance to play professional American football. After the AFL–NFL merger agreement in 1966, and after the AFL's Jets defeated an extremely strong Baltimore Colts team, a popular misconception fostered by the NFL and spread by media reports was that the AFL defeated the NFL because of the Common Draft instituted in 1967. This apparently was meant to assert that the AFL could not achieve parity as long as it had to compete with the NFL in the draft. But the 1968 Jets had less than a handful of "common draftees". Their stars were honed in the AFL, many of them since the Titans days. Players who chose the AFL to develop their talent included Lance Alworth and Ron Mix of the Chargers, who had also been drafted by the NFL's San Francisco 49ers and Baltimore Colts respectively. Both eventually were elected to the Pro Football Hall of Fame after earning recognition during their careers as being among the best at their positions. Among specific teams, the 1964 Buffalo Bills stood out by holding their opponents to a pro football record 913 yards rushing on 300 attempts, while also recording fifty quarterback sacks in a 14-game schedule. In 2009, a five-part series, Full Color Football: The History of the American Football League, on the Showtime Network, refuted many of the long-held misconceptions about the AFL. In it, Abner Haynes tells of how his father forbade him to accept being drafted by the NFL, after drunken scouts from that league had visited the Haynes home; the NFL Cowboys' Tex Schramm is quoted as saying that if his team had ever agreed to play the AFL's Dallas Texans, they would very likely have lost; George Blanda makes a case for more AFL players being inducted to the Pro Football Hall of Fame by pointing out that Hall of Famer Willie Brown was cut by the Houston Oilers because he couldn't cover Oilers flanker Charlie Hennigan in practice. Later, when Brown was with the Broncos, Hennigan needed nine catches in one game against the Broncos to break Lionel Taylor's Professional Football record of 100 catches in one season. Hennigan caught the nine passes and broke the record, even though he was covered by Brown. Influence on professional football coaching The AFL also spawned coaches whose style and techniques have profoundly affected the play of professional football to this day. In addition to AFL greats like Hank Stram, Lou Saban, Sid Gillman and Al Davis were eventual hall of fame coaches such as Bill Walsh, a protégé of Davis with the AFL Oakland Raiders for one season; and Chuck Noll, who worked for Gillman and the AFL LA/San Diego Chargers from 1960 through 1965. Others include Buddy Ryan (AFL's New York Jets), Chuck Knox (Jets), Walt Michaels (Jets), and John Madden (AFL's Oakland Raiders). Additionally, many prominent coaches began their pro football careers as players in the AFL, including Sam Wyche (Cincinnati Bengals), Marty Schottenheimer (Buffalo Bills), Wayne Fontes (Jets), and two-time Super Bowl winner Tom Flores (Oakland Raiders). Flores also has a Super Bowl ring as a player (1969 Kansas City Chiefs). AFL 50th Anniversary Celebration As the influence of the AFL continues through the present, the 50th anniversary of its launch was celebrated during 2009. The season-long celebration began in August with the 2009 Pro Football Hall of Fame Game in Canton, Ohio, between two AFC teams (as opposed to the AFC-vs-NFC format the game first adopted in 1971). The opponents were two of the original AFL franchises, the Buffalo Bills and Tennessee Titans (the former Houston Oilers). Bills' owner Ralph C. Wilson Jr. (a 2009 Hall of Fame inductee) and Titans' owner Bud Adams were the only surviving members of the Foolish Club at the time (both are now deceased; Wilson's estate sold the team in 2014), the eight original owners of AFL franchises. (As of the season, the Titans and Chiefs are still owned by descendants of the original eight owners.) The Hall of Fame Game was the first of several "Legacy Weekends", during which each of the "original eight" AFL teams sported uniforms from their AFL era. Each of the 8 teams took part in at least two such "legacy" games. On-field officials also wore red-and-white-striped AFL uniforms during these games. In the fall of 2009, the Showtime pay-cable network premiered Full Color Football: The History of the American Football League, a 5-part documentary series produced by NFL Films that features vintage game film and interviews as well as more recent interviews with those associated with the AFL. The NFL sanctioned a variety of "Legacy" gear to celebrate the AFL anniversary, such as "throwback" jerseys, T-shirts, signs, pennants and banners, including items with the logos and colors of the Dallas Texans, Houston Oilers, and New York Titans, the three of the Original Eight AFL teams which have changed names or venues. A December 5, 2009, story by Ken Belson in The New York Times quotes league officials as stating that AFL "Legacy" gear made up twenty to thirty percent of the league's annual $3 billion merchandise income. Fan favorites were the Denver Broncos' vertically striped socks, which could not be re-stocked quickly enough. AFL franchises Today, two of the NFL's eight divisions are composed entirely of former AFL teams, the AFC West (Broncos, Chargers, Chiefs, and Raiders) and the AFC East (Bills, Dolphins, Jets, and Patriots). Additionally, the Bengals now play in the AFC North and the Tennessee Titans (formerly the Oilers) play in the AFC South. Former stadiums: Oakland–Alameda County Coliseum, Los Angeles Memorial Coliseum, Fenway Park, Nickerson Field, Alumni Stadium, Nippert Stadium, the Cotton Bowl, Balboa Stadium and Kezar Stadium), still standing but currently vacant (Houston Astrodome), or demolished. AFL playoffs From 1960 to 1968, the AFL determined its champion via a single-elimination playoff game between the winners of its two divisions. The home teams alternated each year by division, so in 1968 the Jets hosted the Raiders, even though Oakland had a better record (this was changed in 1969). In 1963, the Buffalo Bills and Boston Patriots finished tied with identical records of 7–6–1 in the AFL East Division. There was no tie-breaker protocol in place, so a one-game playoff was held in War Memorial Stadium in December. The visiting Patriots defeated the host Bills 26–8. The Patriots traveled to San Diego as the Chargers completed a three-game season sweep over the weary Patriots with a 51–10 victory. A similar situation occurred in the 1968 season, when the Oakland Raiders and the Kansas City Chiefs finished the regular season tied with identical records of 12–2 in the AFL West Division. The Raiders beat the Chiefs 41–6 in a division playoff to qualify for the AFL Championship Game. In 1969, the final year of the independent AFL, Professional Football's first "wild card" playoffs were conducted. A four-team playoff was held, with the second-place teams in each division playing the winner of the other division. The Chiefs upset the Raiders in Oakland 17–7 in the league's Championship, the final AFL game played. The Kansas City Chiefs were the first Super Bowl champion to win two road playoff games and the first wildcard team to win the Super Bowl, although the term "wildcard" was coined by the media, and not used officially until several years later. AFL Championship Games AFL All-Star games The AFL did not play an All-Star game after its first season in 1960, but did stage All-Star games for the 1961 through 1969 seasons. All-Star teams from the Eastern and Western divisions played each other after every season except 1965. That season, the league champion Buffalo Bills played all-stars from the other teams. After the 1964 season, the AFL All-Star game had been scheduled for early 1965 in New Orleans' Tulane Stadium. After numerous black players were refused service by a number of area hotels and businesses, black and white players alike called for a boycott. Led by Bills players such as Cookie Gilchrist, the players successfully lobbied to have the game moved to Houston's Jeppesen Stadium.

Associazione Sportiva Roma (Rome Sport Association), commonly referred to as Roma (), is a professional football club based in Rome, Italy. Founded by a merger in 1927, Roma has participated in the top tier of Italian football for all of its existence, except for the 1951–52 season. Roma has won Serie A three times, in 1941–42, 1982–83 and 2000–01, as well as nine titles and two titles. In European competitions, Roma won the Inter-Cities Fairs Cup in 1960–61 and the UEFA Europa Conference League in 2021–22, while they finished runners-up in the 1983–84 European Cup, the 1990–91 UEFA Cup and the 2022–23 UEFA Europa League. Sixteen players have won the FIFA World Cup while playing at Roma: Attilio Ferraris and Enrique Guaita (1934); Guido Masetti and Eraldo Monzeglio (1934 and 1938); Aldo Donati and Pietro Serantoni (1938); Bruno Conti (1982); Rudi Völler and Thomas Berthold (1990); Aldair (1994); Vincent Candela (1998); Cafu (2002); Daniele De Rossi, Simone Perrotta and Francesco Totti (2006); Paulo Dybala (2022). Since 1953, Roma has played home matches at the Stadio Olimpico, a venue the club shares with city rivals Lazio. With a capacity of over 72,000, the stadium is the second-largest of its kind in Italy, with only the San Siro able to seat more. The club plans to move to a new stadium, though it is yet to start construction. Having a strong local rivalry, Roma and Lazio contest the Derby della Capitale. The club's home colours are carmine red and golden yellow, which gives Roma its nickname "I Giallorossi" ("The Yellow and Reds"). These colours have often been combined with white shorts. The club badge features a she-wolf, an allusion to the founding myth of Rome. History Foundation AS Roma was founded in the spring of 1927 when Italo Foschi initiated the merger of three older Italian Football Championship clubs from the city of Rome: Roman FC, SS Alba-Audace and Fortitudo-Pro Roma SGS. Foschi was an important Roman representative of the ruling National Fascist Party. The purpose of the merger was to give the Italian capital a strong club to rival that of the more dominant Northern Italian clubs of the time. The only major Roman club to resist the merger was Lazio because of the intervention of the army General Vaccaro, a member of the club and executive of Italian Football Federation (FIGC). All three founding clubs were relegated, but the fascist-aligned FIGC bet over the capacity of the new team to give a stronger representation to the capital of Italy, and they were awarded a wild card for the , the Serie A forerunner. The club played its earliest seasons at the Motovelodromo Appio stadium, before settling in the working-class streets of Testaccio, where it built an all-wooden ground Campo Testaccio; this was opened in November 1929. An early season in which Roma made a large mark was the 1930–31 championship, where the club finished as runners-up behind . Captain Attilio Ferraris, along with Guido Masetti, Fulvio Bernardini and Rodolfo Volk, were highly important players during this period. First title victory and decline After a slump in league form and the departure of high key players, Roma eventually rebuilt their squad, adding goalscorers such as the Argentine Enrique Guaita. Under the management of Luigi Barbesino, the Roman club came close to their first title in 1935–36, finishing just one point behind champions Bologna. Roma returned to form after being inconsistent for much of the late 1930s. Roma recorded an unexpected title triumph in the 1941–42 season by winning their first title. The 18 goals scored by local player Amedeo Amadei were essential to the Alfréd Schaffer-coached Roma side winning the title. At the time, Italy was involved in World War II and Roma were playing at the Stadio Nazionale PNF. In the years just after the war, Roma were unable to recapture their league stature from the early 1940s. Roma finished in the lower half of Serie A for five seasons in a row, before eventually succumbing to their only ever relegation to Serie B at the end of the 1950–51 season, around a decade after their championship victory. Under future Italy national team manager Giuseppe Viani, promotion straight back up was achieved. After returning to the Serie A, Roma managed to stabilise themselves as a top-half club again with players such as Egisto Pandolfini, Dino da Costa and Dane Helge Bronée. Their best finish of this period was under the management of Englishman Jesse Carver, when in 1954–55, they finished as runners-up after Udinese, who originally finished second, were relegated for corruption. Although Roma were unable to break into the top four during the following decade, they did achieve some measure of cup success. Their first honour outside of Italy was recorded in 1960–61 when Roma won the Inter-Cities Fairs Cup by defeating Birmingham City 4–2 in the finals. A few years later, Roma won their first Coppa Italia trophy in 1963–64 after defeating Torino 1–0. Their lowest point came during the 1964–65 season, when manager Juan Carlos Lorenzo announced the club could not pay its players and was unlikely to be able to afford to travel to Vicenza to fulfil its next fixture. Supporters kept the club going with a fundraiser at the Sistine Theatre and bankruptcy was avoided with the election of a new club president Franco Evangelisti. Their second Coppa Italia trophy was won in 1968–69, when it competed in a small, league-like system. Giacomo Losi set a Roma appearance record in 1969 with 450 appearances in all competitions, a record that would last 38 years. Time of mixed fortunes from the 1970s to the 1990s Roma were able to add another cup to their collection in 1972, with a 3–1 victory over Blackpool in the Anglo-Italian Cup. During much of the 1970s, Roma's appearance in the top half of Serie A was sporadic. The best place the club were able to achieve during the decade was third in 1974–75. Notable players who turned out for the club during this period included midfielders Giancarlo De Sisti and Francesco Rocca. The dawning of a newly successful era in Roma's footballing history was brought in with another Coppa Italia victory; they defeated Torino on penalties to win the 1979–80 edition. Roma would reach heights in the league which they had not touched since the 1940s by narrowly and controversially finishing as runners-up to in 1980–81. Former Milan player Nils Liedholm was the manager at the time, with players such as Bruno Conti, Agostino Di Bartolomei, Roberto Pruzzo and Falcão. The second scudetto did not elude Roma for much longer. In 1982–83, the Roman club won the title for the first time in 41 years, amidst celebrations in the capital. The following season, Roma finished as runners-up in Italy and collected a Coppa Italia title; they also finished as runners-up in the European Cup final of 1984. The European Cup final with Liverpool ended in a 1–1 draw with a goal from Pruzzo, but Roma eventually lost in the penalty shoot-out. Roma's successful run in the 1980s would finish with a runners-up spot in 1985–86 and a Coppa Italia victory, beating out Sampdoria 3–2. After, a comparative decline began in the league, one of the few league highs from the following period being a third-place finish in 1987–88. At the start of the 1990s, the club was involved in an all-Italian UEFA Cup final, where they lost 2–1 to in 1991. The same season, the club won its seventh Coppa Italia and ended runners-up to Sampdoria in the Supercoppa Italiana. Aside from finishing runners-up to Torino in a Coppa Italia final, the rest of the decade was largely sub-par in the history of Roma, particularly in the league, where the highest they could manage was fourth in 1997–98. The early 1990s also saw the emergence of homegrown striker Francesco Totti, who would go on to be an important member of the team and the club's iconic captain. Third scudetto in the Sensi era Roma won their third Serie A title in 2000–01. The Scudetto was won on the last day of the season after defeating Parma 3–1, edging Juventus by two points. The club's captain, Francesco Totti, was a large reason for the title victory and he would become one of the main heroes in the club's history, going on to break several club records. Other important players during this period included: Aldair, Cafu, Gabriel Batistuta and Vincenzo Montella. In the 2001–02 Serie A, Roma ended as runners-up to Juventus by one point. This would be the start of Roma finishing as runners-up several times in both Serie A and Coppa Italia during the 2000s – they lost out 4–2 to Milan in the Coppa Italia final of 2003 and lost to Milan again by finishing second in Serie A for the 2003–04 season. The club also re-capitalized several time in 2003–04 season. In November 2003, €37.5 million was injected by "Roma 2000" to cover the half-year loss and loss carried from previous year. and again on 30 June for €44.57 million. Through stock market, a further €19.850 million of new shares issued, and at the year end, the share capital was €19.878 million, which was unchanged . The following season also saw the departure of Walter Samuel for €25 million and Emerson for €28 million, which decreased the strength of the squad. The Giallorossi finished in eighth place, one of the worst of recent seasons. On 9 July 2006, Roma's Francesco Totti, Daniele De Rossi and Simone Perrotta were part of the Italy national team which defeated France in the 2006 FIFA World Cup Final. In the Calciopoli scandal of 2006, Roma were not one of the teams involved. After punishments were issued, Roma was re-classified as runners-up for 2005–06, the same season they finished second in the Coppa Italia losing to Internazionale. In the two following seasons, 2006–07 and 2007–08, Roma finished as Serie A runners-up, meaning that in the 2000s, Roma finished in the top two positions more than any other decade in their history. Meanwhile, in the UEFA Champions League during both of these seasons, they reached the quarter-finals before going out to Manchester United. In the 2008–09 Champions League, Roma reached the knockout stage ahead of Chelsea in their group, thus finishing for the first time in their history as winners of the group stage. However, they lost to Arsenal in the knockout stage on penalty kicks. After a disappointing start to the 2009–10 season, Claudio Ranieri replaced Luciano Spalletti as head coach. At the time of the switch, Roma lay bottom of the Serie A table after losses to Juventus and Genoa. Despite this setback, Roma went on unbeaten streak of 24 matches in the league – with the last of the 24 being a 2–1 win over rivals Lazio, whereby they came from 1–0 down at half-time to defeat their city rivals after Ranieri substituted both Totti and De Rossi at the interval. The Giallorossi were on top of the table at one point, before a loss to Sampdoria later in the season. Roma would finish runners-up to Internazionale yet again in both Serie A and the Coppa Italia. During the 2000s, Roma had finally recaptured the Scudetto, two Coppa Italia trophies, and their first two Supercoppa Italiana titles. Other notable contributions to the club's history have included a return to the Champions League quarter-finals (in the 2006–07 and 2007–08 editions) since 1984, six runners up positions in the league, four Coppa Italia finals and three Supercoppa finals – marking Roma's greatest ever decade. American ownership and Pallotta era In the summer of 2010, the Sensi family agreed to relinquish their control of Roma as part of a debt-settlement agreement, ending their reign that had begun in 1993. Until a new owner was appointed, Rosella Sensi continued her directorial role of the club. Following a series of poor results that saw Roma engage in a winless streak of five consecutive matches, Claudio Ranieri resigned as head coach in February 2011, and former striker Vincenzo Montella was appointed as caretaker manager until the end of the season. It was also during this season that Roma icon Francesco Totti scored his 200th Serie A goal against Fiorentina in March 2011, becoming only the sixth player to achieve such a feat. On 16 April 2011, the takeover contract was closed with an American investment group led by Thomas R. DiBenedetto, with James Pallotta, Michael Ruane and Richard D'Amore as partners. DiBenedetto became the 22nd president of the club, serving from 27 September 2011 to 27 August 2012 and was succeeded by Pallotta. The new intermediate holding company, NEEP Roma Holding, was 60% owned by American's "AS Roma SPV, LLC" and the rest (40%) was retained by the creditor of Sensi, UniCredit. In turn, NEEP owned all shares held previously by Sensi (about 67%) with the rest free float in the stock market. UniCredit later disinvested NEEP Roma Holding to sell to "AS Roma SPV, LLC" and Pallotta. The new ownership hired Walter Sabatini as director of football and former Spanish international and Barcelona B coach Luis Enrique as manager. Signings included attacking midfielder Erik Lamela from River Plate and forward Bojan from Barcelona, as well as Dani Osvaldo and Miralem Pjanić. On the pitch, the team were eliminated from 2011–12 UEFA Europa League play-off round by Slovan Bratislava. In 2012, Pallotta became the new president. The 2012–13 pre-season started with the hiring of former manager Zdeněk Zeman. He was sacked on 2 February 2013, while the team ended up in sixth place in Serie A, and lost 1–0 to rivals Lazio in the Coppa Italia final. It was the first time that Lazio and Roma clashed in the Coppa Italia final. As a result, Roma missed out on European competition for the second-straight season. On 12 June 2013, Rudi Garcia was appointed the new manager of Roma. He won his first ten matches (an all-time Serie A record) including a 2–0 derby win against Lazio, a 3–0 victory away to Internazionale and a 2–0 home win over title rivals Napoli. During this run, Roma scored 24 times while conceding just once, away to Parma. The club earned 85 points and finished second to Juventus, who won the league with a record-breaking 102 points. In 2014–15, Roma finished second behind Juventus for the second consecutive season after a poor run of form in 2015. At the end of season, the club was sanctioned for loss making and breaking UEFA Financial Fair Play Regulations, being punished with a fine of up to €6 million and a limited squad for UEFA competitions. Ahead of the 2015–16 season, Roma acquired Bosnia international, Edin Džeko, from Manchester City on a €4 million loan with an €11 million option to buy clause, which was activated. On 13 January 2016, Garcia was sacked after a run of one win in seven Serie A matches. Luciano Spalletti was subsequently appointed manager of Roma for his second spell. On 21 February, Totti publicly criticised Spalletti due to his own lack of playing-time since returning from injury. Consequently, Totti was subsequently dropped by Spalletti for Roma's 5–0 win over Palermo, with the decision causing an uproar among the fans and in the media. After their initial disagreements, Spalletti began to use Totti as an immediate impact substitute, and he contributed with four goals and one assist after coming off the bench in five consecutive Serie A matches. Spalletti was able to lead Roma from a mid-table spot to a third-place finish in Serie A, clinching the UEFA Champions League play-off spot. During the summer of 2016, Roma lost midfielder Miralem Pjanić to rivals Juventus to improve its financial position. On 27 April 2017, Roma appointed sporting director Monchi, formerly of Sevilla FC. On 28 May that year, on the last day of the 2016–17 season, Totti made his 786th and final appearance for Roma before retiring in a 3–2 home win against Genoa, coming on as a substitute for Mohamed Salah in the 54th minute and received a standing ovation from the fans. The win saw Roma finish second in Serie A behind Juventus. Daniele De Rossi succeeded Totti as club captain and signed a new two-year contract. On 13 June 2017, former Roma player Eusebio Di Francesco was appointed as the club's new manager, replacing Spalletti, who had left for Internazionale. Roma again lost a key player during the summer transfer window, with Mohamed Salah joining Liverpool F.C. for a fee of €39 million (£34m). Several new players joined the club, including a club-record deal of up to €40 million for Sampdoria striker Patrik Schick. In the 2017–18 UEFA Champions League Roma were drawn against FC Barcelona in the quarter-finals, being defeated 4–1 away in the first leg but winning 3–0 in the second to advance on away goals to the semi-finals for the first time since 1984. Roma then lost to Liverpool, the team that had defeated them in the 1984 European Cup Final 7–6 on aggregate. Roma ended the 2017–18 season in 3rd place on 77 points, qualifying for the following season's Champions League. In the summer of 2018, Roma were busy in the transfer market, in large parts thanks to the €83 million they received from reaching the Champions League semi-finals, as well as selling goalkeeper Alisson for a world record €72 million including bonuses to Liverpool. Roma spent €150 million to sign the likes of Shick, Nzonzi, Pastore, Kluivert, Defrel and more, while selling their two starting midfielders from the previous season, Nainggolan and Strootman. The 2018-19 season saw the club eliminated against Porto 4–3 on aggregate in the Champions League round of 16; Di Francesco was sacked and replaced by Claudio Ranieri who served as caretaker manager. The following day, sporting director Monchi stepped down due to disagreements with Pallotta; the club president disputed his account In Monchi's two years at the club, he spent £208 million on 21 signings, while when he left, 12 of his signings remained at the club. Under Ranieri, Roma failed to qualify for the Champions League, finishing 6th. Friedkin era and European success In December 2019, AS Roma SPV LLC was in final negotiations to sell the team for $872 million, to American businessman Dan Friedkin, however negotiations stalled during the COVID-19 pandemic. On 6 August 2020, Friedkin signed the preliminary contract to agree to pay $591 million to Pallotta, the main shareholder of Roma. Paulo Fonseca, who was hired as manager in 2019, left two years later and was replaced by fellow Portuguese José Mourinho. On 25 May 2022, he led Roma to win the inaugural edition of UEFA Europa Conference League, defeating Feyenoord in the final. Club identity Roma's colours of carmine red with a golden yellow trim represents the traditional colours of Rome, the official seal of the Comune di Roma features the same colours. The gold and the purple-red represent Roman imperial dignity. White shorts and black socks are usually worn with the red shirt. However, in particularly high key matches, the shorts and socks are the same colour as the home shirt. The kit itself was originally worn by Roman Football Club; one of the three clubs who merged to form the current incarnation in 1927. Because of the colours they wear, Roma are often nicknamed i giallorossi meaning the yellow-reds. Roma's away kit is traditionally white, with a third kit changing colour from time to time. A popular nickname for the club is "i lupi" ("the wolves") – the animal has always featured on the club's badge in different forms throughout their history. The emblem of the team is currently the one which was used when the club was first founded. It portrays the female wolf with the two infant brothers Romulus and Remus, illustrating the myth of the founding of Rome, superimposed on a bipartite golden yellow over a maroon red shield. In the myth from which the club takes their nickname and logo, the twins (sons of Mars and Rhea Silvia) are thrown into the river Tiber by their uncle Amulius. A she-wolf then saved the twins and looked after them. Eventually, the two twins took revenge on Amulius before falling out themselves – Romulus killed Remus and was thus made king of a new city named in his honour, Rome. Kit suppliers and shirt sponsors Facilities Stadiums The first sport facility Roma used was the Motovelodromo Appio, previously used by Alba-Audace. Roma only played the 1927–28 season there until they moved to Campo Testaccio the very next season. Campo Testaccio was used through 1929 to 1940. The team moved later to the Stadio Nazionale del PNF, where they spent 13 years before moving once again. In the 1953–54 season, Roma moved to the Olympic arena, Stadio Olimpico, which it shares with Lazio. The arena has undergone several changes over the years. The most significant change took place in the nineties when Stadio Olimpico was demolished and then reconstructed for the 1990 FIFA World Cup, held in Italy. Roma have played almost every season since 1953–54, with exception of the 1989–90 seasons due to the reconstruction of Stadio Olimpico. That year, Roma played its home matches at Stadio Flaminio. On 30 December 2012, Roma club president James Pallotta announced the construction of a new stadium in the Tor di Valle area of Rome. The new stadium, Stadio della Roma, will have a capacity of 52,500 spectators. On 2 February 2017, the Region of Lazio and the mayor of Rome rejected the proposal to build a new stadium. However, it was later approved on 24 February after final review of the stadium's design adjustments. In August 2017, the stadium suffered another delay, forcing Roma to renew their lease with the Stadio Olimpico until 2020. It is presently uncertain when the stadium will open. On 5 December 2017 the Stadio della Roma project, after experiencing five years worth of delays due to conflicting interests from various parties in the Roman city government, was given the go-ahead to begin construction, with the stadium expected to be ready to open for the 2020–21 season. On 26 February 2021, it was announced that the stadium project was halted. List of stadiums used by the club 1927–1928 Motovelodromo Appio 1929–1940 Campo Testaccio 1940–1953 Stadio Nazionale del PNF 1953– Stadio Olimpico (1989–1990 Stadio Flaminio due to renovations on Olimpico) Trigoria A sports centre located in Trigoria at kilometre 3600 in south-east of Rome was purchased on 22 July 1977 by then club president Gaetano Anzalone. It was opened on 23 July 1979 as Anzalone's final act as president. The complex had its first expansion in 1984 when the club was handled by Dino Viola and another in 1998 under the chairmanship of Franco Sensi. The centre's official name is the Fulvio Bernardini di Trigoria, named after club icon Fulvio Bernardini. On 4 September 2019, the Trigoria training ground began to serve also as a private school named 'Liceo Scientifico Sportivo A.S. Roma' exclusively educating only the team's youth players in a renovated building on the training ground premises. 80 students are currently enrolled in the school which features its own cafeteria and gym. The centre is also known for hosting the Argentina national team during the 1990 FIFA World Cup, held in Italy. Supporters Roma is the fifth-most supported football club in Italy – behind Juventus, Internazionale, A.C. Milan and Napoli – with approximately 7% of Italian football fans supporting the club, according to the Doxa Institute-L'Espresso's research of April 2006. Historically, the largest section of Roma supporters in the city of Rome have come from the inner-city, especially Testaccio. The traditional ultras group of the club was Commando Ultrà Curva Sud commonly abbreviated as CUCS. This group was founded by the merger of many smaller groups and was considered one of the most historic in the history of European football. However, by the mid-1990s, CUCS had been usurped by rival factions and ultimately broke up. Since that time, the Curva Sud of the Stadio Olimpico has been controlled by more right-wing groups, including A.S. Roma Ultras, Boys and Giovinezza, among others. However, the oldest group, Fedayn, is apolitical, and politics is not the main identity of Roma, just a part of their overall identity. Besides ultras groups, it is believed Roma fans support the left as opposed to Lazio supporters, which are notoriously proud of their right-wing affiliation. In November 2015, Roma's ultras and their Lazio counterparts boycotted Roma's 1–0 victory in the Derby della Capitale in protest at new safety measures imposed at the Stadio Olimpico. The measures – imposed by Rome's prefect, Franco Gabrielli – had involved plastic glass dividing walls being installed in both the Curva Sud and Curva Nord, splitting the sections behind each goal in two. Both sets of ultras continued their protests for the rest of the season, including during Roma's 4–1 victory in the return fixture. Lazio's ultras returned to the Curva Nord for Roma's 1–4 victory in December 2016, but the Roma ultras continue to boycott matches. The most known club anthem is "Roma (non-si discute, si ama)", also known as "Roma Roma", by singer Antonello Venditti. The title roughly means, "Roma is not to be questioned, it is to be loved," and it is sung before each match. The song "Grazie Roma", by the same singer, is played at the end of victorious home matches. Recently, the main riff of The White Stripes' song "Seven Nation Army" has also become widely popular at matches. Rivalries In Italian football, Roma is a club with many rivalries; first and foremost is their rivalry with Lazio, the club with whom they share the Stadio Olimpico. The derby between the two is called the Derby della Capitale, it is amongst the most heated and emotional footballing rivalries in the world. The fixture has seen some occasional instances of violence in the past, including the death of Lazio fan Vincenzo Paparelli in 1979–80 as a result of an emergency flare fired from the Curva Sud, and the abandonment of a match in March 2004 following unfounded rumours of a fatality which led to violence outside the stadium. Against Napoli, Roma also compete in the Derby del Sole, meaning the "Derby of the Sun". Nowadays, fans also consider other Juventus (a rivalry born especially in the 1980s), Milan, Atalanta (since 1984, when friendly relations between the two clubs' ultras deteriorated), and Internazionale (increased in recent years) among their rivals, as they are often competitors for the top four spots in the league table and qualification for the UEFA Champions League. Hooliganism Rivalries with other teams have escalated into serious violence. A group of ultras who label themselves the Fedayn — 'the devotees' — after a group of long-forgotten Iranian guerrilla fighters are regarded to be responsible for the organised hooliganism. In 2014 Daniele De Santis, a Roma ultra, was convicted of shooting Ciro Esposito and two others during clashes with Napoli fans who were in Rome for their club's Coppa Italia final against Fiorentina. Esposito died of his wounds. De Santis was sentenced to 26 years in prison, later reduced to 16 years on appeal. Roma ultras have displayed banners celebrating De Santis. There have been multiple instances of Roma ultras attacking supporters of foreign clubs when playing in Rome. These attacks have regularly featured the Roma ultras using knives, poles, flares, bottles and stones on unarmed foreign supporters, resulting in multiple hospitalisations. Home games against Liverpool in 1984 and 2001, Middlesbrough in 2006, Manchester United in 2007, Arsenal in 2009, Tottenham Hotspur in 2012, and Chelsea in 2017 have all resulted in multiple stabbings and other injuries to foreign supporters. In 2018 Roma ultras travelling to an away game at Liverpool attacked home supporters, resulting in a home supporter being critically injured. Players Current squad Primavera squad Out on loan Women team Notable players Retired numbers Since 2017, Roma had not issued the squad number 10 to commemorate Francesco Totti, who was retired from football since 2017. It was going to be issued to Paulo Dybala in 2022, but Dybala chose the number 21 instead of number 10. (1993–2017) Management staff Chairmen history Roma have had numerous chairmen ( or ) over the course of their history, some of which have been the owners and co-owners of the club, some of them were nominated by the owners. Franco Sensi was the chairman until his death in 2008, with his daughter, Roma CEO Rosella Sensi taking his place as chairman. Here is a complete list of Roma chairmen from 1927 until the present day. Managerial history Roma have had many managers and trainers running the team during their history, here is a chronological list of them from 1927 onwards.

The Hall of Fame players were voted via the club's official website and a special Hall of Fame panel. In 2013 four players were voted in. In 2014, the third year of AS Roma Hall of Fame four more players were voted in. Added in 2012: Franco Tancredi (1977–90) Cafu (1997–03) Giacomo Losi (1954–69) Aldair (1990-03) Francesco Rocca (1972–81) Fulvio Bernardini (1928–39) Agostino Di Bartolomei (1972–75; 1976–84) Falcão (1980–85) Bruno Conti (1973–75; 1976–78; 1979–91) Roberto Pruzzo (1978–88) Amedeo Amadei (1936–38; 1939–48) Added in 2013: Attilio Ferraris (1927–34; 1938–39) Sebino Nela (1981–92) Giuseppe Giannini (1981–96) Vincenzo Montella (1999–2009) Added in 2014: Alcides Ghiggia (1953–61) Carlo Ancelotti (1979–87) Rudi Völler (1987–92) Vincent Candela (1997–2005) Added in 2015: Guido Masetti (1930–43) Sergio Santarini (1968–81) Damiano Tommasi (1996–2006) Gabriel Batistuta (2000–03) Added in 2016: Giorgio Carpi (1927–37) Toninho Cerezo (1983–86) Giancarlo De Sisti (1960–65; 1974–79) Arcadio Venturi (1948–57) Added in 2017: Francesco Totti (1992–2017) Added in 2018: Mario De Micheli (1927–1932) Giuliano Taccola (1967–1969) Rodolfo Volk (1928–1933) Club records and statistics Francesco Totti currently holds Roma's official appearance record, having made 786 appearances in all competitions, over the course of 25 seasons from 1993 until 2017. He also holds the record for Serie A appearances with 619, as he passed Giacomo Losi on 1 March 2008 during a home match against Parma. Including all competitions, Totti is the all-time leading goalscorer for Roma with 307 goals since joining the club, 250 of which were scored in Serie A (another Roma record). Roberto Pruzzo, who was the all-time topscorer since 1988, comes in second in all competitions with 138. In 1930–31, Rodolfo Volk scored 29 goals in Serie A over the course of a single season. Not only was Volk the league's top scorer that year, he also set a Roma record for most goals scored in a season which would later be matched by Edin Džeko in 2016–17. Its major founders Fortitudo and Alba having been relegated at the end of 1926–27 campaign, new-founded Roma had to take part to Southern First Division championship (Serie B) for its inaugural season. Nevertheless, the FIGC decided on a special enlargement of first level division re-admitting AS Roma and SSC Napoli. The first ever official matches participated in by Roma was in the National Division, the predecessor of Serie A, of 1927–28, against Livorno, a 2–0 Roma win. The biggest ever victory recorded by Roma was 9–0 against Cremonese during the 1929–30 Serie A season. The heaviest defeat Roma have ever suffered is 1–7, which has occurred five times; against Juventus in 1931–32, Torino in 1947–48, Manchester United in 2006–07, Bayern Munich in 2014–15 and Fiorentina in 2018–19. Divisional movements UEFA Club Coefficient Ranking UEFA Rankings since 2004 Football Club Elo Ranking As a company Since 1999, during Franco Sensi's period in charge, Associazione Sportiva Roma has been a listed on Borsa Italiana. From 2004 to 2011, Roma's shares are distributed between; 67.1% to Compagnia Italpetroli SpA (the Sensi family holding; Banca di Roma later acquired 49% stake on Italpetroli due to debt restructuring) and 32.9% to other public shareholders. Along with Lazio and Juventus, Roma is one of only three quotated Italian clubs. According to The Football Money League published by consultants Deloitte, in the 2010–11 season, Roma was the 15th highest-earning football club in the world with an estimated revenue of €143.5 million. In April 2008, after months of speculation, George Soros was confirmed by Rosella Sensi, CEO of Serie A club A.S. Roma, to be bidding for a takeover. The takeover bid was successively rejected by the Sensi family, who instead preferred to maintain the club's ownership. On 17 August 2008 club chairman and owner Franco Sensi died after a long illness; his place at the chairmanship of the club was successively taken by his daughter Rosella. Since the takeover in 2011, NEEP Roma Holding S.p.A. has owned all shares Sensi previously hold. NEEP, itself a joint venture, was held by DiBenedetto AS Roma LLC (later renamed to AS Roma SPV, LLC) and Unicredit in 60–40 ratio from 2011 to 2013, which the former had four real person shareholders in equal ratio, led by future Roma president Thomas R. DiBenedetto (2011–12). The takeover also activated a mandatory bid of shares from the general public, however not all minority shareholders were willing to sell their shares. The mandatory bid meant NEEP held 78.038% of shares of AS Roma (increased from 67.1% of the Sensi). On 1 August 2013, the president of Roma as well as one of the four American shareholders of AS Roma SPV, LLC, James Pallotta, bought an additional 9% shares of NEEP Roma Holding from Unicredit (through Raptor Holdco LLC), as the bank was not willing to fully participate in the capital increase of NEEP from €120,000 to €160,008,905 (excluding share premium). On 4 April 2014 Starwood Capital Group also became the fifth shareholder of AS Roma SPV, as well as forming a strategic partnership with AS Roma SpA to develop real estate around the new stadium. The private investment firm was represented by Zsolt Kohalmi in AS Roma SPV, who was appointed on 4 April as a partner and head of European acquisitions of the firm. On 11 August 2014, UniCredit sold the remain shares on NEEP (of 31%) for €33 million which meant AS Roma SPV LLC (91%) and Raptor Holdco LLC (9%) were the sole intermediate holding company of AS Roma SpA. Since re-capitalization in 2003–04, Roma had a short-lived financial self-sustainability, until the takeover in 2011. The club had set up a special amortisation fund using Articolo 18-bis Legge 91/1981 mainly for the abnormal signings prior 2002–03 season, (such as Davide Bombardini for €11 million account value in June 2002, when the flopped player exchange boosted 2001–02 season result) and the tax payment of 2002–03 was rescheduled. In 2004–05, Roma made a net profit of €10,091,689 and followed by €804,285 in 2005–06. In 2006–07 season the accounting method changed to IFRS, which meant that the 2005–06 result was reclassified as net loss of €4,051,905 and 2006–07 season was net income of €10,135,539 (€14.011 million as a group). Moreover, the special fund (€80,189,123) was removed from the asset and co-currently for the equity as scheduled, meant Roma group had a negative equity of €8.795 million on 30 June 2007. Nevertheless, the club had sold the brand to a subsidiary which boost the profit in a separate financial statement, which La Repubblica described as "doping". In 2007–08, Roma made a net income of €18,699,219. (€19 million as a group) However, 2008–09 saw the decrease of gate and TV income, co-currently with finishing sixth in Serie A, which saw Roma make a net loss of €1,894,330. (€1.56 million as a group) The gate and TV income further slipped in 2009–10 with a net loss of €21,917,292 (already boosted by the sale of Alberto Aquilani; €22 million as a group) despite sporting success (finishing in second place in 2009–10). Moreover, despite a positive equity as a separate company (€105,142,589), the AS Roma Group had a negative equity on the consolidated balance sheet, and fell from +€8.8 million to −€13.2 million. In the 2010–11 season, Roma was administered by UniCredit as the Sensi family failed to repay the bank and the club was put on the market, and were expected to have a quiet transfer window. Concurrently with no selling profit on the players, Roma's net loss rose to €30,589,137 (€30.778 million as a group) and the new owner already planned a re-capitalization after the mandatory bid on the shares. On the positive side, TV income was increased from €75,150,744 to €78,041,642, and gate income increased from €23,821,218 to €31,017,179. This was because Roma entered 2010–11 Champions League, which counter-weighed the effect of the new collective agreement of Serie A. In 2011–12, the renewal of squad and participation in 2011–12 UEFA Europa League had worsened the financial result, which the €50 million capital increase (in advance) was counter-weighted totally by the net loss. In the 2012–13 season, the participation in domestic league only, was not only not harmful to the revenue but increase in gate income as well as decrease in wage bill, however Roma still did not yet break even (€40.130 million net loss in consolidated accounts). NEEP Roma also re-capitalized AS Roma in advance for another €26,550,000 during 2012–13. A proposed capital increase by €100 million for Roma was announced on 25 June 2014; however, until 22 May 2014, NEEP already injected €108 million into the club, which depends on public subscription; more than €8 million would convert to medium-long-term loan from shareholder instead of becoming share capital. Another capital increase was carried in 2018. A joint venture of Roma, which was owned by Roma (37.5%), S.S. Lazio (37.5%) and Parma F.C.(25%), Società Diritti Sportivi S.r.l., was in the process of liquidation since 2005. The company was a joint-venture of four football clubs, including Fiorentina. After the bankruptcy of Fiorentina however, both Roma and Lazio had increased their shares ratio from 25% to 37.5%. Another subsidiary, "Soccer S.A.S. di Brand Management S.r.l.", was a special-purpose entity (SPV) that Roma sold their brand to the subsidiary in 2007. In February 2015, another SPV, "ASR Media and Sponsorship S.r.l", was set up to secure a five-year bank loan of €175 million from Goldman Sachs, for three-month Euribor (min. 0.75%) + 6.25% spread (i.e. min. 7% interests rate p.a.). In 2015, Inter and Roma were the only two Italian clubs that were sanctioned by UEFA for breaking UEFA Financial Fair Play Regulations, which they signed settlement agreements with UEFA. It was followed by Milan in 2018. Roma had compliance with the requirements and overall objective of the settlement agreement in 2018, which the club exited from settlement regime. Superleague Formula A.S. Roma had a team in the Superleague Formula race car series where teams were sponsored by football clubs. Roma's driver was ex-IndyCar Series driver Franck Perera. The team had posted three podiums and was operated by Alan Docking Racing. See also Football in Italy European Club Association Footnotes References External links A.S. Roma at Serie A A.S.

An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize it directly (for example, by blocking a part of a virus that is essential for its invasion). To allow the immune system to recognize millions of different antigens, the antigen-binding sites at both tips of the antibody come in an equally wide variety. In contrast, the remainder of the antibody is relatively constant. In mammals, antibodies occur in a few variants, which define the antibody's class or isotype: IgA, IgD, IgE, IgG, and IgM. The constant region at the trunk of the antibody includes sites involved in interactions with other components of the immune system. The class hence determines the function triggered by an antibody after binding to an antigen, in addition to some structural features. Antibodies from different classes also differ in where they are released in the body and at what stage of an immune response. Together with B and T cells, antibodies comprise the most important part of the adaptive immune system. They occur in two forms: one that is attached to a B cell, and the other, a soluble form, that is unattached and found in extracellular fluids such as blood plasma. Initially, all antibodies are of the first form, attached to the surface of a B cell – these are then referred to as B-cell receptors (BCR). After an antigen binds to a BCR, the B cell activates to proliferate and differentiate into either plasma cells, which secrete soluble antibodies with the same paratope, or memory B cells, which survive in the body to enable long-lasting immunity to the antigen. Soluble antibodies are released into the blood and tissue fluids, as well as many secretions. Because these fluids were traditionally known as humors, antibody-mediated immunity is sometimes known as, or considered a part of, humoral immunity. The soluble Y-shaped units can occur individually as monomers, or in complexes of two to five units. Antibodies are glycoproteins belonging to the immunoglobulin superfamily. The terms antibody and immunoglobulin are often used interchangeably, though the term 'antibody' is sometimes reserved for the secreted, soluble form, i.e. excluding B-cell receptors. Structure Antibodies are heavy (~150 kDa) proteins of about 10 nm in size, arranged in three globular regions that roughly form a Y shape. In humans and most other mammals, an antibody unit consists of four polypeptide chains; two identical heavy chains and two identical light chains connected by disulfide bonds. Each chain is a series of domains: somewhat similar sequences of about 110 amino acids each. These domains are usually represented in simplified schematics as rectangles. Light chains consist of one variable domain VL and one constant domain CL, while heavy chains contain one variable domain VH and three to four constant domains CH1, CH2, ... Structurally an antibody is also partitioned into two antigen-binding fragments (Fab), containing one VL, VH, CL, and CH1 domain each, as well as the crystallisable fragment (Fc), forming the trunk of the Y shape. In between them is a hinge region of the heavy chains, whose flexibility allows antibodies to bind to pairs of epitopes at various distances, to form complexes (dimers, trimers, etc.), and to bind effector molecules more easily. In an electrophoresis test of blood proteins, antibodies mostly migrate to the last, gamma globulin fraction. Conversely, most gamma-globulins are antibodies, which is why the two terms were historically used as synonyms, as were the symbols Ig and γ. This variant terminology fell out of use due to the correspondence being inexact and due to confusion with γ (gamma) heavy chains which characterize the IgG class of antibodies. Antigen-binding site The variable domains can also be referred to as the FV region. It is the subregion of Fab that binds to an antigen. More specifically, each variable domain contains three hypervariable regions – the amino acids seen there vary the most from antibody to antibody. When the protein folds, these regions give rise to three loops of β-strands, localized near one another on the surface of the antibody. These loops are referred to as the complementarity-determining regions (CDRs), since their shape complements that of an antigen. Three CDRs from each of the heavy and light chains together form an antibody-binding site whose shape can be anything from a pocket to which a smaller antigen binds, to a larger surface, to a protrusion that sticks out into a groove in an antigen. Typically however only a few residues contribute to most of the binding energy. The existence of two identical antibody-binding sites allows antibody molecules to bind strongly to multivalent antigen (repeating sites such as polysaccharides in bacterial cell walls, or other sites at some distance apart), as well as to form antibody complexes and larger antigen-antibody complexes. The resulting cross-linking plays a role in activating other parts of the immune system. The structures of CDRs have been clustered and classified by Chothia et al. and more recently by North et al. and Nikoloudis et al. However, describing an antibody's binding site using only one single static structure limits the understanding and characterization of the antibody's function and properties. To improve antibody structure prediction and to take the strongly correlated CDR loop and interface movements into account, antibody paratopes should be described as interconverting states in solution with varying probabilities. In the framework of the immune network theory, CDRs are also called idiotypes. According to immune network theory, the adaptive immune system is regulated by interactions between idiotypes. Fc region The Fc region (the trunk of the Y shape) is composed of constant domains from the heavy chains. Its role is in modulating immune cell activity: it is where effector molecules bind to, triggering various effects after the antibody Fab region binds to an antigen. Effector cells (such as macrophages or natural killer cells) bind via their Fc receptors (FcR) to the Fc region of an antibody, while the complement system is activated by binding the C1q protein complex. IgG or IgM can bind to C1q, but IgA cannot, therefore IgA does not activate the classical complement pathway. Another role of the Fc region is to selectively distribute different antibody classes across the body. In particular, the neonatal Fc receptor (FcRn) binds to the Fc region of IgG antibodies to transport it across the placenta, from the mother to the fetus. Antibodies are glycoproteins, that is, they have carbohydrates (glycans) added to conserved amino acid residues. These conserved glycosylation sites occur in the Fc region and influence interactions with effector molecules. Protein structure The N-terminus of each chain is situated at the tip. Each immunoglobulin domain has a similar structure, characteristic of all the members of the immunoglobulin superfamily: it is composed of between 7 (for constant domains) and 9 (for variable domains) β-strands, forming two beta sheets in a Greek key motif. The sheets create a "sandwich" shape, the immunoglobulin fold, held together by a disulfide bond. Antibody complexes Secreted antibodies can occur as a single Y-shaped unit, a monomer. However, some antibody classes also form dimers with two Ig units (as with IgA), tetramers with four Ig units (like teleost fish IgM), or pentamers with five Ig units (like shark IgW or mammalian IgM, which occasionally forms hexamers as well, with six units). Antibodies also form complexes by binding to antigen: this is called an antigen-antibody complex or immune complex. Small antigens can cross-link two antibodies, also leading to the formation of antibody dimers, trimers, tetramers, etc. Multivalent antigens (e.g., cells with multiple epitopes) can form larger complexes with antibodies. An extreme example is the clumping, or agglutination, of red blood cells with antibodies in the Coombs test to determine blood groups: the large clumps become insoluble, leading to visually apparent precipitation. B cell receptors The membrane-bound form of an antibody may be called a surface immunoglobulin (sIg) or a membrane immunoglobulin (mIg). It is part of the B cell receptor (BCR), which allows a B cell to detect when a specific antigen is present in the body and triggers B cell activation. The BCR is composed of surface-bound IgD or IgM antibodies and associated Ig-α and Ig-β heterodimers, which are capable of signal transduction. A typical human B cell will have 50,000 to 100,000 antibodies bound to its surface. Upon antigen binding, they cluster in large patches, which can exceed 1 micrometer in diameter, on lipid rafts that isolate the BCRs from most other cell signaling receptors. These patches may improve the efficiency of the cellular immune response. In humans, the cell surface is bare around the B cell receptors for several hundred nanometers, which further isolates the BCRs from competing influences. Classes Antibodies can come in different varieties known as isotypes or classes. In placental mammals there are five antibody classes known as IgA, IgD, IgE, IgG, and IgM, which are further subdivided into subclasses such as IgA1, IgA2. The prefix "Ig" stands for immunoglobulin, while the suffix denotes the type of heavy chain the antibody contains: the heavy chain types α (alpha), γ (gamma), δ (delta), ε (epsilon), μ (mu) give rise to IgA, IgG, IgD, IgE, IgM, respectively. The distinctive features of each class are determined by the part of the heavy chain within the hinge and Fc region. The classes differ in their biological properties, functional locations and ability to deal with different antigens, as depicted in the table. For example, IgE antibodies are responsible for an allergic response consisting of histamine release from mast cells, often a sole contributor to asthma (though other pathways exist as do exist symptoms very similar to yet not technically asthma). The antibody's variable region binds to allergic antigen, for example house dust mite particles, while its Fc region (in the ε heavy chains) binds to Fc receptor ε on a mast cell, triggering its degranulation: the release of molecules stored in its granules. The antibody isotype of a B cell changes during cell development and activation. Immature B cells, which have never been exposed to an antigen, express only the IgM isotype in a cell surface bound form. The B lymphocyte, in this ready-to-respond form, is known as a "naive B lymphocyte." The naive B lymphocyte expresses both surface IgM and IgD. The co-expression of both of these immunoglobulin isotypes renders the B cell ready to respond to antigen. B cell activation follows engagement of the cell-bound antibody molecule with an antigen, causing the cell to divide and differentiate into an antibody-producing cell called a plasma cell. In this activated form, the B cell starts to produce antibody in a secreted form rather than a membrane-bound form. Some daughter cells of the activated B cells undergo isotype switching, a mechanism that causes the production of antibodies to change from IgM or IgD to the other antibody isotypes, IgE, IgA, or IgG, that have defined roles in the immune system. Light chain types In mammals there are two types of immunoglobulin light chain, which are called lambda (λ) and kappa (κ). However, there is no known functional difference between them, and both can occur with any of the five major types of heavy chains. Each antibody contains two identical light chains: both κ or both λ. Proportions of κ and λ types vary by species and can be used to detect abnormal proliferation of B cell clones. Other types of light chains, such as the iota (ι) chain, are found in other vertebrates like sharks (Chondrichthyes) and bony fishes (Teleostei). In non-mammalian animals In most placental mammals, the structure of antibodies is generally the same. Jawed fish appear to be the most primitive animals that are able to make antibodies similar to those of mammals, although many features of their adaptive immunity appeared somewhat earlier. Cartilaginous fish (such as sharks) produce heavy-chain-only antibodies (i.e., lacking light chains) which moreover feature longer chain pentamers (with five constant units per molecule). Camelids (such as camels, llamas, alpacas) are also notable for producing heavy-chain-only antibodies. Antibody–antigen interactions The antibody's paratope interacts with the antigen's epitope. An antigen usually contains different epitopes along its surface arranged discontinuously, and dominant epitopes on a given antigen are called determinants. Antibody and antigen interact by spatial complementarity (lock and key). The molecular forces involved in the Fab-epitope interaction are weak and non-specific – for example electrostatic forces, hydrogen bonds, hydrophobic interactions, and van der Waals forces. This means binding between antibody and antigen is reversible, and the antibody's affinity towards an antigen is relative rather than absolute. Relatively weak binding also means it is possible for an antibody to cross-react with different antigens of different relative affinities. Function The main categories of antibody action include the following: Neutralisation, in which neutralizing antibodies block parts of the surface of a bacterial cell or virion to render its attack ineffective Agglutination, in which antibodies "glue together" foreign cells into clumps that are attractive targets for phagocytosis Precipitation, in which antibodies "glue together" serum-soluble antigens, forcing them to precipitate out of solution in clumps that are attractive targets for phagocytosis Complement activation (fixation), in which antibodies that are latched onto a foreign cell encourage complement to attack it with a membrane attack complex, which leads to the following: Lysis of the foreign cell Encouragement of inflammation by chemotactically attracting inflammatory cells More indirectly, an antibody can signal immune cells to present antibody fragments to T cells, or downregulate other immune cells to avoid autoimmunity. Activated B cells differentiate into either antibody-producing cells called plasma cells that secrete soluble antibody or memory cells that survive in the body for years afterward in order to allow the immune system to remember an antigen and respond faster upon future exposures. At the prenatal and neonatal stages of life, the presence of antibodies is provided by passive immunization from the mother. Early endogenous antibody production varies for different kinds of antibodies, and usually appear within the first years of life. Since antibodies exist freely in the bloodstream, they are said to be part of the humoral immune system. Circulating antibodies are produced by clonal B cells that specifically respond to only one antigen (an example is a virus capsid protein fragment). Antibodies contribute to immunity in three ways: They prevent pathogens from entering or damaging cells by binding to them; they stimulate removal of pathogens by macrophages and other cells by coating the pathogen; and they trigger destruction of pathogens by stimulating other immune responses such as the complement pathway. Antibodies will also trigger vasoactive amine degranulation to contribute to immunity against certain types of antigens (helminths, allergens). Activation of complement Antibodies that bind to surface antigens (for example, on bacteria) will attract the first component of the complement cascade with their Fc region and initiate activation of the "classical" complement system. This results in the killing of bacteria in two ways. First, the binding of the antibody and complement molecules marks the microbe for ingestion by phagocytes in a process called opsonization; these phagocytes are attracted by certain complement molecules generated in the complement cascade. Second, some complement system components form a membrane attack complex to assist antibodies to kill the bacterium directly (bacteriolysis). Activation of effector cells To combat pathogens that replicate outside cells, antibodies bind to pathogens to link them together, causing them to agglutinate. Since an antibody has at least two paratopes, it can bind more than one antigen by binding identical epitopes carried on the surfaces of these antigens. By coating the pathogen, antibodies stimulate effector functions against the pathogen in cells that recognize their Fc region. Those cells that recognize coated pathogens have Fc receptors, which, as the name suggests, interact with the Fc region of IgA, IgG, and IgE antibodies. The engagement of a particular antibody with the Fc receptor on a particular cell triggers an effector function of that cell; phagocytes will phagocytose, mast cells and neutrophils will degranulate, natural killer cells will release cytokines and cytotoxic molecules; that will ultimately result in destruction of the invading microbe. The activation of natural killer cells by antibodies initiates a cytotoxic mechanism known as antibody-dependent cell-mediated cytotoxicity (ADCC) – this process may explain the efficacy of monoclonal antibodies used in biological therapies against cancer. The Fc receptors are isotype-specific, which gives greater flexibility to the immune system, invoking only the appropriate immune mechanisms for distinct pathogens. Natural antibodies Humans and higher primates also produce "natural antibodies" that are present in serum before viral infection. Natural antibodies have been defined as antibodies that are produced without any previous infection, vaccination, other foreign antigen exposure or passive immunization. These antibodies can activate the classical complement pathway leading to lysis of enveloped virus particles long before the adaptive immune response is activated. Many natural antibodies are directed against the disaccharide galactose α(1,3)-galactose (α-Gal), which is found as a terminal sugar on glycosylated cell surface proteins, and generated in response to production of this sugar by bacteria contained in the human gut. Rejection of xenotransplantated organs is thought to be, in part, the result of natural antibodies circulating in the serum of the recipient binding to α-Gal antigens expressed on the donor tissue. Immunoglobulin diversity Virtually all microbes can trigger an antibody response. Successful recognition and eradication of many different types of microbes requires diversity among antibodies; their amino acid composition varies allowing them to interact with many different antigens. It has been estimated that humans generate about 10 billion different antibodies, each capable of binding a distinct epitope of an antigen. Although a huge repertoire of different antibodies is generated in a single individual, the number of genes available to make these proteins is limited by the size of the human genome. Several complex genetic mechanisms have evolved that allow vertebrate B cells to generate a diverse pool of antibodies from a relatively small number of antibody genes. Domain variability The chromosomal region that encodes an antibody is large and contains several distinct gene loci for each domain of the antibody—the chromosome region containing heavy chain genes (IGH@) is found on chromosome 14, and the loci containing lambda and kappa light chain genes (IGL@ and IGK@) are found on chromosomes 22 and 2 in humans. One of these domains is called the variable domain, which is present in each heavy and light chain of every antibody, but can differ in different antibodies generated from distinct B cells. Differences between the variable domains are located on three loops known as hypervariable regions (HV-1, HV-2 and HV-3) or complementarity-determining regions (CDR1, CDR2 and CDR3). CDRs are supported within the variable domains by conserved framework regions. The heavy chain locus contains about 65 different variable domain genes that all differ in their CDRs. Combining these genes with an array of genes for other domains of the antibody generates a large cavalry of antibodies with a high degree of variability. This combination is called V(D)J recombination discussed below. V(D)J recombination Somatic recombination of immunoglobulins, also known as V(D)J recombination, involves the generation of a unique immunoglobulin variable region. The variable region of each immunoglobulin heavy or light chain is encoded in several pieces—known as gene segments (subgenes). These segments are called variable (V), diversity (D) and joining (J) segments. V, D and J segments are found in Ig heavy chains, but only V and J segments are found in Ig light chains. Multiple copies of the V, D and J gene segments exist, and are tandemly arranged in the genomes of mammals. In the bone marrow, each developing B cell will assemble an immunoglobulin variable region by randomly selecting and combining one V, one D and one J gene segment (or one V and one J segment in the light chain). As there are multiple copies of each type of gene segment, and different combinations of gene segments can be used to generate each immunoglobulin variable region, this process generates a huge number of antibodies, each with different paratopes, and thus different antigen specificities. The rearrangement of several subgenes (i.e. V2 family) for lambda light chain immunoglobulin is coupled with the activation of microRNA miR-650, which further influences biology of B-cells. RAG proteins play an important role with V(D)J recombination in cutting DNA at a particular region. Without the presence of these proteins, V(D)J recombination would not occur. After a B cell produces a functional immunoglobulin gene during V(D)J recombination, it cannot express any other variable region (a process known as allelic exclusion) thus each B cell can produce antibodies containing only one kind of variable chain. Somatic hypermutation and affinity maturation Following activation with antigen, B cells begin to proliferate rapidly. In these rapidly dividing cells, the genes encoding the variable domains of the heavy and light chains undergo a high rate of point mutation, by a process called somatic hypermutation (SHM). SHM results in approximately one nucleotide change per variable gene, per cell division. As a consequence, any daughter B cells will acquire slight amino acid differences in the variable domains of their antibody chains. This serves to increase the diversity of the antibody pool and impacts the antibody's antigen-binding affinity. Some point mutations will result in the production of antibodies that have a weaker interaction (low affinity) with their antigen than the original antibody, and some mutations will generate antibodies with a stronger interaction (high affinity). B cells that express high affinity antibodies on their surface will receive a strong survival signal during interactions with other cells, whereas those with low affinity antibodies will not, and will die by apoptosis. Thus, B cells expressing antibodies with a higher affinity for the antigen will outcompete those with weaker affinities for function and survival allowing the average affinity of antibodies to increase over time. The process of generating antibodies with increased binding affinities is called affinity maturation. Affinity maturation occurs in mature B cells after V(D)J recombination, and is dependent on help from helper T cells. Class switching Isotype or class switching is a biological process occurring after activation of the B cell, which allows the cell to produce different classes of antibody (IgA, IgE, or IgG). The different classes of antibody, and thus effector functions, are defined by the constant (C) regions of the immunoglobulin heavy chain. Initially, naive B cells express only cell-surface IgM and IgD with identical antigen binding regions. Each isotype is adapted for a distinct function; therefore, after activation, an antibody with an IgG, IgA, or IgE effector function might be required to effectively eliminate an antigen. Class switching allows different daughter cells from the same activated B cell to produce antibodies of different isotypes. Only the constant region of the antibody heavy chain changes during class switching; the variable regions, and therefore antigen specificity, remain unchanged. Thus the progeny of a single B cell can produce antibodies, all specific for the same antigen, but with the ability to produce the effector function appropriate for each antigenic challenge. Class switching is triggered by cytokines; the isotype generated depends on which cytokines are present in the B cell environment. Class switching occurs in the heavy chain gene locus by a mechanism called class switch recombination (CSR). This mechanism relies on conserved nucleotide motifs, called switch (S) regions, found in DNA upstream of each constant region gene (except in the δ-chain). The DNA strand is broken by the activity of a series of enzymes at two selected S-regions. The variable domain exon is rejoined through a process called non-homologous end joining (NHEJ) to the desired constant region (γ, α or ε). This process results in an immunoglobulin gene that encodes an antibody of a different isotype. Specificity designations An antibody can be called monospecific if it has specificity for the same antigen or epitope, or bispecific if they have affinity for two different antigens or two different epitopes on the same antigen. A group of antibodies can be called polyvalent (or unspecific) if they have affinity for various antigens or microorganisms. Intravenous immunoglobulin, if not otherwise noted, consists of a variety of different IgG (polyclonal IgG). In contrast, monoclonal antibodies are identical antibodies produced by a single B cell. Asymmetrical antibodies Heterodimeric antibodies, which are also asymmetrical antibodies, allow for greater flexibility and new formats for attaching a variety of drugs to the antibody arms. One of the general formats for a heterodimeric antibody is the "knobs-into-holes" format. This format is specific to the heavy chain part of the constant region in antibodies. The "knobs" part is engineered by replacing a small amino acid with a larger one. It fits into the "hole", which is engineered by replacing a large amino acid with a smaller one. What connects the "knobs" to the "holes" are the disulfide bonds between each chain. The "knobs-into-holes" shape facilitates antibody dependent cell mediated cytotoxicity. Single chain variable fragments (scFv) are connected to the variable domain of the heavy and light chain via a short linker peptide. The linker is rich in glycine, which gives it more flexibility, and serine/threonine, which gives it specificity. Two different scFv fragments can be connected together, via a hinge region, to the constant domain of the heavy chain or the constant domain of the light chain. This gives the antibody bispecificity, allowing for the binding specificities of two different antigens. The "knobs-into-holes" format enhances heterodimer formation but does not suppress homodimer formation. To further improve the function of heterodimeric antibodies, many scientists are looking towards artificial constructs. Artificial antibodies are largely diverse protein motifs that use the functional strategy of the antibody molecule, but are not limited by the loop and framework structural constraints of the natural antibody. Being able to control the combinational design of the sequence and three-dimensional space could transcend the natural design and allow for the attachment of different combinations of drugs to the arms. Heterodimeric antibodies have a greater range in shapes they can take and the drugs that are attached to the arms do not have to be the same on each arm, allowing for different combinations of drugs to be used in cancer treatment. Pharmaceuticals are able to produce highly functional bispecific, and even multispecific, antibodies. The degree to which they can function is impressive given that such a change of shape from the natural form should lead to decreased functionality. History The first use of the term "antibody" occurred in a text by Paul Ehrlich. The term Antikörper (the German word for antibody) appears in the conclusion of his article "Experimental Studies on Immunity", published in October 1891, which states that, "if two substances give rise to two different Antikörper, then they themselves must be different". However, the term was not accepted immediately and several other terms for antibody were proposed; these included Immunkörper, Amboceptor, Zwischenkörper, substance sensibilisatrice, copula, Desmon, philocytase, fixateur, and Immunisin. The word antibody has formal analogy to the word antitoxin and a similar concept to Immunkörper (immune body in English). As such, the original construction of the word contains a logical flaw; the antitoxin is something directed against a toxin, while the antibody is a body directed against something. The study of antibodies began in 1890 when Emil von Behring and Kitasato Shibasaburō described antibody activity against diphtheria and tetanus toxins. Von Behring and Kitasato put forward the theory of humoral immunity, proposing that a mediator in serum could react with a foreign antigen. His idea prompted Paul Ehrlich to propose the side-chain theory for antibody and antigen interaction in 1897, when he hypothesized that receptors (described as "side-chains") on the surface of cells could bind specifically to toxins – in a "lock-and-key" interaction – and that this binding reaction is the trigger for the production of antibodies. Other researchers believed that antibodies existed freely in the blood and, in 1904, Almroth Wright suggested that soluble antibodies coated bacteria to label them for phagocytosis and killing; a process that he named opsoninization. In the 1920s, Michael Heidelberger and Oswald Avery observed that antigens could be precipitated by antibodies and went on to show that antibodies are made of protein. The biochemical properties of antigen-antibody-binding interactions were examined in more detail in the late 1930s by John Marrack. The next major advance was in the 1940s, when Linus Pauling confirmed the lock-and-key theory proposed by Ehrlich by showing that the interactions between antibodies and antigens depend more on their shape than their chemical composition. In 1948, Astrid Fagraeus discovered that B cells, in the form of plasma cells, were responsible for generating antibodies. Further work concentrated on characterizing the structures of the antibody proteins. A major advance in these structural studies was the discovery in the early 1960s by Gerald Edelman and Joseph Gally of the antibody light chain, and their realization that this protein is the same as the Bence-Jones protein described in 1845 by Henry Bence Jones. Edelman went on to discover that antibodies are composed of disulfide bond-linked heavy and light chains. Around the same time, antibody-binding (Fab) and antibody tail (Fc) regions of IgG were characterized by Rodney Porter. Together, these scientists deduced the structure and complete amino acid sequence of IgG, a feat for which they were jointly awarded the 1972 Nobel Prize in Physiology or Medicine. The Fv fragment was prepared and characterized by David Givol. While most of these early studies focused on IgM and IgG, other immunoglobulin isotypes were identified in the 1960s: Thomas Tomasi discovered secretory antibody (IgA); David S. Rowe and John L. Fahey discovered IgD; and Kimishige Ishizaka and Teruko Ishizaka discovered IgE and showed it was a class of antibodies involved in allergic reactions. In a landmark series of experiments beginning in 1976, Susumu Tonegawa showed that genetic material can rearrange itself to form the vast array of available antibodies. Medical applications Disease diagnosis Detection of particular antibodies is a very common form of medical diagnostics, and applications such as serology depend on these methods. For example, in biochemical assays for disease diagnosis, a titer of antibodies directed against Epstein-Barr virus or Lyme disease is estimated from the blood. If those antibodies are not present, either the person is not infected or the infection occurred a very long time ago, and the B cells generating these specific antibodies have naturally decayed. In clinical immunology, levels of individual classes of immunoglobulins are measured by nephelometry (or turbidimetry) to characterize the antibody profile of patient. Elevations in different classes of immunoglobulins are sometimes useful in determining the cause of liver damage in patients for whom the diagnosis is unclear. For example, elevated IgA indicates alcoholic cirrhosis, elevated IgM indicates viral hepatitis and primary biliary cirrhosis, while IgG is elevated in viral hepatitis, autoimmune hepatitis and cirrhosis. Autoimmune disorders can often be traced to antibodies that bind the body's own epitopes; many can be detected through blood tests. Antibodies directed against red blood cell surface antigens in immune mediated hemolytic anemia are detected with the Coombs test. The Coombs test is also used for antibody screening in blood transfusion preparation and also for antibody screening in antenatal women. Practically, several immunodiagnostic methods based on detection of complex antigen-antibody are used to diagnose infectious diseases, for example ELISA, immunofluorescence, Western blot, immunodiffusion, immunoelectrophoresis, and magnetic immunoassay. Antibodies raised against human chorionic gonadotropin are used in over the counter pregnancy tests. New dioxaborolane chemistry enables radioactive fluoride (18F) labeling of antibodies, which allows for positron emission tomography (PET) imaging of cancer. Disease therapy Targeted monoclonal antibody therapy is employed to treat diseases such as rheumatoid arthritis, multiple sclerosis, psoriasis, and many forms of cancer including non-Hodgkin's lymphoma, colorectal cancer, head and neck cancer and breast cancer. Some immune deficiencies, such as X-linked agammaglobulinemia and hypogammaglobulinemia, result in partial or complete lack of antibodies. These diseases are often treated by inducing a short-term form of immunity called passive immunity. Passive immunity is achieved through the transfer of ready-made antibodies in the form of human or animal serum, pooled immunoglobulin or monoclonal antibodies, into the affected individual. Prenatal therapy Rh factor, also known as Rh D antigen, is an antigen found on red blood cells; individuals that are Rh-positive (Rh+) have this antigen on their red blood cells and individuals that are Rh-negative (Rh–) do not. During normal childbirth, delivery trauma or complications during pregnancy, blood from a fetus can enter the mother's system. In the case of an Rh-incompatible mother and child, consequential blood mixing may sensitize an Rh- mother to the Rh antigen on the blood cells of the Rh+ child, putting the remainder of the pregnancy, and any subsequent pregnancies, at risk for hemolytic disease of the newborn. Rho(D) immune globulin antibodies are specific for human RhD antigen. Anti-RhD antibodies are administered as part of a prenatal treatment regimen to prevent sensitization that may occur when a Rh-negative mother has a Rh-positive fetus. Treatment of a mother with Anti-RhD antibodies prior to and immediately after trauma and delivery destroys Rh antigen in the mother's system from the fetus. This occurs before the antigen can stimulate maternal B cells to "remember" Rh antigen by generating memory B cells. Therefore, her humoral immune system will not make anti-Rh antibodies, and will not attack the Rh antigens of the current or subsequent babies. Rho(D) Immune Globulin treatment prevents sensitization that can lead to Rh disease, but does not prevent or treat the underlying disease itself. Research applications Specific antibodies are produced by injecting an antigen into a mammal, such as a mouse, rat, rabbit, goat, sheep, or horse for large quantities of antibody. Blood isolated from these animals contains polyclonal antibodies—multiple antibodies that bind to the same antigen—in the serum, which can now be called antiserum. Antigens are also injected into chickens for generation of polyclonal antibodies in egg yolk. To obtain antibody that is specific for a single epitope of an antigen, antibody-secreting lymphocytes are isolated from the animal and immortalized by fusing them with a cancer cell line. The fused cells are called hybridomas, and will continually grow and secrete antibody in culture. Single hybridoma cells are isolated by dilution cloning to generate cell clones that all produce the same antibody; these antibodies are called monoclonal antibodies. Polyclonal and monoclonal antibodies are often purified using Protein A/G or antigen-affinity chromatography. In research, purified antibodies are used in many applications. Antibodies for research applications can be found directly from antibody suppliers, or through use of a specialist search engine. Research antibodies are most commonly used to identify and locate intracellular and extracellular proteins. Antibodies are used in flow cytometry to differentiate cell types by the proteins they express; different types of cells express different combinations of cluster of differentiation molecules on their surface, and produce different intracellular and secretable proteins. They are also used in immunoprecipitation to separate proteins and anything bound to them (co-immunoprecipitation) from other molecules in a cell lysate, in Western blot analyses to identify proteins separated by electrophoresis, and in immunohistochemistry or immunofluorescence to examine protein expression in tissue sections or to locate proteins within cells with the assistance of a microscope. Proteins can also be detected and quantified with antibodies, using ELISA and ELISpot techniques. Antibodies used in research are some of the most powerful, yet most problematic reagents with a tremendous number of factors that must be controlled in any experiment including cross reactivity, or the antibody recognizing multiple epitopes and affinity, which can vary widely depending on experimental conditions such as pH, solvent, state of tissue etc. Multiple attempts have been made to improve both the way that researchers validate antibodies and ways in which they report on antibodies. Researchers using antibodies in their work need to record them correctly in order to allow their research to be reproducible (and therefore tested, and qualified by other researchers). Less than half of research antibodies referenced in academic papers can be easily identified. Papers published in F1000 in 2014 and 2015 provide researchers with a guide for reporting research antibody use. The RRID paper, is co-published in 4 journals that implemented the RRIDs Standard for research resource citation, which draws data from the antibodyregistry.org as the source of antibody identifiers (see also group at Force11). Antibody regions can be used to further biomedical research by acting as a guide for drugs to reach their target. Several application involve using bacterial plasmids to tag plasmids with the Fc region of the antibody such as pFUSE-Fc plasmid. Regulations Production and testing Traditionally, most antibodies are produced by hybridoma cell lines through immortalization of antibody-producing cells by chemically induced fusion with myeloma cells. In some cases, additional fusions with other lines have created "triomas" and "quadromas". The manufacturing process should be appropriately described and validated. Validation studies should at least include: The demonstration that the process is able to produce in good quality (the process should be validated) The efficiency of the antibody purification (all impurities and virus must be eliminated) The characterization of purified antibody (physicochemical characterization, immunological properties, biological activities, contaminants, ...) Determination of the virus clearance studies Before clinical trials Product safety testing: Sterility (bacteria and fungi), in vitro and in vivo testing for adventitious viruses, murine retrovirus testing..., product safety data needed before the initiation of feasibility trials in serious or immediately life-threatening conditions, it serves to evaluate dangerous potential of the product. Feasibility testing: These are pilot studies whose objectives include, among others, early characterization of safety and initial proof of concept in a small specific patient population (in vitro or in vivo testing). Preclinical studies Testing cross-reactivity of antibody: to highlight unwanted interactions (toxicity) of antibodies with previously characterized tissues. This study can be performed in vitro (reactivity of the antibody or immunoconjugate should be determined with a quick-frozen adult tissues) or in vivo (with appropriates animal models). Preclinical pharmacology and toxicity testing: preclinical safety testing of antibody is designed to identify possible toxicity in humans, to estimate the likelihood and severity of potential adverse events in humans, and to identify a safe starting dose and dose escalation, when possible. Animal toxicity studies: Acute toxicity testing, repeat-dose toxicity testing, long-term toxicity testing Pharmacokinetics and pharmacodynamics testing: Use for determinate clinical dosages, antibody activities, evaluation of the potential clinical effects Structure prediction and computational antibody design The importance of antibodies in health care and the biotechnology industry demands knowledge of their structures at high resolution. This information is used for protein engineering, modifying the antigen binding affinity, and identifying an epitope, of a given antibody. X-ray crystallography is one commonly used method for determining antibody structures. However, crystallizing an antibody is often laborious and time-consuming. Computational approaches provide a cheaper and faster alternative to crystallography, but their results are more equivocal, since they do not produce empirical structures. Online web servers such as Web Antibody Modeling (WAM) and Prediction of Immunoglobulin Structure (PIGS) enables computational modeling of antibody variable regions. Rosetta Antibody is a novel antibody FV region structure prediction server, which incorporates sophisticated techniques to minimize CDR loops and optimize the relative orientation of the light and heavy chains, as well as homology models that predict successful docking of antibodies with their unique antigen. However, describing an antibody's binding site using only one single static structure limits the understanding and characterization of the antibody's function and properties. To improve antibody structure prediction and to take the strongly correlated CDR loop and interface movements into account, antibody paratopes should be described as interconverting states in solution with varying probabilities. The ability to describe the antibody through binding affinity to the antigen is supplemented by information on antibody structure and amino acid sequences for the purpose of patent claims. Several methods have been presented for computational design of antibodies based on the structural bioinformatics studies of antibody CDRs. There are a variety of methods used to sequence an antibody including Edman degradation, cDNA, etc.; albeit one of the most common modern uses for peptide/protein identification is liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). High volume antibody sequencing methods require computational approaches for the data analysis, including de novo sequencing directly from tandem mass spectra and database search methods that use existing protein sequence databases. Many versions of shotgun protein sequencing are able to increase the coverage by utilizing CID/HCD/ETD fragmentation methods and other techniques, and they have achieved substantial progress in attempt to fully sequence proteins, especially antibodies. Other methods have assumed the existence of similar proteins, a known genome sequence, or combined top-down and bottom up approaches. Current technologies have the ability to assemble protein sequences with high accuracy by integrating de novo sequencing peptides, intensity, and positional confidence scores from database and homology searches. Antibody mimetic Antibody mimetics are organic compounds, like antibodies, that can specifically bind antigens. They consist of artificial peptides or proteins, or aptamer-based nucleic acid molecules with a molar mass of about 3 to 20 kDa. Antibody fragments, such as Fab and nanobodies are not considered as antibody mimetics. Common advantages over antibodies are better solubility, tissue penetration, stability towards heat and enzymes, and comparatively low production costs. Antibody mimetics have being developed and commercialized as research, diagnostic and therapeutic agents. Binding antibody unit BAU (binding antibody unit, often as BAU/mL) is a measurement unit defined by the WHO for the comparison of assays detecting the same class of immunoglobulins with the same specificity.

Aston Martin Lagonda Global Holdings PLC is a British manufacturer of luxury sports cars and grand tourers. Its predecessor was founded in 1913 by Lionel Martin and Robert Bamford. Steered from 1947 by David Brown, it became associated with expensive grand touring cars in the 1950s and 1960s, and with the fictional character James Bond following his use of a DB5 model in the 1964 film Goldfinger. Their sports cars are regarded as a British cultural icon. Aston Martin has held a Royal Warrant as purveyor of motorcars to Charles III since 1982, and has over 160 car dealerships in 53 countries, making it a global automobile brand. The company is traded on the London Stock Exchange and is a constituent of the FTSE 250 Index. In 2003 it received the Queen's Award for Enterprise for outstanding contribution to international trade. The company has survived seven bankruptcies throughout its history. The headquarters and main production of its sports cars and grand tourers are in a facility in Gaydon, Warwickshire, England, on the former site of RAF Gaydon, adjacent to the Jaguar Land Rover Gaydon Centre. The old facility in Newport Pagnell, Buckinghamshire is the present home of the Aston Martin Works classic car department, which focuses on heritage sales, service, spares and restoration operations. The factory in St Athan, Wales features three converted 'super-hangars' from MOD St Athan, and serves as the production site of Aston Martin's first-ever SUV, the DBX. Aston Martin plans on building electric vehicles on both its Gaydon and St Athan factories by 2025. Aston Martin has been involved in motorsport at various points in its history, mainly in sports car racing, and also in Formula One. The Aston Martin brand is increasingly being used, mostly through licensing, on other products including a submarine, real estate development, and aircraft. History Founding Aston Martin was founded in 1913 by Lionel Martin and Robert Bamford. The two had joined forces as Bamford & Martin the previous year to sell cars made by Singer from premises in Callow Street, London where they also serviced GWK and Calthorpe vehicles. Martin raced specials at Aston Hill near Aston Clinton, and the pair decided to make their own vehicles. The first car to be named Aston Martin was created by Martin by fitting a four-cylinder Coventry-Simplex engine to the chassis of a 1908 Isotta Fraschini. They acquired premises at Henniker Mews in Kensington and produced their first car in March 1915. Production could not start because of the outbreak of the First World War, when Martin joined the Admiralty and Bamford joined the Army Service Corps. 1918–1939: Interwar years After the war they found new premises at Abingdon Road, Kensington and designed a new car. Bamford left in 1920 and Bamford & Martin was revitalised with funding from Count Louis Zborowski. In 1922, Bamford & Martin produced cars to compete in the French Grand Prix, which went on to set world speed and endurance records at Brooklands. Three works Team Cars with 16-valve twin cam engines were built for racing and record-breaking: chassis number 1914, later developed as the Green Pea; chassis number 1915, the Razor Blade record car; and chassis number 1916, later developed as the Halford Special. Approximately 55 cars were built for sale in two configurations; long chassis and short chassis. Bamford & Martin went bankrupt in 1924 and was bought by Dorothea, Lady Charnwood, who put her son John Benson on the board. Bamford & Martin got into financial difficulty again in 1925 and Martin was forced to sell the company (Bamford had already left). Later that year, Bill Renwick, Augustus (Bert) Bertelli and investors including Lady Charnwood took control of the business. They renamed it Aston Martin Motors and moved it to the former Whitehead Aircraft Limited Hanworth works in Feltham. Renwick and Bertelli had been in partnership some years and had developed an overhead-cam four-cylinder engine using Renwick's patented combustion chamber design, which they had tested in an Enfield-Allday chassis. The only "Renwick and Bertelli" motor car made, it was known as "Buzzbox" and still survives. The pair had planned to sell their engine to motor manufacturers, but having heard that Aston Martin was no longer in production realised they could capitalise on its reputation to jump-start the production of a completely new car. Between 1926 and 1937 Bertelli was both technical director and designer of all new Aston Martins, since known as "Bertelli cars". They included the 1½-litre "T-type", "International", "Le Mans", "MKII" and its racing derivative, the "Ulster", and the 2-litre 15/98 and its racing derivative, the "Speed Model". Most were open two-seater sports cars bodied by Bert Bertelli's brother Enrico (Harry), with a small number of long-chassis four-seater tourers, dropheads and saloons also produced. Bertelli was a competent driver keen to race his cars, one of few owner/manufacturer/drivers. The "LM" team cars were very successful in national and international motor racing including at Le Mans. Financial problems reappeared in 1932. Aston Martin was rescued for a year by Lance Prideaux Brune before passing it on to Sir Arthur Sutherland. In 1936, Aston Martin decided to concentrate on road cars, producing just 700 until World War II halted work. Production shifted to aircraft components during the war. 1947–1972: David Brown In 1947, old-established (1860) privately owned Huddersfield gear and machine tools manufacturer David Brown Limited bought Aston Martin, putting it under control of its Tractor Group. David Brown became Aston Martin's latest saviour. He also acquired Lagonda, without its factory, for its 2.6-litre W. O. Bentley-designed engine. Lagonda moved operations to Newport Pagnell and shared engines, resources and workshops. Aston Martin began to build the classic "DB" series of cars. In April 1950, they announced planned production of their Le Mans prototype to be called the DB2, followed by the DB2/4 in 1953, the DB2/4 MkII in 1955, the DB Mark III in 1957 and the Italian-styled 3.7 L DB4 in 1958. While these models helped Aston Martin establish a good racing pedigree, the DB4 stood out and yielded the famous DB5 in 1963. Aston stayed true to its grand touring style with the DB6 (1965–70), and DBS (1967–1972). The six-cylinder engines of these cars from 1954 up to 1965 were designed by Tadek Marek. 1972–1975: William Willson Aston Martin was often financially troubled. In 1972, David Brown paid off all its debts, said to be £5 million or more, and handed it for £101 to Company Developments, a Birmingham-based investment bank consortium chaired by accountant William Willson. More detail on this period may be read at Willson's biography. The worldwide recession, lack of working capital and the difficulties of developing an engine to meet California's exhaust emission requirements – it stopped the company's US sales – again pulled Aston Martin into receivership at the end of 1974. The company had employed 460 workers when the manufacturing plant closed. 1975–1981: Sprague and Curtis The receiver sold the business in April 1975 for £1.05 million to North American businessman Peter Sprague of National Semiconductor, Toronto hotelier George Minden, and Jeremy Turner, a London businessman, who insisted to reporters that Aston Martin remained a British controlled business. Sprague later claimed he had fallen in love with the factory, not the cars, the workforce's craftsmanship dedication and intelligence. At this point, he and Minden had brought in investor Alan Curtis, a British office property developer, together with George Flather, a retired Sheffield steel magnate. Six months later, in September 1975, the factory – shut down the previous December – re-opened under its new owner as Aston Martin Lagonda Limited with 100 employees, and planned to lift staff to 250 by the end of 1975. In January 1976, AML revealed that it now held orders for 150 cars for the US, 100 for other markets and another 80 from a Japanese importing agency. At the Geneva Motor Show, Fred Hartley, managing director and sales director for 13 years before that, announced he had resigned over "differences in marketing policy". The new owners pushed Aston Martin into modernising its line, introducing the V8 Vantage in 1977, the convertible Volante in 1978, and the one-off Bulldog styled by William Towns in 1980. Towns also styled the futuristic new Lagonda saloon, based on the V8 model. Curtis, who had a 42% stake in Aston Martin, also brought about a change in direction from the usual customers who were Aston Martin fans, to successful young married businessmen. Prices had been increased by 25%. There was speculation that AML was about to buy Italian automobile manufacturer Lamborghini. At the end of the 1970s, there was widespread debate about running MG into the Aston Martin consortium. 85 Conservative MPs formed themselves into a pressure group to get British Leyland to release their grip and hand it over. CH Industrials plc (car components) bought a 10% share in AML. But in July 1980, blaming a recession, AML cut back their workforce of 450 by more than 20%, making those people redundant. 1981–1987: Victor Gauntlett In January 1981, there having been no satisfactory revival partners, Alan Curtis and Peter Sprague announced they had never intended to maintain a long-term financial stake in Aston Martin Lagonda and it was to be sold to Pace Petroleum's Victor Gauntlett. Sprague and Curtis pointed out that under their ownership AML finances had improved to where an offer for MG might have been feasible. Gauntlett bought a 12.5% stake in Aston Martin for £500,000 via Pace Petroleum in 1980, with Tim Hearley of CH Industrials taking a similar share. Pace and CHI took over as joint 50/50 owners at the beginning of 1981, with Gauntlett as executive chairman. Gauntlett also led the sales team, and after some development and publicity when the Lagonda became the world's fastest four-seater production car, was able to sell the car in Oman, Kuwait, and Qatar. In 1982, Aston Martin was granted a Royal Warrant of Appointment by the Prince of Wales. Understanding that it would take some time to develop new Aston Martin products, they created an engineering service subsidiary to develop automotive products for other companies. It was decided to use a trade name of Salmons & Son, their in-house coachbuilder, Tickford, which Aston Martin had bought in 1955. Tickford's name had been long associated with expensive high-quality carriages and cars along with their folding roofs. New products included a Tickford Austin Metro, a Tickford Ford Capri and even Tickford train interiors, particularly on the Jaguar XJS. Pace continued sponsoring racing events, and now sponsored all Aston Martin Owners Club events, taking a Tickford-engined Nimrod Group C car owned by AMOC President Viscount Downe, which came third in the Manufacturers Championship in both 1982 and 1983. It also finished seventh in the 1982 24 Hours of Le Mans race. However, sales of production cars were now at an all-time low of 30 cars produced in 1982. As trading became tighter in the petroleum market, and Aston Martin was requiring more time and money, Gauntlett agreed to sell Hays/Pace to the Kuwait Investment Office in September 1983. As Aston Martin required greater investment, he also agreed to sell his share holding to American importer and Greek shipping tycoon Peter Livanos, who invested via his joint venture with Nick and John Papanicolaou, ALL Inc. Gauntlett remained chairman of AML, 55% of the stake was owned by ALL, with Tickford a 50/50 venture between ALL and CHI. The uneasy relationship was ended when ALL exercised options to buy a larger share in AML; CHI's residual shares were exchanged for CHI's complete ownership of Tickford, which retained the development of existing Aston Martin projects. In 1984, Papanicolaou's Titan shipping business was in trouble so Livanos's father George bought out the Papanicolaou's shares in ALL, while Gauntlett again became a shareholder with a 25% holding in AML. The deal valued Aston Martin/AML at £2 million, the year it built its 10,000th car. Although as a result Aston Martin had to make 60 members of the workforce redundant, Gauntlett bought a stake in Italian styling house Zagato, and resurrected its collaboration with Aston Martin. In 1986, Gauntlett negotiated the return of the fictional British secret agent James Bond to Aston Martin. Cubby Broccoli had chosen to recast the character using actor Timothy Dalton, in an attempt to re-root the Bond-brand back to a more Sean Connery-like feel. Gauntlett supplied his personal pre-production Vantage for use in the filming of The Living Daylights, and sold a Volante to Broccoli for use at his home in America. Gauntlett turned down the role of a KGB colonel in the film, however: "I would have loved to have done it but really could not afford the time." 1987–2007: Ford Motor Company As Aston Martin needed funds to survive in the long term, Ford bought a 75% stake in the company in 1987, and bought the rest later. In May of that year, Victor Gauntlett and Prince Michael of Kent were staying at the home of Contessa Maggi, the wife of the founder of the original Mille Miglia, while watching the revival event. Another house guest was Walter Hayes, vice-president of Ford of Europe. Despite problems over the previous acquisition of AC Cars, Hayes saw the potential of the brand and the discussion resulted in Ford taking a share holding in September 1987. In 1988, having produced some 5,000 cars in 20 years, a revived economy and successful sales of limited edition Vantage, and 52 Volante Zagato coupés at £86,000 each; Aston Martin finally retired the ancient V8 and introduced the Virage range. Although Gauntlett was contractually to stay as chairman for two years, his racing interests took the company back into sports car racing in 1989 with limited European success. However, with engine rule changes for the 1990 season and the launch of the new Volante model, Ford provided the limited supply of Cosworth engines to the Jaguar cars racing team. As the entry-level DB7 would require a large engineering input, Ford agreed to take full control of Aston Martin, and Gauntlett handed over Aston Martin's chairmanship to Hayes in 1991. In 1992, the high-performance variant of the Virage called the Vantage was announced, and the following year Aston Martin renewed the DB range by announcing the DB7. By 1993, Ford had fully acquired the company after having built a stake in 1987. Ford placed Aston Martin in the Premier Automotive Group, invested in new manufacturing and ramped up production. In 1994, Ford opened a new factory at Banbury Road in Bloxham to manufacture the DB7. In 1995, Aston Martin produced a record 700 cars. Until the Ford era, cars had been produced by hand coachbuilding craft methods, such as the English wheel. During the mid 1990s, the Special Projects Group, a secretive unit with Works Service at Newport Pagnell, created an array of special coach-built vehicles for the Brunei royal family. In 1998, the 2,000th DB7 was built, and in 2002, the 6,000th, exceeding production of all of the previous DB series models. The DB7 range was revamped by the addition of more powerful V12 Vantage models in 1999, and in 2001, Aston Martin introduced the V12-engined flagship model called the Vanquish which succeeded the aging Virage (now called the V8 Coupé). At the North American International Auto Show in Detroit, Michigan in 2003, Aston Martin introduced the V8 Vantage concept car. Expected to have few changes before its introduction in 2005, the Vantage brought back the classic V8 engine to allow Aston Martin to compete in a larger market. 2003 also saw the opening of the Gaydon factory, the first purpose-built factory in Aston Martin's history. The facility is situated on a site of a former RAF V Bomber airbase, with an front building for offices, meeting rooms and customer reception, and a production building. Also introduced in 2003 was the DB9 coupé, which replaced the ten-year-old DB7. A convertible version of the DB9, the DB9 Volante, was introduced at the 2004 Detroit auto show. In October 2004, Aston Martin set up the dedicated Aston Martin Engine Plant (AMEP) within the Ford Germany Niehl, Cologne plant. With the capacity to produce up to 5,000 engines a year by 100 specially trained personnel, like traditional Aston Martin engine production from Newport Pagnell, assembly of each unit was entrusted to a single technician from a pool of 30, with V8 and V12 variants assembled in under 20 hours. By bringing engine production back to within Aston Martin, the promise was that Aston Martin would be able to produce small runs of higher performance variants' engines. This expanded engine capacity allowed the entry-level V8 Vantage sports car to enter production at the Gaydon factory in 2006, joining the DB9 and DB9 Volante. In December 2003, Aston Martin announced it would return to motor racing in 2005. A new division was created, called Aston Martin Racing, which became responsible, together with Prodrive, for the design, development, and management of the DBR9 program. The DBR9 competes in the GT class in sports car races, including the world-famous 24 Hours of Le Mans. In 2006, an internal audit led Ford to consider divesting itself of parts of its Premier Automotive Group. After suggestions of selling Jaguar Cars, Land Rover, or Volvo Cars were weighed, Ford announced in August 2006 it had engaged UBS AG to sell all or part of Aston Martin at auction. 2007–2018: Private Limited Company On 12 March 2007, a consortium led by Prodrive chairman David Richards purchased Aston Martin for £475 million (US$848 million). The group included American investment banker John Sinders and two Kuwaiti companies namely Investment Dar and Adeem Investment. Prodrive had no financial involvement in the deal. Ford kept a stake in Aston Martin valued at £40 million (US$70 million). To demonstrate the V8 Vantage's durability across hazardous terrain and promote the car in China, the first east–west crossing of the Asian Highway was undertaken between June and August 2007. A pair of Britons drove from Tokyo to Istanbul before joining the European motorway network for another to London. The promotion was so successful Aston Martin opened dealerships in Shanghai and Beijing within three months. On 19 July 2007, the Newport Pagnell plant rolled out the last of nearly 13,000 cars made there since 1955, a Vanquish S. The Tickford Street facility was converted and became the home of the Aston Martin Works classic car department which focuses on heritage sales, service, spares and restoration operations. UK production was subsequently concentrated on the facility in Gaydon on the former RAF V Bomber airbase. In March 2008, Aston Martin announced a partnership with Magna Steyr to outsource manufacture of over 2,000 cars annually to Graz, Austria, reassuringly stating: "The continuing growth and success of Aston Martin is based upon Gaydon as the focal point and heart of the business, with the design and engineering of all Aston Martin products continuing to be carried out there." More dealers in Europe and the new pair in China brought the total to 120 in 28 countries. On 1 September 2008, Aston Martin announced the revival of the Lagonda marque, proposing a concept car to be shown in 2009 to coincide with the brand's 100th anniversary. The first production cars were slated for production in 2012. In December 2008, Aston Martin announced it would cut its workforce from 1,850 to 1,250 due to the economic recession. The first four-door Rapide grand tourers rolled out of the Magna Steyr factory in Graz, Austria in 2010. The contract manufacturer provides dedicated facilities to ensure compliance with the exacting standards of Aston Martin and other marques, including Mercedes-Benz. Then CEO of the company, Ulrich Bez had publicly speculated about outsourcing all of Aston Martin's operations with the exception of marketing. In September 2011, it was announced that production of the Rapide would be returned to Gaydon in the second half of 2012, restoring all of the company's automobile manufacture there. Italian private equity fund Investindustrial signed a deal on 6 December 2012 to buy a 37.5% stake in Aston Martin, investing £150 million as a capital increase. This was confirmed by Aston Martin in a press release on 7 December 2012. David Richards left Aston Martin in 2013, returning to concentrate on Prodrive. In April 2013, it was reported that Bez would be leaving his role as the chief executive officer to take up a more ambassadorial position. On 2 September 2014, Aston Martin announced it had appointed the Nissan executive Andy Palmer as the new CEO with Bez retaining a position as non-executive chairman. As sales had been declining from 2015, Aston Martin sought new customers (particularly wealthy female buyers) with introducing concept cars like the DBX SUV along with track focused cars like the Vulcan. According to Palmer, the troubles started when sales of the DB9 failed to generate sufficient fund to develop next-generation models which led to a downward spiral of declining sales and profitability. Palmer outlined that the company plans to develop two new platforms, add a crossover, refresh its supercar lineup and leverage its technology alliance with Daimler as part of its six-year plan to make the 100-year-old British brand consistently profitable. He stated, "In the first century we went bankrupt seven times. The second century is about making sure that is not the case." In preparation for its next-generation of sports cars, the company invested £20 million ($33.4 million) to expand its manufacturing plant in Gaydon. The expansion at the Gaydon plant includes a new chassis and pilot build facility, as well as an extension of the parts and logistics storage area, and new offices. In total, Aston Martin will add approximately to the plant. In 2014, Aston Martin suffered a pre-tax loss of £72 million, almost triple of the amount of 2013 selling 3,500 cars during the year, well below the 7,300 cars sold in 2007 and 4,200 sold in 2013 respectively. In March 2014, Aston Martin issued "payment in kind" notes of US$165 million, at 10.25% interest, in addition to the £304 million of senior secured notes at 9.25% issued in 2011. Aston Martin also had to secure an additional investment of £200 million from its shareholders to fund development of new models. It was reported that Aston Martin's pre-tax losses for 2016 increased by 27% to £162.8 million, the sixth year it continued to suffer a loss. In 2016, the company selected a site in St Athan, South Wales for its new factory. The Welsh facility was unanimously chosen by Aston's board despite fierce competition from other locations as far afield as the Americas, Eastern Europe, the Middle East, Europe, as well as two other sites in the UK, believed to be Bridgend and Birmingham. The facility featured three existing ‘super-hangars’ of MOD St Athan. Construction work of converting the hangars commenced in April 2017. Aston Martin returned to profit in 2017 after selling over 5,000 cars. The company made a pre-tax profit of £87 million compared with a £163 million loss in 2016. 2017 also marked the return of production of the Newport Pagnell facility ten years after it originally ceased. 2013–present: Partnership with Mercedes-Benz Group In December 2013, Aston Martin signed a deal with Mercedes-Benz Group (at the time known as Daimler) to supply the next generation of Aston Martin cars with Mercedes-AMG engines. Mercedes-AMG also was to supply Aston Martin with electrical systems. This technical partnership was intended to support Aston Martin's launch of a new generation of models that would incorporate new technology and engines. In exchange, Mercedes will get as much as 5% equity in Aston Martin and a non-voting seat on its board. The first model to sport the Mercedes-Benz technology was the DB11, announced at the 86th Geneva Motor Show in March 2016. It featured Mercedes-Benz electronics for the entertainment, navigation and other systems. It was also the first model to use Mercedes-AMG V8 engines. In October 2020, Mercedes confirmed it will increase its holding "in stages" from 5% to 20%. In return, Aston Martin will have access to Mercedes-Benz hybrid and electric drivetrain technologies for its future models. 2018–present: Listed on the London Stock Exchange After "completing a turnaround for the once perennially loss-making company that could now be valued at up to 5 billion pounds ($6.4 billion)," and now reporting a full-year pre-tax profit of £87 million (compared with a £163 million loss in 2016) Aston Martin in August 2018 announced plans to float the company at the London Stock Exchange as Aston Martin Lagonda Global Holdings plc. The company was the subject of an initial public offering on the London Stock Exchange on 3 October 2018. In the same year, Aston Martin opened a new vehicle dynamics test and development centre at Silverstone's Stowe Circuit alongside a new HQ in London. In June 2019, the company opened its new factory in St Athan for the production of its first-ever SUV the DBX. The factory was finally completed and officially opened on 6 December 2019. When full production begins in the second quarter of 2020, around 600 people will be employed at the factory, rising to 750 when peak production is reached. On 31 January 2020 it was announced that Canadian billionaire and investor Lawrence Stroll was leading a consortium, Yew Tree Overseas Limited, who will pay £182 million in return for 16.7% stake in the company. The re-structuring includes a £318 million cash infusion through a new rights issue, generating a total of £500 million for the company. Stroll will also be named as chairman, replacing Penny Hughes. Swiss pharmaceutical magnate Ernesto Bertarelli and Mercedes-AMG Petronas F1 team principal and CEO Toto Wolff have also joined the consortium, acquiring 3.4% and 4.8% stakes, respectively. In March 2020, Stroll increased his stake in the company to 25%. On 26 May 2020, Aston Martin announced that Andy Palmer had stepped down as CEO. Tobias Moers of Mercedes-AMG will succeed him starting 1 August, with Keith Stanton as interim chief operating officer. In June 2020, the company announced that it cut out 500 jobs as a result of the poor sales, an outcome of the COVID-19 pandemic lockdown. In March 2021, executive chairman Lawrence Stroll stated that the company plans on building electric vehicles by 2025. In May 2022, Aston Martin named 76-year old Amedeo Felisa as the new chief executive officer, replacing Tobias Moers. Roberto Fedeli was also announced as the new chief technical officer. In November 2020, a communications agency called Clarendon Communications published a report comparing the environmental impact of various powertrain options for cars. After the report received coverage from The Sunday Times and other publications, it emerged that the company had been set up in February that year and was registered under the name of Rebecca Stephens – the wife of James Stephens, who is the government affairs director of Aston Martin Lagonda. Citing a study by Polestar, the report stated that electric vehicles would need to be driven before they would have lower overall emissions than a petrol car. This statement was disputed by electric vehicle researcher Auke Hoekstra, who argued that the report underestimated the emissions from combustion engine vehicles and did not consider the emissions from creating petrol. According to him, a typical EV would need to drive 16,000–18,000 miles (25,700–30,000 km) in order to offset the emissions from manufacture. Bosch and a number of other companies were also involved with the report. In July 2022, Saudi Arabia's Public Investment Fund (PIF) will take a stake in the company through a £78 million equity placing as well as a £575 million separate rights issue, giving it two board seats in the company. After the rights issue, the Saudi fund will have a 16.7% stake in Aston Martin, behind the 18.3% holding by Stroll's Yew Tree consortium while the Mercedes-Benz Group will own 9.7%. In September 2022, Chinese automaker Geely acquired a 7.6% stake in the company. In December 2022, Stroll and the Yew Tree consortium increased their stake in the company to 28.29%. In May 2023, Geely increased its stake to 17%, becoming the third-largest shareholder after the Yew Tree consortium and the Saudi Arabia Public Investment Fund. In June 2023, Aston Martin signed an agreement with Lucid Motors after selecting it to help supply electric motors, powertrains, and battery systems for its upcoming range of fully electric cars. In return, Aston Martin will make cash payments and issue a 3.7percent stake in its company to Lucid, worth $232million in total. In October 2023, Aston Martin announced that it would compete in the FIA World Endurance Championship and IMSA SportsCar Championship in 2025. Notable events In August 2017, a 1956 Aston Martin DBR1/1 sold at a Sotheby's auction at the Pebble Beach, California Concours d'Elegance for US$22,550,000, which made it the most expensive British car ever sold at an auction, according to Sotheby's. The car had previously been driven by Carroll Shelby and Stirling Moss. Other notable Aston Martin models sold at an auction include a 1962 Aston Martin DB4 GT Zagato for US$14,300,000 in New York in 2015, and a 1963 Aston Martin DP215 for US$21,455,000 in August 2018.

A female advisory panel was established to adapt the design of the cars to the taste of women. In September 2016, a 37-foot-long Aston Martin speedboat was unveiled called the Aston Martin AM37 powerboat. In September 2017, Aston Martin announced that they had partnered with submarine building company Triton Submarines to build a submarine called Project Neptune. Aston Martin has collaborated with the luxury clothing company Hackett London to deliver items of clothing. In November 2017, Aston Martin unveiled a special limited edition bicycle after collaborating with bicycle manufacturer Storck. Aston Martin and global property developer G&G Business Developments are currently building a 66-storey luxury condominium tower called Aston Martin Residences at 300 Biscayne Boulevard Way in Miami, Florida, which is set for completion in 2021. In July 2018, Aston Martin unveiled the Volante Vision Concept, a luxury concept aircraft with vertical take-off and landing capabilities. Also in July, a Lego version of James Bond's DB5 car was put on sale and an Aston Martin-branded watch was released in collaboration with TAG Heuer. In October 2018, Aston Martin announced it was opening a design and brand studio in Shanghai. Motorsport Aston Martin is currently associated with two different racing organisations. The Aston Martin Formula One team which competes in the Formula One Championship and Aston Martin Racing which currently competes in the FIA World Endurance Championship. Both racing organisations use the Aston Martin brand, but are not directly owned by Aston Martin. The Aston Martin Formula One team is owned by major Aston Martin shareholder Lawrence Stroll and operated by his company AMR GP, while Aston Martin Racing is operated by racing company Prodrive as part of a partnership with Aston Martin. Formula One Aston Martin participated as a Formula One constructor in and entering six races over the two years but failing to score any points. In January 2020, it was announced that the Racing Point F1 Team is due to be rebranded as Aston Martin for the 2021 season, as a result of a funding investment led by Racing Point owner Lawrence Stroll. As part of the rebrand, the team switched their racing colour of BWT pink to a modern iteration of Aston Martin's British racing green. The Aston Martin AMR21 was unveiled in March 2021 and became Aston Martin's first Formula One car after a 61-year absence from the sport.

Andhra Pradesh (, abbr. AP) is a state in the southern coastal region of India. It is the seventh-largest state with an area of and the tenth-most populous state with 49,577,103 inhabitants. It has shared borders with Chhattisgarh, Odisha, Karnataka, Tamil Nadu, Telangana and the Bay of Bengal. It has the second-longest coastline in India at about . After existence as Andhra State and unified Andhra Pradesh, the state took its present form on 2 June 2014, when the new state of Telangana was formed through bifurcation. Amaravati is the capital of the state, with the largest city being Visakhapatnam. Water sharing disputes and asset division with Telangana are not yet resolved. Telugu, one of the classical languages of India used by the majority of people, is the first official language. As per the 8th century BCE Rigvedic text Aitareya Brahmana, the Andhras left North India off the banks of the Yamuna river and migrated to South India. In the third century BCE, Andhra was a vassal kingdom of Ashoka of the Mauryan Empire. After his death, it became powerful and extended its empire to the whole Maratha country and beyond under the rule of the Satavahana dynasty. After that, the major rulers included the Pallavas, Eastern Chalukyas, Kakatiyas, Vijayanagara Empire, Qutb Shahi dynasty, Nizam dynasty, East India Company, and British Raj. The Eastern Ghats are a major dividing line separating coastal plains and peneplains. The coastal plains are part of Coastal Andhra. These are mostly delta regions formed by the Krishna, Godavari, and Penna rivers. Peneplains are part of Rayaaseema. 60% of the population is engaged in agriculture and related activities. Rice is the state's major food crop and staple food. The state contributes 10% of total fish production and over 70% of shrimp production in India. Industry sectors such as food products, non-metallic minerals, textiles, and pharmaceuticals are the top employment providers. The automotive sector accounts for 10% of India's auto exports. The state has about one-third of India's limestone reserves, large deposits of baryte and galaxy granite, and reserves of oil and natural gas. Satish Dhawan Space Centre (SDSC), known as Sriharikota Range (SHAR), at the barrier island of Sriharikota in Tirupati district, is the satellite launching station of India. Some of the unique products from the state are Banaganapalle mangoes, Bandar laddu, Kondaplli toys, Tirupati laddu, and saris made in Dharmavaram and Machilipatnam. Kuchipudi is the official dance form. Many composers of Carnatic music, like Annamacharya, Kshetrayya, and Tyagaraja, were from this region. The Tirumala Venkateswara temple near Tirupati is the most visited Hindu religious place in the world. The state is home to a variety of other pilgrimage centres and natural attractions. Etymology According to the Sanskrit text Aitareya Brahmana (800–500 BCE), a group of people named Andhras left North India off the banks of the Yamuna and settled in South India. The Satavahanas were mentioned by the names Andhra, Andhrara-jateeya, and Andhrabhrtya in the Puranic literature. They did not refer to themselves as Andhra in any of their coins or inscriptions; it is possible that they were termed as Andhras because of their ethnicity or because their territory included the Andhra region. History Early and medieval history The Assaka mahajanapada, one of the sixteen Vedic mahajanapadas, included Andhra Pradesh, Maharashtra, and Telangana. Archaeological evidence from places such as Bhattiprolu, Amaravati, Dharanikota, and Vaddamanu suggests that the Andhra region was part of the Mauryan empire. Amaravati might have been a regional centre under Mauryan rule. After the death of Emperor Ashoka, Mauryan rule weakened around 200 BCE and was replaced by several smaller kingdoms in the Andhra region. One of the earliest examples of the Brahmi script, the progenitor of several scripts, including Telugu, comes from Bhattiprolu, where the script was used on an urn containing the relics of Buddha. The Satavahana dynasty dominated the Deccan plateau from the 1st century BCE to the 3rd century CE. It had trade relations with the Roman Empire. The later Satavahanas made Dharanikota, near Amaravati, their capital. According to the Buddhists, Nagarjuna, the philosopher of Mahayana, lived in this region. The Andhra Ikshvakus, with their capital at Vijayapuri, succeeded the Satavahanas in the Krishna River valley in the latter half of the 2nd century. The Salankayanas were an ancient dynasty that ruled the Andhra region between Godavari and Krishna with their capital at Vengi (modern Pedavegi) from 300 to 440 CE. Telugu Cholas ruled present-day Rayalaseema from the fifth to the eleventh centuries from Cuddapa and Jammalamadugu. The Telugu inscription of Erikal Mutturaju Dhananjaya Varma, known as Erragudipadu , was engraved in 575 CE in the present Kadapa district. It is the earliest written record in Telugu. The Vishnukundinas were the first dynasty in the fifth and sixth centuries to hold sway over most of Andhra Pradesh, Kalinga, and parts of Telangana. The Eastern Chalukyas of Vengi, whose dynasty lasted for around five hundred years from the 7th century until 1130 CE, eventually merged with the Chola dynasty. They continued to rule under the protection of the Chola dynasty until 1189 CE. At the request of King Rajaraja Narendra, Nannaya, considered the first Telugu poet, took up the translation of the Mahabharata into Telugu in 1025 CE. Kakatiyas ruled this region and Telangana for nearly two hundred years between the 12th and 14th centuries. They were defeated by the Delhi Sultanate. Musunuri Nayaks and Bahamani Sultanate took over when Delhi Sultanate became weak. The Reddi kingdom ruled parts of this region in the early 14th century. They constructed Kondaveedu Fort and Kondapalli Fort. After their rule, Gajpathis and Bahmani sultans ruled this region in succession before this region, along with most of present-day Andhra Pradesh, became part of the Vijayanagar empire. The Vijayanagara empire originated on the Deccan plateau in the early 14th century. It was established in 1336 by Harihara Raya I and his brother Bukka Raya I of the Sangama dynasty, who served as treasury officers of the Kakatiyas of Warangal. During their rule, the Pemmasani Nayaks controlled parts of Andhra Pradesh and had large mercenary armies that were the vanguard of the empire in the 16th century. The empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu, Tamil, and Sanskrit, while Carnatic music evolved into its current form. The Lepakshi group of monuments built during this period have mural paintings of the Vijayanagara kings, Dravidian art, and inscriptions. These are put on the tentative list of the UNESCO World Heritage Committee. Modern history Following the defeat of the Vijayanagara empire, the Qutb Shahi dynasty held sway over Andhra Pradesh. This region passed under the rule of the Nizams under the Mughal Empire. Soon, Nizam established himself as the sovereign ruler. In 1611, an English trading post by the name of "East India Company" was established in Masulipatinam on India's east coast. In the early nineteenth century, Northern Circars was ceded to the British East India Company and became part of its Madras Presidency. Eventually, this region emerged as the Coastal Andhra region, the northern parts of which were later known as Uttarandhra. Later, the Nizam ceded five territories to the British, which eventually became the Rayalaseema region. The local chieftains, known as Poligars, revolted in 1800 against the company's rule, which was suppressed by the company. Raja Viziaram Raz (Vijayaram Raj) established a sovereign kingdom by claiming independence from the Kingdom of Jeypore in 1711. It formed alliances with the French and British East India Companies to conquer the neighbouring principalities of Bobbili, Kurupam, Paralakhemundi, and the kingdom of Jeypore. It fell out with the British and, as a result, was attacked and defeated in the battle of Padmanabham. It was annexed as a tributary estate like other principalities and remained so until their accession to the Indian Union in 1949. Following the Indian rebellion of 1857, the British crown ruled this region, until India became independent in 1947. The No Tax Campaign in Chirala and Perala in 1919, led by Duggirala Gopalakrishnayya, the Rampa Revolt led by Alluri Sitarama Raju in 1921, and the Salt Satyagraha in Dendulur in 1930 are some of the protests against British rule. Tanguturi Prakasam was arrested and jailed for more than three years for participating in the Quit India movement of 1942. He served as prime minister of the Madras presidency in 1946–47. Dowleswaram Barrage, built in 1850 by Arthur Cotton, brought unused lands in the Godavari river basin into cultivation and transformed the economy of the region. Charles Philip Brown did pioneering work in transforming Telugu to the print era and introduced Vemana poems to English readers. Kandukuri Veeresalingam is considered the father of the Telugu Renaissance Movement, as he encouraged the education of women and the remarriage of widows and fought against child marriage and the dowry system. Gurajada Apparao, a pioneering playwright who used spoken dialect, wrote the play Kanyasulkam in 1892. It is considered the greatest play in the Telugu language. Post-independence In an effort to gain an independent state based on linguistic identity and to protect the interests of the Telugu-speaking people of Madras State, Potti Sreeramulu fasted to death in 1952. The Telugu-speaking area of Andhra State was carved out of Madras State on 1 October 1953, with Kurnool as its capital city. Tanguturi Prakasam became the first chief minister. On the basis of the Gentlemen's Agreement of 1956, the States Reorganisation Act created Andhra Pradesh by merging the neighbouring Telugu-speaking areas of the Hyderabad State with Hyderabad as the capital on 1 November 1956. The Indian National Congress (INC) ruled the state from 1956 to 1982. Neelam Sanjiva Reddy became the first chief minister. Among Congress chief ministers, P. V. Narasimha Rao is known for implementing land reforms and land ceiling acts and securing reservation for lower castes in politics. In 1983, the Telugu Desam Party (TDP) won the state elections, and N. T. Rama Rao became the chief minister of the state for the first time after launching his party just nine months earlier. This broke the long-time single-party monopoly enjoyed by the INC. He transformed the sub-district administration by forming mandals in place of earlier taluks, removing hereditary village heads, and appointing non-hereditary village revenue assistants. Nara Chandrababu Naidu, Rao's son-in-law, came to power in 1995 with the backing of a majority of the MLAs. He introduced e-governance by launching e-Seva centres in 2001 for paperless and speedy delivery of government services. He is credited with transforming Hyderabad into an IT hub by providing incentives for tech companies to set up centres. In 2004, Congress returned to power with a new chief ministerial face, YS Rajashekara Reddy, better known as YSR. The main emphasis during Reddy's tenure was on social welfare schemes such as free electricity for farmers, health insurance, tuition fee reimbursement for the poor, and the national rural employment guarantee scheme. He was elected chief minister again but was killed in a helicopter crash that occurred in September 2009. During its 58 years as a unified state, the state weathered separatist movements from Telangana (1969) and Andhra (1972) successfully. A new party called Telangana Rashtra Samithi, formed in April 2001 by Kalvakuntla Chandrashekar Rao (KCR), reignited the Telanganga movement. When the central government decided to initiate the process to form an independent Telangana in December 2009, Samaikyandhra movement to keep the state united took shape. The agitations continued for nearly 5 years, with the Telangana side harping on the marginalisation of food culture, language, and unequal economic development and the Samaikyandhra movement focusing on the shared culture, language, customs, and historical unity of Telugu-speaking regions. The Andhra Pradesh Reorganisation Act bill was passed by the parliament of India for the formation of the Telangana state, comprising ten districts, despite opposition by the state legislature. The new state of Telangana came into existence on 2 June 2014 after approval from the president of India, with the residual state continuing as Andhra Pradesh. In the final elections held in the unified state in 2014, the TDP got a mandate in its favour, defeating its nearest rival, the YSR Congress Party, a breakaway faction of the Congress founded by Y. S. Jagan Mohan Reddy, son of former Chief Minister Y. S. Rajasekhara Reddy. N. Chandrababu Naidu, the chief of the TDP, became the chief minister on 8 June 2014. In 2017, the government of Andhra Pradesh began operating from its new greenfield capital, Amaravati, for which 33,000 acres were acquired from farmers through an innovative land pooling scheme. Interstate issues with Telangana relating to the division of assets of public sector institutions and organisations of the united state and the division of river waters are not yet resolved.

Jagan Mohan Reddy, withdrew the act when the High Court hearing reached the final stage. The chief minister said that his government would bring a better and more complete bill. The protesters under the banner of Amaravati Parirakshana Samithi (APS) and the Joint Action Committee (JAC) of Amaravati received support from all the political parties barring the ruling YCP when they held their long marches across the state seeking support for their agitation. On 3 March 2022, the High Court ruled that the government could not abandon the development of Amaravati as the capital city after farmers parted with 33,000 acres of land against the agreement with Andhra Pradesh Capital Region Development Authority (APCRDA) to develop it as the capital city and ₹15,000 crore was sunk in it over development expenditure. It asked the government to develop Amaravati within six months. When the government appealed to the Supreme Court, it got a stay on the judgement regarding developing the city within six months. The Supreme Court is set to hear it in December 2023, following its decision on 11 July 2023. Interstate disputes Assets division with Telangana There are 91 institutions under schedule IX with assets of ₹1.42 lakh crore, 142 institutions under schedule X with assets of ₹24,018.53 crore, and another 12 institutions not mentioned in the act with assets of ₹1,759 crore, which are to be split between Andhra Pradesh and Telangana following the bifurcation. An expert committee headed by Sheela Bhide gave a recommendation for bifurcation of 89 out of the 91 schedule IX institutions. Telangana selectively accepted the recommendations, while Andhra Pradesh is asking for their acceptance in total. The division of the RTC headquarters and the Deccan Infrastructure and Landholdings Limited (DIL) with huge land parcels has become contentious. Despite several meetings of the trilateral dispute resolution committees, no progress was made. The Andhra Pradesh government filed a suit in the Supreme Court. Krishna river water sharing dispute Andhra Pradesh and Telangana continue to dispute the water share of the Krishna River. In 1969, the Bachawat tribunal for the allocation of water shares among the riparian states allocated 811 tmcft of water to Andhra Pradesh. The Andhra Pradesh government of that time split it in a 512:299 tmcft ratio between Andhra Pradesh (including the basin area of Rayalaseema) and Telangana, respectively. It was based on the utilisation facilities established at that time. Though the tribunal recommended the use of the Tungabhadra Dam (a part of the Krishna Basin) to provide water to the drought-prone Mahabubnagar area of Telangana, this was not implemented. The bifurcation act advised the formation of the Krishna River Management Board (KRMB) and the Godavari River Management Board (GRMB) for resolving disputes between the new states. In 2015, the two states agreed to share water in the 66:34 (AP:Telangana) ratio as an interim arrangement in a meeting with the central water ministry, which is to be reviewed every year. This practice continued without further review. Telangana filed a suit in the Supreme Court for a 70% share. Following the assurance of the formation of a tribunal to resolve the issue, Telangana withdrew its suit. The centre has yet to form the tribunal. Godavari water sharing dispute Andhra Pradesh got 1172.78 tmcft of Godavari water. Telangana is utilising 433 tmcft for its completed projects, while Andhra Pradesh's share is 739 tmcft. The Andhra Pradesh government has opposed Telangana submitting a detailed project report for additional utilisation through new or upgraded projects such as Kaleswaram, Tupakulagudem, Sitarama, Mukteswaram, and Modikunta lift irrigation projects. Five villages near Bhadrachalam The 1.50-metre increase in the height of the Polavaram coffer dam to 44 metres raised the suspicion that it led to flooding of Bhadrachalam and nearby villages in Telangana along the Godavari river in 2022. Three mandals that were originally part of Andhra State were transferred back to Andhra Pradesh, excluding Bhadrachalam town, to support the Polavaram project, as those areas are likely to be submerged. Telangana would like to take back five villages on the river banks for ease of movement of its government machinery to provide rehabilitation support to its other villages beyond them, to which the Andhra Pradesh government is objecting.

Power Thermal, hydel and renewable power plants supply power to the state. The installed capacity share of the state in the public sector generating stations was 7,245 MW. Private sector installed capacity was 9,370 MW, which includes independent power producer capacity of 1,961 MW. The total installed capacity was 16,615 MW. Peak power demand for the state in 2021–22 was 12,032 MW and per capita consumption was 1,285 kilowatt hours. The energy consumed is 68972 million units. Healthcare The government is spending 7.3% of the state budget on healthcare, compared to an average of 4 to 4.5 per cent overall in the country. The 108 service provides fast emergency management services by shifting patients to a nearby healthcare facility. The 104 service provides health care services at the doorstep of villages through mobile medical units that visit at least once a month. All the poor families are covered by the free state health insurance scheme called Arogyasri up to a limit of . The services are provided in government and private hospitals under the network. During 2014–2018, though the nominal mean claim amount of Arogyasri beneficiaries went up significantly, it decreased after accounting for inflation. Mortality rates have significantly decreased, which indicates better outcomes are being achieved at a lower cost. Education Primary and secondary school education is imparted by government-aided and private schools, managed and regulated by the School Education Department of the state. There are urban, rural, and residential schools. As per the child info and school information report (2018–19), there were a total of students enrolled in schools. students have appeared for the April 2023 Secondary School Certificate (SSC) exam in the regular stream. The overall pass percentage was 72.26%, with 100% in 933 schools. In March–April 2023, 379,758 students appeared for intermediate second-year examinations. 272,001 candidates, amounting to 71%, were declared passed. The state initiated education reforms in 2020 by creating six types of schools: satellite foundation schools (pre-primary), foundational schools (pre-primary – class II), foundational school plus (pre-primary – class V), pre-high school (class III – class VII/VIII), high school (class III – class X), and high school plus (class III – class XII). The transition to English-medium education in all government schools started in the academic year 2020–2021 and is expected to reach completion by 2024–25. 1000 government schools are affiliated to the CBSE in the years 2022–23 as an initial step, and the bilingual text book scheme was adopted to ease the transition. The state government is going ahead with the English medium based on the parents survey despite protests and court cases. The state initiative is being funded in part by a loan from the World Bank to the tune of $250 million over 2021–2026 through the "Supporting Andhra's Learning Transformation" (SALT) project to improve the learning outcomes of children up to class II level. There were 510 industrial training institutes (ITI) in the year 2020–21 in Andhra Pradesh, with 82 under government management and 417 under private management.

Some of the GI products are Banaganapalle mangoes, Bandar laddu, Kondapalli toys, Tirupati laddu, and saris made in Dharmavaram and Machilipatnam. Handicrafts Machilipatnam and Srikalahasti Kalamkari are the two unique textile art forms practised in India. There are other notable handicrafts present in the state, like the soft limestone idol carvings of Durgi. Etikoppaka in Visakhapatnam district is notable for its lac industry, which produces lacquered wooden toys. Literature Nannayya, Tikkana, and Yerrapragada form the trinity who translated the Sanskrit epic Mahabharata into Telugu. Nannayya wrote the first treatise on Telugu grammar, called Andhra Shabda Chintamani in Sanskrit. Pothana translated Sri Bhagavatam into Telugu as Andhra Maha Bhagavatamu. Vemana was an Indian philosopher. He wrote Telugu poems using simple language and native idioms on a variety of subjects, including yoga, wisdom, and morality. Potuluri Veerabrahmendhra swami, a clairvoyant and social reformer, wrote Kalagnanam, a book of predictions written in the 16th century. Telugu literature after Kandukuri Veeresalingam is termed Adhunika Telugu Sahityam (modern Telugu literature). He is known as Gadya Tikkana and was the author of the Telugu social novel Satyavati Charitam. Viswanatha Satyanarayana was conferred the Jnanpith Award. Sri Sri brought new forms of expressionism into Telugu literature. Festivals Sankranti is the major harvest festival celebrated across the state. It is celebrated for four days in the second week of January. On Bhogi, the day before Makara Sankranti, people throw old items into bonfires. Children are showered with jujube as a symbol of protection from evil. Sweet meats made of rice flour and sesame seeds called Arisalu are enjoyed. Next day, women and young girls make elaborate geometric patterns called Rangoli before the entrance to the house and decorate them with flowers. Children fly kites. On the subsequent two days, Kanuma and Mukkanuma, people feed cattle and offer prayers for a good harvest. The first day of Telugu New Year Ugadi which occurs during March/April is also a special festival with preparation and sharing of pickle (pachhadi) made from raw mangoes, neem flowers, pepper powder, jaggery and tamarind. Tasting this pickle which is mix of different tastes teaches the importance of taking positive/negative life experiences in one's stride. Celebrations end with the recitation of the coming year's astrological predictions called Panchanga sravanam. Vijaya Dasami known commonly as Dussera and Deepavali, the festival of lights are other major Hindu festivals. Eid is celebrated with special prayers. Rottela Panduga is celebrated at Bara Shaheed Dargah in Nellore with participation across religious lines. Dance, music, and cinema Kuchipudi, the cultural dance recognised as the official dance form of the state of Andhra Pradesh, originated in the village of Kuchipudi in Krishna district. Many composers of Carnatic music like Annamacharya, Kshetrayya, Tyagaraja, and Bhadrachala Ramadas were of Telugu descent. Modern Carnatic music composers and singers like Ghantasala and M. Balamuralikrishna are of Telugu descent. The Telugu film industry hosted many music composers and playback singers, such as S. P. Balasubrahmanyam, P. Susheela, S. Janaki, and P. B. Sreenivas. Folk songs are very important and popular in the many rural areas of the state. Forms such as the Burra katha and Poli are still performed today. Harikathaa Kalakshepam (or Harikatha) involves the narration of a story, intermingled with various songs relating to the story. Harikatha was originated in Andhra Pradesh. Burra katha is an oral storytelling technique in which the topic is either a Hindu mythological story or a contemporary social issue. Rangasthalam is an Indian theatre in the Telugu language, based predominantly in Andhra Pradesh. Gurajada Apparao wrote the play Kanyasulkam in 1892, which is often considered the greatest play in the Telugu language. C. Pullaiah is cited as the father of the Telugu theatre movement. Andhra Pradesh State Film, Television & Theatre Development Corporation offers incentives to promote the industry. The government is asking the film industry to make Vizag its hub. The Telugu film industry (known as "Tollywood"), which produces 300 films annually, is primarily based in Hyderabad, though several films are shot in Vizag. Film producer D. Ramanaidu holds a Guinness record for the most films produced by a person. In the years 2005, 2006, and 2008, the Telugu film industry produced the largest number of films in India, exceeding the number of films produced in Bollywood. "Naatu Naatu" from the film RRR became the first song from an Indian film to win the Academy Award for Best Original Song and the Golden Globe Award for Best Original Song, as well as the first song from an Asian film to win the former. Cuisine Andhra meals are combinations of spicy, tangy, and sweet flavours. Chillies, which are abundantly produced in Andhra Pradesh, and curry leaves are used copiously in most preparations of curries and chutneys. Various types of Pappu are made using lentils in combination with tomatoes, spinach, gongura, ridge gourd, etc. Apart from curries, pulusu, a stew made using tamarind juice in combination with vegetables, sea food, chicken, mutton, etc., is popular. Pachchadi, a paste usually made with a combination of groundnuts, fried vegetables, and chillies, is a must in a meal. Pickles made using mangoes, gooseberries, lemons, etc. are enjoyed in combination with Pappu. Buttermilk and yoghurt mixed with rice and eaten towards the end of the meal soothe the body, especially after eating spicy food items earlier. Ariselu, Burelu, Laddu, and Pootharekulu are some of the sweets made for special festivals and occasions. Tourism Some of the popular religious pilgrim destinations include Tirumala Venkateswara temple at Tirupati, Srikalahasti temple, Varaha Lakshmi Narasimha temple, Simhachalam, Shahi Jamia Masjid in Adoni, Gunadala Church in Vijayawada, and Buddhist centres at Amaravati and Nagarjuna Konda. Tirumala Venkateswara temple is the world's most visited Hindu temple, with footfalls of 30,000–40,000 daily and about 75,000 on New Year's Eve. The region is home to a variety of other pilgrimage centres, such as the Pancharama Kshetras, Mallikarjuna Jyotirlinga, Kanaka Durga Temple and Kodanda Rama Temple.

Accelerated Graphics Port (AGP) is a parallel expansion card standard, designed for attaching a video card to a computer system to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards. Since 2004, AGP was progressively phased out in favor of PCI Express (PCIe), which is serial, as opposed to parallel; by mid-2008, PCI Express cards dominated the market and only a few AGP models were available, with GPU manufacturers and add-in board partners eventually dropping support for the interface in favor of PCI Express. Advantages over PCI AGP is a superset of the PCI standard, designed to overcome PCI's limitations in serving the requirements of the era's high-performance graphics cards. The primary advantage of AGP is that it doesn't share the PCI bus, providing a dedicated, point-to-point pathway between the expansion slot(s) and the motherboard chipset. The direct connection also allows for higher clock speeds. The second major change is the use of split transactions, wherein the address and data phases are separated. The card may send many address phases so the host can process them in order, avoiding any long delays caused by the bus being idle during read operations. Third, PCI bus handshaking is simplified. Unlike PCI bus transactions whose length is negotiated on a cycle-by-cycle basis using the FRAME# and STOP# signals, AGP transfers are always a multiple of 8 bytes long, with the total length included in the request. Further, rather than using the IRDY# and TRDY# signals for each word, data is transferred in blocks of four clock cycles (32 words at AGP 8× speed), and pauses are allowed only between blocks. Finally, AGP allows (mandatory only in AGP 3.0) sideband addressing, meaning that the address and data buses are separated so the address phase does not use the main address/data (AD) lines at all. This is done by adding an extra 8-bit "SideBand Address" bus over which the graphics controller can issue new AGP requests while other AGP data is flowing over the main 32 address/data (AD) lines. This results in improved overall AGP data throughput. This great improvement in memory read performance makes it practical for an AGP card to read textures directly from system RAM, while a PCI graphics card must copy it from system RAM to the card's video memory. System memory is made available using the graphics address remapping table (GART), which apportions main memory as needed for texture storage. The maximum amount of system memory available to AGP is defined as the AGP aperture. History The AGP slot first appeared on x86-compatible system boards based on Socket 7 Intel P5 Pentium and Slot 1 P6 Pentium II processors. Intel introduced AGP support with the i440LX Slot 1 chipset on August 26, 1997, and a flood of products followed from all the major system board vendors. The first Socket 7 chipsets to support AGP were the VIA Apollo VP3, SiS 5591/5592, and the ALI Aladdin V. Intel never released an AGP-equipped Socket 7 chipset. FIC demonstrated the first Socket 7 AGP system board in November 1997 as the FIC PA-2012 based on the VIA Apollo VP3 chipset, followed very quickly by the EPoX P55-VP3 also based on the VIA VP3 chipset which was first to market. Early video chipsets featuring AGP support included the Rendition Vérité V2200, 3dfx Voodoo Banshee, Nvidia RIVA 128, 3Dlabs PERMEDIA 2, Intel i740, ATI Rage series, Matrox Millennium II, and S3 ViRGE GX/2. Some early AGP boards used graphics processors built around PCI and were simply bridged to AGP. This resulted in the cards benefiting little from the new bus, with the only improvement used being the 66 MHz bus clock, with its resulting doubled bandwidth over PCI, and bus exclusivity. Intel's i740 was explicitly designed to exploit the new AGP feature set; in fact it was designed to texture only from AGP memory, making PCI versions of the board difficult to implement (local board RAM had to emulate AGP memory.) Microsoft first introduced AGP support into Windows 95 OEM Service Release 2 (OSR2 version 1111 or 950B) via the USB SUPPLEMENT to OSR2 patch. After applying the patch the Windows 95 system became Windows 95 version 4.00.950 B. The first Windows NT-based operating system to receive AGP support was Windows NT 4.0 with Service Pack 3, introduced in 1997. Linux support for AGP enhanced fast data transfers was first added in 1999 with the implementation of the AGPgart kernel module. Later use With the increasing adoption of PCIe, graphics cards manufacturers continued to produce AGP cards as the standard became obsolete. As GPUs began to be designed to connect to PCIe, an additional PCIe-to-AGP bridge-chip was required to create an AGP-compatible graphics card. The inclusion of a bridge, and the need for a separate AGP card design, incurred additional board costs. The GeForce 6600 and ATI Radeon X800 XL, released during 2004–2005, were the first bridged cards. In 2009 AGP cards from Nvidia had a ceiling of the GeForce 7 Series. In 2011 DirectX 10-capable AGP cards from AMD vendors (Club 3D, HIS, Sapphire, Jaton, Visiontek, Diamond, etc.) included the Radeon HD 2400, 3450, 3650, 3850, 4350, 4650, and 4670. The HD 5000 AGP series mentioned in the AMD Catalyst software was never available. There were many problems with the AMD Catalyst 11.2 - 11.6 AGP hotfix drivers under Windows 7 with the HD 4000 series AGP video cards; use of 10.12 or 11.1 AGP hotfix drivers is the recommended workaround. Several of the vendors listed above make available past versions of the AGP drivers. By 2010, no new motherboard chipsets supported AGP and few new motherboards had AGP slots, however some continued to be produced with older AGP-supporting chipsets. In 2016, Windows 10 version 1607 dropped support for AGP. Possible future removal of support for AGP from open source Linux kernel drivers was considered in 2020. Versions Intel released "AGP specification 1.0" in 1997. It specified 3.3 V signals and 1× and 2× speeds. Specification 2.0 documented 1.5 V signaling, which could be used at 1×, 2× and the additional 4× speed and 3.0 added 0.8 V signaling, which could be operated at 4× and 8× speeds. (1× and 2× speeds are physically possible, but were not specified.) Available versions are listed in the adjacent table. AGP version 3.5 is only publicly mentioned by Microsoft under Universal Accelerated Graphics Port (UAGP), which specifies mandatory supports of extra registers once marked optional under AGP 3.0. Upgraded registers include PCISTS, CAPPTR, NCAPID, AGPSTAT, AGPCMD, NISTAT, NICMD. New required registers include APBASELO, APBASEHI, AGPCTRL, APSIZE, NEPG, GARTLO, GARTHI. There are various physical interfaces (connectors); see the Compatibility section. Official extensions AGP Pro An official extension for cards that required more electrical power, with a longer slot with additional pins for that purpose. AGP Pro cards were usually workstation-class cards used to accelerate professional computer-aided design applications employed in the fields of architecture, machining, engineering, simulations, and similar fields. 64-bit AGP A 64-bit channel was once proposed as an optional standard for AGP 3.0 in draft documents, but it was dropped in the final version of the standard. The standard allows 64-bit transfer for AGP8× reads, writes, and fast writes; 32-bit transfer for PCI operations. Unofficial variations A number of non-standard variations of the AGP interface have been produced by manufacturers. Internal AGP interface Ultra-AGP, Ultra-AGPII It is an internal AGP interface standard used by SiS for the north bridge controllers with integrated graphics. The original version supports same bandwidth as AGP 8×, while Ultra-AGPII has maximum 3.2GB/s bandwidth. PCI-based AGP ports AGP Express Not a true AGP interface, but allows an AGP card to be connected over the legacy PCI bus on a PCI Express motherboard. It is a technology used on motherboards made by ECS, intended to allow an existing AGP card to be used in a new motherboard instead of requiring a PCIe card to be obtained (since the introduction of PCIe graphics cards few motherboards provide AGP slots). An "AGP Express" slot is basically a PCI slot (with twice the electrical power) with an AGP connector. It offers backward compatibility with AGP cards, but provides incomplete support (some AGP cards do not work with AGP Express) and reduced performance—the card is forced to use the shared PCI bus at its lower bandwidth, rather than having exclusive use of the faster AGP. AGI The ASRock Graphics Interface (AGI) is a proprietary variant of the Accelerated Graphics Port (AGP) standard. Its purpose is to provide AGP-support for ASRock motherboards that use chipsets lacking native AGP support. However, it is not fully compatible with AGP, and several video card chipsets are known not to be supported. AGX The EPoX Advanced Graphics eXtended (AGX) is another proprietary AGP variant with the same advantages and disadvantages as AGI. User manuals recommend not using AGP 8× ATI cards with AGX slots. XGP The Biostar Xtreme Graphics Port is another AGP variant, also with the same advantages and disadvantages as AGI and AGX. PCIe based AGP ports AGR The Advanced Graphics Riser is a variation of the AGP port used in some PCIe motherboards made by MSI to offer limited backwards compatibility with AGP. It is, effectively, a modified PCIe slot allowing for performance comparable to an AGP 4×/8× slot, but does not support all AGP cards; the manufacturer published a list of some cards and chipsets that work with the modified slot. Compatibility AGP cards are backward and forward compatible within limits. 1.5 V-only keyed cards will not go into 3.3 V slots and vice versa, though "Universal" cards exist which will fit into either type of slot. There are also unkeyed "Universal" slots that will accept either type of card. When an AGP Universal card is plugged-into an AGP Universal slot, only the 1.5 V portion of the card is used. Some cards, like Nvidia's GeForce 6 series (except the 6200) or ATI's Radeon X800 series, only have keys for 1.5 V to prevent them from being installed in older mainboards without 1.5 V support. Some of the last modern cards with 3.3 V support were: the Nvidia GeForce FX series (FX 5200, FX 5500, FX 5700, some FX 5800, FX 5900 and some FX 5950) certain GeForce 6 Series and 7 series (few cards were made with 3.3v support except for 6200 where 3.3v support was common) some GeForce 6200/6600/6800 and GeForce 7300/7600/7800/7900/7950 cards (really uncommon compared to their AGP 1.5v only versions) the ATI Radeon 9500/9700/9800 (R300/R350) (but not 9600/9800 (R360/RV360)). AGP Pro cards will not fit into standard slots, but standard AGP cards will work in a Pro slot. Motherboards equipped with a Universal AGP Pro slot will accept a 1.5 V or 3.3 V card in either the AGP Pro or standard AGP configuration, a Universal AGP card, or a Universal AGP Pro card. Some cards incorrectly have dual notches, and some motherboards incorrectly have fully open slots, allowing a card to be plugged into a slot that does not support the correct signaling voltage, which may damage card or motherboard. Some incorrectly designed older 3.3 V cards have the 1.5 V key. There are some proprietary systems incompatible with standard AGP; for example, Apple Power Macintosh computers with the Apple Display Connector (ADC) have an extra connector which delivers power to the attached display. Some cards designed to work with a specific CPU architecture (e.g., PC, Apple) may not work with others due to firmware issues. Mark Allen of Playtools.com made the following comments regarding Practical AGP Compatibility for AGP 3.0 and AGP 2.0: Power consumption Actual power supplied by an AGP slot depends upon the card used. The maximum current drawn from the various rails is given in the specifications for the various versions. For example, if maximum current is drawn from all supplies and all voltages are at their specified upper limits, an AGP 3.0 slot can supply up to 48.25 watts; this figure can be used to specify a power supply conservatively, but in practice a card is unlikely ever to draw more than 40 W from the slot, with many using less. AGP Pro provides additional power up to 110 W. Many AGP cards had additional power connectors to supply them with more power than the slot could provide. Protocol An AGP bus is a superset of a 66 MHz conventional PCI bus and, immediately after reset, follows the same protocol. The card must act as a PCI target, and optionally may act as a PCI master. (AGP 2.0 added a "fast writes" extension which allows PCI writes from the motherboard to the card to transfer data at higher speed.) After the card is initialized using PCI transactions, AGP transactions are permitted. For these, the card is always the AGP master and the motherboard is always the AGP target. The card queues multiple requests which correspond to the PCI address phase, and the motherboard schedules the corresponding data phases later. An important part of initialization is telling the card the maximum number of outstanding AGP requests which may be queued at a given time. AGP requests are similar to PCI memory read and write requests, but use a different encoding on command lines C/BE[3:0] and are always 8-byte aligned; their starting address and length are always multiples of 8 bytes (64 bits). The three low-order bits of the address are used instead to communicate the length of the request. Whenever the PCI GNT# signal is asserted, granting the bus to the card, three additional status bits ST[2:0] indicate the type of transfer to be performed next. If the bits are 0xx, a previously queued AGP transaction's data is to be transferred; if the three bits are 111, the card may begin a PCI transaction or (if sideband addressing is not in use) queue a request in-band using PIPE#. AGP command codes Like PCI, each AGP transaction begins with an address phase, communicating an address and 4-bit command code. The possible commands are different from PCI, however: 000p Read Read 8×(AD[2:0]+1) = 8, 16, 24, ..., 64 bytes. The least significant bit p is 0 for low-priority, 1 for high. 001x (reserved): 010p Write Write 8×(AD[2:0]+1) = 8–64 bytes. 011x (reserved): 100p Long read Read 32×(AD[2:0]+1) = 32, 64, 96, ..., 256 bytes. This is the same as a read request, but the length is multiplied by four. 1010 Flush Force previously written data to memory, for synchronization. This acts as a low-priority read, taking a queue slot and returning 8 bytes of random data to indicate completion. The address and length supplied with this command are ignored. 1011 (reserved): 1100 Fence This acts as a memory fence, requiring that all earlier AGP requests complete before any following requests. Ordinarily, for increased performance, AGP uses a very weak consistency model, and allows a later write to pass an earlier read. (E.g. after sending "write 1, write 2, read, write 3, write 4" requests, all to the same address, the read may return any value from 2 to 4. Only returning 1 is forbidden, as writes must complete before following reads.) This operation does not require any queue slots. 1101 Dual address cycle When making a request to an address above 232, this is used to indicate that a second address cycle will follow with additional address bits. This operates like a regular PCI dual address cycle; it is accompanied by the low-order 32 bits of the address (and the length), and the following cycle includes the high 32 address bits and the desired command. The two cycles make one request, and take only one slot in the request queue. This request code is not used with side-band addressing. 111x (reserved): AGP 3.0 dropped high-priority requests and the long read commands, as they were little used. It also mandated side-band addressing, thus dropping the dual address cycle, leaving only four request types: low-priority read (0000), low-priority write (0100), flush (1010) and fence (1100). In-band AGP requests using PIPE# To queue a request in-band, the card must request the bus using the standard PCI REQ# signal, and receive GNT# plus bus status ST[2:0] equal to 111. Then, instead of asserting FRAME# to begin a PCI transaction, the card asserts the PIPE# signal while driving the AGP command, address, and length on the C/BE[3:0], AD[31:3] and AD[2:0] lines, respectively. (If the address is 64 bits, a dual address cycle similar to PCI is used.) For every cycle that PIPE# is asserted, the card sends another request without waiting for acknowledgement from the motherboard, up to the configured maximum queue depth. The last cycle is marked by deasserting REQ#, and PIPE# is deasserted on the following idle cycle. Side-band AGP requests using SBA[7:0] If side-band addressing is supported and configured, the PIPE# signal is not used. (And the signal is re-used for another purpose in the AGP 3.0 protocol, which requires side-band addressing.) Instead, requests are broken into 16-bit pieces which are sent as two bytes across the SBA bus. There is no need for the card to ask permission from the motherboard; a new request may be sent at any time as long as the number of outstanding requests is within the configured maximum queue depth. The possible values are: 0aaa aaaa aaaa alll Queue a request with the given low-order address bits A[14:3] and length 8×(L[2:0]+1). The command and high-order bits are as previously specified. Any number of requests may be queued by sending only this pattern, as long as the command and higher address bits remain the same. 10cc ccra aaaa aaaa Use command C[3:0] and address bits A[23:15] for future requests. (Bit R is reserved.) This does not queue a request, but sets values that will be used in all future queued requests. 110r aaaa aaaa aaaa Use address bits A[35:24] for future requests. 1110 aaaa aaaa aaaa Use address bits A[47:36] for future requests. 1111 0xxx, 1111 10xx, 1111 110x Reserved, do not use. 1111 1110 Synchronization pattern used when starting the SBA bus after an idle period. 1111 1111 No operation; no request. At AGP 1× speed, this may be sent as a single byte and a following 16-bit side-band request started one cycle later. At AGP 2× and higher speeds, all side-band requests, including this NOP, are 16 bits long. Sideband address bytes are sent at the same rate as data transfers, up to 8× the 66 MHz basic bus clock. Sideband addressing has the advantage that it mostly eliminates the need for turnaround cycles on the AD bus between transfers, in the usual case when read operations greatly outnumber writes. AGP responses While asserting GNT#, the motherboard may instead indicate via the ST bits that a data phase for a queued request will be performed next. There are four queues: two priorities (low- and high-priority) for each of reads and writes, and each is processed in order. Obviously, the motherboard will attempt to complete high-priority requests first, but there is no limit on the number of low-priority responses which may be delivered while the high-priority request is processed. For each cycle when the GNT# is asserted and the status bits have the value 00p, a read response of the indicated priority is scheduled to be returned. At the next available opportunity (typically the next clock cycle), the motherboard will assert TRDY# (target ready) and begin transferring the response to the oldest request in the indicated read queue. (Other PCI bus signals like FRAME#, DEVSEL# and IRDY# remain deasserted.) Up to four clock cycles worth of data (16 bytes at AGP 1× or 128 bytes at AGP 8×) are transferred without waiting for acknowledgement from the card. If the response is longer than that, both the card and motherboard must indicate their ability to continue on the third cycle by asserting IRDY# (initiator ready) and TRDY#, respectively. If either one does not, wait states will be inserted until two cycles after they both do. (The value of IRDY# and TRDY# at other times is irrelevant and they are usually deasserted.) The C/BE# byte enable lines may be ignored during read responses, but are held asserted (all bytes valid) by the motherboard. The card may also assert the RBF# (read buffer full) signal to indicate that it is temporarily unable to receive more low-priority read responses. The motherboard will refrain from scheduling any more low-priority read responses. The card must still be able to receive the end of the current response, and the first four-cycle block of the following one if scheduled, plus any high-priority responses it has requested. For each cycle when GNT# is asserted and the status bits have the value 01p, write data is scheduled to be sent across the bus. At the next available opportunity (typically the next clock cycle), the card will assert IRDY# (initiator ready) and begin transferring the data portion of the oldest request in the indicated write queue. If the data is longer than four clock cycles, the motherboard will indicate its ability to continue by asserting TRDY# on the third cycle. Unlike reads, there is no provision for the card to delay the write; if it didn't have the data ready to send, it shouldn't have queued the request. The C/BE# lines are used with write data, and may be used by the card to select which bytes should be written to memory. The multiplier in AGP 2×, 4× and 8× indicates the number of data transfers across the bus during each 66 MHz clock cycle. Such transfers use source synchronous clocking with a "strobe" signal (AD_STB[0], AD_STB[1], and SB_STB) generated by the data source. AGP 4× adds complementary strobe signals. Because AGP transactions may be as short as two transfers, at AGP 4× and 8× speeds it is possible for a request to complete in the middle of a clock cycle. In such a case, the cycle is padded with dummy data transfers (with the C/BE# byte enable lines held deasserted). Connector pinout The AGP connector contains almost all PCI signals, plus several additions. The connector has 66 contacts on each side, although 4 are removed for each keying notch. Pin 1 is closest to the I/O bracket, and the B and A sides are as in the table, looking down at the motherboard connector. Contacts are spaced at 1 mm intervals, however they are arranged in two staggered vertical rows so that there is 2 mm space between pins in each row. Odd-numbered A-side contacts, and even-numbered B-side contacts are in the lower row (1.0 to 3.5 mm from the card edge). The others are in the upper row (3.7 to 6.0 mm from the card edge). PCI signals omitted are: The −12 V supply The third and fourth interrupt requests (INTC#, INTD#) The JTAG pins (TRST#, TCK, TMS, TDI, TDO) The SMBus pins (SMBCLK, SMBDAT) The IDSEL pin; an AGP card connects AD[16] to IDSEL internally The 64-bit extension (REQ64#, ACK64#) and 66 MHz (M66EN) pins The LOCK# pin for locked transaction support Signals added are: Data strobes AD_STB[1:0] (and AD_STB[1:0]# in AGP 2.0) The sideband address bus SBA[7:0] and SB_STB (and SB_STB# in AGP 2.0) The ST[2:0] status signals USB+ and USB− (and OVERCNT# in AGP 2.0) The PIPE# signal (removed in AGP 3.0 for 0.8 V signaling) The RBF# signal The TYPEDET#, Vregcg and Vreggc pins (AGP 2.0 for 1.5V signaling) The DBI_HI and DBI_LO signals (AGP 3.0 for 0.8 V signaling only) The GC_DET# and MB_DET# pins (AGP 3.0 for 0.8V signaling) The WBF# signal (AGP 3.0 fast write extension) See also List of device bandwidths Serial Digital Video Out for ADD DVI adapter cards AGP Inline Memory Module Notes References External links Archived AGP Implementors Forum AGP specifications: 1.0, 2.0, 3.0, Pro 1.0, Pro 1.1a AGP Compatibility For Sticklers AGP pinout AGP expansion slots AGP compatibility (with pictures) PCI Specifications Documents contains AGP specs.

Aalen () is a former Free Imperial City located in the eastern part of the German state of Baden-Württemberg, about east of Stuttgart and north of Ulm. It is the seat of the Ostalbkreis district and is its largest town. It is also the largest town in the Ostwürttemberg region. Since 1956, Aalen has had the status of Große Kreisstadt (major district town). It is noted for its many half-timbered houses constructed from the 16th century through the 18th century. With an area of 146.63 km2, Aalen is ranked 7th in Baden-Württemberg and 2nd within the Government Region of Stuttgart, after Stuttgart. With a population of about 66,000, Aalen is the 15th most-populated settlement in Baden-Württemberg. Geography Situation Aalen is situated on the upper reaches of the river Kocher, at the foot of the Swabian Jura which lies to the south and south-east, and close to the hilly landscapes of the Ellwangen Hills to the north and the Welland to the north-west. The west of Aalen's territory is on the foreland of the eastern Swabian Jura, and the north and north-west is on the Swabian-Franconian Forest, both being part of the Swabian Keuper-Lias Plains. The south-west is part of the Albuch, the east is part of the Härtsfeld, these two both being parts of the Swabian Jura. The Kocher enters the town's territory from Oberkochen to the south, crosses the district of Unterkochen, then enters the town centre, where the Aal flows into it. The Aal is a small river located only within the town's territory. Next, the Kocher crosses the district of Wasseralfingen, then leaves the town for Hüttlingen. Rivers originating near Aalen are the Rems (near Essingen, west of Aalen) and the Jagst (near Unterschneidheim, east of Aalen), both being tributaries of the Neckar, just like the Kocher. The elevation in the centre of the market square is relative to Normalhöhennull. The territory's lowest point is at the Lein river near Rodamsdörfle, the highest point is the Grünberg's peak near Unterkochen at . Geology Aalen's territory ranges over all lithostratigraphic groups of the South German Jurassic: Aalen's south and the Flexner massif are on top of the White Jurassic, the town centre is on the Brown Jurassic, and a part of Wasseralfingen is on the Black Jurassic. As a result, the town advertises itself as a "Geologist's Mecca". Most parts of the territory are on the Opalinuston-Formation (Opalinum Clay Formation) of the Aalenian subdivision of the Jurassic Period, which is named after Aalen. On the Sandberg, the Schnaitberg and the Schradenberg hills, all in the west of Aalen, the Eisensandstein (Iron Sandstone) formation emerges to the surface. On the other hills of the city, sands (Goldshöfer Sande), gravel and residual rubble prevail. The historic centre of Aalen and the other areas in the Kocher valley are founded completely on holocenic floodplain loam (Auelehm) and riverbed gravel that have filled in the valley. Most parts of Dewangen and Fachsenfeld are founded on formations of Jurensismergel (Jurensis Marl), Posidonienschiefer (cf. Posidonia Shale), Amaltheenton (Amalthean Clay), Numismalismergel (Numismalis Marl) and Obtususton (Obtusus Clay, named after Asteroceras obtusum ammonites) moving from south to north, all belonging to the Jurassic and being rich in fossils. They are at last followed by the Trossingen Formation already belonging to the Late Triassic. Until 1939 iron ore was mined on the Braunenberg hill. (see Tiefer Stollen section). Extent of the borough The maximum extent of the town's territory amounts to in a north–south dimension and in an east–west dimension. The area is , which includes 42.2% agriculturally used area and 37.7% of forest. 11.5% are built up or vacant, 6.4% is used by traffic infrastructure. Sporting and recreation grounds and parks comprise 1% , other areas 1.1% . Boroughs Aalen's territory consists of the town centre (Kernstadt) and the municipalities merged from between 1938 (Unterrombach) and 1975 (Wasseralfingen, see mergings section). The municipalities merged in the course of the latest municipal reform of the 1970s are also called Stadtbezirke (quarters or districts), and are Ortschaften ("settlements") in terms of Baden-Württemberg's Gemeindeordnung (municipal code), which means, each of them has its own council elected by its respective residents (Ortschaftsrat) and is presided by a spokesperson (Ortsvorsteher). The town centre itself and the merged former municipalities consist of numerous villages (Teilorte), mostly separated by open ground from each other and having their own independent and long-standing history. Some however have been created as planned communities, which were given proper names, but no well-defined borders. List of villages: Spatial planning Aalen forms a Mittelzentrum ("medium-level centre") within the Ostwürttemberg region. Its designated catchment area includes the following municipalities of the central and eastern Ostalbkreis district: Abtsgmünd, Bopfingen, Essingen, Hüttlingen, Kirchheim am Ries, Lauchheim, Neresheim, Oberkochen, Riesbürg and Westhausen, and is interwoven with the catchment area of Nördlingen, situated in Bavaria, east of Aalen. Climate As Aalen's territory sprawls on escarpments of the Swabian Jura, on the Albuch and the Härtsfeld landscapes, and its elevation has a range of , the climate varies from district to district. The weather station the following data originate from is located between the town centre and Wasseralfingen at about and has been in operation since 1991. The sunshine duration is about 1800 hours per year, which averages 4.93 hours per day. So Aalen is above the German average of 1550 hours per year. However, with 167 days of precipitation, Aalen's region also ranks above the German average of 138. The annual rainfall is , about the average within Baden-Württemberg. The annual mean temperature is . Here Aalen ranks above the German average of and the Baden-Württemberg average of . History Civic history First settlements Numerous remains of early civilization have been found in the area. Tools made of flint and traces of Mesolithic human settlement dated between the 8th and 5th millennium BC were found on several sites on the margins of the Kocher and Jagst valleys. On the Schloßbaufeld plateau (appr. ), situated behind Kocherburg castle near Unterkochen, a hill-top settlement was found, with the core being dated to the Bronze Age. In the Appenwang forest near Wasseralfingen, in Goldshöfe, and in Ebnat, tumuli of the Hallstatt culture were found. In Aalen and Wasseralfingen, gold and silver coins left by the Celts were found. The Celts were responsible for the fortifications in the Schloßbaufeld settlement consisting of sectional embankments and a stone wall. Also, Near Heisenberg (Wasseralfingen), a Celtic nemeton has been identified; however, it is no longer readily apparent. Roman era After abandoning the Alb Limes (a limes generally following the ridgeline of the Swabian Jura) around 150 AD, Aalen's territory became part of the Roman Empire, in direct vicinity of the then newly erected Rhaetian Limes. The Romans erected a castrum to house the cavalry unit Ala II Flavia milliaria; its remains are known today as Kastell Aalen ("Aalen Roman fort"). The site is west of today's town centre at the bottom of the Schillerhöhe hill. With about 1,000 horsemen and nearly as many grooms, it was the largest fort of auxiliaries along the Rhaetian Limes. There were Civilian settlements adjacent along the south and the east. Around 260 AD, the Romans gave up the fort as they withdrew their presence in unoccupied Germania back to the Rhine and Danube rivers, and the Alamanni took over the region. Based on 3rd- and 4th-century coins found, the civilian settlement continued to exist for the time being. However, there is no evidence of continued civilization between the Roman era and the Middle Ages. Foundation Based on discovery of alamannic graves, archaeologists have established the 7th century as the origination of Aalen. In the northern and western walls of St. John's church, which is located directly adjacent to the eastern gate of the Roman fort, Roman stones were incorporated. The building that exists today probably dates to the 9th century. The first mention of Aalen was in 839, when emperor Louis the Pious reportedly permitted the Fulda monastery to exchange land with the Hammerstadt village, then known as Hamarstat. Aalen itself was first mentioned in an inventory list of Ellwangen Abbey, dated ca. 1136, as the village Alon, along with a lower nobleman named Conrad of Aalen. This nobleman probably had his ancestral castle at a site south of today's town centre and was subject first to Ellwangen abbey, later to the House of Hohenstaufen, and eventually to the House of Oettingen. 1426 was the last time a member of that house was mentioned in connection with Aalen. Documents, from the Middle Ages, indicate that the town of Aalen was founded by the Hohenstaufen some time between 1241 and 1246, but at a different location than the earlier village, which was supposedly destroyed in 1388 during the war between the Alliance of Swabian Cities and the Dukes of Bavaria. Later, it is documented that the counts of Oettingen ruled the town in 1340. They are reported to have pawned the town to Count Eberhard II and subsequently to the House of Württemberg in 1358 or 1359 in exchange for an amount of money. Imperial City Designation as Imperial City During the war against Württemberg, Emperor Charles IV took the town without a fight after a siege. On 3 December 1360, he declared Aalen an Imperial City, that is, a city or town responsible only to the emperor, a status that made it a quasi-sovereign city-state and that it kept until 1803. In 1377, Aalen joined the Alliance of Swabian Cities, and in 1385, the term civitas appears in the town's seal for the first time. In 1398, Aalen was granted the right to hold markets, and in 1401 Aalen obtained proper jurisdiction. The oldest artistic representation of Aalen was made in 1528. It was made as the basis of a lawsuit between the town and the Counts of Oettingen at the Reichskammergericht in Speyer. It shows Aalen surrounded by walls, towers, and double moats. The layout of the moats, which had an embankment built between them, is recognizable by the present streets named Nördlicher, Östlicher, Südlicher and Westlicher Stadtgraben (Northern, Eastern, Southern and Western Moat respectively). The wall was about tall, 1518 single paces () long and enclosed an area of . During its early years, the town had two town gates: The Upper or Ellwangen Gate in the east, and St. Martin's gate in the south; however due to frequent floods, St. Martin's gate was bricked up in the 14th century and replaced by the Lower or Gmünd Gate built in the west before 1400. Later, several minor side gates were added. The central street market took place on the Wettegasse (today called Marktplatz, "market square") and the Reichsstädter Straße. So the market district stretched from one gate to the other, however in Aalen it was not straight, but with a 90-degree curve between southern (St. Martin's) gate and eastern (Ellwangen) gate. Around 1500, the civic graveyard was relocated from the town church to St. John's Church, and in 1514, the Vierundzwanziger ("Group of 24") was the first assembly constituted by the citizens. Reformation Delegated by Württemberg's Duke Louis III, on 28 June 1575, nearly 30 years after Martin Luther's death, Jakob Andreae, professor and chancellor of the University of Tübingen, arrived in Aalen. The sermon he gave the following day convinced the mayor, the council, and the citizens to adopt the Reformation in the town. Andreae stayed in Aalen for four weeks to help with the change. This brought along enormous changes, as the council forbade the Roman Catholic priests to celebrate masses and give sermons. However, after victories of the imperial armies at the beginning of the Thirty Years' War, the Prince-Provostry of Ellwangen, which still held the right of patronage in Aalen, were able to temporarily bring Catholicism back to Aalen; however after the military successes of the Protestant Union, Protestant church practices were instituted again. Fire of 1634 On the night of 5 September 1634, two ensigns of the army of Bernard of Saxe-Weimar who were fighting with the Swedes and retreating after the Battle of Nördlingen set fire to two powder carriages, to prevent the war material to fall into Croatian hands and to prevent their advance. The result was a conflagration, that some say destroyed portions of the town. There are differing stories regarding this fire. According to 17th-century accounts, the church and all the buildings, except of the Schwörturm tower, were casualties of the fire, and only nine families survived. 19th century research by Hermann Bauer, Lutheran pastor and local historian, discovered that the 17th-century account is exaggerated, but he does agree that the town church and buildings in a "rather large" semicircle around it were destroyed. The fire also destroyed the town archive housed in an addition to the church, with all of its documents. After the fire, soldiers of both armies went through the town looting. It took nearly 100 years for the town to reach its population of 2,000. French troops marched through Aalen in 1688 during the Nine Years' War; however, unlike other places, they left without leaving severe damages. The French came through again in 1702 during the War of the Spanish Succession and in 1741 during the War of the Austrian Succession, the latter also caused imperial troops to move through in 1743. The town church's tower collapsed in 1765, presumably because proper building techniques were not utilized during the reconstruction after the fire of 1634. The collapsing tower struck two children of the tower watchman who died of their injuries, and destroyed the nave, leaving only the altar cross intact. The remaining walls had to be knocked down due to the damage. Reconstruction began the same year, creating the building that exists today. On 22 November 1749, the so-called Aalen protocol regulating the cohabitation of Lutherans and Roman Catholics in the jointly ruled territory of Oberkochen was signed in Aalen by the Duchy of Württemberg and the Prince-Provostry of Ellwangen. Aalen had been chosen because of its neutral status as a Free Imperial City. Napoleonic era and end of the Imperial City of Aalen During the War of the First Coalition (1796), Aalen was looted. The War of the Second Coalition concluded in 1801 with the signing of the Treaty of Lunéville, which led to the German Mediatisation of 1803 that assigned most Imperial Cities to the neighbouring principalities. Aalen was assigned to the Electorate of Württemberg, which later became the Kingdom of Württemberg, and became seat of the District ("Oberamt") of Aalen. During the War of the Third Coalition, on 6 October 1805, Napoleon Bonaparte arrived in Aalen, with an army of 40,000. This event, along with Bavarian and Austrian troops moving in some days later, caused miseries that according to the town clerk "no feather could describe". In 1811, the municipality of Unterrombach was formed out of some villages previously belonging to Aalen, some to the Barons of Wöllwarth, and the eastern villages were assigned to the municipality of Unterkochen. In the age of the Napoleonic wars, the town walls were no longer of use, and in the 18th century, with the maintenance of walls, gates and towers becoming more neglected Finally, due to the fact that the funds were lacking, starting in 1800, most towers were demolished, the other buildings followed soon. Industrial revolution Before the industrial revolution, Aalen's economy was shaped by its rural setting. Many citizens were pursuing farming besides their craft, such as tanning. In the mid 19th century, there were twelve tanneries in Aalen, due to the proximity of Ulm, an important sales market. Other crafts that added to the economy were weaving mills, which produced linen and woolen goods, and baking of sweet pastry and gingerbread. In Aalen, industrialisation was a slow process. The first major increase was in the 1840s, when three factories for nails and some other factories emerged. It was the link with the railway network, by the opening of the Rems Railway from Cannstatt to Wasseralfingen in 1861, that brought more industry to Aalen, along with the royal steel mill (later Schwäbische Hüttenwerke) in Wasseralfingen. The Rems Railway's extension to Nördlingen in 1863, the opening of the Brenz Railway in 1864 and of the Upper Jagst Railway in 1866 turned Aalen into a railway hub. Furthermore, between 1901 and its shutdown in 1972, the Härtsfeld Railway connected Aalen with Dillingen an der Donau via Neresheim. Part of becoming a rail hub entailed more jobs based on the rail industry. These included, a maintenance facility, a roundhouse, an administrative office, two track maintenance shops, and a freight station with an industrial branch line. This helped shape Aalen into what today's historians call a "railwayman's town". Starting in 1866, the utilities in town all began to be upgraded. Starting with the Aalen gasworks which were opened and gas lighting was introduced. Then in 1870, a modern water supply system was started and in 1912 the mains electricity. Finally, in 1935, the first electrically powered street lights were installed. To fight housing shortage during and immediately after World War I, the town set up barracks settlement areas at the Schlauch and Alter Turnplatz grounds. In spite of the industry being crippled by the Great Depression of 1929, the public baths at the Hirschbach creek where modernized, extended and re-opened in 1931. Nazi era In the federal election of 1932, the Nazi Party performed below average in Aalen with 25.8% of votes compared to 33.1% on the national level, thus finishing second to the Centre Party which had 26.6% (11.9% nationwide) of the votes, and ahead of the Social Democratic Party of Germany with 19.8% (20.4%). However, the March 1933 federal elections showed that the sentiment had changed as the Nazi Party received 34.1% (still below German average 43.9% nationwide), but by far the leading vote-getter in Aalen, followed by the Centre party at 26.6% (11.3% nationwide) and the Social Democrats 18.6% (18.3% nationwide). The democratically elected mayor Friedrich Schwarz remained in office until the Nazis removed him from office, in 1934, and replaced him by chairman of the Nazi Party town council head and brewery owner Karl Barth. Karl Barth was a provisional mayor until the more permanent solution of Karl Schübel. In August 1934, the Nazi consumer fair Braune Messe ("brown fair") was held in Aalen. During Nazi rule in Germany, there were many military offices constructed in Aalen, starting with, in 1936, a military district riding and driving school for Wehrkreis V. The Nazis also built an army replenishment office (Heeresverpflegungsamt), a branch arsenal office (Heeresnebenzeugamt) and a branch army ammunitions institute (Heeresnebenmunitionsanstalt). Starting in 1935, mergers of neighbouring towns began. In 1938, the Oberamt was transformed into the Landkreis of Aalen and the municipality of Unterrombach was disbanded. Its territory was mostly added to Aalen, with the exception of Hammerstadt, which was added to the municipality of Dewangen. Forst, Rauental and Vogelsang were added to Essingen (in 1952 the entire former municipality of Unterrombach was merged into Aalen, with the exception of Forst, which is part of Essingen until present). In September 1944, the Wiesendorf concentration camp, a subcamp of Natzweiler-Struthof, was constructed nearby. It was designated for between 200 and 300 prisoners who were utilized for forced labor in industrial businesses nearby. Until the camp's dissolution in February 1945, 60 prisoners died. Between 1946 and 1957, the camp buildings were torn down; however, its foundations are still in place in house Moltkestraße 44/46. Also, there were several other labour camps which existed where prisoners of war along with women and men from occupied countries occupied by Germany were pooled. The prisoners at these other camps had to work for the arms industry in major businesses like Schwäbische Hüttenwerke and the Alfing Keßler machine factory. In the civic hospital, the deaconesses on duty were gradually replaced by National Socialist People's Welfare nurses. Nazi eugenics led to compulsory sterilization of some 200 persons there. Fortunately, Aalen avoided most of the combat activity during World War II. It was only during the last weeks of the war that Aalen became a target of air warfare, which led to the destruction and severe damage of parts of the town, the train station, and other railway installations. A series of air attacks lasting for more than three weeks reached its peak on 17 April 1945, when United States Army Air Forces planes bombed the branch arsenal office and the train station. During this raid, 59 people were killed, more than half of them buried by debris, and more than 500 lost their homes. Also, 33 residential buildings, 12 other buildings and 2 bridges were destroyed, and 163 buildings, including 2 churches, were damaged. Five days later, the Nazi rulers of Aalen were unseated by the US forces. Post-war era Aalen became part of the State of Baden-Württemberg, upon its creation in 1952. Then, with the Baden-Württemberg territorial reform of 1973, the District of Aalen was merged into the Ostalbkreis district. Subsequently, Aalen became seat of that district, and in 1975, the town's borough attained its present size (see below). The population of Aalen exceeded the limit of 20,000, which was the requirement for to gain the status of Große Kreisstadt ("major district town") in 1946. On 1 August 1947, Aalen was declared Unmittelbare Kreisstadt ("immediate district town"), and with the creation of the Gemeindeordnung (municipal code) of Baden-Württemberg on 1 April 1956, it was declared Große Kreisstadt. Religions On 31 December 2008, 51.1 percent of Aalen were members of the Catholic Church, 23.9 percent were members of the Evangelical-Lutheran Church. About 25 percent belong to other or no religious community or gave no information. The district of Waldhausen was the district with the highest percentage of Roman Catholic inhabitants at 75.6 percent, and the central district was the one with the highest percentage of Evangelical-Lutheran inhabitants at 25.6 percent, as well as those claiming no religious preference at 32.5 percent. Protestantism Aalen's population originally was subject to the jus patronatus of Ellwangen Abbey, and thus subject to the Roman Catholic Diocese of Augsburg. With the assistance of the Duke of Württemberg, in 1575, the reformation was implemented in Aalen. Subsequently, Aalen has been a predominantly Protestant town for centuries, with the exception of the years from 1628 until 1632 (see reformation section). Being an Imperial City, Aalen could govern its clerical matters on its own, so Clerics, organists and choir masters were direct subjects to the council, which thus exerted bishop-like power. There was even a proper hymn book for Aalen. After the transition to Württemberg, in 1803, Aalen became seat of a deanery, with the dean church being the Town Church (with the building constructed from 1765 to 1767 and existing until present). Another popular church is St. John's Church, located on the cemetery and refurbished in 1561. As Aalen's population grew in the 20th century, more parishes were founded: St. Mark's parish with its church building of 1967 and St. Martin's parish with its church of 1974. In the borough of Unterrombach, Aalen had implemented the reformation as well, but the community remained a chapel-of-ease of Aalen. A proper church, the Christ Church, was erected in 1912 and a proper parish was established in 1947. In Fachsenfeld, the ruling family of Woellwarth resp. of Leinroden implemented the reformation. A parish church was built in 1591, however with an influx of Catholics in the 18th century, a Catholic majority was established. The other districts of present-day Aalen remained mostly catholic after the reformation, however Wasseralfingen established a Lutheran parish in 1891 and a church, St. Magdalene's Church, in 1893. In Unterkochen, after World War II, a parish was established and a church was built in 1960. All four parishes belong to the deanery of Aalen within the Evangelical-Lutheran Church in Württemberg. Furthermore, in Aalen there are Old Pietistic communities. Catholicism The few Catholics of today's central district were covered by the parish of Unterkochen until the 19th century, a situation which continued for some years even after completion of St. Mary's Church in 1868, which was constructed by Georg Morlok. However, in 1872 Aalen got its proper parish again, and in 1913, a second Catholic church, Salvator's Church, was completed, and in 1969 the Holy Cross Church was also finished. In 1963, a second parish was set up, and in 1972 it got a new Church, the new St. Mary's Church, which has been erected in place of the old St. Mary's church, which had been torn down in 1968. Another church of the second parish was St. Augustine's Church, which was completed in 1970. Finally, in 1976 and 1988, St. Elizabeth's Church and St. Thomas' Church were completed. Furthermore, in 1963, the St. Michael pastoral care office was built. Hofherrnweiler has its own Catholic church, St. Boniface's, since 1904. The villages of Dewangen, Ebnat, Hofen, Waldhausen and Wasseralfingen had remained Catholic after reformation, so old parishes and churches persist there. The Assumption of Mary Church in Dewangen has an early Gothic tower and a newly built nave (1875). Mary's Immaculate Conception Church in Ebnat was constructed in 1723; however the church was first mentioned in 1298. Hofen's Saint George's Church is a fortified church, whose current nave was built between 1762 and 1775. Alongside the church, the Late Gothic St. Odile's Chapel is standing, whose entrance has the year 1462 engraved upon it. Foundations of prior buildings have been dated to the 11th and 13th century. St. Mary's Church of Unterkochen was first mentioned in 1248, and has served the Catholics of Aalen for a long time. Waldhausen's parish church of St. Nicholas was built between 1699 and 1716. Wasseralfingen at first was a chapel of ease for Hofen, but has since had its own chapel, St. Stephen, built. It was presumably built in 1353 and remodeled in 1832. In 1834, a proper parish was established, which built a new St. Stephen's Church. This new building utilized the Romanesque Revival architecture style and was built between 1881 and 1883, and has since remained the parish's landmark. Also, Fachsenfeld received its own church, named Sacred Heart in 1895. All Catholic parishes within Aalen are today incorporated into four pastoral care units within the Ostalb Deanery of the Diocese of Rottenburg-Stuttgart; however these units also comprise some parishes outside of Aalen. Pastoral Care Unit two comprises the parishes of Essingen, Dewangen and Fachsenfeld, unit four comprises Hofen and Wasseralfingen, unit five comprises both parishes of Aalen's centre and Hofherrnweiler, unit five comprises Waldhausen, Ebnat, Oberkochen and Unterkochen. Other Christian communities In addition to the two major religions within Aalen, there are also free churches and other communities, including the United Methodist Church, the Baptists, the Seventh-day Adventist Church and the New Apostolic Church. Other religions Until the late 19th century, no Jews were documented within Aalen. In 1886 there were four Jews were living in Aalen, a number that rose to ten in 1900, fell to seven in 1905, and remained so until 1925. Upon the Nazis' rise to power in 1933, seven Jews, including two children, lived in Aalen. During the Kristallnacht in 1938, the vitrines of the three Jewish shops in the town were smashed and their proprietors imprisoned for several weeks. After their release, most Aalen Jews emigrated. The last Jews of Aalen, Fanny Kahn, was forcibly resettled to Oberdorf am Ipf, which had a large Jewish community. Today, a street of Aalen is named after her. The Jew Max Pfeffer returned from Brussels to Aalen in 1948 to continue his shop, but emigrated to Italy in 1967. In Aalen, there is an Islamic Ditib community, which maintains the D.I.T.I.B. Mosque of Aalen (Central Mosque) located at Ulmer Straße. The mosque's construction started on 30 August 2008. The Islamist Millî Görüş organisation maintains the Fatih Mosque, as well at Ulmer Straße. Mergings The present-day make up of Aalen was created on 21 June 1975 by the unification of the cities of Aalen and Wasseralfingen, with the initial name of Aalen-Wasseralfingen. This annexation made Aalen's territory one third larger than its prior size. On 1 July 1975, the name Aalen was revived. Prior to this merger, the town of Aalen had already annexed the following municipalities: 1938: Unterrombach 1 January 1970: Waldhausen 1 July 1972: Ebnat 1 January 1973: Dewangen, Fachsenfeld (including the village of Hangendenbach, which was transferred from Abtsgmünd in 1954) and Unterkochen. The merging of Dewangen nearly doubled the territory of Aalen. Population's progression and structure During the Middle Ages and the early modern period, Aalen was just a small town with a few hundred inhabitants. The population grew slowly due to numerous wars, famines and epidemics. It was the beginning of the Industrial Revolution in the 19th century where Aalen's growth accelerated. Whereas in 1803, only 1,932 people inhabited the town, in 1905 it had already increased to 10,442. The number continued to rise and reached 15,890 in 1939. The influx of refugees and ethnic Germans from Germany's former eastern territories after World War II pushed the population to 31,814 in 1961. The merger with Wasseralfingen on 21 June 1975 added 14,597 persons and resulted in a total population of 65,165 people. On 30 June 2005, the population, which was officially determined by the Statistical Office of Baden-Württemberg, was 67,125. The following overview shows how the population figures of the borough were ascertained. Until 1823, the figures are mostly estimates, thereafter census results or official updates by the state statistical office. Starting in 1871, the figures were determined by non-uniform method of tabulation using extrapolation. ¹ Census result On 31 December 2008, Aalen had precisely 66,058 inhabitants, of which 33,579 were female and 32,479 were male. The average age of Aalen's inhabitants rose from 40.5 years in 2000 to 42.4 in 2008. Within the borough, 6,312 foreigners resided, which is 9.56 percent. Of them, the largest percentage are from Turkey (38 percent of all foreigners), the second largest group are from Italy (13 percent), followed by Croatians (6 percent) and Serbs (5 percent). The number of married residents fell from 32,948 in 1996 to 31,357 in 2007, while the number of divorced residents rose in the same period from 2,625 to 3,859. The number of single residents slightly increased between 1996 and 2004 from 25,902 to 26,268 and fell slightly until 2007 to 26,147. The number of widowed residents fell from 5,036 in 1996 to 4,783 in 2007. Politics Aalen has arranged a municipal association with Essingen and Hüttlingen. Council Since the local election of 25 May 2014, the town council consists of 51 representatives having a term of five years. The seats are distributed as follows on parties and groups (changes refer to the second last election of 2004): Mayors Since 1374, the mayor and the council maintain the government of the town. In the 16th century, the town had two, sometimes three mayors, and in 1552, the council had 13 members. Later, the head of the administration was reorganized several times. In the Württemberg era, the mayor's title was initially called Bürgermeister, then from 1819 it was Schultheiß, and since 1947 it is Oberbürgermeister. The mayor is elected for a term of eight years, and he is chairman and a voting member of the council. He has one deputy with the official title of Erster Bürgermeister ("first mayor") and one with the official title of Bürgermeister ("mayor"). Heads of town in Aalen since 1802 1802–: Theodor Betzler 1812–1819: Ludwig Hölder 1819–1829: Theodor Betzler 1829: Palm 1829–1848: Philipp Ehmann 1848–1873: Gustav Oesterlein 1873–1900: Julius Bausch 1900–1902: Paul Maier 1903–1934: Friedrich Schwarz 1935–1945: Karl Schübel (NSDAP) 1945–1950: Otto Balluff 1950–1975: Karl Schübel (independent) 1976–2005: Ulrich Pfeifle (SPD) 2005–2013: Martin Gerlach (independent) 2013–2021: Thilo Rentschler (SPD) 2021–: Frederick Brütting (SPD) Coat of arms and flag Aalen's coat of arms depicts a black eagle with a red tongue on golden background, having a red shield on its breast with a bent silver eel on it. Eagle and eel were first acknowledged as Aalen's heraldic animals in the seal of 1385, with the eagle representing the town's imperial immediacy. After the territorial reform, it was bestowed again by the Administrative District of Stuttgart on 16 November 1976. The coat of arms' blazon reads: "In gold, the black imperial eagle, with a red breast shield applied to it, therein a bent silver eel" (In Gold der schwarze Reichsadler, belegt mit einem roten Brustschild, darin ein gekrümmter silberner Aal). Aalen's flag is striped in red and white and contains the coat of arms. The origin of the town's name is uncertain. Matthäus Merian (1593–1650) presumed the name to originate from its location at the Kocher river, where "frequently eels are caught", while Aal is German for "eel". Other explanations point to Aalen as the garrison of an ala during the Roman empire, respectively to an abridgement of the Roman name "Aquileia" as a potential name of the Roman fort, a name that nearby Heidenheim an der Brenz bore as well. Another interpretation points to a Celtic word aa meaning "water". Godparenthood On the occasion of the 1980 Reichsstädter Tage, Aalen took over godparenthood for the more than 3000 ethnic Germans displaced from the Wischau linguistic enclave. 972 of them settled in Aalen in 1946. The "Wischau Linguistic Enclave Society" (Gemeinschaft Wischauer Sprachinsel) regularly organises commemorative meetings in Aalen. Their traditional costumes are stored in the Old Town Hall. Municipal finances According to the 2007 municipal poll by the Baden-Württemberg chapter of the German Taxpayers Federation, municipal tax revenues totalling to 54,755 million Euros (2006) resp. 62,148 million Euros (2007) face the following debts: 2006 total: 109.9 million Euros debts (64.639 million of the finance department and 48.508 million of the municipal enterprises and fund assets) 2007 total: 114.5 million Euros debts (69.448 million of the finance department and 45.052 million of the municipal enterprises and fund assets) Twin towns – sister cities Aalen is twinned with: Saint-Lô, France (1978) Christchurch, United Kingdom (1981) Tatabánya, Hungary (1987) Antakya, Turkey (1995); initiated by Ismail Demirtas, who emigrated in 1962 from Turkey to Aalen and was social adviser for foreign employees Cervia, Italy (2011) Vilankulo, Mozambique (2018) The "Twin Towns Society of Aalen" (Städtepartnerschaftsverein Aalen e. V.) promotes friendly relations between Aalen and its twin towns, which comprises mutual exchanges of sports and cultural clubs, schools and other civic institutions.

Culture and sights Theatre The Theater der Stadt Aalen theatre was founded in 1991 and stages 400 to 500 performances a year. Schubart Literary Award The town endowed the "Schubart Literary Award" (Schubart-Literaturpreis) in 1955 in tribute to Christian Friedrich Daniel Schubart, who spent his childhood and youth in Aalen. It is one of the earliest literary awards in Baden-Württemberg and is awarded biennially to German-language writers whose work coincide with Schubart's "liberal and enlightened reasoning". It is compensated with 12,000 Euros. Music Founded in 1958, the "Music School of the Town of Aalen" today has about 1,500 students taught by 27 music instructors in 30 subjects. In 1977, a symphony orchestra was founded in Aalen, which today is called Aalener Sinfonieorchester, and consists mostly of instructors and students of the music school. It performs three public concerts annually: The "New Year's Concert" in January, the "Symphony Concert" in July and a "Christmas Concert" in December. Beyond that, music festivals regularly take place in Aalen, like the Aalen Jazzfest. The Aalen volunteer fire department has had a marching band since 1952, whose roots date back to 1883. In 1959, the band received its first glockenspiel from TV host Peter Frankenfeld on the occasion of a TV appearance. A famous German rapper, designer and singer, that goes under the name of Cro, was born in Aalen and lived his early years here. Arts The Kunstverein Aalen was founded in 1983 as a non-profit art association and today is located in the Old Town Hall. The institution with more than 400 members focuses on solo and group exhibitions by international artists. It belongs to the Arbeitsgemeinschaft Deutscher Kunstvereine (ADKV), an umbrella organization for non-profit art associations. Museums and memorial sites Museums In the central district of Aalen, there are two museums: The "Aalen Limes Museum" (Limesmuseum Aalen) is located at the place of the largest Roman cavalry fort north of the Alps until about 200 AD. It opened in 1964. The museum exhibits numerous objects from the Roman era. The ruins of the cavalry fort located beside the museum is open to museum visitors. Every other year, a Roman festival is held in the area of the museum (see below). In the Geological-Paleontological Museum located in the historic town hall, there are more than 1500 fossils from the Swabian Jura, including ammonites, ichthyosaurs and corals, displayed. In the Waldhausen district the Heimatstüble museum of local history has an exhibition on agriculture and rural living. In the Wasseralfingen district, there are two more museums: The Museum Wasseralfingen comprises a local history exhibition and an art gallery including works of Hermann Plock, Helmut Schuster and Sieger Köder. Also, the stove plate collection of the Schwäbische Hüttenwerke steel mill is exhibited, with artists, modellers and the production sequence of a cast plate from design to final product being presented. Memorial sites There is memorial stone at the Schillerlinde tree above Wasseralfingen's ore pit dedicated to four prisoners of the subcamp of Natzweiler-Struthof concentration camp killed there. Also in Wasseralfingen, in the cemetery a memorial with the Polish inscription "To the victims of Hitler" which commemorates the deceased forced labourers buried there. In 1954, on the Schillerhöhe hill the town erected a bell tower as a memorial to Aalen's victims of both world wars and to the displacement of ethnic Germans. The tower was planned by Emil Leo, the bell was endowed by Carl Schneider. The tower is open on request. Every evening at 18:45 (before 2003: at 19:45), the memorial's bell rings. Buildings Churches The town centre is dominated by the Evangelical-Lutheran St. Nicholas' Church in the heart of the pedestrian area. The church, in its present shape being built between 1765 and 1767, is the only major Late Baroque building in Aalen and is the main church of the Evangelical-Lutheran parish of Aalen. St. John's Church is located inside of St. John's cemetery in the western centre. The building presumably is from the 9th century and thus is one of Württemberg's oldest existing churches. The interior features frescos from the early 13th century. For other churches in Aalen, see the Religions section. Historic Town Hall with "Spy" The Historic Town Hall was originally built in the 14th century. After the fire of 1634, it was re-constructed in 1636. This building received a clock from Lauterburg, and the Imperial City of Nuremberg donated a Carillon. It features a figurine of the "Spy of Aalen" and historically displayed other figurines, however the latter ones were lost by a fire in 1884. Since then, the Spy resides inside the reconstructed tower and has become a symbol of the town. The building was used as the town hall until 1907. Since 1977, the Geological-Paleontological Museum resides in the Historic Town Hall. According to legend, the citizens of Aalen owe the "Spy of Aalen" (Spion von Aalen) their town having been spared from destruction by the emperor's army: The Imperial City of Aalen was once in quarrel with the emperor, and his army was shortly before the gates to take the town. The people of Aalen got scared and thus dispatched their "most cunning" one out into the enemy's camp to spy out the strength of their troops. Without any digression, he went straight into the middle of the enemy camp, which inescapably led to him being seized and presented to the emperor. When the emperor asked him what he had lost here, he answered in Swabian German: "Don't frighten, high lords, I just want to peek how many cannons and other war things you've got, since I am the spy of Aalen". The emperor laughed upon such a blatancy and acted naïvety, steered him all through the camp and then sent him back home. Soon the emperor withdrew with his army as he thought a town such wise guys reside in deserved being spared. Old Town Hall The earliest record of the Old Town Hall was in 1575. Its outside wall features the oldest known coat of arms, which is of 1664. Until 1851, the building also housed the Krone-Post hotel, which coincided with being a station of the Thurn und Taxis postal company. It has housed many notable persons. Thus the so-called "Napoleon Window" with its "N" painted on reminds of the stay of French emperor Napoleon Bonaparte in 1805. According to legend, he rammed his head so hard it bled on this window, when he was startled by the noise of his soldiers ridiculing the "Spy of Aalen". The building was used as Aalen's town hall from 1907 until 1975. Today it houses a cabaret café and the stage of the Theatre of the Town of Aalen. The town has adopted the Wischau Linguistic Enclave Society due to their godparenthood and stores their traditional costumes in the building. Bürgerspital The Bürgerspital ("Civic Asylum") is a timber-frame house erected on Spritzenhausplatz ("Fire Engine House Square") in 1702. Until 1873, it was used as civic hospital, then, later as a retirement home. After a comprehensive renovation in 1980 it was turned into a senior citizen's community centre. Limes-Thermen On a slope of the Langert mountain, south of the town, the Limes-Thermen ("Limes Thermae") hot springs are located. They were built in ancient Roman style and opened in 1985. The health spa is supplied with water about . Market square The market square is the historic hub of Aalen and runs along about from the town hall in the south to the Historic Town Hall and the Old Town Hall in the north, where it empties into Radgasse alley. Since 1809, it is site of the weekly market on Wednesday and Saturday. About in front of the Reichsstädter Brunnen fountain at the town hall, the coats of arms of Aalen, its twinned cities and of the Wischau linguistic enclave are paved into the street as mosaic. Market fountain In 1705, for the water supply of Aalen a well casing was erected at the northern point of the market square, in front of the Historic Town Hall. It was a present of duke Eberhard Louis. The fountain bore a statue of emperor Joseph I., who was enthroned in 1705 and in 1707 renewed Aalen's Imperial City privileges. The fountain was supplied via a wooden pipe. Excessive water was dissipated through ditches branched from Kocher river. When in the early 1870s Aalen's water network was constructed, the fountain was replaced by a smaller fountain about distant. In 1975, the old market fountain was re-erected in baroque style. It bears a replica of the emperor's statue, with the original statue exhibited in the new town hall's lobby. The cast iron casing plates depict the 1718 coat of arms of the Duchy of Württemberg and the coats of arms of Aalen and of the merged municipalities. Reichsstädter Brunnen The Reichsstädter Brunnen fountain ("Imperial Civic Fountain") is located in front of the town hall at the southern point of the market square. It was created by sculptor Fritz Nuss in 1977 to commemorate Aalen's time as an Imperial City (1360–1803). On its circumference is a frieze showing bronze figurines illustrating the town's history. Radgasse The Radgasse ("Wheel Alley") features Aalen's oldest façade. Originally a small pond was on its side. The buildings were erected between 1659 and 1662 for peasants with citizenry privileges and renovated in the mid-1980s. The namesake for the alley was the "Wheel" tavern, which was to be found at the site of today's address Radgasse 15. Tiefer Stollen The former iron ore pit Wilhelm at Braunenberg hill was converted into the Tiefer Stollen tourist mine in order to remind of the old-day miners' efforts and to maintain it as a memorial of early industrialisation in the Aalen area. It has a mining museum open for visitors, and a mine railway takes visitors deep into the mountain. The Town of Aalen, a sponsorship association, and many citizens volunteered several thousand hours of labour to put the mine into its current state. As far as possible, things were left in the original state. In 1989, a sanitary gallery was established where respiratory diseases are treated within rest cures. Thus the Aalen village of Röthard, where the gallery is located, was awarded the title of "Place with sanitary gallery service" in 2004. Observatory The Aalen Observatory was built in 1969 as school observatory for the Schubart Gymnasium. In 2001, it was converted to a public observatory. Since then, it has been managed by the Astronomische Arbeitsgemeinschaft Aalen ("Aalen Astronomical Society"). It is located on Schillerhöhe hill and features two refractive telescopes. They were manufactured by Carl Zeiss AG which has its headquarters in nearby Oberkochen and operates a manufacturing works in Aalen (see below). In the observatory, guided tours and lectures are held regularly. Windpark Waldhausen The Windpark Waldhausen wind farm began operations in early 2007. It consists of seven REpower MM92 wind turbines with a nameplate capacity of 2 MW each. The hub height of each wind turbine is , with a rotor diameter of . Aalbäumle observation tower The tall Aalbäumle observation tower is built atop Langert mountain. This popular hiking destination was built in 1898 and was remodelled in 1992. It features a good view over Aalen and the Welland region, up to the Rosenstein mountain and Ellwangen. Beneath the tower, an adventure playground and a cabin is located. A flag on the tower signals whether the cabin's restaurant is open. Natural monuments The Baden-Württemberg State Institute for Environment, Measurements and Natural Conservation has laid out six protected landscapes in Aalen (the Swabian Jura escarpment between Lautern and Aalen with adjacent territories, the Swabian Jura escarpment between Unterkochen and Baiershofen, the Hilllands around Hofen, the Kugeltal and Ebnater Tal valleys with parts of Heiligental valley and adjacent territories, Laubachtal valley and Lower Lein Valley with side valleys), two sanctuary forests (Glashütte and Kocher Origin), 65 extensive natural monuments, 30 individual natural monuments and the following two protected areas: The large Dellenhäule protected area between Aalen's Waldhausen district and Neresheim's Elchingen district, created in 1969, is a sheep pasture with juniper and wood pasture of old willow oaks.

The commercial broadcasters Radio Ton and Radio 7 have studios in Aalen. Education A Latin school was first recorded in Aalen in 1447; it was remodeled in 1616 and also later in various buildings that were all situated near the town church, and continued up through the 19th century. In the course of the reformation, a "German school" was established in tandem, being a predecessor of the latter Volksschule school type. In 1860, the Ritterschule was built as a Volksschule for girls; the building today houses the Pestalozzischule. In 1866, a new building was erected for the Latin school and for the Realschule established in 1840. This building, later known as the Alte Gewerbeschule, was torn down in 1975 to free up land for the new town hall. In 1912, the Parkschule building was opened. It was designed by Paul Bonatz and today houses the Schubart-Gymnasium. The biggest educational institution in the town is the Hochschule Aalen, which was founded in 1962 and focuses on engineering and economics. It is attended by 5000 students on five campuses and employs 129 professors and 130 other lecturers. The town provides three Gymnasiums, four Realschulen, two Förderschulen (special schools), six combined Grundschulen and Hauptschulen and eight standalone Grundschulen. The Ostalbkreis district provides three vocational schools and three additional special schools. Finally, six non-state schools of various types exist. The German Esperanto Library (German: Deutsche Esperanto-Bibliothek, Esperanto: Germana Esperanto-Biblioteko) has been located in the building of the town library since 1989. TV and radio transmission tower The Südwestrundfunk broadcasting company operates the Aalen transmission tower on the Braunenberg hill. The tower was erected in 1956, it is tall and made of reinforced concrete.

American Airlines is a major US-based airline headquartered in Fort Worth, Texas, within the Dallas–Fort Worth metroplex. It is the largest airline in the world when measured by scheduled passengers carried and revenue passenger mile. American, together with its regional partners and affiliates, operates an extensive international and domestic network with almost 6,800 flights per day to nearly 350 destinations in 48 countries. American Airlines is a founding member of the Oneworld alliance. Regional service is operated by independent and subsidiary carriers under the brand name American Eagle. American Airlines and American Eagle operate out of 10 hubs, with Dallas/Fort Worth International Airport (DFW) being its largest. The airline handles more than 200 million passengers annually with an average of more than 500,000 passengers daily. As of 2022, the company employs 129,700 staff members. History American Airlines was started in 1930 via a union of more than eighty small airlines. The two organizations from which American Airlines was originated were Robertson Aircraft Corporation and Colonial Air Transport. The former was first created in Missouri in 1921, with both being merged in 1929 into holding company The Aviation Corporation. This, in turn, was made in 1930 into an operating company and rebranded as American Airways. In 1934, when new laws and attrition of mail contracts forced many airlines to reorganize, the corporation redid its routes into a connected system and was renamed American Airlines. The airline fully developed its international business between 1970 and 2000. It purchased Trans World Airlines in 2001. American had a direct role in the development of the Douglas DC-3, which resulted from a marathon telephone call from American Airlines CEO C. R. Smith to Douglas Aircraft Company founder Donald Wills Douglas Sr., when Smith persuaded a reluctant Douglas to design a sleeper aircraft based on the DC-2 to replace American's Curtiss Condor II biplanes. (The existing DC-2's cabin was wide, too narrow for side-by-side berths.) Douglas agreed to go ahead with development only after Smith informed him of American's intention to purchase 20 aircraft. The prototype DST (Douglas Sleeper Transport) first flew on December 17, 1935, the 32nd anniversary of the Wright Brothers' flight at Kitty Hawk. Its cabin was wide, and a version with 21 seats instead of the 14–16 sleeping berths of the DST was given the designation DC-3. There was no prototype DC-3; the first DC-3 built followed seven DSTs off the production line and was delivered to American Airlines. American Airlines inaugurated passenger service on June 26, 1936, with simultaneous flights from Newark, New Jersey, and Chicago, Illinois. American also had a direct role in the development of the DC-10, which resulted from a specification from American Airlines to manufacturers in 1966 to offer a widebody aircraft that was smaller than the Boeing 747, but capable of flying similar long-range routes from airports with shorter runways. McDonnell Douglas responded with the DC-10 trijet shortly after the two companies' merger. On February 19, 1968, the president of American Airlines, George A. Spater, and James S. McDonnell of McDonnell Douglas announced American's intention to acquire the DC-10. American Airlines ordered 25 DC-10s in its first order. The DC-10 made its first flight on August 29, 1970, and received its type certificate from the FAA on July 29, 1971. On August 5, 1971, the DC-10 entered commercial service with American Airlines on a round trip flight between Los Angeles and Chicago. In 2011, due to a downturn in the airline industry, American Airlines' parent company, the AMR Corporation, filed for bankruptcy protection. In 2013, American Airlines merged with US Airways but kept the American Airlines name, as it was the better-recognized brand internationally; the combination of the two airlines resulted in the creation of the largest airline in the United States, and ultimately the world. Destinations and hubs Destinations As of July 2022, American Airlines flies to 269 domestic destinations and 81 international destinations in 58 countries (as of August 2022) in five continents. Hubs American currently operates ten hubs. Charlotte – American's hub for the southeastern United States and secondary Caribbean gateway. Its operations in Concourse E are the largest regional flight operation in the world. American has about 91% of the market share at CLT, making it the largest carrier at the airport. It is a former US Airways hub. Chicago–O'Hare – American's hub for the Midwest. American has about 35% of the market share at O'Hare, making it the airport's second largest airline after United. Dallas/Fort Worth – American's hub for the southern United States and largest hub overall. American currently has about 87% of the market share at DFW, making it the largest carrier at the airport. American's corporate headquarters are also in Fort Worth near the airport. DFW serves as American's primary Transpacific hub, primary gateway to Mexico and its secondary gateway to Latin America. Los Angeles – American's hub for the West Coast and secondary transpacific gateway. Though American has increasingly reduced its network out of Los Angeles, citing many long-haul international routes as unprofitable, it still maintains a handful of transatlantic and transpacific flights. Miami – American's primary Latin American and Caribbean hub. American has about 68% of the market share in Miami, making it the largest airline at the airport. New York–JFK – American's primary transatlantic hub, while including other select flights to South America and Asia. Mostly serves destinations with a lot of business traffic. American has about 12% of the market share at JFK, making it the third largest carrier at the airport behind Delta and JetBlue. New York–LaGuardia – American's second New York hub. Philadelphia – American's primary Northeast domestic hub and secondary transatlantic hub, primarily for London, Paris, and leisure destinations in Western and Southern Europe. American has about 70% of the market share at PHL, making it the airport's largest airline. Another former US Airways hub. Phoenix–Sky Harbor – American's Rocky Mountain hub. Currently American has about 33% of the market share at PHX, making it the airport's second-largest airline. Former US Airways hub. Washington–Reagan – American's hub for the capital of the United States. American has about 49% of the market share at DCA, making it the largest carrier at the airport. Former US Airways hub. Alliance and codeshare agreements American Airlines is a member of the Oneworld alliance and has codeshares with the following airlines: Aer Lingus Air Tahiti Nui Alaska Airlines Cape Air Cathay Pacific China Southern Airlines El Al Fiji Airways Gol Transportes Aéreos Hawaiian Airlines IndiGo JetSmart Jetstar Jetstar Japan Level Korean Air Malaysia Airlines Qatar Airways Royal Air Maroc Royal Jordanian Seaborne Airlines Silver Airways SriLankan Airlines Vueling Joint ventures In addition to the above codeshares, American Airlines has entered into joint ventures with the following airlines: British Airways Finnair Iberia Japan Airlines Qantas Fleet As of January 2023, American Airlines operates the largest commercial fleet in the world, comprising 933 aircraft from both Boeing and Airbus, with an additional 161 planned or on order. Over 80% of American's aircraft are narrow-bodies, mainly Airbus A320 series and the Boeing 737-800. It is the largest A320 series aircraft operator in the world, as well as the largest operator of the A319 and A321 variants. It is the fourth-largest operator of 737 family aircraft and second-largest operator of the 737-800 variant. American's wide-body aircraft are all Boeing airliners. It is the third-largest operator of the Boeing 787 series and the sixth-largest operator of the Boeing 777 series. American exclusively ordered Boeing aircraft throughout the 2000s. This strategy shifted on July 20, 2011, when American announced the largest combined aircraft order in history for 460 narrow-body jets including 260 aircraft from the Airbus A320 series. Additional Airbus aircraft joined the fleet in 2013 during the US Airways merger, which operated a nearly all Airbus fleet. On August 16, 2022, American announced that a deal had been confirmed with Boom Supersonic to purchase at least 20 of their Overture supersonic airliners and potentially up to 60 in total. American Airlines operates aircraft maintenance and repair bases at the Charlotte, Chicago O'Hare, Dallas–Fort Worth, Pittsburgh, and Tulsa airports. Only American's widebody planes and its specially-configured Airbus A321T feature seatback entertainment. All other A321 and all Boeing 737 planes were retrofitted with their "Oasis" configuration. While this configuration adds larger overhead bins, it also added more seats, reduced legroom and seat padding, and removed seatback entertainment, which has drawn ire from some travelers. Cabins Flagship First Flagship First is American's international and transcontinental first class product. It is offered only on Boeing 777-300ERs and select Airbus A321s which American designates "A321T". The seats are fully lie-flat and offer direct aisle access with only one on each side of the aisle in each row. As with the airline's other premium cabins, Flagship First offers wider food and beverage options, larger seats, and lounge access at certain airports. American offers domestic Flagship First service on transcontinental routes between New York–JFK and Los Angeles, New York–JFK and San Francisco, New York-JFK and Santa Ana, Boston and Los Angeles, and Miami and Los Angeles, as well as on the standard domestic route between New York-JFK and Boston. The airline will debut new Flagship Suite® premium seats and a revamped aircraft interior for its long-haul fleet with fresh deliveries of its Airbus A321XLR and Boeing 787-9 aircraft, beginning in 2024. Flagship Business Flagship Business is American's international and transcontinental business class product. It is offered on all Boeing 777-200ERs, Boeing 777-300ERs, Boeing 787-8s, and Boeing 787-9s, as well as select Airbus A321s. All Flagship Business seats are fully lie-flat. The amenities in Flagship Business include complimentary alcoholic/non-alcoholic beverages, multi-course meals, and lounge access. Domestic first class First class is offered on all domestically configured aircraft. Seats range from in width and have of pitch. Dining options include complementary alcoholic and non-alcoholic beverages on all flights as well as standard economy snack offerings, enhanced snack basket selections on flights over , and meals on flights or longer. Premium Economy is American's economy plus product. It is offered on all widebody aircraft. The cabin debuted on the airline's Boeing 787-9s in late 2016 and is also available on Boeing 777-200s and -300s, and Boeing 787-8s. Premium Economy seats are wider than seats in the main cabin (American's economy cabin) and provide more amenities: Premium Economy customers get two free checked bags, priority boarding, and enhanced food and drink service including free alcohol. This product made American Airlines the first U.S. carrier to offer a four-cabin aircraft. Main Cabin Extra is American's enhanced economy product. It is available on all of the mainline fleet and American Eagle aircraft. Main Cabin Extra seats include greater pitch than is available in main cabin, along with free alcoholic beverages and boarding one group ahead of main cabin. American retained Main Cabin Extra when the new Premium Economy product entered service in late 2016. Main Cabin Main Cabin (economy class) is American's economy product and is found on all mainline and regional aircraft in its fleet. Seats range from in width and have of pitch. American markets a number of rows within the main cabin immediately behind Main Cabin Extra as "Main Cabin Preferred", which require an extra charge to select for those without status. American Airlines marketed increased legroom in economy class as "More Room Throughout Coach", also referred to as "MRTC", starting in February 2000. Two rows of economy class seats were removed on domestic narrowbody aircraft, resulting in more than half of all standard economy seats having a pitch of or more. Amid financial losses, this scheme was discontinued in 2004. On many routes, American also offers Basic Economy, the airline's lowest main cabin fare. Basic Economy consists of a Main Cabin ticket with numerous restrictions including waiting until check-in for a seat assignment, no upgrades or refunds, and boarding in the last group. Originally Basic Economy passengers could only carry a personal item, but American later revised their Basic Economy policies to allow for a carry-on bag. In May 2017, American announced it would be adding more seats to some of its Boeing 737 MAX 8 jets and reducing overall legroom in the basic economy class. The last three rows were to lose , going from the current . The remainder of the main cabin was to have of legroom. This "Project Oasis" seating configuration has since been expanded to all 737 MAX 8s as well as standard Boeing 737-800 and non-transcontinental Airbus A321 jets. New Airbus A321neo jets have been delivered with the same configuration. This configuration has been considered unpopular with passengers, especially American's frequent flyers, as the new seats have less padding, less legroom, and no seatback entertainment. Reward programs AAdvantage AAdvantage is the frequent flyer program for American Airlines. It was launched on May 1, 1981, and it remains the largest frequent flyer program with over 115 million members as of 2021. Miles accumulated in the program allow members to redeem tickets, upgrade service class, or obtain free or discounted car rentals, hotel stays, merchandise, or other products and services through partners. The most active members, based on the accumulation of Loyalty Points with American Airlines, are designated AAdvantage Gold, AAdvantage Platinum, AAdvantage Platinum Pro, and AAdvantage Executive Platinum elite members, with privileges such as separate check-in, priority upgrade, and standby processing, or free upgrades. AAdvantage status correspond with Oneworld status levels allowing elites to receive reciprocal benefits from American's oneworld partner airlines. AAdvantage co-branded credit cards are also available and offer other benefits. The cards are issued by CitiCards, a subsidiary of Citigroup, Barclaycard, and Bilt card in the United States, by several banks including Butterfield Bank and Scotiabank in the Caribbean, and by Banco Santander in Brazil. AAdvantage allows one-way redemption, starting at 7,500 miles. Admirals Club The Admirals Club was conceived by AA president C.R. Smith as a marketing promotion shortly after he was made an honorary Texas Ranger. Inspired by the Kentucky colonels and other honorary title designations, Smith decided to make particularly valued passengers "admirals" of the "Flagship fleet" (AA called its aircraft "Flagships" at the time). The list of admirals included many celebrities, politicians, and other VIPs, as well as more "ordinary" customers who had been particularly loyal to the airline. There was no physical Admirals Club until shortly after the opening of LaGuardia Airport. During the airport's construction, New York Mayor Fiorello LaGuardia had an upper-level lounge set aside for press conferences and business meetings. At one such press conference, he noted that the entire terminal was being offered for lease to airline tenants; after a reporter asked whether the lounge would be leased as well, LaGuardia replied that it would, and a vice president of AA immediately offered to lease the premises. The airline then procured a liquor license and began operating the lounge as the "Admirals Club" in 1939. The second Admirals Club opened at Washington National Airport. Because it was illegal to sell alcohol in Virginia at the time, the club contained refrigerators for the use of its members, so they could store their liquor at the airport. For many years, membership in the Admirals Club (and most other airline lounges) was by the airline's invitation. After a passenger sued for discrimination, the club switched to a paid membership program in 1974. Flagship Lounge Though affiliated with the Admirals Club and staffed by many of the same employees, the Flagship Lounge is a separate lounge specifically designed for customers flying in first class and business class on international flights and transcontinental domestic flights. Corporate affairs Business trends The key trends for American Airlines are (as of the financial year ending 31 December): Ownership and structure American Airlines, Inc., is publicly traded through its parent company, American Airlines Group Inc., under NASDAQ: AAL , with a market capitalization of about $12 billion as of 2019, and is included in the S&P 500 index. American Eagle is a network of six regional carriers that operate under a codeshare and service agreement with American, operating flights to destinations in the United States, Canada, the Caribbean, and Mexico. Three of these carriers are independent and three are subsidiaries of American Airlines Group: Envoy Air Inc., Piedmont Airlines, Inc., and PSA Airlines Inc. Headquarters American Airlines is headquartered across several buildings in Fort Worth, Texas that it calls the "Robert L. Crandall Campus" in honor of former president and CEO Robert Crandall. The square-foot, five-building office complex called was designed by Pelli Clarke Pelli Architects. The campus is located on 300 acres, adjacent to Dallas/Fort Worth International Airport, American's fortress hub. Before it was headquartered in Texas, American Airlines was headquartered at 633 Third Avenue in the Murray Hill area of Midtown Manhattan, New York City. In 1979, American moved its headquarters to a site at Dallas/Fort Worth International Airport, which affected up to 1,300 jobs. Mayor of New York City Ed Koch described the move as a "betrayal" of New York City. American moved to two leased office buildings in Grand Prairie, Texas. On January 17, 1983, the airline finished moving into a $150 million ($ when adjusted for inflation), facility in Fort Worth; $147 million (about $ when adjusted for inflation) in Dallas/Fort Worth International Airport bonds financed the headquarters. The airline began leasing the facility from the airport, which owns the facility. Following the merger of US Airways and American Airlines, the new company consolidated its corporate headquarters in Fort Worth, abandoning the US Airways headquarters in Phoenix, AZ. As of 2015, American Airlines is the corporation with the largest presence in Fort Worth. In 2015, American announced that it would build a new headquarters in Fort Worth. Groundbreaking began in the spring of 2016 and occupancy completed in September 2019. The airline plans to house 5,000 new workers in the building. It will be located on a property adjacent to the airline's flight academy and conference and training center, west of Texas State Highway 360, west from the current headquarters. The airline will lease a total of from Dallas–Fort Worth International Airport and this area will include the headquarters. Construction of the new headquarters began after the demolition of the Sabre facility, previously on the site. The airline considered developing a new headquarters in Irving, Texas, on the old Texas Stadium site, before deciding to keep the headquarters in Fort Worth. Corporate identity Logo In 1931, Goodrich Murphy, an American employee, designed the AA logo as an entry in a logo contest. The eagle in the logo was copied from a Scottish hotel brochure. The logo was redesigned by Massimo Vignelli in 1967. Thirty years later, in 1997, American Airlines was able to make its logo Internet-compatible by buying the domain AA.com. AA is also American's two-letter IATA airline designator. On January 17, 2013, American launched a new rebranding and marketing campaign with FutureBrand dubbed, "A New American". This included a new logo, which includes elements of the 1967 logo. American Airlines faced difficulty obtaining copyright registration for their 2013 logo. On June 3, 2016, American Airlines sought to register it with the United States Copyright Office, but in October of that year, the Copyright Office ruled that the logo was ineligible for copyright protection, as it did not pass the threshold of originality, and was thus in the public domain. American requested that the Copyright Office reconsider, but on January 8, 2018, the Copyright Office affirmed its initial determination. After American Airlines submitted additional materials, the Copyright Office reversed its decision on December 7, 2018, and ruled that the logo contained enough creativity to merit copyright protection. Aircraft livery American's early liveries varied widely, but a common livery was adopted in the 1930s, featuring an eagle painted on the fuselage. The eagle became a symbol of the company and inspired the name of American Eagle Airlines. Propeller aircraft featured an international orange lightning bolt running down the length of the fuselage, which was replaced by a simpler orange stripe with the introduction of jets. In the late 1960s, American commissioned designer Massimo Vignelli to develop a new livery. The original design called for a red, white, and blue stripe on the fuselage, and a simple "AA" logo, without an eagle, on the tail; instead, Vignelli created a highly stylized eagle, which remained the company's logo until January 16, 2013. On January 17, 2013, American unveiled a new livery. Before then, American had been the only major U.S. airline to leave most of its aircraft surfaces unpainted. This was because C. R. Smith would not say he liked painted aircraft and refused to use any liveries that involved painting the entire plane. Robert "Bob" Crandall later justified the distinctive natural metal finish by noting that less paint reduced the aircraft's weight, thus saving on fuel costs. In January 2013, American launched a new rebranding and marketing campaign dubbed, "The New American". In addition to a new logo, American Airlines introduced a new livery for its fleet. The airline calls the new livery and branding "a clean and modern update". The current design features an abstract American flag on the tail, along with a silver-painted fuselage, as a throw-back to the old livery. The new design was painted by Leading Edge Aviation Services in California. Doug Parker, the incoming CEO indicated that the new livery could be short-lived, stating that "maybe we need to do something slightly different than that ... The only reason this is an issue now is that they just did it right in the middle, which kind of makes it confusing, so that gives us an opportunity, actually, to decide if we are going to do something different because we have so many airplanes to paint". The current logo and livery have had mixed criticism, with Design Shack editor Joshua Johnson writing that they "boldly and proudly communicate the concepts of American pride and freedom wrapped into a shape that instantly makes you think about an airplane", and AskThePilot.com author Patrick Smith describing the logo as 'a linoleum knife poking through a shower curtain'. Later in January 2013, Bloomberg asked the designer of the 1968 American Airlines logo (Massimo Vignelli) on his opinion over the rebranding. In the end, American let their employees decide the new livery's fate. On an internal website for employees, American posted two options, one the new livery and one a modified version of the old livery. All of the American Airlines Group employees (including US Airways and other affiliates) were able to vote. American ultimately decided to keep the new look. Parker announced that American would keep a US Airways and America West heritage aircraft in the fleet, with plans to add a heritage TWA aircraft and a heritage American plane with the old livery. As of September 2019, American has heritage aircraft for Piedmont, PSA, America West, US Airways, Reno Air, TWA, and AirCal in their fleet. They also have two AA branded heritage 737-800 aircraft, an AstroJet N905NN, and the polished aluminum livery used from 1967 to 2013, N921NN. Customer Service American, both before and after the merger with US Airways, has consistently performed poorly in rankings. The Wall Street Journal's annual airline rankings have ranked American as the worst or second-worst U.S. carrier for ten of the past twelve years, and in the bottom three of U.S. Airlines for at least the past twelve years. The airline has persistently performed poorly in the areas of losing checked luggage and bumping passengers due to oversold flights. Worker relations The main representatives of key groups of employees are: The Allied Pilots Association is an in-house union which represents the nearly 15,000 American Airlines pilots; it was created in 1963 after the pilots left the Air Line Pilots Association (ALPA). However the majority of American Eagle pilots are ALPA members. The Association of Professional Flight Attendants represents American Airlines flight attendants, including former USAirways flight attendants. Flight attendants at wholly owned regional carriers (Envoy, Piedmont, and PSA) are all represented by Association of Flight Attendants – Communications Workers of America (AFA-CWA). US Airways flight attendants were active members of AFA-CWA before the merger, and they are honorary lifetime members. AFA-CWA is the largest flight attendant union in the industry. The Transport Workers Union-International Association of Machinists alliance (TWU-IAM) represents the majority of American Airlines employed fleet service agents, mechanics, and other ground workers. American's customer service and gate employees belong to the Communications Workers of America/International Brotherhood of Teamsters Passenger Service Association. Concerns and conflicts Environmental violations Between October 1993 to July 1998, American Airlines was repeatedly cited for using high-sulfur fuel in motor vehicles at 10 major airports around the country, a violation of the Clean Air Act. Lifetime AAirpass Since 1981, as a means of creating revenue in a period of loss-making, American Airlines had offered a lifetime pass of unlimited travel, for the initial cost of $250,000. This entitled the pass holder to fly anywhere in the world. Twenty-eight were sold. However, after some time, the airline realized they were making losses on the tickets, with the ticketholders costing them up to $1 million each. Ticketholders were booking large numbers of flights with some ticketholders flying interstate for lunch or flying to London multiple times a month. AA raised the cost of the lifetime pass to $3 million, and then finally stopped offering it in 2003. AA then used litigation to cancel two of the lifetime offers, saying the passes "had been terminated due to fraudulent activity". Cabin fume events In 1988, on American Airlines Flight 132's approach into Nashville, flight attendants notified the cockpit that there was smoke in the cabin. The flight crew in the cockpit ignored the warning, as on a prior flight, a fume event had occurred due to a problem with the auxiliary power unit. However, the smoke on Flight 132 was caused by improperly packaged hazardous materials. According to the NTSB inquiry, the cockpit crew persistently refused to acknowledge that there was a serious threat to the aircraft or the passengers, even after they were told that the floor was becoming soft and passengers had to be reseated. As a result, the aircraft was not evacuated immediately on landing, exposing the crew and passengers to the threat of smoke and fire longer than necessary. On April 11, 2007, toxic smoke and oil fumes leaked into the aircraft cabin as American Airlines Flight 843 taxied to the gate. A flight attendant who was present in the cabin subsequently filed a lawsuit against Boeing, stating that she was diagnosed with neurotoxic disorder due to her exposure to the fumes, which caused her to experience memory loss, tremors, and severe headaches. She settled with the company in 2011. In 2009, Mike Holland, deputy chairman for radiation and environmental issues at the Allied Pilots Association and an American Airlines pilot, said that the pilot union had started alerting pilots of the danger of contaminated bleed air, including contacting crew members that the union thinks were exposed to contamination based on maintenance records and pilot logs. In a January 2017 incident on American Airlines Flight 1896, seven flight attendants were hospitalized after a strange odor was detected in the cabin. The Airbus A330 involved subsequently underwent a "thorough maintenance inspection", having been involved in three fume events in three months. In August 2018, American Airlines flight attendants picketed in front of the Fort Worth company headquarters over a change in sick day policy, complaining that exposure to ill passengers, toxic uniforms, toxic cabin air, radiation exposure, and other issues were causing them to be sick. In January 2019, two pilots and three flight attendants on Flight 1897 from Philadelphia to Fort Lauderdale were hospitalized following complaints of a strange odor. Discrimination complaints On October 24, 2017, the NAACP issued a travel advisory for American Airlines urging African Americans to "exercise caution" when traveling with the airline. The NAACP issued the advisory after four incidents. In one incident, a black woman was moved from first class to coach while her white traveling companion was allowed to remain in first class. In another incident, a black man was forced to give up his seats after being confronted by two unruly white passengers. According to the NAACP, while they did receive complaints on other airlines, most of their complaints in the year before their advisory were on American Airlines. In July 2018, the NAACP lifted their travel advisory saying that American has made improvements to mitigate discrimination and unsafe treatment of African Americans. Accidents and incidents As of March 2019, the airline has had almost sixty aircraft hull losses, beginning with the crash of an American Airways Ford 5-AT-C Trimotor in August 1931. Of these most were propeller driven aircraft, including three Lockheed L-188 Electra turboprop aircraft (of which one, the crash in 1959 of Flight 320, resulted in fatalities). The two accidents with the highest fatalities in both the airline's and U.S. aviation history were Flight 191 in 1979 and Flight 587 in 2001. Out of the 17 hijackings of American Airlines flights, two aircraft were hijacked and destroyed in the September 11 attacks: Flight 11 crashed into the north facade of the North Tower of the World Trade Center, and Flight 77 crashed into the Pentagon; both were bound for LAX from Boston Logan International Airport and Washington Dulles International Airport respectively. Other accidents include the Flight 383 engine failure and fire in 2016. There were two training flight accidents in which the crew were killed and six that resulted in no fatalities. Another four jet aircraft have been written off due to incidents while they were parked between flights or while undergoing maintenance. Carbon footprint American Airlines reported total CO2e emissions (direct and indirect) for the twelve months ending December 31, 2020, at 20,092 Kt (-21,347 /-51.5% y-o-y). The company aims to achieve net zero carbon emissions by 2050.

Antidepressants are a class of medications used to treat major depressive disorder, anxiety disorders, chronic pain, and addiction. Common side effects of antidepressants include dry mouth, weight gain, dizziness, headaches, akathisia, sexual dysfunction, and emotional blunting. There is an increased risk of suicidal thinking and behavior when taken by children, adolescents, and young adults. Discontinuation syndrome, which resembles recurrent depression in the case of the SSRI class, may occur after stopping the intake of any antidepressant, having effects which may be permanent and irreversible. Research regarding the effectiveness of antidepressants for depression in adults is controversial and has found both benefits and drawbacks. Meanwhile, evidence of benefit in children and adolescents is unclear, even though antidepressant use has considerably increased in children and adolescents in the 2000s. While a 2018 study found that the 21 most commonly prescribed antidepressant medications were slightly more effective than placebos for the short-term (acute) treatments of adults with major depressive disorder, other research has found that the placebo effect may account for most or all of the drugs' observed efficacy. Research on the effectiveness of antidepressants is generally done on people who have severe symptoms, a population that exhibits much weaker placebo responses, meaning that the results may not be extrapolated to the general population that has not (or has not yet) been diagnosed with anxiety or depression. Medical uses Antidepressants are prescribed to treat major depressive disorder (MDD), anxiety disorders, chronic pain, and some addictions. Antidepressants are often used in combination with one another. Despite its longstanding prominence in pharmaceutical advertising, the idea that low serotonin levels cause depression is not supported by scientific evidence. Proponents of the monoamine hypothesis of depression recommend choosing an antidepressant which impacts the most prominent symptoms. Under this practice, for example, a person with MDD who is also anxious or irritable would be treated with selective serotonin reuptake inhibitors (SSRIs) or norepinephrine reuptake inhibitors, while a person suffering from loss of energy and enjoyment of life would take a norepinephrine–dopamine reuptake inhibitor. Major depressive disorder The UK National Institute for Health and Care Excellence (NICE)'s 2022 guidelines indicate that antidepressants should not be routinely used for the initial treatment of mild depression, "unless that is the person's preference". The guidelines recommended that antidepressant treatment be considered: For people with a history of moderate or severe depression. For people with mild depression that has been present for an extended period. As a first-line treatment for moderate to severe depression. As a second-line treatment for mild depression that persists after other interventions. The guidelines further note that in most cases, antidepressants should be used in combination with psychosocial interventions and should be continued for at least six months to reduce the risk of relapse and that SSRIs are typically better tolerated than other antidepressants. American Psychiatric Association (APA) treatment guidelines recommend that initial treatment be individually tailored based on factors including the severity of symptoms, co-existing disorders, prior treatment experience, and the person's preference. Options may include antidepressants, psychotherapy, electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), or light therapy. The APA recommends antidepressant medication as an initial treatment choice in people with mild, moderate, or severe major depression, and that should be given to all people with severe depression unless ECT is planned. Reviews of antidepressants generally find that they benefit adults with depression. On the other hand, some contend that most studies on antidepressant medication are confounded by several biases: the lack of an active placebo, which means that many people in the placebo arm of a double-blind study may deduce that they are not getting any true treatment, thus destroying double-blindness; a short follow up after termination of treatment; non-systematic recording of adverse effects; very strict exclusion criteria in samples of patients; studies being paid for by the industry; selective publication of results. This means that the small beneficial effects that are found may not be statistically significant. Among the 21 most commonly prescribed antidepressants, the most effective and well-tolerated are escitalopram, paroxetine, sertraline, agomelatine, and mirtazapine. For children and adolescents with moderate to severe depressive disorder, some evidence suggests fluoxetine (either with or without cognitive behavioral therapy) is the best treatment, but more research is needed to be certain. Sertraline, escitalopram, and duloxetine may also help reduce symptoms. A 2023 systematic review and meta-analysis of randomized controlled trials of antidepressants for major depressive disorder found that the medications provided only small or doubtful benefits in terms of quality of life. Likewise, a 2022 systematic review and meta-analysis of randomized controlled trials of antidepressants for major depressive disorder in children and adolescents found small improvements in quality of life. Quality of life as an outcome measure is often selectively reported in trials of antidepressants. Anxiety disorders For children and adolescents, fluvoxamine is effective in treating a range of anxiety disorders. Fluoxetine, sertraline, and paroxetine can also help with managing various forms of anxiety in children and adolescents. Meta-analyses of published and unpublished trials have found that antidepressants have a placebo-subtracted effect size (standardized mean difference or SMD) in the treatment of anxiety disorders of around 0.3, which equates to a small improvement and is roughly the same magnitude of benefit as their effectiveness in the treatment of depression. The effect size (SMD) for improvement with placebo in trials of antidepressants for anxiety disorders is approximately 1.0, which is a large improvement in terms of effect size definitions. In relation to this, most of the benefit of antidepressants for anxiety disorders is attributable to placebo responses rather than to the effects of the antidepressants themselves. Generalized anxiety disorder Antidepressants are recommended by the National Institute for Health and Care Excellence (NICE) for the treatment of generalized anxiety disorder (GAD) that has failed to respond to conservative measures such as education and self-help activities. GAD is a common disorder in which the central feature is excessively worrying about numerous events. Key symptoms include excessive anxiety about events and issues going on around them and difficulty controlling worrisome thoughts that persists for at least 6 months. Antidepressants provide a modest to moderate reduction in anxiety in GAD. The efficacy of different antidepressants is similar. Social anxiety disorder Some antidepressants are used as a treatment for social anxiety disorder, but their efficacy is not entirely convincing, as only a small proportion of antidepressants showed some effectiveness for this condition. Paroxetine was the first drug to be FDA-approved for this disorder. Its efficacy is considered beneficial, although not everyone responds favorably to the drug. Sertraline and fluvoxamine extended-release were later approved for it as well, while escitalopram is used off-label with acceptable efficiency. However, there is not enough evidence to support Citalopram for treating social anxiety disorder, and fluoxetine was no better than a placebo in clinical trials. SSRIs are used as a first-line treatment for social anxiety, but they do not work for everyone. One alternative would be venlafaxine, an SNRI, which has shown benefits for social phobia in five clinical trials against a placebo, while the other SNRIs are not considered particularly useful for this disorder as many of them did not undergo testing for it. , it is unclear if duloxetine and desvenlafaxine can provide benefits for people with social anxiety. However, another class of antidepressants called MAOIs are considered effective for social anxiety, but they come with many unwanted side effects and are rarely used. Phenelzine was shown to be a good treatment option, but its use is limited by dietary restrictions. Moclobemide is a RIMA and showed mixed results, but still received approval in some European countries for social anxiety disorder. TCA antidepressants, such as clomipramine and imipramine, are not considered effective for this anxiety disorder in particular. This leaves out SSRIs such as paroxetine, sertraline, and fluvoxamine CR as acceptable and tolerated treatment options for this disorder. Obsessive–compulsive disorder SSRIs are a second-line treatment for adult obsessive–compulsive disorder (OCD) with mild functional impairment, and a first-line treatment for those with moderate or severe impairment. In children, SSRIs are considered as a second-line therapy in those with moderate-to-severe impairment, with close monitoring for psychiatric adverse effects. Sertraline and fluoxetine are effective in treating OCD for children and adolescents. Clomipramine, a TCA drug, is considered effective and useful for OCD. However, it is used as a second-line treatment because it is less well-tolerated than SSRIs. Despite this, it has not shown superiority to fluvoxamine in trials. All SSRIs can be used effectively for OCD. SNRI use may also be attempted, though no SNRIs have been approved for the treatment of OCD. Despite these treatment options, many patients remain symptomatic after initiating the medication, and less than half achieve remission. Placebo responses are a large component of the benefit of antidepressants in the treatment of depression and anxiety. However, placebo responses with antidepressants are lower in magnitude in the treatment of OCD compared to depression and anxiety. A 2019 meta-analysis found placebo improvement effect sizes (SMD) of about 1.2 for depression, 1.0 for anxiety disorders, and 0.6 for OCD with antidepressants. Post–traumatic stress disorder Antidepressants are one of the treatment options for PTSD. However, their efficacy is not well established. Paroxetine and sertraline have been FDA approved for the treatment of PTSD. Paroxetine has slightly higher response and remission rates than sertraline for this condition. However, neither drug is considered very helpful for a broad patient demographic. Fluoxetine and venlafaxine are used off-label. Fluoxetine has produced unsatisfactory mixed results. Venlafaxine showed response rates of 78%, which is significantly higher than what paroxetine and sertraline achieved. However, it did not address as many symptoms of PTSD as paroxetine and sertraline, in part due to the fact that venlafaxine is an SNRI. This class of drugs inhibits the reuptake of norepinephrine, which may cause anxiety in some patients. Fluvoxamine, escitalopram, and citalopram were not well-tested for this disorder. MAOIs, while some of them may be helpful, are not used much because of their unwanted side effects. This leaves paroxetine and sertraline as acceptable treatment options for some people, although more effective antidepressants are needed. Panic disorder Panic disorder is treated relatively well with medications compared to other disorders. Several classes of antidepressants have shown efficacy for this disorder, with SSRIs and SNRIs used first-line. Paroxetine, sertraline, and fluoxetine are FDA-approved for panic disorder, while fluvoxamine, escitalopram, and citalopram are also considered effective for them. SNRI venlafaxine is also approved for this condition. Unlike social anxiety and PTSD, some TCAs antidepressants, like clomipramine and imipramine, have shown efficacy for panic disorder. Moreover, the MAOI phenelzine is also considered useful. Panic disorder has many drugs for its treatment. However, the starting dose must be lower than the one used for major depressive disorder because people have reported an increase in anxiety as a result of starting the medication. In conclusion, while panic disorder's treatment options seem acceptable and useful for this condition, many people are still symptomatic after treatment with residual symptoms. Eating disorders Antidepressants are recommended as an alternative or additional first step to self-help programs in the treatment of bulimia nervosa. SSRIs (fluoxetine in particular) are preferred over other antidepressants due to their acceptability, tolerability, and superior reduction of symptoms in short-term trials. Long-term efficacy remains poorly characterized. Bupropion is not recommended for the treatment of eating disorders, due to an increased risk of seizure. Similar recommendations apply to binge eating disorder. SSRIs provide short-term reductions in binge eating behavior, but have not been associated with significant weight loss. Clinical trials have generated mostly negative results for the use of SSRIs in the treatment of anorexia nervosa. Treatment guidelines from the National Institute of Health and Care Excellence (NICE) recommend against the use of SSRIs in this disorder. Those from the American Psychiatric Association (APA) note that SSRIs confer no advantage regarding weight gain, but may be used for the treatment of co-existing depressive, anxiety, or obsessive–compulsive disorders. Pain Fibromyalgia A 2012 meta-analysis concluded that antidepressant treatment favorably affects pain, health-related quality of life, depression, and sleep in fibromyalgia syndrome. Tricyclics appear to be the most effective class, with moderate effects on pain and sleep, and small effects on fatigue and health-related quality of life. The fraction of people experiencing a 30% pain reduction on tricyclics was 48%, versus 28% on placebo. For SSRIs and SNRIs, the fractions of people experiencing a 30% pain reduction were 36% (20% in the placebo comparator arms) and 42% (32% in the corresponding placebo comparator arms) respectively. Discontinuation of treatment due to side effects was common. Antidepressants including amitriptyline, fluoxetine, duloxetine, milnacipran, moclobemide, and pirlindole are recommended by the European League Against Rheumatism (EULAR) for the treatment of fibromyalgia based on "limited evidence". Neuropathic pain A 2014 meta-analysis from the Cochrane Collaboration found the antidepressant duloxetine to be effective for the treatment of pain resulting from diabetic neuropathy. The same group reviewed data for amitriptyline in the treatment of neuropathic pain and found limited useful randomized clinical trial data. They concluded that the long history of successful use in the community for the treatment of fibromyalgia and neuropathic pain justified its continued use. The group was concerned about the potential overestimation of the amount of pain relief provided by amitriptyline, and highlighted that only a small number of people will experience significant pain relief by taking this medication. Other uses Antidepressants may be modestly helpful for treating people who have both depression and alcohol dependence, however, the evidence supporting this association is of low quality. Bupropion is used to help people stop smoking. Antidepressants are also used to control some symptoms of narcolepsy. Antidepressants may be used to relieve pain in people with active rheumatoid arthritis. However, further research is required. Antidepressants have been shown to be superior to placebo in treating depression in individuals with physical illness, although reporting bias may have exaggerated this finding. Limitations and strategies Among individuals treated with a given antidepressant, between 30% and 50% do not show a response. Approximately one-third of people achieve a full remission, one-third experience a response, and one-third are non-responders. Partial remission is characterized by the presence of poorly defined residual symptoms. These symptoms typically include depressed mood, anxiety, sleep disturbance, fatigue, and diminished interest or pleasure. It is currently unclear which factors predict partial remission. However, it is clear that residual symptoms are powerful predictors of relapse, with relapse rates three to six times higher in people with residual symptoms than in those, who experience full remission. In addition, antidepressant drugs tend to lose efficacy throughout long-term maintenance therapy. According to data from the Centers for Disease Control and Prevention, less than one-third of Americans taking one antidepressant medication have seen a mental health professional in the previous year. Several strategies are used in clinical practice to try to overcome these limits and variations. They include switching medication, augmentation, and combination. There is controversy amongst researchers regarding the efficacy and risk-benefit ratio of antidepressants. Although antidepressants consistently out-perform a placebo in meta-analyses, the difference is modest and it is not clear that their statistical superiority results in clinical efficacy. The aggregate effect of antidepressants typically results in changes below the threshold of clinical significance on depression rating scales. Proponents of antidepressants counter that the most common scale, the HDRS, is not suitable for assessing drug action, that the threshold for clinical significance is arbitrary, and that antidepressants consistently result in significantly raised scores on the mood item of the scale. Assessments of antidepressants using alternative, more sensitive scales, such as the MADRS, do not result in marked difference from the HDRS and likewise only find a marginal clinical benefit. Another hypothesis proposed to explain the poor performance of antidepressants in clinical trials is a high treatment response heterogeneity. Some patients, that differ strongly in their response to antidepressants, could influence the average response, while the heterogeneity could itself be obscured by the averaging. Studies have not supported this hypothesis, but it is very difficult to measure treatment effect heterogeneity. Poor and complex clinical trial design might also account for the small effects seen for antidepressants. The randomized controlled trials used to approve drugs are short, and may not capture the full effect of antidepressants. Additionally, the placebo effect might be inflated in these trials by frequent clinical consultation, lowering the comparative performance of antidepressants. Critics agree that current clinical trials are poorly-designed, which limits the knowledge on antidepressant. More naturalistic studies, such as STAR*D, have produced results, which suggest that antidepressants may be less effective in clinical practice than in randomized controlled trials. Critics of antidepressants maintain that the superiority of antidepressants over placebo is the result of systemic flaws in clinical trials and the research literature. Trials conducted with industry involvement tend to produce more favorable results, and accordingly many of the trials included in meta-analyses are at high risk of bias. Additionally, meta-analyses co-authored by industry employees find more favorable results for antidepressants. The results of antidepressant trials are significantly more likely to be published if they are favorable, and unfavorable results are very often left unpublished or misreported, a phenomenon called publication bias or selective publication. Although this issue has diminished with time, it remains an obstacle to accurately assessing the efficacy of antidepressants. Misreporting of clinical trial outcomes and of serious adverse events, such as suicide, is common. Ghostwriting of antidepressant trials is widespread, a practice in which prominent researchers, or so-called key opinion leaders, attach their names to studies actually written by pharmaceutical company employees or consultants. A particular concern is that the psychoactive effects of antidepressants may lead to the unblinding of participants or researchers, enhancing the placebo effect and biasing results. Some have therefore maintained that antidepressants may only be active placebos. When these and other flaws in the research literature are not taken into account, meta-analyses may find inflated results on the basis of poor evidence. Critics contend that antidepressants have not been proven sufficiently effective by RCTs or in clinical practice and that the widespread use of antidepressants is not evidence-based. They also note that adverse effects, including withdrawal difficulties, are likely underreported, skewing clinicians' ability to make risk-benefit judgements. Accordingly, they believe antidepressants are overused, particularly for non-severe depression and conditions in which they are not indicated. Critics charge that the widespread use and public acceptance of antidepressants is the result of pharmaceutical advertising, research manipulation, and misinformation. Current mainstream psychiatric opinion recognizes the limitations of antidepressants but recommends their use in adults with more severe depression as a first-line treatment. Switching antidepressants The American Psychiatric Association 2000 Practice Guideline advises that where no response is achieved within the following six to eight weeks of treatment with an antidepressant, switch to an antidepressant in the same class, and then to a different class. A 2006 meta-analysis review found wide variation in the findings of prior studies: for people who had failed to respond to an SSRI antidepressant, between 12% and 86% showed a response to a new drug. However, the more antidepressants an individual had previously tried, the less likely they were to benefit from a new antidepressant trial. However, a later meta-analysis found no difference between switching to a new drug and staying on the old medication: although 34% of treatment-resistant people responded when switched to the new drug, 40% responded without being switched. Augmentation and combination For a partial response, the American Psychiatric Association (APA) guidelines suggest augmentation or adding a drug from a different class. These include lithium and thyroid augmentation, dopamine agonists, sex steroids, NRIs, glucocorticoid-specific agents, or the newer anticonvulsants. A combination strategy involves adding another antidepressant, usually from a different class to affect other mechanisms. Although this may be used in clinical practice, there is little evidence for the relative efficacy or adverse effects of this strategy. Other tests conducted include the use of psychostimulants as an augmentation therapy. Several studies have shown the efficacy of combining modafinil for treatment-resistant people. It has been used to help combat SSRI-associated fatigue. Long-term use and stopping The effects of antidepressants typically do not continue once the course of medication ends. This results in a high rate of relapse. In 2003, a meta-analysis found that 18% of people who had responded to an antidepressant relapsed while still taking it, compared to 41% whose antidepressant was switched for a placebo. A gradual loss of therapeutic benefit occurs in a minority of people during the course of treatment. A strategy involving the use of pharmacotherapy in the treatment of the acute episode, followed by psychotherapy in its residual phase, has been suggested by some studies. For patients who wish to stop their antidepressants, engaging in brief psychological interventions such as Preventive Cognitive Therapy or mindfulness-based cognitive therapy while tapering down has been found to diminish the risk for relapse. Adverse effects Antidepressants can cause various adverse effects, depending on the individual and the drug in question. Almost any medication involved with serotonin regulation has the potential to cause serotonin toxicity (also known as serotonin syndrome) — an excess of serotonin that can induce mania, restlessness, agitation, emotional lability, insomnia, and confusion as its primary symptoms. Although the condition is serious, it is not particularly common, generally only appearing at high doses or while on other medications. Assuming proper medical intervention has been taken (within about 24 hours) it is rarely fatal. Antidepressants appear to increase the risk of diabetes by about 1.3-fold. MAOIs tend to have pronounced (sometimes fatal) interactions with a wide variety of medications and over-the-counter drugs. If taken with foods that contain very high levels of tyramine (e.g., mature cheese, cured meats, or yeast extracts), they may cause a potentially lethal hypertensive crisis. At lower doses, the person may only experience a headache due to an increase in blood pressure. In response to these adverse effects, a different type of MAOI, the class of reversible inhibitor of monoamine oxidase A (RIMA), has been developed. The primary advantage of RIMAs is that they do not require the person to follow a special diet while being purportedly effective as SSRIs and tricyclics in treating depressive disorders. Tricyclics and SSRI can cause the so-called drug-induced QT prolongation, especially in older adults; this condition can degenerate into a specific type of abnormal heart rhythm called Torsades de points, which can potentially lead to sudden cardiac arrest. Some antidepressants are also believed to increase thoughts of suicidal ideation. Antidepressants have been associated with an increased risk of dementia in older adults. Pregnancy SSRI use in pregnancy has been associated with a variety of risks with varying degrees of proof of causation. As depression is independently associated with negative pregnancy outcomes, determining the extent to which observed associations between antidepressant use and specific adverse outcomes reflect a causative relationship has been difficult in some cases. In other cases, the attribution of adverse outcomes to antidepressant exposure seems fairly clear. SSRI use in pregnancy is associated with an increased risk of spontaneous abortion of about 1.7-fold, and is associated with preterm birth and low birth weight. A systematic review of the risk of major birth defects in antidepressant-exposed pregnancies found a small increase (3% to 24%) in the risk of major malformations and a risk of cardiovascular birth defects that did not differ from non-exposed pregnancies. A study of fluoxetine-exposed pregnancies found a 12% increase in the risk of major malformations that did not reach statistical significance. Other studies have found an increased risk of cardiovascular birth defects among depressed mothers not undergoing SSRI treatment, suggesting the possibility of ascertainment bias, e.g. that worried mothers may pursue more aggressive testing of their infants. Another study found no increase in cardiovascular birth defects and a 27% increased risk of major malformations in SSRI exposed pregnancies. The FDA advises for the risk of birth defects with the use of paroxetine and the MAOI should be avoided. A 2013 systematic review and meta-analysis found that antidepressant use during pregnancy was statistically significantly associated with some pregnancy outcomes, such as gestational age and preterm birth, but not with other outcomes. The same review cautioned that because differences between the exposed and unexposed groups were small, it was doubtful whether they were clinically significant. A neonate (infant less than 28 days old) may experience a withdrawal syndrome from abrupt discontinuation of the antidepressant at birth. Antidepressants can be present in varying amounts in breast milk, but their effects on infants are currently unknown. Moreover, SSRIs inhibit nitric oxide synthesis, which plays an important role in setting the vascular tone. Several studies have pointed to an increased risk of prematurity associated with SSRI use, and this association may be due to an increased risk of pre-eclampsia during pregnancy. Antidepressant-induced mania Another possible problem with antidepressants is the chance of antidepressant-induced mania or hypomania in people with or without a diagnosis of bipolar disorder. Many cases of bipolar depression are very similar to those of unipolar depression. Therefore, the person can be misdiagnosed with unipolar depression and be given antidepressants. Studies have shown that antidepressant-induced mania can occur in 20–40% of people with bipolar disorder. For bipolar depression, antidepressants (most frequently SSRIs) can exacerbate or trigger symptoms of hypomania and mania. Bupropion has been associated with a lower risk of mood switch than other antidepressants. Suicide Studies have shown that the use of antidepressants is correlated with an increased risk of suicidal behavior and thinking (suicidality) in those aged under 25 years old. This problem has been serious enough to warrant government intervention by the US Food and Drug Administration (FDA) to warn of the increased risk of suicidality during antidepressant treatment. According to the FDA, the heightened risk of suicidality occurs within the first one to two months of treatment. The National Institute for Health and Care Excellence (NICE) places the excess risk in the "early stages of treatment". A meta-analysis suggests that the relationship between antidepressant use and suicidal behavior or thoughts is age-dependent. Compared with placebo, the use of antidepressants is associated with an increase in suicidal behavior or thoughts among those 25 years old or younger (OR=1.62). A review of RCTs and epidemiological studies by Healy and Whitaker found an increase in suicidal acts by a factor of 2.4. There is no effect or possibly a mild protective effect among those aged 25 to 64 (OR=0.79). Antidepressant treatment has a protective effect against suicidality among those aged 65 and over (OR=0.37). Sexual dysfunction Sexual side effects are also common with SSRIs, such as loss of sexual drive, failure to reach orgasm, and erectile dysfunction. Although usually reversible, these sexual side-effects can, in rare cases, continue after the drug has been completely withdrawn. In a study of 1,022 outpatients, overall sexual dysfunction with all antidepressants averaged 59.1% with SSRI values between 57% and 73%, mirtazapine 24%, nefazodone 8%, amineptine 7%, and moclobemide 4%. Moclobemide, a selective reversible MAO-A inhibitor, does not cause sexual dysfunction and can lead to an improvement in all aspects of sexual function. Biochemical mechanisms suggested as causative include increased serotonin, particularly affecting 5-HT2 and 5-HT3 receptors; decreased dopamine; decreased norepinephrine; blockade of cholinergic and α1adrenergic receptors; inhibition of nitric oxide synthetase; and elevation of prolactin levels. Mirtazapine is reported to have fewer sexual side effects, most likely because it antagonizes 5-HT2 and 5-HT3 receptors and may, in some cases, reverse sexual dysfunction induced by SSRIs by the same mechanism. Bupropion, a weak NDRI and nicotinic antagonist, may be useful in treating reduced libido as a result of SSRI treatment. Emotional blunting Certain antidepressants may cause emotional blunting, characterized by a reduced intensity of both positive and negative emotions as well as symptoms of apathy, indifference, and amotivation. It may be experienced as either beneficial or detrimental depending on the situation. This side effect has been particularly associated with serotonergic antidepressants like SSRIs and SNRIs but may be less with atypical antidepressants like bupropion, agomelatine, and vortioxetine. Higher doses of antidepressants seem to be more likely to produce emotional blunting than lower doses. Emotional blunting can be decreased by reducing dosage, discontinuing the medication, or switching to a different antidepressant that may have less propensity for causing this side effect. Changes in weight Changes in appetite or weight are common among antidepressants but are largely drug-dependent and related to which neurotransmitters they affect. Mirtazapine and paroxetine, for example, may be associated with weight gain and/or increased appetite, while others (such as bupropion and venlafaxine) achieve the opposite effect. The antihistaminic properties of certain TCA- and TeCA-class antidepressants have been shown to contribute to the common side effects of increased appetite and weight gain associated with these classes of medication. Bone loss A 2021 nationwide cohort study in South Korea observed a link between SSRI use and bone loss, particularly in recent users. The study also stressed the need of further research to better understand these effects. A 2012 review found that SSRIs along with tricyclic antidepressants were associated with a significant increase in the risk of osteoporotic fractures, peaking in the months after initiation, and moving back towards baseline during the year after treatment was stopped. These effects exhibited a dose–response relationship within SSRIs which varied between different drugs of that class. A 2018 meta-analysis of 11 small studies found a reduction in bone density of the lumbar spine in SSRI users which affected older people the most. Risk of death A 2017 meta-analysis found that antidepressants were associated with a significantly increased risk of death (+33%) and new cardiovascular complications (+14%) in the general population. Conversely, risks were not greater in people with existing cardiovascular disease. Discontinuation syndrome Antidepressant discontinuation syndrome, also called antidepressant withdrawal syndrome, is a condition that can occur following the interruption, reduction, or discontinuation of antidepressant medication. The symptoms may include flu-like symptoms, trouble sleeping, nausea, poor balance, sensory changes, and anxiety. The problem usually begins within three days and may last for several months. Rarely psychosis may occur. A discontinuation syndrome can occur after stopping any antidepressant including selective serotonin reuptake inhibitors (SSRIs), serotonin–norepinephrine reuptake inhibitors (SNRIs), and tricyclic antidepressants (TCAs). The risk is greater among those who have taken the medication for longer and when the medication in question has a short half-life. The underlying reason for its occurrence is unclear. The diagnosis is based on the symptoms. Methods of prevention include gradually decreasing the dose among those who wish to stop, though it is possible for symptoms to occur with tapering. Treatment may include restarting the medication and slowly decreasing the dose. People may also be switched to the long-acting antidepressant fluoxetine, which can then be gradually decreased. Approximately 20–50% of people who suddenly stop an antidepressant develop an antidepressant discontinuation syndrome. The condition is generally not serious. Though about half of people with symptoms describe them as severe. Some restart antidepressants due to the severity of the symptoms. Pharmacology Antidepressants act via a large number of different mechanisms of action. This includes serotonin reuptake inhibition (SSRIs, SNRIs, TCAs, vilazodone, vortioxetine), norepinephrine reuptake inhibition (NRIs, SNRIs, TCAs), dopamine reuptake inhibition (bupropion, amineptine, nomifensine), direct modulation of monoamine receptors (vilazodone, vortioxetine, SARIs, agomelatine, TCAs, TeCAs, antipsychotics), monoamine oxidase inhibition (MAOIs), and NMDA receptor antagonism (ketamine, esketamine, dextromethorphan), among others (e.g., brexanolone, tianeptine). Some antidepressants also have additional actions, like sigma receptor modulation (certain SSRIs, TCAs, dextromethorphan) and antagonism of histamine H1 and muscarinic acetylcholine receptors (TCAs, TeCAs). The earliest and most widely known scientific theory of antidepressant action is the monoamine hypothesis, which can be traced back to the 1950s and 1960s. This theory states that depression is due to an imbalance, most often a deficiency, of the monoamine neurotransmitters, namely serotonin, norepinephrine, and/or dopamine. However, serotonin in particular has been implicated, as in the serotonin hypothesis of depression. The monoamine hypothesis was originally proposed based on observations that reserpine, a drug which depletes the monoamine neurotransmitters, produced depressive effects in people, and that certain hydrazine antituberculosis agents like iproniazid, which prevent the breakdown of monoamine neurotransmitters, produced apparent antidepressant effects. Most currently marketed antidepressants, which are monoaminergic in their actions, are theoretically consistent with the monoamine hypothesis. Despite the widespread nature of the monoamine hypothesis, it has a number of limitations: for one, all monoaminergic antidepressants have a delayed onset of action of at least a week; and secondly, many people with depression do not respond to monoaminergic antidepressants. A number of alternative hypotheses have been proposed, including hypotheses involving glutamate, neurogenesis, epigenetics, cortisol hypersecretion, and inflammation, among others. In 2022, a major systematic umbrella review by Joanna Moncrieff and colleagues showed that the serotonin theory of depression was not supported by evidence from a wide variety of areas. The authors concluded that there is no association between serotonin and depression, and that there is no evidence that strongly supports the theory that depression is caused by low serotonin activity or concentrations. Other literature had described the lack of support for the theory previously. In many of the expert responses to the review, it was stated that the monoamine hypothesis had already long been abandoned by psychiatry. This is in spite of about 90% of the general public in Western countries believing the theory to be true and many in the field of psychiatry continuing to promote the theory up to recent times. In addition to the serotonin umbrella review, reviews have found that reserpine, a drug that depletes the monoamine neurotransmitters—including serotonin, norepinephrine, and dopamine—shows no consistent evidence of producing depressive effects. Instead, findings of reserpine and mood are highly mixed, with similar proportions of studies finding that it has no influence on mood, produces depressive effects, or actually has antidepressant effects. In relation to this, the general monoamine hypothesis, as opposed to only the serotonin theory of depression, likewise does not appear to be well-supported by evidence. The serotonin and monoamine hypotheses of depression have been heavily promoted by the pharmaceutical industry (e.g., in advertisements) and by the psychiatric profession at large despite the lack of evidence in support of them. In the case of the pharmaceutical industry, this can be attributed to obvious financial incentives, with the theory creating a bias against non-pharmacological treatments for depression. An alternative theory for antidepressant action proposed by certain academics such as Irving Kirsch and Joanna Moncrieff is that they work largely or entirely via placebo mechanisms. This is supported by meta-analyses of randomized controlled trials of antidepressants for depression, which consistently show that placebo groups in trials improve about 80 to 90% as much as antidepressant groups on average and that antidepressants are only marginally more effective for depression than placebos. The difference between antidepressants and placebo corresponds to an effect size (SMD) of about 0.3, which in turn equates to about a 2- to 3-point additional improvement on the 0–52-point (HRSD) and 0–60-point (MADRS) depression rating scales used in trials. Differences in effectiveness between different antidepressants are small and not clinically meaningful. The small advantage of antidepressants over placebo is often statistically significant and is the basis for their regulatory approval, but is sufficiently modest that its clinical significance is doubtful. Moreover, the small advantage of antidepressants over placebo may simply be a methodological artifact caused by unblinding due to the psychoactive effects and side effects of antidepressants, in turn resulting in enhanced placebo effects and apparent antidepressant efficacy. Placebos have been found to modify the activity of several brain regions and to increase levels of dopamine and endogenous opioids in the reward pathways. It has been argued by Kirsch that although antidepressants may be used efficaciously for depression as active placebos, they are limited by significant pharmacological side effects and risks, and therefore non-pharmacological therapies, such as psychotherapy and lifestyle changes, which can have similar efficacy to antidepressants but do not have their adverse effects, ought to be preferred as treatments in people with depression. The placebo response, or the improvement in scores in the placebo group in clinical trials, is not only due to the placebo effect, but is also due to other phenomena such as spontaneous remission and regression to the mean. Depression tends to have an episodic course, with people eventually recovering even with no medical intervention, and people tend to seek treatment, as well as enroll in clinical trials, when they are feeling their worst. In meta-analyses of trials of depression therapies, Kirsch estimated based on improvement in untreated waiting-list controls that spontaneous remission and regression to the mean only account for about 25% of the improvement in depression scores with antidepressant therapy. However, another academic, Michael P. Hengartner, has argued and presented evidence that spontaneous remission and regression to the mean might actually account for most of the improvement in depression scores with antidepressants, and that the substantial placebo effect observed in clinical trials might largely be a methodological artifact. This suggests that antidepressants may be associated with much less genuine treatment benefit, whether due to the placebo effect or to the antidepressant itself, than has been traditionally assumed. Types Selective serotonin reuptake inhibitors Selective serotonin reuptake inhibitors (SSRIs) are believed to increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption into the presynaptic cell, increasing the level of serotonin in the synaptic cleft available to bind to the postsynaptic receptor. They have varying degrees of selectivity for the other monoamine transporters, with pure SSRIs having only weak affinity for the norepinephrine and dopamine transporters. SSRIs are the most widely prescribed antidepressants in many countries. The efficacy of SSRIs in mild or moderate cases of depression has been disputed. Serotonin–norepinephrine reuptake inhibitors Serotonin–norepinephrine reuptake inhibitors (SNRIs) are potent inhibitors of the reuptake of serotonin and norepinephrine. These neurotransmitters are known to play an important role in mood. SNRIs can be contrasted with the more widely used selective serotonin reuptake inhibitors (SSRIs), which act mostly upon serotonin alone. The human serotonin transporter (SERT) and norepinephrine transporter (NET) are membrane proteins that are responsible for the reuptake of serotonin and norepinephrine. Balanced dual inhibition of monoamine reuptake may offer advantages over other antidepressants drugs by treating a wider range of symptoms. SNRIs are sometimes also used to treat anxiety disorders, obsessive–compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), chronic neuropathic pain, and fibromyalgia syndrome (FMS), and for the relief of menopausal symptoms. Serotonin modulators and stimulators Serotonin modulator and stimulators (SMSs), sometimes referred to more simply as "serotonin modulators", are a type of drug with a multimodal action specific to the serotonin neurotransmitter system. To be precise, SMSs simultaneously modulate one or more serotonin receptors and inhibit the reuptake of serotonin. The term was coined in reference to the mechanism of action of the serotonergic antidepressant vortioxetine, which acts as a serotonin reuptake inhibitor (SRI), a partial agonist of the 5-HT1A receptor, and antagonist of the 5-HT3 and 5-HT7 receptors. However, it can also technically be applied to vilazodone, which is an antidepressant as well and acts as an SRI and 5-HT1A receptor partial agonist. An alternative term is serotonin partial agonist/reuptake inhibitor (SPARI), which can be applied only to vilazodone. Serotonin antagonists and reuptake inhibitors Serotonin antagonist and reuptake inhibitors (SARIs) while mainly used as antidepressants are also anxiolytics and hypnotics. They act by antagonizing serotonin receptors such as 5-HT2A and inhibiting the reuptake of serotonin, norepinephrine, and/or dopamine. Additionally, most also act as α1-adrenergic receptor antagonists. The majority of the currently marketed SARIs belong to the phenylpiperazine class of compounds. They include trazodone and nefazodone. Tricyclic antidepressants The majority of the tricyclic antidepressants (TCAs) act primarily as serotonin–norepinephrine reuptake inhibitors (SNRIs) by blocking the serotonin transporter (SERT) and the norepinephrine transporter (NET), respectively, which results in an elevation of the synaptic concentrations of these neurotransmitters, and therefore an enhancement of neurotransmission. Notably, with the sole exception of amineptine, the TCAs have weak affinity for the dopamine transporter (DAT), and therefore have low efficacy as dopamine reuptake inhibitors (DRIs). Although TCAs are sometimes prescribed for depressive disorders, they have been largely replaced in clinical use in most parts of the world by newer antidepressants such as selective serotonin reuptake inhibitors (SSRIs), serotonin–norepinephrine reuptake inhibitors (SNRIs), and norepinephrine reuptake inhibitors (NRIs). Adverse effects have been found to be of a similar level between TCAs and SSRIs. Tetracyclic antidepressants Tetracyclic antidepressants (TeCAs) are a class of antidepressants that were first introduced in the 1970s. They are named after their chemical structure, which contains four rings of atoms, and are closely related to tricyclic antidepressants (TCAs), which contain three rings of atoms. Monoamine oxidase inhibitors Monoamine oxidase inhibitors (MAOIs) are chemicals that inhibit the activity of the monoamine oxidase enzyme family. They have a long history of use as medications prescribed for the treatment of depression. They are particularly effective in treating atypical depression. They are also used in the treatment of Parkinson's disease and several other disorders. Because of potentially lethal dietary and drug interactions, MAOIs have historically been reserved as a last line of treatment, used only when other classes of antidepressant drugs (for example selective serotonin reuptake inhibitors and tricyclic antidepressants) have failed. MAOIs have been found to be effective in the treatment of panic disorder with agoraphobia, social phobia, atypical depression or mixed anxiety and depression, bulimia, and post-traumatic stress disorder, as well as borderline personality disorder. MAOIs appear to be particularly effective in the management of bipolar depression according to a retrospective-analysis. There are reports of MAOI efficacy in obsessive–compulsive disorder (OCD), trichotillomania, dysmorphophobia, and avoidant personality disorder, but these reports are from uncontrolled case reports. MAOIs can also be used in the treatment of Parkinson's disease by targeting MAO-B in particular (therefore affecting dopaminergic neurons), as well as providing an alternative for migraine prophylaxis. Inhibition of both MAO-A and MAO-B is used in the treatment of clinical depression and anxiety disorders. NMDA receptor antagonists NMDA receptor antagonists like ketamine and esketamine are rapid-acting antidepressants and seem to work via blockade of the ionotropic glutamate NMDA receptor. Other NMDA antagonists may also play a role in treating depression. The combination medication dextromethorphan/bupropion (Auvelity), which contains the NMDA receptor antagonist dextromethorphan, was approved in the United States in 2022 for treating major depressive disorder. Others See the list of antidepressants and management of depression for other drugs that are not specifically characterized. Adjuncts Adjunct medications are an umbrella category of substances that increase the potency or "enhance" antidepressants. They work by affecting variables very close to the antidepressant, sometimes affecting a completely different mechanism of action. This may be attempted when depression treatments have not been successful in the past. Common types of adjunct medication techniques generally fall into the following categories: Two or more antidepressants taken together From the same class (affecting the same area of the brain, often at a much higher level) From different classes (affecting multiple parts of the brain not covered simultaneously by either drug alone) An antipsychotic combined with an antidepressant, particularly atypical antipsychotics such as aripiprazole (Abilify), quetiapine (Seroquel), olanzapine (Zyprexa), and risperidone (Risperdal). It is unknown if undergoing psychological therapy at the same time as taking anti-depressants enhances the anti-depressive effect of the medication. Less common adjuncts Lithium has been used to augment antidepressant therapy in those who have failed to respond to antidepressants alone. Furthermore, Lithium dramatically decreases the suicide risk in recurrent depression. There is some evidence for the addition of a thyroid hormone, triiodothyronine, in patients with normal thyroid function. Psychopharmacologists have also tried adding a stimulant, in particular, D-amphetamine. However, the use of stimulants in cases of treatment-resistant depression is relatively controversial. A review article published in 2007 found psychostimulants may be effective in treatment-resistant depression with concomitant antidepressant therapy, but a more certain conclusion could not be drawn due to substantial deficiencies in the studies available for consideration, and the somewhat contradictory nature of their results. History The idea of an antidepressant, at least if melancholy is thought synonymous with the depression, is at least since the publication of the 1599 pamphlet A pil to purge melancholie or, A preprative to a pvrgation: or, Topping, copping, and capping: take either or whether: or, Mash them, and squash them, and dash them, and diddle come derrie come daw them, all together.., after to this Thomas d'Urfey's Wit and Mirth: Or Pills to Purge Melancholy, the title of a large collection of songs, was published between 1698 and 1720. Before the 1950s, opioids and amphetamines were commonly used as antidepressants. Their use was later restricted due to their addictive nature and side effects. Extracts from the herb St John's wort have been used as a "nerve tonic" to alleviate depression. St John's wort fell out of favor in most countries through the 19th and 20th centuries, except in Germany, where Hypericum extracts were eventually licensed, packaged, and prescribed. Small-scale efficacy trials were carried out in the 1970s and 1980s, and attention grew in the 1990s following a meta-analysis. It remains an over-the-counter drug (OTC) supplement in most countries. Lead contamination associated with its usage has been seen as concerning, as lead levels in women in the United States taking St. John's wort are elevated by about 20% on average. Research continues to investigate its active component hyperforin, and to further understand its mode of action. Isoniazid, iproniazid, and imipramine In 1951, Irving Selikoff and Edward H. Robitzek, working out of Sea View Hospital on Staten Island, began clinical trials on two new anti-tuberculosis agents developed by Hoffman-LaRoche, isoniazid, and iproniazid. Only patients with a poor prognosis were initially treated. Nevertheless, their condition improved dramatically. Selikoff and Robitzek noted "a subtle general stimulation ... the patients exhibited renewed vigor and indeed this occasionally served to introduce disciplinary problems." The promise of a cure for tuberculosis in the Sea View Hospital trials was excitedly discussed in the mainstream press. In 1952, learning of the stimulating side effects of isoniazid, the Cincinnati psychiatrist Max Lurie tried it on his patients. In the following year, he and Harry Salzer reported that isoniazid improved depression in two-thirds of their patients, so they then coined the term antidepressant to refer to its action. A similar incident took place in Paris, where Jean Delay, head of psychiatry at Sainte-Anne Hospital, heard of this effect from his pulmonology colleagues at Cochin Hospital. In 1952 (before Lurie and Salzer), Delay, with the resident Jean-Francois Buisson, reported the positive effect of isoniazid on depressed patients. The mode of antidepressant action of isoniazid is still unclear. It is speculated that its effect is due to the inhibition of diamine oxidase, coupled with a weak inhibition of monoamine oxidase A. Selikoff and Robitzek also experimented with another anti-tuberculosis drug, iproniazid; it showed a greater psychostimulant effect, but more pronounced toxicity. Later, Jackson Smith, Gordon Kamman, George E. Crane, and Frank Ayd, described the psychiatric applications of iproniazid. Ernst Zeller found iproniazid to be a potent monoamine oxidase inhibitor. Nevertheless, iproniazid remained relatively obscure until Nathan S. Kline, the influential head of research at Rockland State Hospital, began to popularize it in the medical and popular press as a "psychic energizer". Roche put a significant marketing effort behind iproniazid. Its sales grew until it was recalled in 1961, due to reports of lethal hepatotoxicity. The antidepressant effect of a tricyclic, a three-ringed compound, was first discovered in 1957 by Roland Kuhn in a Swiss psychiatric hospital. Antihistamine derivatives were used to treat surgical shock and later as neuroleptics. Although in 1955, reserpine was shown to be more effective than a placebo in alleviating anxious depression, neuroleptics were being developed as sedatives and antipsychotics. Attempting to improve the effectiveness of chlorpromazine, Kuhn in conjunction with the Geigy Pharmaceutical Company discovered the compound "G 22355", later renamed imipramine. Imipramine had a beneficial effect on patients with depression who showed mental and motor retardation. Kuhn described his new compound as a "thymoleptic" "taking hold of the emotions," in contrast with neuroleptics, "taking hold of the nerves" in 1955–56. These gradually became established, resulting in the patent and manufacture in the US in 1951 by Häfliger and SchinderA. Antidepressants became prescription drugs in the 1950s. It was estimated that no more than fifty to one hundred individuals per million had the kind of depression that these new drugs would treat, and pharmaceutical companies were not enthusiastic about marketing for this small market. Sales through the 1960s remained poor compared to the sales of tranquilizers, which were being marketed for different uses. Imipramine remained in common use and numerous successors were introduced. The use of monoamine oxidase inhibitors (MAOI) increased after the development and introduction of "reversible" forms affecting only the MAO-A subtype of inhibitors, making this drug safer to use. By the 1960s, it was thought that the mode of action of tricyclics was to inhibit norepinephrine reuptake. However, norepinephrine reuptake became associated with stimulating effects. Later tricyclics were thought to affect serotonin as proposed in 1969 by Carlsson and Lindqvist as well as Lapin and Oxenkrug. Second-generation antidepressants Researchers began a process of rational drug design to isolate antihistamine-derived compounds that would selectively target these systems. The first such compound to be patented was zimelidine in 1971, while the first released clinically was indalpine. Fluoxetine was approved for commercial use by the US Food and Drug Administration (FDA) in 1988, becoming the first blockbuster SSRI. Fluoxetine was developed at Eli Lilly and Company in the early 1970s by Bryan Molloy, Klaus Schmiegel, David T. Wong, and others. SSRIs became known as "novel antidepressants" along with other newer drugs such as SNRIs and NRIs with various selective effects. Rapid-acting antidepressants Esketamine (brand name Spravato), the first rapid-acting antidepressant to be approved for clinical treatment of depression, was introduced for this indication in March 2019 in the United States. Research A 2016 randomized controlled trial evaluated the rapid antidepressant effects of the psychedelic Ayahuasca in treatment-resistant depression with a positive outcome. In 2018, the FDA granted Breakthrough Therapy Designation for psilocybin-assisted therapy for treatment-resistant depression and in 2019, the FDA granted Breakthrough Therapy Designation for psilocybin therapy treating major depressive disorder. Publication bias and aged research A 2018 systematic review published in The Lancet comparing the efficacy of 21 different first and second generation antidepressants found that antidepressant drugs tended to perform better and cause less adverse events when they were novel or experimental treatments compared to when they were evaluated again years later. Unpublished data was also associated with smaller positive effect sizes. However, the review did not find evidence of bias associated with industry funded research. Society and culture Prescription trends United Kingdom In the UK, figures reported in 2010 indicated that the number of antidepressants prescribed by the National Health Service (NHS) almost doubled over a decade. Further analysis published in 2014 showed that number of antidepressants dispensed annually in the community went up by 25 million in the 14 years between 1998 and 2012, rising from 15 million to 40 million. Nearly 50% of this rise occurred in the four years after the 2008 banking crash, during which time the annual increase in prescriptions rose from 6.7% to 8.5%. These sources also suggest that aside from the recession, other factors that may influence changes in prescribing rates may include: improvements in diagnosis, a reduction of the stigma surrounding mental health, broader prescribing trends, GP characteristics, geographical location, and housing status. Another factor that may contribute to increasing consumption of antidepressants is the fact that these medications now are used for other conditions including social anxiety and post-traumatic stress disorder. Between 2005 and 2017, the number of adolescents (12 to 17 years) in England who were prescribed antidepressants has doubled. On the other hand, antidepressant prescriptions for children aged 5–11 in England decreased between 1999 and 2017. From April 2015, prescriptions increased for both age groups (for people aged 0 to 17) and peaked during the first COVID lockdown in March 2020. According to National Institute for Health and Care Excellence (NICE) guidelines, antidepressants for children and adolescents with depression and obsessive-compulsive disorder (OCD) should be prescribed together with therapy and after being assessed by a child and adolescent psychiatrist. However, between 2006 and 2017, only 1 in 4 of 12–17 year-olds who were prescribed an SSRI by their GP had seen a specialist psychiatrist and 1 in 6 has seen a pediatrician. Half of these prescriptions were for depression and 16% for anxiety, the latter not being licensed for treatment with antidepressants. Among the suggested possible reasons why GPs are not following the guidelines are the difficulties of accessing talking therapies, long waiting lists, and the urgency of treatment. According to some researchers, strict adherence to treatment guidelines would limit access to effective medication for young people with mental health problems. United States In the United States, antidepressants were the most commonly prescribed medication in 2013. Of the estimated 16 million "long term" (over 24 months) users, roughly 70 percent are female. , about 16.5% of white people in the United States took antidepressants compared with 5.6% of black people in the United States. United States: The most commonly prescribed antidepressants in the US retail market in 2010 were: Netherlands: In the Netherlands, paroxetine is the most prescribed antidepressant, followed by amitriptyline, citalopram and venlafaxine. Adherence , worldwide, 30% to 60% of people did not follow their practitioner's instructions about taking their antidepressants, and in the US, it appeared that around 50% of people did not take their antidepressants as directed by their practitioner. When people fail to take their antidepressants, there is a greater risk that the drug will not help, that symptoms get worse, that they miss work or are less productive at work, and that the person may be hospitalized. Social science perspective Some academics have highlighted the need to examine the use of antidepressants and other medical treatments in cross-cultural terms, because various cultures prescribe and observe different manifestations, symptoms, meanings, and associations of depression and other medical conditions within their populations. These cross-cultural discrepancies, it has been argued, then have implications on the perceived efficacy and use of antidepressants and other strategies in the treatment of depression in these different cultures. In India, antidepressants are largely seen as tools to combat marginality, promising the individual the ability to reintegrate into society through their use—a view and association not observed in the West. Environmental impacts Because most antidepressants function by inhibiting the reuptake of neurotransmitters serotonin, dopamine, and norepinephrine these drugs can interfere with natural neurotransmitter levels in other organisms impacted by indirect exposure. Antidepressants fluoxetine and sertraline have been detected in aquatic organisms residing in effluent-dominated streams. The presence of antidepressants in surface waters and aquatic organisms has caused concern because ecotoxicological effects on aquatic organisms due to fluoxetine exposure have been demonstrated. Coral reef fish have been demonstrated to modulate aggressive behavior through serotonin. Artificially increasing serotonin levels in crustaceans can temporarily reverse social status and turn subordinates into aggressive and territorial dominant males. Exposure to Fluoxetine has been demonstrated to increase serotonergic activity in fish, subsequently reducing aggressive behavior. Perinatal exposure to Fluoxetine at relevant environmental concentrations has been shown to lead to significant modifications of memory processing in 1-month-old cuttlefish. This impairment may disadvantage cuttlefish and decrease their survival. Somewhat less than 10% of orally administered Fluoxetine is excreted from humans unchanged or as glucuronide.

Analog television is the original television technology that uses analog signals to transmit video and audio. In an analog television broadcast, the brightness, colors and sound are represented by amplitude, phase and frequency of an analog signal. Analog signals vary over a continuous range of possible values which means that electronic noise and interference may be introduced. Thus with analog, a moderately weak signal becomes snowy and subject to interference. In contrast, picture quality from a digital television (DTV) signal remains good until the signal level drops below a threshold where reception is no longer possible or becomes intermittent. Analog television may be wireless (terrestrial television and satellite television) or can be distributed over a cable network as cable television. All broadcast television systems used analog signals before the arrival of DTV. Motivated by the lower bandwidth requirements of compressed digital signals, beginning in the 2000s, a digital television transition is proceeding in most countries of the world, with different deadlines for the cessation of analog broadcasts. Several countries have made the switch already, with the remaining countries still in progress mostly in Africa and Asia. Development The earliest systems of analog television were mechanical television systems that used spinning disks with patterns of holes punched into the disc to scan an image. A similar disk reconstructed the image at the receiver. Synchronization of the receiver disc rotation was handled through sync pulses broadcast with the image information. Camera systems used similar spinning discs and required intensely bright illumination of the subject for the light detector to work. The reproduced images from these mechanical systems were dim, very low resolution and flickered severely. Analog television did not begin in earnest as an industry until the development of the cathode-ray tube (CRT), which uses a focused electron beam to trace lines across a phosphor coated surface. The electron beam could be swept across the screen much faster than any mechanical disc system, allowing for more closely spaced scan lines and much higher image resolution. Also, far less maintenance was required of an all-electronic system compared to a mechanical spinning disc system. All-electronic systems became popular with households after World War II. Standards Broadcasters of analog television encode their signal using different systems. The official systems of transmission were defined by the ITU in 1961 as: A, B, C, D, E, F, G, H, I, K, K1, L, M and N. These systems determine the number of scan lines, frame rate, channel width, video bandwidth, video-audio separation, and so on. A color encoding scheme (NTSC, PAL, or SECAM) could be added to the base monochrome signal. Using RF modulation the signal is then modulated onto a very high frequency (VHF) or ultra high frequency (UHF) carrier wave. Each frame of a television image is composed of scan lines drawn on the screen. The lines are of varying brightness; the whole set of lines is drawn quickly enough that the human eye perceives it as one image. The process repeats and next sequential frame is displayed, allowing the depiction of motion. The analog television signal contains timing and synchronization information so that the receiver can reconstruct a two-dimensional moving image from a one-dimensional time-varying signal. The first commercial television systems were black-and-white; the beginning of color television was in the 1950s. A practical television system needs to take luminance, chrominance (in a color system), synchronization (horizontal and vertical), and audio signals, and broadcast them over a radio transmission. The transmission system must include a means of television channel selection. Analog broadcast television systems come in a variety of frame rates and resolutions. Further differences exist in the frequency and modulation of the audio carrier. The monochrome combinations still existing in the 1950s were standardized by the International Telecommunication Union (ITU) as capital letters A through N. When color television was introduced, the chrominance information was added to the monochrome signals in a way that black and white televisions ignore. In this way backward compatibility was achieved. There are three standards for the way the additional color information can be encoded and transmitted. The first was the American NTSC system. The European and Australian PAL and the French and former Soviet Union SECAM standards were developed later and attempt to cure certain defects of the NTSC system. PAL's color encoding is similar to the NTSC systems. SECAM, though, uses a different modulation approach than PAL or NTSC. PAL had a late evolution called PALplus, allowing widescreen broadcasts while remaining fully compatible with existing PAL equipment. In principle, all three color encoding systems can be used with any scan line/frame rate combination. Therefore, in order to describe a given signal completely, it's necessary to quote the color system plus the broadcast standard as a capital letter. For example, the United States, Canada, Mexico and South Korea use NTSC-M, Japan uses NTSC-J, the UK uses PAL-I, France uses SECAM-L, much of Western Europe and Australia use PAL-B/G, most of Eastern Europe uses SECAM-D/K or PAL-D/K and so on. Not all of the possible combinations exist. NTSC is only used with system M, even though there were experiments with NTSC-A (405 line) in the UK and NTSC-N (625 line) in part of South America. PAL is used with a variety of 625-line standards (B, G, D, K, I, N) but also with the North American 525-line standard, accordingly named PAL-M. Likewise, SECAM is used with a variety of 625-line standards. For this reason, many people refer to any 625/25 type signal as PAL and to any 525/30 signal as NTSC, even when referring to digital signals; for example, on DVD-Video, which does not contain any analog color encoding, and thus no PAL or NTSC signals at all. Although a number of different broadcast television systems are in use worldwide, the same principles of operation apply. Displaying an image A cathode-ray tube (CRT) television displays an image by scanning a beam of electrons across the screen in a pattern of horizontal lines known as a raster. At the end of each line, the beam returns to the start of the next line; at the end of the last line, the beam returns to the beginning of the first line at the top of the screen. As it passes each point, the intensity of the beam is varied, varying the luminance of that point. A color television system is similar except there are three beams that scan together and an additional signal known as chrominance controls the color of the spot. When analog television was developed, no affordable technology for storing video signals existed; the luminance signal had to be generated and transmitted at the same time at which it is displayed on the CRT. It was therefore essential to keep the raster scanning in the camera (or other device for producing the signal) in exact synchronization with the scanning in the television. The physics of the CRT require that a finite time interval be allowed for the spot to move back to the start of the next line (horizontal retrace) or the start of the screen (vertical retrace). The timing of the luminance signal must allow for this. The human eye has a characteristic called phi phenomenon. Quickly displaying successive scan images creates the illusion of smooth motion. Flickering of the image can be partially solved using a long persistence phosphor coating on the CRT so that successive images fade slowly. However, slow phosphor has the negative side-effect of causing image smearing and blurring when there is rapid on-screen motion occurring. The maximum frame rate depends on the bandwidth of the electronics and the transmission system, and the number of horizontal scan lines in the image. A frame rate of 25 or 30 hertz is a satisfactory compromise, while the process of interlacing two video fields of the picture per frame is used to build the image. This process doubles the apparent number of video frames per second and further reduces flicker and other defects in transmission. Receiving signals The television system for each country will specify a number of television channels within the UHF or VHF frequency ranges. A channel actually consists of two signals: the picture information is transmitted using amplitude modulation on one carrier frequency, and the sound is transmitted with frequency modulation at a frequency at a fixed offset (typically 4.5 to 6 MHz) from the picture signal. The channel frequencies chosen represent a compromise between allowing enough bandwidth for video (and hence satisfactory picture resolution), and allowing enough channels to be packed into the available frequency band. In practice a technique called vestigial sideband is used to reduce the channel spacing, which would be nearly twice the video bandwidth if pure AM was used. Signal reception is invariably done via a superheterodyne receiver: the first stage is a tuner which selects a television channel and frequency-shifts it to a fixed intermediate frequency (IF). The signal amplifier performs amplification to the IF stages from the microvolt range to fractions of a volt. Extracting the sound At this point the IF signal consists of a video carrier signal at one frequency and the sound carrier at a fixed offset in frequency. A demodulator recovers the video signal. Also at the output of the same demodulator is a new frequency modulated sound carrier at the offset frequency. In some sets made before 1948, this was filtered out, and the sound IF of about 22 MHz was sent to an FM demodulator to recover the basic sound signal. In newer sets, this new carrier at the offset frequency was allowed to remain as intercarrier sound, and it was sent to an FM demodulator to recover the basic sound signal. One particular advantage of intercarrier sound is that when the front panel fine tuning knob is adjusted, the sound carrier frequency does not change with the tuning, but stays at the above-mentioned offset frequency. Consequently, it is easier to tune the picture without losing the sound. So the FM sound carrier is then demodulated, amplified, and used to drive a loudspeaker. Until the advent of the NICAM and MTS systems, television sound transmissions were monophonic. Structure of a video signal The video carrier is demodulated to give a composite video signal containing luminance, chrominance and synchronization signals. The result is identical to the composite video format used by analog video devices such as VCRs or CCTV cameras. To ensure good linearity and thus fidelity, consistent with affordable manufacturing costs of transmitters and receivers, the video carrier is never modulated to the extent that it is shut off altogether. When intercarrier sound was introduced later in 1948, not completely shutting off the carrier had the side effect of allowing intercarrier sound to be economically implemented. Each line of the displayed image is transmitted using a signal as shown above. The same basic format (with minor differences mainly related to timing and the encoding of color) is used for PAL, NTSC, and SECAM television systems. A monochrome signal is identical to a color one, with the exception that the elements shown in color in the diagram (the colorburst, and the chrominance signal) are not present. The front porch is a brief (about 1.5 microsecond) period inserted between the end of each transmitted line of picture and the leading edge of the next line's sync pulse. Its purpose was to allow voltage levels to stabilise in older televisions, preventing interference between picture lines. The front porch is the first component of the horizontal blanking interval which also contains the horizontal sync pulse and the back porch. The back porch is the portion of each scan line between the end (rising edge) of the horizontal sync pulse and the start of active video. It is used to restore the black level (300 mV) reference in analog video. In signal processing terms, it compensates for the fall time and settling time following the sync pulse. In color television systems such as PAL and NTSC, this period also includes the colorburst signal. In the SECAM system, it contains the reference subcarrier for each consecutive color difference signal in order to set the zero-color reference. In some professional systems, particularly satellite links between locations, the digital audio is embedded within the line sync pulses of the video signal, to save the cost of renting a second channel. The name for this proprietary system is Sound-in-Syncs. Monochrome video signal extraction The luminance component of a composite video signal varies between 0 V and approximately 0.7 V above the black level. In the NTSC system, there is a blanking signal level used during the front porch and back porch, and a black signal level 75 mV above it; in PAL and SECAM these are identical. In a monochrome receiver, the luminance signal is amplified to drive the control grid in the electron gun of the CRT. This changes the intensity of the electron beam and therefore the brightness of the spot being scanned. Brightness and contrast controls determine the DC shift and amplification, respectively. Color video signal extraction U and V signals A color signal conveys picture information for each of the red, green, and blue components of an image. However, these are not simply transmitted as three separate signals, because: such a signal would not be compatible with monochrome receivers, an important consideration when color broadcasting was first introduced. It would also occupy three times the bandwidth of existing television, requiring a decrease in the number of television channels available. Instead, the RGB signals are converted into YUV form, where the Y signal represents the luminance of the colors in the image. Because the rendering of colors in this way is the goal of both monochrome film and television systems, the Y signal is ideal for transmission as the luminance signal. This ensures a monochrome receiver will display a correct picture in black and white, where a given color is reproduced by a shade of gray that correctly reflects how light or dark the original color is. The U and V signals are color difference signals. The U signal is the difference between the B signal and the Y signal, also known as B minus Y (B-Y), and the V signal is the difference between the R signal and the Y signal, also known as R minus Y (R-Y). The U signal then represents how purplish-blue or its complementary color, yellowish-green, the color is, and the V signal how purplish-red or it's complementary, greenish-cyan, it is. The advantage of this scheme is that the U and V signals are zero when the picture has no color content. Since the human eye is more sensitive to detail in luminance than in color, the U and V signals can be transmitted with reduced bandwidth with acceptable results. In the receiver, a single demodulator can extract an additive combination of U plus V. An example is the X demodulator used in the X/Z demodulation system. In that same system, a second demodulator, the Z demodulator, also extracts an additive combination of U plus V, but in a different ratio. The X and Z color difference signals are further matrixed into three color difference signals, (R-Y), (B-Y), and (G-Y). The combinations of usually two, but sometimes three demodulators were: In the end, further matrixing of the above color-difference signals c through f yielded the three color-difference signals, (R-Y), (B-Y), and (G-Y). The R, G, and B signals in the receiver needed for the display device (CRT, Plasma display, or LCD display) are electronically derived by matrixing as follows: R is the additive combination of (R-Y) with Y, G is the additive combination of (G-Y) with Y, and B is the additive combination of (B-Y) with Y. All of this is accomplished electronically. It can be seen that in the combining process, the low-resolution portion of the Y signals cancel out, leaving R, G, and B signals able to render a low-resolution image in full color. However, the higher resolution portions of the Y signals do not cancel out, and so are equally present in R, G, and B, producing the higher-resolution image detail in monochrome, although it appears to the human eye as a full-color and full-resolution picture. NTSC and PAL systems In the NTSC and PAL color systems, U and V are transmitted by using quadrature amplitude modulation of a subcarrier. This kind of modulation applies two independent signals to one subcarrier, with the idea that both signals will be recovered independently at the receiving end. For NTSC, the subcarrier is at 3.58 MHz. For the PAL system it is at 4.43 MHz. The subcarrier itself is not included in the modulated signal (suppressed carrier), it is the subcarrier sidebands that carry the U and V information. The usual reason for using suppressed carrier is that it saves on transmitter power. In this application a more important advantage is that the color signal disappears entirely in black and white scenes. The subcarrier is within the bandwidth of the main luminance signal and consequently can cause undesirable artifacts on the picture, all the more noticeable in black and white receivers. A small sample of the subcarrier, the colorburst, is included in the horizontal blanking portion, which is not visible on the screen. This is necessary to give the receiver a phase reference for the modulated signal. Under quadrature amplitude modulation the modulated chrominance signal changes phase as compared to its subcarrier and also changes amplitude. The chrominance amplitude (when considered together with the Y signal) represents the approximate saturation of a color, and the chrominance phase against the subcarrier reference approximately represents the hue of the color. For particular test colors found in the test color bar pattern, exact amplitudes and phases are sometimes defined for test and troubleshooting purposes only. Due to the nature of the quadrature amplitude modulation process that created the chrominance signal, at certain times, the signal represents only the U signal, and 70 nanoseconds (NTSC) later, it represents only the V signal. About 70 nanoseconds later still, -U, and another 70 nanoseconds, -V. So to extract U, a synchronous demodulator is utilized, which uses the subcarrier to briefly gate the chroma every 280 nanoseconds, so that the output is only a train of discrete pulses, each having an amplitude that is the same as the original U signal at the corresponding time. In effect, these pulses are discrete-time analog samples of the U signal. The pulses are then low-pass filtered so that the original analog continuous-time U signal is recovered. For V, a 90-degree shifted subcarrier briefly gates the chroma signal every 280 nanoseconds, and the rest of the process is identical to that used for the U signal. Gating at any other time than those times mentioned above will yield an additive mixture of any two of U, V, -U, or -V. One of these off-axis (that is, of the U and V axis) gating methods is called I/Q demodulation. Another much more popular off-axis scheme was the X/Z demodulation system. Further matrixing recovered the original U and V signals. This scheme was actually the most popular demodulator scheme throughout the 1960s. The above process uses the subcarrier. But as previously mentioned, it was deleted before transmission, and only the chroma is transmitted. Therefore, the receiver must reconstitute the subcarrier. For this purpose, a short burst of the subcarrier, known as the colorburst, is transmitted during the back porch (re-trace blanking period) of each scan line. A subcarrier oscillator in the receiver locks onto this signal (see phase-locked loop) to achieve a phase reference, resulting in the oscillator producing the reconstituted subcarrier. NTSC uses this process unmodified. Unfortunately, this often results in poor color reproduction due to phase errors in the received signal, caused sometimes by multipath, but mostly by poor implementation at the studio end. With the advent of solid-state receivers, cable TV, and digital studio equipment for conversion to an over-the-air analog signal, these NTSC problems have been largely fixed, leaving operator error at the studio end as the sole color rendition weakness of the NTSC system. In any case, the PAL D (delay) system mostly corrects these kinds of errors by reversing the phase of the signal on each successive line, and averaging the results over pairs of lines. This process is achieved by the use of a 1H (where H = horizontal scan frequency) duration delay line. Phase shift errors between successive lines are therefore canceled out and the wanted signal amplitude is increased when the two in-phase (coincident) signals are re-combined. NTSC is more spectrum efficient than PAL, giving more picture detail for a given bandwidth. This is because sophisticated comb filters in receivers are more effective with NTSC's 4 color frame sequence compared to PAL's 8-field sequence. However, in the end, the larger channel width of most PAL systems in Europe still gives PAL systems the edge in transmitting more picture detail. SECAM system In the SECAM television system, U and V are transmitted on alternate lines, using simple frequency modulation of two different color subcarriers. In some analog color CRT displays, starting in 1956, the brightness control signal (luminance) is fed to the cathode connections of the electron guns, and the color difference signals (chrominance signals) are fed to the control grids connections. This simple CRT matrix mixing technique was replaced in later solid state designs of signal processing with the original matrixing method used in the 1954 and 1955 color TV receivers. Synchronization Synchronizing pulses added to the video signal at the end of every scan line and video frame ensure that the sweep oscillators in the receiver remain locked in step with the transmitted signal so that the image can be reconstructed on the receiver screen. A sync separator circuit detects the sync voltage levels and sorts the pulses into horizontal and vertical sync. Horizontal synchronization The horizontal sync pulse, separates the scan lines. The horizontal sync signal is a single short pulse that indicates the start of every line. The rest of the scan line follows, with the signal ranging from 0.3 V (black) to 1 V (white), until the next horizontal or vertical synchronization pulse. The format of the horizontal sync pulse varies. In the 525-line NTSC system it is a 4.85 μs pulse at 0 V. In the 625-line PAL system the pulse is 4.7 μs at 0 V. This is lower than the amplitude of any video signal (blacker than black) so it can be detected by the level-sensitive sync separator circuit of the receiver. Two-timing intervals are defined – the front porch between the end of the displayed video and the start of the sync pulse, and the back porch after the sync pulse and before the displayed video. These and the sync pulse itself are called the horizontal blanking (or retrace) interval and represent the time that the electron beam in the CRT is returning to the start of the next display line. Vertical synchronization Vertical synchronization separates the video fields. In PAL and NTSC, the vertical sync pulse occurs within the vertical blanking interval. The vertical sync pulses are made by prolonging the length of horizontal sync pulses through almost the entire length of the scan line. The vertical sync signal is a series of much longer pulses, indicating the start of a new field. The sync pulses occupy the whole line interval of a number of lines at the beginning and end of a scan; no picture information is transmitted during vertical retrace. The pulse sequence is designed to allow horizontal sync to continue during vertical retrace; it also indicates whether each field represents even or odd lines in interlaced systems (depending on whether it begins at the start of a horizontal line, or midway through). The format of such a signal in 525-line NTSC is: pre-equalizing pulses (6 to start scanning odd lines, 5 to start scanning even lines) long-sync pulses (5 pulses) post-equalizing pulses (5 to start scanning odd lines, 4 to start scanning even lines) Each pre- or post-equalizing pulse consists of half a scan line of black signal: 2 μs at 0 V, followed by 30 μs at 0.3 V. Each long sync pulse consists of an equalizing pulse with timings inverted: 30 μs at 0  V, followed by 2 μs at 0.3  V. In video production and computer graphics, changes to the image are often performed during the vertical blanking interval to avoid visible discontinuity of the image. If this image in the framebuffer is updated with a new image while the display is being refreshed, the display shows a mishmash of both frames, producing page tearing partway down the image. Horizontal and vertical hold The sweep (or deflection) oscillators were designed to run without a signal from the television station (or VCR, computer, or other composite video source). This allows the television receiver to display a raster and to allow an image to be presented during antenna placement. With sufficient signal strength, the receiver's sync separator circuit would split timebase pulses from the incoming video and use them to reset the horizontal and vertical oscillators at the appropriate time to synchronize with the signal from the station. The free-running oscillation of the horizontal circuit is especially critical, as the horizontal deflection circuits typically power the flyback transformer (which provides acceleration potential for the CRT) as well as the filaments for the high voltage rectifier tube and sometimes the filament(s) of the CRT itself. Without the operation of the horizontal oscillator and output stages in these television receivers, there would be no illumination of the CRT's face. The lack of precision timing components in early equipment meant that the timebase circuits occasionally needed manual adjustment. If their free-run frequencies were too far from the actual line and field rates, the circuits would not be able to follow the incoming sync signals. Loss of horizontal synchronization usually resulted in an unwatchable picture; loss of vertical synchronization would produce an image rolling up or down the screen. Older analog television receivers often provide manual controls to adjust horizontal and vertical timing. The adjustment takes the form of horizontal hold and vertical hold controls, usually on the front panel along with other common controls. These adjust the free-run frequencies of the corresponding timebase oscillators. A slowly rolling vertical picture demonstrates that the vertical oscillator is nearly synchronized with the television station but is not locking to it, often due to a weak signal or a failure in the sync separator stage not resetting the oscillator. Horizontal sync errors cause the image to be torn diagonally and repeated across the screen as if it were wrapped around a screw or a barber's pole; the greater the error, the more copies of the image will be seen at once wrapped around the barber pole. By the early 1980s the efficacy of the synchronization circuits, plus the inherent stability of the sets' oscillators, had been improved to the point where these controls were no longer necessary. Integrated Circuits which eliminated the horizontal hold control were starting to appear as early as 1969. The final generations of analog television receivers used IC-based designs where the receiver's timebases were derived from accurate crystal oscillators. With these sets, adjustment of the free-running frequency of either sweep oscillator was unnecessary and unavailable. Horizontal and vertical hold controls were rarely used in CRT-based computer monitors, as the quality and consistency of components were quite high by the advent of the computer age, but might be found on some composite monitors used with the 1970s–80s home or personal computers. Other technical information Components of a television system The tuner is the object which, with the aid of an antenna, isolates the television signals received over the air. There are two types of tuners in analog television, VHF and UHF tuners. The VHF tuner selects the VHF television frequency. This consists of a 4 MHz video bandwidth and a 2 MHz audio bandwidth. It then amplifies the signal and converts it to a 45.75 MHz Intermediate Frequency (IF) amplitude-modulated video and a 41.25 MHz IF frequency-modulated audio carrier. The IF amplifiers are centered at 44 MHz for optimal frequency transference of the audio and video carriers. Like radio, television has automatic gain control (AGC). This controls the gain of the IF amplifier stages and the tuner. The video amp and output amplifier is implemented using a pentode or a power transistor. The filter and demodulator separates the 45.75 MHz video from the 41.25 MHz audio then it simply uses a diode to detect the video signal. After the video detector, the video is amplified and sent to the sync separator and then to the picture tube. The audio signal goes to a 4.5 MHz amplifier. This amplifier prepares the signal for the 4.5Mhz detector. It then goes through a 4.5 MHz IF transformer to the detector. In television, there are 2 ways of detecting FM signals. One way is by the ratio detector. This is simple but very hard to align. The next is a relatively simple detector. This is the quadrature detector. It was invented in 1954. The first tube designed for this purpose was the 6BN6 type. It is easy to align and simple in circuitry. It was such a good design that it is still being used today in the Integrated circuit form. After the detector, it goes to the audio amplifier. The next part is the sync separator and clipper. From the detected video signal, this circuit extracts and conditions signals that the horizontal and vertical oscillators can use to keep in sync with the video. It also forms the AGC voltage, as previously stated. The horizontal and vertical oscillators form the raster on the CRT. They are driven by the sync separator. There are many ways to create these oscillators. The earliest is the thyratron oscillator. Although it is known to drift, it makes a perfect sawtooth wave. This sawtooth wave is so good that no linearity control is needed. This oscillator was designed for the electrostatic deflection CRTs but also found some use in electromagnetically deflected CRTs. The next oscillator developed was the blocking oscillator which uses a transformer to create a sawtooth wave. This was only used for a brief time period and never was very popular. Finally the multivibrator was probably the most successful. It needed more adjustment than the other oscillators, but it is very simple and effective. This oscillator was so popular that it was used from the early 1950s until today. Two oscillator amplifiers are neede. The vertical amplifier directly drives the yoke. Since it operates at 50 or 60 Hz and drives an electromagnet, it is similar to an audio amplifier. Because of the rapid deflection required, the horizontal oscillator requires a high-power flyback transformer driven by a high-powered tube or transistor. Additional windings on this flyback transformer typically power other parts of the system. Sync separator Image synchronization is achieved by transmitting negative-going pulses. The horizontal sync signal is a single short pulse that indicates the start of every line. Two-timing intervals are defined – the front porch between the end of the displayed video and the start of the sync pulse, and the back porch after the sync pulse and before the displayed video. These and the sync pulse itself are called the horizontal blanking (or retrace) interval and represent the time that the electron beam in the CRT is returning to the start of the next display line. The vertical sync signal is a series of much longer pulses, indicating the start of a new field. The vertical sync pulses occupy the whole of line interval of a number of lines at the beginning and end of a scan; no picture information is transmitted during vertical retrace. The pulse sequence is designed to allow horizontal sync to continue during vertical retrace. In the television receiver, a sync separator circuit detects the sync voltage levels and sorts the pulses into horizontal and vertical sync. Loss of horizontal synchronization usually resulted in an unwatchable picture; loss of vertical synchronization would produce an image rolling up or down the screen. Counting sync pulses, a video line selector picks a selected line from a TV signal, used for teletext, on-screen displays, station identification logos as well as in the industry when cameras were used as a sensor. Timebase circuits In an analog receiver with a CRT display sync pulses are fed to horizontal and vertical timebase circuits (commonly called "sweep circuits" in the United States), each consisting of an oscillator and an amplifier. These generate modified sawtooth and parabola current waveforms to scan the electron beam in a linear way. The waveform shapes are necessary to make up for the distance variations from the electron beam source and the screen surface. The oscillators are designed to free-run at frequencies very close to the field and line rates, but the sync pulses cause them to reset at the beginning of each scan line or field, resulting in the necessary synchronization of the beam sweep with the originating signal. The output waveforms from the timebase amplifiers are fed to the horizontal and vertical deflection coils wrapped around the CRT tube. These coils produce magnetic fields proportional to the changing current, and these deflect the electron beam across the screen. In the 1950s, the power for these circuits was derived directly from the mains supply. A simple circuit consisted of a series voltage dropper resistance and a rectifier valve (tube) or semiconductor diode. This avoided the cost of a large high voltage mains supply (50 or 60 Hz) transformer. This type of circuit was used for the thermionic valve (vacuum tube) technology. It was inefficient and produced a lot of heat which led to premature failures in the circuitry. Although failure was common, it was easily repairable. In the 1960s, semiconductor technology was introduced into timebase circuits. During the late 1960s in the UK, synchronous (with the scan line rate) power generation was introduced into solid state receiver designs. These had very complex circuits in which faults were difficult to trace, but had very efficient use of power. In the early 1970s AC mains (50 or 60 Hz), and line timebase (15,625 Hz), thyristor based switching circuits were introduced. In the UK use of the simple (50  Hz) types of power, circuits were discontinued. The reason for design changes arose from the electricity supply contamination problems arising from EMI, and supply loading issues due to energy being taken from only the positive half cycle of the mains supply waveform. CRT flyback power supply Most of the receiver's circuitry (at least in transistor- or IC-based designs) operates from a comparatively low-voltage DC power supply. However, the anode connection for a cathode-ray tube requires a very high voltage (typically 10–30 kV) for correct operation. This voltage is not directly produced by the main power supply circuitry; instead, the receiver makes use of the circuitry used for horizontal scanning. Direct current (DC), is switched through the line output transformer, and alternating current (AC) is induced into the scan coils. At the end of each horizontal scan line the magnetic field, which has built up in both transformer and scan coils by the current, is a source of latent electromagnetic energy. This stored collapsing magnetic field energy can be captured. The reverse flow, short duration, (about 10% of the line scan time) current from both the line output transformer and the horizontal scan coil is discharged again into the primary winding of the flyback transformer by the use of a rectifier which blocks this negative reverse emf. A small value capacitor is connected across the scan switching device. This tunes the circuit inductances to resonate at a much higher frequency. This slows down (lengthens) the flyback time from the extremely rapid decay rate that would result if they were electrically isolated during this short period. One of the secondary windings on the flyback transformer then feeds this brief high-voltage pulse to a Cockcroft–Walton generator design voltage multiplier. This produces the required EHT supply. A flyback converter is a power supply circuit operating on similar principles. A typical modern design incorporates the flyback transformer and rectifier circuitry into a single unit with a captive output lead, (known as a diode split line output transformer or an Integrated High Voltage Transformer (IHVT)), so that all high-voltage parts are enclosed. Earlier designs used a separate line output transformer and a well-insulated high voltage multiplier unit. The high frequency (15 kHz or so) of the horizontal scanning allows reasonably small components to be used. Transition to digital In many countries, over-the-air broadcast television of analog audio and analog video signals has been discontinued, to allow the re-use of the television broadcast radio spectrum for other services such as datacasting and subchannels. The first country to make a wholesale switch to digital over-the-air (terrestrial television) broadcasting was Luxembourg in 2006, followed later in 2006 by the Netherlands; in 2007 by Finland, Andorra, Sweden and Switzerland; in 2008 by Belgium (Flanders) and Germany; in 2009 by the United States (high power stations), southern Canada, the Isle of Man, Norway, and Denmark. In 2010, Belgium (Wallonia), Spain, Wales, Latvia, Estonia, the Channel Islands, San Marino, Croatia, and Slovenia; in 2011 Israel, Austria, Monaco, Cyprus, Japan (excluding Miyagi, Iwate, and Fukushima prefectures), Malta and France; in 2012 the Czech Republic, Arab World, Taiwan, Portugal, Japan (including Miyagi, Iwate, and Fukushima prefectures), Serbia, Italy, Canada, Mauritius, the United Kingdom, the Republic of Ireland, Lithuania, Slovakia, Gibraltar, and South Korea; in 2013, the Republic of Macedonia, Poland, Bulgaria, Hungary, Australia, and New Zealand, completed the transition. The United Kingdom made the transition to digital television between 2008 and 2012, with the exception of Whitehaven, which made the switch over in 2007. The first digital TV-only area in the United Kingdom was Ferryside in Carmarthenshire. The Digital television transition in the United States for high-powered transmission was completed on 12 June 2009, the date that the Federal Communications Commission (FCC) set. Almost two million households could no longer watch television because they had not prepared for the transition. The switchover had been delayed by the DTV Delay Act. While the majority of the viewers of over-the-air broadcast television in the U.S. watch full-power stations (which number about 1800), there are three other categories of television stations in the U.S.: low-power broadcasting stations, class A stations, and television translator stations. They were given later deadlines. In broadcasting, the United States influences southern Canada and northern Mexico because those areas are covered by television stations in the U.S. In Japan, the switch to digital began in northeastern Ishikawa Prefecture on 24 July 2010 and ended in 43 of the country's 47 prefectures (including the rest of Ishikawa) on 24 July 2011, but in Fukushima, Iwate, and Miyagi prefectures, the conversion was delayed to 31 March 2012, due to complications from the 2011 Tōhoku earthquake and tsunami and its related nuclear accidents. In Canada, most of the larger cities turned off analog broadcasts on 31 August 2011. China had scheduled to end analog broadcasting between 2015 and 2018. Brazil switched to digital television on 2 December 2007 in its major cities. It is estimated that Brazil will end analog broadcasting in 2023. In Malaysia, the Malaysian Communications & Multimedia Commission (MCMC) advertised for tender bids to be submitted in the third quarter of 2009 for the 470 through 742  MHz UHF allocation, to enable Malaysia's broadcast system to move into DTV. The new broadcast band allocation would result in Malaysia's having to build an infrastructure for all broadcasters, using a single digital terrestrial transmission/television broadcast (DTTB) channel. Large portions of Malaysia are covered by television broadcasts from Singapore, Thailand, Brunei, and Indonesia (from Borneo and Batam). Starting from 1 November 2019, all regions in Malaysia were no longer using the analog system after the states of Sabah and Sarawak finally turned it off on 31 October 2019. In Singapore, digital television under DVB-T2 began on 16 December 2013. The switchover was delayed many times until analog TV was switched off at midnight on 2 January 2019. In the Philippines, the National Telecommunications Commission required all broadcasting companies to end analog broadcasting on 31 December 2015 at 11:59 p.m. Due to delay of the release of the implementing rules and regulations for digital television broadcast, the target date was moved to 2020. Full digital broadcast is expected in 2021 and all of the analog TV services should be shut down by the end of 2023. In the Russian Federation, the Russian Television and Radio Broadcasting Network (RTRS) disabled analog broadcasting of federal channels in five stages, shutting down broadcasting in multiple federal subjects at each stage. The first region to have analog broadcasting disabled was Tver Oblast on 3 December 2018, and the switchover was completed on 14 October 2019. During the transition, DVB-T2 receivers and monetary compensations for purchasing of terrestrial or satellite digital TV reception equipment were provided to disabled people, World War II veterans, certain categories of retirees and households with income per member below living wage.

Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, or welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. Adhesives are typically organized by the method of adhesion followed by reactive or non-reactive, a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized either by their starting physical phase or whether their raw stock is of natural or synthetic origin. Adhesives may be found naturally or produced synthetically. The earliest human use of adhesive-like substances was approximately 200,000 years ago, when Neanderthals produced tar from the dry distillation of birch bark for use in binding stone tools to wooden handles. The first references to adhesives in literature appeared in approximately 2000 BC. The Greeks and Romans made great contributions to the development of adhesives. In Europe, glue was not widely used until the period AD 1500–1700. From then until the 1900s increases in adhesive use and discovery were relatively gradual. Only since the 20th century has the development of synthetic adhesives accelerated rapidly, and innovation in the field continues to the present. History Evidence of the earliest known use of adhesives was discovered in central Italy when two stone flakes partially covered with birch-bark tar and a third uncovered stone from the Middle Pleistocene era (circa 200,000 years ago) were found. This is thought to be the oldest discovered human use of tar-hafted stones. The birch-bark-tar adhesive is a simple, one-component adhesive. A study from 2019 showed that birch tar production can be a very simple process—merely involving the burning of birch bark near smooth vertical surfaces in open air conditions. Although sticky enough, plant-based adhesives are brittle and vulnerable to environmental conditions. The first use of compound adhesives was discovered in Sibudu, South Africa. Here, 70,000-year-old stone segments that were once inserted in axe hafts were discovered covered with an adhesive composed of plant gum and red ochre (natural iron oxide) as adding ochre to plant gum produces a stronger product and protects the gum from disintegrating under wet conditions. The ability to produce stronger adhesives allowed middle Stone Age humans to attach stone segments to sticks in greater variations, which led to the development of new tools. More recent examples of adhesive use by prehistoric humans have been found at the burial sites of ancient tribes. Archaeologists studying the sites found that approximately 6,000 years ago the tribesmen had buried their dead together with food found in broken clay pots repaired with tree resins. Another investigation by archaeologists uncovered the use of bituminous cements to fasten ivory eyeballs to statues in Babylonian temples dating to approximately 4000 BC. In 2000, a paper revealed the discovery of a 5,200-year-old man nicknamed the "Tyrolean Iceman" or "Ötzi", who was preserved in a glacier near the Austria-Italy border. Several of his belongings were found with him including two arrows with flint arrowheads and a copper hatchet, each with evidence of organic glue used to connect the stone or metal parts to the wooden shafts. The glue was analyzed as pitch, which requires the heating of tar during its production. The retrieval of this tar requires a transformation of birch bark by means of heat, in a process known as pyrolysis. The first references to adhesives in literature appeared in approximately 2000 BC. Further historical records of adhesive use are found from the period spanning 1500–1000 BC. Artifacts from this period include paintings depicting wood gluing operations and a casket made of wood and glue in King Tutankhamun's tomb. Other ancient Egyptian artifacts employ animal glue for bonding or lamination. Such lamination of wood for bows and furniture is thought to have extended their life and was accomplished using casein (milk protein)-based glues. The ancient Egyptians also developed starch-based pastes for the bonding of papyrus to clothing and a plaster of Paris-like material made of calcined gypsum. From AD 1 to 500 the Greeks and Romans made great contributions to the development of adhesives. Wood veneering and marquetry were developed, the production of animal and fish glues refined, and other materials utilized. Egg-based pastes were used to bond gold leaves, and incorporated various natural ingredients such as blood, bone, hide, milk, cheese, vegetables, and grains. The Greeks began the use of slaked lime as mortar while the Romans furthered mortar development by mixing lime with volcanic ash and sand. This material, known as pozzolanic cement, was used in the construction of the Roman Colosseum and Pantheon. The Romans were also the first people known to have used tar and beeswax as caulk and sealant between the wooden planks of their boats and ships. In Central Asia, the rise of the Mongols in approximately AD 1000 can be partially attributed to the good range and power of the bows of Genghis Khan's hordes. These bows were made of a bamboo core, with horn on the belly (facing towards the archer) and sinew on the back, bound together with animal glue. In Europe, glue fell into disuse until the period AD 1500–1700. At this time, world-renowned cabinet and furniture makers such as Thomas Chippendale and Duncan Phyfe began to use adhesives to hold their products together. In 1690, the first commercial glue plant was established in The Netherlands. This plant produced glues from animal hides. In 1750, the first British glue patent was issued for fish glue. The following decades of the next century witnessed the manufacture of casein glues in German and Swiss factories. In 1876, the first U.S. patent (number 183,024) was issued to the Ross brothers for the production of casein glue. The first U.S. postage stamps used starch-based adhesives when issued in 1847. The first US patent (number 61,991) on dextrin (a starch derivative) adhesive was issued in 1867. Natural rubber was first used as material for adhesives starting in 1830, which marked the starting point of the modern adhesive. In 1862, a British patent (number 3288) was issued for the plating of metal with brass by electrodeposition to obtain a stronger bond to rubber. The development of the automobile and the need for rubber shock mounts required stronger and more durable bonds of rubber and metal. This spurred the development of cyclized rubber treated in strong acids. By 1927, this process was used to produce solvent-based thermoplastic rubber cements for metal to rubber bonding. Natural rubber-based sticky adhesives were first used on a backing by Henry Day (US Patent 3,965) in 1845. Later these kinds of adhesives were used in cloth backed surgical and electric tapes. By 1925, the pressure-sensitive tape industry was born. Today, sticky notes, Scotch Tape, and other tapes are examples of pressure-sensitive adhesives (PSA). A key step in the development of synthetic plastics was the introduction of a thermoset plastic known as Bakelite phenolic in 1910. Within two years, phenolic resin was applied to plywood as a coating varnish. In the early 1930s, phenolics gained importance as adhesive resins. The 1920s, 1930s, and 1940s witnessed great advances in the development and production of new plastics and resins due to the First and Second World Wars. These advances greatly improved the development of adhesives by allowing the use of newly developed materials that exhibited a variety of properties. With changing needs and ever evolving technology, the development of new synthetic adhesives continues to the present. However, due to their low cost, natural adhesives are still more commonly used. Types Adhesives are typically organized by the method of adhesion. These are then organized into reactive and non-reactive adhesives, which refers to whether the adhesive chemically reacts in order to harden. Alternatively they can be organized by whether the raw stock is of natural, or synthetic origin, or by their starting physical phase. By reactiveness Non-reactive Drying There are two types of adhesives that harden by drying: solvent-based adhesives and polymer dispersion adhesives, also known as emulsion adhesives. Solvent-based adhesives are a mixture of ingredients (typically polymers) dissolved in a solvent. White glue, contact adhesives and rubber cements are members of the drying adhesive family. As the solvent evaporates, the adhesive hardens. Depending on the chemical composition of the adhesive, they will adhere to different materials to greater or lesser degrees. Polymer dispersion adhesives are milky-white dispersions often based on polyvinyl acetate (PVAc). They are used extensively in the woodworking and packaging industries. They are also used with fabrics and fabric-based components, and in engineered products such as loudspeaker cones. Pressure-sensitive Pressure-sensitive adhesives (PSA) form a bond by the application of light pressure to marry the adhesive with the adherend. They are designed to have a balance between flow and resistance to flow. The bond forms because the adhesive is soft enough to flow (i.e., "wet") to the adherend. The bond has strength because the adhesive is hard enough to resist flow when stress is applied to the bond. Once the adhesive and the adherend are in close proximity, molecular interactions, such as van der Waals forces, become involved in the bond, contributing significantly to its ultimate strength. PSAs are designed for either permanent or removable applications. Examples of permanent applications include safety labels for power equipment, foil tape for HVAC duct work, automotive interior trim assembly, and sound/vibration damping films. Some high performance permanent PSAs exhibit high adhesion values and can support kilograms of weight per square centimeter of contact area, even at elevated temperatures. Permanent PSAs may initially be removable (for example to recover mislabeled goods) and build adhesion to a permanent bond after several hours or days. Removable adhesives are designed to form a temporary bond, and ideally can be removed after months or years without leaving residue on the adherend. Removable adhesives are used in applications such as surface protection films, masking tapes, bookmark and note papers, barcode labels, price marking labels, promotional graphics materials, and for skin contact (wound care dressings, EKG electrodes, athletic tape, analgesic and transdermal drug patches, etc.). Some removable adhesives are designed to repeatedly stick and unstick. They have low adhesion, and generally cannot support much weight. Pressure-sensitive adhesive is used in Post-it notes. Pressure-sensitive adhesives are manufactured with either a liquid carrier or in 100% solid form. Articles are made from liquid PSAs by coating the adhesive and drying off the solvent or water carrier. They may be further heated to initiate a cross-linking reaction and increase molecular weight. 100% solid PSAs may be low viscosity polymers that are coated and then reacted with radiation to increase molecular weight and form the adhesive, or they may be high viscosity materials that are heated to reduce viscosity enough to allow coating, and then cooled to their final form. Major raw material for PSA's are acrylate-based polymers. Contact Contact adhesives are used in strong bonds with high shear-resistance like laminates, such as bonding Formica to a wooden counter, and in footwear, as in attaching outsoles to uppers. Natural rubber and polychloroprene (Neoprene) are commonly used contact adhesives. Both of these elastomers undergo strain crystallization. Contact adhesives must be applied to both surfaces and allowed some time to dry before the two surfaces are pushed together. Some contact adhesives require as long as 24 hours to dry before the surfaces are to be held together. Once the surfaces are pushed together, the bond forms very quickly. It is usually not necessary to apply pressure for a long time, so there is less need for clamps. Hot Hot adhesives, also known as hot melt adhesives, are thermoplastics applied in molten form (in the 65–180 °C range) which solidify on cooling to form strong bonds between a wide range of materials. Ethylene-vinyl acetate-based hot-melts are particularly popular for crafts because of their ease of use and the wide range of common materials they can join. A glue gun (shown at right) is one method of applying hot adhesives. The glue gun melts the solid adhesive, then allows the liquid to pass through its barrel onto the material, where it solidifies. Thermoplastic glue may have been invented around 1940 by Procter & Gamble as a solution to the problem that water-based adhesives, commonly used in packaging at that time, failed in humid climates, causing packages to open. However, water-based adhesives are still of strong interest as they typically do not contain volatile solvents. Reactive Anaerobic Anaerobic adhesives cure when in contact with metal, in the absence of oxygen. They work well in a close-fitting space, as when used as a Thread-locking fluid. Multi-part Multi-component adhesives harden by mixing two or more components which chemically react. This reaction causes polymers to cross-link into acrylates, urethanes, and epoxies . There are several commercial combinations of multi-component adhesives in use in industry. Some of these combinations are: Polyester resin & polyurethane resin Polyols & polyurethane resin Acrylic polymers & polyurethane resins The individual components of a multi-component adhesive are not adhesive by nature. The individual components react with each other after being mixed and show full adhesion only on curing. The multi-component resins can be either solvent-based or solvent-less. The solvents present in the adhesives are a medium for the polyester or the polyurethane resin. The solvent is dried during the curing process. Pre-mixed and frozen adhesives Pre-mixed and frozen adhesives (PMFs) are adhesives that are mixed, deaerated, packaged, and frozen. As it is necessary for PMFs to remain frozen before use, once they are frozen at −80 °C they are shipped with dry ice and are required to be stored at or below −40 °C. PMF adhesives eliminate mixing mistakes by the end user and reduce exposure of curing agents that can contain irritants or toxins. PMFs were introduced commercially in the 1960s and are commonly used in aerospace and defense. One-part One-part adhesives harden via a chemical reaction with an external energy source, such as radiation, heat, and moisture. Ultraviolet (UV) light curing adhesives, also known as light curing materials (LCM), have become popular within the manufacturing sector due to their rapid curing time and strong bond strength. Light curing adhesives can cure in as little as one second and many formulations can bond dissimilar substrates (materials) and withstand harsh temperatures. These qualities make UV curing adhesives essential to the manufacturing of items in many industrial markets such as electronics, telecommunications, medical, aerospace, glass, and optical. Unlike traditional adhesives, UV light curing adhesives not only bond materials together but they can also be used to seal and coat products. They are generally acrylic-based. Heat curing adhesives consist of a pre-made mixture of two or more components. When heat is applied the components react and cross-link. This type of adhesive includes thermoset epoxies, urethanes, and polyimides. Moisture curing adhesives cure when they react with moisture present on the substrate surface or in the air. This type of adhesive includes cyanoacrylates and urethanes. By origin Natural Natural adhesives are made from organic sources such as vegetable starch (dextrin), natural resins, or animals (e.g. the milk protein casein and hide-based animal glues). These are often referred to as bioadhesives. One example is a simple paste made by cooking flour in water. Starch-based adhesives are used in corrugated board and paper sack production, paper tube winding, and wallpaper adhesives. Casein glue is mainly used to adhere glass bottle labels. Animal glues have traditionally been used in bookbinding, wood joining, and many other areas but now are largely replaced by synthetic glues except in specialist applications like the production and repair of stringed instruments. Albumen made from the protein component of blood has been used in the plywood industry. Masonite, a wood hardboard, was originally bonded using natural wood lignin, an organic polymer, though most modern particle boards such as MDF use synthetic thermosetting resins. Synthetic Synthetic adhesives are made out of organic compounds. Many are based on elastomers, thermoplastics, emulsions, and thermosets. Examples of thermosetting adhesives are: epoxy, polyurethane, cyanoacrylate and acrylic polymers. The first commercially produced synthetic adhesive was Karlsons Klister in the 1920s. Application Applicators of different adhesives are designed according to the adhesive being used and the size of the area to which the adhesive will be applied. The adhesive is applied to either one or both of the materials being bonded. The pieces are aligned and pressure is added to aid in adhesion and rid the bond of air bubbles. Common ways of applying an adhesive include brushes, rollers, using films or pellets, spray guns and applicator guns (e.g., caulk gun). All of these can be used manually or automated as part of a machine. Mechanisms of adhesion For an adhesive to be effective it must have three main properties. Firstly, it must be able to wet the base material. Wetting is the ability of a liquid to maintain contact with a solid surface. It must also increase in strength after application, and finally it must be able to transmit load between the two surfaces/substrates being adhered. Adhesion, the attachment between adhesive and substrate may occur either by mechanical means, in which the adhesive works its way into small pores of the substrate, or by one of several chemical mechanisms. The strength of adhesion depends on many factors, including the means by which it occurs. In some cases, an actual chemical bond occurs between adhesive and substrate. In others, electrostatic forces, as in static electricity, hold the substances together. A third mechanism involves the van der Waals forces that develop between molecules. A fourth means involves the moisture-aided diffusion of the glue into the substrate, followed by hardening. Methods to improve adhesion The quality of adhesive bonding depends strongly on the ability of the adhesive to efficiently cover (wet) the substrate area. This happens when the surface energy of the substrate is greater than the surface energy of the adhesive. However, high-strength adhesives have high surface energy. Thus, they bond poorly to low-surface-energy polymers or other materials. To solve this problem, surface treatment can be used to increase the surface energy as a preparation step before adhesive bonding. Importantly, surface preparation provides a reproducible surface allowing consistent bonding results. The commonly used surface activation techniques include plasma activation, flame treatment and wet chemistry priming. Failure There are several factors that could contribute to the failure of two adhered surfaces. Sunlight and heat may weaken the adhesive. Solvents can deteriorate or dissolve adhesive. Physical stresses may also cause the separation of surfaces. When subjected to loading, debonding may occur at different locations in the adhesive joint. The major fracture types are the following: Cohesive fracture Cohesive fracture is obtained if a crack propagates in the bulk polymer which constitutes the adhesive. In this case the surfaces of both adherends after debonding will be covered by fractured adhesive. The crack may propagate in the center of the layer or near an interface. For this last case, the cohesive fracture can be said to be "cohesive near the interface". Adhesive fracture Adhesive fracture (sometimes referred to as interfacial fracture) is when debonding occurs between the adhesive and the adherend. In most cases, the occurrence of adhesive fracture for a given adhesive goes along with smaller fracture toughness. Other types of fracture Other types of fracture include: The mixed type, which occurs if the crack propagates at some spots in a cohesive and in others in an interfacial manner. Mixed fracture surfaces can be characterised by a certain percentage of adhesive and cohesive areas. The alternating crack path type which occurs if the cracks jump from one interface to the other. This type of fracture appears in the presence of tensile pre-stresses in the adhesive layer. Fracture can also occur in the adherend if the adhesive is tougher than the adherend. In this case, the adhesive remains intact and is still bonded to one substrate and remnants of the other. For example, when one removes a price label, the adhesive usually remains on the label and the surface. This is cohesive failure. If, however, a layer of paper remains stuck to the surface, the adhesive has not failed. Another example is when someone tries to pull apart Oreo cookies and all the filling remains on one side; this is an adhesive failure, rather than a cohesive failure. Design of adhesive joints As a general design rule, the material properties of the object need to be greater than the forces anticipated during its use. (i.e. geometry, loads, etc.). The engineering work will consist of having a good model to evaluate the function. For most adhesive joints, this can be achieved using fracture mechanics. Concepts such as the stress concentration factor and the strain energy release rate can be used to predict failure. In such models, the behavior of the adhesive layer itself is neglected and only the adherents are considered. Failure will also very much depend on the opening mode of the joint. Mode I is an opening or tensile mode where the loadings are normal to the crack. Mode II is a sliding or in-plane shear mode where the crack surfaces slide over one another in direction perpendicular to the leading edge of the crack. This is typically the mode for which the adhesive exhibits the highest resistance to fracture. Mode III is a tearing or antiplane shear mode. As the loads are usually fixed, an acceptable design will result from combination of a material selection procedure and geometry modifications, if possible. In adhesively bonded structures, the global geometry and loads are fixed by structural considerations and the design procedure focuses on the material properties of the adhesive and on local changes on the geometry. Increasing the joint resistance is usually obtained by designing its geometry so that: The bonded zone is large It is mainly loaded in mode II Stable crack propagation will follow the appearance of a local failure. Shelf life Some glues and adhesives have a limited shelf life. Shelf life is dependent on multiple factors, the foremost of which being temperature. Adhesives may lose their effectiveness at high temperatures, as well as become increasingly stiff. Other factors affecting shelf life include exposure to oxygen or water vapor.

Sir Philip Anthony Hopkins (born 31 December 1937) is a Welsh actor, director, and producer. One of Britain's most recognisable and prolific actors, he is known for his performances on the screen and stage. Hopkins has received numerous accolades, including two Academy Awards, four BAFTA Awards, two Primetime Emmy Awards, and a Laurence Olivier Award. He has also received the Cecil B. DeMille Award in 2005 and the BAFTA Fellowship for lifetime achievement in 2008. He was knighted by Queen Elizabeth II for his services to drama in 1993. After graduating from the Royal Welsh College of Music & Drama in 1957, Hopkins trained at the Royal Academy of Dramatic Art in London. He was then spotted by Laurence Olivier, who invited him to join the Royal National Theatre in 1965. Productions at the National included King Lear (his favourite Shakespeare play), Coriolanus, Macbeth, and Antony and Cleopatra. In 1985, he received great acclaim and a Laurence Olivier Award for his performance in the David Hare play Pravda. His last stage play was a West End production of M. Butterfly in 1989. Hopkins early film roles include The Lion in Winter (1968), A Bridge Too Far (1977), and The Elephant Man (1980). He won two Academy Awards for Best Actor for playing Hannibal Lecter in The Silence of the Lambs (1991) and an octogenarian with dementia in The Father (2020), becoming the oldest Best Actor Oscar winner for the latter. His other Oscar-nominated films include The Remains of the Day (1993), Nixon (1995), Amistad (1997), and The Two Popes (2019). Other notable films include 84 Charing Cross Road (1987), Howards End (1992), Bram Stoker's Dracula (1992), Shadowlands (1993), Legends of the Fall (1994), The Mask of Zorro (1998), and the Marvel Cinematic Universe's Thor franchise (2011–2017). For his work on television, Hopkins received a British Academy Television Award for Best Actor for his performance in War and Peace (1972). He won two Primetime Emmy Awards for Outstanding Actor in a Drama Series for The Lindbergh Kidnapping Case (1976) and The Bunker (1981). Other notable projects include the BBC film The Dresser (2015), PBS's King Lear (2018), and the HBO series Westworld (2016–2018). Early life and education Philip Anthony Hopkins was born in the Margam district of Port Talbot on 31 December 1937, the son of Annie Muriel (née Yeates) and baker Richard Arthur Hopkins. One of his grandfathers was from Wiltshire, England. He stated his father's working-class values have always underscored his life, "Whenever I get a feeling that I may be special or different, I think of my father and I remember his hands – his hardened, broken hands." His school days were unproductive; he would rather immerse himself in art, such as painting and drawing, or playing the piano than attend to his studies. In 1949, to instil discipline, his parents insisted he attend Jones' West Monmouth Boys' School in Pontypool. He remained there for five terms and was then educated at Cowbridge Grammar School in the Vale of Glamorgan. In an interview in 2002, he stated, "I was a poor learner, which left me open to ridicule and gave me an inferiority complex. I grew up absolutely convinced I was stupid." Hopkins was inspired by fellow Welsh actor Richard Burton, whom he met at the age of 15. He later called Burton "very gracious, very nice" but elaborated, "I don't know where everyone gets the idea we were good friends. I suppose it's because we are both Welsh and grew up near the same town. For the record, I didn't really know him at all." He enrolled at the Royal Welsh College of Music & Drama in Cardiff, from which he graduated in 1957. He next met Burton in 1975 as Burton prepared to take over Hopkins's role as the psychiatrist in Peter Shaffer's Equus, with Hopkins stating, "He was a phenomenal actor. So was Peter O'Toole – they were wonderful, larger-than-life characters." After two years of his national service between 1958 and 1960, which he served in the British Army, Hopkins moved to London to study at the Royal Academy of Dramatic Art. Acting career 1960–1979: National Theatre and film debut Hopkins made his first professional stage appearance in the Palace Theatre, Swansea, in 1960 with Swansea Little Theatre's production of Have a Cigarette. In 1965, after several years in repertory, he was spotted by Laurence Olivier, who invited him to join the Royal National Theatre in London. Hopkins became Olivier's understudy, and filled in when Olivier was struck with appendicitis during a 1967 production of August Strindberg's The Dance of Death. Olivier later noted in his memoir, Confessions of an Actor, that, "A new young actor in the company of exceptional promise named Anthony Hopkins was understudying me and walked away with the part of Edgar like a cat with a mouse between its teeth." Up until that night, Hopkins was always nervous prior to going on stage. This has since changed, and Hopkins quoted his mentor as saying: "He [Olivier] said: 'Remember: nerves is [sic] vanity – you're wondering what people think of you; to hell with them, just jump off the edge'. It was great advice." He made his small-screen debut in a 1967 BBC broadcast of A Flea in Her Ear. His first starring role in a film came in 1964 in Changes, a short directed by Drewe Henley, written and produced by James Scott and co-starring Jacqueline Pearce. In 1968, Hopkins got his break in The Lion in Winter playing Richard the Lionheart, a performance which saw him nominated for the BAFTA Award for Best Actor in a Supporting Role. Hopkins portrayed Charles Dickens in the BBC television film The Great Inimitable Mr. Dickens in 1970, and Pierre Bezukhov in the BBC's mini series War and Peace (1972), receiving the British Academy Television Award for Best Actor for his performance in the latter. Making a name for himself as a screen actor, he appeared in Frank Pierson's neo-noir action thriller The Looking Glass War (1970), and Étienne Périer's When Eight Bells Toll (1971). The first of five collaborations with director Richard Attenborough, in 1972 Hopkins starred as British politician David Lloyd George in Young Winston, and in 1977 he played British Army officer John Frost in Attenborough's World War II-set film A Bridge Too Far. In 1973 he again portrayed David Lloyd George in the BBC miniseries The Edwardians which aired in the US in 1974 on Masterpiece Theatre. Hopkins starred in a film adaptation of the Henrik Ibsen play A Doll's House (1973) alongside Claire Bloom, Ralph Richardson, Denholm Elliott, and Edith Evans. He then appeared in the comedy The Girl from Petrovka (1974) with Goldie Hawn and Hal Holbrook and also starred in the Richard Lester suspense film Juggernaut opposite Richard Harris and Omar Sharif. In October 1974, Hopkins played the psychologist Dysart in the original Broadway production of Sir Peter Shaffer's play Equus, starring opposite Peter Firth. For this performance, he received the Drama Desk Award for Outstanding Actor in a Play for the 1974–75 season. In 1978 he starred in the sequel to National Velvet (1944), entitled International Velvet with Tatum O'Neal, Christopher Plummer, which was directed by Bryan Forbes. In 1978 he also starred in Attenborough's psychological horror film Magic about a demonic ventriloquist's puppet with Gene Siskel adding it as one of the best films of the year. In 1979, Hopkins appeared as Prospero in a production of The Tempest held at the Mark Taper Forum in Los Angeles. 1980–1989: Rise to prominence In 1980, he starred in David Lynch's The Elephant Man as the English doctor Sir Frederick Treves, who attends to Joseph Merrick (portrayed by John Hurt), a severely deformed man in 19th century London. The film received critical praise and attention from critics and received eight Academy Award nominations including for Best Picture. That year he also starred opposite Shirley MacLaine in A Change of Seasons and famously didn't get along with MacLaine, adding "she was the most obnoxious actress I have ever worked with." The film was an immense box office and critical failure. In 1981, he starred in the CBS television film The Bunker portraying Adolf Hitler during weeks in and around his underground bunker in Berlin before and during the Battle of Berlin. John O'Connor praised Hopkins in his New York Times review: "The portrait becomes all the more riveting through an extraordinarily powerful performance from Anthony Hopkins. His Hitler is mad, often contemptible, but always understandable. Part of the problem, perhaps, is that the monster becomes a little too understandable. He is not made sympathetic, exactly, but he is given decidedly pathetic dimensions, making him just that much more acceptable as a dramatic and historical character." For his performance he received a Primetime Emmy Award for Outstanding Lead Actor in a Limited Series or Movie. That same year he starred as Paul the Apostle opposite Robert Foxworth as Saint Peter in the biblical drama and miniseries Peter and Paul (1981). In 1983, Hopkins also became a company member of The Mirror Theater Ltd's Repertory Company. In 1984, he portrayed Deeley in Harold Pinter's play Old Times at the Roundabout Theatre in New York. In 1984, he starred opposite Mel Gibson in The Bounty as William Bligh, captain of the Royal Navy ship , in a more accurate retelling of the mutiny on the Bounty. The following year he starred as Quasimodo in the CBS television film The Hunchback of Notre Dame (1982). The film also starred Derek Jacobi, David Suchet, Tim Pigott-Smith, Nigel Hawthorne, and John Gielgud. He also starred in Strangers and Brothers (1984), Arch of Triumph (1984), Guilty Conscience (1985), Mussolini and I (1985), and The Tenth Man (1988). In 1985, Hopkins starred opposite Colin Firth in the Arthur Schnitzler play The Lonely Road at The Old Vic in London. That same year, he featured as Lambert Le Roux in the National Theatre production of Pravda in Sir David Hare and Howard Brenton's satirical play on the British newspaper industry in the Thatcher era. Receiving acclaim for his performance, Hopkins won the Laurence Olivier Award for Outstanding Achievement. Frank Rich in his New York Times review wrote, "Mr. Hopkins creates a memorable image of a perversely brilliant modern-day barbarian." In 1986, he starred in David Hare's production of King Lear, Hopkins's favourite Shakespeare play, at the National Theatre. The next year, he starred as Antony in the National Theatre production of Antony and Cleopatra opposite Judi Dench, and in 1989, Hopkins made his last appearance on stage in a West End production of M. Butterfly. "It was a torment", he claimed in a later interview. Of a matinee where nobody laughed, there was, he said "not a titter". When the lights came up, the cast realised the entire audience was Japanese. "Oh God," he recalled, "You'd go to your dressing room and someone would pop their head round the door and say, 'Coffee? Tea?' And I'd think, 'An open razor, please.'" In 1989 he starred as Abel Magwitch in the miniseries Great Expectations which was broadcast on ITV in the UK and The Disney Channel in the US. The adaptation of the Dickens' novel also starred Jean Simmons and John Rhys-Davies. He received his fourth Primetime Emmy Award nomination, this time for Outstanding Supporting Actor in a Limited Series or Movie. 1990–1998: Stardom and acclaim Hopkins won acclaim among critics and audiences as the cannibalistic serial killer Hannibal Lecter in The Silence of the Lambs, for which he won the Academy Award for Best Actor in 1991, with Jodie Foster as Clarice Starling, who also won for Best Actress. The film won Best Picture, Best Director and Best Adapted Screenplay, and Hopkins also picked up his first BAFTA for Best Actor. Hopkins reprised his role as Lecter twice; in Ridley Scott's Hannibal (2001), and Red Dragon (2002). His original portrayal of the character in The Silence of the Lambs has been labelled by the AFI as the number-one film villain. Director Jonathan Demme wanted a British actor for the role, with Jodie Foster stating, "Lecter is a manipulator and has a way of using language to keep people at bay. You wanted to see that Shakespearean monster." At the time he was offered the role, Hopkins was making a return to the London stage, performing in M. Butterfly. He had come back to Britain after living for a number of years in Hollywood, having all but given up on a career there, saying, "Well that part of my life's over; it's a chapter closed. I suppose I'll just have to settle for being a respectable actor poncing around the West End and doing respectable BBC work for the rest of my life." Hopkins reprised the role, returning to the iconic villain in adaptations of the first three of the Lecter novels by Thomas Harris. The author was reportedly pleased with Hopkins's portrayal of his antagonist. However, Hopkins stated that Red Dragon (2002) would feature his final performance as the character and that he would not reprise even a narrative role in the latest addition to the series, Hannibal Rising (2007). The following year, After winning the Oscar for Silence of the Lambs, Hopkins was featured in Mark Joffe's film Spotswood and the science fiction film Freejack and also played supporting roles as Charlie Chaplin's biographer in Richard Attenborough's biographical drama Chaplin (1992) and Professor Van Helsing in Francis Ford Coppola's horror adaptation Bram Stoker's Dracula (1992). In 1992, Hopkins starred in Merchant-Ivory's period film based on the E. M. Forster novel Howards End. Hopkins acted alongside Emma Thompson and Helena Bonham Carter where he played the cold businessman Henry Wilcox. The film received enormous critical acclaim, with critic Leonard Maltin calling it "extraordinarily good on every level." The following year, Hopkins reunited with Merchant-Ivory and Emma Thompson in The Remains of the Day (1993), a film set in 1950s post-war Britain based on the novel by Kazuo Ishiguro. David Hunter of The Hollywood Reporter praised Hopkins' performance describing it as "colossal" and a "tour de force". The film was ranked by the British Film Institute as the 64th greatest British film of the 20th century. Starring as the butler Stevens, Hopkins named it among his favourite films. He was nominated for an Academy Award for Best Actor for his performance and received the BAFTA Award for Best Actor. Hopkins portrayed Oxford academic C. S. Lewis in the 1993 British biographical film Shadowlands, for which he was nominated for a BAFTA Award for Best Actor. Also that year he acted opposite Isabella Rossellini in the drama The Innocent (1993) which was adapted from the Ian McEwan novel of the same name. During this period, Hopkins had the chance to work with Bart the Bear in two films: Legends of the Fall (1994) and The Edge (1997). According to trainer, Lynn Seus, "Tony Hopkins was absolutely brilliant with Bart...He acknowledged and respected him like a fellow actor. He would spend hours just looking at Bart and admiring him. He did so many of his own scenes with Bart." Hopkins was Britain's highest paid performer in 1998, starring in The Mask of Zorro and Meet Joe Black, and also agreed to reprise his role as Dr Hannibal Lecter for a fee of £15 million. 2000–2014: Established actor In 2000, Hopkins narrated Ron Howard's live action remake of How the Grinch Stole Christmas. He then reprised the role of Hannibal Lecter in The Silence of the Lambs (1991) sequel simply entitled Hannibal (2001). Director Ridley Scott and actress Julianne Moore replaced Jonathan Demme and Jodie Foster who declined to participate in the sequel. Hopkins, who previously starred with Moore in Surviving Picasso (1996), agreed to do the role approving of the script. In the book, Lecter uses bandages to disguise himself as a plastic surgery patient. This was left out of the film because Scott and Hopkins agreed to leave the face alone. Hopkins said: "It's as if he's making a statement—'catch me if you can'. With his big hat, he's so obvious that nobody thinks he's Hannibal Lecter. I've always thought he's a very elegant man, a Renaissance man.": In the film, Lecter is first seen in Florence "as the classical Lecter, lecturing and being smooth", according to Hopkins. When the film moves to the U.S., Hopkins changed his appearance by building up muscle and cropping his hair short "to make him like a mercenary, that he would be so fit and so strong that he could just snap somebody in two if they got ... in his way". The film broke international box office records receiving $351 million. but received mixed reviews from critics. Hopkins starred in the third film in the series Red Dragon (2002) alongside Ralph Fiennes, Edward Norton, Harvey Keitel, Emily Watson, and Philip Seymour Hoffman. The film received favourable reviews and was a box office hit. In 2003, Hopkins received a star on the Hollywood Walk of Fame. Hopkins stated that his role as Burt Munro, whom he portrayed in his 2005 film The World's Fastest Indian, was his favourite. He also asserted that Munro was the easiest role that he had played because both men have a similar outlook on life. In 2006, Hopkins was the recipient of the Golden Globe Cecil B. DeMille Award for lifetime achievement. In 2008, he received the BAFTA Academy Fellowship Award, the highest award the British Film Academy can bestow. In a 2003 poll conducted by Channel 4 Hopkins was ranked seventh on their list of the 100 Greatest Movie Stars. On 24 February 2010, it was announced that Hopkins had been cast in The Rite, which was released on 28 January 2011. He played a priest who is "an expert in exorcisms and whose methods are not necessarily traditional". Hopkins, an agnostic who is quoted as saying "I don't know what I believe, myself personally", reportedly wrote a line—"Some days I don't know if I believe in God or Santa Claus or Tinkerbell"—into his character to identify with it. In 2011, Hopkins has said, "what I enjoy is uncertainty. ... I don't know. You don't know." On 21 September 2011, Peter R. de Vries cast Hopkins in the role of the Heineken owner Freddy Heineken, in the film about his kidnapping. Kidnapping Freddy Heineken, was released in 2015. Hopkins portrayed Odin, the Allfather or "king" of Asgard, in the 2011 film adaptation of Marvel Comics' Thor and would go on to reprise his role as Odin in Thor: The Dark World in 2013, and again in 2017's Thor: Ragnarok. Hopkins portrayed Alfred Hitchcock in Sacha Gervasi's biopic Hitchcock alongside Helen Mirren who played Hitchcock's wife, Alma Reville. The film focuses on the film of Psycho and that which followed. He starred in the comedy action film Red 2 (2013) as the main antagonist Edward Bailey. In 2014, he portrayed Methuselah in Darren Aronofsky's Noah. Hopkins played Autobot ally Sir Edmund Burton in Transformers: The Last Knight, which was released in June 2017. 2015–present: Career resurgence In October 2015, Hopkins appeared as Sir in a BBC Two production of Ronald Harwood's The Dresser, alongside Ian McKellen, Edward Fox and Emily Watson. The Dresser is set in a London theatre during the Blitz, where an aging actor-manager, Sir, prepares for his starring role in King Lear with the help of his devoted dresser, Norman. Hopkins described his role as Sir as "the highlight of my life. It was a chance to work with the actors I had run away from. To play another actor is fun because you know the ins and outs of their thinking – especially with someone like Sir, who is a diabolically insecure, egotistical man." He spoke again on the impact the role had on him in 2018, "When I was at the Royal National Theatre all those years ago, I knew I had something in me, but I didn't have the discipline. I had a Welsh temperament and didn't have that 'fitting in' mechanism. I would fight, I would rebel. I thought, 'Well, I don't belong here.' And for almost 50 years afterwards, I felt that edge of, 'I don't belong anywhere, I'm a loner.' But in The Dresser, when Ian [McKellen] responded, it was wonderful. We got on so well and I suddenly felt at home, as though that lack of belonging was all in my imagination, all in my vanity". Beginning in October 2016, Hopkins starred as Robert Ford in the HBO sci-fi series Westworld where he received a Primetime Emmy Award nomination for his performance. Hopkins starred as Lear in the 2018 television film King Lear acting alongside Emma Thompson, Florence Pugh, and Jim Broadbent which was broadcast on BBC Two on 28 May 2018. Hopkins received a Screen Actors Guild Award nomination for his performance. Vulture stated the film "capture[d] the heart of the classic Shakespeare tragedy" and described Hopkins' performance as "devastating". In 2019, Hopkins portrayed Pope Benedict XVI opposite Jonathan Pryce as Pope Francis in Fernando Meirelles's The Two Popes. He stated, "The great treasure was working with – apart from [director] Meirelles – Pryce. We're both from Wales. He's from the north, and I'm from the south". The film is set in the Vatican City in the aftermath of the Vatican leaks scandal and follows Pope Benedict XVI as he attempts to convince Cardinal Jorge Mario Bergoglio to reconsider his decision to resign as an archbishop as he confides his own intentions to abdicate the papacy. In August 2019, the film premiered at the Telluride Film Festival to critical acclaim. The film started streaming on 20 December 2019, by Netflix. The performances of Pryce and Hopkins, as well as McCarten's screenplay, received high praise from critics, and all three men received nominations for their work at the Academy Awards, Golden Globes and British Academy Film Awards. In 2020, Hopkins played a man struggling with Alzheimer's disease in The Father. The film premiered at the Sundance Film Festival where it received critical acclaim, with many critics praising Hopkins's performance and calling him a standout and Oscar frontrunner. The film also stars Olivia Colman as his daughter. It is based on a Tony Award nominated play Le Père by Florian Zeller, who also directed the film. The Father was released on 18 December 2020 by Sony Pictures Classics. In a Q&A at the Telluride Film Festival Hopkins praised both Colman and Zeller saying comparing the working experience saying it "might've been the highlight of my life". Hopkins mentioned how lucky he's been over the past five years working with Ian McKellen in The Dresser, Emma Thompson in King Lear, and Jonathan Pryce in The Two Popes. Hopkins won the BAFTA Award for Best Actor in a Leading Role for his performance in The Father, making it his fourth BAFTA and his third for Best Actor. He also won a second Academy Award for Best Actor for his role, becoming the oldest person to win an acting Oscar. Hopkins did not attend the Oscars ceremony, but accepted the award in a video posted on social media, from Wales, the following day, saying: "Here I am in my homeland in Wales. And at 83 years of age, I did not expect to get this award. I really didn't and am very grateful to the Academy and thank you." He also paid tribute to fellow nominee Chadwick Boseman, who had died the previous year. In 2022 he acted in James Gray's semi-autobiographical coming of age drama Armageddon Time (2023). Hopkins starred alongside Jeremy Strong and Anne Hathaway. Hopkins received positive reviews for his turn as a kindly elderly grandfather. A.O. Scott of The New York Times wrote, "Hopkins finds the essential grit hiding underneath the twinkle". That same year he reunited with Florian Zeller, acting in The Son (2022) alongside Hugh Jackman. Hopkins is set to star as Nicholas Winton in the drama film One Life and Sigmund Freud in Freud's Last Session. Hopkins was cast in the upcoming Netflix science fiction film Rebel Moon directed by Zack Snyder. Composing Single In a 2012 interview, Hopkins stated, "I've been composing music all my life and if I'd been clever enough at school I would like to have gone to music college. As it was I had to settle for being an actor." In 1986, he released a single called "Distant Star", which peaked at No. 75 in the UK Singles Chart. In 2007, he announced he would retire temporarily from the screen to tour around the world. Hopkins has also written music for the concert hall, in collaboration with Stephen Barton as orchestrator. These compositions include The Masque of Time, given its world premiere with the Dallas Symphony Orchestra in October 2008, and Schizoid Salsa. Albums On 31 October 2011, André Rieu released an album including a waltz which Hopkins had composed in 1964, at the age of 26. Hopkins had never heard his composition, "And the Waltz Goes On", before it was premiered by Rieu's orchestra in Vienna; Rieu's album was given the same name as Hopkins's piece. In January 2012, Hopkins released an album of classical music, entitled Composer, performed by the City of Birmingham Symphony Orchestra, and released on CD via the UK radio station Classic FM. The album consists of nine of his original works and film scores, with one of the pieces titled "Margam" in tribute to his home town near Port Talbot in Wales. Directing In 1990, Hopkins directed a film about his Welsh compatriot, poet Dylan Thomas, titled Dylan Thomas: Return Journey, which was his directing debut for the screen. In the same year, as part of the restoration process for the Stanley Kubrick film Spartacus, Hopkins was approached to re-record lines from a scene that was being added back to the film; this scene featured Laurence Olivier and Tony Curtis, with Hopkins recommended by Olivier's widow, Joan Plowright to perform her late husband's part thanks to his talent for mimicry. In 1995, he directed August, an adaptation of Chekhov's Uncle Vanya set in Wales. His first screenplay, an experimental drama called Slipstream, which he also directed and scored, premiered at the Sundance Film Festival in 2007. In 1997, Hopkins narrated the BBC natural documentary series, Killing for a Living, which showed predatory behaviour in nature. He narrated episode 1 through 3 before being replaced by John Shrapnel. Reception and acting style Hopkins is renowned for his preparation for roles. He indicated in interviews that once he has committed to a project, he will go over his lines as many times as is needed (sometimes upwards of 200) until the lines sound natural to him, so that he can "do it without thinking". This leads to an almost casual style of delivery that belies the amount of groundwork done beforehand. While it can allow for some careful improvisation, it has also brought him into conflict with the occasional director who departs from the script or demands what the actor views as an excessive number of takes. Hopkins has stated that after he is finished with a scene, he simply discards the lines, not remembering them later on. This is unlike others who usually remember their lines from a film, even years later. In the mid-1970s, he started a collaboration with Richard Attenborough who called him "the greatest actor of his generation". Attenborough, who directed Hopkins on five occasions, found himself going to great lengths during the filming of Shadowlands (1993) to accommodate the differing approaches of his two stars (Hopkins and Debra Winger), who shared many scenes. Whereas Hopkins preferred the spontaneity of a fresh take and liked to keep rehearsals to a minimum, Winger rehearsed continuously. To allow for this, Attenborough stood in for Hopkins during Winger's rehearsals, only bringing him in for the last one before a take. The director praised Hopkins for "this extraordinary ability to make you believe when you hear him that it is the very first time he has ever said that line. It's an incredible gift." Renowned for his ability to remember lines, Hopkins keeps his memory supple by learning things by heart such as poetry and Shakespeare. In Steven Spielberg's Amistad (1997), Hopkins astounded the crew with his memorisation of a seven-page courtroom speech, delivering it in one go. An overawed Spielberg could not bring himself to call Hopkins "Tony" and insisted on addressing him as Sir Anthony throughout the shoot. In a 2016 interview with the Radio Times, Hopkins spoke of his ability to frighten people since he was a boy growing up in Port Talbot, Wales. "I don't know why but I've always known what scares people. When I was a kid I'd tell the girls around the street the story about Dracula and I'd go 'th-th-th' (the sucking noise which he reproduced in The Silence of the Lambs). As a result, they'd run away screaming." He recalled going through the script of Silence of the Lambs for the first time with fellow cast members. "I didn't know what they were going to make of it but I'd prepared it—my first line to Jodie Foster was: 'Good morning. You're one of Jack Crawford's aren't you?' Everyone froze. There was a silence. Then one of the producers said, 'Holy crap, don't change a thing'." On Hopkins's approach to playing villains, Miranda Sawyer in The Guardian writes, "When he portrays deliberately scary people, he plays them quietly, emphasising their sinister control." Hopkins is a well-known mimic, adept at turning his native Welsh accent into whatever is required by a character. In the 1991 restoration of Spartacus, he recreated the voice of his late mentor Laurence Olivier in a scene for which the soundtrack had been lost. His interview on the 1998 relaunch edition of the British television talk show Parkinson featured an impersonation of comedian Tommy Cooper. Hopkins has said acting "like a submarine" has helped him to deliver credible performances in his thrillers. He said, "It's very difficult for an actor to avoid, you want to show a bit. But I think the less one shows the better." Acting credits Awards, honours and legacy Hopkins was appointed a CBE in 1987 and was knighted by Queen Elizabeth II for "services to the arts" at Buckingham Palace in 1993. In 1988, he was awarded an honorary D.Litt. degree and in 1992 received an honorary fellowship from the University of Wales, Lampeter. He was made a freeman of his home town, Port Talbot, in 1996. Hopkins has also been honored with various lifetime achievement awards for his work in film and television. In 2006, Gwyneth Paltrow presented him with the Golden Globe Cecil B. DeMille Award. In 2008, Richard Attenborough presented Hopkins with the BAFTA Fellowship for lifetime achievement from the British Academy of Film and Television Arts. Hopkins has also received a star on the Hollywood Walk of Fame in 2003. In 2021, Hopkins won the Oscar for the Best Actor for The Father. He became the oldest nominee and winner of the award. Personal life Hopkins resides in Malibu, California. He had moved to the United States once before, during the late 1970s, to pursue his film career, but returned to London in the late 1980s. However, he decided to return to the US following his 1990s success. Retaining his British citizenship, he became a naturalised American citizen on 12 April 2000, with Hopkins stating: "I have dual citizenship; it just so happens I live in America". Hopkins has been married three times. He was married to actress Petronella Barker from 1966 to 1972, Jennifer Lynton from 1973 to 2002, and Stella Arroyave since 2003. Hopkins met Arroyave, a Colombian-born antiques dealer in the early 2000s, and he credits her with helping him overcome his feelings of depression at the time. On Christmas Eve 2013, he celebrated his 10th wedding anniversary by having a blessing at a private service at St Davids Cathedral in St Davids. He has a daughter from his first marriage. The two are estranged; when asked if he had any grandchildren, he said, "I don't have any idea. People break up. Families split and, you know, 'Get on with your life.' People make choices. I don't care one way or the other." Hopkins previously suffered from alcoholism; he has stayed sober since he stopped drinking just after Christmas 1975. He said, "I made that quantum leap when I asked for help. I just found something and a woman talked to me and she said, just trust in God. And I said, well, why not?" When asked, "Did you literally pray?" Hopkins responded: "No, I didn't. I think because I asked for help, which is a form of prayer." In January 2020, when asked if he was still agnostic, he responded, "Agnosticism is a bit strange. An agnostic doubts and atheism denies. I'm not a holy Joe; I'm just an old sinner like everyone else. I do believe more than ever now that there is a vast area of our own lives that we know nothing about. As I get older, I can cry at the drop of a hat because the wonderful, terrible passion of life is so short. I have to believe there's something bigger than me. I'm just a microbe. That, for me, is the biggest feeling of relief – acknowledging that I am really nothing. I'm compelled to say, whoever's running the show, thank you very much." Hopkins quit smoking using the Allen Carr method. In 2008, he embarked on a weight loss programme, and by 2010, he had lost 5st 10 lb (80 lb or 36 kg). In January 2017, in an interview with The Desert Sun, Hopkins said that he had been diagnosed with Asperger syndrome three years earlier, but that he was "high end". In 2020, he said that "it's a great gift, actually". He has a pet cat named Niblo, which he adopted in Budapest. Hopkins eschews meat and prefers a pescatarian diet. He is a fan of the BBC sitcom Only Fools and Horses, and once remarked in an interview how he would love to appear in the series. Writer John Sullivan saw the interview, and with Hopkins in mind created the character Danny Driscoll, a local villain. However, filming of the new series coincided with the filming of The Silence of the Lambs, making Hopkins unavailable. The role instead went to Roy Marsden. Philanthropy Hopkins has offered his support to various charities and appeals, notably becoming President of the National Trust's Snowdonia Appeal, raising funds for the preservation of Snowdonia National Park in north Wales. In 1998 he donated £1 million towards the £3 million needed to aid the Trust's efforts in purchasing parts of Snowdon. Prior to the campaign, Hopkins wrote Anthony Hopkins' Snowdonia, which was published in 1995. Due to his contributions to Snowdonia, in addition to his film career, in 2004 Hopkins was named among the 100 Welsh Heroes in a Welsh poll. Hopkins has been a patron of the YMCA centre in his home town of Port Talbot, South Wales, for more than 20 years, having first joined the YMCA in the 1950s. He supports other various philanthropic groups. He was a Guest of Honour at a Gala Fundraiser for Women in Recovery, Inc., a Venice, California-based non-profit organisation offering rehabilitation assistance to women in recovery from substance abuse. He is also a volunteer teacher at the Ruskin School of Acting in Santa Monica, California. Hopkins served as the Honorary Patron of The New Heritage Theatre Company in Boise, Idaho from 1997 to 2007, participating in fundraising and marketing efforts for the repertory theatre. Hopkins contributed toward the refurbishment of a £2.3 million wing at his alma mater, the Royal Welsh College of Music & Drama in Cardiff, named the Anthony Hopkins Centre. It opened in 1999. Hopkins is a prominent member of the environmental protection group Greenpeace and as of early 2008 featured in a television advertisement campaign, voicing concerns about whaling in Japan. He has also been a patron of RAPt (Rehabilitation for Addicted Prisoners Trust) since its early days and in 1992 helped open their first intensive drug and alcohol rehabilitation unit at Downview (HM Prison), a women's prison in Surrey, England. Hopkins is an admirer of the late Welsh comedian Tommy Cooper. On 23 February 2008, as patron of the Tommy Cooper Society, he unveiled a commemorative statue in the entertainer's home town of Caerphilly. For the ceremony, he donned Cooper's trademark fez and performed a comic routine.

Advanced Micro Devices, Inc., commonly abbreviated as AMD, is an American multinational semiconductor company based in Santa Clara, California, that develops computer processors and related technologies for business and consumer markets. The company was founded in 1969 by Jerry Sanders and a group of other technology professionals. AMD's early products were primarily memory chips and other components for computers. The company later expanded into the microprocessor market, competing with Intel, its main rival in the industry. In the early 2000s, AMD experienced significant growth and success, thanks in part to its strong position in the PC market and the success of its Athlon and Opteron processors. However, the company faced challenges in the late 2000s and early 2010s, as it struggled to keep up with Intel in the race to produce faster and more powerful processors. In the late 2010s, AMD regained some of its market share thanks to the success of its Ryzen processors which are now widely regarded as superior to Intel products in business applications including cloud applications. AMD's processors are used in a wide range of computing devices, including personal computers, servers, laptops, and gaming consoles. While it initially manufactured its own processors, the company later outsourced its manufacturing, a practice known as going fabless, after GlobalFoundries was spun off in 2009. AMD's main products include microprocessors, motherboard chipsets, embedded processors, graphics processors, and FPGAs for servers, workstations, personal computers, and embedded system applications. The company has also expanded into new markets, such as the data center and gaming markets, and has announced plans to enter the high-performance computing market. History First twelve years Advanced Micro Devices was formally incorporated by Jerry Sanders, along with seven of his colleagues from Fairchild Semiconductor, on May 1, 1969. Sanders, an electrical engineer who was the director of marketing at Fairchild, had, like many Fairchild executives, grown frustrated with the increasing lack of support, opportunity, and flexibility within the company. He later decided to leave to start his own semiconductor company, following the footsteps of Robert Noyce (developer of the first silicon integrated circuit at Fairchild in 1959) and Gordon Moore, who together founded the semiconductor company Intel in July 1968. In September 1969, AMD moved from its temporary location in Santa Clara to Sunnyvale, California. To immediately secure a customer base, AMD initially became a second source supplier of microchips designed by Fairchild and National Semiconductor. AMD first focused on producing logic chips. The company guaranteed quality control to United States Military Standard, an advantage in the early computer industry since unreliability in microchips was a distinct problem that customers – including computer manufacturers, the telecommunications industry, and instrument manufacturers – wanted to avoid. In November 1969, the company manufactured its first product: the Am9300, a 4-bit MSI shift register, which began selling in 1970. Also in 1970, AMD produced its first proprietary product, the Am2501 logic counter, which was highly successful. Its bestselling product in 1971 was the Am2505, the fastest multiplier available. In 1971, AMD entered the RAM chip market, beginning with the Am3101, a 64-bit bipolar RAM. That year AMD also greatly increased the sales volume of its linear integrated circuits, and by year-end the company's total annual sales reached US$4.6 million. AMD went public in September 1972. The company was a second source for Intel MOS/LSI circuits by 1973, with products such as Am14/1506 and Am14/1507, dual 100-bit dynamic shift registers. By 1975, AMD was producing 212 products – of which 49 were proprietary, including the Am9102 (a static N-channel 1024-bit RAM) and three low-power Schottky MSI circuits: Am25LS07, Am25LS08, and Am25LS09. Intel had created the first microprocessor, its 4-bit 4004, in 1971. By 1975, AMD entered the microprocessor market with the Am9080, a reverse-engineered clone of the Intel 8080, and the Am2900 bit-slice microprocessor family. When Intel began installing microcode in its microprocessors in 1976, it entered into a cross-licensing agreement with AMD, which was granted a copyright license to the microcode in its microprocessors and peripherals, effective October 1976. In 1977, AMD entered into a joint venture with Siemens, a German engineering conglomerate wishing to enhance its technology expertise and enter the American market. Siemens purchased 20% of AMD's stock, giving the company an infusion of cash to increase its product lines. The two companies also jointly established Advanced Micro Computers (AMC), located in Silicon Valley and in Germany, allowing AMD to enter the microcomputer development and manufacturing field, in particular based on AMD's second-source Zilog Z8000 microprocessors. When the two companies' vision for Advanced Micro Computers diverged, AMD bought out Siemens' stake in the American division in 1979. AMD closed Advanced Micro Computers in late 1981 after switching focus to manufacturing second-source Intel x86 microprocessors. Total sales in fiscal year 1978 topped $100 million, and in 1979, AMD debuted on the New York Stock Exchange. In 1979, production also began on AMD's new semiconductor fabrication plant in Austin, Texas; the company already had overseas assembly facilities in Penang and Manila, and began construction on a fabrication plant in San Antonio in 1981. In 1980, AMD began supplying semiconductor products for telecommunications, an industry undergoing rapid expansion and innovation. Technology exchange agreement with Intel Intel had introduced the first x86 microprocessors in 1978. In 1981, IBM created its PC, and wanted Intel's x86 processors, but only under the condition that Intel also provide a second-source manufacturer for its patented x86 microprocessors. Intel and AMD entered into a 10-year technology exchange agreement, first signed in October 1981 and formally executed in February 1982. The terms of the agreement were that each company could acquire the right to become a second-source manufacturer of semiconductor products developed by the other; that is, each party could "earn" the right to manufacture and sell a product developed by the other, if agreed to, by exchanging the manufacturing rights to a product of equivalent technical complexity. The technical information and licenses needed to make and sell a part would be exchanged for a royalty to the developing company. The 1982 agreement also extended the 1976 AMD–Intel cross-licensing agreement through 1995. The agreement included the right to invoke arbitration of disagreements, and after five years the right of either party to end the agreement with one year's notice. The main result of the 1982 agreement was that AMD became a second-source manufacturer of Intel's x86 microprocessors and related chips, and Intel provided AMD with database tapes for its 8086, 80186, and 80286 chips. However, in the event of a bankruptcy or takeover of AMD, the cross-licensing agreement would be effectively canceled. Beginning in 1982, AMD began volume-producing second-source Intel-licensed 8086, 8088, 80186, and 80188 processors, and by 1984, its own Am286 clone of Intel's 80286 processor, for the rapidly growing market of IBM PCs and IBM clones. It also continued its successful concentration on proprietary bipolar chips. The company continued to spend greatly on research and development, and created the world's first 512K EPROM in 1984. That year, AMD was listed in the book The 100 Best Companies to Work for in America, and later made the Fortune 500 list for the first time in 1985. By mid-1985, the microchip market experienced a severe downturn, mainly due to long-term aggressive trade practices (dumping) from Japan, but also due to a crowded and non-innovative chip market in the United States. AMD rode out the mid-1980s crisis by aggressively innovating and modernizing, devising the Liberty Chip program of designing and manufacturing one new chip or chipset per week for 52 weeks in fiscal year 1986, and by heavily lobbying the U.S. government until sanctions and restrictions were put in place to prevent predatory Japanese pricing. During this time, AMD withdrew from the DRAM market, and made some headway into the CMOS market, which it had lagged in entering, having focused instead on bipolar chips. AMD had some success in the mid-1980s with the AMD7910 and AMD7911 "World Chip" FSK modem, one of the first multi-standard devices that covered both Bell and CCITT tones at up to 1200 baud half duplex or 300/300 full duplex. Beginning in 1986, AMD embraced the perceived shift toward RISC with their own AMD Am29000 (29k) processor; the 29k survived as an embedded processor. The company also increased its EPROM memory market share in the late 1980s. Throughout the 1980s, AMD was a second-source supplier of Intel x86 processors. In 1991, it introduced its own 386-compatible Am386, an AMD-designed chip. Creating its own chips, AMD began to compete directly with Intel. AMD had a large, successful flash memory business, even during the dotcom bust. In 2003, to divest some manufacturing and aid its overall cash flow, which was under duress from aggressive microprocessor competition from Intel, AMD spun off its flash memory business and manufacturing into Spansion, a joint venture with Fujitsu, which had been co-manufacturing flash memory with AMD since 1993. In December 2005, AMD divested itself of Spansion to focus on the microprocessor market, and Spansion went public in an IPO. Acquisition of ATI, spin-off of GlobalFoundries, and acquisition of Xilinx On July 24, 2006, AMD announced its acquisition of the Canadian 3D graphics card company ATI Technologies. AMD paid $4.3 billion and 58 million shares of its capital stock, for a total of approximately $5.4 billion. The transaction was completed on October 25, 2006. On August 30, 2010, AMD announced that it would retire the ATI brand name for its graphics chipsets in favor of the AMD brand name. In October 2008, AMD announced plans to spin off manufacturing operations in the form of GlobalFoundries Inc., a multibillion-dollar joint venture with Advanced Technology Investment Co., an investment company formed by the government of Abu Dhabi. The partnership and spin-off gave AMD an infusion of cash and allowed it to focus solely on chip design. To assure the Abu Dhabi investors of the new venture's success, AMD's CEO Hector Ruiz stepped down in July 2008, while remaining executive chairman, in preparation for becoming chairman of GlobalFoundries in March 2009. President and COO Dirk Meyer became AMD's CEO. Recessionary losses necessitated AMD cutting 1,100 jobs in 2009. In August 2011, AMD announced that former Lenovo executive Rory Read would be joining the company as CEO, replacing Meyer. In November 2011, AMD announced plans to lay off more than 10% (1,400) of its employees from across all divisions worldwide. In October 2012, it announced plans to lay off an additional 15% of its workforce to reduce costs in the face of declining sales revenue. AMD acquired the low-power server manufacturer SeaMicro in early 2012, with an eye to bringing out an Arm64 server chip. On October 8, 2014, AMD announced that Rory Read had stepped down after three years as president and chief executive officer. He was succeeded by Lisa Su, a key lieutenant who had been serving as chief operating officer since June. On October 16, 2014, AMD announced a new restructuring plan along with its Q3 results. Effective July 1, 2014, AMD reorganized into two business groups: Computing and Graphics, which primarily includes desktop and notebook processors and chipsets, discrete GPUs, and professional graphics; and Enterprise, Embedded, and Semi-Custom, which primarily includes server and embedded processors, dense servers, semi-custom SoC products (including solutions for gaming consoles), engineering services, and royalties. As part of this restructuring, AMD announced that 7% of its global workforce would be laid off by the end of 2014. After the GlobalFoundries spin-off and subsequent layoffs, AMD was left with significant vacant space at 1 AMD Place, its aging Sunnyvale headquarters office complex. In August 2016, AMD's 47 years in Sunnyvale came to a close when it signed a lease with the Irvine Company for a new 220,000 sq. ft. headquarters building in Santa Clara. AMD's new location at Santa Clara Square faces the headquarters of archrival Intel across the Bayshore Freeway and San Tomas Aquino Creek. Around the same time, AMD also agreed to sell 1 AMD Place to the Irvine Company. In April 2019, the Irvine Company secured approval from the Sunnyvale City Council of its plans to demolish 1 AMD Place and redevelop the entire 32-acre site into townhomes and apartments. In October 2020, AMD announced that it was acquiring Xilinx in an all-stock transaction. The acquisition was completed in February 2022, with an estimated acquisition price of $50 billion. In October 2023, AMD acquired an open-source AI software provider, Nod.ai, to bolster its AI software ecosystem. List of CEOs Products CPUs and APUs IBM PC and the x86 architecture In February 1982, AMD signed a contract with Intel, becoming a licensed second-source manufacturer of 8086 and 8088 processors. IBM wanted to use the Intel 8088 in its IBM PC, but its policy at the time was to require at least two sources for its chips. AMD later produced the Am286 under the same arrangement. In 1984, Intel internally decided to no longer cooperate with AMD in supplying product information to shore up its advantage in the marketplace, and delayed and eventually refused to convey the technical details of the Intel 80386. In 1987, AMD invoked arbitration over the issue, and Intel reacted by canceling the 1982 technological-exchange agreement altogether. After three years of testimony, AMD eventually won in arbitration in 1992, but Intel disputed this decision. Another long legal dispute followed, ending in 1994 when the Supreme Court of California sided with the arbitrator and AMD. In 1990, Intel countersued AMD, renegotiating AMD's right to use derivatives of Intel's microcode for its cloned processors. In the face of uncertainty during the legal dispute, AMD was forced to develop clean room designed versions of Intel code for its x386 and x486 processors, the former long after Intel had released its own x386 in 1985. In March 1991, AMD released the Am386, its clone of the Intel 386 processor. By October of the same year it had sold one million units. In 1993, AMD introduced the first of the Am486 family of processors, which proved popular with a large number of original equipment manufacturers, including Compaq, which signed an exclusive agreement using the Am486. The Am5x86, another Am486-based processor, was released in November 1995, and continued AMD's success as a fast, cost-effective processor. Finally, in an agreement effective 1996, AMD received the rights to the microcode in Intel's x386 and x486 processor families, but not the rights to the microcode in the following generations of processors. K5, K6, Athlon, Duron, and Sempron AMD's first in-house x86 processor was the K5, launched in 1996. The "K" in its name was a reference to Kryptonite, the only substance known to harm comic book character Superman. This itself was a reference to Intel's hegemony over the market, i.e., an anthropomorphization of them as Superman. The number "5" was a reference to the fifth generation of x86 processors; rival Intel had previously introduced its line of fifth-generation x86 processors as Pentium because the U.S. Trademark and Patent Office had ruled that mere numbers could not be trademarked. In 1996, AMD purchased NexGen, specifically for the rights to their Nx series of x86-compatible processors. AMD gave the NexGen design team their own building, left them alone, and gave them time and money to rework the Nx686. The result was the K6 processor, introduced in 1997. Although it was based on Socket 7, variants such as K6-III/450 were faster than Intel's Pentium II (sixth-generation processor). The K7 was AMD's seventh-generation x86 processor, making its debut under the brand name Athlon on June 23, 1999. Unlike previous AMD processors, it could not be used on the same motherboards as Intel's, due to licensing issues surrounding Intel's Slot 1 connector, and instead used a Slot A connector, referenced to the Alpha processor bus. The Duron was a lower-cost and limited version of the Athlon (64KB instead of 256KB L2 cache) in a 462-pin socketed PGA (socket A) or soldered directly onto the motherboard. Sempron was released as a lower-cost Athlon XP, replacing Duron in the socket A PGA era. It has since been migrated upward to all new sockets, up to AM3. On October 9, 2001, the Athlon XP was released. On February 10, 2003, the Athlon XP with 512KB L2 Cache was released. Athlon 64, Opteron and Phenom The K8 was a major revision of the K7 architecture, with the most notable features being the addition of a 64-bit extension to the x86 instruction set (called x86-64, AMD64, or x64), the incorporation of an on-chip memory controller, and the implementation of an extremely high-performance point-to-point interconnect called HyperTransport, as part of the Direct Connect Architecture. The technology was initially launched as the Opteron server-oriented processor on April 22, 2003. Shortly thereafter, it was incorporated into a product for desktop PCs, branded Athlon 64. On April 21, 2005, AMD released the first dual-core Opteron, an x86-based server CPU. A month later, it released the Athlon 64 X2, the first desktop-based dual-core processor family. In May 2007, AMD abandoned the string "64" in its dual-core desktop product branding, becoming Athlon X2, downplaying the significance of 64-bit computing in its processors. Further updates involved improvements to the microarchitecture, and a shift of the target market from mainstream desktop systems to value dual-core desktop systems. In 2008, AMD started to release dual-core Sempron processors exclusively in China, branded as the Sempron 2000 series, with lower HyperTransport speed and smaller L2 cache. AMD completed its dual-core product portfolio for each market segment. In September 2007, AMD released the first server Opteron K10 processors, followed in November by the Phenom processor for desktop. K10 processors came in dual-core, triple-core, and quad-core versions, with all cores on a single die. AMD released a new platform codenamed "Spider", which used the new Phenom processor, as well as an R770 GPU and a 790 GX/FX chipset from the AMD 700 chipset series. However, AMD built the Spider at 65nm, which was uncompetitive with Intel's smaller and more power-efficient 45nm. In January 2009, AMD released a new processor line dubbed Phenom II, a refresh of the original Phenom built using the 45 nm process. AMD's new platform, codenamed "Dragon", used the new Phenom II processor, and an ATI R770 GPU from the R700 GPU family, as well as a 790 GX/FX chipset from the AMD 700 chipset series. The Phenom II came in dual-core, triple-core and quad-core variants, all using the same die, with cores disabled for the triple-core and dual-core versions. The Phenom II resolved issues that the original Phenom had, including a low clock speed, a small L3 cache, and a Cool'n'Quiet bug that decreased performance. The Phenom II cost less but was not performance-competitive with Intel's mid-to-high-range Core 2 Quads. The Phenom II also enhanced its predecessor's memory controller, allowing it to use DDR3 in a new native socket AM3, while maintaining backward compatibility with AM2+, the socket used for the Phenom, and allowing the use of the DDR2 memory that was used with the platform. In April 2010, AMD released a new Phenom II Hexa-core (6-core) processor codenamed "Thuban". This was a totally new die based on the hexa-core "Istanbul" Opteron processor. It included AMD's "turbo core" technology, which allows the processor to automatically switch from 6 cores to 3 faster cores when more pure speed is needed. The Magny Cours and Lisbon server parts were released in 2010. The Magny Cours part came in 8 to 12 cores and the Lisbon part in 4 and 6 core parts. Magny Cours is focused on performance while the Lisbon part is focused on high performance per watt. Magny Cours is an MCM (multi-chip module) with two hexa-core "Istanbul" Opteron parts. This will use a new socket G34 for dual and quad-socket processors and thus will be marketed as Opteron 61xx series processors. Lisbon uses socket C32 certified for dual-socket use or single socket use only and thus will be marketed as Opteron 41xx processors. Both will be built on a 45 nm SOI process. Fusion becomes the AMD APU Following AMD's 2006 acquisition of Canadian graphics company ATI Technologies, an initiative codenamed Fusion was announced to integrate a CPU and GPU together on some of AMD's microprocessors, including a built in PCI Express link to accommodate separate PCI Express peripherals, eliminating the northbridge chip from the motherboard. The initiative intended to move some of the processing originally done on the CPU (e.g. floating-point unit operations) to the GPU, which is better optimized for some calculations. The Fusion was later renamed the AMD APU (Accelerated Processing Unit). Llano was AMD's first APU built for laptops. Llano was the second APU released, targeted at the mainstream market. It incorporated a CPU and GPU on the same die, as well as northbridge functions, and used "Socket FM1" with DDR3 memory. The CPU part of the processor was based on the Phenom II "Deneb" processor. AMD suffered an unexpected decrease in revenue based on production problems for the Llano. More AMD APUs for laptops running Windows 7 and Windows 8 OS are being used commonly. These include AMD's price-point APUs, the E1 and E2, and their mainstream competitors with Intel's Core i-series: The Vision A- series, the A standing for accelerated. These range from the lower-performance A4 chipset to the A6, A8, and A10. These all incorporate next-generation Radeon graphics cards, with the A4 utilizing the base Radeon HD chip and the rest using a Radeon R4 graphics card, with the exception of the highest-model A10 (A10-7300) which uses an R6 graphics card. New microarchitectures High-power, high-performance Bulldozer cores Bulldozer was AMD's microarchitecture codename for server and desktop AMD FX processors, first released on October 12, 2011. This family 15h microarchitecture is the successor to the family 10h (K10) microarchitecture design. Bulldozer was a clean-sheet design, not a development of earlier processors. The core was specifically aimed at 10–125 W TDP computing products. AMD claimed dramatic performance-per-watt efficiency improvements in high-performance computing (HPC) applications with Bulldozer cores. While hopes were high that Bulldozer would bring AMD to be performance-competitive with Intel once more, most benchmarks were disappointing. In some cases the new Bulldozer products were slower than the K10 models they were built to replace. The Piledriver microarchitecture was the 2012 successor to Bulldozer, increasing clock speeds and performance relative to its predecessor. Piledriver would be released in AMD FX, APU, and Opteron product lines. Piledriver was subsequently followed by the Steamroller microarchitecture in 2013. Used exclusively in AMD's APUs, Steamroller focused on greater parallelism. In 2015, the Excavator microarchitecture replaced Piledriver. Expected to be the last microarchitecture of the Bulldozer series, Excavator focused on improved power efficiency. Low-power Cat cores The Bobcat microarchitecture was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 and was put into production during the first quarter of 2011. Based on the difficulty competing in the x86 market with a single core optimized for the 10–100 W range, AMD had developed a simpler core with a target range of 1–10 watts. In addition, it was believed that the core could migrate into the hand-held space if the power consumption can be reduced to less than 1 W. Jaguar is a microarchitecture codename for Bobcat's successor, released in 2013, that is used in various APUs from AMD aimed at the low-power/low-cost market. Jaguar and its derivates would go on to be used in the custom APUs of the PlayStation 4, Xbox One, PlayStation 4 Pro, Xbox One S, and Xbox One X. Jaguar would be later followed by the Puma microarchitecture in 2014. ARM architecture-based designs In 2012, AMD announced it was working on ARM products, both as a semi-custom product and server product. The initial server product was announced as the Opteron A1100 in 2014, an 8-core Cortex-A57 based ARMv8-A SoC, and was expected to be followed by an APU incorporating a Graphics Core Next GPU. However, the Opteron A1100 was not released until 2016, with the delay attributed to adding software support. The A1100 was also criticized for not having support from major vendors upon its release. In 2014, AMD also announced the K12 custom core for release in 2016. While being ARMv8-A instruction set architecture compliant, the K12 was expected to be entirely custom-designed, targeting the server, embedded, and semi-custom markets. While ARM architecture development continued, products based on K12 were subsequently delayed with no release planned. Development of AMD's x86-based Zen microarchitecture was preferred. Zen-based CPUs and APUs Zen is a new architecture for x86-64 based Ryzen series of CPUs and APUs, introduced in 2017 by AMD and built from the ground up by a team led by Jim Keller, beginning with his arrival in 2012, and taping out before his departure in September 2015. One of AMD's primary goals with Zen was an IPC increase of at least 40%, however in February 2017 AMD announced that they had actually achieved a 52% increase. Processors made on the Zen architecture are built on the 14 nm FinFET node and have a renewed focus on single-core performance and HSA compatibility. Previous processors from AMD were either built in the 32 nm process ("Bulldozer" and "Piledriver" CPUs) or the 28 nm process ("Steamroller" and "Excavator" APUs). Because of this, Zen is much more energy efficient. The Zen architecture is the first to encompass CPUs and APUs from AMD built for a single socket (Socket AM4). Also new for this architecture is the implementation of simultaneous multithreading (SMT) technology, something Intel has had for years on some of their processors with their proprietary hyper-threading implementation of SMT. This is a departure from the "Clustered MultiThreading" design introduced with the Bulldozer architecture. Zen also has support for DDR4 memory. AMD released the Zen-based high-end Ryzen 7 "Summit Ridge" series CPUs on March 2, 2017, mid-range Ryzen 5 series CPUs on April 11, 2017, and entry level Ryzen 3 series CPUs on July 27, 2017. AMD later released the Epyc line of Zen derived server processors for 1P and 2P systems. In October 2017, AMD released Zen-based APUs as Ryzen Mobile, incorporating Vega graphics cores. In January 2018 AMD has announced their new lineup plans, with Ryzen 2. AMD launched CPUs with the 12nm Zen+ microarchitecture in April 2018, following up with the 7nm Zen 2 microarchitecture in June 2019, including an update to the Epyc line with new processors using the Zen 2 microarchitecture in August 2019, and Zen 3 slated for release in Q3 2020. As of 2019, AMD's Ryzen processors were reported to outsell Intel's consumer desktop processors. At CES 2020 AMD announced their Ryzen Mobile 4000, as the first 7 nm x86 mobile processor, the first 7 nm 8-core (also 16-thread) high-performance mobile processor, and the first 8-core (also 16-thread) processor for ultrathin laptops. This generation is still based on the Zen 2 architecture. In October 2020, AMD announced new processors based on the Zen 3 architecture. On PassMark's Single thread performance test the Ryzen 5 5600x bested all other CPUs besides the Ryzen 9 5950X. In August 2022, AMD announced their initial lineup of CPUs based on the new Zen 4 architecture. The Steam Deck, PlayStation 5, Xbox Series X and Series S all use chips based on the Zen 2 microarchitecture, with proprietary tweaks and different configurations in each system's implementation than AMD sells in its own commercially available APUs. Graphics products and GPUs ATI prior to AMD acquisition Radeon within AMD In 2008, the ATI division of AMD released the TeraScale microarchitecture implementing a unified shader model. This design replaced the previous fixed-function hardware of previous graphics cards with multipurpose, programmable shaders. Initially released as part of the GPU for the Xbox 360, this technology would go on to be used in Radeon branded HD 2000 parts. Three generations of TeraScale would be designed and used in parts from 2008 to 2014. Combined GPU and CPU divisions In a 2009 restructuring, AMD merged the CPU and GPU divisions to support the company's APUs, which fused both graphics and general purpose processing. In 2011, AMD released the successor to TeraScale, Graphics Core Next (GCN). This new microarchitecture emphasized GPGPU compute capability in addition to graphics processing, with a particular aim of supporting heterogeneous computing on AMD's APUs. GCN's reduced instruction set ISA allowed for significantly increased compute capability over TeraScale's very long instruction word ISA. Since GCN's introduction with the HD 7970, five generations of the GCN architecture have been produced from 2008 through at least 2017. Radeon Technologies Group In September 2015, AMD separated the graphics technology division of the company into an independent internal unit called the Radeon Technologies Group (RTG) headed by Raja Koduri. This gave the graphics division of AMD autonomy in product design and marketing. The RTG then went on to create and release the Polaris and Vega microarchitectures released in 2016 and 2017, respectively. In particular the Vega, or fifth generation GCN, microarchitecture includes a number of major revisions to improve performance and compute capabilities. In November 2017, Raja Koduri left RTG and CEO and President Lisa Su took his position. In January 2018, it was reported that two industry veterans joined RTG, namely Mike Rayfield as senior vice president and general manager of RTG, and David Wang as senior vice president of engineering for RTG. In January 2020, AMD announced that its second generation RDNA graphics architecture was in development, with the aim of competing with the Nvidia RTX graphics products for performance leadership. In October 2020, AMD announced their new RX 6000 series series GPUs, their first high-end product based on RDNA2 and capable of handling ray-tracing natively, aiming to challenge Nvidia's RTX 3000 GPUs. Semi-custom and game console products In 2012, AMD's then CEO Rory Read began a program to offer semi-custom designs. Rather than AMD simply designing and offering a single product, potential customers could work with AMD to design a custom chip based on AMD's intellectual property. Customers pay a non-recurring engineering fee for design and development, and a purchase price for the resulting semi-custom products. In particular, AMD noted their unique position of offering both x86 and graphics intellectual property. These semi-custom designs would have design wins as the APUs in the PlayStation 4 and Xbox One and the subsequent PlayStation 4 Pro, Xbox One S, Xbox One X, Xbox Series X/S, and PlayStation 5. Financially, these semi-custom products would represent a majority of the company's revenue in 2016. In November 2017, AMD and Intel announced that Intel would market a product combining in a single package an Intel Core CPU, a semi-custom AMD Radeon GPU, and HBM2 memory. Other hardware AMD motherboard chipsets Before the launch of Athlon 64 processors in 2003, AMD designed chipsets for their processors spanning the K6 and K7 processor generations. The chipsets include the AMD-640, AMD-751, and the AMD-761 chipsets. The situation changed in 2003 with the release of Athlon 64 processors, and AMD chose not to further design its own chipsets for its desktop processors while opening the desktop platform to allow other firms to design chipsets. This was the "Open Platform Management Architecture" with ATI, VIA and SiS developing their own chipset for Athlon 64 processors and later Athlon 64 X2 and Athlon 64 FX processors, including the Quad FX platform chipset from Nvidia. The initiative went further with the release of Opteron server processors as AMD stopped the design of server chipsets in 2004 after releasing the AMD-8111 chipset, and again opened the server platform for firms to develop chipsets for Opteron processors. As of today, Nvidia and Broadcom are the sole designing firms of server chipsets for Opteron processors. As the company completed the acquisition of ATI Technologies in 2006, the firm gained the ATI design team for chipsets which previously designed the Radeon Xpress 200 and the Radeon Xpress 3200 chipsets. AMD then renamed the chipsets for AMD processors under AMD branding (for instance, the CrossFire Xpress 3200 chipset was renamed as AMD 580X CrossFire chipset). In February 2007, AMD announced the first AMD-branded chipset since 2004 with the release of the AMD 690G chipset (previously under the development codename RS690), targeted at mainstream IGP computing. It was the industry's first to implement a HDMI 1.2 port on motherboards, shipping for more than a million units. While ATI had aimed at releasing an Intel IGP chipset, the plan was scrapped and the inventories of Radeon Xpress 1250 (codenamed RS600, sold under ATI brand) was sold to two OEMs, Abit and ASRock. Although AMD stated the firm would still produce Intel chipsets, Intel had not granted the license of FSB to ATI. On November 15, 2007, AMD announced a new chipset series portfolio, the AMD 7-Series chipsets, covering from the enthusiast multi-graphics segment to the value IGP segment, to replace the AMD 480/570/580 chipsets and AMD 690 series chipsets, marking AMD's first enthusiast multi-graphics chipset. Discrete graphics chipsets were launched on November 15, 2007, as part of the codenamed Spider desktop platform, and IGP chipsets were launched at a later time in spring 2008 as part of the codenamed Cartwheel platform. AMD returned to the server chipsets market with the AMD 800S series server chipsets. It includes support for up to six SATA 6.0 Gbit/s ports, the C6 power state, which is featured in Fusion processors and AHCI 1.2 with SATA FIS–based switching support. This is a chipset family supporting Phenom processors and Quad FX enthusiast platform (890FX), IGP (890GX). With the advent of AMD's APUs in 2011, traditional northbridge features such as the connection to graphics and the PCI Express controller were incorporated into the APU die. Accordingly, APUs were connected to a single chip chipset, renamed the Fusion Controller Hub (FCH), which primarily provided southbridge functionality. AMD released new chipsets in 2017 to support the release of their new Ryzen products. As the Zen microarchitecture already includes much of the northbridge connectivity, the AM4-based chipsets primarily varied in the number of additional PCI Express lanes, USB connections, and SATA connections available. These AM4 chipsets were designed in conjunction with ASMedia. Embedded products Embedded CPUs In the early 1990s, AMD began marketing a series of embedded System-on-a-chip (SoC) called AMD Élan, starting with the SC300 and SC310. Both combines a 32-Bit, Am386SX, low-voltage 25 MHz or 33 MHz CPU with memory controller, PC/AT peripheral controllers, real-time clock, PLL clock generators and ISA bus interface. The SC300 integrates in addition two PC card slots and a CGA-compatible LCD controller. They were followed in 1996 by the SC4xx types. Now supporting VESA Local Bus and using the Am486 with up to 100 MHz clock speed. A SC450 with 33 MHze.g. was used in the Nokia 9000 Communicator. In 1999 the SC520 was announced. Using an Am586 with 100 MHz or 133 MHz and supporting SDRAM and PCI it was the latest member of the series. In February 2002, AMD acquired Alchemy Semiconductor for its Alchemy line of MIPS processors for the hand-held and portable media player markets. On June 13, 2006, AMD officially announced that the line was to be transferred to Raza Microelectronics, Inc., a designer of MIPS processors for embedded applications. In August 2003, AMD also purchased the Geode business which was originally the Cyrix MediaGX from National Semiconductor to augment its existing line of embedded x86 processor products. During the second quarter of 2004, it launched new low-power Geode NX processors based on the K7 Thoroughbred architecture with speeds of fanless processors and , and processor with fan, of TDP 25 W. This technology is used in a variety of embedded systems (Casino slot machines and customer kiosks for instance), several UMPC designs in Asia markets, as well as the OLPC XO-1 computer, an inexpensive laptop computer intended to be distributed to children in developing countries around the world. The Geode LX processor was announced in 2005 and is said will continue to be available through 2015. AMD has also introduced 64-bit processors into its embedded product line starting with the AMD Opteron processor. Leveraging the high throughput enabled through HyperTransport and the Direct Connect Architecture these server-class processors have been targeted at high-end telecom and storage applications. In 2007, AMD added the AMD Athlon, AMD Turion, and Mobile AMD Sempron processors to its embedded product line. Leveraging the same 64-bit instruction set and Direct Connect Architecture as the AMD Opteron but at lower power levels, these processors were well suited to a variety of traditional embedded applications. Throughout 2007 and into 2008, AMD has continued to add both single-core Mobile AMD Sempron and AMD Athlon processors and dual-core AMD Athlon X2 and AMD Turion processors to its embedded product line and now offers embedded 64-bit solutions starting with 8 W TDP Mobile AMD Sempron and AMD Athlon processors for fan-less designs up to multi-processor systems leveraging multi-core AMD Opteron processors all supporting longer than standard availability. The ATI acquisition in 2006 included the Imageon and Xilleon product lines. In late 2008, the entire handheld division was sold off to Qualcomm, who have since produced the Adreno series. Also in 2008, the Xilleon division was sold to Broadcom. In April 2007, AMD announced the release of the M690T integrated graphics chipset for embedded designs. This enabled AMD to offer complete processor and chipset solutions targeted at embedded applications requiring high-performance 3D and video such as emerging digital signage, kiosk, and Point of Sale applications. The M690T was followed by the M690E specifically for embedded applications which removed the TV output, which required Macrovision licensing for OEMs, and enabled native support for dual TMDS outputs, enabling dual independent DVI interfaces. In January 2011, AMD announced the AMD Embedded G-Series Accelerated Processing Unit. This was the first APU for embedded applications. These were followed by updates in 2013 and 2016. In May 2012, AMD Announced the AMD Embedded R-Series Accelerated Processing Unit. This family of products incorporates the Bulldozer CPU architecture, and Discrete-class Radeon HD 7000G Series graphics. This was followed by a system on a chip (SoC) version in 2015 which offered a faster CPU and faster graphics, with support for DDR4 SDRAM memory. Embedded graphics AMD builds graphic processors for use in embedded systems. They can be found in anything from casinos to healthcare, with a large portion of products being used in industrial machines. These products include a complete graphics processing device in a compact multi-chip module including RAM and the GPU. ATI began offering embedded GPUs with the E2400 in 2008. Since that time AMD has released regular updates to their embedded GPU lineup in 2009, 2011, 2015, and 2016; reflecting improvements in their GPU technology.

Radeon Instinct – brand of server and workstation targeted machine learning and GPGPU products Radeon-branded products RAM In 2011, AMD began selling Radeon branded DDR3 SDRAM to support the higher bandwidth needs of AMD's APUs. While the RAM is sold by AMD, it was manufactured by Patriot Memory and VisionTek. This was later followed by higher speeds of gaming oriented DDR3 memory in 2013. Radeon branded DDR4 SDRAM memory was released in 2015, despite no AMD CPUs or APUs supporting DDR4 at the time. AMD noted in 2017 that these products are "mostly distributed in Eastern Europe" and that it continues to be active in the business. Solid-state drives AMD announced in 2014 it would sell Radeon branded solid-state drives manufactured by OCZ with capacities up to 480 GB and using the SATA interface. Technologies CPU hardware technologies found in AMD CPU/APU and other products include: HyperTransport – a high-bandwidth, low-latency system bus used in AMD's CPU and APU products Infinity Fabric – a derivative of HyperTransport used as the communication bus in AMD's Zen microarchitecture Graphics hardware technologies found in AMD GPU products include: AMD Eyefinity – facilitates multi-monitor setup of up to 6 monitors per graphics card AMD FreeSync – display synchronization based on the VESA Adaptive Sync standard AMD TrueAudio – acceleration of audio calculations AMD XConnect – allows the use of External GPU enclosures through Thunderbolt 3 AMD CrossFire – multi-GPU technology allowing the simultaneous use of multiple GPUs Unified Video Decoder (UVD) – acceleration of video decompression (decoding) Video Coding Engine (VCE) – acceleration of video compression (encoding) Software AMD has made considerable efforts towards opening its software tools above the firmware level in the past decade. For the following mentions, software not expressely stated free can be assumed to be proprietary. Distribution AMD Radeon Software is the default channel for official software distribution from AMD. It includes both free and proprietary software components, and supports both Microsoft Windows and Linux. Software by type CPU AOCC is AMD's optimizing proprietary C/C++ compiler based on LLVM and available for Linux. AMDuProf is AMD's CPU performance and Power profiling tool suite, available for Linux and Windows. AMD has also taken an active part in developing coreboot, an open-source project aimed at replacing the proprietary BIOS firmware. This cooperation ceased in 2013, but AMD has indicated recently that it is considering releasing source code so that Ryzen can be compatible with coreboot in the future. GPU Most notable public AMD software is on the GPU side. AMD has opened both its graphic and compute stacks: GPUOpen is AMD's graphics stack, which includes for example FidelityFX Super Resolution. ROCm (Radeon Open Compute platform) is AMD's compute stack for machine learning and high-performance computing, based on the LLVM compiler technologies. Under the ROCm project, AMDgpu is AMD's open source device driver supporting the GCN and following architectures, available for Linux. This latter driver component is used both by the graphics and compute stacks. Misc AMD conducts open research on heterogeneous computing. Other AMD software includes the AMD Core Math Library, and open-source software including the AMD Performance Library. AMD contributes to open source projects, including working with Sun Microsystems to enhance OpenSolaris and Sun xVM on the AMD platform. AMD also maintains its own Open64 compiler distribution and contributes its changes back to the community. In 2008, AMD released the low-level programming specifications for its GPUs, and works with the X.Org Foundation to develop drivers for AMD graphics cards. Extensions for software parallelism (xSP), aimed at speeding up programs to enable multi-threaded and multi-core processing, announced in Technology Analyst Day 2007. One of the initiatives being discussed since August 2007 is the Light Weight Profiling (LWP), providing internal hardware monitor with runtimes, to observe information about executing process and help the re-design of software to be optimized with multi-core and even multi-threaded programs. Another one is the extension of Streaming SIMD Extension (SSE) instruction set, the SSE5. Codenamed SIMFIRE – interoperability testing tool for the Desktop and mobile Architecture for System Hardware (DASH) open architecture. Production and fabrication Previously, AMD produced its chips at company-owned semiconductor foundries. AMD pursued a strategy of collaboration with other semiconductor manufacturers IBM and Motorola to co-develop production technologies. AMD's founder Jerry Sanders termed this the "Virtual Gorilla" strategy to compete with Intel's significantly greater investments in fabrication. In 2008, AMD spun off its chip foundries into an independent company named GlobalFoundries. This breakup of the company was attributed to the increasing costs of each process node. The Emirate of Abu Dhabi purchased the newly created company through its subsidiary Advanced Technology Investment Company (ATIC), purchasing the final stake from AMD in 2009. With the spin-off of its foundries, AMD became a fabless semiconductor manufacturer, designing products to be produced at for-hire foundries. Part of the GlobalFoundries spin-off included an agreement with AMD to produce some number of products at GlobalFoundries. Both prior to the spin-off and after AMD has pursued production with other foundries including TSMC and Samsung. It has been argued that this would reduce risk for AMD by decreasing dependence on any one foundry which has caused issues in the past. In 2018, AMD started shifting the production of their CPUs and GPUs to TSMC, following GlobalFoundries' announcement that they were halting development of their 7 nm process. AMD revised their wafer purchase requirement with GlobalFoundries in 2019, allowing AMD to freely choose foundries for 7 nm nodes and below, while maintaining purchase agreements for 12 nm and above through 2021. Corporate affairs Partnerships AMD uses strategic industry partnerships to further its business interests as well as to rival Intel's dominance and resources: A partnership between AMD and Alpha Processor Inc. developed HyperTransport, a point-to-point interconnect standard which was turned over to an industry standards body for finalization. It is now used in modern motherboards that are compatible with AMD processors. AMD also formed a strategic partnership with IBM, under which AMD gained silicon on insulator (SOI) manufacturing technology, and detailed advice on 90 nm implementation. AMD announced that the partnership would extend to 2011 for 32 nm and 22 nm fabrication-related technologies. To facilitate processor distribution and sales, AMD is loosely partnered with end-user companies, such as HP, Dell, Asus, Acer, and Microsoft. In 1993, AMD established a 50–50 partnership with Fujitsu called FASL, and merged into a new company called FASL LLC in 2003. The joint venture went public under the name Spansion and ticker symbol SPSN in December 2005, with AMD shares dropping 37%. AMD no longer directly participates in the Flash memory devices market now as AMD entered into a non-competition agreement on December 21, 2005, with Fujitsu and Spansion, pursuant to which it agreed not to directly or indirectly engage in a business that manufactures or supplies standalone semiconductor devices (including single-chip, multiple-chip or system devices) containing only Flash memory. On May 18, 2006, Dell announced that it would roll out new servers based on AMD's Opteron chips by year's end, thus ending an exclusive relationship with Intel. In September 2006, Dell began offering AMD Athlon X2 chips in their desktop lineup. In June 2011, HP announced new business and consumer notebooks equipped with the latest versions of AMD APUsaccelerated processing units. AMD will power HP's Intel-based business notebooks as well. In the spring of 2013, AMD announced that it would be powering all three major next-generation consoles. The Xbox One and Sony PlayStation 4 are both powered by a custom-built AMD APU, and the Nintendo Wii U is powered by an AMD GPU. According to AMD, having their processors in all three of these consoles will greatly assist developers with cross-platform development to competing consoles and PCs as well as increased support for their products across the board. AMD has entered into an agreement with Hindustan Semiconductor Manufacturing Corporation (HSMC) for the production of AMD products in India. AMD is a founding member of the HSA Foundation which aims to ease the use of a Heterogeneous System Architecture. A Heterogeneous System Architecture is intended to use both central processing units and graphics processors to complete computational tasks. AMD announced in 2016 that it was creating a joint venture to produce x86 server chips for the Chinese market. On May 7, 2019, it was reported that the U.S. Department of Energy, Oak Ridge National Laboratory, and Cray Inc., are working in collaboration with AMD to develop the Frontier exascale supercomputer. Featuring the AMD Epyc CPUs and Radeon GPUs, the supercomputer is set to produce more than 1.5 exaflops (peak double-precision) in computing performance. It is expected to debut sometime in 2021. On March 5, 2020, it was announced that the U.S. Department of Energy, Lawrence Livermore National Laboratory, and HPE are working in collaboration with AMD to develop the El Capitan exascale supercomputer. Featuring the AMD Epyc CPUs and Radeon GPUs, the supercomputer is set to produce more than 2 exaflops (peak double-precision) in computing performance. It is expected to debut in 2023. In the summer of 2020, it was reported that AMD would be powering the next-generation console offerings from Microsoft and Sony. On November 8, 2021, AMD announced a partnership with Meta to make the chips used in the Metaverse. In January 2022, AMD partnered with Samsung to develop a mobile processor to be used in future products. The processor was named Exynos 2022 and works with the AMD RDNA 2 architecture. Litigation with Intel AMD has a long history of litigation with former (and current) partner and x86 creator Intel. In 1986, Intel broke an agreement it had with AMD to allow them to produce Intel's microchips for IBM; AMD filed for arbitration in 1987 and the arbitrator decided in AMD's favor in 1992. Intel disputed this, and the case ended up in the Supreme Court of California. In 1994, that court upheld the arbitrator's decision and awarded damages for breach of contract. In 1990, Intel brought a copyright infringement action alleging illegal use of its 287 microcode. The case ended in 1994 with a jury finding for AMD and its right to use Intel's microcode in its microprocessors through the 486 generation. In 1997, Intel filed suit against AMD and Cyrix Corp. for misuse of the term MMX. AMD and Intel settled, with AMD acknowledging MMX as a trademark owned by Intel, and with Intel granting AMD rights to market the AMD K6 MMX processor. In 2005, following an investigation, the Japan Federal Trade Commission found Intel guilty of a number of violations. On June 27, 2005, AMD won an antitrust suit against Intel in Japan, and on the same day, AMD filed a broad antitrust complaint against Intel in the U.S. Federal District Court in Delaware. The complaint alleges systematic use of secret rebates, special discounts, threats, and other means used by Intel to lock AMD processors out of the global market. Since the start of this action, the court has issued subpoenas to major computer manufacturers including Acer, Dell, Lenovo, HP and Toshiba. In November 2009, Intel agreed to pay AMD $1.25bn and renew a five-year patent cross-licensing agreement as part of a deal to settle all outstanding legal disputes between them. Guinness World Record achievement On August 31, 2011, in Austin, Texas, AMD achieved a Guinness World Record for the "Highest frequency of a computer processor": 8.429 GHz. The company ran an 8-core FX-8150 processor with only one active module (two cores), and cooled with liquid helium. The previous record was 8.308 GHz, with an Intel Celeron 352 (one core). On November 1, 2011, geek.com reported that Andre Yang, an overclocker from Taiwan, used an FX-8150 to set another record: 8.461 GHz. On November 19, 2012, Andre Yang used an FX-8350 to set another record: 8.794 GHz. Acquisitions, mergers and investments Corporate social responsibility In its 2012 report on progress relating to conflict minerals, the Enough Project rated AMD the fifth most progressive of 24 consumer electronics companies. Other initiatives 50x15, digital inclusion, with targeted 50% of world population to be connected through Internet via affordable computers by the year of 2015. The Green Grid, founded by AMD together with other founders, such as IBM, Sun and Microsoft, to seek lower power consumption for grids.

Aon PLC () is a British-American professional services and management consulting firm that offers a range of risk-mitigation products. The firm also provides data and analytics services, strategy consulting through Aon Inpoint and investment banking advisory through Aon Securities. Aon has approximately 50,000 employees across 120 countries. Founded in Chicago by Patrick Ryan, Aon was created in 1982 when the Ryan Insurance Group merged with the Combined Insurance Company of America. In 1987, that company was renamed Aon from aon, a Gaelic word meaning "one". The company is globally headquartered in London with its North America operations based in Chicago at the Aon Center. Aon is listed on the New York Stock Exchange under AON with a market cap of $65 billion in April 2023. History W. Clement Stone's mother bought a small Detroit insurance agency, and in 1918 brought her son into the business. Mr. Stone sold low-cost, low-benefit accident insurance, underwriting and issuing policies on-site. The next year he founded his own agency, the Combined Registry Co. As the Great Depression began, Stone reduced his workforce and improved training. Forced by his son's respiratory illness to winter in the South, Stone moved to Arkansas and Texas. In 1939 he bought American Casualty Insurance Co. of Dallas, Texas. It was consolidated with other purchases as the Combined Insurance Co. of America in 1947. The company continued through the 1950s and 1960s, continuing to sell health and accident policies. In the 1970s, Combined expanded overseas despite being hit hard by the recession. In 1982, after 10 years of stagnation under Clement Stone Jr., the elder Stone, then 79, resumed control until the completion of a merger with Ryan Insurance Co. allowed him to transfer control to Patrick Ryan. Ryan, the son of a Ford dealer in Wisconsin and a graduate of Northwestern University, had started his company as an auto credit insurer in 1964. In 1976, the company bought the insurance brokerage units of the Esmark conglomerate. Ryan focused on insurance brokering and added more upscale insurance products. He also trimmed staff and took other cost-cutting measures, and in 1987 he changed Combined's name to Aon. In 1992, he bought Dutch insurance broker Hudig-Langeveldt. In 1995, the company sold its remaining direct life insurance holdings to General Electric to focus on consulting. Aon built a global presence through purchases. In 1997, it bought The Minet Group, as well as insurance brokerage Alexander & Alexander Services, Inc. in a deal that made Aon (temporarily) the largest insurance broker worldwide. The firm made no US buys in 1998, but doubled its employee base with purchases including Spain's largest retail insurance broker, Gil y Carvajal, and the formation of Aon Korea. Responding to industry demands, Aon announced its new fee disclosure policy in 1999, and the company reorganised to focus on buying personal line insurance firms and to integrate its acquisitions. That year it bought Nikols Sedgwick Group, an Italian insurance firm, and formed RiskAttack (with Zurich US), a risk analysis and financial management concern aimed at technology companies. The cost of integrating its numerous purchases, however, hammered profits in 1999. Despite its troubles, in 2000 Aon bought Reliance Group's accident and health insurance business, as well as Actuarial Sciences Associates, a compensation and employee benefits consulting company. Later in that year, however, the company decided to cut 6% of its workforce as part of a restructuring effort. In 2003, the company saw revenues increase primarily because of rate hikes in the insurance industry. Also that year, Endurance Specialty, a Bermuda-based underwriting operation that Aon helped to establish in November 2001 along with other investors, went public. The next year Aon sold most of its holdings in Endurance. In the late 2007, Aon announced the divestiture of its underwriting business. With this move, the firm sold off its two major underwriting subsidiaries: Combined Insurance Company of America (acquired by ACE Limited for $2.4 billion) and Sterling Life Insurance Company (purchased by Munich Re Group for $352 million). The low margin and capital-intensive nature of the underwriting industry was the primary reason for the firm's decision to divest. This growth strategy manifested in November 2008 when Aon announced it had acquired reinsurance intermediary and capital advisor Benfield Group Limited for $1.75 billion. The acquisition amplified the firm's broking capabilities, positioning Aon one of the largest players in the reinsurance brokerage industry. In 2010, Aon made its most significant acquisition to date with the purchase of Hewitt Associates for $4.9 billion. Aside from drastically boosting Aon's human resources consulting capacity and entering the firm into the business process outsourcing industry, the move added 23,000 colleagues and more than $3 billion in revenue. In January 2012, Aon announced that its headquarters would be moved to London, although North American operations and jobs remained in Chicago. On 10 February 2017, Aon announced that it was selling its employee benefits outsourcing business to private equity firm The Blackstone Group for US$4.8 billion (£3.8 billion). In February 2020, Aon named Eric Andersen as president of Aon after co-president Michael O'Connor departed the company to pursue new opportunities. He will be reporting to Greg Case, the firm's CEO. In June 2020, Aon announced it was planning to repay the temporary 20% pay cut from 70% of employees that was published in a statement in April 2020 regarding the COVID-19 pandemic. On 30 June 2020, Aon announced it would repay staff in full, plus 5% of the withheld amount. In June 2020, Willis Towers Watson called its shareholders to two meetings to discuss its acquisition with Aon for August 26, 2020. It was revealed that the US Department of Justice has requested more information on the deal under antitrust rules. September 11 attacks Aon's New York offices were on the 92nd and 98th–105th floors of the South Tower of the World Trade Center at the time of the September 11 attacks. When the North Tower was struck by American Airlines Flight 11 at 8:46 a.m., an evacuation of Aon's offices was quickly initiated by executive Eric Eisenberg, and 924 of the estimated 1,100 Aon employees present at the time managed to get below the 77th floor before United Airlines Flight 175 crashed between Floors 77 and 85 at 9:03 a.m. Many, however, did not manage to get beneath in the 17 minutes they had between the two impacts. As a result, 176 employees of Aon were killed in the crash or died in the eventual collapse of the tower or from smoke inhalation. At 9:59 a.m., the tower finally collapsed, killing any survivors still within, including Eisenberg and Kevin Cosgrove. Spitzer investigation In 2004–2005, Aon, along with other brokers including Marsh & McLennan and Willis, fell under regulatory investigation under New York Attorney General Eliot Spitzer and other state attorneys general. At issue was the practice of insurance companies' payments to brokers (known as contingent commissions). The payments were thought to bring a conflict of interest, swaying broker decisions on behalf of carriers, rather than customers. In the spring of 2005, without acknowledging any wrongdoing, Aon agreed to a $190 million settlement, payable over 30 months. UK regulatory breach In January 2009, Aon was fined £5.69 million in the UK by the Financial Services Authority, who stated that the fine related to the company's inadequate bribery and corruption controls, claiming that between 14 January 2005 and 30 September 2007 Aon had failed to properly assess the risks involved in its dealings with overseas firms and individuals. The Authority did not find that any money had actually made its way to illegal organisations. Aon qualified for a 30% discount on the fine as a result of its cooperation with the investigation. Aon said its conduct was not deliberate, adding it had since "significantly strengthened and enhanced its controls around the usage of third parties". US Foreign Corrupt Practices Act violations In December 2011, Aon Corporation paid a $16.26 million penalty to the U.S. Securities and Exchange Commission and the U.S. Department of Justice for violations of the US Foreign Corrupt Practices Act. According to the Securities and Exchange Commission, Aon's subsidiaries made improper payments of over $3.6 million to government officials and third-party facilitators in Costa Rica, Egypt, Vietnam, Indonesia, the United Arab Emirates, Myanmar and Bangladesh, between 1983 and 2007, to obtain and retain insurance contracts. Major acquisitions On 5 January 2007, Aon announced that its Aon Affinity group had acquired the WedSafe Wedding Insurance program. On 22 August 2008, Aon announced that it had acquired London-based Benfield Group. The acquiring price was US$1.75 billion or £935 million, with US$170 million of debt. On 5 March 2010, Hewitt Associates announced that it acquired Senior Educators Ltd. The acquisition offers companies a new way to address retiree medical insurance commitments. On 12 July 2010, Aon announced that it had agreed to buy Lincolnshire, Illinois-based Hewitt Associates for $4.9 billion in cash and stock. On 7 April 2011, Aon announced that it had acquired Johannesburg, South Africa-based Glenrand MIB. Financial terms were not disclosed. On 19 July 2011, Aon announced that it bought Westfield Financial Corp., the owner of insurance-industry consulting firm Ward Financial Group, from Ohio Farmers Insurance Co. Financial terms were not disclosed. On 22 October 2012, Aon announced that it agreed to buy OmniPoint, Inc, a Workday consulting firm. Financial terms were not disclosed. On 16 June 2014, Aon announced that it agreed to buy National Flood Services, Inc., a large processor of flood insurance, from Stoneriver Group, L.P. On 31 October 2016, Aon's Aon Risk Solutions completed acquisition of Stroz Friedberg LLC, a specialised risk management firm focusing on cybersecurity. On 14 November 2016, Aon acquired CoCubes an online Indian Assessment firm, facilitating hiring of entry-level engineering graduates. On 10 February 2017, Aon plc agreed to sell its human resources outsourcing platform for US$4.8 billion (£3.8 billion) to Blackstone Group L.P. (BX.N), creating a new company called Alight Solutions. In September 2017, Aon announced its intent to purchase real estate investment management firm The Townsend Group from Colony NorthStar for $475 million, expanding Aon's property investment management portfolio. On 9 March 2020, Aon announced its merger with Willis Towers Watson for nearly $30 billion in an all-stock deal that creates the world's largest insurance broker. As of 21 May 2020, Willis board was under probe over merger agreement with Aon. The deal was called off in July 2021. Operations Manchester United On 3 June 2009, it was reported that Aon had signed a four-year shirt sponsorship deal with English football giant Manchester United. On 1 June 2010, Aon replaced American insurance company AIG as the principal sponsor of the club. The Aon logo was prominently displayed on the front of the club's shirts until the 2014/2015 season when Chevrolet replaced them. The deal was said to be worth £80 million over four years, replacing United's deal with AIG as the most lucrative shirt deal in history at the time. In April 2013, Aon signed a new eight-year deal with Manchester United to rename their training ground as the Aon Training Complex and sponsor the club's training kits, reportedly worth £180 million to the club.

Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography, electrophoresis or field flow fractionation. Then qualitative and quantitative analysis can be performed, often with the same instrument and may use light interaction, heat interaction, electric fields or magnetic fields. Often the same instrument can separate, identify and quantify an analyte. Analytical chemistry is also focused on improvements in experimental design, chemometrics, and the creation of new measurement tools. Analytical chemistry has broad applications to medicine, science, and engineering. History Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized organic analysis based on the specific reactions of functional groups. The first instrumental analysis was flame emissive spectrometry developed by Robert Bunsen and Gustav Kirchhoff who discovered rubidium (Rb) and caesium (Cs) in 1860. Most of the major developments in analytical chemistry took place after 1900. During this period, instrumental analysis became progressively dominant in the field. In particular, many of the basic spectroscopic and spectrometric techniques were discovered in the early 20th century and refined in the late 20th century. The separation sciences follow a similar time line of development and also became increasingly transformed into high performance instruments. In the 1970s many of these techniques began to be used together as hybrid techniques to achieve a complete characterization of samples. Starting in the 1970s, analytical chemistry became progressively more inclusive of biological questions (bioanalytical chemistry), whereas it had previously been largely focused on inorganic or small organic molecules. Lasers have been increasingly used as probes and even to initiate and influence a wide variety of reactions. The late 20th century also saw an expansion of the application of analytical chemistry from somewhat academic chemical questions to forensic, environmental, industrial and medical questions, such as in histology. Modern analytical chemistry is dominated by instrumental analysis. Many analytical chemists focus on a single type of instrument. Academics tend to either focus on new applications and discoveries or on new methods of analysis. The discovery of a chemical present in blood that increases the risk of cancer would be a discovery that an analytical chemist might be involved in. An effort to develop a new method might involve the use of a tunable laser to increase the specificity and sensitivity of a spectrometric method. Many methods, once developed, are kept purposely static so that data can be compared over long periods of time. This is particularly true in industrial quality assurance (QA), forensic and environmental applications. Analytical chemistry plays an increasingly important role in the pharmaceutical industry where, aside from QA, it is used in the discovery of new drug candidates and in clinical applications where understanding the interactions between the drug and the patient are critical. Classical methods Although modern analytical chemistry is dominated by sophisticated instrumentation, the roots of analytical chemistry and some of the principles used in modern instruments are from traditional techniques, many of which are still used today. These techniques also tend to form the backbone of most undergraduate analytical chemistry educational labs. Qualitative analysis Qualitative analysis determines the presence or absence of a particular compound, but not the mass or concentration. By definition, qualitative analyses do not measure quantity. Chemical tests There are numerous qualitative chemical tests, for example, the acid test for gold and the Kastle-Meyer test for the presence of blood. Flame test Inorganic qualitative analysis generally refers to a systematic scheme to confirm the presence of certain aqueous ions or elements by performing a series of reactions that eliminate a range of possibilities and then confirm suspected ions with a confirming test. Sometimes small carbon-containing ions are included in such schemes. With modern instrumentation, these tests are rarely used but can be useful for educational purposes and in fieldwork or other situations where access to state-of-the-art instruments is not available or expedient. Quantitative analysis Quantitative analysis is the measurement of the quantities of particular chemical constituents present in a substance. Quantities can be measured by mass (gravimetric analysis) or volume (volumetric analysis). Gravimetric analysis The gravimetric analysis involves determining the amount of material present by weighing the sample before and/or after some transformation. A common example used in undergraduate education is the determination of the amount of water in a hydrate by heating the sample to remove the water such that the difference in weight is due to the loss of water. Volumetric analysis Titration involves the gradual addition of a measurable reactant to an exact volume of a solution being analyzed until some equivalence point is reached. Titrating accurately to either the half-equivalence point or the endpoint of a titration allows the chemist to determine the amount of moles used, which can then be used to determine a concentration or composition of the titrant. Most familiar to those who have taken chemistry during secondary education is the acid-base titration involving a color-changing indicator, such as phenolphthalein. There are many other types of titrations, for example, potentiometric titrations or precipitation titrations. Chemists might also create titration curves in order by systematically testing the pH every drop in order to understand different properties of the titrant. Instrumental methods Spectroscopy Spectroscopy measures the interaction of the molecules with electromagnetic radiation. Spectroscopy consists of many different applications such as atomic absorption spectroscopy, atomic emission spectroscopy, ultraviolet-visible spectroscopy, X-ray spectroscopy, fluorescence spectroscopy, infrared spectroscopy, Raman spectroscopy, dual polarization interferometry, nuclear magnetic resonance spectroscopy, photoemission spectroscopy, Mössbauer spectroscopy and so on. Mass spectrometry Mass spectrometry measures mass-to-charge ratio of molecules using electric and magnetic fields. There are several ionization methods: electron ionization, chemical ionization, electrospray ionization, fast atom bombardment, matrix assisted laser desorption/ionization, and others. Also, mass spectrometry is categorized by approaches of mass analyzers: magnetic-sector, quadrupole mass analyzer, quadrupole ion trap, time-of-flight, Fourier transform ion cyclotron resonance, and so on. Electrochemical analysis Electroanalytical methods measure the potential (volts) and/or current (amps) in an electrochemical cell containing the analyte. These methods can be categorized according to which aspects of the cell are controlled and which are measured. The four main categories are potentiometry (the difference in electrode potentials is measured), coulometry (the transferred charge is measured over time), amperometry (the cell's current is measured over time), and voltammetry (the cell's current is measured while actively altering the cell's potential). Thermal analysis Calorimetry and thermogravimetric analysis measure the interaction of a material and heat. Separation Separation processes are used to decrease the complexity of material mixtures. Chromatography, electrophoresis and field flow fractionation are representative of this field. Hybrid techniques Combinations of the above techniques produce a "hybrid" or "hyphenated" technique. Several examples are in popular use today and new hybrid techniques are under development. For example, gas chromatography-mass spectrometry, gas chromatography-infrared spectroscopy, liquid chromatography-mass spectrometry, liquid chromatography-NMR spectroscopy, liquid chromatography-infrared spectroscopy, and capillary electrophoresis-mass spectrometry. Hyphenated separation techniques refer to a combination of two (or more) techniques to detect and separate chemicals from solutions. Most often the other technique is some form of chromatography. Hyphenated techniques are widely used in chemistry and biochemistry. A slash is sometimes used instead of hyphen, especially if the name of one of the methods contains a hyphen itself. Microscopy The visualization of single molecules, single cells, biological tissues, and nanomaterials is an important and attractive approach in analytical science. Also, hybridization with other traditional analytical tools is revolutionizing analytical science. Microscopy can be categorized into three different fields: optical microscopy, electron microscopy, and scanning probe microscopy. Recently, this field is rapidly progressing because of the rapid development of the computer and camera industries. Lab-on-a-chip Devices that integrate (multiple) laboratory functions on a single chip of only millimeters to a few square centimeters in size and that are capable of handling extremely small fluid volumes down to less than picoliters. Errors Error can be defined as numerical difference between observed value and true value. The experimental error can be divided into two types, systematic error and random error. Systematic error results from a flaw in equipment or the design of an experiment while random error results from uncontrolled or uncontrollable variables in the experiment. In error the true value and observed value in chemical analysis can be related with each other by the equation where is the absolute error. is the true value. is the observed value. An error of a measurement is an inverse measure of accurate measurement, i.e. smaller the error greater the accuracy of the measurement. Errors can be expressed relatively. Given the relative error(): The percent error can also be calculated: If we want to use these values in a function, we may also want to calculate the error of the function. Let be a function with variables. Therefore, the propagation of uncertainty must be calculated in order to know the error in : Standards Standard curve A general method for analysis of concentration involves the creation of a calibration curve. This allows for the determination of the amount of a chemical in a material by comparing the results of an unknown sample to those of a series of known standards. If the concentration of element or compound in a sample is too high for the detection range of the technique, it can simply be diluted in a pure solvent. If the amount in the sample is below an instrument's range of measurement, the method of addition can be used. In this method, a known quantity of the element or compound under study is added, and the difference between the concentration added and the concentration observed is the amount actually in the sample. Internal standards Sometimes an internal standard is added at a known concentration directly to an analytical sample to aid in quantitation. The amount of analyte present is then determined relative to the internal standard as a calibrant. An ideal internal standard is an isotopically enriched analyte which gives rise to the method of isotope dilution. Standard addition The method of standard addition is used in instrumental analysis to determine the concentration of a substance (analyte) in an unknown sample by comparison to a set of samples of known concentration, similar to using a calibration curve. Standard addition can be applied to most analytical techniques and is used instead of a calibration curve to solve the matrix effect problem. Signals and noise One of the most important components of analytical chemistry is maximizing the desired signal while minimizing the associated noise. The analytical figure of merit is known as the signal-to-noise ratio (S/N or SNR). Noise can arise from environmental factors as well as from fundamental physical processes. Thermal noise Thermal noise results from the motion of charge carriers (usually electrons) in an electrical circuit generated by their thermal motion. Thermal noise is white noise meaning that the power spectral density is constant throughout the frequency spectrum. The root mean square value of the thermal noise in a resistor is given by where kB is Boltzmann's constant, T is the temperature, R is the resistance, and is the bandwidth of the frequency . Shot noise Shot noise is a type of electronic noise that occurs when the finite number of particles (such as electrons in an electronic circuit or photons in an optical device) is small enough to give rise to statistical fluctuations in a signal. Shot noise is a Poisson process, and the charge carriers that make up the current follow a Poisson distribution. The root mean square current fluctuation is given by where e is the elementary charge and I is the average current. Shot noise is white noise. Flicker noise Flicker noise is electronic noise with a 1/ƒ frequency spectrum; as f increases, the noise decreases. Flicker noise arises from a variety of sources, such as impurities in a conductive channel, generation, and recombination noise in a transistor due to base current, and so on. This noise can be avoided by modulation of the signal at a higher frequency, for example, through the use of a lock-in amplifier. Environmental noise Environmental noise arises from the surroundings of the analytical instrument. Sources of electromagnetic noise are power lines, radio and television stations, wireless devices, compact fluorescent lamps and electric motors. Many of these noise sources are narrow bandwidth and, therefore, can be avoided. Temperature and vibration isolation may be required for some instruments. Noise reduction Noise reduction can be accomplished either in computer hardware or software. Examples of hardware noise reduction are the use of shielded cable, analog filtering, and signal modulation. Examples of software noise reduction are digital filtering, ensemble average, boxcar average, and correlation methods. Applications Analytical chemistry has applications including in forensic science, bioanalysis, clinical analysis, environmental analysis, and materials analysis. Analytical chemistry research is largely driven by performance (sensitivity, detection limit, selectivity, robustness, dynamic range, linear range, accuracy, precision, and speed), and cost (purchase, operation, training, time, and space). Among the main branches of contemporary analytical atomic spectrometry, the most widespread and universal are optical and mass spectrometry. In the direct elemental analysis of solid samples, the new leaders are laser-induced breakdown and laser ablation mass spectrometry, and the related techniques with transfer of the laser ablation products into inductively coupled plasma. Advances in design of diode lasers and optical parametric oscillators promote developments in fluorescence and ionization spectrometry and also in absorption techniques where uses of optical cavities for increased effective absorption pathlength are expected to expand. The use of plasma- and laser-based methods is increasing. An interest towards absolute (standardless) analysis has revived, particularly in emission spectrometry. Great effort is being put into shrinking the analysis techniques to chip size. Although there are few examples of such systems competitive with traditional analysis techniques, potential advantages include size/portability, speed, and cost. (micro total analysis system (µTAS) or lab-on-a-chip). Microscale chemistry reduces the amounts of chemicals used. Many developments improve the analysis of biological systems. Examples of rapidly expanding fields in this area are genomics, DNA sequencing and related research in genetic fingerprinting and DNA microarray; proteomics, the analysis of protein concentrations and modifications, especially in response to various stressors, at various developmental stages, or in various parts of the body, metabolomics, which deals with metabolites; transcriptomics, including mRNA and associated fields; lipidomics - lipids and its associated fields; peptidomics - peptides and its associated fields; and metallomics, dealing with metal concentrations and especially with their binding to proteins and other molecules. Analytical chemistry has played a critical role in the understanding of basic science to a variety of practical applications, such as biomedical applications, environmental monitoring, quality control of industrial manufacturing, forensic science, and so on. The recent developments in computer automation and information technologies have extended analytical chemistry into a number of new biological fields. For example, automated DNA sequencing machines were the basis for completing human genome projects leading to the birth of genomics. Protein identification and peptide sequencing by mass spectrometry opened a new field of proteomics. In addition to automating specific processes, there is effort to automate larger sections of lab testing, such as in companies like Emerald Cloud Lab and Transcriptic. Analytical chemistry has been an indispensable area in the development of nanotechnology. Surface characterization instruments, electron microscopes and scanning probe microscopes enable scientists to visualize atomic structures with chemical characterizations.

A cappella (, , ; ) music is a performance by a singer or a singing group without instrumental accompaniment, or a piece intended to be performed in this fashion. The term a cappella was originally intended to differentiate between Renaissance polyphony and Baroque concertato musical styles. In the 19th century, a renewed interest in Renaissance polyphony, coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists, led to the term coming to mean unaccompanied vocal music. The term is also used, rarely, as a synonym for alla breve. Early history A cappella could be as old as humanity itself. Research suggests that singing and vocables may have been what early humans used to communicate before the invention of language. The earliest piece of sheet music is thought to have originated from times as early as 2000 BC, while the earliest that has survived in its entirety is from the first century AD: a piece from Greece called the Seikilos epitaph. Religious origins A cappella music was originally used in religious music, especially church music as well as anasheed and zemirot. Gregorian chant is an example of a cappella singing, as is the majority of secular vocal music from the Renaissance. The madrigal, up until its development in the early Baroque into an instrumentally accompanied form, is also usually in a cappella form. The Psalms note that some early songs were accompanied by string instruments, though Jewish and Early Christian music was largely a cappella; the use of instruments has subsequently increased within both of these religions as well as in Islam. Christian The polyphony of Christian a cappella music began to develop in Europe around the late 15th century AD, with compositions by Josquin des Prez. The early a cappella polyphonies may have had an accompanying instrument, although this instrument would merely double the singers' parts and was not independent. By the 16th century, a cappella polyphony had further developed, but gradually, the cantata began to take the place of a cappella forms. Sixteenth-century a cappella polyphony, nonetheless, continued to influence church composers throughout this period and to the present day. Recent evidence has shown that some of the early pieces by Palestrina, such as those written for the Sistine Chapel, were intended to be accompanied by an organ "doubling" some or all of the voices. Such is seen in the life of Palestrina becoming a major influence on Bach, most notably in the Mass in B Minor. Other composers that utilized the a cappella style, if only for the occasional piece, were Claudio Monteverdi and his masterpiece, Lagrime d'amante al sepolcro dell'amata (A lover's tears at his beloved's grave), which was composed in 1610, and Andrea Gabrieli when upon his death many choral pieces were discovered, one of which was in the unaccompanied style. Learning from the preceding two composers, Heinrich Schütz utilized the a cappella style in numerous pieces, chief among these were the pieces in the oratorio style, which were traditionally performed during the Easter week and dealt with the religious subject matter of that week, such as Christ's suffering and the Passion. Five of Schutz's Historien were Easter pieces, and of these the latter three, which dealt with the passion from three different viewpoints, those of Matthew, Luke and John, were all done a cappella style. This was a near requirement for this type of piece, and the parts of the crowd were sung while the solo parts which were the quoted parts from either Christ or the authors were performed in a plainchant. Byzantine Rite In the Byzantine Rite of the Eastern Orthodox Church and the Eastern Catholic Churches, the music performed in the liturgies is exclusively sung without instrumental accompaniment. Bishop Kallistos Ware says, "The service is sung, even though there may be no choir... In the Orthodox Church today, as in the early Church, singing is unaccompanied and instrumental music is not found." This a cappella behavior arises from strict interpretation of Psalm 150, which states, Let every thing that hath breath praise the Lord. Praise ye the Lord. In keeping with this philosophy, early Russian musika which started appearing in the late 17th century, in what was known as khorovïye kontsertï (choral concertos) made a cappella adaptations of Venetian-styled pieces, such as the treatise, Grammatika musikiyskaya (1675), by Nikolai Diletsky. Divine Liturgies and Western Rite Masses composed by famous composers such as Peter Tchaikovsky, Sergei Rachmaninoff, Alexander Arkhangelsky, and Mykola Leontovych are fine examples of this. Opposition to instruments in worship Present-day Christian religious bodies known for conducting their worship services without musical accompaniment include many Oriental Orthodox Churches (such as the Coptic Orthodox Church), many Anabaptist communities (including Old Order Anabaptist groups—such as the Amish, Old German Baptist Brethren, Old Order Mennonites, as well as Conservative Anabaptist groups—such as the Dunkard Brethren Church and Conservative Mennonites), some Presbyterian churches devoted to the regulative principle of worship, Old Regular Baptists, Primitive Baptists, Plymouth Brethren, Churches of Christ, Church of God (Guthrie, Oklahoma), the Reformed Free Methodists, Doukhobors, and the Byzantine Rite of Eastern Christianity. Certain high church services and other musical events in liturgical churches (such as the Roman Catholic Mass and the Lutheran Divine Service) may be a cappella, a practice remaining from apostolic times. Many Mennonites also conduct some or all of their services without instruments. Sacred Harp, a type of folk music, is an a cappella style of religious singing with shape notes, usually sung at singing conventions. Opponents of musical instruments in the Christian worship believe that such opposition is supported by the Christian scriptures and Church history. The scriptures typically referenced are Matthew 26:30; Acts 16:25; Romans 15:9; 1 Corinthians 14:15; Ephesians 5:19; Colossians 3:16; Hebrews 2:12, 13:15 and James 5:13, which show examples and exhortations for Christians to sing. There is no reference to instrumental music in early church worship in the New Testament, or in the worship of churches for the first six centuries. Several reasons have been posited throughout church history for the absence of instrumental music in church worship. Christians who believe in a cappella music today believe that in the Israelite worship assembly during Temple worship only the Priests of Levi sang, played, and offered animal sacrifices, whereas in the church era, all Christians are commanded to sing praises to God. They believe that if God wanted instrumental music in New Testament worship, He would have commanded not just singing, but singing and playing like he did in the Hebrew scriptures. Instruments have divided Christendom since their introduction into worship. They were considered a Roman Catholic innovation, not widely practiced until the 18th century, and were opposed vigorously in worship by a number of Protestant Reformers, including Martin Luther (1483–1546), Ulrich Zwingli, John Calvin (1509–1564) and John Wesley (1703–1791). Alexander Campbell referred to the use of an instrument in worship as "a cow bell in a concert". In Sir Walter Scott's The Heart of Midlothian, the heroine, Jeanie Deans, a Scottish Presbyterian, writes to her father about the church situation she has found in England (bold added): The folk here are civil, and, like the barbarians unto the holy apostle, have shown me much kindness; and there are a sort of chosen people in the land, for they have some kirks without organs that are like ours, and are called meeting-houses, where the minister preaches without a gown. Acceptance of instruments in worship Those who do not adhere to the regulative principle of interpreting Christian scripture, believe that limiting praise to the unaccompanied chant of the early church is not commanded in scripture, and that churches in any age are free to offer their songs with or without musical instruments. Those who subscribe to this interpretation believe that since the Christian scriptures never counter instrumental language with any negative judgment on instruments, opposition to instruments instead comes from an interpretation of history. There is no written opposition to musical instruments in any setting in the first century and a half of Christian churches (33–180 AD). The use of instruments for Christian worship during this period is also undocumented. Toward the end of the 2nd century, Christians began condemning the instruments themselves. Those who oppose instruments today believe these Church Fathers had a better understanding of God's desire for the church, but there are significant differences between the teachings of these Church Fathers and Christian opposition to instruments today. Modern Christians typically believe it is acceptable to play instruments or to attend weddings, funerals, banquets, etc., where instruments are heard playing religious music. The Church Fathers made no exceptions. Since the New Testament never condemns instruments themselves, much less in any of these settings, it is believed that "the church Fathers go beyond the New Testament in pronouncing a negative judgment on musical instruments." Written opposition to instruments in worship began near the turn of the 5th century. Modern opponents of instruments typically do not make the same assessment of instruments as these writers, who argued that God had allowed David the "evil" of using musical instruments in praise. While the Old Testament teaches that God specifically asked for musical instruments, modern concern is for worship based on the New Testament. Since "a cappella" singing brought a new polyphony (more than one note at a time) with instrumental accompaniment, it is not surprising that Protestant reformers who opposed the instruments (such as Calvin and Zwingli) also opposed the polyphony. While Zwingli was destroying organs in Switzerland – Luther called him a fanatic – the Church of England was burning books of polyphony. Some Holiness Churches such as the Free Methodist Church opposed the use of musical instruments in church worship until the mid-20th century. The Free Methodist Church allowed for local church decision on the use of either an organ or piano in the 1943 Conference before lifting the ban entirely in 1955. The Reformed Free Methodist Church and Evangelical Wesleyan Church were formed as a result of a schism with the Free Methodist Church, with the former retaining a cappella worship and the latter retaining the rule limiting the number of instruments in the church to the piano and organ. Jewish While worship in the Temple in Jerusalem included musical instruments, traditional Jewish religious services in the Synagogue, both before and after the last destruction of the Temple, did not include musical instruments given the practice of scriptural cantillation. The use of musical instruments is traditionally forbidden on the Sabbath out of concern that players would be tempted to repair (or tune) their instruments, which is forbidden on those days. (This prohibition has been relaxed in many Reform and some Conservative congregations.) Similarly, when Jewish families and larger groups sing traditional Sabbath songs known as zemirot outside the context of formal religious services, they usually do so a cappella, and Bar and Bat Mitzvah celebrations on the Sabbath sometimes feature entertainment by a cappella ensembles. During the Three Weeks musical instruments are prohibited. Many Jews consider a portion of the 49-day period of the counting of the omer between Passover and Shavuot to be a time of semi-mourning and instrumental music is not allowed during that time. This has led to a tradition of a cappella singing sometimes known as sefirah music. The popularization of the Jewish chant may be found in the writings of the Jewish philosopher Philo, born 20 BC. Weaving together Jewish and Greek thought, Philo promoted praise without instruments, and taught that "silent singing" (without even vocal chords) was better still. This view parted with the Jewish scriptures, where Israel offered praise with instruments by God's own command The shofar is the only temple instrument still being used today in the synagogue, and it is only used from Rosh Chodesh Elul through the end of Yom Kippur. The shofar is used by itself, without any vocal accompaniment, and is limited to a very strictly defined set of sounds and specific places in the synagogue service. However, silver trumpets, as described in Numbers 10:1-18, have been made in recent years and used in prayer services at the Western Wall. In the United States Peter Christian Lutkin, dean of the Northwestern University School of Music, helped popularize a cappella music in the United States by founding the Northwestern A Cappella Choir in 1906. The A Cappella Choir was "the first permanent organization of its kind in America." An a cappella tradition was begun in 1911 by F. Melius Christiansen, a music faculty member at St. Olaf College in Northfield, Minnesota. The St. Olaf College Choir was established as an outgrowth of the local St. John's Lutheran Church, where Christiansen was organist and the choir was composed, at least partially, of students from the nearby St. Olaf campus. The success of the ensemble was emulated by other regional conductors, and a tradition of a cappella choral music was born in the region at colleges like Concordia College (Moorhead, Minnesota), Augustana College (Rock Island, Illinois), Waldorf University (Forest City, Iowa), Luther College (Decorah, Iowa), Gustavus Adolphus College (St. Peter, Minnesota), Augustana College (Sioux Falls, South Dakota), and Augsburg University (Minneapolis, Minnesota). The choirs typically range from 40 to 80 singers and are recognized for their efforts to perfect blend, intonation, phrasing and pitch in a large choral setting. Movements in modern a cappella over the past century include barbershop and doo wop. The Barbershop Harmony Society, Sweet Adelines International, and Harmony Inc. host educational events including Harmony University, Directors University, and the International Educational Symposium, and international contests and conventions, recognizing international champion choruses and quartets. Many a cappella groups can be found in high schools and colleges. There are amateur Barbershop Harmony Society and professional groups that sing a cappella exclusively. Although a cappella is technically defined as singing without instrumental accompaniment, some groups use their voices to emulate instruments; others are more traditional and focus on harmonizing. A cappella styles range from gospel music to contemporary to barbershop quartets and choruses. The Contemporary A Cappella Society (CASA) is a membership option for former students, whose funds support hosted competitions and events. A cappella music was popularized between the late 2000s and the early to mid-2010s with media hits such as the 2009–2014 TV show The Sing-Off and the musical comedy film series Pitch Perfect. Recording artists In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In on a Wing and a Prayer". In the 1950s, several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. Frank Zappa loved doo wop and a cappella, so Zappa released The Persuasions' first album from his label in 1970. Judy Collins recorded "Amazing Grace" a cappella. In 1983, an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys, Boyz II Men, and *NSYNC. Contemporary a cappella includes many vocal groups and bands who add vocal percussion or beatboxing to create a pop/rock/gospel sound, in some cases very similar to bands with instruments. Examples of such professional groups include Straight No Chaser, Pentatonix, The House Jacks, Rockapella, Mosaic, Home Free and M-pact. There also remains a strong a cappella presence within Christian music, as some denominations purposefully do not use instruments during worship. Examples of such groups are Take 6, Glad and Acappella. Arrangements of popular music for small a cappella ensembles typically include one voice singing the lead melody, one singing a rhythmic bass line, and the remaining voices contributing chordal or polyphonic accompaniment. A cappella can also describe the isolated vocal track(s) from a multitrack recording that originally included instrumentation. These vocal tracks may be remixed or put onto vinyl records for DJs, or released to the public so that fans can remix them. One such example is the a cappella release of Jay-Z's Black Album, which Danger Mouse mixed with the Beatles' White Album to create The Grey Album. On their 1966 album titled Album, Peter, Paul and Mary included the song "Norman Normal". All the sounds on that song, both vocals and instruments, were created by Paul's voice, with no actual instruments used. In 2013, an artist by the name Smooth McGroove rose to prominence with his style of a cappella music. He is best known for his a cappella covers of video game music tracks on YouTube. in 2015, an a cappella version of Jerusalem by multi-instrumentalist Jacob Collier was selected for Beats by Dre "The Game Starts Here" for the England Rugby World Cup campaign. Musical theatre A cappella has been used as the sole orchestration for original works of musical theatre that have had commercial runs Off-Broadway (theatres in New York City with 99 to 500 seats) only four times. The first was Avenue X which opened on 28 January 1994 and ran for 77 performances. It was produced by Playwrights Horizons with book by John Jiler, music and lyrics by Ray Leslee. The musical style of the show's score was primarily Doo-Wop as the plot revolved around Doo-Wop group singers of the 1960s. In 2001, The Kinsey Sicks, produced and starred in the critically acclaimed off-Broadway hit, "DRAGAPELLA! Starring the Kinsey Sicks" at New York's legendary Studio 54. That production received a nomination for a Lucille Lortel award as Best Musical and a Drama Desk nomination for Best Lyrics. It was directed by Glenn Casale with original music and lyrics by Ben Schatz. The a cappella musical Perfect Harmony, a comedy about two high school a cappella groups vying to win the National championship, made its Off Broadway debut at Theatre Row's Acorn Theatre on 42nd Street in New York City in October 2010 after a successful out-of-town run at the Stoneham Theatre, in Stoneham, Massachusetts. Perfect Harmony features the hit music of The Jackson 5, Pat Benatar, Billy Idol, Marvin Gaye, Scandal, Tiffany, The Romantics, The Pretenders, The Temptations, The Contours, The Commodores, Tommy James & the Shondells and The Partridge Family, and has been compared to a cross between Altar Boyz and The 25th Annual Putnam County Spelling Bee. The fourth a cappella musical to appear Off-Broadway, In Transit, premiered 5 October 2010 and was produced by Primary Stages with book, music, and lyrics by Kristen Anderson-Lopez, James-Allen Ford, Russ Kaplan, and Sara Wordsworth. Set primarily in the New York City subway system its score features an eclectic mix of musical genres (including jazz, hip hop, Latin, rock, and country). In Transit incorporates vocal beat boxing into its contemporary a cappella arrangements through the use of a subway beat boxer character. Beat boxer and actor Chesney Snow performed this role for the 2010 Primary Stages production. According to the show's website, it is scheduled to reopen for an open-ended commercial run in the Fall of 2011. In 2011, the production received four Lucille Lortel Award nominations including Outstanding Musical, Outer Critics Circle and Drama League nominations, as well as five Drama Desk nominations including Outstanding Musical and won for Outstanding Ensemble Performance. In December 2016, In Transit became the first a cappella musical on Broadway. Barbershop style Barbershop music is one of several uniquely American art forms. The earliest reports of this style of a cappella music involved African Americans. The earliest documented quartets all began in barber shops. In 1938, the first formal men's barbershop organization was formed, known as the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America (S.P.E.B.S.Q.S.A), and in 2004 rebranded itself and officially changed its public name to the Barbershop Harmony Society (BHS). Today the BHS has about 22,000 members in approximately 800 chapters across the United States and Canada, and the barbershop style has spread around the world with organizations in many other countries. The Barbershop Harmony Society provides a highly organized competition structure for a cappella quartets and choruses singing in the barbershop style. In 1945, the first formal women's barbershop organization, Sweet Adelines, was formed. In 1953, Sweet Adelines became an international organization, although it did not change its name to Sweet Adelines International until 1991. The membership of nearly 25,000 women, all singing in English, includes choruses in most of the fifty United States as well as in Australia, Canada, Finland, Germany, Ireland, Japan, New Zealand, Spain, Sweden, the United Kingdom, and the Netherlands. Headquartered in Tulsa, Oklahoma, the organization encompasses more than 1,200 registered quartets and 600 choruses. In 1959, a second women's barbershop organization started as a break off from Sweet Adelines due to ideological differences. Based on democratic principles which continue to this day, Harmony, Inc. is smaller than its counterpart, but has an atmosphere of friendship and competition. With about 2,500 members in the United States and Canada, Harmony, Inc. uses the same rules in contest that the Barbershop Harmony Society uses. Harmony, Inc. is registered in Providence, Rhode Island. Amateur and high school The popularity of a cappella among high schools and amateurs was revived by television shows and movies such as Glee and Pitch Perfect. High school groups may have conductors or student leaders who keep the tempo for the group, or beatboxers/vocal percussionists. Since 2013, summer training programs have appeared, such as A Cappella Academy in Los Angeles, California (founded by Ben Bram, Rob Dietz, and Avi Kaplan) and Camp A Cappella in Dayton, Ohio (founded by Deke Sharon and Brody McDonald). These programs teach about different aspects of a cappella music, including vocal performance, arranging, and beatboxing/vocal percussion. In other countries Afghanistan The Islamic Emirate of Afghanistan has no official anthem because of views by the Taliban of music as un-Islamic. However, the de facto national anthem of Afghanistan is an a cappella nasheed, as musical instruments are virtually banned as corrupting and un-Islamic. Iran The first a cappella group in Iran is the Damour Vocal Band, which was able to perform on national television despite a ban on women singing. Pakistan The musical show Strepsils Stereo is credited for introducing the art of a cappella in Pakistan. Sri Lanka Composer Dinesh Subasinghe became the first Sri Lankan to write a cappella pieces for SATB choirs. He wrote "The Princes of the Lost Tribe" and "Ancient Queen of Somawathee" for Menaka De Sahabandu and Bridget Helpe's choirs, respectively, based on historical incidents in ancient Sri Lanka. Voice Print is also a professional a cappella music group in Sri Lanka. Sweden The European a cappella tradition is especially strong in the countries around the Baltic and perhaps most so in Sweden as described by Richard Sparks in his doctoral thesis The Swedish Choral Miracle in 2000. Swedish a cappella choirs have over the last 25 years won around 25% of the annual prestigious European Grand Prix for Choral Singing (EGP) that despite its name is open to choirs from all over the world (see list of laureates in the Wikipedia article on the EGP competition). The reasons for the strong Swedish dominance are as explained by Richard Sparks manifold; suffice to say here that there is a long-standing tradition, an unusually large proportion of the populations (5% is often cited) regularly sing in choirs, the Swedish choral director Eric Ericson had an enormous impact on a cappella choral development not only in Sweden but around the world, and finally there are a large number of very popular primary and secondary schools ('music schools') with high admission standards based on auditions that combine a rigid academic regimen with high level choral singing on every school day, a system that started with Adolf Fredrik's Music School in Stockholm in 1939 but has spread over the country. United Kingdom A cappella has gained attention in the UK in recent years, with many groups forming at British universities by students seeking an alternative singing pursuit to traditional choral and chapel singing. This movement has been bolstered by organisations such as The Voice Festival UK. Western collegiate It is not clear exactly where collegiate a cappella began. The Rensselyrics of Rensselaer Polytechnic Institute (formerly known as the RPI Glee Club), established in 1873 is perhaps the oldest known collegiate a cappella group. The longest continuously singing group is probably The Whiffenpoofs of Yale University, which was formed in 1909 and once included Cole Porter as a member. Collegiate a cappella groups grew throughout the 20th century. Some notable historical groups formed along the way include Colgate University's The Colgate 13 (1942), Dartmouth College's Aires (1946), Cornell University's Cayuga's Waiters (1949) and The Hangovers (1968), the University of Maine Maine Steiners (1958), the Columbia University Kingsmen (1949), the Jabberwocks of Brown University (1949), and the University of Rochester YellowJackets (1956). All-women a cappella groups followed shortly, frequently as a parody of the men's groups: the Smiffenpoofs of Smith College (1936), the Night Owls of Vassar College (1942), The Shwiffs of Connecticut College (The She-Whiffenpoofs, 1944), and The Chattertocks of Brown University (1951). A cappella groups exploded in popularity beginning in the 1990s, fueled in part by a change in style popularized by the Tufts University Beelzebubs and the Boston University Dear Abbeys. The new style used voices to emulate modern rock instruments, including vocal percussion/"beatboxing". Some larger universities now have multiple groups. Groups often join one another in on-campus concerts, such as the Georgetown Chimes' Cherry Tree Massacre, a 3-weekend a cappella festival held each February since 1975, where over a hundred collegiate groups have appeared, as well as International Quartet Champions The Boston Common and the contemporary commercial a cappella group Rockapella. Co-ed groups have produced many up-and-coming and major artists, including John Legend, an alumnus of the Counterparts at the University of Pennsylvania, Sara Bareilles, an alumna of Awaken A Cappella at University of California, Los Angeles, and Mindy Kaling, an alumna of the Rockapellas at Dartmouth College. Mira Sorvino is an alumna of the Harvard-Radcliffe Veritones of Harvard College, where she had the solo on Only You by Yaz. Jewish-interest groups such as Queens College's Tizmoret, Tufts University's Shir Appeal, University of Chicago's Rhythm and Jews, Binghamton University's Kaskeset, Ohio State University's Meshuganotes, Rutgers University's Kol Halayla, New York University's Ani V'Ata, University of California, Los Angeles's Jewkbox, and Yale University's Magevet are also gaining popularity across the U.S. Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second, third, fourth, and fifth season, won by Committed, Pentatonix, Home Free, and The Melodores from Vanderbilt University respectively. Each year, hundreds of Collegiate a cappella groups submit their strongest songs in a competition to be on The Best of College A Cappella (BOCA), an album compilation of tracks from the best college a cappella groups around the world. The album is produced by Varsity Vocals – which also produces the International Championship of Collegiate A Cappella – and Deke Sharon. ). According to ethnomusicologist Joshua S. Dunchan, "BOCA carries considerable cache and respect within the field despite the appearance of other compilations in part, perhaps, because of its longevity and the prestige of the individuals behind it." Collegiate a cappella groups may also submit their tracks to Voices Only, a two-disc series released at the beginning of each school year. A Voices Only album has been released every year since 2005. In addition, from 2014 to 2019, female-identifying a cappella groups had the opportunity to send their strongest song tracks to the Women's A Cappella Association (WACA) for its annual best of women's a cappella album. WACA offered another medium for women's voices to receive recognition and released an album every year from 2014 to 2019, featuring female-identifying groups from across the United States. The Women's A Cappella Association hosted seven annual festivals in California before ending operations in 2019. South Asian collegiate South Asian a cappella features a mash-up of western and Indian/middle-eastern songs, which places it in the category of South Asian fusion music. A cappella is gaining popularity among South Asians with the emergence of primarily Hindi-English college groups. The first South Asian a cappella group was Penn Masala, founded in 1996 at the University of Pennsylvania. Co-ed South Asian a cappella groups are also gaining in popularity. The first co-ed South Asian a cappella was Anokha, from the University of Maryland, formed in 2001. Also, Dil se, another co-ed a cappella from UC Berkeley, hosts the "Anahat" competition at the University of California, Berkeley annually. Maize Mirchi, the co-ed a cappella group from the University of Michigan hosts "Sa Re Ga Ma Pella", an annual South Asian a cappella invitational with various groups from the Midwest. More South Asian a cappella groups from the Midwest are Chai Town from the University of Illinois Urbana-Champaign and Dhamakapella from Case Western Reserve University. Much like the ICCA competitions, the South Asian A Cappella competitive circuit is governed by the Association of South-Asian A Cappella, a nonprofit formed in 2016. The competitive circuit consists of qualifier, or bid competitions, as well as the national championship, All-American Awaaz. Swaram A Cappella from Texas A&M and Dhamakapella from Case Western Reserve University jointly hold the record for most All-American Awaaz Championships, with two apiece. Emulating instruments In addition to singing words, some a cappella singers also emulate instrumentation by reproducing instrumental sounds with their vocal cords and mouth, often pitched using specialised pitch pipes. One of the earliest 20th century practitioners of this method were The Mills Brothers whose early recordings of the 1930s clearly stated on the label that all instrumentation was done vocally. More recently, "Twilight Zone" by 2 Unlimited was sung a cappella to the instrumentation on the comedy television series Tompkins Square. Another famous example of emulating instrumentation instead of singing the words is the theme song for The New Addams Family series on Fox Family Channel (now Freeform). Groups such as Vocal Sampling and Undivided emulate Latin rhythms a cappella. In the 1960s, the Swingle Singers used their voices to emulate musical instruments to Baroque and Classical music. Vocal artist Bobby McFerrin is famous for his instrumental emulation. A cappella group Naturally Seven recreates entire songs using vocal tones for every instrument. The Swingle Singers used ad libs to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements. Beatboxing is performed often by shaping the mouth, making pops and clicks as pseudo-drum sounds. A popular phrase that beat boxers use to begin their training is the phrase "boots and cats". As the beat boxer progresses in their training, they remove the vowels and continue on from there, emulating a "bts n cts n" sound, a solid base for beginner beat boxers. The phrase has become popular enough to where Siri recites "Boots and Cats" when you ask it to beatbox. Jazz vocalist Petra Haden used a four-track recorder to produce an a cappella version of The Who Sell Out including the instruments and fake advertisements on her album Petra Haden Sings: The Who Sell Out in 2005. Haden has also released a cappella versions of Journey's "Don't Stop Believin'", The Beach Boys' "God Only Knows" and Michael Jackson's "Thriller".

Alicante () is a city and municipality in the Valencian Community, Spain. It is the capital of the province of Alicante and a historic Mediterranean port. The population of the city was 337,482 , the second-largest in the Valencian Community. Toponymy The name of the city echoes the Arabic name Laqant () or al-Laqant (), which in turn reflects the Latin Lucentum and Greek root Leuké (or Leuka), meaning "white". History The area around Alicante has been inhabited for over 7000 years. The first tribes of hunter-gatherers moved down gradually from Central Europe between 5000 and 3000 BC. Some of the earliest settlements were made on the slopes of Mount Benacantil. By 1000 BC Greek and Phoenician traders had begun to visit the eastern coast of Spain, establishing small trading ports and introducing the native Iberian tribes to the alphabet, iron, and the pottery wheel. The Carthaginian general Hamilcar Barca established the fortified settlement of Akra Leuké (Greek: , meaning "White Mountain" or "White Point"), in the mid-230s BC, which is generally presumed to have been on the site of modern Alicante. Although the Carthaginians conquered much of the land around Alicante, the Romans would eventually rule Hispania Tarraconensis for over 700 years. By the 5th century AD, Rome was in decline and the Roman predecessor town of Alicante, known as Lucentum (Latin), was more or less under the control of the Visigothic warlord Theudimer and thereafter under Visigothic rule from 400 to 700 A.D. The Goths did not put up much resistance to the Arab conquest of Medina Laqant at the beginning of the 8th century. The Moors ruled southern and eastern Spain until the 13th century Reconquista (Reconquest). Alicante was conquered again in 1247 by the Castilian king Alfonso X, but later passed to the Kingdom of Valencia in 1296 with King James II of Aragon. It gained the status of Royal Village (Vila Reial) with representation in the medieval Valencian Parliament (Corts Valencianes). After several decades of being the battlefield where the Crown of Castile and the Crown of Aragon clashed, Alicante became a major Mediterranean trading station exporting rice, wine, olive oil, oranges, and wool. But between 1609 and 1614 King Felipe III expelled thousands of Moriscos who had remained in Valencia after the Reconquista, due to their cooperation with Barbary pirates who continually attacked coastal cities and caused much harm to trade. This act cost the region dearly; with so many skilled artisans and agricultural labourers gone, the feudal nobility found itself sliding into bankruptcy. Conditions worsened in the early 18th century; after the War of Spanish Succession, Alicante went into a long, slow decline, surviving through the 18th and 19th centuries by making shoes and growing agricultural produce such as oranges and almonds, and thanks to its fisheries. The end of the 19th century witnessed a sharp recovery of the local economy with increasing international trade and the growth of the city harbour leading to increased exports of several products (particularly during World War I when Spain was a neutral country). During the early 20th century, Alicante was a minor capital that took profit from the benefit of Spain's neutrality during World War I, and that provided new opportunities for local industry and agriculture. The Rif War in the 1920s saw numerous alicantinos drafted to fight in the long and bloody campaigns in the former Spanish protectorate (northern Morocco) against the Rif rebels. The political unrest of the late 1920s led to the victory of Republican candidates in local council elections throughout the country, and the abdication of King Alfonso XIII. The proclamation of the Second Spanish Republic was much celebrated in the city on 14 April 1931. The Spanish Civil War broke out on 17 July 1936. Alicante was the last city loyal to the Republican government to be occupied by General Franco's troops on 1 April 1939, and its harbour saw the last Republican government officials fleeing the country. Vicious air bombings were targeted on Alicante during the three years of civil conflict, most notably the bombing by the Italian Aviazione Legionaria of the Mercado on 25 May 1938 in which more than 300 civilians perished. The port of Alicante was the site of the heroic episode of the British ship SS Stanbrook in 1939 at the end of the Spanish Civil War. His captain Archibald Dickson decided to rescue thousands of Spanish Republicans families during the night of 28th March 1939 under the bombing of the Nazis. From 1954 onwards many pied-noirs settled in the city (as many as 30,000, although other sources decrease the amount tenfold). Alicante had fostered strong links with Oran in the past, and a notable share of the population of the latter city during the French colonial period had ancestry in the province of Alicante. The immigration process accelerated after the independence of Algeria in 1962. The late 1950s and early 1960s saw the onset of a lasting transformation of the city by the tourist industry. Large buildings and complexes rose in nearby Albufereta, e.g. El Barco, and Playa de San Juan de Alicante, with the benign climate being the biggest draw to attract prospective buyers and tourists who kept the hotels reasonably busy. New construction benefited the whole economy, as the development of the tourism sector also spawned new businesses such as restaurants, bars, and other tourist-oriented enterprises. Also, the old airfield at Rabasa was closed and air traffic moved to the new El Altet Airport, which made a more convenient and modern facility for charter flights bringing tourists from northern European countries. When Franco died in 1975, his successor Juan Carlos I played his part as the living symbol of the transition of Spain to a democratic constitutional monarchy. The governments of regional communities were given constitutional status as nationalities, and their governments were given more autonomy, including that of the Valencian region, the Generalitat Valenciana. The Port of Alicante has been reinventing itself since the industrial decline the city suffered in the 1980s (with most mercantile traffic lost to Valencia's harbour). In recent years, the Port Authority has established it as one of the most important ports in Spain for cruises, with 72 calls to port made by cruise ships in 2007 bringing some 80,000 passengers and 30,000 crew to the city each year. The moves to develop the port for more tourism have been welcomed by the city and its residents, but the latest plans to develop an industrial estate in the port have caused great controversy. Geography Alicante is located in the southeast of the Iberian Peninsula, on the shores of the Mediterranean Sea. Some orographic features rise over the largely flat terrain where the city is built on including the Cabo de la Huerta, the Serra Grossa, the Tosal and the Benacantil hills. Located in an arid territory, Alicante lacks any meaningful permanent water stream. There are however several stream beds correspondent to intermittent ramblas. There was a swamp area in the northeast of the municipality, l'Albufereta, yet it was dried up in 1928. The municipality has two exclaves in the mainland: Monnegre (between the municipalities of San Vicente del Raspeig, Mutxamel, Busot and Jijona), and Cabeçó d'Or; the latter comprises part of the namesake Cabeçó d'Or mountain (including the summit, 1209 metres above sea level). The small island of Tabarca, 8 nautical miles to the south of the city, also belongs to the municipality. The foot of the main staircase of the City Hall Building (Ayuntamiento) is the zero point (cota cero), used as the point of reference for measuring the height above or below sea level of any point in Spain, due to the marginal tidal variations of the Mediterranean sea at Alicante. Economy Until the global recession which started in 2008, Alicante was one of the fastest-growing cities in Spain. The boom depended partly on tourism directed to the beaches of the Costa Blanca and particularly on the second residence-construction boom which started in the 1960s and revived again by the late 1990s. Services and public administration also play a major role in the city's economy. The construction boom has raised many environmental concerns and both the local autonomous government and city council are under scrutiny by the European Union. The construction surge was the subject of hot debates among politicians and citizens alike. The latest of many public battles concerns the plans of the Port Authority of Alicante to construct an industrial estate on reclaimed land in front of the city's coastal strip, in breach of local, national, and European regulations. (See Port of Alicante for details). The city serves as the headquarters of the European Union Intellectual Property Office and a sizeable population of European public workers live there. The campus of the University of Alicante lies in San Vicente del Raspeig, bordering the city of Alicante to the north. More than 25,000 students attend the university. Between 2005 and 2012 Ciudad de la Luz (Ciutat de la Llum), one of the largest film studios in Europe, had its base in Alicante. The studio shot Spanish and international movies such as Asterix at the Olympic Games by Frédéric Forestier and Thomas Langmann, and Manolete by Menno Meyjes. It was shut down in 2012 for violating European competition law. Government and administration Luis Barcala of the People's Party has been the mayor of Alicante since 19 April 2018. He became mayor after the resignation of Gabriel Echávarri, when the councillor Nerea Belmonte defected from Guanyar Alacant and refused to support the Socialist Party replacement candidate Eva Montesinos. Gabriel Echávarri of the Socialist Party (PSOE) was the mayor of the city from 13 June 2015 until April 2018, following the municipal elections on 24 May 2015. He was supported by the votes from his group (6), plus those from leftist parties Guanyar Alacant (6) and Compromís (3), as well as from the centre-right party Ciudadanos (6). The People's Party (Partido Popular, PP), with only 8 elected seats, lost the majority. On April he resigned due to various judicial issues and was temporarily substituted by the councillor Eva Montesinos. In the previous municipal elections of May 2011, Sonia Castedo of People's Party won the elections with an absolute majority, but resigned in December 2014 due to her involvement in several corruption scandals, at present being under investigation. Her fellow party member Miguel Valor went on to become mayor up until Echávarri's election. Climate Alicante has mild winter temperatures, hot summers, and little rain, concentrated in equinoctial periods. Like the rest of the Province of Alicante itself, which has a range of dry climate types, the city has a hot semi-arid climate (BSh) according to the Köppen climate classification. Daily variations in temperature are generally small because of the stabilising influence of the sea, although occasional periods of westerly wind can produce temperature changes of or more. Seasonal temperature variations are also relatively small, meaning that winters are mild and summers are hot. The average rainfall is per year. The cold drop means that September and October are the wettest months. Rarely, the rainfall can be torrential, reaching over in a 24-hour period, leading to severe flooding. Because of this irregularity, only 35 rainy days are observed on average per year, and the annual number of sunshine hours is 2,851. The record maximum temperature of was observed on 13 August 2022. The record minimum temperature of was recorded on 12 February 1956. The worst flooding in the city's modern history occurred on 30 September 1997 when of rain fell within six hours. Temperatures below are very rare; the last recorded snowfall occurred in 1926. Alicante enjoys one of the sunniest and warmest winter daytime temperatures in mainland Europe. Demographics The official population of Alicante in 2022 was 338,577 inhabitants and 768,194 in the metropolitan area "Alicante-Elche". As of 2022, about 17.7% of the population is foreign, 62195 people, most of them immigrants who have arrived in the previous 20 years. Besides which, there is an estimation of additional thousands coming from countries outside the EU (mostly from the African continent) that are under illegal alien status and therefore are not accounted for in official population figures. The real percentage of foreign residents is higher, since the Alicante metropolitan area is home to many Northern European retirees who are officially still residents of their own countries. A sizable number of semi-permanent residents are Spanish nationals who officially still live in other areas of Spain. Transportation Alicante Airport outranks the Valencia Airport, being the busiest airport in the Valencian Community, and among the busiest airports in Spain after Madrid, Barcelona, Palma de Mallorca and Málaga. It is connected with Madrid and Barcelona by frequent Iberia and Vueling flights, and with many Western European cities through carriers such as Ryanair, Easyjet and Jet2.com. There are also regular flights to Algeria. Alicante railway station is used by Cercanías Murcia/Alicante commuter rail services linking Alicante with suburbs and Murcia. Long-range Renfe trains run frequently to Madrid, Barcelona, and Valencia. In 2013, the Madrid–Levante high-speed rail network was extended to Alicante station, allowing AVE high-speed rail services to link to Madrid via Villena AV, Albacete-Los Llanos and Cuenca-Fernando Zóbel. Alicante Tram connects the city with outlying settlements along Costa Blanca. , electric tram-trains run up to Benidorm, and diesel trains go further to Dénia. The city has regular ferry services to the Balearic Islands and Algeria. The city is strongly fortified, with a spacious harbour. Main sights Amongst the most notable features of the city are the Castle of Santa Bárbara and the port of Alicante. The latter was the subject of bitter controversy in 2006–2007 as residents battled, successfully, to keep it from being changed into an industrial estate. The Santa Bárbara castle is situated on Mount Benacantil, overlooking the city. The tower (La Torreta) at the top, is the oldest part of the castle, while part of the lowest zone and the walls were constructed later in the 18th century. The promenade Explanada de España, lined by palm trees, is paved with 6.5 million marble floor tiles creating a wavy form. The Promenade extends from the Port of Alicante to the Gran Vía and ends at the famous statue of Mark Hersch. For the people of Alicante, the promenade is the meeting place for the traditional Spanish paseo, or stroll along the waterfront in the evenings, and a venue for outdoor musical concerts. At the end of the promenade is a monument by the artist Bañuls of the 19th century. Barrio de la Santa Cruz is a colourful quarter of the old city, situated southwest of Santa Bárbara castle. Its small houses climb up the hill leading to the walls and the castle, through narrow streets decorated with flags and tubs of flowers. L'Ereta Park is situated on the foothills of Mount Benacantil. It runs from the Santa Bárbara castle down to the old part of Alicante and consists of several levels, routes, decks, and rest stops which offer a panoramic view overlooking the city. El Palmeral Park is one of the favourite parks of Alicante's citizens. It includes walking trails, children's playgrounds, ponds and brooks, picnic tables, and an auditorium for concerts. Just a few kilometers from Alicante on the Mediterranean Sea lies Tabarca island. What was once a haven for Barbary pirates is now a tourist attraction. Other sights include: Basilica of Santa María (14th–16th centuries), built-in Gothic style over the former main mosque. Other features include the high altar, in Rococo style, and the portal, in Baroque style, both from the 18th century. Co-cathedral of St. Nicholas of Bari (15th–18th centuries), also built over a mosque. It is the main church of Alicante and the bishop's seat. Monastery of Santa Faz (15th century), located outside the city, in Baroque style. Defence towers of the Huerta de Alicante (15th–18th centuries), built to defend against the Barbary pirates. Today some 20 towers are still extant. Baroque Casa de La Asegurada (1685), the most ancient civil building in the city. (c. XVII). Today it is home to the Museum of Contemporary Art of Alicante. Casa consistorial de Alicante (18th century), also in Baroque style. Convent of the Canónigas de San Agustín (18th century). Gravina Palace (1748–1808), nowadays hosting Gravina Museum of Fine Arts. Castle of San Fernando. There are a dozen museums in Alicante. On exhibition at the Archaeological Museum of Alicante (MARQ) are local artifacts dating from 100,000 years ago until the early 20th century. The collection is divided into different rooms representing three divisions of archaeological methodology: ground, urban and underwater archaeology, with dioramas, audiovisual and interactive zones. The archaeological museum won the European Museum of the Year Award in 2004. Gravina Museum of Fine Arts presents several paintings and sculptures from the 16th century to the 19th century. Asegurada Museum of Contemporary Art houses a major collection of twentieth-century art, composed mainly of works donated by Eusebio Sempere. Festivals The most important festival, the Bonfires of Saint John (Hogueras de San Juan / Fogueres de Sant Joan), takes place during the summer solstice. This is followed a week later by five nights of firework and pyrotechnic contests between companies on the urban beach Playa del Postiguet. Another well-known festival is Moors and Christians (Moros y Cristianos) in Altozano or San Blas district. Overall, the city boasts a year-round nightlife for the enjoyment of tourists, residents, and a large student population of the University of Alicante. The nightlife social scene tends to shift to nearby Playa de San Juan during the summer months. Every summer in Alicante, a two-month-long programme of music, theatre and dance is staged in the Paseo del Puerto. Sport For the 2023/24 season Alicante has two football clubs in the top 4 levels of Spanish football; Hércules CF and CF Intercity. For the 2023/24 season Hércules compete in Segunda Federación, the 4th level and are well known as they played in La Liga (the Spanish Premier Division) during the 1996/1997 season and again in 2010/2011. They have had many famous players such as David Trezeguet, Royston Drenthe and Nelson Valdez. Hércules are also known for their victory over Barcelona in 1997 which led to Real Madrid winning the league. Home games are played at the 30,000-capacity José Rico Pérez Stadium. The city's other club, Alicante CF, who played in the Third Division, was dissolved in 2014 due to economic problems. They were replaced in 2017 by newly formed club CF Intercity, who compete in Primera Federación, the 3rd level of Spanish football, in the 23/24 season and play at Estadio Antonio Solana. Basketball club (HLA Alicante) Lucentum Alicante participates in the Spanish basketball league. It plays in the Centro de Tecnificación de Alicante. Alicante serves as headquarters and the starting point of the Volvo Ocean Race, a yacht race around the world. The latest race sailed in January 2023.

Muhi al-Din Muhammad ( – 3 March 1707), commonly known as ( ) and by his regnal name Alamgir I ( ), was the sixth Mughal emperor, reigning from 1658 until his death in 1707. Under his emperorship, the Mughal Empire reached its greatest extent with territory spanning nearly the entirety of the Indian subcontinent. Aurangzeb belonged to the aristocratic Timurid dynasty, held administrative and military posts under his father Shah Jahan () and gained recognition as an accomplished military commander. Aurangzeb served as the viceroy of the Deccan in 1636–1637 and the governor of Gujarat in 1645–1647. He jointly administered the provinces of Multan and Sindh in 1648–1652 and continued expeditions into the neighboring Safavid territories. In September 1657, Shah Jahan nominated his eldest and liberalist son Dara Shikoh as his successor, a move repudiated by Aurangzeb, who proclaimed himself emperor in February 1658. In April 1658, Aurangzeb defeated the allied army of Shikoh and the Kingdom of Marwar at the battle of Dharmat. Aurangzeb's decisive victory at the battle of Samugarh in May 1658 cemented his sovereignty and his suzerainty was acknowledged throughout the Empire. After Shah Jahan recovered from illness in July 1658, Aurangzeb declared him incompetent to rule and imprisoned his father in the Agra Fort. Under Aurangzeb's emperorship, the Mughals reached its greatest extent with their territory spanning nearly the entire Indian subcontinent. His reign is characterized by a period of rapid military expansion, with several dynasties and states being overthrown by the Mughals. His conquests acquired him the regnal title Alamgir ('Conqueror'). The Mughals also surpassed Qing China as the world's largest economy and biggest manufacturing power. The Mughal military gradually improved and became one of the strongest armies in the world. A staunch Muslim, Aurangzeb is credited with the construction of numerous mosques and patronizing works of Arabic calligraphy. He successfully imposed the Fatawa 'Alamgiri as the principal regulating body of the empire and prohibited religiously forbidden activities in Islam. Although Aurangzeb suppressed several local revolts, he maintained cordial relations with foreign governments. Aurangzeb has been described as one of the most controversial rulers in Indian history, though his rule has also been the subject of praise. Multiple interpretations of Aurangzeb's life and reign over the years by critics have led to a very complicated legacy. Some argue that his policies abandoned his predecessors' legacy of pluralism and religious tolerance, citing his introduction of the jizya tax and other policies based on Islamic ethics; his demolition of Hindu temples; the executions of his elder brother Dara Shikoh, King Sambhaji of Maratha and Sikh Guru Tegh Bahadur; and the prohibition and supervision of behaviour and activities that are forbidden in Islam such as gambling, fornication, and consumption of alcohol and narcotics. At the same time, some historians question the historical authenticity of the claims of his critics, arguing that his destruction of temples has been exaggerated, and noting that he built more temples than he destroyed, paid for their maintenance, employed significantly more Hindus in his imperial bureaucracy than his predecessors, and opposed bigotry against Hindus and Shia Muslims. Early life Aurangzeb was born in Dahod in . His father was Emperor Shah Jahan (), who hailed from the Mughal house of the Timurid dynasty. The latter was descended from Emir Timur (), the founder of the Timurid Empire. Aurangzeb's mother Mumtaz Mahal was the daughter of the Persian nobleman Asaf Khan, who was the youngest son of vizier Mirza Ghiyas. Aurangzeb was born during the reign of his patrilineal grandfather Jahangir (), the fourth emperor of the Mughal Empire. In June 1626, after an unsuccessful rebellion by his father, eight-year-old Aurangzeb and his brother Dara Shikoh were sent to the Mughal court in Lahore as hostages of their grandfather Jahangir and his wife, Nur Jahan, as part of their father's pardon deal. After Jahangir died in 1627, Shah Jahan emerged victorious in the ensuing war of succession to the Mughal throne. Aurangzeb and his brother were consequently reunited with Shah Jahan in Agra. Aurangzeb received a Mughal princely education covering subjects like combat, military strategy, and administration. His curriculum also included scholarly areas like Islamic studies and Turkic and Persian literature. Aurangzeb grew up fluent in the Hindi of his time. On 28 May 1633, Aurangzeb escaped death when a powerful war elephant stampeded through the Mughal imperial encampment. He rode against the elephant and struck its trunk with a lance, and successfully defended himself from being crushed. Aurangzeb's valour was appreciated by his father who conferred him the title of Bahadur (Brave) and had him weighed in gold and presented gifts worth Rs. 200,000. This event was celebrated in Persian and Urdu verses, and Aurangzeb said: Ancestry Early military campaigns and administration Bundela War Aurangzeb was nominally in charge of the force sent to Bundelkhand with the intent of subduing the rebellious ruler of Orchha, Jhujhar Singh, who had attacked another territory in defiance of Shah Jahan's policy and was refusing to atone for his actions. By arrangement, Aurangzeb stayed in the rear, away from the fighting, and took the advice of his generals as the Mughal Army gathered and commenced the siege of Orchha in 1635. The campaign was successful and Singh was removed from power. Viceroy of the Deccan Aurangzeb was appointed viceroy of the Deccan in 1636. After Shah Jahan's vassals had been devastated by the alarming expansion of Ahmednagar during the reign of the Nizam Shahi boy-prince Murtaza Shah III, the emperor dispatched Aurangzeb, who in 1636 brought the Nizam Shahi dynasty to an end. In 1637, Aurangzeb married the Safavid princess Dilras Banu, posthumously known as Rabia-ud-Daurani. She was his first wife and chief consort as well as his favourite. He also had an infatuation with a slave girl, Hira Bai, whose death at a young age greatly affected him. In his old age, he was under the charms of his concubine, Udaipuri Mahal. The latter had formerly been a companion to Dara Shukoh. In the same year, 1637, Aurangzeb was placed in charge of annexing the small Rajput kingdom of Baglana, which he did with ease. In 1638, Aurangzeb married Nawab Bai, later known as Rahmat al-Nisa. That same year, Aurangzeb dispatched an army to subdue the Portuguese coastal fortress of Daman, however his forces met stubborn resistance and were eventually repulsed at the end of a long siege. At some point, Aurangzeb married Aurangabadi Mahal, who was a Circassian or Georgian. In 1644, Aurangzeb's sister, Jahanara, was burned when the chemicals in her perfume were ignited by a nearby lamp while in Agra. This event precipitated a family crisis with political consequences. Aurangzeb suffered his father's displeasure by not returning to Agra immediately but rather three weeks later. Shah Jahan had been nursing Jahanara back to health in that time and thousands of vassals had arrived in Agra to pay their respects. Shah Jahan was outraged to see Aurangzeb enter the interior palace compound in military attire and immediately dismissed him from his position of viceroy of the Deccan; Aurangzeb was also no longer allowed to use red tents or to associate himself with the official military standard of the Mughal emperor. Other sources tell us that Aurangzeb was dismissed from his position because Aurangzeb left the life of luxury and became a faqir. Governor of Gujarat In 1645, he was barred from the court for seven months and mentioned his grief to fellow Mughal commanders. Thereafter, Shah Jahan appointed him governor of Gujarat. His rule in Gujarat was marked with religious disputes but he was rewarded for bringing stability. Governor of Balkh In 1647, Shah Jahan moved Aurangzeb from Gujarat to be governor of Balkh, replacing a younger son, Murad Baksh, who had proved ineffective there. The area was under attack from Uzbek and Turkmen tribes. While the Mughal artillery and muskets were a formidable force, so too were the skirmishing skills of their opponents. The two sides were in stalemate and Aurangzeb discovered that his army could not live off the land, which was devastated by war. With the onset of winter, he and his father had to make a largely unsatisfactory deal with the Uzbeks, giving away territory in exchange for nominal recognition of Mughal sovereignty. The Mughal force suffered still further with attacks by Uzbeks and other tribesmen as it retreated through the snow to Kabul. By the end of this two-year campaign, into which Aurangzeb had been plunged at a late stage, a vast sum of money had been expended for little gain. Further inauspicious military involvements followed, as Aurangzeb was appointed governor of Multan and Sindh. His efforts in 1649 and 1652 to dislodge the Safavids at Kandahar, which they had recently retaken after a decade of Mughal control, both ended in failure as winter approached. The logistical problems of supplying an army at the extremity of the empire, combined with the poor quality of armaments and the intransigence of the opposition have been cited by John Richards as the reasons for failure, and a third attempt in 1653, led by Dara Shikoh, met with the same outcome. 2nd term as Viceroy of the Deccan Aurangzeb became viceroy of the Deccan again after he was replaced by Dara Shukoh in the attempt to recapture Kandahar. Aurangzeb regretted this and harboured feelings that Shikoh had manipulated the situation to serve his own ends. Aurangbad's two jagirs (land grants) were moved there as a consequence of his return and, because the Deccan was a relatively impoverished area, this caused him to lose out financially. So poor was the area that grants were required from Malwa and Gujarat in order to maintain the administration and the situation caused ill-feeling between father and son. Shah Jahan insisted that things could be improved if Aurangzeb made efforts to develop cultivation. Aurangzeb appointed Murshid Quli Khan to extend to the Deccan the zabt revenue system used in northern India. Murshid Quli Khan organised a survey of agricultural land and a tax assessment on what it produced. To increase revenue, Murshid Quli Khan granted loans for seed, livestock, and irrigation infrastructure. The Deccan returned to prosperity, Aurangzeb proposed to resolve the situation by attacking the dynastic occupants of Golconda (the Qutb Shahis) and Bijapur (the Adil Shahis). As an adjunct to resolving the financial difficulties, the proposal would also extend Mughal influence by accruing more lands. Aurangzeb advanced against the Sultan of Bijapur and besieged Bidar. The Kiladar (governor or captain) of the fortified city, Sidi Marjan, was mortally wounded when a gunpowder magazine exploded. After twenty-seven days of hard fighting, Bidar was captured by the Mughals and Aurangzeb continued his advance. Again, he was to feel that Dara had exerted influence on his father: believing that he was on the verge of victory in both instances, Aurangzeb was frustrated that Shah Jahan chose then to settle for negotiations with the opposing forces rather than pushing for complete victory. War of succession The four sons of Shah Jahan all held governorships during their father's reign. The emperor favoured the eldest, Dara Shikoh. This had caused resentment among the younger three, who sought at various times to strengthen alliances between themselves and against Dara. There was no Mughal tradition of primogeniture, the systematic passing of rule, upon an emperor's death, to his eldest son. Instead it was customary for sons to overthrow their father and for brothers to war to the death among themselves. Historian Satish Chandra says that "In the ultimate resort, connections among the powerful military leaders, and military strength and capacity [were] the real arbiters". The contest for power was primarily between Dara Shikoh and Aurangzeb because, although all four sons had demonstrated competence in their official roles, it was around these two that the supporting cast of officials and other influential people mostly circulated. There were ideological differences – Dara was an intellectual and a religious liberal in the mould of Akbar, while Aurangzeb was much more conservative – but, as historians Barbara D. Metcalf and Thomas R. Metcalf say, "To focus on divergent philosophies neglects the fact that Dara was a poor general and leader. It also ignores the fact that factional lines in the succession dispute were not, by and large, shaped by ideology." Marc Gaborieau, professor of Indian studies at l'École des Hautes Études en Sciences Sociales, explains that "The loyalties of [officials and their armed contingents] seem to have been motivated more by their own interests, the closeness of the family relation and above all the charisma of the pretenders than by ideological divides." Muslims and Hindus did not divide along religious lines in their support for one pretender or the other nor, according to Chandra, is there much evidence to support the belief that Jahanara and other members of the royal family were split in their support. Jahanara, certainly, interceded at various times on behalf of all of the princes and was well-regarded by Aurangzeb even though she shared the religious outlook of Dara. In 1656, a general under Qutb Shahi dynasty named Musa Khan led an army of 12,000 musketeers to attack Aurangzeb, who was besieging Golconda Fort. Later in the same campaign, Aurangzeb, in turn, rode against an army consisting of 8,000 horsemen and 20,000 Karnataki musketeers. Having made clear that he wanted Dara to succeed him, Shah Jahan became ill with stranguary in 1657 and was closeted under the care of his favourite son in the newly built city of Shahjahanabad (Old Delhi). Rumours of the death of Shah Jahan abounded and the younger sons were concerned that Dara might be hiding it for Machiavellian reasons. Thus, they took action: Shah Shuja In Bengal, where he had been governor since 1637, Prince Muhammad Shuja crowned himself King at RajMahal, and brought his cavalry, artillery and river flotilla upriver towards Agra. Near Varanasi his forces confronted a defending army sent from Delhi under the command of Prince Sulaiman Shukoh, son of Dara Shukoh, and Raja Jai Singh while Murad did the same in his governorship of Gujarat and Aurangzeb did so in the Deccan. It is not known whether these preparations were made in the mistaken belief that the rumours of death were true or whether the challengers were just taking advantage of the situation. After regaining some of his health, Shah Jahan moved to Agra and Dara urged him to send forces to challenge Shah Shuja and Murad, who had declared themselves rulers in their respective territories. While Shah Shuja was defeated at Banares in February 1658, the army sent to deal with Murad discovered to their surprise that he and Aurangzeb had combined their forces, the two brothers having agreed to partition the empire once they had gained control of it. The two armies clashed at Dharmat in April 1658, with Aurangzeb being the victor. Shuja was being chased through Bihar and the victory of Aurangzeb proved this to be a poor decision by Dara Shikoh, who now had a defeated force on one front and a successful force unnecessarily pre-occupied on another. Realising that his recalled Bihar forces would not arrive at Agra in time to resist the emboldened Aurangzeb's advance, Dara scrambled to form alliances in order but found that Aurangzeb had already courted key potential candidates. When Dara's disparate, hastily concocted army clashed with Aurangzeb's well-disciplined, battle-hardened force at the battle of Samugarh in late May, neither Dara's men nor his generalship were any match for Aurangzeb. Dara had also become over-confident in his own abilities and, by ignoring advice not to lead in battle while his father was alive, he cemented the idea that he had usurped the throne. "After the defeat of Dara, Shah Jahan was imprisoned in the fort of Agra where he spent eight long years under the care of his favourite daughter Jahanara." Aurangzeb then broke his arrangement with Murad Baksh, which probably had been his intention all along. Instead of looking to partition the empire between himself and Murad, he had his brother arrested and imprisoned at Gwalior Fort. Murad was executed on 4 December 1661, ostensibly for the murder of the diwan of Gujarat sometime earlier. The allegation was encouraged by Aurangzeb, who caused the diwan's son to seek retribution for the death under the principles of Sharia law. Meanwhile, Dara gathered his forces, and moved to the Punjab. The army sent against Shuja was trapped in the east, its generals Jai Singh and Dilir Khan submitted to Aurangzeb, but Dara's son, Suleiman Shikoh, escaped. Aurangzeb offered Shah Shuja the governorship of Bengal. This move had the effect of isolating Dara Shikoh and causing more troops to defect to Aurangzeb. Shah Shuja, who had declared himself emperor in Bengal began to annex more territory and this prompted Aurangzeb to march from Punjab with a new and large army that fought during the battle of Khajwa, where Shah Shuja and his chain-mail armoured war elephants were routed by the forces loyal to Aurangzeb. Shah Shuja then fled to Arakan (in present-day Burma), where he was executed by the local rulers. With Shuja and Murad disposed of, and with his father immured in Agra, Aurangzeb pursued Dara Shikoh, chasing him across the north-western bounds of the empire. Aurangzeb claimed that Dara was no longer a Muslim and accused him of poisoning the Mughal Grand Vizier Saadullah Khan. After a series of battles, defeats and retreats, Dara was betrayed by one of his generals, who arrested and bound him. In 1658, Aurangzeb arranged his formal coronation in Delhi. On 10 August 1659, Dara was executed on grounds of apostasy and his head was sent to Shahjahan. The first prominent execution of Aurangzeb was that of his brother Prince Dara Shikoh, who was accused of being influenced by Hinduism although some sources argue it was done for political reasons. Aurangzeb had his allied brother Prince Murad Baksh held for murder, judged and then executed. Aurangzeb is accused of poisoning his imprisoned nephew Sulaiman Shikoh. Having secured his position, Aurangzeb confined his frail father at the Agra Fort but did not mistreat him. Shah Jahan was cared for by Jahanara and died in 1666. Reign Bureaucracy Aurangzeb's imperial bureaucracy employed significantly more Hindus than that of his predecessors. Between 1679 and 1707, the number of Hindu officials in the Mughal administration rose by half, to represent 31.6% of Mughal nobility, the highest in the Mughal era. Many of them were Marathas and Rajputs, who were his political allies. However, Aurangzeb encouraged high ranking Hindu officials to convert to Islam. Economy Under his reign, the Mughal Empire contributed to the world's GDP by nearly 25%, surpassing Qing China, making it the world's largest economy and biggest manufacturing power, more than the entirety of Western Europe, and its largest and wealthiest subdivision, the Bengal Subah, signaled proto-industrialization. Establishment of Islamic law Aurangzeb was an orthodox Muslim ruler. Subsequent to the policies of his three predecessors, he endeavored to make Islam a dominant force in his reign. However these efforts brought him into conflict with the forces that were opposed to this revival. Aurangzeb was a follower of the Mujaddidi Order and a disciple of the son of the Punjabi saint, Ahmad Sirhindi. He sought to establish Islamic rule as instructed and inspired by him. Historian Katherine Brown has noted that "The very name of Aurangzeb seems to act in the popular imagination as a signifier of politico-religious bigotry and repression, regardless of historical accuracy." The subject has also resonated in modern times with popularly accepted claims that he intended to destroy the Bamiyan Buddhas. As a political and religious conservative, Aurangzeb chose not to follow the secular-religious viewpoints of his predecessors after his ascension. He made no mention of the Persian concept of kinship, the Farr-i-Aizadi, and based his rule on the Quranic concept of kingship. Shah Jahan had already moved away from the liberalism of Akbar, although in a token manner rather than with the intent of suppressing Hinduism, and Aurangzeb took the change still further. Though the approach to faith of Akbar, Jahangir and Shah Jahan was more syncretic than Babur, the founder of the empire, Aurangzeb's position is not so obvious. His emphasis on sharia competed, or was directly in conflict, with his insistence that zawabit or secular decrees could supersede sharia. The chief qazi refusing to crown him in 1659, Aurangzeb had a political need to present himself as a "defender of the sharia" due to popular opposition to his actions against his father and brothers. Despite claims of sweeping edicts and policies, contradictory accounts exist. Historian Katherine Brown has argued that Aurangzeb never imposed a complete ban on music. He sought to codify Hanafi law by the work of several hundred jurists, called Fatawa 'Alamgiri. It is possible the War of Succession and continued incursions combined with Shah Jahan's spending made cultural expenditure impossible. He learnt that at Multan, Thatta, and particularly at Varanasi, the teachings of Hindu Brahmins attracted numerous Muslims. He ordered the subahdars of these provinces to demolish the schools and the temples of non-Muslims. Aurangzeb also ordered subahdars to punish Muslims who dressed like non-Muslims. The executions of the antinomian Sufi mystic Sarmad Kashani and the ninth Sikh Guru Tegh Bahadur bear testimony to Aurangzeb's religious policy; the former was beheaded on multiple accounts of heresy, the latter, according to Sikhs, because he objected to Aurangzeb's forced conversions. Aurangzeb had also banned the celebration of the Zoroastrian festival of Nauroz along with other un-Islamic ceremonies, and encouraged conversions to Islam; instances of persecution against particular Muslim factions were also reported. Taxation policy Shortly after coming to power, Aurangzeb remitted more than 80 long-standing taxes affecting all of his subjects. In 1679, Aurangzeb chose to re-impose jizya, a military tax on non-Muslim subjects in lieu of military service, after an abatement for a span of hundred years, in what was critiqued by many Hindu rulers, family-members of Aurangzeb, and Mughal court-officials. The specific amount varied with the socioeconomic status of a subject and tax-collection were often waived for regions hit by calamities; also, Brahmins, women, children, elders, the handicapped, the unemployed, the ill, and the insane were all perpetually exempted. The collectors were mandated to be Muslims. A majority of modern scholars reject that religious bigotry influenced the imposition; rather, realpolitik – economic constraints as a result of multiple ongoing battles and establishment of credence with the orthodox Ulemas – are held to be primary agents. Aurangzeb also enforced a higher tax burden on Hindu merchants at the rate of 5% (as against 2.5% on Muslim merchants), which led to considerable dislike of Aurangzeb's economic policies; a sharp turn from Akbar's uniform tax code. According to Marc Jason Gilbert, Aurangzeb ordered the jizya fees to be paid in person, in front of a tax collector, where the non Muslims were to recite a verse in the Quran which referred to their inferior status as non Muslims. This decision led to protests and lamentations among the masses as well as Hindu court officials. In order to meet state expenditures, Aurangzeb had ordered increases in land taxes; the burden of which fell heavily upon the Hindu Jats. The reimposition of the jizya encouraged Hindus to flee to areas under East India Company jurisdiction, under which policies of religious sufferance and pretermissions of religious taxes prevailed. Policy on temples and mosques Aurangzeb issued land grants and provided funds for the maintenance of shrines of worship but also (often) ordered their destruction. Modern historians reject the thought-school of colonial and nationalist historians about these destruction being guided by religious zealotry; rather, the association of temples with sovereignty, power and authority is emphasized upon. Whilst constructing mosques were considered an act of royal duty to subjects, there are also several firmans in Aurangzeb's name, supporting temples, maths, chishti shrines, and gurudwaras, including Mahakaleshwar temple of Ujjain, a gurudwara at Dehradun, Balaji temple of Chitrakoot, Umananda Temple of Guwahati and the Shatrunjaya Jain temples, among others. Numerous new temples were built, as well. Contemporary court-chronicles mention hundreds of temple which were demolished by Aurangzab or his chieftains, upon his order. In September 1669, he ordered the destruction of Vishvanath Temple at Varanasi, which was established by Raja Man Singh, whose grandson Jai Singh was believed to have facilitated Shivaji's escape. After the Jat rebellion in Mathura (early 1670), which killed the patron of the town-mosque, Aurangzeb suppressed the rebels and ordered for the city's Kesava Deo temple to be demolished, and replaced with an Eidgah. In 1672–73, Aurangzeb ordered the resumption of all grants held by Hindus throughout the empire, though this was not followed absolutely in regions such as Gujarat, where lands granted in in'am to Charans were not affected. In around 1679, he ordered destruction of several prominent temples, including those of Khandela, Udaipur, Chittor and Jodhpur, which were patronaged by rebels. The Jama Masjid at Golkunda was similarly treated, after it was found that its ruler had built it to hide revenues from the state; however desecration of mosques are rare due to their complete lack of political capital contra temples. In an order specific to Benaras, Aurangzeb invokes Sharia to declare that Hindus will be granted state-protection and temples won't be razed (but prohibits construction of any new temple); other orders to similar effect can be located. Richard Eaton, upon a critical evaluation of primary sources, counts 15 temples to have been destroyed during Aurangzeb's reign. Ian Copland and others reiterate Iqtidar Alam Khan who notes that, overall, Aurangzeb built more temples than he destroyed. Execution of opponents In 1689, the second Maratha Chhatrapati (King) Sambhaji was executed by Aurangzeb. In a sham trial, he was found guilty of murder and violence, atrocities against the Muslims of Burhanpur and Bahadurpur in Berar by Marathas under his command. In 1675 the Sikh leader Guru Tegh Bahadur was arrested on orders by Aurangzeb, found guilty of blasphemy by a Qadi's court and executed. The 32nd Da'i al-Mutlaq (Absolute Missionary) of the Dawoodi Bohra sect of Musta'lī Islam Syedna Qutubkhan Qutubuddin was executed by Aurangzeb, then governor of Gujarat, for heresy; on 27 Jumadil Akhir 1056 AH (1648 AD), Ahmedabad, India. Expansion of the Mughal Empire In 1663, during his visit to Ladakh, Aurangzeb established direct control over that part of the empire and loyal subjects such as Deldan Namgyal agreed to pledge tribute and loyalty. Deldan Namgyal is also known to have constructed a Grand Mosque in Leh, which he dedicated to Mughal rule. In 1664, Aurangzeb appointed Shaista Khan subedar (governor) of Bengal. Shaista Khan eliminated Portuguese and Arakanese pirates from the region, and in 1666 recaptured the port of Chittagong from the Arakanese king, Sanda Thudhamma. Chittagong remained a key port throughout Mughal rule. In 1685, Aurangzeb dispatched his son, Muhammad Azam Shah, with a force of nearly 50,000 men to capture Bijapur Fort and defeat Sikandar Adil Shah (the ruler of Bijapur) who refused to be a vassal. The Mughals could not make any advancements upon Bijapur Fort, mainly because of the superior usage of cannon batteries on both sides. Outraged by the stalemate Aurangzeb himself arrived on 4 September 1686 and commanded the siege of Bijapur; after eight days of fighting, the Mughals were victorious. Only one remaining ruler, Abul Hasan Qutb Shah (the Qutbshahi ruler of Golconda), refused to surrender. He and his servicemen fortified themselves at Golconda and fiercely protected the Kollur Mine, which was then probably the world's most productive diamond mine, and an important economic asset. In 1687, Aurangzeb led his grand Mughal army against the Deccan Qutbshahi fortress during the siege of Golconda. The Qutbshahis had constructed massive fortifications throughout successive generations on a granite hill over 400 ft high with an enormous eight-mile long wall enclosing the city. The main gates of Golconda had the ability to repulse any war elephant attack. Although the Qutbshahis maintained the impregnability of their walls, at night Aurangzeb and his infantry erected complex scaffolding that allowed them to scale the high walls. During the eight-month siege the Mughals faced many hardships including the death of their experienced commander Kilich Khan Bahadur. Eventually, Aurangzeb and his forces managed to penetrate the walls by capturing a gate, and their entry into the fort led Abul Hasan Qutb Shah to surrender peacefully. Military equipment Mughal cannon making skills advanced during the 17th century. One of the most impressive Mughal cannons is known as the Zafarbaksh, which is a very rare composite cannon, that required skills in both wrought-iron forge welding and bronze-casting technologies and the in-depth knowledge of the qualities of both metals. The Ibrahim Rauza was a famed cannon, which was well known for its multi-barrels. François Bernier, the personal physician to Aurangzeb, observed Mughal gun-carriages each drawn by two horses, an improvement over the bullock-drawn gun-carriages used elsewhere in India. Despite these innovations, most soldiers used bows and arrows, the quality of sword manufacture was so poor that they preferred to use ones imported from England, and the operation of the cannons was entrusted not to Mughals but to European gunners. Other weapons used during the period included rockets, cauldrons of boiling oil, muskets and manjaniqs (stone-throwing catapults). War elephants In 1703, the Mughal commander at Coromandel, Daud Khan Panni spent 10,500 coins to purchase 30 to 50 war elephants from Ceylon. Art and culture Aurangzeb was noted for his religious piety; he memorized the entire Quran, studied hadiths and stringently observed the rituals of Islam, and "transcribe[d] copies of the Quran." Aurangzeb had a more austere nature than his predecessors, and greatly reduced imperial patronage of the figurative Mughal miniature. This had the effect of dispersing the court atelier to other regional courts. Being religious he encouraged Islamic calligraphy. His reign also saw the building of the Lahore Badshahi Masjid and Bibi Ka Maqbara in Aurangabad for his wife Rabia-ud-Daurani. Aurangzeb was considered a Mujaddid by contemporary Muslims considered Aurangzeb. Calligraphy The Mughal Emperor Aurangzeb is known to have patronised works of Islamic calligraphy; the demand for Quran manuscripts in the naskh style peaked during his reign. Having been instructed by Syed Ali Tabrizi, Aurangzeb was himself a talented calligrapher in naskh, evidenced by Quran manuscripts that he created. Architecture Aurangzeb was not as involved in architecture as his father. Under Aurangzeb's rule, the position of the Mughal Emperor as chief architectural patron began to diminish. However, Aurangzeb did endow some significant structures. Catherine Asher terms his architectural period as an "Islamization" of Mughal architecture. One of the earliest constructions after his accession was a small marble mosque known as the Moti Masjid (Pearl Mosque), built for his personal use in the Red Fort complex of Delhi. He later ordered the construction of the Badshahi Mosque in Lahore, which is today one of the largest mosques in the Indian subcontinent. The mosque he constructed in Srinagar is still the largest in Kashmir. Most of Aurangzeb's building activity revolved around mosques, but secular structures were not neglected. The Bibi Ka Maqbara in Aurangabad, the mausoleum of Rabia-ud-Daurani, was constructed by his eldest son Azam Shah upon Aurangzeb's decree. Its architecture displays clear inspiration from the Taj Mahal. Aurangzeb also provided and repaired urban structures like fortifications (for example a wall around Aurangabad, many of whose gates still survive), bridges, caravanserais, and gardens. Aurangzeb was more heavily involved in the repair and maintenance of previously existing structures. The most important of these were mosques, both Mughal and pre-Mughal, which he repaired more of than any of his predecessors. He patronised the dargahs of Sufi saints such as Bakhtiyar Kaki, and strived to maintain royal tombs. Textiles The textile industry in the Mughal Empire emerged very firmly during the reign of the Mughal Emperor Aurangzeb and was particularly well noted by Francois Bernier, a French physician of the Mughal Emperor. Francois Bernier writes how Karkanahs, or workshops for the artisans, particularly in textiles flourished by "employing hundreds of embroiderers, who were superintended by a master". He further writes how "Artisans manufacture of silk, fine brocade, and other fine muslins, of which are made turbans, robes of gold flowers, and tunics worn by females, so delicately fine as to wear out in one night, and cost even more if they were well embroidered with fine needlework". He also explains the different techniques employed to produce such complicated textiles such as Himru (whose name is Persian for "brocade"), Paithani (whose pattern is identical on both sides), Mushru (satin weave) and how Kalamkari, in which fabrics are painted or block-printed, was a technique that originally came from Persia. Francois Bernier provided some of the first, impressive descriptions of the designs and the soft, delicate texture of Pashmina shawls also known as Kani, which were very valued for their warmth and comfort among the Mughals, and how these textiles and shawls eventually began to find their way to France and England. Foreign relations Aurangzeb sent diplomatic missions to Mecca in 1659 and 1662, with money and gifts for the Sharif. He also sent alms in 1666 and 1672 to be distributed in Mecca and Medina. Historian Naimur Rahman Farooqi writes that, "By 1694, Aurangzeb's ardour for the Sharifs of Mecca had begun to wane; their greed and rapacity had thoroughly disillusioned the Emperor ... Aurangzeb expressed his disgust at the unethical behavior of the Sharif who appropriated all the money sent to the Hijaz for his own use, thus depriving the needy and the poor." Relations with the Uzbek Subhan Quli Khan, Balkh's Uzbek ruler was the first to recognise him in 1658 and requested for a general alliance, he worked alongside the new Mughal Emperor since 1647, when Aurangzeb was the Subedar of Balkh. Relations with the Safavid dynasty Aurangzeb received the embassy of Abbas II of Persia in 1660 and returned them with gifts. However, relations between the Mughal Empire and the Safavid dynasty were tense because the Persians attacked the Mughal army positioned near Kandahar. Aurangzeb prepared his armies in the Indus River Basin for a counteroffensive, but Abbas II's death in 1666 caused Aurangzeb to end all hostilities. Aurangzeb's rebellious son, Sultan Muhammad Akbar, sought refuge with Suleiman I of Persia, who had rescued him from the Imam of Musqat and later refused to assist him in any military adventures against Aurangzeb. Relations with the French In 1667, the French East India Company ambassadors Le Gouz and Bebert presented Louis XIV of France's letter which urged the protection of French merchants from various rebels in the Deccan. In response to the letter, Aurangzeb issued a firman allowing the French to open a factory in Surat. Relations with the Sultanate of Maldives In the 1660s, the Sultan of the Maldives, Ibrahim Iskandar I, requested help from Aurangzeb's representative, the Faujdar of Balasore. The Sultan wished to gain his support in possible future expulsions of Dutch and English trading ships, as he was concerned with how they might impact the economy of the Maldives. However, as Aurangzeb did not possess a powerful navy and had no interest in providing support to Ibrahim in a possible future war with the Dutch or English, the request came to nothing. Relations with the Ottoman Empire Like his father, Aurangzeb was not willing to acknowledge the Ottoman claim to the caliphate. He often supported the Ottoman Empire's enemies, extending cordial welcome to two rebel Governors of Basra, and granting them and their families a high status in the imperial service. Sultan Suleiman II's friendly postures were ignored by Aurangzeb. The Sultan urged Aurangzeb to wage holy war against Christians. Relations with the English and the Anglo-Mughal War In 1686, the East India Company, which had unsuccessfully tried to obtain a firman that would grant them regular trading privileges throughout the Mughal Empire, initiated the Anglo-Mughal War. This war ended in disaster for the English after Aurangzeb in 1689 dispatched a large fleet from Janjira that blockaded Bombay. The ships, commanded by Sidi Yaqub, were manned by Indians and Mappilas. In 1690, realising the war was not going favourably for them, the Company sent envoys to Aurangzeb's camp to plead for a pardon. The company's envoys prostrated themselves before the emperor, agreed pay a large indemnity, and promise to refrain from such actions in the future. In September 1695, English pirate Henry Every conducted one of the most profitable pirate raids in history with his capture of a Grand Mughal grab convoy near Surat. The Indian ships had been returning home from their annual pilgrimage to Mecca when the pirate struck, capturing the Ganj-i-Sawai, reportedly the largest ship in the Muslim fleet, and its escorts in the process. When news of the capture reached the mainland, a livid Aurangzeb nearly ordered an armed attack against the English-governed city of Bombay, though he finally agreed to compromise after the Company promised to pay financial reparations, estimated at £600,000 by the Mughal authorities. Meanwhile, Aurangzeb shut down four of the English East India Company's factories, imprisoned the workers and captains (who were nearly lynched by a rioting mob), and threatened to put an end to all English trading in India until Every was captured. The Lords Justices of England offered a bounty for Every's apprehension, leading to the first worldwide manhunt in recorded history. However, Every successfully eluded capture. In 1702, Aurangzeb sent Daud Khan Panni, the Mughal Empire's Subhedar of the Carnatic region, to besiege and blockade Fort St. George for more than three months. The governor of the fort Thomas Pitt was instructed by the East India Company to sue for peace. Relations with the Ethiopian Empire Ethiopian Emperor Fasilides dispatched an embassy to India in 1664–65 to congratulate Aurangzeb upon his accession to the throne of the Mughal Empire. Relations with the Tibetans, Uyghurs, and Dzungars After 1679, the Tibetans invaded Ladakh, which was in the Mughal sphere of influence. Aurangzeb intervened on Ladakh's behalf in 1683, but his troops retreated before Dzungar reinforcements arrived to bolster the Tibetan position. At the same time, however, a letter was sent from the governor of Kashmir claiming the Mughals had defeated the Dalai Lama and conquered all of Tibet, a cause for celebration in Aurangzeb's court. Aurangzeb received an embassy from Muhammad Amin Khan of Chagatai Moghulistan in 1690, seeking assistance in driving out "Qirkhiz infidels" (meaning the Buddhist Dzungars), who "had acquired dominance over the country". Relations with the Czardom of Russia Russian Czar Peter the Great requested Aurangzeb to open Russo-Mughal trade relations in the late 17th century. In 1696 Aurangzeb received his envoy, Semyon Malenkiy, and allowed him to conduct free trade. After staying for six years in India, and visiting Surat, Burhanpur, Agra, Delhi and other cities, Russian merchants returned to Moscow with valuable Indian goods. Administrative reforms Tribute Aurangzeb received tribute from all over the Indian subcontinent, using this wealth to establish bases and fortifications in India, particularly in the Carnatic, Deccan, Bengal and Lahore. Revenue Aurangzeb's exchequer raised a record £100 million in annual revenue through various sources like taxes, customs and land revenue, et al. from 24 provinces. He had an annual yearly revenue of $450 million, more than ten times that of his contemporary Louis XIV of France. Coins Aurangzeb felt that verses from the Quran should not be stamped on coins, as done in former times, because they were constantly touched by the hands and feet of people. His coins had the name of the mint city and the year of issue on one face, and, the following couplet on other: Rebellions Traditional and newly coherent social groups in northern and western India, such as the Marathas, Rajputs, Hindu Jats, Pashtuns, and Sikhs, gained military and governing ambitions during Mughal rule, which, through collaboration or opposition, gave them both recognition and military experience. In 1669, the Hindu Jat peasants of Bharatpur around Mathura rebelled and created Bharatpur State but were defeated. In 1659, Maratha Emperor Shivaji, launched a surprise attack on the Mughal Viceroy Shaista Khan and, while waging war against Aurangzeb. Shivaji and his forces attacked the Deccan, Janjira and Surat and tried to gain control of vast territories. In 1689, Aurangzeb's armies captured Shivaji's son Sambhaji and executed him. But the Marathas continued the fight. In 1679, the Rathore clan under the command of Durgadas Rathore of Marwar rebelled when Aurangzeb did not give permission to make the young Rathore prince the king and took direct command of Jodhpur. This incident caused great unrest among the Hindu Rajput rulers under Aurangzeb and led to many rebellions in Rajputana, resulting in the loss of Mughal power in the region and religious bitterness over the destruction of temples. In 1672, the Satnami, a sect concentrated in an area near Delhi, under the leadership of Bhirbhan, took over the administration of Narnaul, but they were eventually crushed upon Aurangzeb's personal intervention with very few escaping alive. In 1671, the battle of Saraighat was fought in the easternmost regions of the Mughal Empire against the Ahom Kingdom. The Mughals led by Mir Jumla II and Shaista Khan attacked and were defeated by the Ahoms. Maharaja Chhatrasal was the a warrior from Bundela Rajput clan, who fought against the Mughal Emperor Aurangzeb, and established his own kingdom in Bundelkhand, becoming a Maharaja of Panna. Jat rebellion In 1669, Hindu Jats began to organise a rebellion that is believed to have been caused by the re-imposition of jizya and destruction of Hindu temples in Mathura. The Jats were led by Gokula, a rebel landholder from Tilpat. By the year 1670 20,000 Jat rebels were quelled and the Mughal Army took control of Tilpat, Gokula's personal fortune amounted to 93,000 gold coins and hundreds of thousands of silver coins. Gokula was caught and executed. But the Jats once again attempted rebellion. Raja Ram Jat, in order to avenge his father Gokula's death, plundered Akbar's tomb of its gold, silver and fine carpets, opened Akbar's grave and dragged his bones and burned them in retaliation. Jats also shot off the tops of the minarets on the gateway to Akbar's Tomb and melted down two silver doors from the Taj Mahal. Aurangzeb appointed Mohammad Bidar Bakht as commander to crush the Jat rebellion. On 4 July 1688, Raja Ram Jat was captured and beheaded. His head was sent to Aurangzeb as proof. However, after Aurangeb's death, Jats under Badan Singh later established their independent state of Bharatpur. Due to the Jat rebellion, the temples of Pushtimarg, Gaudiya, and Radha vallabh Vaishnavs in Braj were abandoned and their icons were taken to different regions or into hiding. Mughal–Maratha Wars In 1657, while Aurangzeb attacked Golconda and Bijapur in the Deccan, the Hindu Maratha warrior, Shivaji, used guerrilla tactics to take control of three Adil Shahi forts formerly under his father's command. With these victories, Shivaji assumed de facto leadership of many independent Maratha clans. The Marathas harried the flanks of the warring Adil Shahis, gaining weapons, forts, and territory. Shivaji's small and ill-equipped army survived an all out Adil Shahi attack, and Shivaji personally killed the Adil Shahi general, Afzal Khan. With this event, the Marathas transformed into a powerful military force, capturing more and more Adil Shahi territories. Shivaji went on to neutralise Mughal power in the region. In 1659, Aurangzeb sent his trusted general and maternal uncle Shaista Khan, the Wali in Golconda to recover forts lost to the Maratha rebels. Shaista Khan drove into Maratha territory and took up residence in Pune. But in a daring raid on the governor's palace in Pune during a midnight wedding celebration, led by Shivaji himself, the Marathas killed Shaista Khan's son and Shivaji maimed Shaista Khan by cutting off three fingers of his hand. Shaista Khan, however, survived and was re-appointed the administrator of Bengal going on to become a key commander in the war against the Ahoms. Aurangzeb next sent general Raja Jai Singh to vanquish the Marathas. Jai Singh besieged the fort of Purandar and fought off all attempts to relieve it. Foreseeing defeat, Shivaji agreed to terms. Jai Singh persuaded Shivaji to visit Aurangzeb at Agra, giving him a personal guarantee of safety. Their meeting at the Mughal court did not go well, however. Shivaji felt slighted at the way he was received, and insulted Aurangzeb by refusing imperial service. For this affront he was detained, but managed to effect a daring escape. Shivaji returned to the Deccan, and crowned himself Chhatrapati or the ruler of the Maratha Kingdom in 1674. Shivaji expanded Maratha control throughout the Deccan until his death in 1680. Shivaji was succeeded by his son, Sambhaji. Militarily and politically, Mughal efforts to control the Deccan continued to fail. On the other hand, Aurangzeb's third son Akbar left the Mughal court along with a few Muslim Mansabdar supporters and joined Muslim rebels in the Deccan. Aurangzeb in response moved his court to Aurangabad and took over command of the Deccan campaign. The rebels were defeated and Akbar fled south to seek refuge with Sambhaji, Shivaji's successor. More battles ensued, and Akbar fled to Persia and never returned. In 1689, Aurangzeb's forces captured and executed Sambhaji. His successor Rajaram, later Rajaram's widow Tarabai and their Maratha forces fought individual battles against the forces of the Mughal Empire. Territory changed hands repeatedly during the years (1689–1707) of interminable warfare. As there was no central authority among the Marathas, Aurangzeb was forced to contest every inch of territory, at great cost in lives and money. Even as Aurangzeb drove west, deep into Maratha territory – notably conquering Satara – the Marathas expanded eastwards into Mughal lands – Malwa and Hyderabad. The Marathas also expanded further South into Southern India defeating the independent local rulers there capturing Jinji in Tamil Nadu. Aurangzeb waged continuous war in the Deccan for more than two decades with no resolution. He thus lost about a fifth of his army fighting rebellions led by the Marathas in Deccan India. He travelled a long distance to the Deccan to conquer the Marathas and eventually died at the age of 88, still fighting the Marathas. Aurangzeb's shift from conventional warfare to anti-insurgency in the Deccan region shifted the paradigm of Mughal military thought. There were conflicts between Marathas and Mughals in Pune, Jinji, Malwa and Vadodara. The Mughal Empire's port city of Surat was sacked twice by the Marathas during the reign of Aurangzeb and the valuable port was in ruins. Matthew White estimates that about 2.5 million of Aurangzeb's army were killed during the Mughal–Maratha Wars (100,000 annually during a quarter-century), while 2 million civilians in war-torn lands died due to drought, plague and famine. Ahom campaign While Aurangzeb and his brother Shah Shuja had been fighting against each other, the Hindu rulers of Kuch Behar and Assam took advantage of the disturbed conditions in the Mughal Empire, had invaded imperial dominions. For three years they were not attacked, but in 1660 Mir Jumla II, the viceroy of Bengal, was ordered to recover the lost territories. The Mughals set out in November 1661. Within weeks they occupied the capital of Kuch Behar, which they annexed. Leaving a detachment to garrison it, the Mughal army began to retake their territories in Assam. Mir Jumla II advanced on Garhgaon, the capital of the Ahom kingdom, and reached it on 17 March 1662. The ruler, Raja Sutamla, had fled before his approach. The Mughals captured 82 elephants, 300,000 rupees in cash, 1000 ships, and 173 stores of rice. On his way back to Dacca, in March 1663, Mir Jumla II died of natural causes. Skirmishes continued between the Mughals and Ahoms after the rise of Chakradhwaj Singha, who refused to pay further indemnity to the Mughals and during the wars that continued the Mughals suffered great hardships. Munnawar Khan emerged as a leading figure and is known to have supplied food to vulnerable Mughal forces in the region near Mathurapur. Although the Mughals under the command of Syed Firoz Khan the Faujdar at Guwahati were overrun by two Ahom armies in 1667, but they continued to hold and maintain presence in their eastern territories even after the battle of Saraighat in 1671. The battle of Saraighat was fought in 1671 between the Mughal empire (led by the Kachwaha king, Raja Ramsingh I), and the Ahom Kingdom (led by Lachit Borphukan) on the Brahmaputra river at Saraighat, now in Guwahati. Although much weaker, the Ahom Army defeated the Mughal Army by brilliant uses of the terrain, clever diplomatic negotiations to buy time, guerrilla tactics, psychological warfare, military intelligence and by exploiting the sole weakness of the Mughal forcesits navy. The battle of Saraighat was the last battle in the last major attempt by the Mughals to extend their empire into Assam. Though the Mughals managed to regain Guwahati briefly after a later Borphukan deserted it, the Ahoms wrested control in the battle of Itakhuli in 1682 and maintained it till the end of their rule. Satnami opposition In May 1672, the Satnami sect obeying the commandments of an "old toothless woman" (according to Mughal accounts) organised a massive revolt in the agricultural heartlands of the Mughal Empire. The Satnamis were known to have shaved off their heads and even eyebrows and had temples in many regions of Northern India. They began a large-scale rebellion 75 miles southwest of Delhi. The Satnamis believed they were invulnerable to Mughal bullets and believed they could multiply in any region they entered. The Satnamis initiated their march upon Delhi and overran small-scale Mughal infantry units. Aurangzeb responded by organising a Mughal army of 10,000 troops and artillery, and dispatched detachments of his own personal Mughal imperial guards to carry out several tasks. To boost Mughal morale, Aurangzeb wrote Islamic prayers, made amulets, and drew designs that would become emblems in the Mughal Army. This rebellion would have a serious aftermath effect on the Punjab. Sikh opposition The ninth Sikh Guru, Guru Tegh Bahadur, like his predecessors was opposed to forced conversion of the local population as he considered it wrong. Approached by Kashmiri Pandits to help them retain their faith and avoid forced religious conversions, Guru Tegh Bahadur sent a message to the emperor that if he could convert Teg Bagadur to Islam, every Hindu will become a Muslim. In response, Aurangzeb ordered arrest of the Guru. He was then brought to Delhi and tortured so as to convert him. On his refusal to convert, he was beheaded in 1675. In response, Guru Tegh Bahadur's son and successor, Guru Gobind Singh, further militarised his followers, starting with the establishment of Khalsa in 1699, eight years before Aurangzeb's death. In 1705, Guru Gobind Singh sent a letter entitled Zafarnamah, which accused Aurangzeb of cruelty and betraying Islam. The letter caused him much distress and remorse. Guru Gobind Singh's formation of Khalsa in 1699 led to the establishment of the Sikh Confederacy and later Sikh Empire. Pashtun opposition The Pashtun revolt in 1672 under the leadership of the warrior poet Khushal Khan Khattak of Kabul, was triggered when soldiers under the orders of the Mughal Governor Amir Khan allegedly molested women of the Pashtun tribes in modern-day Kunar Province of Afghanistan. The Safi tribes retaliated against the soldiers. This attack provoked a reprisal, which triggered a general revolt of most of tribes. Attempting to reassert his authority, Amir Khan led a large Mughal Army to the Khyber Pass, where the army was surrounded by tribesmen and routed, with only four men, including the Governor, managing to escape. Aurangzeb's incursions into the Pashtun areas were described by Khushal Khan Khattak as "Black is the Mughal's heart towards all of us Pathans". Aurangzeb employed the scorched earth policy, sending soldiers who massacred, looted and burnt many villages. Aurangzeb also proceeded to use bribery to turn the Pashtun tribes against each other, with the aim that they would distract a unified Pashtun challenge to Mughal authority, and the impact of this was to leave a lasting legacy of mistrust among the tribes. After that the revolt spread, with the Mughals suffering a near total collapse of their authority in the Pashtun belt. The closure of the important Attock-Kabul trade route along the Grand Trunk road was particularly disastrous. By 1674, the situation had deteriorated to a point where Aurangzeb camped at Attock to personally take charge. Switching to diplomacy and bribery along with force of arms, the Mughals eventually split the rebels and partially suppressed the revolt, although they never managed to wield effective authority outside the main trade route. Death By 1689, the conquest of Golconda, Mughal victories in the south expanded the Mughal Empire to 4 million square kilometres, with a population estimated to be over 158 million. But this supremacy was short-lived. Jos Gommans, Professor of Colonial and Global History at the University of Leiden, says that "... the highpoint of imperial centralisation under emperor Aurangzeb coincided with the start of the imperial downfall." Aurangzeb constructed a small marble mosque known as the Moti Masjid (Pearl Mosque) in the Red Fort complex in Delhi. However, his constant warfare, especially with the Marathas, drove his empire to the brink of bankruptcy just as much as the wasteful personal spending and opulence of his predecessors. The Indologist Stanley Wolpert, emeritus professor at UCLA, says that: Even when ill and dying, Aurangzeb made sure that the populace knew he was still alive, for if they had thought otherwise then the turmoil of another war of succession was likely. He died at his military camp in Bhingar near Ahmednagar on 3 March 1707 at the age of 88, having outlived many of his children. He had only 300 rupees with him which were later given to charity as per his instructions and he prior to his death requested not to spend extravagantly on his funeral but to keep it simple. His modest open-air grave in Khuldabad, Aurangabad, Maharashtra expresses his deep devotion to his Islamic beliefs. It is sited in the courtyard of the shrine of the Sufi saint Shaikh Burhan-u'd-din Gharib, who was a disciple of Nizamuddin Auliya of Delhi. Brown writes that after his death, "a string of weak emperors, wars of succession, and coups by noblemen heralded the irrevocable weakening of Mughal power". She notes that the populist but "fairly old-fashioned" explanation for the decline is that there was a reaction to Aurangzeb's oppression. Although Aurangzeb died without appointing a successor, he instructed his three sons to divide the empire among themselves. His sons failed to reach a satisfactory agreement and fought against each other in a war of succession. Aurangzeb's immediate successor was his third son Azam Shah, who was defeated and killed in June 1707 at the battle of Jajau by the army of Bahadur Shah I, the second son of Aurangzeb. Both because of Aurangzeb's over-extension and because of Bahadur Shah's weak military and leadership qualities, entered a period of terminal decline. Immediately after Bahadur Shah occupied the throne, the Maratha Empire – which Aurangzeb had held at bay, inflicting high human and monetary costs even on his own empire – consolidated and launched effective invasions of Mughal territory, seizing power from the weak emperor. Within decades of Aurangzeb's death, the Mughal Emperor had little power beyond the walls of Delhi. Assessments and legacy Aurangzeb's rule has been the subject of both praise and controversy. During his lifetime, victories in the south expanded the Mughal Empire to 4 million square kilometres, and he ruled over a population estimated to be over 158 million subjects. His critics argue that his ruthlessness and religious bigotry made him unsuitable to rule the mixed population of his empire. Some critics assert that the persecution of Shias, Sufis and non-Muslims to impose practices of orthodox Islamic state, such as imposition of sharia and jizya religious tax on non-Muslims, doubling of custom duties on Hindus while abolishing it for Muslims, executions of Muslims and non-Muslims alike, and destruction of temples eventually led to numerous rebellions. G. N. Moin Shakir and Sarma Festschrift argue that he often used political opposition as pretext for religious persecution, and that, as a result, groups of Jats, Marathas, Sikhs, Satnamis and Pashtuns rose against him. Multiple interpretations of Aurangzeb's life and reign over the years by critics have led to a very complicated legacy. Some argue that his policies abandoned his predecessors' legacy of pluralism and religious tolerance, citing his introduction of the jizya tax and other policies based on Islamic ethics; his demolition of Hindu temples; the executions of his elder brother Dara Shikoh, King Sambhaji of Maratha and Sikh Guru Tegh Bahadur and the prohibition and supervision of behaviour and activities that are forbidden in Islam such as gambling, fornication, and consumption of alcohol and narcotics. At the same time, some historians question the historical authenticity of the claims of his critics, arguing that his destruction of temples has been exaggerated, and noting that he built more temples than he destroyed, paid for their maintenance, employed significantly more Hindus in his imperial bureaucracy than his predecessors, and opposed bigotry against Hindus and Shia Muslims. Muhammad Al-Munajjid has compilled that the opinions from Islamic scholarly community towards Aurangzeb were positive for the emperor general attitude such as abolished Bid'ah celebrations, musics, and also abolished the customs of bowing and kissing the ground which were done by his predecessors, practically adhering practice of Salafi while still held to Hanafite creed. In Pakistan, author Haroon Khalid writes that, "Aurangzeb is presented as a hero who fought and expanded the frontiers of the Islamic empire" and "is imagined to be a true believer who removed corrupt practices from religion and the court, and once again purified the empire." The academic Munis Faruqui also opines that the "Pakistani state and its allies in the religious and political establishments include him in the pantheon of premodern Muslim heroes, especially lauding him for his militarism, personal piety, and seeming willingness to accommodate Islamic morality within state goals." Muhammad Iqbal, considered the spiritual founder of Pakistan, compared him favorably to the prophet Abraham for his warfare against Akbar's Din-i Ilahi and idolatry, while Iqbal Singh Sevea, in his book on the political philosophy of the thinker, says that "Iqbal considered that the life and activities of Aurangzeb constituted the starting point of Muslim nationality in India." Maulana Shabbir Ahmad Usmani, in his funeral oration, hailed M.A. Jinnah, the founder of Pakistan, to be the greatest Muslim since Aurangzeb. Pakistani-American academic Akbar Ahmed described President Zia-ul-Haq, known for his Islamization drive, as "conceptually ... a spiritual descendent of Aurangzeb" because Zia had an orthodox, legalistic view of Islam. Beyond the individual appreciations, Aurangzeb is seminal to Pakistan's national self-consciousness, as historian Ayesha Jalal, while referring to the Pakistani textbooks controversy, mentions M. D. Zafar's A Text Book of Pakistan Studies where we can read that, under Aurangzeb, "Pakistan spirit gathered in strength", while his death "weakened the Pakistan spirit." Another historian from Pakistan, Mubarak Ali, also looking at the textbooks, and while noting that Akbar "is conveniently ignored and not mentioned in any school textbook from class one to matriculation", contrasts him with Aurangzeb, who "appears in different textbooks of Social Studies and Urdu language as an orthodox and pious Muslim copying the Holy Quran and sewing caps for his livelihood." This image of Aurangzeb is not limited to Pakistan's official historiography. As of 2015, about 177 towns and villages of India have been named after Aurangzeb. Historian Audrey Truschke points out that Bharatiya Janta Party (BJP), Hindutva proponents and some others outside Hindutva ideology regard Aurangzeb as Muslim zealot in India. Jawaharlal Nehru wrote that, due to his reversal of the cultural and religious syncretism of the previous Mughal emperors, Aurangzeb acted "more as a Moslem than an Indian ruler", while Mahatma Gandhi was of the view that there was greater degree of freedom under Mughal rule than the British rule and asks that "in Aurangzeb's time a Shivaji could flourish. Has one hundred and fifty years of the British rule produced any Pratap and Shivaji?" Full title The epithet Aurangzeb means 'Ornament of the Throne'. His chosen title Alamgir translates to Conqueror of the World. Aurangzeb's full imperial title was: Al-Sultan al-Azam wal Khaqan al-Mukarram Hazrat Abul Muzaffar Muhy-ud-Din Muhammad Aurangzeb Bahadur Alamgir I, Badshah Ghazi, Shahanshah-e-Sultanat-ul-Hindiya Wal Mughaliya. Aurangzeb had also been attributed various other titles including Caliph of The Merciful, Monarch of Islam, and Living Custodian of God.

An analog computer or analogue computer is a type of computer that uses the continuous variation aspect of physical phenomena such as electrical, mechanical, or hydraulic quantities (analog signals) to model the problem being solved. In contrast, digital computers represent varying quantities symbolically and by discrete values of both time and amplitude (digital signals). Analog computers can have a very wide range of complexity. Slide rules and nomograms are the simplest, while naval gunfire control computers and large hybrid digital/analog computers were among the most complicated. Complex mechanisms for process control and protective relays used analog computation to perform control and protective functions. Analog computers were widely used in scientific and industrial applications even after the advent of digital computers, because at the time they were typically much faster, but they started to become obsolete as early as the 1950s and 1960s, although they remained in use in some specific applications, such as aircraft flight simulators, the flight computer in aircraft, and for teaching control systems in universities. Perhaps the most relatable example of analog computers are mechanical watches where the continuous and periodic rotation of interlinked gears drives the second, minute and hour needles in the clock. More complex applications, such as aircraft flight simulators and synthetic-aperture radar, remained the domain of analog computing (and hybrid computing) well into the 1980s, since digital computers were insufficient for the task. Timeline of analog computers Precursors This is a list of examples of early computation devices considered precursors of the modern computers. Some of them may even have been dubbed 'computers' by the press, though they may fail to fit modern definitions. The Antikythera mechanism, a type of device used to determine the positions of heavenly bodies known as an orrery, was described as an early mechanical analog computer by British physicist, information scientist, and historian of science Derek J. de Solla Price. It was discovered in 1901, in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to , during the Hellenistic period. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later. Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. The planisphere was first described by Ptolemy in the 2nd century AD. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BC and is often attributed to Hipparchus. A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer and gear-wheels was invented by Abi Bakr of Isfahan, Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed-wired knowledge processing machine with a gear train and gear-wheels, . The sector, a calculating instrument used for solving problems in proportion, trigonometry, multiplication and division, and for various functions, such as squares and cube roots, was developed in the late 16th century and found application in gunnery, surveying and navigation. The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. The slide rule was invented around 1620–1630, shortly after the publication of the concept of the logarithm. It is a hand-operated analog computer for doing multiplication and division. As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions. Aviation is one of the few fields where slide rules are still in widespread use, particularly for solving time–distance problems in light aircraft. In 1831–1835, mathematician and engineer Giovanni Plana devised a perpetual-calendar machine, which, through a system of pulleys and cylinders, could predict the perpetual calendar for every year from AD 0 (that is, 1 BC) to AD 4000, keeping track of leap years and varying day length. The tide-predicting machine invented by Sir William Thomson in 1872 was of great utility to navigation in shallow waters. It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location. The differential analyser, a mechanical analog computer designed to solve differential equations by integration, used wheel-and-disc mechanisms to perform the integration. In 1876 James Thomson had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators. A number of similar systems followed, notably those of the Spanish engineer Leonardo Torres Quevedo, who built several machines for solving real and complex roots of polynomials; and Michelson and Stratton, whose Harmonic Analyser performed Fourier analysis, but using an array of 80 springs rather than Kelvin integrators. This work led to the mathematical understanding of the Gibbs phenomenon of overshoot in Fourier representation near discontinuities. In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in the 1920s, Vannevar Bush and others developed mechanical differential analyzers. Modern era The Dumaresq was a mechanical calculating device invented around 1902 by Lieutenant John Dumaresq of the Royal Navy. It was an analog computer that related vital variables of the fire control problem to the movement of one's own ship and that of a target ship. It was often used with other devices, such as a Vickers range clock to generate range and deflection data so the gun sights of the ship could be continuously set. A number of versions of the Dumaresq were produced of increasing complexity as development proceeded. By 1912, Arthur Pollen had developed an electrically driven mechanical analog computer for fire-control systems, based on the differential analyser. It was used by the Imperial Russian Navy in World War I. Starting in 1929, AC network analyzers were constructed to solve calculation problems related to electrical power systems that were too large to solve with numerical methods at the time. These were essentially scale models of the electrical properties of the full-size system. Since network analyzers could handle problems too large for analytic methods or hand computation, they were also used to solve problems in nuclear physics and in the design of structures. More than 50 large network analyzers were built by the end of the 1950s. World War II era gun directors, gun data computers, and bomb sights used mechanical analog computers. In 1942 Helmut Hölzer built a fully electronic analog computer at Peenemünde Army Research Center as an embedded control system (mixing device) to calculate V-2 rocket trajectories from the accelerations and orientations (measured by gyroscopes) and to stabilize and guide the missile. Mechanical analog computers were very important in gun fire control in World War II, the Korean War and well past the Vietnam War; they were made in significant numbers. In the period 1930–1945 in the Netherlands, Johan van Veen developed an analogue computer to calculate and predict tidal currents when the geometry of the channels are changed. Around 1950, this idea was developed into the Deltar, a hydraulic analogy computer supporting the closure of estuaries in the southwest of the Netherlands (the Delta Works). The FERMIAC was an analog computer invented by physicist Enrico Fermi in 1947 to aid in his studies of neutron transport. Project Cyclone was an analog computer developed by Reeves in 1950 for the analysis and design of dynamic systems. Project Typhoon was an analog computer developed by RCA in 1952. It consisted of over 4,000 electron tubes and used 100 dials and 6,000 plug-in connectors to program. The MONIAC Computer was a hydraulic analogy of a national economy first unveiled in 1949. Computer Engineering Associates was spun out of Caltech in 1950 to provide commercial services using the "Direct Analogy Electric Analog Computer" ("the largest and most impressive general-purpose analyzer facility for the solution of field problems") developed there by Gilbert D. McCann, Charles H. Wilts, and Bart Locanthi. Educational analog computers illustrated the principles of analog calculation. The Heathkit EC-1, a $199 educational analog computer, was made by the Heath Company, US . It was programmed using patch cords that connected nine operational amplifiers and other components. General Electric also marketed an "educational" analog computer kit of a simple design in the early 1960s consisting of two transistor tone generators and three potentiometers wired such that the frequency of the oscillator was nulled when the potentiometer dials were positioned by hand to satisfy an equation. The relative resistance of the potentiometer was then equivalent to the formula of the equation being solved. Multiplication or division could be performed, depending on which dials were inputs and which was the output. Accuracy and resolution was limited and a simple slide rule was more accurate. However, the unit did demonstrate the basic principle. Analog computer designs were published in electronics magazines. One example is the PEAC (Practical Electronics analogue computer), published in Practical Electronics in the January 1968 edition. Another more modern hybrid computer design was published in Everyday Practical Electronics in 2002. An example described in the EPE hybrid computer was the flight of a VTOL aircraft such as the Harrier jump jet. The altitude and speed of the aircraft were calculated by the analog part of the computer and sent to a PC via a digital microprocessor and displayed on the PC screen. In industrial process control, analog loop controllers were used to automatically regulate temperature, flow, pressure, or other process conditions. The technology of these controllers ranged from purely mechanical integrators, through vacuum-tube and solid-state devices, to emulation of analog controllers by microprocessors. Electronic analog computers The similarity between linear mechanical components, such as springs and dashpots (viscous-fluid dampers), and electrical components, such as capacitors, inductors, and resistors is striking in terms of mathematics. They can be modeled using equations of the same form. However, the difference between these systems is what makes analog computing useful. Complex systems often are not amenable to pen-and-paper analysis, and require some form of testing or simulation. Complex mechanical systems, such as suspensions for racing cars, are expensive to fabricate and hard to modify. And taking precise mechanical measurements during high-speed tests adds further difficulty. By contrast, it is very inexpensive to build an electrical equivalent of a complex mechanical system, to simulate its behavior. Engineers arrange a few operational amplifiers (op amps) and some passive linear components to form a circuit that follows the same equations as the mechanical system being simulated. All measurements can be taken directly with an oscilloscope. In the circuit, the (simulated) stiffness of the spring, for instance, can be changed by adjusting the parameters of an integrator. The electrical system is an analogy to the physical system, hence the name, but it is much less expensive than a mechanical prototype, much easier to modify, and generally safer. The electronic circuit can also be made to run faster or slower than the physical system being simulated. Experienced users of electronic analog computers said that they offered a comparatively intimate control and understanding of the problem, relative to digital simulations. Electronic analog computers are especially well-suited to representing situations described by differential equations. Historically, they were often used when a system of differential equations proved very difficult to solve by traditional means. As a simple example, the dynamics of a spring-mass system can be described by the equation , with as the vertical position of a mass , the damping coefficient, the spring constant and the gravity of Earth. For analog computing, the equation is programmed as . The equivalent analog circuit consists of two integrators for the state variables (speed) and (position), one inverter, and three potentiometers. Electronic analog computers have drawbacks: the value of the circuit's supply voltage limits the range over which the variables may vary (since the value of a variable is represented by a voltage on a particular wire). Therefore, each problem must be scaled so its parameters and dimensions can be represented using voltages that the circuit can supply —e.g., the expected magnitudes of the velocity and the position of a spring pendulum. Improperly scaled variables can have their values "clamped" by the limits of the supply voltage. Or if scaled too small, they can suffer from higher noise levels. Either problem can cause the circuit to produce an incorrect simulation of the physical system. (Modern digital simulations are much more robust to widely varying values of their variables, but are still not entirely immune to these concerns: floating-point digital calculations support a huge dynamic range, but can suffer from imprecision if tiny differences of huge values lead to numerical instability.) The precision of the analog computer readout was limited chiefly by the precision of the readout equipment used, generally three or four significant figures. (Modern digital simulations are much better in this area. Digital arbitrary-precision arithmetic can provide any desired degree of precision.) However, in most cases the precision of an analog computer is absolutely sufficient given the uncertainty of the model characteristics and its technical parameters. Many small computers dedicated to specific computations are still part of industrial regulation equipment, but from the 1950s to the 1970s, general-purpose analog computers were the only systems fast enough for real time simulation of dynamic systems, especially in the aircraft, military and aerospace field. In the 1960s, the major manufacturer was Electronic Associates of Princeton, New Jersey, with its 231R Analog Computer (vacuum tubes, 20 integrators) and subsequently its EAI 8800 Analog Computer (solid state operational amplifiers, 64 integrators). Its challenger was Applied Dynamics of Ann Arbor, Michigan. Although the basic technology for analog computers is usually operational amplifiers (also called "continuous current amplifiers" because they have no low frequency limitation), in the 1960s an attempt was made in the French ANALAC computer to use an alternative technology: medium frequency carrier and non dissipative reversible circuits. In the 1970s, every large company and administration concerned with problems in dynamics had an analog computing center, such as: In the US: NASA (Huntsville, Houston), Martin Marietta (Orlando), Lockheed, Westinghouse, Hughes Aircraft In Europe: CEA (French Atomic Energy Commission), MATRA, Aérospatiale, BAC (British Aircraft Corporation). Analog–digital hybrids Analog computing devices are fast; digital computing devices are more versatile and accurate. The idea behind an analog-digital hybrid is to combine the two processes for the best efficiency. An example of such hybrid elementary device is the hybrid multiplier, where one input is an analog signal, the other input is a digital signal and the output is analog. It acts as an analog potentiometer, upgradable digitally. This kind of hybrid technique is mainly used for fast dedicated real time computation when computing time is very critical, as signal processing for radars and generally for controllers in embedded systems. In the early 1970s, analog computer manufacturers tried to tie together their analog computers with a digital computers to get the advantages of the two techniques. In such systems, the digital computer controlled the analog computer, providing initial set-up, initiating multiple analog runs, and automatically feeding and collecting data. The digital computer may also participate to the calculation itself using analog-to-digital and digital-to-analog converters. The largest manufacturer of hybrid computers was Electronic Associates. Their hybrid computer model 8900 was made of a digital computer and one or more analog consoles. These systems were mainly dedicated to large projects such as the Apollo program and Space Shuttle at NASA, or Ariane in Europe, especially during the integration step where at the beginning everything is simulated, and progressively real components replace their simulated parts. Only one company was known as offering general commercial computing services on its hybrid computers, CISI of France, in the 1970s. The best reference in this field is the 100,000 simulation runs for each certification of the automatic landing systems of Airbus and Concorde aircraft. After 1980, purely digital computers progressed more and more rapidly and were fast enough to compete with analog computers. One key to the speed of analog computers was their fully parallel computation, but this was also a limitation. The more equations required for a problem, the more analog components were needed, even when the problem wasn't time critical. "Programming" a problem meant interconnecting the analog operators; even with a removable wiring panel this was not very versatile. Today there are no more big hybrid computers, but only hybrid components. Implementations Mechanical analog computers While a wide variety of mechanisms have been developed throughout history, some stand out because of their theoretical importance, or because they were manufactured in significant quantities. Most practical mechanical analog computers of any significant complexity used rotating shafts to carry variables from one mechanism to another. Cables and pulleys were used in a Fourier synthesizer, a tide-predicting machine, which summed the individual harmonic components. Another category, not nearly as well known, used rotating shafts only for input and output, with precision racks and pinions. The racks were connected to linkages that performed the computation. At least one U.S. Naval sonar fire control computer of the later 1950s, made by Librascope, was of this type, as was the principal computer in the Mk. 56 Gun Fire Control System. Online, there is a remarkably clear illustrated reference (OP 1140) that describes the fire control computer mechanisms. For adding and subtracting, precision miter-gear differentials were in common use in some computers; the Ford Instrument Mark I Fire Control Computer contained about 160 of them. Integration with respect to another variable was done by a rotating disc driven by one variable. Output came from a pick-off device (such as a wheel) positioned at a radius on the disc proportional to the second variable. (A carrier with a pair of steel balls supported by small rollers worked especially well. A roller, its axis parallel to the disc's surface, provided the output. It was held against the pair of balls by a spring.) Arbitrary functions of one variable were provided by cams, with gearing to convert follower movement to shaft rotation. Functions of two variables were provided by three-dimensional cams. In one good design, one of the variables rotated the cam. A hemispherical follower moved its carrier on a pivot axis parallel to that of the cam's rotating axis. Pivoting motion was the output. The second variable moved the follower along the axis of the cam. One practical application was ballistics in gunnery. Coordinate conversion from polar to rectangular was done by a mechanical resolver (called a "component solver" in US Navy fire control computers). Two discs on a common axis positioned a sliding block with pin (stubby shaft) on it. One disc was a face cam, and a follower on the block in the face cam's groove set the radius. The other disc, closer to the pin, contained a straight slot in which the block moved. The input angle rotated the latter disc (the face cam disc, for an unchanging radius, rotated with the other (angle) disc; a differential and a few gears did this correction). Referring to the mechanism's frame, the location of the pin corresponded to the tip of the vector represented by the angle and magnitude inputs. Mounted on that pin was a square block. Rectilinear-coordinate outputs (both sine and cosine, typically) came from two slotted plates, each slot fitting on the block just mentioned. The plates moved in straight lines, the movement of one plate at right angles to that of the other. The slots were at right angles to the direction of movement. Each plate, by itself, was like a Scotch yoke, known to steam engine enthusiasts. During World War II, a similar mechanism converted rectilinear to polar coordinates, but it was not particularly successful and was eliminated in a significant redesign (USN, Mk. 1 to Mk. 1A). Multiplication was done by mechanisms based on the geometry of similar right triangles. Using the trigonometric terms for a right triangle, specifically opposite, adjacent, and hypotenuse, the adjacent side was fixed by construction. One variable changed the magnitude of the opposite side. In many cases, this variable changed sign; the hypotenuse could coincide with the adjacent side (a zero input), or move beyond the adjacent side, representing a sign change. Typically, a pinion-operated rack moving parallel to the (trig.-defined) opposite side would position a slide with a slot coincident with the hypotenuse. A pivot on the rack let the slide's angle change freely. At the other end of the slide (the angle, in trig. terms), a block on a pin fixed to the frame defined the vertex between the hypotenuse and the adjacent side. At any distance along the adjacent side, a line perpendicular to it intersects the hypotenuse at a particular point. The distance between that point and the adjacent side is some fraction that is the product of 1 the distance from the vertex, and 2 the magnitude of the opposite side. The second input variable in this type of multiplier positions a slotted plate perpendicular to the adjacent side. That slot contains a block, and that block's position in its slot is determined by another block right next to it. The latter slides along the hypotenuse, so the two blocks are positioned at a distance from the (trig.) adjacent side by an amount proportional to the product. To provide the product as an output, a third element, another slotted plate, also moves parallel to the (trig.) opposite side of the theoretical triangle. As usual, the slot is perpendicular to the direction of movement. A block in its slot, pivoted to the hypotenuse block positions it. A special type of integrator, used at a point where only moderate accuracy was needed, was based on a steel ball, instead of a disc. It had two inputs, one to rotate the ball, and the other to define the angle of the ball's rotating axis. That axis was always in a plane that contained the axes of two movement pick-off rollers, quite similar to the mechanism of a rolling-ball computer mouse (in that mechanism, the pick-off rollers were roughly the same diameter as the ball). The pick-off roller axes were at right angles. A pair of rollers "above" and "below" the pick-off plane were mounted in rotating holders that were geared together. That gearing was driven by the angle input, and established the rotating axis of the ball. The other input rotated the "bottom" roller to make the ball rotate. Essentially, the whole mechanism, called a component integrator, was a variable-speed drive with one motion input and two outputs, as well as an angle input. The angle input varied the ratio (and direction) of coupling between the "motion" input and the outputs according to the sine and cosine of the input angle. Although they did not accomplish any computation, electromechanical position servos were essential in mechanical analog computers of the "rotating-shaft" type for providing operating torque to the inputs of subsequent computing mechanisms, as well as driving output data-transmission devices such as large torque-transmitter synchros in naval computers. Other readout mechanisms, not directly part of the computation, included internal odometer-like counters with interpolating drum dials for indicating internal variables, and mechanical multi-turn limit stops. Considering that accurately controlled rotational speed in analog fire-control computers was a basic element of their accuracy, there was a motor with its average speed controlled by a balance wheel, hairspring, jeweled-bearing differential, a twin-lobe cam, and spring-loaded contacts (ship's AC power frequency was not necessarily accurate, nor dependable enough, when these computers were designed). Electronic analog computers Electronic analog computers typically have front panels with numerous jacks (single-contact sockets) that permit patch cords (flexible wires with plugs at both ends) to create the interconnections that define the problem setup. In addition, there are precision high-resolution potentiometers (variable resistors) for setting up (and, when needed, varying) scale factors. In addition, there is usually a zero-center analog pointer-type meter for modest-accuracy voltage measurement. Stable, accurate voltage sources provide known magnitudes. Typical electronic analog computers contain anywhere from a few to a hundred or more operational amplifiers ("op amps"), named because they perform mathematical operations. Op amps are a particular type of feedback amplifier with very high gain and stable input (low and stable offset). They are always used with precision feedback components that, in operation, all but cancel out the currents arriving from input components. The majority of op amps in a representative setup are summing amplifiers, which add and subtract analog voltages, providing the result at their output jacks. As well, op amps with capacitor feedback are usually included in a setup; they integrate the sum of their inputs with respect to time. Integrating with respect to another variable is the nearly exclusive province of mechanical analog integrators; it is almost never done in electronic analog computers. However, given that a problem solution does not change with time, time can serve as one of the variables. Other computing elements include analog multipliers, nonlinear function generators, and analog comparators. Electrical elements such as inductors and capacitors used in electrical analog computers had to be carefully manufactured to reduce non-ideal effects. For example, in the construction of AC power network analyzers, one motive for using higher frequencies for the calculator (instead of the actual power frequency) was that higher-quality inductors could be more easily made. Many general-purpose analog computers avoided the use of inductors entirely, re-casting the problem in a form that could be solved using only resistive and capacitive elements, since high-quality capacitors are relatively easy to make. The use of electrical properties in analog computers means that calculations are normally performed in real time (or faster), at a speed determined mostly by the frequency response of the operational amplifiers and other computing elements. In the history of electronic analog computers, there were some special high-speed types. Nonlinear functions and calculations can be constructed to a limited precision (three or four digits) by designing function generators—special circuits of various combinations of resistors and diodes to provide the nonlinearity. Typically, as the input voltage increases, progressively more diodes conduct. When compensated for temperature, the forward voltage drop of a transistor's base-emitter junction can provide a usably accurate logarithmic or exponential function. Op amps scale the output voltage so that it is usable with the rest of the computer. Any physical process that models some computation can be interpreted as an analog computer. Some examples, invented for the purpose of illustrating the concept of analog computation, include using a bundle of spaghetti as a model of sorting numbers; a board, a set of nails, and a rubber band as a model of finding the convex hull of a set of points; and strings tied together as a model of finding the shortest path in a network. These are all described in Dewdney (1984). Components Analog computers often have a complicated framework, but they have, at their core, a set of key components that perform the calculations. The operator manipulates these through the computer's framework. Key hydraulic components might include pipes, valves and containers. Key mechanical components might include rotating shafts for carrying data within the computer, miter gear differentials, disc/ball/roller integrators, cams (2-D and 3-D), mechanical resolvers and multipliers, and torque servos. Key electrical/electronic components might include: precision resistors and capacitors operational amplifiers multipliers potentiometers fixed-function generators The core mathematical operations used in an electric analog computer are: addition integration with respect to time inversion multiplication exponentiation logarithm division In some analog computer designs, multiplication is much preferred to division. Division is carried out with a multiplier in the feedback path of an Operational Amplifier. Differentiation with respect to time is not frequently used, and in practice is avoided by redefining the problem when possible. It corresponds in the frequency domain to a high-pass filter, which means that high-frequency noise is amplified; differentiation also risks instability. Limitations In general, analog computers are limited by non-ideal effects. An analog signal is composed of four basic components: DC and AC magnitudes, frequency, and phase. The real limits of range on these characteristics limit analog computers. Some of these limits include the operational amplifier offset, finite gain, and frequency response, noise floor, non-linearities, temperature coefficient, and parasitic effects within semiconductor devices. For commercially available electronic components, ranges of these aspects of input and output signals are always figures of merit. Decline In the 1950s to 1970s, digital computers based on first vacuum tubes, transistors, integrated circuits and then micro-processors became more economical and precise. This led digital computers to largely replace analog computers. Even so, some research in analog computation is still being done. A few universities still use analog computers to teach control system theory. The American company Comdyna manufactured small analog computers. At Indiana University Bloomington, Jonathan Mills has developed the Extended Analog Computer based on sampling voltages in a foam sheet. At the Harvard Robotics Laboratory, analog computation is a research topic. Lyric Semiconductor's error correction circuits use analog probabilistic signals. Slide rules are still popular among aircraft personnel. Resurgence With the development of very-large-scale integration (VLSI) technology, Yannis Tsividis' group at Columbia University has been revisiting analog/hybrid computers design in standard CMOS process. Two VLSI chips have been developed, an 80th-order analog computer (250 nm) by Glenn Cowan in 2005 and a 4th-order hybrid computer (65 nm) developed by Ning Guo in 2015, both targeting at energy-efficient ODE/PDE applications. Glenn's chip contains 16 macros, in which there are 25 analog computing blocks, namely integrators, multipliers, fanouts, few nonlinear blocks. Ning's chip contains one macro block, in which there are 26 computing blocks including integrators, multipliers, fanouts, ADCs, SRAMs and DACs. Arbitrary nonlinear function generation is made possible by the ADC+SRAM+DAC chain, where the SRAM block stores the nonlinear function data. The experiments from the related publications revealed that VLSI analog/hybrid computers demonstrated about 1–2 orders magnitude of advantage in both solution time and energy while achieving accuracy within 5%, which points to the promise of using analog/hybrid computing techniques in the area of energy-efficient approximate computing. In 2016, a team of researchers developed a compiler to solve differential equations using analog circuits. Analog computers are also used in neuromorphic computing, and in 2021 a group of researchers have shown that a specific type of artificial neural network called a spiking neural network was able to work with analog neuromorphic computers. Practical examples These are examples of analog computers that have been constructed or practically used: Boeing B-29 Superfortress Central Fire Control System Deltar E6B flight computer Kerrison Predictor Leonardo Torres y Quevedo's Analogue Calculating Machines based on "fusee sans fin" Librascope, aircraft weight and balance computer Mechanical computer Mechanical integrators, for example, the planimeter Nomogram Norden bombsight Rangekeeper, and related fire control computers Scanimate Torpedo Data Computer Torquetum Water integrator MONIAC, economic modelling Ishiguro Storm Surge Computer Analog (audio) synthesizers can also be viewed as a form of analog computer, and their technology was originally based in part on electronic analog computer technology. The ARP 2600's Ring Modulator was actually a moderate-accuracy analog multiplier. The Simulation Council (or Simulations Council) was an association of analog computer users in US. It is now known as The Society for Modeling and Simulation International. The Simulation Council newsletters from 1952 to 1963 are available online and show the concerns and technologies at the time, and the common use of analog computers for missilry.

A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol , is a unit of angular measurement equal to of one degree. Since one degree is of a turn, or complete rotation, one arcminute is of a turn. The nautical mile (nmi) was originally defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth circumference is very near . A minute of arc is of a radian. A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol , is of an arcminute, of a degree, of a turn, and (about ) of a radian. These units originated in Babylonian astronomy as sexagesimal (base 60) subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying, and marksmanship. To express even smaller angles, standard SI prefixes can be employed; the milliarcsecond (mas) and microarcsecond (μas), for instance, are commonly used in astronomy. For a three-dimensional area such as on a sphere, square arcminutes or seconds may be used. Symbols and abbreviations The prime symbol () designates the arcminute, though a single quote (U+0027) is commonly used where only ASCII characters are permitted. One arcminute is thus written as 1′. It is also abbreviated as arcmin or amin. Similarly, double prime (U+2033) designates the arcsecond, though a double quote (U+0022) is commonly used where only ASCII characters are permitted. One arcsecond is thus written as 1″. It is also abbreviated as arcsec or asec. In celestial navigation, seconds of arc are rarely used in calculations, the preference usually being for degrees, minutes, and decimals of a minute, for example, written as 42° 25.32′ or 42° 25.322′. This notation has been carried over into marine GPS receivers, which normally display latitude and longitude in the latter format by default. Common examples The average apparent diameter of the full Moon is about 31 arcminutes, or 0.52°. One arcminute is the approximate resolution of the human eye. One arcsecond is the approximate angle subtended by a U.S. dime coin (18 mm) at a distance of . An arcsecond is also the angle subtended by an object of diameter at a distance of one astronomical unit, an object of diameter at one light-year, an object of diameter one astronomical unit () at a distance of one parsec, per the definition of the latter. One milliarcsecond is about the size of a half dollar, seen from a distance equal to that between the Washington Monument and the Eiffel Tower. One microarcsecond is about the size of a period at the end of a sentence in the Apollo mission manuals left on the Moon as seen from Earth. One nanoarcsecond is about the size of a penny on Neptune's moon Triton as observed from Earth. Also notable examples of size in arcseconds are: Hubble Space Telescope has calculational resolution of 0.05 arcseconds and actual resolution of almost 0.1 arcseconds, which is close to the diffraction limit. At crescent phase, Venus measures between 60.2 and 66 seconds of arc. History The concepts of degrees, minutes, and seconds—as they relate to the measure of both angles and time—derive from Babylonian astronomy and time-keeping. Influenced by the Sumerians, the ancient Babylonians divided the Sun's perceived motion across the sky over the course of one full day into 360 degrees. Each degree was subdivided into 60 minutes and each minute into 60 seconds. Thus, one Babylonian degree was equal to four minutes in modern terminology, one Babylonian minute to four modern seconds, and one Babylonian second to (approximately 0.067) of a modern second. Uses Astronomy Since antiquity, the arcminute and arcsecond have been used in astronomy: in the ecliptic coordinate system as latitude (β) and longitude (λ); in the horizon system as altitude (Alt) and azimuth (Az); and in the equatorial coordinate system as declination (δ). All are measured in degrees, arcminutes, and arcseconds. The principal exception is right ascension (RA) in equatorial coordinates, which is measured in time units of hours, minutes, and seconds. Contrary to what one might assume, minutes and seconds of arc do not directly relate to minutes and seconds of time, in either the rotational frame of the Earth around its own axis (day), or the Earth's rotational frame around the Sun (year). The Earth's rotational rate around its own axis is 15 minutes of arc per minute of time (360 degrees / 24 hours in day); the Earth's rotational rate around the Sun (not entirely constant) is roughly 24 minutes of time per minute of arc (from 24 hours in day), which tracks the annual progression of the Zodiac. Both of these factor in what astronomical objects you can see from surface telescopes (time of year) and when you can best see them (time of day), but neither are in unit correspondence. For simplicity, the explanations given assume a degree/day in the Earth's annual rotation around the Sun, which is off by roughly 1%. The same ratios hold for seconds, due to the consistent factor of 60 on both sides. The arcsecond is also often used to describe small astronomical angles such as the angular diameters of planets (e.g. the angular diameter of Venus which varies between 10″ and 60″); the proper motion of stars; the separation of components of binary star systems; and parallax, the small change of position of a star or Solar System body as the Earth revolves about the Sun. These small angles may also be written in milliarcseconds (mas), or thousandths of an arcsecond. The unit of distance called the parsec, abbreviated from the parallax angle of one arc second, was developed for such parallax measurements. The distance from the Sun to a celestial object is the reciprocal of the angle, measured in arcseconds, of the object's apparent movement caused by parallax. The European Space Agency's astrometric satellite Gaia, launched in 2013, can approximate star positions to 7 microarcseconds (µas). Apart from the Sun, the star with the largest angular diameter from Earth is R Doradus, a red giant with a diameter of 0.05″. Because of the effects of atmospheric blurring, ground-based telescopes will smear the image of a star to an angular diameter of about 0.5″; in poor conditions this increases to 1.5″ or even more. The dwarf planet Pluto has proven difficult to resolve because its angular diameter is about 0.1″. Space telescopes are not affected by the Earth's atmosphere but are diffraction limited. For example, the Hubble Space Telescope can reach an angular size of stars down to about 0.1″. Techniques exist for improving seeing on the ground. Adaptive optics, for example, can produce images around 0.05″ on a 10 m class telescope. Cartography Minutes (′) and seconds (″) of arc are also used in cartography and navigation. At sea level one minute of arc along the equator equals exactly one geographical mile (not to be confused with international mile or statute mile) along the Earth's equator or approximately . A second of arc, one sixtieth of this amount, is roughly . The exact distance varies along meridian arcs or any other great circle arcs because the figure of the Earth is slightly oblate (bulges a third of a percent at the equator). Positions are traditionally given using degrees, minutes, and seconds of arcs for latitude, the arc north or south of the equator, and for longitude, the arc east or west of the Prime Meridian. Any position on or above the Earth's reference ellipsoid can be precisely given with this method. However, when it is inconvenient to use base-60 for minutes and seconds, positions are frequently expressed as decimal fractional degrees to an equal amount of precision. Degrees given to three decimal places ( of a degree) have about the precision of degrees-minutes-seconds ( of a degree) and specify locations within about . For navigational purposes positions are given in degrees and decimal minutes, for instance The Needles lighthouse is at 50º 39.734’N 001º 35.500’W. Property cadastral surveying Related to cartography, property boundary surveying using the metes and bounds system and cadastral surveying relies on fractions of a degree to describe property lines' angles in reference to cardinal directions. A boundary "mete" is described with a beginning reference point, the cardinal direction North or South followed by an angle less than 90 degrees and a second cardinal direction, and a linear distance. The boundary runs the specified linear distance from the beginning point, the direction of the distance being determined by rotating the first cardinal direction the specified angle toward the second cardinal direction. For example, North 65° 39′ 18″ West 85.69 feet would describe a line running from the starting point 85.69 feet in a direction 65° 39′ 18″ (or 65.655°) away from north toward the west. Firearms The arcminute is commonly found in the firearms industry and literature, particularly concerning the precision of rifles, though the industry refers to it as minute of angle (MOA). It is especially popular as a unit of measurement with shooters familiar with the imperial measurement system because 1 MOA subtends a circle with a diameter of 1.047 inches (which is often rounded to just 1 inch) at 100 yards ( at or 2.908 cm at 100 m), a traditional distance on American target ranges. The subtension is linear with the distance, for example, at 500 yards, 1 MOA subtends 5.235 inches, and at 1000 yards 1 MOA subtends 10.47 inches. Since many modern telescopic sights are adjustable in half (), quarter () or eighth () MOA increments, also known as clicks, zeroing and adjustments are made by counting 2, 4 and 8 clicks per MOA respectively. For example, if the point of impact is 3 inches high and 1.5 inches left of the point of aim at 100 yards (which for instance could be measured by using a spotting scope with a calibrated reticle), the scope needs to be adjusted 3 MOA down, and 1.5 MOA right. Such adjustments are trivial when the scope's adjustment dials have a MOA scale printed on them, and even figuring the right number of clicks is relatively easy on scopes that click in fractions of MOA. This makes zeroing and adjustments much easier: To adjust a MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 × 2 = 6 clicks down and 1.5 x 2 = 3 clicks right To adjust a MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 x 4 = 12 clicks down and 1.5 × 4 = 6 clicks right To adjust a MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 x 8 = 24 clicks down and 1.5 × 8 = 12 clicks right Another common system of measurement in firearm scopes is the milliradian (mrad). Zeroing an mrad based scope is easy for users familiar with base ten systems. The most common adjustment value in mrad based scopes is  mrad (which approximates MOA). To adjust a  mrad scope 0.9 mrad down and 0.4 mrad right, the scope needs to be adjusted 9 clicks down and 4 clicks right (which equals approximately 3 and 1.5 MOA respectively). One thing to be aware of is that some MOA scopes, including some higher-end models, are calibrated such that an adjustment of 1 MOA on the scope knobs corresponds to exactly 1 inch of impact adjustment on a target at 100 yards, rather than the mathematically correct 1.047 inches. This is commonly known as the Shooter's MOA (SMOA) or Inches Per Hundred Yards (IPHY). While the difference between one true MOA and one SMOA is less than half of an inch even at 1000 yards, this error compounds significantly on longer range shots that may require adjustment upwards of 20–30 MOA to compensate for the bullet drop. If a shot requires an adjustment of 20 MOA or more, the difference between true MOA and SMOA will add up to 1 inch or more. In competitive target shooting, this might mean the difference between a hit and a miss. The physical group size equivalent to m minutes of arc can be calculated as follows: group size = tan() × distance. In the example previously given, for 1 minute of arc, and substituting 3,600 inches for 100 yards, 3,600 tan() ≈ 1.047 inches. In metric units 1 MOA at 100 metres ≈ 2.908 centimetres. Sometimes, a precision-oriented firearm's performance will be measured in MOA. This simply means that under ideal conditions (i.e. no wind, high-grade ammo, clean barrel, and a stable mounting platform such as a vise or a benchrest used to eliminate shooter error), the gun is capable of producing a group of shots whose center points (center-to-center) fit into a circle, the average diameter of circles in several groups can be subtended by that amount of arc. For example, a 1 MOA rifle should be capable, under ideal conditions, of repeatably shooting 1-inch groups at 100 yards. Most higher-end rifles are warrantied by their manufacturer to shoot under a given MOA threshold (typically 1 MOA or better) with specific ammunition and no error on the shooter's part. For example, Remington's M24 Sniper Weapon System is required to shoot 0.8 MOA or better, or be rejected from sale by quality control. Rifle manufacturers and gun magazines often refer to this capability as sub-MOA, meaning a gun consistently shooting groups under 1 MOA. This means that a single group of 3 to 5 shots at 100 yards, or the average of several groups, will measure less than 1 MOA between the two furthest shots in the group, i.e. all shots fall within 1 MOA. If larger samples are taken (i.e., more shots per group) then group size typically increases, however this will ultimately average out. If a rifle was truly a 1 MOA rifle, it would be just as likely that two consecutive shots land exactly on top of each other as that they land 1 MOA apart. For 5-shot groups, based on 95% confidence, a rifle that normally shoots 1 MOA can be expected to shoot groups between 0.58 MOA and 1.47 MOA, although the majority of these groups will be under 1 MOA. What this means in practice is if a rifle that shoots 1-inch groups on average at 100 yards shoots a group measuring 0.7 inches followed by a group that is 1.3 inches, this is not statistically abnormal. The metric system counterpart of the MOA is the milliradian (mrad or 'mil'), being equal to of the target range, laid out on a circle that has the observer as centre and the target range as radius. The number of milliradians on a full such circle therefore always is equal to 2 × × 1000, regardless the target range. Therefore, 1 MOA ≈ 0.2909 mrad. This means that an object which spans 1 mrad on the reticle is at a range that is in metres equal to the object's size in millimetres (e.g. an object of 100 mm subtending 1 mrad is 100 metres away). So there is no conversion factor required, contrary to the MOA system. A reticle with markings (hashes or dots) spaced with a one mrad apart (or a fraction of a mrad) are collectively called a mrad reticle. If the markings are round they are called mil-dots. In the table below conversions from mrad to metric values are exact (e.g. 0.1 mrad equals exactly 10 mm at 100 metres), while conversions of minutes of arc to both metric and imperial values are approximate. 1′ at 100 yards is about 1.047 inches 1′ ≈ 0.291 mrad (or 29.1 mm at 100 m, approximately 30 mm at 100 m) 1 mrad ≈ 3.44′, so  mrad ≈ ′ 0.1 mrad equals exactly 1 cm at 100 m, or exactly 0.36 inches at 100 yards Human vision In humans, 20/20 vision is the ability to resolve a spatial pattern separated by a visual angle of one minute of arc, from a distance of twenty feet. A 20/20 letter subtends 5 minutes of arc total. Materials The deviation from parallelism between two surfaces, for instance in optical engineering, is usually measured in arcminutes or arcseconds. In addition, arcseconds are sometimes used in rocking curve (ω-scan) x ray diffraction measurements of high-quality epitaxial thin films. Manufacturing Some measurement devices make use of arcminutes and arcseconds to measure angles when the object being measured is too small for direct visual inspection. For instance, a toolmaker's optical comparator will often include an option to measure in "minutes and seconds".

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Acceleration is one of several components of kinematics, the study of motion. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object. The magnitude of an object's acceleration, as described by Newton's Second Law, is the combined effect of two causes: the net balance of all external forces acting onto that object — magnitude is directly proportional to this net resulting force; that object's mass, depending on the materials out of which it is made — magnitude is inversely proportional to the object's mass. The SI unit for acceleration is metre per second squared (, ). For example, when a vehicle starts from a standstill (zero velocity, in an inertial frame of reference) and travels in a straight line at increasing speeds, it is accelerating in the direction of travel. If the vehicle turns, an acceleration occurs toward the new direction and changes its motion vector. The acceleration of the vehicle in its current direction of motion is called a linear (or tangential during circular motions) acceleration, the reaction to which the passengers on board experience as a force pushing them back into their seats. When changing direction, the effecting acceleration is called radial (or centripetal during circular motions) acceleration, the reaction to which the passengers experience as a centrifugal force. If the speed of the vehicle decreases, this is an acceleration in the opposite direction of the velocity vector (mathematically a negative, if the movement is unidimensional and the velocity is positive), sometimes called deceleration or retardation, and passengers experience the reaction to deceleration as an inertial force pushing them forward. Such negative accelerations are often achieved by retrorocket burning in spacecraft. Both acceleration and deceleration are treated the same, as they are both changes in velocity. Each of these accelerations (tangential, radial, deceleration) is felt by passengers until their relative (differential) velocity are neutralized in reference to the acceleration due to change in speed. Definition and properties Average acceleration An object's average acceleration over a period of time is its change in velocity, , divided by the duration of the period, . Mathematically, Instantaneous acceleration Instantaneous acceleration, meanwhile, is the limit of the average acceleration over an infinitesimal interval of time. In the terms of calculus, instantaneous acceleration is the derivative of the velocity vector with respect to time: As acceleration is defined as the derivative of velocity, , with respect to time and velocity is defined as the derivative of position, , with respect to time, acceleration can be thought of as the second derivative of with respect to : (Here and elsewhere, if motion is in a straight line, vector quantities can be substituted by scalars in the equations.) By the fundamental theorem of calculus, it can be seen that the integral of the acceleration function is the velocity function ; that is, the area under the curve of an acceleration vs. time ( vs. ) graph corresponds to the change of velocity. Likewise, the integral of the jerk function , the derivative of the acceleration function, can be used to find the change of acceleration at a certain time: Units Acceleration has the dimensions of velocity (L/T) divided by time, i.e. L T−2. The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second. Other forms An object moving in a circular motion—such as a satellite orbiting the Earth—is accelerating due to the change of direction of motion, although its speed may be constant. In this case it is said to be undergoing centripetal (directed towards the center) acceleration. Proper acceleration, the acceleration of a body relative to a free-fall condition, is measured by an instrument called an accelerometer. In classical mechanics, for a body with constant mass, the (vector) acceleration of the body's center of mass is proportional to the net force vector (i.e. sum of all forces) acting on it (Newton's second law): where is the net force acting on the body, is the mass of the body, and is the center-of-mass acceleration. As speeds approach the speed of light, relativistic effects become increasingly large. Tangential and centripetal acceleration The velocity of a particle moving on a curved path as a function of time can be written as: with equal to the speed of travel along the path, and a unit vector tangent to the path pointing in the direction of motion at the chosen moment in time. Taking into account both the changing speed and the changing direction of , the acceleration of a particle moving on a curved path can be written using the chain rule of differentiation for the product of two functions of time as: where is the unit (inward) normal vector to the particle's trajectory (also called the principal normal), and is its instantaneous radius of curvature based upon the osculating circle at time . The components are called the tangential acceleration and the normal or radial acceleration (or centripetal acceleration in circular motion, see also circular motion and centripetal force), respectively. Geometrical analysis of three-dimensional space curves, which explains tangent, (principal) normal and binormal, is described by the Frenet–Serret formulas. Special cases Uniform acceleration Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period. A frequently cited example of uniform acceleration is that of an object in free fall in a uniform gravitational field. The acceleration of a falling body in the absence of resistances to motion is dependent only on the gravitational field strength (also called acceleration due to gravity). By Newton's Second Law the force acting on a body is given by: Because of the simple analytic properties of the case of constant acceleration, there are simple formulas relating the displacement, initial and time-dependent velocities, and acceleration to the time elapsed: where is the elapsed time, is the initial displacement from the origin, is the displacement from the origin at time , is the initial velocity, is the velocity at time , and is the uniform rate of acceleration. In particular, the motion can be resolved into two orthogonal parts, one of constant velocity and the other according to the above equations. As Galileo showed, the net result is parabolic motion, which describes, e.g., the trajectory of a projectile in vacuum near the surface of Earth. Circular motion In uniform circular motion, that is moving with constant speed along a circular path, a particle experiences an acceleration resulting from the change of the direction of the velocity vector, while its magnitude remains constant. The derivative of the location of a point on a curve with respect to time, i.e. its velocity, turns out to be always exactly tangential to the curve, respectively orthogonal to the radius in this point. Since in uniform motion the velocity in the tangential direction does not change, the acceleration must be in radial direction, pointing to the center of the circle. This acceleration constantly changes the direction of the velocity to be tangent in the neighboring point, thereby rotating the velocity vector along the circle. For a given speed , the magnitude of this geometrically caused acceleration (centripetal acceleration) is inversely proportional to the radius of the circle, and increases as the square of this speed: For a given angular velocity , the centripetal acceleration is directly proportional to radius . This is due to the dependence of velocity on the radius . Expressing centripetal acceleration vector in polar components, where is a vector from the centre of the circle to the particle with magnitude equal to this distance, and considering the orientation of the acceleration towards the center, yields As usual in rotations, the speed of a particle may be expressed as an angular speed with respect to a point at the distance as Thus This acceleration and the mass of the particle determine the necessary centripetal force, directed toward the centre of the circle, as the net force acting on this particle to keep it in this uniform circular motion. The so-called 'centrifugal force', appearing to act outward on the body, is a so-called pseudo force experienced in the frame of reference of the body in circular motion, due to the body's linear momentum, a vector tangent to the circle of motion. In a nonuniform circular motion, i.e., the speed along the curved path is changing, the acceleration has a non-zero component tangential to the curve, and is not confined to the principal normal, which directs to the center of the osculating circle, that determines the radius for the centripetal acceleration. The tangential component is given by the angular acceleration , i.e., the rate of change of the angular speed times the radius . That is, The sign of the tangential component of the acceleration is determined by the sign of the angular acceleration (), and the tangent is always directed at right angles to the radius vector. Relation to relativity Special relativity The special theory of relativity describes the behavior of objects traveling relative to other objects at speeds approaching that of light in vacuum. Newtonian mechanics is exactly revealed to be an approximation to reality, valid to great accuracy at lower speeds. As the relevant speeds increase toward the speed of light, acceleration no longer follows classical equations. As speeds approach that of light, the acceleration produced by a given force decreases, becoming infinitesimally small as light speed is approached; an object with mass can approach this speed asymptotically, but never reach it. General relativity Unless the state of motion of an object is known, it is impossible to distinguish whether an observed force is due to gravity or to acceleration—gravity and inertial acceleration have identical effects. Albert Einstein called this the equivalence principle, and said that only observers who feel no force at all—including the force of gravity—are justified in concluding that they are not accelerating.

The conservation and restoration of cultural property focuses on protection and care of cultural property (tangible cultural heritage), including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars. Definition Conservation of cultural property involves protection and restoration using "any methods that prove effective in keeping that property in as close to its original condition as possible for as long as possible." Conservation of cultural heritage is often associated with art collections and museums and involves collection care and management through tracking, examination, documentation, exhibition, storage, preventive conservation, and restoration. The scope has widened from art conservation, involving protection and care of artwork and architecture, to conservation of cultural heritage, also including protection and care of a broad set of other cultural and historical works. Conservation of cultural heritage can be described as a type of ethical stewardship. It may broadly be divided into: Conservation and restoration of movable cultural property Conservation and restoration of immovable cultural property Conservation of cultural property applies simple ethical guidelines: Minimal intervention; Appropriate materials and reversible methods; Full documentation of all work undertaken. Often there are compromises between preserving appearance, maintaining original design and material properties, and ability to reverse changes. Reversibility is now emphasized so as to reduce problems with future treatment, investigation, and use. In order for conservators to decide upon an appropriate conservation strategy and apply their professional expertise accordingly, they must take into account views of the stakeholder, the values, artist's intent, meaning of the work, and the physical needs of the material. Cesare Brandi in his Theory of Restoration, describes restoration as "the methodological moment in which the work of art is appreciated in its material form and in its historical and aesthetic duality, with a view to transmitting it to the future". History and science Key dates Some consider the tradition of conservation of cultural heritage in Europe to have begun in 1565 with the restoration of the Sistine Chapel frescoes, but more ancient examples include the work of Cassiodorus. Brief history The care of cultural heritage has a long history, one that was primarily aimed at fixing and mending objects for their continued use and aesthetic enjoyment. Until the early 20th century, artists were normally the ones called upon to repair damaged artworks. During the 19th century, however, the fields of science and art became increasingly intertwined as scientists such as Michael Faraday began to study the damaging effects of the environment to works of art. Louis Pasteur carried out scientific analysis on paint as well. However, perhaps the first organized attempt to apply a theoretical framework to the conservation of cultural heritage came with the founding in the United Kingdom of the Society for the Protection of Ancient Buildings in 1877. The society was founded by William Morris and Philip Webb, both of whom were deeply influenced by the writings of John Ruskin. During the same period, a French movement with similar aims was being developed under the direction of Eugène Viollet-le-Duc, an architect and theorist, famous for his restorations of medieval buildings. Conservation of cultural heritage as a distinct field of study initially developed in Germany, where in 1888 Friedrich Rathgen became the first chemist to be employed by a Museum, the Koniglichen Museen, Berlin (Royal Museums of Berlin). He not only developed a scientific approach to the care of objects in the collections, but disseminated this approach by publishing a Handbook of Conservation in 1898. The early development of conservation of cultural heritage in any area of the world is usually linked to the creation of positions for chemists within museums. In British archaeology, key research and technical experimentation in conservation was undertaken by women such as Ione Gedye both in the field and in archaeological collections, particularly those of the Institute of Archaeology, London. In the United Kingdom, pioneering research into painting materials and conservation, ceramics, and stone conservation was conducted by Arthur Pillans Laurie, academic chemist and Principal of Heriot-Watt University from 1900. Laurie's interests were fostered by William Holman Hunt. In 1924 the chemist Harold Plenderleith began to work at the British Museum with Alexander Scott in the recently created Research Laboratory, although he was actually employed by the Department of Scientific and Industrial Research in the early years. Plenderleith's appointment may be said to have given birth to the conservation profession in the UK, although there had been craftsmen in many museums and in the commercial art world for generations. This department was created by the museum to address the deteriorating condition of objects in the collection, damages which were a result of their being stored in the London Underground tunnels during the First World War. The creation of this department moved the focus for the development of conservation theory and practice from Germany to Britain, and made the latter a prime force in this fledgling field. In 1956 Plenderleith wrote a significant handbook called The Conservation of Antiquities and Works of Art, which supplanted Rathgen's earlier tome and set new standards for the development of art and conservation science. In the United States, the development of conservation of cultural heritage can be traced to the Fogg Art Museum, and Edward Waldo Forbes, its director from 1909 to 1944. He encouraged technical investigation, and was Chairman of the Advisory Committee for the first technical journal, Technical Studies in the Field of the Fine Arts, published by the Fogg from 1932 to 1942. Importantly he also brought onto the museum staff chemists. Rutherford John Gettens was the first of such in the US to be permanently employed by an art museum. He worked with George L. Stout, the founder and first editor of Technical Studies. Gettens and Stout co-authored Painting Materials: A Short Encyclopaedia in 1942, reprinted in 1966. This compendium is still cited regularly. Only a few dates and descriptions in Gettens' and Stout's book are now outdated. George T. Oliver, of Oliver Brothers Art Restoration and Art Conservation-Boston (Est. 1850 in New York City) invented the vacuum hot table for relining paintings in 1920s; he filed a patent for the table in 1937. Taylor's prototype table, which he designed and constructed, is still in operation. Oliver Brothers is believed to be the first and the oldest continuously operating art restoration company in the United States. The focus of conservation development then accelerated in Britain and America, and it was in Britain that the first International Conservation Organisations developed. The International Institute for Conservation of Historic and Artistic Works (IIC) was incorporated under British law in 1950 as "a permanent organization to co-ordinate and improve the knowledge, methods, and working standards needed to protect and preserve precious materials of all kinds." The rapid growth of conservation professional organizations, publications, journals, newsletters, both internationally and in localities, has spearheaded the development of the conservation profession, both practically and theoretically. Art historians and theorists such as Cesare Brandi have also played a significant role in developing conservation science theory. In recent years ethical concerns have been at the forefront of developments in conservation. Most significantly has been the idea of preventive conservation. This concept is based in part on the pioneering work by Garry Thomson CBE, and his book Museum Environment, first published in 1978. Thomson was associated with the National Gallery in London; it was here that he established a set of guidelines or environmental controls for the best conditions in which objects could be stored and displayed within the museum environment. Although his exact guidelines are no longer rigidly followed, they did inspire this field of conservation. Conservation laboratories Conservators routinely use chemical and scientific analysis for the examination and treatment of cultural works. The modern conservation laboratory uses equipment such as microscopes, spectrometers, and various x-ray regime instruments to better understand objects and their components. The data thus collected helps in deciding the conservation treatments to be provided to the object. Ethics The conservator's work is guided by ethical standards. These take the form of applied ethics. Ethical standards have been established across the world, and national and international ethical guidelines have been written. One such example is: American Institute for Conservation Code of Ethics and Guidelines for Practice Conservation OnLine provides resources on ethical issues in conservation, including examples of codes of ethics and guidelines for professional conduct in conservation and allied fields; and charters and treaties pertaining to ethical issues involving the preservation of cultural property. As well as standards of practice conservators deal with wider ethical concerns, such as the debates as to whether all art is worth preserving. Keeping up with the international contemporary scenario, recent concerns with sustainability in conservation have emerged. The common understanding that "the care of an artifact should not come at the undue expense of the environment" is generally well accepted within the community and is already contemplated in guidelines of diverse institutions related to the field. Practice Preventive conservation Many cultural works are sensitive to environmental conditions such as temperature, humidity and exposure to visible light and ultraviolet radiation. These works must be protected in controlled environments where such variables are maintained within a range of damage-limiting levels. For example, watercolour paintings usually require shielding from sunlight to prevent fading of pigments. Collections care is an important element of museum policy. It is an essential responsibility of members of the museum profession to create and maintain a protective environment for the collections in their care, whether in store, on display, or in transit. A museum should carefully monitor the condition of collections to determine when an artifact requires conservation work and the services of a qualified conservator. Interventive conservation and restoration A teaching programme of interventive conservation was established in the UK at the Institute of Archaeology by Ione Gedye, which is still teaching interventive conservators today. A principal aim of a cultural conservator is to reduce the rate of deterioration of an object. Both non-interventive and interventive methodologies may be employed in pursuit of this goal. Interventive conservation refers to any direct interaction between the conservator and the material fabric of the object. Interventive actions are carried out for a variety of reasons, including aesthetic choices, stabilization needs for structural integrity, or cultural requirements for intangible continuity. Examples of interventive treatments include the removal of discolored varnish from a painting, the application of wax to a sculpture, and the washing and rebinding of a book. Ethical standards within the field require that the conservator fully justify interventive actions and carry out documentation before, during, and after the treatment. One of the guiding principles of conservation of cultural heritage has traditionally been the idea of reversibility, that all interventions with the object should be fully reversible and that the object should be able to be returned to the state in which it was prior to the conservator's intervention. Although this concept remains a guiding principle of the profession, it has been widely critiqued within the conservation profession and is now considered by many to be "a fuzzy concept." Another important principle of conservation is that all alterations should be well documented and should be clearly distinguishable from the original object. An example of a highly publicized interventive conservation effort would be the conservation work conducted on the Sistine Chapel. Example of an archaeological discovery and restoration of a mural painting Example of the restoration of an oil painting Sustainable conservation Recognising that conservation practices should not harm the environment, harm people, or contribute to global warming, the conservation-restoration profession has more recently focused on practices that reduce waste, reduce energy costs, and minimise the use of toxic or harmful solvents. A number of research projects, working groups, and other initiatives have explored how conservation can become a more environmentally sustainable profession. Sustainable conservation practices apply both to work within cultural institutions (e.g. museums, art galleries, archives, libraries, research centres and historic sites) as well as to businesses and private studios. Choice of materials Conservators and restorers use a wide variety of materials - in conservation treatments, and those used to safely transport, display and store cultural heritage items. These materials can include solvents, papers and boards, fabrics, adhesives and consolidants, plastics and foams, wood products, and many others. Stability and longevity are two important factors conservators consider when selecting materials; sustainability is becoming an increasingly important third. Examples of sustainable material choices and practices include: Using biodegradable products or those with less environmental impact where possible; Using 'green solvents' instead of more toxic alternatives, or treatment strategies that use much smaller amounts of solvents - for example, semi-rigid aqueous gels, emulsions or nano materials; Preparing smaller amounts of material (e.g. adhesives) to avoid waste; Observing recommended disposal protocols for chemicals, recyclable materials and compostable materials, particularly to avoid contamination of waterways; Choosing protective work wear that can be washed or cleaned and reused, rather than disposable options; Tracking stock quantities to avoid over-buying, especially for materials with expiration dates; Using durable materials for packing that may be washed and re-used, such as Tyvek or Mylar; Repurposing consumables such as blotting paper, non-woven fabrics, and polyester film when they are no longer fit for their original purpose; Using locally produced products whenever possible, to reduce carbon footprints; Reusing packaging materials such as cardboard boxes, plastic wrap and wooden crates; Using standard sizes of packaging and package designs that reduce waste; These decisions are not always straightforward - for example, installing deionised or distilled water filters in laboratories reduces waste associated with purchasing bottled products, but increases energy consumption. Similarly, locally-made papers and boards may reduce inherent carbon miles but they may be made with pulp sourced from old growth forests. Another dilemma is that many conservation-grade materials are chosen because they do not biodegrade. For example, when selecting a plastic with which to make storage enclosures, conservators prefer to use relatively long-lived plastics because they have better ageing properties - they are less likely to become yellow, leach plasticisers, or lose structural integrity and crumble (examples include polyethylene, polypropylene, and polyester). These plastics will also take longer to degrade in landfill. Energy use Many conservators and cultural organisations have sought to reduce the energy costs associated with controlling indoor storage and display environments (temperature, relative humidity, air filtration, and lighting levels) as well as those associated with the transport of cultural heritage items for exhibitions and loans. In general, lowering the temperature reduces the rate at which damaging chemical reactions occur within materials. For example, storing cellulose acetate film at 10 °C instead of 21 °C is estimated to increase its usable life by over 100 years. Controlling the relative humidity of air helps to reduce hydrolysis reactions and minimises cracking, distortion and other physical changes in hygroscopic materials. Changes in temperature will also bring about changes in relative humidity. Therefore, the conservation profession has placed great importance on controlling indoor environments. Temperature and humidity can be controlled through passive means (e.g. insulation, building design) or active means (air conditioning). Active controls typically require much higher energy use. Energy use increases with specificity - e.g. in will require more energy to maintain a quantity of air to a narrow temperature range (20-22 °C) than to a broad range (18-25 °C). In the past, conservation recommendations have often called for very tight, inflexible temperature and relative humidity set points. In other cases, conservators have recommended strict environmental conditions for buildings that could not reasonably be expected to achieve them, due to the quality of build, local environmental conditions (e.g. recommending temperate conditions for a building located in the tropics) or the financial circumstances of the organisation. This has been an area of particular debate for cultural heritage organisations who lend and borrow cultural items to each other - often, the lender will specify strict environmental conditions as part of the loan agreement, which may be very expensive for the borrowing organisation to achieve, or impossible. The energy costs associated with cold storage and digital storage are also gaining more attention. Cold storage is a very effective strategy to preserve at-risk collections such as cellulose nitrate and cellulose acetate film, which can deteriorate beyond use within decades at ambient conditions. Digital storage costs are rising for both born-digital cultural heritage (photographs, audiovisual, time-based media) and to store digital preservation and access copies of cultural heritage. Digital storage capacity is a major factor in the complexity of preserving digital heritage such as video games, social media, messaging services, and email. Other areas where energy use can be reduced within conservation and restoration include: Exhibition lighting - e.g. using lower-energy LED lighting systems and light sensors that switch lights on only when visitors are present; Installation of green energy capture systems in cultural organisations, such as solar photovoltaic plates, wind energy systems, and heat pumps; Improving the energy performance of cultural buildings by installing insulation, sealing gaps, reducing the number of windows and installing double-glazing: Using microclimates to house small groups of climate-sensitive objects instead of seeking to control the environmental conditions of the whole building. Country by country look United States Heritage Preservation, in partnership with the Institute of Museum and Library Services, a U.S. federal agency, produced The Heritage Health Index. The results of this work was the report A Public Trust at Risk: The Heritage Health Index Report on the State of America's Collections, which was published in December 2005 and concluded that immediate action is needed to prevent the loss of 190 million artifacts that are in need of conservation treatment. The report made four recommendations: Institutions must give priority to providing safe conditions for the collections they hold in trust. Every collecting institution must develop an emergency plan to protect its collections and train staff to carry it out. Every institution must assign responsibility for caring for collections to members of its staff. Individuals at all levels of government and in the private sector must assume responsibility for providing the support that will allow these collections to survive. United Kingdom In October 2006, the Department for Culture, Media and Sport, a governmental department, authored a document: "Understanding the Future: Priorities for England's Museums". This document was based on several years of consultation aimed to lay out the government's priorities for museums in the 21st century. The document listed the following as priorities for the next decade: Museums will fulfil their potential as learning resources (pp 7–10). Museums will be embedded into the delivery of education in every school in the country. Understanding of the effectiveness of museum education will be improved further and best practice built into education programmes. The value of museums' collections as a research resource will be well understood and better links built between the academic community and museums. Museums will embrace their role in fostering, exploring, celebrating and questioning the identities of diverse communities (pp 11–14). The sector needs to work with partners in academia and beyond to create an intellectual framework supporting museums' capacity to tackle issues of identity. The museum sector must continue to develop improved practical techniques for engaging communities of all sorts. Museums' collections will be more dynamic and better used (pp 15–18). Government and the sector will find new ways to encourage museums to collect actively and strategically, especially the record of contemporary society. The sector will develop new collaborative approaches to sharing and developing collections and related expertise. Museums' workforce will be dynamic, highly skilled and representative (pp 17–22). Museums' governing bodies and workforce will be representative of the communities they serve. Find more varied ways for a broader range of skills to come into museums. Improve continuing professional development. Museums will work more closely with each other and partners outside the sector (pp 23–26). A consistent evidence base of the contribution of all kinds of museums to the full range of public service agendas will be developed. There will be deeper and longer lasting partnerships between the national museums and a broader range of regional partners. Museums' international roles will be strengthened to improve museum programmes in this country and Britain's image, reputation and relationships abroad. The conservation profession response to this report was on the whole less than favourable, the Institute of Conservation (ICON) published their response under the title "A Failure of Vision". It had the following to say: Concluding: Further to this the ICON website summary report lists the following specific recommendations: A national survey to find out what the public want from museums, what motivates them to visit them and what makes for a rewarding visit. A review of survey results and prioritisation of the various intrinsic, instrumental and institutional values to provide a clear basis for a 10-year strategy HR consultants to be brought in from the commercial sector to review recruitment, career development and working practices in the national and regional museums. A commitment to examine the potential for using Museum Accreditation as a more effective driver for improving recruitment, diversity, and career development across the sector. DCMS to take full account of the eventual findings of the current Commons Select Committee enquiry into Care of Collections in the final version of this document The adoption of those recommendations of the recent House of Lords inquiry into Science and Heritage which might affect the future of museums. In November 2008, the UK-based think tank Demos published an influential pamphlet entitled It's a material world: caring for the public realm, in which they argue for integrating the public directly into efforts to conserve material culture, particularly that which is in the public, their argument, as stated on page 16, demonstrates their belief that society can benefit from conservation as a paradigm as well as a profession: Training Training in conservation of cultural heritage for many years took the form of an apprenticeship, whereby an apprentice slowly developed the necessary skills to undertake their job. For some specializations within conservation this is still the case. However, it is more common in the field of conservation today that the training required to become a practicing conservator comes from a recognized university course in conservation of cultural heritage. The university can rarely provide all the necessary training in first hand experience that an apprenticeship can, and therefore in addition to graduate level training the profession also tends towards encouraging conservation students to spend time as an intern. Conservation of cultural heritage is an interdisciplinary field as conservators have backgrounds in the fine arts, sciences (including chemistry, biology, and materials science), and closely related disciplines, such as art history, archaeology, and anthropology. They also have design, fabrication, artistic, and other special skills necessary for the practical application of that knowledge. Within the various schools that teach conservation of cultural heritage, the approach differs according to the educational and vocational system within the country, and the focus of the school itself. This is acknowledged by the American Institute for Conservation who advise "Specific admission requirements differ and potential candidates are encouraged to contact the programs directly for details on prerequisites, application procedures, and program curriculum". In France, training for heritage conservation is taught by four schools : , L'École supérieure des Beaux-Arts Tours, Angers, Le Mans, L'Université Paris 1 Panthéon-Sorbonne, Institut national du patrimoine. Associations and professional organizations Societies devoted to the care of cultural heritage have been in existence around the world for many years. One early example is the founding in 1877 of the Society for the Protection of Ancient Buildings in Britain to protect the built heritage, this society continues to be active today. The 14th Dalai Lama and the Tibetan people work to preserve their cultural heritage with organizations including the Tibetan Institute of Performing Arts and an international network of eight Tibet Houses. The built heritage was at the forefront of the growth of member based organizations in the United States. Preservation Virginia, founded in Richmond in 1889 as the Association for the Preservation of Virginia Antiquities, was the United States' first statewide historic preservation group. Today, professional conservators join and take part in the activities of numerous conservation associations and professional organizations with the wider field, and within their area of specialization. In Europe, E.C.C.O. European Confederation of Conservator-Restorers Organisations was established in 1991 by 14 European Conservator-Restorers' Organisations. Currently representing close to 6.000 professionals within 23 countries and 26 members organisations, including one international body (IADA), E.C.C.O. embodies the field of preservation of cultural heritage, both movable and immovable. These organizations exist to "support the conservation professionals who preserve our cultural heritage". This involves upholding professional standards, promoting research and publications, providing educational opportunities, and fostering the exchange of knowledge among cultural conservators, allied professionals, and the public.

Action Against Hunger () is a global humanitarian organization which originated in France and is committed to ending world hunger. The organization helps malnourished children and provides communities with access to safe water and sustainable solutions to hunger. Pakistan's situation has significant ramifications for food security, particularly with the ongoing high levels of inflation. The added impact of climate change intensifies security concerns, leaving an increasing number of individuals without viable means to provide food and shelter for themselves and their families. In 2022, Action Against Hunger worked in 56 countries around the world with more than 8,990 employees helping 28 million people in need. Action Against Hunger was established in 1979 by a group of French doctors, scientists, and writers. Nobel Prize-winning physicist Alfred Kastler served as the organization's first chairman. Currently, Mumbai-based businessman and philanthropist Ashwini Kakkar serves as International President of Action Against Hunger network. The group initially provided assistance to Afghan refugees in Pakistan, famine-stricken Ugandan communities, and Cambodian refugees in Thailand. It expanded to address additional humanitarian concerns in Africa, the Middle East, Southeast Asia, the Balkans, and elsewhere during the 1980s and 1990s. Action Against Hunger's Scientific Committee pioneered the therapeutic milk formula (F100), now used by all major humanitarian aid organizations to treat acute malnutrition. Early results showed that treatment with F100 has the capacity to reduce the mortality rate of severely malnourished children to below 5%, with a median hospital fatality rate quoted of 23.5% A few years later, the therapeutic milk was repackaged as ready-to-use therapeutic foods (RUTFs), a peanut-based paste packaged like a power bar. These bars allow for the treatment of malnutrition at home and do not require any preparation or refrigeration. The international network currently has headquarters in eight countries – France, Germany, Spain, the United States, Canada, Italy, India, and the UK. Its four main areas of work include nutrition, food security, water and sanitation, and advocacy. The integrated approaches with various sectors of intervention are: Nutrition and Health Water, Sanitation and Hygiene Food Security & Livelihoods Emergency Response In 2022, Action Against Hunger USA is leading a USAID-funded project to address health and nutrition challenges associated with policy, advocacy, financing, and governance in communities around the world, and will work in partnership with leading organizations such as Pathfinder International, Amref Health Africa, Global Communities, Humanity & Inclusion, Kupenda for the Children, and Results for Development. Restaurants against hunger Action Against Hunger partners with leaders from the food and beverage industry to bring attention to global hunger. Each year, several campaigns are run by the network to raise funds and support the organisation's programs : Restaurants Against Hunger and Love Food Give Food. Countries of intervention In 2022, Action Against Hunger International Network is present in 56 countries: Africa Burkina Faso, Burundi, Cameroon, Ivory Coast, Ethiopia, Kenya, Liberia, Malawi, Madagascar, Mali, Mauritania, Niger, Nigeria, Uganda, Central African Republic, Democratic Republic of the Congo, Senegal, Sierra Leone, Somalia, South Sudan, Sudan, Tanzania, Chad, Zimbabwe, Zambia Asia Bangladesh, Myanmar, Cambodia, India, Indonesia, Nepal, Pakistan, Philippines, South Caucasus Caribbean Haïti Europe Turkey, Ukraine, Moldova, Romania, Poland Middle East Afghanistan, Lebanon, Syria, Palestinian Occupied Territories, Yemen, Jordan, Iraq Latin America Colombia, Guatemala, Nicaragua, Paraguay, Peru, Honduras Action Against Hunger international network Since 1995 Action Against Hunger developed an international network to have a bigger global impact. The Network has headquarters around the world: France, Germany, Spain, the United Kingdom, the United States, Canada, India, and Italy. Action Against Hunger has also a West Africa Regional Office (WARO) located in Dakar, a Horn and Eastern Africa Regional Office in Nairobi, and five logistic platforms (Lyon, Paris, Barcelona, Dubai, Panama). This network increases the human and financial capacities and enables specialisation per headquarter. Action Against Hunger in France, Spain and the USA are the operational headquarters. They manage the interventions directly on the field. In order to maximize efficiency and coherence, these three operational headquarters work under the principle of one headquarter per country of intervention. Action Against Hunger UK focuses on research, monitoring and evaluation, notably with Hunger Watch. The UK headquarters also plays an intermediary role with DFID. Action Against Hunger Canada raises public and private funds in North America and plays an increasing role on the national level. Action Against Hunger / Azione contro la Fame Italia raises private funds and promotes important campaigns in order to sensitize the Italian public opinion on hunger and malnutrition.

Aarau (, ) is a town, a municipality, and the capital of the northern Swiss canton of Aargau. The town is also the capital of the district of Aarau. It is German-speaking and predominantly Protestant. Aarau is situated on the Swiss plateau, in the valley of the Aare, on the river's right bank, and at the southern foot of the Jura Mountains, and is west of Zürich, south of Basel and northeast of Bern. The municipality borders directly on the canton of Solothurn to the west. It is the largest town in Aargau. At the beginning of 2010 Rohr became a district of Aarau. The official language of Aarau is (the Swiss variety of Standard) German, but the main spoken language is the local variant of the Alemannic Swiss German dialect. Geography and geology The old city of Aarau is situated on a rocky outcrop at a narrowing of the Aare river valley, at the southern foot of the Jura mountains. Newer districts of the city lie to the south and east of the outcrop, as well as higher up the mountain, and in the valley on both sides of the Aare. The neighboring municipalities are Küttigen to the north and Buchs to the east, Suhr to the south-east, Unterentfelden to the south, and Eppenberg-Wöschnau and Erlinsbach to the west. Aarau and the nearby neighboring municipalities have grown together and now form an interconnected agglomeration. The only exception is Unterentfelden whose settlements are divided from Aarau by the extensive forests of Gönhard and Zelgli. Approximately nine-tenths of the city is south of the Aare, and one tenth is to the north. It has an area, , of . Of this area, 6.3% is used for agricultural purposes, while 34% is forested. Of the rest of the land, 55.2% is settled (buildings or roads) and the remainder (4.5%) is non-productive (rivers or lakes). The lowest elevation, , is found at the banks of the Aar, and the highest elevation, at , is the Hungerberg on the border with Küttigen. Climate History Prehistory A few artifacts from the Neolithic period were found in Aarau. Near the location of the present train station, the ruins of a settlement from the Bronze Age (about 1000 BC) have been excavated. The Roman road between Salodurum (Solothurn) and Vindonissa passed through the area, along the route now covered by the Bahnhofstrasse. In 1976 divers in the Aare found part of a seven-meter wide wooden bridge from the late Roman times. Middle Ages Aarau was founded around AD 1472 by the counts of Kyburg. Aarau is first mentioned in 1248 as Arowe. Around 1250 it was mentioned as Arowa. However the first mention of a city sized settlement was in 1256. The town was ruled from the "Rore" tower, which has been incorporated into the modern city hall. In 1273 the counts of Kyburg died out. Agnes of Kyburg, who had no male relations, sold the family's lands to King Rudolf I von Habsburg. He granted Aarau its city rights in 1283. In the 14th century the city was expanded in two stages, and a second defensive wall was constructed. A deep ditch separated the city from its "suburb;" its location is today marked by a wide street named "Graben" (meaning Ditch). In 1415 Bern invaded lower Aargau with the help of Solothurn. Aarau capitulated after a short resistance, and was forced to swear allegiance to the new rulers. In the 16th century, the rights of the lower classes were abolished. In March 1528 the citizens of Aarau allowed the introduction of Protestantism at the urging of the Bernese. A growth in population during the 16th Century led to taller buildings and denser construction methods. Early forms of industry developed at this time; however, unlike in other cities, no guilds were formed in Aarau. On 11 August 1712, the Peace of Aarau was signed into effect. This granted each canton the right to choose their own religion thereby ending Catholicism's control. Starting in the early 18th century, the textile industry was established in Aarau. German immigration contributed to the city's favorable conditions, in that they introduced the cotton and silk factories. These highly educated immigrants were also responsible for educational reform and the enlightened, revolutionary spirit that developed in Aarau. 1798: Capital of the Helvetic Republic On 27 December 1797, the last Tagsatzung of the Old Swiss Confederacy was held in Aarau. Two weeks later a French envoy continued to foment the revolutionary opinions of the city. The contrast between a high level of education and a low level of political rights was particularly great in Aarau, and the city refused to send troops to defend the Bernese border. By Mid-March 1798 Aarau was occupied by French troops. On 22 March 1798 Aarau was declared the capital of the Helvetic Republic. It is therefore the first capital of a unified Switzerland. Parliament met in the city hall. On 20 September, the capital was moved to Lucerne. Aarau as canton capital In 1803, Napoleon ordered the fusion of the cantons of Aargau, Baden and Fricktal. Aarau was declared the capital of the new, enlarged canton of Aargau. In 1820 the city wall was torn down, with the exception of the individual towers and gates, and the defensive ditches were filled in. The wooden bridge, dating from the Middle Ages, across the Aare was destroyed by floods three times in thirty years, and was replaced with a steel suspension bridge in 1851. This was replaced by a concrete bridge in 1952. The city was linked up to the Swiss Central Railway in 1856. The textile industry in Aarau broke down in about 1850 because of the protectionist tariff policies of neighboring states. Other industries had developed by that time to replace it, including the production of mathematical instruments, shoes and cement. Beginning in 1900, numerous electrical enterprises developed. By the 1960s, more citizens worked in service industries or for the canton-level government than in manufacturing. During the 1980s many of the industries left Aarau completely. In 1802 the Canton School was established; it was the first non-parochial high school in Switzerland. It developed a good reputation, and was home to Nobel Prize winners Albert Einstein, Paul Karrer, and Werner Arber, as well as several Swiss politicians and authors. The purchase of a manuscript collection in 1803 laid the foundation for what would become the Cantonal Library, which contains a Bible annotated by Huldrych Zwingli, along with the manuscripts and incunabula. More newspapers developed in the city, maintaining the revolutionary atmosphere of Aarau. Beginning in 1820, Aarau has been a refuge for political refugees. The urban educational and cultural opportunities of Aarau were extended through numerous new institutions. A Theatre and Concert Hall was constructed in 1883, which was renovated and expanded in 1995–96. The Aargau Nature Museum opened in 1922. A former cloth warehouse was converted into a small theatre in 1974, and the alternative culture center KIFF (Culture in the fodder factory) was established in a former animal fodder factory. Origin of the name The earliest use of the place name was in 1248 (in the form Arowe), and probably referred to the settlement in the area before the founding of the city. It comes, along with the name of the River Aare (which was called Arula, Arola, and Araris in early times), from the German word Au, meaning floodplain. Old town The historic old town forms an irregular square, consisting of four parts (called Stöcke). To the south lies the Laurenzenvorstadt, that is, the part of the town formerly outside the city wall. One characteristic of the city is its painted gables, for which Aarau is sometimes called the "City of beautiful Gables". The old town, Laurenzenvorstadt, government building, cantonal library, state archive and art museum are all listed as heritage sites of national significance. The buildings in the old city originate, on the whole, from building projects during the 16th century, when nearly all the Middle Age period buildings were replaced or expanded. The architectural development of the city ended in the 18th century, when the city began to expand beyond its (still existing) wall. Most of the buildings in the "suburb" date from this time. The "Schlössli" (small Castle), Rore Tower and the upper gate tower have remained nearly unchanged since the 13th century. The "Schlössli" is the oldest building in the city. It was already founded at the time of the establishment of the city shortly after 1200; the exact date is not known. City hall was built around Rore Tower in 1515. The upper gate tower stands beside the southern gate in the city wall, along the road to Lucerne and Bern. The jail has been housed in it since the Middle Ages. A Carillon was installed in the tower in the middle of the 20th century, the bells for which were provided by the centuries-old bell manufacturers of Aarau. The town church was built between 1471 and 1478. During the Reformation, in 1528, its twelve altars and accompanying pictures were destroyed. The "Justice fountain" (Gerechtigkeitsbrunnen) was built in 1634, and is made of French limestone; it includes a statue of Lady Justice made of sandstone, hence the name. It was originally in the street in front of city hall, but was moved to its present location in front of the town church in 1905 due to increased traffic. Economy , Aarau had an unemployment rate of 2.35%. , there were 48 people employed in the primary economic sector and about 9 businesses involved in this sector. 4,181 people are employed in the secondary sector and there are 164 businesses in this sector. 20,186 people are employed in the tertiary sector, with 1,461 businesses in this sector. This is a total of over 24,000 jobs, since Aarau's population is about 16,000 it draws workers from many surrounding communities. there were 8,050 total workers who lived in the municipality. Of these, 4,308 or about 53.5% of the residents worked outside Aarau while 17,419 people commuted into the municipality for work. There were a total of 21,161 jobs (of at least 6 hours per week) in the municipality. The largest employer in Aarau is the cantonal government, the offices of which are distributed across the entire city at numerous locations. One of the two head offices of the Aargauer Zeitung, Switzerland's fifth largest newspaper, is located in Aarau, as are the Tele M1 television channel studios, and several radio stations. Kern & Co., founded in 1819, was an internationally known geodetic instrument manufacturer based in Aarau. However, it was taken over by Wild Leitz in 1988, and was closed in 1991. The small scale of Aarau causes it to continually expand the borders of its growth. The urban center lies in the middle of the "Golden Triangle" between Zürich, Bern, and Basel, and Aarau is having increasing difficulty in maintaining the independence of its economic base from the neighboring large cities. The idea of merging Aarau with its neighboring suburbs has been recently discussed in the hope of arresting the slowly progressing losses. Manufacture include bells, mathematical instruments, electrical goods, cotton textiles, cutlery, chemicals, shoes, and other products. Aarau is famous for the quality of their instruments, cutlery and their bells. Markets and fairs Every Saturday morning there is a vegetable market in the Graben at the edge of the Old City. It is supplied with regional products. In the last week of September the MAG (Market of Aarauer Tradesmen) takes place there, with regional companies selling their products. The "Rüeblimärt" is held in the same place on the first Wednesday in November, which is a Carrot fair. The Aarau fair is held at the ice skating rink during the Spring. Transport Aarau railway station is a terminus of the S-Bahn Zürich on the line S11. The town is also served with public transport provided by Busbetrieb Aarau AG. Routes Population The population of Aarau grew continuously from 1800 until about 1960, when the city reached a peak population of 17,045, more than five times its population in 1800. However, since 1960 the population has fallen by 8%. There are three reasons for this population loss: firstly, since the completion of Telli (a large apartment complex), the city has not had any more considerable land developments. Secondly, the number of people per household has fallen; thus, the existing dwellings do not hold as many people. Thirdly, population growth was absorbed by neighboring municipalities in the regional urban area, and numerous citizens of Aarau moved into the countryside. This trend might have stopped since the turn of the 21st century. Existing industrial developments are being used for new purposes instead of standing empty. Aarau has a population (as of ) of . , 19.8% of the population was made up of foreign nationals. Over the last 10 years the population has grown at a rate of 1%.

Aargau ( , ), more formally the Canton of Aargau (; ; ; ), is one of the 26 cantons forming the Swiss Confederation. It is composed of eleven districts and its capital is Aarau. Aargau is one of the most northerly cantons of Switzerland. It is situated by the lower course of the Aare River, which is why the canton is called Aar-gau (meaning "Aare province"). It is one of the most densely populated regions of Switzerland. History Early history The area of Aargau and the surrounding areas were controlled by the Helvetians, a tribe of Celts, as far back as 200 BC. It was eventually occupied by the Romans and then by the 6th century, the Franks. The Romans built a major settlement called Vindonissa, near the present location of Brugg. Medieval Aargau The reconstructed Old High German name of Aargau is Argowe, first unambiguously attested (in the spelling Argue) in 795. The term described a territory only loosely equivalent to that of the modern canton, including the region between Aare and Reuss rivers, including Pilatus and Napf, i.e. including parts of the modern cantons of Bern (Bernese Aargau, Emmental, parts of the Bernese Oberland), Solothurn, Basel-Landschaft, Lucerne, Obwalden and Nidwalden, but not the parts of the modern canton east of the Reuss (Baden District), which were part of Zürichgau. Within the Frankish Empire (8th to 10th centuries), the area was a disputed border region between the duchies of Alamannia and Burgundy. A line of the von Wetterau (Conradines) intermittently held the countship of Aargau from 750 until about 1030, when they lost it (having in the meantime taken the name von Tegerfelden). This division became the ill-defined (and sparsely settled) outer border of the early Holy Roman Empire at its formation in the second half of the 10th century. Most of the region came under the control of the ducal house of Zähringen and the comital houses of Habsburg and Kyburg by about 1200. In the second half of the 13th century, the territory became divided between the territories claimed by the imperial cities of Bern, Lucerne and Solothurn and the Swiss canton of Unterwalden. The remaining portion, largely corresponding to the modern canton of Aargau, remained under the control of the Habsburgs until the "conquest of Aargau" by the Old Swiss Confederacy in 1415. Habsburg Castle itself, the original seat of the House of Habsburg, was taken by Bern in April 1415. The Habsburgs had founded a number of monasteries (with some structures enduring, e.g., in Wettingen and Muri), the closing of which by the government in 1841 was a contributing factor to the outbreak of the Swiss civil war – the "Sonderbund War" – in 1847. Under the Swiss Confederation When Frederick IV of Habsburg sided with Antipope John XXIII at the Council of Constance, Emperor Sigismund placed him under the Imperial ban. In July 1414, the Pope visited Bern and received assurances from them, that they would move against the Habsburgs. A few months later the Swiss Confederation denounced the Treaty of 1412. Shortly thereafter in 1415, Bern and the rest of the Swiss Confederation used the ban as a pretext to invade the Aargau. The Confederation was able to quickly conquer the towns of Aarau, Lenzburg, Brugg and Zofingen along with most of the Habsburg castles. Bern kept the southwest portion (Zofingen, Aarburg, Aarau, Lenzburg, and Brugg), northward to the confluence of the Aare and Reuss. The important city of Baden was taken by a united Swiss army and governed by all 8 members of the Confederation. Some districts, named the Freie Ämter (free bailiwicks) – Mellingen, Muri, Villmergen, and Bremgarten, with the countship of Baden – were governed as "subject lands" by all or some of the Confederates. Shortly after the conquest of the Aargau by the Swiss, Frederick humbled himself to the Pope. The Pope reconciled with him and ordered all of the taken lands to be returned. The Swiss refused and years later after no serious attempts at re-acquisition, the Duke officially relinquished rights to the Swiss. Unteraargau or Berner Aargau Bern's portion of the Aargau came to be known as the Unteraargau, though can also be called the Berner or Bernese Aargau. In 1514 Bern expanded north into the Jura and so came into possession of several strategically important mountain passes into the Austrian Fricktal. This land was added to the Unteraargau and was directly ruled from Bern. It was divided into seven rural bailiwicks and four administrative cities, Aarau, Zofingen, Lenzburg and Brugg. While the Habsburgs were driven out, many of their minor nobles were allowed to keep their lands and offices, though over time they lost power to the Bernese government. The bailiwick administration was based on a very small staff of officials, mostly made up of Bernese citizens, but with a few locals. When Bern converted during the Protestant Reformation in 1528, the Unteraargau also converted. At the beginning of the 16th century a number of anabaptists migrated into the upper Wynen and Rueder valleys from Zürich. Despite pressure from the Bernese authorities in the 16th and 17th centuries anabaptism never entirely disappeared from the Unteraargau. Bern used the Aargau bailiwicks mostly as a source of grain for the rest of the city-state. The administrative cities remained economically only of regional importance. However, in the 17th and 18th centuries Bern encouraged industrial development in Unteraargau and by the late 18th century it was the most industrialized region in the city-state. The high industrialization led to high population growth in the 18th century, for example between 1764 and 1798, the population grew by 35%, far more than in other parts of the canton. In 1870 the proportion of farmers in Aarau, Lenzburg, Kulm, and Zofingen districts was 34–40%, while in the other districts it was 46–57%. Freie Ämter The rest of the Freie Ämter were collectively administered as subject territories by the rest of the Confederation. Muri Amt was assigned to Zürich, Lucerne, Schwyz, Unterwalden, Zug and Glarus, while the Ämter of Meienberg, Richensee and Villmergen were first given to Lucerne alone. The final boundary was set in 1425 by an arbitration tribunal and Lucerne had to give the three Ämter to be collectively ruled. The four Ämter were then consolidated under a single Confederation bailiff into what was known in the 15th century as the Waggental Bailiwick (). In the 16th century, it came to be known as the Vogtei der Freien Ämter. While the Freien Ämter often had independent lower courts, they were forced to accept the Confederation's sovereignty. Finally, in 1532, the canton of Uri became part of the collective administration of the Freien Ämter. At the time of the Protestant Reformation, the majority of the Ämter converted to the new faith. In 1529, a wave of iconoclasm swept through the area and wiped away much of the old religion. After the defeat of Zürich in the second Battle of Kappel in 1531, the victorious five Catholic cantons marched their troops into the Freie Ämter and reconverted them to Catholicism. In the First War of Villmergen, in 1656, and the Toggenburg War (or Second War of Villmergen), in 1712, the Freie Ämter became the staging ground for the warring Reformed and Catholic armies. While the peace after the 1656 war did not change the status quo, the fourth Peace of Aarau in 1712 brought about a reorganization of power relations. The victory gave Zürich the opportunity to force the Catholic cantons out of the government in the county of Baden and the adjacent area of the Freie Ämter. The Freie Ämter were then divided in two by a line drawn from the gallows in Fahrwangen to the Oberlunkhofen church steeple. The northern part, the so-called Unteren Freie Ämter (lower Freie Ämter), which included the districts of Boswil (in part) and Hermetschwil and the Niederamt, were ruled by Zürich, Bern and Glarus. The southern part, the Oberen Freie Ämter (upper Freie Ämter), were ruled by the previous seven cantons but Bern was added to make an eighth. During the Helvetic Republic (1798–1803), the county of Baden, the Freie Ämter and the area known as the Kelleramt were combined into the canton of Baden. County of Baden The County of Baden was a shared condominium of the entire Old Swiss Confederacy. After the Confederacy conquest in 1415, they retained much of the Habsburg legal structure, which caused a number of problems. The local nobility had the right to hold the low court in only about one fifth of the territory. There were over 30 different nobles who had the right to hold courts scattered around the surrounding lands. All these overlapping jurisdictions caused numerous conflicts, but gradually the Confederation was able to acquire these rights in the county. The cities of Baden, Bremgarten and Mellingen became the administrative centers and held the high courts. Together with the courts, the three administrative centers had considerable local autonomy, but were ruled by a governor who was appointed by the Acht Orte every two years. After the Protestant victory at the Second Battle of Villmergen, the administration of the County changed slightly. Instead of the Acht Orte appointing a bailiff together, Zürich and Bern each appointed the governor for 7 out of 16 years while Glarus appointed him for the remaining two years. The chaotic legal structure and fragmented land ownership combined with a tradition of dividing the land among all the heirs in an inheritance prevented any large scale reforms. The governor tried in the 18th century to reform and standardize laws and ownership across the county, but with limited success. With an ever-changing administration, the County lacked a coherent long-term economic policy or support for reforms. By the end of the 18th century there were no factories or mills and only a few small cottage industries along the border with Zürich. Road construction first became a priority after 1750, when Zürich and Bern began appointing a governor for seven years. During the Protestant Reformation, some of the municipalities converted to the new faith. However, starting in 1531, some of the old parishes were converted back to the old faith. The governors were appointed from both Catholic and Protestant cantons and since they changed every two years, neither faith gained a majority in the county. After the French invasion, on 19 March 1798, the governments of Zürich and Bern agreed to the creation of the short lived canton of Baden in the Helvetic Republic. With the Act of Mediation in 1803, the canton of Baden was dissolved. Portions of the lands of the former County of Baden now became the District of Baden in the newly created canton of Aargau. After World War II, this formerly agrarian region saw striking growth and became the district with the largest and densest population in the canton (110,000 in 1990, 715 persons per km2). Forming the canton of Aargau The contemporary canton of Aargau was formed in 1803, a canton of the Swiss Confederation as a result of the Act of Mediation. It was a combination of three short-lived cantons of the Helvetic Republic: Aargau (1798–1803), Baden (1798–1803) and Fricktal (1802–1803). Its creation is therefore rooted in the Napoleonic era. In the year 2003, the canton of Aargau celebrated its 200th anniversary. French forces occupied the Aargau from 10 March to 18 April 1798; thereafter the Bernese portion became the canton of Aargau and the remainder formed the canton of Baden. Aborted plans to merge the two halves came in 1801 and 1802, and they were eventually united under the name Aargau, which was then admitted as a full member of the reconstituted Confederation following the Act of Mediation. Some parts of the canton of Baden at this point were transferred to other cantons: the Amt of Hitzkirch to Lucerne, whilst Hüttikon, Oetwil an der Limmat, Dietikon and Schlieren went to Zürich. In return, Lucerne's Amt of Merenschwand was transferred to Aargau (district of Muri). The Fricktal, ceded in 1802 by Austria via Napoleonic France to the Helvetic Republic, was briefly a separate canton of the Helvetic Republic (the canton of Fricktal) under a Statthalter ('Lieutenant'), but on 19 March 1803 (following the Act of Mediation) was incorporated into the canton of Aargau. The former cantons of Baden and Fricktal can still be identified with the contemporary districts – the canton of Baden is covered by the districts of Zurzach, Baden, Bremgarten, and Muri (albeit with the gains and losses of 1803 detailed above); the canton of Fricktal by the districts of Rheinfelden and Laufenburg (except for Hottwil which was transferred to that district in 2010). Chief magistracy The chief magistracy of Aargau changed its style repeatedly: first two consecutive Regierungsstatthalter : April 1798 – November 1801 Jakob Emmanuel Feer (1754–1833) 1802–1803 Johann Heinrich Rothpletz (1766–1833) Presidents of the Government Commission 10 March 1803 – 26 April 1803 Johann Rudolf Dolder (1753–1807) 26 April 1803 – 1815 a 'Small Council' (president rotating monthly) annual Amtsbürgermeister 1815–1831 annual Landammänner since 1815 Jewish history in Aargau In the 17th century, Aargau was the only federal condominium where Jews were tolerated. In 1774, they were restricted to just two towns, Endingen and Lengnau. While the rural upper class pressed incessantly for the expulsion the Jews, the financial interests of the authorities prevented it. They imposed special taxes on peddling and cattle trading, the primary Jewish professions. The Protestant occupiers also enjoyed the discomfort of the local Catholics by the presence of the Jewish community. The Jews were directly subordinate to the governor; from 1696, they were compelled to renew a letter of protection from him every 16 years. During this period, Jews and Christians were not allowed to live under the same roof, neither were Jews allowed to own land or houses. They were taxed at a much higher rate than others and, in 1712, the Lengnau community was "pillaged." In 1760, they were further restricted regarding marriages and procreation. An exorbitant tax was levied on marriage licenses; oftentimes, they were outright refused. This remained the case until the 19th century. In 1799, the Helvetic republic abolished all special tolls, and, in 1802, removed the poll tax. On 5 May 1809, they were declared citizens and given broad rights regarding trade and farming. They were still restricted to Endingen and Lengnau until 7 May 1846, when their right to move and reside freely within the canton of Aargau was granted. On 24 September 1856, the Swiss Federal Council granted them full political rights within Aargau, as well as broad business rights; however the majority Christian population did not fully abide by these new liberal laws. The time of 1860 saw the canton government voting to grant suffrage in all local rights and to give their communities autonomy. Before the law was enacted, it was however repealed due to vocal opposition led by the Ultramonte Party. Finally, the federal authorities in July 1863, granted all Jews full rights of citizens. However, they did not receive all of the rights in Endingen and Lengnau until a resolution of the Grand Council, on 15 May 1877, granted citizens' rights to the members of the Jewish communities of those places, giving them charters under the names of New Endingen and New Lengnau. The Swiss Jewish Kulturverein was instrumental in this fight from its founding in 1862 until it was dissolved 20 years later. During this period of diminished rights, they were not even allowed to bury their dead in Swiss soil and had to bury their dead on an island called Judenäule (Jews' Isle) on the Rhine near Waldshut. Beginning in 1603, the deceased Jews of the Surbtal communities were buried on the river island which was leased by the Jewish community. As the island was repeatedly flooded and devastated, in 1750 the Surbtal Jews asked the Tagsatzung to establish the Endingen cemetery in the vicinity of their communities. Geography The capital of the canton is Aarau, which is located on its western border, on the Aare. The canton borders Germany (Baden-Württemberg) to the north, the Rhine forming the border. To the west lie the Swiss cantons of Basel-Landschaft, Solothurn and Bern; the canton of Lucerne lies south, and Zürich and Zug to the east. Its total area is . Besides the Rhine, it contains two large rivers, the Aare and the Reuss. The canton of Aargau is one of the least mountainous Swiss cantons, forming part of a great table-land, to the north of the Alps and the east of the Jura, above which rise low hills. The surface of the country is diversified with undulating tracts and well-wooded hills, alternating with fertile valleys watered mainly by the Aare and its tributaries. The valleys alternate with hills, many of which are wooded. Slightly over one-third of the canton is wooded (), while nearly half is used from farming (). or about 2.4% of the canton is considered unproductive, mostly lakes (notably Lake Hallwil) and streams. With a population density of 450/km2 (1,200/sq mi), the canton has a relatively high amount of land used for human development, with or about 15% of the canton developed for housing or transportation. It contains the hot sulphur springs of Baden and Schinznach-Bad, while at Rheinfelden there are very extensive saline springs. Just below Brugg the Reuss and the Limmat join the Aar, while around Brugg are the ruined castle of Habsburg, the old convent of Königsfelden (with fine painted medieval glass) and the remains of the Roman settlement of Vindonissa (Windisch). Fahr Monastery forms a small exclave of the canton, otherwise surrounded by the canton of Zürich, and since 2008 is part of the Aargau municipality of Würenlos. Political subdivisions Districts Aargau is divided into 11 districts: Aarau with capital Aarau Baden with capital Baden Bremgarten with capital Bremgarten Brugg with capital Brugg Kulm with capital Unterkulm Laufenburg with capital Laufenburg Lenzburg with capital Lenzburg Muri with capital Muri Rheinfelden with capital Rheinfelden Zofingen with capital Zofingen Zurzach with capital Zurzach The most recent change in district boundaries occurred in 2010 when Hottwil transferred from Brugg to Laufenburg, following its merger with other municipalities, all of which were in Laufenburg. Municipalities There are (as of 2014) 213 municipalities in the canton of Aargau. As with most Swiss cantons there has been a trend since the early 2000s for municipalities to merge, though mergers in Aargau have so far been less radical than in other cantons. Coat of arms The blazon of the coat of arms is Per pale, dexter: sable, a fess wavy argent, charged with two cotises wavy azure; sinister: sky blue, three mullets of five argent. The flag and arms of the canton of Aargau date to 1803 and are an original design by Samuel Ringier-Seelmatter; the current official design, specifying the stars as five-pointed, dates to 1930.

The American Quarter Horse, or Quarter Horse, is an American breed of horse that excels at sprinting short distances. Its name is derived from its ability to outrun other horse breeds in races of a quarter mile or less; some have been clocked at speeds up to 44 mph (70.8 km/h). The development of the Quarter Horse traces to the 1600s. The American Quarter Horse is the most popular breed in the United States, and the American Quarter Horse Association is the largest breed registry in the world, with almost three million living American Quarter Horses registered in 2014. The American Quarter Horse is well known both as a race horse and for its performance in rodeos, horse shows, and as a working ranch horse. The compact body of the American Quarter Horse is well suited for the intricate and quick maneuvers required in reining, cutting, working cow horse, barrel racing, calf roping, and other western riding events, especially those involving live cattle. The American Quarter Horse is also used in English disciplines, driving, show jumping, dressage, hunting, and many other equestrian activities. The Texas Legislature designated the American Quarter Horse as the official "State Horse of Texas" in 2009, and Oklahoma also designated the Quarter Horse as its official state horse in 2022. Breed history Colonial era In the 1600s on the Eastern seaboard of colonial America, imported English Thoroughbred horses were first bred with assorted native horses. One of the most famous of these early imports was Janus, a Thoroughbred who was the grandson of the Godolphin Arabian. He was foaled in 1746, and imported to colonial Virginia in 1756. The influence of Thoroughbreds like Janus contributed genes crucial to the development of the colonial "Quarter Horse". The resulting horse was small, hardy, quick, and was used as a work horse during the week and a race horse on the weekends. As flat racing became popular with the colonists, the Quarter Horse gained even more popularity as a sprinter over courses that, by necessity, were shorter than the classic racecourses of England. These courses were often no more than a straight stretch of road or flat piece of open land. When competing against a Thoroughbred, local sprinters often won. As the Thoroughbred breed became established in America, many colonial Quarter Horses were included in the original American stud books. This began a long association between the Thoroughbred breed and what would later become officially known as the "Quarter Horse", named after the race distance at which it excelled. Some Quarter Horses have been clocked at up to 44 mph. Westward expansion In the 19th century, pioneers heading West needed a hardy, willing horse. On the Great Plains, settlers encountered horses that descended from the Spanish stock Hernán Cortés and other Conquistadors had introduced into the viceroyalty of New Spain, which became the Southwestern United States and Mexico. The horses of the West included herds of feral animals known as Mustangs, as well as horses domesticated by Native Americans, including the Comanche, Shoshoni and Nez Perce tribes. As the colonial Quarter Horse was crossed with these western horses, the pioneers found that the new crossbred had innate "cow sense", a natural instinct for working with cattle, making it popular with cattlemen on ranches. Development as a distinct breed Early foundation sires of Quarter horse type included Steel Dust, foaled 1843; Shiloh (or Old Shiloh), foaled 1844; Old Cold Deck (1862); Lock's Rondo, one of many "Rondo" horses, foaled in 1880; Old Billy—again, one of many "Billy" horses—foaled ; Traveler, a stallion of unknown breeding, known to have been in Texas by 1889; and Peter McCue, foaled 1895, registered as a Thoroughbred but of disputed pedigree. Another early foundation sire for the breed was Copperbottom, foaled in 1828, who tracks his lineage through the Byerley Turk, a foundation sire of the Thoroughbred horse breed. The main duty of the ranch horse in the American West was working cattle. Even after the invention of the automobile, horses were still irreplaceable for handling livestock on the range. Thus, major Texas cattle ranches, such as the King Ranch, the 6666 (Four Sixes) Ranch, and the Waggoner Ranch played a significant role in the development of the modern Quarter Horse. The skills required by cowboys and their horses became the foundation of the rodeo, a contest which began with informal competition between cowboys and expanded to become a major competitive event throughout the west. The Quarter Horse dominates in events that require speed as well as the ability to handle cattle. Sprint races were also popular weekend entertainment and racing became a source of economic gain for breeders. As a result, more Thoroughbred blood was added into the developing American Quarter Horse breed. The American Quarter Horse also benefitted from the addition of Arabian, Morgan, and even Standardbred bloodlines. In 1940, the American Quarter Horse Association (AQHA) was formed by a group of horsemen and ranchers from the Southwestern United States dedicated to preserving the pedigrees of their ranch horses. After winning the 1941 Fort Worth Exposition and Fat Stock Show grand champion stallion, the horse honored with the first registration number, P-1, was Wimpy, a descendant of the King Ranch foundation sire Old Sorrel. Other sires alive at the founding of the AQHA were given the earliest registration numbers Joe Reed P-3, Chief P-5, Oklahoma Star P-6, Cowboy P-12, and Waggoner's Rainy Day P-13. The Thoroughbred race horse Three Bars, alive in the early years of the AQHA, is recognized by the American Quarter Horse Hall of Fame as one of the significant foundation sires for the Quarter Horse breed. Other significant Thoroughbred sires seen in early AQHA pedigrees include Rocket Bar, Top Deck and Depth Charge. "Appendix" and "Foundation" horses Since the American Quarter Horse was formally established as a breed, the AQHA stud book has remained open to additional Thoroughbred blood via a performance standard. An "Appendix" American Quarter Horse is a first generation cross between a registered Thoroughbred and an American Quarter Horse or a cross between a "numbered" American Quarter Horse and an "appendix" American Quarter Horse. The resulting offspring is registered in the "appendix" of the American Quarter Horse Association's studbook, hence the nickname. Horses listed in the appendix may be entered in competition, but offspring are not initially eligible for full AQHA registration. If the Appendix horse meets certain conformational criteria and is shown or raced successfully in sanctioned AQHA events, the horse can earn its way from the appendix into the permanent studbook, making its offspring eligible for AQHA registration. Since Quarter Horse/Thoroughbred crosses continue to enter the official registry of the American Quarter Horse breed, this creates a continual gene flow from the Thoroughbred breed into the American Quarter Horse breed, which has altered many of the characteristics that typified the breed in the early years of its formation. Some breeders argue that the continued addition of Thoroughbred bloodlines are beginning to compromise the integrity of the breed standard. Some favor the earlier style of horse and have created several separate organizations to promote and register "Foundation" Quarter Horses. Modern American Quarter Horse The American Quarter Horse is a show horse, race horse, reining and cutting horse, rodeo competitor, ranch horse, and all-around family horse. Quarter Horses are commonly used in rodeo events such as barrel racing, calf roping and team roping; and gymkhana or O-Mok-See. Other stock horse events such as cutting and reining are open to all breeds but are dominated by American Quarter Horse. The breed is not only well-suited for western riding and cattle work. Many race tracks offer Quarter Horses a wide assortment of pari-mutuel horse racing with earnings in the millions. Quarter Horses have also been trained to compete in dressage and show jumping. They are also used for recreational trail riding and in mounted police units. The American Quarter Horse has also been exported worldwide. European nations such as Germany and Italy have imported large numbers of Quarter Horses. Next to the American Quarter Horse Association (which also encompasses Quarter Horses from Canada), the second largest registry of Quarter Horses is in Brazil, followed by Australia. In the UK the breed is also becoming very popular, especially with the two Western riding Associations, the Western Horse Association and The Western Equestrian Society. The British American Quarter Horse breed society is the AQHA-UK. With the internationalization of the discipline of reining and its acceptance as one of the official seven events of the World Equestrian Games, there is a growing international interest in Quarter Horses. The American Quarter Horse is the most popular breed in the United States, and the American Quarter Horse Association is the largest breed registry in the world, with nearly 3 million American Quarter Horses registered worldwide in 2014. Breed characteristics The Quarter Horse has a small, short, refined head with a straight profile, and a strong, well-muscled body, featuring a broad chest and powerful, rounded hindquarters. They usually stand between high, although some Halter-type and English hunter-type horses may grow as tall as . There are two main body types: the stock type and the hunter or racing type. The stock horse type is shorter, more compact, stocky and well-muscled, yet agile. The racing and hunter type Quarter Horses are somewhat taller and smoother muscled than the stock type, more closely resembling the Thoroughbred. Quarter Horses come in nearly all colors. The most common color is sorrel, a brownish red, part of the color group called chestnut by most other breed registries. Other recognized colors include bay, black, brown, buckskin, palomino, gray, dun, red dun, grullo (also occasionally referred to as blue dun), red roan, blue roan, bay roan, perlino, cremello, and white. In the past, spotted color patterns were excluded, but now with the advent of DNA testing to verify parentage, the registry accepts all colors as long as both parents are registered. Stock type A stock horse is a horse of a type that is well suited for working with livestock, particularly cattle. Reining and cutting horses are smaller in stature, with quick, agile movements and very powerful hindquarters. Western pleasure show horses are often slightly taller, with slower movements, smoother gaits, and a somewhat more level topline – though still featuring the powerful hindquarters characteristic of the Quarter Horse. Halter type Horses shown in-hand in Halter competition are larger yet, with a very heavily muscled appearance, while retaining small heads with wide jowls and refined muzzles. There is controversy amongst owners, breeder and veterinarians regarding the health effects of the extreme muscle mass that is currently fashionable in the specialized halter horse, which typically is and weighs in at over when fitted for halter competition. Not only are there concerns about the weight to frame ratio on the horse's skeletal system, but the massive build is also linked to hyperkalemic periodic paralysis (HYPP) in descendants of the stallion Impressive (see Genetic diseases below). Racing and hunter type Quarter Horse race horses are bred to sprint short distances ranging from 220 to 870 yards. Thus, they have long legs and are leaner than their stock type counterparts, but are still characterized by muscular hindquarters and powerful legs. Quarter Horses race primarily against other Quarter Horses, and their sprinting ability has earned them the nickname, "the world's fastest athlete." The show hunter type is slimmer, even more closely resembling a Thoroughbred, usually reflecting a higher percentage of appendix breeding. They are shown in hunter/jumper classes at both breed shows and in open USEF-rated horse show competition. Genetic diseases There are several genetic diseases of concern to Quarter Horse breeders: Hyperkalemic periodic paralysis (HYPP), which is caused by an autosomal dominant gene linked to the stallion Impressive. It is characterized by uncontrollable muscle twitching and substantial muscle weakness or paralysis among affected horses. Because it is a dominant gene, only one parent has to have the gene for it to be transmitted to offspring. There is a DNA test for HYPP, which is required by the AQHA. Since 2007, the AQHA bars registration of horses who possess the homozygous form (H/H) of the gene, and though heterozygous (H/N) horses are still eligible for registration, altering that status is currently being discussed. Additionally all Quarter Horses born 2007 or later that are confirmed to be descendants of Impressive must carry a note about the risks of HYPP on their registration papers. Due to HYPP, the halter classes are undergoing significant changes. Halter classes are dominated by the Impressive bloodline. Impressive, a very prolific halter horse, brought to the stock breeds the muscle mass that became popular in halter competition. This muscle mass is linked to HYPP, and as the condition is reduced within the breed, the style of horse in halter classes is also likely to change. Already there have been rule changes, including the creation of a "Performance Halter class" in which a horse must possess a Register of Merit in performance or racing before it can compete. Malignant hyperthermia. A causative mutated allele, ryanodine receptor 1 gene (RyR1) at nucleotide C7360G, generating a R2454G amino acid substitution. has been identified in the American Quarter Horse and breeds with Quarter Horse ancestry, inherited as an autosomal dominant It can be caused by overwork, anesthesia, or stress. Hereditary Equine Regional Dermal Asthenia (HERDA), also known as hyperelastosis cutis (HC). This is caused by an autosomal recessive gene, and thus, unlike HYPP, HERDA can only be transmitted if both parents carry the gene. When a horse has this disease, there is a collagen defect that results in the layers of skin not being held firmly together. Thus, when the horse is ridden under saddle or suffers trauma to the skin, the outer layer often splits or separates from the deeper layer, or it can tear off completely. It rarely heals without disfiguring scars. Sunburn can also be a concern. In dramatic cases, the skin can split along the back and even roll down the sides, with the horse literally being skinned alive. Most horses with HERDA are euthanized for humane reasons between the age of two and four years. The very hotly debated and controversial theory, put forth by researchers at Cornell University and Mississippi State University is that the sire line of the great foundation stallion Poco Bueno is implicated as the origin of the disease. As of May 9, 2007, Researchers working independently at Cornell University and at the University of California, Davis announced that a DNA test for HERDA has been developed. Over 1,500 horses were tested during the development phase of the test, which is now available to the general public through both institutions. Glycogen Branching Enzyme Deficiency (GBED) is a genetic disease where the horse is lacking an enzyme necessary for storing glycogen, the horse's heart muscle and skeletal muscles cannot function, leading to rapid death. The disease occurs in foals who are homozygous for the lethal GBED allele, meaning both parents carry one copy of the gene. The stallion King P-234 has been linked to this disease. There is a DNA blood test for this gene. Equine polysaccharide storage myopathy, also called EPSM or PSSM, is a metabolic muscular condition in horses that causes tying up, and is also related to a glycogen storage disorder. While also seen in some draft horse breeds, PSSM has been traced to three specific but undisclosed bloodlines in Quarter Horses, with an autosomal recessive inheritance pattern. 48% of Quarter Horses with symptoms of neuromuscular disease have PSSM. To some extent it can be diet controlled with specialized low-starch diets, but genetic testing is advised before breeding, as the condition exists at a subclinical level in approximately 6% of the general Quarter Horse population. Lethal White Syndrome. Although "cropout" Quarter Horses with Paint markings were not allowed to be registered for many years, the gene for such markings is a recessive and continued to periodically appear in Quarter Horse foals. Thus, it is believed that some Quarter Horses may carry the gene for Lethal White Syndrome. There is a DNA test for this condition. Cleft Palate Birth defect, this is not just a genetic disorder. There is not just one thing that will cause this issue. It can be caused from genetics, hormones, mineral deficiency, tranquilizers, or steroids. Cleft palates are extremely uncommon. The surgery to repair the cleft palate does not have a high success rate. Only about a 20% success rate is seen from the surgery. Quarter horses seem to have the most research done with them, and this defect occurs more in quarter horses based on the research. Some observations of a horse with a cleft palate and no surgery are: lifting head high when eating, dropping head low to drink, coughing when beginning of exercise, and placing wormers or other oral medications in the side of the jaw and taking about hour to administer full dose.

Anthroposophy is a spiritual movement which was founded in the early 20th century by the esotericist Rudolf Steiner that postulates the existence of an objective, intellectually comprehensible spiritual world, accessible to human experience. Followers of anthroposophy aim to engage in spiritual discovery through a mode of thought independent of sensory experience. While much of anthroposophy is pseudoscientific, proponents claim to present their ideas in a manner that is verifiable by rational discourse and say that they seek precision and clarity comparable to that obtained by scientists investigating the physical world. Anthroposophy has its roots in German idealism, mystical philosophies, and pseudoscience including racist pseudoscience. Critics and proponents alike acknowledge his many anti-racist statements, often far ahead of his contemporaries and predecessors still commonly cited today. Steiner chose the term anthroposophy (from Greek , 'human', and sophia, 'wisdom') to emphasize his philosophy's humanistic orientation. He defined it as "a scientific exploration of the spiritual world", Others have variously called it a "philosophy and cultural movement", a "spiritual movement", a "spiritual science", or "a system of thought". Anthroposophical ideas have been employed in alternative movements in many areas including education (both in Waldorf schools and in the Camphill movement), agriculture, medicine, banking, organizational development, and the arts. The main organization for advocacy of Steiner's ideas, the Anthroposophical Society, is headquartered at the Goetheanum in Dornach, Switzerland. Anthroposophy's supporters include writers Saul Bellow, and Selma Lagerlöf, painters Piet Mondrian, Wassily Kandinsky and Hilma af Klint, filmmaker Andrei Tarkovsky, child psychiatrist Eva Frommer, music therapist Maria Schüppel, Romuva religious founder Vydūnas, and former president of Georgia Zviad Gamsakhurdia. Though several prominent members of the Nazi Party were supporters of anthroposophy and its movements, including (an agriculturalist), SS colonel Hermann Schneider, and Gestapo chief Heinrich Müller, anti-Nazis such as Traute Lafrenz, a member of the White Rose resistance movement, were also followers. Rudolf Hess, the adjunct Führer, was a patron of Waldorf schools and a staunch defender of biodynamic agriculture. The historian of religion Olav Hammer has termed anthroposophy "the most important esoteric society in European history". Many scientists, physicians, and philosophers, including Michael Shermer, Michael Ruse, Edzard Ernst, David Gorski, and Simon Singh have criticized anthroposophy's application in the areas of medicine, biology, agriculture, and education to be dangerous and pseudoscientific. Some of Steiner's ideas that are unsupported or disproven by modern science, including: racial evolution, clairvoyance (Steiner claimed he was clairvoyant), and the Atlantis myth. History The early work of the founder of anthroposophy, Rudolf Steiner, culminated in his Philosophy of Freedom (also translated as The Philosophy of Spiritual Activity and Intuitive Thinking as a Spiritual Path). Here, Steiner developed a concept of free will based on inner experiences, especially those that occur in the creative activity of independent thought. By the beginning of the twentieth century, Steiner's interests turned almost exclusively to spirituality. His work began to draw the attention of others interested in spiritual ideas; among these was the Theosophical Society. From 1900 on, thanks to the positive reception his ideas received from Theosophists, Steiner focused increasingly on his work with the Theosophical Society, becoming the secretary of its section in Germany in 1902. During his leadership, membership increased dramatically, from just a few individuals to sixty-nine lodges. By 1907, a split between Steiner and the Theosophical Society became apparent. While the Society was oriented toward an Eastern and especially Indian approach, Steiner was trying to develop a path that embraced Christianity and natural science. The split became irrevocable when Annie Besant, then president of the Theosophical Society, presented the child Jiddu Krishnamurti as the reincarnated Christ. Steiner strongly objected and considered any comparison between Krishnamurti and Christ to be nonsense; many years later, Krishnamurti also repudiated the assertion. Steiner's continuing differences with Besant led him to separate from the Theosophical Society Adyar. He was subsequently followed by the great majority of the Theosophical Society's German members, as well as many members of other national sections. By this time, Steiner had reached considerable stature as a spiritual teacher and expert in the occult. He spoke about what he considered to be his direct experience of the Akashic Records (sometimes called the "Akasha Chronicle"), thought to be a spiritual chronicle of the history, pre-history, and future of the world and mankind. In a number of works, Steiner described a path of inner development he felt would let anyone attain comparable spiritual experiences. In Steiner's view, sound vision could be developed, in part, by practicing rigorous forms of ethical and cognitive self-discipline, concentration, and meditation. In particular, Steiner believed a person's spiritual development could occur only after a period of moral development. In 1912, Steiner broke away from the Theosophical Society to found an independent group, which he named the Anthroposophical Society. After World War I, members of the young society began applying Steiner's ideas to create cultural movements in areas such as traditional and special education, farming, and medicine. By 1923, a schism had formed between older members, focused on inner development, and younger members eager to become active in contemporary social transformations. In response, Steiner attempted to bridge the gap by establishing an overall School for Spiritual Science. As a spiritual basis for the reborn movement, Steiner wrote a Foundation Stone Meditation which remains a central touchstone of anthroposophical ideas. Steiner died just over a year later, in 1925. The Second World War temporarily hindered the anthroposophical movement in most of Continental Europe, as the Anthroposophical Society and most of its practical counter-cultural applications were banned by the Nazi government. Though at least one prominent member of the Nazi Party, Rudolf Hess, was a strong supporter of anthroposophy, very few anthroposophists belonged to the National Socialist Party. In reality, Steiner had both enemies and loyal supporters in the upper echelons of the Nazi regime. Staudenmaier speaks of the "polycratic party-state apparatus", so Nazism's approach to Anthroposophy was not characterized by monolithic ideological unity. When Hess flew to the UK and was imprisoned, their most powerful protector was gone, but Anthroposophists were still not left without supporters among higher-placed Nazis. The Third Reich had banned almost all esoteric organizations, pretending that these are controlled by Jews. The truth was that while Anthroposophists complained of bad press, they were to a surprising extent let be by the Nazi regime, "including outspokenly supportive pieces in the Völkischer Beobachter". Ideological purists from Sicherheitsdienst argued largely in vain against Anthroposophy. According to Staudenmaier, "The prospect of unmitigated persecution was held at bay for years in a tenuous truce between pro-anthroposophical and anti-anthroposophical Nazi factions." According to Hans Büchenbacher, an anthroposophist, the Secretary General of the General Anthroposophical Society, Guenther Wachsmuth, as well as Steiner's widow, Marie Steiner, were “completely pro-Nazi.” Marie Steiner-von Sivers, Guenther Wachsmuth, and Albert Steffen, had publicly expressed sympathy for the Nazi regime since its beginnings; led by such sympathies of their leadership, the Swiss and German Anthroposophical organizations chose for a path conflating accommodation with collaboration, which in the end ensured that while the Nazi regime hunted the esoteric organizations, Gentile Anthroposophists from Nazi Germany and countries occupied by it were let be to a surprising extent. Of course they had some setbacks from the enemies of Anthroposophy among the upper echelons of the Nazi regime, but Anthroposophists also had loyal supporters among them, so overall Gentile Anthroposophists were not badly hit by the Nazi regime. By 2007, national branches of the Anthroposophical Society had been established in fifty countries and about 10,000 institutions around the world were working on the basis of anthroposophical ideas. Etymology and earlier uses of the word Anthroposophy is an amalgam of the Greek terms ( 'human') and ( 'wisdom'). An early English usage is recorded by Nathan Bailey (1742) as meaning "the knowledge of the nature of man." The first known use of the term anthroposophy occurs within Arbatel de magia veterum, summum sapientiae studium, a book published anonymously in 1575 and attributed to Heinrich Cornelius Agrippa. The work describes anthroposophy (as well as theosophy) variously as an understanding of goodness, nature, or human affairs. In 1648, the Welsh philosopher Thomas Vaughan published his Anthroposophia Theomagica, or a discourse of the nature of man and his state after death. The term began to appear with some frequency in philosophical works of the mid- and late-nineteenth century. In the early part of that century, Ignaz Troxler used the term anthroposophy to refer to philosophy deepened to self-knowledge, which he suggested allows deeper knowledge of nature as well. He spoke of human nature as a mystical unity of God and world. Immanuel Hermann Fichte used the term anthroposophy to refer to "rigorous human self-knowledge," achievable through thorough comprehension of the human spirit and of the working of God in this spirit, in his 1856 work Anthropology: The Study of the Human Soul. In 1872, the philosopher of religion Gideon Spicker used the term anthroposophy to refer to self-knowledge that would unite God and world: "the true study of the human being is the human being, and philosophy's highest aim is self-knowledge, or Anthroposophy." In 1882, the philosopher Robert Zimmermann published the treatise, "An Outline of Anthroposophy: Proposal for a System of Idealism on a Realistic Basis," proposing that idealistic philosophy should employ logical thinking to extend empirical experience. Steiner attended lectures by Zimmermann at the University of Vienna in the early 1880s, thus at the time of this book's publication. In the early 1900s, Steiner began using the term anthroposophy (i.e. human wisdom) as an alternative to the term theosophy (i.e. divine wisdom). Central ideas Spiritual knowledge and freedom Anthroposophical proponents aim to extend the clarity of the scientific method to phenomena of human soul-life and spiritual experiences. Steiner believed this required developing new faculties of objective spiritual perception, which he maintained was still possible for contemporary humans. The steps of this process of inner development he identified as consciously achieved imagination, inspiration, and intuition. Steiner believed results of this form of spiritual research should be expressed in a way that can be understood and evaluated on the same basis as the results of natural science. Steiner hoped to form a spiritual movement that would free the individual from any external authority. For Steiner, the human capacity for rational thought would allow individuals to comprehend spiritual research on their own and bypass the danger of dependency on an authority such as himself. Steiner contrasted the anthroposophical approach with both conventional mysticism, which he considered lacking the clarity necessary for exact knowledge, and natural science, which he considered arbitrarily limited to what can be seen, heard, or felt with the outward senses. Nature of the human being In Theosophy, Steiner suggested that human beings unite a physical body of substances gathered from and returning to the inorganic world; a life body (also called the etheric body), in common with all living creatures (including plants); a bearer of sentience or consciousness (also called the astral body), in common with all animals; and the ego, which anchors the faculty of self-awareness unique to human beings. Anthroposophy describes a broad evolution of human consciousness. Early stages of human evolution possess an intuitive perception of reality, including a clairvoyant perception of spiritual realities. Humanity has progressively evolved an increasing reliance on intellectual faculties and a corresponding loss of intuitive or clairvoyant experiences, which have become atavistic. The increasing intellectualization of consciousness, initially a progressive direction of evolution, has led to an excessive reliance on abstraction and a loss of contact with both natural and spiritual realities. However, to go further requires new capacities that combine the clarity of intellectual thought with the imagination and with consciously achieved inspiration and intuitive insights. Anthroposophy speaks of the reincarnation of the human spirit: that the human being passes between stages of existence, incarnating into an earthly body, living on earth, leaving the body behind, and entering into the spiritual worlds before returning to be born again into a new life on earth. After the death of the physical body, the human spirit recapitulates the past life, perceiving its events as they were experienced by the objects of its actions. A complex transformation takes place between the review of the past life and the preparation for the next life. The individual's karmic condition eventually leads to a choice of parents, physical body, disposition, and capacities that provide the challenges and opportunities that further development requires, which includes karmically chosen tasks for the future life. Steiner described some conditions that determine the interdependence of a person's lives, or karma. Evolution The anthroposophical view of evolution considers all animals to have evolved from an early, unspecialized form. As the least specialized animal, human beings have maintained the closest connection to the archetypal form; contrary to the Darwinian conception of human evolution, all other animals devolve from this archetype. The spiritual archetype originally created by spiritual beings was devoid of physical substance; only later did this descend into material existence on Earth. In this view, human evolution has accompanied the Earth's evolution throughout the existence of the Earth. Anthroposophy adapted Theosophy's complex system of cycles of world development and human evolution. The evolution of the world is said to have occurred in cycles. The first phase of the world consisted only of heat. In the second phase, a more active condition, light, and a more condensed, gaseous state separate out from the heat. In the third phase, a fluid state arose, as well as a sounding, forming energy. In the fourth (current) phase, solid physical matter first exists. This process is said to have been accompanied by an evolution of consciousness which led up to present human culture. Ethics The anthroposophical view is that good is found in the balance between two polar influences on world and human evolution. These are often described through their mythological embodiments as spiritual adversaries which endeavour to tempt and corrupt humanity, Lucifer and his counterpart Ahriman. These have both positive and negative aspects. Lucifer is the light spirit, which "plays on human pride and offers the delusion of divinity", but also motivates creativity and spirituality; Ahriman is the dark spirit that tempts human beings to "...deny [their] link with divinity and to live entirely on the material plane", but that also stimulates intellectuality and technology. Both figures exert a negative effect on humanity when their influence becomes misplaced or one-sided, yet their influences are necessary for human freedom to unfold. Each human being has the task to find a balance between these opposing influences, and each is helped in this task by the mediation of the Representative of Humanity, also known as the Christ being, a spiritual entity who stands between and harmonizes the two extremes. Claimed applications Steiner/Waldorf education This is a pedagogical movement with over 1000 Steiner or Waldorf schools (the latter name stems from the first such school, founded in Stuttgart in 1919) located in some 60 countries; the great majority of these are independent (private) schools. Sixteen of the schools have been affiliated with the United Nations' UNESCO Associated Schools Project Network, which sponsors education projects that foster improved quality of education throughout the world. Waldorf schools receive full or partial governmental funding in some European nations, Australia and in parts of the United States (as Waldorf method public or charter schools) and Canada. The schools have been founded in a variety of communities: for example in the favelas of São Paulo to wealthy suburbs of major cities; in India, Egypt, Australia, the Netherlands, Mexico and South Africa. Though most of the early Waldorf schools were teacher-founded, the schools today are usually initiated and later supported by a parent community. Waldorf schools are among the most visible anthroposophical institutions. Biodynamic agriculture Biodynamic agriculture, is a form of alternative agriculture based on pseudo-scientific and esoteric concepts. It is also the first intentional form of organic farming, began in 1924, when Rudolf Steiner gave a series of lectures published in English as The Agriculture Course. Steiner is considered one of the founders of the modern organic farming movement. Anthroposophical medicine Anthroposophical medicine is a form of alternative medicine based on pseudoscientific and occult notions rather than in science-based medicine. Most anthroposophic medical preparations are highly diluted, like homeopathic remedies, while harmless in of themselves, using them in place of conventional medicine to treat illness is ineffective and risks adverse consequences. One of the most studied applications has been the use of mistletoe extracts in cancer therapy, but research has found no evidence of benefit. Special needs education and services In 1922, Ita Wegman founded an anthroposophical center for special needs education, the Sonnenhof, in Switzerland. In 1940, Karl König founded the Camphill Movement in Scotland. The latter in particular has spread widely, and there are now over a hundred Camphill communities and other anthroposophical homes for children and adults in need of special care in about 22 countries around the world. Both Karl König, Thomas Weihs and others have written extensively on these ideas underlying Special education. Architecture Steiner designed around thirteen buildings in an organic—expressionist architectural style. Foremost among these are his designs for the two Goetheanum buildings in Dornach, Switzerland. Thousands of further buildings have been built by later generations of anthroposophic architects. Architects who have been strongly influenced by the anthroposophic style include Imre Makovecz in Hungary, Hans Scharoun and Joachim Eble in Germany, Erik Asmussen in Sweden, Kenji Imai in Japan, Thomas Rau, Anton Alberts and Max van Huut in the Netherlands, Christopher Day and Camphill Architects in the UK, Thompson and Rose in America, Denis Bowman in Canada, and Walter Burley Griffin and Gregory Burgess in Australia.<ref>Raab, Klingborg and Fånt, Eloquent Concrete, London: 1979.</ref>Sokolina, Anna, "The Goetheanum Culture in Modern Architecture."

Moscow: MARKHI, 2014. 536p. ING House in Amsterdam is a contemporary building by an anthroposophical architect which has received awards for its ecological design and approach to a self-sustaining ecology as an autonomous building and example of sustainable architecture. Eurythmy Together with Marie von Sivers, Steiner developed eurythmy, a performance art combining dance, speech, and music.Earl j. Ogletree, Eurythmy: A therapeutic art of movement Journal of Special Education Fall 1976 vol. 10 no. 3 305-319 Social finance and entrepreneurship Around the world today are a number of banks, companies, charities, and schools for developing co-operative forms of business using Steiner's ideas about economic associations, aiming at harmonious and socially responsible roles in the world economy. The first anthroposophic bank was the Gemeinschaftsbank für Leihen und Schenken in Bochum, Germany, founded in 1974. Socially responsible banks founded out of anthroposophy include Triodos Bank, founded in the Netherlands in 1980 and also active in the UK, Germany, Belgium, Spain and France. Other examples include Cultura Sparebank which dates from 1982 when a group of Norwegian anthroposophists began an initiative for ethical banking but only began to operate as a savings bank in Norway in the late 90s, La Nef in France and RSF Social Financein San Francisco. Harvard Business School historian Geoffrey Jones traced the considerable impact both Steiner and later anthroposophical entrepreneurs had on the creation of many businesses in organic food, ecological architecture and sustainable finance. Organizational development, counselling and biography work Bernard Lievegoed, a psychiatrist, founded a new method of individual and institutional development oriented towards humanizing organizations and linked with Steiner's ideas of the threefold social order. This work is represented by the NPI Institute for Organizational Development in the Netherlands and sister organizations in many other countries. Various forms of biographic and counselling work have been developed on the basis of anthroposophy. Speech and drama There are also anthroposophical movements to renew speech and drama, the most important of which are based in the work of Marie Steiner-von Sivers (speech formation, also known as Creative Speech) and the Chekhov Method originated by Michael Chekhov (nephew of Anton Chekhov). Art Anthroposophic painting, a style inspired by Rudolf Steiner, featured prominently in the first Goetheanum's cupola. The technique frequently begins by filling the surface to be painted with color, out of which forms are gradually developed, often images with symbolic-spiritual significance. Paints that allow for many transparent layers are preferred, and often these are derived from plant materials. Rudolf Steiner appointed the English sculptor Edith Maryon as head of the School of Fine Art at the Goetheanum. Together they carved the 9-metre tall sculpture titled The Representative of Humanity, on display at the Goetheanum. Other Phenomenological approaches to science, pseudo-scientific ideas based on Goethe's philosophy of nature. New approaches to painting and sculpture. John Wilkes' fountain-like flowforms, sculptural forms that guide water into rhythmic movement for the purposes of decoration. Social goals For a period after World War I, Steiner was extremely active and well known in Germany, in part because he lectured widely proposing social reforms. Steiner was a sharp critic of nationalism, which he saw as outdated, and a proponent of achieving social solidarity through individual freedom. A petition proposing a radical change in the German constitution and expressing his basic social ideas (signed by Herman Hesse, among others) was widely circulated. His main book on social reform is Toward Social Renewal. Anthroposophy continues to aim at reforming society through maintaining and strengthening the independence of the spheres of cultural life, human rights and the economy. It emphasizes a particular ideal in each of these three realms of society: Liberty in cultural life Equality of rights, the sphere of legislation Fraternity in the economic sphere Esoteric path Paths of spiritual development According to Steiner, a real spiritual world exists, evolving along with the material one. Steiner held that the spiritual world can be researched in the right circumstances through direct experience, by persons practicing rigorous forms of ethical and cognitive self-discipline. Steiner described many exercises he said were suited to strengthening such self-discipline; the most complete exposition of these is found in his book How To Know Higher Worlds. The aim of these exercises is to develop higher levels of consciousness through meditation and observation. Details about the spiritual world, Steiner suggested, could on such a basis be discovered and reported, though no more infallibly than the results of natural science. Steiner regarded his research reports as being important aids to others seeking to enter into spiritual experience. He suggested that a combination of spiritual exercises (for example, concentrating on an object such as a seed), moral development (control of thought, feelings and will combined with openness, tolerance and flexibility) and familiarity with other spiritual researchers' results would best further an individual's spiritual development. He consistently emphasised that any inner, spiritual practice should be undertaken in such a way as not to interfere with one's responsibilities in outer life. Steiner distinguished between what he considered were true and false paths of spiritual investigation. In anthroposophy, artistic expression is also treated as a potentially valuable bridge between spiritual and material reality. Prerequisites to and stages of inner development Steiner's stated prerequisites to beginning on a spiritual path include a willingness to take up serious cognitive studies, a respect for factual evidence, and a responsible attitude. Central to progress on the path itself is a harmonious cultivation of the following qualities: Control over one's own thinking Control over one's will Composure Positivity Impartiality Steiner sees meditation as a concentration and enhancement of the power of thought. By focusing consciously on an idea, feeling or intention the meditant seeks to arrive at pure thinking, a state exemplified by but not confined to pure mathematics. In Steiner's view, conventional sensory-material knowledge is achieved through relating perception and concepts. The anthroposophic path of esoteric training articulates three further stages of supersensory knowledge, which do not necessarily follow strictly sequentially in any single individual's spiritual progress.Stein, W. J., Die moderne naturwissenschaftliche Vorstellungsart und die Weltanschauung Goethes, wie sie Rudolf Steiner vertritt, reprinted in Meyer, Thomas, W.J. Stein / Rudolf Steiner, pp. 267–75; 256–7. By focusing on symbolic patterns, images, and poetic mantras, the meditant can achieve consciously directed Imaginations that allow sensory phenomena to appear as the expression of underlying beings of a soul-spiritual nature. By transcending such imaginative pictures, the meditant can become conscious of the meditative activity itself, which leads to experiences of expressions of soul-spiritual beings unmediated by sensory phenomena or qualities. Steiner calls this stage Inspiration. By intensifying the will-forces through exercises such as a chronologically reversed review of the day's events, the meditant can achieve a further stage of inner independence from sensory experience, leading to direct contact, and even union, with spiritual beings ("Intuition") without loss of individual awareness. Spiritual exercises Steiner described numerous exercises he believed would bring spiritual development; other anthroposophists have added many others. A central principle is that "for every step in spiritual perception, three steps are to be taken in moral development." According to Steiner, moral development reveals the extent to which one has achieved control over one's inner life and can exercise it in harmony with the spiritual life of other people; it shows the real progress in spiritual development, the fruits of which are given in spiritual perception. It also guarantees the capacity to distinguish between false perceptions or illusions (which are possible in perceptions of both the outer world and the inner world) and true perceptions: i.e., the capacity to distinguish in any perception between the influence of subjective elements (i.e., viewpoint) and objective reality. Place in Western philosophy Steiner built upon Goethe's conception of an imaginative power capable of synthesizing the sense-perceptible form of a thing (an image of its outer appearance) and the concept we have of that thing (an image of its inner structure or nature). Steiner added to this the conception that a further step in the development of thinking is possible when the thinker observes his or her own thought processes. "The organ of observation and the observed thought process are then identical, so that the condition thus arrived at is simultaneously one of perception through thinking and one of thought through perception." Thus, in Steiner's view, we can overcome the subject-object divide through inner activity, even though all human experience begins by being conditioned by it. In this connection, Steiner examines the step from thinking determined by outer impressions to what he calls sense-free thinking. He characterizes thoughts he considers without sensory content, such as mathematical or logical thoughts, as free deeds. Steiner believed he had thus located the origin of free will in our thinking, and in particular in sense-free thinking. Some of the epistemic basis for Steiner's later anthroposophical work is contained in the seminal work, Philosophy of Freedom. In his early works, Steiner sought to overcome what he perceived as the dualism of Cartesian idealism and Kantian subjectivism by developing Goethe's conception of the human being as a natural-supernatural entity, that is: natural in that humanity is a product of nature, supernatural in that through our conceptual powers we extend nature's realm, allowing it to achieve a reflective capacity in us as philosophy, art and science. Steiner was one of the first European philosophers to overcome the subject-object split in Western thought. Though not well known among philosophers, his philosophical work was taken up by Owen Barfield (and through him influenced the Inklings, an Oxford group of Christian writers that included J. R. R. Tolkien and C. S. Lewis). Christian and Jewish mystical thought have also influenced the development of anthroposophy.Paddock, F. and Spiegler, M., Judaism and Anthroposophy, 2003 Union of science and spirit Steiner believed in the possibility of applying the clarity of scientific thinking to spiritual experience, which he saw as deriving from an objectively existing spiritual world. Steiner identified mathematics, which attains certainty through thinking itself, thus through inner experience rather than empirical observation, as the basis of his epistemology of spiritual experience. Relationship to religion Christ as the center of earthly evolution Steiner's writing, though appreciative of all religions and cultural developments, emphasizes Western tradition as having evolved to meet contemporary needs. He describes Christ and his mission on earth of bringing individuated consciousness as having a particularly important place in human evolution, whereby: Christianity has evolved out of previous religions; The being which manifests in Christianity also manifests in all faiths and religions, and each religion is valid and true for the time and cultural context in which it was born; All historical forms of Christianity need to be transformed considerably to meet the continuing evolution of humanity. Thus, anthroposophy considers there to be a being who unifies all religions, and who is not represented by any particular religious faith. This being is, according to Steiner, not only the Redeemer of the Fall from Paradise, but also the unique pivot and meaning of earth's evolutionary processes and of human history. To describe this being, Steiner periodically used terms such as the "Representative of Humanity" or the "good spirit" rather than any denominational term. Divergence from conventional Christian thought Steiner's views of Christianity diverge from conventional Christian thought in key places, and include gnostic elements: One central point of divergence is Steiner's views on reincarnation and karma. Steiner differentiated three contemporary paths by which he believed it possible to arrive at Christ: Through heart-felt experiences of the Gospels; Steiner described this as the historically dominant path, but becoming less important in the future. Through inner experiences of a spiritual reality; this Steiner regarded as increasingly the path of spiritual or religious seekers today. Through initiatory experiences whereby the reality of Christ's death and resurrection are experienced; Steiner believed this is the path people will increasingly take. Steiner also believed that there were two different Jesus children involved in the Incarnation of the Christ: one child descended from Solomon, as described in the Gospel of Matthew, the other child from Nathan, as described in the Gospel of Luke. (The genealogies given in the two gospels diverge some thirty generations before Jesus' birth, and 'Jesus' was a common name in biblical times.) His view of the second coming of Christ is also unusual; he suggested that this would not be a physical reappearance, but that the Christ being would become manifest in non-physical form, visible to spiritual vision and apparent in community life for increasing numbers of people beginning around the year 1933. He emphasized his belief that in the future humanity would need to be able to recognize the Spirit of Love in all its genuine forms, regardless of what name would be used to describe this being. He also warned that the traditional name of the Christ might be misused, and the true essence of this being of love ignored. According to Jane Gilmer, "Jung and Steiner were both versed in ancient gnosis and both envisioned a paradigmatic shift in the way it was delivered." As Gilles Quispel put it, "After all, Theosophy is a pagan, Anthroposophy a Christian form of modern Gnosis." Maria Carlson stated "Theosophy and Anthroposophy are fundamentally Gnostic systems in that they posit the dualism of Spirit and Matter." R. McL. Wilson in The Oxford Companion to the Bible agrees that Steiner and Anthroposophy are under the influence of gnosticism. Judaism Rudolf Steiner wrote and lectured on Judaism and Jewish issues over much of his adult life. He was a fierce opponent of popular antisemitism, but asserted that there was no justification for the existence of Judaism and Jewish culture in the modern world, a radical assimilationist perspective which saw the Jews completely integrating into the larger society.Peter Staudenmeier, "Rudolf Steiner and the Jewish Question" , Leo Baeck Institute Yearbook, Vol. 50, No. 1 (2005): 127-147. He also supported Émile Zola's position in the Dreyfus affair. Steiner emphasized Judaism's central importance to the constitution of the modern era in the West but suggested that to appreciate the spirituality of the future it would need to overcome its tendency toward abstraction. Steiner has financed the publication of the book Die Entente-Freimaurerei und der Weltkrieg (1919) by ; Steiner also wrote the foreword for the book, partly based upon his own ideas. The publication comprised a conspiracy theory according to whom World War I was a consequence of a collusion of Freemasons and Jews - still favorite scapegoats of the conspiracy theorists - their purpose being the destruction of Germany. The writing was later enthusiastically received by the Nazi Party. According to Dick Taverne Steiner was a Nazi (i.e. a member of the NSDAP). In his later life, Steiner was accused by the Nazis of being a Jew, and Adolf Hitler called anthroposophy "Jewish methods". The anthroposophical institutions in Germany were banned during Nazi rule and several anthroposophists sent to concentration camps.Lorenzo Ravagli, Unter Hammer und Hakenkreuz: Der völkisch-nationalsozialistische Kampf gegen die Anthroposophie, Verlag Freies Geistesleben, Important early anthroposophists who were Jewish included two central members on the executive boards of the precursors to the modern Anthroposophical Society, and Karl König, the founder of the Camphill movement, who had converted to Christianity. Martin Buber and Hugo Bergmann, who viewed Steiner's social ideas as a solution to the Arab–Jewish conflict, were also influenced by anthroposophy. There are numerous anthroposophical organisations in Israel, including the anthroposophical kibbutz Harduf, founded by Jesaiah Ben-Aharon, forty Waldorf kindergartens and seventeen Waldorf schools (stand as of 2018). A number of these organizations are striving to foster positive relationships between the Arab and Jewish populations: The Harduf Waldorf school includes both Jewish and Arab faculty and students, and has extensive contact with the surrounding Arab communities, while the first joint Arab-Jewish kindergarten was a Waldorf program in Hilf near Haifa. Christian Community Towards the end of Steiner's life, a group of theology students (primarily Lutheran, with some Roman Catholic members) approached Steiner for help in reviving Christianity, in particular "to bridge the widening gulf between modern science and the world of spirit". They approached a notable Lutheran pastor, Friedrich Rittelmeyer, who was already working with Steiner's ideas, to join their efforts. Out of their co-operative endeavor, the Movement for Religious Renewal, now generally known as The Christian Community, was born. Steiner emphasized that he considered this movement, and his role in creating it, to be independent of his anthroposophical work, as he wished anthroposophy to be independent of any particular religion or religious denomination. Reception Anthroposophy's supporters include Saul Bellow, Selma Lagerlöf, Andrei Bely, Joseph Beuys, Owen Barfield, architect Walter Burley Griffin, Wassily Kandinsky, Andrei Tarkovsky, Bruno Walter, Right Livelihood Award winners Sir George Trevelyan, and Ibrahim Abouleish, and child psychiatrist Eva Frommer.Fiona Subotsky, Eva Frommer (Obituary) , 29 April 2005. The historian of religion Olav Hammer has termed anthroposophy "the most important esoteric society in European history." However authors, scientists, and physicians including Michael Shermer, Michael Ruse, Edzard Ernst, David Gorski, and Simon Singh have criticized anthroposophy's application in the areas of medicine, biology, agriculture, and education to be dangerous and pseudoscientific. Others including former Waldorf pupil Dan Dugan and historian Geoffrey Ahern have criticized anthroposophy itself as a dangerous quasi-religious movement that is fundamentally anti-rational and anti-scientific. Scientific basis Though Rudolf Steiner studied natural science at the Vienna Technical University at the undergraduate level, his doctorate was in epistemology and very little of his work is directly concerned with the empirical sciences. In his mature work, when he did refer to science it was often to present phenomenological or Goethean science as an alternative to what he considered the materialistic science of his contemporaries. Steiner's primary interest was in applying the methodology of science to realms of inner experience and the spiritual worlds (his appreciation that the essence of science is its method of inquiry is unusual among esotericists), and Steiner called anthroposophy Geisteswissenschaft'' (science of the mind, cultural/spiritual science), a term generally used in German to refer to the humanities and social sciences. Whether this is a sufficient basis for anthroposophy to be considered a spiritual science has been a matter of controversy. As Freda Easton explained in her study of Waldorf schools, "Whether one accepts anthroposophy as a science depends upon whether one accepts Steiner's interpretation of a science that extends the consciousness and capacity of human beings to experience their inner spiritual world." Sven Ove Hansson has disputed anthroposophy's claim to a scientific basis, stating that its ideas are not empirically derived and neither reproducible nor testable. Carlo Willmann points out that as, on its own terms, anthroposophical methodology offers no possibility of being falsified except through its own procedures of spiritual investigation, no intersubjective validation is possible by conventional scientific methods; it thus cannot stand up to empiricist critics. Peter Schneider describes such objections as untenable, asserting that if a non-sensory, non-physical realm exists, then according to Steiner the experiences of pure thinking possible within the normal realm of consciousness would already be experiences of that, and it would be impossible to exclude the possibility of empirically grounded experiences of other supersensory content. Olav Hammer suggests that anthroposophy carries scientism "to lengths unparalleled in any other Esoteric position" due to its dependence upon claims of clairvoyant experience, its subsuming natural science under "spiritual science." Hammer also asserts that the development of what she calls "fringe" sciences such as anthroposophic medicine and biodynamic agriculture are justified partly on the basis of the ethical and ecological values they promote, rather than purely on a scientific basis. Though Steiner saw that spiritual vision itself is difficult for others to achieve, he recommended open-mindedly exploring and rationally testing the results of such research; he also urged others to follow a spiritual training that would allow them directly to apply his methods to achieve comparable results. Anthony Storr stated about Rudolf Steiner's Anthroposophy: "His belief system is so eccentric, so unsupported by evidence, so manifestly bizarre, that rational skeptics are bound to consider it delusional... But, whereas Einstein's way of perceiving the world by thought became confirmed by experiment and mathematical proof, Steiner's remained intensely subjective and insusceptible of objective confirmation." According to Dan Dugan, Steiner was a champion of the following pseudoscientific claims, also championed by Waldorf schools: wrong color theory; obtuse criticism of the theory of relativity; weird ideas about motions of the planets; supporting vitalism; doubting germ theory; weird approach to physiological systems; "the heart is not a pump". Religious nature As an explicitly spiritual movement, anthroposophy has sometimes been called a religious philosophy. In 1998 People for Legal and Non-Sectarian Schools (PLANS) started a lawsuit alleging that anthroposophy is a religion for Establishment Clause purposes and therefore several California school districts should not be chartering Waldorf schools; the lawsuit was dismissed in 2012 for failure to show anthroposophy was a religion. In 2000, a French court ruled that a government minister's description of anthroposophy as a cult was defamatory. Scholars claim Anthroposophy is influenced by Christian Gnosticism. The Catholic Church did in 1919 issue an edict classifying Anthroposophy as "a neognostic heresy" despite the fact that Steiner "very well respected the distinctions on which Catholic dogma insists". Postwar relations however have been much warmer with Karol Wojtyla (later coronated Pope John Paul II) enjoying close relationship with Anthroposophical insight and community, even publishing literary forward for friend and mentor M. Kotlarczyk in addition. Meanwhile the Steiner-inspired Christian Community congregations as mentioned in the Catholic Encyclopedia are received ecumenically as recognized and genuine Christian believers worldwide. Despite this, some Baptist and mainstream academical heresiologists still appear inclined to agree with the more narrow prior edict of 1919 on dogma and the Lutheran (Missouri Sinod) apologist and heresiologist Eldon K. Winker asserts Steiner's Christology as being very similar to Cerinthus. Steiner did perceive "a distinction between the human person Jesus, and Christ as the divine Logos", which could be construed as Gnostic but not docetic. Steiner-inspired Christian Community congregations globally were among the first congregations and denominations to include both female and gay pastors as early as the 1920's - in contrast with the range of other Christian denominations in their times, and well beyond. Statements on race Some anthroposophical ideas challenged the National Socialist racialist and nationalistic agenda. In contrast, some American educators have criticized Waldorf schools for failing to equally include the fables and myths of all cultures, instead favoring European stories over African ones. From the mid-1930s on, National Socialist ideologues attacked the anthroposophical worldview as being opposed to Nazi racist and nationalistic principles; anthroposophy considered "Blood, Race and Folk" as primitive instincts that must be overcome. An academic analysis of the educational approach in public schools noted that "[A] naive version of the evolution of consciousness, a theory foundational to both Steiner's anthroposophy and Waldorf education, sometimes places one race below another in one or another dimension of development. It is easy to imagine why there are disputes [...] about Waldorf educators' insisting on teaching Norse tales and Greek myths to the exclusion of African modes of discourse." In response to such critiques, the Anthroposophical Society in America published in 1998 a statement clarifying its stance: We explicitly reject any racial theory that may be construed to be part of Rudolf Steiner's writings. The Anthroposophical Society in America is an open, public society and it rejects any purported spiritual or scientific theory on the basis of which the alleged superiority of one race is justified at the expense of another race. Tommy Wieringa, a Dutch writer who grew among Anthroposophists, commenting upon an essay by the Anthroposophist , he wrote "It was a meeting of old acquaintances: Nazi leaders such as Rudolf Hess and Heinrich Himmler already recognized a kindred spirit in Rudolf Steiner, with his theories about racial purity, esoteric medicine and biodynamic agriculture." Adolf Hitler personally called on the Nazis to declare "war against Steiner" and he immediately had to flee to Switzerland, never to set foot in Germany again. The racism of Anthroposophy is spiritual and paternalistic (i.e. benevolent), while the racism of fascism is materialistic and often malign. Olav Hammer, university professor expert in new religious movements and Western esotericism, confirms that now the racist and anti-Semitic character of Steiner's teachings can no longer be denied, even if that is "spiritual racism". Imperfect as critics assert his writings and work may be, both critics and proponents alike nevertheless acknowledge his extensive body of anti-racist statements, often far ahead of his predecessors and even contemporaries who are still commonly cited in academia and beyond in modern times.

Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by the American National Standards Institute and ITU-T (formerly CCITT) for digital transmission of multiple types of traffic. ATM was developed to meet the needs of the Broadband Integrated Services Digital Network as defined in the late 1980s, and designed to integrate telecommunication networks. It can handle both traditional high-throughput data traffic and real-time, low-latency content such as telephony (voice) and video. ATM provides functionality that uses features of circuit switching and packet switching networks by using asynchronous time-division multiplexing. In the OSI reference model data link layer (layer 2), the basic transfer units are called frames. In ATM these frames are of a fixed length (53 octets) called cells. This differs from approaches such as Internet Protocol (IP) (OSI layer 3) or Ethernet (also layer 2) that use variable-sized packets or frames. ATM uses a connection-oriented model in which a virtual circuit must be established between two endpoints before the data exchange begins. These virtual circuits may be either permanent (dedicated connections that are usually preconfigured by the service provider), or switched (set up on a per-call basis using signaling and disconnected when the call is terminated). The ATM network reference model approximately maps to the three lowest layers of the OSI model: physical layer, data link layer, and network layer. ATM is a core protocol used in the synchronous optical networking and synchronous digital hierarchy (SONET/SDH) backbone of the public switched telephone network and in the Integrated Services Digital Network (ISDN) but has largely been superseded in favor of next-generation networks based on IP technology. Wireless and mobile ATM never established a significant foothold. Protocol architecture To minimize queuing delay and packet delay variation (PDV), all ATM cells are the same small size. Reduction of PDV is particularly important when carrying voice traffic, because the conversion of digitized voice into an analog audio signal is an inherently real-time process. The decoder needs an evenly spaced stream of data items. At the time of the design of ATM, 155 Mbit/s synchronous digital hierarchy with 135 Mbit/s payload was considered a fast optical network link, and many plesiochronous digital hierarchy links in the digital network were considerably slower, ranging from 1.544 to 45 Mbit/s in the US, and 2 to 34 Mbit/s in Europe. At 155 Mbit/s, a typical full-length 1,500 byte Ethernet frame would take 77.42 µs to transmit. On a lower-speed 1.544 Mbit/s T1 line, the same packet would take up to 7.8 milliseconds. A queuing delay induced by several such data packets might exceed the figure of 7.8 ms several times over. This was considered unacceptable for speech traffic. The design of ATM aimed for a low-jitter network interface. Cells were introduced to provide short queuing delays while continuing to support datagram traffic. ATM broke up all packets, data, and voice streams into 48-byte chunks, adding a 5-byte routing header to each one so that they could be reassembled later. The choice of 48 bytes was political rather than technical. When the CCITT (now ITU-T) was standardizing ATM, parties from the United States wanted a 64-byte payload because this was felt to be a good compromise between larger payloads optimized for data transmission and shorter payloads optimized for real-time applications like voice. Parties from Europe wanted 32-byte payloads because the small size (and therefore short transmission times) improve performance for voice applications. Most of the European parties eventually came around to the arguments made by the Americans, but France and a few others held out for a shorter cell length. With 32 bytes, France would have been able to implement an ATM-based voice network with calls from one end of France to the other requiring no echo cancellation. 48 bytes (plus 5 header bytes = 53) was chosen as a compromise between the two sides. 5-byte headers were chosen because it was thought that 10% of the payload was the maximum price to pay for routing information. ATM multiplexed these 53-byte cells instead of packets which reduced worst-case cell contention jitter by a factor of almost 30, reducing the need for echo cancellers. Cell structure An ATM cell consists of a 5-byte header and a 48-byte payload. ATM defines two different cell formats: user–network interface (UNI) and network–network interface (NNI). Most ATM links use UNI cell format. GFC The generic flow control (GFC) field is a 4-bit field that was originally added to support the connection of ATM networks to shared access networks such as a distributed queue dual bus (DQDB) ring. The GFC field was designed to give the User-Network Interface (UNI) 4 bits in which to negotiate multiplexing and flow control among the cells of various ATM connections. However, the use and exact values of the GFC field have not been standardized, and the field is always set to 0000. VPI Virtual path identifier (8 bits UNI, or 12 bits NNI) VCI Virtual channel identifier (16 bits) PT Payload type (3 bits) Bit 3 (msbit): Network management cell. If 0, user data cell and the following apply: Bit 2: Explicit forward congestion indication (EFCI); 1 = network congestion experienced Bit 1 (lsbit): ATM user-to-user (AAU) bit. Used by AAL5 to indicate packet boundaries. CLP Cell loss priority (1-bit) HEC Header error control (8-bit CRC, polynomial = X8 + X2 + X + 1) ATM uses the PT field to designate various special kinds of cells for operations, administration and management (OAM) purposes, and to delineate packet boundaries in some ATM adaptation layers (AAL). If the most significant bit (MSB) of the PT field is 0, this is a user data cell, and the other two bits are used to indicate network congestion and as a general-purpose header bit available for ATM adaptation layers. If the MSB is 1, this is a management cell, and the other two bits indicate the type: network management segment, network management end-to-end, resource management, and reserved for future use. Several ATM link protocols use the HEC field to drive a CRC-based framing algorithm, which allows locating the ATM cells with no overhead beyond what is otherwise needed for header protection. The 8-bit CRC is used to correct single-bit header errors and detect multi-bit header errors. When multi-bit header errors are detected, the current and subsequent cells are dropped until a cell with no header errors is found. A UNI cell reserves the GFC field for a local flow control and sub-multiplexing system between users. This was intended to allow several terminals to share a single network connection in the same way that two ISDN phones can share a single basic rate ISDN connection. All four GFC bits must be zero by default. The NNI cell format replicates the UNI format almost exactly, except that the 4-bit GFC field is re-allocated to the VPI field, extending the VPI to 12 bits. Thus, a single NNI ATM interconnection is capable of addressing almost 212 VPs of up to almost 216 VCs each. Service types ATM supports different types of services via AALs. Standardized AALs include AAL1, AAL2, and AAL5, and the rarely used AAL3 and AAL4. AAL1 is used for constant bit rate (CBR) services and circuit emulation. Synchronization is also maintained at AAL1. AAL2 through AAL4 are used for variable bitrate (VBR) services, and AAL5 for data. Which AAL is in use for a given cell is not encoded in the cell. Instead, it is negotiated by or configured at the endpoints on a per-virtual-connection basis. Following the initial design of ATM, networks have become much faster. A 1500 byte (12000-bit) full-size Ethernet frame takes only 1.2 µs to transmit on a 10 Gbit/s network, reducing the motivation for small cells to reduce jitter due to contention. The increased link speeds by themselves do not eliminate jitter due to queuing. ATM provides a useful ability to carry multiple logical circuits on a single physical or virtual medium, although other techniques exist, such as Multi-link PPP, Ethernet VLANs, VxLAN, MPLS, and multi-protocol support over SONET. Virtual circuits An ATM network must establish a connection before two parties can send cells to each other. This is called a virtual circuit (VC). It can be a permanent virtual circuit (PVC), which is created administratively on the end points, or a switched virtual circuit (SVC), which is created as needed by the communicating parties. SVC creation is managed by signaling, in which the requesting party indicates the address of the receiving party, the type of service requested, and whatever traffic parameters may be applicable to the selected service. Call admission is then performed by the network to confirm that the requested resources are available and that a route exists for the connection. Motivation ATM operates as a channel-based transport layer, using VCs. This is encompassed in the concept of the virtual paths (VP) and virtual channels. Every ATM cell has an 8- or 12-bit virtual path identifier (VPI) and 16-bit virtual channel identifier (VCI) pair defined in its header. The VCI, together with the VPI, is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination. The length of the VPI varies according to whether the cell is sent on a user-network interface (at the edge of the network), or if it is sent on a network-network interface (inside the network). As these cells traverse an ATM network, switching takes place by changing the VPI/VCI values (label swapping). Although the VPI/VCI values are not necessarily consistent from one end of the connection to the other, the concept of a circuit is consistent (unlike IP, where any given packet could get to its destination by a different route than the others). ATM switches use the VPI/VCI fields to identify the virtual channel link (VCL) of the next network that a cell needs to transit on its way to its final destination. The function of the VCI is similar to that of the data link connection identifier (DLCI) in Frame Relay and the logical channel number and logical channel group number in X.25. Another advantage of the use of virtual circuits comes with the ability to use them as a multiplexing layer, allowing different services (such as voice, Frame Relay, IP). The VPI is useful for reducing the switching table of some virtual circuits which have common paths. Types ATM can build virtual circuits and virtual paths either statically or dynamically. Static circuits (permanent virtual circuits or PVCs) or paths (permanent virtual paths or PVPs) require that the circuit is composed of a series of segments, one for each pair of interfaces through which it passes. PVPs and PVCs, though conceptually simple, require significant effort in large networks. They also do not support the re-routing of service in the event of a failure. Dynamically built PVPs (soft PVPs or SPVPs) and PVCs (soft PVCs or SPVCs), in contrast, are built by specifying the characteristics of the circuit (the service contract) and the two endpoints. ATM networks create and remove switched virtual circuits (SVCs) on demand when requested by an end station. One application for SVCs is to carry individual telephone calls when a network of telephone switches are interconnected using ATM. SVCs were also used in attempts to replace local area networks with ATM. Routing Most ATM networks supporting SPVPs, SPVCs, and SVCs use the Private Network-to-Network Interface (PNNI) protocol to share topology information between switches and select a route through a network. PNNI is a link-state routing protocol like OSPF and IS-IS. PNNI also includes a very powerful route summarization mechanism to allow construction of very large networks, as well as a call admission control (CAC) algorithm which determines the availability of sufficient bandwidth on a proposed route through a network in order to satisfy the service requirements of a VC or VP. Traffic engineering Another key ATM concept involves the traffic contract. When an ATM circuit is set up each switch on the circuit is informed of the traffic class of the connection. ATM traffic contracts form part of the mechanism by which quality of service (QoS) is ensured. There are four basic types (and several variants) which each have a set of parameters describing the connection. CBR Constant bit rate: a Peak Cell Rate (PCR) is specified, which is constant. VBR Variable bit rate: an average or Sustainable Cell Rate (SCR) is specified, which can peak at a certain level, a PCR, for a maximum interval before being problematic. ABR Available bit rate: a minimum guaranteed rate is specified. UBR Unspecified bit rate: traffic is allocated to all remaining transmission capacity. VBR has real-time and non-real-time variants, and serves for bursty traffic. Non-real-time is sometimes abbreviated to vbr-nrt. Most traffic classes also introduce the concept of cell-delay variation tolerance (CDVT), which defines the clumping of cells in time. Traffic policing To maintain network performance, networks may apply traffic policing to virtual circuits to limit them to their traffic contracts at the entry points to the network, i.e. the user–network interfaces (UNIs) and network-to-network interfaces (NNIs): usage/network parameter control (UPC and NPC). The reference model given by the ITU-T and ATM Forum for UPC and NPC is the generic cell rate algorithm (GCRA), which is a version of the leaky bucket algorithm. CBR traffic will normally be policed to a PCR and CDVt alone, whereas VBR traffic will normally be policed using a dual leaky bucket controller to a PCR and CDVt and an SCR and Maximum Burst Size (MBS). The MBS will normally be the packet (SAR-SDU) size for the VBR VC in cells. If the traffic on a virtual circuit is exceeding its traffic contract, as determined by the GCRA, the network can either drop the cells or mark the Cell Loss Priority (CLP) bit (to identify a cell as potentially redundant). Basic policing works on a cell by cell basis, but this is sub-optimal for encapsulated packet traffic (as discarding a single cell will invalidate the whole packet). As a result, schemes such as partial packet discard (PPD) and early packet discard (EPD) have been created that will discard a whole series of cells until the next packet starts. This reduces the number of useless cells in the network, saving bandwidth for full packets. EPD and PPD work with AAL5 connections as they use the end of packet marker: the ATM user-to-ATM user (AUU) indication bit in the payload-type field of the header, which is set in the last cell of a SAR-SDU. Traffic shaping Traffic shaping usually takes place in the network interface card (NIC) in user equipment, and attempts to ensure that the cell flow on a VC will meet its traffic contract, i.e. cells will not be dropped or reduced in priority at the UNI. Since the reference model given for traffic policing in the network is the GCRA, this algorithm is normally used for shaping as well, and single and dual leaky bucket implementations may be used as appropriate. Reference model The ATM network reference model approximately maps to the three lowest layers of the OSI reference model. It specifies the following layers: At the physical network level, ATM specifies a layer that is equivalent to the OSI physical layer. The ATM layer 2 roughly corresponds to the OSI data link layer. The OSI network layer is implemented as the ATM adaptation layer (AAL). Deployment ATM became popular with telephone companies and many computer makers in the 1990s. However, even by the end of the decade, the better price/performance of Internet Protocol-based products was competing with ATM technology for integrating real-time and bursty network traffic. Companies such as FORE Systems focused on ATM products, while other large vendors such as Cisco Systems provided ATM as an option. After the burst of the dot-com bubble, some still predicted that "ATM is going to dominate". However, in 2005 the ATM Forum, which had been the trade organization promoting the technology, merged with groups promoting other technologies, and eventually became the Broadband Forum. Wireless or mobile ATM Wireless ATM, or mobile ATM, consists of an ATM core network with a wireless access network. ATM cells are transmitted from base stations to mobile terminals. Mobility functions are performed at an ATM switch in the core network, known as "crossover switch", which is similar to the MSC (mobile switching center) of GSM networks. The advantage of wireless ATM is its high bandwidth and high speed handoffs done at layer 2. In the early 1990s, Bell Labs and NEC research labs worked actively in this field. Andy Hopper from the University of Cambridge Computer Laboratory also worked in this area. There was a wireless ATM forum formed to standardize the technology behind wireless ATM networks. The forum was supported by several telecommunication companies, including NEC, Fujitsu and AT&T. Mobile ATM aimed to provide high speed multimedia communications technology, capable of delivering broadband mobile communications beyond that of GSM and WLANs.

The African National Congress (ANC) is a social-democratic political party in South Africa. A liberation movement known for its opposition to apartheid, it has governed the country since 1994, when the first post-apartheid election resulted in Nelson Mandela being elected as President of South Africa. Cyril Ramaphosa, the incumbent national President, has served as President of the ANC since 18 December 2017. Founded on 8 January 1912 in Bloemfontein as the South African Native National Congress, the organisation was formed to agitate for the rights of black South Africans. When the National Party government came to power in 1948, the ANC's central purpose became to oppose the new government's policy of institutionalised apartheid. To this end, its methods and means of organisation shifted; its adoption of the techniques of mass politics, and the swelling of its membership, culminated in the Defiance Campaign of civil disobedience in 1952–53. The ANC was banned by the South African government between April 1960 – shortly after the Sharpeville massacre – and February 1990. During this period, despite periodic attempts to revive its domestic political underground, the ANC was forced into exile by increasing state repression, which saw many of its leaders imprisoned on Robben Island. Headquartered in Lusaka, Zambia, the exiled ANC dedicated much of its attention to a campaign of sabotage and guerrilla warfare against the apartheid state, carried out under its military wing, uMkhonto we Sizwe, which was founded in 1961 in partnership with the South African Communist Party (SACP). The ANC was condemned as a terrorist organisation by the governments of South Africa, the United States, and the United Kingdom. However, it positioned itself as a key player in the negotiations to end apartheid, which began in earnest after the ban was repealed in 1990. In the post-apartheid era, the ANC continues to identify itself foremost as a liberation movement, although it is also a registered political party. Partly due to its Tripartite Alliance with the South African Communist Party (SACP) and the Congress of South African Trade Unions, it has retained a comfortable electoral majority at the national level and in most provinces, and has provided each of South Africa's five presidents since 1994. South Africa is considered a dominant-party state. However, the ANC's electoral majority has declined consistently since 2004, and in the most recent elections – the 2021 local elections – its share of the national vote dropped below 50% for the first time ever. Over the last decade, the party has been embroiled in a number of controversies, particularly relating to widespread allegations of political corruption among its members. History Origins A successor of the Cape Colony's Imbumba Yamanyama organisation, the ANC was founded as the South African Native National Congress in Bloemfontein on 8 January 1912, and was renamed the African National Congress in 1923. Pixley ka Isaka Seme, Sol Plaatje, John Dube, and Walter Rubusana founded the organisation, who, like much of the ANC's early membership, were from the conservative, educated, and religious professional classes of black South African society. Although they would not take part, Xhosa chiefs would show huge support for the organisation. As a result, King Jongilizwe donated 50 cows to during its founding. Around 1920, in a partial shift away from its early focus on the "politics of petitioning", the ANC developed a programme of passive resistance directed primarily at the expansion and entrenchment of pass laws. When Josiah Gumede took over as ANC president in 1927, he advocated for a strategy of mass mobilisation and cooperation with the Communist Party, but was voted out of office in 1930 and replaced with the traditionalist Seme, whose leadership saw the ANC's influence wane. In the 1940s, Alfred Bitini Xuma revived some of Gumede's programmes, assisted by a surge in trade union activity and by the formation in 1944 of the left-wing ANC Youth League under a new generation of activists, among them Walter Sisulu, Nelson Mandela, and Oliver Tambo. After the National Party was elected into government in 1948 on a platform of apartheid, entailing the further institutionalisation of racial segregation, this new generation pushed for a Programme of Action which explicitly advocated African nationalism and led the ANC, for the first time, to the sustained use of mass mobilisation techniques like strikes, stay-aways, and boycotts. This culminated in the 1952–53 Defiance Campaign, a campaign of mass civil disobedience organised by the ANC, the Indian Congress, and the coloured Franchise Action Council in protest of six apartheid laws. The ANC's membership swelled. In June 1955, it was one of the groups represented at the multi-racial Congress of the People in Kliptown, Soweto, which ratified the Freedom Charter, from then onwards a fundamental document in the anti-apartheid struggle. The Charter was the basis of the enduring Congress Alliance, but was also used as a pretext to prosecute hundreds of activists, among them most of the ANC's leadership, in the Treason Trial. Before the trial was concluded, the Sharpeville massacre occurred on 21 March 1960. In the aftermath, the ANC was banned by the South African government. It was not unbanned until February 1990, almost three decades later. Exile in Lusaka After its banning in April 1960, the ANC was driven underground, a process hastened by a barrage of government banning orders, by an escalation of state repression, and by the imprisonment of senior ANC leaders pursuant to the Rivonia trial and Little Rivonia trial. From around 1963, the ANC effectively abandoned much of even its underground presence inside South Africa and operated almost entirely from its external mission, with headquarters first in Morogoro, Tanzania, and later in Lusaka, Zambia. For the entirety of its time in exile, the ANC was led by Tambo – first de facto, with president Albert Luthuli under house arrest in Zululand; then in an acting capacity, after Luthuli's death in 1967; and, finally, officially, after a leadership vote in 1985. Also notable about this period was the extremely close relationship between the ANC and the reconstituted South African Communist Party (SACP), which was also in exile. uMkhonto we Sizwe In 1961, partly in response to the Sharpeville massacre, leaders of the SACP and the ANC formed a military body, Umkhonto we Sizwe (MK, Spear of the Nation), as a vehicle for armed struggle against the apartheid state. Initially, MK was not an official ANC body, nor had it been directly established by the ANC National Executive: it was considered an autonomous organisation, until such time as the ANC formally recognised it as its armed wing in October 1962. In the first half of the 1960s, MK was preoccupied with a campaign of sabotage attacks, especially bombings of unoccupied government installations. As the ANC reduced its presence inside South Africa, however, MK cadres were increasingly confined to training camps in Tanzania and neighbouring countries – with such exceptions as the Wankie Campaign, a momentous military failure. In 1969, Tambo was compelled to call the landmark Morogoro Conference to address the grievances of the rank-and-file, articulated by Chris Hani in a memorandum which depicted MK's leadership as corrupt and complacent. Although MK's malaise persisted into the 1970s, conditions for armed struggle soon improved considerably, especially after the Soweto uprising of 1976 in South Africa saw thousands of students – inspired by Black Consciousness ideas – cross the borders to seek military training. MK guerrilla activity inside South Africa increased steadily over this period, with one estimate recording an increase from 23 incidents in 1977 to 136 incidents in 1985. In the latter half of the 1980s, a number of South African civilians were killed in these attacks, a reversal of the ANC's earlier reluctance to incur civilian casualties. Fatal attacks included the 1983 Church Street bombing, the 1985 Amanzimtoti bombing, the 1986 Magoo's Bar bombing, and the 1987 Johannesburg Magistrate's Court bombing. Partly in retaliation, the South African Defence Force increasingly crossed the border to target ANC members and ANC bases, as in the 1981 raid on Maputo, 1983 raid on Maputo, and 1985 raid on Gaborone. During this period, MK activities led the governments of Margaret Thatcher and Ronald Reagan to condemn the ANC as a terrorist organisation. In fact, neither the ANC nor Mandela were removed from the U.S. terror watch list until 2008. The animosity of Western regimes was partly explained by the Cold War context, and by the considerable amount of support – both financial and technical – that the ANC received from the Soviet Union. Negotiations to end apartheid From the mid-1980s, as international and internal opposition to apartheid mounted, elements of the ANC began to test the prospects for a negotiated settlement with the South African government, although the prudence of abandoning armed struggle was an extremely controversial topic within the organisation. Following preliminary contact between the ANC and representatives of the state, business, and civil society, President F. W. de Klerk announced in February 1990 that the government would unban the ANC and other banned political organisations, and that Mandela would be released from prison. Some ANC leaders returned to South Africa from exile for so-called "talks about talks", which led in 1990 and 1991 to a series of bilateral accords with the government establishing a mutual commitment to negotiations. Importantly, the Pretoria Minute of August 1990 included a commitment by the ANC to unilaterally suspend its armed struggle. This made possible the multi-party Convention for a Democratic South Africa and later the Multi-Party Negotiating Forum, in which the ANC was regarded as the main representative of the interests of the anti-apartheid movement. However, ongoing political violence, which the ANC attributed to a state-sponsored third force, led to recurrent tensions. Most dramatically, after the Boipatong massacre of June 1992, the ANC announced that it was withdrawing from negotiations indefinitely. It faced further casualties in the Bisho massacre, the Shell House massacre, and in other clashes with state forces and supporters of the Inkatha Freedom Party (IFP). However, once negotiations resumed, they resulted in November 1993 in an interim Constitution, which governed South Africa's first democratic elections on 27 April 1994. In the elections, the ANC won an overwhelming 62.65% majority of the vote. Mandela was elected president and formed a coalition Government of National Unity, which, under the provisions of the interim Constitution, also included the National Party and IFP. The ANC has controlled the national government since then. Breakaways In the post-apartheid era, two significant breakaway groups have been formed by former ANC members. The first is the Congress of the People, founded by Mosiuoa Lekota in 2008 in the aftermath of the Polokwane elective conference, when the ANC declined to re-elect Thabo Mbeki as its president and instead compelled his resignation from the national presidency. The second breakaway is the Economic Freedom Fighters, founded in 2013 after youth leader Julius Malema was expelled from the ANC. Before these, the most important split in the ANC's history occurred in 1959, when Robert Sobukwe led a splinter faction of African nationalists to the new Pan Africanist Congress. Current structure and composition Leadership Under the ANC constitution, every member of the ANC belongs to a local branch, and branch members select the organisation's policies and leaders. They do so primarily by electing delegates to the National Conference, which is currently convened every five years. Between conferences, the organisation is led by its 86-member National Executive Committee, which is elected at each conference. The most senior members of the National Executive Committee are the so-called Top Six officials, the ANC president primary among them. A symmetrical process occurs at the subnational levels: each of the nine provincial executive committees and regional executive committees are elected at provincial and regional elective conferences respectively, also attended by branch delegates; and branch officials are elected at branch general meetings. Leagues The ANC has three leagues: the Women's League, the Youth League and the Veterans' League. Under the ANC constitution, the leagues are autonomous bodies with the scope to devise their own constitutions and policies; for the purpose of national conferences, they are treated somewhat like provinces, with voting delegates and the power to nominate leadership candidates. Tripartite Alliance The ANC is recognised as the leader of a three-way alliance, known as the Tripartite Alliance, with the SACP and Congress of South African Trade Unions (COSATU). The alliance was formalised in mid-1990, after the ANC was unbanned, but has deeper historical roots: the SACP had worked closely with the ANC in exile, and COSATU had aligned itself with the Freedom Charter and Congress Alliance in 1987. The membership and leadership of the three organisations has traditionally overlapped significantly. The alliance constitutes a de facto electoral coalition: the SACP and COSATU do not contest in government elections, but field candidates through the ANC, hold senior positions in the ANC, and influence party policy. However, the SACP, in particular, has frequently threatened to field its own candidates, and in 2017 it did so for the first time, running against the ANC in by-elections in the Metsimaholo municipality, Free State. Electoral candidates Under South Africa's closed-list proportional representation electoral system, parties have immense power in selecting candidates for legislative bodies. The ANC's internal candidate selection process is overseen by so-called list committees and tends to involve a degree of broad democratic participation, especially at the local level, where ANC branches vote to nominate candidates for the local government elections. Between 2003 and 2008, the ANC also gained a significant number of members through the controversial floor crossing process, which occurred especially at the local level. The leaders of the executive in each sphere of government – the president, the provincial premiers, and the mayors – are indirectly elected after each election. In practice, the selection of ANC candidates for these positions is highly centralised, with the ANC caucus voting together to elect a pre-decided candidate. Although the ANC does not always announce whom its caucuses intend to elect, the National Assembly has thus far always elected the ANC president as the national president. Cadre deployment The ANC has adhered to a formal policy of cadre deployment since 1985. In the post-apartheid era, the policy includes but is not exhausted by selection of candidates for elections and government positions: it also entails that the central organisation "deploys" ANC members to various other strategic positions in the party, state, and economy. Ideology and policies The ANC prides itself on being a broad church, and, like many dominant parties, resembles a catch-all party, accommodating a range of ideological tendencies. As Mandela told the Washington Post in 1990:The ANC has never been a political party. It was formed as a parliament of the African people. Right from the start, up to now, the ANC is a coalition, if you want, of people of various political affiliations. Some will support free enterprise, others socialism. Some are conservatives, others are liberals. We are united solely by our determination to oppose racial oppression. That is the only thing that unites us. There is no question of ideology as far as the odyssey of the ANC is concerned, because any question approaching ideology would split the organization from top to bottom. Because we have no connection whatsoever except at this one, of our determination to dismantle apartheid. The post-apartheid ANC continues to identify itself foremost as a liberation movement, pursuing "the complete liberation of the country from all forms of discrimination and national oppression". It also continues to claim the Freedom Charter of 1955 as "the basic policy document of the ANC". However, as NEC member Jeremy Cronin noted in 2007, the various broad principles of the Freedom Charter have been given different interpretations, and emphasised to differing extents, by different groups within the organisation. Nonetheless, some basic commonalities are visible in the policy and ideological preferences of the organisation's mainstream. Non-racialism The ANC is committed to the ideal of non-racialism and to opposing "any form of racial, tribalistic or ethnic exclusivism or chauvinism". National Democratic Revolution The 1969 Morogoro Conference committed the ANC to a "national democratic revolution [which] – destroying the existing social and economic relationship – will bring with it a correction of the historical injustices perpetrated against the indigenous majority and thus lay the basis for a new – and deeper internationalist – approach". For the movement's intellectuals, the concept of the National Democratic Revolution (NDR) was a means of reconciling the anti-apartheid and anti-colonial project with a second goal, that of establishing domestic and international socialism – the ANC is a member of the Socialist International, and its close partner the SACP traditionally conceives itself as a vanguard party. Specifically, and as implied by the 1969 document, NDR doctrine entails that the transformation of the domestic political system (national struggle, in Joe Slovo's phrase) is a precondition for a socialist revolution (class struggle). The concept remained important to ANC intellectuals and strategists after the end of apartheid. Indeed, the pursuit of the NDR is one of the primary objectives of the ANC as set out in its constitution. As with the Freedom Charter, the ambiguity of the NDR has allowed it to bear varying interpretations. For example, whereas SACP theorists tend to emphasise the anti-capitalist character of the NDR, some ANC policymakers have construed it as implying the empowerment of the black majority even within a market-capitalist scheme. Economic interventionism Since 1994, consecutive ANC governments have held a strong preference for a significant degree of state intervention in the economy. The ANC's first comprehensive articulation of its post-apartheid economic policy framework was set out in the Reconstruction and Development Programme (RDP) document of 1994, which became its electoral manifesto and also, under the same name, the flagship policy of Nelson Mandela's government. The RDP aimed both to redress the socioeconomic inequalities created by colonialism and apartheid, and to promote economic growth and development; state intervention was judged a necessary step towards both goals. Specifically, the state was to intervene in the economy through three primary channels: a land reform programme; a degree of economic planning, through industrial and trade policy; and state investments in infrastructure and the provision of basic services, including health and education. Although the RDP was abandoned in 1996, these three channels of state economic intervention have remained mainstays of subsequent ANC policy frameworks. Neoliberal turn In 1996, Mandela's government replaced the RDP with the Growth Employment and Redistribution (GEAR) programme, which was maintained under President Thabo Mbeki, Mandela's successor. GEAR has been characterised as a neoliberal policy, and it was disowned by both COSATU and the SACP. While some analysts viewed Mbeki's economic policy as undertaking the uncomfortable macroeconomic adjustments necessary for long-term growth, others – notably Patrick Bond – viewed it as a reflection of the ANC's failure to implement genuinely radical transformation after 1994. Debate about ANC commitment to redistribution on a socialist scale has continued: in 2013, the country's largest trade union, the National Union of Metalworkers of South Africa, withdrew its support for the ANC on the basis that "the working class cannot any longer see the ANC or the SACP as its class allies in any meaningful sense". It is evident, however, that the ANC never embraced free-market capitalism, and continued to favour a mixed economy: even as the debate over GEAR raged, the ANC declared itself (in 2004) a social-democratic party, and it was at that time presiding over phenomenal expansions of its black economic empowerment programme and the system of social grants. Developmental state As its name suggests, the RDP emphasised state-led development – that is, a developmental state – which the ANC has typically been cautious, at least in its rhetoric, to distinguish from the neighbouring concept of a welfare state. In the mid-2000s, during Mbeki's second term, the notion of a developmental state was revived in South African political discourse when the national economy worsened; and the 2007 National Conference whole-heartedly endorsed developmentalism in its policy resolutions, calling for a state "at the centre of a mixed economy... which leads and guides that economy and which intervenes in the interest of the people as a whole". The proposed developmental state was also central to the ANC's campaign in the 2009 elections, and it remains a central pillar of the policy of the current government, which seeks to build a "capable and developmental" state. In this regard, ANC politicians often cite China as an aspirational example. A discussion document ahead of the ANC's 2015 National General Council proposed that:China['s] economic development trajectory remains a leading example of the triumph of humanity over adversity. The exemplary role of the collective leadership of the Communist Party of China in this regard should be a guiding lodestar of our own struggle. Radical economic transformation Towards the end of Jacob Zuma's presidency, an ANC faction aligned to Zuma pioneered a new policy platform referred to as radical economic transformation (RET). Zuma announced the new focus on RET during his February 2017 State of the Nation address, and later that year, explaining that it had been adopted as ANC policy and therefore as government policy, defined it as entailing "fundamental change in the structures, systems, institutions and patterns of ownership and control of the economy, in favour of all South Africans, especially the poor". Arguments for RET were closely associated with the rhetorical concept of white monopoly capital. At the 54th National Conference in 2017, the ANC endorsed a number of policy principles advocated by RET supporters, including their proposal to pursue land expropriation without compensation as a matter of national policy. Foreign policy and relations The ANC has long had close ties with China and the Chinese Communist Party (CCP), with the CCP having supported ANC's struggle of apartheid since 1961. In 2008, the two parties signed a memorandum of understanding to train ANC members in China. President Cyril Ramaphosa and the ANC have not condemned the Russian invasion of Ukraine, and have faced criticism from opposition parties, public commentators, academics, civil society organisations, and former ANC members due to this. The ANC youth wing has meanwhile condemned sanctions against Russia and denounced NATO's eastward expansion as "fascistic". Officials representing the ANC Youth League acted as international observers for Russia's staged referendum to annex Ukrainian territory conquered during the war. Symbols and media Flag and logo The logo of the ANC incorporates a spear and shield – symbolising the historical and ongoing struggle, armed and otherwise, against colonialism and racial oppression – and a wheel, which is borrowed from the 1955 Congress of the People campaign and therefore symbolises a united and non-racial movement for freedom and equality. The logo uses the same colours as the ANC flag, which comprises three horizontal stripes of equal width in black, green and gold. The black symbolises the native people of South Africa; the green represents the land of South Africa; and the gold represents the country's mineral and other natural wealth. The black, green and gold tricolour also appeared on the flag of the KwaZulu bantustan and appears on the flag of the ANC's rival, the IFP; and all three colours appear in the post-apartheid South African national flag. Publications Since 1996, the ANC Department of Political Education has published the quarterly Umrabulo political discussion journal; and ANC Today, a weekly online newsletter, was launched in 2001 to offset the alleged bias of the press. In addition, since 1972, it has been traditional for the ANC president to publish annually a so-called January 8 Statement: a reflective letter sent to members on 8 January, the anniversary of the organisation's founding. In earlier years, the ANC published a range of periodicals, the most important of which was the monthly journal Sechaba (1967–1990), printed in the German Democratic Republic and banned by the apartheid government. The ANC's Radio Freedom also gained a wide audience during apartheid. Amandla "Amandla ngawethu", or the Sotho variant "Matla ke arona", is a common rallying call at ANC meetings, roughly meaning "power to the people". It is also common for meetings to sing so-called struggle songs, which were sung during anti-apartheid meetings and in MK camps. In the case of at least two of these songs – Dubula ibhunu and Umshini wami – this has caused controversy in recent years. Criticism and controversy Corruption controversies The most prominent corruption case involving the ANC relates to a series of bribes paid to companies involved in the ongoing R55 billion Arms Deal saga, which resulted in a long term jail sentence to then Deputy President Jacob Zuma's legal adviser Schabir Shaik. Zuma, the former South African President, was charged with fraud, bribery and corruption in the Arms Deal, but the charges were subsequently withdrawn by the National Prosecuting Authority of South Africa due to their delay in prosecution. The ANC has also been criticised for its subsequent abolition of the Scorpions, the multidisciplinary agency that investigated and prosecuted organised crime and corruption, and was heavily involved in the investigation into Zuma and Shaik. Tony Yengeni, in his position as chief whip of the ANC and head of the Parliaments defence committee has recently been named as being involved in bribing the German company ThyssenKrupp over the purchase of four corvettes for the SANDF. Other recent corruption issues include the sexual misconduct and criminal charges of Beaufort West municipal manager Truman Prince, and the Oilgate scandal, in which millions of Rand in funds from a state-owned company were funnelled into ANC coffers. The ANC has also been accused of using government and civil society to fight its political battles against opposition parties such as the Democratic Alliance. The result has been a number of complaints and allegations that none of the political parties truly represent the interests of the poor. This has resulted in the "No Land! No House! No Vote!" Campaign which became very prominent during elections. In 2018, the New York Times reported on the killings of ANC corruption whistleblowers. During an address on 28 October 2021, former president Thabo Mbeki commented on the history of corruption within the ANC. He reflected that Mandela had already warned in 1997 that the ANC was attracting individuals who viewed the party as "a route to power and self-enrichment." He added that the ANC leadership "did not know how to deal with this problem." During a lecture on 10 December, Mbeki reiterated concerns about "careerists" within the party, and stressed the need to "purge itself of such members". Condemnation over Secrecy Bill In late 2011 the ANC was heavily criticised over the passage of the Protection of State Information Bill, which opponents claimed would improperly restrict the freedom of the press. Opposition to the bill included otherwise ANC-aligned groups such as COSATU. Notably, Nelson Mandela and other Nobel laureates Nadine Gordimer, Archbishop Desmond Tutu, and F. W. de Klerk have expressed disappointment with the bill for not meeting standards of constitutionality and aspirations for freedom of information and expression. Role in the Marikana killings The ANC have been criticised for its role in failing to prevent 16 August 2012 massacre of Lonmin miners at Marikana in the Northwest. Some allege that Police Commissioner Riah Phiyega and Police Minister Nathi Mthethwa may have given the go ahead for the police action against the miners on that day. Commissioner Phiyega of the ANC came under further criticism as being insensitive and uncaring when she was caught smiling and laughing during the Farlam Commission's video playback of the 'massacre'. Archbishop Desmond Tutu has announced that he no longer can bring himself to exercise a vote for the ANC as it is no longer the party that he and Nelson Mandela fought for, and that the party has now lost its way, and is in danger of becoming a corrupt entity in power. Financial mismanagement Since at least 2017, the ANC has encountered significant problems related to financial mismanagement. According to a report filed by the former treasurer-general Zweli Mkhize in December 2017, the ANC was technically insolvent as its liabilities exceeded its assets. These problems continued into the second half of 2021. By September 2021, the ANC had reportedly amassed a debt exceeding R200-million, including over R100-million owed to the South African Revenue Service. Beginning in May 2021, the ANC failed to pay monthly staff salaries on time. Having gone without pay for three consecutive months, workers planned a strike in late August 2021. In response, the ANC initiated a crowdfunding campaign to raise money for staff salaries. By November 2021, its Cape Town staff was approaching their fourth month without salaries, while medical aid and provident fund contributions had been suspended in various provinces. The party has countered that the Political Party Funding Act, which prohibits anonymous contributions, has dissuaded some donors who previously injected money for salaries. State capture In January 2018, then-President Jacob Zuma established the Zondo Commission to investigate allegations of state capture, corruption, and fraud in the public sector. Over the following four years, the Commission heard testimony from over 250 witnesses and collected more than 150,000 pages of evidence. After several extensions, the first part of the final three-part report was published on 4 January 2022. The report found that the ANC, including Zuma and his political allies, had benefited from the extensive corruption of state enterprises, including the South African Revenue Service. It also found that the ANC "simply did not care that state entities were in decline during state capture or they slept on the job – or they simply didn't know what to do."

Amphetamine (contracted from alpha-methylphenethylamine) is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity. Amphetamine was discovered as a chemical in 1887 by Lazăr Edeleanu, and then as a drug in the late 1920s. It exists as two enantiomers: levoamphetamine and dextroamphetamine. Amphetamine properly refers to a specific chemical, the racemic free base, which is equal parts of the two enantiomers in their pure amine forms. The term is frequently used informally to refer to any combination of the enantiomers, or to either of them alone. Historically, it has been used to treat nasal congestion and depression. Amphetamine is also used as an athletic performance enhancer and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant. It is a prescription drug in many countries, and unauthorized possession and distribution of amphetamine are often tightly controlled due to the significant health risks associated with recreational use. The first amphetamine pharmaceutical was Benzedrine, a brand which was used to treat a variety of conditions. Currently, pharmaceutical amphetamine is prescribed as racemic amphetamine, Adderall, dextroamphetamine, or the inactive prodrug lisdexamfetamine. Amphetamine increases monoamine and excitatory neurotransmission in the brain, with its most pronounced effects targeting the norepinephrine and dopamine neurotransmitter systems. At therapeutic doses, amphetamine causes emotional and cognitive effects such as euphoria, change in desire for sex, increased wakefulness, and improved cognitive control. It induces physical effects such as improved reaction time, fatigue resistance, and increased muscle strength. Larger doses of amphetamine may impair cognitive function and induce rapid muscle breakdown. Addiction is a serious risk with heavy recreational amphetamine use, but is unlikely to occur from long-term medical use at therapeutic doses. Very high doses can result in psychosis (e.g., delusions and paranoia) which rarely occurs at therapeutic doses even during long-term use. Recreational doses are generally much larger than prescribed therapeutic doses and carry a far greater risk of serious side effects. Amphetamine belongs to the phenethylamine class. It is also the parent compound of its own structural class, the substituted amphetamines, which includes prominent substances such as bupropion, cathinone, MDMA, and methamphetamine. As a member of the phenethylamine class, amphetamine is also chemically related to the naturally occurring trace amine neuromodulators, specifically phenethylamine and , both of which are produced within the human body. Phenethylamine is the parent compound of amphetamine, while is a positional isomer of amphetamine that differs only in the placement of the methyl group. Uses Medical Amphetamine is used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy (a sleep disorder), and obesity, and is sometimes prescribed for its past medical indications, particularly for depression and chronic pain. Long-term amphetamine exposure at sufficiently high doses in some animal species is known to produce abnormal dopamine system development or nerve damage, but, in humans with ADHD, long-term use of pharmaceutical amphetamines at therapeutic doses appears to improve brain development and nerve growth. Reviews of magnetic resonance imaging (MRI) studies suggest that long-term treatment with amphetamine decreases abnormalities in brain structure and function found in subjects with ADHD, and improves function in several parts of the brain, such as the right caudate nucleus of the basal ganglia. Reviews of clinical stimulant research have established the safety and effectiveness of long-term continuous amphetamine use for the treatment of ADHD. Randomized controlled trials of continuous stimulant therapy for the treatment of ADHD spanning 2 years have demonstrated treatment effectiveness and safety. Two reviews have indicated that long-term continuous stimulant therapy for ADHD is effective for reducing the core symptoms of ADHD (i.e., hyperactivity, inattention, and impulsivity), enhancing quality of life and academic achievement, and producing improvements in a large number of functional outcomes across 9 categories of outcomes related to academics, antisocial behavior, driving, non-medicinal drug use, obesity, occupation, self-esteem, service use (i.e., academic, occupational, health, financial, and legal services), and social function. One review highlighted a nine-month randomized controlled trial of amphetamine treatment for ADHD in children that found an average increase of 4.5 IQ points, continued increases in attention, and continued decreases in disruptive behaviors and hyperactivity. Another review indicated that, based upon the longest follow-up studies conducted to date, lifetime stimulant therapy that begins during childhood is continuously effective for controlling ADHD symptoms and reduces the risk of developing a substance use disorder as an adult. Current models of ADHD suggest that it is associated with functional impairments in some of the brain's neurotransmitter systems; these functional impairments involve impaired dopamine neurotransmission in the mesocorticolimbic projection and norepinephrine neurotransmission in the noradrenergic projections from the locus coeruleus to the prefrontal cortex. Psychostimulants like methylphenidate and amphetamine are effective in treating ADHD because they increase neurotransmitter activity in these systems. Approximately 80% of those who use these stimulants see improvements in ADHD symptoms. Children with ADHD who use stimulant medications generally have better relationships with peers and family members, perform better in school, are less distractible and impulsive, and have longer attention spans. The Cochrane reviews on the treatment of ADHD in children, adolescents, and adults with pharmaceutical amphetamines stated that short-term studies have demonstrated that these drugs decrease the severity of symptoms, but they have higher discontinuation rates than non-stimulant medications due to their adverse side effects. A Cochrane review on the treatment of ADHD in children with tic disorders such as Tourette syndrome indicated that stimulants in general do not make tics worse, but high doses of dextroamphetamine could exacerbate tics in some individuals. Enhancing performance Cognitive performance In 2015, a systematic review and a meta-analysis of high quality clinical trials found that, when used at low (therapeutic) doses, amphetamine produces modest yet unambiguous improvements in cognition, including working memory, long-term episodic memory, inhibitory control, and some aspects of attention, in normal healthy adults; these cognition-enhancing effects of amphetamine are known to be partially mediated through the indirect activation of both dopamine receptor D1 and adrenoceptor α2 in the prefrontal cortex. A systematic review from 2014 found that low doses of amphetamine also improve memory consolidation, in turn leading to improved recall of information. Therapeutic doses of amphetamine also enhance cortical network efficiency, an effect which mediates improvements in working memory in all individuals. Amphetamine and other ADHD stimulants also improve task saliency (motivation to perform a task) and increase arousal (wakefulness), in turn promoting goal-directed behavior. Stimulants such as amphetamine can improve performance on difficult and boring tasks and are used by some students as a study and test-taking aid. Based upon studies of self-reported illicit stimulant use, of college students use diverted ADHD stimulants, which are primarily used for enhancement of academic performance rather than as recreational drugs. However, high amphetamine doses that are above the therapeutic range can interfere with working memory and other aspects of cognitive control. Physical performance Amphetamine is used by some athletes for its psychological and athletic performance-enhancing effects, such as increased endurance and alertness; however, non-medical amphetamine use is prohibited at sporting events that are regulated by collegiate, national, and international anti-doping agencies. In healthy people at oral therapeutic doses, amphetamine has been shown to increase muscle strength, acceleration, athletic performance in anaerobic conditions, and endurance (i.e., it delays the onset of fatigue), while improving reaction time. Amphetamine improves endurance and reaction time primarily through reuptake inhibition and release of dopamine in the central nervous system. Amphetamine and other dopaminergic drugs also increase power output at fixed levels of perceived exertion by overriding a "safety switch", allowing the core temperature limit to increase in order to access a reserve capacity that is normally off-limits. At therapeutic doses, the adverse effects of amphetamine do not impede athletic performance; however, at much higher doses, amphetamine can induce effects that severely impair performance, such as rapid muscle breakdown and elevated body temperature. Recreational Amphetamine, specifically the more dopaminergic dextrorotatory enantiomer (dextroamphetamine), is also used recreationally as a euphoriant and aphrodisiac, and like other amphetamines; is used as a club drug for its energetic and euphoric high. Dextroamphetamine (d-amphetamine) is considered to have a high potential for misuse in a recreational manner since individuals typically report feeling euphoric, more alert, and more energetic after taking the drug. A notable part of the 1960s mod subculture in the UK was recreational amphetamine use, which was used to fuel all-night dances at clubs like Manchester's Twisted Wheel. Newspaper reports described dancers emerging from clubs at 5 a.m. with dilated pupils. Mods used the drug for stimulation and alertness, which they viewed as different from the intoxication caused by alcohol and other drugs. Dr. Andrew Wilson argues that for a significant minority, "amphetamines symbolised the smart, on-the-ball, cool image" and that they sought "stimulation not intoxication [...] greater awareness, not escape" and "confidence and articulacy" rather than the "drunken rowdiness of previous generations." Dextroamphetamine's dopaminergic (rewarding) properties affect the mesocorticolimbic circuit; a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), positive reinforcement and positively-valenced emotions, particularly ones involving pleasure. Large recreational doses of dextroamphetamine may produce symptoms of dextroamphetamine overdose. Recreational users sometimes open dexedrine capsules and crush the contents in order to insufflate (snort) it or subsequently dissolve it in water and inject it. Immediate-release formulations have higher potential for abuse via insufflation (snorting) or intravenous injection due to a more favorable pharmacokinetic profile and easy crushability (especially tablets). Injection into the bloodstream can be dangerous because insoluble fillers within the tablets can block small blood vessels. Chronic overuse of dextroamphetamine can lead to severe drug dependence, resulting in withdrawal symptoms when drug use stops. Contraindications According to the International Programme on Chemical Safety (IPCS) and the United States Food and Drug Administration (USFDA), amphetamine is contraindicated in people with a history of drug abuse, cardiovascular disease, severe agitation, or severe anxiety. It is also contraindicated in individuals with advanced arteriosclerosis (hardening of the arteries), glaucoma (increased eye pressure), hyperthyroidism (excessive production of thyroid hormone), or moderate to severe hypertension. These agencies indicate that people who have experienced allergic reactions to other stimulants or who are taking monoamine oxidase inhibitors (MAOIs) should not take amphetamine, although safe concurrent use of amphetamine and monoamine oxidase inhibitors has been documented. These agencies also state that anyone with anorexia nervosa, bipolar disorder, depression, hypertension, liver or kidney problems, mania, psychosis, Raynaud's phenomenon, seizures, thyroid problems, tics, or Tourette syndrome should monitor their symptoms while taking amphetamine. Evidence from human studies indicates that therapeutic amphetamine use does not cause developmental abnormalities in the fetus or newborns (i.e., it is not a human teratogen), but amphetamine abuse does pose risks to the fetus. Amphetamine has also been shown to pass into breast milk, so the IPCS and the USFDA advise mothers to avoid breastfeeding when using it. Due to the potential for reversible growth impairments, the USFDA advises monitoring the height and weight of children and adolescents prescribed an amphetamine pharmaceutical. Adverse effects The adverse side effects of amphetamine are many and varied, and the amount of amphetamine used is the primary factor in determining the likelihood and severity of adverse effects. Amphetamine products such as Adderall, Dexedrine, and their generic equivalents are currently approved by the USFDA for long-term therapeutic use. Recreational use of amphetamine generally involves much larger doses, which have a greater risk of serious adverse drug effects than dosages used for therapeutic purposes. Physical Cardiovascular side effects can include hypertension or hypotension from a vasovagal response, Raynaud's phenomenon (reduced blood flow to the hands and feet), and tachycardia (increased heart rate). Sexual side effects in males may include erectile dysfunction, frequent erections, or prolonged erections. Gastrointestinal side effects may include abdominal pain, constipation, diarrhea, and nausea. Other potential physical side effects include appetite loss, blurred vision, dry mouth, excessive grinding of the teeth, nosebleed, profuse sweating, rhinitis medicamentosa (drug-induced nasal congestion), reduced seizure threshold, tics (a type of movement disorder), and weight loss. Dangerous physical side effects are rare at typical pharmaceutical doses. Amphetamine stimulates the medullary respiratory centers, producing faster and deeper breaths. In a normal person at therapeutic doses, this effect is usually not noticeable, but when respiration is already compromised, it may be evident. Amphetamine also induces contraction in the urinary bladder sphincter, the muscle which controls urination, which can result in difficulty urinating. This effect can be useful in treating bed wetting and loss of bladder control. The effects of amphetamine on the gastrointestinal tract are unpredictable. If intestinal activity is high, amphetamine may reduce gastrointestinal motility (the rate at which content moves through the digestive system); however, amphetamine may increase motility when the smooth muscle of the tract is relaxed. Amphetamine also has a slight analgesic effect and can enhance the pain relieving effects of opioids. USFDA-commissioned studies from 2011 indicate that in children, young adults, and adults there is no association between serious adverse cardiovascular events (sudden death, heart attack, and stroke) and the medical use of amphetamine or other ADHD stimulants. However, amphetamine pharmaceuticals are contraindicated in individuals with cardiovascular disease. Psychological At normal therapeutic doses, the most common psychological side effects of amphetamine include increased alertness, apprehension, concentration, initiative, self-confidence and sociability, mood swings (elated mood followed by mildly depressed mood), insomnia or wakefulness, and decreased sense of fatigue. Less common side effects include anxiety, change in libido, grandiosity, irritability, repetitive or obsessive behaviors, and restlessness; these effects depend on the user's personality and current mental state. Amphetamine psychosis (e.g., delusions and paranoia) can occur in heavy users. Although very rare, this psychosis can also occur at therapeutic doses during long-term therapy. According to the USFDA, "there is no systematic evidence" that stimulants produce aggressive behavior or hostility. Amphetamine has also been shown to produce a conditioned place preference in humans taking therapeutic doses, meaning that individuals acquire a preference for spending time in places where they have previously used amphetamine. Reinforcement disorders Addiction Addiction is a serious risk with heavy recreational amphetamine use, but is unlikely to occur from long-term medical use at therapeutic doses; in fact, lifetime stimulant therapy for ADHD that begins during childhood reduces the risk of developing substance use disorders as an adult. Pathological overactivation of the mesolimbic pathway, a dopamine pathway that connects the ventral tegmental area to the nucleus accumbens, plays a central role in amphetamine addiction. Individuals who frequently self-administer high doses of amphetamine have a high risk of developing an amphetamine addiction, since chronic use at high doses gradually increases the level of accumbal ΔFosB, a "molecular switch" and "master control protein" for addiction. Once nucleus accumbens ΔFosB is sufficiently overexpressed, it begins to increase the severity of addictive behavior (i.e., compulsive drug-seeking) with further increases in its expression. While there are currently no effective drugs for treating amphetamine addiction, regularly engaging in sustained aerobic exercise appears to reduce the risk of developing such an addiction. Exercise therapy improves clinical treatment outcomes and may be used as an adjunct therapy with behavioral therapies for addiction. Biomolecular mechanisms Chronic use of amphetamine at excessive doses causes alterations in gene expression in the mesocorticolimbic projection, which arise through transcriptional and epigenetic mechanisms. The most important transcription factors that produce these alterations are Delta FBJ murine osteosarcoma viral oncogene homolog B (ΔFosB), cAMP response element binding protein (CREB), and nuclear factor-kappa B (NF-κB). ΔFosB is the most significant biomolecular mechanism in addiction because ΔFosB overexpression (i.e., an abnormally high level of gene expression which produces a pronounced gene-related phenotype) in the D1-type medium spiny neurons in the nucleus accumbens is necessary and sufficient for many of the neural adaptations and regulates multiple behavioral effects (e.g., reward sensitization and escalating drug self-administration) involved in addiction. Once ΔFosB is sufficiently overexpressed, it induces an addictive state that becomes increasingly more severe with further increases in ΔFosB expression. It has been implicated in addictions to alcohol, cannabinoids, cocaine, methylphenidate, nicotine, opioids, phencyclidine, propofol, and substituted amphetamines, among others. ΔJunD, a transcription factor, and G9a, a histone methyltransferase enzyme, both oppose the function of ΔFosB and inhibit increases in its expression. Sufficiently overexpressing ΔJunD in the nucleus accumbens with viral vectors can completely block many of the neural and behavioral alterations seen in chronic drug abuse (i.e., the alterations mediated by ΔFosB). Similarly, accumbal G9a hyperexpression results in markedly increased histone 3 lysine residue 9 dimethylation (H3K9me2) and blocks the induction of ΔFosB-mediated neural and behavioral plasticity by chronic drug use, which occurs via H3K9me2-mediated repression of transcription factors for ΔFosB and H3K9me2-mediated repression of various ΔFosB transcriptional targets (e.g., CDK5). ΔFosB also plays an important role in regulating behavioral responses to natural rewards, such as palatable food, sex, and exercise. Since both natural rewards and addictive drugs induce the expression of ΔFosB (i.e., they cause the brain to produce more of it), chronic acquisition of these rewards can result in a similar pathological state of addiction. Consequently, ΔFosB is the most significant factor involved in both amphetamine addiction and amphetamine-induced sexual addictions, which are compulsive sexual behaviors that result from excessive sexual activity and amphetamine use. These sexual addictions are associated with a dopamine dysregulation syndrome which occurs in some patients taking dopaminergic drugs. The effects of amphetamine on gene regulation are both dose- and route-dependent. Most of the research on gene regulation and addiction is based upon animal studies with intravenous amphetamine administration at very high doses. The few studies that have used equivalent (weight-adjusted) human therapeutic doses and oral administration show that these changes, if they occur, are relatively minor. This suggests that medical use of amphetamine does not significantly affect gene regulation. Pharmacological treatments there is no effective pharmacotherapy for amphetamine addiction. Reviews from 2015 and 2016 indicated that TAAR1-selective agonists have significant therapeutic potential as a treatment for psychostimulant addictions; however, the only compounds which are known to function as TAAR1-selective agonists are experimental drugs. Amphetamine addiction is largely mediated through increased activation of dopamine receptors and NMDA receptors in the nucleus accumbens; magnesium ions inhibit NMDA receptors by blocking the receptor calcium channel. One review suggested that, based upon animal testing, pathological (addiction-inducing) psychostimulant use significantly reduces the level of intracellular magnesium throughout the brain. Supplemental magnesium treatment has been shown to reduce amphetamine self-administration (i.e., doses given to oneself) in humans, but it is not an effective monotherapy for amphetamine addiction. A systematic review and meta-analysis from 2019 assessed the efficacy of 17 different pharmacotherapies used in randomized controlled trials (RCTs) for amphetamine and methamphetamine addiction; it found only low-strength evidence that methylphenidate might reduce amphetamine or methamphetamine self-administration. There was low- to moderate-strength evidence of no benefit for most of the other medications used in RCTs, which included antidepressants (bupropion, mirtazapine, sertraline), antipsychotics (aripiprazole), anticonvulsants (topiramate, baclofen, gabapentin), naltrexone, varenicline, citicoline, ondansetron, prometa, riluzole, atomoxetine, dextroamphetamine, and modafinil. Behavioral treatments A 2018 systematic review and network meta-analysis of 50 trials involving 12 different psychosocial interventions for amphetamine, methamphetamine, or cocaine addiction found that combination therapy with both contingency management and community reinforcement approach had the highest efficacy (i.e., abstinence rate) and acceptability (i.e., lowest dropout rate). Other treatment modalities examined in the analysis included monotherapy with contingency management or community reinforcement approach, cognitive behavioral therapy, 12-step programs, non-contingent reward-based therapies, psychodynamic therapy, and other combination therapies involving these. Additionally, research on the neurobiological effects of physical exercise suggests that daily aerobic exercise, especially endurance exercise (e.g., marathon running), prevents the development of drug addiction and is an effective adjunct therapy (i.e., a supplemental treatment) for amphetamine addiction. Exercise leads to better treatment outcomes when used as an adjunct treatment, particularly for psychostimulant addictions. In particular, aerobic exercise decreases psychostimulant self-administration, reduces the reinstatement (i.e., relapse) of drug-seeking, and induces increased dopamine receptor D2 (DRD2) density in the striatum. This is the opposite of pathological stimulant use, which induces decreased striatal DRD2 density. One review noted that exercise may also prevent the development of a drug addiction by altering ΔFosB or immunoreactivity in the striatum or other parts of the reward system. Dependence and withdrawal Drug tolerance develops rapidly in amphetamine abuse (i.e., recreational amphetamine use), so periods of extended abuse require increasingly larger doses of the drug in order to achieve the same effect. According to a Cochrane review on withdrawal in individuals who compulsively use amphetamine and methamphetamine, "when chronic heavy users abruptly discontinue amphetamine use, many report a time-limited withdrawal syndrome that occurs within 24 hours of their last dose." This review noted that withdrawal symptoms in chronic, high-dose users are frequent, occurring in roughly 88% of cases, and persist for  weeks with a marked "crash" phase occurring during the first week. Amphetamine withdrawal symptoms can include anxiety, drug craving, depressed mood, fatigue, increased appetite, increased movement or decreased movement, lack of motivation, sleeplessness or sleepiness, and lucid dreams. The review indicated that the severity of withdrawal symptoms is positively correlated with the age of the individual and the extent of their dependence. Mild withdrawal symptoms from the discontinuation of amphetamine treatment at therapeutic doses can be avoided by tapering the dose. Overdose An amphetamine overdose can lead to many different symptoms, but is rarely fatal with appropriate care. The severity of overdose symptoms increases with dosage and decreases with drug tolerance to amphetamine. Tolerant individuals have been known to take as much as 5 grams of amphetamine in a day, which is roughly 100 times the maximum daily therapeutic dose. Symptoms of a moderate and extremely large overdose are listed below; fatal amphetamine poisoning usually also involves convulsions and coma. In 2013, overdose on amphetamine, methamphetamine, and other compounds implicated in an "amphetamine use disorder" resulted in an estimated 3,788 deaths worldwide ( deaths, 95% confidence). Toxicity In rodents and primates, sufficiently high doses of amphetamine cause dopaminergic neurotoxicity, or damage to dopamine neurons, which is characterized by dopamine terminal degeneration and reduced transporter and receptor function. There is no evidence that amphetamine is directly neurotoxic in humans. However, large doses of amphetamine may indirectly cause dopaminergic neurotoxicity as a result of hyperpyrexia, the excessive formation of reactive oxygen species, and increased autoxidation of dopamine. Animal models of neurotoxicity from high-dose amphetamine exposure indicate that the occurrence of hyperpyrexia (i.e., core body temperature ≥ 40 °C) is necessary for the development of amphetamine-induced neurotoxicity. Prolonged elevations of brain temperature above 40 °C likely promote the development of amphetamine-induced neurotoxicity in laboratory animals by facilitating the production of reactive oxygen species, disrupting cellular protein function, and transiently increasing blood–brain barrier permeability. Psychosis An amphetamine overdose can result in a stimulant psychosis that may involve a variety of symptoms, such as delusions and paranoia. A Cochrane review on treatment for amphetamine, dextroamphetamine, and methamphetamine psychosis states that about of users fail to recover completely. According to the same review, there is at least one trial that shows antipsychotic medications effectively resolve the symptoms of acute amphetamine psychosis. Psychosis rarely arises from therapeutic use. Drug interactions Many types of substances are known to interact with amphetamine, resulting in altered drug action or metabolism of amphetamine, the interacting substance, or both. Inhibitors of enzymes that metabolize amphetamine (e.g., CYP2D6 and FMO3) will prolong its elimination half-life, meaning that its effects will last longer. Amphetamine also interacts with , particularly monoamine oxidase A inhibitors, since both MAOIs and amphetamine increase plasma catecholamines (i.e., norepinephrine and dopamine); therefore, concurrent use of both is dangerous. Amphetamine modulates the activity of most psychoactive drugs. In particular, amphetamine may decrease the effects of sedatives and depressants and increase the effects of stimulants and antidepressants. Amphetamine may also decrease the effects of antihypertensives and antipsychotics due to its effects on blood pressure and dopamine respectively. Zinc supplementation may reduce the minimum effective dose of amphetamine when it is used for the treatment of ADHD. In general, there is no significant interaction when consuming amphetamine with food, but the pH of gastrointestinal content and urine affects the absorption and excretion of amphetamine, respectively. Acidic substances reduce the absorption of amphetamine and increase urinary excretion, and alkaline substances do the opposite. Due to the effect pH has on absorption, amphetamine also interacts with gastric acid reducers such as proton pump inhibitors and H2 antihistamines, which increase gastrointestinal pH (i.e., make it less acidic). Pharmacology Pharmacodynamics Amphetamine exerts its behavioral effects by altering the use of monoamines as neuronal signals in the brain, primarily in catecholamine neurons in the reward and executive function pathways of the brain. The concentrations of the main neurotransmitters involved in reward circuitry and executive functioning, dopamine and norepinephrine, increase dramatically in a dose-dependent manner by amphetamine because of its effects on monoamine transporters. The reinforcing and motivational salience-promoting effects of amphetamine are due mostly to enhanced dopaminergic activity in the mesolimbic pathway. The euphoric and locomotor-stimulating effects of amphetamine are dependent upon the magnitude and speed by which it increases synaptic dopamine and norepinephrine concentrations in the striatum. Amphetamine has been identified as a potent full agonist of trace amine-associated receptor 1 (TAAR1), a and G protein-coupled receptor (GPCR) discovered in 2001, which is important for regulation of brain monoamines. Activation of increases production via adenylyl cyclase activation and inhibits monoamine transporter function. Monoamine autoreceptors (e.g., D2 short, presynaptic α2, and presynaptic 5-HT1A) have the opposite effect of TAAR1, and together these receptors provide a regulatory system for monoamines. Notably, amphetamine and trace amines possess high binding affinities for TAAR1, but not for monoamine autoreceptors. Imaging studies indicate that monoamine reuptake inhibition by amphetamine and trace amines is site specific and depends upon the presence of TAAR1 in the associated monoamine neurons. In addition to the neuronal monoamine transporters, amphetamine also inhibits both vesicular monoamine transporters, VMAT1 and VMAT2, as well as SLC1A1, SLC22A3, and SLC22A5. SLC1A1 is excitatory amino acid transporter 3 (EAAT3), a glutamate transporter located in neurons, SLC22A3 is an extraneuronal monoamine transporter that is present in astrocytes, and SLC22A5 is a high-affinity carnitine transporter. Amphetamine is known to strongly induce cocaine- and amphetamine-regulated transcript (CART) gene expression, a neuropeptide involved in feeding behavior, stress, and reward, which induces observable increases in neuronal development and survival in vitro. The CART receptor has yet to be identified, but there is significant evidence that CART binds to a unique . Amphetamine also inhibits monoamine oxidases at very high doses, resulting in less monoamine and trace amine metabolism and consequently higher concentrations of synaptic monoamines. In humans, the only post-synaptic receptor at which amphetamine is known to bind is the receptor, where it acts as an agonist with low micromolar affinity. The full profile of amphetamine's short-term drug effects in humans is mostly derived through increased cellular communication or neurotransmission of dopamine, serotonin, norepinephrine, epinephrine, histamine, CART peptides, endogenous opioids, adrenocorticotropic hormone, corticosteroids, and glutamate, which it affects through interactions with , , , , , , and possibly other biological targets. Amphetamine also activates seven human carbonic anhydrase enzymes, several of which are expressed in the human brain. Dextroamphetamine is a more potent agonist of than levoamphetamine. Consequently, dextroamphetamine produces greater stimulation than levoamphetamine, roughly three to four times more, but levoamphetamine has slightly stronger cardiovascular and peripheral effects. Dopamine In certain brain regions, amphetamine increases the concentration of dopamine in the synaptic cleft. Amphetamine can enter the presynaptic neuron either through or by diffusing across the neuronal membrane directly. As a consequence of DAT uptake, amphetamine produces competitive reuptake inhibition at the transporter. Upon entering the presynaptic neuron, amphetamine activates which, through protein kinase A (PKA) and protein kinase C (PKC) signaling, causes DAT phosphorylation. Phosphorylation by either protein kinase can result in DAT internalization ( reuptake inhibition), but phosphorylation alone induces the reversal of dopamine transport through DAT (i.e., dopamine efflux). Amphetamine is also known to increase intracellular calcium, an effect which is associated with DAT phosphorylation through an unidentified Ca2+/calmodulin-dependent protein kinase (CAMK)-dependent pathway, in turn producing dopamine efflux. Through direct activation of G protein-coupled inwardly-rectifying potassium channels, reduces the firing rate of dopamine neurons, preventing a hyper-dopaminergic state. Amphetamine is also a substrate for the presynaptic vesicular monoamine transporter, . Following amphetamine uptake at VMAT2, amphetamine induces the collapse of the vesicular pH gradient, which results in the release of dopamine molecules from synaptic vesicles into the cytosol via dopamine efflux through VMAT2. Subsequently, the cytosolic dopamine molecules are released from the presynaptic neuron into the synaptic cleft via reverse transport at . Norepinephrine Similar to dopamine, amphetamine dose-dependently increases the level of synaptic norepinephrine, the direct precursor of epinephrine. Based upon neuronal expression, amphetamine is thought to affect norepinephrine analogously to dopamine. In other words, amphetamine induces TAAR1-mediated efflux and reuptake inhibition at phosphorylated , competitive NET reuptake inhibition, and norepinephrine release from . Serotonin Amphetamine exerts analogous, yet less pronounced, effects on serotonin as on dopamine and norepinephrine. Amphetamine affects serotonin via and, like norepinephrine, is thought to phosphorylate via . Like dopamine, amphetamine has low, micromolar affinity at the human 5-HT1A receptor. Other neurotransmitters, peptides, hormones, and enzymes Acute amphetamine administration in humans increases endogenous opioid release in several brain structures in the reward system. Extracellular levels of glutamate, the primary excitatory neurotransmitter in the brain, have been shown to increase in the striatum following exposure to amphetamine. This increase in extracellular glutamate presumably occurs via the amphetamine-induced internalization of EAAT3, a glutamate reuptake transporter, in dopamine neurons. Amphetamine also induces the selective release of histamine from mast cells and efflux from histaminergic neurons through . Acute amphetamine administration can also increase adrenocorticotropic hormone and corticosteroid levels in blood plasma by stimulating the hypothalamic–pituitary–adrenal axis. In December 2017, the first study assessing the interaction between amphetamine and human carbonic anhydrase enzymes was published; of the eleven carbonic anhydrase enzymes it examined, it found that amphetamine potently activates seven, four of which are highly expressed in the human brain, with low nanomolar through low micromolar activating effects. Based upon preclinical research, cerebral carbonic anhydrase activation has cognition-enhancing effects; but, based upon the clinical use of carbonic anhydrase inhibitors, carbonic anhydrase activation in other tissues may be associated with adverse effects, such as ocular activation exacerbating glaucoma. Pharmacokinetics The oral bioavailability of amphetamine varies with gastrointestinal pH; it is well absorbed from the gut, and bioavailability is typically over 75% for dextroamphetamine. Amphetamine is a weak base with a pKa of 9.9; consequently, when the pH is basic, more of the drug is in its lipid soluble free base form, and more is absorbed through the lipid-rich cell membranes of the gut epithelium. Conversely, an acidic pH means the drug is predominantly in a water-soluble cationic (salt) form, and less is absorbed. Approximately of amphetamine circulating in the bloodstream is bound to plasma proteins. Following absorption, amphetamine readily distributes into most tissues in the body, with high concentrations occurring in cerebrospinal fluid and brain tissue. The half-lives of amphetamine enantiomers differ and vary with urine pH. At normal urine pH, the half-lives of dextroamphetamine and levoamphetamine are  hours and  hours, respectively. Highly acidic urine will reduce the enantiomer half-lives to 7 hours; highly alkaline urine will increase the half-lives up to 34 hours. The immediate-release and extended release variants of salts of both isomers reach peak plasma concentrations at 3 hours and 7 hours post-dose respectively. Amphetamine is eliminated via the kidneys, with of the drug being excreted unchanged at normal urinary pH. When the urinary pH is basic, amphetamine is in its free base form, so less is excreted. When urine pH is abnormal, the urinary recovery of amphetamine may range from a low of 1% to a high of 75%, depending mostly upon whether urine is too basic or acidic, respectively. Following oral administration, amphetamine appears in urine within 3 hours. Roughly 90% of ingested amphetamine is eliminated 3 days after the last oral dose. CYP2D6, dopamine β-hydroxylase (DBH), flavin-containing monooxygenase 3 (FMO3), butyrate-CoA ligase (XM-ligase), and glycine N-acyltransferase (GLYAT) are the enzymes known to metabolize amphetamine or its metabolites in humans. Amphetamine has a variety of excreted metabolic products, including , , , benzoic acid, hippuric acid, norephedrine, and phenylacetone. Among these metabolites, the active sympathomimetics are , , and norephedrine. The main metabolic pathways involve aromatic para-hydroxylation, aliphatic alpha- and beta-hydroxylation, N-oxidation, N-dealkylation, and deamination. The known metabolic pathways, detectable metabolites, and metabolizing enzymes in humans include the following: Pharmacomicrobiomics The human metagenome (i.e., the genetic composition of an individual and all microorganisms that reside on or within the individual's body) varies considerably between individuals. Since the total number of microbial and viral cells in the human body (over 100 trillion) greatly outnumbers human cells (tens of trillions), there is considerable potential for interactions between drugs and an individual's microbiome, including: drugs altering the composition of the human microbiome, drug metabolism by microbial enzymes modifying the drug's pharmacokinetic profile, and microbial drug metabolism affecting a drug's clinical efficacy and toxicity profile. The field that studies these interactions is known as pharmacomicrobiomics. Similar to most biomolecules and other orally administered xenobiotics (i.e., drugs), amphetamine is predicted to undergo promiscuous metabolism by human gastrointestinal microbiota (primarily bacteria) prior to absorption into the blood stream. The first amphetamine-metabolizing microbial enzyme, tyramine oxidase from a strain of E. coli commonly found in the human gut, was identified in 2019. This enzyme was found to metabolize amphetamine, tyramine, and phenethylamine with roughly the same binding affinity for all three compounds. Related endogenous compounds Amphetamine has a very similar structure and function to the endogenous trace amines, which are naturally occurring neuromodulator molecules produced in the human body and brain. Among this group, the most closely related compounds are phenethylamine, the parent compound of amphetamine, and , an isomer of amphetamine (i.e., it has an identical molecular formula). In humans, phenethylamine is produced directly from by the aromatic amino acid decarboxylase (AADC) enzyme, which converts into dopamine as well. In turn, is metabolized from phenethylamine by phenylethanolamine N-methyltransferase, the same enzyme that metabolizes norepinephrine into epinephrine. Like amphetamine, both phenethylamine and regulate monoamine neurotransmission via ; unlike amphetamine, both of these substances are broken down by monoamine oxidase B, and therefore have a shorter half-life than amphetamine. Chemistry Amphetamine is a methyl homolog of the mammalian neurotransmitter phenethylamine with the chemical formula . The carbon atom adjacent to the primary amine is a stereogenic center, and amphetamine is composed of a racemic 1:1 mixture of two enantiomers. This racemic mixture can be separated into its optical isomers: levoamphetamine and dextroamphetamine. At room temperature, the pure free base of amphetamine is a mobile, colorless, and volatile liquid with a characteristically strong amine odor, and acrid, burning taste. Frequently prepared solid salts of amphetamine include amphetamine adipate, aspartate, hydrochloride, phosphate, saccharate, sulfate, and tannate. Dextroamphetamine sulfate is the most common enantiopure salt. Amphetamine is also the parent compound of its own structural class, which includes a number of psychoactive derivatives. In organic chemistry, amphetamine is an excellent chiral ligand for the stereoselective synthesis of . Substituted derivatives The substituted derivatives of amphetamine, or "substituted amphetamines", are a broad range of chemicals that contain amphetamine as a "backbone"; specifically, this chemical class includes derivative compounds that are formed by replacing one or more hydrogen atoms in the amphetamine core structure with substituents. The class includes amphetamine itself, stimulants like methamphetamine, serotonergic empathogens like MDMA, and decongestants like ephedrine, among other subgroups. Synthesis Since the first preparation was reported in 1887, numerous synthetic routes to amphetamine have been developed. The most common route of both legal and illicit amphetamine synthesis employs a non-metal reduction known as the Leuckart reaction (method 1). In the first step, a reaction between phenylacetone and formamide, either using additional formic acid or formamide itself as a reducing agent, yields . This intermediate is then hydrolyzed using hydrochloric acid, and subsequently basified, extracted with organic solvent, concentrated, and distilled to yield the free base. The free base is then dissolved in an organic solvent, sulfuric acid added, and amphetamine precipitates out as the sulfate salt. A number of chiral resolutions have been developed to separate the two enantiomers of amphetamine. For example, racemic amphetamine can be treated with to form a diastereoisomeric salt which is fractionally crystallized to yield dextroamphetamine. Chiral resolution remains the most economical method for obtaining optically pure amphetamine on a large scale. In addition, several enantioselective syntheses of amphetamine have been developed. In one example, optically pure is condensed with phenylacetone to yield a chiral Schiff base. In the key step, this intermediate is reduced by catalytic hydrogenation with a transfer of chirality to the carbon atom alpha to the amino group. Cleavage of the benzylic amine bond by hydrogenation yields optically pure dextroamphetamine. A large number of alternative synthetic routes to amphetamine have been developed based on classic organic reactions. One example is the Friedel–Crafts alkylation of benzene by allyl chloride to yield beta chloropropylbenzene which is then reacted with ammonia to produce racemic amphetamine (method 2). Another example employs the Ritter reaction (method 3). In this route, allylbenzene is reacted acetonitrile in sulfuric acid to yield an organosulfate which in turn is treated with sodium hydroxide to give amphetamine via an acetamide intermediate. A third route starts with which through a double alkylation with methyl iodide followed by benzyl chloride can be converted into acid. This synthetic intermediate can be transformed into amphetamine using either a Hofmann or Curtius rearrangement (method 4). A significant number of amphetamine syntheses feature a reduction of a nitro, imine, oxime, or other nitrogen-containing functional groups. In one such example, a Knoevenagel condensation of benzaldehyde with nitroethane yields . The double bond and nitro group of this intermediate is reduced using either catalytic hydrogenation or by treatment with lithium aluminium hydride (method 5). Another method is the reaction of phenylacetone with ammonia, producing an imine intermediate that is reduced to the primary amine using hydrogen over a palladium catalyst or lithium aluminum hydride (method 6). Detection in body fluids Amphetamine is frequently measured in urine or blood as part of a drug test for sports, employment, poisoning diagnostics, and forensics. Techniques such as immunoassay, which is the most common form of amphetamine test, may cross-react with a number of sympathomimetic drugs. Chromatographic methods specific for amphetamine are employed to prevent false positive results. Chiral separation techniques may be employed to help distinguish the source of the drug, whether prescription amphetamine, prescription amphetamine prodrugs, (e.g., selegiline), over-the-counter drug products that contain levomethamphetamine, or illicitly obtained substituted amphetamines. Several prescription drugs produce amphetamine as a metabolite, including benzphetamine, clobenzorex, famprofazone, fenproporex, lisdexamfetamine, mesocarb, methamphetamine, prenylamine, and selegiline, among others. These compounds may produce positive results for amphetamine on drug tests. Amphetamine is generally only detectable by a standard drug test for approximately 24 hours, although a high dose may be detectable for  days. For the assays, a study noted that an enzyme multiplied immunoassay technique (EMIT) assay for amphetamine and methamphetamine may produce more false positives than liquid chromatography–tandem mass spectrometry. Gas chromatography–mass spectrometry (GC–MS) of amphetamine and methamphetamine with the derivatizing agent chloride allows for the detection of methamphetamine in urine. GC–MS of amphetamine and methamphetamine with the chiral derivatizing agent Mosher's acid chloride allows for the detection of both dextroamphetamine and dextromethamphetamine in urine. Hence, the latter method may be used on samples that test positive using other methods to help distinguish between the various sources of the drug. History, society, and culture Amphetamine was first synthesized in 1887 in Germany by Romanian chemist Lazăr Edeleanu who named it phenylisopropylamine; its stimulant effects remained unknown until 1927, when it was independently resynthesized by Gordon Alles and reported to have sympathomimetic properties. Amphetamine had no medical use until late 1933, when Smith, Kline and French began selling it as an inhaler under the brand name Benzedrine as a decongestant. Benzedrine sulfate was introduced 3 years later and was used to treat a wide variety of medical conditions, including narcolepsy, obesity, low blood pressure, low libido, and chronic pain, among others. During World War II, amphetamine and methamphetamine were used extensively by both the Allied and Axis forces for their stimulant and performance-enhancing effects. As the addictive properties of the drug became known, governments began to place strict controls on the sale of amphetamine. For example, during the early 1970s in the United States, amphetamine became a schedule II controlled substance under the Controlled Substances Act. In spite of strict government controls, amphetamine has been used legally or illicitly by people from a variety of backgrounds, including authors, musicians, mathematicians, and athletes. Amphetamine is still illegally synthesized today in clandestine labs and sold on the black market, primarily in European countries. Among European Union (EU) member states 11.9 million adults of ages have used amphetamine or methamphetamine at least once in their lives and 1.7 million have used either in the last year. During 2012, approximately 5.9 metric tons of illicit amphetamine were seized within EU member states; the "street price" of illicit amphetamine within the EU ranged from  per gram during the same period. Outside Europe, the illicit market for amphetamine is much smaller than the market for methamphetamine and MDMA. Legal status As a result of the United Nations 1971 Convention on Psychotropic Substances, amphetamine became a schedule II controlled substance, as defined in the treaty, in all 183 state parties. Consequently, it is heavily regulated in most countries. Some countries, such as South Korea and Japan, have banned substituted amphetamines even for medical use. In other nations, such as Canada (schedule I drug), the Netherlands (List I drug), the United States (schedule II drug), Australia (schedule 8), Thailand (category 1 narcotic), and United Kingdom (class B drug), amphetamine is in a restrictive national drug schedule that allows for its use as a medical treatment. Pharmaceutical products Several currently marketed amphetamine formulations contain both enantiomers, including those marketed under the brand names Adderall, Adderall XR, Mydayis, Adzenys ER, , Dyanavel XR, Evekeo, and Evekeo ODT. Of those, Evekeo (including Evekeo ODT) is the only product containing only racemic amphetamine (as amphetamine sulfate), and is therefore the only one whose active moiety can be accurately referred to simply as "amphetamine". Dextroamphetamine, marketed under the brand names Dexedrine and Zenzedi, is the only enantiopure amphetamine product currently available. A prodrug form of dextroamphetamine, lisdexamfetamine, is also available and is marketed under the brand name Vyvanse. As it is a prodrug, lisdexamfetamine is structurally different from dextroamphetamine, and is inactive until it metabolizes into dextroamphetamine. The free base of racemic amphetamine was previously available as Benzedrine, Psychedrine, and Sympatedrine. Levoamphetamine was previously available as Cydril. Many current amphetamine pharmaceuticals are salts due to the comparatively high volatility of the free base. However, oral suspension and orally disintegrating tablet (ODT) dosage forms composed of the free base were introduced in 2015 and 2016, respectively. Some of the current brands and their generic equivalents are listed below.

Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called barrel artillery, cannon artillery or gun artillery) and rocket artillery. In common speech, the word "artillery" is often used to refer to individual devices, along with their accessories and fittings, although these assemblages are more properly called "equipment". However, there is no generally recognized generic term for a gun, howitzer, mortar, and so forth: the United States uses "artillery piece", but most English-speaking armies use "gun" and "mortar". The projectiles fired are typically either "shot" (if solid) or "shell" (if not solid). Historically, variants of solid shot including canister, chain shot and grapeshot were also used. "Shell" is a widely used generic term for a projectile, which is a component of munitions. By association, artillery may also refer to the arm of service that customarily operates such engines. In some armies, the artillery arm has operated field, coastal, anti-aircraft, and anti-tank artillery; in others these have been separate arms, and with some nations coastal has been a naval or marine responsibility. In the 20th century, target acquisition devices (such as radar) and techniques (such as sound ranging and flash spotting) emerged, primarily for artillery. These are usually utilized by one or more of the artillery arms. The widespread adoption of indirect fire in the early 20th century introduced the need for specialist data for field artillery, notably survey and meteorological, and in some armies, provision of these are the responsibility of the artillery arm. The majority of combat deaths in the Napoleonic Wars, World War I, and World War II were caused by artillery. In 1944, Joseph Stalin said in a speech that artillery was "the god of war". Artillery piece Although not called by that name, siege engines performing the role recognizable as artillery have been employed in warfare since antiquity. The first known catapult was developed in Syracuse in 399 BC. Until the introduction of gunpowder into western warfare, artillery was dependent upon mechanical energy which not only severely limited the kinetic energy of the projectiles, it also required the construction of very large engines to accumulate sufficient energy. A 1st-century BC Roman catapult launching stones achieved a kinetic energy of 16 kilojoules, compared to a mid-19th-century 12-pounder gun, which fired a round, with a kinetic energy of 240 kilojoules, or a 20th-century US battleship that fired a projectile from its main battery with an energy level surpassing 350 megajoules. From the Middle Ages through most of the modern era, artillery pieces on land were moved by horse-drawn gun carriages. In the contemporary era, artillery pieces and their crew relied on wheeled or tracked vehicles as transportation. These land versions of artillery were dwarfed by railway guns; the largest of these large-calibre guns ever conceived – Project Babylon of the Supergun affair – was theoretically capable of putting a satellite into orbit. Artillery used by naval forces has also changed significantly, with missiles generally replacing guns in surface warfare. Over the course of military history, projectiles were manufactured from a wide variety of materials, into a wide variety of shapes, using many different methods in which to target structural/defensive works and inflict enemy casualties. The engineering applications for ordnance delivery have likewise changed significantly over time, encompassing some of the most complex and advanced technologies in use today. In some armies, the weapon of artillery is the projectile, not the equipment that fires it. The process of delivering fire onto the target is called gunnery. The actions involved in operating an artillery piece are collectively called "serving the gun" by the "detachment" or gun crew, constituting either direct or indirect artillery fire. The manner in which gunnery crews (or formations) are employed is called artillery support. At different periods in history, this may refer to weapons designed to be fired from ground-, sea-, and even air-based weapons platforms. Crew Some armed forces use the term "gunners" for the soldiers and sailors with the primary function of using artillery. The gunners and their guns are usually grouped in teams called either "crews" or "detachments". Several such crews and teams with other functions are combined into a unit of artillery, usually called a battery, although sometimes called a company. In gun detachments, each role is numbered, starting with "1" the Detachment Commander, and the highest number being the Coverer, the second-in-command. "Gunner" is also the lowest rank, and junior non-commissioned officers are "Bombardiers" in some artillery arms. Batteries are roughly equivalent to a company in the infantry, and are combined into larger military organizations for administrative and operational purposes, either battalions or regiments, depending on the army. These may be grouped into brigades; the Russian army also groups some brigades into artillery divisions, and the People's Liberation Army has artillery corps. The term "artillery" also designates a combat arm of most military services when used organizationally to describe units and formations of the national armed forces that operate the weapons. Tactics During military operations, field artillery has the role of providing support to other arms in combat or of attacking targets, particularly in-depth. Broadly, these effects fall into two categories, aiming either to suppress or neutralize the enemy, or to cause casualties, damage, and destruction. This is mostly achieved by delivering high-explosive munitions to suppress, or inflict casualties on the enemy from casing fragments and other debris and from blast, or by destroying enemy positions, equipment, and vehicles. Non-lethal munitions, notably smoke, can also suppress or neutralize the enemy by obscuring their view. Fire may be directed by an artillery observer or another observer, including crewed and uncrewed aircraft, or called onto map coordinates. Military doctrine has had a significant influence on the core engineering design considerations of artillery ordnance through its history, in seeking to achieve a balance between the delivered volume of fire with ordnance mobility. However, during the modern period, the consideration of protecting the gunners also arose due to the late-19th-century introduction of the new generation of infantry weapons using conoidal bullet, better known as the Minié ball, with a range almost as long as that of field artillery. The gunners' increasing proximity to and participation in direct combat against other combat arms and attacks by aircraft made the introduction of a gun shield necessary. The problems of how to employ a fixed or horse-towed gun in mobile warfare necessitated the development of new methods of transporting the artillery into combat. Two distinct forms of artillery were developed: the towed gun, used primarily to attack or defend a fixed-line; and the self-propelled gun, intended to accompany a mobile force and to provide continuous fire support and/or suppression. These influences have guided the development of artillery ordnance, systems, organizations, and operations until the present, with artillery systems capable of providing support at ranges from as little as 100 m to the intercontinental ranges of ballistic missiles. The only combat in which artillery is unable to take part is close-quarters combat, with the possible exception of artillery reconnaissance teams. Etymology The word as used in the current context originated in the Middle Ages. One suggestion is that it comes from French atelier, meaning the place where manual work is done. Another suggestion is that it originates from the 13th century and the Old French artillier, designating craftsmen and manufacturers of all materials and warfare equipments (spears, swords, armor, war machines); and, for the next 250 years, the sense of the word "artillery" covered all forms of military weapons. Hence, the naming of the Honourable Artillery Company, which was essentially an infantry unit until the 19th century. Another suggestion is that it comes from the Italian arte de tirare (art of shooting), coined by one of the first theorists on the use of artillery, Niccolò Tartaglia. History Mechanical systems used for throwing ammunition in ancient warfare, also known as "engines of war", like the catapult, onager, trebuchet, and ballista, are also referred to by military historians as artillery. Medieval During medieval times, more types of artillery were developed, most notably the trebuchet. Traction trebuchets, using manpower to launch projectiles, have been used in ancient China since the 4th century as anti-personnel weapons. However, in the 12th century, the counterweight trebuchet was introduced, with the earliest mention of it being in 1187. Invention of gunpowder Early Chinese artillery had vase-like shapes. This includes the "long range awe inspiring" cannon dated from 1350 and found in the 14th century Ming Dynasty treatise Huolongjing. With the development of better metallurgy techniques, later cannons abandoned the vase shape of early Chinese artillery. This change can be seen in the bronze "thousand ball thunder cannon", an early example of field artillery. These small, crude weapons diffused into the Middle East (the madfaa) and reached Europe in the 13th century, in a very limited manner. In Asia, Mongols adopted the Chinese artillery and used it effectively in the great conquest. By the late 14th century, Chinese rebels used organized artillery and cavalry to push Mongols out. As small smooth-bore barrels, these were initially cast in iron or bronze around a core, with the first drilled bore ordnance recorded in operation near Seville in 1247. They fired lead, iron, or stone balls, sometimes large arrows and on occasions simply handfuls of whatever scrap came to hand. During the Hundred Years' War, these weapons became more common, initially as the bombard and later the cannon. Cannon were always muzzle-loaders. While there were many early attempts at breech-loading designs, a lack of engineering knowledge rendered these even more dangerous to use than muzzle-loaders. Expansion of use In 1415, the Portuguese invaded the Mediterranean port town of Ceuta. While it is difficult to confirm the use of firearms in the siege of the city, it is known the Portuguese defended it thereafter with firearms, namely bombardas, colebratas, and falconetes. In 1419, Sultan Abu Sa'id led an army to reconquer the fallen city, and Marinids brought cannons and used them in the assault on Ceuta. Finally, hand-held firearms and riflemen appear in Morocco, in 1437, in an expedition against the people of Tangiers. It is clear these weapons had developed into several different forms, from small guns to large artillery pieces. The artillery revolution in Europe caught on during the Hundred Years' War and changed the way that battles were fought. In the preceding decades, the English had even used a gunpowder-like weapon in military campaigns against the Scottish. However, at this time, the cannons used in battle were very small and not particularly powerful. Cannons were only useful for the defense of a castle, as demonstrated at Breteuil in 1356, when the besieged English used a cannon to destroy an attacking French assault tower. By the end of the 14th century, cannon were only powerful enough to knock in roofs, and could not penetrate castle walls. However, a major change occurred between 1420 and 1430, when artillery became much more powerful and could now batter strongholds and fortresses quite efficiently. The English, French, and Burgundians all advanced in military technology, and as a result the traditional advantage that went to the defense in a siege was lost. The cannon during this period were elongated, and the recipe for gunpowder was improved to make it three times as powerful as before. These changes led to the increased power in the artillery weapons of the time. Joan of Arc encountered gunpowder weaponry several times. When she led the French against the English at the Battle of Tourelles, in 1430, she faced heavy gunpowder fortifications, and yet her troops prevailed in that battle. In addition, she led assaults against the English-held towns of Jargeau, Meung, and Beaugency, all with the support of large artillery units. When she led the assault on Paris, Joan faced stiff artillery fire, especially from the suburb of St. Denis, which ultimately led to her defeat in this battle. In April 1430, she went to battle against the Burgundians, whose support was purchased by the English. At this time, the Burgundians had the strongest and largest gunpowder arsenal among the European powers, and yet the French, under Joan of Arc's leadership, were able to beat back the Burgundians and defend themselves. As a result, most of the battles of the Hundred Years' War that Joan of Arc participated in were fought with gunpowder artillery. The army of Mehmet the Conqueror, which conquered Constantinople in 1453, included both artillery and foot soldiers armed with gunpowder weapons. The Ottomans brought to the siege sixty-nine guns in fifteen separate batteries and trained them at the walls of the city. The barrage of Ottoman cannon fire lasted forty days, and they are estimated to have fired 19,320 times. Artillery also played a decisive role in the Battle of St. Jakob an der Birs of 1444. Early cannon were not always reliable; King James II of Scotland was killed by the accidental explosion of one of his own cannon, imported from Flanders, at the siege of Roxburgh Castle in 1460. The able use of artillery supported to a large measure the expansion and defense of the Portuguese Empire, as it was a necessary tool that allowed the Portuguese to face overwhelming odds both on land and sea from Morocco to Asia. In great sieges and in sea battles, the Portuguese demonstrated a level of proficiency in the use of artillery after the beginning of the 16th century unequalled by contemporary European neighbours, in part due to the experience gained in intense fighting in Morocco, which served as a proving ground for artillery and its practical application, and made Portugal a forerunner in gunnery for decades. During the reign of King Manuel (1495–1521) at least 2017 cannon were sent to Morocco for garrison defense, with more than 3000 cannon estimated to have been required during that 26 year period. An especially noticeable division between siege guns and anti-personnel guns inhanced the use and effectiveness of Portuguese firearms above contemporary powers, making cannon the most essential element in the Portuguese arsenal. The three major classes of Portuguese artillery were anti-personnel guns with a high borelength (including: rebrodequim, berço, falconete, falcão, sacre, áspide, cão, serpentina and passavolante); bastion guns which could batter fortifications (camelete, leão, pelicano, basilisco, águia, camelo, roqueira, urso); and howitzers that fired large stone cannonballs in an elevated arch, weighted up to 4000 pounds and could fire incendiary devices, such as a hollow iron ball filled with pitch and fuse, designed to be fired at close range and burst on contact. The most popular in Portuguese arsenals was the berço, a 5cm, one pounder bronze breech-loading cannon that weighted 150kg with an effective range of 600 meters. A tactical innovation the Portuguese introduced in fort defense was the use of combinations of projectiles against massed assaults. Although canister shot had been developed in the early 15th century, the Portuguese were the first to employ it extensively, and Portuguese engineers invented a canister round which consisted of a thin lead case filled with iron pellets, that broke up at the muzzle and scattered its contents in a narrow pattern. An innovation which Portugal adopted in advance of other European powers was fuse-delayed action shells, and were commonly used in 1505. Although dangerous, their effectiveness meant a sixth of all rounds used by the Portuguese in Morocco were of the fused-shell variety. The new Ming Dynasty established the "Divine Engine Battalion" (神机营), which specialized in various types of artillery. Light cannons and cannons with multiple volleys were developed. In a campaign to suppress a local minority rebellion near today's Burmese border, "the Ming army used a 3-line method of arquebuses/muskets to destroy an elephant formation." When the Portuguese and Spanish arrived at Southeast Asia, they found that the local kingdoms were already using cannons. Portuguese and Spanish invaders were unpleasantly surprised and even outgunned on occasion. Duarte Barbosa ca. 1514 said that the inhabitants of Java were great masters in casting artillery and very good artillerymen. They made many one-pounder cannons (cetbang or rentaka), long muskets, spingarde (arquebus), schioppi (hand cannon), Greek fire, guns (cannons), and other fire-works. Every place was considered excellent in casting artillery, and in the knowledge of using it. In 1513, the Javanese fleet led by Pati Unus sailed to attack Portuguese Malacca "with much artillery made in Java, for the Javanese are skilled in founding and casting, and in all works in iron, over and above what they have in India". By the early 16th century, the Javanese already locally-producing large guns, some of them still survived until the present day and dubbed as "sacred cannon" or "holy cannon". These cannons varied between 180 and 260 pounders, weighing anywhere between 3–8 tons, measuring between 3–6 m. Between 1593 and 1597, about 200,000 Korean and Chinese troops which fought against Japan in Korea actively used heavy artillery in both siege and field combat. Korean forces mounted artillery in ships as naval guns, providing an advantage against Japanese navy which used Kunikuzushi (国崩し – Japanese breech-loading swivel gun) and Ōzutsu (大筒 – large size Tanegashima) as their largest firearms. Smoothbores Bombards were of value mainly in sieges. A famous Turkish example used at the siege of Constantinople in 1453 weighed 19 tons, took 200 men and sixty oxen to emplace, and could fire just seven times a day. The Fall of Constantinople was perhaps "the first event of supreme importance whose result was determined by the use of artillery" when the huge bronze cannons of Mehmed II breached the city's walls, ending the Byzantine Empire, according to Sir Charles Oman. Bombards developed in Europe were massive smoothbore weapons distinguished by their lack of a field carriage, immobility once emplaced, highly individual design, and noted unreliability (in 1460 James II, King of Scots, was killed when one exploded at the siege of Roxburgh). Their large size precluded the barrels being cast and they were constructed out of metal staves or rods bound together with hoops like a barrel, giving their name to the gun barrel. The use of the word "cannon" marks the introduction in the 15th century of a dedicated field carriage with axle, trail and animal-drawn limber—this produced mobile field pieces that could move and support an army in action, rather than being found only in the siege and static defenses. The reduction in the size of the barrel was due to improvements in both iron technology and gunpowder manufacture, while the development of trunnions—projections at the side of the cannon as an integral part of the cast—allowed the barrel to be fixed to a more movable base, and also made raising or lowering the barrel much easier. The first land-based mobile weapon is usually credited to Jan Žižka, who deployed his oxen-hauled cannon during the Hussite Wars of Bohemia (1418–1424). However, cannons were still large and cumbersome. With the rise of musketry in the 16th century, cannon were largely (though not entirely) displaced from the battlefield—the cannon were too slow and cumbersome to be used and too easily lost to a rapid enemy advance. The combining of shot and powder into a single unit, a cartridge, occurred in the 1620s with a simple fabric bag, and was quickly adopted by all nations. It speeded loading and made it safer, but unexpelled bag fragments were an additional fouling in the gun barrel and a new tool—a worm—was introduced to remove them. Gustavus Adolphus is identified as the general who made cannon an effective force on the battlefield—pushing the development of much lighter and smaller weapons and deploying them in far greater numbers than previously. The outcome of battles was still determined by the clash of infantry. Shells, explosive-filled fused projectiles, were in use by the 15th century. The development of specialized pieces—shipboard artillery, howitzers and mortars—was also begun in this period. More esoteric designs, like the multi-barrel ribauldequin (known as "organ guns"), were also produced. The 1650 book by Kazimierz Siemienowicz Artis Magnae Artilleriae pars prima was one of the most important contemporary publications on the subject of artillery. For over two centuries this work was used in Europe as a basic artillery manual. One of the most significant effects of artillery during this period was however somewhat more indirect—by easily reducing to rubble any medieval-type fortification or city wall (some which had stood since Roman times), it abolished millennia of siege-warfare strategies and styles of fortification building. This led, among other things, to a frenzy of new bastion-style fortifications to be built all over Europe and in its colonies, but also had a strong integrating effect on emerging nation-states, as kings were able to use their newfound artillery superiority to force any local dukes or lords to submit to their will, setting the stage for the absolutist kingdoms to come. Modern rocket artillery can trace its heritage back to the Mysorean rockets of India. Their first recorded use was in 1780 during the battles of the Second, Third and Fourth Mysore Wars. The wars fought between the British East India Company and the Kingdom of Mysore in India made use of the rockets as a weapon. In the Battle of Pollilur, the Siege of Seringapatam (1792) and in Battle of Seringapatam in 1799, these rockets were used with considerable effect against the British. After the wars, several Mysore rockets were sent to England, but experiments with heavier payloads were unsuccessful. In 1804 William Congreve, considering the Mysorian rockets to have too short a range (less than 1,000 yards) developed rockets in numerous sizes with ranges up to 3,000 yards and eventually utilizing iron casing as the Congreve rocket which were used effectively during the Napoleonic Wars and the War of 1812. Napoleonic With the Napoleonic Wars, artillery experienced changes in both physical design and operation. Rather than being overseen by "mechanics", artillery was viewed as its own service branch with the capability of dominating the battlefield. The success of the French artillery companies was at least in part due to the presence of specially trained artillery officers leading and coordinating during the chaos of battle. Napoleon, himself a former artillery officer, perfected the tactic of massed artillery batteries unleashed upon a critical point in his enemies' line as a prelude to a decisive infantry and cavalry assault. Physically, cannons continued to become smaller and lighter. During the Seven Years War, King Frederick II of Prussia used these advances to deploy horse artillery that could move throughout the battlefield. Frederick also introduced the reversible iron ramrod, which was much more resistant to breakage than older wooden designs. The reversibility aspect also helped increase the rate of fire, since a soldier would no longer have to worry about what end of the ramrod they were using. Jean-Baptiste de Gribeauval, a French artillery engineer, introduced the standardization of cannon design in the mid-18th century. He developed a 6-inch (150 mm) field howitzer whose gun barrel, carriage assembly and ammunition specifications were made uniform for all French cannons. The standardized interchangeable parts of these cannons down to the nuts, bolts and screws made their mass production and repair much easier. While the Gribeauval system made for more efficient production and assembly, the carriages used were heavy and the gunners were forced to march on foot (instead of riding on the limber and gun as in the British system). Each cannon was named for the weight of its projectiles, giving us variants such as 4, 8, and 12, indicating the weight in pounds. The projectiles themselves included solid balls or canister containing lead bullets or other material. These canister shots acted as massive shotguns, peppering the target with hundreds of projectiles at close range. The solid balls, known as round shot, was most effective when fired at shoulder-height across a flat, open area. The ball would tear through the ranks of the enemy or bounce along the ground breaking legs and ankles. Modern The development of modern artillery occurred in the mid to late 19th century as a result of the convergence of various improvements in the underlying technology. Advances in metallurgy allowed for the construction of breech-loading rifled guns that could fire at a much greater muzzle velocity. After the British artillery was shown up in the Crimean War as having barely changed since the Napoleonic Wars, the industrialist William Armstrong was awarded a contract by the government to design a new piece of artillery. Production started in 1855 at the Elswick Ordnance Company and the Royal Arsenal at Woolwich, and the outcome was the revolutionary Armstrong Gun, which marked the birth of modern artillery. Three of its features particularly stand out. First, the piece was rifled, which allowed for a much more accurate and powerful action. Although rifling had been tried on small arms since the 15th century, the necessary machinery to accurately rifle artillery was not available until the mid-19th century. Martin von Wahrendorff, and Joseph Whitworth independently produced rifled cannon in the 1840s, but it was Armstrong's gun that was first to see widespread use during the Crimean War. The cast iron shell of the Armstrong gun was similar in shape to a Minié ball and had a thin lead coating which made it fractionally larger than the gun's bore and which engaged with the gun's rifling grooves to impart spin to the shell. This spin, together with the elimination of windage as a result of the tight fit, enabled the gun to achieve greater range and accuracy than existing smooth-bore muzzle-loaders with a smaller powder charge. His gun was also a breech-loader. Although attempts at breech-loading mechanisms had been made since medieval times, the essential engineering problem was that the mechanism could not withstand the explosive charge. It was only with the advances in metallurgy and precision engineering capabilities during the Industrial Revolution that Armstrong was able to construct a viable solution. The gun combined all the properties that make up an effective artillery piece. The gun was mounted on a carriage in such a way as to return the gun to firing position after the recoil. What made the gun really revolutionary lay in the technique of the construction of the gun barrel that allowed it to withstand much more powerful explosive forces. The "built-up" method involved assembling the barrel with wrought-iron (later mild steel was used) tubes of successively smaller diameter. The tube would then be heated to allow it to expand and fit over the previous tube. When it cooled the gun would contract although not back to its original size, which allowed an even pressure along the walls of the gun which was directed inward against the outward forces that the gun's firing exerted on the barrel. Another innovative feature, more usually associated with 20th-century guns, was what Armstrong called its "grip", which was essentially a squeeze bore; the 6 inches of the bore at the muzzle end was of slightly smaller diameter, which centered the shell before it left the barrel and at the same time slightly swaged down its lead coating, reducing its diameter and slightly improving its ballistic qualities. Armstrong's system was adopted in 1858, initially for "special service in the field" and initially he produced only smaller artillery pieces, 6-pounder (2.5 in/64 mm) mountain or light field guns, 9-pounder (3 in/76 mm) guns for horse artillery, and 12-pounder (3 inches /76 mm) field guns. The first cannon to contain all 'modern' features is generally considered to be the French 75 of 1897. The gun used cased ammunition, was breech-loading, had modern sights, and a self-contained firing mechanism. It was the first field gun to include a hydro-pneumatic recoil mechanism, which kept the gun's trail and wheels perfectly still during the firing sequence. Since it did not need to be re-aimed after each shot, the crew could fire as soon as the barrel returned to its resting position. In typical use, the French 75 could deliver fifteen rounds per minute on its target, either shrapnel or melinite high-explosive, up to about 5 miles (8,500 m) away. Its firing rate could even reach close to 30 rounds per minute, albeit only for a very short time and with a highly experienced crew. These were rates that contemporary bolt action rifles could not match. Indirect fire Indirect fire, the firing of a projectile without relying on direct line of sight between the gun and the target, possibly dates back to the 16th century. Early battlefield use of indirect fire may have occurred at Paltzig in July 1759, when the Russian artillery fired over the tops of trees, and at the Battle of Waterloo, where a battery of the Royal Horse Artillery fired shrapnel indirectly against advancing French troops. In 1882, Russian Lieutenant Colonel KG Guk published Indirect Fire for Field Artillery, which provided a practical method of using aiming points for indirect fire by describing, "all the essentials of aiming points, crest clearance, and corrections to fire by an observer". A few years later, the Richtfläche (lining-plane) sight was invented in Germany and provided a means of indirect laying in azimuth, complementing the clinometers for indirect laying in elevation which already existed. Despite conservative opposition within the German army, indirect fire was adopted as doctrine by the 1890s. In the early 1900s, Goertz in Germany developed an optical sight for azimuth laying. It quickly replaced the lining-plane; in English, it became the 'Dial Sight' (UK) or 'Panoramic Telescope' (US). The British halfheartedly experimented with indirect fire techniques since the 1890s, but with the onset of the Boer War, they were the first to apply the theory in practice in 1899, although they had to improvise without a lining-plane sight. In the next 15 years leading up to World War I, the techniques of indirect fire became available for all types of artillery. Indirect fire was the defining characteristic of 20th-century artillery and led to undreamt of changes in the amount of artillery, its tactics, organisation, and techniques, most of which occurred during World War I. An implication of indirect fire and improving guns was increasing range between gun and target, this increased the time of flight and the vertex of the trajectory. The result was decreasing accuracy (the increasing distance between the target and the mean point of impact of the shells aimed at it) caused by the increasing effects of non-standard conditions. Indirect firing data was based on standard conditions including a specific muzzle velocity, zero wind, air temperature and density, and propellant temperature. In practice, this standard combination of conditions almost never existed, they varied throughout the day and day to day, and the greater the time of flight, the greater the inaccuracy. An added complication was the need for survey to accurately fix the coordinates of the gun position and provide accurate orientation for the guns. Of course, targets had to be accurately located, but by 1916, air photo interpretation techniques enabled this, and ground survey techniques could sometimes be used. In 1914, the methods of correcting firing data for the actual conditions were often convoluted, and the availability of data about actual conditions was rudimentary or non-existent, the assumption was that fire would always be ranged (adjusted). British heavy artillery worked energetically to progressively solve all these problems from late 1914 onwards, and by early 1918, had effective processes in place for both field and heavy artillery. These processes enabled 'map-shooting', later called 'predicted fire'; it meant that effective fire could be delivered against an accurately located target without ranging. Nevertheless, the mean point of impact was still some tens of yards from the target-centre aiming point. It was not precision fire, but it was good enough for concentrations and barrages. These processes remain in use into the 21st century with refinements to calculations enabled by computers and improved data capture about non-standard conditions. The British major-general Henry Hugh Tudor pioneered armour and artillery cooperation at the breakthrough Battle of Cambrai. The improvements in providing and using data for non-standard conditions (propellant temperature, muzzle velocity, wind, air temperature, and barometric pressure) were developed by the major combatants throughout the war and enabled effective predicted fire. The effectiveness of this was demonstrated by the British in 1917 (at Cambrai) and by Germany the following year (Operation Michael). Major General J.B.A. Bailey, British Army (retired) wrote: An estimated 75,000 French soldiers were casualties of friendly artillery fire in the four years of World War I. Precision-guidance Modern artillery is most obviously distinguished by its long range, firing an explosive shell or rocket and a mobile carriage for firing and transport. However, its most important characteristic is the use of indirect fire, whereby the firing equipment is aimed without seeing the target through its sights. Indirect fire emerged at the beginning of the 20th century and was greatly enhanced by the development of predicted fire methods in World War I. However, indirect fire was area fire; it was and is not suitable for destroying point targets; its primary purpose is area suppression. Nevertheless, by the late 1970s precision-guided munitions started to appear, notably the US 155 mm Copperhead and its Soviet 152 mm Krasnopol equivalent that had success in Indian service. These relied on laser designation to 'illuminate' the target that the shell homed onto. However, in the early 21st century, the Global Positioning System (GPS) enabled relatively cheap and accurate guidance for shells and missiles, notably the US 155 mm Excalibur and the 227 mm GMLRS rocket. The introduction of these led to a new issue, the need for very accurate three dimensional target coordinates—the mensuration process. Weapons covered by the term 'modern artillery' include "cannon" artillery (such as howitzer, mortar, and field gun) and rocket artillery. Certain smaller-caliber mortars are more properly designated small arms rather than artillery, albeit indirect-fire small arms. This term also came to include coastal artillery which traditionally defended coastal areas against seaborne attack and controlled the passage of ships. With the advent of powered flight at the start of the 20th century, artillery also included ground-based anti-aircraft batteries. The term "artillery" has traditionally not been used for projectiles with internal guidance systems, preferring the term "missilery", though some modern artillery units employ surface-to-surface missiles. Advances in terminal guidance systems for small munitions has allowed large-caliber guided projectiles to be developed, blurring this distinction.<ref>{{Cite book|last=Chikammadu|first=Ali Caleb|title=Enotenplato The Chronicle of Military Doctrine'|publisher=Lulu.com|date=September 3, 2019|isbn=9780359806997|pages=196}}</ref> See Long Range Precision Fires (LRPF), Joint terminal attack controllerAmmunition One of the most important roles of logistics is the supply of munitions as a primary type of artillery consumable, their storage (ammunition dump, arsenal, magazine ) and the provision of fuzes, detonators and warheads at the point where artillery troops will assemble the charge, projectile, bomb or shell. A round of artillery ammunition comprises four components: Fuze Projectile Propellant Primer Fuzes Fuzes are the devices that initiate an artillery projectile, either to detonate its High Explosive (HE) filling or eject its cargo (illuminating flare or smoke canisters being examples). The official military spelling is "fuze". Broadly there are four main types: impact (including graze and delay) mechanical time including airburst proximity sensor including airburst programmable electronic detonation including airburst Most artillery fuzes are nose fuzes. However, base fuzes have been used with armor-piercing shells and for squash head (High-Explosive Squash Head (HESH) or High Explosive, Plastic (HEP) anti-tank shells). At least one nuclear shell and its non-nuclear spotting version also used a multi-deck mechanical time fuze fitted into its base. Impact fuzes were, and in some armies remain, the standard fuze for HE projectiles. Their default action is normally 'superquick', some have had a 'graze' action which allows them to penetrate light cover and others have 'delay'. Delay fuzes allow the shell to penetrate the ground before exploding. Armor or Concrete-Piercing (AP or CP) fuzes are specially hardened. During World War I and later, ricochet fire with delay or graze fuzed HE shells, fired with a flat angle of descent, was used to achieve airburst. HE shells can be fitted with other fuzes. Airburst fuzes usually have a combined airburst and impact function. However, until the introduction of proximity fuzes, the airburst function was mostly used with cargo munitions—for example, shrapnel, illumination, and smoke. The larger calibers of anti-aircraft artillery are almost always used airburst. Airburst fuzes have to have the fuze length (running time) set on them. This is done just before firing using either a wrench or a fuze setter pre-set to the required fuze length. Early airburst fuzes used igniferous timers which lasted into the second half of the 20th century. Mechanical time fuzes appeared in the early part of the century. These required a means of powering them. The Thiel mechanism used a spring and escapement (i.e. 'clockwork'), Junghans used centrifugal force and gears, and Dixi used centrifugal force and balls. From about 1980, electronic time fuzes started replacing mechanical ones for use with cargo munitions. Proximity fuzes have been of two types: photo-electric or radar. The former was not very successful and seems only to have been used with British anti-aircraft artillery 'unrotated projectiles' (rockets) in World War II. Radar proximity fuzes were a big improvement over the mechanical (time) fuzes which they replaced. Mechanical time fuzes required an accurate calculation of their running time, which was affected by non-standard conditions. With HE (requiring a burst 20 to above the ground), if this was very slightly wrong the rounds would either hit the ground or burst too high. Accurate running time was less important with cargo munitions that burst much higher. The first radar proximity fuzes (perhaps originally codenamed 'VT' and later called Variable Time (VT)) were invented by the British and developed by the US and initially used against aircraft in World War II. Their ground use was delayed for fear of the enemy recovering 'blinds' (artillery shells which failed to detonate) and copying the fuze. The first proximity fuzes were designed to detonate about above the ground. These air-bursts are much more lethal against personnel than ground bursts because they deliver a greater proportion of useful fragments and deliver them into terrain where a prone soldier would be protected from ground bursts. However, proximity fuzes can suffer premature detonation because of the moisture in heavy rain clouds. This led to 'Controlled Variable Time' (CVT) after World War II. These fuzes have a mechanical timer that switched on the radar about 5 seconds before expected impact, they also detonated on impact. The proximity fuze emerged on the battlefields of Europe in late December 1944. They have become known as the U.S. Artillery's "Christmas present", and were much appreciated when they arrived during the Battle of the Bulge. They were also used to great effect in anti-aircraft projectiles in the Pacific against kamikaze as well as in Britain against V-1 flying bombs. Electronic multi-function fuzes started to appear around 1980. Using solid-state electronics they were relatively cheap and reliable, and became the standard fitted fuze in operational ammunition stocks in some western armies. The early versions were often limited to proximity airburst, albeit with height of burst options, and impact. Some offered a go/no-go functional test through the fuze setter. Later versions introduced induction fuze setting and testing instead of physically placing a fuze setter on the fuze. The latest, such as Junghan's DM84U provide options giving, superquick, delay, a choice of proximity heights of burst, time and a choice of foliage penetration depths. A new type of artillery fuze will appear soon. In addition to other functions these offer some course correction capability, not full precision but sufficient to significantly reduce the dispersion of the shells on the ground. Projectiles The projectile is the munition or "bullet" fired downrange. This may be an explosive device. Projectiles have traditionally been classified as "shot" or "shell", the former being solid and the latter having some form of "payload". Shells can be divided into three configurations: bursting, base ejection or nose ejection. The latter is sometimes called the shrapnel configuration. The most modern is base ejection, which was introduced in World War I. Base and nose ejection are almost always used with airburst fuzes. Bursting shells use various types of fuze depending on the nature of the payload and the tactical need at the time. Payloads have included: Bursting: high-explosive, white phosphorus, coloured marker, chemical, nuclear devices; high-explosive anti-tank and canister may be considered special types of bursting shell. Nose ejection: shrapnel, star, incendiary and flechette (a more modern version of shrapnel). Base ejection: Dual-Purpose Improved Conventional Munition bomblets, which arm themselves and function after a set number of rotations after having been ejected from the projectile (this produces unexploded sub-munitions, or "duds", which remain dangerous), scatterable mines, illuminating, coloured flare, smoke, incendiary, propaganda, chaff (foil to jam radars) and modern exotics such as electronic payloads and sensor-fuzed munitions. Stabilization Rifled: Artillery projectiles have traditionally been spin-stabilised, meaning that they spin in flight so that gyroscopic forces prevent them from tumbling. Spin is induced by gun barrels having rifling, which engages a soft metal band around the projectile, called a "driving band" (UK) or "rotating band" (U.S.). The driving band is usually made of copper, but synthetic materials have been used. Smoothbore/fin-stabilized: In modern artillery, smoothbore barrels have been used mostly by mortars. These projectiles use fins in the airflow at their rear to maintain correct orientation. The primary benefits over rifled barrels is reduced barrel wear, longer ranges that can be achieved (due to the reduced loss of energy to friction and gas escaping around the projectile via the rifling) and larger explosive cores for a given caliber artillery due to less metal needing to be used to form the case of the projectile because of less force applied to the shell from the non-rifled sides of the barrel of smooth bore guns. Rifled/fin-stabilized: A combination of the above can be used, where the barrel is rifled, but the projectile also has deployable fins for stabilization, guidance or gliding. Propellant Most forms of artillery require a propellant to propel the projectile at the target. Propellant is always a low explosive, which means it deflagrates, rather than detonating like high explosives. The shell is accelerated to a high velocity in a very short time by the rapid generation of gas from the burning propellant. This high pressure is achieved by burning the propellant in a contained area, either the chamber of a gun barrel or the combustion chamber of a rocket motor. Until the late 19th century, the only available propellant was black powder. It had many disadvantages as a propellant; it has relatively low power, requiring large amounts of powder to fire projectiles, and created thick clouds of white smoke that would obscure the targets, betray the positions of guns, and make aiming impossible. In 1846, nitrocellulose (also known as guncotton) was discovered, and the high explosive nitroglycerin was discovered at nearly the same time. Nitrocellulose was significantly more powerful than black powder, and was smokeless. Early guncotton was unstable, however, and burned very fast and hot, leading to greatly increased barrel wear. Widespread introduction of smokeless powder would wait until the advent of the double-base powders, which combine nitrocellulose and nitroglycerin to produce powerful, smokeless, stable propellant. Many other formulations were developed in the following decades, generally trying to find the optimum characteristics of a good artillery propellant – low temperature, high energy, non-corrosive, highly stable, cheap, and easy to manufacture in large quantities. Modern gun propellants are broadly divided into three classes: single-base propellants that are mainly or entirely nitrocellulose based, double-base propellants consisting of a combination of nitrocellulose and nitroglycerin, and triple base composed of a combination of nitrocellulose and nitroglycerin and nitroguanidine. Artillery shells fired from a barrel can be assisted to greater range in three ways: Rocket-assisted projectiles enhance and sustain the projectile's velocity by providing additional 'push' from a small rocket motor that is part of the projectile's base. Base bleed uses a small pyrotechnic charge at the base of the projectile to introduce sufficient combustion products into the low-pressure region behind the base of the projectile responsible for a large proportion of the drag. Ramjet-assisted, similar to rocket-assisted, but using a ramjet instead of a rocket motor; it is anticipated that a ramjet-assisted 120-mm mortar shell could reach a range of . Propelling charges for barrel artillery can be provided either as cartridge bags or in metal cartridge cases. Generally, anti-aircraft artillery and smaller-caliber (up to 3" or 76.2 mm) guns use metal cartridge cases that include the round and propellant, similar to a modern rifle cartridge. This simplifies loading and is necessary for very high rates of fire. Bagged propellant allows the amount of powder to be raised or lowered, depending on the range to the target. It also makes handling of larger shells easier. Cases and bags require totally different types of breech. A metal case holds an integral primer to initiate the propellant and provides the gas seal to prevent the gases leaking out of the breech; this is called obturation. With bagged charges, the breech itself provides obturation and holds the primer. In either case, the primer is usually percussion, but electrical is also used, and laser ignition is emerging. Modern 155 mm guns have a primer magazine fitted to their breech. Artillery ammunition has four classifications according to use: Service: ammunition used in live fire training or for wartime use in a combat zone. Also known as "warshot" ammunition. Practice: Ammunition with a non- or minimally-explosive projectile that mimics the characteristics (range, accuracy) of live rounds for use under training conditions. Practice artillery ammunition often utilizes a colored-smoke-generating bursting charge for marking purposes in place of the normal high-explosive charge. Dummy: Ammunition with an inert warhead, inert primer, and no propellant; used for training or display. Blank: Ammunition with live primer, greatly reduced propellant charge (typically black powder), and no projectile; used for training, demonstration or ceremonial use. Field artillery system Because modern field artillery mostly uses indirect fire, the guns have to be part of a system that enables them to attack targets invisible to them, in accordance with the combined arms plan. The main functions in the field artillery system are: Communications Command: authority to allocate resources; Target acquisition: detect, identify and deduce the location of targets; Control: authority to decide which targets to attack and allot fire units to the attack; Computation of firing data – to deliver fire from a fire unit onto its target; Fire units: guns, launchers or mortars grouped together; Specialist services: produce data to support the production of accurate firing data; Logistic services: to provide combat supplies, particularly ammunition, and equipment support. All these calculations to produce a quadrant elevation (or range) and azimuth were done manually using instruments, tabulated, data of the moment, and approximations until battlefield computers started appearing in the 1960s and 1970s. While some early calculators copied the manual method (typically substituting polynomials for tabulated data), computers use a different approach. They simulate a shell's trajectory by 'flying' it in short steps and applying data about the conditions affecting the trajectory at each step. This simulation is repeated until it produces a quadrant elevation and azimuth that lands the shell within the required 'closing' distance of the target coordinates. NATO has a standard ballistic model for computer calculations and has expanded the scope of this into the NATO Armaments Ballistic Kernel (NABK) within the SG2 Shareable (Fire Control) Software Suite (S4). Logistics Supply of artillery ammunition has always been a major component of military logistics. Up until World War I some armies made artillery responsible for all forward ammunition supply because the load of small arms ammunition was trivial compared to artillery. Different armies use different approaches to ammunition supply, which can vary with the nature of operations. Differences include where the logistic service transfers artillery ammunition to artillery, the amount of ammunition carried in units and extent to which stocks are held at unit or battery level. A key difference is whether supply is 'push' or 'pull'. In the former the 'pipeline' keeps pushing ammunition into formations or units at a defined rate. In the latter units fire as tactically necessary and replenish to maintain or reach their authorised holding (which can vary), so the logistic system has to be able to cope with surge and slack. Classification Artillery types can be categorised in several ways, for example by type or size of weapon or ordnance, by role or by organizational arrangements. Types of ordnance The types of cannon artillery are generally distinguished by the velocity at which they fire projectiles. Types of artillery: Cannon: The oldest type of artillery with direct firing trajectory. Bombard: A type of a large calibre, muzzle-loading artillery piece, a cannon or mortar used during sieges to shoot round stone projectiles at the walls of enemy fortifications. Falconet was a type of light cannon developed in the late 15th century that fired a smaller shot than the similar falcon. Swivel gun is a type of small cannon mounted on a swiveling stand or fork which allows a very wide arc of movement. Camel mounted swivel guns called as zamburak were used by the Gunpowder Empires as self-propelled artillery. Siege artillery: Large-caliber artillery that have limited mobility with indirect firing trajectory, which was used to bombard targets at long distances. Large-calibre artillery. Field artillery: Mobile weapons used to support armies in the field. Subcategories include: Infantry support guns: Directly support infantry units. Mountain guns: Lightweight guns that can be disassembled and transported through difficult terrain. Field guns: Capable of long-range direct fires. Howitzers: Capable of high-angle fire, they are most often employed for indirect-fire. Gun-howitzers: Capable of high or low-angle fire with a longer barrel. Mortars: Typically muzzle-loaded, short-barreled, high-trajectory weapons designed primarily for an indirect-fire role. Gun-mortars: Typically breech-loaded, capable of high or low-angle fire with a longer barrel. Tank guns: Large-caliber guns mounted on tanks to provide mobile direct fire. Anti-tank artillery: Guns, usually mobile, designed primarily for direct fire to destroy armored fighting vehicles with heavy armor. Anti-tank gun: Guns designed for direct fire to destroy tanks and other armored fighting vehicles. Anti-aircraft artillery: Guns, usually mobile, designed for attacking aircraft by land and/or at sea. Some guns were suitable for the dual roles of anti-aircraft and anti-tank warfare. Rocket artillery: Launches rockets or missiles, instead of shot or shell. Railway gun: Large-caliber weapons that are mounted on, transported by and fired from specially-designed railway wagons. Naval artillery: Guns mounted on warships to be used either against other naval vessels or to bombard coastal targets in support of ground forces. The crowning achievement of naval artillery was the battleship, but the advent of air power and missiles have rendered this type of artillery largely obsolete. They are typically longer-barreled, low-trajectory, high-velocity weapons designed primarily for a direct-fire role. Coastal artillery: Fixed-position weapons dedicated to defense of a particular location, usually a coast (for example, the Atlantic Wall in World War II) or harbor. Not needing to be mobile, coastal artillery used to be much larger than equivalent field artillery pieces, giving them longer range and more destructive power. Modern coastal artillery (for example, Russia's "Bereg" system) is often self-propelled, (allowing it to avoid counter-battery fire) and fully integrated, meaning that each battery has all of the support systems that it requires (maintenance, targeting radar, etc.) organic to its unit. Aircraft artillery: Large-caliber guns mounted on attack aircraft, this is typically found on slow-flying gunships. Nuclear artillery: Artillery which fires nuclear shells. Modern field artillery can also be split into two other subcategories: towed and self-propelled. As the name suggests, towed artillery has a prime mover, usually an artillery tractor or truck, to move the piece, crew, and ammunition around. Towed artillery is in some cases equipped with an APU for small displacements. Self-propelled artillery is permanently mounted on a carriage or vehicle with room for the crew and ammunition and is thus capable of moving quickly from one firing position to another, both to support the fluid nature of modern combat and to avoid counter-battery fire. It includes mortar carrier vehicles, many of which allow the mortar to be removed from the vehicle and be used dismounted, potentially in terrain in which the vehicle cannot navigate, or in order to avoid detection. Organizational types At the beginning of the modern artillery period, the late 19th century, many armies had three main types of artillery, in some case they were sub-branches within the artillery branch in others they were separate branches or corps. There were also other types excluding the armament fitted to warships: Horse artillery, first formed as regular units in the late 18th century, with the role of supporting cavalry, they were distinguished by the entire crew being mounted. Field or "foot" artillery, the main artillery arm of the field army, using either guns, howitzers, or mortars. In World War II this branch again started using rockets and later surface to surface missiles. Fortress or garrison artillery, operated a nation's fixed defences using guns, howitzers or mortars, either on land or coastal frontiers. Some had deployable elements to provide heavy artillery to the field army. In some nations coast defence artillery was a naval responsibility. Mountain artillery, a few nations treated mountain artillery as a separate branch, in others it was a speciality in another artillery branch. They used light guns or howitzers, usually designed for pack animal transport and easily broken down into small easily handled loads Naval artillery, some nations carried pack artillery on some warships, these were used and manhandled by naval (or marine) landing parties. At times, part of a ship's armament would be unshipped and mated to makeshift carriages and limbers for actions ashore, for example during the Second Boer War, during the First World War the guns from the stricken SMS Königsberg formed the main artillery strength of the German forces in East Africa. After World War I many nations merged these different artillery branches, in some cases keeping some as sub-branches. Naval artillery disappeared apart from that belonging to marines. However, two new branches of artillery emerged during that war and its aftermath, both used specialised guns (and a few rockets) and used direct not indirect fire, in the 1950s and 1960s both started to make extensive use of missiles: Anti-tank artillery, also under various organisational arrangements but typically either field artillery or a specialist branch and additional elements integral to infantry, etc., units. However, in most armies field and anti-aircraft artillery also had at least a secondary anti-tank role. After World War II anti-tank in Western armies became mostly the responsibility of infantry and armoured branches and ceased to be an artillery matter, with some exceptions. Anti-aircraft artillery, under various organisational arrangements including being part of artillery, a separate corps, even a separate service or being split between army for the field and air force for home defence. In some cases infantry and the new armoured corps also operated their own integral light anti-aircraft artillery. Home defence anti-aircraft artillery often used fixed as well as mobile mountings. Some anti-aircraft guns could also be used as field or anti-tank artillery, providing they had suitable sights. However, the general switch by artillery to indirect fire before and during World War I led to a reaction in some armies. The result was accompanying or infantry guns. These were usually small, short range guns, that could be easily man-handled and used mostly for direct fire but some could use indirect fire. Some were operated by the artillery branch but under command of the supported unit. In World War II they were joined by self-propelled assault guns, although other armies adopted infantry or close support tanks in armoured branch units for the same purpose, subsequently tanks generally took on the accompanying role. Equipment types The three main types of artillery "gun" are guns, howitzers, and mortars. During the 20th century, guns and howitzers have steadily merged in artillery use, making a distinction between the terms somewhat meaningless. By the end of the 20th century, true guns with calibers larger than about 60 mm have become very rare in artillery use, the main users being tanks, ships, and a few residual anti-aircraft and coastal guns. The term "cannon" is a United States generic term that includes guns, howitzers, and mortars; it is not used in other English speaking armies. The traditional definitions differentiated between guns and howitzers in terms of maximum elevation (well less than 45° as opposed to close to or greater than 45°), number of charges (one or more than one charge), and having higher or lower muzzle velocity, sometimes indicated by barrel length. These three criteria give eight possible combinations, of which guns and howitzers are but two. However, modern "howitzers" have higher velocities and longer barrels than the equivalent "guns" of the first half of the 20th century. True guns are characterized by long range, having a maximum elevation significantly less than 45°, a high muzzle velocity and hence a relatively long barrel, smooth bore (no rifling) and a single charge. The latter often led to fixed ammunition where the projectile is locked to the cartridge case. There is no generally accepted minimum muzzle velocity or barrel length associated with a gun. Howitzers can fire at maximum elevations at least close to 45°; elevations up to about 70° are normal for modern howitzers. Howitzers also have a choice of charges, meaning that the same elevation angle of fire will achieve a different range depending on the charge used. They have rifled bores, lower muzzle velocities and shorter barrels than equivalent guns. All this means they can deliver fire with a steep angle of descent. Because of their multi-charge capability, their ammunition is mostly separate loading (the projectile and propellant are loaded separately). That leaves six combinations of the three criteria, some of which have been termed gun howitzers. A term first used in the 1930s when howitzers with a relatively high maximum muzzle velocities were introduced, it never became widely accepted, most armies electing to widen the definition of "gun" or "howitzer". By the 1960s, most equipment had maximum elevations up to about 70°, were multi-charge, had quite high maximum muzzle velocities and relatively long barrels. Mortars are simpler. The modern mortar originated in World War I and there were several patterns. After that war, most mortars settled on the Stokes pattern, characterized by a short barrel, smooth bore, low muzzle velocity, elevation angle of firing generally greater than 45°, and a very simple and light mounting using a "baseplate" on the ground. The projectile with its integral propelling charge was dropped down the barrel from the muzzle to hit a fixed firing pin. Since that time, a few mortars have become rifled and adopted breech loading. There are other recognized typifying characteristics for artillery. One such characteristic is the type of obturation used to seal the chamber and prevent gases escaping through the breech. This may use a metal cartridge case that also holds the propelling charge, a configuration called "QF" or "quickfiring" by some nations. The alternative does not use a metal cartridge case, the propellant being merely bagged or in combustible cases with the breech itself providing all the sealing. This is called "BL" or "breech loading" by some nations. A second characteristic is the form of propulsion. Modern equipment can either be towed or self-propelled (SP). A towed gun fires from the ground and any inherent protection is limited to a gun shield. Towing by horse teams lasted throughout World War II in some armies, but others were fully mechanized with wheeled or tracked gun towing vehicles by the outbreak of that war. The size of a towing vehicle depends on the weight of the equipment and the amount of ammunition it has to carry. A variation of towed is portee, where the vehicle carries the gun which is dismounted for firing. Mortars are often carried this way. A mortar is sometimes carried in an armored vehicle and can either fire from it or be dismounted to fire from the ground. Since the early 1960s it has been possible to carry lighter towed guns and most mortars by helicopter. Even before that, they were parachuted or landed by glider from the time of the first airborne trials in the USSR in the 1930s. In SP equipment, the gun is an integral part of the vehicle that carries it. SPs first appeared during World War I, but did not really develop until World War II. They are mostly tracked vehicles, but wheeled SPs started to appear in the 1970s. Some SPs have no armor and carry few or no other weapons and ammunition. Armored SPs usually carry a useful ammunition load. Early armored SPs were mostly a "casemate" configuration, in essence an open top armored box offering only limited traverse. However, most modern armored SPs have a full enclosed armored turret, usually giving full traverse for the gun. Many SPs cannot fire without deploying stabilizers or spades, sometimes hydraulic. A few SPs are designed so that the recoil forces of the gun are transferred directly onto the ground through a baseplate. A few towed guns have been given limited self-propulsion by means of an auxiliary engine. Two other forms of tactical propulsion were used in the first half of the 20th century: Railways or transporting the equipment by road, as two or three separate loads, with disassembly and re-assembly at the beginning and end of the journey. Railway artillery took two forms, railway mountings for heavy and super-heavy guns and howitzers and armored trains as "fighting vehicles" armed with light artillery in a direct fire role. Disassembled transport was also used with heavy and super heavy weapons and lasted into the 1950s. Caliber categories A third form of artillery typing is to classify it as "light", "medium", "heavy" and various other terms. It appears to have been introduced in World War I, which spawned a very wide array of artillery in all sorts of sizes so a simple categorical system was needed. Some armies defined these categories by bands of calibers. Different bands were used for different types of weapons—field guns, mortars, anti-aircraft guns and coastal guns. Modern operations List of countries in order of amount of artillery (only conventional barrel ordnance is given, in use with land forces): Artillery is used in a variety of roles depending on its type and caliber. The general role of artillery is to provide fire support—"the application of fire, coordinated with the manoeuvre of forces to destroy, neutralize or suppress the enemy". This NATO definition makes artillery a supporting arm although not all NATO armies agree with this logic. The italicised terms are NATO's. Unlike rockets, guns (or howitzers as some armies still call them) and mortars are suitable for delivering close supporting fire. However, they are all suitable for providing deep supporting fire although the limited range of many mortars tends to exclude them from the role. Their control arrangements and limited range also mean that mortars are most suited to direct supporting fire. Guns are used either for this or general supporting fire while rockets are mostly used for the latter. However, lighter rockets may be used for direct fire support. These rules of thumb apply to NATO armies. Modern mortars, because of their lighter weight and simpler, more transportable design, are usually an integral part of infantry and, in some armies, armor units. This means they generally do not have to concentrate their fire so their shorter range is not a disadvantage. Some armies also consider infantry operated mortars to be more responsive than artillery, but this is a function of the control arrangements and not the case in all armies. However, mortars have always been used by artillery units and remain with them in many armies, including a few in NATO. In NATO armies artillery is usually assigned a tactical mission that establishes its relationship and responsibilities to the formation or units it is assigned to. It seems that not all NATO nations use the terms and outside NATO others are probably used. The standard terms are: direct support, general support, general support reinforcing and reinforcing. These tactical missions are in the context of the command authority: operational command, operational control, tactical command or tactical control. In NATO direct support generally means that the directly supporting artillery unit provides observers and liaison to the manoeuvre troops being supported, typically an artillery battalion or equivalent is assigned to a brigade and its batteries to the brigade's battalions. However, some armies achieve this by placing the assigned artillery units under command of the directly supported formation. Nevertheless, the batteries' fire can be concentrated onto a single target, as can the fire of units in range and with the other tactical missions. Application of fire There are several dimensions to this subject. The first is the notion that fire may be against an opportunity target or may be arranged. If it is the latter it may be either on-call or scheduled. Arranged targets may be part of a fire plan. Fire may be either observed or unobserved, if the former it may be adjusted, if the latter then it has to be predicted. Observation of adjusted fire may be directly by a forward observer or indirectly via some other target acquisition system. NATO also recognises several different types of fire support for tactical purposes: Counterbattery fire: delivered for the purpose of destroying or neutralizing the enemy's fire support system. Counterpreparation fire: intensive prearranged fire delivered when the imminence of the enemy attack is discovered. Covering fire: used to protect troops when they are within range of enemy small arms. Defensive fire: delivered by supporting units to assist and protect a unit engaged in a defensive action. Final Protective Fire: an immediately available prearranged barrier of fire designed to impede enemy movement across defensive lines or areas. Harassing fire: a random number of shells are fired at random intervals, without any pattern to it that the enemy can predict. This process is designed to hinder enemy forces' movement, and, by the constantly imposed stress, threat of losses and inability of enemy forces to relax or sleep, lowers their morale. Interdiction fire: placed on an area or point to prevent the enemy from using the area or point. Preparation fire: delivered before an attack to weaken the enemy position. These purposes have existed for most of the 20th century, although their definitions have evolved and will continue to do so, lack of suppression in counterbattery is an omission. Broadly they can be defined as either: Deep supporting fire: directed at objectives not in the immediate vicinity of own force, for neutralizing or destroying enemy reserves and weapons, and interfering with enemy command, supply, communications and observation; or Close supporting fire: placed on enemy troops, weapons or positions which, because of their proximity present the most immediate and serious threat to the supported unit. Two other NATO terms also need definition: Neutralization fire: delivered to render a target temporarily ineffective or unusable; and Suppression fire: that degrades the performance of a target below the level needed to fulfill its mission. Suppression is usually only effective for the duration of the fire. The tactical purposes also include various "mission verbs", a rapidly expanding subject with the modern concept of "effects based operations".Targeting is the process of selecting target and matching the appropriate response to them taking account of operational requirements and capabilities. It requires consideration of the type of fire support required and the extent of coordination with the supported arm. It involves decisions about: what effects are required, for example, neutralization or suppression; the proximity of and risks to own troops or non-combatants; what types of munitions, including their fuzing, are to be used and in what quantities; when the targets should be attacked and possibly for how long; what methods should be used, for example, converged or distributed, whether adjustment is permissible or surprise essential, the need for special procedures such as precision or danger close how many fire units are needed and which ones they should be from those that are available (in range, with the required munitions type and quantity, not allotted to another target, have the most suitable line of fire if there is a risk to own troops or non-combatants); The targeting process is the key aspect of tactical fire control. Depending on the circumstances and national procedures it may all be undertaken in one place or may be distributed. In armies practicing control from the front, most of the process may be undertaken by a forward observer or other target acquirer. This is particularly the case for a smaller target requiring only a few fire units. The extent to which the process is formal or informal and makes use of computer based systems, documented norms or experience and judgement also varies widely armies and other circumstances. Surprise may be essential or irrelevant. It depends on what effects are required and whether or not the target is likely to move or quickly improve its protective posture. During World War II UK researchers concluded that for impact fuzed munitions the relative risk were as follows: men standing – 1 men lying – 1/3 men firing from trenches – 1/15–1/50 men crouching in trenches – 1/25–1/100 Airburst munitions significantly increase the relative risk for lying men, etc. Historically most casualties occur in the first 10–15 seconds of fire, i.e. the time needed to react and improve protective posture, however, this is less relevant if airburst is used. There are several ways of making best use of this brief window of maximum vulnerability: ordering the guns to fire together, either by executive order or by a "fire at" time. The disadvantage is that if the fire is concentrated from many dispersed fire units then there will be different times of flight and the first rounds will be spread in time. To some extent a large concentration offsets the problem because it may mean that only one round is required from each gun and most of these could arrive in the 15 second window. burst fire, a rate of fire to deliver three rounds from each gun within 10 or 15 seconds, this reduces the number of guns and hence fire units needed, which means they may be less dispersed and have less variation in their times of flight. Smaller caliber guns, such as 105 mm, have always been able to deliver three rounds in 15 seconds, larger calibers firing fixed rounds could also do it but it was not until the 1970s that a multi-charge 155 mm howitzer, FH-70 first gained the capability. multiple round simultaneous impact (MRSI), where a single weapon or multiple individual weapons fire multiple rounds at differing trajectories so that all rounds arrive on target at the same time. time on target'', fire units fire at the time less their time of flight, this works well with prearranged scheduled fire but is less satisfactory for opportunity targets because it means delaying the delivery of fire by selecting a 'safe' time that all or most fire units can achieve. It can be used with both the previous two methods. Counter-battery fire Modern counter-battery fire developed in World War I, with the objective of defeating the enemy's artillery. Typically such fire was used to suppress enemy batteries when they were or were about to interfere with the activities of friendly forces (such as to prevent enemy defensive artillery fire against an impending attack) or to systematically destroy enemy guns. In World War I the latter required air observation. The first indirect counter-battery fire was in May 1900 by an observer in a balloon. Enemy artillery can be detected in two ways, either by direct observation of the guns from the air or by ground observers (including specialist reconnaissance), or from their firing signatures. This includes radars tracking the shells in flight to determine their place of origin, sound ranging detecting guns firing and resecting their position from pairs of microphones or cross-observation of gun flashes using observation by human observers or opto-electronic devices, although the widespread adoption of 'flashless' propellant limited the effectiveness of the latter. Once hostile batteries have been detected they may be engaged immediately by friendly artillery or later at an optimum time, depending on the tactical situation and the counter-battery policy. Air strike is another option. In some situations the task is to locate all active enemy batteries for attack using a counter-battery fire at the appropriate moment in accordance with a plan developed by artillery intelligence staff. In other situations counter-battery fire may occur whenever a battery is located with sufficient accuracy. Modern counter-battery target acquisition uses unmanned aircraft, counter-battery radar, ground reconnaissance and sound-ranging. Counter-battery fire may be adjusted by some of the systems, for example the operator of an unmanned aircraft can 'follow' a battery if it moves. Defensive measures by batteries include frequently changing position or constructing defensive earthworks, the tunnels used by North Korea being an extreme example. Counter-measures include air defence against aircraft and attacking counter-battery radars physically and electronically. Field artillery team 'Field Artillery Team' is a US term and the following description and terminology applies to the US, other armies are broadly similar but differ in significant details. Modern field artillery (post–World War I) has three distinct parts: the Forward Observer (FO), the Fire Direction Center (FDC) and the actual guns themselves. The forward observer observes the target using tools such as binoculars, laser rangefinders, designators and call back fire missions on his radio, or relays the data through a portable computer via an encrypted digital radio connection protected from jamming by computerized frequency hopping. A lesser known part of the team is the FAS or Field Artillery Survey team which sets up the "Gun Line" for the cannons. Today most artillery battalions use a(n) "Aiming Circle" which allows for faster setup and more mobility. FAS teams are still used for checks and balances purposes and if a gun battery has issues with the "Aiming Circle" a FAS team will do it for them. The FO can communicate directly with the battery FDC, of which there is one per each battery of 4–8 guns. Otherwise the several FOs communicate with a higher FDC such as at a Battalion level, and the higher FDC prioritizes the targets and allocates fires to individual batteries as needed to engage the targets that are spotted by the FOs or to perform preplanned fires. The Battery FDC computes firing data—ammunition to be used, powder charge, fuse settings, the direction to the target, and the quadrant elevation to be fired at to reach the target, what gun will fire any rounds needed for adjusting on the target, and the number of rounds to be fired on the target by each gun once the target has been accurately located—to the guns. Traditionally this data is relayed via radio or wire communications as a warning order to the guns, followed by orders specifying the type of ammunition and fuse setting, direction, and the elevation needed to reach the target, and the method of adjustment or orders for fire for effect (FFE). However, in more advanced artillery units, this data is relayed through a digital radio link. Other parts of the field artillery team include meteorological analysis to determine the temperature, humidity and pressure of the air and wind direction and speed at different altitudes. Also radar is used both for determining the location of enemy artillery and mortar batteries and to determine the precise actual strike points of rounds fired by battery and comparing that location with what was expected to compute a registration allowing future rounds to be fired with much greater accuracy. Time on target A technique called time on target (TOT) was developed by the British Army in North Africa at the end of 1941 and early 1942 particularly for counter-battery fire and other concentrations, it proved very popular. It relied on BBC time signals to enable officers to synchronize their watches to the second because this avoided the need to use military radio networks and the possibility of losing surprise, and the need for field telephone networks in the desert. With this technique the time of flight from each fire unit (battery or troop) to the target is taken from the range or firing tables, or the computer and each engaging fire unit subtracts its time of flight from the TOT to determine the time to fire. An executive order to fire is given to all guns in the fire unit at the correct moment to fire. When each fire unit fires their rounds at their individual firing time all the opening rounds will reach the target area almost simultaneously. This is especially effective when combined with techniques that allow fires for effect to be made without preliminary adjusting fires. Multiple round simultaneous impact Multiple round simultaneous impact (MRSI) is a modern version of the earlier time on target concept. MRSI is when a single gun fires multiple shells so all arrive at the same target simultaneously. This is possible because there is more than one trajectory for a round to fly to any given target. Typically one is below 45 degrees from horizontal and the other is above it, and by using different sized propellant charges with each shell, it is possible to utilize more than two trajectories. Because the higher trajectories cause the shells to arc higher into the air, they take longer to reach the target. If shells are fired on higher trajectories for initial volleys (starting with the shell with the most propellant and working down) and later volleys are fired on the lower trajectories, with the correct timing the shells will all arrive at the same target simultaneously. This is useful because many more shells can land on the target with no warning. With traditional methods of firing, the target area may have time (however long it takes to reload and re-fire the guns) to take cover between volleys. However, guns capable of burst fire can deliver multiple rounds in a few seconds if they use the same firing data for each, and if guns in more than one location are firing on one target they can use Time on Target procedures so that all their shells arrive at the same time and target. MRSI has a few prerequisites. The first is guns with a high rate of fire. The second is the ability to use different sized propellant charges. Third is a fire control computer that has the ability to compute MRSI volleys and the capability to produce firing data, sent to each gun, and then presented to the gun commander in the correct order. The number of rounds that can be delivered in MRSI depends primarily on the range to the target and the rate of fire. To allow the most shells to reach the target, the target has to be in range of the lowest propellant charge. Examples of guns with a rate of fire that makes them suitable for MRSI includes UK's AS-90, South Africa's Denel G6-52 (which can land six rounds simultaneously at targets at least away), Germany's Panzerhaubitze 2000 (which can land five rounds simultaneously at targets at least away), Slovakia's 155 mm SpGH ZUZANA model 2000, and K9 Thunder. The Archer project (developed by BAE-Systems Bofors in Sweden) is a 155 mm howitzer on a wheeled chassis which is claimed to be able to deliver up to six shells on target simultaneously from the same gun. The 120 mm twin barrel AMOS mortar system, joint developed by Hägglunds (Sweden) and Patria (Finland), is capable of 7 + 7 shells MRSI. The United States Crusader program (now cancelled) was slated to have MRSI capability. It is unclear how many fire control computers have the necessary capabilities. Two-round MRSI firings were a popular artillery demonstration in the 1960s, where well trained detachments could show off their skills for spectators. Air burst The destructiveness of artillery bombardments can be enhanced when some or all of the shells are set for airburst, meaning that they explode in the air above the target instead of upon impact. This can be accomplished either through time fuzes or proximity fuzes. Time fuzes use a precise timer to detonate the shell after a preset delay. This technique is tricky and slight variations in the functioning of the fuze can cause it to explode too high and be ineffective, or to strike the ground instead of exploding above it. Since December 1944 (Battle of the Bulge), proximity fuzed artillery shells have been available that take the guesswork out of this process. These employ a miniature, low powered radar transmitter in the fuze to detect the ground and explode them at a predetermined height above it. The return of the weak radar signal completes an electrical circuit in the fuze which explodes the shell. The proximity fuze itself was developed by the British to increase the effectiveness of anti-aircraft warfare. This is a very effective tactic against infantry and light vehicles, because it scatters the fragmentation of the shell over a larger area and prevents it from being blocked by terrain or entrenchments that do not include some form of robust overhead cover. Combined with TOT or MRSI tactics that give no warning of the incoming rounds, these rounds are especially devastating because many enemy soldiers are likely to be caught in the open; even more so if the attack is launched against an assembly area or troops moving in the open rather than a unit in an entrenched tactical position. Use in monuments Numerous war memorials around the world incorporate an artillery piece that was used in the war or battle commemorated.

() () is a large public square and transport hub in the central Mitte district of Berlin. The square is named after the Russian Tsar Alexander I, which also denotes the larger neighbourhood stretching from in the north-east to and the in the south-west. is reputedly the most visited area of Berlin, beating Friedrichstrasse and City West. It is a popular starting point for tourists, with many attractions including the (TV tower), the Nikolai Quarter and the ('Red City Hall') situated nearby. is still one of Berlin's major commercial areas, housing various shopping malls, department stores and other large retail locations. History Early history to the 18th century A hospital stood at the location of present-day since the 13th century. Named (St. George), the hospital gave its name to the nearby (George Gate) of the Berlin city wall. Outside the city walls, this area was largely undeveloped until around 1400, when the first settlers began building thatched cottages. As a gallows was located close by, the area earned the nickname the ('Devil's Pleasure Garden'). The George Gate became the most important of Berlin's city gates during the 16th century, being the main entry point for goods arriving along the roads to the north and north-east of the city, for example from , and , and the big Hanseatic cities on the Baltic Sea. After the Thirty Years' War, the city wall was strengthened. From 1658 to 1683, a citywide fortress was constructed to plans by the Linz master builder, . The new fortress contained 13 bastions connected by ramparts and was preceded by a moat measuring up to wide. Within the new fortress, many of the historic city wall gates were closed. For example, the southeastern Gate was closed but the Georgian Gate remained open, making the Georgian Gate an even more important entrance to the city. In 1681, the trade of cattle and pig fattening was banned within the city. Frederick William, the Great Elector, granted cheaper plots of land, waiving the basic interest rate, in the area in front of the Georgian Gate. Settlements grew rapidly and a weekly cattle market was established on the square in front of the Gate. The area developed into a suburb – the – which continued to flourish into the late 17th century. Unlike the southwestern suburbs (, ) which were strictly and geometrically planned, the suburbs in the northeast (, and the ) proliferated without plan. Despite a building ban imposed in 1691, more than 600 houses existed in the area by 1700. At that time, the George Gate was a rectangular gatehouse with a tower. Next to the tower stood a remaining tower from the original medieval city walls. The upper floors of the gatehouse served as the city jail. A drawbridge spanned the moat and the gate was locked at nightfall by the garrison using heavy oak planks. A highway ran through the cattle market to the northeast towards . To the right stood the George chapel, an orphanage and a hospital that was donated by the Elector Sophie Dorothea in 1672. Next to the chapel stood a dilapidated medieval plague house which was demolished in 1716. Behind it was a rifleman's field and an inn, later named the . By the end of the 17th century, 600 to 700 families lived in this area. They included butchers, cattle herders, shepherds and dairy farmers. The George chapel was upgraded to the George church and received its own preacher. (1701–1805) After his coronation in on 6 May 1701 the Prussian King Frederick I entered Berlin through the George Gate. This led to the gate being renamed the King's Gate, and the surrounding area became known in official documents as (King's Gate Square). The suburb was renamed (or 'royal suburbs' short). In 1734, the Berlin Customs Wall, which initially consisted of a ring of palisade fences, was reinforced and grew to encompass the old city and its suburbs, including . This resulted in the King's Gate losing importance as an entry point for goods into the city. The gate was finally demolished in 1746. By the end of the 18th century, the basic structure of the royal suburbs of the had been developed. It consisted of irregular-shaped blocks of buildings running along the historic highways which once carried goods in various directions out of the gate. At this time, the area contained large factories (silk and wool), such as the (one of Berlin's first cloth factories, located in a former barn) and a workhouse established in 1758 for beggars and homeless people, where the inmates worked a man-powered treadmill to turn a mill. Soon, military facilities came to dominate the area, such as the 1799–1800 military parade grounds designed by David Gilly. At this time, the residents of the were mostly craftsmen, petty-bourgeois, retired soldiers and manufacturing workers. The southern part of the later was separated from traffic by trees and served as a parade ground, whereas the northern half remained a market. Beginning in the mid-18th century, the most important wool market in Germany was held in . Between 1752 and 1755, the writer lived in a house on Alexanderplatz. In 1771, a new stone bridge (the ) was built over the moat and in 1777 a colonnade-lined row of shops () was constructed by architect . Between 1783 and 1784, seven three-storey buildings were erected around the square by , including the famous , where lived as a permanent tenant and stayed in the days before his suicide. (1805–1900) On 25 October 1805 the Russian Tsar Alexander I was welcomed to the city on the parade grounds in front of the old King's Gate. To mark this occasion, on 2 November, King Frederick William III ordered the square to be renamed : In the southeast of the square, the cloth factory buildings were converted into the Theater by at a cost of 120,000 Taler. The foundation stone was laid on 31 August 1823 and the opening ceremony occurred on 4 August 1824. Sales were poor, forcing the theatre to close on 3 June 1851. Thereafter, the building was used for wool storage, then as a tenement building, and finally as an inn called until the building's demolition in 1932. During these years, was populated by fish wives, water carriers, sand sellers, rag-and-bone men, knife sharpeners and day laborers. Because of its importance as a transport hub, horse-drawn buses ran every 15 minutes between and in 1847. During the March Revolution of 1848, large-scale street fighting occurred on the streets of , where revolutionaries used barricades to block the route from to the city. Novelist and poet , who worked in the vicinity in a nearby pharmacy, participated in the construction of barricades and later described how he used materials from the Theater to barricade . The continued to grow throughout the 19th century, with three-storey developments already existing at the beginning of the century and fourth storeys being constructed from the middle of the century. By the end of the century, most of the buildings were already five storeys high. The large factories and military facilities gave way to housing developments (mainly rental housing for the factory workers who had just moved into the city) and trading houses. At the beginning of the 1870s, the Berlin administration had the former moat filled to build the Berlin city railway, which was opened in 1882 along with (' Railway Station'). In 1883–1884, the Grand Hotel, a neo-Renaissance building with 185 rooms and shops beneath was constructed. From 1886 to 1890, built the police headquarters, a huge brick building whose tower on the northern corner dominated the building. In 1890, a district court at was also established. In 1886, the local authorities built a central market hall west of the rail tracks, which replaced the weekly market on the in 1896. During the end of the 19th century, the emerging private traffic and the first horse bus lines dominated the northern part of the square, the southern part (the former parade ground) remained quiet, having green space elements added by garden director in 1889. The northwest of the square contained a second, smaller green space where, in 1895, the copper Berolina statue by sculptor was erected. Between Empire and the Nazi era (1900–1940) At the beginning of the 20th century, experienced its heyday. In 1901, founded the first German cabaret, the , in the former ('Secession stage') at , initially under the name . It was announced as " as upscale entertainment with artistic ambitions. Emperor-loyal and market-oriented stands the uncritical amusement in the foreground." The merchants , and opened large department stores on : (1904–1911), (1910–1911) and (1911). marketed itself as a department store for the Berlin people, whereas modelled itself as a department store for the world. In October 1905, the first section of the department store opened to the public. It was designed by architects and , who had already won second prize in the competition for the construction of the building. The department store underwent further construction phases and, in 1911, had a commercial space of and the longest department store façade in the world at in length. For the construction of the department store, by architects and , the were removed in 1910 and now stand in the Park in . In October 1908, the ('house of teachers') was opened next to the at . It was designed by and Henry Gross. The building belonged to the ('teachers’ association'), who rented space on the ground floor of the building out to a pastry shop and restaurant to raise funds for the association. The building housed the teachers' library which survived two world wars, and today is integrated into the library for educational historical research. The rear of the property contained the association's administrative building, a hotel for members and an exhibition hall. Notable events that took place in the hall include the funeral services for and on 2 February 1919 and, on 4 December 1920, the (Unification Party Congress) of the Communist Party and the USPD. The First Ordinary Congress of the Communist Workers Party of Germany was held in the nearby restaurant, 1–4 August 1920. 's position as a main transport and traffic hub continued to fuel its development. In addition to the three underground lines, long-distance trains and trains ran along the 's viaduct arches. Omnibuses, horse-drawn from 1877 and, after 1898, also electric-powered trams, ran out of in all directions in a star shape. The subway station was designed by Alfred Grenander and followed the colour-coded order of subway stations, which began with green at and ran through to dark red. In the Golden Twenties, was the epitome of the lively, pulsating cosmopolitan city of Berlin, rivalled in the city only by . Many of the buildings and rail bridges surrounding the platz bore large billboards that illuminated the night. The Berlin cigarette company Manoli had a famous billboard at the time which contained a ring of neon tubes that constantly circled a black ball. The proverbial "" of those years was characterized as "". Writer wrote a poem referencing the advert, and the composer Rudolf Nelson made the legendary with the dancer Lucie Berber. The writer named his novel, , after the square, and filmed parts of his 1927 film (Berlin: The Symphony of the Big City) at . Destruction of (1940–1945) One of Berlin's largest air-raid shelters during the Second World War was situated under . It was built between 1941 and 1943 for the by . The war reached in early April 1945. The Berolina statue had already been removed in 1944 and probably melted down for use in arms production. During the Battle of Berlin, Red Army artillery bombarded the area around . The battles of the last days of the war destroyed considerable parts of the historic , as well as many of the buildings around . The had entrenched itself within the tunnels of the underground system. Hours before fighting ended in Berlin on 2 May 1945, troops of the SS detonated explosives inside the north–south tunnel under the Canal to slow the advance of the Red Army towards Berlin's city centre. The entire tunnel flooded, as well as large sections of the network via connecting passages at the underground station. Many of those seeking shelter in the tunnels were killed. Of the then of subway tunnel, around were flooded with more than one million cubic meters () of water. Demolition and reconstruction (1945–1964) Before a planned reconstruction of the entire could take place, all the war ruins needed to be demolished and cleared away. A popular black market emerged within the ruined area, which the police raided several times a day. One structure demolished after World War II was the 'Rote Burg', a red brick building with round arches, previously used as police and Gestapo headquarters. The huge construction project began in 1886 and was completed in 1890; it was one of Berlin's largest buildings. The 'castle' suffered extensive damage during 1944-45 and was demolished in 1957. The site on the southwest corner of Alexanderplatz remained largely unused as a carpark until the Alexa shopping centre opened in 2007. Reconstruction planning for post-war Berlin gave priority to the dedicated space to accommodate the rapidly growing motor traffic in inner-city thoroughfares. This idea of a traffic-orientated city was already based on considerations and plans by and from the 1930s. East Germany has been subject to redevelopment several times in its history, most recently during the 1960s, when it was turned into a pedestrian zone and enlarged as part of the German Democratic Republic's redevelopment of the city centre. It is surrounded by several notable structures including the (TV Tower). During the Peaceful Revolution of 1989, the demonstration on 4 November 1989 was the largest demonstration in the history of the German Democratic Republic. Protests starting 15 October and peaked on 4 November with an estimated 200,000 participants who called on the government of the ruling Socialist Unity Party of Germany to step down and demanded a free press, the opening of the borders and their right to travel. Speakers were , , , , , and . The protests continued and culminated in the unexpected Fall of the Berlin Wall on 9 November 1989. After German reunification (1989) Ever since German reunification, has undergone a gradual process of change with many of the surrounding buildings being renovated. After the political turnaround in the wake of the fall of the Berlin Wall, socialist urban planning and architecture of the 1970s no longer corresponded to the current ideas of an inner-city square. Investors demanded planning security for their construction projects. After initial discussions with the public, the goal quickly arose to reinstate 's tram network for better connections to surrounding city quarters. In 1993, an urban planning ideas competition for architects took place to redesign the square and its surrounding area. In the first phase, there were 16 submissions, five of which were selected for the second phase of the competition. These five architects had to adapt their plans to detailed requirements. For example, the return of the Alex's trams was planned, with the implementation to be made in several stages. The winner, who was determined on 17 September 1993, was the Berlin architect . 's plan was based on Behrens’ design, provided a horseshoe-shaped area of seven- to eight-storey buildings and high towers with 42 floors. The and the – both listed buildings – would form the southwestern boundary. Second place went to the design by and . The proposal of the architecture firm Kny & Weber, which was strongly based on the horseshoe shape of Wagner, finally won the third place. The design by was chosen on 7 June 1994 by the Berlin Senate as a basis for the further transformation of . In 1993, architect 's master plan for a major redevelopment including the construction of several skyscrapers was published. In 1995, completed the renovation of the . In 1998, the first tram returned to , and in 1999, the town planning contracts for the implementation of and 's plans were signed by the landowners and the investors. 21st century On 2 April 2000, the Senate finally fixed the development plan for . The purchase contracts between investors and the Senate Department for Urban Development were signed on 23 May 2002, thus laying the foundations for the development. The CUBIX multiplex cinema (CineStar Cubix am Alexanderplatz, styled CUBIX), which opened in November 2000, joined the team of Berlin International Film Festival cinemas in 2007, and the festival shows films on three of its screens. Renovation of the department store began in 2004, led by Berlin professor of architecture, and his son . The building was enlarged by about and has since operated under the name . Beginning with the reconstruction of the department store in 2004, and the biggest underground railway station of Berlin, some buildings were redesigned and new structures built on the square's south-eastern side. Sidewalks were expanded to shrink one of the avenues, a new underground garage was built, and commuter tunnels meant to keep pedestrians off the streets were removed. Between 2005 and 2006, was renovated and later became a branch of the clothing chain, C&A. In 2005, the began work to extend the tram line from to (Alex II). This route was originally to be opened in 2000 but was postponed several times. After further delays caused by the 2006 FIFA World Cup, the route opened on 30 May 2007. In February 2006, the redesign of the walk-in plaza began. The redevelopment plans were provided by the architecture firm Gerkan, Marg and Partners and the Hamburg-based company . The final plans emerged from a design competition launched by the state of Berlin in 2004. However, the paving work was temporarily interrupted a few months after the start of construction by the 2006 FIFA World Cup and all excavation pits had to be provisionally asphalted over. The construction work could only be completed at the end of 2007. The renovation of , the largest Berlin underground station, had been ongoing since the mid-1990s and was finally completed in October 2008. The was given a pavement of yellow granite, bordered by grey mosaic paving around the buildings. Wall AG modernized the 1920s-era underground toilets at a cost of 750,000 euros. The total redesign cost amounted to around 8.7 million euros. On 12 September 2007 the Alexa shopping centre opened. It is located in the immediate vicinity of the , on the site of the old Berlin police headquarters. With a sales area, it is one of the largest shopping centres in Berlin. In May 2007, the Texas property development company Hines began building a six-story commercial building named . The building was built on a plot of , which, according to the plans, closes the square to the east and thus reduces the area of the Platz. The building was opened on 25 March 2009. At the beginning of 2007, the construction company created an underground garage with three levels below the , located between the hotel tower and the building, which cost 25 million euros to build and provides space for around 700 cars. The opening took place on 26 November 2010. At the same time, the Senate narrowed from almost wide to wide (), thus reducing it to three lanes in each direction. Behind the station, next to the CUBIX cinema in the immediate vicinity of the TV tower, the high residential and commercial building, Alea 101, was built between 2012 and 2014. As of 2014 it as assessed that due to a lack of demand the skyscrapers planned in 1993 were unlikely to be constructed. In January 2014, a 39-story residential tower designed by Frank Gehry was announced, but this project was put on hold in 2018. The area is the largest area for crime in Berlin. As of October 2017, was classified a ("crime-contaminated location") by the (General Safety and Planning Laws). Today and future plans Despite the reconstruction of the tram line crossing, it has retained its socialist character, including the much-graffitied , a popular venue. is reputedly the most visited area of Berlin, beating Friedrichstrasse and City West. It is a popular starting point for tourists, with many attractions including the (TV tower), the Nikolai Quarter and the ('Red City Hall') situated nearby. is still one of Berlin's major commercial areas, housing various shopping malls, department stores and other large retail locations. Many historic buildings are located in the vicinity of . The traditional seat of city government, the , or 'Red City Hall', is located nearby, as was the former East German parliament building, the . The was demolished from 2006–2008 to make room for a full reconstruction of the Baroque Berlin Palace, or , which is set to open in 2019. is also the name of the S-Bahn and U-Bahn stations there. It is one of Berlin's largest and most important transportation hubs, being a meeting place of three subway () lines, three lines, and many tram and bus lines, as well as regional trains. It also accommodates the Park Inn Berlin and the World Time Clock, a continually rotating installation that shows the time throughout the globe, the House of Travel, and 's (House of Teachers)'. Long-term plans exist for the demolition of the high former (now the Hotel Park-Inn), with the site to be replaced by three skyscrapers. If and when this plan will be implemented is unclear, especially since the hotel tower received a new façade as recently as in 2005, and the occupancy rates of the hotel are very good. However, the plans could give way in the next few years to a suggested high new block conversion. The previous main tenant of the development, Saturn, moved into the building in March 2009. In 2014, Primark opened a branch inside the hotel building. The majority of the planned high skyscrapers will probably never be built. The state of Berlin has announced that it will not enforce the corresponding urban development contracts against the market. Of the 13 planned skyscrapers, 10 remained as of 2008, after modifications to the plans – eight of which had construction rights. Some investors in the Alexa shopping centre announced several times since 2007 that they would sell their respective shares in the plot to an investor interested in building a high-rise building. The first concrete plans for the construction of a high-rise were made by Hines, the investor behind die mitte. In 2009, the construction of a high tower to be built behind die mitte was announced. On 12 September 2011, a slightly modified development plan was presented, which provided for a residential tower housing 400 apartments. In early 2013, the development plan was opened to the public. In autumn 2015, the Berlin Senate organized two forums in which interested citizens could express their opinions on the proposed changes to the . Architects, city planners and Senate officials held open discussions. On that occasion, however, it was reiterated that the plans for high-rise developments were not up for debate. According to the master plan of the architect , up to eleven huge buildings will continue to be built, which will house a mixture of shops and apartments. At the beginning of March 2018, it was announced that the district office had granted planning permission for the first residential high-rise in , the high Alexander Tower. On 29 of the 35 floors, 377 apartments are to be built. It would be located next to the Alexa shopping centre, with a planned completion date of 2021.

The Asian Development Bank (ADB) is a regional development bank established on 19 December 1966, which is headquartered in 6 ADB Avenue, Mandaluyong, Metro Manila 1550, Philippines. The bank also maintains 31 field offices around the world to promote social and economic development in Asia. The bank admits the members of the UN Economic and Social Commission for Asia and the Pacific (UNESCAP, formerly the Economic Commission for Asia and the Far East or ECAFE), and non-regional developed countries. Starting with 31 members at its establishment, ADB now has 68 members. The ADB was modeled closely on the World Bank and has a similar weighted voting system, where votes are distributed in proportion with members' capital subscriptions. ADB releases an annual report that summarizes its operations, budget, and other materials for review by the public. The ADB-Japan Scholarship Program (ADB-JSP) enrolls about 300 students annually in academic institutions located in 10 countries within the Region. After completing their study programs, scholars are expected to contribute to the economic and social development of their home countries. ADB holds the status of an official United Nations Observer. As of 31 December 2020, Japan and the United States each holds the largest proportion of shares at 15.571%. China holds 6.429%, India holds 6.317%, and Australia holds 5.773%. Organization The highest policy-making body of the bank is the Board of Governors, composed of one representative from each member state. The Board of Governors, in turn, elect among themselves the twelve members of the board of directors and their deputies. Eight of the twelve members come from regional (Asia-Pacific) members while the others come from non-regional members. The Board of Governors also elect the bank's president, who is the chairperson of the board of directors and manages ADB. The president has a term of office lasting five years, and may be re-elected. Traditionally, and because Japan is one of the largest shareholders of the bank, the president has always been Japanese. The current president is Masatsugu Asakawa. He succeeded Takehiko Nakao on 17 January 2020, who succeeded Haruhiko Kuroda in 2013. The headquarters of the bank is at 6 ADB Avenue, Mandaluyong, Metro Manila, Philippines, and it has 42 field offices in Asia and the Pacific and representative offices in Washington, Frankfurt, Tokyo and Sydney. The bank employs about 3,000 people, representing 60 of its 68 members. List of presidents (*) As from 17 January 2020, Masatsugu Asakawa was president of ADB. History 1960s As early as 1956, Japan Finance Minister Hisato Ichimada had suggested to United States Secretary of State John Foster Dulles that development projects in Southeast Asia could be supported by a new financial institution for the region. A year later, Japanese Prime Minister Nobusuke Kishi announced that Japan intended to sponsor the establishment of a regional development fund with resources largely from Japan and other industrial countries. But the US did not warm to the plan and the concept was shelved. See full account in "Banking the Future of Asia and the Pacific: 50 Years of the Asian Development Bank," July 2017. The idea came up again late in 1962 when Kaoru Ohashi, an economist from a research institute in Tokyo, visited Takeshi Watanabe, then a private financial consultant in Tokyo, and proposed a study group to form a development bank for the Asian region. The group met regularly in 1963, examining various scenarios for setting up a new institution and drew on Watanabe's experiences with the World Bank. However, the idea received a cool reception from the World Bank itself and the study group became discouraged. In parallel, the concept was formally proposed at a trade conference organized by the Economic Commission for Asia and the Far East (ECAFE) in 1963 by a young Thai economist, Paul Sithi-Amnuai. (ESCAP, United Nations Publication March 2007, "The first parliament of Asia" pp. 65). Despite an initial mixed reaction, support for the establishment of a new bank soon grew. An expert group was convened to study the idea, with Japan invited to contribute to the group. When Watanabe was recommended, the two streams proposing a new bank—from ECAFE and Japan—came together. Initially, the US was on the fence, not opposing the idea but not ready to commit financial support. But a new bank for Asia was soon seen to fit in with a broader program of assistance to Asia planned by United States President Lyndon B. Johnson in the wake of the escalating U.S. military support for the government of South Vietnam. As a key player in the concept, Japan hoped that the ADB offices would be in Tokyo. However, eight other cities had also expressed an interest: Bangkok, Colombo, Kabul, Kuala Lumpur, Manila, Phnom Penh, Singapore, and Tehran. To decide, the 18 prospective regional members of the new bank held three rounds of votes at a ministerial conference in Manila in November/December 1965. In the first round on 30 November, Tokyo failed to win a majority, so a second ballot was held the next day at noon. Although Japan was in the lead, it was still inconclusive, so a final vote was held after lunch. In the third poll, Tokyo gained eight votes to Manila's nine, with one abstention. Therefore, Manila was declared the host of the new development bank; the Japanese were mystified and deeply disappointed. Watanabe later wrote in his personal history of ADB: "I felt as if the child I had so carefully reared had been taken away to a distant country." (Asian Development Bank publication, "Towards a New Asia", 1977, p. 16) As intensive work took place during 1966 to prepare for the opening of the new bank in Manila, high on the agenda was choice of president. Japanese Prime Minister Eisaku Satō asked Watanabe to be a candidate. Although he initially declined, pressure came from other countries and Watanabe agreed. In the absence of any other candidates, Watanabe was elected first President of the Asian Development Bank at its Inaugural Meeting on 24 November 1966. By the end of 1972, Japan had contributed $173.7 million (22.6% of the total) to the ordinary capital resources and $122.6 million (59.6% of the total) to the special funds. In contrast, the United States contributed only $1.25 million to the special fund. After its creation in the 1960s, ADB focused much of its assistance on food production and rural development. At the time, Asia was one of the poorest regions in the world. Early loans went largely to Indonesia, Thailand, Malaysia, South Korea and the Philippines; these countries accounted for 78.48% of the total ADB loans between 1967 and 1972. Moreover, Japan received tangible benefits, 41.67% of the total procurements between 1967 and 1976. Japan tied its special funds contributions to its preferred sectors and regions and procurements of its goods and services, as reflected in its $100 million donation for the Agricultural Special Fund in April 1968. Watanabe served as the first ADB president to 1972. 1970s–1980s In the 1970s, ADB's assistance to developing countries in Asia expanded into education and health, and then to infrastructure and industry. The gradual emergence of Asian economies in the latter part of the decade spurred demand for better infrastructure to support economic growth. ADB focused on improving roads and providing electricity. When the world suffered its first oil price shock, ADB shifted more of its assistance to support energy projects, especially those promoting the development of domestic energy sources in member countries. Following considerable pressure from the Reagan Administration in the 1980s, ADB reluctantly began working with the private sector in an attempt to increase the impact of its development assistance to poor countries in Asia and the Pacific. In the wake of the second oil crisis, ADB expanded its assistance to energy projects. In 1982, ADB opened its first field office, in Bangladesh, and later in the decade, it expanded its work with non-government organizations (NGOs). Japanese presidents Inoue Shiro (1972–76) and Yoshida Taroichi (1976–81) took the spotlight in the 1970s. Fujioka Masao, the fourth president (1981–90), adopted an assertive leadership style, launching an ambitious plan to expand the ADB into a high-impact development agency. On November 18, 1972, the Bank inaugurated its headquarters along Roxas Boulevard in Pasay City, Philippines. In the early 1990s, ADB moved its offices to Ortigas Center in Pasig City, with the Department of Foreign Affairs (Philippines) taking over its old Pasay premises. 1990s In the 1990s, ADB began promoting regional cooperation by helping the countries on the Mekong River to trade and work together. The decade also saw an expansion of ADB's membership with the addition of several Central Asian countries following the end of the Cold War. In mid-1997, ADB responded to the financial crisis that hit the region with projects designed to strengthen financial sectors and create social safety nets for the poor. During the crisis, ADB approved its largest single loan – a $4 billion emergency loan to South Korea. In 1999, ADB adopted poverty reduction as its overarching goal. 2000s The early 2000s saw a dramatic expansion of private sector finance. While the institution had such operations since the 1980s (under pressure from the Reagan Administration) the early attempts were highly unsuccessful with low lending volumes, considerable losses and financial scandals associated with an entity named AFIC. However, beginning in 2002, the ADB undertook a dramatic expansion of private sector lending under a new team. Over the course of the next six years, the Private Sector Operations Department (PSOD) grew by a factor of 41 times the 2001 levels of new financings and earnings for the ADB. This culminated with the Board's formal recognition of these achievements in March 2008, when the Board of Directors formally adopted the Long Term Strategic Framework (LTSF). That document formally stated that assistance to private sector development was the lead priority of the ADB and that it should constitute 50% of the bank's lending by 2020. In 2003, the severe acute respiratory syndrome (SARS) epidemic hit the region and ADB responded with programs to help the countries in the region work together to address infectious diseases, including avian influenza and HIV/AIDS. ADB also responded to a multitude of natural disasters in the region, committing more than $850 million for recovery in areas of India, Indonesia, Maldives, and Sri Lanka which were impacted by the 2004 Indian Ocean earthquake and tsunami. In addition, $1 billion in loans and grants was provided to the victims of the October 2005 earthquake in Pakistan. In December 2005, China donated $20 million to the ADB for a regional poverty alleviation fund; China's first such fund set up at an international institution. In 2009, ADB's Board of Governors agreed to triple ADB's capital base from $55 billion to $165 billion, giving it much-needed resources to respond to the global economic crisis. The 200% increase is the largest in ADB's history, and was the first since 1994. 2010s Asia moved beyond the economic crisis and by 2010 had emerged as a new engine of global economic growth though it remained home to two-thirds of the world's poor. In addition, the increasing prosperity of many people in the region created a widening income gap that left many people behind. ADB responded to this with loans and grants that encouraged economic growth. In early 2012, the ADB began to re-engage with Myanmar in response to reforms initiated by the government. In April 2014, ADB opened an office in Myanmar and resumed making loans and grants to the country. In 2017, ADB combined the lending operations of its Asian Development Fund (ADF) with its ordinary capital resources (OCR). The result was to expand the OCR balance sheet to permit increasing annual lending and grants to $20 billion by 2020 — 50% more than the previous level. In 2020, ADB gave a $2 million grant from the Asia Pacific Disaster Response Fund, to support the Armenian government in the fight against the spread of COVID-19 pandemic. In the same year, the ADB committed a $20 million loan to Electric Networks of Armenia, that will ensure electricity for the citizens during the pandemic, as well as approved $500,000 in regional technical assistance to procure personal protective equipment and other medical supplies. Objectives and activities Aim The ADB defines itself as a social development organization that is dedicated to reducing poverty in Asia and the Pacific through inclusive economic growth, environmentally sustainable growth, and regional integration. This is carried out through investments – in the form of loans, grants and information sharing – in infrastructure, health care services, financial and public administration systems, helping countries prepare for the impact of climate change or better manage their natural resources, as well as other areas. Focus areas Eighty percent of ADB's lending is concentrated public sector lending in five operational areas. Education – Most developing countries in Asia and the Pacific have earned high marks for a dramatic rise in primary education enrollment rates in the last three decades, but daunting challenges remain, threatening economic and social growth. Environment, Climate Change, and Disaster Risk Management – Environmental sustainability is a prerequisite for economic growth and poverty reduction in Asia and the Pacific. Finance Sector Development – The financial system is the lifeline of a country's economy. It creates prosperity that can be shared throughout society and benefit the poorest and most vulnerable people. Financial sector and capital market development, including microfinance, small and medium-sized enterprises, and regulatory reforms, is vital to decreasing poverty in Asia and the Pacific. This has been a key priority of the Private Sector Operations Department (PSOD) since 2002. One of the most active sub-sectors of finance is the PSOD's support for trade finance. Each year the PSOD finances billions of dollars in letters of credit across all of Asia and the rest of the world. Infrastructure, including transport and communications, energy, water supply and sanitation, and urban development. Regional Cooperation and Integration – Regional cooperation and integration (RCI) was introduced by President Kuroda when he joined the ADB in 2004. It was seen as a long-standing priority of the Japanese government as a process by which national economies become more regionally connected. It plays a critical role in accelerating economic growth, reducing poverty and economic disparity, raising productivity and employment, and strengthening institutions. Private Sector Lending – This priority was introduced into the ADB's activities at the insistence of the Reagan Administration. However, that effort was never a true priority until the administration of President Tadeo Chino who in turn brought in a seasoned American banker – Robert Bestani. From then on, the Private Sector Operations Department (PSOD) grew at a very rapid pace, growing from the smallest financing unit of the ADB to the largest in terms of financing volume. As noted earlier, this culminated in the Long Term Strategic Framework (LTSF) which was adopted by the Board in March 2008. Financings The ADB offers "hard" loans on commercial terms primarily to middle income countries in Asia and "soft" loans with lower interest rates to poorer countries in the region. Based on a new policy, both types of loans will be sourced starting January 2017 from the bank's ordinary capital resources (OCR), which functions as its general operational fund. The ADB's Private Sector Department (PSOD) can and does offer a broader range of financings beyond commercial loans. They also have the capability to provide guarantees, equity and mezzanine finance (a combination of debt and equity). In 2017, ADB lent $19.1 billion of which $3.2 billion went to private enterprises, as part of its "non-sovereign" operations. ADB's operations in 2017, including grants and co-financing, totaled $28.9 billion. ADB obtains its funding by issuing bonds on the world's capital markets. It also relies on the contributions of member countries, retained earnings from lending operations, and the repayment of loans. Private sector investments ADB provides direct financial assistance, in the form of debt, equity and mezzanine finance to private sector companies, for projects that have clear social benefits beyond the financial rate of return. ADB's participation is usually limited but it leverages a large amount of funds from commercial sources to finance these projects by holding no more than 25% of any given transaction. Co-financing ADB partners with other development organizations on some projects to increase the amount of funding available. In 2014, $9.2 billion—or nearly half—of ADB's $22.9 billion in operations were financed by other organizations. According to Jason Rush, Principal Communication Specialist, the Bank communicates with many other multilateral organizations. Funds and resources More than 50 financing partnership facilities, trust funds, and other funds – totaling several billion each year – are administered by ADB and put toward projects that promote social and economic development in Asia and the Pacific. ADB has raised Rupees 5 billion or around Rupees 500 crores from its issuance of 5-year offshore Indian rupee (INR) linked bonds. On 26 Feb 2020, ADB raises $118 million from rupee-linked bonds and supporting the development of India International Exchange in India, as it also contributes to an established yield curve which stretches from 2021 through 2030 with $1 billion of outstanding bonds. Access to information ADB has an information disclosure policy that presumes all information that is produced by the institution should be disclosed to the public unless there is a specific reason to keep it confidential. The policy calls for accountability and transparency in operations and the timely response to requests for information and documents. ADB does not disclose information that jeopardizes personal privacy, safety and security, certain financial and commercial information, as well as other exceptions.

Oxfam Australia has criticized the Asian Development Bank for insensitivity to local communities. "Operating at a global and international level, these banks can undermine people's human rights through projects that have detrimental outcomes for poor and marginalized communities." The bank also received criticism from the United Nations Environmental Program, stating in a report that "much of the growth has bypassed more than 70 percent of its rural population, many of whom are directly dependent on natural resources for livelihoods and incomes." There had been criticism that ADB's large scale projects cause social and environmental damage due to lack of oversight. One of the most controversial ADB-related projects is Thailand's Mae Moh coal-fired power station. Environmental and human rights activists say ADB's environmental safeguards policy as well as policies for indigenous peoples and involuntary resettlement, while usually up to international standards on paper, are often ignored in practice, are too vague or weak to be effective, or are simply not enforced by bank officials. The bank has been criticized over its role and relevance in the food crisis. The ADB has been accused by civil society of ignoring warnings leading up the crisis and also contributing to it by pushing loan conditions that many say unfairly pressure governments to deregulate and privatize agriculture, leading to problems such as the rice supply shortage in Southeast Asia. Indeed, whereas the Private Sector Operations Department (PSOD) closed out that year with financings of $2.4 billion, the ADB has significantly dropped below that level in the years since and is clearly not on the path to achieving its stated goal of 50% of financings to the private sector by 2020. Critics also point out that the PSOD is the only Department that actually makes money for the ADB. Hence, with the vast majority of loans going to concessionary (sub-market) loans to the public sector, the ADB is facing considerable financial difficulty and continuous operating losses. Countries with the largest subscribed capital and voting rights The following table are amounts for 20 largest countries by subscribed capital and voting power at the Asian Development Bank as of December 2021. Members ADB has 68 members (as of 23 March 2019): 49 members from the Asian and Pacific Region, and 19 members from Other Regions. The year listed after a member's name indicates the year of their membership. When a country no longer remains a member, the Bank shall arrange for the repurchase of such country's shares by the Bank as a part of the settlement of accounts with such country in accordance with the provisions of paragraphs 3 and 4 of Article 43.

The Airbus A300 is Airbus' first production aircraft and the world's first twin-engine, double-aisle (wide-body) airliner, developed and manufactured by Airbus from 1971–2007. In September 1967, aircraft manufacturers in the United Kingdom, France, and West Germany signed an initial memorandum of understanding to collaborate to develop an innovative large airliner. West Germany and France reached a firm agreement on 29 May 1969, after the British withdrew from the project on 10 April 1969. The pan-European collaborative aerospace manufacturer Airbus Industrie was formally created on 18 December 1970 to develop and produce it. The A300 prototype first flew on 28 October 1972. The first twin-engine widebody airliner, the A300 typically seats 247 passengers in two classes over a range of 5,375 to 7,500 km (2,900 to 4,050 nmi; ). Initial variants are powered by General Electric CF6-50 or Pratt & Whitney JT9D turbofans and have a three-crew flight deck. The improved A300-600 has a two-crew cockpit and updated CF6-80C2 or PW4000 engines; it made its first flight on 8 July 1983 and entered service later that year. The A300 is the basis of the smaller A310 (first flown in 1982) and was adapted in a freighter version. Its cross section was retained for the larger four-engined A340 (1991) and the larger twin-engined A330 (1992). It is also the basis for the oversize Beluga transport (1994). Unlike most Airbus products, it has a yoke, not using a fly-by-wire system. Launch customer Air France introduced the type on 23 May 1974. After limited demand initially, sales took off as the type was proven in early service, beginning three decades of steady orders. It has a similar capacity to the Boeing 767-300, introduced in 1986, but lacked the 767-300ER range. During the 1990s, the A300 became popular with cargo aircraft operators, as both passenger airliner conversions and as original builds. Production ceased in July 2007 after 561 deliveries. , there are 197 A300 family aircraft still in commercial service. Development Origins During the 1960s, European aircraft manufacturers such as Hawker Siddeley and the British Aircraft Corporation, based in the UK, and Sud Aviation of France, had ambitions to build a new 200-seat airliner for the growing civil aviation market. While studies were performed and considered, such as a stretched twin-engine variant of the Hawker Siddeley Trident and an expanded development of the British Aircraft Corporation (BAC) One-Eleven, designated the BAC Two-Eleven, it was recognized that if each of the European manufacturers were to launch similar aircraft into the market at the same time, neither would achieve sales volume needed to make them viable. In 1965, a British government study, known as the Plowden Report, had found British aircraft production costs to be between 10% and 20% higher than American counterparts due to shorter production runs, which was in part due to the fractured European market. To overcome this factor, the report recommended the pursuit of multinational collaborative projects between the region's leading aircraft manufacturers. European manufacturers were keen to explore prospective programmes; the proposed 260-seat wide-body HBN 100 between Hawker Siddeley, Nord Aviation, and Breguet Aviation being one such example. National governments were also keen to support such efforts amid a belief that American manufacturers could dominate the European Economic Community; in particular, Germany had ambitions for a multinational airliner project to invigorate its aircraft industry, which had declined considerably following the Second World War. During the mid-1960s, both Air France and American Airlines had expressed interest in a short-haul twin-engine wide-body aircraft, indicating a market demand for such an aircraft to be produced. In July 1967, during a high-profile meeting between French, German, and British ministers, an agreement was made for greater cooperation between European nations in the field of aviation technology, and "for the joint development and production of an airbus". The word airbus at this point was a generic aviation term for a larger commercial aircraft, and was considered acceptable in multiple languages, including French. Shortly after the July 1967 meeting, French engineer Roger Béteille was appointed as the technical director of what would become the A300 programme, while Henri Ziegler, chief operating office of Sud Aviation, was appointed as the general manager of the organisation and German politician Franz Josef Strauss became the chairman of the supervisory board. Béteille drew up an initial work share plan for the project, under which French firms would produce the aircraft's cockpit, the control systems, and lower-centre portion of the fuselage, Hawker Siddeley would manufacture the wings, while German companies would produce the forward, rear and upper part of the center fuselage sections. Additional work included moving elements of the wings being produced in the Netherlands, and Spain producing the horizontal tail plane. An early design goal for the A300 that Béteille had stressed the importance of was the incorporation of a high level of technology, which would serve as a decisive advantage over prospective competitors. As such, the A300 would feature the first use of composite materials of any passenger aircraft, the leading and trailing edges of the tail fin being composed of glass fibre reinforced plastic. Béteille opted for English as the working language for the developing aircraft, as well against using Metric instrumentation and measurements, as most airlines already had US-built aircraft. These decisions were partially influenced by feedback from various airlines, such as Air France and Lufthansa, as an emphasis had been placed on determining the specifics of what kind of aircraft that potential operators were seeking. According to Airbus, this cultural approach to market research had been crucial to the company's long-term success. Workshare and redefinition On 26 September 1967, the British, French, and West German governments signed a Memorandum of Understanding to start development of the 300-seat Airbus A300. At this point, the A300 was only the second major joint aircraft programme in Europe, the first being the Anglo-French Concorde. Under the terms of the memorandum, Britain and France were each to receive a 37.5 per cent work share on the project, while Germany received a 25 per cent share. Sud Aviation was recognized as the lead company for A300, with Hawker Siddeley being selected as the British partner company. At the time, the news of the announcement had been clouded by the British Government's support for the Airbus, which coincided with its refusal to back BAC's proposed competitor, the BAC 2–11, despite a preference for the latter expressed by British European Airways (BEA). Another parameter was the requirement for a new engine to be developed by Rolls-Royce to power the proposed airliner; a derivative of the in-development Rolls-Royce RB211, the triple-spool RB207, capable of producing of . The programme cost was US$4.6 billion (in 1993 Dollars). In December 1968, the French and British partner companies (Sud Aviation and Hawker Siddeley) proposed a revised configuration, the 250-seat Airbus A250. It had been feared that the original 300-seat proposal was too large for the market, thus it had been scaled down to produce the A250. The dimensional changes involved in the shrink reduced the length of the fuselage by and the diameter by , reducing the overall weight by . For increased flexibility, the cabin floor was raised so that standard LD3 freight containers could be accommodated side-by-side, allowing more cargo to be carried. Refinements made by Hawker Siddeley to the wing's design provided for greater lift and overall performance; this gave the aircraft the ability to climb faster and attain a level cruising altitude sooner than any other passenger aircraft. It was later renamed the A300B. Perhaps the most significant change of the A300B was that it would not require new engines to be developed, being of a suitable size to be powered by Rolls-Royce's RB211, or alternatively the American Pratt & Whitney JT9D and General Electric CF6 powerplants; this switch was recognized as considerably reducing the project's development costs. To attract potential customers in the US market, it was decided that General Electric CF6-50 engines would power the A300 in place of the British RB207; these engines would be produced in co-operation with French firm Snecma. By this time, Rolls-Royce had been concentrating their efforts upon developing their RB211 turbofan engine instead and progress on the RB207's development had been slow for some time, the firm having suffered due to funding limitations, both of which had been factors in the engine switch decision. On 10 April 1969, a few months after the decision to drop the RB207 had been announced, the British government announced that they would withdraw from the Airbus venture. In response, West Germany proposed to France that they would be willing to contribute up to 50% of the project's costs if France was prepared to do the same. Additionally, the managing director of Hawker Siddeley, Sir Arnold Alexander Hall, decided that his company would remain in the project as a favoured sub-contractor, developing and manufacturing the wings for the A300, which would later become pivotal in later versions' impressive performance from short domestic to long intercontinental flights. Hawker Siddeley spent £35 million of its own funds, along with a further £35 million loan from the West German government, on the machine tooling to design and produce the wings. Programme launch On 29 May 1969, during the Paris Air Show, French transport minister Jean Chamant and German economics minister Karl Schiller signed an agreement officially launching the Airbus A300, the world's first twin-engine widebody airliner. The intention of the project was to produce an aircraft that was smaller, lighter, and more economical than its three-engine American rivals, the McDonnell Douglas DC-10 and the Lockheed L-1011 TriStar. In order to meet Air France's demands for an aircraft larger than 250-seat A300B, it was decided to stretch the fuselage to create a new variant, designated as the A300B2, which would be offered alongside the original 250-seat A300B, henceforth referred to as the A300B1. On 3 September 1970, Air France signed a letter of intent for six A300s, marking the first order to be won for the new airliner. In the aftermath of the Paris Air Show agreement, it was decided that, in order to provide effective management of responsibilities, a Groupement d'intérêt économique would be established, allowing the various partners to work together on the project while remaining separate business entities. On 18 December 1970, Airbus Industrie was formally established following an agreement between Aérospatiale (the newly merged Sud Aviation and Nord Aviation) of France and the antecedents to Deutsche Aerospace of Germany, each receiving a 50 per cent stake in the newly formed company. In 1971, the consortium was joined by a third full partner, the Spanish firm CASA, who received a 4.2 per cent stake, the other two members reducing their stakes to 47.9 per cent each. In 1979, Britain joined the Airbus consortium via British Aerospace, which Hawker Siddeley had merged into, which acquired a 20 per cent stake in Airbus Industrie with France and Germany each reducing their stakes to 37.9 per cent. Prototype and flight testing Airbus Industrie was initially headquartered in Paris, which is where design, development, flight testing, sales, marketing, and customer support activities were centred; the headquarters was relocated to Toulouse in January 1974. The final assembly line for the A300 was located adjacent to Toulouse Blagnac International Airport. The manufacturing process necessitated transporting each aircraft section being produced by the partner companies scattered across Europe to this one location. The combined use of ferries and roads were used for the assembly of the first A300, however this was time-consuming and not viewed as ideal by Felix Kracht, Airbus Industrie's production director. Kracht's solution was to have the various A300 sections brought to Toulouse by a fleet of Boeing 377-derived Aero Spacelines Super Guppy aircraft, by which means none of the manufacturing sites were more than two hours away. Having the sections airlifted in this manner made the A300 the first airliner to use just-in-time manufacturing techniques, and allowed each company to manufacture its sections as fully equipped, ready-to-fly assemblies. In September 1969, construction of the first prototype A300 began. On 28 September 1972, this first prototype was unveiled to the public, it conducted its maiden flight from Toulouse–Blagnac International Airport on 28 October that year. This maiden flight, which was performed a month ahead of schedule, lasted for one hour and 25 minutes; the captain was Max Fischl and the first officer was Bernard Ziegler, son of Henri Ziegler. In 1972, unit cost was US$17.5M. On 5 February 1973, the second prototype performed its maiden flight. The flight test programme, which involved a total of four aircraft, was relatively problem-free, accumulating 1,580 flight hours throughout. In September 1973, as part of promotional efforts for the A300, the new aircraft was taken on a six-week tour around North America and South America, to demonstrate it to airline executives, pilots, and would-be customers. Amongst the consequences of this expedition, it had allegedly brought the A300 to the attention of Frank Borman of Eastern Airlines, one of the "big four" U.S. airlines. Entry into service On 15 March 1974, type certificates were granted for the A300 from both German and French authorities, clearing the way for its entry into revenue service. On 23 May 1974, Federal Aviation Administration (FAA) certification was received. The first production model, the A300B2, entered service in 1974, followed by the A300B4 one year later. Initially, the success of the consortium was poor, in part due to the economic consequences of the 1973 oil crisis, but by 1979 there were 81 A300 passenger liners in service with 14 airlines, alongside 133 firm orders and 88 options. Ten years after the official launch of the A300, the company had achieved a 26 per cent market share in terms of dollar value, enabling Airbus Industries to proceed with the development of its second aircraft, the Airbus A310. Design The Airbus A300 is a wide-body medium-to-long range airliner; it has the distinction of being the first twin-engine wide-body aircraft in the world. In 1977, the A300 became the first Extended Range Twin Operations (ETOPS)-compliant aircraft, due to its high performance and safety standards. Another world-first of the A300 is the use of composite materials on a commercial aircraft, which were used on both secondary and later primary airframe structures, decreasing overall weight and improving cost-effectiveness. Other firsts included the pioneering use of centre-of-gravity control, achieved by transferring fuel between various locations across the aircraft, and electrically signalled secondary flight controls. The A300 is powered by a pair of underwing turbofan engines, either General Electric CF6 or Pratt & Whitney JT9D engines; the sole use of underwing engine pods allowed for any suitable turbofan engine to be more readily used. The lack of a third tail-mounted engine, as per the trijet configuration used by some competing airliners, allowed for the wings to be located further forwards and to reduce the size of the vertical stabiliser and elevator, which had the effect of increasing the aircraft's flight performance and fuel efficiency. Airbus partners had employed the latest technology, some of which having been derived from Concorde, on the A300. According to Airbus, new technologies adopted for the airliner were selected principally for increased safety, operational capability, and profitability. Upon entry into service in 1974, the A300 was a very advanced plane, which went on to influence later airliner designs. The technological highlights include advanced wings by de Havilland (later BAE Systems) with supercritical airfoil sections for economical performance and advanced aerodynamically efficient flight control surfaces. The diameter circular fuselage section allows an eight-abreast passenger seating and is wide enough for 2 LD3 cargo containers side by side. Structures are made from metal billets, reducing weight. It is the first airliner to be fitted with wind shear protection. Its advanced autopilots are capable of flying the aircraft from climb-out to landing, and it has an electrically controlled braking system. Later A300s incorporated other advanced features such as the Forward-Facing Crew Cockpit (FFCC), which enabled a two-pilot flight crew to fly the aircraft alone without the need for a flight engineer, the functions of which were automated; this two-man cockpit concept was a world-first for a wide-body aircraft. Glass cockpit flight instrumentation, which used cathode ray tube (CRT) monitors to display flight, navigation, and warning information, along with fully digital dual autopilots and digital flight control computers for controlling the spoilers, flaps, and leading-edge slats, were also adopted upon later-built models. Additional composites were also made use of, such as carbon-fibre-reinforced polymer (CFRP), as well as their presence in an increasing proportion of the aircraft's components, including the spoilers, rudder, air brakes, and landing gear doors. Another feature of later aircraft was the addition of wingtip fences, which improved aerodynamic performance and thus reduced cruise fuel consumption by about 1.5% for the A300-600. In addition to passenger duties, the A300 became widely used by air freight operators; according to Airbus, it is the best-selling freight aircraft of all time. Various variants of the A300 were built to meet customer demands, often for diverse roles such as aerial refueling tankers, freighter models (new-build and conversions), combi aircraft, military airlifter, and VIP transport. Perhaps the most visually unique of the variants is the A300-600ST Beluga, an oversized cargo-carrying model operated by Airbus to carry aircraft sections between their manufacturing facilities. The A300 was the basis for, and retained a high level of commonality with, the second airliner produced by Airbus, the smaller Airbus A310. Operational history On 23 May 1974, the first A300 to enter service performed the first commercial flight of the type, flying from Paris to London, for Air France. Immediately after the launch, sales of the A300 were weak for some years, with most orders going to airlines that had an obligation to favor the domestically made product – notably Air France and Lufthansa, the first two airlines to place orders for the type. Following the appointment of Bernard Lathière as Henri Ziegler's replacement, an aggressive sales approach was adopted. Indian Airlines was the world's first domestic airline to purchase the A300, ordering three aircraft with three options. However, between December 1975 and May 1977, there were no sales for the type. During this period a number of "whitetail" A300s – completed but unsold aircraft – were completed and stored at Toulouse, and production fell to half an aircraft per month amid calls to pause production completely. During the flight testing of the A300B2, Airbus held a series of talks with Korean Air on the topic of developing a longer-range version of the A300, which would become the A300B4. In September 1974, Korean Air placed an order for four A300B4s with options for two further aircraft; this sale was viewed as significant as it was the first non-European international airline to order Airbus aircraft. Airbus had viewed South-East Asia as a vital market that was ready to be opened up and believed Korean Air to be the 'key'. Airlines operating the A300 on short-haul routes were forced to reduce frequencies to try and fill the aircraft. As a result, they lost passengers to airlines operating more frequent narrow-body flights. Eventually, Airbus had to build its own narrowbody aircraft (the A320) to compete with the Boeing 737 and McDonnell Douglas DC-9/MD-80. The saviour of the A300 was the advent of ETOPS, a revised FAA rule which allows twin-engine jets to fly long-distance routes that were previously off-limits to them. This enabled Airbus to develop the aircraft as a medium/long-range airliner. In 1977, US carrier Eastern Air Lines leased four A300s as an in-service trial. CEO Frank Borman was impressed that the A300 consumed 30% less fuel, even less than expected, than his fleet of L-1011s. Borman proceeded to order 23 A300s, becoming the first U.S. customer for the type. This order is often cited as the point at which Airbus came to be seen as a serious competitor to the large American aircraft-manufacturers Boeing and McDonnell Douglas. Aviation author John Bowen alleged that various concessions, such as loan guarantees from European governments and compensation payments, were a factor in the decision as well. The Eastern Air Lines breakthrough was shortly followed by an order from Pan Am. From then on, the A300 family sold well, eventually reaching a total of 561 delivered aircraft. In December 1977, Aerocondor Colombia became the first Airbus operator in Latin America, leasing one Airbus A300B4-2C, named Ciudad de Barranquilla. During the late 1970s, Airbus adopted a so-called 'Silk Road' strategy, targeting airlines in the Far East. As a result, The aircraft found particular favor with Asian airlines, being bought by Japan Air System, Korean Air, China Eastern Airlines, Thai Airways International, Singapore Airlines, Malaysia Airlines, Philippine Airlines, Garuda Indonesia, China Airlines, Pakistan International Airlines, Indian Airlines, Trans Australia Airlines and many others. As Asia did not have restrictions similar to the FAA 60-minutes rule for twin-engine airliners which existed at the time, Asian airlines used A300s for routes across the Bay of Bengal and South China Sea. In 1977, the A300B4 became the first ETOPS compliant aircraft, qualifying for Extended Twin Engine Operations over water, providing operators with more versatility in routing. In 1982 Garuda Indonesia became the first airline to fly the A300B4-200FFCC with the newly Forward-Facing Crew Cockpit concept, the world's first wide-body aircraft that only operated by two-man cockpit crew. By 1981, Airbus was growing rapidly, with over 400 aircraft sold to over forty airlines. In 1989, Chinese operator China Eastern Airlines received its first A300; by 2006, the airline operated around 18 A300s, making it the largest operator of both the A300 and the A310 at that time. On 31 May 2014, China Eastern officially retired the last A300-600 in its fleet, having begun drawing down the type in 2010. From 1997 to 2014, a single A300, designated A300 Zero-G, was operated by the European Space Agency (ESA), centre national d'études spatiales (CNES) and the German Aerospace Center (DLR) as a reduced-gravity aircraft for conducting research into microgravity; the A300 is the largest aircraft to ever have been used in this capacity. A typical flight would last for two and a half hours, enabling up to 30 parabolas to be performed per flight. By the 1990s, the A300 was being heavily promoted as a cargo freighter. The largest freight operator of the A300 is FedEx Express, which has 65 A300 aircraft in service as of May 2022. UPS Airlines also operates 52 freighter versions of the A300. The final version was the A300-600R and is rated for 180-minute ETOPS. The A300 has enjoyed renewed interest in the secondhand market for conversion to freighters; large numbers were being converted during the late 1990s. The freighter versions – either new-build A300-600s or converted ex-passenger A300-600s, A300B2s and B4s – account for most of the world's freighter fleet after the Boeing 747 freighter. The A300 provided Airbus the experience of manufacturing and selling airliners competitively. The basic fuselage of the A300 was later stretched (A330 and A340), shortened (A310), or modified into derivatives (A300-600ST Beluga Super Transporter). In 2006, unit cost of an −600F was $105 million. In March 2006, Airbus announced the impending closure of the A300/A310 final assembly line, making them the first Airbus aircraft to be discontinued. The final production A300, an A300F freighter, performed its initial flight on 18 April 2007, and was delivered to FedEx Express on 12 July 2007. Airbus has announced a support package to keep A300s flying commercially. Airbus offers the A330-200F freighter as a replacement for the A300 cargo variants. The life of UPS's fleet of 52 A300s, delivered from 2000 to 2006, will be extended to 2035 by a flight deck upgrade based around Honeywell Primus Epic avionics; new displays and flight management system (FMS), improved weather radar, a central maintenance system, and a new version of the current enhanced ground proximity warning system. With a light usage of only two to three cycles per day, it will not reach the maximum number of cycles by then. The first modification will be made at Airbus Toulouse in 2019 and certified in 2020. As of July 2017, there are 211 A300s in service with 22 operators, with the largest operator being FedEx Express with 68 A300-600F aircraft. Variants A300B1 The A300B1 was the first variant to take flight. It had a maximum takeoff weight (MTOW) of , was long and was powered by two General Electric CF6-50A engines. Only two prototypes of the variant were built before it was adapted into the A300B2, the first production variant of the airliner. The second prototype was leased to Trans European Airways in 1974. A300B2 A300B2-100 Responding to a need for more seats from Air France, Airbus decided that the first production variant should be larger than the original prototype A300B1. The CF6-50A powered A300B2-100 was longer than the A300B1 and had an increased MTOW of , allowing for 30 additional seats and bringing the typical passenger count up to 281, with capacity for 20 LD3 containers. Two prototypes were built and the variant made its maiden flight on 28 June 1973, became certified on 15 March 1974 and entered service with Air France on 23 May 1974. A300B2-200 For the A300B2-200, originally designated as the A300B2K, Krueger flaps were introduced at the leading-edge root, the slat angles were reduced from 20 degrees to 16 degrees, and other lift related changes were made in order to introduce a high-lift system. This was done to improve performance when operating at high-altitude airports, where the air is less dense and lift generation is reduced. The variant had an increased MTOW of and was powered by CF6-50C engines, was certified on 23 June 1976, and entered service with South African Airways in November 1976. CF6-50C1 and CF6-50C2 models were also later fitted depending on customer requirements, these became certified on 22 February 1978 and 21 February 1980 respectively. A300B2-320 The A300B2-320 introduced the Pratt & Whitney JT9D powerplant and was powered by JT9D-59A engines. It retained the MTOW of the B2-200, was certified on 4 January 1980, and entered service with Scandinavian Airlines on 18 February 1980, with only four being produced. A300B4 A300B4-100 The initial A300B4 variant, later named the A300B4-100, included a centre fuel tank for an increased fuel capacity of , and had an increased MTOW of . It also featured Krueger flaps and had a similar high-lift system to what was later fitted to the A300B2-200. The variant made its maiden flight on 26 December 1974, was certified on 26 March 1975, and entered service with Germanair in May 1975. A300B4-200 The A300B4-200 had an increased MTOW of and featured an additional optional fuel tank in the rear cargo hold, which would reduce the cargo capacity by two LD3 containers. The variant was certified on 26 April 1979. A300-600 The A300-600, officially designated as the A300B4-600, was slightly longer than the A300B2 and A300B4 variants and had an increased interior space from using a similar rear fuselage to the Airbus A310, this allowed it to have two additional rows of seats. It was initially powered by Pratt & Whitney JT9D-7R4H1 engines, but was later fitted with General Electric CF6-80C2 engines, with Pratt & Whitney PW4156 or PW4158 engines being introduced in 1986. Other changes include an improved wing featuring a recambered trailing edge, the incorporation of simpler single-slotted Fowler flaps, the deletion of slat fences, and the removal of the outboard ailerons after they were deemed unnecessary on the A310. The variant made its first flight on 8 July 1983, was certified on 9 March 1984, and entered service in June 1984 with Saudi Arabian Airlines. A total of 313 A300-600s (all versions) have been sold. The A300-600 uses the A310 cockpits, featuring digital technology and electronic displays, eliminating the need for a flight engineer. The FAA issues a single type rating which allows operation of both the A310 and A300-600. A300-600: (Official designation: A300B4-600) The baseline model of the −600 series. A300-620C: (Official designation: A300C4-620) A convertible-freighter version. Four delivered between 1984 and 1985. A300-600F: (Official designation: A300F4-600) The freighter version of the baseline −600. A300-600R: (Official designation: A300B4-600R) The increased-range −600, achieved by an additional trim fuel tank in the tail. First delivery in 1988 to American Airlines; all A300s built since 1989 (freighters included) are −600Rs. Japan Air System (later merged into Japan Airlines) took delivery of the last new-built passenger A300, an A300-622R, in November 2002. A300-600RC: (Official designation: A300C4-600R) The convertible-freighter version of the −600R. Two were delivered in 1999. A300-600RF: (Official designation: A300F4-600R) The freighter version of the −600R. All A300s delivered between November 2002 and 12 July 2007 (last ever A300 delivery) were A300-600RFs. A300B10 (A310) Airbus had demand for an aircraft smaller than the A300. On 7 July 1978, the A310 (initially the A300B10) was launched with orders from Swissair and Lufthansa. On 3 April 1982, the first prototype conducted its maiden flight and it received its type certification on 11 March 1983. Keeping the same eight-abreast cross-section, the A310 is shorter than the initial A300 variants, and has a smaller wing, down from . The A310 introduced a two-crew glass cockpit, later adopted for the A300-600 with a common type rating. It was powered by the same GE CF6-80 or Pratt & Whitney JT9D then PW4000 turbofans. It can seat 220 passengers in two classes, or 240 in all-economy, and can fly up to . It has overwing exits between the two main front and rear door pairs. In April 1983, the aircraft entered revenue service with Swissair and competed with the Boeing 767–200, introduced six months before. Its longer range and ETOPS regulations allowed it to be operated on transatlantic flights. Until the last delivery in June 1998, 255 aircraft were produced, as it was succeeded by the larger Airbus A330-200. It has cargo aircraft versions, and was derived into the Airbus A310 MRTT military tanker/transport. A300-600ST Commonly referred to as the Airbus Beluga or "Airbus Super Transporter," these five airframes are used by Airbus to ferry parts between the company's disparate manufacturing facilities, thus enabling workshare distribution. They replaced the four Aero Spacelines Super Guppys previously used by Airbus. ICAO code: A3ST Operators , there are 197 A300 family aircraft in commercial service. The five largest operators were FedEx Express (70), UPS Airlines (52), European Air Transport Leipzig (23), Iran Air (11), and Mahan Air (11). Deliveries Data through end of December 2007. Accidents and incidents As of June 2021, the A300 has been involved in 77 occurrences including 24 hull-loss accidents causing 1133 fatalities, and criminal occurrences and hijackings causing fatalities. Accidents with fatalities 21 September 1987: EgyptAir Airbus A300B4-203 touched down past the runway threshold. The right main gear hit runway lights and the aircraft collided with an antenna and fences. No passengers were on board the plane, but 5 crew members were killed. 28 September 1992: PIA Flight 268, an A300B4 crashed on approach near Kathmandu, Nepal. All 12 crew and 155 passengers perished. 26 April 1994: China Airlines Flight 140 (Taiwan) crashed at the end of runway at Nagoya, Japan, killing all 15 crew and 249 of 256 passengers on board. 26 September 1997: Garuda Indonesia Flight 152 was on approach to Polonia International Airport in Medan. The plane later crashed into a ravine in Buah Nabar due to ATC error and apparent haze that covers the country which limits the visibility. All 234 passengers and crew aboard perished in Indonesia's deadliest crash. 16 February 1998: China Airlines Flight 676 (Taiwan) crashed into a residential area close to CKS International Airport near Taipei, Taiwan. All 196 people on board were killed, including Taiwan's central bank president. Seven people on the ground were also killed. 12 November 2001: American Airlines Flight 587 crashed into Belle Harbor—a neighbourhood in Queens, New York, United States—shortly after takeoff from John F. Kennedy International Airport. The vertical stabiliser ripped off the aircraft after the rudder was mishandled during wake turbulence. All 260 people on board were killed, along with 5 people on the ground. It is the second-deadliest incident involving an A300 to date and the second-deadliest aircraft incident on United States soil. 14 April 2010: AeroUnion Flight 302, an A300B4-203F, crashed on a road short of the runway while attempting to land at Monterrey Airport in Mexico. Seven people (five crew members and two on the ground) were killed. 14 August 2013: UPS Flight 1354, an Airbus A300F4-622R, crashed outside the perimeter fence on approach to Birmingham–Shuttlesworth International Airport in Birmingham, Alabama, United States. Both crew members died. Hull losses 18 December 1983: Malaysian Airline System Flight 684, an Airbus A300B4 leased from Scandinavian Airlines System (SAS), registration OY-KAA, crashed short of the runway at Kuala Lumpur in bad weather while attempting to land on a flight from Singapore. All 247 persons aboard escaped unharmed but the aircraft was destroyed in the resulting fire. 24 April 1993: an Air Inter Airbus A300B2-1C was written off after colliding with a light pole while being pushed back at Montpellier. In November 1993, an Indian Airlines A300 plane crash landed near Hyderabad airport. There were no deaths but the aircraft was written off. 10 August 1994 – Korean Air Flight 2033 (Airbus A300) from Seoul to Jeju, the flight approached faster than usual to avoid potential windshear. Fifty feet above the runway the co-pilot, who was not flying the aircraft, decided that there was insufficient runway left to land and tried to perform a go-around against the captain's wishes.[18] The aircraft touched down 1,773 meters beyond the runway threshold. The aircraft could not be stopped on the remaining 1,227 meters of runway and overran at a speed of 104 knots. After striking the airport wall and a guard post at 30 knots, the aircraft burst into flames and was incinerated. The cabin crew was credited with safely evacuating all passengers although only half of the aircraft's emergency exits were usable} 1 March 2004, Pakistan International Airlines Flight 2002 burst 2 tyres whilst taking off from King Abdulaziz International Airport. Fragments of the tyre were ingested by the engines, this caused the engines to catch fire and an aborted takeoff was performed. Due to the fire substantial damage to the engine and the left wing caused the aircraft to be written off. All 261 passengers and 12 crew survived. 16 November 2012: an Air Contractors Airbus A300B4-203(F) EI-EAC, operating flight QY6321 on behalf of EAT Leipzig from Leipzig (Germany) to Bratislava (Slovakia), suffered a nose wheel collapse during roll out after landing at Bratislava's M. R. Štefánik Airport. All three crew members survived unharmed, the aircraft was written off. As of December 2017, the aircraft still was parked at a remote area of the airport between runways 13 and 22. 12 October 2015: An Airbus A300B4-200F Freighter operated by Egyptian Tristar cargo carrier crashed in Mogadishu, Somalia. All the passengers and crew members survived the crash. 1 October 2016: An Airbus A300-B4 registration PR-STN on a cargo flight between São Paulo-Guarulhos and Recife suffered a runway excursion after landing and the aft gear collapsed upon touchdown. Violent incidents 27 June 1976: Air France Flight 139, originating in Tel Aviv, Israel and carrying 248 passengers and a crew of 12 took off from Athens, Greece, headed for Paris, France. The flight was hijacked by terrorists, and was eventually flown to Entebbe Airport in Uganda. At the airport, Israeli commandos rescued 102 of the 106 hostages. 26 October 1986: Thai Airways Flight 620, an Airbus A300B4-601, originating in Bangkok suffered an explosion mid-flight. The aircraft descended rapidly and was able to land safely at Osaka. The aircraft was later repaired and there were no fatalities. The cause was a hand grenade brought onto the plane by a Japanese gangster of the Yamaguchi-gumi. 62 of the 247 people on board were injured. 3 July 1988: Iran Air Flight 655 was shot down by USS Vincennes in the Persian Gulf after being mistaken for an attacking Iranian F-14 Tomcat, killing all 290 passengers and crew. 15 February 1991: two Kuwait Airways A300C4-620s and two Boeing 767s that had been seized during Iraq's occupation of Kuwait were destroyed in coalition bombing of Mosul Airport. 24 December 1994: Air France Flight 8969 was hijacked at Houari Boumedienne Airport in Algiers, by four terrorists who belonged to the Armed Islamic Group. The terrorists apparently intended to crash the plane over the Eiffel Tower on Boxing Day. After a failed attempt to leave Marseille following a confrontational firefight between the terrorists and the GIGN French Special Forces, the result was the death of all four terrorists. (Snipers on the terminal front's roof shot dead two of the terrorists. The other two terrorists died as a result of gunshots in the cabin after approximately 20 minutes.) Three hostages including a Vietnamese diplomat were executed in Algiers, 229 hostages survived, many of them wounded by shrapnel. The almost 15-year-old aircraft was written off. 24 December 1999: Indian Airlines Flight IC 814 from Kathmandu, Nepal, to New Delhi was hijacked. After refuelling and offloading a few passengers, the flight was diverted to Kandahar, Afghanistan. A Nepalese man was murdered while the plane was in flight. 22 November 2003: European Air Transport OO-DLL, operating on behalf of DHL Aviation, was hit by an SA-14 'Gremlin' missile after takeoff from Baghdad International Airport. The aeroplane lost hydraulic pressure and thus the controls. After extending the landing gear to create more drag, the crew piloted the plane using differences in engine thrust and landed the plane with minimal further damage. The plane was repaired and offered for sale, but in April 2011 it still remained parked at Baghdad Intl. 25 August 2011: an A300B4-620 5A-IAY of Afriqiyah Airways and A300B4-622 5A-DLZ of Libyan Arab Airlines were both destroyed in fighting between pro- and anti-Gadaffi forces at Tripoli International Airport.

Alexander Fyodorovich Kerensky ( – 11 June 1970) was a Russian lawyer and revolutionary who led the Russian Provisional Government and the short-lived Russian Republic for three months from late July to early November 1917. After the February Revolution of 1917, he joined the newly formed provisional government, first as Minister of Justice, then as Minister of War, and after July as the government's second Minister-Chairman. He was the leader of the social-democratic Trudovik faction of the Socialist Revolutionary Party. Kerensky was also a vice-chairman of the Petrograd Soviet, a position that held a sizable amount of power. Kerensky became the prime minister of the Provisional Government, and his tenure was consumed with World War I. Despite mass opposition to the war, Kerensky chose to continue Russia's participation. His government cracked down on anti-war sentiment and dissent in 1917, which made his administration even more unpopular. Kerensky remained in power until the October Revolution. This revolution saw the Bolsheviks create a Leninist government, led by Vladimir Lenin, to replace his government. Kerensky fled Russia and lived the remainder of his life in exile. He divided his time between Paris and New York City. Kerensky worked for the Hoover Institution at Stanford University. Biography Early life and activism Alexander Kerensky was born in Simbirsk (now Ulyanovsk) on the Volga river on 4 May 1881 and was the eldest son in the family. His father, Fyodor Mikhailovich Kerensky, was a teacher and director of the local gymnasium and was later promoted to be an inspector of public schools. His paternal grandfather Mikhail Ivanovich served as a priest in the village of Kerenka in the Gorodishchensky district of the Penza Governorate from 1830. The surname Kerensky comes from the name of this village. His maternal grandfather was head of the Topographical Bureau of the Kazan Military District. His mother, Nadezhda Aleksandrovna (née Adler), was the granddaughter of a former serf who had managed to purchase his freedom before serfdom was abolished in 1861. He subsequently embarked upon a mercantile career, in which he prospered. This allowed him to move his business to Moscow, where he continued his success and became a wealthy Moscow merchant. Members of the Kerensky and Ulyanov families were friends; Kerensky's father was the teacher of Vladimir Ulyanov (Lenin) and had even secured him acceptance into the University of Kazan. In 1889, when Kerensky was eight, the family moved to Tashkent, where his father had been appointed the main inspector of public schools (superintendent). Alexander graduated with honours in 1899. The same year he entered St. Petersburg University, where he studied history and philology. The next year he switched to law. He earned his law degree in 1904 and married Olga Lvovna Baranovskaya, the daughter of a Russian general, the same year. Kerensky joined the Narodnik movement and worked as a legal counsel to victims of the Revolution of 1905. At the end of 1904, he was jailed on suspicion of belonging to a militant group. Afterwards, he gained a reputation for his work as a defence lawyer in a number of political trials of revolutionaries. In 1912, Kerensky became widely known when he visited the goldfields at the Lena River and published material about the Lena massacre. In the same year, Kerensky was elected to the Fourth Duma as a member of the Trudoviks, a socialist, non-Marxist labour party founded by Alexis Aladin that was associated with the Socialist-Revolutionary Party, and joined a Freemason society uniting the anti-monarchy forces that strived for democratic renewal of Russia. In fact, the Socialist Revolutionary Party bought Kerensky a house, as he otherwise would not be eligible for election to the Duma, according to the Russian property-laws. He soon became a significant member of the Progressive Bloc, which included several socialist parties, Mensheviks, and Liberals – but not Bolsheviks. He was a brilliant orator and skilled parliamentary leader of the socialist opposition to the government of Tsar Nicholas II. During the 4th Session of the Fourth Duma in spring 1915, Kerensky appealed to Mikhail Rodzianko with a request from the Council of elders to inform the tsar that to succeed in the war he must: 1) change his domestic policy, 2) proclaim a General Amnesty for political prisoners, 3) restore the Constitution of Finland, 4) declare autonomy of Poland, 5) provide national minorities autonomy in the field of culture, 6) abolish restrictions against Jews, 7) end religious intolerance, 8) stop the harassment of legal trade union organizations. Kerensky was an active member of the irregular Freemasonic lodge, the Grand Orient of Russia's Peoples, which derived from the Grand Orient of France. Kerensky was Secretary-General of the Grand Orient of Russia's Peoples and stood down following his ascent to the government in July 1917. He was succeeded by a Menshevik, Alexander Halpern. Rasputin In response to bitter resentments held against the imperial favourite Grigori Rasputin in the midst of Russia's failing effort in World War I, Kerensky, at the opening of the Duma on 2 November 1916, called the imperial ministers "hired assassins" and "cowards", and alleged that they were "guided by the contemptible Grishka Rasputin!" Grand Duke Nicholas Mikhailovich, Prince Georgy Lvov, and General Mikhail Alekseyev attempted to persuade the Emperor Nicholas II to send away the Empress Alexandra Feodorovna, Rasputin's steadfast patron, either to the Livadia Palace in Yalta or to Britain. Mikhail Rodzianko, Zinaida Yusupova (the mother of Felix Yusupov), Alexandra's sister Elisabeth, Grand Duchess Victoria and the empress's mother-in-law Maria Feodorovna also tried to influence and pressure the imperial couple to remove Rasputin from his position of influence within the imperial household, but without success. According to Kerensky, Rasputin had terrorised the empress by threatening to return to his native village. Members of the nobility murdered Rasputin in December 1916, and he was buried near the imperial residence in Tsarskoye Selo. Shortly after the February Revolution of 1917, Kerensky ordered soldiers to re-bury the corpse at an unmarked spot in the countryside. However, the truck broke down or was forced to stop because of the snow on Lesnoe Road outside of St. Petersburg. It is likely the corpse was incinerated (between 3 and 7 in the morning) in the cauldrons of the nearby boiler shop of the Saint Petersburg State Polytechnical University, including the coffin, without leaving a single trace. Russian Provisional Government of 1917 When the February Revolution broke out in 1917, Kerensky – together with Pavel Milyukov – was one of its most prominent leaders. As one of the Duma's most well-known speakers against the monarchy and as a lawyer and defender of many revolutionaries, Kerensky became a member of the Provisional Committee of the State Duma and was elected vice-chairman of the newly formed Petrograd Soviet. These two bodies, the Duma and the Petrograd Soviet, or – rather – their respective executive committees, soon became each other's antagonists on most matters except regarding the end of the tsar's autocracy. The Petrograd Soviet grew to include 3000 to 4000 members, and their meetings could drown in a blur of everlasting orations. At the meeting of to the Executive Committee of the Petrograd Soviet, or Ispolkom, formed a self-appointed committee, with (eventually) three members from each of the parties represented in the Soviet. Kerensky became one of the members representing the Socialist Revolutionary Party (the SRs). On , without any consultation with the government, the Ispolkom of the Soviet issued the infamous Order No. 1, intended only for the 160,000-strong Petrograd garrison, but soon interpreted as applicable to all soldiers at the front. The order stipulated that all military units should form committees like the Petrograd Soviet. This led to confusion and "stripping of officers' authority"; further, "Order No. 3" stipulated that the military was subordinate to Ispolkom in the political hierarchy. The ideas came from a group of socialists and aimed to limit the officers' power to military affairs. The socialist intellectuals believed the officers to be the most likely counterrevolutionary elements. Kerensky's role in these orders is unclear, but he participated in the decisions. But just as before the revolution he had defended many who disliked the tsar, he now saved the lives of many of the tsar's civil servants about to be lynched by mobs. Additionally, the Duma formed an executive committee which eventually became the Russian Provisional Government. As there was little trust between Ispolkom and this government (and as he was about to accept the office of Attorney General in the Provisional Government), Kerensky gave a most passionate speech, not just to the Ispolkom, but to the entire Petrograd Soviet. He then swore, as minister, never to violate democratic values, and ended his speech with the words "I cannot live without the people. In the moment you begin to doubt me, then kill me." The huge majority (workers and soldiers) gave him great applause, and Kerensky now became the first and the only one who participated in both the Provisional Government and the Ispolkom. As a link between Ispolkom and the Provisional Government, the quite ambitious Kerensky stood to benefit from this position. After the first government crisis over Pavel Milyukov's secret note re-committing Russia to its original war-aims on 2–4 May, Kerensky became the Minister of War and the dominant figure in the newly formed socialist-liberal coalition government. On 10 May (Julian calendar), Kerensky started for the front and visited one division after another, urging the men to do their duty. His speeches were impressive and convincing for the moment, but had little lasting effect. Under Allied pressure to continue the war, he launched what became known as the Kerensky Offensive against the Austro-Hungarian/German South Army on . At first successful, the offensive soon met strong resistance and the Central Powers riposted with a strong counter-attack. The Russian army retreated and suffered heavy losses, and it became clear from many incidents of desertion, sabotage, and mutiny that the army was no longer willing to attack. The military heavily criticised Kerensky for his liberal policies, which included stripping officers of their mandates and handing over control to revolutionary-inclined "soldier committees" () instead; abolition of the death penalty; and allowing revolutionary agitators to be present at the front. Many officers jokingly referred to commander-in-chief Kerensky as the "persuader-in-chief". On 2 July 1917 the Provisional Government's first coalition collapsed over the question of Ukraine's autonomy. Following the July Days unrest in Petrograd (3–7 July [16–20 July, N.S.] 1917) and the official suppression of the Bolsheviks, Kerensky succeeded Prince Georgy Lvov as Russia's prime minister on . Following the Kornilov Affair, an attempted military coup d'état at the end of August, and the resignation of the other ministers, he appointed himself Supreme Commander-in-Chief, as well. On 15 September Kerensky proclaimed Russia a republic, which was contrary to the non-socialists' understanding that the Provisional Government should hold power only until a Constituent Assembly should meet to decide Russia's form of government, but which was in line with the long-proclaimed aim of the Socialist Revolutionary Party. He formed a five-member Directory, which consisted of himself, Minister of Foreign Affairs Mikhail Tereshchenko, Minister of War General Aleksandr Verkhovsky, Minister of the Navy Admiral Dmitry Verderevsky and Minister of Posts and Telegraphs . He retained his post in the final coalition government in October 1917 until the Bolsheviks overthrew it on . Kerensky faced a major challenge: three years of participation in World War had exhausted Russia, while the provisional government offered little motivation for a victory outside of continuing Russia's obligations towards its allies. Russia's continued involvement in the war was not popular among the lower and middle classes, and especially not popular among the soldiers. They had all believed that Russia would stop fighting when the Provisional Government took power, and subsequently felt deceived. Furthermore, Vladimir Lenin and his Bolshevik party were promising "peace, land, and bread" under a communist system. The Russian army, war-weary, ill-equipped, dispirited and ill-disciplined, was disintegrating, with soldiers deserting in large numbers. By autumn 1917, an estimated two million men had unofficially left the army. Kerensky and other political leaders continued Russia's involvement in World War I, thinking that a glorious victory was the only road forward, and fearing that the economy, already under huge stress from the war effort, might become increasingly unstable if vital supplies from France and from the United Kingdom ceased flowing. The dilemma of whether to withdraw was a great one, and Kerensky's inconsistent and impractical policies further destabilised the army and the country at large. Furthermore, Kerensky adopted a policy that isolated the right-wing conservatives, both democratic and monarchist-oriented. His philosophy of "no enemies to the left" greatly empowered the Bolsheviks and gave them a free hand, allowing them to take over the military arm or "voyenka" () of the Petrograd and Moscow Soviets. His arrest of Lavr Kornilov and other officers left him without strong allies against the Bolsheviks, who ended up being Kerensky's strongest and most determined adversaries, as opposed to the right wing, which evolved into the White movement. October Revolution of 1917 During the Kornilov Affair, Kerensky had distributed arms to the Petrograd workers, and by November most of these armed workers had gone over to the Bolsheviks. On 1917, the Bolsheviks launched the second Russian revolution of the year. Kerensky's government in Petrograd had almost no support in the city. Only one small force, a subdivision of the 2nd company of the First Petrograd Women's Battalion, also known as The Women's Death Battalion, was willing to fight for the government against the Bolsheviks, but this force was overwhelmed by the numerically superior pro-Bolshevik forces, defeated, and captured. The Bolsheviks overthrew the government rapidly by seizing governmental buildings and the Winter Palace. Kerensky escaped the Bolsheviks and fled to Pskov, where he rallied some loyal troops for an attempt to re-take the city. His troops managed to capture Tsarskoye Selo but were beaten the next day at Pulkovo. Kerensky narrowly escaped, and he spent the next few weeks in hiding before fleeing the country, eventually arriving in France. During the Russian Civil War, he supported neither side, as he opposed both the Bolshevik regime and the White Movement. Personal life Kerensky was married to Olga Lvovna Baranovskaya and they had two sons, Oleg (1905–1984) and Gleb (1907–1990), who both went on to become engineers. Kerensky's grandson (also named Oleg), according to the Internet Movie Database, played his grandfather's role in the 1981 film Reds. Kerensky and Olga were divorced in 1939 soon after he settled in Paris, and, in 1939, while visiting the United States he met and married Lydia Ellen "Nell" Tritton (1899–1946), the Australian former journalist who had become his press secretary and translator. The marriage took place in Martins Creek, Pennsylvania. When Germany invaded France in 1940, they emigrated to the United States. After the Axis invasion of the Soviet Union in 1941, Kerensky offered his support to Joseph Stalin. When his wife Nell became terminally ill in 1945, Kerensky travelled with her to Brisbane, Australia, and lived there with her family. She suffered a stroke in February 1946, and he remained there until her death on 10 April 1946. Kerensky then returned to the United States, where he spent the rest of his life. Kerensky eventually settled in New York City, living on the Upper East Side on 91st Street near Central Park but spent much of his time at the Hoover Institution at Stanford University in California, where he both used and contributed to the Institution's huge archive on Russian history, and where he taught graduate courses. He wrote and broadcast extensively on Russian politics and history. His last public lecture was delivered at Kalamazoo College in Kalamazoo, Michigan, in October 1967. Death Kerensky died of arteriosclerotic heart disease at St. Luke's Hospital in New York City on 11 June 1970 after being initially admitted from injuries sustained in a fall. At 89, he was one of the last surviving major participants in the turbulent events of 1917. The local Russian Orthodox Churches in New York City refused to grant Kerensky burial rites because of his association with Freemasonry, and because they saw him as largely responsible for the Bolsheviks seizing power. A Serbian Orthodox Church also refused burial rites. Kerensky's body was flown to London, where he was buried at the non-denominational Putney Vale Cemetery. Works The Prelude to Bolshevism (1919). .

Automated theorem proving (also known as ATP or automated deduction) is a subfield of automated reasoning and mathematical logic dealing with proving mathematical theorems by computer programs. Automated reasoning over mathematical proof was a major impetus for the development of computer science. Logical foundations While the roots of formalised logic go back to Aristotle, the end of the 19th and early 20th centuries saw the development of modern logic and formalised mathematics. Frege's Begriffsschrift (1879) introduced both a complete propositional calculus and what is essentially modern predicate logic. His Foundations of Arithmetic, published in 1884, expressed (parts of) mathematics in formal logic. This approach was continued by Russell and Whitehead in their influential Principia Mathematica, first published 1910–1913, and with a revised second edition in 1927. Russell and Whitehead thought they could derive all mathematical truth using axioms and inference rules of formal logic, in principle opening up the process to automatisation. In 1920, Thoralf Skolem simplified a previous result by Leopold Löwenheim, leading to the Löwenheim–Skolem theorem and, in 1930, to the notion of a Herbrand universe and a Herbrand interpretation that allowed (un)satisfiability of first-order formulas (and hence the validity of a theorem) to be reduced to (potentially infinitely many) propositional satisfiability problems. In 1929, Mojżesz Presburger showed that the first-order theory of the natural numbers with addition and equality (now called Presburger arithmetic in his honor) is decidable and gave an algorithm that could determine if a given sentence in the language was true or false. However, shortly after this positive result, Kurt Gödel published On Formally Undecidable Propositions of Principia Mathematica and Related Systems (1931), showing that in any sufficiently strong axiomatic system there are true statements that cannot be proved in the system. This topic was further developed in the 1930s by Alonzo Church and Alan Turing, who on the one hand gave two independent but equivalent definitions of computability, and on the other gave concrete examples of undecidable questions. First implementations Shortly after World War II, the first general-purpose computers became available. In 1954, Martin Davis programmed Presburger's algorithm for a JOHNNIAC vacuum-tube computer at the Institute for Advanced Study in Princeton, New Jersey. According to Davis, "Its great triumph was to prove that the sum of two even numbers is even". More ambitious was the Logic Theorist in 1956, a deduction system for the propositional logic of the Principia Mathematica, developed by Allen Newell, Herbert A. Simon and J. C. Shaw. Also running on a JOHNNIAC, the Logic Theorist constructed proofs from a small set of propositional axioms and three deduction rules: modus ponens, (propositional) variable substitution, and the replacement of formulas by their definition. The system used heuristic guidance, and managed to prove 38 of the first 52 theorems of the Principia. The "heuristic" approach of the Logic Theorist tried to emulate human mathematicians, and could not guarantee that a proof could be found for every valid theorem even in principle. In contrast, other, more systematic algorithms achieved, at least theoretically, completeness for first-order logic. Initial approaches relied on the results of Herbrand and Skolem to convert a first-order formula into successively larger sets of propositional formulae by instantiating variables with terms from the Herbrand universe. The propositional formulas could then be checked for unsatisfiability using a number of methods. Gilmore's program used conversion to disjunctive normal form, a form in which the satisfiability of a formula is obvious. Decidability of the problem Depending on the underlying logic, the problem of deciding the validity of a formula varies from trivial to impossible. For the common case of propositional logic, the problem is decidable but co-NP-complete, and hence only exponential-time algorithms are believed to exist for general proof tasks. For a first-order predicate calculus, Gödel's completeness theorem states that the theorems (provable statements) are exactly the semantically valid well-formed formulas, so the valid formulas are computably enumerable: given unbounded resources, any valid formula can eventually be proven. However, invalid formulas (those that are not entailed by a given theory), cannot always be recognized. The above applies to first-order theories, such as Peano arithmetic. However, for a specific model that may be described by a first-order theory, some statements may be true but undecidable in the theory used to describe the model. For example, by Gödel's incompleteness theorem, we know that any consistent theory whose axioms are true for the natural numbers cannot prove all first-order statements true for the natural numbers, even if the list of axioms is allowed to be infinite enumerable. It follows that an automated theorem prover will fail to terminate while searching for a proof precisely when the statement being investigated is undecidable in the theory being used, even if it is true in the model of interest. Despite this theoretical limit, in practice, theorem provers can solve many hard problems, even in models that are not fully described by any first-order theory (such as the integers). Related problems A simpler, but related, problem is proof verification, where an existing proof for a theorem is certified valid. For this, it is generally required that each individual proof step can be verified by a primitive recursive function or program, and hence the problem is always decidable. Since the proofs generated by automated theorem provers are typically very large, the problem of proof compression is crucial, and various techniques aiming at making the prover's output smaller, and consequently more easily understandable and checkable, have been developed. Proof assistants require a human user to give hints to the system. Depending on the degree of automation, the prover can essentially be reduced to a proof checker, with the user providing the proof in a formal way, or significant proof tasks can be performed automatically. Interactive provers are used for a variety of tasks, but even fully automatic systems have proved a number of interesting and hard theorems, including at least one that has eluded human mathematicians for a long time, namely the Robbins conjecture. However, these successes are sporadic, and work on hard problems usually requires a proficient user. Another distinction is sometimes drawn between theorem proving and other techniques, where a process is considered to be theorem proving if it consists of a traditional proof, starting with axioms and producing new inference steps using rules of inference. Other techniques would include model checking, which, in the simplest case, involves brute-force enumeration of many possible states (although the actual implementation of model checkers requires much cleverness, and does not simply reduce to brute force). There are hybrid theorem proving systems that use model checking as an inference rule. There are also programs that were written to prove a particular theorem, with a (usually informal) proof that if the program finishes with a certain result, then the theorem is true. A good example of this was the machine-aided proof of the four color theorem, which was very controversial as the first claimed mathematical proof that was essentially impossible to verify by humans due to the enormous size of the program's calculation (such proofs are called non-surveyable proofs). Another example of a program-assisted proof is the one that shows that the game of Connect Four can always be won by the first player. Industrial uses Commercial use of automated theorem proving is mostly concentrated in integrated circuit design and verification. Since the Pentium FDIV bug, the complicated floating point units of modern microprocessors have been designed with extra scrutiny. AMD, Intel and others use automated theorem proving to verify that division and other operations are correctly implemented in their processors. First-order theorem proving In the late 1960s agencies funding research in automated deduction began to emphasize the need for practical applications. One of the first fruitful areas was that of program verification whereby first-order theorem provers were applied to the problem of verifying the correctness of computer programs in languages such as Pascal, Ada, etc. Notable among early program verification systems was the Stanford Pascal Verifier developed by David Luckham at Stanford University. This was based on the Stanford Resolution Prover also developed at Stanford using John Alan Robinson's resolution principle. This was the first automated deduction system to demonstrate an ability to solve mathematical problems that were announced in the Notices of the American Mathematical Society before solutions were formally published. First-order theorem proving is one of the most mature subfields of automated theorem proving. The logic is expressive enough to allow the specification of arbitrary problems, often in a reasonably natural and intuitive way. On the other hand, it is still semi-decidable, and a number of sound and complete calculi have been developed, enabling fully automated systems. More expressive logics, such as higher-order logics, allow the convenient expression of a wider range of problems than first-order logic, but theorem proving for these logics is less well developed. Benchmarks, competitions, and sources The quality of implemented systems has benefited from the existence of a large library of standard benchmark examples—the Thousands of Problems for Theorem Provers (TPTP) Problem Library—as well as from the CADE ATP System Competition (CASC), a yearly competition of first-order systems for many important classes of first-order problems. Some important systems (all have won at least one CASC competition division) are listed below. E is a high-performance prover for full first-order logic, but built on a purely equational calculus, originally developed in the automated reasoning group of Technical University of Munich under the direction of Wolfgang Bibel, and now at Baden-Württemberg Cooperative State University in Stuttgart. Otter, developed at the Argonne National Laboratory, is based on first-order resolution and paramodulation. Otter has since been replaced by Prover9, which is paired with Mace4. SETHEO is a high-performance system based on the goal-directed model elimination calculus, originally developed by a team under direction of Wolfgang Bibel. E and SETHEO have been combined (with other systems) in the composite theorem prover E-SETHEO. Vampire was originally developed and implemented at Manchester University by Andrei Voronkov and Kryštof Hoder. It is now developed by a growing international team. It has won the FOF division (among other divisions) at the CADE ATP System Competition regularly since 2001. Waldmeister is a specialized system for unit-equational first-order logic developed by Arnim Buch and Thomas Hillenbrand. It won the CASC UEQ division for fourteen consecutive years (1997–2010). SPASS is a first-order logic theorem prover with equality. This is developed by the research group Automation of Logic, Max Planck Institute for Computer Science. The Theorem Prover Museum is an initiative to conserve the sources of theorem prover systems for future analysis, since they are important cultural/scientific artefacts. It has the sources of many of the systems mentioned above.

Agent Orange is a chemical herbicide and defoliant, one of the tactical use Rainbow Herbicides. It was used by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand, during the Vietnam War from 1961 to 1971. It is a mixture of equal parts of two herbicides, 2,4,5-T and 2,4-D. In addition to its damaging environmental effects, traces of dioxin (mainly TCDD, the most toxic of its type) found in the mixture have caused major health problems for many individuals who were exposed, and their offspring. Agent Orange was produced in the United States from the late 1940s and was used in industrial agriculture, and was also sprayed along railroads and power lines to control undergrowth in forests. During the Vietnam War, the U.S. military procured over , consisting of a fifty-fifty mixture of 2,4-D and dioxin-contaminated 2,4,5-T. Nine chemical companies produced it: Dow Chemical Company, Monsanto Company, Diamond Shamrock Corporation, Hercules Inc., Thompson Hayward Chemical Co., United States Rubber Company (Uniroyal), Thompson Chemical Co., Hoffman-Taff Chemicals, Inc., and Agriselect. The government of Vietnam says that up to four million people in Vietnam were exposed to the defoliant, and as many as three million people have suffered illness because of Agent Orange, while the Vietnamese Red Cross estimates that up to one million people were disabled or have health problems as a result of exposure to Agent Orange. The United States government has described these figures as unreliable, while documenting cases of leukemia, Hodgkin's lymphoma, and various kinds of cancer in exposed U.S. military veterans. An epidemiological study done by the Centers for Disease Control and Prevention showed that there was an increase in the rate of birth defects of the children of military personnel as a result of Agent Orange. Agent Orange has also caused enormous environmental damage in Vietnam. Over or of forest were defoliated. Defoliants eroded tree cover and seedling forest stock, making reforestation difficult in numerous areas. Animal species diversity is sharply reduced in contrast with unsprayed areas. The environmental destruction caused by this defoliation has been described by Swedish Prime Minister Olof Palme, lawyers, historians and other academics as an ecocide. The use of Agent Orange in Vietnam resulted in numerous legal actions. The United Nations ratified United Nations General Assembly Resolution 31/72 and the Environmental Modification Convention. Lawsuits filed on behalf of both U.S. and Vietnamese veterans sought compensation for damages. Agent Orange was first used by the British Armed Forces in Malaya during the Malayan Emergency. It was also used by the U.S. military in Laos and Cambodia during the Vietnam War because forests near the border with Vietnam were used by the Viet Cong. Chemical composition The active ingredient of Agent Orange was an equal mixture of two phenoxy herbicides – 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) – in iso-octyl ester form, which contained traces of the dioxin 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). TCDD was a trace (typically 2-3 ppm, ranging from 50 ppb to 50 ppm) - but significant - contaminant of Agent Orange. Toxicology TCDD is the most toxic of the dioxins and is classified as a human carcinogen by the U.S. Environmental Protection Agency (EPA). The fat-soluble nature of TCDD causes it to enter the body readily through physical contact or ingestion. Dioxins accumulate easily in the food chain. Dioxin enters the body by attaching to a protein called the aryl hydrocarbon receptor (AhR), a transcription factor. When TCDD binds to AhR, the protein moves to the nucleus, where it influences gene expression. According to U.S. government reports, if not bound chemically to a biological surface such as soil, leaves or grass, Agent Orange dries quickly after spraying and breaks down within hours to days when exposed to sunlight and is no longer harmful. Development Several herbicides were developed as part of efforts by the United States and the United Kingdom to create herbicidal weapons for use during World War II. These included 2,4-D, 2,4,5-T, MCPA (2-methyl-4-chlorophenoxyacetic acid, 1414B and 1414A, recoded LN-8 and LN-32), and isopropyl phenylcarbamate (1313, recoded LN-33). In 1943, the United States Department of the Army contracted botanist (and later bioethicist) Arthur Galston, who discovered the defoliants later used in Agent Orange, and his employer University of Illinois Urbana-Champaign to study the effects of 2,4-D and 2,4,5-T on cereal grains (including rice) and broadleaf crops. While a graduate and post-graduate student at the University of Illinois, Galston's research and dissertation focused on finding a chemical means to make soybeans flower and fruit earlier. He discovered both that 2,3,5-triiodobenzoic acid (TIBA) would speed up the flowering of soybeans and that in higher concentrations it would defoliate the soybeans. From these studies arose the concept of using aerial applications of herbicides to destroy enemy crops to disrupt their food supply. In early 1945, the U.S. Army ran tests of various 2,4-D and 2,4,5-T mixtures at the Bushnell Army Airfield in Florida. As a result, the U.S. began a full-scale production of 2,4-D and 2,4,5-T and would have used it against Japan in 1946 during Operation Downfall if the war had continued. In the years after the war, the U.S. tested 1,100 compounds, and field trials of the more promising ones were done at British stations in India and Australia, in order to establish their effects in tropical conditions, as well as at the U.S. testing ground in Florida. Between 1950 and 1952, trials were conducted in Tanganyika, at Kikore and Stunyansa, to test arboricides and defoliants under tropical conditions. The chemicals involved were 2,4-D, 2,4,5-T, and endothall (3,6-endoxohexahydrophthalic acid). During 1952–53, the unit supervised the aerial spraying of 2,4,5-T in Kenya to assess the value of defoliants in the eradication of tsetse fly. Early use In Malaya, the local unit of Imperial Chemical Industries researched defoliants as weed killers for rubber plantations. Roadside ambushes by the Malayan National Liberation Army were a danger to the British military during the Malayan Emergency (1948–1960), several trials were made to defoliate vegetation that might hide ambush sites, but hand removal was found cheaper. A detailed account of how the British experimented with the spraying of herbicides was written by two scientists, E.K. Woodford of Agricultural Research Council's Unit of Experimental Agronomy and H.G.H. Kearns of the University of Bristol. After the Malayan Emergency ended in 1960, the U.S. considered the British precedent in deciding that the use of defoliants was a legal tactic of warfare. Secretary of State Dean Rusk advised President John F. Kennedy that the British had established a precedent for warfare with herbicides in Malaya. Use in the Vietnam War In mid-1961, President Ngo Dinh Diem of South Vietnam asked the United States to help defoliate the lush jungle that was providing cover to his Communist enemies. In August of that year, the Republic of Vietnam Air Force conducted herbicide operations with American help. Diem's request launched a policy debate in the White House and the State and Defense Departments. Many U.S. officials supported herbicide operations, pointing out that the British had already used herbicides and defoliants in Malaya during the 1950s. In November 1961, Kennedy authorized the start of Operation Ranch Hand, the codename for the United States Air Force's herbicide program in Vietnam. The herbicide operations were formally directed by the government of South Vietnam. During the Vietnam War, between 1962 and 1971, the United States military sprayed nearly of various chemicals – the "rainbow herbicides" and defoliants – in Vietnam, eastern Laos, and parts of Cambodia as part of Operation Ranch Hand, reaching its peak from 1967 to 1969. For comparison purposes, an olympic size pool holds approximately . As the British did in Malaya, the goal of the U.S. was to defoliate rural/forested land, depriving guerrillas of food and concealment and clearing sensitive areas such as around base perimeters and possible ambush sites along roads and canals. Samuel P. Huntington argued that the program was also a part of a policy of forced draft urbanization, which aimed to destroy the ability of peasants to support themselves in the countryside, forcing them to flee to the U.S.-dominated cities, depriving the guerrillas of their rural support base. Agent Orange was usually sprayed from helicopters or from low-flying C-123 Provider aircraft, fitted with sprayers and "MC-1 Hourglass" pump systems and chemical tanks. Spray runs were also conducted from trucks, boats, and backpack sprayers. Altogether, over of Agent Orange were applied. The first batch of herbicides was unloaded at Tan Son Nhut Air Base in South Vietnam, on January 9, 1962. U.S. Air Force records show at least 6,542 spraying missions took place over the course of Operation Ranch Hand. By 1971, 12 percent of the total area of South Vietnam had been sprayed with defoliating chemicals, at an average concentration of 13 times the recommended U.S. Department of Agriculture application rate for domestic use. In South Vietnam alone, an estimated of agricultural land was ultimately destroyed. In some areas, TCDD concentrations in soil and water were hundreds of times greater than the levels considered safe by the EPA. The campaign destroyed of upland and mangrove forests and thousands of square kilometres of crops. Overall, more than 20% of South Vietnam's forests were sprayed at least once over the nine-year period. 3.2% of South Vietnam's cultivated land was sprayed at least once between 1965 and 1971. 90% of herbicide use was directed at defoliation. The U.S. military began targeting food crops in October 1962, primarily using Agent Blue; the American public was not made aware of the crop destruction programs until 1965 (and it was then believed that crop spraying had begun that spring). In 1965, 42% of all herbicide spraying was dedicated to food crops. In 1965, members of the U.S. Congress were told, "crop destruction is understood to be the more important purpose ... but the emphasis is usually given to the jungle defoliation in public mention of the program." The first official acknowledgment of the programs came from the State Department in March 1966. When crops were destroyed, the Viet Cong would compensate for the loss of food by confiscating more food from local villages. Some military personnel reported being told they were destroying crops used to feed guerrillas, only to later discover, most of the destroyed food was actually produced to support the local civilian population. For example, according to Wil Verwey, 85% of the crop lands in Quang Ngai province were scheduled to be destroyed in 1970 alone. He estimated this would have caused famine and left hundreds of thousands of people without food or malnourished in the province. According to a report by the American Association for the Advancement of Science, the herbicide campaign had disrupted the food supply of more than 600,000 people by 1970. Many experts at the time, including Arthur Galston, opposed herbicidal warfare because of concerns about the side effects to humans and the environment by indiscriminately spraying the chemical over a wide area. As early as 1966, resolutions were introduced to the United Nations charging that the U.S. was violating the 1925 Geneva Protocol, which regulated the use of chemical and biological weapons in international conflicts. The U.S. defeated most of the resolutions, arguing that Agent Orange was not a chemical or a biological weapon as it was considered a herbicide and a defoliant and it was used in effort to destroy plant crops and to deprive the enemy of concealment and not meant to target human beings. The U.S. delegation argued that a weapon, by definition, is any device used to injure, defeat, or destroy living beings, structures, or systems, and Agent Orange did not qualify under that definition. It also argued that if the U.S. were to be charged for using Agent Orange, then the United Kingdom and its Commonwealth nations should be charged since they also used it widely during the Malayan Emergency in the 1950s. In 1969, the United Kingdom commented on the draft Resolution 2603 (XXIV): "The evidence seems to us to be notably inadequate for the assertion that the use in war of chemical substances specifically toxic to plants is prohibited by international law." The environmental destruction caused by this defoliation has been described by Swedish Prime Minister Olof Palme, lawyers, historians and other academics as an ecocide. A study carried out by the Bionetic Research Laboratories between 1965 and 1968 found malformations in test animals caused by 2,4,5-T, a component of Agent Orange. The study was later brought to the attention of the White House in October 1969. Other studies reported similar results and the Department of Defense began to reduce the herbicide operation. On April 15, 1970, it was announced that the use of Agent Orange was suspended. Two brigades of the Americal Division in the summer of 1970 continued to use Agent Orange for crop destruction in violation of the suspension. An investigation led to disciplinary action against the brigade and division commanders because they had falsified reports to hide its use. Defoliation and crop destruction were completely stopped by June 30, 1971. Health effects There are various types of cancer associated with Agent Orange, including chronic B-cell leukemia, Hodgkin's lymphoma, multiple myeloma, non-Hodgkin's lymphoma, prostate cancer, respiratory cancer, lung cancer, and soft tissue sarcomas. Vietnamese people The government of Vietnam states that 4 million of its citizens were exposed to Agent Orange, and as many as 3 million have suffered illnesses because of it; these figures include their children who were exposed. The Red Cross of Vietnam estimates that up to 1 million people are disabled or have health problems due to Agent Orange contamination. The United States government has challenged these figures as being unreliable. According to a study by Dr. Nguyen Viet Nhan, children in the areas where Agent Orange was used have been affected and have multiple health problems, including cleft palate, mental disabilities, hernias, and extra fingers and toes. In the 1970s, high levels of dioxin were found in the breast milk of South Vietnamese women, and in the blood of U.S. military personnel who had served in Vietnam. The most affected zones are the mountainous area along Truong Son (Long Mountains) and the border between Vietnam and Cambodia. The affected residents are living in substandard conditions with many genetic diseases. In 2006, Anh Duc Ngo and colleagues of the University of Texas Health Science Center published a meta-analysis that exposed a large amount of heterogeneity (different findings) between studies, a finding consistent with a lack of consensus on the issue. Despite this, statistical analysis of the studies they examined resulted in data that the increase in birth defects/relative risk (RR) from exposure to agent orange/dioxin "appears" to be on the order of 3 in Vietnamese-funded studies, but 1.29 in the rest of the world. There is data near the threshold of statistical significance suggesting Agent Orange contributes to still-births, cleft palate, and neural tube defects, with spina bifida being the most statistically significant defect. The large discrepancy in RR between Vietnamese studies and those in the rest of the world has been ascribed to bias in the Vietnamese studies. Twenty-eight of the former U.S. military bases in Vietnam where the herbicides were stored and loaded onto airplanes may still have high levels of dioxins in the soil, posing a health threat to the surrounding communities. Extensive testing for dioxin contamination has been conducted at the former U.S. airbases in Da Nang, Phù Cát District and Biên Hòa. Some of the soil and sediment on the bases have extremely high levels of dioxin requiring remediation. The Da Nang Air Base has dioxin contamination up to 350 times higher than international recommendations for action. The contaminated soil and sediment continue to affect the citizens of Vietnam, poisoning their food chain and causing illnesses, serious skin diseases and a variety of cancers in the lungs, larynx, and prostate. U.S. veterans While in Vietnam, US-allied soldiers were told not to worry about agent orange and were persuaded the chemical was harmless. After returning home, Vietnam veterans began to suspect their ill health or the instances of their wives having miscarriages or children born with birth defects might be related to Agent Orange and the other toxic herbicides to which they had been exposed in Vietnam. Veterans began to file claims in 1977 to the Department of Veterans Affairs for disability payments for health care for conditions they believed were associated with exposure to Agent Orange, or more specifically, dioxin, but their claims were denied unless they could prove the condition began when they were in the service or within one year of their discharge. In order to qualify for compensation, veterans must have served on or near the perimeters of military bases in Thailand during the Vietnam Era, where herbicides were tested and stored outside of Vietnam, veterans who were crew members on C-123 planes flown after the Vietnam War, or were associated with Department of Defense (DoD) projects to test, dispose of, or store herbicides in the U.S. By April 1993, the Department of Veterans Affairs had compensated only 486 victims, although it had received disability claims from 39,419 soldiers who had been exposed to Agent Orange while serving in Vietnam. In a November 2004 Zogby International poll of 987 people, 79% of respondents thought the U.S. chemical companies which produced Agent Orange defoliant should compensate U.S. soldiers who were affected by the toxic chemical used during the war in Vietnam and 51% said they supported compensation for Vietnamese Agent Orange victims. National Academy of Medicine Starting in the early 1990s, the federal government directed the Institute of Medicine (IOM), now known as the National Academy of Medicine, to issue reports every 2 years on the health effects of Agent Orange and similar herbicides. First published in 1994 and titled Veterans and Agent Orange, the IOM reports assess the risk of both cancer and non-cancer health effects. Each health effect is categorized by evidence of association based on available research data. The last update was published in 2016, entitled "Veterans and Agent Orange: Update 2014." The report shows sufficient evidence of an association with soft tissue sarcoma; non-Hodgkin lymphoma (NHL); Hodgkin disease; Chronic lymphocytic leukemia (CLL); including hairy cell leukemia and other chronic B-cell leukemias. Limited or suggested evidence of an association was linked with respiratory cancers (lung, bronchus, trachea, larynx); prostate cancer; multiple myeloma; and bladder cancer. Numerous other cancers were determined to have inadequate or insufficient evidence of links to Agent Orange. The National Academy of Medicine has repeatedly concluded that any evidence suggestive of an association between Agent Orange and prostate cancer is, "limited because chance, bias, and confounding could not be ruled out with confidence." At the request of the Veterans Administration, the Institute Of Medicine evaluated whether service in these C-123 aircraft could have plausibly exposed soldiers and been detrimental to their health. Their report "Post-Vietnam Dioxin Exposure in Agent Orange-Contaminated C-123 Aircraft" confirmed it. U.S. Public Health Service Publications by the United States Public Health Service have shown that Vietnam veterans, overall, have increased rates of cancer, and nerve, digestive, skin, and respiratory disorders. The Centers for Disease Control and Prevention notes that in particular, there are higher rates of acute/chronic leukemia, Hodgkin's lymphoma and non-Hodgkin's lymphoma, throat cancer, prostate cancer, lung cancer, colon cancer, Ischemic heart disease, soft tissue sarcoma, and liver cancer. With the exception of liver cancer, these are the same conditions the U.S. Veterans Administration has determined may be associated with exposure to Agent Orange/dioxin and are on the list of conditions eligible for compensation and treatment. Military personnel who were involved in storage, mixture and transportation (including aircraft mechanics), and actual use of the chemicals were probably among those who received the heaviest exposures. Military members who served on Okinawa also claim to have been exposed to the chemical, but there is no verifiable evidence to corroborate these claims. Some studies have suggested that veterans exposed to Agent Orange may be more at risk of developing prostate cancer and potentially more than twice as likely to develop higher-grade, more lethal prostate cancers. However, a critical analysis of these studies and 35 others consistently found that there was no significant increase in prostate cancer incidence or mortality in those exposed to Agent Orange or 2,3,7,8-tetracholorodibenzo-p-dioxin. U.S. Veterans of Laos and Cambodia During the Vietnam War, the United States fought the North Vietnamese, and their allies, in Laos and Cambodia, including heavy bombing campaigns. They also sprayed large quantities of Agent Orange in each of those countries. According to one estimate, the U.S. dropped in Laos and in Cambodia. Because Laos and Cambodia were both officially neutral during the Vietnam War, the U.S. attempted to keep secret its military operations in those countries, from the American population and has largely avoided compensating American veterans and CIA personnel stationed in Cambodia and Laos who suffered permanent injuries as a result of exposure to Agent Orange there. One noteworthy exception, according to the U.S. Department of Labor, is a claim filed with the CIA by an employee of "a self-insured contractor to the CIA that was no longer in business." The CIA advised the Department of Labor that it "had no objections" to paying the claim and Labor accepted the claim for payment: Ecological impact About 17.8% or of the total forested area of Vietnam was sprayed during the war, which disrupted the ecological equilibrium. The persistent nature of dioxins, erosion caused by loss of tree cover, and loss of seedling forest stock meant that reforestation was difficult (or impossible) in many areas. Many defoliated forest areas were quickly invaded by aggressive pioneer species (such as bamboo and cogon grass), making forest regeneration difficult and unlikely. Animal species diversity was also impacted; in one study a Harvard biologist found 24 species of birds and 5 species of mammals in a sprayed forest, while in two adjacent sections of unsprayed forest there were, respectively, 145 and 170 species of birds and 30 and 55 species of mammals. Dioxins from Agent Orange have persisted in the Vietnamese environment since the war, settling in the soil and sediment and entering the food chain through animals and fish which feed in the contaminated areas. The movement of dioxins through the food web has resulted in bioconcentration and biomagnification. The areas most heavily contaminated with dioxins are former U.S. air bases. Sociopolitical impact American policy during the Vietnam War was to destroy crops, accepting the sociopolitical impact that that would have. The RAND Corporation's Memorandum 5446-ISA/ARPA states: "the fact that the VC [the Vietcong] obtain most of their food from the neutral rural population dictates the destruction of civilian crops ... if they are to be hampered by the crop destruction program, it will be necessary to destroy large portions of the rural economy – probably 50% or more". Crops were deliberately sprayed with Agent Orange and areas were bulldozed clear of vegetation forcing many rural civilians to cities. Legal and diplomatic proceedings International The extensive environmental damage that resulted from usage of the herbicide prompted the United Nations to pass Resolution 31/72 and ratify the Environmental Modification Convention. Many states do not regard this as a complete ban on the use of herbicides and defoliants in warfare, but it does require case-by-case consideration. Article 2(4) of Protocol III of the Convention on Certain Conventional Weapons contains the "Jungle Exception", which prohibits states from attacking forests or jungles "except if such natural elements are used to cover, conceal or camouflage combatants or military objectives or are military objectives themselves". This exception voids any protection of any military and civilian personnel from a napalm attack or something like Agent Orange, and it has been argued that it was clearly designed to cover situations like U.S. tactics in Vietnam. Class action lawsuit Since at least 1978, several lawsuits have been filed against the companies which produced Agent Orange, among them Dow Chemical, Monsanto, and Diamond Shamrock. Attorney Hy Mayerson was an early pioneer in Agent Orange litigation, working with environmental attorney Victor Yannacone in 1980 on the first class-action suits against wartime manufacturers of Agent Orange. In meeting Dr. Ronald A. Codario, one of the first civilian doctors to see affected patients, Mayerson, so impressed by the fact a physician would show so much interest in a Vietnam veteran, forwarded more than a thousand pages of information on Agent Orange and the effects of dioxin on animals and humans to Codario's office the day after he was first contacted by the doctor. The corporate defendants sought to escape culpability by blaming everything on the U.S. government. In 1980, Mayerson, with Sgt. Charles E. Hartz as their principal client, filed the first U.S. Agent Orange class-action lawsuit in Pennsylvania, for the injuries military personnel in Vietnam suffered through exposure to toxic dioxins in the defoliant. Attorney Mayerson co-wrote the brief that certified the Agent Orange Product Liability action as a class action, the largest ever filed as of its filing. Hartz's deposition was one of the first ever taken in America, and the first for an Agent Orange trial, for the purpose of preserving testimony at trial, as it was understood that Hartz would not live to see the trial because of a brain tumor that began to develop while he was a member of Tiger Force, special forces, and LRRPs in Vietnam. The firm also located and supplied critical research to the veterans' lead expert, Dr. Codario, including about 100 articles from toxicology journals dating back more than a decade, as well as data about where herbicides had been sprayed, what the effects of dioxin had been on animals and humans, and every accident in factories where herbicides were produced or dioxin was a contaminant of some chemical reaction. The chemical companies involved denied that there was a link between Agent Orange and the veterans' medical problems. However, on May 7, 1984, seven chemical companies settled the class-action suit out of court just hours before jury selection was to begin. The companies agreed to pay $180 million as compensation if the veterans dropped all claims against them. Slightly over 45% of the sum was ordered to be paid by Monsanto alone. Many veterans who were victims of Agent Orange exposure were outraged the case had been settled instead of going to court and felt they had been betrayed by the lawyers. "Fairness Hearings" were held in five major American cities, where veterans and their families discussed their reactions to the settlement and condemned the actions of the lawyers and courts, demanding the case be heard before a jury of their peers. Federal Judge Jack B. Weinstein refused the appeals, claiming the settlement was "fair and just". By 1989, the veterans' fears were confirmed when it was decided how the money from the settlement would be paid out. A totally disabled Vietnam veteran would receive a maximum of $12,000 spread out over the course of 10 years. Furthermore, by accepting the settlement payments, disabled veterans would become ineligible for many state benefits that provided far more monetary support than the settlement, such as food stamps, public assistance, and government pensions. A widow of a Vietnam veteran who died of Agent Orange exposure would receive $3,700. In 2004, Monsanto spokesman Jill Montgomery said Monsanto should not be liable at all for injuries or deaths caused by Agent Orange, saying: "We are sympathetic with people who believe they have been injured and understand their concern to find the cause, but reliable scientific evidence indicates that Agent Orange is not the cause of serious long-term health effects." New Jersey Agent Orange Commission In 1980, New Jersey created the New Jersey Agent Orange Commission, the first state commission created to study its effects. The commission's research project in association with Rutgers University was called "The Pointman Project". It was disbanded by Governor Christine Todd Whitman in 1996. During the first phase of the project, commission researchers devised ways to determine trace dioxin levels in blood. Prior to this, such levels could only be found in the adipose (fat) tissue. The project studied dioxin (TCDD) levels in blood as well as in adipose tissue in a small group of Vietnam veterans who had been exposed to Agent Orange and compared them to those of a matched control group; the levels were found to be higher in the exposed group. The second phase of the project continued to examine and compare dioxin levels in various groups of Vietnam veterans, including Soldiers, Marines, and Brownwater Naval personnel. U.S. Congress In 1991, Congress enacted the Agent Orange Act, giving the Department of Veterans Affairs the authority to declare certain conditions "presumptive" to exposure to Agent Orange/dioxin, making these veterans who served in Vietnam eligible to receive treatment and compensation for these conditions. The same law required the National Academy of Sciences to periodically review the science on dioxin and herbicides used in Vietnam to inform the Secretary of Veterans Affairs about the strength of the scientific evidence showing association between exposure to Agent Orange/dioxin and certain conditions. The authority for the National Academy of Sciences reviews and addition of any new diseases to the presumptive list by the VA expired in 2015 under the sunset clause of the Agent Orange Act of 1991. Through this process, the list of 'presumptive' conditions has grown since 1991, and currently the U.S. Department of Veterans Affairs has listed prostate cancer, respiratory cancers, multiple myeloma, type II diabetes mellitus, Hodgkin's disease, non-Hodgkin's lymphoma, soft tissue sarcoma, chloracne, porphyria cutanea tarda, peripheral neuropathy, chronic lymphocytic leukemia, and spina bifida in children of veterans exposed to Agent Orange as conditions associated with exposure to the herbicide. This list now includes B cell leukemias, such as hairy cell leukemia, Parkinson's disease and ischemic heart disease, these last three having been added on August 31, 2010. Several highly placed individuals in government are voicing concerns about whether some of the diseases on the list should, in fact, actually have been included. In 2011, an appraisal of the 20-year long Air Force Health Study that began in 1982 indicates that the results of the AFHS as they pertain to Agent Orange, do not provide evidence of disease in the Operation Ranch Hand veterans caused by "their elevated levels of exposure to Agent Orange". The VA initially denied the applications of post-Vietnam C-123 aircrew veterans because as veterans without "boots on the ground" service in Vietnam, they were not covered under VA's interpretation of "exposed". In June 2015, the Secretary of Veterans Affairs issued an Interim final rule providing presumptive service connection for post-Vietnam C-123 aircrews, maintenance staff and aeromedical evacuation crews. The VA now provides medical care and disability compensation for the recognized list of Agent Orange illnesses. U.S.–Vietnamese government negotiations In 2002, Vietnam and the U.S. held a joint conference on Human Health and Environmental Impacts of Agent Orange. Following the conference, the U.S. National Institute of Environmental Health Sciences (NIEHS) began scientific exchanges between the U.S. and Vietnam, and began discussions for a joint research project on the human health impacts of Agent Orange. These negotiations broke down in 2005, when neither side could agree on the research protocol and the research project was canceled. More progress has been made on the environmental front. In 2005, the first U.S.-Vietnam workshop on remediation of dioxin was held. Starting in 2005, the EPA began to work with the Vietnamese government to measure the level of dioxin at the Da Nang Air Base. Also in 2005, the Joint Advisory Committee on Agent Orange, made up of representatives of Vietnamese and U.S. government agencies, was established. The committee has been meeting yearly to explore areas of scientific cooperation, technical assistance and environmental remediation of dioxin. A breakthrough in the diplomatic stalemate on this issue occurred as a result of United States President George W. Bush's state visit to Vietnam in November 2006. In the joint statement, President Bush and President Triet agreed "further joint efforts to address the environmental contamination near former dioxin storage sites would make a valuable contribution to the continued development of their bilateral relationship." On May 25, 2007, President Bush signed the U.S. Troop Readiness, Veterans' Care, Katrina Recovery, and Iraq Accountability Appropriations Act, 2007 into law for the wars in Iraq and Afghanistan that included an earmark of $3 million specifically for funding for programs for the remediation of dioxin 'hotspots' on former U.S. military bases, and for public health programs for the surrounding communities; some authors consider this to be completely inadequate, pointing out that the Da Nang Airbase alone will cost $14 million to clean up, and that three others are estimated to require $60 million for cleanup. The appropriation was renewed in the fiscal year 2009 and again in FY 2010. An additional $12 million was appropriated in the fiscal year 2010 in the Supplemental Appropriations Act and a total of $18.5 million appropriated for fiscal year 2011. Secretary of State Hillary Clinton stated during a visit to Hanoi in October 2010 that the U.S. government would begin work on the clean-up of dioxin contamination at the Da Nang Airbase. In June 2011, a ceremony was held at Da Nang airport to mark the start of U.S.-funded decontamination of dioxin hotspots in Vietnam. Thirty-two million dollars has so far been allocated by the U.S. Congress to fund the program. A $43 million project began in the summer of 2012, as Vietnam and the U.S. forge closer ties to boost trade and counter China's rising influence in the disputed South China Sea. Vietnamese victims class action lawsuit in U.S. courts On January 31, 2004, a victim's rights group, the Vietnam Association for Victims of Agent Orange/dioxin (VAVA), filed a lawsuit in the United States District Court for the Eastern District of New York in Brooklyn, against several U.S. companies for liability in causing personal injury, by developing, and producing the chemical, and claimed that the use of Agent Orange violated the 1907 Hague Convention on Land Warfare, 1925 Geneva Protocol, and the 1949 Geneva Conventions. Dow Chemical and Monsanto were the two largest producers of Agent Orange for the U.S. military and were named in the suit, along with the dozens of other companies (Diamond Shamrock, Uniroyal, Thompson Chemicals, Hercules, etc.). On March 10, 2005, Judge Jack B. Weinstein of the Eastern District – who had presided over the 1984 U.S. veterans class-action lawsuit – dismissed the lawsuit, ruling there was no legal basis for the plaintiffs' claims. He concluded Agent Orange was not considered a poison under international humanitarian law at the time of its use by the U.S.; the U.S. was not prohibited from using it as a herbicide; and the companies which produced the substance were not liable for the method of its use by the government. In the dismissal statement issued by Weinstein, he wrote "The prohibition extended only to gases deployed for their asphyxiating or toxic effects on man, not to herbicides designed to affect plants that may have unintended harmful side-effects on people." Author and activist George Jackson had written previously that "if the Americans were guilty of war crimes for using Agent Orange in Vietnam, then the British would be also guilty of war crimes as well since they were the first nation to deploy the use of herbicides and defoliants in warfare and used them on a large scale throughout the Malayan Emergency. Not only was there no outcry by other states in response to the United Kingdom's use, but the U.S. viewed it as establishing a precedent for the use of herbicides and defoliants in jungle warfare." The U.S. government was also not a party in the lawsuit because of sovereign immunity, and the court ruled the chemical companies, as contractors of the U.S. government, shared the same immunity. The case was appealed and heard by the Second Circuit Court of Appeals in Manhattan on June 18, 2007. Three judges on the court upheld Weinstein's ruling to dismiss the case. They ruled that, though the herbicides contained a dioxin (a known poison), they were not intended to be used as a poison on humans. Therefore, they were not considered a chemical weapon and thus not a violation of international law. A further review of the case by the entire panel of judges of the Court of Appeals also confirmed this decision. The lawyers for the Vietnamese filed a petition to the U.S. Supreme Court to hear the case. On March 2, 2009, the Supreme Court denied certiorari and declined to reconsider the ruling of the Court of Appeals. Help for those affected in Vietnam To assist those who have been affected by Agent Orange/dioxin, the Vietnamese have established "peace villages", which each host between 50 and 100 victims, giving them medical and psychological help. As of 2006, there were 11 such villages, thus granting some social protection to fewer than a thousand victims. U.S. veterans of the war in Vietnam and individuals who are aware and sympathetic to the impacts of Agent Orange have supported these programs in Vietnam. An international group of veterans from the U.S. and its allies during the Vietnam War working with their former enemy—veterans from the Vietnam Veterans Association—established the Vietnam Friendship Village outside of Hanoi. The center provides medical care, rehabilitation and vocational training for children and veterans from Vietnam who have been affected by Agent Orange. In 1998, The Vietnam Red Cross established the Vietnam Agent Orange Victims Fund to provide direct assistance to families throughout Vietnam that have been affected. In 2003, the Vietnam Association of Victims of Agent Orange (VAVA) was formed. In addition to filing the lawsuit against the chemical companies, VAVA provides medical care, rehabilitation services and financial assistance to those injured by Agent Orange. The Vietnamese government provides small monthly stipends to more than 200,000 Vietnamese believed affected by the herbicides; this totaled $40.8 million in 2008. The Vietnam Red Cross has raised more than $22 million to assist the ill or disabled, and several U.S. foundations, United Nations agencies, European governments and nongovernmental organizations have given a total of about $23 million for site cleanup, reforestation, health care and other services to those in need. Vuong Mo of the Vietnam News Agency described one of the centers: May is 13, but she knows nothing, is unable to talk fluently, nor walk with ease due to for her bandy legs. Her father is dead and she has four elder brothers, all mentally retarded ... The students are all disabled, retarded and of different ages. Teaching them is a hard job. They are of the 3rd grade but many of them find it hard to do the reading. Only a few of them can. Their pronunciation is distorted due to their twisted lips and their memory is quite short. They easily forget what they've learned ... In the Village, it is quite hard to tell the kids' exact ages. Some in their twenties have a physical statures as small as the 7- or 8-years-old. They find it difficult to feed themselves, much less have mental ability or physical capacity for work. No one can hold back the tears when seeing the heads turning round unconsciously, the bandy arms managing to push the spoon of food into the mouths with awful difficulty ... Yet they still keep smiling, singing in their great innocence, at the presence of some visitors, craving for something beautiful. On June 16, 2010, members of the U.S.-Vietnam Dialogue Group on Agent Orange/Dioxin unveiled a comprehensive 10-year Declaration and Plan of Action to address the toxic legacy of Agent Orange and other herbicides in Vietnam. The Plan of Action was released as an Aspen Institute publication and calls upon the U.S. and Vietnamese governments to join with other governments, foundations, businesses, and nonprofits in a partnership to clean up dioxin "hot spots" in Vietnam and to expand humanitarian services for people with disabilities there. On September 16, 2010, Senator Patrick Leahy acknowledged the work of the Dialogue Group by releasing a statement on the floor of the United States Senate. The statement urges the U.S. government to take the Plan of Action's recommendations into account in developing a multi-year plan of activities to address the Agent Orange/dioxin legacy. Use outside of Vietnam Australia In 2008, Australian researcher Jean Williams claimed that cancer rates in Innisfail, Queensland, were 10 times higher than the state average because of secret testing of Agent Orange by the Australian military scientists during the Vietnam War. Williams, who had won the Order of Australia medal for her research on the effects of chemicals on U.S. war veterans, based her allegations on Australian government reports found in the Australian War Memorial's archives. A former soldier, Ted Bosworth, backed up the claims, saying that he had been involved in the secret testing. Neither Williams nor Bosworth have produced verifiable evidence to support their claims. The Queensland health department determined that cancer rates in Innisfail were no higher than those in other parts of the state. Canada The U.S. military, with the permission of the Canadian government, tested herbicides, including Agent Orange, in the forests near Canadian Forces Base Gagetown in New Brunswick. In 2007, the government of Canada offered a one-time ex gratia payment of $20,000 as compensation for Agent Orange exposure at CFB Gagetown. On July 12, 2005, Merchant Law Group, on behalf of over 1,100 Canadian veterans and civilians who were living in and around CFB Gagetown, filed a lawsuit to pursue class action litigation concerning Agent Orange and Agent Purple with the Federal Court of Canada. On August 4, 2009, the case was rejected by the court, citing lack of evidence. In 2007, the Canadian government announced that a research and fact-finding program initiated in 2005 had found the base was safe. On February 17, 2011, the Toronto Star revealed that Agent Orange had been employed to clear extensive plots of Crown land in Northern Ontario. The Toronto Star reported that, "records from the 1950s, 1960s and 1970s show forestry workers, often students and junior rangers, spent weeks at a time as human markers holding red, helium-filled balloons on fishing lines while low-flying planes sprayed toxic herbicides including an infamous chemical mixture known as Agent Orange on the brush and the boys below." In response to the Toronto Star article, the Ontario provincial government launched a probe into the use of Agent Orange. Guam An analysis of chemicals present in the island's soil, together with resolutions passed by Guam's legislature, suggest that Agent Orange was among the herbicides routinely used on and around Andersen Air Force Base and Naval Air Station Agana. Despite the evidence, the Department of Defense continues to deny that Agent Orange was stored or used on Guam. Several Guam veterans have collected evidence to assist in their disability claims for direct exposure to dioxin containing herbicides such as 2,4,5-T which are similar to the illness associations and disability coverage that has become standard for those who were harmed by the same chemical contaminant of Agent Orange used in Vietnam. South Korea Agent Orange was used in South Korea in the late 1960s and in 1999, about 20,000 South Koreans filed two separated lawsuits against U.S. companies, seeking more than $5 billion in damages. After losing a decision in 2002, they filed an appeal. In January 2006, the South Korean Appeals Court ordered Dow Chemical and Monsanto to pay $62 million in compensation to about 6,800 people. The ruling acknowledged that "the defendants failed to ensure safety as the defoliants manufactured by the defendants had higher levels of dioxins than standard", and, quoting the U.S. National Academy of Science report, declared that there was a "causal relationship" between Agent Orange and a range of diseases, including several cancers. The judges failed to acknowledge "the relationship between the chemical and peripheral neuropathy, the disease most widespread among Agent Orange victims". In 2011, the United States local press KPHO-TV in Phoenix, Arizona, alleged that in 1978 that the United States Army had buried 250 55-gallon drums () of Agent Orange in Camp Carroll, the U.S. Army base located in Gyeongsangbuk-do, South Korea. Currently, veterans who provide evidence meeting VA requirements for service in Vietnam and who can medically establish that anytime after this 'presumptive exposure' they developed any medical problems on the list of presumptive diseases, may receive compensation from the VA. Certain veterans who served in South Korea and are able to prove they were assigned to certain specified around the Korean Demilitarized Zone, during a specific time frame are afforded similar presumption. New Zealand The use of Agent Orange has been controversial in New Zealand, because of the exposure of New Zealand troops in Vietnam and because of the production of herbicide used in Agent Orange which has been alleged at various times to have been exported for use in the Vietnam War and to other users by the Ivon Watkins-Dow chemical plant in Paritutu, New Plymouth. There have been continuing claims, as yet unproven, that the suburb of Paritutu has also been polluted. However, the agriscience company Corteva (which split from DowDupont in 2019) agreed to clean up the Paritutu site in September 2022. There are cases of New Zealand soldiers developing cancers such as bone cancer, but none has been scientifically connected to exposure to herbicides. Philippines Herbicide persistence studies of Agents Orange and White were conducted in the Philippines. Johnston Atoll The U.S. Air Force operation to remove Herbicide Orange from Vietnam in 1972 was named Operation Pacer IVY, while the operation to destroy the Agent Orange stored at Johnston Atoll in 1977 was named Operation Pacer HO. Operation Pacer IVY collected Agent Orange in South Vietnam and removed it in 1972 aboard the ship MV Transpacific for storage on Johnston Atoll. The EPA reports that of Herbicide Orange was stored at Johnston Island in the Pacific and at Gulfport, Mississippi. Research and studies were initiated to find a safe method to destroy the materials, and it was discovered they could be incinerated safely under special conditions of temperature and dwell time. However, these herbicides were expensive, and the Air Force wanted to resell its surplus instead of dumping it at sea. Among many methods tested, a possibility of salvaging the herbicides by reprocessing and filtering out the TCDD contaminant with carbonized (charcoaled) coconut fibers. This concept was then tested in 1976 and a pilot plant constructed at Gulfport. From July to September 1977 during Operation Pacer HO, the entire stock of Agent Orange from both Herbicide Orange storage sites at Gulfport and Johnston Atoll was subsequently incinerated in four separate burns in the vicinity of Johnston Island aboard the Dutch-owned waste incineration ship . As of 2004, some records of the storage and disposition of Agent Orange at Johnston Atoll have been associated with the historical records of Operation Red Hat. Okinawa, Japan There have been dozens of reports in the press about use and/or storage of military formulated herbicides on Okinawa that are based upon statements by former U.S. service members that had been stationed on the island, photographs, government records, and unearthed storage barrels. The U.S. Department of Defense has denied these allegations with statements by military officials and spokespersons, as well as a January 2013 report authored by Dr. Alvin Young that was released in April 2013. In particular, the 2013 report rebuts articles written by journalist Jon Mitchell as well as a statement from "An Ecological Assessment of Johnston Atoll" a 2003 publication produced by the United States Army Chemical Materials Agency that states, "in 1972, the U.S. Air Force also brought about 25,000 200L drums () of the chemical, Herbicide Orange (HO) to Johnston Island that originated from Vietnam and was stored on Okinawa." The 2013 report states: "The authors of the [2003] report were not DoD employees, nor were they likely familiar with the issues surrounding Herbicide Orange or its actual history of transport to the Island." and detailed the transport phases and routes of Agent Orange from Vietnam to Johnston Atoll, none of which included Okinawa. Further official confirmation of restricted (dioxin containing) herbicide storage on Okinawa appeared in a 1971 Fort Detrick report titled "Historical, Logistical, Political and Technical Aspects of the Herbicide/Defoliant Program", which mentions that the environmental statement should consider "Herbicide stockpiles elsewhere in PACOM (Pacific Command) U.S. Government restricted materials Thailand and Okinawa (Kadena AFB)." The 2013 DoD report says that the environmental statement urged by the 1971 report was published in 1974 as "The Department of Air Force Final Environmental Statement", and that the latter did not find Agent Orange was held in either Thailand or Okinawa. Thailand Agent Orange was tested by the United States in Thailand during the Vietnam War. In 1999, buried drums were uncovered and confirmed to be Agent Orange. Workers who uncovered the drums fell ill while upgrading the airport near Hua Hin District, 100 km south of Bangkok. Vietnam-era veterans whose service involved duty on or near the perimeters of military bases in Thailand anytime between February 28, 1961, and May 7, 1975, may have been exposed to herbicides and may qualify for VA benefits. A declassified Department of Defense report written in 1973, suggests that there was a significant use of herbicides on the fenced-in perimeters of military bases in Thailand to remove foliage that provided cover for enemy forces. In 2013, the VA determined that herbicides used on the Thailand base perimeters may have been tactical and procured from Vietnam, or a strong, commercial type resembling tactical herbicides. United States The University of Hawaii has acknowledged extensive testing of Agent Orange on behalf of the United States Department of Defense in Hawaii along with mixtures of Agent Orange on Hawaii Island in 1966 and on Kaua'i Island in 1967–1968; testing and storage in other U.S. locations has been documented by the United States Department of Veterans Affairs. In 1971, the C-123 aircraft used for spraying Agent Orange were returned to the United States and assigned various East Coast USAF Reserve squadrons, and then employed in traditional airlift missions between 1972 and 1982. In 1994, testing by the Air Force identified some former spray aircraft as "heavily contaminated" with dioxin residue. Inquiries by aircrew veterans in 2011 brought a decision by the U.S. Department of Veterans Affairs opining that not enough dioxin residue remained to injure these post-Vietnam War veterans. On 26 January 2012, the U.S. Center For Disease Control's Agency for Toxic Substances and Disease Registry challenged this with their finding that former spray aircraft were indeed contaminated and the aircrews exposed to harmful levels of dioxin. In response to veterans' concerns, the VA in February 2014 referred the C-123 issue to the Institute of Medicine for a special study, with results released on January 9, 2015. In 1978, the EPA suspended spraying of Agent Orange in national forests. Agent Orange was sprayed on thousands of acres of brush in the Tennessee Valley for 15 years before scientists discovered the herbicide was dangerous. Monroe County, Tennessee, is one of the locations known to have been sprayed according to the Tennessee Valley Authority. Forty-four remote acres were sprayed with Agent Orange along power lines throughout the National Forest. In 1983, New Jersey declared a Passaic River production site to be a state of emergency. The dioxin pollution in the Passaic River dates back to the Vietnam era, when Diamond Alkali manufactured it in a factory along the river. The tidal river carried dioxin upstream and down, contaminating a stretch of riverbed in one of New Jersey's most populous areas. A December 2006 Department of Defense report listed Agent Orange testing, storage, and disposal sites at 32 locations throughout the United States, Canada, Thailand, Puerto Rico, Korea, and in the Pacific Ocean. The Veteran Administration has also acknowledged that Agent Orange was used domestically by U.S. forces in test sites throughout the United States. Eglin Air Force Base in Florida was one of the primary testing sites throughout the 1960s. Cleanup programs In February 2012, Monsanto agreed to settle a case covering dioxin contamination around a plant in Nitro, West Virginia, that had manufactured Agent Orange. Monsanto agreed to pay up to $9 million for cleanup of affected homes, $84 million for medical monitoring of people affected, and the community's legal fees. On 9 August 2012, the United States and Vietnam began a cooperative cleaning up of the toxic chemical on part of Da Nang International Airport, marking the first time the U.S. government has been involved in cleaning up Agent Orange in Vietnam. Danang was the primary storage site of the chemical. Two other cleanup sites the United States and Vietnam are looking at is Biên Hòa, in the southern province of Đồng Nai is a hotspot for dioxin and so is Phù Cát airport in the central province of Bình Định, says U.S. Ambassador to Vietnam David Shear. According to the Vietnamese newspaper Nhân Dân, the U.S. government provided $41 million to the project. As of 2017, some of soil have been cleaned. The Seabee's Naval Construction Battalion Center at Gulfport, Mississippi was the largest storage site in the United States for agent orange. It was about in size and was still being cleaned up in 2013. In 2016, the EPA laid out its plan for cleaning up an stretch of the Passaic River in New Jersey, with an estimated cost of $1.4 billion. The contaminants reached to Newark Bay and other waterways, according to the EPA, which has designated the area a Superfund site. Since destruction of the dioxin requires high temperatures over , the destruction process is energy intensive.

Arthur Phillip (11 October 1738 – 31 August 1814) was a British Royal Navy officer who served as the first governor of the Colony of New South Wales. Phillip was educated at Greenwich Hospital School from June 1751 until December 1753. He then became an apprentice on the whaling ship Fortune. With the outbreak of the Seven Years' War against France, Phillip enlisted in the Royal Navy as captain's servant to Michael Everitt aboard . With Everitt, Phillip also served on and . Phillip was promoted to lieutenant on 7 June 1761, before being put on half-pay at the end of hostilities on 25 April 1763. Seconded to the Portuguese Navy in 1774, he served in the war against Spain. Returning to Royal Navy service in 1778, in 1782 Phillip, in command of , was to capture Spanish colonies in South America, but an armistice was concluded before he reached his destination. In 1784, Phillip was employed by Home Office Under Secretary Evan Nepean, to survey French defences in Europe. In 1786 Phillip was appointed by Lord Sydney as the commander of the First Fleet, a fleet of 11 ships whose crew were to establish a penal colony and a settlement at Botany Bay, New South Wales. On arriving at Botany Bay, Phillip found the site unsuitable and searched for a more habitable site for a settlement, which he found in Port Jackson – the site of Sydney, Australia, today. Phillip was a far-sighted governor who soon realised that New South Wales would need a civil administration and a system for emancipating convicts. However, his plan to bring skilled tradesmen on the First Fleet's voyage had been rejected. Consequently, he faced immense problems with labour, discipline, and supply. Phillip wanted harmonious relations with the local indigenous peoples, in the belief that everyone in the colony was a British citizen and was protected by the law as such, therefore the indigenous peoples had the same rights as everyone under Phillip's command. Eventually, cultural differences between the two groups of people led to conflict. The arrival of more convicts with the Second and Third Fleets placed new pressures on scarce local resources. By the time Phillip sailed home in December 1792, the colony was taking shape, with official land grants, systematic farming, and a water supply in place. On 11 December 1792, Phillip left the colony to return to Britain to receive medical treatment for kidney stones. He had planned to return to Australia, but medical advisors recommended he resign from the governorship. His health recovered and he returned to active duty in the Navy in 1796, holding a number of commands in home waters before being put in command of the Hampshire Sea Fencibles. He eventually retired from active naval service in 1805. He spent his final years of retirement in Bath, Somerset, before his death on 31 August 1814. As the first Governor of New South Wales, a number of places in Australia are named after him, including Port Phillip, Phillip Island, Phillip Street in Sydney, the suburb of Phillip in Canberra and the Governor Phillip Tower building in Sydney, as well as many streets, parks, and schools. Early life Arthur Phillip was born on 11 October 1738, in the Parish of All Hallows, in Bread Street, London. He was the son of Jacob Phillip, an immigrant from Frankfurt, who by various accounts was a language teacher, a merchant vessel owner, a merchant captain, or a common seaman. His mother, Elizabeth Breach, was the widow of a common seaman by the name of John Herbert, who had died of disease in Jamaica aboard on 13 August 1732. At the time of Arthur Phillip's birth, his family maintained a modest existence as tenants near Cheapside in the City of London. There are no surviving records of Phillip's early childhood. His father, Jacob, died in 1739, after which the Phillip family would have a low income. Arthur went to sea on a British naval vessel aged nine. On 22 June 1751, he was accepted into the Greenwich Hospital School, a charity school for the sons of indigent seafarers. In accordance with the school's curriculum, his education focused on literacy, arithmetic, and navigational skills, including cartography. His headmaster, Reverend Francis Swinden, observed that in personality, Phillip was "unassuming, reasonable, business-like to the smallest degree in everything he undertakes". Phillip remained at the Greenwich Hospital School for two and a half years, longer than the average student stay of one year. At the end of 1753, he was granted a seven-year indenture as an apprentice aboard Fortune, a 210-ton whaling vessel commanded by merchant mariner William Readhead. Phillip left the Greenwich Hospital School on 1 December, and spent the next few months aboard the Fortune, awaiting the start of the 1754 whaling season. Contemporary portraits depict Phillip as shorter than average, with an olive complexion and dark eyes. A long nose and a pronounced lower lip dominated his "smooth pear of a skull" as quoted by Robert Hughes. Early maritime career Whaling and merchant expeditions In April 1754 Fortune headed out to hunt whales near Svalbard in the Barents Sea. As an apprentice Phillip's responsibilities included stripping blubber from whale carcasses and helping to pack it into barrels. Food was scarce, and Fortunes 30 crew members supplemented their diet with bird's eggs, scurvy grass, and, where possible, reindeer. The ship returned to England on 20 July 1754. The whaling crew were paid and replaced with twelve sailors for a winter voyage to the Mediterranean. Phillip remained aboard as Fortune undertook an outward trading voyage to Barcelona and Livorno carrying salt and raisins, returning via Rotterdam with a cargo of grains and citrus. The ship returned to England in April 1755 and sailed immediately for Svalbard for that year's whale hunt. Phillip was still a member of the crew but abandoned his apprenticeship when the ship returned to England on 27 July. Royal Navy and the Seven Years' War On 16 October 1755, Phillip enlisted in the Royal Navy as captain's servant aboard the 68-gun , commanded by his mother's cousin, Captain Michael Everitt. As a member of Buckinghams crew, Phillip served in home waters until April 1756 and then joined Admiral John Byng's Mediterranean fleet. The Buckingham was Rear-Admiral Temple West's flagship at the Battle of Minorca on 20 May 1756. Phillip moved on 1 August 1757, with Everitt, to the 90-gun , which took part in the Raid on St Malo on 5–12 June 1758. Phillip, again with Captain Everitt, transferred on 28 December 1758 to the 64-gun , which went to the West Indies to serve at the Siege of Havana. On 7 June 1761, Phillip was commissioned as a lieutenant in recognition for his active service. With the coming of peace on 25 April 1763, he was retired on half-pay. Retirement and the Portuguese Navy In July 1763, Phillip married Margaret Charlotte Denison (), known as Charlott, a widow 16 years his senior, and moved to Glasshayes in Lyndhurst, Hampshire, establishing a farm there. The marriage was unhappy, and the couple separated in 1769 when Phillip returned to the Navy. The following year, he was posted as second lieutenant aboard , a newly built 74-gun ship of the line. In 1774, Phillip was seconded to the Portuguese Navy as a captain, serving in the war against Spain. While with the Portuguese Navy, Phillip commanded a 26-gun frigate, Nossa Senhora do Pilar. On that ship, he took a detachment of troops from Rio de Janeiro to Colonia do Sacramento on the Río de la Plata (opposite Buenos Aires) to relieve the garrison there. The voyage also conveyed a consignment of convicts assigned to carry out work at Colonia. During a storm encountered in the course of the voyage, the convicts assisted in working the ship, and on arriving at Colonia, Phillip recommended that they be rewarded for saving the ship by remission of their sentences. A garbled version of this recommendation eventually found its way into the English press in 1786, when Phillip was appointed to lead the expedition to Sydney. Phillip played a leading role in the capture of the Spanish ship San Agustín, on 19 April 1777, off Santa Catarina. The Portuguese Navy commissioned her as the Santo Agostinho, under Phillip's command. The action was reported in the English press: Madrid, 28 Aug. Letters from Lisbon bring the following Account from Rio Janeiro: That the St. Augustine, of 70 Guns, having been separated from the Squadron of M. Casa Tilly, was attacked by two Portugueze Ships, against which they defended themselves for a Day and a Night, but being next Day surrounded by the Portugueze Fleet, was obliged to surrender. Recommissioned into Royal Navy In 1778, with Britain again at war, Phillip was recalled to Royal Navy service and on 9 October was appointed first lieutenant of the 74-gun as part of the Channel fleet. Promoted to commander on 2 September 1779 and given command of the 8-gun fireship HMS Basilisk. With Spain's entry into the conflict, Phillip had a series of private meetings with the First Lord of the Admiralty, the Earl of Sandwich, sharing his charts and knowledge about the South American coastlines. Phillip was promoted to post-captain on 30 November 1781 and given command of the 20-gun . Ariadne was sent to the Elbe to escort a transport ship carrying a detachment of Hanoverian troops, arriving at the port of Cuxhaven on 28 December, the estuary froze over trapping Ariadne in the harbour. In March 1782, Phillip arrived in England with the Hanoverian troops. In the following months Ariadne got a new lieutenant, Philip Gidley King, whom Phillip took under his wing. Ariadne was used to patrol the Channel where on 30 June, she captured the French frigate Le Robecq. With a change of government on 27 March 1782, Sandwich retired from the Admiralty, Lord Germain was replaced as Secretary of State for Home and American Affairs by Earl of Shelburne, before 10 July 1782, in another change of government Thomas Townshend replaced him, and assumed responsibility for organising an expedition against Spanish America. Like Sandwich and Germain, he turned to Phillip for planning advice. The plan was for a squadron of three ships of the line and a frigate to mount a raid on Buenos Aires and Monte Video, then to proceed to the coasts of Chile, Peru, and Mexico to maraud, and ultimately to cross the Pacific to join the British Navy's East India squadron for an attack on Manila. On 27 December 1782, Phillip, took charge of the 64-gun . The expedition, consisting of the 70-gun , the 74-gun , Europa, and the 32-gun frigate , sailed on 16 January 1783 under the command of Commodore Robert Kingsmill. Shortly after the ships' departure, an armistice was concluded between Great Britain and Spain. Phillip learnt of this in April when he put in for storm repairs at Rio de Janeiro. Phillip wrote to Townshend from Rio de Janeiro on 25 April 1783, expressing his disappointment that the ending of the American War had robbed him of the opportunity for naval glory in South America. Survey work in Europe After his return to England in April 1784, Phillip remained in close contact with Townshend, now Lord Sydney, and Home Office Under Secretary Evan Nepean. From October 1784 to September 1786, Nepean, who was in charge of the Secret Service relating to the Bourbon Powers, France, and Spain, employed him to spy on the French naval arsenals at Toulon and other ports. There was fear that Britain would soon be at war with these powers as a consequence of the Batavian Revolution in the Netherlands. Colonial service Lord Sandwich, together with the president of the Royal Society, Sir Joseph Banks, the scientist who had accompanied Lieutenant James Cook on his 1770 voyage, was advocating the establishment of a British colony in Botany Bay, New South Wales. Banks accepted an offer of assistance from the American loyalist James Matra in July 1783. Under Banks' guidance, Matra rapidly produced "A Proposal for Establishing a Settlement in New South Wales" (24 August 1783), with a fully developed set of reasons for a colony composed of American loyalists, Chinese, and South Sea Islanders (but not convicts). Thomas Townshend, Lord Sydney, as Secretary of State for the Home Office and minister in charge, decided to establish the proposed colony in Australia. This decision was taken for two reasons: the ending of the option to transport criminals to North America following the American Revolution, and the need for a base in the Pacific to counter French expansion. In September 1786, Phillip was appointed commodore of the fleet, which came to be known as the First Fleet. His assignment was to transport convicts and soldiers to establish a colony at Botany Bay. Upon arriving there, Phillip was to assume the powers of captain general and governor in chief of the new colony. A subsidiary colony was to be founded on Norfolk Island, as recommended by Sir John Call and Sir George Young, to take advantage of that island's native flax (harakeke) and timber for naval purposes. Voyage to Colony of New South Wales On 25 October 1786, the 20-gun , lying in the dock at Deptford, was commissioned, with the command given to Phillip. The armed tender , under the command of Lieutenant Henry Lidgbird Ball, was also commissioned to join the expedition. On 15 December, Captain John Hunter was assigned as second captain to Sirius to command in the absence of Phillip, who as governor of the colony, would be where the seat of government was to be fixed. Phillip had a difficult time assembling the fleet, which was to make an eight-month sea voyage and then establish a colony. Everything a new colony might need had to be taken, since Phillip had no real idea of what he might find when he got there. There were few funds available for equipping the expedition. His suggestion that people with experience in farming, building, and crafts be included was rejected by the Home Office. Most of the 772 convicts were petty thieves from the London slums. A contingent of marines and a handful of other officers who were to administer the colony accompanied Phillip. The fleet of 11 ships and about 1,500 people, under Phillip's command, sailed from Portsmouth, England, on 13 May 1787; provided an escort out of British waters. On 3 June 1787, the fleet anchored at Santa Cruz, Tenerife. On 10 June they set sail to cross the Atlantic to Rio de Janeiro, taking advantage of favourable trade winds and ocean currents. The Fleet reached Rio de Janeiro on 5 August and stayed for a month to resupply. The Fleet left Rio de Janeiro on 4 September to run before the westerlies to Table Bay in Southern Africa, which it reached on 13 October; this was the last port of call before Botany Bay. On 25 November, Phillip transferred from the Sirius to the faster Supply, and with the faster ships of the fleet hastened ahead to prepare for the arrival of the rest of the fleet. However, this "flying squadron", as Frost called it, reached Botany Bay only hours before the rest of the Fleet, so no preparatory work was possible. Supply reached Botany Bay on 18 January 1788; the three fastest transports in the advance group arrived on 19 January; slower ships, including Sirius, arrived on 20 January. Phillip soon decided that the site, chosen on the recommendation of Sir Joseph Banks, who had accompanied James Cook in 1770, was not suitable, since it had poor soil, no secure anchorage, and no reliable water source. Cook was an explorer and Banks had a scientific interest, whereas Phillip's differing assessment of the site came from his perspective as, quoted by Tyrrell, "custodian of over a thousand convicts" for whom he was responsible. After some exploration, Phillip decided to go on to Port Jackson, and on 26 January, the marines and the convicts landed at a cove, which Phillip named for Lord Sydney. This date later became Australia's national day, Australia Day. Governor Phillip formally proclaimed the colony on 7 February 1788 in Sydney. Sydney Cove offered a fresh water supply and a safe harbour, which Phillip famously described as: "being with out exception the finest Harbour in the World [...] Here a Thousand Sail of the Line may ride in the most perfect Security." Establishing a settlement On 26 January, the Union Jack was raised, and possession of the land was taken formally in the name of King George III. The next day, sailors from Sirius, a party of marines, and a number of male convicts were disembarked to fell timber and clear the ground for the erection of tents. The remaining large company of male convicts disembarked from the transports over the following days. Phillip himself structured the ordering of the camp. His own tent as governor and those of his attendant staff and servants were set on the east side of Tank Stream, with the tents of the male convicts and marines on the west. During this time, priority was given to building permanent storehouses for the settlement's provisions. On 29 January, the governor's portable house was placed, and livestock were landed the next day. The female convicts disembarked on 6 February; the general camp for the women was to the north of the governor's house and separated from the male convicts by the houses of chaplain Richard Johnson and the Judge Advocate, Marine Captain David Collins. On 7 February 1788, Phillip and his government were formally inaugurated. On 15 February 1788, Phillip sent Lieutenant Philip Gidley King with a party of 23, including 15 convicts, to establish the colony at Norfolk Island, partly in response to a perceived threat of losing the island to the French, and partly to establish an alternative food source for the mainland colony. Governor of New South Wales When Phillip was appointed as governor-designate of the colony and began to plan the expedition, he requested that the convicts that were being sent be trained; only twelve carpenters and a few men who knew anything about agriculture were sent. Seamen with technical and building skills were commandeered immediately. The colony's isolation meant that it took almost two years for Phillip to receive replies to his dispatches from his superiors in London. Phillip established a civil administration, with courts of law, that applied to everyone living in the settlement. Two convicts, Henry and Susannah Kable, sought to sue Duncan Sinclair, the captain of the Alexander, for stealing their possessions during the voyage. Sinclair, believing that as convicts they had no protection from the law, as was the case in Britain, boasted that he could not be sued. Despite this, the court found for the plaintiffs and ordered the captain to make restitution for the theft of the Kables' possessions. Phillip had drawn up a detailed memorandum of his plans for the proposed new colony. In one paragraph he wrote: "The laws of this country [England] will of course, be introduced in [New] South Wales, and there is one that I would wish to take place from the moment his Majesty's forces take possession of the country: That there can be no slavery in a free land, and consequently no slaves." Nevertheless, Phillip believed in severe discipline; floggings and hangings were commonplace, although Phillip commuted many death sentences. The settlement's supplies were rationed equally to convicts, officers, and marines, and females were given two-thirds of the weekly males' rations. In late February, six convicts were brought before the criminal court for stealing supplies. They were sentenced to death; the ringleader, Thomas Barrett, was hanged that day. Phillip gave the rest a reprieve. They were banished to an island in the harbour and given only bread and water. The governor also expanded the settlement's knowledge of the landscape. Two officers from Sirius, Captain John Hunter and Lieutenant William Bradley, conducted a thorough survey of the harbour at Sydney Cove. Phillip later joined them on an expedition to survey Broken Bay. The fleet's ships left over the next months, with Sirius and Supply remaining in the colony under command of the governor. They were used to survey and map the coastlines and waterways. Scurvy broke out, so Sirius left Port Jackson for Cape Town under the command of Hunter in October 1788, having been sent for supplies. The voyage, which completed a circumnavigation, returned to Sydney Cove in April, just in time to save the near-starving colony. As an experienced farmhand, Phillip's appointed servant Henry Edward Dodd, served as farm superintendent at Farm Cove, where he successfully cultivated the first crops, later moving to Rose Hill, where the soil was better. James Ruse, a convict, was later appointed to the position after Dodd died in 1791. When Ruse succeeded in the farming endeavours, he received the colony's first land grant. In June 1790, more convicts arrived with the Second Fleet, but , carrying more supplies, was disabled en route after hitting an iceberg, leaving the colony low on provisions again. Supply, the only ship left under colonial command after Sirius was wrecked 19 March 1790 trying to land men and supplies on Norfolk Island, was sent to Batavia for supplies. In late 1792, Phillip, whose health was suffering, relinquished the governorship to Major Francis Grose, lieutenant-governor and commander of New South Wales Corps. On 11 December 1792, Phillip left for Britain, on the Atlantic, which had arrived with convicts of the Third Fleet. Phillip was unable to follow his original intention of returning to Port Jackson once his health was restored, as medical advice compelled him to resign formally on 23 July 1793. Military personnel in colony The main challenge for order and harmony in the settlement came not from the convicts secured there on terms of good behaviour, but from the attitude of officers from the New South Wales Marine Corps. As Commander in Chief, Phillip was in command of both the naval and marine forces; his naval officers readily obeyed his commands, but a measure of co-operation from the marine officers ran against their tradition. Major Robert Ross and his officers (with the exception of a few such as David Collins, Watkin Tench, and William Dawes) refused to do anything other than guard duty, claiming that they were neither gaolers, supervisors, nor policemen. Four companies of marines, consisting of 160 privates with 52 officers and NCO's, accompanied the First Fleet to Botany Bay. In addition, there were 34 officers and men serving in the Ship's Complement of Marines aboard Sirius and Supply, bringing the total to 246 who departed England. Ross supported and encouraged his fellow officers in their conflicts with Phillip, engaged in clashes of his own, and complained of the governor's actions to the Home Office. Phillip, more placid and forbearing in temperament, was anxious in the interests of the community as a whole to avoid friction between the civil and military authorities. Though firm in his attitude, he endeavoured to placate Ross, but to little effect. In the end, he solved the problem by ordering Ross to Norfolk Island on 5 March 1790 to replace the commandant there. Beginning with guards arriving with the Second and Third fleets, but officially with the arrival of on 22 September 1791, the New South Wales Marines were relieved by a newly formed British Army regiment of foot, the New South Wales Corps. On 18 December 1791, Gorgon left Port Jackson, taking home the larger part of the still-serving New South Wales Marines. There remained in New South Wales a company of active marines serving under Captain George Johnston, who had been Phillip's aide-de-camp, that transferred to the New South Wales Corps. Also remaining in the colony were discharged marines, many of whom became settlers. The official departure of the last serving marines from the colony was in December 1792, with Governor Phillip on Atlantic. Major Francis Grose, commander of the New South Wales Corps, had replaced Ross as the Lieutenant-Governor and took over command of the colony when Phillip returned to Britain. Relations with indigenous peoples Phillip's official orders with regard to Aboriginal people were to "conciliate their affections", to "live in amity and kindness with them", and to punish anyone who should "wantonly destroy them, or give them any unnecessary interruption in the exercise of their several occupations". The first meeting between the colonists and the Eora, Aboriginal people, happened in Botany Bay. When Phillip went ashore, gifts were exchanged, thus Phillip and the officers began their relationship with the Eora through gift-giving, hilarity, and dancing, but also by showing them what their guns could do. Anyone found harming or killing Aboriginal people without provocation would be severely punished. After the early meetings, dancing, and musket demonstrations, the Eora avoided the settlement in Sydney Cove for the first year, but they warned and then attacked whenever colonists trespassed on their lands away from the settlement. Part of Phillip's early plan for peaceful cohabitation had been to persuade some Eora, preferably a family, to come and live in the town with the British so that the colonists could learn about the Eora's language, beliefs, and customs. By the end of the first year, as none of the Eora had come to live in the settlement, Phillip decided on a more ruthless strategy, and ordered the capture of some Eora warriors. The man who was captured was Arabanoo, from whom Phillip and his officers started to learn language and customs. Arabanoo died in April 1789 of smallpox, which also ravaged the rest of the Eora population. Phillip again ordered the boats to Manly Cove, where two more warriors were captured, Coleby and Bennelong; Coleby soon escaped, but Bennelong remained. Bennelong and Phillip formed a kind of friendship, before he too escaped. Four months after Bennelong escaped from Sydney, Phillip was invited to a whale feast at Manly. Bennelong greeted him in a friendly and jovial way. Phillip was suddenly surrounded by warriors and speared in the shoulder by a man called Willemering. He ordered his men not to retaliate. Phillip, perhaps realising that the spearing was in retaliation for the kidnapping, ordered no actions to be taken over it. Friendly relations were reestablished afterwards, with Bennelong even returning to Sydney with his family. Even though there were now friendly relations with the Indigenous people around Sydney Cove, the same couldn't be said about the ones around Botany Bay, who had killed or wounded 17 colonists. Phillip despatched orders, as quoted by Tench, "to put to death ten... [and] cut off the heads of the slain... to infuse a universal terror, which might operate to prevent further mischief". Even though two expeditions were despatched under command of Watkin Tench, no one was apprehended. On 11 December 1792, when Phillip returned to Britain, Bennelong and another Aboriginal man named Yemmerrawanne (or Imeerawanyee) travelled with him on the Atlantic. Later life and death Phillip's estranged wife, Charlott, died 3 August 1792 and was buried in St Beuno's Churchyard, Llanycil, Bala, Merionethshire. Phillip, a resident in Marylebone, married Isabella Whitehead of Bath in St Marylebone Church of England on 8 May 1794. His health recovered, he was recommissioned in March 1796 to the 74-gun as part of the Channel fleet. In October, his command was switched to the 74-gun . In September 1797, Phillip was transferred again to the 90-gun , command of which he held until December of that year. During 1798–99, Phillip commanded the Hampshire Sea Fencibles, then appointed inspector of the Impress Service, in which capacity he and a secretary toured the outposts of Britain to report on the strengths of the various posts. In the ordinary course of events he was promoted to Rear-Admiral on 1 January 1801. Phillip retired in 1805 from active service in the Navy, was promoted to Vice-Admiral on 13 December 1806, and received a final promotion to Admiral of the Blue on 4 June 1814. Phillip suffered a stroke in 1808, which left him partially paralysed. He died 31 August 1814 at his residence, 19 Bennett Street, Bath. He was buried nearby at St Nicholas's Church, Bathampton. His Last Will and Testament has been transcribed and is online. Forgotten for many years, the grave was discovered in November 1897 by a young woman cleaning the church, who found the name after lifting matting from the floor; the historian James Bonwick had been searching Bath records for its location. An annual service of remembrance is held at the church around Phillip's birthdate by the Britain–Australia Society. In 2007, Geoffrey Robertson QC alleged that Phillip's remains were no longer in St Nicholas Church, Bathampton, and had been lost: "Captain Arthur Phillip is not where the ledger stone says he is: it may be that he is buried somewhere outside, it may simply be that he is simply lost. But he is not where Australians have been led to believe that he now lies." Legacy A number of places in Australia bear Phillip's name, including Port Phillip, Phillip Island (Victoria), Phillip Island (Norfolk Island), Phillip Street in Sydney, the federal electorate of Phillip (1949–1993), the suburb of Phillip in Canberra, the Governor Phillip Tower building in Sydney, St Phillip's Church, Sydney (now St Philip's), and many streets, parks, and schools, including a state high school in Parramatta. A monument to Phillip in Bath Abbey Church was unveiled in 1937. Another was unveiled at St Mildred's Church, Bread Street, London, in 1932; that church was destroyed in the London Blitz in 1940, but the principal elements of the monument were re-erected at the west end of Watling Street, near Saint Paul's Cathedral, in 1968. A different bust and memorial is inside the nearby church of St Mary-le-Bow. There is a statue of him in the Royal Botanical Gardens, Sydney. There is a portrait of him by Francis Wheatley in the National Portrait Gallery, London, and in the Mitchell Library, State Library of New South Wales, Sydney. Percival Serle wrote of Phillip in his Dictionary of Australian Biography: 200th anniversary As part of a series of events on the bicentenary of his death, a memorial was dedicated in Westminster Abbey on 9 July 2014. In the service, the Dean of Westminster, Very Reverend Dr John Hall, described Phillip as follows: "This modest, yet world-class seaman, linguist, and patriot, whose selfless service laid the secure foundations on which was developed the Commonwealth of Australia, will always be remembered and honoured alongside other pioneers and inventors here in the Nave: David Livingstone, Thomas Cochrane, and Isaac Newton." A similar memorial was unveiled by the outgoing 37th Governor of New South Wales, Marie Bashir, in St James' Church, Sydney, on 31 August 2014. A bronze bust was installed at the Museum of Sydney, and a full-day symposium discussed his contributions to the founding of modern Australia. In popular culture Phillip has been played by a number of actors in movies and television programs, including: Sir Cedric Hardwicke in Botany Bay (1953) Edward Hepple in The Hungry Ones (1963) Wynn Roberts in Prelude to Harvest (1963) Sam Neill in The Incredible Journey of Mary Bryant (2005) David Wenham in Banished (2015) He is a prominent character in Timberlake Wertenbaker's play Our Country's Good, in which he commissions Lieutenant Ralph Clark to stage a production of The Recruiting Officer. He is shown as compassionate and just, but receives little support from his fellow officers. His life was dramatised on radio in I'll Meet You in Botany Bay (1945).

André René Roussimoff (; 19 May 1946 – 28 January 1993), better known by his ring name André the Giant, was a French professional wrestler and actor. Known as "the Eighth Wonder of the World," Roussimoff was known for his great size, which was a result of gigantism caused by excess growth hormones. Beginning his career in 1966, Roussimoff relocated to North America in 1971. From 1973 to the mid-1980s, Roussimoff was booked by World Wide Wrestling Federation (WWWF) promoter Vincent J. McMahon as a roving "special attraction" who wrestled for promotions throughout the United States, as well as in Japan for New Japan Pro-Wrestling. During the 1980s wrestling boom, Roussimoff became a mainstay of the WWWF (by then renamed the World Wrestling Federation), being paired with the villainous manager Bobby Heenan and feuding with Hulk Hogan. The two headlined WrestleMania III in 1987, and in 1988, he defeated Hogan to win the WWF Championship, his sole world heavyweight championship, on the first episode of The Main Event. As his WWF career wound down after WrestleMania VI in 1990, Roussimoff wrestled primarily for All Japan Pro-Wrestling, usually alongside Giant Baba, until his sudden death. After his death in 1993, Roussimoff became the inaugural inductee into the newly created WWF Hall of Fame. He was later a charter member of the Wrestling Observer Newsletter Hall of Fame and the Professional Wrestling Hall of Fame; the latter describes him as being "one of the most recognizable figures in the world both as a professional wrestler and as a pop culture icon." Outside of wrestling, Roussimoff is best known for appearing as Fezzik, the giant in the 1987 film The Princess Bride. Early life André René Roussimoff was born on 19 May 1946 in Coulommiers, Seine-et-Marne, the son of immigrants Boris Roussimoff (1907–1993) and Mariann Roussimoff Stoeff (1910–1997); his father was Bulgarian and his mother was Polish. He was raised Catholic. He had two older siblings and two younger. His childhood nickname was Dédé (, ). At birth, André weighed ; as a child, he displayed symptoms of gigantism, and was noted as "a good head taller than other kids", with abnormally long hands. In a 1970s television interview, Roussimoff stated that his mother was tall and his father tall, and that according to his father his grandfather was tall. By the time he was 12, Roussimoff stood . Roussimoff was an average student, though good at mathematics. After finishing school at 14, as he did not think higher education was necessary for a farm laborer, he joined the workforce; contrary to popular legend, he did not drop out of school, as compulsory education in France at the time ended at 14. Roussimoff spent years working on his father's farm in Molien, where, according to his brother Jacques, he could perform the work of three men. He also completed an apprenticeship in woodworking, and next worked in a factory that manufactured engines for hay balers. None of these brought him any satisfaction. While Roussimoff was growing up in the 1950s, the Irish playwright Samuel Beckett was one of several adults who sometimes drove local children to school, including Roussimoff and his siblings. They had a surprising amount of common ground and bonded over their love of cricket, with Roussimoff recalling that the two rarely talked about anything else. Professional wrestling career Early career (1964–1971) At the age of 18, Roussimoff moved to Paris and was taught professional wrestling by a local promoter, Robert Lageat, who recognized the earning potential of Roussimoff's size. He trained at night and worked as a mover during the day to pay living expenses. Roussimoff was billed as "Géant Ferré", a name based on the Picardian folk hero Grand Ferré, and began wrestling in Paris and nearby areas. Canadian promoter and wrestler Frank Valois met Roussimoff in 1966, years later to become his business manager and adviser. Roussimoff began making a name for himself wrestling in the United Kingdom, Germany, Australia, New Zealand, and Africa. He made his Japanese debut for the International Wrestling Enterprise in 1970, billed as "Monster Roussimoff". Wrestling as both a singles and tag team competitor, he quickly was made the IWA World Tag Team Champion alongside Michael Nador. During his time in Japan, doctors first informed Roussimoff that he suffered from acromegaly. Roussimoff next moved to Montreal, Canada in 1971, where he became an immediate success, regularly selling out the Montreal Forum. Promoters eventually ran out of plausible opponents for him and, as the novelty of his size wore off, the gate receipts dwindled. Roussimoff was defeated by Adnan Al-Kaissie in Baghdad in 1971, and wrestled numerous times in 1971 for Verne Gagne's American Wrestling Association (AWA) as a special attraction. Touring special attraction (1971–1984) In 1973, Vincent J. McMahon, founder of the World Wide Wrestling Federation (WWWF), suggested several changes to Roussimoff's booking and presentation. He felt Roussimoff should be portrayed as a large, immovable monster, and to enhance the perception of his size, McMahon discouraged Roussimoff from performing maneuvers such as dropkicks (although he was capable of performing such agile maneuvers before his health deteriorated in later life). He also began billing Roussimoff as "André the Giant" and set up a travel-intensive schedule, lending him to wrestling associations around the world, to keep him from becoming overexposed in any area. Promoters had to guarantee Roussimoff a certain amount of money as well as pay McMahon's WWF booking fee. On 24 March 1973, Roussimoff debuted in the World Wide Wrestling Federation (later World Wrestling Federation) as a fan favorite, defeating Frank Valois and Bull Pometti in a handicap match in Philadelphia. Two days later he made his debut in New York's Madison Square Garden, defeating Buddy Wolfe. Roussimoff was one of professional wrestling's most beloved babyfaces throughout the 1970s and early 1980s. As such, Gorilla Monsoon often stated that Roussimoff had not been defeated in 15 years by pinfall or submission prior to WrestleMania III. He had lost matches outside of the WWF: a loss to Adnan Al-Kaissie in Baghdad, Iraq in 1971, pinfall losses to Don Leo Jonathan in Montreal in 1972, Killer Kowalski in Quebec City in 1972 two draws and a countout loss to The Sheik in Toronto in 1974 after a fireball was thrown in Andre's face, knockout to Jerry Lawler in Memphis in 1975 and a count out to Lawler in Louisville in 1977, draw with Bobo Brazil at a battle royal in Detroit in 1976, Ronnie Garvin in Knoxville in 1978, Stan Hansen by disqualification in Japan in 1981, Kamala by countout in Toronto in 1984 and Canek in Mexico in 1984 and submission losses in Japan to Strong Kobayashi in 1972 and Antonio Inoki in 1986. He also had sixty-minute time-limit draws with two of the three major world champions of the day, Harley Race in Houston in 1979 and Nick Bockwinkel in Chicago in 1976. In 1976, at the second Showdown at Shea, Roussimoff fought professional boxer Chuck Wepner in an unscripted boxer-versus-wrestler fight. The wild fight was shown via telecast as part of the undercard of the Muhammad Ali versus Antonio Inoki fight and ended when he threw Wepner over the top rope and outside the ring and won via count-out. In 1980, he feuded with Hulk Hogan, when, unlike their more famous matches in the late 1980s, Hogan was the villain and Roussimoff was the hero, wrestling him at Shea Stadium's third Showdown at Shea event and in Pennsylvania, where after Roussimoff pinned Hogan to win the match, Hogan bodyslammed him much like their legendary WrestleMania III match in 1987. The feud continued in Japan in 1982 and 1983 with their roles reversed and with Antonio Inoki also involved. One of Roussimoff's feuds pitted him against the "Mongolian Giant" Killer Khan. According to the storyline, Khan snapped Roussimoff's ankle during a match on 2 May 1981 in Rochester, New York by leaping off the top rope and crashing down upon it with his knee-drop. In reality, he had broken his ankle getting out of bed the morning before the match. The injury and subsequent rehabilitation was worked into the existing Roussimoff/Khan storyline. After a stay at Beth Israel Hospital in Boston, Roussimoff returned with payback on his mind. The two battled on 20 July 1981, at Madison Square Garden in a match that resulted in a double disqualification. Their feud continued as fans filled arenas up and down the east coast to witness their matches. On 14 November 1981 at the Philadelphia Spectrum, he decisively defeated Khan in what was billed as a "Mongolian stretcher match", in which the loser must be taken to the dressing room on a stretcher. The same type of match was also held in Toronto. In early 1982 the two also fought in a series of matches in Japan with Arnold Skaaland in Roussimoff's corner. World Wrestling Federation (1984–1991) Feud with the Heenan Family (1984–1987) In 1982, Vincent J. McMahon sold the World Wide Wrestling Federation to his son, Vince McMahon As McMahon began to expand his newly acquired promotion to the national level, he required his wrestlers to appear exclusively for him. McMahon signed Roussimoff to these terms in 1984, although he still allowed him to work in Japan for New Japan Pro-Wrestling (NJPW). Roussimoff feuded with Big John Studd over which of the two men was the "true giant" of wrestling. Throughout the early to mid-1980s, Roussimoff and Studd fought all over the world, battling to try to determine who the real giant of wrestling was. In 1984, Studd took the feud to a new level when he and partner Ken Patera knocked out Roussimoff during a televised tag-team match and proceeded to cut off his hair. After gaining revenge on Patera, Roussimoff met Studd in a "body slam challenge" at the first WrestleMania, held 31 March 1985, at Madison Square Garden in New York City. Roussimoff slammed Studd to win the match and collect the $15,000 prize, then proceeded to throw cash to the fans before having the bag taken from him by Studd's manager, Bobby "The Brain" Heenan. At WrestleMania 2 on 7 April 1986, Roussimoff continued to display his dominance by winning a twenty-man battle royal which featured top National Football League stars and wrestlers. He last eliminated Bret Hart to win the contest. Following a final tour with New Japan Pro-Wrestling in mid-1986, and a win in Austria over CWA World champion Otto Wanz, Roussimoff began appearing exclusively with the World Wrestling Federation. After WrestleMania 2, Roussimoff continued his feud with Studd and King Kong Bundy. Around this time, Roussimoff requested a leave of absence to tend to his health, since the effects from his acromegaly were beginning to take their toll, as well as to tour Japan. He had also been cast in the film The Princess Bride. To explain his absence, a storyline was developed in which Heenan—suggesting that Roussimoff was secretly afraid of Studd and Bundy, whom Heenan bragged were unbeatable—challenged Roussimoff and a partner of his choosing to wrestle Studd and Bundy in a televised tag-team match. When Roussimoff failed to show, WWF president Jack Tunney indefinitely suspended him. Later in the summer of 1986, upon Roussimoff's return to the United States, he began wearing a mask and competing as the "Giant Machine" in a stable known as the Machines. Big Machine and Super Machine were the other members; Hulk Hogan (as "Hulk Machine") and Roddy Piper (as "Piper Machine") were also one-time members. The WWF's television announcers sold the Machines—a gimmick that was copied from the New Japan Pro-Wrestling character "Super Strong Machine", played by Japanese wrestler Junji Hirata, —as "a new tag-team from Japan" and claimed not to know the identities of the wrestlers, even though it was obvious to fans that it was Roussimoff competing as the Giant Machine. Heenan, Studd, and Bundy complained to Tunney, who eventually told Heenan that if it could be proven that Roussimoff and the Giant Machine were the same person, Roussimoff would be fired. Roussimoff thwarted Heenan, Studd, and Bundy at every turn. Then, in late 1986, the Giant Machine "disappeared" and Roussimoff was reinstated. Foreshadowing Roussimoff's heel turn, Heenan expressed his approval of the reinstatement but did not explain why. Alliance with Bobby Heenan and Ted DiBiase (1987–1989) Roussimoff agreed to turn heel in early 1987 to be the counter to the biggest "babyface" in professional wrestling at that time, Hulk Hogan. On an edition of Piper's Pit in 1987, Hogan was presented a trophy for being the WWF World Heavyweight Champion for three years; Roussimoff came out to congratulate him, shaking Hogan's hand with a strong grip, which surprised the Hulkster. On the following week's Piper's Pit, Roussimoff was presented a slightly smaller trophy for being "the only undefeated wrestler in wrestling history." Although he had suffered a handful of countout and disqualification losses in WWF, he had never been pinned or forced to submit in a WWF ring. Hogan came out to congratulate him and ended up being the focal point of the interview. Apparently annoyed, Roussimoff walked out in the midst of Hogan's speech. A discussion between Roussimoff and Hogan was scheduled, and on a Piper's Pit that aired 7 February 1987, the two met. Hogan was introduced first, followed by Roussimoff, who was led by longtime rival Bobby Heenan. Speaking on behalf of his new protégé, Heenan accused Hogan of being Roussimoff's friend only so he would not have to defend his title against him. Hogan tried to reason with Roussimoff, but his pleas were ignored as he challenged Hogan to a match for the WWF World Heavyweight Championship at WrestleMania III. Hogan was still seemingly in disbelief as to what Roussimoff was doing, prompting Heenan to say "You can't believe it? Maybe you'll believe this, Hogan" before Roussimoff ripped off the T-shirt and crucifix from Hogan, with the crucifix scratching Hogan's chest, causing him to bleed. Following Hogan's acceptance of his challenge on a later edition of Piper's Pit, the two were part of a 20-man over-the-top-rope battle-royal on 14 March edition of Saturday Night's Main Event X at the Joe Louis Arena in Detroit. Although the battle royal was won by Hercules, Roussimoff claimed to have gained a psychological advantage over Hogan when he threw the WWF World Heavyweight Champion over the top rope. The match, which was actually taped on 21 February 1987, aired only two weeks before WrestleMania III to make it seem like Hogan had met his match in André the Giant. At WrestleMania III, he was billed at , and the stress of such immense weight on his bones and joints resulted in constant pain. After recent back surgery, he was also wearing a brace underneath his wrestling singlet. In front of a record crowd, Hogan won the match after body-slamming Roussimoff (later dubbed "the bodyslam heard around the world"), followed by Hogan's running leg drop finisher. Years later, Hogan claimed that Roussimoff was so heavy, he felt more like , and that he tore his latissimus dorsi muscle when slamming him. Another myth about the match is that no one, not even WWF owner Vince McMahon, knew until the day of the event whether Roussimoff would lose the match. In reality, he agreed to lose the match sometime before, mostly for health reasons. Contrary to popular belief, it was not the first time that Hogan had successfully body-slammed him in a WWF match. A then-heel Hogan had slammed a then-face Roussimoff following their match at the Showdown at Shea on 9 August 1980, though Roussimoff was somewhat lighter (around ) and more athletic at the time (Hogan also slammed him in a match in Hamburg, Pennsylvania, a month later). This took place in the territorial days of American wrestling three years before WWF began national expansion, so many of those who watched WrestleMania III had never seen the Giant slammed (Roussimoff had also previously allowed Harley Race, El Canek and Stan Hansen, among others, to slam him). By the time of WrestleMania III, the WWF went national, giving more meaning to the Roussimoff–Hogan match that took place then. The feud between Roussimoff and Hogan simmered during the summer of 1987, as Roussimoff's health declined. The feud began heating up again when wrestlers were named the captains of rival teams at the inaugural Survivor Series event. During their approximately one minute of battling each other during the match, Hogan dominated Roussimoff and was on the brink of knocking him from the ring, but was tripped up by his partners, Bundy and One Man Gang, and would be counted out. Roussimoff went on to be the sole survivor of the match, pinning Bam Bam Bigelow before Hogan returned to the ring to attack André and knock him out of the ring. Roussimoff later got revenge when, after Hogan won a match against Bundy on Saturday Night's Main Event, he snuck up from behind and began choking Hogan to the brink of unconsciousness, not letting go even after an army of seven face-aligned wrestlers ran to the ring to try to pull him away; it took Hacksaw Jim Duggan breaking a piece of wood over his back (which he no-sold) for him to let go, after which Hogan was pulled to safety. As was the case with the SNME battle royal a year earlier, the series of events was one of the pieces that helped build interest in a possible one-on-one rematch between Hogan and Roussimoff, and to make it seem that Roussimoff was certain to win easily when they did meet. Meanwhile, Rousimoff returned to Germany in December 1987 for another match with Wanz, which he lost by countout. In the meantime, the "Million Dollar Man" Ted DiBiase failed to persuade Hogan to sell him the WWF World Heavyweight Championship. After failing to defeat Hogan in a subsequent series of matches, DiBiase turned to Roussimoff to win it for him. He and DiBiase had teamed several times in the past, including in Japan and in the WWF in the late 1970s and early 1980s when both were faces, but this was not acknowledged during this new storyline. The earlier attack and DiBiase's insertion into the feud set up the Hogan-Roussimoff rematch on The Main Event, to air 5 February 1988, on a live broadcast on NBC. Acting as his hired gun, Roussimoff won the WWF World Heavyweight Championship from Hogan (his first singles title) in a match where it was later revealed that appointed referee Dave Hebner was "detained backstage", and a replacement (whom Hogan afterwards initially accused of having been paid by DiBiase to get plastic surgery to look like Dave, but was revealed to have been his evil twin brother, Earl Hebner), made a three count on Hogan while his shoulders were off the mat. After winning, Roussimoff "sold" the title to DiBiase; the transaction was declared invalid by then-WWF president Jack Tunney and the title was declared vacant. This was shown on WWF's NBC program The Main Event. At WrestleMania IV, Roussimoff and Hulk Hogan fought to a double disqualification in a WWF title tournament match (with the idea in the storyline saying that Roussimoff was again working on DiBiase's behalf in giving DiBiase a clearer path in the tournament). Afterward, Roussimoff and Hogan's feud died down after a steel cage match held at WrestleFest on 31 July 1988, in Milwaukee. Hogan was the winner. At the inaugural SummerSlam pay-per-view held at Madison Square Garden, Roussimoff and DiBiase (billed as The Mega Bucks) faced Hogan and WWF World Heavyweight Champion "Macho Man" Randy Savage (known as The Mega Powers) in the main event, with Jesse "The Body" Ventura as the special guest referee. During the match, the Mega Powers' manager, Miss Elizabeth, distracted the Mega Bucks and Ventura when she climbed up on the ring apron, removed her yellow skirt and walked around in a pair of red panties. This allowed Hogan and Savage time to recover and eventually win the match with Hogan pinning DiBiase. Savage forced Ventura's hand down for the final three-count, due to Ventura's character historically being at odds with Hogan, and his unwillingness to count the fall. Concurrent with the developing feud with the Mega Powers, Roussimoff was placed in a feud with Jim Duggan, which began after Duggan knocked out Roussimoff with a two-by-four board during a television taping. Despite Duggan's popularity with fans, Roussimoff regularly got the upper hand in the feud. Roussimoff's next major feud was against Jake "The Snake" Roberts. In this storyline, it was said Roussimoff was afraid of snakes, something Roberts exposed on Saturday Night's Main Event when he threw his snake, Damien, on the frightened Roussimoff; as a result, he suffered a kayfabe mild heart attack and vowed revenge. During the next few weeks, Roberts frequently walked to ringside carrying his snake in its bag during Roussimoff's matches, causing the latter to run from the ring in fright. Throughout their feud (which culminated at WrestleMania V), Roberts constantly used Damien to gain a psychological edge over the much larger and stronger Roussimoff. In 1989, Roussimoff and the returning Big John Studd briefly reprised their feud, beginning at WrestleMania V, when Studd was the referee in the match with Roberts, this time with Studd as a face and Roussimoff as the heel. During the late summer and autumn of 1989, Roussimoff engaged in a brief feud, consisting almost entirely of house shows (non-televised events), and one televised match on October 28, 1989, at Madison Square Garden with then-WWF Intercontinental Champion The Ultimate Warrior. Roussimoff began to wear face paint with a similar design to The Warrior and began called himself "The Ultimate Giant" when he appeared on The Brother Love Show. The younger Warrior, the WWF's rising star, regularly squashed the aging Roussimoff in an attempt to showcase his star quality and promote him as the "next big thing". Colossal Connection (1989–1990) In late 1989, Roussimoff was joined with fellow Heenan Family member Haku to form a new tag team called the Colossal Connection, in part to fill a void left by the departure of Tully Blanchard and Arn Anderson (the Brain Busters, who were also members of Heenan's stable) from the WWF, and also to continue to keep the aging Roussimoff in the main event spotlight. His last singles match was a loss to The Ultimate Warrior in 20 seconds at a house show in Cape Girardeau, Missouri on 11 December 1989. The Colossal Connection immediately targeted WWF Tag Team Champions Demolition (who had recently won the belts from the Brain Busters). At a television taping on 13 December 1989, the Colossal Connection defeated Demolition to win the titles. Roussimoff and Haku successfully defended their title, mostly against Demolition, until WrestleMania VI on 1 April 1990, when Demolition took advantage of a mistimed move by the champions to regain the belts. After the match, a furious Heenan blamed Roussimoff for the title loss and after shouting at him, slapped him in the face; an angry Roussimoff responded with a slap of his own that sent Heenan staggering from the ring. Roussimoff also caught Haku's kick attempt, sending him reeling from the ring as well, prompting support for Roussimoff and turning him face for the first time since 1987. Due to his ongoing health issues, Roussimoff was not able to wrestle at the time of Wrestlemania VI and Haku actually wrestled the entire match against Demolition without tagging him in. On weekend television shows following WrestleMania VI, Bobby Heenan vowed to spit in Roussimoff's face when he came crawling back to the Heenan Family. He wrestled one more time with Haku, teaming up to face Demolition on a house show in Honolulu on 10 April, Roussimoff was knocked out of the ring and The Colossal Connection lost via count-out. After the match, Roussimoff and Haku would fight each other, marking the end of the team. His final WWF match of 1990 came at a combined WWF/All Japan/New Japan show on 13 April in Tokyo, Japan when he teamed with Giant Baba to defeat Demolition in a non-title match. Roussimoff would win by gaining the pinfall on Smash. Sporadic appearances (1990–1991) Roussimoff returned in the winter of 1990, but it was not to the World Wrestling Federation. Instead, Roussimoff made an interview appearance for Herb Abrams' fledgling Universal Wrestling Federation on 11 October in Reseda, California. (the segment aired in 1991). He appeared in an interview segment with Captain Lou Albano and put over the UWF. The following month on 30 November at a house show in Miami, Florida, the World Wrestling Federation announced his return as a participant in the 1991 Royal Rumble (to be held in Miami two months later). Roussimoff was also mentioned as a participant on television but would ultimately back out due to a leg injury. His on-air return finally took place at the WWF's Super-Stars & Stripes Forever USA Network special on 17 March 1991, when he came out to shake the hand of Big Boss Man after an altercation with Mr. Perfect. The following week at WrestleMania VII, he came to the aid of the Boss Man in his match against Mr. Perfect. Roussimoff finally returned to action on 26 April 1991, in a six-man tag-team matchup when he teamed with The Rockers in a winning effort against Mr. Fuji and The Orient Express at a house show in Belfast, Northern Ireland. On 11 May 1991 he participated in a 17-man battle-royal at a house show in Detroit, which was won by Kerry Von Erich. This was Andre's final WWF match, although he was involved in several subsequent storylines. His last major WWF storyline following WrestleMania VII had the major heel managers (Bobby Heenan, Sensational Sherri, Slick, and Mr. Fuji) trying to recruit Roussimoff one-by-one, only to be turned down in various humiliating ways (e.g. Heenan had his hand crushed, Sherri received a spanking, Slick got locked in the trunk of the car he was offering to Roussimoff, and Mr. Fuji got a pie in his face). Finally, Jimmy Hart appeared live on WWF Superstars to announce that he had successfully signed Roussimoff to tag-team with Earthquake. When asked to confirm this by Gene Okerlund, Roussimoff denied the claims. This led to Earthquake's attacking Roussimoff from behind (injuring his knee). Jimmy Hart would later get revenge for the humiliation by secretly signing Tugboat and forming the Natural Disasters. This led to Roussimoff's final major WWF appearance at SummerSlam 1991, where he seconded the Bushwhackers in their match against the Disasters. Roussimoff was on crutches at ringside, and after the Disasters won the match, they set out to attack him, but the Legion of Doom made their way to ringside and got in between them and the Giant, who was preparing to defend himself with one of his crutches. The Disasters left the ringside area as they were outnumbered by the Legion of Doom, the Bushwhackers and Roussimoff, who struck both Earthquake and Typhoon (the former Tugboat) with the crutch as they left. His final WWF appearance came at a house show in Paris, France, on 9 October 1991. He was in Davey Boy Smith's corner as the Bulldog faced Earthquake; Smith hit Earthquake with Roussimoff's crutch, allowing Smith to win. All Japan Pro Wrestling; Universal Wrestling Association (1990–1992) After WrestleMania VI, Roussimoff spent the rest of his in-ring career in All Japan Pro Wrestling (AJPW) and Mexico's Universal Wrestling Association (UWA), where he performed under the name "André el Gigante". He toured with AJPW three times per year, from 1990 to 1992, usually teaming with Giant Baba in tag-team matches. Roussimoff made a couple of guest appearances for Herb Abrams' Universal Wrestling Federation, in 1991, feuding with Big John Studd, though he never had a match in the promotion. In his last U.S. television appearance, Andre appeared on World Championship Wrestling's (WCW) Clash of the Champions XX special that aired on TBS on 2 September 1992, where he gave a brief interview. During the same event, he appeared alongside Gordon Solie and was later seen talking with him during the gala celebrating the 20th anniversary of wrestling on TBS. He did his final tour of Mexico in 1992 in a selection of six-man tag matches alongside Bam Bam Bigelow and a variety of Lucha Libre stars facing among others Bad News Allen and future WWF Champions Mick Foley and Yokozuna. Roussimoff made his final tour with AJPW from October to December 1992; he wrestled what became the final match of his career on 4 December 1992, teaming with Giant Baba and Rusher Kimura to defeat Haruka Eigen, Masanobu Fuchi, and Motoshi Okuma. Acting career Roussimoff branched out into acting again in the 1970s and 1980s, after a 1967 French boxing film, making his USA acting debut playing a Sasquatch ("Bigfoot") in a two-part episode aired in 1976 on the television series The Six Million Dollar Man. He appeared in other television shows, including The Greatest American Hero, B. J. and the Bear, The Fall Guy and 1990's Zorro. Towards the end of his career, Roussimoff appeared in several films. He had an uncredited appearance in the 1984 film Conan the Destroyer as Dagoth, the resurrected horned giant god who is killed by Conan (Arnold Schwarzenegger). That same year, he also made an appearance in Micki & Maude (billed as André Rousimmoff). He appeared most notably as Fezzik, his own favorite role, in the 1987 film The Princess Bride. The fact that Roussimoff found that no one stared at him on set during production was a novel and particularly gratifying experience. Both the film and his performance retain a devoted following. In a short interview with Lanny Poffo, he stated that the movie meant so much to André that he made his wrestling pals watch an advanced copy of the VHS with him over and over again while supplying dinner, drinks, and sweetly asking each time, "Did you like my performance?". In his last film, he had a cameo role as a circus giant in the comedy Trading Mom, which was released in 1994, a year after his death. Filmography Personal life Roussimoff was mentioned in the 1974 Guinness Book of World Records as the then-highest-paid wrestler in history. He earned an annual salary of approximately $400,000 () at this time. Robin Christensen is Roussimoff's only child. Her mother Jean Christensen (who died in 2008) became acquainted with her father through the wrestling business around 1972 or 1973. Christensen had regular contact with her father, but saw him only five times in her life. After his death, Christensen spoke positively about her father and became a guardian of his image and legacy. In 1989, Roussimoff was arrested and charged with assault after he attacked a KCRG-TV cameraman shooting his match with The Ultimate Warrior at Cedar Rapids, Iowa's Five Seasons Center. While acquitted on the assault charge, he was fined $100 () for criminal mischief and ordered to pay KCRG $233 () in damage to its equipment. William Goldman, the author of the novel and the screenplay of The Princess Bride, wrote in his nonfiction work Which Lie Did I Tell? that Roussimoff was one of the gentlest and most generous people he ever knew. Whenever Roussimoff ate with someone in a restaurant, he would pay, but he would also insist on paying when he was a guest. On one occasion, after Roussimoff attended a dinner with Arnold Schwarzenegger and Wilt Chamberlain, Schwarzenegger had quietly moved to the cashier to pay before Roussimoff could, but then found himself being physically lifted, carried from his table and deposited on top of his car by Roussimoff and Chamberlain. Roussimoff owned a ranch in Ellerbe, North Carolina, looked after by two of his close friends. When he was not on the road, he loved spending time at the ranch, where he tended to his cattle, played with his dogs, and entertained friends. While there were custom-made chairs and a few other modifications in his home to accommodate his size, tales that everything in his home was custom-made for a large man are said to be exaggerated. Since Roussimoff could not easily go shopping due to his fame and size, he was known to spend hours watching and purchasing items from the shopping channel QVC. Health Roussimoff has been unofficially crowned "the greatest drunk on Earth" for once consuming 119 beers (in total, over or 11.16 gallons) in six hours. On Letterman, January 23, 1984, Roussimoff told David Letterman he drank 117 beers. When Letterman asked if he was drunk, Roussimoff said he couldn't remember because he passed out. He also said he quit drinking beer 14 months prior to this appearance on Letterman. On an episode of WWE's Legends of Wrestling, Mike Graham said Roussimoff once drank 156 beers (over ) in one sitting, which was confirmed by Dusty Rhodes. The Fabulous Moolah wrote in her autobiography that Roussimoff drank 127 beers at the bar of the Abraham Lincoln Hotel in Reading, Pennsylvania and later passed out in the lobby. The staff could not move him and had to leave him there until he awoke. In a shoot interview, Ken Patera recalled an occasion where Roussimoff was challenged by Dick Murdoch to a beer drinking contest. After nine or so hours, Roussimoff had drunk 116 beers. A tale recounted by Cary Elwes in his book about the making of The Princess Bride has Roussimoff falling on top of somebody while drunk, after which the NYPD sent an undercover officer to follow Roussimoff around whenever he went out drinking in their city to make sure he did not fall on anyone again. Another story also says prior to his famous WrestleMania III match, Roussimoff drank 14 bottles of wine. An urban legend exists surrounding Roussimoff's 1987 surgery in which his size made it impossible for the anesthesiologist to estimate a dosage via standard methods; consequently, his alcohol tolerance was used as a guideline instead. Roussimoff had severe pericardial effusion and had a pericardiocentesis at Duke University Hospital in the 1980s. Death Roussimoff died at age 46 of congestive heart failure and apparent heart attack in his sleep, likely associated with his untreated acromegaly, at a Paris hotel on the morning of Thursday 28 January 1993. He went to play cards with some friends on the night of Wednesday 27 January. He came back to his hotel room around 1 a.m. CET on 28 January. In the afternoon, Roussimoff was found dead in his room by hotel management and his chauffeur. He was in Paris to attend his father's funeral. While there, he decided to stay longer to be with his mother on her birthday. He spent the day before his death visiting and playing cards with some of his oldest friends in Molien. In his will, he specified that his remains should be cremated and "disposed of". Upon his death in Paris, his family in France held a funeral for him, intending to bury him near his father. When they learned of his wish to be cremated, his body was flown to the United States, where he was cremated according to his wishes. His ashes were scattered at his ranch () in Ellerbe, North Carolina. In addition, in accordance with his will, he left his estate to his sole beneficiary: his daughter Robin. Other media Roussimoff made numerous appearances as himself in video games, starting with WWF WrestleMania. He also appears posthumously in Virtual Pro Wrestling 64, WWF No Mercy, Legends of Wrestling, Legends of Wrestling II, Showdown: Legends of Wrestling, WWE SmackDown! vs. Raw, WWE SmackDown! vs. Raw 2006, WWE Legends of WrestleMania, WWE All Stars, WWE 2K14, WWE 2K15, WWE 2K16, WWE 2K17, WWE 2K18, WWE 2K19, WWE 2K20, WWE 2K Battlegrounds, WWE 2K22, WWE 2K23 and many others. In January 2005, WWE released André The Giant, a DVD focusing on the life and career of Roussimoff. The DVD is a reissue of the out-of-print André The Giant VHS made by Coliseum Video in 1985, with commentary by Michael Cole and Tazz replacing Gorilla Monsoon and Jesse Ventura's commentary on his WrestleMania match with Big John Studd. The video is hosted by Lord Alfred Hayes. Later matches, including his battles against Hulk Hogan while a heel, are not included on this VHS. Legacy In 1993, when the then-World Wrestling Federation created the WWF Hall of Fame, André the Giant was the inaugural and sole inductee in the class of 1993. Roussimoff was the inspiration for the 1998 film My Giant, written by his friend Billy Crystal, whom he had met during the filming of The Princess Bride. Paul Wight, better known as Big Show, is more similar in body structure to Roussimoff than any other wrestler since Roussimoff's death. He was originally billed as the son of André during his stint in WCW (when he was known as simply "the Giant") despite there being no biological relationship. While also suffering from acromegaly, unlike Roussimoff, Wight did get surgery on his pituitary gland in the early 1990s, which successfully halted the progress of his condition. The former wrestler Giant González suffered from problems similar to those that Roussimoff had near the end of his life and died in 2010 due to diabetes complications. In 1999, he was the subject of an episode of A&E Biography, titled André the Giant: Larger Than Life. The documentary covered his childhood and early life in France, as well as the beginning of his wrestling career, his struggles with acromegaly, his personal life, and his final years. His brother, Jacques Roussimoff, was interviewed for the documentary, as were fellow wrestling personalities Gorilla Monsoon, Tim White, Arnold Skaaland, Vince McMahon, Freddie Blassie, Killer Kowalski, Rene Goulet, and Frenchy Bernard, as well as wrestling historian Sheldon Goldberg. Several of his longtime hometown friends were interviewed as well. The documentary described Roussimoff as pro wrestling's "first and only international attraction" and that "on his broad shoulders, wrestling rose from its status as a questionable sport to become big business, and some might argue, performance art." The Obey brand icon originated from wheatpaste posters that artist Shepard Fairey created based upon a photo of André the Giant that he had found in a newspaper. Capcom's video game character Hugo, from the Street Fighter series (known as Andore in the Final Fight series) is based on him. The 2014 graphic novel André The Giant: The Life and The Legend (First Second Books), written and drawn by Box Brown, tells the story of his life and career. Research for the book included interviews with his fellow wrestlers and actors such as Christopher Guest, Mandy Patinkin and others. In 2017, Showtime released Waiting for Andre, a semi-fictional movie about the friendship between playwright Samuel Beckett and Roussimoff during the time Beckett lived in Ussy-sur-Marne, outside of Paris. A novel of the movie was published the following year by Steffan Piper ( / 198075621X from Amazon print on demand). On 10 March 2014, episode of Raw, WrestleMania XXX host Hulk Hogan announced that in honor of Roussimoff's legacy, WWE was establishing the André the Giant Memorial Battle Royal, that would take place at the event, with the winner receiving the André the Giant Memorial Trophy (made in the likeness of Roussimoff). On 6 April 2014, at WrestleMania XXX, Cesaro won the match after eliminating Big Show using a body slam similar to the body slam Hulk Hogan used on Roussimoff at WrestleMania III. The battle royal has since become a yearly WrestleMania Weekend tradition. Biopics In 1999, Biography produced and aired a documentary called Andre The Giant: Larger Than Life. On 9 May 2016, it was announced that a movie based on the 2015 authorized graphic novel biography André the Giant: Closer to Heaven was in the plans made by Lion Forge Comics along with producers Scott Steindorff, Dylan Russell and consulted by Roussimoff's daughter, Robin Christensen-Roussimoff. On 10 April 2018, HBO aired a documentary film called André the Giant.

The Apache HTTP Server ( ) is a free and open-source cross-platform web server software, released under the terms of Apache License 2.0. It is developed and maintained by a community of developers under the auspices of the Apache Software Foundation. The vast majority of Apache HTTP Server instances run on a Linux distribution, but current versions also run on Microsoft Windows, OpenVMS, and a wide variety of Unix-like systems. Past versions also ran on NetWare, OS/2 and other operating systems, including ports to mainframes. Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled. Apache played a key role in the initial growth of the World Wide Web, quickly overtaking NCSA HTTPd as the dominant HTTP server. In 2009, it became the first web server software to serve more than 100 million websites. , Netcraft estimated that Apache served 23.04% of the million busiest websites, while Nginx served 22.01%; Cloudflare at 19.53% and Microsoft Internet Information Services at 5.78% rounded out the top four. For some of Netcraft's other stats, Nginx is ahead of Apache. According to W3Techs' review of all web sites, in June 2022 Apache was ranked second at 31.4% and Nginx first at 33.6%, with Cloudflare Server third at 21.6%. Name According to The Apache Software Foundation, its name was chosen "from respect for the various Native American nations collectively referred to as Apache, well-known for their superior skills in warfare strategy and their inexhaustible endurance". This was in a context in which it seemed that the open internet -- based on free exchange of open source code -- appeared to be soon subjected to a kind of conquer by proprietary software vendor Microsoft; Apache co-creator Brian Behlendorf -- originator of the name -- saw his effort somewhat parallel that of Geronimo, Chief of the last of the free Apache peoples. But it conceded that the name "also makes a cute pun on 'a patchy web server'—a server made from a series of patches". There are other sources for the "patchy" software pun theory, including the project's official documentation in 1995, which stated: "Apache is a cute name which stuck. It was based on some existing code and a series of software patches, a pun on 'A PAtCHy' server." But in an April 2000 interview, Behlendorf asserted that the origins of Apache were not a pun, stating: In January 2023, the US-based non-profit Natives in Tech accused the Apache Software Foundation of cultural appropriation and urged them to change the foundation's name, and consequently also the names of the software projects it hosts. When Apache is running under Unix, its process name is , which is short for "HTTP daemon". Feature overview Apache supports a variety of features, many implemented as compiled modules which extend the core functionality. These can range from authentication schemes to supporting server-side programming languages such as Perl, Python, Tcl and PHP. Popular authentication modules include mod_access, mod_auth, mod_digest, and mod_auth_digest, the successor to mod_digest. A sample of other features include Secure Sockets Layer and Transport Layer Security support (mod_ssl), a proxy module (mod_proxy), a URL rewriting module (mod_rewrite), custom log files (mod_log_config), and filtering support (mod_include and mod_ext_filter). Popular compression methods on Apache include the external extension module, mod_gzip, implemented to help with reduction of the size (weight) of web pages served over HTTP. ModSecurity is an open source intrusion detection and prevention engine for Web applications. Apache logs can be analyzed through a Web browser using free scripts, such as AWStats/W3Perl or Visitors. Virtual hosting allows one Apache installation to serve many different websites. For example, one computer with one Apache installation could simultaneously serve example.com, example.org, test47.test-server.example.edu, etc. Apache features configurable error messages, DBMS-based authentication databases, content negotiation and supports several graphical user interfaces (GUIs). It supports password authentication and digital certificate authentication. Because the source code is freely available, anyone can adapt the server for specific needs, and there is a large public library of Apache add-ons. A more detailed list of features is provided below: Loadable Dynamic Modules Multiple Request Processing modes (MPMs) including Event-based/Async, Threaded and Prefork. Highly scalable (easily handles more than 10,000 simultaneous connections) Handling of static files, index files, auto-indexing and content negotiation .htaccess per-directory configuration support Reverse proxy with caching Load balancing with in-band health checks Multiple load balancing mechanisms Fault tolerance and Failover with automatic recovery WebSocket, FastCGI, SCGI, AJP and uWSGI support with caching Dynamic configuration TLS/SSL with SNI and OCSP stapling support, via OpenSSL or wolfSSL. Name- and IP address-based virtual servers IPv6-compatible HTTP/2 support Fine-grained authentication and authorization access control gzip compression and decompression URL rewriting Headers and content rewriting Custom logging with rotation Concurrent connection limiting Request processing rate limiting Bandwidth throttling Server Side Includes IP address-based geolocation User and Session tracking WebDAV Embedded Perl, PHP and Lua scripting CGI support public_html per-user web-pages Generic expression parser Real-time status views FTP support (by a separate module) Performance Instead of implementing a single architecture, Apache provides a variety of MultiProcessing Modules (MPMs), which allow it to run in either a process-based mode, a hybrid (process and thread) mode, or an event-hybrid mode, in order to better match the demands of each particular infrastructure. Choice of MPM and configuration is therefore important. Where compromises in performance must be made, Apache is designed to reduce latency and increase throughput relative to simply handling more requests, thus ensuring consistent and reliable processing of requests within reasonable time-frames. For delivering static pages, Apache 2.2 series was considered significantly slower than nginx and varnish. To address this issue, the Apache developers created the Event MPM, which mixes the use of several processes and several threads per process in an asynchronous event-based loop. This architecture as implemented in the Apache 2.4 series performs at least as well as event-based web servers, according to Jim Jagielski and other independent sources. However, some independent but significantly outdated benchmarks show that it is still half as fast as nginx, e.g. Licensing The Apache HTTP Server codebase was relicensed to the Apache 2.0 License (from the previous 1.1 license) in January 2004, and Apache HTTP Server 1.3.31 and 2.0.49 were the first releases using the new license. The OpenBSD project did not like the change and continued the use of pre-2.0 Apache versions, effectively forking Apache 1.3.x for its purposes. They initially replaced it with Nginx, and soon after made their own replacement, OpenBSD Httpd, based on the Relayd project. Versions Version 1.1: The Apache License 1.1 was approved by the ASF in 2000: The primary change from the 1.0 license is in the 'advertising clause' (section 3 of the 1.0 license); derived products are no longer required to include attribution in their advertising materials, only in their documentation. Version 2.0: The ASF adopted the Apache License 2.0 in January 2004. The stated goals of the license included making the license easier for non-ASF projects to use, improving compatibility with GPL-based software, allowing the license to be included by reference instead of listed in every file, clarifying the license on contributions, and requiring a patent license on contributions that necessarily infringe a contributor's own patents. Development The Apache HTTP Server Project is a collaborative software development effort aimed at creating a robust, commercial-grade, feature-rich and freely available source code implementation of an HTTP (Web) server. The project is jointly managed by a group of volunteers located around the world, using the Internet and the Web to communicate, plan, and develop the server and its related documentation. This project is part of the Apache Software Foundation. In addition, hundreds of users have contributed ideas, code, and documentation to the project. Apache 2.4 dropped support for BeOS, TPF, A/UX, NeXT, and Tandem platforms. Security Apache, like other server software, can be hacked and exploited. The main Apache attack tool is Slowloris, which exploits a bug in Apache software. It creates many sockets and keeps each of them alive and busy by sending several bytes (known as "keep-alive headers") to let the server know that the computer is still connected and not experiencing network problems. The Apache developers have addressed Slowloris with several modules to limit the damage caused; the Apache modules mod_limitipconn, mod_qos, mod_evasive, mod security, mod_noloris, and mod_antiloris have all been suggested as means of reducing the likelihood of a successful Slowloris attack. Since Apache 2.2.15, Apache ships the module mod_reqtimeout as the official solution supported by the developers.

Accounting, also known as accountancy, is the processing of information about economic entities, such as businesses and corporations. Accounting measures the results of an organization's economic activities and conveys this information to a variety of stakeholders, including investors, creditors, management, and regulators. Practitioners of accounting are known as accountants. The terms "accounting" and "financial reporting" are often used as synonyms. Accounting can be divided into several fields including financial accounting, management accounting, tax accounting and cost accounting. Financial accounting focuses on the reporting of an organization's financial information, including the preparation of financial statements, to the external users of the information, such as investors, regulators and suppliers. Management accounting focuses on the measurement, analysis and reporting of information for internal use by management. The recording of financial transactions, so that summaries of the financials may be presented in financial reports, is known as bookkeeping, of which double-entry bookkeeping is the most common system. Accounting information systems are designed to support accounting functions and related activities. Accounting has existed in various forms and levels of sophistication throughout human history. The double-entry accounting system in use today was developed in medieval Europe, particularly in Venice, and is usually attributed to the Italian mathematician and Franciscan friar Luca Pacioli. Today, accounting is facilitated by accounting organizations such as standard-setters, accounting firms and professional bodies. Financial statements are usually audited by accounting firms, and are prepared in accordance with generally accepted accounting principles (GAAP). GAAP is set by various standard-setting organizations such as the Financial Accounting Standards Board (FASB) in the United States and the Financial Reporting Council in the United Kingdom. As of 2012, "all major economies" have plans to converge towards or adopt the International Financial Reporting Standards (IFRS). History Accounting is thousands of years old and can be traced to ancient civilizations. One early development of accounting dates back to ancient Mesopotamia, and is closely related to developments in writing, counting and money; there is also evidence of early forms of bookkeeping in ancient Iran, and early auditing systems by the ancient Egyptians and Babylonians. By the time of Emperor Augustus, the Roman government had access to detailed financial information. Double-entry bookkeeping was pioneered in the Jewish community of the early-medieval Middle East and was further refined in medieval Europe. With the development of joint-stock companies, accounting split into financial accounting and management accounting. The first published work on a double-entry bookkeeping system was the Summa de arithmetica, published in Italy in 1494 by Luca Pacioli (the "Father of Accounting"). Accounting began to transition into an organized profession in the nineteenth century, with local professional bodies in England merging to form the Institute of Chartered Accountants in England and Wales in 1880. Etymology Both the words accounting and accountancy were in use in Great Britain by the mid-1800s, and are derived from the words accompting and accountantship used in the 18th century. In Middle English (used roughly between the 12th and the late 15th century) the verb "to account" had the form accounten, which was derived from the Old French word aconter, which is in turn related to the Vulgar Latin word computare, meaning "to reckon". The base of computare is putare, which "variously meant to prune, to purify, to correct an account, hence, to count or calculate, as well as to think". The word "accountant" is derived from the French word , which is also derived from the Italian and Latin word . The word was formerly written in English as "accomptant", but in process of time the word, which was always pronounced by dropping the "p", became gradually changed both in pronunciation and in orthography to its present form. Terminology Accounting has variously been defined as the keeping or preparation of the financial records of transactions of the firm, the analysis, verification and reporting of such records and "the principles and procedures of accounting"; it also refers to the job of being an accountant. Accountancy refers to the occupation or profession of an accountant, particularly in British English. Topics Accounting has several subfields or subject areas, including financial accounting, management accounting, auditing, taxation and accounting information systems. Financial accounting Financial accounting focuses on the reporting of an organization's financial information to external users of the information, such as investors, potential investors and creditors. It calculates and records business transactions and prepares financial statements for the external users in accordance with generally accepted accounting principles (GAAP). GAAP, in turn, arises from the wide agreement between accounting theory and practice, and change over time to meet the needs of decision-makers. Financial accounting produces past-oriented reports—for example financial statements are often published six to ten months after the end of the accounting period—on an annual or quarterly basis, generally about the organization as a whole. Management accounting Management accounting focuses on the measurement, analysis and reporting of information that can help managers in making decisions to fulfill the goals of an organization. In management accounting, internal measures and reports are based on cost-benefit analysis, and are not required to follow the generally accepted accounting principle (GAAP). In 2014 CIMA created the Global Management Accounting Principles (GMAPs). The result of research from across 20 countries in five continents, the principles aim to guide best practice in the discipline. Management accounting produces past-oriented reports with time spans that vary widely, but it also encompasses future-oriented reports such as budgets. Management accounting reports often include financial and non financial information, and may, for example, focus on specific products and departments. Auditing Auditing is the verification of assertions made by others regarding a payoff, and in the context of accounting it is the "unbiased examination and evaluation of the financial statements of an organization". Audit is a professional service that is systematic and conventional. An audit of financial statements aims to express or disclaim an independent opinion on the financial statements. The auditor expresses an independent opinion on the fairness with which the financial statements presents the financial position, results of operations, and cash flows of an entity, in accordance with the generally accepted accounting principles (GAAP) and "in all material respects". An auditor is also required to identify circumstances in which the generally accepted accounting principles (GAAP) have not been consistently observed. Information systems An accounting information system is a part of an organization's information system used for processing accounting data. Many corporations use artificial intelligence-based information systems. The banking and finance industry uses AI in fraud detection. The retail industry uses AI for customer services. AI is also used in the cybersecurity industry. It involves computer hardware and software systems using statistics and modeling. Many accounting practices have been simplified with the help of accounting computer-based software. An enterprise resource planning (ERP) system is commonly used for a large organisation and it provides a comprehensive, centralized, integrated source of information that companies can use to manage all major business processes, from purchasing to manufacturing to human resources. These systems can be cloud based and available on demand via application or browser, or available as software installed on specific computers or local servers, often referred to as on-premise. Tax accounting Tax accounting in the United States concentrates on the preparation, analysis and presentation of tax payments and tax returns. The U.S. tax system requires the use of specialised accounting principles for tax purposes which can differ from the generally accepted accounting principles (GAAP) for financial reporting. U.S. tax law covers four basic forms of business ownership: sole proprietorship, partnership, corporation, and limited liability company. Corporate and personal income are taxed at different rates, both varying according to income levels and including varying marginal rates (taxed on each additional dollar of income) and average rates (set as a percentage of overall income). Forensic accounting Forensic accounting is a specialty practice area of accounting that describes engagements that result from actual or anticipated disputes or litigation. "Forensic" means "suitable for use in a court of law", and it is to that standard and potential outcome that forensic accountants generally have to work. Political campaign accounting Political campaign accounting deals with the development and implementation of financial systems and the accounting of financial transactions in compliance with laws governing political campaign operations. This branch of accounting was first formally introduced in the March 1976 issue of The Journal of Accountancy. Organizations Professional bodies Professional accounting bodies include the American Institute of Certified Public Accountants (AICPA) and the other 179 members of the International Federation of Accountants (IFAC), including Institute of Chartered Accountants of Scotland (ICAS), Institute of Chartered Accountants of Pakistan (ICAP), CPA Australia, Institute of Chartered Accountants of India, Association of Chartered Certified Accountants (ACCA) and Institute of Chartered Accountants in England and Wales (ICAEW). Some countries have a single professional accounting body and, in some other countries, professional bodies for subfields of the accounting professions also exist, for example the Chartered Institute of Management Accountants (CIMA) in the UK and Institute of management accountants in the United States. Many of these professional bodies offer education and training including qualification and administration for various accounting designations, such as certified public accountant (AICPA) and chartered accountant. Firms Depending on its size, a company may be legally required to have their financial statements audited by a qualified auditor, and audits are usually carried out by accounting firms. Accounting firms grew in the United States and Europe in the late nineteenth and early twentieth century, and through several mergers there were large international accounting firms by the mid-twentieth century. Further large mergers in the late twentieth century led to the dominance of the auditing market by the "Big Five" accounting firms: Arthur Andersen, Deloitte, Ernst & Young, KPMG and PricewaterhouseCoopers. The demise of Arthur Andersen following the Enron scandal reduced the Big Five to the Big Four. Standard-setters Generally accepted accounting principles (GAAP) are accounting standards issued by national regulatory bodies. In addition, the International Accounting Standards Board (IASB) issues the International Financial Reporting Standards (IFRS) implemented by 147 countries. Standards for international audit and assurance, ethics, education, and public sector accounting are all set by independent standard settings boards supported by IFAC. The International Auditing and Assurance Standards Board sets international standards for auditing, assurance, and quality control; the International Ethics Standards Board for Accountants (IESBA) sets the internationally appropriate principles-based Code of Ethics for Professional Accountants; the International Accounting Education Standards Board (IAESB) sets professional accounting education standards; and International Public Sector Accounting Standards Board (IPSASB) sets accrual-based international public sector accounting standards. Organizations in individual countries may issue accounting standards unique to the countries. For example, in Australia, the Australian Accounting Standards Board manages the issuance of the accounting standards in line with IFRS. In the United States the Financial Accounting Standards Board (FASB) issues the Statements of Financial Accounting Standards, which form the basis of US GAAP, and in the United Kingdom the Financial Reporting Council (FRC) sets accounting standards. However, as of 2012 "all major economies" have plans to converge towards or adopt the IFRS. Education, training and qualifications Degrees At least a bachelor's degree in accounting or a related field is required for most accountant and auditor job positions, and some employers prefer applicants with a master's degree. A degree in accounting may also be required for, or may be used to fulfill the requirements for, membership to professional accounting bodies. For example, the education during an accounting degree can be used to fulfill the American Institute of CPA's (AICPA) 150 semester hour requirement, and associate membership with the Certified Public Accountants Association of the UK is available after gaining a degree in finance or accounting. A doctorate is required in order to pursue a career in accounting academia, for example, to work as a university professor in accounting. The Doctor of Philosophy (PhD) and the Doctor of Business Administration (DBA) are the most popular degrees. The PhD is the most common degree for those wishing to pursue a career in academia, while DBA programs generally focus on equipping business executives for business or public careers requiring research skills and qualifications. Professional qualifications Professional accounting qualifications include the chartered accountant designations and other qualifications including certificates and diplomas. In Scotland, chartered accountants of ICAS undergo Continuous Professional Development and abide by the ICAS code of ethics. In England and Wales, chartered accountants of the ICAEW undergo annual training, and are bound by the ICAEW's code of ethics and subject to its disciplinary procedures. In the United States, the requirements for joining the AICPA as a Certified Public Accountant are set by the Board of Accountancy of each state, and members agree to abide by the AICPA's Code of Professional Conduct and Bylaws. The ACCA is the largest global accountancy body with over 320,000 members, and the organisation provides an 'IFRS stream' and a 'UK stream'. Students must pass a total of 14 exams, which are arranged across three levels. Research Accounting research is research in the effects of economic events on the process of accounting, the effects of reported information on economic events, and the roles of accounting in organizations and society. It encompasses a broad range of research areas including financial accounting, management accounting, auditing and taxation. Accounting research is carried out both by academic researchers and practicing accountants. Methodologies in academic accounting research include archival research, which examines "objective data collected from repositories"; experimental research, which examines data "the researcher gathered by administering treatments to subjects"; analytical research, which is "based on the act of formally modeling theories or substantiating ideas in mathematical terms"; interpretive research, which emphasizes the role of language, interpretation and understanding in accounting practice, "highlighting the symbolic structures and taken-for-granted themes which pattern the world in distinct ways"; critical research, which emphasizes the role of power and conflict in accounting practice; case studies; computer simulation; and field research. Empirical studies document that leading accounting journals publish in total fewer research articles than comparable journals in economics and other business disciplines, and consequently, accounting scholars are relatively less successful in academic publishing than their business school peers. Due to different publication rates between accounting and other business disciplines, a recent study based on academic author rankings concludes that the competitive value of a single publication in a top-ranked journal is highest in accounting and lowest in marketing. Scandals The year 2001 witnessed a series of financial information frauds involving Enron, auditing firm Arthur Andersen, the telecommunications company WorldCom, Qwest and Sunbeam, among other well-known corporations. These problems highlighted the need to review the effectiveness of accounting standards, auditing regulations and corporate governance principles. In some cases, management manipulated the figures shown in financial reports to indicate a better economic performance. In others, tax and regulatory incentives encouraged over-leveraging of companies and decisions to bear extraordinary and unjustified risk. The Enron scandal deeply influenced the development of new regulations to improve the reliability of financial reporting, and increased public awareness about the importance of having accounting standards that show the financial reality of companies and the objectivity and independence of auditing firms. In addition to being the largest bankruptcy reorganization in American history, the Enron scandal undoubtedly is the biggest audit failure causing the dissolution of Arthur Andersen, which at the time was one of the five largest accounting firms in the world. After a series of revelations involving irregular accounting procedures conducted throughout the 1990s, Enron filed for Chapter 11 bankruptcy protection in December 2001. One consequence of these events was the passage of the Sarbanes–Oxley Act in the United States in 2002, as a result of the first admissions of fraudulent behavior made by Enron. The act significantly raises criminal penalties for securities fraud, for destroying, altering or fabricating records in federal investigations or any scheme or attempt to defraud shareholders. Fraud and error Accounting fraud is an intentional misstatement or omission in the accounting records by management or employees which involves the use of deception. It is a criminal act and a breach of civil tort. It may involve collusion with third parties. An accounting error is an unintentional misstatement or omission in the accounting records, for example misinterpretation of facts, mistakes in processing data, or oversights leading to incorrect estimates. Acts leading to accounting errors are not criminal but may breach civil law, for example, the tort of negligence. The primary responsibility for the prevention and detection of fraud and errors rests with the entity's management.

Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" (gynes). The colonies are described as superorganisms because the ants appear to operate as a unified entity, collectively working together to support the colony. Ants have colonised almost every landmass on Earth. The only places lacking indigenous ants are Antarctica and a few remote or inhospitable islands. Ants thrive in moist tropical ecosystems and may exceed the combined biomass of wild birds and mammals. Their success in so many environments has been attributed to their social organisation and their ability to modify habitats, tap resources, and defend themselves. Their long co-evolution with other species has led to mimetic, commensal, parasitic, and mutualistic relationships. Ant societies have division of labour, communication between individuals, and an ability to solve complex problems. These parallels with human societies have long been an inspiration and subject of study. Many human cultures make use of ants in cuisine, medication, and rites. Some species are valued in their role as biological pest control agents. Their ability to exploit resources may bring ants into conflict with humans, however, as they can damage crops and invade buildings. Some species, such as the red imported fire ant (Solenopsis invicta) of South America, are regarded as invasive species in other parts of the world, establishing themselves in areas where they have been introduced accidentally. Etymology The word ant and the archaic word emmet are derived from , of Middle English, which come from of Old English; these are all related to Low Saxon , and varieties (Old Saxon ) and to German (Old High German ). All of these words come from West Germanic *, and the original meaning of the word was "the biter" (from Proto-Germanic , "off, away" + "cut"). The family name Formicidae is derived from the Latin ("ant") from which the words in other Romance languages, such as the Portuguese , Italian , Spanish , Romanian , and French are derived. It has been hypothesised that a Proto-Indo-European word *morwi- was the root for Sanskrit vamrah, Greek μύρμηξ mýrmēx, Old Church Slavonic mraviji, Old Irish moirb, Old Norse maurr, Dutch mier, Swedish myra, Danish myre, Middle Dutch miere, and Crimean Gothic miera. Taxonomy and evolution The family Formicidae belongs to the order Hymenoptera, which also includes sawflies, bees, and wasps. Ants evolved from a lineage within the stinging wasps, and a 2013 study suggests that they are a sister group of the Apoidea. In 1966, E. O. Wilson and his colleagues identified the fossil remains of an ant (Sphecomyrma) that lived in the Cretaceous period. The specimen, trapped in amber dating back to around 92 million years ago, has features found in some wasps, but not found in modern ants. The oldest fossils of ants date to the mid-Cretaceous, around 100 million years ago, which belong to extinct stem-groups such as the Haidomyrmecinae, Sphecomyrminae and Zigrasimeciinae, with modern ant subfamilies appearing towards the end of the Cretaceous around 80–70 million years ago. Ants diversified and assumed ecological dominance around 60 million years ago. Some groups, such as the Leptanillinae and Martialinae, are suggested to have diversified from early primitive ants that were likely to have been predators underneath the surface of the soil. During the Cretaceous period, a few species of primitive ants ranged widely on the Laurasian supercontinent (the Northern Hemisphere). Their representation in the fossil record is poor, in comparison to the populations of other insects, representing only about 1% of fossil evidence of insects in the era. Ants became dominant after adaptive radiation at the beginning of the Paleogene period. By the Oligocene and Miocene, ants had come to represent 20–40% of all insects found in major fossil deposits. Of the species that lived in the Eocene epoch, around one in 10 genera survive to the present. Genera surviving today comprise 56% of the genera in Baltic amber fossils (early Oligocene), and 92% of the genera in Dominican amber fossils (apparently early Miocene). Termites live in colonies and are sometimes called "white ants", but termites are only distantly related to ants. They are the sub-order Isoptera, and together with cockroaches, they form the order Blattodea. Blattodeans are related to mantids, crickets, and other winged insects that do not undergo full metamorphosis. Like ants, termites are eusocial, with sterile workers, but they differ greatly in the genetics of reproduction. The similarity of their social structure to that of ants is attributed to convergent evolution. Velvet ants look like large ants, but are wingless female wasps. Distribution and diversity Ants have a cosmopolitan distribution. They are found on all continents except Antarctica, and only a few large islands, such as Greenland, Iceland, parts of Polynesia and the Hawaiian Islands lack native ant species. Ants occupy a wide range of ecological niches and exploit many different food resources as direct or indirect herbivores, predators and scavengers. Most ant species are omnivorous generalists, but a few are specialist feeders. There is considerable variation in ant abundance across habitats, peaking in the moist tropics to nearly six times that found in less suitable habitats. Their ecological dominance has been examined primarily using estimates of their biomass: myrmecologist E. O. Wilson had estimated in 2009 that at any one time the total number of ants was between one and ten quadrillion (short scale) (i.e., between 1015 and 1016) and using this estimate he had suggested that the total biomass of all the ants in the world was approximately equal to the total biomass of the entire human race. More careful estimates made in 2022 which take into account regional variations puts the global ant contribution at 12 megatons of dry carbon, which is about 20% of the total human contribution, but greater than that of the wild birds and mammals combined. This study also puts a conservative estimate of the ants at about 20 × 1015 (20 quadrillion). Ants range in size from , the largest species being the fossil Titanomyrma giganteum, the queen of which was long with a wingspan of . Ants vary in colour; most ants are yellow to red or brown to black, but a few species are green and some tropical species have a metallic lustre. More than 13,800 species are currently known (with upper estimates of the potential existence of about 22,000; see the article List of ant genera), with the greatest diversity in the tropics. Taxonomic studies continue to resolve the classification and systematics of ants. Online databases of ant species, including AntWeb and the Hymenoptera Name Server, help to keep track of the known and newly described species. The relative ease with which ants may be sampled and studied in ecosystems has made them useful as indicator species in biodiversity studies. Morphology Ants are distinct in their morphology from other insects in having geniculate (elbowed) antennae, metapleural glands, and a strong constriction of their second abdominal segment into a node-like petiole. The head, mesosoma, and metasoma are the three distinct body segments (formally tagmata). The petiole forms a narrow waist between their mesosoma (thorax plus the first abdominal segment, which is fused to it) and gaster (abdomen less the abdominal segments in the petiole). The petiole may be formed by one or two nodes (the second alone, or the second and third abdominal segments). Tergosternal fusion, when the tergite and sternite of a segment fuse together, can occur partly or fully on the second, third and fourth abdominal segment and is used in identification. Fourth abdominal tergosternal fusion was formerly used as character that defined the poneromorph subfamilies, Ponerinae and relatives within their clade, but this is no longer considered a synapomorphic character. Like other arthropods, ants have an exoskeleton, an external covering that provides a protective casing around the body and a point of attachment for muscles, in contrast to the internal skeletons of humans and other vertebrates. Insects do not have lungs; oxygen and other gases, such as carbon dioxide, pass through their exoskeleton via tiny valves called spiracles. Insects also lack closed blood vessels; instead, they have a long, thin, perforated tube along the top of the body (called the "dorsal aorta") that functions like a heart, and pumps haemolymph toward the head, thus driving the circulation of the internal fluids. The nervous system consists of a ventral nerve cord that runs the length of the body, with several ganglia and branches along the way reaching into the extremities of the appendages. Head An ant's head contains many sensory organs. Like most insects, ants have compound eyes made from numerous tiny lenses attached together. Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization. Compared to vertebrates, ants tend to have blurrier eyesight, particularly in smaller species, and a few subterranean taxa are completely blind. However, some ants, such as Australia's bulldog ant, have excellent vision and are capable of discriminating the distance and size of objects moving nearly a meter away. Two antennae ("feelers") are attached to the head; these organs detect chemicals, air currents, and vibrations; they also are used to transmit and receive signals through touch. The head has two strong jaws, the mandibles, used to carry food, manipulate objects, construct nests, and for defence. In some species, a small pocket (infrabuccal chamber) inside the mouth stores food, so it may be passed to other ants or their larvae. Mesosoma Both the legs and wings of the ant are attached to the mesosoma ("thorax"). The legs terminate in a hooked claw which allows them to hook on and climb surfaces. Only reproductive ants (queens and males) have wings. Queens shed their wings after the nuptial flight, leaving visible stubs, a distinguishing feature of queens. In a few species, wingless queens (ergatoids) and males occur. Metasoma The metasoma (the "abdomen") of the ant houses important internal organs, including those of the reproductive, respiratory (tracheae), and excretory systems. Workers of many species have their egg-laying structures modified into stings that are used for subduing prey and defending their nests. Polymorphism In the colonies of a few ant species, there are physical castes—workers in distinct size-classes, called minor, median, and major ergates. Often, the larger ants have disproportionately larger heads, and correspondingly stronger mandibles. These are known as macrergates while smaller workers are known as micrergates. Although formally known as dinergates, such individuals are sometimes called "soldier" ants because their stronger mandibles make them more effective in fighting, although they still are workers and their "duties" typically do not vary greatly from the minor or median workers. In a few species, the median workers are absent, creating a sharp divide between the minors and majors. Weaver ants, for example, have a distinct bimodal size distribution. Some other species show continuous variation in the size of workers. The smallest and largest workers in Carebara diversa show nearly a 500-fold difference in their dry weights. Workers cannot mate; however, because of the haplodiploid sex-determination system in ants, workers of a number of species can lay unfertilised eggs that become fully fertile, haploid males. The role of workers may change with their age and in some species, such as honeypot ants, young workers are fed until their gasters are distended, and act as living food storage vessels. These food storage workers are called repletes. For instance, these replete workers develop in the North American honeypot ant Myrmecocystus mexicanus. Usually the largest workers in the colony develop into repletes; and, if repletes are removed from the colony, other workers become repletes, demonstrating the flexibility of this particular polymorphism. This polymorphism in morphology and behaviour of workers initially was thought to be determined by environmental factors such as nutrition and hormones that led to different developmental paths; however, genetic differences between worker castes have been noted in Acromyrmex sp. These polymorphisms are caused by relatively small genetic changes; differences in a single gene of Solenopsis invicta can decide whether the colony will have single or multiple queens. The Australian jack jumper ant (Myrmecia pilosula) has only a single pair of chromosomes (with the males having just one chromosome as they are haploid), the lowest number known for any animal, making it an interesting subject for studies in the genetics and developmental biology of social insects. Genome size Genome size is a fundamental characteristic of an organism. Ants have been found to have tiny genomes, with the evolution of genome size suggested to occur through loss and accumulation of non-coding regions, mainly transposable elements, and occasionally by whole genome duplication. This may be related to colonisation processes, but further studies are needed to verify this. Life cycle The life of an ant starts from an egg; if the egg is fertilised, the progeny will be female diploid, if not, it will be male haploid. Ants develop by complete metamorphosis with the larva stages passing through a pupal stage before emerging as an adult. The larva is largely immobile and is fed and cared for by workers. Food is given to the larvae by trophallaxis, a process in which an ant regurgitates liquid food held in its crop. This is also how adults share food, stored in the "social stomach". Larvae, especially in the later stages, may also be provided solid food, such as trophic eggs, pieces of prey, and seeds brought by workers. The larvae grow through a series of four or five moults and enter the pupal stage. The pupa has the appendages free and not fused to the body as in a butterfly pupa. The differentiation into queens and workers (which are both female), and different castes of workers, is influenced in some species by the nutrition the larvae obtain. Genetic influences and the control of gene expression by the developmental environment are complex and the determination of caste continues to be a subject of research. Winged male ants, called drones (termed "aner" in old literature), emerge from pupae along with the usually winged breeding females. Some species, such as army ants, have wingless queens. Larvae and pupae need to be kept at fairly constant temperatures to ensure proper development, and so often are moved around among the various brood chambers within the colony. A new ergate spends the first few days of its adult life caring for the queen and young. She then graduates to digging and other nest work, and later to defending the nest and foraging. These changes are sometimes fairly sudden, and define what are called temporal castes. Such age-based task-specialization or polyethism has been suggested as having evolved due to the high casualties involved in foraging and defence, making it an acceptable risk only for ants who are older and likely to die sooner from natural causes. In the Brazilian ant Forelius pusillus, the nest entrance is closed from the outside to protect the colony from predatory ant species at sunset each day. About one to eight workers seal the nest entrance from the outside and they have no chance of returning to the nest and are in effect sacrificed. Whether these seemingly suicidal workers are older workers has not been determined. Ant colonies can be long-lived. The queens can live for up to 30 years, and workers live from 1 to 3 years. Males, however, are more transitory, being quite short-lived and surviving for only a few weeks. Ant queens are estimated to live 100 times as long as solitary insects of a similar size. Ants are active all year long in the tropics; however, in cooler regions, they survive the winter in a state of dormancy known as hibernation. The forms of inactivity are varied and some temperate species have larvae going into the inactive state (diapause), while in others, the adults alone pass the winter in a state of reduced activity. Reproduction A wide range of reproductive strategies have been noted in ant species. Females of many species are known to be capable of reproducing asexually through thelytokous parthenogenesis. Secretions from the male accessory glands in some species can plug the female genital opening and prevent females from re-mating. Most ant species have a system in which only the queen and breeding females have the ability to mate. Contrary to popular belief, some ant nests have multiple queens, while others may exist without queens. Workers with the ability to reproduce are called "gamergates" and colonies that lack queens are then called gamergate colonies; colonies with queens are said to be queen-right. Drones can also mate with existing queens by entering a foreign colony, such as in army ants. When the drone is initially attacked by the workers, it releases a mating pheromone. If recognized as a mate, it will be carried to the queen to mate. Males may also patrol the nest and fight others by grabbing them with their mandibles, piercing their exoskeleton and then marking them with a pheromone. The marked male is interpreted as an invader by worker ants and is killed. Most ants are univoltine, producing a new generation each year. During the species-specific breeding period, winged females and winged males, known to entomologists as alates, leave the colony in what is called a nuptial flight. The nuptial flight usually takes place in the late spring or early summer when the weather is hot and humid. Heat makes flying easier and freshly fallen rain makes the ground softer for mated queens to dig nests. Males typically take flight before the females. Males then use visual cues to find a common mating ground, for example, a landmark such as a pine tree to which other males in the area converge. Males secrete a mating pheromone that females follow. Males will mount females in the air, but the actual mating process usually takes place on the ground. Females of some species mate with just one male but in others they may mate with as many as ten or more different males, storing the sperm in their spermathecae. In Cardiocondyla elegans, workers may transport newly emerged queens to other conspecific nests where wingless males from unrelated colonies can mate with them, a behavioural adaptation that may reduce the chances of inbreeding. Mated females then seek a suitable place to begin a colony. There, they break off their wings using their tibial spurs and begin to lay and care for eggs. The females can selectively fertilise future eggs with the sperm stored to produce diploid workers or lay unfertilized haploid eggs to produce drones. The first workers to hatch, known as nanitics, are weaker and smaller than later workers but they begin to serve the colony immediately. They enlarge the nest, forage for food, and care for the other eggs. Species that have multiple queens may have a queen leaving the nest along with some workers to found a colony at a new site, a process akin to swarming in honeybees. Nests, colonies, and supercolonies The typical ant species has a colony occupying a single nest, housing one or more queens, where the brood is raised. There are however more than 150 species of ants in 49 genera that are known to have colonies consisting of multiple spatially separated nests. These polydomous (as opposed to monodomous) colonies have food and workers moving between the nests. Membership to a colony is identified by the response of worker ants which identify whether another individual belongs to their own colony or not. A signature cocktail of body surface chemicals (also known as cuticular hydrocarbons or CHCs) forms the so-called colony odor which other members can recognize. Some ant species appear to be less discriminating and in the Argentine ant Linepithema humile, workers carried from a colony anywhere in the southern US and Mexico are acceptable within other colonies in the same region. Similarly workers from colonies that have established in Europe are accepted by any other colonies within Europe but not by the colonies in the Americas. The interpretation of these observations has been debated and some have been termed these large populations as supercolonies while others have termed the poulations as unicolonial. Behaviour and ecology Communication Ants communicate with each other using pheromones, sounds, and touch. Since most ants live on the ground, they use the soil surface to leave pheromone trails that may be followed by other ants. In species that forage in groups, a forager that finds food marks a trail on the way back to the colony; this trail is followed by other ants, these ants then reinforce the trail when they head back with food to the colony. When the food source is exhausted, no new trails are marked by returning ants and the scent slowly dissipates. This behaviour helps ants deal with changes in their environment. For instance, when an established path to a food source is blocked by an obstacle, the foragers leave the path to explore new routes. If an ant is successful, it leaves a new trail marking the shortest route on its return. Successful trails are followed by more ants, reinforcing better routes and gradually identifying the best path. Ants use pheromones for more than just making trails. A crushed ant emits an alarm pheromone that sends nearby ants into an attack frenzy and attracts more ants from farther away. Several ant species even use "propaganda pheromones" to confuse enemy ants and make them fight among themselves. Pheromones are produced by a wide range of structures including Dufour's glands, poison glands and glands on the hindgut, pygidium, rectum, sternum, and hind tibia. Pheromones also are exchanged, mixed with food, and passed by trophallaxis, transferring information within the colony. This allows other ants to detect what task group (e.g., foraging or nest maintenance) other colony members belong to. In ant species with queen castes, when the dominant queen stops producing a specific pheromone, workers begin to raise new queens in the colony. Some ants produce sounds by stridulation, using the gaster segments and their mandibles. Sounds may be used to communicate with colony members or with other species. Defence Ants attack and defend themselves by biting and, in many species, by stinging often injecting or spraying chemicals. Bullet ants (Paraponera), located in Central and South America, are considered to have the most painful sting of any insect, although it is usually not fatal to humans. This sting is given the highest rating on the Schmidt sting pain index. The sting of jack jumper ants can be lethal for humans, and an antivenom has been developed for it. Fire ants, Solenopsis spp., are unique in having a venom sac containing piperidine alkaloids. Their stings are painful and can be dangerous to hypersensitive people. Formicine ants secrete a poison from their glands, made mainly of formic acid. Trap-jaw ants of the genus Odontomachus are equipped with mandibles called trap-jaws, which snap shut faster than any other predatory appendages within the animal kingdom. One study of Odontomachus bauri recorded peak speeds of between , with the jaws closing within 130 microseconds on average. The ants were also observed to use their jaws as a catapult to eject intruders or fling themselves backward to escape a threat. Before striking, the ant opens its mandibles extremely widely and locks them in this position by an internal mechanism. Energy is stored in a thick band of muscle and explosively released when triggered by the stimulation of sensory organs resembling hairs on the inside of the mandibles. The mandibles also permit slow and fine movements for other tasks. Trap-jaws also are seen in other ponerines such as Anochetus, as well as some genera in the tribe Attini, such as Daceton, Orectognathus, and Strumigenys, which are viewed as examples of convergent evolution. A Malaysian species of ant in the Camponotus cylindricus group has enlarged mandibular glands that extend into their gaster. If combat takes a turn for the worse, a worker may perform a final act of suicidal altruism by rupturing the membrane of its gaster, causing the content of its mandibular glands to burst from the anterior region of its head, spraying a poisonous, corrosive secretion containing acetophenones and other chemicals that immobilise small insect attackers. The worker subsequently dies. In addition to defence against predators, ants need to protect their colonies from pathogens. Secretions from the metapleural gland, unique to the ants, produce a complex range of chemicals including several with antibiotic properties. Some worker ants maintain the hygiene of the colony and their activities include undertaking or necrophoresis, the disposal of dead nest-mates. Oleic acid has been identified as the compound released from dead ants that triggers necrophoric behaviour in Atta mexicana while workers of Linepithema humile react to the absence of characteristic chemicals (dolichodial and iridomyrmecin) present on the cuticle of their living nestmates to trigger similar behaviour. Nests may be protected from physical threats such as flooding and overheating by elaborate nest architecture. Workers of Cataulacus muticus, an arboreal species that lives in plant hollows, respond to flooding by drinking water inside the nest, and excreting it outside. Camponotus anderseni, which nests in the cavities of wood in mangrove habitats, deals with submergence under water by switching to anaerobic respiration. Learning Many animals can learn behaviours by imitation, but ants may be the only group apart from mammals where interactive teaching has been observed. A knowledgeable forager of Temnothorax albipennis can lead a naïve nest-mate to newly discovered food by the process of tandem running. The follower obtains knowledge through its leading tutor. The leader is acutely sensitive to the progress of the follower and slows down when the follower lags and speeds up when the follower gets too close. Controlled experiments with colonies of Cerapachys biroi suggest that an individual may choose nest roles based on her previous experience. An entire generation of identical workers was divided into two groups whose outcome in food foraging was controlled. One group was continually rewarded with prey, while it was made certain that the other failed. As a result, members of the successful group intensified their foraging attempts while the unsuccessful group ventured out fewer and fewer times. A month later, the successful foragers continued in their role while the others had moved to specialise in brood care. Nest construction Complex nests are built by many ant species, but other species are nomadic and do not build permanent structures. Ants may form subterranean nests or build them on trees. These nests may be found in the ground, under stones or logs, inside logs, hollow stems, or even acorns. The materials used for construction include soil and plant matter, and ants carefully select their nest sites; Temnothorax albipennis will avoid sites with dead ants, as these may indicate the presence of pests or disease. They are quick to abandon established nests at the first sign of threats. The army ants of South America, such as the Eciton burchellii species, and the driver ants of Africa do not build permanent nests, but instead, alternate between nomadism and stages where the workers form a temporary nest (bivouac) from their own bodies, by holding each other together. Weaver ant (Oecophylla spp.) workers build nests in trees by attaching leaves together, first pulling them together with bridges of workers and then inducing their larvae to produce silk as they are moved along the leaf edges. Similar forms of nest construction are seen in some species of Polyrhachis. Formica polyctena, among other ant species, constructs nests that maintain a relatively constant interior temperature that aids in the development of larvae. The ants maintain the nest temperature by choosing the location, nest materials, controlling ventilation and maintaining the heat from solar radiation, worker activity and metabolism, and in some moist nests, microbial activity in the nest materials. Some ant species, such as those that use natural cavities, can be opportunistic and make use of the controlled micro-climate provided inside human dwellings and other artificial structures to house their colonies and nest structures. Cultivation of food Most ants are generalist predators, scavengers, and indirect herbivores, but a few have evolved specialised ways of obtaining nutrition. It is believed that many ant species that engage in indirect herbivory rely on specialized symbiosis with their gut microbes to upgrade the nutritional value of the food they collect and allow them to survive in nitrogen poor regions, such as rainforest canopies. Leafcutter ants (Atta and Acromyrmex) feed exclusively on a fungus that grows only within their colonies. They continually collect leaves which are taken to the colony, cut into tiny pieces and placed in fungal gardens. Ergates specialise in related tasks according to their sizes. The largest ants cut stalks, smaller workers chew the leaves and the smallest tend the fungus. Leafcutter ants are sensitive enough to recognise the reaction of the fungus to different plant material, apparently detecting chemical signals from the fungus. If a particular type of leaf is found to be toxic to the fungus, the colony will no longer collect it. The ants feed on structures produced by the fungi called gongylidia. Symbiotic bacteria on the exterior surface of the ants produce antibiotics that kill bacteria introduced into the nest that may harm the fungi. Navigation Foraging ants travel distances of up to from their nest and scent trails allow them to find their way back even in the dark. In hot and arid regions, day-foraging ants face death by desiccation, so the ability to find the shortest route back to the nest reduces that risk. Diurnal desert ants of the genus Cataglyphis such as the Sahara desert ant navigate by keeping track of direction as well as distance travelled. Distances travelled are measured using an internal pedometer that keeps count of the steps taken and also by evaluating the movement of objects in their visual field (optical flow). Directions are measured using the position of the sun. They integrate this information to find the shortest route back to their nest. Like all ants, they can also make use of visual landmarks when available as well as olfactory and tactile cues to navigate. Some species of ant are able to use the Earth's magnetic field for navigation. The compound eyes of ants have specialised cells that detect polarised light from the Sun, which is used to determine direction. These polarization detectors are sensitive in the ultraviolet region of the light spectrum. In some army ant species, a group of foragers who become separated from the main column may sometimes turn back on themselves and form a circular ant mill. The workers may then run around continuously until they die of exhaustion. Locomotion The female worker ants do not have wings and reproductive females lose their wings after their mating flights in order to begin their colonies. Therefore, unlike their wasp ancestors, most ants travel by walking. Some species are capable of leaping. For example, Jerdon's jumping ant (Harpegnathos saltator) is able to jump by synchronising the action of its mid and hind pairs of legs. There are several species of gliding ant including Cephalotes atratus; this may be a common trait among arboreal ants with small colonies. Ants with this ability are able to control their horizontal movement so as to catch tree trunks when they fall from atop the forest canopy. Other species of ants can form chains to bridge gaps over water, underground, or through spaces in vegetation. Some species also form floating rafts that help them survive floods. These rafts may also have a role in allowing ants to colonise islands. Polyrhachis sokolova, a species of ant found in Australian mangrove swamps, can swim and live in underwater nests. Since they lack gills, they go to trapped pockets of air in the submerged nests to breathe. Cooperation and competition Not all ants have the same kind of societies. The Australian bulldog ants are among the biggest and most basal of ants. Like virtually all ants, they are eusocial, but their social behaviour is poorly developed compared to other species. Each individual hunts alone, using her large eyes instead of chemical senses to find prey. Some species attack and take over neighbouring ant colonies. Extreme specialists among these slave-raiding ants, such as the Amazon ants, are incapable of feeding themselves and need captured workers to survive. Captured workers of enslaved Temnothorax species have evolved a counter-strategy, destroying just the female pupae of the slave-making Temnothorax americanus, but sparing the males (who do not take part in slave-raiding as adults). Ants identify kin and nestmates through their scent, which comes from hydrocarbon-laced secretions that coat their exoskeletons. If an ant is separated from its original colony, it will eventually lose the colony scent. Any ant that enters a colony without a matching scent will be attacked. Parasitic ant species enter the colonies of host ants and establish themselves as social parasites; species such as Strumigenys xenos are entirely parasitic and do not have workers, but instead, rely on the food gathered by their Strumigenys perplexa hosts. This form of parasitism is seen across many ant genera, but the parasitic ant is usually a species that is closely related to its host. A variety of methods are employed to enter the nest of the host ant. A parasitic queen may enter the host nest before the first brood has hatched, establishing herself prior to development of a colony scent. Other species use pheromones to confuse the host ants or to trick them into carrying the parasitic queen into the nest. Some simply fight their way into the nest. A conflict between the sexes of a species is seen in some species of ants with these reproducers apparently competing to produce offspring that are as closely related to them as possible. The most extreme form involves the production of clonal offspring. An extreme of sexual conflict is seen in Wasmannia auropunctata, where the queens produce diploid daughters by thelytokous parthenogenesis and males produce clones by a process whereby a diploid egg loses its maternal contribution to produce haploid males who are clones of the father. Relationships with other organisms Ants form symbiotic associations with a range of species, including other ant species, other insects, plants, and fungi. They also are preyed on by many animals and even certain fungi. Some arthropod species spend part of their lives within ant nests, either preying on ants, their larvae, and eggs, consuming the food stores of the ants, or avoiding predators. These inquilines may bear a close resemblance to ants. The nature of this ant mimicry (myrmecomorphy) varies, with some cases involving Batesian mimicry, where the mimic reduces the risk of predation. Others show Wasmannian mimicry, a form of mimicry seen only in inquilines. Aphids and other hemipteran insects secrete a sweet liquid called honeydew, when they feed on plant sap. The sugars in honeydew are a high-energy food source, which many ant species collect. In some cases, the aphids secrete the honeydew in response to ants tapping them with their antennae. The ants in turn keep predators away from the aphids and will move them from one feeding location to another. When migrating to a new area, many colonies will take the aphids with them, to ensure a continued supply of honeydew. Ants also tend mealybugs to harvest their honeydew. Mealybugs may become a serious pest of pineapples if ants are present to protect mealybugs from their natural enemies. Myrmecophilous (ant-loving) caterpillars of the butterfly family Lycaenidae (e.g., blues, coppers, or hairstreaks) are herded by the ants, led to feeding areas in the daytime, and brought inside the ants' nest at night. The caterpillars have a gland which secretes honeydew when the ants massage them. Some caterpillars produce vibrations and sounds that are perceived by the ants. A similar adaptation can be seen in Grizzled skipper butterflies that emit vibrations by expanding their wings in order to communicate with ants, which are natural predators of these butterflies. Other caterpillars have evolved from ant-loving to ant-eating: these myrmecophagous caterpillars secrete a pheromone that makes the ants act as if the caterpillar is one of their own larvae. The caterpillar is then taken into the ant nest where it feeds on the ant larvae. A number of specialized bacteria have been found as endosymbionts in ant guts. Some of the dominant bacteria belong to the order Hyphomicrobiales whose members are known for being nitrogen-fixing symbionts in legumes but the species found in ant lack the ability to fix nitrogen. Fungus-growing ants that make up the tribe Attini, including leafcutter ants, cultivate certain species of fungus in the genera Leucoagaricus or Leucocoprinus of the family Agaricaceae. In this ant-fungus mutualism, both species depend on each other for survival. The ant Allomerus decemarticulatus has evolved a three-way association with the host plant, Hirtella physophora (Chrysobalanaceae), and a sticky fungus which is used to trap their insect prey. Lemon ants make devil's gardens by killing surrounding plants with their stings and leaving a pure patch of lemon ant trees, (Duroia hirsuta). This modification of the forest provides the ants with more nesting sites inside the stems of the Duroia trees. Although some ants obtain nectar from flowers, pollination by ants is somewhat rare, one example being of the pollination of the orchid Leporella fimbriata which induces male Myrmecia urens to pseudocopulate with the flowers, transferring pollen in the process. One theory that has been proposed for the rarity of pollination is that the secretions of the metapleural gland inactivate and reduce the viability of pollen. Some plants have special nectar exuding structures, extrafloral nectaries, that provide food for ants, which in turn protect the plant from more damaging herbivorous insects. Species such as the bullhorn acacia (Acacia cornigera) in Central America have hollow thorns that house colonies of stinging ants (Pseudomyrmex ferruginea) who defend the tree against insects, browsing mammals, and epiphytic vines. Isotopic labelling studies suggest that plants also obtain nitrogen from the ants. In return, the ants obtain food from protein- and lipid-rich Beltian bodies. In Fiji Philidris nagasau (Dolichoderinae) are known to selectively grow species of epiphytic Squamellaria (Rubiaceae) which produce large domatia inside which the ant colonies nest. The ants plant the seeds and the domatia of young seedling are immediately occupied and the ant faeces in them contribute to rapid growth. Similar dispersal associations are found with other dolichoderines in the region as well. Another example of this type of ectosymbiosis comes from the Macaranga tree, which has stems adapted to house colonies of Crematogaster ants. Many plant species have seeds that are adapted for dispersal by ants. Seed dispersal by ants or myrmecochory is widespread, and new estimates suggest that nearly 9% of all plant species may have such ant associations. Often, seed-dispersing ants perform directed dispersal, depositing the seeds in locations that increase the likelihood of seed survival to reproduction. Some plants in arid, fire-prone systems are particularly dependent on ants for their survival and dispersal as the seeds are transported to safety below the ground. Many ant-dispersed seeds have special external structures, elaiosomes, that are sought after by ants as food. Ants can substantially alter rate of decomposition and nutrient cycling in their nest. By myrmecochory and modification of soil conditions they substantially alter vegetation and nutrient cycling in surrounding ecosystem. A convergence, possibly a form of mimicry, is seen in the eggs of stick insects. They have an edible elaiosome-like structure and are taken into the ant nest where the young hatch. Most ants are predatory and some prey on and obtain food from other social insects including other ants. Some species specialise in preying on termites (Megaponera and Termitopone) while a few Cerapachyinae prey on other ants. Some termites, including Nasutitermes corniger, form associations with certain ant species to keep away predatory ant species. The tropical wasp Mischocyttarus drewseni coats the pedicel of its nest with an ant-repellent chemical. It is suggested that many tropical wasps may build their nests in trees and cover them to protect themselves from ants. Other wasps, such as A. multipicta, defend against ants by blasting them off the nest with bursts of wing buzzing. Stingless bees (Trigona and Melipona) use chemical defences against ants. Flies in the Old World genus Bengalia (Calliphoridae) prey on ants and are kleptoparasites, snatching prey or brood from the mandibles of adult ants. Wingless and legless females of the Malaysian phorid fly (Vestigipoda myrmolarvoidea) live in the nests of ants of the genus Aenictus and are cared for by the ants. Fungi in the genera Cordyceps and Ophiocordyceps infect ants. Ants react to their infection by climbing up plants and sinking their mandibles into plant tissue. The fungus kills the ants, grows on their remains, and produces a fruiting body. It appears that the fungus alters the behaviour of the ant to help disperse its spores in a microhabitat that best suits the fungus. Strepsipteran parasites also manipulate their ant host to climb grass stems, to help the parasite find mates. A nematode (Myrmeconema neotropicum) that infects canopy ants (Cephalotes atratus) causes the black-coloured gasters of workers to turn red. The parasite also alters the behaviour of the ant, causing them to carry their gasters high. The conspicuous red gasters are mistaken by birds for ripe fruits, such as Hyeronima alchorneoides, and eaten. The droppings of the bird are collected by other ants and fed to their young, leading to further spread of the nematode. A study of Temnothorax nylanderi colonies in Germany found that workers parasitized by the tapeworm Anomotaenia brevis (ants are intermediate hosts, the definitive hosts are woodpeckers) lived much longer than unparasitized workers and had a reduced mortality rate, comparable to that of the queens of the same species, which live for as long as two decades. South American poison dart frogs in the genus Dendrobates feed mainly on ants, and the toxins in their skin may come from the ants. Army ants forage in a wide roving column, attacking any animals in that path that are unable to escape. In Central and South America, Eciton burchellii is the swarming ant most commonly attended by "ant-following" birds such as antbirds and woodcreepers. This behaviour was once considered mutualistic, but later studies found the birds to be parasitic. Direct kleptoparasitism (birds stealing food from the ants' grasp) is rare and has been noted in Inca doves which pick seeds at nest entrances as they are being transported by species of Pogonomyrmex. Birds that follow ants eat many prey insects and thus decrease the foraging success of ants. Birds indulge in a peculiar behaviour called anting that, as yet, is not fully understood. Here birds rest on ant nests, or pick and drop ants onto their wings and feathers; this may be a means to remove ectoparasites from the birds. Anteaters, aardvarks, pangolins, echidnas and numbats have special adaptations for living on a diet of ants. These adaptations include long, sticky tongues to capture ants and strong claws to break into ant nests. Brown bears (Ursus arctos) have been found to feed on ants. About 12%, 16%, and 4% of their faecal volume in spring, summer and autumn, respectively, is composed of ants. Relationship with humans Ants perform many ecological roles that are beneficial to humans, including the suppression of pest populations and aeration of the soil. The use of weaver ants in citrus cultivation in southern China is considered one of the oldest known applications of biological control. On the other hand, ants may become nuisances when they invade buildings or cause economic losses. In some parts of the world (mainly Africa and South America), large ants, especially army ants, are used as surgical sutures. The wound is pressed together and ants are applied along it. The ant seizes the edges of the wound in its mandibles and locks in place. The body is then cut off and the head and mandibles remain in place to close the wound. The large heads of the dinergates (soldiers) of the leafcutting ant Atta cephalotes are also used by native surgeons in closing wounds. Some ants have toxic venom and are of medical importance. The species include Paraponera clavata (tocandira) and Dinoponera spp. (false tocandiras) of South America and the Myrmecia ants of Australia. In South Africa, ants are used to help harvest the seeds of rooibos (Aspalathus linearis), a plant used to make a herbal tea. The plant disperses its seeds widely, making manual collection difficult. Black ants collect and store these and other seeds in their nest, where humans can gather them en masse. Up to half a pound (200 g) of seeds may be collected from one ant-heap. Although most ants survive attempts by humans to eradicate them, a few are highly endangered. These tend to be island species that have evolved specialized traits and risk being displaced by introduced ant species. Examples include the critically endangered Sri Lankan relict ant (Aneuretus simoni) and Adetomyrma venatrix of Madagascar. As food Ants and their larvae are eaten in different parts of the world. The eggs of two species of ants are used in Mexican escamoles. They are considered a form of insect caviar and can sell for as much as US$50 per kg going up to US$200 per kg (as of 2006) because they are seasonal and hard to find. In the Colombian department of Santander, hormigas culonas (roughly interpreted as "large-bottomed ants") Atta laevigata are toasted alive and eaten. In areas of India, and throughout Burma and Thailand, a paste of the green weaver ant (Oecophylla smaragdina) is served as a condiment with curry. Weaver ant eggs and larvae, as well as the ants, may be used in a Thai salad, yam (), in a dish called yam khai mot daeng () or red ant egg salad, a dish that comes from the Issan or north-eastern region of Thailand. Saville-Kent, in the Naturalist in Australia wrote "Beauty, in the case of the green ant, is more than skin-deep. Their attractive, almost sweetmeat-like translucency possibly invited the first essays at their consumption by the human species". Mashed up in water, after the manner of lemon squash, "these ants form a pleasant acid drink which is held in high favor by the natives of North Queensland, and is even appreciated by many European palates". In his First Summer in the Sierra, John Muir notes that the Digger Indians of California ate the tickling, acid gasters of the large jet-black carpenter ants. The Mexican Indians eat the repletes, or living honey-pots, of the honey ant (Myrmecocystus). As pests Some ant species are considered as pests, primarily those that occur in human habitations, where their presence is often problematic. For example, the presence of ants would be undesirable in sterile places such as hospitals or kitchens. Some species or genera commonly categorized as pests include the Argentine ant, immigrant pavement ant, yellow crazy ant, banded sugar ant, pharaoh ant, red wood ant, black carpenter ant, odorous house ant, red imported fire ant, and European fire ant. Some ants will raid stored food, some will seek water sources, others may damage indoor structures, some may damage agricultural crops directly or by aiding sucking pests. Some will sting or bite. The adaptive nature of ant colonies make it nearly impossible to eliminate entire colonies and most pest management practices aim to control local populations and tend to be temporary solutions. Ant populations are managed by a combination of approaches that make use of chemical, biological, and physical methods. Chemical methods include the use of insecticidal bait which is gathered by ants as food and brought back to the nest where the poison is inadvertently spread to other colony members through trophallaxis. Management is based on the species and techniques may vary according to the location and circumstance. In science and technology Observed by humans since the dawn of history, the behaviour of ants has been documented and the subject of early writings and fables passed from one century to another. Those using scientific methods, myrmecologists, study ants in the laboratory and in their natural conditions. Their complex and variable social structures have made ants ideal model organisms. Ultraviolet vision was first discovered in ants by Sir John Lubbock in 1881. Studies on ants have tested hypotheses in ecology and sociobiology, and have been particularly important in examining the predictions of theories of kin selection and evolutionarily stable strategies. Ant colonies may be studied by rearing or temporarily maintaining them in formicaria, specially constructed glass framed enclosures. Individuals may be tracked for study by marking them with dots of colours. The successful techniques used by ant colonies have been studied in computer science and robotics to produce distributed and fault-tolerant systems for solving problems, for example Ant colony optimization and Ant robotics. This area of biomimetics has led to studies of ant locomotion, search engines that make use of "foraging trails", fault-tolerant storage, and networking algorithms. As pets From the late 1950s through the late 1970s, ant farms were popular educational children's toys in the United States. Some later commercial versions use transparent gel instead of soil, allowing greater visibility at the cost of stressing the ants with unnatural light. In culture Anthropomorphised ants have often been used in fables and children's stories to represent industriousness and cooperative effort. They also are mentioned in religious texts. In the Book of Proverbs in the Bible, ants are held up as a good example of hard work and cooperation. Aesop did the same in his fable The Ant and the Grasshopper. In the Quran, Sulayman is said to have heard and understood an ant warning other ants to return home to avoid being accidentally crushed by Sulayman and his marching army., In parts of Africa, ants are considered to be the messengers of the deities. Some Native American mythology, such as the Hopi mythology, considers ants as the very first animals. Ant bites are often said to have curative properties. The sting of some species of Pseudomyrmex is claimed to give fever relief. Ant bites are used in the initiation ceremonies of some Amazon Indian cultures as a test of endurance. In Greek mythology, the goddess Athena turned the maiden Myrmex into an ant when the latter claimed to have invented the plough, when in fact it was Athena's own invention. Ant society has always fascinated humans and has been written about both humorously and seriously. Mark Twain wrote about ants in his 1880 book A Tramp Abroad. Some modern authors have used the example of the ants to comment on the relationship between society and the individual. Examples are Robert Frost in his poem "Departmental" and T. H. White in his fantasy novel The Once and Future King. The plot in French entomologist and writer Bernard Werber's Les Fourmis science-fiction trilogy is divided between the worlds of ants and humans; ants and their behaviour is described using contemporary scientific knowledge. H.G. Wells wrote about intelligent ants destroying human settlements in Brazil and threatening human civilization in his 1905 science-fiction short story, The Empire of the Ants. In more recent times, animated cartoons and 3-D animated films featuring ants have been produced including Antz, A Bug's Life, The Ant Bully, The Ant and the Aardvark, Ferdy the Ant and Atom Ant. Renowned myrmecologist E. O. Wilson wrote a short story, "Trailhead" in 2010 for The New Yorker magazine, which describes the life and death of an ant-queen and the rise and fall of her colony, from an ants' point of view. The French neuroanatomist, psychiatrist and eugenicist Auguste Forel believed that ant societies were models for human society. He published a five volume work from 1921 to 1923 that examined ant biology and society. In the early 1990s, the video game SimAnt, which simulated an ant colony, won the 1992 Codie award for "Best Simulation Program". Ants also are quite popular inspiration for many science-fiction insectoids, such as the Formics of Ender's Game, the Bugs of Starship Troopers, the giant ants in the films Them! and Empire of the Ants, Marvel Comics' super hero Ant-Man, and ants mutated into super-intelligence in Phase IV. In computer strategy games, ant-based species often benefit from increased production rates due to their single-minded focus, such as the Klackons in the Master of Orion series of games or the ChCht in Deadlock II. These characters are often credited with a hive mind, a common misconception about ant colonies.

Arbitration, in the context of the law of the United States, is a form of alternative dispute resolution. Specifically, arbitration is an alternative to litigation through which the parties to a dispute agree to submit their respective evidence and legal arguments to a neutral third party (the arbitrator(s) or arbiter(s)) for resolution. In practice arbitration is generally used as a substitute for litigation, particularly when the judicial process is perceived as too slow, expensive or biased. In some contexts, an arbitrator may be described as an umpire. Arbitration in the United States' most overarching clause is the Federal Arbitration Act (officially the United States Arbitration Act of 1925, commonly referred to as the FAA). The Act stipulates that arbitration in a majority of instances is legal when both parties, either after or prior to the arising of a dispute, agree to the arbitration. The Supreme Court has taken a pro-arbitration stance across most but not all cases, although the federal government, most recently in 2022, has passed certain exemptions to arbitration agreements. States are also generally prohibited from passing their own laws which the Supreme Court and other federal courts believe limit or discriminate against arbitration. The practice of arbitration, especially "forced" arbitration clauses between workers/consumers and large companies or organizations, has been gaining a growing amount of scrutiny from both the general public and trial lawyers. Arbitration clauses face various challenges to enforcement, and clauses are unenforceable in the United States when a dispute which falls under the scope of an arbitration clause pertains to sexual harassment or assault. History Agreements to arbitrate were not enforceable at common law. This rule has been traced back to dictum by Lord Coke in Vynor’s Case, 8 Co. Rep. 81b, 77 Eng. Rep. 597 (1609), that agreements to arbitrate were revocable by either party. During the Industrial Revolution, merchants became increasingly opposed to this rule. They argued that too many valuable business relationships were being destroyed through years of expensive adversarial litigation, in courts whose rules differed significantly from the informal norms and conventions of businesspeople. Arbitration was promoted as being faster, less adversarial, and cheaper. The result was the New York Arbitration Act of 1920, followed by the United States Arbitration Act of 1925 (now known as the Federal Arbitration Act). Both made agreements to arbitrate valid and enforceable (unless one party could show fraud or unconscionability or some other ground for rescission which undermined the validity of the entire contract). Due to the subsequent judicial expansion of the meaning of interstate commerce, the Supreme Court reinterpreted the FAA in a series of cases in the 1980s and 1990s to cover almost the full scope of interstate commerce. In the process, the Court held that the FAA preempted many state laws covering arbitration, some of which had been passed by state legislatures to protect their workers and consumers against powerful business interests. Starting in 1991 with the Gilmer decision arbitration expanded dramatically in the employment context, growing from 2.1 percent of employees subject to mandatory arbitration clauses in 1992 to 53.9% in 2017. Types of Arbitration Commercial and other forms of contract arbitration Since commercial arbitration is based upon either contract law or the law of treaties, the agreement between the parties to submit their dispute to arbitration is a legally binding contract. All arbitral decisions are considered to be "final and binding". This does not, however, void the requirements of law. Any dispute not excluded from arbitration by virtue of law (for example, criminal proceedings) may be submitted to arbitration. Furthermore, arbitration agreements can only bind parties who have agreed, expressly or impliedly, to arbitrate, and parties cannot be required to submit to an arbitration process if they have not previously "agreed so to submit". It is only through the advance agreement of the parties that the arbitrator derives [any] authority to resolve disputes. Arbitration cannot bind non-signatories to an arbitration contract, even if those non-signatories later become involved with a signatory to a contract by accident (usually through the commission of a tort). However, third-party non-signatories can be bound by arbitration agreements based on theories of estoppel, agency relationships with a party, assumption of the contract containing the arbitration agreement, third-party beneficiary status under the contract, or piercing the corporate veil. The question of whether two parties have actually agreed to arbitrate any disputes is one for judicial determination, because if the parties have not agreed to arbitrate then the arbitrator would have no authority. Where there is an arbitration agreement, doubts concerning "the scope of arbitrable issues should be resolved in favor of arbitration", but issues regarding whether a claim falls within the scope of arbitrable issues is a judicial matter, unless the parties have expressly agreed that the arbitrator may decide the scope of his or her own authority. Most courts hold that general arbitration clauses, such as an agreement to refer to arbitration any dispute "arising from" or "related to" a particular contract, do not authorize an arbitrator to determine whether a particular issue arises from or relates to the contract concerned. A minority view embraced by some courts is that this broad language can evidence the parties' clear and unmistakable intention to delegate the resolution of all issues to the arbitrator, including issues regarding arbitrability. Labor arbitration Arbitration may be used as a means of resolving labor disputes, an alternative to strikes and lockouts. Labor arbitration comes in two varieties: interest arbitration, which provides a method for resolving disputes about the terms to be included in a new contract when the parties are unable to agree, and grievance arbitration, which provides a method for resolving disputes over the interpretation and application of a collective bargaining agreement. Arbitration has also been used as a means of resolving labor disputes for more than a century. Labor organizations in the United States, such as the National Labor Union, called for arbitration as early as 1866 as an alternative to strikes to resolve disputes over the wages, benefits and other rights that workers would enjoy. Interest arbitration Governments have relied on arbitration to resolve particularly large labor disputes, such as the Coal Strike of 1902. This type of arbitration, wherein a neutral arbitrator decides the terms of the collective bargaining agreement, is commonly known as interest arbitration. The United Steelworkers of America adopted an elaborate form of interest arbitration, known as the Experimental Negotiating Agreement, in the 1970s as a means of avoiding the long and costly strikes that had made the industry vulnerable to foreign competition. Major League Baseball uses a variant of interest arbitration, in which an arbitrator chooses between the two sides' final offers, to set the terms for contracts for players who are not eligible for free agency. Interest arbitration is now most frequently used by public employees who have no right to strike (for example, law enforcement and firefighters). Grievance arbitration Unions and employers have also employed arbitration to resolve employee and union grievances arising under a collective bargaining agreement. The Amalgamated Clothing Workers of America made arbitration a central element of the Protocol of Peace it negotiated with garment manufacturers in the second decade of the twentieth century. Grievance arbitration became even more popular during World War II, when most unions had adopted a no-strike pledge. The War Labor Board, which attempted to mediate disputes over contract terms, pressed for inclusion of grievance arbitration in collective bargaining agreements. The Supreme Court subsequently made labor arbitration a key aspect of federal labor policy in three cases which came to be known as the Steelworkers' Trilogy. The Court held that grievance arbitration was a preferred dispute resolution technique and that courts could not overturn arbitrators' awards unless the award does not draw its essence from the collective bargaining agreement. State and federal statutes may allow vacating an award on narrow grounds (e.g., fraud). These protections for arbitrator awards are premised on the union-management system, which provides both parties with due process. Due process in this context means that both parties have experienced representation throughout the process, and that the arbitrators practice only as neutrals. See National Academy of Arbitrators. Securities arbitration In the United States securities industry, arbitration has long been the preferred method of resolving disputes between brokerage firms, and between firms and their customers. The arbitration process operates under its own rules, as defined by contract. Securities arbitrations are held primarily by the Financial Industry Regulatory Authority. The securities industry uses pre-dispute arbitration agreements, through which the parties agree to arbitrate their disputes before any such dispute arises. Those agreements were upheld by the United States Supreme Court in Shearson v. MacMahon, 482 U.S. 220 (1987) and today nearly all disputes involving brokerage firms, other than Securities class action claims, are resolved in arbitration. The SEC has come under fire from members of the Senate Judiciary Committee for not fulfilling statutory duty to protect individual investors, because all brokers require arbitration, and arbitration does not provide a court-supervised discovery process, require arbitrators to follow rules of evidence or result in written opinions establishing precedence, or case law, or provide the efficiency gains it once did. Arbitrator selection bias, hidden conflicts of interest, and a case where an arbitration panel refused to follow instructions handed down from a judge, were also raised as issues. Judicial arbitration Some state court systems have promulgated court-ordered arbitration; family law (particularly child custody) is the most prominent example. Judicial arbitration is often merely advisory dispute resolution technique, serving as the first step toward resolution, but not binding either side and allowing for trial de novo. Litigation attorneys present their side of the case to an independent tertiary lawyer, who issues an opinion on settlement. Should the parties in question decide to continue to dispute resolution process, there can be some sanctions imposed from the initial arbitration per terms of the contract. Arbitration clauses The federal government has expressed a policy in support of arbitration clauses, because they reduce the burden on court systems to resolve disputes. This support is found in the Federal Arbitration Act, (FAA) which permits compulsory and binding arbitration, under which parties give up the right to appeal an arbitrator's decision to a court. In Prima Paint Corp. v. Flood & Conklin Mfg. Co., the U.S. Supreme Court established the "separability principle", under which enforceability of a contract must be challenged in arbitration before any court action, unless the arbitration clause itself has been challenged. Today, mandatory arbitration clauses are widespread in the United States, including by 15 of the largest 20 U.S. credit card issuers, 7 of the 8 largest cell phone companies, and 2 out of 3 major bike sharing companies in Seattle. Arbitration clauses can be enforceable if "signed" electronically, though California courts have stated that a handwritten signature to an arbitration agreement is easier to enforce than one done electronically. The FAA has also been interpreted to preempt and invalidate state laws which prevent or discriminate against the enforcement of arbitration agreements. In one such case in 2023, which overruled California Assembly Bill 51, the Ninth Circuit Court of Appeals found that California's bill placed restrictions on the "broad national policy" favoring arbitration agreements. Similar fates have been bestowed upon legislation in New Jersey, New York, and Washington state which attempted to reduce the scope of arbitration clauses. In insurance law, arbitration is complicated by the fact that insurance is regulated at the state level under the McCarran–Ferguson Act. From a federal perspective, however, a circuit court ruling has determined that McCarran-Ferguson requires a state statute rather than administrative interpretations. The Missouri Department of Insurance attempted to block a binding arbitration agreement under its state authority, but since this action was based only on a policy of the department and not on a state statute, the United States district court found that the Department of Insurance did not have the authority to invalidate the arbitration agreement. In AT&T Mobility v. Concepcion (2011), the Supreme Court upheld an arbitration clause in a consumer standard form contract which waived the right to a lawsuit and class action. However, this clause was relatively generous in that the business paid all fees unless the action was determined to be frivolous and a small-claims court action remained available; these types of protections are recommended for the contract to remain enforceable and not unconscionable. The Supreme Court has also ruled that questions on whether an arbitration clause should be enforced at all permits litigation involving the rest of the case to be stayed. In 2023's Coinbase v. Bielski, the court ruled that federal district courts must stay proceedings involving a case during an arbitration appeal on such case. Arbitration clauses can also be written in a manner which excludes certain disputes from being required to be sent to arbitration. Motions to compel arbitration involving excluded disputes then on would not be honored, as seen in a 2023 ruling made by the Ninth Circuit via one of its judicial panels. In such ruling, the casino firm Saipan included an arbitration agreement which exempted licensing claims from being subject to mandatory arbitration. Opt out provisions Some arbitration clauses in the United States offer opportunities for parties to opt out of the arbitration agreement and not be subject to it. Many companies utilize opt out clauses within their arbitration agreements, most often giving 30 or 60 days for consumers in contracts between consumers and companies to either send a rejection notice by mail or by email. Including an opt out provision has been found to improve the likelihood of a contract to be found conscionable. In Hopkins v. World Acceptance Corp, a case cited in Ferrara v. Luxottica, failure to opt out of an arbitration agreement dilutes the ability to combat a motion to compel arbitration. Many credit card companies which have arbitration agreements allow card signers to opt out, although company procedures may make it difficult for consumers to exercise that option. Prohibitions on arbitration Challenges to clause enforcement Determination of validity Although properly drafted arbitration clauses are generally valid, they are subject to challenge in court for compliance with laws and public policy. Arbitration clauses may potentially be challenged as unconscionable and, therefore, unenforceable. Typically, the validity of an arbitration clause is decided by a court rather than an arbitrator. However, if the validity of the entire arbitration agreement is in dispute, then the issue is decided by the arbitrators in the first instance. This is known as the principle of separability. For example, in Rent-A-Center, West, Inc. v. Jackson, the Supreme Court of the United States held that "under the FAA, where an agreement to arbitrate includes an agreement that the arbitrator will determine the enforceability of the agreement, if a party challenges specifically the enforceability of that particular agreement, the district court considers the challenge, but if a party challenges the enforceability of the agreement as a whole, the challenge is for the arbitrator." In other words, the law typically allows federal courts to decide these types of "gateway" or validity questions, but the Supreme Court ruled that since Jackson targeted the entire contract rather than a specific clause, the arbitrator decided the validity. Public Citizen, an advocacy organization opposed to the enforcement of pre-dispute arbitration agreements, characterized the decision negatively: "the court said that companies can write their contracts so that the companies' own arbitrator decides whether it's fair to submit a case to that arbitrator." Arbitration clauses must also further provide a clear procedure, and confusion and/or ambiguity in an arbitration clause can also cause such clause to be struck down. One example of this phenomenon occurred in a lawsuit against SoLo Funds, where a Philadelphia federal judge ruled that because the app did not make clear its arbitration requirements, the clause was unconscionable and SoLo's bid to compel arbitration was not granted. Ambiguity-related nullifications of arbitration agreements further extend to proof of agreement between the parties, as in Romano v. BCBSM, Blue Cross Blue Shield of Michigan failed to compel arbitration against a former employee in June 2023 after US district judge George Caram Steeh III ruled that the online application process failed to adequately provide the employee notice of the arbitration agreement he would otherwise be bound to. Modification of the arbitration clause A significant challenge to arbitrate agreements arose out of South Carolina through the case Hooters v. Phillips. In the 1999 case, a federal district court found that Hooters modified its dispute resolution rules in 1996 to be unfair enough that the court held that the agreement was unconscionable, partly due to Hooters requiring that all of the arbitrators in dispute resolution cases be selected from a list pre-approved by the company, which included Hooters managers. In April of 2022, the Court of Appeals for the Fourth Circuit found that in Coady v. Nationwide Motor Sales, because Nationwide Motor Sales' contract enabled them to be the sole party permitted to modify the contract that Coady signed. Citing Hooters v. Phillips, the court expressed when an employer has the ability “in whole or in part” to modify the arbitration provision without notice to its employees. California's Court of Appeal reached a similar conclusion in Peleg v. Neiman Marcus, in which a unilateral modification to an arbitration agreement invalidated the clause. Another instance of modified arbitration clauses causing it to be overturned was found in a privacy-related dispute between Amazon and its drivers who work under the company's Amazon Flex service. Amazon Flex drivers, who filed a class action lawsuit claiming that the company spied on private Facebook conversations, alleged that the updated 2019 terms related to Amazon Flex were not delivered properly to them, and that the 2016 terms, which did not include an arbitration clause, should apply. Ultimately, the Ninth Circuit decided that since Amazon was the party compelling arbitration, the burden of proof was on Amazon to prove that its flex drivers received notice of the 2019 updated terms, and that arbitration should not be compelled. Waiving the right to arbitrate Some courts have found that parties can waive their right to compel arbitration through various forms of actions. In California, as demonstrated by Davis v. Shiekh Shoes and Espinoza v. Superior Court, a party wishing to compel arbitration though failing to pay arbitration fees in a timely manner waives their right to compel arbitration, and must resolve the dispute in court. More importantly, the Supreme Court found in Morgan v. Sundance that a party which does not compel arbitration when a valid clause exists waives its right to compel arbitration. Justice Elena Kagan, writing for the court's unanimous ruling in favor of hourly Taco Bell employee Robyn Morgan, found that the Eighth Circuit created "special rules" in which Morgan was compelled to arbitrate based on Sundance's prejudice (delay) of compelling arbitration. The opinion on a party waiving its right to compel arbitration if it had litigated extensively prior to the motion has been further confirmed in light of Davis and Espinoza when one of Bronx County's justices ruled in Worbes Corp v. Sebrow. Justice Fidel Gomez states that if a party who intended to compel arbitration brought a "substantive defense" before the court, served a trial notice, moved to depose a witness, or "interposed a counterclaim demanding money damages", that party would have waived its right to compel arbitration. Justice Gomez, however, clarified that such right would not be waived by a party if a defendant "had only defended its position and had not acted in a manner that waives the right to arbitrate". Unbearable arbitration fees Arbitration clauses can be void in instances where the costs of arbitration would be too high. In 1999's Shankle v. B-G Maintenance Management of Colorado, Inc, the 10th Circuit Court of Appeals refused to grant a motion to compel arbitration on the basis that the fees were too high for the plaintiff Matthew Shankle. The Texas Courts of Appeals found in 2022's Cont'l Homes of Texas v. Perez that due to unaffordable arbitration costs for the plaintiffs and the arbitration agreement not being an adequate remedy for litigation. Severability-related challenges In January 2023, a federal court in Delaware recommended that motions to compel arbitration which conflicted with the Employee Retirement Income Security Act of 1974 not be honored in Burnett et al. v. Prudent Financial Services LLC, et al. (C.A. No. 22-270-RGA-JLH). Presiding magistrate judge Jennifer Hall interpreted that based on recent action by the Supreme Court and other federal courts, not every provision within the arbitration agreement should be validated. Additionally, Judge Hall prospected that entire arbitration agreements could become invalid if a single provision is found to be unenforceable by a court. The notion of a single unconscionable provision invalidating the arbitration agreement, even if such provision was outside of the arbitration-related clauses of a contract, was expanded the following June when a California court ruled in Alberto v. Cambrian Homecare that a confidentiality agreement which prohibited discussing compensation and salary information, and threatened litigation and the collection of attorneys fees, was unenforceable and also declared the arbitration agreement unenforceable. Other challenges In 2014's Atalese v. U.S. Legal Services Group, L.P, the Supreme Court of New Jersey ruled that arbitration clauses must have a valid jury trial waiver, which the court saw as a constitutional right which must be explicitly waived in a contract, in order to be effective, a position reaffirmed by Pennsylvania's Superior Court in 2022's Chiluti v. Uber. A Pennsylvania appeals court in Philadelphia ruled in March 2023 that parents cannot bind their children to arbitration agreements over injuries, in a lawsuit between parents and a local trampoline park. Transportation workers exemption The Federal Arbitration Act also explicitly provides that workers involved in transportation are exempt from arbitration agreements, which the Supreme Court unanimously reaffirmed in various cases, with one notable example being 2022's Southwest Airlines v. Saxon. This, however, does not apply to drivers working for Uber and other ridesharing services. Acts of Congress Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act In 2022, Congress passed the Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act (EFASASHA or EFAA), which excludes these types of complaints from arbitration clauses. Congress also included a ban on class action waivers for claims covered under the act. Under the law, claims which are filed after March 3, 2022 and fall under the scope of EFAA shall have agreements to submit disputes to binding arbitration and class action waivers within contracts signed deemed unenforceable for the entire case, though the law allows for claimants to have a case decided by binding arbitration if the plaintiff wishes upon filing. The law was championed by Gretchen Carlson, a former Fox News host sexually harassed for many years by then CEO Roger Ailes; she also opposed the use of non-disclosure agreements to shield perpetrators. The law was introduced by Illinois House Democrat Cheri Bustos as HR 4445, and passed the House of Representatives by a 335-97 vote, with all no votes coming from Republicans. The EFAA passed the Senate with unanimous consent, and was signed into law by President Joe Biden on March 3, 2022. The law became effective immediately at signing. Some legal agencies raised concerns that the law could allow for claims attached to a sexual harassment or sexual assault dispute to bypass arbitration as well. These concerns were ultimately confirmed in February 2023, where New York federal judge Paul A. Engelmayer ruled in two lawsuits against the company Everyrealm that if at least one claim in a single case was an act of sexual assault or sexual harassment, the pre-dispute arbitration agreement was unenforceable and arbitration could not be compelled. Engelmayer's decision was rooted in the decision from Congress to directly amend the Federal Arbitration Act, and its actions to do so were indicative of its intention to prohibit the practice in entire cases which the EFAA covers; Engelmayer, however, clarified that the claim of sexual assault or harassment must be reasonable and that the EFAA does not enable implausible claims of sexual harassment to be used to "dodge" arbitration agreements. One month later, a California court ruling on a sexual harassment lawsuit filed against Tesla further confirmed the EFAA's ability to ban compelling arbitration in sexual harassment suits, and a second New York federal court earlier came to a similar conclusion in a case filed by an investment banker. Forced Arbitration Injustice Repeal Act The Forced Arbitration Injustice Repeal Act is a bill filed in every meeting of Congress since the 116th Congress which, if passed, contains provisions which ban arbitration agreements and class action waivers in cases between consumers and large companies, as well as employers and large companies. The bill is generally supported by the Democratic Party as well as Freedom Caucus member Matt Gaetz, though has usually been opposed by the Republican Party. In the 116th and 117th congresses, the bill passed the House but failed to pass the Senate; the bill has since been reintroduced in the 118th Congress by Democratic senators Sherrod Brown and Richard Blumenthal, and Democratic representative Hank Johnson. Protecting Older Americans Act The Protecting Older Americans Act is pending legislation first filed in the 118th Congress by South Carolina Republicans Lindsey Graham in the Senate and Nancy Mace in the House. The law would ban and overturn arbitration agreements in cases involving discrimination based on age. Rulings and actions by federal agencies Federal Student Loans In November 2022, the Department of Education and the office on Federal Student Aid passed new rules which included reinstating a ban on institutions participating in its Direct Loan Program from utilizing pre-dispute mandatory arbitration agreements and class action waivers in cases relating to Borrower Defense to Repayment. The new rules also require institutions to disclose their uses of arbitration to the Department and to provide certain records connected with any borrower defense claim against the school to the Department. The Department of Education stated its reasoning for the ban is that class action waivers and arbitration agreements are too complex for much of the general public to comprehend and that arbitration "rarely" gives favorable decisions to consumers.The rules become effective on July 1, 2023. Department of Labor The United States Department of Labor was noted in May 2023 by Bloomberg Law journalist Khorri Atkinson for its increased focus and hostility towards mandatory arbitration and its use by employers for violating Department of Labor rules. Solicitor of Labor Seema Nanda has stated that the Department will pursue more cases where employers are utilizing mandatory arbitration to commit violations of the Fair Labor Standards Act of 1938. Proceedings Various bodies of rules have been developed that can be used for arbitration proceedings. The rules to be followed by the arbitrator are specified by the agreement establishing the arbitration. Enforcement of award In some cases, a party may comply with an award voluntarily. However, in other cases a party will have to petition to receive a court judgment for enforcement through various means such as a writ of execution, garnishment, or lien. If the property is in another state, then a sister-state judgment (relying on the Full Faith and Credit Clause) can be received by filing to enforce the judgment in the state where the property is located. Vacatur Under the Federal Arbitration Act, courts can only vacate awards for limited reasons set out in statute with similar language in the state model Uniform Arbitration Act. The court will generally not change the arbitrator's findings of fact but will decide only whether the arbitrator was guilty of malfeasance, or whether the arbitrator exceeded the limits of his or her authority in the arbitral award or whether the award was made in manifest disregard of law or conflicts with well-established public policy.

Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) is a spectroanalytical procedure for the quantitative determination of chemical elements by free atoms in the gaseous state. Atomic absorption spectroscopy is based on absorption of light by free metallic ions. In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed. AAS can be used to determine over 70 different elements in solution, or directly in solid samples via electrothermal vaporization, and is used in pharmacology, biophysics, archaeology and toxicology research. Atomic emission spectroscopy was first used as an analytical technique, and the underlying principles were established in the second half of the 19th century by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff, both professors at the University of Heidelberg, Germany. The modern form of AAS was largely developed during the 1950s by a team of Australian chemists. They were led by Sir Alan Walsh at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Division of Chemical Physics, in Melbourne, Australia. Atomic absorption spectrometry has many uses in different areas of chemistry such as clinical analysis of metals in biological fluids and tissues such as whole blood, plasma, urine, saliva, brain tissue, liver, hair, muscle tissue. Atomic absorption spectrometry can be used in qualitative and quantitative analysis. Principles The technique makes use of the atomic absorption spectrum of a sample in order to assess the concentration of specific analytes within it. It requires standards with known analyte content to establish the relation between the measured absorbance and the analyte concentration and relies therefore on the [Beer–Lambert law]. Instrumentation In order to analyze a sample for its atomic constituents, it has to be atomized. The atomizers most commonly used nowadays are flames and electrothermal (graphite tube) atomizers. The atoms should then be irradiated by optical radiation, and the radiation source could be an element-specific line radiation source or a continuum radiation source. The radiation then passes through a monochromator in order to separate the element-specific radiation from any other radiation emitted by the radiation source, which is finally measured by a detector. Atomizers The used nowadays are spectroscopic flames and electrothermal atomizers. Other atomizers, such as glow-discharge atomization, hydride atomization, or cold-vapor atomization, might be used for special purposes. Flame atomizers The oldest and most commonly used atomizers in AAS are flames, principally the air-acetylene flame with a temperature of about 2300 °C and the nitrous oxide system (N2O)-acetylene flame with a temperature of about 2700 °C. The latter flame, in addition, offers a more reducing environment, being ideally suited for analytes with high affinity to oxygen. Liquid or dissolved samples are typically used with flame atomizers. The sample solution is aspirated by a pneumatic analytical nebulizer, transformed into an aerosol, which is introduced into a spray chamber, where it is mixed with the flame gases and conditioned in a way that only the finest aerosol droplets (< 10 μm) enter the flame. This conditioning process reduces interference, but only about 5% of the aerosolized solution reaches the flame because of it. On top of the spray chamber is a burner head that produces a flame that is laterally long (usually 5–10 cm) and only a few mm deep. The radiation beam passes through this flame at its longest axis, and the flame gas flow-rates may be adjusted to produce the highest concentration of free atoms. The burner height may also be adjusted, so that the radiation beam passes through the zone of highest atom cloud density in the flame, resulting in the highest sensitivity. The processes in a flame include the stages of desolvation (drying) in which the solvent is evaporated and the dry sample nano-particles remain, vaporization (transfer to the gaseous phase) in which the solid particles are converted into gaseous molecule, atomization in which the molecules are dissociated into free atoms, and ionization where (depending on the ionization potential of the analyte atoms and the energy available in a particular flame) atoms may be in part converted to gaseous ions. Each of these stages includes the risk of interference in case the degree of phase transfer is different for the analyte in the calibration standard and in the sample. Ionization is generally undesirable, as it reduces the number of atoms that are available for measurement, i.e., the sensitivity. In flame AAS a steady-state signal is generated during the time period when the sample is aspirated. This technique is typically used for determinations in the mg L−1 range, and may be extended down to a few μg L−1 for some elements. Electrothermal atomizers Electrothermal AAS (ET AAS) using graphite tube atomizers was pioneered by Boris V. L’vov at the Saint Petersburg Polytechnical Institute, Russia, since the late 1950s, and investigated in parallel by Hans Massmann at the Institute of Spectrochemistry and Applied Spectroscopy (ISAS) in Dortmund, Germany. Although a wide variety of graphite tube designs have been used over the years, the dimensions nowadays are typically 20–25 mm in length and 5–6 mm inner diameter. With this technique liquid/dissolved, solid and gaseous samples may be analyzed directly. A measured volume (typically 10–50 μL) or a weighed mass (typically around 1 mg) of a solid sample are introduced into the graphite tube and subject to a temperature program. This typically consists of stages, such as drying – the solvent is evaporated; pyrolysis – the majority of the matrix constituents are removed; atomization – the analyte element is released to the gaseous phase; and cleaning – eventual residues in the graphite tube are removed at high temperature. The graphite tubes are heated via their ohmic resistance using a low-voltage high-current power supply; the temperature in the individual stages can be controlled very closely, and temperature ramps between the individual stages facilitate separation of sample components. Tubes may be heated transversely or longitudinally, where the former ones have the advantage of a more homogeneous temperature distribution over their length. The so-called stabilized temperature platform furnace (STPF) concept, proposed by Walter Slavin, based on research of Boris L’vov, makes ET AAS essentially free from interference. The major components of this concept are atomization of the sample from a graphite platform inserted into the graphite tube (L’vov platform) instead of from the tube wall in order to delay atomization until the gas phase in the atomizer has reached a stable temperature; use of a chemical modifier in order to stabilize the analyte to a pyrolysis temperature that is sufficient to remove the majority of the matrix components; and integration of the absorbance over the time of the transient absorption signal instead of using peak height absorbance for quantification. In ET AAS a transient signal is generated, the area of which is directly proportional to the mass of analyte (not its concentration) introduced into the graphite tube. This technique has the advantage that any kind of sample, solid, liquid or gaseous, can be analyzed directly. Its sensitivity is 2–3 orders of magnitude higher than that of flame AAS, so that determinations in the low μg L−1 range (for a typical sample volume of 20 μL) and ng g−1 range (for a typical sample mass of 1 mg) can be carried out. It shows a very high degree of freedom from interferences, so that ET AAS might be considered the most robust technique available nowadays for the determination of trace elements in complex matrices. Specialized atomization techniques While flame and electrothermal vaporizers are the most common atomization techniques, several other atomization methods are utilized for specialized use. Glow-discharge atomization A glow-discharge device (GD) serves as a versatile source, as it can simultaneously introduce and atomize the sample. The glow discharge occurs in a low-pressure argon gas atmosphere between 1 and 10 torr. In this atmosphere lies a pair of electrodes applying a DC voltage of 250 to 1000 V to break down the argon gas into positively charged ions and electrons. These ions, under the influence of the electric field, are accelerated into the cathode surface containing the sample, bombarding the sample and causing neutral sample atom ejection through the process known as sputtering. The atomic vapor produced by this discharge is composed of ions, ground state atoms, and fraction of excited atoms. When the excited atoms relax back into their ground state, a low-intensity glow is emitted, giving the technique its name. The requirement for samples of glow discharge atomizers is that they are electrical conductors. Consequently, atomizers are most commonly used in the analysis of metals and other conducting samples. However, with proper modifications, it can be utilized to analyze liquid samples as well as nonconducting materials by mixing them with a conductor (e.g. graphite). Hydride atomization Hydride generation techniques are specialized in solutions of specific elements. The technique provides a means of introducing samples containing arsenic, antimony, selenium, bismuth, and lead into an atomizer in the gas phase. With these elements, hydride atomization enhances detection limits by a factor of 10 to 100 compared to alternative methods. Hydride generation occurs by adding an acidified aqueous solution of the sample to a 1% aqueous solution of sodium borohydride, all of which is contained in a glass vessel. The volatile hydride generated by the reaction that occurs is swept into the atomization chamber by an inert gas, where it undergoes decomposition. This process forms an atomized form of the analyte, which can then be measured by absorption or emission spectrometry. Cold-vapor atomization The cold-vapor technique is an atomization method limited only for the determination of mercury, due to it being the only metallic element to have a large vapor pressure at ambient temperature. Because of this, it has an important use in determining organic mercury compounds in samples and their distribution in the environment. The method initiates by converting mercury into Hg2+ by oxidation from nitric and sulfuric acids, followed by a reduction of Hg2+ with tin(II) chloride. The mercury, is then swept into a long-pass absorption tube by bubbling a stream of inert gas through the reaction mixture. The concentration is determined by measuring the absorbance of this gas at 253.7 nm. Detection limits for this technique are in the parts-per-billion range making it an excellent mercury detection atomization method. Radiation sources We have to distinguish between line source AAS (LS AAS) and continuum source AAS (CS AAS). In classical LS AAS, as it has been proposed by Alan Walsh, the high spectral resolution required for AAS measurements is provided by the radiation source itself that emits the spectrum of the analyte in the form of lines that are narrower than the absorption lines. Continuum sources, such as deuterium lamps, are only used for background correction purposes. The advantage of this technique is that only a medium-resolution monochromator is necessary for measuring AAS; however, it has the disadvantage that usually a separate lamp is required for each element that has to be determined. In CS AAS, in contrast, a single lamp, emitting a continuum spectrum over the entire spectral range of interest is used for all elements. Obviously, a high-resolution monochromator is required for this technique, as will be discussed later. Hollow cathode lamps Hollow cathode lamps (HCL) are the most common radiation source in LS AAS. Inside the sealed lamp, filled with argon or neon gas at low pressure, is a cylindrical metal cathode containing the element of interest and an anode. A high voltage is applied across the anode and cathode, resulting in an ionization of the fill gas. The gas ions are accelerated towards the cathode and, upon impact on the cathode, sputter cathode material that is excited in the glow discharge to emit the radiation of the sputtered material, i.e., the element of interest. In the majority of cases single element lamps are used, where the cathode is pressed out of predominantly compounds of the target element. Multi-element lamps are available with combinations of compounds of the target elements pressed in the cathode. Multi element lamps produce slightly less sensitivity than single element lamps and the combinations of elements have to be selected carefully to avoid spectral interferences. Most multi-element lamps combine a handful of elements, e.g.: 2 - 8. Atomic Absorption Spectrometers can feature as few as 1-2 hollow cathode lamp positions or in automated multi-element spectrometers, a 8-12 lamp positions may be typically available. Electrodeless discharge lamps Electrodeless discharge lamps (EDL) contain a small quantity of the analyte as a metal or a salt in a quartz bulb together with an inert gas, typically argon gas, at low pressure. The bulb is inserted into a coil that is generating an electromagnetic radio frequency field, resulting in a low-pressure inductively coupled discharge in the lamp. The emission from an EDL is higher than that from an HCL, and the line width is generally narrower, but EDLs need a separate power supply and might need a longer time to stabilize. Deuterium lamps Deuterium HCL or even hydrogen HCL and deuterium discharge lamps are used in LS AAS for background correction purposes. The radiation intensity emitted by these lamps decreases significantly with increasing wavelength, so that they can be only used in the wavelength range between 190 and about 320 nm. Continuum sources When a continuum radiation source is used for AAS, it is necessary to use a high-resolution monochromator, as will be discussed later. In addition, it is necessary that the lamp emits radiation of intensity at least an order of magnitude above that of a typical HCL over the entire wavelength range from 190 nm to 900 nm. A special high-pressure xenon short arc lamp, operating in a hot-spot mode has been developed to fulfill these requirements. Spectrometer As already pointed out above, there is a difference between medium-resolution spectrometers that are used for LS AAS and high-resolution spectrometers that are designed for CS AAS. The spectrometer includes the spectral sorting device (monochromator) and the detector. Spectrometers for LS AAS In LS AAS the high resolution that is required for the measurement of atomic absorption is provided by the narrow line emission of the radiation source, and the monochromator simply has to resolve the analytical line from other radiation emitted by the lamp. This can usually be accomplished with a band pass between 0.2 and 2 nm, i.e., a medium-resolution monochromator. Another feature to make LS AAS element-specific is modulation of the primary radiation and the use of a selective amplifier that is tuned to the same modulation frequency, as already postulated by Alan Walsh. This way any (unmodulated) radiation emitted for example by the atomizer can be excluded, which is imperative for LS AAS. Simple monochromators of the Littrow or (better) the Czerny-Turner design are typically used for LS AAS. Photomultiplier tubes are the most frequently used detectors in LS AAS, although solid state detectors might be preferred because of their better signal-to-noise ratio. Spectrometers for CS AAS When a continuum radiation source is used for AAS measurement it is indispensable to work with a high-resolution monochromator. The resolution has to be equal to or better than the half-width of an atomic absorption line (about 2 pm) in order to avoid losses of sensitivity and linearity of the calibration graph. The research with high-resolution (HR) CS AAS was pioneered by the groups of O’Haver and Harnly in the US, who also developed the (up until now) only simultaneous multi-element spectrometer for this technique. The breakthrough, however, came when the group of Becker-Ross in Berlin, Germany, built a spectrometer entirely designed for HR-CS AAS. The first commercial equipment for HR-CS AAS was introduced by Analytik Jena (Jena, Germany) at the beginning of the 21st century, based on the design proposed by Becker-Ross and Florek. These spectrometers use a compact double monochromator with a prism pre-monochromator and an echelle grating monochromator for high resolution. A linear charge-coupled device (CCD) array with 200 pixels is used as the detector. The second monochromator does not have an exit slit; hence the spectral environment at both sides of the analytical line becomes visible at high resolution. As typically only 3–5 pixels are used to measure the atomic absorption, the other pixels are available for correction purposes. One of these corrections is that for lamp flicker noise, which is independent of wavelength, resulting in measurements with very low noise level; other corrections are those for background absorption, as will be discussed later. Background absorption and background correction The relatively small number of atomic absorption lines (compared to atomic emission lines) and their narrow width (a few pm) make spectral overlap rare; there are only few examples known that an absorption line from one element will overlap with another. Molecular absorption, in contrast, is much broader, so that it is more likely that some molecular absorption band will overlap with an atomic line. This kind of absorption might be caused by un-dissociated molecules of concomitant elements of the sample or by flame gases. We have to distinguish between the spectra of di-atomic molecules, which exhibit a pronounced fine structure, and those of larger (usually tri-atomic) molecules that don't show such fine structure. Another source of background absorption, particularly in ET AAS, is scattering of the primary radiation at particles that are generated in the atomization stage, when the matrix could not be removed sufficiently in the pyrolysis stage. All these phenomena, molecular absorption and radiation scattering, can result in artificially high absorption and an improperly high (erroneous) calculation for the concentration or mass of the analyte in the sample. There are several techniques available to correct for background absorption, and they are significantly different for LS AAS and HR-CS AAS. Background correction techniques in LS AAS In LS AAS background absorption can only be corrected using instrumental techniques, and all of them are based on two sequential measurements: firstly, total absorption (atomic plus background), secondly, background absorption only. The difference of the two measurements gives the net atomic absorption. Because of this, and because of the use of additional devices in the spectrometer, the signal-to-noise ratio of background-corrected signals is always significantly inferior compared to uncorrected signals. It should also be pointed out that in LS AAS there is no way to correct for (the rare case of) a direct overlap of two atomic lines. In essence there are three techniques used for background correction in LS AAS: Deuterium background correction This is the oldest and still most commonly used technique, particularly for flame AAS. In this case, a separate source (a deuterium lamp) with broad emission is used to measure the background absorption over the entire width of the exit slit of the spectrometer. The use of a separate lamp makes this technique the least accurate one, as it cannot correct for any structured background. It also cannot be used at wavelengths above about 320 nm, as the emission intensity of the deuterium lamp becomes very weak. The use of deuterium HCL is preferable compared to an arc lamp due to the better fit of the image of the former lamp with that of the analyte HCL. Smith-Hieftje background correction This technique (named after their inventors) is based on the line-broadening and self-reversal of emission lines from HCL when high current is applied. Total absorption is measured with normal lamp current, i.e., with a narrow emission line, and background absorption after application of a high-current pulse with the profile of the self-reversed line, which has little emission at the original wavelength, but strong emission on both sides of the analytical line. The advantage of this technique is that only one radiation source is used; among the disadvantages are that the high-current pulses reduce lamp lifetime, and that the technique can only be used for relatively volatile elements, as only those exhibit sufficient self-reversal to avoid dramatic loss of sensitivity. Another problem is that background is not measured at the same wavelength as total absorption, making the technique unsuitable for correcting structured background. Zeeman-effect background correction An alternating magnetic field is applied at the atomizer (graphite furnace) to split the absorption line into three components, the π component, which remains at the same position as the original absorption line, and two σ components, which are moved to higher and lower wavelengths, respectively. Total absorption is measured without magnetic field and background absorption with the magnetic field on. The π component has to be removed in this case, e.g. using a polarizer, and the σ components do not overlap with the emission profile of the lamp, so that only the background absorption is measured. The advantages of this technique are that total and background absorption are measured with the same emission profile of the same lamp, so that any kind of background, including background with fine structure can be corrected accurately, unless the molecule responsible for the background is also affected by the magnetic field and using a chopper as a polariser reduces the signal to noise ratio. While the disadvantages are the increased complexity of the spectrometer and power supply needed for running the powerful magnet needed to split the absorption line. Background correction techniques in HR-CS AAS In HR-CS AAS background correction is carried out mathematically in the software using information from detector pixels that are not used for measuring atomic absorption; hence, in contrast to LS AAS, no additional components are required for background correction. Background correction using correction pixels It has already been mentioned that in HR-CS AAS lamp flicker noise is eliminated using correction pixels. In fact, any increase or decrease in radiation intensity that is observed to the same extent at all pixels chosen for correction is eliminated by the correction algorithm. This obviously also includes a reduction of the measured intensity due to radiation scattering or molecular absorption, which is corrected in the same way. As measurement of total and background absorption, and correction for the latter, are strictly simultaneous (in contrast to LS AAS), even the fastest changes of background absorption, as they may be observed in ET AAS, do not cause any problem. In addition, as the same algorithm is used for background correction and elimination of lamp noise, the background corrected signals show a much better signal-to-noise ratio compared to the uncorrected signals, which is also in contrast to LS AAS. Background correction using a least-squares algorithm The above technique can obviously not correct for a background with fine structure, as in this case the absorbance will be different at each of the correction pixels. In this case HR-CS AAS is offering the possibility to measure correction spectra of the molecule(s) that is (are) responsible for the background and store them in the computer. These spectra are then multiplied with a factor to match the intensity of the sample spectrum and subtracted pixel by pixel and spectrum by spectrum from the sample spectrum using a least-squares algorithm. This might sound complex, but first of all the number of di-atomic molecules that can exist at the temperatures of the atomizers used in AAS is relatively small, and second, the correction is performed by the computer within a few seconds. The same algorithm can actually also be used to correct for direct line overlap of two atomic absorption lines, making HR-CS AAS the only AAS technique that can correct for this kind of spectral interference.

Ajaccio (, , ; French: ; or ; , locally: ; ) is a French commune, prefecture of the department of Corse-du-Sud, and head office of the Collectivité territoriale de Corse (capital city of Corsica). It is also the largest settlement on the island. Ajaccio is located on the west coast of the island of Corsica, southeast of Marseille. The original city went into decline in the Middle Ages, but began to prosper again after the Genoese built a citadel in 1492, to the south of the earlier settlement. After the Corsican Republic was declared in 1755, the Genoese continued to hold several citadels, including Ajaccio, until the French took control of the island. The inhabitants of the commune are known as Ajacciens (men) or Ajacciennes (women). The most famous of these is Napoleon Bonaparte, who was born in Ajaccio in 1769, and whose ancestral home, the Maison Bonaparte, is now a museum. Other dedications to him in the city include Ajaccio Napoleon Bonaparte Airport. Toponymy Several hypotheses have been advanced as to the etymology of the name Ajaccio (Aiacciu in Corsican, Addiazzo on old documents). Among these, the most prestigious suggests that the city was founded by the Greek legendary hero Ajax and named after him. Other more realistic explanations are, for example, that the name could be related to the Tuscan agghiacciu meaning "sheep pens". Another explanation, supported by Byzantine sources from around the year 600 AD called the city Agiation which suggests a possible Greek origin for the word, agathè could mean "good luck" or "good mooring" (this was also the root of the name of the city of Agde). Geography Location Ajaccio is located on the west coast of the island of Corsica, southeast of Marseille. The commune occupies a sheltered position at the foot of wooded hills on the northern shore of the Gulf of Ajaccio between Gravona and the pointe de la Parata and includes the îles Sanguinaires (Bloody Islands). The harbour lies to the east of the original citadel below a hill overlooking a peninsula which protects the harbour in the south where the Quai de la Citadelle and the Jettée de la Citadelle are. The modern city not only encloses the entire harbour but takes up the better part of the Gulf of Ajaccio and in suburban form extends for some miles up the valley of the river Gravona. The flow from that river is nearly entirely consumed as the city's water supply. Many beaches and coves border its territory and the terrain is particularly rugged in the west where the highest point is . Urbanism Although the commune of Ajaccio has a large area (82.03 km2), only a small portion of this is urbanized. Therefore, the urban area of Ajaccio is located in the east of the commune on a narrow coastal strip forming a densely populated arc. The rest of the territory is natural with habitation of little importance and spread thinly. Suburbanization occurs north and east of the main urban area. The original urban core, close to the old marshy plain of Cannes was abandoned in favour of the current city which was built near the Punta della Lechia. It has undergone various improvements, particularly under Napoleon, who originated the two current major structural arteries (the Cours Napoleon oriented north–south and the Cours Grandval oriented east–west). Ajaccio experienced a demographic boom in the 1960s, which explains why 85% of dwellings are post-1949. This is reflected in the layout of the city which is marked by very large areas of low-rise buildings and concrete towers, especially on the heights (Les Jardins de l'Empereur) and in the north of the city - e.g. the waterfront, Les Cannes, and Les Salines. A dichotomy appears in the landscape between the old city and the imposing modern buildings. Ajaccio gives the image of a city built on two different levels. Climate The city has a Mediterranean climate which is Csa in the Köppen climate classification. The average annual sunshine is 2726 hours. There are important local climatic variations, especially with wind exposure and total precipitation, between the city centre, the airport, and the îles Sanguinaires. The annual average rainfall is at the Campo dell'Oro weather station (as per the chart) and at the Parata: the third-driest place in metropolitan France. The heat and dryness of summer are somewhat tempered by the proximity of the Mediterranean Sea except when the sirocco is blowing. In autumn and spring, heavy rain-storm episodes may occur. Winters are mild and snow is rare. Ajaccio is the French city which holds the record for the number of thunderstorms in the reference period 1971–2000 with an average of 39 thunderstorm days per year. On 14 September 2009, the city was hit by a tornado with an intensity of F1 on the Fujita scale. There was little damage except torn billboards, flying tiles, overturned cars, and broken windows but no casualties. Weather Data for Ajaccio Heraldry History Antiquity The city was not mentioned by the Greek geographer Ptolemy of Alexandria in the 2nd century AD despite the presence of a place called Ourkinion in the Cinarca area. It is likely that the city of Ajaccio had its first development at this time. The 2nd century was a period of prosperity in the Mediterranean basin (the Pax Romana) and there was a need for a proper port at the head of the several valleys that lead to the Gulf able to accommodate large ships. Some important underwater archaeological discoveries recently made of Roman ships tend to confirm this. Further excavations conducted recently led to the discovery of important early Christian remains suggest that an upwards reevaluation might be necessary of the size of Ajaccio city in Late Antiquity and the beginning of the Middle Ages. The city was in any case already significant enough to be the seat of a diocese, mentioned by Pope Gregory the Great in 591. The city was then further north than the location chosen later by the Genoese - in the location of the existing quarters of Castel Vecchio and Sainte-Lucie. The earliest certain written record of a settlement at Ajaccio with a name ancestral to its name was the exhortation in Epistle 77 written in 601AD by Gregory the great to the Defensor Boniface, one of two known rectors of the early Corsican church, to tell him not to leave Aléria and Adjacium without bishops. There is no earlier use of the term and Adjacium is not an attested Latin word, which probably means that it is a Latinization of a word in some other language. The Ravenna Cosmography of about 700 AD cites Agiation, which sometimes is taken as evidence of a prior Greek city, as -ion appears to be a Greek ending. There is, however, no evidence at all of a Greek presence on the west coast and the Ionians at Aléria on the east coast had been expelled by the Etruscans long before Roman domination. Ptolemy, who must come the closest to representing indigenous names, lists the Lochra River just south of a feature he calls the "sandy shore" on the southwest coast. If the shore is the Campo dell'Oro (Place of Gold) the Lochra would seem to be the combined mouth of the Gravona and Prunelli Rivers, neither one of which sounds like Lochra. North of there was a Roman city, Ourchinion. The western coastline was so distorted, however, that it is impossible to say where Adjacium was; certainly, he would have known its name and location if he had had any first-hand knowledge of the island and if in fact it was there. Ptolemy's Ourchinion is further north than Ajaccio and does not have the same name. It could be Sagone. The lack of correspondence between Ptolemaic and historical names known to be ancient has no defense except in the case of the two Roman colonies, Aleria and Mariana. In any case the population of the region must belong to Ptolemy's Tarabeni or Titiani people, neither of which are ever heard about again. Archaeological evidence The population of the city throughout the centuries maintained an oral tradition that it had originally been Roman. Travellers of the 19th century could point to the Hill of San Giovanni on the northwest shore of the Gulf of Ajaccio, which still had a cathedral said to have been the 6th-century seat of the Bishop of Ajaccio. The Castello Vecchio ("old castle"), a ruined citadel, was believed to be Roman but turned out to have Gothic features. The hill was planted with vines. The farmers kept turning up artifacts and terracotta funerary urns that seemed to be Roman. In the 20th century, the hill was covered over with buildings and became a part of downtown Ajaccio. In 2005 construction plans for a lot on the hill offered the opportunity to the Institut national de recherches archéologiques preventatives (Inrap) to excavate. They found the baptistry of a 6th-century cathedral and large amounts of pottery dated to the 6th and 7th centuries AD; in other words, an early Christian town. A cemetery had been placed over the old church. In it was a single Roman grave covered over with roof tiles bearing short indecipherable inscriptions. The finds of the previous century had included Roman coins. This is the only evidence so far of a Roman city continuous with the early Christian one. Medieval Genoese period It has been established that after the 8th century the city, like most other Corsican coastal communities, strongly declined and disappeared almost completely. Nevertheless, a castle and a cathedral were still in place in 1492 which last was not demolished until 1748. Towards the end of the 15th century, the Genoese were eager to assert their dominance in the south of the island and decided to rebuild the city of Ajaccio. Several sites were considered: the Pointe de la Parata (not chosen because it was too exposed to the wind), the ancient city (finally considered unsafe because of the proximity of the salt ponds), and finally the Punta della Lechia which was finally selected. Work began on the town on 21 April 1492 south of the Christian village by the Bank of Saint George at Genoa, who sent Cristoforo of Gandini, an architect, to build it. He began with a castle on Capo di Bolo, around which he constructed residences for several hundred people. The new city was essentially a colony of Genoa. The Corsicans were restricted from the city for some years. Nevertheless, the town grew rapidly and became the administrative capital of the province of Au Delà Des Monts (more or less the current Corse-du-Sud). Bastia remained the capital of the entire island. Although at first populated exclusively by the Genoese, the city slowly opened to the Corsicans while the Ajaccians, almost to the French conquest, were legally citizens of the Republic of Genoa and were happy to distinguish themselves from the insular paesani who lived mainly in Borgu, a suburb outside the city walls (the current rue Fesch was the main street). Attachment to France Ajaccio was occupied from 1553 to 1559 by the French, but it again fell to the Genoese after the Treaty of Cateau Cambresis in the latter year. Subsequently, the Republic of Genoa was strong enough to keep Corsica until 1755, the year Pasquale Paoli proclaimed the Corsican Republic. Paoli took most of the island for the republic, but he was unable to force Genoese troops out of the citadels of Saint-Florent, Calvi, Ajaccio, Bastia and Algajola. Leaving them there, he went on to build the nation, while the Republic of Genoa was left to ponder prospects and solutions. Their ultimate solution was to sell Corsica to France in 1768 and French troops of the Ancien Régime replaced Genoese ones in the citadels, including Ajaccio's. Corsica was formally annexed to France in 1780. Napoleon Napoleon Bonaparte (born as Napoleone di Buonaparte) was born at Ajaccio in the same year as the Battle of Ponte Novu, 1769. The Buonaparte family at the time had a modest four-story home in town (now a museum known as Maison Bonaparte) and a rarely used country home in the hills north of the city (now site of the Arboretum des Milelli). The father of the family, attorney Carlo di Buonaparte, was secretary to Pasquale Paoli during the Corsican Republic. After the defeat of Paoli, the Comte de Marbeuf began to meet with some leading Corsicans to outline the shape of the future and enlist their assistance. The Comte was among a delegation from Ajaccio in 1769, offered his loyalty and was appointed assessor. Marbeuf also offered Carlo di Buonaparte an appointment for one of his sons to the Military College of Brienne, but Napoleone did not speak French which was a requirement and he had to be at least ten years of age. There is a dispute concerning Napoleon's age because of this requirement; the emperor is known to have altered the civic records at Ajaccio concerning himself and it is possible that he was born in Corte in 1768 when his father was there on business. In any case Napoleon was sent to a school in Autun to learn basic French, then after a year went to Brienne from 1779 to 1784. At Brienne Napoleon concentrated on studies. He wrote a boyish history of Corsica. He did not share his father's views but held Pasquale Paoli in high esteem and was at heart a Corsican nationalist. The top students were encouraged to go into the artillery. After graduation and a brief sojourn at the Military School of Paris Napoleon applied for a second-lieutenancy in the artillery regiment of La Fère at Valence and after a time was given the position. Meanwhile, his father died and his mother was cast into poverty in Corsica, still having four children to support. Her only income was Napoleon's meager salary. The regiment was in Auxonne when the revolution broke out in the summer of 1789. Napoleon returned on leave to Ajaccio in October, became a Jacobin and began to work for the revolution. The National Assembly in Paris united Corsica to France and pardoned its exiles. Paoli returned in 1790 after 21 years and kissed the soil on which he stood. He and Napoleon met and toured the battlefield of Paoli's defeat. A national assembly at Orezza created the department of Corsica and Paoli was subsequently elected president. He commanded the national guard raised by Napoleon. After a brief return to his regiment Napoleon was promoted to first lieutenant and came home again on leave in 1791. All officers were recalled from leave in 1792, intervention threatened and war with Austria (Marie-Antoinette's homeland) began. Napoleon returned to Paris for review, was exonerated, then promoted to captain and given leave to escort his sister, a schoolgirl, back to Corsica at state expense. His family was prospering; his estate increased. Napoleon became a lieutenant-colonel in the Corsican National Guard. Paoli sent him off on an expedition to Sardinia, ordered by France, under Paolis's nephew but the nephew had secret orders from Paoli to make sure the expedition failed. Paoli was now a conservative, opposing the execution of the king and supporting an alliance with Great Britain. Returning from Sardinia Napoleon with his family and all his supporters were instrumental in getting Paoli denounced at the National Convention in Paris in 1793. Napoleon earned the hatred of the Paolists by pretending to support Paoli and then turning against him (payment, one supposes, for Sardinia). Paoli was convicted in absentia, a warrant was issued for his arrest (which could not be served) and Napoleon was dispatched to Corsica as Inspector General of Artillery to take the citadel of Ajaccio from the royalists who had held it since 1789. The Paolists combining with the royalists defeated the French in two pitched battles and Napoleon and his family went on the run, hiding by day, while the Paolists burned their estate. Napoleon and his mother, Laetitia, were taken out by ship in June 1793, by friends while two of the girls found refuge with other friends. They landed in Toulon with only Napoleon's pay for their support. The Bonapartes moved to Marseille but in August Toulon offered itself to the British and received the protection of a fleet under Admiral Hood. The Siege of Toulon began in September under revolutionary officers mainly untrained in the art of war. Napoleon happened to present socially one evening and during a casual conversation over a misplaced 24-pounder explained the value of artillery. Taken seriously he was allowed to bring up over 100 guns from coastal emplacements but his plan for the taking of Toulon was set aside as one incompetent officer superseded another. By December they decided to try his plan and made him a Colonel. Placing the guns at close range he used them to keep the British fleet away while he battered down the walls of Toulon. As soon as the Committee of Public Safety heard of the victory Napoleon became a brigadier general, the start of his meteoric rise to power. The Bonapartes were back in Ajaccio in 1797 under the protection of General Napoleon. Soon after Napoleon became First Consul and then emperor, using his office to spread revolution throughout Europe. In 1811 he made Ajaccio the capital of the new Department of Corsica. Despite his subsequent defeat by the Prussians, Russians, and British, his exile and his death, no victorious power reversed that decision or tried to remove Corsica from France. Among the natives, though Corsican nationalism is strong, and feeling often runs high in favour of a union with Italy; loyalty to France, however, as evidenced by elections, remains stronger. 19th and 20th centuries In the 19th century Ajaccio became a winter resort of the high society of the time, especially for the English, in the same way as Monaco, Cannes, and Nice. An Anglican Church was even built. The first prison in France for children was built in Ajaccio in 1855: the Horticultural colony of Saint Anthony. It was a correctional colony for juvenile delinquents (from 8 to 20 years old), established under Article 10 of the Act of 5 August 1850. Nearly 1,200 children from all over France stayed there until 1866, when it was closed. Sixty percent of them perished, the victims of poor sanitation and malaria which infested the unhealthy areas that they were responsible to clean. Contemporary history On 9 September 1943, the people of Ajaccio rose up against the Nazi occupiers and became the first French town to be liberated from the domination of the Germans. General Charles de Gaulle went to Ajaccio on 8 October 1943 and said: "We owe it to the field of battle the lesson of the page of history that was written in French Corsica. Corsica to her fortune and honour is the first morsel of France to be liberated; which was done intentionally and willingly, in the light of its liberation, this demonstrates that these are the intentions and the will of the whole nation." Throughout this period, no Jew was executed or deported from Corsica through the protection afforded by its people and its government. This event now allows Corsica to aspire to the title "Righteous Among the Nations", as no French region except for the commune Le Chambon-sur-Lignon in Haute-Loire carries this title. Their case is being investigated . Since the middle of the 20th century, Ajaccio has seen significant development. The city has seen population growth and considerable urban sprawl. Today Ajaccio is the capital of Corsica and the main town of the island and seeks to establish itself as a true regional centre. Ajaccio was a hotspot for violence during the violent unrest in March 2022. Economy The city is, with Bastia, the economic, commercial and administrative centre of Corsica. Its urban area of nearly 90,000 inhabitants is spread over a large part of the Corse-du-Sud, on either side of the Gulf of Ajaccio and up the valley of the Gravona. Its business is primarily oriented towards the services sector. The services sector is by far the main source of employment in the city. Ajaccio is an administrative centre comprising communal, intercommunal, departmental, regional, and prefectural services. It is also a shopping centre with the commercial streets of the city centre and the areas of peripheral activities such as that of Mezzavia (hypermarket Géant Casino) and along the ring road (hypermarket Carrefour and E. Leclerc). Tourism is one of the most vital aspects of the economy, split between the seaside tourism of summer, cultural tourism, and fishing. A number of hotels, varying from one star to five star, are present across the commune. Ajaccio is the seat of the Chamber of Commerce and Industry of Ajaccio and Corsica South. It manages the ports of Ajaccio, Bonifacio, Porto-Vecchio, Propriano and the Tino Rossi marina. It also manages Ajaccio airport and Figari airport as well as the convention centre and the Centre of Ricanto. Secondary industry is underdeveloped, apart from the aeronautical company Corsica Aerospace Composites CCA, the largest company on the island with 135 employees at two sites. The storage sites of GDF Suez (formerly Gaz de France) and Antargaz in the district of Vazzio are classified as high risk. Energy The Centrale EDF du Vazzio, a heavy oil power station, provides the south of the island with electricity. The Gravona Canal delivers water for consumption by the city. Transport Road access By road, the city is accessible from National Route NR194 from Bastia and NR193 via NR196 from Bonifacio. These two main axes, as well as the roads leading to suburban villages, connect Ajaccio from the north - the site of Ajaccio forming a dead end blocked by the sea to the south. Only the Cours Napoleon and the Boulevard du Roi Jerome cross the city. Along with the high urban density, this explains the major traffic and parking problems especially during peak hours and during the summer tourist season. A bypass through several neighbourhoods is nearing completion. Communal bus services The Muvistrada provide services on 21 urban routes, one "city" route for local links and 20 suburban lines. The frequency varies according to demand with intervals of 30 minutes for the most important routes: A park and ride with 300 spaces was built at Mezzana in the neighbouring commune of Sarrola-Carcopino in order to promote intermodality between cars and public transport. It was inaugurated on 12 July 2010. Airport The city is served by an Ajaccio Napoleon Bonaparte Airport which is the headquarters of Air Corsica, a Corsican airline. It connects Ajaccio to a number of cities in mainland France (including Paris, Marseille, Nice, and Brive) and to places in Europe to serve the tourist industry. The airline CCM Airlines also has its head office on the grounds of the Airport. Port The port of Ajaccio is connected to the French mainland on an almost daily basis (Marseille, Toulon, Nice). There are also occasional links to the Italian mainland (Livorno) and to Sardinia, as well as a seasonal service serving Calvi and Propriano. The two major shipping companies providing these links are Corsica Linea and Corsica Ferries. Ajaccio has also become a stopover for cruises with a total of 418,086 passengers in 2007by far the largest in Corsica and the second-largest in France (after Marseille, but ahead of Nice/Villefranche-sur-Mer and Cannes). The goal is for Ajaccio to eventually become the premier French port for cruises as well as being a main departure point. The Port function of the city is also served by the commercial, pleasure craft, and artisanal fisheries (3 ports). Railways The railway station in Ajaccio belongs to Chemins de fer de la Corse and is located near the port at the Square Pierre Griffi. It connects Ajaccio to Corte, Bastia (3 h 25 min) and Calvi. There are two optional stops: Salines Halt north of the city in the district of the same name Campo dell'Oro Halt near the airport In addition, the municipality has introduced an additional commuter service between Mezzana station in the suburbs and Ajaccio station located in the centre. Administration Ajaccio was successively: Capital of the district of the department of Corsica in 1790 to 1793 Capital of the department of Liamone from 1793 to 1811 Capital of the department of Corsica from 1811 to 1975 Capital of the region and the collectivité territoriale de Corse since 1970 and the department of Corse-du-Sud since 1976 Policy Ajaccio remained (with some interruptions) an electoral stronghold of the Bonapartist (CCB) party until the municipal elections of 2001. The outgoing municipality was then beaten by a left-wing coalition led by Simon Renucci which gathered Social Democrats, Communists, and Charles Napoleon - the pretender to the imperial throne. List of Successive Mayors of Ajaccio Quarters 10 Quarters are recognized by the municipality. Cannes-Binda: an area north of the city, consisting of Housing estates, classed as a Sensitive urban zone (ZUS) with Les Salines, subject to a policy of urban renewal Centre Ville: The tourist heart of the city consisting of shopping streets and major thoroughfares Casone: a bourgeois neighbourhood with an affluent population located in the former winter resort on the heights of the southern city. Les Jardins de l'Empereur: a neighbourhood classified as a Sensitive urban zone (ZUS) on the heights of the city, consisting of housing estates overlooking the city Mezzavia: northern quarter of the town with several subdivisions and areas of business and economic activities Octroi-Sainte Lucie: constitutes the northern part of the city centre near the port and the railway station Pietralba: quarter northeast of the city, classified ZUS Résidence des Îles: quarter to the south of the city near the tourist route of Sanguinaires in a quality environment Saint-Jean: collection of buildings for a population with low incomes, close to the historic urban core of the city, classified as a Sensitive urban zone (ZUS) Saline: quarter north of the city, consisting of large apartment blocks, classed as a Sensitive urban zone (ZUS) with Les Cannes, subject to a policy of urban renewal Vazzio: quarter northeast of the city, near the airport, the EDF Central, and the Francois Coty stadium. Intercommunality Since December 2001, Ajaccio has been part of the Communauté d'agglomération du Pays Ajaccien with nine other communes: Afa, Alata, Appietto, Cuttoli-Corticchiato, Peri, Sarrola-Carcopino, Tavaco, Valle-di-Mezzana, and Villanova. Origins The geopolitical arrangements of the commune are slightly different from those typical of Corsica and France. Usually an arrondissement includes cantons and a canton includes one to several communes including the chef-lieu, "chief place", from which the canton takes its name. The city of Ajaccio is one commune, but it contains four cantons, Cantons 1–4, and a fraction of Canton 5. The latter contains three other communes: Bastelicaccia, Alata and Villanova, making a total of four communes for the five cantons of Ajaccio. Each canton contains a certain number of quartiers, "quarters". Cantons 1, 2, 3, 4 are located along the Gulf of Ajaccio from west to east, while 5 is a little further up the valleys of the Gravona and the Prunelli Rivers. These political divisions subdivide the population of Ajaccio into units that can be more democratically served but they do not give a true picture of the size of Ajaccio. In general language, "greater Ajaccio" includes about 100,000 people with all the medical, educational, utility and transportational facilities of a big city. Up until World War II it was still possible to regard the city as being a settlement of narrow streets localized to a part of the harbour or the Gulf of Ajaccio: such bucolic descriptions do not fit the city of today, and travelogues intended for mountain or coastal recreational areas do not generally apply to Corsica's few big cities. The arrondissement contains other cantons that extend generally up the two rivers into central Corsica. Twin towns – sister cities Ajaccio is twinned with: La Maddalena, Italy (1991) Population The population of Ajaccio increased sharply after 1960 due to migration from rural areas and the coming of "Pied-Noirs" (French Algerians), immigrants from the Maghreb and French from mainland France. Health Ajaccio has three hospital sites: the Misericordia Hospital, built in 1950, is located on the heights of the city centre. This is the main medical facility in the region. The Annex Eugenie. the Psychiatric Hospital of Castelluccio is west of the city centre and is also home of cancer services and long-stay patients. Education Ajaccio is the headquarters of the Academy of Corsica. The city of Ajaccio has: 18 nursery schools (16 public and 2 private) 17 primary schools (15 public and 2 private) 6 colleges 5 Public Schools: Collège Arthur-Giovoni Collège des Padule Collège Laetitia Bonaparte Collège Fesch EREA 1 Private School: Institution Saint Paul 3 sixth-form colleges/senior high schools 2 public schools: Lycée Laetitia Bonaparte Lycée Fesch 1 private: Institution Saint Paul 2 LEP (vocational high schools) Lycée Finosello Lycée Jules Antonini Higher education is undeveloped except for a few BTS and IFSI, the University of Corsica Pascal Paoli is located in Corte. A research facility of INRA is also located on Ajaccio. Culture and heritage Ajaccio has a varied tourism potential, with both a cultural framework in the centre of the city and a natural heritage around the coves and beaches of the Mediterranean Sea, as well as the Natura 2000 reserve of the îles Sanguinaires. Civil heritage The commune has many buildings and structures that are registered as historical monuments: The Monument to General Abbatucci in the Place Abbatucci (1854) The Monument to Napoleon I in the Place d'Austerlitz (20th century) The Baciocchi Family Mansion at 9 Rue Bonaparte (18th century) The Fesch Palace at 48 bis Rue Cardinal-Fesch (1827) The Monument to the First Consul in the Place Foch (1850) The Peraldi House at 18 Rue Forcioli-Conti (1820) The Grand Hotel at Cours Grandval (1869) The old Château Conti at Cours Grandval (19th century) The Monument to Napoleon and his brothers in the Place du General de Gaulle (1864) The Monument to Cardinal Fesch at the Cour du Musée Fesch (1856) The old Alban Factory at 89 Cours Napoleon (1913) The Milelli House in the Saint-Antoine Quarter (17th century) The Hotel Palace-Cyrnos (1880), an old Luxury Hotel from the 19th century and a famous palace of the old days in the quarter "for foreigners" now converted into housing.

Other religious sites of interest The Church of Saint Roch, Neoclassical architecture by Ajaccien project architect Barthélémy Maglioli (1885) Environmental heritage Sanguinaires Archipelago: The Route des Sanguinaires runs along the southern coast of the city after the Saint François Beach. It is lined with villas and coves and beaches. Along the road is the Ajaccio cemetery with the grave of Corsican singer Tino Rossi. At the mouth of the Route des Sanguinaires is the Pointe de la Parata near the archipelago and the lighthouse. The Sentier des Crêtes (Crest Trail) starts from the city centre and is an easy hike offering splendid views of the Gulf of Ajaccio. The shores of the Gulf are dotted with a multitude of small coves and beaches ideal for swimming and scuba diving. Many small paths traversing the maquis (high ground covered in thick vegetation) in the commune from which the Maquis resistance network was named. Interests The city has two marinas and a casino.

The Ajanta Caves are 29 rock-cut Buddhist cave monuments dating from the second century BCE to about 480 CE in the Aurangabad District of Maharashtra state in India. Ajanta Caves are a UNESCO World Heritage Site. Universally regarded as masterpieces of Buddhist religious art, the caves include paintings and rock-cut sculptures described as among the finest surviving examples of ancient Indian art, particularly expressive paintings that present emotions through gesture, pose and form. The caves were built in two phases, the first starting around the second century BCE and the second occurring from 400 to 650 CE, according to older accounts, or in a brief period of 460–480 CE according to later scholarship. The Ajanta Caves constitute ancient monasteries (Viharas) and worship-halls (Chaityas) of different Buddhist traditions carved into a wall of rock. The caves also present paintings depicting the past lives and rebirths of the Buddha, pictorial tales from Aryasura's Jatakamala, and rock-cut sculptures of Buddhist deities. Textual records suggest that these caves served as a monsoon retreat for monks, as well as a resting site for merchants and pilgrims in ancient India. While vivid colours and mural wall paintings were abundant in Indian history as evidenced by historical records, Caves 1, 2, 16 and 17 of Ajanta form the largest corpus of surviving ancient Indian wall-paintings. The Ajanta Caves are mentioned in the memoirs of several medieval-era Chinese Buddhist travellers. They were covered by jungle until accidentally "discovered" and brought to Western attention in 1819 by a colonial British officer Captain John Smith on a tiger-hunting party. The caves are in the rocky northern wall of the U-shaped gorge of the river Waghur, in the Deccan plateau. Within the gorge are a number of waterfalls, audible from outside the caves when the river is high. With the Ellora Caves, Ajanta is one of the major tourist attractions of Maharashtra. It is about from the city of Jalgaon, Maharashtra, India, from the city of Aurangabad, and east-northeast of Mumbai. Ajanta is from the Ellora Caves, which contain Hindu, Jain and Buddhist caves, the last dating from a period similar to Ajanta. The Ajanta style is also found in the Ellora Caves and other sites such as the Elephanta Caves, Aurangabad Caves, Shivleni Caves and the cave temples of Karnataka. History The Ajanta Caves are generally agreed to have been made in two distinct phases; first during the 2nd century BCE to 1st century CE, and second several centuries later. The caves consist of 36 identifiable foundations, some of them discovered after the original numbering of the caves from 1 through 29. The later-identified caves have been suffixed with the letters of the alphabet, such as 15A, identified between originally numbered caves 15 and 16. The cave numbering is a convention of convenience, and does not reflect the chronological order of their construction. Caves of the first (Satavahana) period The earliest group consists of caves 9, 10, 12, 13 and 15A. The murals in these caves depict stories from the Jatakas. Later caves reflect the artistic influence of the Gupta period, but there are differing opinions on which century in which the early caves were built. According to Walter Spink, they were made during the period 100 BCE to 100 CE, probably under the patronage of the Hindu Satavahana dynasty (230 BCE – c. 220 CE) who ruled the region. Other datings prefer the period of the Maurya Empire (300 BCE to 100 BCE). Of these, caves 9 and 10 are stupa containing worship halls of chaitya-griha form, and caves 12, 13, and 15A are vihāras (see the architecture section below for descriptions of these types). The first Satavahana period caves lacked figurative sculpture, emphasizing the stupa instead. According to Spink, once the Satavahana period caves were made, the site was not further developed for a considerable period until the mid-5th century. However, the early caves were in use during this dormant period, and Buddhist pilgrims visited the site, according to the records left by Chinese pilgrim Faxian around 400 CE. Caves of the later or Vākāṭaka period The second phase of construction at the Ajanta Caves site began in the 5th century. For a long time it was thought that the later caves were made over an extended period from the 4th to the 7th centuries CE, but in recent decades a series of studies by the leading expert on the caves, Walter M. Spink, have argued that most of the work took place over the very brief period from 460 to 480 CE, during the reign of Hindu Emperor Harishena of the Vākāṭaka dynasty. This view has been criticised by some scholars, but is now broadly accepted by most authors of general books on Indian art, for example, Huntington and Harle. The second phase is attributed to the theistic Mahāyāna, or Greater Vehicle tradition of Buddhism. Caves of the second period are 1–8, 11, 14–29, some possibly extensions of earlier caves. Caves 19, 26, and 29 are chaitya-grihas, the rest viharas. The most elaborate caves were produced in this period, which included some refurbishing and repainting of the early caves. Spink states that it is possible to establish dating for this period with a very high level of precision; a fuller account of his chronology is given below. Although debate continues, Spink's ideas are increasingly widely accepted, at least in their broad conclusions. The Archaeological Survey of India website still presents the traditional dating: "The second phase of paintings started around 5th–6th centuries A.D. and continued for the next two centuries". According to Spink, the construction activity at the incomplete Ajanta Caves was abandoned by wealthy patrons in about 480 CE, a few years after the death of Harishena. However, states Spink, the caves appear to have been in use for a period of time as evidenced by the wear of the pivot holes in caves constructed close to 480 CE. The second phase of constructions and decorations at Ajanta corresponds to the very apogee of Classical India, or India's golden age. However, at that time, the Gupta Empire was already weakening from internal political issues and from the assaults of the Hūṇas, so that the Vakatakas were actually one of the most powerful empires in India. Some of the Hūṇas, the Alchon Huns of Toramana, were precisely ruling the neighbouring area of Malwa, at the doorstep of the Western Deccan, at the time the Ajanta caves were made. Through their control of vast areas of northwestern India, the Huns may actually have acted as a cultural bridge between the area of Gandhara and the Western Deccan, at the time when the Ajanta or Pitalkhora caves were being decorated with some designs of Gandharan inspiration, such as Buddhas dressed in robes with abundant folds. According to Richard Cohen, a description of the caves by 7th-century Chinese traveler Xuanzang and scattered medieval graffiti suggest that the Ajanta Caves were known and probably in use subsequently, but without a stable or steady Buddhist community presence. The Ajanta caves are mentioned in the 17th-century text Ain-i-Akbari by Abu al-Fazl, as twenty four rock-cut cave temples each with remarkable idols. Colonial era On 28 April 1819 a British officer named John Smith, of the 28th Cavalry, while hunting tigers was shown the entrance to Cave No. 10 when a local shepherd boy guided him to the location and the door. The caves were well known by locals already. Captain Smith went to a nearby village and asked the villagers to come to the site with axes, spears, torches, and drums, to cut down the tangled jungle growth that made entering the cave difficult. He then deliberately damaged an image on the wall by scratching his name and the date over the painting of a bodhisattva. Since he stood on a five-foot high pile of rubble collected over the years, the inscription is well above the eye-level gaze of an adult today. A paper on the caves by William Erskine was read to the Bombay Literary Society in 1822. Within a few decades, the caves became famous for their exotic setting, impressive architecture, and above all their exceptional and unique paintings. A number of large projects to copy the paintings were made in the century after rediscovery. In 1848, the Royal Asiatic Society established the "Bombay Cave Temple Commission" to clear, tidy and record the most important rock-cut sites in the Bombay Presidency, with John Wilson as president. In 1861 this became the nucleus of the new Archaeological Survey of India. During the colonial era, the Ajanta site was in the territory of the princely state of the Hyderabad and not British India. In the early 1920s, Mir Osman Ali Khan the last Nizam of Hyderabad appointed people to restore the artwork, converted the site into a museum and built a road to bring tourists to the site for a fee. These efforts resulted in early mismanagement, states Richard Cohen, and hastened the deterioration of the site. Post-independence, the state government of Maharashtra built arrival, transport, facilities, and better site management. The modern Visitor Center has good parking facilities and public conveniences and ASI operated buses run at regular intervals from Visitor Center to the caves. The Nizam's Director of Archaeology obtained the services of two experts from Italy, Professor Lorenzo Cecconi, assisted by Count Orsini, to restore the paintings in the caves. The Director of Archaeology for the last Nizam of Hyderabad said of the work of Cecconi and Orsini: Despite these efforts, later neglect led to the paintings degrading in quality once again. Since 1983, Ajanta caves have been listed among the UNESCO World Heritage Sites of India. The Ajanta Caves, along with the Ellora Caves, have become the most popular tourist destination in Maharashtra, and are often crowded at holiday times, increasing the threat to the caves, especially the paintings. In 2012, the Maharashtra Tourism Development Corporation announced plans to add to the ASI visitor centre at the entrance complete replicas of caves 1, 2, 16 & 17 to reduce crowding in the originals, and enable visitors to receive a better visual idea of the paintings, which are dimly-lit and hard to read in the caves. Sites and monasteries Sites The caves are carved out of flood basalt and granite rock of a cliff, part of the Deccan Traps formed by successive volcanic eruptions at the end of the Cretaceous geological period. The rock is layered horizontally, and somewhat variable in quality. This variation within the rock layers required the artists to amend their carving methods and plans in places. The inhomogeneity in the rock has also led to cracks and collapses in the centuries that followed, as with the lost portico to cave 1. Excavation began by cutting a narrow tunnel at roof level, which was expanded downwards and outwards; as evidenced by some of the incomplete caves such as the partially-built vihara caves 21 through 24 and the abandoned incomplete cave 28. The sculpture artists likely worked at both excavating the rocks and making the intricate carvings of pillars, roof, and idols; further, the sculpture and painting work inside a cave were integrated parallel tasks. A grand gateway to the site was carved, at the apex of the gorge's horseshoe between caves 15 and 16, as approached from the river, and it is decorated with elephants on either side and a nāga, or protective Naga (snake) deity. Similar methods and application of artist talent is observed in other cave temples of India, such as those from Hinduism and Jainism. These include the Ellora Caves, Ghototkacha Caves, Elephanta Caves, Bagh Caves, Badami Caves, Aurangabad Caves and Shivleni Caves. The caves from the first period seem to have been paid for by a number of different patrons to gain merit, with several inscriptions recording the donation of particular portions of a single cave. The later caves were each commissioned as a complete unit by a single patron from the local rulers or their court elites, again for merit in Buddhist afterlife beliefs as evidenced by inscriptions such as those in Cave 17. After the death of Harisena, smaller donors motivated by getting merit added small "shrinelets" between the caves or add statues to existing caves, and some two hundred of these "intrusive" additions were made in sculpture, with a further number of intrusive paintings, up to three hundred in cave 10 alone. Monasteries The majority of the caves are vihara halls with symmetrical square plans. To each vihara hall are attached smaller square dormitory cells cut into the walls. A vast majority of the caves were carved in the second period, wherein a shrine or sanctuary is appended at the rear of the cave, centred on a large statue of the Buddha, along with exuberantly detailed reliefs and deities near him as well as on the pillars and walls, all carved out of the natural rock. This change reflects the shift from Hinayana to Mahāyāna Buddhism. These caves are often called monasteries. The central square space of the interior of the viharas is defined by square columns forming a more-or-less square open area. Outside this are long rectangular aisles on each side, forming a kind of cloister. Along the side and rear walls are a number of small cells entered by a narrow doorway; these are roughly square, and have small niches on their back walls. Originally they had wooden doors. The centre of the rear wall has a larger shrine-room behind, containing a large Buddha statue. The viharas of the earlier period are much simpler, and lack shrines. Spink places the change to a design with a shrine to the middle of the second period, with many caves being adapted to add a shrine in mid-excavation, or after the original phase. The plan of Cave 1 shows one of the largest viharas, but is fairly typical of the later group. Many others, such as Cave 16, lack the vestibule to the shrine, which leads straight off the main hall. Cave 6 is two viharas, one above the other, connected by internal stairs, with sanctuaries on both levels. Worship halls The other type of main hall architecture is the narrower rectangular plan with high arched ceiling type chaitya-griha – literally, "the house of stupa". This hall is longitudinally divided into a nave and two narrower side aisles separated by a symmetrical row of pillars, with a stupa in the apse. The stupa is surrounded by pillars and concentric walking space for circumambulation. Some of the caves have elaborate carved entrances, some with large windows over the door to admit light. There is often a colonnaded porch or verandah, with another space inside the doors running the width of the cave. The oldest worship halls at Ajanta were built in the 2nd to 1st century BCE, the newest ones in the late 5th century CE, and the architecture of both resembles the architecture of a Christian church, but without the crossing or chapel chevette. The Ajanta Caves follow the Cathedral-style architecture found in still older rock-cut cave carvings of ancient India, such as the Lomas Rishi Cave of the Ajivikas near Gaya in Bihar dated to the 3rd century BCE. These chaitya-griha are called worship or prayer halls. The four completed chaitya halls are caves 9 and 10 from the early period, and caves 19 and 26 from the later period of construction. All follow the typical form found elsewhere, with high ceilings and a central "nave" leading to the stupa, which is near the back, but allows walking behind it, as walking around stupas was (and remains) a common element of Buddhist worship (pradakshina). The later two have high ribbed roofs carved into the rock, which reflect timber forms, and the earlier two are thought to have used actual timber ribs and are now smooth, the original wood presumed to have perished. The two later halls have a rather unusual arrangement (also found in Cave 10 at Ellora) where the stupa is fronted by a large relief sculpture of the Buddha, standing in Cave 19 and seated in Cave 26. Cave 29 is a late and very incomplete chaitya hall. The form of columns in the work of the first period is very plain and un-embellished, with both chaitya halls using simple octagonal columns, which were later painted with images of the Buddha, people and monks in robes. In the second period columns were far more varied and inventive, often changing profile over their height, and with elaborate carved capitals, often spreading wide. Many columns are carved over all their surface with floral motifs and Mahayana deities, some fluted and others carved with decoration all over, as in cave 1. Paintings Most of the Ajanta caves, and almost all the murals paintings date from nearly 600 years later, during a second phase of construction. The paintings in the Ajanta caves predominantly narrate the Jataka tales. These are Buddhist legends describing the previous births of the Buddha. These fables embed ancient morals and cultural lores that are also found in the fables and legends of Hindu and Jain texts. The Jataka tales are exemplified through the life example and sacrifices that the Buddha made in hundreds of his past incarnations, where he is depicted as having been reborn as an animal or human. Mural paintings survive from both the earlier and later groups of caves. Several fragments of murals preserved from the earlier caves (Caves 10 and 11) are effectively unique survivals of ancient painting in India from this period, and "show that by Sātavāhana times, if not earlier, the Indian painters had mastered an easy and fluent naturalistic style, dealing with large groups of people in a manner comparable to the reliefs of the Sāñcī toraņa crossbars". Some connections with the art of Gandhara can also be noted, and there is evidence of a shared artistic idiom. Four of the later caves have large and relatively well-preserved mural paintings which, states James Harle, "have come to represent Indian mural painting to the non-specialist", and represent "the great glories not only of Gupta but of all Indian art". They fall into two stylistic groups, with the most famous in Caves 16 and 17, and apparently later paintings in Caves 1 and 2. The latter group were thought to be a century or later than the others, but the revised chronology proposed by Spink would place them in the 5th century as well, perhaps contemporary with it in a more progressive style, or one reflecting a team from a different region. The Ajanta frescos are classical paintings and the work of confident artists, without cliches, rich and full. They are luxurious, sensuous and celebrate physical beauty, aspects that early Western observers felt were shockingly out of place in these caves presumed to be meant for religious worship and ascetic monastic life. The paintings are in "dry fresco", painted on top of a dry plaster surface rather than into wet plaster. All the paintings appear to be the work of painters supported by discriminating connoisseurship and sophisticated patrons from an urban atmosphere. We know from literary sources that painting was widely practised and appreciated in the Gupta period. Unlike much Indian mural painting, compositions are not laid out in horizontal bands like a frieze, but show large scenes spreading in all directions from a single figure or group at the centre. The ceilings are also painted with sophisticated and elaborate decorative motifs, many derived from sculpture. The paintings in cave 1, which according to Spink was commissioned by Harisena himself, concentrate on those Jataka tales which show previous lives of the Buddha as a king, rather than as deer or elephant or another Jataka animal. The scenes depict the Buddha as about to renounce the royal life. In general the later caves seem to have been painted on finished areas as excavating work continued elsewhere in the cave, as shown in caves 2 and 16 in particular. According to Spink's account of the chronology of the caves, the abandonment of work in 478 after a brief busy period accounts for the absence of painting in places including cave 4 and the shrine of cave 17, the later being plastered in preparation for paintings that were never done. Spink's chronology and cave history Walter Spink has over recent decades developed a very precise and circumstantial chronology for the second period of work on the site, which unlike earlier scholars, he places entirely in the 5th century. This is based on evidence such as the inscriptions and artistic style, dating of nearby cave temple sites, comparative chronology of the dynasties, combined with the many uncompleted elements of the caves. He believes the earlier group of caves, which like other scholars he dates only approximately, to the period "between 100 BCE – 100 CE", were at some later point completely abandoned and remained so "for over three centuries". This changed during the Hindu emperor Harishena of the Vakataka Dynasty, who reigned from 460 to his death in 477, who sponsored numerous new caves during his reign. Harisena's rule extended the Central Indian Vakataka Empire to include a stretch of the east coast of India; the Gupta Empire ruled northern India at the same period, and the Pallava dynasty much of the south. According to Spink, Harisena encouraged a group of associates, including his prime minister Varahadeva and Upendragupta, the sub-king in whose territory Ajanta was, to dig out new caves, which were individually commissioned, some containing inscriptions recording the donation. This activity began in many caves simultaneously about 462. This activity was mostly suspended in 468 because of threats from the neighbouring Asmaka kings. Thereafter work continued on only Caves 1, Harisena's own commission, and 17–20, commissioned by Upendragupta. In 472 the situation was such that work was suspended completely, in a period that Spink calls "the Hiatus", which lasted until about 475, by which time the Asmakas had replaced Upendragupta as the local rulers. Work was then resumed, but again disrupted by Harisena's death in 477, soon after which major excavation ceased, except at cave 26, which the Asmakas were sponsoring themselves. The Asmakas launched a revolt against Harisena's son, which brought about the end of the Vakataka Dynasty. In the years 478–480 CE major excavation by important patrons was replaced by a rash of "intrusions" – statues added to existing caves, and small shrines dotted about where there was space between them. These were commissioned by less powerful individuals, some monks, who had not previously been able to make additions to the large excavations of the rulers and courtiers. They were added to the facades, the return sides of the entrances, and to walls inside the caves. According to Spink, "After 480, not a single image was ever made again at the site". However, there exists a Rashtrakuta inscription outside of cave 26 dateable to end of seventh or early 8th century, suggesting the caves were not abandoned until then. Spink does not use "circa" in his dates, but says that "one should allow a margin of error of one year or perhaps even two in all cases". Hindu and Buddhist sponsorship The Ajanta Caves were built in a period when both the Buddha and the Hindu gods were simultaneously revered in Indian culture. According to Spink and other scholars, the royal Vakataka sponsors of the Ajanta Caves probably worshipped both Hindu and Buddhist gods. This is evidenced by inscriptions in which these rulers, who are otherwise known as Hindu devotees, made Buddhist dedications to the caves. According to Spink, A terracotta plaque of Mahishasuramardini, also known as Durga, was also found in a burnt-brick vihara monastery facing the caves on the right bank of the river Waghora that has been recently excavated. This suggest that the deity was possibly under worship by the artisans. According to Yuko Yokoschi and Walter Spink, the excavated artifacts of the 5th century near the site suggest that the Ajanta caves deployed a huge number of builders. Cave 1 Cave 1 was built on the eastern end of the horseshoe-shaped scarp and is now the first cave the visitor encounters. This cave, when first made, would have been in a less prominent position, right at the end of the row. According to Spink, it is one of the last caves to have been excavated, when the best sites had been taken, and was never fully inaugurated for worship by the dedication of the Buddha image in the central shrine. This is shown by the absence of sooty deposits from butter lamps on the base of the shrine image, and the lack of damage to the paintings that would have happened if the garland-hooks around the shrine had been in use for any period of time. Spink states that the Vākāṭaka Emperor Harishena was the benefactor of the work, and this is reflected in the emphasis on imagery of royalty in the cave, with those Jataka tales being selected that tell of those previous lives of the Buddha in which he was royal. The cliff has a steeper slope here than at other caves, so to achieve a tall grand facade it was necessary to cut far back into the slope, giving a large courtyard in front of the facade. There was originally a columned portico in front of the present facade, which can be seen "half-intact in the 1880s" in pictures of the site, but this fell down completely and the remains, despite containing fine carvings, were carelessly thrown down the slope into the river and lost. This cave (35.7 m × 27.6 m) has one of the most elaborate carved facades, with relief sculptures on entablature and ridges, and most surfaces embellished with decorative carving. There are scenes carved from the life of the Buddha as well as a number of decorative motifs. A two-pillared portico, visible in the 19th-century photographs, has since perished. The cave has a forecourt with cells fronted by pillared vestibules on either side. These have a high plinth level. The cave has a porch with simple cells at both ends. The absence of pillared vestibules on the ends suggests that the porch was not excavated in the latest phase of Ajanta when pillared vestibules had become customary. Most areas of the porch were once covered with murals, of which many fragments remain, especially on the ceiling. There are three doorways: a central doorway and two side doorways. Two square windows were carved between the doorways to brighten the interiors. Each wall of the hall inside is nearly long and high. Twelve pillars make a square colonnade inside, supporting the ceiling and creating spacious aisles along the walls. There is a shrine carved on the rear wall to house an impressive seated image of the Buddha, his hands being in the dharmachakrapravartana mudra. There are four cells on each of the left, rear, and the right walls, though due to rock fault there are none at the ends of the rear aisle. The paintings of Cave 1 cover the walls and the ceilings. They are in a fair state of preservation, although the full scheme was never completed. The scenes depicted are mostly didactic, devotional, and ornamental, with scenes from the chalukya corutstories about Persian ambassador in pulikeshin 2nd corut tells the relationship btw chalukya empire and Persian Empire Jataka stories of the Buddha's former lives as a bodhisattva, the life of the Gautama Buddha, and those of his veneration. The two most famous individual painted images at Ajanta are the two over-lifesize figures of the protective bodhisattvas Padmapani and Vajrapani on either side of the entrance to the Buddha shrine on the wall of the rear aisle (see illustrations above). Other significant frescoes in Cave 1 include the Sibi, Sankhapala, Mahajanaka, Mahaummagga, and Champeyya Jataka tales. The cave-paintings also show the Temptation of Mara, the miracle of Sravasti where the Buddha simultaneously manifests in many forms, the story of Nanda, and the story of Siddhartha and Yasodhara. Cave 2 Cave 2, adjacent to Cave 1, is known for the paintings that have been preserved on its walls, ceilings, and pillars. It looks similar to Cave 1 and is in a better state of preservation. This cave is best known for its feminine focus, intricate rock carvings and paint artwork yet it is incomplete and lacks consistency. One of the 5th-century frescos in this cave also shows children at a school, with those in the front rows paying attention to the teacher, while those in the back row are shown distracted and acting. Cave 2 (35.7 m × 21.6 m) was started in the 460s, but mostly carved between 475 and 477 CE, probably sponsored and influenced by a woman closely related to emperor Harisena. It has a porch quite different from Cave 1. Even the façade carvings seem to be different. The cave is supported by robust pillars, ornamented with designs. The front porch consists of cells supported by pillared vestibules on both ends. The hall has four colonnades which are supporting the ceiling and surrounding a square in the center of the hall. Each arm or colonnade of the square is parallel to the respective walls of the hall, making an aisle in between. The colonnades have rock-beams above and below them. The capitals are carved and painted with various decorative themes that include ornamental, human, animal, vegetative, and semi-divine motifs. Major carvings include that of goddess Hariti. She is a Buddhist deity who originally was the demoness of smallpox and a child eater, who the Buddha converted into a guardian goddess of fertility, easy child birth and one who protects babies. The paintings on the ceilings and walls of Cave 2 have been widely published. They depict the Hamsa, Vidhurapandita, Ruru, Kshanti Jataka tales and the Purna Avadhana. Other frescos show the miracle of Sravasti, Ashtabhaya Avalokitesvara and the dream of Maya. Just as the stories illustrated in cave 1 emphasise kingship, those in cave 2 show many noble and powerful women in prominent roles, leading to suggestions that the patron was an unknown woman. The porch's rear wall has a doorway in the center, which allows entrance to the hall. On either side of the door is a square-shaped window to brighten the interior. Cave 3 Cave 3 is merely a start of an excavation; according to Spink it was begun right at the end of the final period of work and soon abandoned. This is an incomplete monastery and only the preliminary excavations of pillared veranda exist. The cave was one of the last projects to start at the site. Its date could be ascribed to circa 477 CE, just before the sudden death of Emperor Harisena. The work stopped after the scooping out of a rough entrance of the hall. Cave 4 Cave 4, a Vihara, was sponsored by Mathura, likely not a noble or courtly official, rather a wealthy devotee. This is the largest vihara in the inaugural group, which suggests he had immense wealth and influence without being a state official. It is placed at a significantly higher level, possibly because the artists realized that the rock quality at the lower and same level of other caves was poor and they had a better chance of a major vihara at an upper location. Another likely possibility is that the planners wanted to carve into the rock another large cistern to the left courtside for more residents, mirroring the right, a plan implied by the height of the forward cells on the left side. The Archaeological Survey of India dates it to the 6th century CE. Spink, in contrast, dates this cave's inauguration a century earlier, to about 463 CE, based on construction style and other inscriptions. Cave 4 shows evidence of a dramatic collapse of its ceiling in the central hall, likely in the 6th century, something caused by the vastness of the cave and geological flaws in the rock. Later, the artists attempted to overcome this geological flaw by raising the height of the ceiling through deeper excavation of the embedded basalt lava. The cave has a squarish plan, houses a colossal image of the Buddha in preaching pose flanked by bodhisattvas and celestial nymphs hovering above. It consists, of a verandah, a hypostylar hall, sanctum with an antechamber and a series of unfinished cells. This monastery is the largest among the Ajanta caves and it measures nearly (35m × 28m). The door frame is exquisitely sculpted flanking to the right is carved Bodhisattva as reliever of Eight Great Perils. The rear wall of the verandah contains the panel of litany of Avalokiteśvara. The cave's ceiling collapse likely affected its overall plan, caused it being left incomplete. Only the Buddha's statue and the major sculptures were completed, and except for what the sponsor considered most important elements all other elements inside the cave were never painted. Cave 5 Cave 5, an unfinished excavation, was planned as a monastery (10.32 × 16.8 m). Cave 5 is devoid of sculpture and architectural elements except the door frame. The ornate carvings on the frame has female figures with mythical makara creatures found in ancient and medieval-era Indian arts. The cave's construction was likely initiated about 465 CE but abandoned because the rock has geological flaws. The construction was resumed in 475 CE after Asmakas restarted work at the Ajanta caves, but abandoned again as the artists and sponsor redesigned and focussed on an expanded Cave 6 that abuts Cave 5. Cave 6 Cave 6 is two-storey monastery (16.85 × 18.07 m). It consists of a sanctum, a hall on both levels. The lower level is pillared and has attached cells. The upper hall also has subsidiary cells. The sanctums on both level feature a Buddha in the teaching posture. Elsewhere, the Buddha is shown in different mudras. The lower level walls depict the Miracle of Sravasti and the Temptation of Mara legends. Only the lower floor of cave 6 was finished. The unfinished upper floor of cave 6 has many private votive sculptures, and a shrine Buddha. The lower level of Cave 6 likely was the earliest excavation in the second stage of construction. This stage marked the Mahayana theme and Vakataka renaissance period of Ajanta reconstruction that started about four centuries after the earlier Hinayana theme construction. The upper storey was not envisioned in the beginning, it was added as an afterthought, likely around the time when the architects and artists abandoned further work on the geologically-flawed rock of Cave 5 immediately next to it. Both lower and upper Cave 6 show crude experimentation and construction errors. The cave work was most likely in progress between 460 and 470 CE, and it is the first that shows attendant Bodhisattvas. The upper cave construction probably began in 465, progressed swiftly, and much deeper into the rock than the lower level. The walls and sanctum's door frame of the both levels are intricately carved. These show themes such as makaras and other mythical creatures, apsaras, elephants in different stages of activity, females in waving or welcoming gesture. The upper level of Cave 6 is significant in that it shows a devotee in a kneeling posture at the Buddha's feet, an indication of devotional worship practices by the 5th century. The colossal Buddha of the shrine has an elaborate throne back, but was hastily finished in 477/478 CE, when king Harisena died. The shrine antechamber of the cave features an unfinished sculptural group of the Six Buddhas of the Past, of which only five statues were carved. This idea may have been influenced from those in Bagh Caves of Madhya Pradesh. Cave 7 Cave 7 is also a monastery (15.55 × 31.25 m) but a single storey. It consists of a sanctum, a hall with octagonal pillars, and eight small rooms for monks. The sanctum Buddha is shown in preaching posture. There are many art panels narrating Buddhist themes, including those of the Buddha with Nagamuchalinda and Miracle of Sravasti. Cave 7 has a grand facade with two porticos. The veranda has eight pillars of two types. One has an octagonal base with amalaka and lotus capital. The other lacks a distinctly shaped base, features an octagonal shaft instead with a plain capital. The veranda opens into an antechamber. On the left side in this antechamber are seated or standing sculptures such as those of 25 carved seated Buddhas in various postures and facial expressions, while on the right side are 58 seated Buddha reliefs in different postures, all placed on lotus. These Buddhas and others on the inner walls of the antechamber are a sculptural depiction of the Miracle of Sravasti in Buddhist theology. The bottom row shows two Nagas (serpents with hoods) holding the blooming lotus stalk. The antechamber leads to the sanctum through a door frame. On this frame are carved two females standing on makaras (mythical sea creatures). Inside the sanctum is the Buddha sitting on a lion throne in cross legged posture, surrounded by other Bodhisattva figures, two attendants with chauris and flying apsaras above. Perhaps because of faults in the rock, Cave 7 was never taken very deep into the cliff. It consists only of the two porticos and a shrine room with antechamber, with no central hall. Some cells were fitted in. The cave artwork likely underwent revisions and refurbishments over time. The first version was complete by about 469 CE, the myriad Buddhas added and painted a few years later between 476 and 478 CE. Cave 8 Cave 8 is another unfinished monastery (15.24 × 24.64 m). For many decades in the 20th-century, this cave was used as a storage and generator room. It is at the river level with easy access, relatively lower than other caves, and according to Archaeological Survey of India it is possibly one of the earliest monasteries. Much of its front is damaged, likely from a landslide. The cave excavation proved difficult and probably abandoned after a geological fault consisting of a mineral layer proved disruptive to stable carvings. Spink, in contrast, states that Cave 8 is perhaps the earliest cave from the second period, its shrine an "afterthought". It may well be the oldest Mahayana monastery excavated in India, according to Spink. The statue may have been loose rather than carved from the living rock, as it has now vanished. The cave was painted, but only traces remain. Cave 9 Caves 9 and 10 are the two chaitya or worship halls from the 2nd to 1st century BCE – the first period of construction, though both were reworked upon the end of the second period of construction in the 5th century CE. Cave 9 (18.24 m × 8.04 m) is smaller than Cave 10 (30.5 m × 12.2 m), but more complex. This has led Spink to the view that Cave 10 was perhaps originally of the 1st century BCE, and cave 9 about a hundred years later. The small "shrinelets" called caves 9A to 9D and 10A also date from the second period. These were commissioned by individuals. Cave 9 arch has remnant profile that suggests that it likely had wooden fittings. The cave has a distinct apsidal shape, nave, aisle and an apse with an icon, architecture, and plan that reminds one of the cathedrals built in Europe many centuries later. The aisle has a row of 23 pillars. The ceiling is vaulted. The stupa is at the center of the apse, with a circumambulation path around it. The stupa sits on a high cylindrical base. On the left wall of the cave are votaries approaching the stupa, which suggests a devotional tradition. According to Spink, the paintings in this cave, including the intrusive standing Buddhas on the pillars, were added in the 5th century. Above the pillars and also behind the stupa are colorful paintings of the Buddha with Padmapani and Vajrapani next to him, they wear jewels and necklaces, while yogis, citizens and Buddhist bhikshu are shown approaching the Buddha with garlands and offerings, with men wearing dhoti and turbans wrapped around their heads. On the walls are friezes of Jataka tales, but likely from the Hinayana phase of early construction. Some of the panels and reliefs inside as well as outside Cave 10 do not make narrative sense, but are related to Buddhist legends. This lack of narrative flow may be because these were added by different monks and official donors in the 5th century wherever empty space was available. This devotionalism and the worship hall character of this cave is the likely reason why four additional shrinelets 9A, 9B, 9C, and 9D were added between Cave 9 and 10. Cave 10 Cave 10, a vast prayer hall or Chaitya, is dated to about the 1st century BCE, together with the nearby vihara cave No 12. These two caves are thus among the earliest of the Ajanta complex. It has a large central apsidal hall with a row of 39 octagonal pillars, a nave separating its aisle and stupa at the end for worship. The stupa has a pradakshina patha (circumambulatory path). This cave is significant because its scale confirms the influence of Buddhism in South Asia by the 1st century BCE and its continued though declining influence in India through the 5th century CE. Further, the cave includes a number of inscriptions where parts of the cave are "gifts of prasada" by different individuals, which in turn suggests that the cave was sponsored as a community effort rather than a single king or one elite official. Cave 10 is also historically important because in April 1819, a British Army officer John Smith saw its arch and introduced his discovery to the attention of the Western audience. Chronology Several others caves were also built in Western India around the same period under royal sponsorship. It is thought that the chronology of these early Chaitya Caves is as follows: first Cave 9 at Kondivite Caves and then Cave 12 at the Bhaja Caves, which both predate Cave 10 of Ajanta. Then, after Cave 10 of Ajanta, in chronological order: Cave 3 at Pitalkhora, Cave 1 at Kondana Caves, Cave 9 at Ajanta, which, with its more ornate designs, may have been built about a century later, Cave 18 at Nasik Caves, and Cave 7 at Bedse Caves, to finally culminate with the "final perfection" of the Great Chaitya at Karla Caves. Inscription Cave 10 features a Sanskrit inscription in Brahmi script that is archaeologically important. The inscription is the oldest of the Ajanta site, the Brahmi letters being paleographically dated to circa the 2nd century BCE. It reads: Paintings The paintings in cave 10 include some surviving from the early period, many from an incomplete programme of modernisation in the second period, and a very large number of smaller late intrusive images for votive purposes, around the 479–480 CE, nearly all Buddhas and many with donor inscriptions from individuals. These mostly avoided over-painting the "official" programme and after the best positions were used up are tucked away in less prominent positions not yet painted; the total of these (including those now lost) was probably over 300, and the hands of many different artists are visible. The paintings are numerous and from two periods, many narrating the Jataka tales in a clockwise sequence. Both Hinayana and Mahayana stage paintings are discernable, though the former are more faded and begrimed with early centuries of Hinayana worship. Of interest here is the Saddanta Jataka tale – the fable about six tusked elephant, and the Shyama Jataka – the story about the man who dedicates his life serving his blind parents. According to Stella Kramrisch, the oldest layer of the Cave 10 paintings date from about 100 BCE, and the principles behind their composition are analogous to those from the same era at Sanchi and Amaravati. Cave 11 Cave 11 is a monastery (19.87 × 17.35 m) built during c. 462 to 478. The cave veranda has pillars with octagonal shafts and square bases. The ceiling of the veranda shows evidence of floral designs and eroded reliefs. Only the center panel is discernible wherein the Buddha is seen with votaries lining up to pray before him. Inside, the cave consists of a hall with a long rock bench opening into six rooms. Similar stone benches are found in Nasik Caves. Another pillared verandah ends in a sanctum with seated Buddha against an incomplete stupa, and has four cells. The cave has a few paintings showing Bodhisattvas and the Buddha. Of these, the Padmapani, a couple gathered to pray, a pair of peafowl, and a female figure painting have survived in the best condition. The sanctum of this cave may be among the last structures built at Ajanta because it features a circumambulation path around the seated Buddha. Cave 12 According to Archaeological Survey of India (ASI), Cave 12 is an early stage Hinayana (Theravada) monastery (14.9 × 17.82 m) from the 2nd to 1st century BCE. Spink however only dates it to the 1st century BCE. The cave is damaged with its front wall completely collapsed. Its three sides inside have twelve cells, each with two stone beds. Cave 13 Cave 13 is another small monastery from the early period, consisting of a hall with seven cells, each also with two stone beds, all carved out of the rock. Each cell has rock-cut beds for the monks. In contrast to ASI's estimate, Gupte and Mahajan date both these caves about two to three centuries later, between 1st and 2nd-century CE. Cave 14 Cave 14 is another unfinished monastery (13.43 × 19.28 m) but carved above Cave 13. The entrance door frame shows sala bhanjikas. Cave 15 Cave 15 is a more complete monastery (19.62 × 15.98 m) with evidence that it had paintings. The cave consists of an eight-celled hall ending in a sanctum, an antechamber and a verandah with pillars. The reliefs show the Buddha, while the sanctum Buddha is shown seated in the Simhasana posture. Cave 15 door frame has carvings of pigeons eating grain. Cave 15A Cave 15A is the smallest cave with a hall and one cell on each side. Its entrance is just to the right of the elephant-decorated entrance to Cave 16. It is an ancient Hinayana cave with three cells opening around a minuscule central hall. The doors are decorated with a rail and arch pattern. It had an inscription in an ancient script, which has been lost. Cave 16 Cave 16 occupies a prime position near the middle of site, and was sponsored by Varahadeva, minister of Vakataka king Harishena (r. ). He was a follower of Buddhism. He devoted it to the community of monks, with an inscription that expresses his wish, may "the entire world (...) enter that peaceful and noble state free from sorrow and disease" and affirming his devotion to the Buddhist faith: "regarding the sacred law as his only companion, (he was) extremely devoted to the Buddha, the teacher of the world". He was, states Spink, probably someone who revered both the Buddha and the Hindu gods, as he proclaims his Hindu heritage in an inscription in the nearby Ghatotkacha Cave. The 7th-century Chinese traveler Xuan Zang described the cave as the entrance to the site. Cave 16 (19.5 m × 22.25 m × 4.6 m) influenced the architecture of the entire site. Spink and other scholars call it the "crucial cave" that helps trace the chronology of the second and closing stages of the entire cave's complex construction. Cave 16 is a Mahayana monastery and has the standard arrangement of a main doorway, two windows, and two aisle doorways. The veranda of this monastery is 19.5 m × 3 m, while the main hall is almost a perfect square with 19.5 m side. The paintings in Cave 16 are numerous. Narratives include various Jataka tales such as Hasti, Mahaummagga and the Sutasoma fables. Other frescos depict the conversion of Nanda, miracle of Sravasti, Sujata's offering, Asita's visit, the dream of Maya, the Trapusha and Bhallika story, and the ploughing festival. The Hasti Jataka frescos tell the story of a Bodhisattva elephant who learns of a large group of people starving, then tells them to go below a cliff where they could find food. The elephant proceeds to sacrifice himself by jumping off that cliff thereby becoming food so that the people can survive. These frescos are found immediately to the left of entrance, in the front corridor and the narrative follows a clockwise direction. The Mahaummagga Jataka frescos are found on the left wall of the corridor, which narrates the story of a child Bodhisattva. Thereafter, in the left corridor is the legend surrounding the conversion of Nanda – the half brother of the Buddha. The story depicted is one of the two major versions of the Nanda legend in the Buddhist tradition, one where Nanda wants to lead a sensuous life with the girl he had just wed and the Buddha takes him to heaven and later hell to show the spiritual dangers of a sensual life. After the Nanda-related frescos, the cave presents Manushi Buddhas, followed by flying votaries with offerings to worship the Buddha and the Buddha seated in teaching asana and dharma chakra mudra. The right wall of the corridor show the scenes from the life of the Buddha. These include Sujata offering food to the Buddha with a begging bowl in white dress, Tapussa and Bhalluka next to the Buddha after they offering wheat and honey to the Buddha as monk, the future Buddha sitting alone under a tree, and the Buddha at a ploughing festival. One mural shows Buddha's parents trying to dissuade him from becoming a monk. Another shows the Buddha at the palace surrounded by men in dhoti and women in sari as his behavior presents the four signs that he is likely to renounce. On this side of the corridor are also paintings that show the future Buddha as a baby with sage Asita with rishi-like looks. According to Spink, some of the Cave 16 paintings were left incomplete. Cave 17 Cave 17 (34.5 m × 25.63 m) along with Cave 16 with two great stone elephants at the entrance and Cave 26 with sleeping Buddha, were some of the many caves sponsored by the Hindu Vakataka prime minister Varahadeva. Cave 17 had additional donors such as the local king Upendragupta, as evidenced by the inscription therein. The cave features a large and most sophisticated vihara design, along with some of the best-preserved and well-known paintings of all the caves. While Cave 16 is known for depicting the life stories of the Buddha, the Cave 17 paintings has attracted much attention for extolling human virtues by narrating the Jataka tales. The narration includes attention to details and a realism which Stella Kramrisch calls "lavish elegance" accomplished by efficient craftsmen. The ancient artists, states Kramrisch, tried to show wind passing over a crop by showing it bending in waves, and a similar profusion of rhythmic sequences that unroll story after story, visually presenting the metaphysical. The Cave 17 monastery includes a colonnaded porch, a number of pillars each with a distinct style, a peristyle design for the interior hall, a shrine antechamber located deep in the cave, larger windows and doors for more light, along with extensive integrated carvings of Indian gods and goddesses. The hall of this monastery is a square, with 20 pillars. The grand scale of the carving also introduced errors of taking out too much rock to shape the walls, states Spink, which led to the cave being splayed out toward the rear. Cave 17 has one long inscription by king Upendragupta, in which he explains that he has "expended abundant wealth" on building this vihara, bringing much satisfaction to the devotees. Altogether, Upendragupta is known to have sponsored at least 5 of the caves in Ajanta. He may have spent too much wealth on religious pursuits however, as he was ultimately defeated by the attacks of the Asmaka. Cave 17 has thirty major murals. The paintings of Cave 17 depict Buddha in various forms and postures – Vipasyi, Sikhi, Visvbhu, Krakuchchanda, Kanakamuni, Kashyapa and Sakyamuni. Also depicted are Avalokitesvara, the story of Udayin and Gupta, the story of Nalagiri, the Wheel of life, a panel celebrating various ancient Indian musicians and a panel that tells of Prince Simhala's expedition to Sri Lanka. The narrative frescos depict the various Jataka tales such as the Shaddanta, Hasti, Hamsa, Vessantara, Sutasoma, Mahakapi (in two versions), Sarabhamiga, Machchha, Matiposaka, Shyama, Mahisha, Valahassa, Sibi, Ruru and Nigrodamiga Jatakas. The depictions weave in the norms of the early 1st millennium culture and the society. They show themes as diverse as a shipwreck, a princess applying makeup, lovers in scenes of dalliance, and a wine drinking scene of a couple with the woman and man amorously seated. Some frescos attempt to show the key characters from various parts of a Jataka tale by co-depicting animals and attendants in the same scene. Cave 18 Cave 18 is a small rectangular space (3.38 × 11.66 m) with two octagonal pillars and it joins into another cell. Its role is unclear. Cave 19 (5th century CE) Cave 19 is a worship hall (chaitya griha, 16.05 × 7.09 m) datable to the fifth century CE. The hall shows painted Buddha, depicted in different postures. This worship hall is now visited through what was previously a carved room. The presence of this room before the hall suggests that the original plan included a mandala style courtyard for devotees to gather and wait, an entrance and facade to this courtyard, all of whose ruins are now lost to history. Cave 19 is one of the caves known for its sculpture. It includes Naga figures with a serpent canopy protecting the Buddha, similar to those found for spiritual icons in the ancient Jain and Hindu traditions. It includes Yaksha dvarapala (guardian) images on the side of its vatayana (arches), flying couples, sitting Buddha, standing Buddhas and evidence that its ceiling was once painted. Cave 19 drew upon on the plan and experimentation in Cave 9. It made a major departure from the earlier Hinayana tradition, by carving a Buddha into the stupa, a decision that states Spink must have come from "the highest levels" in the 5th-century Mahayana Buddhist establishment because the king and dynasty that built this cave was from the Shaivism Hindu tradition. Cave 19 excavation and stupa was likely in place by 467 CE, and its finishing and artistic work continued into the early 470s, but it too was an incomplete cave when it was dedicated in 471 CE. The entrance facade of the Cave 19 worship hall is ornate. Two round pillars with fluted floral patterns and carved garlands support a porch. Its capital is an inverted lotus connecting to an amalaka. To its left is standing Buddha in varada hasta mudra with a devotee prostrating at his feet. On right is a relief of woman with one hand holding a pitcher and other touching her chin. Above is a seated Buddha in meditating mudra. Towards the right of the entrance is the "Mother and Child" sculpture. A figure with begging bowl is the Buddha, watching him are his wife and son. The worship hall is apsidal, with 15 pillars dividing it into two side aisles and one nave. The round pillars have floral reliefs and a fluted shaft topped with Buddha in its capitals. Next, to the Buddha in the capitals are elephants, horses and flying apsara friezes found elsewhere in India, reflecting the style of the Gupta Empire artwork. According to Sharma, the similarities at the Karla Caves Great Chaitya, built in the 2nd century CE, suggest that Cave 19 may have been modeled after it. The walls and the ceiling of the side aisles inside the worship hall are covered with paintings. These show the Buddha, flowers, and in the left aisle the "Mother and Child" legend again. Cave 20 Cave 20 is a monastery hall (16.2 × 17.91 m) from the 5th century. Its construction, states Spink, was started in the 460s by king Upendragupta, with his expressed desire "to make the great tree of religious merit grow". The work on Cave 20 was pursued in parallel with other caves. Cave 20 has exquisite detailing, states Spink, but it was relatively lower on priority than Caves 17 and 19. The work on Cave 20 was intermittently stopped and then continued in the following decade. The vihara consists of a sanctum, four cells for monks and a pillared verandah with two stone cut windows for light. Prior to entering the main hall, on the left of veranda are two Buddhas carved above the window and side cell. The ceiling of the main hall has remnants of painting. The sanctum Buddha is in preaching posture. The cave is known for the sculpture showing seven Buddhas with attendants on its lintel. The cave has a dedicatory Sanskrit inscription in Brahmi script in its verandah, and it calls the cave as a mandapa. Many of the figural and ornamental carvings in Cave 20 are similar to Cave 19, and to a lesser degree to those found in Cave 17. This may be because the same architects and artisans were responsible for the evolution of the three caves. The door frames in Cave 20 are quasi-structural, something unique at the Ajanta site. The decorations are also innovative in Cave 20, such as one showing the Buddha seated against two pillows and "a richly laden mango tree behind him", states Spink. Cave 21 Cave 21 is a hall (28.56 × 28.03 m) with twelve rock-cut rooms for monks, a sanctum, twelve pillared and pilastered verandah. The carvings on the pilaster include those of animals and flowers. The pillars feature reliefs of apsaras, Nagaraja and Nagarani, as well as devotees bowing with the Anjali mudra. The hall shows evidence that it used to be completely painted. The sanctum Buddha is shown in preaching posture. Cave 22 Cave 22 is a small vihara (12.72 × 11.58 m) with a narrow veranda and four unfinished cells. It is excavated at a higher level and has to be reached by a flight of steps. Inside, the Buddha is seated in pralamba-padasana. The painted figures in Cave 22 show Manushi-Buddhas with Maitreya. A pilaster on the left side of the Cave 22 veranda has a Sanskrit prose inscription. It is damaged in parts, and the legible parts state that this is a "meritorious gift of a mandapa by Jayata", calling Jayata's family as "a great Upasaka", and ending the inscription with "may the merit of this be for excellent knowledge to all sentient beings, beginning with father and mother". Cave 23 Cave 23 is also unfinished, consisting of a hall (28.32 × 22.52 m) but a design similar to Cave 21. The cave differs in its pillar decorations and the naga doorkeepers. Cave 24 Cave 24 is like Cave 21, unfinished but much larger. It features the second largest monastery hall (29.3 × 29.3 m) after Cave 4. The cave 24 monastery has been important to scholarly studies of the site because it shows how multiple crews of workers completed their objectives in parallel. The cell construction began as soon as the aisle had been excavated and while the main hall and sanctum were under construction. The construction of Cave 24 was planned in 467 CE, but likely started in 475 CE, with support from Buddhabhadra, then abruptly ended in 477 with the sponsor king Harisena's death. It is significant in having one of the most complex capitals on a pillar at the Ajanta site, an indication of how the artists excelled and continuously improved their sophistication as they worked with the rock inside the cave. The artists carved fourteen complex miniature figures on the central panel of the right center porch pillar, while working in dim light in a cramped cave space. The medallion reliefs in Cave 24 similarly show loving couples and anthropomorphic arts, rather than flowers of earlier construction. Cave 24's sanctum has a seated Buddha in pralamba-padasana. Cave 25 Cave 25 is a monastery. Its hall (11.37 × 12.24 m) is similar to other monasteries, but has no sanctum, includes an enclosed courtyard and is excavated at an upper level. Cave 26 (5th century CE) Cave 26 is a worship hall (chaityagriha, 25.34 × 11.52 m) similar in plan to Cave 19. It is much larger and with elements of a vihara design. An inscription states that a monk Buddhabhadra and his friend minister serving king of Asmaka gifted this vast cave. The inscription includes a vision statement and the aim to make "a memorial on the mountain that will endure for as long as the moon and the sun continue", translates Walter Spink. It is likely that the builders focussed on sculpture, rather than paintings, in Cave 26 because they believed stone sculpture will far more endure than paintings on the wall. The sculptures in Cave 26 are elaborate and more intricate. It is among the last caves excavated, and an inscription suggests late 5th or early 6th century according to ASI. The cave consists of an apsidal hall with side aisles for circumambulation (pradikshana). This path is full of carved Buddhist legends, three depictions of the Miracle of Sravasti in the right ambulatory side of the aisle, and seated Buddhas in various mudra. Many of these were added later by devotees, and therefore are intrusive to the aims of the original planners. The artwork begins on the wall of the aisle, immediately the left side of entrance. The major artworks include the Mahaparinirvana of Buddha (reclining Buddha) on the wall, followed by the legend called the "Temptations by Mara". The temptations include the seduction by Mara's daughters who are depicted below the meditating Buddha. They are shown scantly dressed and in seductive postures, while on both the left and right side of the Buddha are armies of Mara attempting to distract him with noise and threaten him with violence. In the top right corner is the image of a dejected Mara frustrated by his failure to disturb the resolve or focus of the ascetic Buddha. At the center of the apse is a rock-cut stupa. The stupa has an image of the Buddha on its front, 18 panels on its base, 18 panels above these, a three tiered torana above him, and apsaras are carved on the anda (hemispherical egg) stupa. On top of the dagoba is a nine-tiered harmika, a symbolism for the nine saṃsāra (Buddhism) heavens in Mahayana cosmology. The walls, pillars, brackets and the triforium are extensively carved with Buddhist themes. Many of the wall reliefs and images in this cave were badly damaged, and have been restored as a part of the site conservation efforts. Between cave 26 and its left wing, there is an inscription by a courtier of Rashtrakuta Nanaraj (who is mentioned in the Multai and Sangaloda plates), from late 7th or early 8th century. It is the last inscription in Ajanta. Cave 27 Cave 27 is a monastery and may have been planned as an attachment to Cave 26. Its two storeys are damaged, with the upper level partially collapsed. Its plan is similar to other monasteries. Cave 28 Cave 28 is an unfinished monastery, partially excavated, at the westernmost end of the Ajanta complex and barely accessible. Cave 29 Cave 29 an unfinished monastery at the highest level of the Ajanta complex, apparently unnoticed when the initial numbering system was established, and physically located between Caves 20 and 21. Cave 30 In 1956, a landslide covered the footpath leading to Cave 16. In the attempts to clear and restore the walkway, a small aperture and votive stupa were noticed in the debris by the workers, in a location near the stream bed. Further tracing and excavations led to a previously unknown Hinayana monastery cave dated to the 2nd and 1st century BCE. Cave 30 may actually be the oldest cave of the Ajanta complex. It is a 3.66 m × 3.66 m cave with three cells, each with two stone beds and stone pillows on the side of each cell. The cell door lintels show lotus and garland carvings. The cave has two inscriptions in an unknown script. It also has a platform on its veranda with a fine view of the river ravine below and the forest cover. According to Gupte and Mahajan, this cave may have been closed at some point with large carefully carved pieces as it distracted the entrance view of Cave 16. Other infrastructure Over 80% of the Ajanta caves were vihara (temporary traveler residences, monasteries). The designers and artisans who built these caves included facilities for collecting donations and storing grains and food for the visitors and monks. Many of the caves include large repositories cut into the floor. The largest storage spaces are found, states Spink, in the "very commodious recesses in the shrines of both Ajanta Cave Lower 6 and Cave 11". These caves were probably chosen because of their relative convenience and the security they offered due to their higher level. The choice of integrating covered vaults cut into the floor may have been driven by the need to provide sleeping space and logistical ease. Recent excavations A burnt-brick vihara monastery facing the caves on the right bank of the river Waghora has been recently excavated. It has a number of cells facing a central courtyard, in which a stupa was established. A coin of the Western Satraps ruler Visvasena (ruled 293–304 CE) as well as a gold coin of the Byzantine Emperor Theodosius II (ruled 402-450 CE) were found in the excavations, giving further numismatic confirmation for the dating of the caves. A terracotta plaque of Mahishasuramardini was also found, which was possibly under worship by the artisans. Copies of the paintings The paintings have deteriorated significantly since they were rediscovered, and a number of 19th-century copies and drawings are important for a complete understanding of the works. A number of attempts to copy the Ajanta paintings began in the 19th century for European and Japanese museums. Some of these works have later been lost in natural and fire disasters. In 1846 for example, Major Robert Gill, an Army officer from Madras Presidency and a painter, was appointed by the Royal Asiatic Society to make copies of the frescos on the cave walls. Gill worked on his painting at the site from 1844 to 1863. He made 27 copies of large sections of murals, but all but four were destroyed in a fire at the Crystal Palace in London in 1866, where they were on display. Gill returned to the site, and recommenced his labours, replicating the murals until his death in 1875. Another attempt was made in 1872 when the Bombay Presidency commissioned John Griffiths to work with his students to make copies of Ajanta paintings, again for shipping to England. They worked on this for thirteen years and some 300 canvases were produced, many of which were displayed at the Imperial Institute on Exhibition Road in London, one of the forerunners of the Victoria and Albert Museum. But in 1885 another fire destroyed over a hundred of the paintings in storage in a wing of the museum. The V&A still has 166 paintings surviving from both sets, though none have been on permanent display since 1955. The largest are some . A conservation project was undertaken on about half of them in 2006, also involving the University of Northumbria. Griffith and his students had painted many of the paintings with "cheap varnish" in order to make them easier to see, which has added to the deterioration of the originals, as has, according to Spink and others, recent cleaning by the ASI. A further set of copies were made between 1909 and 1911 by Christiana Herringham (Lady Herringham) and a group of students from the Calcutta School of Art that included the future Indian Modernist painter Nandalal Bose. The copies were published in full colour as the first publication of London's fledgling India Society. More than the earlier copies, these aimed to fill in holes and damage to recreate the original condition rather than record the state of the paintings as she was seeing them. According to one writer, unlike the paintings created by her predecessors Griffiths and Gill, whose copies were influenced by British Victorian styles of painting, those of the Herringham expedition preferred an 'Indian Renascence' aesthetic of the type pioneered by Abanindranath Tagore. Early photographic surveys were made by Robert Gill, whose photos, including some using stereoscopy, were used in books by him and Fergusson (many are available online from the British Library), then Victor Goloubew in 1911 and E.L. Vassey, who took the photos in the four volume study of the caves by Ghulam Yazdani (published 1930–1955). Some slightly creative copies of Ajanta frescos, especially the painting of the Adoration of the Buddha from the shrine antechamber of Cave 17, were commissioned by Thomas Holbein Hendley (1847–1917) for the decoration of the walls of the hall of the Albert Hall Museum, Jaipur, India. He had the work painted by a local artist variously named Murli or Murali. The museum was opened to the public in 1887. This work is otherwise presented as characteristic of the end of the 19th century. Another attempt to make copies of the murals was made by the Japanese artist Arai Kampō (荒井寛方:1878–1945) after being invited by Rabindranath Tagore to India to teach Japanese painting techniques. He worked on making copies with tracings on Japanese paper from 1916 to 1918 and his work was conserved at Tokyo Imperial University until the materials perished during the 1923 Great Kantō earthquake. Significance Natives, society and culture in the arts at Ajanta The Ajanta cave arts are a window into the culture, society and religiosity of the native population of India between the 2nd century BCE and 5th century CE. Different scholars have variously interpreted them from the perspective of gender studies, history, sociology, and the anthropology of South Asia. The dress, the jewelry, the gender relations, the social activities depicted showcase at least a lifestyle of the royalty and elite, and in others definitely the costumes of the common man, monks and rishi depicted therein. They shine "light on life in India" around mid 1st millennium CE. The Ajanta artworks provide a contrast between the spiritual life of monks who had given up all materialistic possessions versus the sensual life of those it considered materialistic, luxurious, symbols of wealth, leisurely and high fashion. Many frescos show scenes from shops, festivals, jesters at processions, palaces and performance art pavilions. These friezes share themes and details of those found in Bharhut, Sanchi, Amaravati, Ellora, Bagh, Aihole, Badami and other archaeological sites in India. Ajanta caves contributes to visual and descriptive sense of the ancient and early medieval Indian culture and artistic traditions, particularly those around the Gupta Empire era period. The early colonial era description of Ajanta caves was largely orientalist and critical, inconsistent with the Victorian values and stereotyping. According to William Dalrymple, the themes and arts in the Ajanta caves were puzzling to the 19th-century Orientalists. Lacking the Asian cultural heritage and with no knowledge of Jataka Tales or equivalent Indian fables, they could not comprehend it. They projected their own views and assumptions, calling it something that lacks reason and rationale, something that is meaningless crude representation of royalty and foreigners with mysticism and sensuousness. The 19th-century views and interpretations of the Ajanta Caves were conditioned by ideas and assumptions in the colonial mind, saw what they wanted to see. To many who are unaware of the premises of Indian religions in general, and Buddhism in particular, the significance of Ajanta Caves has been like rest of Indian art. According to Richard Cohen, Ajanta Caves to them has been yet another example of "worship this stock, or that stone, or monstrous idol". In contrast, to the Indian mind and the larger Buddhist community, it is everything that art ought to be, the religious and the secular, the spiritual and the social fused to enlightened perfection. According to Walter Spink – one of the most respected Art historians on Ajanta, these caves were by 475 CE a much-revered site to the Indians, with throngs of "travelers, pilgrims, monks and traders". The site was vastly transformed into its current form in just 20 years, between early 460 CE to early 480 CE, by regional architects and artisans. This accomplishment, states Spink, makes Ajanta, "one of the most remarkable creative achievements in man's history". Foreigners in the paintings of Ajanta The Ajanta Caves painting are a significant source of socio-economic information in ancient India, particularly in relation to the interactions of India with foreign cultures at the time most of the paintings were made, in the 5th century CE (Common Era). According to Indian historian Haroon Khan Sherwani: "The paintings at Ajanta clearly demonstrate the cosmopolitan character of Buddhism, which opened its way to men of all races, Greek, Persian, Saka, Pahlava, Kushan and Huna". Depictions of foreigners abound: according to Spink, "Ajanta's paintings are filled with such foreign types." They have sometimes been a source of misinterpretation as in the so-called "Persian Embassy Scene". These foreigners may reflect the Sassanian merchants, visitors and the flourishing trade routes of the day. The so-called "Persian Embassy Scene" Cave 1, for example, shows a mural fresco with characters with foreigner faces or dresses, the so-called "Persian Embassy Scene". This scene is located at the right of the entrance door upon entering the hall. According to Spink, James Fergusson, a 19th-century architectural historian, had decided that this scene corresponded to the Persian ambassador in 625 CE to the court of the Hindu Chalukya king Pulakeshin II. An alternate theory has been that the fresco represents a Hindu ambassador visiting the Persian king Khusrau II in 625 CE, a theory that Fergusson disagreed with. These assumptions by colonial British era art historians, state Spink and other scholars, has been responsible for wrongly dating this painting to the 7th century, when in fact this reflects an incomplete Harisena-era painting of a Jataka tale (the Mahasudarsana jataka, in which the enthroned king is actually the Buddha in one of his previous lives as King) with the representation of trade between India and distant lands such as Sassanian near East that was common by the 5th century. International trade, growth of Buddhism Cave 1 has several frescos with characters with foreigners' faces or dresses. Similar depictions are found in the paintings of Cave 17. Such murals, states Pia Brancaccio, suggest a prosperous and multicultural society in 5th-century India active in international trade. These also suggest that this trade was economically important enough to the Deccan region that the artists chose to include it with precision. Additional evidence of international trade includes the use of the blue lapis lazuli pigment to depict foreigners in the Ajanta paintings, which must have been imported from Afghanistan or Iran. It also suggests, states Branacaccio, that the Buddhist monastic world was closely connected with trading guilds and the court culture in this period. A small number of scenes show foreigners drinking wine in Caves 1 and 2. Some show foreign Near East kings with wine and their retinue which presumably add to the "general regal emphasis" of the cave. According to Brancaccio, the Ajanta paintings show a variety of colorful, delicate textiles and women making cotton. Textile probably was one of the major exports to foreign lands, along with gems. These were exported first through the Red Sea, and later through the Persian Gulf, thereby bringing a period of economic and cultural exchange between the Indians, the Sasanian Empire and the Persian merchants before Islam was founded in the Arabian peninsula. While scholars generally agree that these murals confirm trade and cultural connections between India and Sassanian west, their specific significance and interpretation varies. Brancaccio, for example, suggests that the ship and jars in them probably reflect foreign ships carrying wine imported to India. In contrast, Schlinghoff interprets the jars to be holding water, and ships shown as Indian ships used in international trade. Similar depictions are found in the paintings of Cave 17, but this time in direct relation to the worship of the Buddha. In Cave 17, a painting of the Buddha descending from the Trayastrimsa Heaven shows he being attended by many foreigners. Many foreigners in this painting are thus shown as listeners to the Buddhist Dharma. The ethnic diversity is depicted in the painting in the clothes (kaftans, Sasanian helmets, round caps), hairdos and skin colors. In the Visvantara Jataka of Cave 17, according to Brancaccio, the scene probably shows a servant from Central Asia holding a foreign metal ewer, while a dark-complexioned servant holds a cup to an amorous couple. In another painting in Cave 17, relating to the conversion of Nanda, a man possibly from northeast Africa appears as a servant. These representations show, states Brancaccio, that the artists were familiar with people of Sogdia, Central Asia, Persia and possibly East Africa. Another hypothesis is offered by Upadhya, who states that the artists who built Ajanta caves "very probably included foreigners". Impact on later painting and other arts The Ajanta paintings, or more likely the general style they come from, influenced painting in Tibet and Sri Lanka. Some influences from Ajanta have also suggested in the Kizil Caves of the Tarim Basin, in particular in early caves such as the Peacock Cave. The rediscovery of ancient Indian paintings at Ajanta provided Indian artists with examples from ancient India to follow. Nandalal Bose experimented with techniques to follow the ancient style which allowed him to develop his unique style. Abanindranath Tagore and Syed Thajudeen also used the Ajanta paintings for inspiration. Anna Pavlova's ballet Ajanta's Frescoes was inspired by her visit to Ajanta, choreographed by Ivan Clustine, with music by Nikolai Tcherepnin (one report says Mikhail Fokine in 1923). and premiered at Covent Garden in 1923. Jewish American poet Muriel Rukeyser wrote about the caves in "Ajanta," the opening poem of her third collection Beast in View (1944). Rukeyser was inspired in part by writings on the caves by artist Mukul Dey in 1925 and art historian Stella Kramrisch in 1937.

Afyonkarahisar (, "poppy, opium", kara "black", hisar "fortress") is a city in western Turkey. It is the administrative centre of Afyonkarahisar Province and Afyonkarahisar District. Its population is 251,799 (2021). Afyon is in the mountainous countryside inland from the Aegean coast, south-west of Ankara along the Akarçay River. In Turkey, Afyonkarahisar stands out as a capital city of hot springs and spas, an important junction of railway, highway and air traffic in West-Turkey, and the place where independence was won. In addition, Afyonkarahisar is one of the top leading provinces in agriculture, globally renowned for its marble and is the world's largest producer of pharmaceutical opium. In antiquity the city was called Akroinon and it is the side of Afyonkarahisar Castle. Etymology The name Afyon Kara Hisar literally means opium black castle in Turkish, since opium was widely grown here and there is a castle on a black rock. Also known simply as Afyon. Older spellings include Karahisar-i Sahip, Afium-Kara-hissar and Afyon Karahisar. The city was known as Afyon (opium), until the name was changed to Afyonkarahisar by the Turkish Parliament in 2004. History Ancient times The top of the rock in Afyon has been fortified for a long time. It was known to the Hittites as Hapanuwa, and was later occupied by Phrygians, Lydians and Achaemenid Persians until it was conquered by Alexander the Great. After the death of Alexander the city (now known as Akroinοn (Ακροϊνόν) or Nikopolis (Νικόπολις) in Ancient Greek), was ruled by the Seleucids and the kings of Pergamon, then Rome and Byzantium. Medieval period Akroinοn became an important fortress in the Armeniakon theme due to its strategic location and natural defences and was first mentioned in Byzantine history when it was attacked in 716 and 732 by Arabs invaders. The Byzantine emperor Leo III renamed the city Nicopolis (Greek for "city of victory") after his victory over Arab besiegers under Abdallah al-Battal (who would become the famous Turkish literature figure of Battal Gazi) in 740. Since the 10th century it was also a bishopric of Phrygia Salutaris. After 1071 the town became part of the frontier zone between the Byzantine Empire and the invading Turks. The city was still held by the former in 1112 but was lost to the Sultanate of Rum at some time before 1146 when Manuel I Komnenos won a vicotry here. The Turks were unable to firmly control the city until around 1210, renaming it to Kara Hissar ("black castle") after the ancient fortress situated upon a volcanic rock 201 meters above the town. Following the dispersal of the Seljuqs the town was occupied by the Sâhib Ata and then the Germiyanids. The castle was finally conquered by the Ottoman Sultan Beyazid I in 1392 but was lost after the invasion of Timur Lenk in 1402. It was recaptured in 1428 or 1429. Modern times The area thrived during the Ottoman Empire, as the centre of opium production and Afyon became a wealthy city. From 1867 until 1922, Afyon was part of the Hüdavendigâr vilayet of the Ottoman Empire. In 1902, a fire burning for 32 hours destroyed parts of the city. During the 1st World War British prisoners of war who had been captured at Gallipoli were housed here in an empty Armenian church at the foot of the rock. During the Greco-Turkish War (1919-1922) campaign (part of the Turkish War of Independence) Afyon and the surrounding hills were occupied by Greek forces. However, it was recovered on 27 August 1922, a key moment in the Turkish counter-attack in the Aegean region. After 1923 Afyon became a part of the Republic of Turkey. The region was a major producer of raw opium (hence the name Afyon) until the late 1960s when under international pressure, from the US in particular, the fields were burnt and production ceased. Now poppies are grown under a strict licensing regimen. They do not produce raw opium any more but derive Morphine and other opiates using the poppy straw method of extraction. Afyon was depicted on the reverse of the Turkish 50 lira banknote of 1927–1938. Economy The economy of Afyonkarahisar is based on agriculture, industries and thermal tourism. Especially its agriculture is strongly developed from the fact, a large part of its population living in the countrysides. Which stimulated agricultural activities greatly. Marble Afyonkarahisar produces an important chunk of Turkish processed marbles, it ranks second on processed marble exports and fourth on travertine. Afyon holds an important share of Turkish marble reserves, with some 12,2% of total Turkish reserves. Historically marble from Afyon was generally referred to as "Docimeaen marble" due to the place where it was mined, Docimium. Afyon has unique marble types and colors, which were historically very renown and are unique to Afyon such as "Afyon white", historically known as "Synnadic white", "Afyon Menekse", historically known as "Pavonazzetto", and "Afyon kaplan postu", a less popular type. Docimian marble was highly admired and valued for its unique colors and fine grained quality by ancient people such as the Romans. When the Romans took control over Docimaean quarries, they were impressed by the beautiful color combinations of the Docimaean Pavonazzetto, which is a type of white marble with purple veins. Emperors such as Augustus, Trajan and Hadrian made extensive use of Docimaean marble to many of their major building projects. These include the Pantheon, Trajan's Forum and the Basilica Aemilia. Thermal sector The geography of Afyon has great geothermal activity. Hence, the place has plenty of thermal springs. There are five main springs and all of them have high mineral content with temperatures ranging between 40 and 100 °C. The waters have strong healing properties to some diseases. As a result, plenty of thermal facilities formed over time. In time, Afyon has developed its thermal sector with more capacity, comfort and innovation. Afyon combined the traditional bath houses with 5-star resorts, the health benefits of the natural springs have put the thermal resorts further then a mere attraction. Hospitals and universities have come in association with thermal resorts, to utilize the full health potentials of the thermals. As such, Afyon Kocatepe University Physical Therapy and Rehabilitation Hospital opened for that purpose. Afyon now has the largest residence capacity of thermal resorts, of which a large part are 5-star thermal hotels which give medical care with qualified personnel. Spa water Kızılay, was the first mineral water factory in Turkey which opened in Afyon, in 1926 by Atatürk. After the mineral water from Gazligöl springs, healed Atatürk's kidneys and proved its health benefits. Since its foundation, "Kızılay Spa Water" grew as the biggest spa water distributor in Turkey, Middle-East and Balkans. Pharmaceuticals and morphine Almost a third of all the morphine produced in the world derives from alkaloids factory in Afyon, named as "Afyon Alkaloids". this large capacity is the byproduct of Afyon's poppy plantations. The pharmaceuticals derive from the opium of the poppy capsules. "Afyon Alkaloids" factory is the largest of its kind in the world, with high capacity processing ability and modern laboratories. The raw opium is put through a chain of biochemical processes, resulting into several types of morphine. In the Alkaloid Extraction Unit only base morphine is produced. In the adjacent Derivatives Unit half of the morphine extracted is converted to morphine hydrochloride, codeine, codeine phosphate, codeine sulphate, codeine hydrochloride, morphine sulphate, ethylmorphine hydrochloride. Agriculture Livestocks Afyon breeds a large amount of livestocks, its landscape and demography is suitable for this field. As such it ranks in the top 10 within Turkey in terms of amounts of sheep and cattle it has. Meat and meat products As a result of being an important source of livestock, related sectors such as meat and meat products are also very productive in Afyon. Its one of the leading provinces in red meat production and has very prestigious brand marks of sausages, such as "Cumhuriyet Sausages". Eggs Afyon is the sole leader in egg production within Turkey. It has the largest amount of laying hens, with a figure of 12,7 million. And produces a record amount of 6 million eggs per day. Cherries and sour cherries Sour cherries are cultivated in Afyon in very large numbers, so much so that it became very iconic to Afyon. Every year, a sour cherry festival takes place in the Cay district. It is the largest producer of sour cherries in Turkey. The sour cherries grown in Afyon are of excellent quality because of the ideal climate they're grown in. For the same reason Afyon is also an ideal place for cherry cultivation. First quality cherries known as "Napolyon Cherries" are grown in abundance, its one of the top 5 leading provinces. Poppy One of the iconic agricultural practices of Afyon is the cultivation of poppy. Afyon's climate is ideal for the cultivation of this plant, hence a large amount of poppy plantation occurs in this region. Though, a strong limitation came some decades ago from international laws, cause of the opium content of poppy plants peels. Nevertheless, Afyon is the largest producer of poppy in Turkey and accounts for a large amount of global production. Potatoes and sugar-beets Afyon has a durable reputation in potato production, it produces around 8% of Turkish potato need. It ranks in the top 5 in potato, sugar-beets, cucumber and barley production. Climate Afyonkarahisar has a Mediterranean climate (Csa) under the Köppen classification and an oceanic climate with a warm summer and a cool winter (Dobk) under the Trewartha classification. The winters are cool and the summers are warm and dry with cool nights. Rainfall occurs mostly during the spring and autumn. Afyon today Afyon is the centre of an agricultural area and the city has a country town feel to it. There is little in the way of bars, cafes, live music or other cultural amenities, and the standards of education are low for a city in the west of Turkey. Nonetheless, the city does host one seat of higher education, Afyon Kocatepe University. Afyon is known for its marble (in 2005 there were 355 marble quarries in the province of Afyon producing high quality white stone), its sucuk (spiced sausages), its kaymak (meaning either cream or a white Turkish delight) and various handmade weavings. There is also a large cement factory. This is a natural crossroads, the routes from Ankara to İzmir and from Istanbul to Antalya intersect here and Afyon is a popular stopping-place on these journeys. There are a number of well-established roadside restaurants for travellers to breakfast on the local cuisine. Some of these places are modern well-equipped hotels and spas; the mineral waters of Afyon are renowned for their healing qualities. There is also a long string of roadside kiosks selling the local Turkish delight. Transport Afyon is also an important rail junction between İzmir, Konya, Ankara and Istanbul. Afyon is on the route of the planned high-speed rail line between Ankara and Izmir.Zafer Airport, located 60 km from city center, serves Afyonkarahisar.

Abd al-Rahman I ibn Mu’awiya (in full: Abd al-Rahman ibn Mu'awiya ibn Hisham ibn Abd al-Malik ibn Marwan; 7 March 731 – 30 September 788; Arabic: عبد الرحمن الأول) was the founder of the Umayyad dynasty that ruled the greater part of Iberia in Al-Andalus for nearly three centuries (including the succeeding Caliphate of Córdoba). Abd al-Rahman was a member of the Umayyad dynasty in Damascus, and his establishment of a government in Iberia represented a break with the Abbasids, who had overthrown the Umayyads in Damascus in 750. He was also known by the surnames al-Dakhil ("the Entrant"), Saqr Quraish ("the Falcon of Quraysh") and as Saqr al-Andalus ("the Falcon of Andalusia"). Variations of the spelling of his name include Abd ar-Rahman, Abdul Rahman I, Abdar Rahman, and Abderraman. Biography Flight from Damascus Abd al-Rahman was born in Palmyra, near Damascus in the heartland of the Umayyad Caliphate, the son of the Umayyad prince Mu'awiya ibn Hisham and his concubine Raha, a Berber woman from the Nafza tribe, and thus the grandson of Hisham ibn Abd al-Malik, caliph from 724 to 743.<ref>Arnold Joseph Toynbee, A study of history, Oxford University Press, H. Milford, 1934, Volume 8, p. 372</ref> He was twenty when his family, the ruling Umayyads, were overthrown by the Abbasid Revolution in 748–750. Abd al-Rahman and a small part of his family fled Damascus, where the center of Umayyad power had been; people moving with him included his brother Yahya, his four-year-old son Sulayman, and some of his sisters, as well as his Greek mawla (freedman or client), Bedr. The family fled from Damascus to the River Euphrates. All along the way the path was filled with danger, as the Abbasids had dispatched horsemen across the region to try to find the Umayyad prince and kill him. The Abbasids were merciless with all Umayyads that they found. Abbasid agents closed in on Abd al-Rahman and his family while they were hiding in a small village. He left his young son with his sisters and fled with Yahya. Accounts vary, but Bedr likely escaped with Abd al-Rahman. Some histories indicate that Bedr met up with Abd al-Rahman at a later date. Abd al-Rahman, Yahya, and Bedr quit the village, narrowly escaping the Abbasid assassins. On the way south, Abbasid horsemen again caught up with the trio. Abd al-Rahman and his companions then threw themselves into the River Euphrates. The horsemen urged them to return, promising that no harm would come to them; and Yahya, perhaps from fear of drowning, turned back. The 17th-century historian Ahmed Mohammed al-Maqqari poignantly described Abd al-Rahman's reaction as he implored Yahya to keep going: "O brother! Come to me, come to me!" Yahya returned to the near shore, and was quickly dispatched by the horsemen. They cut off his head and left his body to rot. Al-Maqqari quotes earlier historians reporting that Abd al-Rahman was so overcome with fear that from the far shore he ran until exhaustion overcame him. Only he and Bedr were left to face the unknown. Exile years After barely escaping with their lives, Abd al-Rahman and Bedr continued south through Palestine, the Sinai, and then into Egypt. Abd al-Rahman had to keep a low profile as he traveled. It may be assumed that he intended to go at least as far as northwestern Africa (Maghreb), the land of his mother, which had been partly conquered by his Umayyad predecessors. The journey across Egypt would prove perilous. At the time, Abd al-Rahman ibn Habib al-Fihri was the semi-autonomous governor of Ifriqiya (roughly, modern Tunisia) and a former Umayyad vassal. The ambitious Ibn Habib, a member of the illustrious Fihrid family, had long sought to carve out Ifriqiya as a private dominion for himself. At first, he sought an understanding with the Abbasids, but when they refused his terms and demanded his submission, Ibn Habib broke openly with the Abbasids and invited the remnants of the Umayyad dynasty to take refuge in his dominions. Abd al-Rahman was only one of several surviving Umayyad family members to make their way to Ifriqiya at this time. But Ibn Habib soon changed his mind. He feared the presence of prominent Umayyad exiles in Ifriqiya, a family more illustrious than his own, might become a focal point for intrigue among local nobles against his own usurped powers. Around 755, believing he had discovered plots involving some of the more prominent Umayyad exiles in Kairouan, Ibn Habib turned against them. At the time, Abd al-Rahman and Bedr were keeping a low profile, staying in Kabylie, at the camp of a Nafza Berber chieftain friendly to their plight. Ibn Habib dispatched spies to look for the Umayyad prince. When Ibn Habib's soldiers entered the camp, the Berber chieftain's wife Tekfah hid Abd al-Rahman under her personal belongings to help him go unnoticed. Once they were gone, Abd al-Rahman and Bedr immediately set off westwards. In 755, Abd al-Rahman and Bedr reached modern-day Morocco near Ceuta. Their next step would be to cross the sea to al-Andalus, where Abd al-Rahman could not have been sure whether or not he would be welcomed. Following the Berber Revolt of the 740s, the province was in a crisis, with the Muslim community torn by tribal dissensions among the Arabs (the Qays–Yemeni feud) and racial tensions between the Arabs and Berbers. At that moment, the nominal ruler of al-Andalus, emir Yusuf ibn Abd al-Rahman al-Fihri—another member of the Fihrid family and a favorite of the old Arab settlers (baladiyun), mostly of south Arabian or "Yemeni" tribal stock—was locked in a contest with his vizier (and son-in-law) al-Sumayl ibn Hatim al-Kilabi, the head of the "Syrians"—the shamiyun, drawn from the junds or military regiments of Syria, mostly of north Arabian Qaysid tribes—who had arrived in 742. Among the Syrian junds were contingents of old Umayyad clients, numbering perhaps 500, and Abd al-Rahman believed he might tug on old loyalties and get them to receive him. Bedr was dispatched across the straits to make contact. Bedr managed to line up three Syrian commanders—Ubayd Allah ibn Uthman and Abd Allah ibn Khalid, both originally of Damascus, and Yusuf ibn Bukht of Qinnasrin. The trio approached the Syrian arch-commander al-Sumayl (then in Zaragoza) to get his consent, but al-Sumayl refused, fearing Abd al-Rahman would try to make himself emir. As a result, Bedr and the Umayyad clients sent out feelers to their rivals, the Yemeni commanders. Although the Yemenis were not natural allies (the Umayyads are a Qaysid tribe), their interest was piqued. The emir Yusuf al-Fihri had proven himself unable to keep the powerful al-Sumayl in check and several Yemeni chieftains felt their future prospects were poor, whether in a Fihrid or Syrian-dominated Spain, so that they had a better chance of advancement if they hitched themselves to the glitter of the Umayyad name. Although the Umayyads did not have a historical presence in the region (no member of the Umayyad family was known to have ever set foot in al-Andalus before) and there were grave concerns about young Abd al-Rahman's inexperience, several of the lower-ranking Yemeni commanders felt they had little to lose and much to gain, and agreed to support the prince. Bedr returned to Africa to tell Abd al-Rahman of the invitation of the Umayyad clients in al-Andalus. Shortly thereafter, they set off with a small group of followers for Europe. When some local Berber tribesmen learned of Abd al-Rahman's intent to set sail for al-Andalus, they quickly rode to catch up with him on the coast. The tribesmen might have figured that they could hold Abd al-Rahman as hostage, and force him to buy his way out of Africa. He did indeed hand over some amount of dinars to the suddenly hostile local Berbers. Just as Abd al-Rahman launched his boat, another group of Berbers arrived. They also tried to obtain a fee from him for leaving. One of the Berbers held on to Abd al-Rahman's vessel as it made for al-Andalus, and allegedly had his hand cut off by one of the boat's crew. Abd al-Rahman landed at Almuñécar in al-Andalus, to the east of Málaga, in September 755; however, his landing site was unconfirmed. Fight for power Upon landing in Torrox, al-Andalus, Abd al-Rahman was greeted by clients Abu Uthman and Ibn Khalid and an escort of 300 cavalry. During his brief time in Málaga, he was able to amass local support quickly. Waves of people made their way to Málaga to pay respect to the prince they thought was dead, including many of the aforementioned Syrians. One famous story that persisted through history related to a gift Abd al-Rahman was given while in Málaga. The gift was a beautiful young slave girl, but Abd al-Rahman humbly returned her to her previous master. News of the prince's arrival spread like wildfire throughout the peninsula. During this time, emir al-Fihri and the Syrian commander al-Sumayl pondered what to do about the new threat to their shaky hold on power. They decided to try to marry Abd al-Rahman into their family. If that did not work, then Abd al-Rahman would have to be killed. Abd al-Rahman was apparently sagacious enough to expect such a plot. In order to help speed his ascension to power, he was prepared to take advantage of the feuds and dissensions. However, before anything could be done, trouble broke out in northern al-Andalus. Zaragoza, an important trade city on the Upper March of al-Andalus, made a bid for autonomy. Al-Fihri and al-Sumayl rode north to quash the rebellion. This might have been fortunate timing for Abd al-Rahman, since he was still getting a solid foothold in al-Andalus. By March 756, Abd al-Rahman and his growing following of Umayyad clients and Yemeni junds, were able to take Sevilla without violence. He managed to break the rebellion attempt in Zaragoza, but just about that time the Cordovan governor received news of a Basque rebellion in Pamplona. An important detachment was sent by Yusuf ibn 'Abd al-Rahman to quash it, but his troops were annihilated. After the setback, al-Fihri turned his army back south to face the "pretender". The fight for the right to rule al-Andalus was about to begin. The two contingents met on opposite sides of the River Guadalquivir, just outside the capital of Córdoba on the plains of Musarah. The river was, for the first time in years, overflowing its banks, heralding the end of a long drought. Nevertheless, food was still scarce, and Abd al-Rahman's army suffered from hunger. In an attempt to demoralize Abd al-Rahman's troops, al-Fihri ensured that his troops not only were well fed, but also ate gluttonous amounts of food in full view of the Umayyad lines. An attempt at negotiations soon followed in which it is likely that Abd al-Rahman was offered the hand of al-Fihri's daughter in marriage and great wealth. Abd al-Rahman, however, would settle for nothing less than control of the emirate, and an impasse was reached. Even before the fight began, dissension spread through some of Abd al-Rahman's lines. Specifically, the Yemeni Arabs were unhappy that the prince was mounted on a fine Spanish steed and that his mettle was untried in battle. The Yemenis observed significantly that such a fine horse would provide an excellent mount to escape from battle. Being the ever-wary politician, Abd al-Rahman acted quickly to regain Yemeni support, and rode to a Yemeni chief who was mounted on a mule named "Lightning". Abd al-Rahman averred that his horse proved difficult to ride and was wont to buck him out of the saddle. He offered to exchange his horse for the mule, a deal to which the surprised chief readily agreed. The swap quelled the simmering Yemeni rebellion. Soon both armies were in their lines on the same bank of the Guadalquivir. Abd al-Rahman had no banner, and so one was improvised by unwinding a green turban and binding it round the head of a spear. Subsequently, the turban and the spear became the banner and symbol of the Andalusian Umayyads. Abd al-Rahman led the charge toward al-Fihri's army. Al-Sumayl in turn advanced his cavalry out to meet the Umayyad threat. After a long and difficult fight "Abd ar-Rahman obtained a most complete victory, and the field was strewn with the bodies of the enemy.". Both al-Fihri and al-Sumayl managed to escape the field (probably) with parts of the army too. Abd al-Rahman triumphantly marched into the capital, Córdoba. Danger was not far behind, as al-Fihri planned a counter attack. He reorganized his forces and set out for the capital Abd al-Rahman had usurped from him. Again Abd al-Rahman met al-Fihri with his army; this time negotiations were successful, although the terms were somewhat changed. In exchange for al-Fihri's life and wealth, he would be a prisoner and not allowed to leave the city limits of Córdoba. Al-Fihri would have to report once a day to Abd al-Rahman, as well as turn over some of his sons and daughters as hostages. For a while al-Fihri met the obligations of the one-sided truce, but he still had many people loyal to him--people who would have liked to see him back in power. Al-Fihri eventually did make another bid for power. He quit Córdoba and quickly started gathering supporters. While at large, al-Fihri managed to gather an army allegedly numbering 20,000. It is doubtful, however, that his troops were "regular" soldiers, but rather a hodge-podge of men from various parts of al-Andalus. Abd al-Rahman's appointed governor in Sevilla took up the chase, and after a series of small fights, managed to defeat al-Fihri's army. Al-Fihri himself managed to escape to the former Visigoth capital of Toledo in central al-Andalus; once there, he was promptly killed. Al-Fihri's head was sent to Córdoba, where Abd al-Rahman had it nailed to a bridge. With this act, Abd al-Rahman proclaimed himself the emir of al-Andalus. However, in order to take over southern Iberia, al-Fihri's general, al-Sumayl, had to be dealt with, and he was garroted in Córdoba's jail. Still, most of central and northern al-Andalus (Toledo, Zaragoza, Barcelona, etc.) was out of his rule, with large swathes remaining in the hands of Yusuf ibn 'Abd al-Rahman al-Fihri's supporters until 779 (submission of Zaragoza). Rule It is unclear whether Abd al-Rahman proclaimed himself caliph. There are documents in the archives of Cordoba that state that this was his first act upon entering the city. However, historically he is recorded as Emir and not Caliph. Abd al-Rahman's 7th descendant, Abd al-Rahman III, would, however, take up the title of caliph. In the meantime, a call went out through the Muslim world that al-Andalus was a safe haven for friends of the house of Umayya, if not for Abd al-Rahman's scattered family that managed to evade the Abbasids. Abd al-Rahman probably was quite happy to see his call answered by waves of Umayyad faithful and family. He was finally reacquainted with his son Sulayman, whom he last saw weeping on the banks of the Euphrates with his sisters. Abd al-Rahman's sisters were unable to make the long voyage to al-Andalus. Abd al-Rahman placed his family members in high offices across the land, as he felt he could trust them more than non-family. The Umayyad family would again grow large and prosperous over successive generations. One of these kinsmen, Abd al-Malik ibn Umar ibn Marwan, persuaded Abd al-Rahman in 757 to drop the name of the Abbasid caliph from the Friday prayers (a traditional recognition of sovereignty in medieval Islam), and became one of his top generals and his governor in Seville. By 763 Abd ar-Rahman had to get back to the business of war. Al-Andalus had been invaded by an Abbasid army. Far away in Baghdad, the current Abbasid caliph, al-Mansur, had long been planning to depose the Umayyad who dared to call himself emir of al-Andalus. Al-Mansur installed al-Ala ibn-Mugith as governor of Africa (whose title gave him dominion over the province of al-Andalus). It was al-Ala who headed the Abbasid army that landed in al-Andalus, possibly near Beja (in modern-day Portugal). Much of the surrounding area of Beja capitulated to al-Ala, and in fact rallied under the Abbasid banners against Abd al-Rahman. Abd al-Rahman had to act quickly. The Abbasid contingent was vastly superior in size, said to have numbered 7,000 men. The emir quickly made for the redoubt of Carmona with his army. The Abbasid army was fast on their heels, and laid siege to Carmona for approximately two months. Abd al-Rahman must have sensed that time was against him as food and water became scarce, and his troops morale likely came into question. Finally Abd al-Rahman gathered his men as he was "resolved on an audacious sally". Abd al-Rahman hand-picked 700 fighters from his army and led them to Carmona's main gate. There, he started a great fire and threw his scabbard into the flames. Abd al-Rahman told his men that time had come to go down fighting rather than die of hunger. The gate lifted and Abd al-Rahman's men fell upon the unsuspecting Abbasids, thoroughly routing them. Most of the Abbasid army was killed. The heads of the main Abbasid leaders were cut off, preserved in salt, identifying tags pinned to their ears, and then bundled together in a gruesome package and sent to the Abbasid caliph, who was on pilgrimage at Mecca. Upon receiving the evidence of al-Ala's defeat in al-Andalus, al-Mansur is said to have gasped, "God be praised for placing a sea between us!" Al-Mansur hated, and yet apparently respected Abd al-Rahman to such a degree that he dubbed him the "Hawk of Quraysh" (the Umayyads were from a branch of the Quraysh tribe). Despite such a tremendous victory, Abd al-Rahman had to continuously put down rebellions in al-Andalus. Various Arab and Berber tribes fought each other for varying degrees of power, some cities tried to break away and form their own state, and even members of Abd al-Rahman's family tried to wrest power from him. During a large revolt, dissidents marched on Córdoba itself; However, Abd al-Rahman always managed to stay one step ahead, and crushed all opposition; as he always dealt severely with dissidents in al-Andalus. Problems in the Upper March Zaragoza proved to be a most difficult city to reign over for not only Abd ar-Rahman, but his successors as well. In the year 777–778, several notable men including Sulayman ibn Yokdan al-Arabi al-Kelbi, the self-appointed governor of Zaragoza, met with delegates of the leader of the Franks, Charlemagne. "[Charlemagne's] army was enlisted to help the Muslim governors of Barcelona and Zaragoza against the Umayyad [emir] in Cordoba...." Essentially Charlemagne was being hired as a mercenary, even though he likely had other plans of acquiring the area for his own empire. After Charlemagne's columns arrived at the gates of Zaragoza, Sulayman got cold feet and refused to let the Franks into the city, after his subordinate, al-Husayn ibn Yahiya, had successfully defeated and captured Abd al-Rahman's most trusted general, Thalaba Ibn Ubayd. It is possible that he realized that Charlemagne would want to usurp power from him. After capturing Sulayman, Charlemagne's force eventually headed back to France via a narrow pass in the Pyrenees, where his rearguard was wiped out by Basque and Gascon rebels (this disaster inspired the epic Chanson de Roland). Charlemagne was also attacked by Sulayman's relatives, who had freed Sulayman. Now Abd al-Rahman could deal with Sulayman and the city of Zaragoza without having to fight a massive Christian army. In 779 Abd al-Rahman offered Husayn, one of Sulayman's allies, the job of Zaragoza's governorship. The temptation was too much for al-Husayn, who murdered his colleague Sulayman. As promised, al-Husayn was awarded Zaragoza with the expectation that he would always be a subordinate of Córdoba. However, within two years al-Husayn broke off relations with Abd al-Rahman and announced that Zaragoza would be an independent city-state. Once again Abd al-Rahman had to be concerned with developments in the Upper March. He was intent on keeping this important northern border city within the Umayyad fold. By 783 Abd al-Rahman's army advanced on Zaragoza. It appeared as though Abd al-Rahman wanted to make clear to this troublesome city that independence was out of the question. Included in the arsenal of Abd al-Rahman's army were thirty-six siege engines. Zaragoza's famous white granite defensive walls were breached under a torrent of ordnance from the Umayyad lines. Abd al-Rahman's warriors spilled into the city's streets, quickly thwarting al-Husayn's desires for independence. Legacy and death Social dynamics and construction works After the aforementioned period of conflict, Abd al-Rahman continued in his improvement of al-Andalus' infrastructure. He ensured roadways were begun, aqueducts were constructed or improved, and that a new mosque was well funded in his capital at Córdoba. Construction on what would in time become the world-famous Great Mosque of Córdoba was started circa the year 786. Abd al-Rahman knew that one of his sons would one day inherit the rule of al-Andalus, but that it was a land torn by strife. In order to successfully rule in such a situation, Abd al-Rahman needed to create a reliable civil service and organize a standing army. He felt that he could not always rely on the local populace in providing a loyal army; and therefore bought a massive standing army consisting mainly of Berbers from North Africa as well as slaves from other areas. The total number of soldiers under his command was nearly 40,000. As was common during the years of Islamic expansion from Arabia, religious tolerance was practiced. Abd al-Rahman continued to allow Jews and Christians and other monotheistic religions to retain and practice their faiths, in exchange for the jizya. Possibly because of tribute taxes, "the bulk of the country's population must have become Muslim". However, other scholars have argued that though 80% of al-Andalus converted to Islam, it did not truly occur until near the 10th century. Christians more often converted to Islam than Jews although there were converted Jews among the new followers of Islam. There was a great deal of freedom of interaction among the groups: for example, Sarah, the granddaughter of the Visigoth king Wittiza, married a Muslim man and bore two sons who were later counted among the ranks of the highest Arab nobility. Abd al-Rahman I was able to forge a new Umayyad dynasty by standing successfully against Charlemagne, the Abbasids, the Berbers, and other Muslim Spaniards. His legacy started a new chapter for the Umayyad Dynasty ensuring their survival and culminating in the new Umayyad Caliphate of Cordoba by his descendants. Death Abd al-Rahman died c. 788 in Córdoba, and was supposedly buried under the site of the Mezquita. Abd al-Rahman's alleged favorite son was his choice for successor, and would later be known as Hisham I. Abd al-Rahman's progeny would continue to rule al-Andalus in the name of the house of Umayya for several generations, with the zenith of their power coming during the reign of Abd al-Rahman III. Family Abd al-Rahman was the son of Mu'awiya, son of Hisham, son of Abd al-Malik, according to Abd el-Wahid Merrakechi when reciting his ancestry. Abd al-Rahman's mother was a member of the Nafza Berbers with whom he found refuge after the murder of his family in 750. Abd al-Rahman married a Spanish Sephardi woman named Hulal. She is said to have been very beautiful and was the mother of Hisham. Abd al-Rahman was the father of several sons, but the identity of their mother(s) is not clear: Sulayman (745–800), Governor of Toledo. Exiled after he refused to accept his brother Hisham's rule. Returned to challenge his nephew in 796, captured and executed in 800. Omar (died before 758), captured in battle and executed by Fruela I of Asturias. Hisham I (757–17 Apr 796), Emir of Cordoba. Abdallah Legends In his lifetime, Abd al-Rahman was known as al Dakhil ("the Entrant"), but he was also known as Saqr Quraish ("The Falcon of the Quraish"), bestowed on him by one of his greatest enemies, the Abbasid caliph al-Mansur. According to the chroniclers, al-Mansur once asked his courtiers who deserved the exalted title of "Falcon of the Quraysh" (Saqr Quraish'', foremost of the Quraysh). The obsequious courtiers naturally replied "You, O Commander of the Faithful!", but the Caliph denied this. Then they suggested Mu'awiya (founder of the Umayyad Caliphate), but the Caliph again denied it. Then they suggested Abd al-Malik ibn Marwan (one of the greatest of the Umayyad caliphs), but again no. They asked who it was, and al-Mansur replied: See also Timeline of the Muslim presence in the Iberian peninsula Abbasid Revolution al-Andalus Caliphate of Córdoba Abd al-Malik ibn Umar Sara al-Qutiyya Further reading Maria Rosa Menocal, The Ornament of the World: How Muslims, Jews and Christians Created a Culture of Tolerance in Medieval Spain (2002) Andrea Pancini, L'immigrante (2016) References External links Emirs of Córdoba 731 births 788 deaths 8th-century Arab people 8th-century monarchs in Europe

Aberdare ( ; ) is a town in the Cynon Valley area of Rhondda Cynon Taf, Wales, at the confluence of the Rivers Dare (Dâr) and Cynon. Aberdare has a population of 39,550 (mid-2017 estimate). Aberdare is south-west of Merthyr Tydfil, north-west of Cardiff and east-north-east of Swansea. During the 19th century it became a thriving industrial settlement, which was also notable for the vitality of its cultural life and as an important publishing centre. Etymology The name Aberdare means "mouth/confluence of the river Dare", as the town is located where the Dare river () meets the Cynon (). While the town's Welsh spelling uses formal conventions, the English spelling of the name reflects the town's pronunciation in the local Gwenhwyseg dialect of South East Wales. Dâr is an archaic Welsh word for oaks (derwen is the singulative), and the valley was noted for its large and fine oaks as late as the 19th century. In ancient times, the river may have been associated with Daron, an ancient Celtic goddess of oak. As such, the town would share an etymology with Aberdaron and the Daron river. As with many Welsh toponyms, it is likely that the locality was known by this name long before the development of the town. History Early history There are several cairns and the remains of a circular British encampment on the mountain between Aberdare and Merthyr. This may have led to the mountain itself being named Bryn-y-Beddau (hill of graves) although other local traditions associate the name with the Battle of Hirwaun Wrgant. Middle Ages Aberdare lies within the commote (cwmwd) of Meisgyn, in the cantref of Penychen. The area is traditionally given as the scene of the battle of Hirwaun Wrgant, where the allied forces of the Norman Robert Fitzhamon and Iestyn ap Gwrgant, the last Welsh prince of Glamorgan, defeated Rhys ap Tewdwr, prince of Dyfed. The battle is thought to have started at Aberdare, with the areas now known as Upper and Lower Gadlys (The battle Court(s)), traditionally given as each armies' headquarters. The settlement of Aberdare dates from at least this period, with the first known reference being in a monastic chapter of 1203 concerning grazing right on Hirwaun Common. It was originally a small village in an agricultural district, centred around the Church of St John the Baptist, said to date from at least 1189. By the middle of the 15th century, Aberdare contained a water mill in addition to a number of thatched cottages, of which no evidence remains. Industrial Aberdare Aberdare grew rapidly in the early 19th century through two major industries: first iron, then coal. A branch of the Glamorganshire Canal (1811) was opened to transport these products; then the railway became the main means of transport to the South Wales coast. From the 1870s onwards, the economy of the town was dominated by the coal mining industry, with only a small tinplate works. There were also several brickworks and breweries. During the latter half of the 19th century, considerable improvements were made to the town, which became a pleasant place to live, despite the nearby collieries. A postgraduate theological college opened in connection with the Church of England in 1892, but in 1907 it moved to Llandaff. With the ecclesiastical parishes of St Fagan's (Trecynon) and Aberaman carved out of the ancient parish, Aberdare had 12 Anglican churches and one Catholic church, built in 1866 in Monk Street near the site of a cell attached to Penrhys monastery; and at one time there were over 50 Nonconformist chapels (including those in surrounding settlements such as Cwmaman and Llwydcoed). The services in the majority of the chapels were in Welsh. Most of these chapels have now closed, with many converted to other uses. The former urban district included what were once the separate villages of Aberaman, Abernant, Cwmaman, Cwmbach, Cwmdare, Llwydcoed, Penywaun and Trecynon. Population growth In 1801, the population of the parish of Aberdare was just 1,486, but the early 19th century saw rapid industrial growth, first through the ironworks, and later through the iron and steam coal industries. By the 1840s the parish population was increasing by 1,000 people every year, almost exclusively migrant workers from west Wales, which was suffering from an agricultural depression. This growth was increasingly concentrated in the previously agricultural areas of Blaengwawr and Cefnpennar to the south of the town. The population of the Aberdare District (centred on the town) was 9,322 in 1841, 18,774 in 1851, and 37,487 in 1861. Despite a small decline in the 1870s, population levels continued to increase, with the first decade of the 20th century seeing a notably sharp increase, largely as a result of the steam coal trade, reaching 53,779 in 1911. The population has since declined owing to the loss of most of the heavy industry. The Aberdare population at the 2001 census was 31,705 (ranked 13th largest in Wales). By 2011 it was 29,748, though the figure includes the surrounding populations of Aberaman, Abercwmboi, Cwmbach and Llwydcoed. Language Welsh was the prominent language until the mid 20th century and Aberdare was an important centre of Welsh language publishing. A large proportion of the early migrant population were Welsh speaking, and in 1851 only ten per cent of the population had been born outside of Wales. In his controversial evidence to the 1847 Inquiry into the State of Education in Wales (the report of which is known in Wales as the Brad y Llyfrau Gleision, Treason of the Blue Books), the Anglican vicar of Aberdare, John Griffith, stated that the English language was "generally understood" and referred to the arrival of people from anglicised areas such as Radnorshire and south Pembrokeshire. Griffith also made allegations about the Welsh-speaking population and what he considered to be the degraded character of the women of Aberdare, alleging sexual promiscuity was an accepted social convention, that drunkenness and improvidence amongst the miners was common and attacking what he saw as exaggerated emotion in the religious practices of the Nonconformists. This evidence helped inform the findings of the report which would go on to stigmatise Welsh people as "ignorant", "lazy" and "immoral" and found the reason for this was the continued use of the Welsh language, which it described as "evil". The controversial reports allowed the local nonconformist minister Thomas Price of Calfaria to arrange public meetings, from which he would emerge as a leading critic of the vicar's evidence and, by implication, a defender of both the Welsh language and the morality of the local population, It is still contended that Griffiths was made vicar of Merthyr in the neighbouring valley to escape local anger, even though it was over ten years before he left Aberdare. The reports and subsequent defence would maintain the perceptions of Aberdare, the Cynon Valley and even the wider area as proudly nonconformist and defiantly Welsh speaking throughout its industrialised history. By 1901, the census recorded that 71.5% of the population of Aberdare Urban District spoke Welsh, but this fell to 65.2% in 1911. The 1911 data shows that Welsh was more widely spoken among the older generation compared to the young, and amongst women compared to men. A shift in language was expedited with the loss of men during the First World War and the resulting economic turmoil. English gradually began to replace Welsh as the community language, as shown by the decline of the Welsh language press in the town. This pattern continued after the Second World War despite the advent of Welsh medium education. Ysgol Gymraeg Aberdâr, the Welsh-medium primary school, was established in the 1950s with Idwal Rees as head teacher. According to the 2011 Census, 11.6% of Aberdare residents aged three years and over could speak Welsh, with 24.8% of 3- to 15-year-olds stating that they could speak it. Industry Iron industry Ironworks were established at Llwydcoed and Abernant in 1799 and 1800 respectively, followed by others at Gadlys and Aberaman in 1827 and 1847. The iron industry began to expand in a significant way around 1818 when the Crawshay family of Merthyr purchased the Hirwaun ironworks and placed them under independent management. In the following year, Rowland Fothergill took over the ironworks at Abernant and a few years later did the same at Llwydcoed. Both concerns later fell into the hands of his nephew Richard Fothergill. The Gadlys Ironworks was established in 1827 by Matthew Wayne, who had previously managed the Cyfarthfa ironworks at Merthyr. The Gadlys works, now considered an important archaeological site, originally comprised four blast furnaces, inner forges, rowing mills and puddling furnaces. The development of these works provided impetus to the growth of Aberdare as a nucleated town. The iron industry was gradually superseded by coal and all the five iron works had closed by 1875, as the local supply of iron ore was inadequate to meet the ever-increasing demand created by the invention of steel, and as a result the importing of ore proved more profitable. Coal industry The iron industry had a relatively small impact upon the economy of Aberdare and in 1831 only 1.2% of the population was employed in manufacturing, as opposed to 19.8% in neighbouring Merthyr Tydfil. In the early years of Aberdare's development, most of the coal worked in the parish was coking coal, and was consumed locally, chiefly in the ironworks. Although the Gadlys works was small in comparison with the other ironworks it became significant as the Waynes also became involved in the production of sale coal. In 1836, this activity led to the exploitation of the "Four-foot Seam" of high-calorific value steam coal began, and pits were sunk in rapid succession. In 1840, Thomas Powell sank a pit at Cwmbach, and during the next few years he opened another four pits. In the next few years, other local entrepreneurs now became involved in the expansion of the coal trade, including David Williams at Ynysgynon and David Davis at Blaengwawr, as well as the latter's son David Davis, Maesyffynnon. They were joined by newcomers such as Crawshay Bailey at Aberaman and, in due course, George Elliot in the lower part of the valley. This coal was valuable for steam railways and steam ships, and an export trade began, via the Taff Vale Railway and the port of Cardiff. The population of the parish rose from 6,471 in 1841 to 14,999 in 1851 and 32,299 in 1861 and John Davies described it as "the most dynamic place in Wales". In 1851, the Admiralty decided to use Welsh steam coal in ships of the Royal Navy, and this decision boosted the reputation of Aberdare's product and launched a huge international export market. Coal mined in Aberdare parish rose from in 1844 to in 1850, and the coal trade, which after 1875 was the chief support of the town, soon reached huge dimensions. The growth of the coal trade inevitably led to a number of industrial disputes, some of which were local and others which affected the wider coalfield. Trade unionism began to appear in the Aberdare Valley at intervals from the 1830s onwards but the first significant manifestation occurred during the Aberdare Strike of 1857–8. The dispute was initiated by the depression in trade which followed the Crimean War and saw the local coal owners successfully impose a reduction in wages. The dispute did, however, witness an early manifestation of mass trade unionism amongst the miners of the valley and although unsuccessful the dispute saw the emergence of a stronger sense of solidarity amongst the miners. Steam coal was subsequently found in the Rhondda and further west, but many of the great companies of the Welsh coal industry's Gilded Age started operation in Aberdare and the lower Cynon Valley, including those of Samuel Thomas, David Davies and Sons, Nixon's Navigation and Powell Duffryn. During the early years of the twentieth century, the Aberdare valley became the focus of increased militancy among the mining workforce and an unofficial strike by 11,000 miners in the district from 20 October 1910 unyil 2 February 1911 attracted much attention at the time, although it was ultimately overshadowed by the Cambrian dispute in the neighbouring Rhondda valley which became synonymous with the so-called Tonypandy Riots. In common with the rest of the South Wales coalfield, Aberdare's coal industry commenced a long decline after World War I, and the last two deep mines still in operation in the 1960s were the small Aberaman and Fforchaman collieries, which closed in 1962 and 1965 respectively. On 11 May 1919, an extensive fire broke out on Cardiff Street, Aberdare. With the decline of both iron and coal, Aberdare has become reliant on commercial businesses as a major source of employment. Its industries include cable manufacture, smokeless fuels, and tourism. Government As a small village in the upland valleys of Glamorgan, Aberdare did not play any significant part in political life until its development as an industrial settlement. It was part of the lordship of Miskin, and the ancient office of High Constable continued in ceremonial form until relatively recent times. Parliamentary elections In 1832, Aberdare was removed from the Glamorgan county constituency and became part of the parliamentary borough (constituency) of Merthyr Tydfil. For much of the nineteenth century, the representation was initially controlled by the ironmasters of Merthyr, notably the Guest family. From 1852 until 1868 the seat was held by Henry Austen Bruce whose main industrial interests lay in the Aberdare valley. Bruce was a Liberal but was viewed with suspicion by the more radical faction which became increasingly influential within Welsh Liberalism in the 1860s. The radicals supported such policies as the disestablishment of the Church of England and were closely allied to the Liberation Society. 1868 general election Nonconformist ministers played a prominent role in this new politics and, at Aberdare, they found an effective spokesman in the Rev Thomas Price minister of Calfaria, Aberdare. Following the granting of a second parliamentary seat to the borough of Merthyr Tydfil in 1867, the Liberals of Aberdare sought to ensure that a candidate from their part of the constituency was returned alongside the sitting member, Henry Austen Bruce. Their choice fell upon Richard Fothergill, owner of the ironworks at Abernant, who was enthusiastically supported by the Rev Thomas Price. Shortly before the election, however, Henry Richard intervened as a radical Liberal candidate, invited by the radicals of Merthyr. To many people's surprise, Price was lukewarm about his candidature and continued to support Fothergill. Ultimately, Henry Richard won a celebrated victory with Fothergill in second place and Bruce losing his seat. Richard thus became one of the-first radical MPs from Wales. 1874–1914 At the 1874 General Election, both Richard and Fothergill were again returned, although the former was criticised for his apparent lack of sympathy towards the miners during the industrial disputes of the early 1870s. This led to the emergence of Thomas Halliday as the first labour or working-class candidate to contest a Welsh constituency. Although he polled well, Halliday fell short of being elected. For the remainder of the nineteenth century, the constituency was represented by industrialists, most notably David Alfred Thomas. In 1900, however, Thomas was joined by Keir Hardie, the ILP candidate, who became the first labour representative to be returned for a Welsh constituency independent of the Liberal Party. 20th century The Aberdare constituency came into being at the 1918 election. The first representative was Charles Butt Stanton, who had been elected at a by-election following Hardie's death in 1915. However, in 1922, Stanton was defeated by a Labour candidate, and Labour has held the seat ever since. The only significant challenge came from Plaid Cymru at the 1970 and February 1974 General Elections, but these performances have not since been repeated. From 1984 until 2019 the parliamentary seat, now known as Cynon Valley, was held by Ann Clwyd of Labour. Local government Aberdare was an ancient parish within Glamorgan. Until the mid-19th century the local government of Aberdare and its locality remained in the hands of traditional structures such as the parish vestry and the High Constable, who was chosen annually. However, with the rapid industrial development of the parish, these traditional bodies could not cope with the realities of an urbanised, industrial community which had developed without any planning or facilities. During the early decades of the 19th century the ironmasters gradually imposed their influence over local affairs, and this remained the case following the formation of the Merthyr Board of Guardians in 1836. During the 1850s and early 1860s, however, as coal displaced iron as the main industry in the valley, the ironmasters were displaced as the dominant group in local government and administration by an alliance between mostly indigenous coal owners, shopkeepers and tradesmen, professional men and dissenting ministers. A central figure in this development was the Rev Thomas Price. The growth of this alliance was rooted in the reaction to the 1847 Education Reports and the subsequent efforts to establish a British School at Aberdare. In the 1840s there were no adequate sanitary facilities or water supply, and mortality rates were high. Outbreaks of cholera and typhus were commonplace. Against this background, Thomas Webster Rammell prepared a report for the General Board of Health on the sanitary condition of the parish, which recommended that a local board of health be established. The whole parish of Aberdare was formally declared a local board district on 31 July 1854, to be governed by the Aberdare Local Board of Health. Its first chairman was Richard Fothergill and the members included David Davis, Blaengwawr, David Williams (Alaw Goch), Rees Hopkin Rhys and the Rev. Thomas Price. It was followed by the Aberdare School Board in 1871. By 1889, the Local Board of Health had initiated a number of developments: these included the purchase of local reservoirs from the Aberdare Waterworks Company for £97,000, a sewerage scheme costing £35,000, as well as the opening of Aberdare Public Park and a local fever hospital. The lack of a Free Library, however, remained a concern. Later, the formation of the Glamorgan County Council (upon which Aberdare had five elected members) in 1889, followed by the Aberdare Urban District Council, which replaced the Local Board in 1894, transformed the local politics of the Aberdare valley. At the 1889 Glamorgan County Council Elections most of the elected representatives were coalowners and industrialists, and the only exception in the earlier period was the miners' agent David Morgan (Dai o'r Nant), elected in 1892 as a labour representative. From the early 1900s, however, Labour candidates began to gain ground and dominated local government from the 1920s onwards. The same pattern was seen on the Aberdare UDC. Aberdare Urban District was abolished in 1974 under the Local Government Act 1972. The area became part of the borough of Cynon Valley within the new county of Mid Glamorgan. The area of the former urban district was made a community, later being subdivided in 1982 into five communities: Aberaman, Cwmbach, Llwydcoed, Penywaun, and a smaller Aberdare community. The Aberdare community was further divided in 2017 into two communities called Aberdare East and Aberdare West. Aberdare East includes Aberdare town centre and the village of Abernant. Aberdare West includes Cwmdare, Cwm Sian and Trecynon. No community council exists for either of the Aberdare communities. Cynon Valley Borough Council and Mid Glamorgan County Council were both abolished in 1996, since when Aberdare has been governed by Rhondda Cynon Taf County Borough Council. The town lies mainly in the Aberdare East ward, represented by two county councillors. Nearby Cwmdare, Llwydcoed and Trecynon are represented by the Aberdare West/Llwydcoed ward. Both wards have been represented by the Labour Party since 2012. Culture Aberdare, during its boom years, was considered a centre of Welsh culture: it hosted the first National Eisteddfod in 1861, with which David Williams (Alaw Goch) was closely associated. The town erected a monument in the local park to commemorate the occasion. A number of local eisteddfodau had long been held in the locality, associated with figures such as William Williams (Carw Coch) The Eisteddfod was again held in Aberdare in 1885, and also in 1956 at Aberdare Park, where the Gorsedd standing stones still exist. At the last National Eisteddfod held in Aberdare in 1956 Mathonwy Hughes won the chair. From the mid 19th century, Aberdare was an important publishing centre where a large number of books and journals were produced, the majority of which were in the Welsh language. A newspaper entitled Y Gwladgarwr (the Patriot) was published at Aberdare from 1856 until 1882 and was circulated widely throughout the South Wales valleys. From 1875 a more successful newspaper, Tarian y Gweithiwr (the Workman's Shield) was published at Aberdare by John Mills. Y Darian, as it was known, strongly supported the trade union movements among the miners and ironworkers of the valleys. The miners' leader, William Abraham, derived support from the newspaper, which was also aligned with radical nonconformist liberalism. The rise of the political labour movement and the subsequent decline of the Welsh language in the valleys, ultimately led to its decline and closure in 1934. The Coliseum Theatre is Aberdare's main arts venue, containing a 600-seat auditorium and cinema. It is situated in nearby Trecynon and was built in 1938 using miners' subscriptions. The Second World War poet Alun Lewis was born near Aberdare in the village of Cwmaman; there is a plaque commemorating him, including a quotation from his poem The Mountain over Aberdare. The founding members of the rock band Stereophonics originated from Cwmaman. It is also the hometown of guitarist Mark Parry of Vancouver rock band The Manvils. Famed anarchist-punk band Crass played their last live show for striking miners in Aberdare during the UK miners' strike. Griffith Rhys Jones − or Caradog as he was commonly known − was the conductor of the famous 'Côr Mawr' ("great choir") of some 460 voices (the South Wales Choral Union), which twice won first prize at Crystal Palace choral competitions in London in the 1870s. He is depicted in the town's most prominent statue by sculptor Goscombe John, unveiled on Victoria Square in 1920. Aberdare was culturally twinned with the German town of Ravensburg. Religion Anglican Church The original parish church of St John the Baptist was originally built in 1189. Some of its original architecture is still intact. With the development of Aberdare as an industrial centre in the nineteenth century it became increasingly apparent that the ancient church was far too small to service the perceived spiritual needs of an urban community, particularly in view of the rapid growth of nonconformity from the 1830s onwards. Eventually, John Griffith, the rector of Aberdare, undertook to raise funds to build a new church, leading to the rapid construction of St Elvan's Church in the town centre between 1851 and 1852. This Church in Wales church still stands the heart of the parish of Aberdare and has had extensive work since it was built. The church has a modern electrical, two-manual and pedal board pipe organ, that is still used in services. John Griffith, vicar of Aberdare, who built St Elvan's, transformed the role of the Anglican church in the valley by building a number of other churches, including St Fagan's, Trecynon. Other churches in the parish are St Luke's (Cwmdare), St James's (Llwydcoed) and St Matthew's (1891) (Abernant). In the parish of Aberaman and Cwmaman is St Margaret's Church, with a beautiful old pipe organ with two manuals and a pedal board. Also in this parish is St Joseph's Church, Cwmaman. St Joseph's has recently undergone much recreational work, almost converting the church into a community centre, surrounded by a beautiful floral garden and leading to the Cwmaman Sculpture Trail. However, regular church services still take place. Here, there is a two-manual and pedal board electric organ, with speakers at the front and sides of the church. In 1910 there were 34 Anglican churches in the Urban District of Aberdare. A survey of the attendance at places of worship on a particular Sunday in that year recorded that 17.8% of worshippers attended church services, with the remainder attending nonconformist chapels. Nonconformity The Aberdare Valley was a stronghold of Nonconformity from the mid-nineteenth century until the inter-war years. In the aftermath of the 1847 Education Reports nonconformists became increasingly active in the political and educational life of Wales and in few places was this as prevalent as at Aberdare. The leading figure was Thomas Price, minister of Calfaria, Aberdare. Aberdare was a major centre of the 1904–05 Religious Revival, which had begun at Loughor near Swansea. The revival aroused alarm among ministers for the revolutionary, even anarchistic, impact it had upon chapel congregations and denominational organisation. In particular, it was seen as drawing attention away from pulpit preaching and the role of the minister. The local newspaper, the Aberdare Leader, regarded the revival with suspicion from the outset, objecting to the 'abnormal heat' which it engendered. Trecynon was particularly affected by the revival, and the meetings held there were said to have aroused more emotion and excitement than the more restrained meetings in Aberdare itself. The impact of the revival was significant in the short term, but in the longer term was fairly transient. Once the immediate impact of the revival had faded, it was clear from the early 20th century that there was a gradual decline in the influence of the chapels. This can be explained by several factors, including the rise of socialism and the process of linguistic change which saw the younger generation increasingly turn to the English language. There were also theological controversies such as that over the New Theology propounded by R.J. Campbell. Of the many chapels, few are still used for their original purpose and a number have closed since the turn of the millennium. Many have been converted for housing or other purposes (including one at Robertstown which has become a mosque), and others demolished. Among the notable chapels were Calfaria, Aberdare and Seion, Cwmaman (Baptist); Saron, Aberaman and Siloa, Aberdare (Independent); and Bethania, Aberdare (Calvinistic Methodist). Independents The earliest Welsh Independent, or Congregationalist chapel in the Aberdare area was Ebenezer, Trecynon, although meetings had been held from the late 18th century in dwelling houses in the locality, for example at Hirwaun. During the 19th century, the Independents showed the biggest increases in terms of places of worship: from two in 1837 to twenty-five (four of them being English causes), in 1897. By 1910 there were 35 Independent chapels, with a total membership of 8,612. Siloa Chapel was the largest of the Independent chapels in Aberdare and is one of the few that remain open today, having been 're-established' as a Welsh language chapel. The Independent ministers of nineteenth-century Aberdare included some powerful personalities, but none had the kind of wider social authority which Thomas Price enjoyed amongst the Baptists. Of the other Independent chapels in the valley, Saron, in Davis Street, Aberaman, was used for regular services by a small group of members until 2011. For many years, these were held in a small side-room, and not the chapel itself. The chapel has a large vestry comprising rows of two-way-facing wooden benches and a stage, with a side entrance onto Beddoe Street and back entrance to Lewis Street. Although the building is not in good repair, the interior, including pulpit and balcony seating area (back and sides), was in good order but the chapel eventually closed due to the very small number of members remaining. In February 1999, Saron became a Grade II Listed Building. Baptists The Baptists were the most influential of the nonconformist denominations in Aberdare and their development was led by the Rev. Thomas Price who came to Aberdare in the early 1840s as minister of Calfaria Chapel. In 1837 the Baptists had three chapels, but in 1897 there were twenty, seventeen of them being Welsh. By 1910 the number of chapels had increased to 30, with a total membership of 7,422. Most of these Baptist chapels were established under the influence of Thomas Price who encouraged members to establish branch chapels to attract migrants who flocked to the town and locality from rural Wales. The chapels came together for regular gatherings, including baptismal services which were held in the River Cynon As a result, Price exerted an influence in the religious life of the locality which was far greater than that of any other minister. Calvinistic Methodists By 1910 there were 24 Calvinistic Methodist chapels in the Aberdare Urban District with a total membership of 4,879. The most prominent of these was Bethania, Aberdare, once the largest chapel in Aberdare. Derelict for many years, it was demolished in 2015. The Methodists were numerically powerful and while some of their ministers such as William James of Bethania served on the Aberdare School Board and other public bodies, their constitution militated against the sort of active political action which came more naturally to the Baptists and Independents. Other denominations In 1878 Mother Shepherd, a native Welsh speaker, was sent to Aberdare by the Salvation Army at the start of a period of growth for their mission. After five years she had created seven new stations before she was recalled to London. Shepherd would return to Aberdare working for the community. In 1930 she was given a public funeral. The Wesleyan Methodists had 14 places of worship by 1910. There was also a significant Unitarian tradition in the valley and three places of worship by 1910. Highland Place Unitarian Church celebrated its 150th anniversary in 2010, with a number of lectures on its history and the history of Unitarianism in Wales taking place there. The church has a two-manual pipe organ with pedal board that is used to accompany all services. The current organist is Grace Jones, the sister of the former organist Jacob Jones. The connected schoolroom is used for post-service meetings and socialising. Judaism Seymour Street was once home to a synagogue which opened its doors in the late 1800s but closed in 1957. The site now has a blue plaque. Education The state of education in the parish was a cause for concern during the early industrial period as is illustrated by the reaction to the 1847 Education Reports. Initially, there was an outcry, led by the Rev Thomas Price against the comments made by the vicar of Aberdare in his submission to the commissioners. However, on closer reflection, the reports related the deficiencies of educational provision, not only in Aberdare itself but also in the communities of the valleys generally. In so doing they not only criticised the ironmasters for their failure to provide schools for workers' children but also the nonconformists for not establishing British Schools. At the ten schools in Aberdare there was accommodation for only 1,317 children, a small proportion of the population. Largely as a result of these criticisms, the main nonconformist denominations worked together to establish a British School, known locally as Ysgol y Comin, which was opened in 1848, accommodating 200 pupils. Funds were raised which largely cleared the debts and the opening of the school was marked by a public meeting addressed by Price and David Williams (Alaw Goch). Much energy was expended during this period on conflicts between Anglicans and nonconformists over education. The establishment of the Aberdare School Board in 1871 brought about an extension of educational provision but also intensified religious rivalries. School Board elections were invariably fought on religious grounds. Despite these tensions the Board took over a number of existing schools and established new ones. By 1889, fourteen schools were operated by the Board but truancy and lack of attendance remained a problem, as in many industrial districts. In common with other public bodies at the time (see 'Local Government' above), membership of the School Board was dominated by coal owners and colliery officials, nonconformist ministers, professional men and tradesmen. Only occasionally was an Anglican clergyman elected and, with the exception of David Morgan (Dai o'r Nant), no working class candidates were elected for more than one term. Colleges Coleg y Cymoedd Secondary schools Aberdare Community School St. John the Baptist School (Aberdare) Ysgol Gyfun Rhydywaun Transport The town is served by Aberdare railway station and Aberdare bus station, opposite each other in the town centre. The town has also been subject to an extensive redevelopment scheme during 2012–13. Sports Aberdare was noted as "very remarkable" for its traditions of Taplasau Hâf (summer games/dances), races and gwrolgampau ("manly sports") which were said to have been a feature of the area since at least the 1640s. The town is also home to Yr Ynys, an historic sports ground which has the distinction of hosting the first Rugby League international, a professional Rugby League team, a football League side and an All Blacks' tour match. Today the Ynys hosts the town's Rugby union and cricket teams, as well as the Sobell Leisure Centre and the Ron Jones Athletics Stadium, a 263-seat stadium with crumb rubber track and field sports facilities, home to Aberdare Valley AAC. Cricket A cricket club was re-established at the Ynys in 1968 and was named Riverside Cricket Club in reference to its location near the banks of the river. The club would later be renamed Dare Valley CC, before finally changing its name to Aberdare CC. In 2008 the club was granted a 25-year lease on the land outside the boundary of the Ynys' pitch 1, where a club house and training nets were soon constructed. This was followed by the building of a Community Hub and Café in the 2010s. Today, the club runs 3 adult teams and 4 junior sides. Rugby League The Northern Union hired the Ynys on 1 January 1908 to host what would be the first ever international rugby league match. Played on a near frozen pitch, the match between Wales and the New Zealand All Golds proved to be a close and exciting game. The decisive score came from local star and former Aberdare RFC player, Dai "Tarw" Jones, who scored a try just minutes before the final whistle, giving Wales a 9–8 victory. The match attracted 15,000 paying spectators, with the gate receipts of £560 highlighting the commercial potential of rugby league at the Ynys. This took place at a time when the Northern Union was looking to establish professional teams across south Wales and just months after the Welsh Rugby Union had sanctioned Aberdare RFC for professionalism (banning Jones for life). As such, discussions on the establishment of a Rugby League club in Aberdare advanced quickly and on 21 July 1908, Aberdare RLFC were admitted to the Northern Union's Rugby League. On 5 September 1908 the new team played their first match against Wigan in front of a crowd of 3,000 at the Ynys. The potential for crowd support was again demonstrated on 10 November 1908, when the Ynys hosted its second international side as 5,000 spectators watched Aberdare take on the first touring Australian team. However the Aberdare club side could not replicate the heroics of the Welsh team, losing the match 10–37. Indeed, Aberdare struggled under Northern Union rules and initially high crowd numbers deteriorated with the poor results, which saw Aberdare finishing their only season in the Rugby Football League as the bottom club. Finally on 10 July 1909, Aberdare reported 'unexpected difficulties' in its finances and resigned from the Northern Rugby League. Rugby Union A rugby club representing Aberdare was recorded as early as 1876, but the modern Aberdare RFC traces its history back to a foundation of 1890. The club had great success in the early twentieth century with local star Dai 'Tarw' Jones captaining the club from 1905 to 1907. Jones gained recognition as a player in club, representative and international games. Most notably, Jones played an important part in the "Match of the century", when Wales defeated the New Zealand All Blacks. In 1907, Jones and the Aberdare club played a pivotal role in the professionalism scandal, with the Welsh Rugby Union permanently suspending the club's entire committee and a number of players (including a lifetime ban for Jones). These events would quickly lead to many of the town's players and fans switching to rugby league, with the first ever rugby league international and the founding of Aberdare RLFC in 1908. Despite the suspensions, rugby union continued in the town as the club (renamed Aberaman RFC) moved to Aberaman Park. The Ynys Stadium would host its first international rugby union side on 12 December 1935, when the 1935-36 All Blacks played a tour match against a Mid-Districts side. The All Blacks won the match 31–10 in front of a crowd of 6,000. Aberaman RFC returned to the Ynys in the 1960s. In February 1971, a clubhouse was opened at the old Crown Hotel in Gloucester Street, this was followed by the construction of a grand stand at the Ynys costing £20,000. Following the advent of professionalism in rugby union, the WRU sanctions against Aberdare were no longer applicable. As such, the club took the name Aberdare RUFC once again. Aberdare is also home to Abercwmboi RFC and Hirwaun RFC. Soccer The Ynys stadium was also home to Aberdare Athletic F.C., members of the Football League between 1921 and 1927. Aberdare finished bottom in their final season and folded in 1928 after failing to be re-elected to the league. Aberaman Athletic F.C. continued to play until World War II, and was succeeded by Aberdare & Aberaman Athletic in 1945 and Aberdare Town F.C. in 1947. The club continue to play in the Welsh Football League. Today, Aberdare Town plays in the South Wales Alliance League and are based at Aberaman Park.

In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. Aberrations cause the image formed by a lens to be blurred or distorted, with the nature of the distortion depending on the type of aberration. Aberration can be defined as a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements. An image-forming optical system with aberration will produce an image which is not sharp. Makers of optical instruments need to correct optical systems to compensate for aberration. Aberration can be analyzed with the techniques of geometrical optics. The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays. Overview With an ideal lens, light from any given point on an object would pass through the lens and come together at a single point in the image plane (or, more generally, the image surface). Real lenses do not focus light exactly to a single point, however, even when they are perfectly made. These deviations from the idealized lens performance are called aberrations of the lens. Aberrations fall into two classes: monochromatic and chromatic. Monochromatic aberrations are caused by the geometry of the lens or mirror and occur both when light is reflected and when it is refracted. They appear even when using monochromatic light, hence the name. Chromatic aberrations are caused by dispersion, the variation of a lens's refractive index with wavelength. Because of dispersion, different wavelengths of light come to focus at different points. Chromatic aberration does not appear when monochromatic light is used. Monochromatic aberrations The most common monochromatic aberrations are: Defocus Spherical aberration Coma Astigmatism Field curvature Image distortion Although defocus is technically the lowest-order of the optical aberrations, it is usually not considered as a lens aberration, since it can be corrected by moving the lens (or the image plane) to bring the image plane to the optical focus of the lens. In addition to these aberrations, piston and tilt are effects which shift the position of the focal point. Piston and tilt are not true optical aberrations, since when an otherwise perfect wavefront is altered by piston and tilt, it will still form a perfect, aberration-free image, only shifted to a different position. Chromatic aberrations Chromatic aberration occurs when different wavelengths are not focussed to the same point. Types of chromatic aberration are: Axial (or "longitudinal") chromatic aberration Lateral (or "transverse") chromatic aberration Theory of monochromatic aberration In a perfect optical system in the classical theory of optics, rays of light proceeding from any object point unite in an image point; and therefore the object space is reproduced in an image space. The introduction of simple auxiliary terms, due to Gauss, named the focal lengths and focal planes, permits the determination of the image of any object for any system. The Gaussian theory, however, is only true so long as the angles made by all rays with the optical axis (the symmetrical axis of the system) are infinitely small, i.e., with infinitesimal objects, images and lenses; in practice these conditions may not be realized, and the images projected by uncorrected systems are, in general, ill-defined and often blurred if the aperture or field of view exceeds certain limits. The investigations of James Clerk Maxwell and Ernst Abbe showed that the properties of these reproductions, i.e., the relative position and magnitude of the images, are not special properties of optical systems, but necessary consequences of the supposition (per Abbe) of the reproduction of all points of a space in image points, and are independent of the manner in which the reproduction is effected. These authors showed, however, that no optical system can justify these suppositions, since they are contradictory to the fundamental laws of reflection and refraction. Consequently, the Gaussian theory only supplies a convenient method of approximating reality; realistic optical systems fall short of this unattainable ideal. Currently, all that can be accomplished is the projection of a single plane onto another plane; but even in this, aberrations always occurs and it may be unlikely that these will ever be entirely corrected. Aberration of axial points (spherical aberration in the restricted sense) Let S (fig. 1) be any optical system, rays proceeding from an axis point O under an angle u1 will unite in the axis point O'1; and those under an angle u2 in the axis point O'2. If there is refraction at a collective spherical surface, or through a thin positive lens, O'2 will lie in front of O'1 so long as the angle u2 is greater than u1 (under correction); and conversely with a dispersive surface or lenses (over correction). The caustic, in the first case, resembles the sign > (greater than); in the second < (less than). If the angle u1 is very small, O'1 is the Gaussian image; and O'1 O'2 is termed the longitudinal aberration, and O'1R the lateral aberration of the pencils with aperture u2. If the pencil with the angle u2 is that of the maximum aberration of all the pencils transmitted, then in a plane perpendicular to the axis at O'1 there is a circular disk of confusion of radius O'1R, and in a parallel plane at O'2 another one of radius O'2R2; between these two is situated the disk of least confusion. The largest opening of the pencils, which take part in the reproduction of O, i.e., the angle u, is generally determined by the margin of one of the lenses or by a hole in a thin plate placed between, before, or behind the lenses of the system. This hole is termed the stop or diaphragm; Abbe used the term aperture stop for both the hole and the limiting margin of the lens. The component S1 of the system, situated between the aperture stop and the object O, projects an image of the diaphragm, termed by Abbe the entrance pupil; the exit pupil is the image formed by the component S2, which is placed behind the aperture stop. All rays which issue from O and pass through the aperture stop also pass through the entrance and exit pupils, since these are images of the aperture stop. Since the maximum aperture of the pencils issuing from O is the angle u subtended by the entrance pupil at this point, the magnitude of the aberration will be determined by the position and diameter of the entrance pupil. If the system be entirely behind the aperture stop, then this is itself the entrance pupil (front stop); if entirely in front, it is the exit pupil (back stop). If the object point be infinitely distant, all rays received by the first member of the system are parallel, and their intersections, after traversing the system, vary according to their perpendicular height of incidence, i.e. their distance from the axis. This distance replaces the angle u in the preceding considerations; and the aperture, i.e., the radius of the entrance pupil, is its maximum value. Aberration of elements, i.e. smallest objects at right angles to the axis If rays issuing from O (fig. 1) are concurrent, it does not follow that points in a portion of a plane perpendicular at O to the axis will be also concurrent, even if the part of the plane be very small. As the diameter of the lens increases (i.e., with increasing aperture), the neighboring point N will be reproduced, but attended by aberrations comparable in magnitude to ON. These aberrations are avoided if, according to Abbe, the sine condition, sin u'1/sin u1=sin u'2/sin u2, holds for all rays reproducing the point O. If the object point O is infinitely distant, u1 and u2 are to be replaced by h1 and h2, the perpendicular heights of incidence; the sine condition then becomes sin u'1/h1=sin u'2/h2. A system fulfilling this condition and free from spherical aberration is called aplanatic (Greek a-, privative, plann, a wandering). This word was first used by Robert Blair to characterize a superior achromatism, and, subsequently, by many writers to denote freedom from spherical aberration as well. Since the aberration increases with the distance of the ray from the center of the lens, the aberration increases as the lens diameter increases (or, correspondingly, with the diameter of the aperture), and hence can be minimized by reducing the aperture, at the cost of also reducing the amount of light reaching the image plane. Aberration of lateral object points (points beyond the axis) with narrow pencils — astigmatism A point O (fig. 2) at a finite distance from the axis (or with an infinitely distant object, a point which subtends a finite angle at the system) is, in general, even then not sharply reproduced if the pencil of rays issuing from it and traversing the system is made infinitely narrow by reducing the aperture stop; such a pencil consists of the rays which can pass from the object point through the now infinitely small entrance pupil. It is seen (ignoring exceptional cases) that the pencil does not meet the refracting or reflecting surface at right angles; therefore it is astigmatic (Gr. a-, privative, stigmia, a point). Naming the central ray passing through the entrance pupil the axis of the pencil or principal ray, it can be said: the rays of the pencil intersect, not in one point, but in two focal lines, which can be assumed to be at right angles to the principal ray; of these, one lies in the plane containing the principal ray and the axis of the system, i.e. in the first principal section or meridional section, and the other at right angles to it, i.e. in the second principal section or sagittal section. We receive, therefore, in no single intercepting plane behind the system, as, for example, a focusing screen, an image of the object point; on the other hand, in each of two planes lines O' and O" are separately formed (in neighboring planes ellipses are formed), and in a plane between O' and O" a circle of least confusion. The interval O'O", termed the astigmatic difference, increases, in general, with the angle W made by the principal ray OP with the axis of the system, i.e. with the field of view. Two astigmatic image surfaces correspond to one object plane; and these are in contact at the axis point; on the one lie the focal lines of the first kind, on the other those of the second. Systems in which the two astigmatic surfaces coincide are termed anastigmatic or stigmatic. Sir Isaac Newton was probably the discoverer of astigmation; the position of the astigmatic image lines was determined by Thomas Young; and the theory was developed by Allvar Gullstrand. A bibliography by P. Culmann is given in Moritz von Rohr's Die Bilderzeugung in optischen Instrumenten. Aberration of lateral object points with broad pencils — coma By opening the stop wider, similar deviations arise for lateral points as have been already discussed for axial points; but in this case they are much more complicated. The course of the rays in the meridional section is no longer symmetrical to the principal ray of the pencil; and on an intercepting plane there appears, instead of a luminous point, a patch of light, not symmetrical about a point, and often exhibiting a resemblance to a comet having its tail directed towards or away from the axis. From this appearance it takes its name. The unsymmetrical form of the meridional pencil—formerly the only one considered—is coma in the narrower sense only; other errors of coma have been treated by Arthur König and Moritz von Rohr, and later by Allvar Gullstrand. Curvature of the field of the image If the above errors be eliminated, the two astigmatic surfaces united, and a sharp image obtained with a wide aperture—there remains the necessity to correct the curvature of the image surface, especially when the image is to be received upon a plane surface, e.g. in photography. In most cases the surface is concave towards the system. Distortion of the image Even if the image is sharp, it may be distorted compared to ideal pinhole projection. In pinhole projection, the magnification of an object is inversely proportional to its distance to the camera along the optical axis so that a camera pointing directly at a flat surface reproduces that flat surface. Distortion can be thought of as stretching the image non-uniformly, or, equivalently, as a variation in magnification across the field. While "distortion" can include arbitrary deformation of an image, the most pronounced modes of distortion produced by conventional imaging optics is "barrel distortion", in which the center of the image is magnified more than the perimeter (figure 3a). The reverse, in which the perimeter is magnified more than the center, is known as "pincushion distortion" (figure 3b). This effect is called lens distortion or image distortion, and there are algorithms to correct it. Systems free of distortion are called orthoscopic (orthos, right, skopein to look) or rectilinear (straight lines). This aberration is quite distinct from that of the sharpness of reproduction; in unsharp, reproduction, the question of distortion arises if only parts of the object can be recognized in the figure. If, in an unsharp image, a patch of light corresponds to an object point, the center of gravity of the patch may be regarded as the image point, this being the point where the plane receiving the image, e.g., a focusing screen, intersects the ray passing through the middle of the stop. This assumption is justified if a poor image on the focusing screen remains stationary when the aperture is diminished; in practice, this generally occurs. This ray, named by Abbe a principal ray (not to be confused with the principal rays of the Gaussian theory), passes through the center of the entrance pupil before the first refraction, and the center of the exit pupil after the last refraction. From this it follows that correctness of drawing depends solely upon the principal rays; and is independent of the sharpness or curvature of the image field. Referring to fig. 4, we have O'Q'/OQ = a' tan w'/a tan w = 1/N, where N is the scale or magnification of the image. For N to be constant for all values of w, a' tan w'/a tan w must also be constant. If the ratio a'/a be sufficiently constant, as is often the case, the above relation reduces to the condition of Airy, i.e. tan w'/ tan w= a constant. This simple relation (see Camb. Phil. Trans., 1830, 3, p. 1) is fulfilled in all systems which are symmetrical with respect to their diaphragm (briefly named symmetrical or holosymmetrical objectives), or which consist of two like, but different-sized, components, placed from the diaphragm in the ratio of their size, and presenting the same curvature to it (hemisymmetrical objectives); in these systems tan w' / tan w = 1. The constancy of a'/a necessary for this relation to hold was pointed out by R. H. Bow (Brit. Journ. Photog., 1861), and Thomas Sutton (Photographic Notes, 1862); it has been treated by O. Lummer and by M. von Rohr (Zeit. f. Instrumentenk., 1897, 17, and 1898, 18, p. 4). It requires the middle of the aperture stop to be reproduced in the centers of the entrance and exit pupils without spherical aberration. M. von Rohr showed that for systems fulfilling neither the Airy nor the Bow-Sutton condition, the ratio a' cos w'/a tan w will be constant for one distance of the object. This combined condition is exactly fulfilled by holosymmetrical objectives reproducing with the scale 1, and by hemisymmetrical, if the scale of reproduction be equal to the ratio of the sizes of the two components. Zernike model of aberrations Circular wavefront profiles associated with aberrations may be mathematically modeled using Zernike polynomials. Developed by Frits Zernike in the 1930s, Zernike's polynomials are orthogonal over a circle of unit radius. A complex, aberrated wavefront profile may be curve-fitted with Zernike polynomials to yield a set of fitting coefficients that individually represent different types of aberrations. These Zernike coefficients are linearly independent, thus individual aberration contributions to an overall wavefront may be isolated and quantified separately. There are even and odd Zernike polynomials. The even Zernike polynomials are defined as and the odd Zernike polynomials as where m and n are nonnegative integers with , Φ is the azimuthal angle in radians, and ρ is the normalized radial distance. The radial polynomials have no azimuthal dependence, and are defined as and if is odd. The first few Zernike polynomials, multiplied by their respective fitting coefficients, are: where is the normalized pupil radius with , is the azimuthal angle around the pupil with , and the fitting coefficients are the wavefront errors in wavelengths. As in Fourier synthesis using sines and cosines, a wavefront may be perfectly represented by a sufficiently large number of higher-order Zernike polynomials. However, wavefronts with very steep gradients or very high spatial frequency structure, such as produced by propagation through atmospheric turbulence or aerodynamic flowfields, are not well modeled by Zernike polynomials, which tend to low-pass filter fine spatial definition in the wavefront. In this case, other fitting methods such as fractals or singular value decomposition may yield improved fitting results. The circle polynomials were introduced by Frits Zernike to evaluate the point image of an aberrated optical system taking into account the effects of diffraction. The perfect point image in the presence of diffraction had already been described by Airy, as early as 1835. It took almost hundred years to arrive at a comprehensive theory and modeling of the point image of aberrated systems (Zernike and Nijboer). The analysis by Nijboer and Zernike describes the intensity distribution close to the optimum focal plane. An extended theory that allows the calculation of the point image amplitude and intensity over a much larger volume in the focal region was recently developed (Extended Nijboer-Zernike theory). This Extended Nijboer-Zernike theory of point image or 'point-spread function' formation has found applications in general research on image formation, especially for systems with a high numerical aperture, and in characterizing optical systems with respect to their aberrations. Analytic treatment of aberrations The preceding review of the several errors of reproduction belongs to the Abbe theory of aberrations, in which definite aberrations are discussed separately; it is well suited to practical needs, for in the construction of an optical instrument certain errors are sought to be eliminated, the selection of which is justified by experience. In the mathematical sense, however, this selection is arbitrary; the reproduction of a finite object with a finite aperture entails, in all probability, an infinite number of aberrations. This number is only finite if the object and aperture are assumed to be infinitely small of a certain order; and with each order of infinite smallness, i.e. with each degree of approximation to reality (to finite objects and apertures), a certain number of aberrations is associated. This connection is only supplied by theories which treat aberrations generally and analytically by means of indefinite series. A ray proceeding from an object point O (fig. 5) can be defined by the coordinates (ξ, η). Of this point O in an object plane I, at right angles to the axis, and two other coordinates (x, y), the point in which the ray intersects the entrance pupil, i.e. the plane II. Similarly the corresponding image ray may be defined by the points (ξ', η'), and (x', y'), in the planes I' and II'. The origins of these four plane coordinate systems may be collinear with the axis of the optical system; and the corresponding axes may be parallel. Each of the four coordinates ξ', η', x', y' are functions of ξ, η, x, y; and if it be assumed that the field of view and the aperture be infinitely small, then ξ, η, x, y are of the same order of infinitesimals; consequently by expanding ξ', η', x', y' in ascending powers of ξ, η, x, y, series are obtained in which it is only necessary to consider the lowest powers. It is readily seen that if the optical system be symmetrical, the origins of the coordinate systems collinear with the optical axis and the corresponding axes parallel, then by changing the signs of ξ, η, x, y, the values ξ', η', x', y' must likewise change their sign, but retain their arithmetical values; this means that the series are restricted to odd powers of the unmarked variables. The nature of the reproduction consists in the rays proceeding from a point O being united in another point O'; in general, this will not be the case, for ξ', η' vary if ξ, η be constant, but x, y variable. It may be assumed that the planes I' and II' are drawn where the images of the planes I and II are formed by rays near the axis by the ordinary Gaussian rules; and by an extension of these rules, not, however, corresponding to reality, the Gauss image point O'0, with coordinates ξ'0, η'0, of the point O at some distance from the axis could be constructed. Writing Dξ'=ξ'-ξ'0 and Dη'=η'-η'0, then Dξ' and Dη' are the aberrations belonging to ξ, η and x, y, and are functions of these magnitudes which, when expanded in series, contain only odd powers, for the same reasons as given above. On account of the aberrations of all rays which pass through O, a patch of light, depending in size on the lowest powers of ξ, η, x, y which the aberrations contain, will be formed in the plane I'. These degrees, named by J. Petzval the numerical orders of the image, are consequently only odd powers; the condition for the formation of an image of the mth order is that in the series for Dξ' and Dη' the coefficients of the powers of the 3rd, 5th...(m-2)th degrees must vanish. The images of the Gauss theory being of the third order, the next problem is to obtain an image of 5th order, or to make the coefficients of the powers of 3rd degree zero. This necessitates the satisfying of five equations; in other words, there are five alterations of the 3rd order, the vanishing of which produces an image of the 5th order. The expression for these coefficients in terms of the constants of the optical system, i.e. the radii, thicknesses, refractive indices and distances between the lenses, was solved by L. Seidel; in 1840, J. Petzval constructed his portrait objective, from similar calculations which have never been published. The theory was elaborated by S. Finterswalder, who also published a posthumous paper of Seidel containing a short view of his work; a simpler form was given by A. Kerber. A. Konig and M. von Rohr have represented Kerber's method, and have deduced the Seidel formulae from geometrical considerations based on the Abbe method, and have interpreted the analytical results geometrically. The aberrations can also be expressed by means of the characteristic function of the system and its differential coefficients, instead of by the radii, &c., of the lenses; these formulae are not immediately applicable, but give, however, the relation between the number of aberrations and the order. Sir William Rowan Hamilton (British Assoc. Report, 1833, p. 360) thus derived the aberrations of the third order; and in later times the method was pursued by Clerk Maxwell (Proc. London Math. Soc., 1874–1875; (see also the treatises of R. S. Heath and L. A. Herman), M. Thiesen (Berlin. Akad. Sitzber., 1890, 35, p. 804), H. Bruns (Leipzig. Math. Phys. Ber., 1895, 21, p. 410), and particularly successfully by K. Schwarzschild (Göttingen. Akad. Abhandl., 1905, 4, No. 1), who thus discovered the aberrations of the 5th order (of which there are nine), and possibly the shortest proof of the practical (Seidel) formulae. A. Gullstrand (vide supra, and Ann. d. Phys., 1905, 18, p. 941) founded his theory of aberrations on the differential geometry of surfaces. The aberrations of the third order are: (1) aberration of the axis point; (2) aberration of points whose distance from the axis is very small, less than of the third order — the deviation from the sine condition and coma here fall together in one class; (3) astigmatism; (4) curvature of the field; (5) distortion. Aberration of the third order of axis points is dealt with in all text-books on optics. It is very important in telescope design. In telescopes aperture is usually taken as the linear diameter of the objective. It is not the same as microscope aperture which is based on the entrance pupil or field of view as seen from the object and is expressed as an angular measurement. Higher order aberrations in telescope design can be mostly neglected. For microscopes it cannot be neglected. For a single lens of very small thickness and given power, the aberration depends upon the ratio of the radii r:r', and is a minimum (but never zero) for a certain value of this ratio; it varies inversely with the refractive index (the power of the lens remaining constant). The total aberration of two or more very thin lenses in contact, being the sum of the individual aberrations, can be zero. This is also possible if the lenses have the same algebraic sign. Of thin positive lenses with n=1.5, four are necessary to correct spherical aberration of the third order. These systems, however, are not of great practical importance. In most cases, two thin lenses are combined, one of which has just so strong a positive aberration (under-correction, vide supra) as the other a negative; the first must be a positive lens and the second a negative lens; the powers, however: may differ, so that the desired effect of the lens is maintained. It is generally an advantage to secure a great refractive effect by several weaker than by one high-power lens. By one, and likewise by several, and even by an infinite number of thin lenses in contact, no more than two axis points can be reproduced without aberration of the third order. Freedom from aberration for two axis points, one of which is infinitely distant, is known as Herschel's condition. All these rules are valid, inasmuch as the thicknesses and distances of the lenses are not to be taken into account. The condition for freedom from coma in the third order is also of importance for telescope objectives; it is known as Fraunhofer's condition. (4) After eliminating the aberration On the axis, coma and astigmatism, the relation for the flatness of the field in the third order is expressed by the Petzval equation, S1/r(n'−n) = 0, where r is the radius of a refracting surface, n and n' the refractive indices of the neighboring media, and S the sign of summation for all refracting surfaces. Practical elimination of aberrations The classical imaging problem is to reproduce perfectly a finite plane (the object) onto another plane (the image) through a finite aperture. It is impossible to do so perfectly for more than one such pair of planes (this was proven with increasing generality by Maxwell in 1858, by Bruns in 1895, and by Carathéodory in 1926, see summary in Walther, A., J. Opt. Soc. Am. A 6, 415–422 (1989)). For a single pair of planes (e.g. for a single focus setting of an objective), however, the problem can in principle be solved perfectly. Examples of such a theoretically perfect system include the Luneburg lens and the Maxwell fish-eye. Practical methods solve this problem with an accuracy which mostly suffices for the special purpose of each species of instrument. The problem of finding a system which reproduces a given object upon a given plane with given magnification (insofar as aberrations must be taken into account) could be dealt with by means of the approximation theory; in most cases, however, the analytical difficulties were too great for older calculation methods but may be ameliorated by application of modern computer systems. Solutions, however, have been obtained in special cases. At the present time constructors almost always employ the inverse method: they compose a system from certain, often quite personal experiences, and test, by the trigonometrical calculation of the paths of several rays, whether the system gives the desired reproduction (examples are given in A. Gleichen, Lehrbuch der geometrischen Optik, Leipzig and Berlin, 1902). The radii, thicknesses and distances are continually altered until the errors of the image become sufficiently small. By this method only certain errors of reproduction are investigated, especially individual members, or all, of those named above. The analytical approximation theory is often employed provisionally, since its accuracy does not generally suffice. In order to render spherical aberration and the deviation from the sine condition small throughout the whole aperture, there is given to a ray with a finite angle of aperture u* (width infinitely distant objects: with a finite height of incidence h*) the same distance of intersection, and the same sine ratio as to one neighboring the axis (u* or h* may not be much smaller than the largest aperture U or H to be used in the system). The rays with an angle of aperture smaller than u* would not have the same distance of intersection and the same sine ratio; these deviations are called zones, and the constructor endeavors to reduce these to a minimum. The same holds for the errors depending upon the angle of the field of view, w: astigmatism, curvature of field and distortion are eliminated for a definite value, w*, zones of astigmatism, curvature of field and distortion, attend smaller values of w. The practical optician names such systems: corrected for the angle of aperture u* (the height of incidence h*) or the angle of field of view w*. Spherical aberration and changes of the sine ratios are often represented graphically as functions of the aperture, in the same way as the deviations of two astigmatic image surfaces of the image plane of the axis point are represented as functions of the angles of the field of view. The final form of a practical system consequently rests on compromise; enlargement of the aperture results in a diminution of the available field of view, and vice versa. But the larger aperture will give the larger resolution. The following may be regarded as typical: Largest aperture; necessary corrections are — for the axis point, and sine condition; errors of the field of view are almost disregarded; example — high-power microscope objectives. Wide angle lens; necessary corrections are — for astigmatism, curvature of field and distortion; errors of the aperture only slightly regarded; examples — photographic widest angle objectives and oculars. Between these extreme examples stands the normal lens: this is corrected more with regard to aperture; objectives for groups more with regard to the field of view. Long focus lenses have small fields of view and aberrations on axis are very important. Therefore zones will be kept as small as possible and design should emphasize simplicity. Because of this these lenses are the best for analytical computation. Chromatic or color aberration In optical systems composed of lenses, the position, magnitude and errors of the image depend upon the refractive indices of the glass employed (see Lens (optics) and Monochromatic aberration, above). Since the index of refraction varies with the color or wavelength of the light (see dispersion), it follows that a system of lenses (uncorrected) projects images of different colors in somewhat different places and sizes and with different aberrations; i.e. there are chromatic differences of the distances of intersection, of magnifications, and of monochromatic aberrations. If mixed light be employed (e.g. white light) all these images are formed and they cause a confusion, named chromatic aberration; for instance, instead of a white margin on a dark background, there is perceived a colored margin, or narrow spectrum. The absence of this error is termed achromatism, and an optical system so corrected is termed achromatic. A system is said to be chromatically under-corrected when it shows the same kind of chromatic error as a thin positive lens, otherwise it is said to be overcorrected. If, in the first place, monochromatic aberrations be neglected — in other words, the Gaussian theory be accepted — then every reproduction is determined by the positions of the focal planes, and the magnitude of the focal lengths, or if the focal lengths, as ordinarily happens, be equal, by three constants of reproduction. These constants are determined by the data of the system (radii, thicknesses, distances, indices, etc., of the lenses); therefore their dependence on the refractive index, and consequently on the color, are calculable. The refractive indices for different wavelengths must be known for each kind of glass made use of. In this manner the conditions are maintained that any one constant of reproduction is equal for two different colors, i.e. this constant is achromatized. For example, it is possible, with one thick lens in air, to achromatize the position of a focal plane of the magnitude of the focal length. If all three constants of reproduction be achromatized, then the Gaussian image for all distances of objects is the same for the two colors, and the system is said to be in stable achromatism. In practice it is more advantageous (after Abbe) to determine the chromatic aberration (for instance, that of the distance of intersection) for a fixed position of the object, and express it by a sum in which each component conlins the amount due to each refracting surface. In a plane containing the image point of one color, another colour produces a disk of confusion; this is similar to the confusion caused by two zones in spherical aberration. For infinitely distant objects the radius Of the chromatic disk of confusion is proportional to the linear aperture, and independent of the focal length (vide supra, Monochromatic Aberration of the Axis Point); and since this disk becomes the less harmful with an increasing image of a given object, or with increasing focal length, it follows that the deterioration of the image is proportional to the ratio of the aperture to the focal length, i.e. the relative aperture. (This explains the gigantic focal lengths in vogue before the discovery of achromatism.) Examples: Newton failed to perceive the existence of media of different dispersive powers required by achromatism; consequently he constructed large reflectors instead of refractors. James Gregory and Leonhard Euler arrived at the correct view from a false conception of the achromatism of the eye; this was determined by Chester More Hall in 1728, Klingenstierna in 1754 and by Dollond in 1757, who constructed the celebrated achromatic telescopes. (See telescope.) Glass with weaker dispersive power (greater ) is named crown glass; that with greater dispersive power, flint glass. For the construction of an achromatic collective lens ( positive) it follows, by means of equation (4), that a collective lens I. of crown glass and a dispersive lens II. of flint glass must be chosen; the latter, although the weaker, corrects the other chromatically by its greater dispersive power. For an achromatic dispersive lens the converse must be adopted. This is, at the present day, the ordinary type, e.g., of telescope objective; the values of the four radii must satisfy the equations (2) and (4). Two other conditions may also be postulated: one is always the elimination of the aberration on the axis; the second either the Herschel or Fraunhofer Condition, the latter being the best vide supra, Monochromatic Aberration). In practice, however, it is often more useful to avoid the second condition by making the lenses have contact, i.e. equal radii. According to P. Rudolph (Eder's Jahrb. f. Photog., 1891, 5, p. 225; 1893, 7, p. 221), cemented objectives of thin lenses permit the elimination of spherical aberration on the axis, if, as above, the collective lens has a smaller refractive index; on the other hand, they permit the elimination of astigmatism and curvature of the field, if the collective lens has a greater refractive index (this follows from the Petzval equation; see L. Seidel, Astr. Nachr., 1856, p. 289). Should the cemented system be positive, then the more powerful lens must be positive; and, according to (4), to the greater power belongs the weaker dispersive power (greater ), that is to say, crown glass; consequently the crown glass must have the greater refractive index for astigmatic and plane images. In all earlier kinds of glass, however, the dispersive power increased with the refractive index; that is, decreased as increased; but some of the Jena glasses by E. Abbe and O. Schott were crown glasses of high refractive index, and achromatic systems from such crown glasses, with flint glasses of lower refractive index, are called the new achromats, and were employed by P. Rudolph in the first anastigmats (photographic objectives). Instead of making vanish, a certain value can be assigned to it which will produce, by the addition of the two lenses, any desired chromatic deviation, e.g. sufficient to eliminate one present in other parts of the system. If the lenses I. and II. be cemented and have the same refractive index for one color, then its effect for that one color is that of a lens of one piece; by such decomposition of a lens it can be made chromatic or achromatic at will, without altering its spherical effect. If its chromatic effect () be greater than that of the same lens, this being made of the more dispersive of the two glasses employed, it is termed hyper-chromatic. For two thin lenses separated by a distance the condition for achromatism is ; if (e.g. if the lenses be made of the same glass), this reduces to , known as the condition for oculars. If a constant of reproduction, for instance the focal length, be made equal for two colors, then it is not the same for other colors, if two different glasses are employed. For example, the condition for achromatism (4) for two thin lenses in contact is fulfilled in only one part of the spectrum, since varies within the spectrum. This fact was first ascertained by J. Fraunhofer, who defined the colors by means of the dark lines in the solar spectrum; and showed that the ratio of the dispersion of two glasses varied about 20% from the red to the violet (the variation for glass and water is about 50%). If, therefore, for two colors, a and b, , then for a third color, c, the focal length is different; that is, if c lies between a and b, then , and vice versa; these algebraic results follow from the fact that towards the red the dispersion of the positive crown glass preponderates, towards the violet that of the negative flint. These chromatic errors of systems, which are achromatic for two colors, are called the secondary spectrum, and depend upon the aperture and focal length in the same manner as the primary chromatic errors do. In fig. 6, taken from M. von Rohr's Theorie und Geschichte des photographischen Objectivs, the abscissae are focal lengths, and the ordinates wavelengths. The Fraunhofer lines used are shown in adjacent table. The focal lengths are made equal for the lines C and F. In the neighborhood of 550 nm the tangent to the curve is parallel to the axis of wavelengths; and the focal length varies least over a fairly large range of color, therefore in this neighborhood the color union is at its best. Moreover, this region of the spectrum is that which appears brightest to the human eye, and consequently this curve of the secondary on spectrum, obtained by making , is, according to the experiments of Sir G. G. Stokes (Proc. Roy. Soc., 1878), the most suitable for visual instruments (optical achromatism,). In a similar manner, for systems used in photography, the vertex of the color curve must be placed in the position of the maximum sensibility of the plates; this is generally supposed to be at G'; and to accomplish this the F and violet mercury lines are united. This artifice is specially adopted in objectives for astronomical photography (pure actinic achromatism). For ordinary photography, however, there is this disadvantage: the image on the focusing-screen and the correct adjustment of the photographic sensitive plate are not in register; in astronomical photography this difference is constant, but in other kinds it depends on the distance of the objects. On this account the lines D and G' are united for ordinary photographic objectives; the optical as well as the actinic image is chromatically inferior, but both lie in the same place; and consequently the best correction lies in F (this is known as the actinic correction or freedom from chemical focus). Should there be in two lenses in contact the same focal lengths for three colours a, b, and c, i.e. , then the relative partial dispersion must be equal for the two kinds of glass employed. This follows by considering equation (4) for the two pairs of colors ac and bc. Until recently no glasses were known with a proportional degree of absorption; but R. Blair (Trans. Edin. Soc., 1791, 3, p. 3), P. Barlow, and F. S. Archer overcame the difficulty by constructing fluid lenses between glass walls. Fraunhofer prepared glasses which reduced the secondary spectrum; but permanent success was only assured on the introduction of the Jena glasses by E. Abbe and O. Schott. In using glasses not having proportional dispersion, the deviation of a third colour can be eliminated by two lenses, if an interval be allowed between them; or by three lenses in contact, which may not all consist of the old glasses. In uniting three colors an achromatism of a higher order is derived; there is yet a residual tertiary spectrum, but it can always be neglected. The Gaussian theory is only an approximation; monochromatic or spherical aberrations still occur, which will be different for different colors; and should they be compensated for one color, the image of another color would prove disturbing. The most important is the chromatic difference of aberration of the axis point, which is still present to disturb the image, after par-axial rays of different colors are united by an appropriate combination of glasses. If a collective system be corrected for the axis point for a definite wavelength, then, on account of the greater dispersion in the negative components — the flint glasses, — overcorrection will arise for the shorter wavelengths (this being the error of the negative components), and under-correction for the longer wavelengths (the error of crown glass lenses preponderating in the red). This error was treated by Jean le Rond d'Alembert, and, in special detail, by C. F. Gauss. It increases rapidly with the aperture, and is more important with medium apertures than the secondary spectrum of par-axial rays; consequently, spherical aberration must be eliminated for two colors, and if this be impossible, then it must be eliminated for those particular wavelengths which are most effectual for the instrument in question (a graphical representation of this error is given in M. von Rohr, Theorie und Geschichte des photographischen Objectivs). The condition for the reproduction of a surface element in the place of a sharply reproduced point — the constant of the sine relationship must also be fulfilled with large apertures for several colors. E. Abbe succeeded in computing microscope objectives free from error of the axis point and satisfying the sine condition for several colors, which therefore, according to his definition, were aplanatic for several colors; such systems he termed apochromatic. While, however, the magnification of the individual zones is the same, it is not the same for red as for blue; and there is a chromatic difference of magnification. This is produced in the same amount, but in the opposite sense, by the oculars, which Abbe used with these objectives (compensating oculars), so that it is eliminated in the image of the whole microscope. The best telescope objectives, and photographic objectives intended for three-color work, are also apochromatic, even if they do not possess quite the same quality of correction as microscope objectives do. The chromatic differences of other errors of reproduction seldom have practical importance.

Grant made her debut as a teenager, gaining fame in Christian music during the 1980s with such hits as "Father's Eyes", "El Shaddai", and "Angels". In the mid-1980s, she began broadening her audience and soon became one of the first CCM artists to cross over into mainstream pop on the heels of her successful albums Unguarded and Lead Me On. In 1986, she scored her first Billboard Hot 100 no. 1 song in a duet with Peter Cetera, "The Next Time I Fall". In 1991, she released the blockbuster album Heart in Motion which became her best-selling album to date, topping the Billboard Christian album chart for 32 weeks, selling five million copies in the U.S. and producing her second no. 1 pop single "Baby Baby" and produced another three top 10 on Billboard Hot 100; "That's What Love Is For", "Every Heartbeat" and "Good for Me". She is the author of several books, including a memoir, Mosaic: Pieces of My Life So Far, and a book based on the popular Christmas song "Breath of Heaven (Mary's Song)" that she co-wrote. Background Early life and career Born in Augusta, Georgia, Grant is the youngest of four sisters. Her family settled in Nashville in 1967. She is a great-granddaughter of Nashville philanthropist A. M. Burton (founder of Life and Casualty Insurance Company, eponym of Nashville's Life & Casualty Tower, WLAC Radio, and WLAC-TV) and Lillie Burton. She has acknowledged the influence of the Burtons on her development as a musician, starting with their common membership in Nashville's Ashwood Church of Christ. In 1976, Grant wrote her first song ("Mountain Top"), performed in public for the first time at Harpeth Hall School, the all-girls school she attended in Nashville. She recorded a demo tape for her parents with church youth-leader Brown Bannister. While Bannister was dubbing a copy of the tape, Chris Christian, the owner of the recording studio heard the demo and called Word Records. He played it over the phone and she was offered a recording contract, five weeks before her 16th birthday. In 1977, she recorded her first album, Amy Grant, produced by Brown Bannister, who would also produce her next 11 albums. It was released in early 1978, one month before her high-school graduation. Toward the end of 1978 she performed her first ticketed concert after beginning her first year at Furman University. In May 1979, while at the album-release party for her second album, My Father's Eyes, Grant met Gary Chapman, who had written the title track and would become her first husband. Grant and Chapman toured together in mid-1979. In late 1980, she transferred to Vanderbilt University where she was a member of the sorority Kappa Alpha Theta. Grant then made a few more albums before dropping out of college to pursue a career in music—Never Alone, followed by a pair of live albums in 1981 (In Concert and In Concert Volume Two), both backed by an augmented edition of the DeGarmo & Key band. It was during these early shows that Grant also established one of her concert trademarks: performing barefoot. To date, Grant continues to take off her shoes midway through performances, as she has said, "it is just more comfortable." 1982 saw the release of her breakthrough album Age to Age. The album contains the signature track, "El Shaddai" (written by Michael Card) and the Grant-Chapman penned song, "In a Little While". "El Shaddai" was later awarded one of the "Songs of the Century" by the RIAA in 2001. Grant received her first Grammy Award for Best Contemporary Gospel Performance, as well as two GMA Dove Awards for Gospel Artist of the Year and Pop/Contemporary Album of the Year. Age to Age became the first Christian album by a solo artist to be certified gold (1983) and the first Christian album to be certified platinum (1985). In the mid-1980s, Grant began touring and recording with young up-and-coming songwriter Michael W. Smith. Grant and Smith continue to have a strong friendship and creative relationship, often writing songs for or contributing vocals to each other's albums, and as of 2019, often touring together annually during November and December putting on Christmas concerts. During the 1980s, Grant was also a backup singer for Bill Gaither. Grant followed this album with the first of her Christmas albums, which would later be the basis for her holiday shows. In 1984, she released another pop-oriented Christian hit, Straight Ahead, earning Grant her first appearance at the Grammy Awards show in 1985. The head of NBC took notice of Grant's performance and called her manager to book her for her own Christmas special. Widening audience Shortly after Grant established herself as the "Queen of Christian Pop" she changed directions to widen her fan base (and hence her musical message). Her goal was to become the first Christian singer-songwriter who was also successful as a contemporary pop singer. Unguarded (1985) surprised some fans for its very mainstream sound (and Grant's leopard-print jacket, in four poses for four different covers). "Find a Way", from Unguarded, became one of the few non-Christmas Christian songs to hit the Billboard Top 40 list, also reaching No. 7 on the Adult Contemporary chart. She also scored No. 18 on Billboard AC in 1986 with "Stay for Awhile". Grant scored her first Billboard No. 1 song in 1986 with "The Next Time I Fall", a duet with former Chicago singer/bassist Peter Cetera. That year, she also recorded a duet with singer Randy Stonehill for his Love Beyond Reason album, titled "I Could Never Say Goodbye", and recorded The Animals' Christmas with Art Garfunkel. Lead Me On (1988) contained many songs which were about Christianity and love relationships, but some interpreted it as not being enough of a "Christian" record. Years later Lead Me On would be chosen as the greatest Contemporary Christian album of all time by CCM Magazine. The mainstream song "Saved by Love" was a minor hit, receiving airplay on radio stations featuring the newly emerging Adult Contemporary format. The album's title song received some pop radio airplay and crossed over to No. 96 on the Billboard Hot 100, and "1974 (We Were Young)" and "Saved By Love" also charted as Adult Contemporary songs. In 1989, she appeared in a Target ad campaign, performing songs off the album. In the mainstream When Heart in Motion was released in 1991, many fans were surprised that the album was so clearly one of contemporary pop music. Grant's desire to widen her audience was frowned upon by the confines of the popular definitions of ministry at the time. The track "Baby Baby" (written for Grant's newborn daughter Millie, of whom Grant wrote, her "six-week-old face was my inspiration") became a pop hit (hitting No. 1 on the Billboard Hot 100), and Grant was established as a name in the mainstream music world. "Baby Baby" received Grammy nominations for Best Female Pop Vocal Performance, and Record and Song of the Year (although it failed to win in any of those categories). Four other hits from the album made the Pop top 20: "Every Heartbeat" (No. 2), "That's What Love Is For" (No. 7), "Good for Me" (No. 8), and "I Will Remember You" (No. 20). On the Adult Contemporary chart, all five songs were top 10 hits, with two of the five ("Baby Baby" and "That's What Love Is For") reaching No. 1. Many Christian fans remained loyal, putting the album atop Billboard Contemporary Christian Chart for 32 weeks. Heart in Motion is Grant's best-selling album, having sold over five million copies according to the RIAA. Grant followed the album with her second Christmas album, Home For Christmas in 1992, which included the song "Breath of Heaven (Mary's Song)", written by Chris Eaton and Grant, and would later be covered by many artists, including Donna Summer, Jessica Simpson (who acknowledged Grant as one of her favorite artists), Vince Gill, Sara Groves, Point of Grace, Gladys Knight, and Broadway star Barbara Cook. House of Love in 1994 continued in the same vein, boasting catchy pop songs mingled with spiritual lyrics. The album was a multi-platinum success and produced the pop hit "Lucky One" (No. 18 pop and No. 2 AC; No. 1 on Radio & Records) as well as the title track (a duet with country music star and future husband Vince Gill) (No. 37 pop) and a cover of Joni Mitchell's frequently covered "Big Yellow Taxi" (No. 67 pop) (in which she changed the line "And they charged the people a dollar and a half just to see'em" to "And then they charged the people 25 bucks just to see'em"). After she covered the 10cc song "The Things We Do for Love" for the Mr. Wrong soundtrack, Behind the Eyes was released in September 1997. The album struck a much darker note, leaning more towards downtempo, acoustic soft-rock songs, with more mature (yet still optimistic) lyrics. She called it her "razor blades and Prozac" album. Although "Takes a Little Time" was a moderate hit single, the album failed to sell like the previous two albums, which had both gone multi-platinum. Behind The Eyes was eventually certified Gold by the RIAA. The video for "Takes a Little Time" was a new direction for Grant; with a blue light filter, acoustic guitar, the streets and characters of New York City, and a plot, Grant was re-cast as an adult light rocker. She followed up "Behind The Eyes" with A Christmas To Remember, her third Christmas album, in 1999. The album was certified gold in 2000. Following the 9/11 attacks Grant's "I Will Remember You" saw a resurgence in popularity as many radio DJs mixed a special tribute version of the song. In the same year Grant won $125,000 for charity on the "Rock Star Edition" of Who Wants to Be a Millionaire? Return to Gospel Roots Grant returned to Christian pop with the 2002 release of an album of hymns titled Legacy... Hymns and Faith. The album featured a Vince Gill-influenced mix of bluegrass and pop and marked Grant's 25th anniversary in the music industry. Grant followed this up with Simple Things in 2003. The album did not have the success of her previous pop or gospel efforts. Soon after Simple Things, Grant and Interscope/A&M parted ways. The same year, Grant was inducted into the Gospel Music Hall of Fame by the Gospel Music Association, an industry trade organization of which she is a longstanding member, in her first year of eligibility. Grant released a sequel in 2005 titled Rock of Ages...Hymns and Faith. Grant joined the reality television phenomenon by hosting Three Wishes, a show in which she and a team of helpers make wishes come true for small-town residents. The show debuted on NBC in the fall of 2005 however it was canceled at the end of its first season due to high production costs. After Three Wishes was canceled, Grant won her 6th Grammy Award for Rock of Ages... Hymns & Faith. In a February 2006 webchat, Grant said she believes her "best music is still ahead". In April 2006, a live CD/DVD titled Time Again... Amy Grant Live was recorded in Fort Worth, Texas, at Bass Performance Hall. (Grant's first paid public performance was at the Will Rogers Auditorium in Fort Worth.) The concert was released on September 26, 2006. In addition to receiving a star on the Hollywood Walk of Fame, media appearances included write-ups in CCM Magazine, and a performance on The View. In a February 2007 web chat on her web site, Grant discussed a book she was working on titled Mosaic: Pieces of My Life So Far, saying, "It's not an autobiography, but more a collection of memories, song lyrics, poetry and a few pictures." The book was released on October 16, 2007. In November, it debuted at No. 35 on the New York Times Best Seller list. In the same web chat, Grant noted that she is "anxious to get back in the studio after the book is finished, and reinvent myself as an almost-50 performing woman". 2007 was Grant's 30th year in music. She left Word/Warner, and contracted with EMI CMG who re-released her regular studio albums as remastered versions on August 14, 2007. Marking the start of Grant's new contract is a career-spanning greatest hits album, with all the songs digitally remastered. The album was released as both a single-disc CD edition, and a two-disc CD/DVD Special Edition, the DVD featuring music videos and interviews. Grant appeared with Gill on The Oprah Winfrey Show for a holiday special in December 2007. Grant has plans to appear on CMT, a Food Network special, the Gospel Music Channel, and The Hour of Power. In February 2008, Grant joined the writing team from Compassionart as a guest vocalist at the Abbey Road studios, London, to record a song called "Highly Favoured", which was included on the album CompassionArt. On June 24, 2008, Grant re-released her 1988 album, Lead Me On, in honor of its 20th anniversary. The two-disc release includes the original album and a second disc with new acoustic recordings, live performances from 1989, and interviews with Amy. Grant recreated the Lead Me On tour in the fall of 2008. On June 27, 2008, at Creation Festival Northeast she performed "Lead Me On" and a few other songs backed by Hawk Nelson. At the end of the concert, Grant returned to the stage and sang "Thy Word". She appeared on the 2008 album Anne Murray Duets: Friends & Legends singing "Could I Have This Dance". On May 5, 2009, Grant released an EP containing two new songs, "She Colors My Day", and "Unafraid", as well as the previously released songs "Baby Baby" and "Oh How the Years Go By". The EP, exclusively through iTunes, benefited the Entertainment Industry Foundation's (EIF) Women's Cancer Research Fund. In 2010, Grant released Somewhere Down the Road, featuring the hit single "Better Than a Hallelujah", which peaked at No. 8 on Billboard Top Christian Songs chart. When asked about the new album during an interview with CBN.com, Grant says, "... my hope is just for those songs to provide companionship, remind myself and whoever else is listening what's important. I feel like songs have the ability to connect us to ourselves and to each other, and to our faith, to the love of Jesus, in a way that conversation doesn't do. Songs kind of slip in and move you before you realize it." In September 2012, Grant took part in a campaign called "30 Songs / 30 Days" to support Half the Sky: Turning Oppression into Opportunity for Women Worldwide, a multi-platform media project inspired by Nicholas Kristof and Sheryl WuDunn's book. Grant's next album, How Mercy Looks from Here, was released on May 14, 2013, and was produced by Marshall Altman. The album reached No. 12 on the Billboard 200 chart, making it her highest-charting album since 1997's Behind the Eyes. Two singles were released from the album: "Don't Try So Hard" and "If I Could See", both of which charted on the US Billboard Hot Christian Songs chart. On August 19, 2014, she released an album of hits remixed by well known engineers and DJs. The album was titled In Motion: The Remixes. It charted at 110 on the US Billboard 200 chart and at No. 5 on the US Dance chart. To promote the album, several new remix EPs were released on iTunes the following month including "Find a Way, "Stay for Awhile", "Baby Baby, "Every Heartbeat" and "That's What Love Is For". Due to club play of the remixes of "Baby Baby" and "Every Heartbeat", they charted at No. 3 and 13, respectively on the U.S. Dance Chart. This marked her first appearance on that chart in 23 years. On September 30, 2014, Grant released a new single titled "Welcome Yourself". In honor of Breast Cancer Awareness Month, proceeds of the single go to breast cancer research. On February 12, 2015, she announced a new compilation album titled Be Still and Know... Hymns & Faith, to be released. The album was released on April 14, 2015, and charted at No. 7 in the U.S. on the Billboard Christian Albums chart. . Grant released a Christmas album on October 21, 2016, Tennessee Christmas, which is a combination of classic Christmas songs and original material. It charted in the U.S. at No. 31 on the Billboard 200 and at No. 3 on the Billboard Top Holiday Albums chart. The single from the album, "To Be Together", reached No. 32 on the Hot Christian Songs chart and No. 19 on the Holiday Digital Song Sales chart. She supported the album with a series of Christmas concerts with Vince Gill at the Ryman Auditorium. She also toured the U.S. and Canada with Christmas concerts accompanied by Michael W. Smith and season 9 winner of The Voice, Jordan Smith. In February 2017, she released a new song, "Say It With a Kiss", with accompanying video. During November and December 2017, Grant performed another series of Christmas concerts with Vince Gill at the Ryman and embarked on another U.S. and Canada Christmas tour with Michael W. Smith and Jordan Smith. Grant has been a guest narrator for Disney's Candlelight Processional at Walt Disney World in 2012, 2013, and 2015. Personal life On June 19, 1982, Grant married fellow Christian musician Gary Chapman. Their marriage produced three children. In March 1999 she filed for divorce from Chapman. On March 10, 2000, Grant married country singer-songwriter Vince Gill, who had been previously married to country singer Janis Oliver of Sweethearts of the Rodeo. Grant and Gill have one daughter together, Corrina Grant Gill, born March 12, 2001. In the November 1999 CCM Magazine, Grant explained why she left Chapman and married Gill: In June 2020, Grant had an open-heart surgery to repair partial anomalous pulmonary venous return (PAPVR), a congenital heart condition. On July 27, 2022, Grant was injured and briefly hospitalized when she fell from her bicycle while riding near Nashville's Harpeth Hills Golf Course. She sustained cuts and abrasions. Public views and perception Along with praise for her contributions to the contemporary Christian genre, Grant has also generated controversy within the Christian community, from "complaints that she was too worldly and too sexy" to a "barrage of condemnation" following her divorce and remarriage. In an interview early in her career, Grant stated, "I have a healthy sense of right and wrong, but sometimes, for example, using foul, exclamation-point words among friends can be good for a laugh." The article which was based on that interview was constructed in such a manner so as to make it appear as though Grant condoned premarital sex. Later Grant reflected on how the article misrepresented her views, stating: "We probably talked for two hours about sexual purity, but when the interview finally came out he worded it in such a way that it sounded like I condoned premarital sex. So I picked up that article and thought, 'You've made me say something I've never said, and you've totally disregarded two hours of Bible put in one flippant comment that I made about a moan.'"

Aberdeen (Lakota: Ablíla) is a city in and the county seat of Brown County, South Dakota, United States, located approximately northeast of Pierre. The city population was 28,495 at the 2020 census, making it the third most populous city in the state after Sioux Falls and Rapid City. Aberdeen is home of Northern State University. History Settlement Before Aberdeen or Brown County was inhabited by European settlers, it was inhabited by the Sioux Indians from approximately 1700 to 1879. Europeans entered the region for business, founding fur trading posts during the 1820s; these trading posts operated until the mid-1830s. The first "settlers" of this region were the Arikara Indians, but they would later be joined by others. The first group of Euro-American settlers to reach the area that is now Brown County was a party of four people, three horses, two mules, fifteen cattle, and two wagons. This group of settlers was later joined by another group the following spring, and, eventually, more settlers migrated toward this general area, currently known as Columbia, South Dakota. This town was established on June 15, 1879, was settled in 1880, and was incorporated in 1882. Creation of the town Aberdeen, like many towns of the Midwest, was built around the newly developing railroad systems. Aberdeen was first officially plotted as a town site on January 3, 1881, by Charles Prior, the superintendent of the Minneapolis office of the Chicago, Milwaukee, and St. Paul Railroad, or the Milwaukee Road for short, which was presided over by Alexander Mitchell, Charles Prior's boss, who was responsible for the choice of town names. He was born in Aberdeen, Scotland, after which the town of Aberdeen was named. Aberdeen was officially founded on July 6, 1881, the date of the first arrival of a Milwaukee Railroad train. Aberdeen then operated under a city charter granted by the Territorial Legislature in March 1883. As Aberdeen grew, many businesses and buildings were constructed along Aberdeen's Main Street. However, this soon became a problem due to Aberdeen's periodic flooding, which led to it being referred to as "The Town in the Frog Pond". At first, this unique condition presented no problem to the newly constructed buildings because it had not rained very much but, when heavy rains fell, the Pond reappeared and flooded the basements of every building on Main Street, causing many business owners and home owners much turmoil. When this flooding happened, the city had one steam-powered pump that had to be used to dry out the entire area that had been flooded, which would take days, if not weeks – and more often than not, it would have rained again in this time period and caused even more flooding, even in the basements that had already been emptied of the water. When the water was gone from the basements, the city still had to deal with the mud that also resulted from the heavy rains. The city decided in 1882 to build an artesian ditch to control the "Frog Pond" effects; the plan was later upgraded and developed into an artesian well in 1884 to combat the heavy rains and keep the basements from flooding. The artesian well was designed by the city engineers to prevent flooding and develop a water system. However, during the digging of the well, the water stream that was found underground was too powerful to be contained. The water came blasting out with violent force and had the entire Main Street submerged in up to four feet of water. The engineers realized the previous flaws of the artesian well plan and soon added a gate valve to the well to control the flow of water, giving Aberdeen its first working water supply. Aberdeen had four different railroad companies with depots built in the newly developing town. With these four railroads intersecting here, Aberdeen soon became known as the "Hub City of the Dakotas". When looking down on Aberdeen from above, the railroad tracks converging in Aberdeen resembled the spokes of a wheel converging at a hub, hence the name "Hub City of the Dakotas". These four railroad companies are the reason why Aberdeen was able to grow and flourish as it did. The only railroad still running through Aberdeen is the BNSF Railway. L. Frank Baum, who was later author of the book The Wonderful Wizard of Oz and its many sequels, lived here with his wife and children from 1888 to 1891. He ran a fancy goods store, Baum's Bazaar, for over a year, which failed. He later published one of the city's then nine newspapers, where he used his editorials to campaign for women's suffrage. (A suffrage amendment to the new South Dakota constitution was on the ballot.) The city's small amusement park has some features reflective of the Oz series. After his sojourn in Aberdeen he moved to Chicago, Illinois in 1892. Geography Aberdeen is located in northeastern South Dakota, in the James River valley, approximately west of the river. The James River enters northeastern South Dakota in Brown County, where it is dammed to form two reservoirs northeast of Aberdeen. The city is bisected by Moccasin Creek, a slow-moving waterway which flows south and then northeast to the James River. According to the United States Census Bureau, the city has a total area of , of which is land and is water. Climate Aberdeen experiences a humid continental climate (Köppen Dfa) influenced by its position far from moderating bodies of water. This brings four distinct seasons, a phenomenon that is characterized by hot, relatively humid summers and cold, dry winters, and it lies in USDA Hardiness Zone 4b. The monthly daily average temperature ranges from in January to in July, while there are 16 days of + highs and 38 days with sub- lows annually. Snowfall occurs mostly in light to moderate amounts during the winter, totaling . Precipitation, at annually, is concentrated in the warmer months. Extreme temperatures have ranged from on January 12, 1912, and February 8, 1895, to on July 6 and 15, 1936, although a reading occurred as recently as January 15, 2009. The National Oceanographic and Atmospheric Administration maintains a National Weather Service office in Aberdeen. Their area of responsibility includes northern and eastern South Dakota and two counties in west-central Minnesota. Demographics Aberdeen is the principal city of the Aberdeen Micropolitan Statistical Area, which includes all of Brown and Edmunds counties and has a population of 42,287 in 2020. 2010 census At the 2010 census, there were 26,091 people, 11,418 households and 6,354 families residing in the city.

Aberdour (; Scots: , ) is a scenic and historic village on the south coast of Fife, Scotland. It is on the north shore of the Firth of Forth, looking south to the island of Inchcolm and its Abbey, and to Leith and Edinburgh beyond. According to the 2011 census, the village has a population of 1,633. The village's winding High Street lies a little inland from the coast. Narrow lanes run off it, providing access to the more hidden parts of the village and the shoreline itself. The village nestles between the bigger coastal towns of Burntisland to the east and Dalgety Bay to the west. The parish of Aberdour takes its name from this village, and had a population of 1,972 at the 2011 Census. Etymology Aberdour means 'mouth of the Dour'. The first element is the Pictish word aber 'river mouth'. The name of the Dour Burn, which enters the River Forth at the village's harbour, is from Pictish 'water'. A cognate of this word is also seen in Dover and Andover. The Pictish word was subsequently changed to Gaelic dobhar. Aberdour is recorded in 1179 as Abirdoure and in 1126 as "Abirdaur". History For much of its history Aberdour was two villages, Wester Aberdour and Easter Aberdour, on either side of the Dour Burn; however this distinction was blurred by the 19th century arrival of the railway. In the 18th century Aberdour's harbour was improved by the addition of a stone pier to help handle the coal traffic from nearby collieries. However, in the 1850s the traffic changed dramatically, and Aberdour Harbour became a popular destination for pleasure steamers from Leith. This in turn led to the building of a deeper water pier a little around the bay at Hawkcraig, and to the development of hotels and many of the other services still on view today in the village. The railway came to Aberdour in 1890, with the building of the line east from the newly opened Forth Bridge. The station has won many "best kept station" awards. Geography The A921, the main road along the south coast of Fife, leads down the High Street of Wester Aberdour, before kinking sharply left to cross the railway line, then right again to progress through Easter Aberdour's Main Street. Wester Aberdour has a narrow through road more closely hemmed in by shops and hotels. A number of vernacular buildings of the 17th-early 19th centuries add to the historic scene. Close to the railway bridge, three lanes continue eastwards, presumably once the route of the original High Street before the arrival of the railway. One now leads to Aberdour railway station, a beautifully kept and cared for example of a traditional station, in keeping with its role of transporting at least a quarter of the village's working population to their work each day. A second lane leads alongside the railway line to Aberdour Castle, while a third leads to the restored Aberdour House. A little further west, a narrow road closely lined with high walls, Shore Road, leads down to the West Sands and the Harbour. For many this area is the highlight of any visit to Aberdour; parking at the foot of Shore Road is usually at a premium. Another road leads coastwards from Easter Aberdour. Hawkcraig Road leads past St Fillan's Church and through Silversand Park, home to Aberdour Shinty Club, en route to the much better parking area on Hawkcraig. This was formerly a sandstone quarry and then used as the council refuse tip before becoming a carpark, part of the overgrown and rocky bluff separating Aberdour's two bays. From here is it a short walk to the Silver Sands, Aberdour's busiest and most popular beach. On the west side of Hawkcraig Point there is a short concrete jetty that was used as part of the development of radio controlled torpedoes during World War I. The foundations of the Radio Hut can still be seen in the lea of the hill. Landmarks Virtually between the two former settlements, though actually part of Easter Aberdour, lies Aberdour Castle. This started life as a modest hall house on a site overlooking the Dour Burn in the 13th century. The oldest part of the present semi-ruin constitutes one of the earliest surviving stone castles in mainland Scotland. Over the next four hundred years the Castle was successively developed according to contemporary architectural ideas. Notable are the parts, still largely roofed, built by the Earls of Morton, with refined Renaissance detail, in the second half of the 16th century. A fire in the late 17th century was followed by some repairs, but in 1725 the family purchased 17th-century Aberdour House, on the west side of the burn and in Wester Aberdour, and the medieval Castle was allowed to fall into relative decay. Aberdour Castle is now in the care of Historic Environment Scotland and open to the public (entrance charge). After a period of dereliction Aberdour House was developed for residential use in the early 1990s. Neighbouring St Fillan's Church is one of the best-preserved medieval parish churches in Scotland, dating largely to the 12th century and originally under control of Inchcolm Abbey. A south arcade was added to the nave in the early 16th century (open in summer). It was controversially considered for closure by the Church of Scotland in 2022, but a campaign was mounted to keep it open. The Aberdour obelisk was built by Lord Morton on his departure from the village to relocate to a large home in Edinburgh, it was built so he could see his former hometown from his new house when he looked through binoculars – it stands in a cowfield between the castle and the beach. Culture Aberdour hosts an annual festival, which runs from late July to early August and features musical events, shows, sporting events and children's events. Aberdour was a 2005 finalist in the prestigious "Beautiful Scotland in Bloom" awards. It was nominated for "Best Coastal Resort" in Scotland along with St Andrews in Fife, North Berwick in East Lothian, and Rothesay in Argyll and Bute. In 2014 Aberdour was voted Best Coastal Village in Fife and Best Small Coastal Village in Scotland. It also received a Gold Award in Beautiful Fife and Beautiful Scotland. In 2018 Aberdour was voted the second-best place to live in Scotland by The Sunday Times list of Best Places to Live Aberdour is home to Fife's only senior shinty club. Aberdour Shinty Club field teams in both the men's and women's senior national leagues. Aberdour is one of the few communities outside of Turkmenistan to celebrate Melon Day on the second sunday of every August. Aberdour's beaches Aberdour has two beaches – the Silver Sands, and the Black Sands. The Silver Sands are located on the East side of the village, and have previously held a "Blue flag" beach award, which denotes an exemplary standard of cleanliness, facilities, safety, environmental education and management. New facilities are currently under construction by Fife Council, which will much improve the beach throughout the year. The Black Sands (also known as the West Beach), as the contrasting name would suggest, have a rockier and darker sand, and are also popular with visitors exploring the rock caves and unique sea life. During the summer months (April–September), dogs are banned from the Silver Sands but they are allowed all year round at the West Beach. The two beaches are linked by part of the Fife Coastal Path which also takes hikers past the harbour and the Hawkcraig – a popular rock climbing location. Silver Sands is becoming more popular with open water swimmers, who swim daily in the sea, both as a leisure pursuit, and as training for open water competition. The bay provides safety from the currents, although only the adventurous swim round to the harbour. Several scenes of Richard Jobson's 2003 movie 16 Years of Alcohol were filmed at the Black Sands in Aberdour. Inchcolm The island of Inchcolm, or Island (Gaelic innis) of Columba, a quarter of a mile from the shore, forms part of the parish of Aberdour. Its name implies associations dating back to the time of Columba and, although undocumented before the 12th century, it may have served the monks of the Columban family as an 'Iona of the east' from early times. During the First and Second World Wars, Inchcolm was occupied by the army as part of the defences of the Firth of Forth. There are extensive remains of gun emplacements, barracks, etc. from these periods. The island is notable for its wildlife, especially seabirds and seals. These draw many visitors in summer, along with the remains of the historic Abbey, and is a popular setting for weddings. Notable residents Notable past and present residents of the town include: Rev Robert Liston Moderator of the General Assembly of the Church of Scotland in 1787 Geoffrey Keyes, recipient of the Victoria Cross William Wotherspoon, rugby union player Twin cities/towns Corte Franca, Italy (since 31 July 2004) See also Aber and Inver as place-name elements Aberdour Shinty Club List of places in Fife References External links Aberdour Festival website Villages in Fife Parishes in Fife

Abergavenny (; , archaically Abergafenni meaning "mouth of the River Gavenny") is a market town and community in Monmouthshire, Wales. Abergavenny is promoted as a Gateway to Wales; it is approximately from the border with England and is located where the A40 trunk road and the A465 Heads of the Valleys road meet. Originally the site of a Roman fort, Gobannium, it became a medieval walled town within the Welsh Marches. The town contains the remains of a medieval stone castle built soon after the Norman conquest of Wales. Abergavenny is situated at the confluence of the River Usk and a tributary stream, the Gavenny. It is almost entirely surrounded by mountains and hills: the Blorenge (), the Sugar Loaf (), Ysgyryd Fawr (Great Skirrid), Ysgyryd Fach (Little Skirrid), Deri, Rholben and Mynydd Llanwenarth, known locally as "Llanwenarth Breast". Abergavenny provides access to the nearby Black Mountains and the Brecon Beacons National Park. The Marches Way and Beacons Way pass through Abergavenny whilst the Offa's Dyke Path passes through Pandy five miles to the north and the Usk Valley Walk passes through nearby Llanfoist. In the UK 2011 census, the six relevant wards (Lansdown, Grofield, Castle, Croesonen, Cantref and Priory) collectively listed Abergavenny's population as 12,515. The town hosted the 2016 National Eisteddfod of Wales. Etymology The town derives its name from a Brythonic word Gobannia meaning "river of the blacksmiths", and relates to the town's pre-Roman importance in iron smelting. The name is related to the modern Welsh word gof (blacksmith), and so is also associated with the Welsh smith Gofannon from folklore. The river later became, in Welsh, Gafenni, and the town's name became Abergafenni, meaning "mouth of (Welsh: Aber) the Gavenny (Gafenni)". In Welsh, the shortened form Y Fenni may have come into use after about the 15th century, and is now used as the Welsh name. Abergavenny, the English spelling, is in general use. Geography The town originally developed on the high ground to the north of the floodplain of the River Usk and to the west of the valley of the much smaller Gavenny River though has since extended to the east of the latter. It has merged with the originally separate settlement of Mardy to the north but remains separate from that of Llanfoist to the south due to the presence of the river and its floodplain; nevertheless Llanfoist is in many ways a suburb of the town. The ground rises gradually in the north of the town before steepening to form the Deri and Rholben spurs of Sugar Loaf. The A4143 crossing of the Usk by means of the historic Usk Bridge is sited at the narrowest point of the floodplain, a site also chosen for the former crossing of a tramroad and the later mainline railway. The high ground at either side is formed by a legacy of the last ice age, the recessional Llanfoist moraine which underlies both the village which gives it its name, the town centre and the Nevill Hall area. The older parts of the town north of its centre are built upon a relatively flat-lying alluvial fan extending west from the area of St Mary's Priory to Cantref and of similar age to the moraine. In the UK 2011 census, the six relevant wards (Lansdown, Grofield, Castle, Croesonen, Cantref and Priory) collectively listed Abergavenny's population as 12,515. History Roman period Gobannium was a Roman fort guarding the road along the valley of the River Usk, which linked the legionary fortress of Burrium (Usk) and later Isca Augusta or Isca Silurum (Caerleon) in the south with Y Gaer, Brecon and Mid Wales. It was also built to keep the peace among the local British Iron Age tribe, the Silures. Cadw considers that the fort was occupied from around CE50 to CE150. Remains of the walls of this fort were discovered west of the castle when excavating the foundations for a new post office and telephone exchange building in the late 1960s. 11th century Abergavenny grew as a town in early Norman times under the protection of the Baron Bergavenny (or Abergavenny). The first Baron was Hamelin de Balun, from Ballon, a small town with a castle in Maine-Anjou near Le Mans. Today it is in the Sarthe département of France. He founded the Benedictine priory, now the Priory Church of St Mary, in the late 11th century. The Priory belonged originally to the Benedictine foundation of St. Vincent Abbaye at Le Mans. It was subsequently endowed by William de Braose, with a tithe of the profits of the castle and town. The church contains some unique alabaster effigies, church monuments and unique medieval wood carving, such as the Tree of Jesse. 12th and 13th centuries Owing to its geographical location, the town was frequently embroiled in the border warfare and power play of the 12th and 13th centuries in the Welsh Marches. In 1175, Abergavenny Castle was the site of a massacre of Seisyll ap Dyfnwal and his associates by William de Braose, 4th Lord of Bramber. Reference to a market at Abergavenny is found in a charter granted to the Prior by William de Braose. 15th to 17th centuries Owain Glyndŵr attacked Abergavenny in 1404. According to popular legend, his raiders gained access to the walled town with the aid of a local woman who sympathised with the rebellion, letting a small party in via the Market Street gate at midnight. They were able to open the gate and allow a much larger party who set fire to the town and plundered its churches and homes leaving Abergavenny Castle intact. Market Street has been referred to as "Traitors' Lane" thereafter. In 1404 Abergavenny was declared its own nation by Ieuan ab Owain Glyndŵr, illegitimate son of Owain Glyndŵr. The arrangement lasted approximately two weeks. At the Dissolution of the Monasteries in 1541, the priory's endowment went towards the foundation of a free grammar school, King Henry VIII Grammar School, the site itself passing to the Gunter family. During the Civil War, prior to the siege of Raglan Castle in 1645, King Charles I visited Abergavenny and presided in person over the trial of Sir Trefor Williams, 1st Baronet of Llangibby, a Royalist who changed sides, and other Parliamentarians. In 1639, Abergavenny received a charter of incorporation under the title of bailiff and burgesses. A charter with extended privileges was drafted in 1657, but appears never to have been enrolled or to have come into effect. Owing to the refusal of the chief officers of the corporation to take the oath of allegiance to William III in 1688, the charter was annulled, and the town subsequently declined in prosperity. Chapter 28 of the 1535 Act of Henry VIII, which provided that Monmouth, as county town, should return one burgess to Parliament, further stated that other ancient Monmouthshire boroughs were to contribute towards the payment of the member. In consequence of this clause Abergavenny on various occasions shared in the election, the last instance being in 1685. The right to hold two weekly markets and three yearly fairs, beginning in the 13th century, was held ever since as confirmed in 1657. Abergavenny was celebrated for the production of Welsh flannel, and also for the manufacture, whilst the fashion prevailed, of goats' hair periwigs. 19th and 20th centuries Abergavenny railway station, situated south-east of the town centre, opened on 2 January 1854 as part of the Newport, Abergavenny and Hereford Railway. The London North Western Railway sponsored the construction of the railway linking Newport station to Hereford station. The line was taken over by the West Midland Railway in 1860 before becoming part of the Great Western Railway in 1863. A railway line also ran up the valley towards Brynmawr and to Merthyr Tydfil; this was closed during the Beeching cuts in the 1960s and the line to Clydach Gorge is now a cycle track and footpath.

Baron of Abergavenny The title of Baron Abergavenny, in the Nevill family, dates from the 15th century with Edward Nevill, 3rd Baron Bergavenny. From him it has descended continuously, the title being increased to an earldom in 1784; and in 1876 William Nevill 5th Earl, an indefatigable and powerful supporter of the Tory Party, was created 1st Marquess of Abergavenny. Coldbrook Park was a country house in an estate some southeast of the town. The house was originally built in the 14th century and belonged to the Herbert family for many generations until purchased by John Hanbury for his son, the diplomat Sir Charles Hanbury Williams. Sir Charles reconstructed the house in 1746 with the addition of a nine-bay two-storey Georgian façade with a Doric portico. It subsequently passed down in the Hanbury Williams family until it was demolished in 1954.

Welsh language In recent decades the number of Welsh speakers in the town has increased dramatically. The 2001 census recorded 10% of the local population spoke the language, a five-fold increase over ten years from the figure of 2% recorded in 1991. The town has one of the two Welsh-medium primary schools in Monmouthshire, Ysgol Gymraeg y Fenni, which was founded in the early 1990s.

Cattle market A cattle market was held in Abergavenny from 1863 to December 2013. During the period 1825–1863 a sheep market was held at a site in Castle Street, to stop the sale of sheep on the streets of the town. At the time of its closure the market was leased and operated by Abergavenny Market Auctioneers Ltd, who held regular livestock auctions on the site. Market days were held on Tuesdays for the auction sale of finished sheep, cull ewe/store and fodder (hay and straw), and some Fridays for the auction sale of cattle. Following the closure of Newport's cattle market in 2009 for redevelopment, Newport’s sales were held at Abergavenny every Wednesday. In 2011 doubts about the future of Abergavenny Cattle Market were raised following the granting of planning permission by Monmouthshire County Council for its demolition and replacement with a supermarket, car park, and library. In January 2012 the Welsh Government announced the repeal the Abergavenny Improvement Acts of 1854 to 1871 which obliged the holding of a livestock market within the boundaries of Abergavenny town; that repeal being effective from 26 March 2012. Monmouthshire County Council, which requested that the Abergavenny Improvement Acts be repealed, supported plans for a new cattle market to be established about from Abergavenny in countryside at Bryngwyn, some from Raglan. There was local opposition to this site. The new Monmouthshire Livestock Centre, a 27-acre site at Bryngwyn, opened in November 2013.

Adam Carolla (born May 27, 1964) is an American radio personality, comedian, actor and podcaster. He hosts The Adam Carolla Show, a talk show distributed as a podcast which set the record as the "most downloaded podcast" as judged by Guinness World Records in 2011. Carolla co-hosted the syndicated radio call-in program Loveline with Drew Pinsky from 1995 to 2005 as well as the show's television incarnation on MTV from 1996 to 2000. He was the co-host and co-creator of the television program The Man Show (1999–2004), and the co-creator and a regular performer on the television show Crank Yankers (2002–2007, 2019–present). He hosted The Adam Carolla Project, a home improvement television program which aired on TLC in 2005 and The Car Show on Speed in 2011. Carolla has also appeared on the network reality television programs Dancing with the Stars and The Celebrity Apprentice. His book In Fifty Years We'll All Be Chicks debuted on The New York Times Best Seller list in 2010, and his second book, Not Taco Bell Material, also reached The New York Times bestseller status. Carolla has made numerous guest appearances on political talk shows as a commentator. He hosted a weekly segment, "Rollin' with Carolla", on Bill O'Reilly's The O'Reilly Factor. Early life Adam Carolla was born on May 27, 1964, to Jim and Kris (née McCall) Carolla. Some sources list his birthplace as Los Angeles County, California, while others list it as Philadelphia, Pennsylvania. He grew up in the Los Angeles San Fernando Valley, and his parents separated when he was young. Carolla was not given a middle name by his parents; on his driver's license application he listed his middle name as "Lakers" as a joke. The application was processed without notice. His maternal step-grandfather was screenwriter László Görög. Adam was raised in the North Hollywood neighborhood of Los Angeles. He attended Colfax Elementary School, Walter Reed Junior High, and North Hollywood High School. Carolla did not receive his high school diploma until years later as it was held by the school until a library fine was paid. Carolla can be seen paying off the book and receiving his diploma in an episode of his 2005 television show, The Adam Carolla Project. During his youth, Carolla played Pop Warner football for seven years; he later suggested that being involved in sports saved him from a chaotic home life. During his senior year at North Hollywood High School, Carolla distinguished himself in football. In December 1981, he was named to the First Team Offensive Line, Central Valley League, one of 8 leagues at the time in the LA City Section of the California Interscholastic Federation. In October 2020 he spoke of being recruited by "7 or 8" schools including UC-Davis, Cal Poly Pomona, and Cal Poly San Luis Obispo. He began living on his own at the age of 18. He briefly attended Los Angeles Valley College, a community college, where he was placed on academic probation before dropping out to work in a series of jobs, including carpet cleaner, carpenter, boxing instructor, and traffic school instructor. Although broke, Carolla, his friends, and roommates owned a 1963 Cadillac limousine. In the early 1990s, Carolla studied improvisational comedy with The Groundlings and was a member of the ACME Comedy Theatre troupe. Radio In 1994, Carolla volunteered his services as a boxing trainer to prepare Jimmy Kimmel for a bout being staged by KROQ-FM's morning radio program Kevin and Bean. Kimmel was a regular on the show as "Jimmy the Sports Guy" and he was set to fight another KROQ personality in a boxing exhibition which was being billed as the "Bleeda in Reseda". Carolla parlayed this opportunity into a long-running friendship and business partnership with Kimmel as well as a recurring role on Kevin and Bean as cranky woodshop teacher, Mr. Birchum. Loveline In October 1995, after being signed to the William Morris Agency by Mark Itkin, Carolla was offered the job of co-hosting the evening radio call-in show Loveline. His co-hosts were the physician Drew Pinsky ("Dr. Drew") and metal DJ Riki Rachtman. Carolla received the offer after Pinsky heard him on Kevin and Bean (Rachtman left the show the following year.) Loveline was broadcast on KROQ-FM in Los Angeles and was syndicated nationwide on the former Westwood One radio network. While the format of the program was primarily that of a call-in show wherein listeners would ask questions about sex and relationships, Carolla would often spend much of the show ranting about various topics from fart jokes to extended parodies of radio morning shows, including mocking the format's penchant for useless and repetitive weather and traffic reports. In contrast to the reserved, thoughtful Pinsky, Carolla served as the loud, funny side of the show. Carolla's character was described by one reviewer as "a toned-down version of Howard Stern minus the huge ego". In a late-2003 Loveline episode, Carolla said that Hawaiians are "dumb", "in-bred", "retarded" people who are among the "dumbest people we have". The comments were met with anger in Hawaii and resulted in Lovelines cancellation on Hawaiian affiliate KPOI. The Adam Carolla Show In October 2005, Carolla was announced as the host of a new morning radio show on the Infinity Broadcasting network. His new show would replace the popular syndicated Howard Stern Show (which was moving to satellite radio) in twelve of the 27 markets in which Stern had been broadcast including Los Angeles, Las Vegas, San Francisco, San Diego, Phoenix, and Portland, Oregon. The Adam Carolla Show debuted in January 2006. In early 2008, actor Gerard Butler sat in and observed Adam Carolla on The Adam Carolla Show in order to prepare for his role in The Ugly Truth as a cynical and crass talk-radio host allegedly based on Carolla. On February 18, 2009, The Adam Carolla Show was canceled as part of a format switch at KLSX to AMP FM, a new top 40 station. The final show was Friday, February 20, 2009. Podcasts The Adam Carolla Podcast Carolla started a daily podcast on February 23, 2009, at his personal website, which would evolve into the ACE Broadcasting Network. The first Adam Carolla podcast was downloaded more than 250,000 times in the initial 24 hours, and by the third podcast, it was the number one podcast on iTunes in both the U.S. and Canada. During the debut week, the Adam Carolla podcast recorded 1.6 million downloads. In the second week it recorded 2.4 million downloads. By the fourth episode of the second week, featuring former Adam Carolla Show sidekick Dave Dameshek, the show was downloaded more than 500,000 times. Adam stated that bandwidth cost more than $9,000 a month as of May 2009. At the end of 2009, The Adam Carolla Podcast was selected by iTunes for its end-of-the-year awards as the Best Audio Podcast of 2009. On the April 4, 2010, episode of The Adam Carolla Show, Carolla referred to Filipino boxer Manny Pacquiao as a "fucking idiot" and said of the Philippines: "They got this and sex tours, that's all they have over there. Get your shit together, Philippines." A spokesman for President Gloria Macapagal Arroyo called Carolla an "ignorant fool". Carolla subsequently apologized via Twitter. On May 18, 2011, Carolla noted on Jimmy Kimmel Live! that The Adam Carolla Show had taken the Guinness World Record for the most downloaded podcast ever from previous holder Ricky Gervais by receiving 59,574,843 unique downloads from March 2009 to March 16, 2011. In 2010, Carolla posed for the NOH8 Campaign. In August 2011, Carolla released a podcast where he mocked a petition to the producers of Sesame Street that demanded Bert and Ernie get married on air. He said on air that gay activists should "[j]ust get married, and please shut up" and that "Y.U.C.K." would be more memorable acronym than LGBT, and referring to transgender people he asked: "When did we start giving a shit about these people?" GLAAD characterized the previous remarks by Carolla as offensive, including an assertion that "all things being equal", heterosexual parents make better parents than homosexual parents. Carolla responded: "I'm sorry my comments were hurtful. I'm a comedian, not a politician." "Patent Troll" Lawsuit In 2013, Personal Audio filed a patent infringement lawsuit against Lotzi Digital, Inc., producers of The Adam Carolla Show and several other podcasts on the Carolla Digital Network, in the U.S. District Court for the Eastern District of Texas. The suit alleged that owner Adam Carolla and his network of content infringed on Personal Audio's patent 8,112,504. Using the crowdfunding site FundAnything.com, listeners contributed more than $475,000 (as of August 2014) to support Carolla throughout the legal proceedings. Personal Audio dropped the lawsuit July 29, 2014, stating that the defendants were not "making significant money from infringing Personal Audio's patents". However, Carolla countersued, having already spent hundreds of thousands of dollars mounting a defense against claims he deemed unfounded. Among claims sought by the countersuit was a request that the initial patent be invalidated. On August 15, 2014, Carolla and Personal Audio filed a joint motion to dismiss after reaching a settlement, the details of which were not made public but included a six-week "quiet period" during which neither party could speak to the media. Both parties' claims were dropped without prejudice and, as such, could be refiled at a later date. Television 1996 through 2004 From 1996 to 2000, Carolla and Dr. Drew hosted Loveline on MTV, a television version of the radio show. Carolla began his first original television series with The Man Show, along with partner and friend Jimmy Kimmel, on Comedy Central from 1999 to 2003. He left The Man Show at the same time as Kimmel. Carolla has continued his work with Kimmel as a writer and guest on Jimmy Kimmel Live!. He also appeared on an episode of Space Ghost Coast to Coast around this time. Carolla and partner Daniel Kellison are the heads of Jackhole Productions. The two created the television show Crank Yankers for Comedy Central, which revived the Mr. Birchum character. The show premiered in 2002 on Comedy Central and returned to MTV2 on February 9, 2007, running again until March 30, 2007. The show screened in Australia on SBS Television and The Comedy Channel between 2003 and 2008.

Dancing with the Stars performances On June 16, 2008, Carolla was selected to host a pilot of an American version of the popular BBC show Top Gear for NBC. In December 2008, NBC decided not to pick up the show. 2009 to present On February 21, 2009, a day after his Los Angeles-based morning radio show was canceled – as part of a format change at KLSX-FM – CBS ordered a comedy pilot, Ace in the Hole, starring Carolla as a husband and father who works as a driving instructor. Carolla created and wrote the pilot with Kevin Hench (Jimmy Kimmel Live!). Carolla stated that Pamela Adlon was to play his wife and Windell Middlebrooks would play his best friend. During his March 30, 2009, podcast, Carolla briefly described the show as being "All in the Family, essentially", with Carolla playing a similar role to that of Archie Bunker. On the July 23, 2009, episode of the Adam Carolla Podcast, Carolla announced that CBS was not picking up the pilot for the 2009 season, "in any way, shape or form". On October 22, 2009, it was reported in Variety that Carolla had struck a deal with NBC to produce a half-hour pilot for a sitcom. The report was later confirmed on January 4, 2010, and was the first comedy pilot ordered by NBC for the season. The untitled project, written by Carolla and Kevin Hench, was a single-camera sitcom that starred Carolla as a contractor and father who attempts to rebuild his life after his wife leaves him.

Premiering on February 19, 2012, Carolla was also one of the contestants in the 12th season of NBC's The Celebrity Apprentice.

In 2017, Carolla and Dennis Prager began filming No Safe Spaces, a documentary about political correctness at universities. No Safe Spaces had a limited opening on October 25, 2019, and did well enough to open nationwide on December 6, 2019. Filmography Books Carolla and Drew Pinsky co-wrote (with Marshall Fine) the self-help book The Dr. Drew and Adam Book: A Survival Guide to Life and Love, published in 1998. The book is a compilation of some of the advice the pair compiled while producing Loveline. In November 2010, Carolla's In Fifty Years We'll All Be Chicks... And Other Complaints from an Angry Middle-Aged White Guy was published by Crown Archetype and debuted at number eight on The New York Times Best Seller list for hardcover non-fiction on November 21, 2010. The book was compiled from rants Carolla had delivered on his radio show and podcast along with some new material and was dictated to and ghost-written by Mike Lynch. Carolla published a short, illustrated e-book entitled Rich Man, Poor Man in January 2012. The book details some similarities in the experiences of the very rich and the very poor which are not shared by the middle class. The book was illustrated by Michael Narren. Carolla's book Not Taco Bell Material was published by Crown Archetype on June 12, 2012. In President Me: The America That's in My Head, Carolla presents the comedian's fantasy of the United States with him at the helm. When asked in separate interviews, both before and after the book's release, about whether the "if-I-were-king" critique of America was a serious piece, he said it's both: "Well, there's a lot of jokes in it, but you know, it's like... Well, if you have a fat friend you may make a lot of fat jokes about your fat friend, but he's still fat". In Daddy, Stop Talking!: And Other Things My Kids Want But Won't Be Getting, Carolla writes about modern parenting. Carolla describes what he believes adults must do if they don't want to have to support their kids forever. Carolla uses his own childhood as a cautionary tale, and decries helicopter parenting. Carolla's book, I'm Your Emotional Support Animal: Navigating Our All Woke, No Joke Culture, was published by Post Hill Press on June 16, 2020. Carolla's latest book, Everything Reminds Me of Something, was published by Post Hill Press on July 19, 2022. Views Religious Carolla is an atheist. Political Regarding his political views, Carolla has stated, "I guess I would be Republican, in the sense that I want a secure border, I'm not into the welfare state, I'm not into all those freebie lunch programs. It just kind of demeans people." He goes on to state, however, that he is also in favor of typically liberal causes such as the legalization of marijuana (he is a member of the advisory board of the Marijuana Policy Project) and support for some progressive causes such as "[being] against semi-automatic and automatic weapons. I'm not an NRA guy by any stretch of the imagination. I'd like alternative energy to be explored and electric cars to be used, but I want them to be powered by nuclear power plants." Elsewhere, he has stated, "My feeling is this whole country is founded on the principle of 'If you are not hurting anyone, and you're not fucking with someone else's shit, and you are paying your taxes, you should be able to just do what you want to do.' It's the freedom and the independence." In an interview with Reason TV, Carolla described his views as libertarian. Carolla expressed his support for Andrew Yang's 2020 presidential run. Women and comedy In June 2012, Carolla gave a printed interview to the New York Post, where among other things he stated that "chicks" are "always the least funny on the writing staff" and that "dudes are funnier than chicks". Carolla's comments were criticized as sexist. Carolla criticized coverage of his comments as over-simplistic and misleading. Cancel culture Carolla said, "If you meet anyone over 45, they'll tell you they got paddled, they got swatted, the teacher would smack them with a ruler. … Paddling a kid sounds pretty outrageous in 2020 and nobody would stand for it. ... But the people who engaged in it at the time when it was common practice or had a context, we don't need to build a time machine so we can cancel-culture them". In an interview with Tucker Carlson, Carolla said that cancel culture is "destroying free speech and killing comedy." Personal life On September 28, 2002, Carolla married Lynette Paradise. The couple's twins Natalia and Santino "Sonny" Richard Carolla were born June 7, 2006. Carolla announced in May 2021 that he and Lynette were divorcing after 19 years. He currently lives in La Cañada Flintridge, California. Carolla was a part owner of Amalfi, an Italian restaurant in Los Angeles, saying, "I own about two percent of it, but I've never seen a penny." Carolla won the 2013 Pro/Celebrity Race as a professional and the 2012 Pro/Celebrity Race at the Toyota Grand Prix of Long Beach as an amateur. The 2012 race was run on April 14, 2012, and was broadcast on Speed TV. Carolla has previously participated in the race in 2010 and 2003. He finished ninth among 19 racers (fifth among the ten celebrities) in 2010 despite being regarded as a pre-race favorite. He is also a serious automobile collector with over 20 cars. His collection includes several Lamborghinis from the 1960s and early 1970s, including two Miuras (of 764 examples ever produced), one of which he has loaned to the Petersen Automotive Museum in Los Angeles, two 400GT 2+2s (of 247 units produced) and a 1965 350GT (one of 135 built). At least one Ferrari, an Aston Martin, and several vintage race cars round out the collection. Honors Carolla and Drew Pinsky received a Sexual Health in Entertainment (SHINE) Award from The Media Project in 2000 for "incorporating accurate and honest portrayals of sexuality" in the talk show category for Loveline. Asteroid (4535) Adamcarolla is named in his honor.

Autocorrelation, sometimes known as serial correlation in the discrete time case, is the correlation of a signal with a delayed copy of itself as a function of delay. Informally, it is the similarity between observations of a random variable as a function of the time lag between them. The analysis of autocorrelation is a mathematical tool for finding repeating patterns, such as the presence of a periodic signal obscured by noise, or identifying the missing fundamental frequency in a signal implied by its harmonic frequencies. It is often used in signal processing for analyzing functions or series of values, such as time domain signals. Different fields of study define autocorrelation differently, and not all of these definitions are equivalent. In some fields, the term is used interchangeably with autocovariance. Unit root processes, trend-stationary processes, autoregressive processes, and moving average processes are specific forms of processes with autocorrelation. Auto-correlation of stochastic processes In statistics, the autocorrelation of a real or complex random process is the Pearson correlation between values of the process at different times, as a function of the two times or of the time lag. Let be a random process, and be any point in time ( may be an integer for a discrete-time process or a real number for a continuous-time process). Then is the value (or realization) produced by a given run of the process at time . Suppose that the process has mean and variance at time , for each . Then the definition of the auto-correlation function between times and is where is the expected value operator and the bar represents complex conjugation. Note that the expectation may not be well defined. Subtracting the mean before multiplication yields the auto-covariance function between times and : Note that this expression is not well defined for all time series or processes, because the mean may not exist, or the variance may be zero (for a constant process) or infinite (for processes with distribution lacking well-behaved moments, such as certain types of power law). Definition for wide-sense stationary stochastic process If is a wide-sense stationary process then the mean and the variance are time-independent, and further the autocovariance function depends only on the lag between and : the autocovariance depends only on the time-distance between the pair of values but not on their position in time. This further implies that the autocovariance and auto-correlation can be expressed as a function of the time-lag, and that this would be an even function of the lag . This gives the more familiar forms for the auto-correlation function and the auto-covariance function: In particular, note that Normalization It is common practice in some disciplines (e.g. statistics and time series analysis) to normalize the autocovariance function to get a time-dependent Pearson correlation coefficient. However, in other disciplines (e.g. engineering) the normalization is usually dropped and the terms "autocorrelation" and "autocovariance" are used interchangeably. The definition of the auto-correlation coefficient of a stochastic process is If the function is well defined, its value must lie in the range , with 1 indicating perfect correlation and −1 indicating perfect anti-correlation. For a wide-sense stationary (WSS) process, the definition is . The normalization is important both because the interpretation of the autocorrelation as a correlation provides a scale-free measure of the strength of statistical dependence, and because the normalization has an effect on the statistical properties of the estimated autocorrelations. Properties Symmetry property The fact that the auto-correlation function is an even function can be stated as respectively for a WSS process: Maximum at zero For a WSS process: Notice that is always real. Cauchy–Schwarz inequality The Cauchy–Schwarz inequality, inequality for stochastic processes: Autocorrelation of white noise The autocorrelation of a continuous-time white noise signal will have a strong peak (represented by a Dirac delta function) at and will be exactly for all other . Wiener–Khinchin theorem The Wiener–Khinchin theorem relates the autocorrelation function to the power spectral density via the Fourier transform: For real-valued functions, the symmetric autocorrelation function has a real symmetric transform, so the Wiener–Khinchin theorem can be re-expressed in terms of real cosines only: Auto-correlation of random vectors The (potentially time-dependent) auto-correlation matrix (also called second moment) of a (potentially time-dependent) random vector is an matrix containing as elements the autocorrelations of all pairs of elements of the random vector . The autocorrelation matrix is used in various digital signal processing algorithms. For a random vector containing random elements whose expected value and variance exist, the auto-correlation matrix is defined by where denotes the transposed matrix of dimensions . Written component-wise: If is a complex random vector, the autocorrelation matrix is instead defined by Here denotes Hermitian transpose. For example, if is a random vector, then is a matrix whose -th entry is . Properties of the autocorrelation matrix The autocorrelation matrix is a Hermitian matrix for complex random vectors and a symmetric matrix for real random vectors. The autocorrelation matrix is a positive semidefinite matrix, i.e. for a real random vector, and respectively in case of a complex random vector. All eigenvalues of the autocorrelation matrix are real and non-negative. The auto-covariance matrix is related to the autocorrelation matrix as follows:Respectively for complex random vectors: Auto-correlation of deterministic signals In signal processing, the above definition is often used without the normalization, that is, without subtracting the mean and dividing by the variance. When the autocorrelation function is normalized by mean and variance, it is sometimes referred to as the autocorrelation coefficient or autocovariance function. Auto-correlation of continuous-time signal Given a signal , the continuous autocorrelation is most often defined as the continuous cross-correlation integral of with itself, at lag . where represents the complex conjugate of . Note that the parameter in the integral is a dummy variable and is only necessary to calculate the integral. It has no specific meaning. Auto-correlation of discrete-time signal The discrete autocorrelation at lag for a discrete-time signal is The above definitions work for signals that are square integrable, or square summable, that is, of finite energy. Signals that "last forever" are treated instead as random processes, in which case different definitions are needed, based on expected values. For wide-sense-stationary random processes, the autocorrelations are defined as For processes that are not stationary, these will also be functions of , or . For processes that are also ergodic, the expectation can be replaced by the limit of a time average. The autocorrelation of an ergodic process is sometimes defined as or equated to These definitions have the advantage that they give sensible well-defined single-parameter results for periodic functions, even when those functions are not the output of stationary ergodic processes. Alternatively, signals that last forever can be treated by a short-time autocorrelation function analysis, using finite time integrals. (See short-time Fourier transform for a related process.) Definition for periodic signals If is a continuous periodic function of period , the integration from to is replaced by integration over any interval of length : which is equivalent to Properties In the following, we will describe properties of one-dimensional autocorrelations only, since most properties are easily transferred from the one-dimensional case to the multi-dimensional cases. These properties hold for wide-sense stationary processes. A fundamental property of the autocorrelation is symmetry, , which is easy to prove from the definition. In the continuous case, the autocorrelation is an even function when is a real function, and the autocorrelation is a Hermitian function when is a complex function. The continuous autocorrelation function reaches its peak at the origin, where it takes a real value, i.e. for any delay , . This is a consequence of the rearrangement inequality. The same result holds in the discrete case. The autocorrelation of a periodic function is, itself, periodic with the same period. The autocorrelation of the sum of two completely uncorrelated functions (the cross-correlation is zero for all ) is the sum of the autocorrelations of each function separately. Since autocorrelation is a specific type of cross-correlation, it maintains all the properties of cross-correlation. By using the symbol to represent convolution and is a function which manipulates the function and is defined as , the definition for may be written as: Multi-dimensional autocorrelation Multi-dimensional autocorrelation is defined similarly. For example, in three dimensions the autocorrelation of a square-summable discrete signal would be When mean values are subtracted from signals before computing an autocorrelation function, the resulting function is usually called an auto-covariance function. Efficient computation For data expressed as a discrete sequence, it is frequently necessary to compute the autocorrelation with high computational efficiency. A brute force method based on the signal processing definition can be used when the signal size is small. For example, to calculate the autocorrelation of the real signal sequence (i.e. , and for all other values of ) by hand, we first recognize that the definition just given is the same as the "usual" multiplication, but with right shifts, where each vertical addition gives the autocorrelation for particular lag values: Thus the required autocorrelation sequence is , where and the autocorrelation for other lag values being zero. In this calculation we do not perform the carry-over operation during addition as is usual in normal multiplication. Note that we can halve the number of operations required by exploiting the inherent symmetry of the autocorrelation. If the signal happens to be periodic, i.e. then we get a circular autocorrelation (similar to circular convolution) where the left and right tails of the previous autocorrelation sequence will overlap and give which has the same period as the signal sequence The procedure can be regarded as an application of the convolution property of Z-transform of a discrete signal. While the brute force algorithm is order , several efficient algorithms exist which can compute the autocorrelation in order . For example, the Wiener–Khinchin theorem allows computing the autocorrelation from the raw data with two fast Fourier transforms (FFT): where IFFT denotes the inverse fast Fourier transform. The asterisk denotes complex conjugate. Alternatively, a multiple correlation can be performed by using brute force calculation for low values, and then progressively binning the data with a logarithmic density to compute higher values, resulting in the same efficiency, but with lower memory requirements. Estimation For a discrete process with known mean and variance for which we observe observations , an estimate of the autocorrelation coefficient may be obtained as for any positive integer . When the true mean and variance are known, this estimate is unbiased. If the true mean and variance of the process are not known there are several possibilities: If and are replaced by the standard formulae for sample mean and sample variance, then this is a biased estimate. A periodogram-based estimate replaces in the above formula with . This estimate is always biased; however, it usually has a smaller mean squared error. Other possibilities derive from treating the two portions of data and separately and calculating separate sample means and/or sample variances for use in defining the estimate. The advantage of estimates of the last type is that the set of estimated autocorrelations, as a function of , then form a function which is a valid autocorrelation in the sense that it is possible to define a theoretical process having exactly that autocorrelation. Other estimates can suffer from the problem that, if they are used to calculate the variance of a linear combination of the 's, the variance calculated may turn out to be negative. Regression analysis In regression analysis using time series data, autocorrelation in a variable of interest is typically modeled either with an autoregressive model (AR), a moving average model (MA), their combination as an autoregressive-moving-average model (ARMA), or an extension of the latter called an autoregressive integrated moving average model (ARIMA). With multiple interrelated data series, vector autoregression (VAR) or its extensions are used. In ordinary least squares (OLS), the adequacy of a model specification can be checked in part by establishing whether there is autocorrelation of the regression residuals. Problematic autocorrelation of the errors, which themselves are unobserved, can generally be detected because it produces autocorrelation in the observable residuals. (Errors are also known as "error terms" in econometrics.) Autocorrelation of the errors violates the ordinary least squares assumption that the error terms are uncorrelated, meaning that the Gauss Markov theorem does not apply, and that OLS estimators are no longer the Best Linear Unbiased Estimators (BLUE). While it does not bias the OLS coefficient estimates, the standard errors tend to be underestimated (and the t-scores overestimated) when the autocorrelations of the errors at low lags are positive. The traditional test for the presence of first-order autocorrelation is the Durbin–Watson statistic or, if the explanatory variables include a lagged dependent variable, Durbin's h statistic. The Durbin-Watson can be linearly mapped however to the Pearson correlation between values and their lags. A more flexible test, covering autocorrelation of higher orders and applicable whether or not the regressors include lags of the dependent variable, is the Breusch–Godfrey test. This involves an auxiliary regression, wherein the residuals obtained from estimating the model of interest are regressed on (a) the original regressors and (b) k lags of the residuals, where 'k' is the order of the test. The simplest version of the test statistic from this auxiliary regression is TR2, where T is the sample size and R2 is the coefficient of determination. Under the null hypothesis of no autocorrelation, this statistic is asymptotically distributed as with k degrees of freedom. Responses to nonzero autocorrelation include generalized least squares and the Newey–West HAC estimator (Heteroskedasticity and Autocorrelation Consistent). In the estimation of a moving average model (MA), the autocorrelation function is used to determine the appropriate number of lagged error terms to be included. This is based on the fact that for an MA process of order q, we have , for , and , for . Applications Autocorrelation analysis is used heavily in fluorescence correlation spectroscopy to provide quantitative insight into molecular-level diffusion and chemical reactions. Another application of autocorrelation is the measurement of optical spectra and the measurement of very-short-duration light pulses produced by lasers, both using optical autocorrelators. Autocorrelation is used to analyze dynamic light scattering data, which notably enables determination of the particle size distributions of nanometer-sized particles or micelles suspended in a fluid. A laser shining into the mixture produces a speckle pattern that results from the motion of the particles. Autocorrelation of the signal can be analyzed in terms of the diffusion of the particles. From this, knowing the viscosity of the fluid, the sizes of the particles can be calculated. Utilized in the GPS system to correct for the propagation delay, or time shift, between the point of time at the transmission of the carrier signal at the satellites, and the point of time at the receiver on the ground. This is done by the receiver generating a replica signal of the 1,023-bit C/A (Coarse/Acquisition) code, and generating lines of code chips [-1,1] in packets of ten at a time, or 10,230 chips (1,023 × 10), shifting slightly as it goes along in order to accommodate for the doppler shift in the incoming satellite signal, until the receiver replica signal and the satellite signal codes match up. The small-angle X-ray scattering intensity of a nanostructured system is the Fourier transform of the spatial autocorrelation function of the electron density. In surface science and scanning probe microscopy, autocorrelation is used to establish a link between surface morphology and functional characteristics. In optics, normalized autocorrelations and cross-correlations give the degree of coherence of an electromagnetic field. In signal processing, autocorrelation can give information about repeating events like musical beats (for example, to determine tempo) or pulsar frequencies, though it cannot tell the position in time of the beat. It can also be used to estimate the pitch of a musical tone. In music recording, autocorrelation is used as a pitch detection algorithm prior to vocal processing, as a distortion effect or to eliminate undesired mistakes and inaccuracies. Autocorrelation in space rather than time, via the Patterson function, is used by X-ray diffractionists to help recover the "Fourier phase information" on atom positions not available through diffraction alone. In statistics, spatial autocorrelation between sample locations also helps one estimate mean value uncertainties when sampling a heterogeneous population. The SEQUEST algorithm for analyzing mass spectra makes use of autocorrelation in conjunction with cross-correlation to score the similarity of an observed spectrum to an idealized spectrum representing a peptide. In astrophysics, autocorrelation is used to study and characterize the spatial distribution of galaxies in the universe and in multi-wavelength observations of low mass X-ray binaries. In panel data, spatial autocorrelation refers to correlation of a variable with itself through space. In analysis of Markov chain Monte Carlo data, autocorrelation must be taken into account for correct error determination. In geosciences (specifically in geophysics) it can be used to compute an autocorrelation seismic attribute, out of a 3D seismic survey of the underground. In medical ultrasound imaging, autocorrelation is used to visualize blood flow. In intertemporal portfolio choice, the presence or absence of autocorrelation in an asset's rate of return can affect the optimal portion of the portfolio to hold in that asset. Autocorrelation has been used to accurately measure power system frequency in numerical relays. Serial dependence Serial dependence is closely linked to the notion of autocorrelation, but represents a distinct concept (see Correlation and dependence). In particular, it is possible to have serial dependence but no (linear) correlation. In some fields however, the two terms are used as synonyms. A time series of a random variable has serial dependence if the value at some time in the series is statistically dependent on the value at another time . A series is serially independent if there is no dependence between any pair. If a time series is stationary, then statistical dependence between the pair would imply that there is statistical dependence between all pairs of values at the same lag .

Andalusia (, ; ) is the southernmost autonomous community in Peninsular Spain. Andalusia is located in the south of the Iberian Peninsula, in southwestern Europe. It is the most populous and the second-largest autonomous community in the country. It is officially recognised as a historical nationality and a national reality. The territory is divided into eight provinces: Almería, Cádiz, Córdoba, Granada, Huelva, Jaén, Málaga, and Seville. Its capital city is Seville. The seat of the High Court of Justice of Andalusia is located in the city of Granada. Andalusia is immediately south of the autonomous communities of Extremadura and Castilla-La Mancha; west of the autonomous community of Murcia and the Mediterranean Sea; east of Portugal and the Atlantic Ocean; and north of the Mediterranean Sea and the Strait of Gibraltar. Gibraltar shares a land border with the Andalusian portion of the province of Cádiz at the eastern end of the Strait of Gibraltar. The main mountain ranges of Andalusia are the Sierra Morena and the Baetic System, consisting of the Subbaetic and Penibaetic Mountains, separated by the Intrabaetic Basin. In the north, the Sierra Morena separates Andalusia from the plains of Extremadura and Castile–La Mancha on Spain's Meseta Central. To the south, the geographic subregion of lies mostly within the Baetic System, while is in the Baetic Depression of the valley of the Guadalquivir. The name "Andalusia" is derived from the Arabic word Al-Andalus (الأندلس), which in turn may be derived from the Vandals, the Goths or pre-Roman Iberian tribes. The toponym al-Andalus is first attested by inscriptions on coins minted in 716 by the new Muslim government of Iberia. These coins, called dinars, were inscribed in both Latin and Arabic. The region's history and culture have been influenced by the Tartessians, Iberians, Phoenicians, Carthaginians, Greeks, Romans, Vandals, Visigoths, Byzantines, Berbers, Arabs, Jews, Romanis and Castilians. During the Islamic Golden Age, Córdoba surpassed Constantinople to be Europe's biggest city, and became the capital of Al-Andalus and a prominent center of education and learning in the world, producing numerous philosophers and scientists. The Crown of Castile conquered and settled the Guadalquivir Valley in the 13th century. The mountainous eastern part of the region (the Kingdom of Granada) was subdued in the late 15th century. Atlantic-facing harbors prospered upon trade with the New World. Chronic inequalities in the social structure caused by uneven distribution of land property in large estates induced recurring episodes of upheaval and social unrest in the agrarian sector in the 19th and 20th centuries. Andalusia has historically been an agricultural region, compared to the rest of Spain and the rest of Europe. Still, the growth of the community in the sectors of industry and services was above average in Spain and higher than many communities in the Eurozone. The region has a rich culture and a strong identity. Many cultural phenomena that are seen internationally as distinctively Spanish are largely or entirely Andalusian in origin. These include flamenco and, to a lesser extent, bullfighting and Hispano-Moorish architectural styles, both of which are also prevalent in some other regions of Spain. Andalusia's hinterland is the hottest area of Europe, with Córdoba and Seville averaging above in summer high temperatures. These high temperatures, typical of the Guadalquivir valley (and other valleys in southern Iberia) are usually reached between 5 p.m. and 9 p.m. (local time), tempered by sea and mountain breezes afterwards. However, during heat waves late evening temperatures can locally stay around until close to midnight, and daytime highs of over are common. Also, Seville is the warmest city in continental Europe with average annual temperature of . Name Its present form is derived from the Arabic name for Muslim Iberia, "Al-Andalus". The etymology of the name "Al-Andalus" is disputed, and the extent of Iberian territory encompassed by the name has changed over the centuries. Traditionally it has been assumed to be derived from the name of the Vandals. Since the 1980s, a number of proposals have challenged this contention. Halm, in 1989, derived the name from a Gothic term, *, and in 2002, Bossong suggested its derivation from a pre-Roman substrate. The Spanish place name Andalucía (immediate source of the English Andalusia) was introduced into the Spanish languages in the 13th century under the form el Andalucía. The name was adopted to refer to those territories still under Moorish rule, and generally south of Castilla Nueva and Valencia, and corresponding with the former Roman province hitherto called Baetica in Latin sources. This was a Castilianization of Al-Andalusiya, the adjectival form of the Arabic language al-Andalus, the name given by the Arabs to all of the Iberian territories under Muslim rule from 711 to 1492. The etymology of al-Andalus is itself somewhat debated (see al-Andalus), but in fact it entered the Arabic language before this area came under Moorish rule. Like the Arabic term al-Andalus, in historical contexts the Spanish term Andalucía or the English term Andalusia do not necessarily refer to the exact territory designated by these terms today. Initially, the term referred exclusively to territories under Muslim control. Later, it was applied to some of the last Iberian territories to be regained from the Muslims, though not always to exactly the same ones. In the Estoria de España (also known as the Primera Crónica General) of Alfonso X of Castile, written in the second half of the 13th century, the term Andalucía is used with three different meanings: As a literal translation of the Arabic al-Ándalus when Arabic texts are quoted. To designate the territories the Christians had regained by that time in the Guadalquivir valley and in the Kingdoms of Granada and Murcia. In a document from 1253, Alfonso X styled himself Rey de Castilla, León y de toda Andalucía ("King of Castile, León and all of Andalusia"). To designate the territories the Christians had regained by that time in the Guadalquivir valley until that date (the Kingdoms of Jaén, Córdoba and Seville – the Kingdom of Granada was incorporated in 1492). This was the most common significance in the Late Middle Ages and Early modern period. From an administrative point of view, Granada remained separate for many years even after the completion of the Reconquista due, above all, to its emblematic character as the last territory regained, and as the seat of the important Real Chancillería de Granada, a court of last resort. Still, the reconquest and repopulation of Granada was accomplished largely by people from the three preexisting Christian kingdoms of Andalusia, and Granada came to be considered a fourth kingdom of Andalusia. The often-used expression "Four Kingdoms of Andalusia" dates back in Spanish at least to the mid-18th century. Symbols The Andalusian emblem shows the figure of Hercules and two lions between the two pillars of Hercules that tradition situates on either side of the Strait of Gibraltar. An inscription below, superimposed on an image of the flag of Andalusia reads Andalucía por sí, para España y la Humanidad ("Andalusia for herself, Spain and Humanity"). Over the two columns is a semicircular arch in the colours of the flag of Andalusia, with the Latin words Dominator Hercules Fundator (Lord Hercules is the Founder) superimposed. The official flag of Andalusia consists of three equal horizontal stripes, coloured green, white, and green respectively; the Andalusian coat of arms is superimposed on the central stripe. Its design was overseen by Blas Infante and approved in the Assembly of Ronda (a 1918 gathering of Andalusian nationalists at Ronda). Blas Infante considered these to have been the colours most used in regional symbols throughout the region's history. According to him, the green came in particular from the standard of the Umayyad Caliphate and represented the call for a gathering of the populace. The white symbolised pardon in the Almohad dynasty, interpreted in European heraldry as parliament or peace. Other writers have justified the colours differently, with some Andalusian nationalists referring to them as the Arbonaida, meaning white-and-green in Mozarabic, a Romance language that was spoken in the region in Muslim times. Nowadays, the Andalusian government states that the colours of the flag evoke the Andalusian landscape as well as values of purity and hope for the future. The anthem of Andalusia was composed by José del Castillo Díaz (director of the Municipal Band of Seville, commonly known as Maestro Castillo) with lyrics by Blas Infante. The music was inspired by Santo Dios, a popular religious song sung at harvest time by peasants and day labourers in the provinces of Málaga, Seville, and Huelva. Blas Infante brought the song to Maestro Castillo's attention; Maestro Castillo adapted and harmonized the traditional melody. The lyrics appeal to the Andalusians to mobilise and demand tierra y libertad ("land and liberty") by way of agrarian reform and a statute of autonomy within Spain. The Parliament of Andalusia voted unanimously in 1983 that the preamble to the Statute of Autonomy recognise Blas Infante as the Father of the Andalusian Nation (Padre de la Patria Andaluza), which was reaffirmed in the reformed Statute of Autonomy submitted to popular referendum 18 February 2007. The preamble of the present 2007 Statute of Autonomy says that Article 2 of the present Spanish Constitution of 1978 recognises Andalusia as a nationality. Later, in its articulation, it speaks of Andalusia as a "historic nationality" (Spanish: nacionalidad histórica). It also cites the 1919 Andalusianist Manifesto of Córdoba describing Andalusia as a "national reality" (realidad nacional), but does not endorse that formulation. Article 1 of the earlier 1981 Statute of Autonomy defined it simply as a "nationality" (nacionalidad). The national holiday, Andalusia Day, is celebrated on 28 February, commemorating the 1980 autonomy referendum. The honorific title of Hijo Predilecto de Andalucía ("Favourite Son of Andalusia") is granted by the Autonomous Government of Andalusia to those whose exceptional merits benefited Andalusia, for work or achievements in natural, social, or political science. It is the highest distinction given by the Autonomous Community of Andalusia. Geography The Sevillian historian Antonio Domínguez Ortiz wrote that: Location Andalusia has a surface area of , 17.3% of the territory of Spain. Andalusia alone is comparable in extent and in the variety of its terrain to any of several of the smaller European countries. To the east is the Mediterranean Sea; to the west Portugal and the Gulf of Cádiz (Atlantic Ocean); to the north the Sierra Morena constitutes the border with the Meseta Central; to the south, the self-governing British overseas territory of Gibraltar and the Strait of Gibraltar separate it from Morocco. Climate Andalusia is home to the hottest and driest climates in Spain, with yearly average rainfall around in Cabo de Gata, as well as some of the wettest ones, with yearly average rainfall above in inland Cádiz. In the west, weather systems sweeping in from the Atlantic ensure that it is relatively wet and humid in the winter, with some areas receiving copious amounts. Contrary to what many people think, as a whole, the region enjoys above-average yearly rainfall in the context of Spain. Andalusia sits at a latitude between 36° and 38° 44' N, in the warm-temperate region. In general, it experiences a hot-summer Mediterranean climate, with dry summers influenced by the Azores High, but subject to occasional torrential rains and extremely hot temperatures. In the winter, the tropical anticyclones move south, allowing cold polar fronts to penetrate the region. Still, within Andalusia there is considerable climatic variety. From the extensive coastal plains one may pass to the valley of the Guadalquivir, barely above sea level, then to the highest altitudes in the Iberian peninsula in the peaks of the Sierra Nevada. In a mere one can pass from the subtropical coast of the province of Granada to the snowy peaks of Mulhacén. Andalusia also includes both the dry Tabernas Desert in the province of Almería and the Sierra de Grazalema Natural Park in the province of Cádiz, which experiences Spain's greatest rainfall. Annual rainfall in the Sierra de Grazalema has been measured as high as in 1963, the highest ever recorded for any location in Iberia. Andalusia is also home to the driest place in continental Europe, the Cabo de Gata, with only of rain per year. In general, as one goes from west to east, away from the Atlantic, there is less precipitation. "Wet Andalusia" includes most of the highest points in the region, above all the Sierra de Grazalema but also the Serranía de Ronda in western Málaga. The valley of the Guadalquivir has moderate rainfall. The Tabernas Desert in Almería, Europe's only true desert, has less than 75 days with any measurable precipitation, and some particular places in the desert have as few as 50 such days. Much of "dry Andalusia" has more than 300 sunny days a year. The average temperature in Andalusia throughout the year is over . Averages in the cities range from in Baeza to in Almería. Much of the Guadalquivir valley and the Mediterranean coast has an average of about . The coldest month is January when Granada at the foot of the Sierra Nevada experiences an average temperature of . The hottest are July and August, with an average temperature of for Andalusia as a whole. Córdoba is the hottest provincial capital, followed by Seville. The Guadalquivir valley has experienced some of the highest temperatures recorded in Europe, with a maximum of recorded at Córdoba (14 August 2021), and Seville. The mountains of Granada and Jaén have the coldest temperatures in southern Iberia, but do not reach continental extremes (and, indeed are surpassed by some mountains in northern Spain). In the cold snap of January 2005, Santiago de la Espada (Jaén) experienced a temperature of and the ski resort at Sierra Nevada National Park—the southernmost ski resort in Europe—dropped to . Sierra Nevada Natural Park has Iberia's lowest average annual temperature, ( at Pradollano) and its peaks remain snowy practically year-round. Terrain Mountain ranges affect climate, the network of rivers, soils and their erosion, bioregions, and even human economies insofar as they rely on natural resources. The Andalusian terrain offers a range of altitudes and slopes. Andalusia has the Iberian peninsula's highest mountains and nearly 15 percent of its terrain over . The picture is similar for areas under (with the Baetic Depression), and for the variety of slopes. The Atlantic coast is overwhelmingly beach and gradually sloping coasts; the Mediterranean coast has many cliffs, above all in the Malagan Axarquía and in Granada and Almería. This asymmetry divides the region naturally into (two mountainous areas) and (the broad basin of the Guadalquivir). The Sierra Morena separates Andalusia from the plains of Extremadura and Castile–La Mancha on Spain's Meseta Central. Although sparsely populated, this is not a particularly high range, and its highest point, the peak of La Bañuela in the Sierra Madrona, lies outside of Andalusia. Within the Sierra Morena, the gorge of Despeñaperros forms a natural frontier between Castile and Andalusia. The Baetic Cordillera consists of the parallel mountain ranges of the Cordillera Penibética near the Mediterranean coast and the Cordillera Subbética inland, separated by the Surco Intrabético. The Cordillera Subbética is quite discontinuous, offering many passes that facilitate transportation, but the Penibético forms a strong barrier between the Mediterranean coast and the interior. The Sierra Nevada, part of the Cordillera Penibética in the Province of Granada, has the highest peaks in Iberia: El Mulhacén at and El Veleta at . Lower Andalusia, the Baetic Depression, the basin of the Guadalquivir, lies between these two mountainous areas. It is a nearly flat territory, open to the Gulf of Cádiz in the southeast. Throughout history, this has been the most populous part of Andalusia. Hydrography Andalusia has rivers that flow into both the Atlantic and the Mediterranean. Flowing to the Atlantic are the Guadiana, Odiel-Tinto, Guadalquivir, Guadalete, and Barbate. Flowing to the Mediterranean are the Guadiaro, Guadalhorce, Guadalmedina, Guadalfeo, Andarax (also known as the Almería) and Almanzora. Of these, the Guadalquivir is the longest in Andalusia and fifth longest on the Iberian peninsula, at . The rivers of the Atlantic basin are characteristically long, run through mostly flat terrain, and have broad river valleys. As a result, at their mouths are estuaries and wetlands, such as the marshes of Doñana in the delta of the Guadalquivir, and wetlands of the Odiel. In contrast, the rivers of the Mediterranean Basin are shorter, more seasonal, and make a precipitous descent from the mountains of the Baetic Cordillera. Their estuaries are small, and their valleys are less suitable for agriculture. Also, being in the rain shadow of the Baetic Cordillera means that they receive a lesser volume of water. The following hydrographic basins can be distinguished in Andalusia. On the Atlantic side are the Guadalquivir basin; the Andalusian Atlantic Basin with the sub-basins Guadalete-Barbate and Tinto-Odiel; and the Guadiana basin. On the Mediterranean side is the Andalusian Mediterranean Basin and the upper portion of the basin of the Segura. Soils The soils of Andalusia can be divided into three large areas: the Sierra Morena, Cordillera Subbética, and the Baetic Depression and the Surco Intrabético. The Sierra Morena, due to its morphology and the acidic content of its rocks, developed principally relatively poor, shallow soils, suitable only for forests. In the valleys and in some areas where limestone is present, deeper soils allowed farming of cereals suitable for livestock. The more complicated morphology of the Baetic Cordillera makes it more heterogeneous, with the most heterogeneous soils in Andalusia. Very roughly, in contrast to the Sierra Morena, a predominance of basic (alkaline) materials in the Cordillera Subbética, combined with a hilly landscape, generates deeper soils with greater agricultural capacity, suitable to the cultivation of olives. Finally, the Baetic Depression and the Surco Intrabético have deep, rich soils, with great agricultural capacity. In particular, the alluvial soils of the Guadalquivir valley and plain of Granada have a loamy texture and are particularly suitable for intensive irrigated crops. In the hilly areas of the countryside, there is a double dynamic: the depressions have filled with older lime-rich material, developing the deep, rich, dark clay soils the Spanish call bujeo, or tierras negras andaluzas, excellent for dryland farming. In other zones, the whiter albariza provides an excellent soil for vineyards. Despite their marginal quality, the poorly consolidated soils of the sandy coastline of Huelva and Almería have been successfully used in recent decades for hothouse cultivation under clear plastic of strawberries, raspberries, blueberries, and other fruits. Flora Biogeographically, Andalusia forms part of the Western Mediterranean subregion of the Mediterranean Basin, which falls within the Boreal Kingdom. Five floristic provinces lie, in whole or in part, within Andalusia: along much of the Atlantic coast, the Lusitanian-Andalusian littoral or Andalusian Atlantic littoral; in the north, the southern portion of the Luso-Extremaduran floristic province; covering roughly half of the region, the Baetic floristic province; and in the extreme east, the Almerian portion of the Almerian-Murcian floristic province and (coinciding roughly with the upper Segura basin) a small portion of the Castilian-Maestrazgan-Manchegan floristic province. These names derive primarily from past or present political geography: "Luso" and "Lusitanian" from Lusitania, one of three Roman provinces in Iberia, most of the others from present-day Spanish provinces, and Maestrazgo being a historical region of northern Valencia. In broad terms, the typical vegetation of Andalusia is Mediterranean woodland, characterized by leafy xerophilic perennials, adapted to the long, dry summers. The dominant species of the climax community is the holly oak (Quercus ilex). Also abundant are cork oak (Quercus suber), various pines, and Spanish fir (Abies pinsapo). Due to cultivation, olive (Olea europaea) and almond (Prunus dulcis) trees also abound. The dominant understory is composed of thorny and aromatic woody species, such as rosemary (Rosmarinus officinalis), thyme (Thymus), and Cistus. In the wettest areas with acidic soils, the most abundant species are the oak and cork oak, and the cultivated Eucalyptus. In the woodlands, leafy hardwoods of genus Populus (poplars, aspens, cottonwoods) and Ulmus (elms) are also abundant; poplars are cultivated in the plains of Granada. The Andalusian woodlands have been much altered by human settlement, the use of nearly all of the best land for farming, and frequent wildfires. The degraded forests become shrubby and combustible garrigue. Extensive areas have been planted with non-climax trees such as pines. There is now a clear conservation policy for the remaining forests, which survive almost exclusively in the mountains. Fauna The biodiversity of Andalusia extends to its fauna as well. More than 400 of the 630 vertebrate species extant in Spain can be found in Andalusia. Spanning the Mediterranean and Atlantic basins, and adjacent to the Strait of Gibraltar, Andalusia is on the migratory route of many of the numerous flocks of birds that travel annually from Europe to Africa and back. The Andalusian wetlands host a rich variety of birds. Some are of African origin, such as the red-knobbed coot (Fulica cristata), the purple swamphen (Porphyrio porphyrio), and the greater flamingo (Phoenicopterus roseus). Others originate in Northern Europe, such as the greylag goose (Anser anser). Birds of prey (raptors) include the Spanish imperial eagle (Aquila adalberti), the griffon vulture (Gyps fulvus), and both the black and red kite (Milvus migrans and Milvus milvus). Among the herbivores, are several deer (Cervidae) species, notably the fallow deer (Dama dama) and roe deer (Capreolus capreolus); the European mouflon (Ovis aries musimon), a feral sheep; and the Spanish ibex (Capra pyrenaica, which despite its scientific name is no longer found in the Pyrenees). The Spanish ibex has recently been losing ground to the Barbary sheep (Ammotragus lervia), an invasive species from Africa, introduced for hunting in the 1970s. Among the small herbivores are rabbits—especially the European rabbit (Oryctolagus cuniculus)—which form the most important part of the diet of the carnivorous species of the Mediterranean woodlands. The large carnivores such as the Iberian wolf (Canis lupus signatus) and the Iberian lynx (Lynx pardinus) are quite threatened, and are limited to the Sierra de Andújar, inside of Sierra Morena, Doñana and Despeñaperros. Stocks of the wild boar (Sus scrofa), on the other hand, have been well preserved because they are popular with hunters. More abundant and in varied situations of conservation are such smaller carnivores as otters, dogs, foxes, the European badger (Meles meles), the European polecat (Mustela putorius), the least weasel (Mustela nivalis), the European wildcat (Felis silvestris), the common genet (Genetta genetta), and the Egyptian mongoose (Herpestes ichneumon). Other notable species are Acherontia atropos (a variety of death's-head hawkmoth), Vipera latasti (a venomous snake), and the endemic (and endangered) fish Aphanius baeticus. Protected areas Andalusia has many unique ecosystems. In order to preserve these areas in a manner compatible with both conservation and economic exploitation, many of the most representative ecosystems have been given protected status. The various levels of protection are encompassed within the Network of Protected Natural Spaces of Andalusia (Red de Espacios Naturales Protegidos de Andalucía, RENPA) which integrates all protected natural spaces located in Andalusia, whether they are protected at the level of the local community, the autonomous community of Andalusia, the Spanish state, or by international conventions. RENPA consists of 150 protected spaces, consisting of two national parks, 24 natural parks, 21 periurban parks (on the fringes of cities or towns), 32 natural sites, two protected countrysides, 37 natural monuments, 28 nature reserves, and four concerted nature reserves (in which a government agency coordinates with the owner of the property for its management), all part of the European Union's Natura 2000 network. Under the international ambit are the nine Biosphere Reserves, 20 Ramsar wetland sites, four Specially Protected Areas of Mediterranean Importance and two UNESCO Geoparks. In total, nearly 20 percent of the territory of Andalusia lies in one of these protected areas, which constitute roughly 30 percent of the protected territory of Spain. Among these many spaces, some of the most notable are the Sierras de Cazorla, Segura y Las Villas Natural Park, Spain's largest natural park and the second largest in Europe, the Sierra Nevada National Park, Doñana National Park and Natural Park, the Tabernas Desert, and the Cabo de Gata-Níjar Natural Park, the largest terrestrial-maritime reserve in the European Western Mediterranean Sea. History The geostrategic position of Andalusia in the extreme south of Europe, providing (along with Morocco) a gateway between Europe and Africa, added to its position between the Atlantic Ocean and the Mediterranean Sea, as well as its rich deposits of minerals and its agricultural wealth, have made Andalusia a tempting prize for civilizations since prehistoric times. Add to this its area of (larger than many European countries), and it can be no surprise that Andalusia has figured prominently in the history of Europe and the Mediterranean. Several theories postulate that the first hominids in Europe were in Andalusia, having passed across the Strait of Gibraltar; the earliest known paintings of humanity have been found in the Caves of Nerja, Málaga. The first settlers, based on artifacts from the archaeological sites at Los Millares, El Argar, and Tartessos, were clearly influenced by cultures of the Eastern Mediterranean who arrived on the Andalusian coast. Andalusia then went through a period of protohistory, when the region did not have a written language of its own, but its existence was known to and documented by literate cultures, principally the Phoenicians and Ancient Greeks, wide historical moment in which Cádiz was founded, regarded by many as the oldest city still standing in Western Europe; another city among the oldest is Málaga. During the second millennium BCE, the kingdom of Tartessos developed in Andalusia. Carthaginians and Romans With the fall of the original Phoenician cities in the East, Carthage – itself the most significant Phoenician colony – became the dominant sea power of the western Mediterranean and the most important trading partner for the Phoenician towns along the Andalusian coast. Between the First and Second Punic Wars, Carthage extended its control beyond Andalucia to include all of Iberia except the Basque Country. Some of the more prominent Andalusian cities during Carthaginian rule include Gadir (Cadiz), Qart Juba (Córdoba), Ilipa (near modern Seville), Malaka (Málaga) and Sexi or Seksi (near modern Almuñécar). Andalusia was the major staging ground for the war with Rome led by the Carthaginian general Hannibal. The Romans defeated the Carthaginians and conquered Andalusia, the region being renamed Baetica. It was fully incorporated into the Roman Empire, and from this region came many Roman magistrates and senators, as well as the emperors Trajan and (most likely) Hadrian. Vandals, Visigoths and the Byzantine Empire The Vandals moved briefly through the region during the 5th century AD before settling in North Africa, after which the region fell into the hands of the Visigothic Kingdom. The Visigoths in this region were practically independent of the Visigothic Catholic Kingdom of Toledo. This is the era of Saints Isidore of Seville and Hermenegild. During this period, around 555 AD, the Eastern Roman Empire conquered Andalusia under Justinian I, the Eastern Roman emperor. They established Spania, a province of the Byzantine Empire from 552 until 624. Although their holdings were quickly reduced, they continued to have interests in the region until it was lost altogether in 624. Al-Andalus states The Visigothic era came to an abrupt end in 711 with the Umayyad conquest of Hispania by the Muslim Umayyad general Tariq ibn Ziyad. Tariq is known in Umayyad history and legend as a formidable conqueror who burned his fleet of ships when he landed with his troops on the coast of Gibraltar – an acronym of "Jabel alTariq" meaning "the mountain of Tariq". When the Muslim invaders seized control and consolidated their dominion of the region, they remained tolerant of the local faiths, but they also needed a place for their own faith. In the 750s, they forcibly rented half of Córdoba 's Cathedral of San Vicente (Visigothic) to use as a mosque. The mosque's hypostyle plan, consisting of a rectangular prayer hall and an enclosed courtyard, followed a tradition established in the Umayyad and Abbasid mosques of Syria and Iraq while the dramatic articulation of the interior of the prayer hall was unprecedented. The system of columns supporting double arcades of piers and arches with alternating red and white voussoirs is an unusual treatment that, structurally, combined striking visual effect with the practical advantage of providing greater height within the hall. Alternating red and white voussoirs are associated with Umayyad monuments such as the Great Mosque of Damascus and the Dome of the Rock. Their use in the Great Mosque of Córdoba manages to create a stunningly original visual composition even as it emphasises 'Abd al-Rahman's connection to the established Umayyad tradition. In this period, the name "Al-Andalus" was applied to the Iberian Peninsula, and later it referred to the parts not controlled by the Gothic states in the North. The Muslim rulers in Al-Andalus were economic invaders and interested in collecting taxes; social changes imposed on the native populace were mainly confined to geographical, political and legal conveniences. Al-Andalus remained connected to other states under Muslim rule; also trade routes between it and Constantinople and Alexandria remained open, while many cultural features of the Roman Empire were transmitted throughout Europe and the Near East by its successor state, the Byzantine Empire. Byzantine architecture is an example of such cultural diffusion continuing even after the collapse of the empire. Nevertheless, the Guadalquivir River valley became the point of power projection in the peninsula with the Caliphate of Córdoba making Córdoba its capital. The Umayyad Caliphate produced such leaders as Caliph Abd-ar-Rahman III (ruled 912–961) and his son, Caliph Al-Hakam II (ruled 961–976) and built the magnificent Great Mosque of Córdoba. Under these rulers, Córdoba was the center of economic and cultural significance. By the 10th century, the northern Kingdoms of Spain and other European Crowns had begun what would eventually become the Reconquista: the reconquest of the Iberian Peninsula for Christendom. Caliph Abd-ar-Rahman suffered some minor military defeats, but often managed to manipulate the Gothic northern kingdoms to act against each other's interests. Al-Hakam achieved military successes, but at the expense of uniting the north against him. In the 10th century the Saracen rulers of Andalusia had a Slavic army of 13,750 men. After the conquest of Toledo in 1086 by Alfonso VI, the Crown of Castille and the Crown of Aragon dominated large parts of the peninsula. The main Taifas therefore had to resort to assistance from various other powers across the Mediterranean. A number of different Muslim dynasties of North African origin—notably Almoravid dynasty and Almohad dynasty—dominated a slowly diminishing Al-Andalus over the next several centuries. After the victory at the Battle of Sagrajas (1086) put a temporary stop to Castilian expansion, the Almoravid dynasty reunified Al-Andalus with its capital in Córdoba, ruling until the mid-12th century. The various Taifa kingdoms were assimilated. the Almohad dynasty expansion in North Africa weakened Al-Andalus, and in 1170 the Almohads transferred their capital from Marrakesh to Seville. The victory at the Battle of Las Navas de Tolosa (1212) marked the beginning of the end of the Almohad dynasty. Crown of Castile The weakness caused by the collapse of Almohad power and the subsequent creation of new Taifas, each with its own ruler, led to the rapid Castile reconquest of the valley of the Guadalquivir. Córdoba was regained in 1236 and Seville in 1248. The fall of Granada on 2 January 1492 put an end to the Nasrid rule; an event that marks the beginning of Andalusia, the southern four territories of the Crown of Castile in the Iberian Peninsula. Seven months later, on 3 August 1492 Christopher Columbus left the town of Palos de la Frontera, Huelva, with the first expedition that resulted in the Discovery of the Americas, that would end the Middle Ages and signal the beginning of modernity. Many Castilians participated in this and other expeditions that followed, some of them known as the Minor or Andalusian Journeys. Contacts between Spain and the Americas, including royal administration and the shipping trade from Asia and America for over three hundred years, came almost exclusively through the south of Spain, specially Seville and Cadiz ports. As a result, it became the wealthiest, most influential region in Spain and amongst the most influential in Europe. For example, the Habsburg diverted much of this trade wealth to control its European territories. Habsburg Spain In the first half of the 16th century plague was still prevalent in Spain. According to George C. Kohn, "One of the worst epidemics of the century, whose miseries were accompanied by severe drought and food shortage, started in 1505; by 1507, about 100,000 people had died in Andalusia alone. Andalusia was struck once again in 1646. For three years, plague haunted the entire region, causing perhaps as many as 200,000 deaths, especially in Málaga and Seville." A second insurrection, the Morisco Revolt (1568–1571), ensued in the Kingdom of Granada. It was crushed and the demographics of the kingdom of Granada was hammered, with the Morisco population decreasing in number by more than 100,000 including deaths, flights and deportations, contrasting with the less than 40,000 number of incoming settlers. In 1810–12 Spanish troops strongly resisted the French occupation during the Peninsular War (part of the Napoleonic Wars). Andalusia profited from the Spanish overseas empire, although much trade and finance eventually came to be controlled by other parts of Europe to where it was ultimately destined. In the 18th century, commerce from other parts of Spain began to displace Andalusian commerce when the Spanish government ended Andalusia's trading monopoly with the colonies in the Americas. The loss of the empire in the 1820s hurt the economy of the region, particularly the cities that had benefited from the trade and ship building. The construction of railways in the latter part of the 19th century enabled Andalusia to better develop its agricultural potential and it became an exporter of food. While industrialisation was taking off in the northern Spanish regions of Catalonia and the Basque country, Andalusia remained traditional and displayed a deep social division between a small class of wealthy landowners and a population made up largely of poor agricultural labourers and tradesmen. Francoist oppressions Andalusia was one of the worst affected regions of Spain by Francisco Franco's brutal campaign of mass-murder and political suppression called the White Terror during and after the Spanish Civil War. The Nationalist rebels bombed and seized the working-class districts of the main Andalusian cities in the first days of the war, and afterwards went on to execute thousands of workers and militants of the leftist parties: in the city of Córdoba 4,000; in the city of Granada 5,000; in the city of Seville 3,028; and in the city of Huelva 2,000 killed and 2,500 disappeared. The city of Málaga, occupied by the Nationalists in February 1937 following the Battle of Málaga, experienced one of the harshest repressions following Francoist victory with an estimated total of 17,000 people summarily executed. Carlos Arias Navarro, then a young lawyer who as public prosecutor signed thousands of execution warrants in the trials set up by the triumphant rightists, became known as "The Butcher of Málaga" (Carnicero de Málaga). Paul Preston estimates the total number of victims of deliberately killed by the Nationalists in Andalusia at 55,000. Government and politics Andalusia is one of the 17 autonomous communities of Spain. The Regional Government of Andalusia (Spanish: Junta de Andalucía) includes the Parliament of Andalusia, its chosen president, a Consultative Council, and other bodies. The Autonomous Community of Andalusia was formed in accord with a referendum of 28 February 1980 and became an autonomous community under the 1981 Statute of Autonomy known as the Estatuto de Carmona. The process followed the Spanish Constitution of 1978, still current as of 2009, which recognizes and guarantees the right of autonomy for the various regions and nationalities of Spain. The process to establish Andalusia as an autonomous region followed Article 151 of the Constitution, making Andalusia the only autonomous community to take that particular course. That article was set out for regions like Andalusia that had been prevented by the outbreak of the Spanish Civil War from adopting a statute of autonomy during the period of the Second Spanish Republic. Article 1 of the 1981 Statute of Autonomy justifies autonomy based on the region's "historical identity, on the self-government that the Constitution permits every nationality, on outright equality to the rest of the nationalities and regions that compose Spain, and with a power that emanates from the Andalusian Constitution and people, reflected in its Statute of Autonomy". In October 2006 the constitutional commission of the Cortes Generales (the national legislature of Spain), with favorable votes from the left-of-center Spanish Socialist Workers' Party (PSOE), the leftist United Left (IU) and the right-of-center People's Party (PP), approved a new Statute of Autonomy for Andalusia, whose preamble refers to the community as a "national reality" (realidad nacional): On 2 November 2006 the Spanish Chamber Deputies ratified the text of the Constitutional Commission with 306 votes in favor, none opposed, and 2 abstentions. This was the first time a Spanish Organic Law adopting a Statute of Autonomy was approved with no opposing votes. The Senate, in a plenary session of 20 December 2006, ratified the referendum to be voted upon by the Andalusian public 18 February 2007. The Statute of Autonomy spells out Andalusia's distinct institutions of government and administration. Chief among these is the Andalusian Autonomous Government (Junta de Andalucía). Other institutions specified in the Statute are the Defensor del Pueblo Andaluz (literally "Defender of the Andalusian People", basically an ombudsperson), the Consultative Council, the Chamber of Accounts, the Audiovisual Council of Andalusia, and the Economic and Social Council. The Andalusian Statute of Autonomy recognizes Seville as the autonomy's capital. The Andalusian Autonomous Government is located there. The region's highest court, the High Court of Andalusia (Tribunal Superior de Justicia de Andalucía) is not part of the Autonomous Government, and has its seat in Granada. Autonomous Government The Andalusian Autonomous Government (Junta de Andalucía) is the institution of self-government of the Autonomous Community of Andalusia. Within the government, the President of Andalusia is the supreme representative of the autonomous community, and the ordinary representative of the Spanish state in the autonomous community. The president is formally named to the position by the Monarch of Spain and then confirmed by a majority vote of the Parliament of Andalusia. In practice, the monarch always names a person acceptable to the ruling party or coalition of parties in the autonomous region. In theory, were the candidate to fail to gain the needed majority, the monarch could propose a succession of candidates. After two months, if no proposed candidate could gain the parliament's approval, the parliament would automatically be dissolved and the acting president would call new elections. On 18 January 2019 Juan Manuel Moreno was elected as the sixth president of Andalusia. The Council of Government, the highest political and administrative organ of the Community, exercises regulatory and executive power. The President presides over the council, which also includes the heads of various departments (Consejerías). In the current legislature (2008–2012), there are 15 of these departments. In order of precedence, they are Presidency, Governance, Economy and Treasury, Education, Justice and Public Administration, Innovation, Science and Business, Public Works and Transportation, Employment, Health, Agriculture and Fishing, Housing and Territorial Planning, Tourism, Commerce and Sports, Equality and Social Welfare, Culture, and Environment. The Parliament of Andalusia, its Autonomic Legislative Assembly, develops and approves laws and elects and removes the President. Elections to the Andalusian Parliament follow a democratic formula through which the citizens elect 109 representatives. After the approval of the Statute of Autonomy through Organic Law 6/1981 on 20 December 1981, the first elections to the autonomic parliament took place 23 May 1982. Further elections have occurred in 1986, 1990, 1994, 1996, 2000, 2004, and 2008. The current (2008–2012) legislature includes representatives of the PSOE-A (Andalusian branch of the left-of-center PSOE), PP-A (Andalusian branch of the right-of-center PP) and IULV-CA (Andalusian branch of the leftist IU). Judicial power The High Court of Andalusia (Tribunal Superior de Justicia de Andalucía) in Granada is subject only to the higher jurisdiction of the Supreme Court of Spain. The High Court is not an organ of the Autonomous Community, but rather of the Judiciary of Spain, which is unitary throughout the kingdom and whose powers are not transferred to the autonomous communities. The Andalusian territory is divided into 88 legal/judicial districts (partidos judiciales). Administrative divisions Provinces Andalusia consists of eight provinces. The latter were established by Javier de Burgos in the 1833 territorial division of Spain. Each of the Andalusian provinces bears the same name as its capital: Andalusia is traditionally divided into two historical subregions: or (Andalucía Oriental), consisting of the provinces of Almería, Granada, Jaén, and Málaga, and or (Andalucía Occidental), consisting of the provinces of Cádiz, Córdoba, Huelva and Seville. Comarcas and mancomunidades Within the various autonomous communities of Spain, comarcas are comparable to shires (or, in some countries, counties) in the English-speaking world. Unlike in some of Spain's other autonomous communities, under the original 1981 Statute of Autonomy, the comarcas of Andalusia had no formal recognition, but, in practice, they still had informal recognition as geographic, cultural, historical, or in some cases administrative entities. The 2007 Statute of Autonomy echoes this practice, and mentions comarcas in Article 97 of Title III, which defines the significance of comarcas and establishes a basis for formal recognition in future legislation. The current statutory entity that most closely resembles a comarca is the , a freely chosen, bottom-up association of municipalities intended as an instrument of socioeconomic development and coordination between municipal governments in specific areas. Municipalities and local entities Beyond the level of provinces, Andalusia is further divided into 774 municipalities (municipios). The municipalities of Andalusia are regulated by Title III of the Statute of Autonomy, Articles 91–95, which establishes the municipality as the basic territorial entity of Andalusia, each of which has legal personhood and autonomy in many aspects of its internal affairs. At the municipal level, representation, government and administration is performed by the ayuntamiento (municipal government), which has competency for urban planning, community social services, supply and treatment of water, collection and treatment of waste, and promotion of tourism, culture, and sports, among other matters established by law. Among the more important Andalusian cities besides the provincial capitals are: El Ejido, Níjar and Roquetas de Mar (Almería) La Línea de la Concepción, Algeciras, Sanlúcar de Barrameda, San Fernando, Chiclana de la Frontera, Puerto Real, Arcos de la Frontera, Jerez and El Puerto de Santa María (Cádiz) Lucena, Pozoblanco, Montilla and Puente Genil (Córdoba) Almuñécar, Guadix, Loja and Motril (Granada) Linares, Andújar, Úbeda and Baeza (Jaén) Marbella, Mijas, Vélez-Málaga, Fuengirola, Torremolinos, Estepona, Benalmádena, Antequera, Rincón de la Victoria and Ronda (Málaga) Utrera, Dos Hermanas, Alcalá de Guadaíra, Osuna, Mairena del Aljarafe, Écija and Lebrija (Sevilla) In conformity with the intent to devolve control as locally as possible, in many cases, separate nuclei of population within municipal borders each administer their own interests. These are variously known as pedanías ("hamlets"), villas ("villages"), aldeas (also usually rendered as "villages"), or other similar names. Main cities Demographics Andalusia ranks first by population among the 17 autonomous communities of Spain. The estimated population at the beginning of 2009 was 8,285,692. The population is concentrated, above all, in the provincial capitals and along the coasts, so that the level of urbanization is quite high; half the population is concentrated in the 28 cities of more than 50,000 inhabitants. The population is aging, although the process of immigration is countering the inversion of the population pyramid. Population change At the end of the 20th century, Andalusia was in the last phase of demographic transition. The death rate stagnated at around 8–9 per thousand, and the population came to be influenced mainly by birth and migration. In 1950, Andalusia had 20.04 percent of the national population of Spain. By 1981, this had declined to 17.09 percent. Although the Andalusian population was not declining in absolute terms, these relative losses were due to emigration great enough to nearly counterbalance having the highest birth rate in Spain. Since the 1980s, this process has reversed on all counts, and as of 2009, Andalusia has 17.82 percent of the Spanish population. The birth rate is sharply down, as is typical in developed economies, although it has lagged behind much of the rest of the world in this respect. Furthermore, prior emigrants have been returning to Andalusia. Beginning in the 1990s, others have been immigrating in large numbers as well, as Spain has become a country of net immigration. At the beginning of the 21st century, statistics show a slight increase in the birth rate, due in large part to the higher birth rate among immigrants. The result is that as of 2009, the trend toward rejuvenation of the population is among the strongest of any autonomous community of Spain, or of any comparable region in Europe. Structure At the beginning of the 21st century, the population structure of Andalusia shows a clear inversion of the population pyramid, with the largest cohorts falling between ages 25 and 50. Comparison of the population pyramid in 2008 to that in 1986 shows: A clear decrease in the population under the age of 25, due to a declining birth rate. An increase in the adult population, as the earlier, larger cohort born in the "baby boom" of the 1960s and 1970s reach adulthood. This effect has been exacerbated by immigration: the largest contingent of immigrants are young adults. A further increase in the adult population, and especially the older adult population, due to increased life expectancy. As far as composition by sex, two aspects stand out: the higher percentage of women in the elderly population, owing to women's longer life expectancy, and, on the other hand, the higher percentage of men of working age, due in large part to a predominantly male immigrant population. Immigration In 2005, 5.35 percent of the population of Andalusia were born outside of Spain. This is a relatively low number for a Spanish region, the national average being three percentage points higher. The immigrants are not evenly distributed among the Andalusian provinces: Almería, with a 15.20 percent immigrant population, is third among all provinces in Spain, while at the other extreme Jaén is only 2.07 percent immigrants and Córdoba 1.77 percent. The predominant nationalities among the immigrant populations are Moroccan (92,500, constituting 17.79 percent of the foreigners living in Andalusia) and British (15.25 percent across the region). When comparing world regions rather than individual countries, the single largest immigrant block is from the region of Latin America, outnumbering not only all North Africans, but also all non-Spanish Western Europeans. Demographically, this group has provided an important addition to the Andalusian labor force. Economy Andalusia is traditionally an agricultural area, but the service sector (particularly tourism, retail sales, and transportation) now predominates. The once booming construction sector, hit hard by the 2009 recession, was also important to the region's economy. The industrial sector is less developed than most other regions in Spain. Between 2000 and 2006 economic growth per annum was 3.72%, one of the highest in the country. Still, according to the Spanish (INE), the GDP per capita of Andalusia (€17,401; 2006) remains the second lowest in Spain, with only Extremadura lagging behind. The Gross domestic product (GDP) of the autonomous community was 160.6 billion euros in 2018, accounting for 13.4% of Spanish economic output. GDP per capita adjusted for purchasing power was 20,500 euros or 68% of the EU27 average in the same year. Primary sector The primary sector, despite adding the least of the three sectors to the regional GDP remains important, especially when compared to typical developed economies. The primary sector produces 8.26 percent of regional GDP, 6.4 percent of its GVA and employs 8.19 percent of the workforce. In monetary terms it could be considered a rather uncompetitive sector, given its level of productivity compared to other Spanish regions. In addition to its numeric importance relative to other regions, agriculture and other primary sector activities have strong roots in local culture and identity. The primary sector is divided into a number of subsectors: agriculture, commercial fishing, animal husbandry, hunting, forestry, mining, and energy. Agriculture, husbandry, hunting, and forestry For many centuries, agriculture dominated Andalusian society, and, with 44.3 percent of its territory cultivated and 8.4 percent of its workforce in agriculture as of 2016 it remains an integral part of Andalusia's economy. However, its importance is declining, like the primary and secondary sectors generally, as the service sector is increasingly taking over. The primary cultivation is dryland farming of cereals and sunflowers without artificial irrigation, especially in the vast countryside of the Guadalquivir valley and the high plains of Granada and Almería-with a considerably lesser and more geographically focused cultivation of barley and oats. Using irrigation, maize, cotton and rice are also grown on the banks of the Guadalquivir and Genil. The most important tree crops are olives, especially in the Subbetic regions of the provinces of Córdoba and Jáen, where irrigated olive orchards constitute a large component of agricultural output. There are extensive vineyards in various zones such as Jerez de la Frontera (sherry), Condado de Huelva, Montilla-Moriles and Málaga. Fruits—mainly citrus fruits—are grown near the banks of the Guadalquivir; almonds, which require far less water, are grown on the high plains of Granada and Almería. In monetary terms, by far the most productive and competitive agriculture in Andalusia is the intensive forced cultivation of strawberries, raspberries, blueberries, and other fruits grown under hothouse conditions under clear plastic, often in sandy zones, on the coasts, in Almería and Huelva. Organic farming has recently undergone rapid expansion in Andalusia, mainly for export to European markets but with increasing demand developing in Spain. Andalusia has a long tradition of animal husbandry and livestock farming, but it is now restricted mainly to mountain meadows, where there is less pressure from other potential uses. Andalusians have a long and colourful history of dog breeding that can be observed throughout the region today. The raising of livestock now plays a semi-marginal role in the Andalusian economy, constituting only 15 percent of the primary sector, half the number for Spain taken as a whole. "Extensive" raising of livestock grazes the animals on natural or cultivated pastures, whereas "intensive" raising of livestock is based in fodder rather than pasture. Although the productivity is higher than with extensive techniques, the economics are quite different. While intensive techniques now dominate in Europe and even in other regions of Spain, most of Andalusia's cattle, virtually all of its sheep and goats, and a good portion of its pigs are raised by extensive farming in mountain pastures. This includes the Black Iberian pigs that are the source of Jamón ibérico. Andalusia's native sheep and goats present a great economic opportunity in a Europe where animal products are generally in strong supply, but the sheep and goat meat, milk, and leather (and the products derived from these) are relatively scarce. Dogs are bred not just as companion animals, but also as herding animals used by goat and sheep herders. Hunting remains relatively important in Andalusia, but has largely lost its character as a means of obtaining food. It is now more of a leisure activity linked to the mountain areas and complementary to forestry and the raising of livestock. Dogs are frequently used as hunting companions to retrieve killed game. The Andalusian forests are important for their extent—50 percent of the territory of Andalusia—and for other less quantifiable environmental reasons, such as their value in preventing erosion, regulating the flow of water necessary for other flora and fauna. For these reasons, there is legislation in place to protect the Andalusian forests. The value of forest products as such constitutes only 2 percent of agricultural production. This comes mostly from cultivated species—eucalyptus in Huelva and poplar in Granada—as well as naturally occurring cork oak in the Sierra Morena. Fishing Fishing is a longstanding tradition on the Andalusian coasts. Fish and other seafood have long figured prominently in the local diet and in the local gastronomic culture: fried fish (pescaito frito in local dialect), white prawns, almadraba tuna, among others. The Andalusian fishing fleet is Spain's second largest, after Galicia, and Andalusia's 38 fishing ports are the most of any Spanish autonomous community. Commercial fishing produces only 0.5 percent of the product of the regional primary sector by value, but there are areas where it has far greater importance. In the province of Huelva it constitutes 20 percent of the primary sector, and locally in Punta Umbría 70 percent of the work force is involved in commercial fishing. Failure to comply with fisheries laws regarding the use of trawling, urban pollution of the seacoast, destruction of habitats by coastal construction (for example, alteration of the mouths of rivers, construction of ports), and diminution of fisheries by overexploitation have created a permanent crisis in the Andalusian fisheries, justifying attempts to convert the fishing fleet. The decrease in fish stocks has led to the rise of aquaculture, including fish farming both on the coasts and in the interior. Mining Despite the general poor returns in recent years, mining retains a certain importance in Andalusia. Andalusia produces half of Spain's mining product by value. Of Andalusia's production, roughly half comes from the province of Huelva. Mining for precious metals at Minas de Riotinto in Huelva (see Rio Tinto Group) dates back to pre-Roman times; the mines were abandoned in the Middle Ages and rediscovered in 1556. Other mining activity is coal mining in the Guadiato valley in the province of Córdoba; various metals at Aznalcóllar in the province of Seville, and iron at Alquife in the province of Granada. In addition, limestone, clay, and other materials used in construction are well distributed throughout Andalusia. Secondary sector: industry The Andalusian industrial sector has always been relatively small. Nevertheless, in 2007, Andalusian industry earned 11.979 million euros and employed more than 290,000 workers. This represented 9.15 percent of regional GDP, far below the 15.08 the secondary sector represents in the economy of Spain as a whole. By analyzing the different subsectors of the food industry Andalusian industry accounts for more than 16% of total production. In a comparison with the Spanish economy, this subsector is virtually the only food that has some weight in the national economy with 16.16%. Lies far behind the manufacturing sector of shipping materials just over 10% of the Spanish economy. Companies like Cruzcampo (Heineken Group), Puleva, Domecq, Santana Motors or Renault-Andalusia, are exponents of these two subsectors. Of note is the Andalusian aeronautical sector, which is second nationally only behind Madrid and represents approximately 21% of total turnover in terms of employment, highlighting companies like Airbus, Airbus Military, or the newly formed Aerospace Alestis. On the contrary it is symptomatic of how little weight the regional economy in such important sectors such as textiles or electronics at the national level. Andalusian industry is also characterized by a specialization in industrial activities of transforming raw agricultural and mineral materials. This is largely done by small enterprises without the public or foreign investment more typical of a high level of industrialization. Tertiary sector: services In recent decades the Andalusian tertiary (service) sector has grown greatly, and has come to constitute the majority of the regional economy, as is typical of contemporary economies in developed nations. In 1975 the service sector produced 51.1 percent of local GDP and employed 40.8 percent of the work force. In 2007, this had risen to 67.9 percent of GDP and 66.42 percent of jobs. This process of "tertiarization" of the economy has followed a somewhat unusual course in Andalusia. This growth occurred somewhat earlier than in most developed economies and occurred independently of the local industrial sector. There were two principal reasons that "tertiarization" followed a different course in Andalusia than elsewhere: 1. Andalusian capital found it impossible to compete in the industrial sector against more developed regions, and was obligated to invest in sectors that were easier to enter. 2. The absence of an industrial sector that could absorb displaced agricultural workers and artisans led to the proliferation of services with rather low productivity. This unequal development compared to other regions led to a hypertrophied and unproductive service sector, which has tended to reinforce underdevelopment, because it has not led to large accumulations of capital. Tourism in Andalusia Due in part to the relatively mild winter and spring climate, the south of Spain is attractive to overseas visitors–especially tourists from Northern Europe. While inland areas such as Jaén, Córdoba and the hill villages and towns remain relatively untouched by tourism, the coastal areas of Andalusia have heavy visitor traffic for much of the year. Among the autonomous communities, Andalusia is second only to Catalonia in tourism, with nearly 30 million visitors every year. The principal tourist destinations in Andalusia are the Costa del Sol and (secondarily) the Sierra Nevada. As discussed above, Andalusia is one of the sunniest and warmest places in Europe, making it a center of "sun and sand" tourism, but not only it. Around 70 percent of the lodging capacity and 75 percent of the nights booked in Andalusian hotels are in coastal municipalities. The largest number of tourists come in August—13.26 percent of the nights booked throughout the year—and the smallest number in December—5.36 percent. On the west (Atlantic) coast are the Costa de la Luz (provinces of Huelva and Cádiz), and on the east (Mediterranean) coast, the Costa del Sol (provinces of Cádiz y Málaga), Costa Tropical (Granada and part of Almería) and the Costa de Almería. In 2004, the Blue Flag beach program of the non-profit Foundation for Environmental Education recognized 66 Andalusian beaches and 18 pleasure craft ports as being in a good state of conservation in terms of sustainability, accessibility, and quality. Nonetheless, the level of tourism on the Andalusian coasts has been high enough to have a significant environmental impact, and other organizations—such as the Spanish Ecologists in Action (Ecologistas en Acción) with their description of "Black Flag beaches" or Greenpeace—have expressed the opposite sentiment. Still, Hotel chains such as Fuerte Hotels have ensured that sustainability within the tourism industry is one of their highest priorities. Together with "sand and sun" tourism, there has also been a strong increase in nature tourism in the interior, as well as cultural tourism, sport tourism, and conventions. One example of sport and nature tourism is the ski resort at Sierra Nevada National Park. As for cultural tourism, there are hundreds of cultural tourist destinations: cathedrals, castles, forts, monasteries, and historic city centers and a wide variety of museums. It can be highlighted that Spain has seven of its 42 cultural UNESCO World Heritage Sites in Andalucia: Alhambra, Generalife and Albayzín, Granada (1984,1994) Antequera Dolmens Site (2016) 10th Century Caliphate City of Medina Azahara (2018) Cathedral, Alcázar and Archivo de Indias in Seville (1987) Historic centre of Córdoba (1984,1994) Renaissance Monumental Ensembles of Úbeda and Baeza (2003) Rock Art of the Mediterranean Basin on the Iberian Peninsula (1998) Further, there are the Lugares colombinos, significant places in the life of Christopher Columbus: Palos de la Frontera, La Rábida Monastery, and Moguer) in the province of Huelva. There are also archeological sites of great interest: the Roman city of Italica, birthplace of Emperor Trajan and (most likely) Hadrian or Baelo Claudia near Tarifa. Andalusia was the birthplace of such great painters as Velázquez and Murillo (Seville) and, more recently, Picasso (Málaga); Picasso is memorialized by his native city at the Museo Picasso Málaga and Natal House Foundation; the Casa de Murillo was a house museum 1982–1998, but is now mostly offices for the Andalusian Council of Culture. The CAC Málaga (Museum of Modern Art) is the most visited museum of Andalusia and has offered exhibitions of artists such as Louise Bourgeois, Jake and Dinos Chapman, Gerhard Richter, Anish Kapoor, Ron Mueck or Rodney Graham. Malaga is also located part of the private Carmen Thyssen-Bornemisza Collection at Carmen Thyssen Museum. There are numerous other significant museums around the region, both of paintings and of archeological artifacts such as gold jewelry, pottery and other ceramics, and other works that demonstrate the region's artisanal traditions. The Council of Government has designated the following "Municipios Turísticos": in Almería, Roquetas de Mar; in Cádiz, Chiclana de la Frontera, Chipiona, Conil de la Frontera, Grazalema, Rota, and Tarifa; in Granada, Almuñécar; in Huelva, Aracena; in Jaén, Cazorla; in Málaga, Benalmádena, Fuengirola, Nerja, Rincón de la Victoria, Ronda, and Torremolinos; in Seville, Santiponce.

Infrastructure Transport As in any modern society, transport systems are an essential structural element of the functioning of Andalusia. The transportation network facilitates territorial coordination, economic development and distribution, and intercity transportation. In urban transport, underdeveloped public transport systems put pedestrian traffic and other non-motorized traffic are at a disadvantage compared to the use of private vehicles. Several Andalusian capitals—Córdoba, Granada and Seville—have recently been trying to remedy this by strengthening their public transport systems and providing a better infrastructure for the use of bicycles. There are now three rapid transit systems operating in Andalucia – the Seville Metro, Málaga Metro and Granada Metro. Cercanías commuter rail networks operate in Seville, Málaga and Cádiz. For over a century, the conventional rail network has been centralized on the regional capital, Seville, and the national capital, Madrid; in general, there are no direct connections between provincial capitals. High-speed AVE trains run from Madrid via Córdoba to Seville and Málaga, from which a branch from Antequera to Granada opened in 2019. Further AVE routes are under construction. The Madrid-Córdoba-Seville route was the first high-velocity route in Spain (operating since 1992). Other principal routes are the one from Algeciras to Seville and from Almería via Granada to Madrid. Most of the principal roads have been converted into limited access highways known as autovías. The Autovía del Este (Autovía A-4) runs from Madrid through the Despeñaperros Natural Park, then via Bailén, Córdoba, and Seville to Cádiz, and is part of European route E05 in the International E-road network. The other main road in the region is the portion of European route E15, which runs as the Autovia del Mediterráneo along the Spanish Mediterranean coast. Parts of this constitute the superhighway Autopista AP-7, while in other areas it is Autovía A-7. Both of these roads run generally east–west, although the Autovía A-4 turns to the south in western Andalusia. Other first-order roads include the Autovía A-48 roughly along the Atlantic coast from Cádiz to Algeciras, continuing European route E05 to meet up with European route E15; the Autovía del Quinto Centenario (Autovía A-49), which continues west from Seville (where the Autovía A-4 turns toward the south) and goes on to Huelva and into Portugal as European route E01; the Autovía Ruta de la Plata (Autovía A-66), European route E803, which roughly corresponds to the ancient Roman 'Silver Route' from the mines of northern Spain, and runs north from Seville; the Autovía de Málaga (Autovía A-45), which runs south from Córdoba to Málaga; and the Autovía de Sierra Nevada (Autovía A-44), part of European route E902, which runs south from Jaén to the Mediterranean coast at Motril. As of 2008 Andalusia has six public airports, all of which can legally handle international flights. The Málaga Airport is dominant, handling 60.67 percent of passengers and 85 percent of its international traffic. The Seville Airport handles another 20.12 percent of traffic, and the Jerez Airport 7.17 percent, so that these three airports account for 87.96 percent of traffic. Málaga Airport is the international airport that offers a wide variety of international destinations. It has a daily link with twenty cities in Spain and over a hundred cities in Europe (mainly in Great Britain, Central Europe and the Nordic countries but also the main cities of Eastern Europe: Moscow, Saint Petersburg, Sofia, Riga or Bucharest), North Africa, Middle East (Riyadh, Jeddah and Kuwait) and North America (New York, Toronto and Montreal). The main ports are Algeciras (for freight and container traffic) and Málaga for cruise ships. Algeciras is Spain's leading commercial port, with of cargo in 2004. Seville has Spain's only commercial river port. Other significant commercial ports in Andalusia are the ports of the Bay of Cádiz, Almería and Huelva. The Council of Government has approved a Plan of Infrastructures for the Sustainability of Transport in Andalusia (PISTA) 2007–2013, which plans an investment of 30 billion euros during that period. Energy infrastructure The lack of high-quality fossil fuels in Andalusia has led to a strong dependency on petroleum imports. Still, Andalusia has a strong potential for the development of renewable energy, above all wind energy. The Andalusian Energy Agency established in 2005 by the autonomous government, is a new governmental organ charged with the development of energy policy and provision of a sufficient supply of energy for the community. The infrastructure for production of electricity consists of eight large thermal power stations, more than 70 hydroelectric power plants, two wind farms, and 14 major cogeneration facilities. Historically, the largest Andalusian business in this sector was the Compañía Sevillana de Electricidad, founded in 1894, absorbed into Endesa in 1996. The Solar power tower PS10 was built by the Andalusian firm Abengoa in Sanlúcar la Mayor in the province of Seville, and began operating in March 2007. It is the largest existing solar power facility in Europe. Smaller solar power stations, also recent, exist at Cúllar and Galera, Granada, inaugurated by Geosol and Caja Granada. Two more large thermosolar facilities, Andasol I y II, planned at Hoya de Guadix in the province of Granada are expected to supply electricity to half a million households. The Plataforma Solar de Almería (PSA) in the Tabernas Desert is an important center for the exploration of the solar energy. The largest wind power firm in the region is the Sociedad Eólica de Andalucía, formed by the merger of Planta Eólica del Sur S.A. and Energía Eólica del Estrecho S.A. The Medgaz gas pipeline directly connects the Algerian town of Béni Saf to Almería. Education As throughout Spain, basic education in Andalusia is free and compulsory. Students are required to complete ten years of schooling, and may not leave school before the age of 16, after which students may continue on to a baccalaureate, to intermediate vocational education, to intermediate-level schooling in arts and design, to intermediate sports studies, or to the working world. Andalusia has a tradition of higher education dating back to the Modern Age and the University of Granada, University of Baeza, and University of Osuna. there were ten private or public universities in Andalusia. University studies are structured in cycles, awarding degrees based on ECTS credits in accord with the Bologna process, which the Andalusian universities are adopting in accord with the other universities of the European Higher Education Area. Healthcare Responsibility for healthcare jurisdictions devolved from the Spanish government to Andalusia with the enactment of the Statute of Autonomy. Thus, the Andalusian Health Service (Servicio Andaluz de Salud) currently manages almost all public health resources of the Community, with such exceptions as health resources for prisoners and members of the military, which remain under central administration. Science and technology According to the Outreach Program for Science in Andalusia, Andalusia contributes 14 percent of Spain's scientific production behind only Madrid and Catalonia among the autonomous communities, even though regional investment in research and development (R&D) as a proportion of GDP is below the national average. The lack of research capacity in business and the low participation of the private sector in research has resulted in R&D taking place largely in the public sector. The Council of Innovation, Science and Business is the organ of the autonomous government responsible for universities, research, technological development, industry, and energy. The council coordinates and initiates scientific and technical innovation through specialized centers an initiatives such as the Andalusian Center for Marine Science and Technology (Centro Andaluz de Ciencia y Tecnología Marina) and Technological Corporation of Andalusia (Corporación Tecnológica de Andalucía). Within the private sphere, although also promoted by public administration, technology parks have been established throughout the Community, such as the Technological Park of Andalucia (Parque Tecnológico de Andalucía) in Campanillas on the outskirts of Málaga, and Cartuja 93 in Seville. Some of these parks specialize in specific sector, such as in aerospace or in food technology. The Andalusian government deployed 600,000 Ubuntu desktop computers in their schools. Media Andalusia has international, national, regional, and local media organizations, which are active gathering and disseminating information (as well as creating and disseminating entertainment). The most notable is the public Radio y Televisión de Andalucía (RTVA), broadcasting on two regional television channels, Canal Sur and Canal Sur 2, four regional radio stations, Canal Sur Radio, Canal Fiesta Radio, Radio Andalucía Información and Canal Flamenco Radio, as well as various digital signals, most notably Canal Sur Andalucía available on cable TV throughout Spain. Newspapers Different newspapers are published for each Andalusian provincial capital, comarca, or important city. Often, the same newspaper organization publishes different local editions with much shared content, with different mastheads and different local coverage. There are also popular papers distributed without charge, again typically with local editions that share much of their content. No single Andalusian newspaper is distributed throughout the region, not even with local editions. In eastern Andalusia the has editions tailored for the provinces of Almería, Granada, and Jaén. Grupo Joly is based in Andalucia, backed by Andalusian capital, and publishes eight daily newspapers there. Efforts to create a newspaper for the entire autonomous region have not succeeded (the most recent as of 2009 was the Diario de Andalucía). The national press (, El Mundo, ABC, etc.) include sections or editions specific to Andalusia. Public television Andalusia has two public television stations, both operated by Radio y Televisión de Andalucía (RTVA): Canal Sur first broadcast on 28 February 1989 (Andalusia Day). Canal Sur 2 first broadcast 5 June 1998. Programming focuses on culture, sports, and programs for children and youth. In addition, RTVA also operates the national and international cable channel Canal Sur Andalucía, which first broadcast in 1996 as Andalucía Televisión. Radio There are four public radio stations in the region, all operated by RTVA: , first broadcast October 1988. , first broadcast September 1998. , first broadcast January 2001. , first broadcast 29 September 2008. Art and culture The patrimony of Andalusia has been shaped by its particular history and geography, as well as its complex flows of population. Andalusia has been home to a succession of peoples and civilizations, many very different from one another, each impacting the settled inhabitants. The ancient Iberians were followed by Celts, Phoenicians and other Eastern Mediterranean traders, Romans, migrating Germanic tribes, Arabs or Berbers. All have shaped the Spanish patrimony in Andalusia, which was already diffused widely in the literary and pictorial genre of the costumbrismo andaluz. In the 19th century, Andalusian culture came to be widely viewed as the Spanish culture par excellence, in part thanks to the perceptions of romantic travellers. In the words of Ortega y Gasset: Arts Andalusia has been the birthplace of many great artists: the classic painters Velázquez, Murillo, and Juan de Valdés Leal; the sculptors Juan Martínez Montañés, Alonso Cano and Pedro de Mena; and such modern painters as Daniel Vázquez Díaz and Pablo Picasso. The Spanish composer Manuel de Falla was from Cádiz and incorporated typical Andalusian melodies in his works, as did Joaquín Turina, from Seville. The great singer Camarón de la Isla was born in San Fernando, Cádiz, and Andrés Segovia who helped shape the romantic-modernist approach to classical guitar, was born in Linares, Jaén. The virtuoso Flamenco guitar player Paco de Lucia who helped internationalize Flamenco, was born in Algeciras, Cadiz. Architecture Since the Neolithic era, Andalusia has preserved important megaliths, such as the dolmens at the Cueva de Menga and the Dolmen de Viera, both at Antequera. Archeologists have found Bronze Age cities at Los Millares and El Argar. Archeological digs at Doña Blanca in El Puerto de Santa María have revealed the oldest Phoenicians city in the Iberian peninsula; major ruins have also been revealed at Roman Italica near Seville. Some of the greatest architecture in Andalusia was developed across several centuries and civilizations, and the region is particularly famous for its Islamic and Moorish architecture, which includes the Alhambra complex, Generalife and the Mosque-Cathedral of Córdoba. The traditional architecture of Andalusia retains its Roman with Arab influences brought by Muslims, with a marked Mediterranean character strongly conditioned by the climate. Traditional urban houses are constructed with shared walls to minimize exposure to high exterior temperatures. Solid exterior walls are painted with lime to minimize the heating effects of the sun. In accord with the climate and tradition of each area, the roofs may be terraces or tiled in the Roman imbrex and tegula style. One of the most characteristic elements (and one of the most obviously influenced by Roman architecture) is the interior patio or courtyard; the patios of Córdoba are particularly famous. Other characteristic elements are decorative (and functional) wrought iron gratings and the tiles known as azulejos. Landscaping—both for common private homes and homes on a more lavish scale—also carries on older traditions, with plants, flowers, and fountains, pools, and streams of water. Beyond these general elements, there are also specific local architectural styles, such as the flat roofs, roofed chimneys, and radically extended balconies of the Alpujarra, the cave dwellings of Guadix and of Granada's Sacromonte, or the traditional architecture of the Marquisate of Zenete. The monumental architecture of the centuries immediately after the Reconquista often displayed an assertion of Christian hegemony through architecture that referenced non-Arab influences. Some of the greatest Renaissance buildings in Andalusia are from the then-kingdom of Jaén: the Jaén Cathedral, designed in part by Andrés de Vandelvira, served as a model for the Cathedral of Malaga and Guadix; the centers of Úbeda and Baeza, dating largely from this era, are UNESCO World Heritage Sites. Seville and its kingdom also figured prominently in this era, as is shown by the Casa consistorial de Sevilla, the Hospital de las Cinco Llagas, or the Charterhouse of Jerez de la Frontera. The Palace of Charles V in Granada is uniquely important for its Italianate purism. Andalusia also has such Baroque-era buildings as the Palace of San Telmo in Seville (seat of the current autonomic presidency), the Church of Our Lady of Reposo in Campillos, and the Granada Charterhouse. Academicism gave the region the Royal Tobacco Factory in Seville and Neoclassicism the nucleus of Cádiz, such as its , Royal Prison, and the Oratorio de la Santa Cueva. Revivalist architecture in the 19th and 20th centuries contributed the buildings of the Ibero-American Exposition of 1929 in Seville, including the Neo-Mudéjar Plaza de España. Andalusia also preserves an important industrial patrimony related to various economic activities. Besides the architecture of the cities, there is also much outstanding rural architecture: houses, as well as ranch and farm buildings and dog houses. Sculpture The Iberian reliefs of Osuna, Lady of Baza, and , the Phoenician sarcophagi of Cádiz, and the Roman sculptures of the Baetic cities such as Italica give evidence of traditions of sculpture in Andalusia dating back to antiquity. There are few significant surviving sculptures from the time of al-Andalus; two notable exceptions are the lions of the Alhambra and of the Maristán of Granada (the Nasrid hospital in the Albaicín). The Sevillian school of sculpture dating from the 13th century onward and the Granadan school beginning toward the end of the 16th century both focused primarily on Christian religious subject matter, including many wooden altarpieces. Notable sculptors in these traditions include Lorenzo Mercadante de Bretaña, , Juan Martínez Montañés, Pedro Roldán, , Jerónimo Balbás, Alonso Cano, and Pedro de Mena. Non-religious sculpture has also existed in Andalusia since antiquity. A fine example from the Renaissance era is the decoration of the Casa de Pilatos in Seville. Nonetheless, non-religious sculpture played a relatively minor role until such 19th-century sculptors as . Painting As in sculpture, there were and the schools of painting. The former has figured prominently in the history of Spanish art since the 15th century and includes such important artists as Zurbarán, Velázquez and Murillo, as well as art theorists such as Francisco Pacheco. The Museum of Fine Arts of Seville and the Prado contain numerous representative works of the Sevillian school of painting. A specific romantic genre known as costumbrismo andaluz depicts traditional and folkloric Andalusian subjects, such as bullfighting scenes, dogs, and scenes from Andalusia's history. Important artists in this genre include Manuel Barrón, José García Ramos, Gonzalo Bilbao and Julio Romero de Torres. The genre is well represented in the private Carmen Thyssen-Bornemisza Collection, part of which is on display at Madrid's Thyssen-Bornemisza Museum and Carmen Thyssen Museum in Málaga. Málaga also has been and is an important artistic center. Its most illustrious representative was Pablo Picasso, one of the most influential artists of the 20th century. The city has a Museum and Natal House Foundation, dedicated to the painter. Literature and philosophy Andalusia plays a significant role in the history of Spanish-language literature, although not all of the important literature associated with Andalusia was written in Spanish. Before 1492, there was the literature written in Andalusian Arabic. Hispano-Arabic authors native to the region include Ibn Hazm, Ibn Zaydún, Ibn Tufail, Al-Mu'tamid, Ibn al-Khatib, Ibn al-Yayyab, and Ibn Zamrak or Andalusian Hebrew poets as Solomon ibn Gabirol. Ibn Quzman, of the 12th century, crafted poems in the colloquial Andalusian language. In 1492 Antonio de Nebrija published his celebrated Gramática de la lengua castellana ("Grammar of the Castilian language"), the first such work for a modern European language. In 1528 Francisco Delicado wrote La lozana andaluza, a novel in the orbit of La Celestina, and in 1599 the Sevillian Mateo Alemán wrote the first part of Guzmán de Alfarache, the first picaresque novel with a known author. The prominent humanist literary school of Seville included such writers as Juan de Mal Lara, Fernando de Herrera, Gutierre de Cetina, Luis Barahona de Soto, Juan de la Cueva, Gonzalo Argote de Molina, and Rodrigo Caro. The Córdoban Luis de Góngora was the greatest exponent of the culteranismo of Baroque poetry in the Siglo de Oro; indeed, the style is often referred to as Góngorismo. Literary Romanticism in Spain had one of its great centers in Andalusia, with such authors as Ángel de Saavedra, 3rd Duke of Rivas, José Cadalso and Gustavo Adolfo Bécquer. Costumbrismo andaluz existed in literature as much as in visual art, with notable examples being the Escenas andaluzas of Serafín Estébanez Calderón and the works of Pedro Antonio de Alarcón. Andalusian authors Ángel Ganivet, Manuel Gómez-Moreno, Manuel and Antonio Machado, and Francisco Villaespesa are all generally counted in the Generation of '98. Also of this generation were the Quintero brothers, dramatists who faithfully captured Andalusian dialects and idiosyncrasies. Also of note, 1956 Nobel Prize-winning poet Juan Ramón Jiménez was a native of Moguer, near Huelva. A large portion of the avant-garde Generation of '27 who gathered at the Ateneo de Sevilla on the 300th anniversary of Góngora's death were Andalusians: Federico García Lorca, Luis Cernuda, Rafael Alberti, Manuel Altolaguirre, Emilio Prados, and 1977 Nobel laureate Vicente Aleixandre. Certain Andalusian fictional characters have become universal archetypes: Prosper Mérimée's gypsy Carmen, P. D. Eastman's Perro, Pierre Beaumarchais's Fígaro, and Tirso de Molina's Don Juan. As in most regions of Spain, the principal form of popular verse is the romance, although there are also strophes specific to Andalusia, such as the soleá or the . Ballads, lullabies, street vendor's cries, nursery rhymes, and work songs are plentiful. Among the philosophers native to the region can be counted Seneca, Avicebron, Maimonides, Averroes, Fernán Pérez de Oliva, Sebastián Fox Morcillo, Ángel Ganivet, Francisco Giner de los Ríos and María Zambrano. Music of Andalusia The music of Andalusia includes traditional and contemporary music, folk and composed music, and ranges from flamenco to rock. Conversely, certain metric, melodic and harmonic characteristics are considered Andalusian even when written or performed by musicians from elsewhere. Flamenco, perhaps the most characteristically Andalusian genre of music and dance, originated in the 18th century, but is based in earlier forms from the region. The influence of the traditional music and dance of the Romani people or Gypsies is particularly clear. The genre embraces distinct vocal (cante flamenco), guitar (toque flamenco), and dance (baile flamenco) styles. The Andalusian Statute of Autonomy reflects the cultural importance of flamenco in its Articles 37.1.18 and 68: Fundamental in the history of Andalusian music are the composers Cristóbal de Morales, Francisco Guerrero, Francisco Correa de Arauxo, Manuel García, Manuel de Falla, Joaquín Turina, and , as well as one of the fathers of modern classical guitar, the guitarist Andrés Segovia. Mention should also be made of the great folk artists of the copla (music) and the cante hondo, such as Rocío Jurado, Lola Flores (La Faraona, "the pharaoh"), Juanito Valderrama and the revolutionary Camarón de la Isla. Prominent Andalusian rock groups include Triana and Medina Azahara. The duo Los del Río from Dos Hermanas had international success with their "Macarena", including playing at a Super Bowl half-time show in the United States, where their song has also been used as campaign music by the Democratic Party. Other notables include the singer, songwriter, and poet Joaquín Sabina, Isabel Pantoja, Rosa López, who represented Spain at Eurovision in 2002, and David Bisbal. On November 16, 2023, Seville will host the 24th Annual Latin Grammy Awards at the FIBES Conference and Exhibition Centre, making Seville the first city outside of the United States to host the Latin Grammy Awards. Film The portrayal of Andalusia in film is often reduced to archetypes: flamenco, bullfighting, Catholic pageantry, brigands, the property-rich and cash-poor señorito andaluz and emigrants. These images particularly predominated from the 1920s through the 1960s, and helped to consolidate a clichéd image of the region. In a very different vein, the province of Almería was the filming location for many Westerns, especially (but by no means exclusively) the Italian-directed Spaghetti Westerns. During the dictatorship of Francisco Franco, this was the extent of the film industry in Andalusia. Nonetheless, Andalusian film has roots as far back as José Val del Omar in the pre-Franco years, and since the Spanish transition to democracy has brought forth numerous nationally and internationally respected directors: (Heart of the Earth), Chus Gutiérrez (Poniente), (Carlos Against the World), Alberto Rodríguez (7 Virgins), Benito Zambrano (Solas), and Antonio Banderas (Summer Rain). Counting together feature films, documentaries, television programs, music videos etc., Andalusia has boomed from 37 projects shooting in 1999 to 1,054 in 2007, with the figure for 2007 including 19 feature films. Although feature films are the most prestigious, commercials and television are currently more economically important to the region. The , headquartered in Córdoba, is a government-run entity in charge of the investigation, collection and diffusion of Andalusian cinematic heritage. Other important contributors to this last activity are such annual film festivals as the Málaga Spanish Film Festival, the most important festival dedicated exclusively to cinema made in Spain, the Seville European Film Festival (SEFF), the International Festival of Short Films—Almería in Short, the Huelva Festival of Latin American Film, the Atlantic Film Show in Cádiz, the Islantilla Festival of Film and Television and the African Film Festival of Tarifa. Culture Customs and society Each sub-region in Andalusia has its own unique customs that represent a fusion of Catholicism and local folklore. Cities like Almería have been influenced historically by both Granada and Murcia in the use of traditional head coverings. The sombrero de Labrador, a worker's hat made of black velvet, is a signature style of the region. In Cádiz, traditional costumes with rural origins are worn at bullfights and at parties on the large estates. The tablao flamenco dance and the accompanying cante jondo vocal style originated in Andalusia and traditionally most often performed by the gypsy (Gitanos). One of the most distinctive cultural events in Andalusia is the Romería de El Rocío in May. It consists of a pilgrimage to the Hermitage of El Rocío in the countryside near Almonte, in honor of the Virgin of El Rocío, an image of the Virgin and Child. In recent times the Romería has attracted roughly a million pilgrims each year. In Jaén, the saeta is a revered form of Spanish religious song, whose form and style has evolved over many centuries. Saetas evoke strong emotion and are sung most often during public processions. Verdiales, based upon the fandango, are a flamenco music style and song form originating in Almogia, near Málaga. For this reason, the Verdiales are sometimes known as Fandangos de Málaga. The region also has a rich musical tradition of flamenco songs, or palos called cartageneras. Seville celebrates Semana Santa, one of the better known religious events within Spain. During the festival, religious fraternities dress as penitents and carry large floats of lifelike wooden sculptures representing scenes of the Passion, and images of the Virgin Mary. Sevillanas, a type of old folk music sung and written in Seville and still very popular, are performed in fairs and festivals, along with an associated dance for the music, the Baile por sevillanas. All the different regions of Andalusia have developed their own distinctive customs, but all share a connectedness to Catholicism as developed during baroque Spain society. Andalusian Spanish Andalusian Spanish is one of the most widely spoken forms of Spanish in Spain, and because of emigration patterns was very influential on American Spanish. Rather than a single dialect, it is really a range of dialects sharing some common features; among these is the retention of more Arabic words than elsewhere in Spain, as well as some phonological differences compared with Standard Spanish. The isoglosses that mark the borders of Andalusian Spanish overlap to form a network of divergent boundaries, so there is no clear border for the linguistic region. A fringe movement promoting an Andalusian language independent from Spanish exists. Religion The territory now known as Andalusia fell within the sphere of influence of ancient Mediterranean mythological beliefs. Phoenician colonization brought the cults of Baal and Melqart; the latter lasted into Roman times as Hercules, mythical founder of both Cádiz and Seville. The Islote de Sancti Petri held the supposed tomb of Hercules, with representations of his Twelve labors; the region was the traditional site of the tenth labor, obtaining the cattle of the monster Geryon. Traditionally, the Pillars of Hercules flank the Strait of Gibraltar. Clearly, the European pillar is the Rock of Gibraltar; the African pillar was presumably either Monte Hacho in Ceuta or Jebel Musa in Morocco. The Roman road that led from Cádiz to Rome was known by several names, one of them being , Hercules route returning from his tenth labor. The present coat of arms of Andalusia shows Hercules between two lions, with two pillars behind these figures. Roman Catholicism is, by far, the largest religion in Andalusia. In 2012, the proportion of Andalusians that identify themselves as Roman Catholic was 78.8%. Spanish Catholic religion constitute a traditional vehicle of Andalusian cultural cohesion, and the principal characteristic of the local popular form of Catholicism is devotion to the Virgin Mary; Andalusia is sometimes known as la tierra de María Santísima ("the land of Most Holy Mary"). Also characteristic are the processions during Holy Week, in which thousands of penitents (known as nazarenos) sing saetas. Andalusia is the site of such pilgrim destinations as the in Andújar and the Hermitage of El Rocío in Almonte. Bullfighting While some trace the lineage of the Spanish Fighting Bull back to Roman times, today's fighting bulls in the Iberian peninsula and in the former Spanish Empire trace back to Andalusia in the 15th and 16th centuries. Andalusia remains a center of bull-rearing and bullfighting: its 227 fincas de ganado where fighting bulls are raised cover . In the year 2000, Andalusia's roughly 100 bullrings hosted 1,139 corridas. The oldest bullring still in use in Spain is the neoclassical Plaza de toros in Ronda, built in 1784. The Andalusian Autonomous Government sponsors the Rutas de Andalucía taurina, a touristic route through the region centered on bullfighting. Festivals The Andalusian festivals provide a showcase for popular arts and traditional costume. Among the most famous of these are the Seville Fair or Feria de Abril in Seville, now echoed by smaller fairs in Madrid and Barcelona, both of which have many Andalusian immigrants; the Feria de Agosto in Málaga; the Feria de Jerez or Feria del Caballo in Jerez; the in Granada; the in Córdoba; the Columbian Festivals (Fiestas Colombinas) in Huelva; the Feria de la Virgen del Mar in Almería; and the in Jaén, among many others. Festivals of a religious nature are a deep Andalusian tradition and are met with great popular fervor. There are numerous major festivals during Holy Week. An annual pilgrimage brings a million visitors to the Hermitage of El Rocío in Almonte (population 16,914 in 2008); similarly large crowds visit the Santuario de Nuestra Señora de la Cabeza in Andújar every April. Other important festivals are the Carnival of Cádiz and the Fiesta de las Cruces or Cruz de mayo in Granada and Córdoba; in Córdoba this is combined with a competition for among the patios (courtyards) of the city. Andalusia hosts an annual festival for the dance of flamenco in the summer-time. Cuisine The Andalusian diet varies, especially between the coast and the interior, but in general is a Mediterranean diet based on olive oil, cereals, legumes, vegetables, fish, dried fruits and nuts, and meat; there is also a great tradition of drinking wine. Fried fish—pescaíto frito—and seafood are common on the coast and also eaten well into the interior under coastal influence. Atlantic bluefin tuna (Thunnus thynnus) from the Almadraba areas of the Gulf of Cádiz, prawns from Sanlúcar de Barrameda (known as langostino de Sanlúcar), and deepwater rose shrimp () from Huelva are all highly prized. Fishing for the transparent goby or chanquete (Aphia minuta), a once-popular small fish from Málaga, is now banned because the techniques used to catch them trap too many immature fish of other species. The mountainous regions of the Sierra Morena and Sierra Nevada produce cured hams, notably including jamón serrano and jamón ibérico. These come from two different types of pig, (jamón serrano from white pigs, the more expensive jamón ibérico from the Black Iberian pig). There are several denominaciones de origen, each with its own specifications including in just which microclimate region ham of a particular denomination must be cured. Plato alpujarreño is another mountain specialty, a dish combining ham, sausage, sometimes other pork, egg, potatoes, and olive oil. Confectionery is popular in Andalusia. Almonds and honey are common ingredients. Many enclosed convents of nuns make and sell pastries, especially Christmas pastries: mantecados, polvorones, pestiños, alfajores, , as well as churros or , meringue cookies (merengadas), and . Cereal-based dishes include migas de harina in eastern Andalusia (a similar dish to couscous rather than the fried breadcrumb based migas elsewhere in Spain) and a sweeter, more aromatic porridge called poleá in western Andalusia. Vegetables form the basis of such dishes as (similar to ratatouille) and the chopped salad known as or . Hot and cold soups based in olive oil, garlic, bread, tomato and peppers include gazpacho, salmorejo, porra antequerana, ajo caliente, sopa campera, or—using almonds instead of tomato—ajoblanco. Wine has a privileged place at the Andalusian table. Andalusian wines are known worldwide, especially fortified wines such as sherry (jerez), aged in soleras. These are enormously varied; for example, dry sherry may be the very distinct fino, manzanilla, amontillado, oloroso, or Palo Cortado and each of these varieties can each be sweetened with Pedro Ximénez or Moscatel to produce a different variety of sweet sherry. Besides sherry, Andalucía has five other denominaciones de origen for wine: D.O. Condado de Huelva, D.O. Manzanilla-Sanlúcar de Barrameda, D.O. Málaga, D.O. Montilla-Moriles, and D.O. Sierras de Málaga. Most Andalusian wine comes from one of these regions, but there are other historic wines without a Protected Geographical Status, for example Tintilla de Rota, Pajarete, Moscatel de Chipiona and Mosto de Umbrete. Andalusia also produces D.O. vinegar and brandy: D.O. Vinagre de Jerez and D.O. Brandy de Jerez. Other traditions The traditional dress of 18th-century Andalusia was strongly influenced by within the context of casticismo (purism, traditionalism, authenticity). The archetype of the majo and maja was that of a bold, pure Spaniard from a lower-class background, somewhat flamboyant in his or her style of dress. This emulation of lower-class dress also extended to imitating the clothes of brigands and Romani ("Gypsy") women. The Museum of Arts and Traditions of Sevilla has collected representative samples of a great deal of the history of Andalusian dress, including examples of such notable types of hat as the sombrero cordobés, sombrero calañés, sombrero de catite and the , as well as the traje corto and traje de flamenca. Andalusia has a great artisan tradition in tile, leather (see Shell cordovan), weaving (especially of the heavy jarapa cloth), marquetry, and ceramics (especially in Jaén, Granada, and Almería), lace (especially Granada and Huelva), embroidery (in Andévalo), ironwork, woodworking, and basketry in wicker, many of these traditions a heritage of the long period of Muslim rule. Andalusia is also known for its dogs, particularly the Andalusian Hound, which was originally bred in the region. Dogs, not just andalusian hounds, are very popular in the region. Andalusian equestrianism, institutionalized in the Royal Andalusian School of Equestrian Art is known well beyond the borders of Spain. The Andalusian horse is strongly built, compact yet elegant, distinguished in the area of dressage and show jumping, and is also an excellent horse for driving. They are known for their elegant "dancing" gait. Sports Team sports In Andalusia, as throughout Spain, football is the predominant sport. Introduced to Spain by British men who worked in mining for Rio Tinto in the province of Huelva, the sport soon became popular with the local population. As Spain's oldest existing football club, Recreativo de Huelva, founded 1889, is known as El Decano ("the Dean"). For the 2023–24 season, five Andalusian clubs compete in Spain's First Division La Liga: Cádiz CF, Real Betis, Sevilla FC, Granada CF and UD Almería. Betis won La Liga in 1934–35 and Sevilla in the 1945–46 season. The other Andalusian teams, Málaga CF play in the Segunda División, Córdoba CF play in the Primera Federación, whilst Recreativo de Huelva, participate in the Segunda Federación, and Marbella FC and Real Jaén participate in the Tercera División. The Andalusia autonomous football team is not in any league, and plays only friendly matches. In recent years, they have played mostly during the Christmas break of the football leagues. They play mostly against national teams from other countries, but would not be eligible for international league play, where Spain is represented by a single national team. In recent decades, basketball has become increasingly popular, with CB Málaga, also known as Unicaja Málaga who have won the Liga ACB in 2007 and the Korać Cup in 2001 and usually play the Euroleague, CB Sevilla (Banca Cívica) and CB Granada competing at the top level in the Liga ACB. Unlike basketball, handball has never really taken off in Andalusia. There is one Andalusian team in the Liga Asobal, Spain's premier handball league: BM Puente Genil, playing in the province of Córdoba. Andalusia's strongest showing in sports has been in table tennis. There are two professional teams: Cajasur Priego TM and Caja Granada TM, the latter being Spain's leading table tennis team, with more than 20 league championships in nearly consecutive years and 14 consecutive Copas del Rey, dominating the Liga ENEBÉ. Cajasur is also one of the league's leading teams. Olympics 220 Andalusian athletes have competed in a total of 16 summer or winter Olympic Games. The first was Leopoldo Sainz de la Maza, part of the silver medal-winning polo team at the 1920 Summer Olympics in Antwerp, Belgium. In all, Andalusians have won six gold medals, 11 silver, and two bronze. Winners of multiple medals include the Córdoban boxer Rafael Lozano (bronze in the 1996 Summer Olympics at Atlanta, Georgia, US, and silver in the 2000 Summer Olympics in Sydney, Australia); sailor Theresa Zabell, Malagueña by adoption (gold medals at Barcelona in 1992 and Atlanta in 1996). Other notable winners have been Granadan tennis player Manuel Orantes (silver in the men's singles of the demonstration tournament in Mexico City in 1968), Jerezano riders Ignacio Rambla and Rafael Soto (silver in dressage in Athens in 2004) and the racewalker Paquillo Fernández from Guadix (silver in Athens in 2004). The largest number of Olympic appearances were by the Malagueña swimmer María Peláez (five appearances), the Granadan skier María José Rienda (four), the Sevillian rider Luis Astolfi (four), and the Sevillian rower Fernando Climent (four, including a silver at Los Angeles, California, US, in 1984. Seville has been a pre-candidate to host the Summer Olympics in two occasions, 2004 and 2008, and Granada has been a pre-candidate to host the winter Olympics; neither has ever succeeded in its candidature. The ski resort of Sierra Nevada, near Granada, has however hosted the 1996 Alpine World Ski Championships, and Granada hosted the 2015 Winter Universiade. Other sports Other sporting events in Andalusia include surfing, kitesurfing and windsurfing competitions at Tarifa, various golf tournaments at courses along the coast, and horse racing and polo at several locations in the interior. Andalusia hosted the 1999 World Championships in Athletics (Seville), the 2005 Mediterranean Games (Almería) and the FIS Alpine World Ski Championships 1996 (Granada), among other major events. There is also the annual Vuelta a Andalucía bicycle road race and the Linares chess tournament. The Circuito de Jerez, located near Jerez de la Frontera, hosts the Spanish motorcycle Grand Prix. Twinning and covenants Andalusia has had a sister region relationship with Buenos Aires (Argentina), since 2001; and with Córdoba (Argentina). Also Andalusia has a collaboration agreement with Guerrero (Mexico).

Azad Jammu and Kashmir (; , ), abbreviated as AJK and colloquially referred to as simply Azad Kashmir, is a region administered by Pakistan as a nominally self-governing entity and constituting the western portion of the larger Kashmir region, which has been the subject of a dispute between India and Pakistan since 1947. Azad Kashmir also shares borders with the Pakistani provinces of Punjab and Khyber Pakhtunkhwa to the south and west, respectively. On its eastern side, Azad Kashmir is separated from the Indian union territory of Jammu and Kashmir (part of Indian-administered Kashmir) by the Line of Control (LoC), which serves as the de facto border between the Indian- and Pakistani-controlled parts of Kashmir. Geographically, it covers a total area of and has a total population of 4,045,366 as per the 2017 national census. The territory has a parliamentary form of government modelled after the British Westminster system, with the city of Muzaffarabad serving as its capital. The President of AJK is the constitutional head of state, while the Prime Minister, supported by a Council of Ministers, is the chief executive. The unicameral Azad Kashmir Legislative Assembly elects both the Prime Minister and President. The territory has its own Supreme Court and a High Court, while the Government of Pakistan's Ministry of Kashmir Affairs and Gilgit-Baltistan serves as a link between itself and Azad Jammu and Kashmir's government, although the autonomous territory is not represented in the Parliament of Pakistan. Northern Azad Kashmir lies in a region that experiences strong vibrations of the earth as a result of the Indian plate underthrusting the Eurasian plate. A major earthquake in 2005 killed at least 100,000 people and left another three million people displaced, causing widespread devastation to the region's infrastructure and economy. Since then, with help from the Government of Pakistan and foreign aid, reconstruction of infrastructure is underway. Azad Kashmir's economy largely depends on agriculture, services, tourism, and remittances sent by members of the British Mirpuri community. Nearly 87% of Azad Kashmiri households own farm property, and the region has the highest rate of school enrollment in Pakistan and a literacy rate of approximately 74%. Name Azad Kashmir (Free Kashmir) was the title of a pamphlet issued by the Muslim Conference party at its 13th general session held in 1945 at Poonch. It is believed to have been a response to the National Conference's Naya Kashmir (New Kashmir) programme. Sources state that it was no more than a compilation of various resolutions passed by the party. But its intent seems to have been to declare that the Muslims of Jammu and Kashmir were committed to the Muslim League's struggle for a separate homeland (Pakistan), and that the Muslim Conference was the sole representative organisation of the Muslims of Kashmir. However, the following year, the party passed an "Azad Kashmir resolution" demanding that the maharaja institute a constituent assembly elected on an extended franchise. According to scholar Chitralekha Zutshi, the organisation's declared goal was to achieve responsible government under the aegis of the maharaja without association with either India or Pakistan. The following year, the party workers assembled at the house of Sardar Ibrahim on 19 July 1947 reversed the decision, demanding that the maharaja accede to Pakistan. Soon afterward, Sardar Ibrahim escaped to Pakistan and led the Poonch rebellion from there, with the assistance of Pakistan's prime minister Liaquat Ali Khan and other officials. Liaquat Ali Khan appointed a committee headed by Mian Iftikharuddin to draft a "declaration of freedom". On 4 October an Azad Kashmir provisional government was declared in Lahore with Ghulam Nabi Gilkar as president under the assumed name "Mr. Anwar" and Sardar Ibrahim as the prime minister. Gilkar travelled to Srinagar and was arrested by the maharaja's government. Pakistani officials subsequently appointed Sardar Ibrahim as the president of the provisional government. Geography The northern part of Azad Jammu and Kashmir encompasses the lower area of the Himalayas, including Jamgarh Peak (). However, Sarwali Peak (6326 m) in Neelum Valley is the highest peak in the state. The region receives rainfall in both the winter and the summer. Muzaffarabad and Pattan are among the wettest areas of Pakistan. Throughout most of the region, the average rainfall exceeds 1400 mm, with the highest average rainfall occurring near Muzaffarabad (around 1800 mm). During the summer season, monsoon floods of the rivers Jhelum and Leepa are common due to extreme rains and snow melting. Climate The southern parts of Azad Kashmir, including the Bhimber, Mirpur, and Kotli districts, have extremely hot weather in the summer and moderate cold weather in the winter. They receive rain mostly in monsoon weather. In the central and northern parts of the state, the weather remains moderately hot in the summer and cold and chilly in the winter. Snowfall also occurs there in December and January. The region receives rainfall in both the winter and the summer. Muzaffarabad and Pattan are among the wettest areas of the state, but they don't receive snow. Throughout most of the region, the average rainfall exceeds 1400 mm, with the highest average rainfall occurring near Muzaffarabad (around 1800 mm). During summer, monsoon floods of the Jhelum and Leepa rivers are common, due to high rainfall and melting snow. History At the time of the Partition of India in 1947, the British abandoned their suzerainty over the princely states, which were left with the options of joining India or Pakistan or remaining independent. Hari Singh, the maharaja of Jammu and Kashmir, wanted his state to remain independent. Muslims in the western districts of the Jammu province (current day Azad Kashmir) and in the Frontier Districts province (current day Gilgit-Baltistan) had wanted to join Pakistan. In Spring 1947, an uprising against the maharaja broke out in Poonch, an area bordering the Rawalpindi division of West Punjab. The maharaja's administration is said to have started levying punitive taxes on the peasantry which provoked a local revolt and the administration resorted to brutal suppression. The area's population, swelled by recently demobilised soldiers following World War II, rebelled against the maharaja's forces and gained control of almost the entire district. Following this victory, the pro-Pakistan chieftains of the western districts of Muzaffarabad, Poonch and Mirpur proclaimed a provisional Azad Jammu and Kashmir government in Rawalpindi on October 3, 1947. Ghulam Nabi Gilkar, under the assumed name "Mr. Anwar," issued a proclamation in the name of the provisional government in Muzaffarabad. However, this government quickly fizzled out with the arrest of Anwar in Srinagar. On October 24, a second provisional government of Azad Kashmir was established at Palandri under the leadership of Sardar Ibrahim Khan. On October 21, several thousand Pashtun tribesmen from North-West Frontier Province poured into Jammu and Kashmir to help with the rebellion against the maharaja's rule. They were led by experienced military leaders and were equipped with modern arms. The maharaja's crumbling forces were unable to withstand the onslaught. The tribesmen captured the towns of Muzaffarabad and Baramulla, the latter of which is northwest of the state capital Srinagar. On October 24, the Maharaja requested military assistance from India, which responded that it was unable to help him unless he acceded to India. Accordingly, on October 26, 1947, Maharaja Hari Singh signed an Instrument of Accession, handing over control of defence, external affairs, and communications to the Government of India in return for military aid. Indian troops were immediately airlifted into Srinagar. Pakistan intervened subsequently. Fighting ensued between the Indian and Pakistani armies, with the two areas of control more or less stabilised around what is now known as the "Line of Control". India later approached the United Nations, asking it to resolve the dispute, and resolutions were passed in favour of the holding of a plebiscite with regard to Kashmir's future. However, no such plebiscite has ever been held on either side, since there was a precondition that required the withdrawal of the Pakistani army along with the non-state elements and the subsequent partial withdrawal of the Indian army. from the parts of Kashmir under their respective control – a withdrawal that never took place. In 1949, a formal cease-fire line separating the Indian- and Pakistani-controlled parts of Kashmir came into effect. Following the 1949 cease-fire agreement with India, the government of Pakistan divided the northern and western parts of Kashmir that it controlled at the time of the cease-fire into the following two separately controlled political entities: Azad Jammu and Kashmir (AJK) – the narrow, southern part, long, with a width varying from . Gilgit–Baltistan formerly called the Federally Administered Northern Areas (FANA) – the much larger political entity to the north of AJK with an area of . In 1955, the Poonch uprising broke out. It was largely concentrated in areas of Rawalakot as well as the rest of Poonch Division. It ended in 1956. At one time under Pakistani control, Kashmir's Shaksgam tract, a small region along the northeastern border of Gilgit–Baltistan, was provisionally ceded by Pakistan to the People's Republic of China in 1963 and now forms part of China's Xinjiang Uygur Autonomous Region. In 1972, the then current border between the Indian and Pakistani controlled parts of Kashmir was designated as the "Line of Control". This line has remained unchanged since the 1972 Simla Agreement, which bound the two countries "to settle their differences by peaceful means through bilateral negotiations". Some political experts claim that, in view of that pact, the only solution to the issue is mutual negotiation between the two countries without involving a third party such as the United Nation. The 1974 Interim Constitution Act was passed by the 48-member Azad Jammu and Kashmir unicameral assembly. In April 1997, the Nawaz Sharif government refused to grant constitutional status to Azad Jammu and Kashmir stating that "'The grant of constitutional rights to these people will amount to unilateral annexation of these areas." Government Azad Jammu and Kashmir (AJK) is nominally a self-governing state, but ever since the 1949 ceasefire between Indian and Pakistani forces, Pakistan has exercised control over the state without incorporating it into Pakistan. Azad Kashmir has its own elected president, prime minister, legislative assembly, high court (with Azam Khan as its present chief justice), and official flag. Azad Kashmir's budget and tax affairs, are dealt with by the Azad Jammu and Kashmir Council rather than by Pakistan's Central Board of Revenue. The Azad Jammu and Kashmir Council is a supreme body consisting of 14 members, 8 from the government of Azad Jammu and Kashmir and 6 from the government of Pakistan. Its chairman/chief executive is the prime minister of Pakistan. Other members of the council are the president and the prime minister of Azad Kashmir (or an individual nominated by her/him) and 6 members of the AJK Legislative Assembly. Azad Kashmir Day is celebrated in Azad Jammu and Kashmir on October 24, which is the day that the Azad Jammu and Kashmir government was created in 1947. Pakistan has celebrated Kashmir Solidarity Day on February 5 of each year since 1990 as a day of protest against India's de facto sovereignty over its State of Jammu and Kashmir. That day is a national holiday in Pakistan. Pakistan observes the Kashmir Accession Day as Black Day on October 27 of each year since 1947 as a day of protest against the accession of Jammu and Kashmir State to India and its military presence in the Indian-controlled parts of Jammu and Kashmir. Brad Adams, the Asia director at the U.S.-based NGO Human Rights Watch said in 2006: "Although 'azad' means 'free,' the residents of Azad Kashmir are anything but; the Pakistani authorities govern the Azad Kashmir government with tight controls on basic freedoms." Scholar Christopher Snedden has observed that despite tight controls, the people of Azad Kashmir have generally accepted whatever Pakistan has done to them, which in any case has varied little from how most Pakistanis have been treated (by Pakistan). According to Christopher Snedden, one of the reasons for this was that the people of Azad Kashmir had always wanted to be part of Pakistan. Consequently, having little to fear from a pro-Pakistan population devoid of options, Pakistan imposed its will through the Federal Ministry of Kashmir Affairs and failed to empower the people of Azad Kashmir, allowing genuine self-government for only a short period in the 1970s. According to the interim constitution that was drawn up in the 1970s, the only political parties that are allowed to exist are those that pay allegiance to Pakistan: "No person or political party in Azad Jammu and Kashmir shall be permitted... activities prejudicial or detrimental to the State's accession to Pakistan." The pro-independence Jammu and Kashmir Liberation Front has never been allowed to contest elections in Azad Kashmir. While the interim constitution does not give them a choice, the people of Azad Kashmir have not considered any option other than joining Pakistan. Except in a legal sense, Azad Kashmir has been fully integrated into Pakistan. Azad Kashmir is home to a vibrant civil society. One of the organizations active in the territory and inside Pakistan is YFK-International Kashmir Lobby Group, an NGO that seeks better India-Pakistan relations through conflict resolution in Kashmir. Development According to the project report by the Asian Development Bank, the bank has set out development goals for Azad Kashmir in the areas of health, education, nutrition, and social development. The whole project is estimated to cost US$76 million. Germany, between 2006 and 2014, has also donated $38 million towards the AJK Health Infrastructure Programme. Administrative divisions The state is administratively divided into three divisions which, in turn, are divided into ten districts. Demographics Population The population of Azad Kashmir, according to the preliminary results of the 2017 Census, is 4.045 million. The website of the AJK government reports the literacy rate to be 74%, with the enrolment rate in primary school being 98% and 90% for boys and girls respectively. The population of Azad Kashmir is almost entirely Muslim. The people of this region culturally differ from the Kashmiris living in the Kashmir Valley of Jammu and Kashmir and are closer to the culture of Jammu. Mirpur, Kotli, and Bhimber are all old towns of the Jammu region. Religion Azad Jammu and Kashmir has an almost entirely Muslim population. According to data maintained by Christian community organizations, there are around 4,500 Christian residents in the region. Bhimber is home to most of them, followed by Mirpur and Muzaffarabad. A few dozen families also live in Kotli, Poonch, and Bagh. However, the Christian community has been struggling to get residential status and property rights in AJK. There is no official data on the total number of Bahais in AJK. Only six Bahai families are known to be living in Muzaffarabad with others living in rural areas. The followers of the Ahmadi faith are estimated to be somewhere between 20,000 and 25,000, and most of them live in Kotli, Mirpur, Bhimber, and Muzaffarabad. Ethnic groups Christopher Snedden writes that most of the native residents of Azad Kashmir are not of Kashmiri ethnicity; rather, they could be called "Jammuites" due to their historical and cultural links with that region, which is coterminous with neighbouring Punjab and Hazara. Because their region was formerly a part of the princely state of Jammu and Kashmir and is named after it, many Azad Kashmiris have adopted the "Kashmiri" identity, whereas in an ethnolinguistic context, the term "Kashmiri" would ordinarily refer to natives of the Kashmir Valley region. The population of Azad Kashmir has strong historical, cultural and linguistic affinities with the neighbouring populations of upper Punjab and Potohar region of Pakistan, whereas the Sudhans have the oral tradition of the Pashtuns. The main communities living in this region are: Gujjars – They are an agricultural tribe and are estimated to be the largest community living in the ten districts of Azad Kashmir. Sudhans – (also known as Sadozai, Sardar) are the second largest tribe, living mainly in the districts of Poonch, Sudhanoti, Bagh, and Kotli in Azad Kashmir, and allegedly originating from the Pashtun areas. Together with the Rajputs, they are the source of most of Azad Kashmir's political leaders. Jats – They are one of the larger communities of AJK and primarily inhabit the districts of Mirpur, Bhimber, and Kotli. A large Mirpuri population lives in the U.K. and it is estimated that more people of Mirpuri origins are now residing in the U.K. than in the Mirpur district, which retains strong ties with the U.K. Rajputs – They are spread across the territory, and they number a little under half a million. Together with the Sundhans, they are the source of most of Azad Kashmir's political class. Mughals – Largely located in the Bagh and Muzaffarabad districts. Awans – A clan with significant numbers in Azad Jammu and Kashmir, living mainly in the Bagh, Poonch, Hattian Bala, and Muzaffarabad. Awans also reside in Punjab and Khyber Pakhtunkhwa in large numbers. Dhund – They are a large clan in Azad Jammu and Kashmir and live mostly in the Bagh, Hattian Bala, and Muzaffarabad districts. They also inhabit Abbottabad and upper Potohar Punjab in large numbers. Kashmiris – Ethnic Kashmiri populations are found in the Neelam Valley and the Leepa Valley (see Kashmiris in Azad Kashmir). Languages The official language of Azad Kashmir is Urdu, while English is used in higher domains. The majority of the population, however, are native speakers of other languages. The foremost among these is Pahari–Pothwari with its various dialects. There are also sizeable communities speaking Kashmiri (mostly in the north), Gujari (throughout the territory), and Dogri (in the south), as well as pockets of speakers of Kundal Shahi, Shina and Pashto. With the exception of Pashto and English, those languages belong to the Indo-Aryan language family. The dialects of the Pahari-Pothwari language complex cover most of the territory of Azad Kashmir. Those are also spoken across the Line of Control in the neighbouring areas of Indian Jammu and Kashmir and are closely related both to Punjabi to the south and Hinko to the northwest. The language variety in the southern districts of Azad Kashmir is known by a variety of names – including Mirpuri, Pothwari and Pahari – and is closely related to the Pothwari proper spoken to the east in the Pothohar region of Punjab. The dialects of the central districts of Azad Kashmir are occasionally referred to in the literature as Chibhali or Punchi, but the speakers themselves usually call them Pahari, an ambiguous name that is also used for several unrelated languages of the lower Himalayas. Going north, the speech forms gradually change into Hindko. Today, in the Muzaffarabad District the preferred local name for the language is Hindko, although it is still apparently more closely related to the core dialects of Pahari. Further north in the Neelam Valley the dialect, locally also known as Parmi, can more unambiguously be subsumed under Hindko. Another major language of Azad Kashmir is Gujari. It is spoken by several hundred thousand people among the traditionally nomadic Gujars, many of whom are nowadays settled. Not all ethnic Gujars speak Gujari, the proportion of those who have shifted to other languages is probably higher in southern Azad Kashmir. Gujari is most closely related to the Rajasthani languages (particularly Mewati), although it also shares features with Punjabi. It is dispersed over large areas in northern Pakistan and India. Within Pakistan, the Gujari dialects of Azad Kashmir are more similar, in terms of shared basic vocabulary and mutual intelligibility, to the Gujar varieties of the neighbouring Hazara region than to the dialects spoken further to the northwest in Khyber Pakhtunkhwa and north in Gilgit. There are scattered communities of Kashmiri speakers, notably in the Neelam Valley, where they form the second-largest language group after speakers of Hindko. There have been calls for the teaching of Kashmiri (particularly in order to counter India's claim of promoting the culture of Kashmir), but the limited attempts at introducing the language at the secondary school level have not been successful, and it is Urdu, rather than Kashmiri, that Kashmiri Muslims have seen as their identity symbol. There is an ongoing process of gradual shift to larger local languages, but at least in the Neelam Valley there still exist communities for whom Kashmiri is the sole mother tongue. There are speakers of Dogri in the southernmost district of Bhimber, where they are estimated to represent almost a third of the district's population. In the northernmost district of Neelam, there are small communities of speakers of several other languages. Shina, which like Kashmiri belongs to the broad Dardic group, is present in two distinct varieties spoken altogether in three villages. Pashto, of the Iranian subgroup and the majority language in the neighbouring province of Khyber Pakhtunkhwa, is spoken in two villages, both situated on the Line of Control. The endangered Kundal Shahi is native to the eponymous village and it is the only language not found outside Azad Kashmir. Economy As of 2021, GDP of Azad Jammu and Kashmir was estimated to be 10 billion pounds, giving per capita an income of £5604. Historically the economy of Azad Kashmir has been agricultural which meant that land was the main source or mean of production. This means that all food for immediate and long-term consumption was produced from the land. The produce included various crops, fruits, vegetables, etc. The land was also the source of other livelihood necessities such as wood, fuel, grazing for animals which then turned into dairy products. Because of this land was also the main source of revenue for the governments whose primary purpose for centuries was to accumulate revenue. Agriculture is a major part of Azad Kashmir's economy. Low-lying areas that have high populations grow crops like barley, mangoes, millet, corn (maize), and wheat, and also raise cattle. In the elevated areas that are less populated and more spread out, forestry, corn, and livestock are the main sources of income. There are mineral and marble resources in Azad Kashmir close to Mirpur and Muzaffarabad. There are also graphite deposits at Mohriwali. There are also reservoirs of low-grade coal, chalk, bauxite, and zircon. Local household industries produce carved wooden objects, textiles, and dhurrie carpets. There is also an arts and crafts industry that produces such cultural goods as namdas, shawls, pashmina, pherans, Papier-mâché, basketry copper, rugs, wood carving, silk and woolen clothing, patto, carpets, namda gubba, and silverware. Agricultural goods produced in the region include mushrooms, honey, walnuts, apples, cherries, medicinal herbs and plants, resin, deodar, kail, chir, fir, maple, and ash timber. The migration to the UK was accelerated and by the completion of Mangla Dam in 1967 the process of 'chain migration' became in full flow. Today, remittances from British Mirpuri community make a critical role in AJK's economy. In the mid-1950s various economic and social development processes were launched in Azad Kashmir. In the 1960s, with the construction of the Mangla Dam in Mirpur District, the Azad Jammu and Kashmir Government began to receive royalties from the Pakistani government for the electricity that the dam provided to Pakistan. During the mid-2000s, a multibillion-dollar reconstruction began in the aftermath of the 2005 Kashmir earthquake. In addition to agriculture, textiles, and arts and crafts, remittances have played a major role in the economy of Azad Kashmir. One analyst estimated that the figure for Azad Kashmir was 25.1% in 2001. With regard to annual household income, people living in the higher areas are more dependent on remittances than are those living in the lower areas. In the latter part of 2006, billions of dollars for development were mooted by international aid agencies for the reconstruction and rehabilitation of earthquake-hit zones in Azad Kashmir, though much of that amount was subsequently lost in bureaucratic channels, leading to considerable delays in help getting to the neediest. Hundreds of people continued to live in tents long after the earthquake. A land-use plan for the city of Muzaffarabad was prepared by the Japan International Cooperation Agency. Tourist destinations in the area include the following: Muzaffarabad, the capital city of Azad Kashmir, is located on the banks of the Jhelum and Neelum rivers. It is from Rawalpindi and Islamabad. Well-known tourist spots near Muzaffarabad are the Red Fort, Pir Chinassi, Patika, Subri Lake and Awan Patti. The Neelam Valley is situated to the north and northeast of Muzaffarabad, The gateway to the valley. The main tourist attractions in the valley are Athmuqam, Kutton, Keran, Changan, Sharda, Kel, Arang Kel and Taobat. Sudhanoti is one of the eight districts of Azad Kashmir in Pakistan. Sudhanoti is located away from Islamabad, the Capital of Pakistan. It is connected with Rawalpindi and Islamabad through Azad Pattan road. Rawalakot city is the headquarters of Poonch District and is located from Islamabad. Tourist attractions in Poonch District are Banjosa Lake, Devi Gali, Tatta Pani, and Toli Pir. Bagh city, the headquarters of Bagh District, is from Islamabad and from Muzaffarabad. The principal tourist attractions in Bagh District are Bagh Fort, Dhirkot, Sudhan Gali, Ganga Lake, Ganga Choti, Kotla Waterfall, Neela Butt, Danna, Panjal Mastan National Park, and Las Danna. The Leepa Valley is located southeast of Muzaffarabad. It is the most charming and scenic place for tourists in Azad Kashmir. New Mirpur City is the headquarters of Mirpur District. The main tourist attractions near New Mirpur City are the Mangla Lake and Ramkot Fort. Education The literacy rate in Azad Kashmir was 62% in 2004, higher than in any other region of Pakistan. The current literacy rate of Azad Kashmir is 76.60% in 2018. And it remained at 79.80% in 2019. According to the 2020–2021 census, the literacy rate in Azad Kashmir was 91.34%.

The Arabian Sea () is a region of sea in the northern Indian Ocean, bounded on the west by the Arabian Peninsula, Gulf of Aden and Guardafui Channel, on the northwest by Gulf of Oman and Iran, on the north by Pakistan, on the east by India, and on the southeast by the Laccadive Sea and the Maldives, on the southwest by Somalia. Its total area is 3,862,000 km2 (1,491,000 sq mi) and its maximum depth is 4,652 meters (15,262 ft). The Gulf of Aden in the west connects the Arabian Sea to the Red Sea through the strait of Bab-el-Mandeb, and the Gulf of Oman is in the northwest, connecting it to the Persian Gulf. Geography The Arabian Sea's surface area is about . The maximum width of the sea is approximately , and its maximum depth is . The biggest river flowing into the sea is the Indus River. The Arabian Sea has two important branches — the Gulf of Aden in the southwest, connecting with the Red Sea through the strait of Bab-el-Mandeb; and the Gulf of Oman to the northwest, connecting with the Persian Gulf. There are also the gulfs of Khambhat and Kutch on the Indian Coast. The Arabian Sea has been crossed by many important marine trade routes since the 3rd or 2nd millennium BCE. Major seaports include Kandla Port, Mundra Port, Pipavav Port, Dahej Port, Hazira Port, Mumbai Port, Nhava Sheva Port (Navi Mumbai), Mormugão Port (Goa), New Mangalore Port and Kochi Port in India, the Port of Karachi, Port Qasim, and the Gwadar Port in Pakistan, Chabahar Port in Iran and the Port of Salalah in Salalah, Oman. The largest islands in the Arabian Sea include Socotra (Yemen), Masirah Island (Oman), Lakshadweep (India) and Astola Island (Pakistan). The countries with coastlines on the Arabian Sea are Yemen, Oman, Pakistan, Iran, India and the Maldives. Limits The International Hydrographic Organization defines the limits of the Arabian Sea as follows: On the west: the eastern limit of the Gulf of Aden. On the north: a line joining Ràs al Hadd, east point of the Arabian Peninsula (22°32'N) and Ràs Jiyùni (61°43'E) on the coast of Pakistan. On the south: a line running from the southern extremity of Addu Atoll in the Maldives, to the eastern extremity of Ràs Hafun (the easternmost point of Africa, 10°26'N). On the east: the western limit of the Laccadive Sea a line running from Sadashivgad on the west coast of India () to Cora Divh () and thence down the west side of the Laccadive and Maldive archipelagos to the most southerly point of Addu Atoll in the Maldives. Border and basin countries Border and basin countries: - 2,500 km coastline - 1,050 km coastline Alternative names The Arabian Sea historically and geographically has been referred to with different names by Arabian and European geographers and travelers, including Erythraean Sea, Indian Sea, Oman sea, Erythraean, Persian Sea in para No 34-35 of the Voyage. In Indian folklore, it is referred to as Darya, Sindhu Sagar, and Arab Samudra. Arab geographers, sailors and nomads used to call this sea by different names, including the Akhdar (Green) Sea, Bahre Fars (Persian Sea), the Ocean Sea, the Hindu sea, the Makran Sea, the sea of Oman; among them Zakariya al-Qazwini, Al-Masudi, Ibn Hawqal and Hafiz-i Abru. They wrote: "The green sea and Indian sea and Persian sea are all one sea and in this sea there are strange creatures." in Iran and Turkey people call it Oman sea. In the Periplus of the Erythraean Sea, as well as in some ancient maps, Erythraean Sea refers to the whole area of the northwestern Indian Ocean, including the Arabian Sea. Trade routes The Arabian Sea has been an important marine trade route since the era of the coastal sailing vessels from possibly as early as the 3rd millennium BCE, certainly the late 2nd millennium BCE through the later days known as the Age of Sail. By the time of Julius Caesar, several well-established combined land-sea trade routes depended upon water transport through the sea around the rough inland terrain features to its north. These routes usually began in the Far East or down river from Madhya Pradesh, India with transshipment via historic Bharuch (Bharakuccha), traversed past the inhospitable coast of modern-day Iran, then split around Hadhramaut, Yemen into two streams north into the Gulf of Aden and thence into the Levant, or south into Alexandria via Red Sea ports such as Axum. Each major route involved transhipping to pack animal caravan, travel through desert country and risk of bandits and extortionate tolls by local potentates. This southern coastal route past the rough country in the southern Arabian Peninsula was significant, and the Egyptian Pharaohs built several shallow canals to service the trade, one more or less along the route of today's Suez Canal, and another from the Red Sea to the Nile River, both shallow works that were swallowed up by huge sand storms in antiquity. Later the kingdom of Axum arose in Ethiopia to rule a mercantile empire rooted in the trade with Europe via Alexandria. Major ports Jawaharlal Nehru Port in Mumbai is the largest port in the Arabian Sea, and the largest container port in India. Major Indian ports in the Arabian Sea are Mundra Port, Kandla Port, Nava Sheva, Kochi Port, Mumbai Port, and Mormugão. The Port of Karachi, Pakistan's largest and busiest seaport lies on the coast of the sea. It is located between the Karachi towns of Kiamari and Saddar. The Gwadar Port of Pakistan is a warm-water, deep-sea port situated at Gwadar in Balochistan at the apex of the Arabian Sea and at the entrance of the Persian Gulf, about 460 km west of Karachi and approximately 75 km (47 mi) east of Pakistan's border with Iran. The port is located on the eastern bay of a natural hammerhead-shaped peninsula jutting out into the Arabian Sea from the coastline. Port of Salalah in Salalah, Oman is also a major port in the area. The International Task Force often uses the port as a base. There is a significant number of warships of all nations coming in and out of the port, which makes it a very safe bubble. The port handled just under 3.5m teu in 2009. Islands There are several islands in the Arabian Sea, with the most important ones being Lakshadweep Islands (India), Socotra (Yemen), Masirah (Oman) and Astola Island (Pakistan). The Lakshadweep Islands (formerly known as the Laccadive, Minicoy, and Aminidivi Islands) is a group of islands in the Laccadive Sea region of Arabian Sea, 200 to 440 km (120 to 270 mi) off the southwestern coast of India. The archipelago is a union territory and is governed by the Union Government of India. The islands form the smallest union territory of India with their total surface area being just . Next to these islands are the Maldives islands. These islands are all part of the Lakshadweep-Maldives-Chagos group of islands. Zalzala Koh was an island which was around for only a few years. After the 2013 earthquake in Pakistan, the mud island was formed. By 2016 the island was finished. Astola Island, also known as Jezira Haft Talar in Balochi, or 'Island of the Seven Hills', is a small, uninhabited island in the northern tip of the Arabian Sea in Pakistan's territorial waters. Socotra, also spelled Soqotra, is the largest island, being part of a small archipelago of four islands. It lies some east of the Horn of Africa and south of the Arabian Peninsula. Masirah and the five Khuriya Muriya Islands are islands off the southeastern coast of Oman. Major Cities There are many major cities and towns in the coast of Arabian Sea. Some of the major cities are Mumbai, Muscat, Karachi, Aden, Salalah, Thiruvananthapuram, Kochi, Kozhikode, Tirur, Kollam, Mangalore, Bhavnagar, Jamnagar, Mogadishu, Gwadar, Abu Dhabi, Mundra, Dubai, Kannur, Panaji, Karwar, Udupi, Ratnagiri, Murdeshwar, Veraval , Colombo, Takamaka, and Dhiffushi. Oxygen minimum zone The Arabian Sea has one of the world's three largest oceanic oxygen minimum zones (OMZ), or “dead zones,” along with the eastern tropical North Pacific and the eastern tropical South Pacific. OMZs have very low levels of oxygen, sometimes undetectable by standard equipment. The Arabian Sea's OMZ has the lowest levels of oxygen in the world, especially in the Gulf of Oman. Causes of the OMZ may include untreated sewage as well as high temperatures on the Indian subcontinent, which increase winds blowing towards India, bringing up nutrients and reducing oxygen in the Arabian Sea's waters. In winter, phytoplankton suited to low-oxygen conditions turn the OMZ bright green. Environment and wildlife The wildlife of the Arabian sea is diverse, and entirely unique because of the geographic distribution. Arabian Sea warming Recent studies by Indian Institute of Tropical Meteorology confirmed that the Arabian Sea is warming monotonously; it possibly is due to by global warming.

Aspartame is an artificial non-saccharide sweetener 200 times sweeter than sucrose and is commonly used as a sugar substitute in foods and beverages. It is a methyl ester of the aspartic acid/phenylalanine dipeptide with brand names NutraSweet, Equal, and Canderel. Aspartame was approved by the US Food and Drug Administration (FDA) in 1974, and then again in 1981, after approval was revoked in 1980. Aspartame is one of the most studied food additives in the human food supply. Reviews by over 100 governmental regulatory bodies found the ingredient safe for consumption at the normal acceptable daily intake (ADI) limit. Uses Aspartame is around 180 to 200 times sweeter than sucrose (table sugar). Due to this property, even though aspartame produces of energy per gram when metabolized, about the same as sucrose, the quantity of aspartame needed to produce a sweet taste is so small that its caloric contribution is negligible. The sweetness of aspartame lasts longer than that of sucrose, so it is often blended with other artificial sweeteners such as acesulfame potassium to produce an overall taste more like that of sugar. Like many other peptides, aspartame may hydrolyze (break down) into its constituent amino acids under conditions of elevated temperature or high pH. This makes aspartame undesirable as a baking sweetener and prone to degradation in products hosting a high pH, as required for a long shelf life. The stability of aspartame under heating can be improved to some extent by encasing it in fats or in maltodextrin. The stability when dissolved in water depends markedly on pH. At room temperature, it is most stable at pH 4.3, where its half-life is nearly 300 days. At pH 7, however, its half-life is only a few days. Most soft-drinks have a pH between 3 and 5, where aspartame is reasonably stable. In products that may require a longer shelf life, such as syrups for fountain beverages, aspartame is sometimes blended with a more stable sweetener, such as saccharin. Descriptive analyses of solutions containing aspartame report a sweet aftertaste as well as bitter and off-flavor aftertastes. Acceptable levels of consumption The acceptable daily intake (ADI) value for food additives, including aspartame, is defined as the "amount of a food additive, expressed on a body weight basis, that can be ingested daily over a lifetime without appreciable health risk". The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Commission's Scientific Committee on Food (later becoming EFSA) have determined this value is 40 mg/kg of body weight per day for aspartame, while the FDA has set its ADI for aspartame at 50 mg/kg per day an amount equated to consuming 75 packets of commercial aspartame sweetener per day to be within a safe upper limit. The primary source for exposure to aspartame in the US is diet soft drinks, though it can be consumed in other products, such as pharmaceutical preparations, fruit drinks, and chewing gum among others in smaller quantities. A can of diet soda contains of aspartame, and, for a adult, it takes approximately 21 cans of diet soda daily to consume the of aspartame that would surpass the FDA's 50 mg/kg of body weight ADI of aspartame from diet soda alone. Reviews have analyzed studies which have looked at the consumption of aspartame in countries worldwide, including the US, countries in Europe, and Australia, among others. These reviews have found that even the high levels of intake of aspartame, studied across multiple countries and different methods of measuring aspartame consumption, are well below the ADI for safe consumption of aspartame. Reviews have also found that populations that are believed to be especially high consumers of aspartame, such as children and diabetics, are below the ADI for safe consumption, even considering extreme worst-case scenario calculations of consumption. In a report released on 10 December 2013, the EFSA said that, after an extensive examination of evidence, it ruled out the "potential risk of aspartame causing damage to genes and inducing cancer" and deemed the amount found in diet sodas safe to consume. Safety and health effects The safety of aspartame has been studied since its discovery, and it is a rigorously tested food ingredient. Aspartame has been deemed safe for human consumption by over 100 regulatory agencies in their respective countries, including the US Food and Drug Administration (FDA), UK Food Standards Agency, the European Food Safety Authority (EFSA), Health Canada, and Food Standards Australia New Zealand. Metabolism and body weight reviews of clinical trials showed that using aspartame (or other non-nutritive sweeteners) in place of sugar reduces calorie intake and body weight in adults and children. A 2017 review of metabolic effects by consuming aspartame found that it did not affect blood glucose, insulin, total cholesterol, triglycerides, calorie intake, or body weight. While high-density lipoprotein levels were higher compared to control, they were lower compared to sucrose. In 2023, the World Health Organization recommended against the use of common non-saccharide sweeteners (NSS), including aspartame, to control body weight or lower the risk of non-communicable diseases, stating: "The recommendation is based on the findings of a systematic review of the available evidence which suggests that use of NSS does not confer any long-term benefit in reducing body fat in adults or children. Results of the review also suggest that there may be potential undesirable effects from long-term use of NSS, such as an increased risk of type 2 diabetes, cardiovascular diseases, and mortality in adults." Phenylalanine High levels of the naturally occurring essential amino acid phenylalanine are a health hazard to those born with phenylketonuria (PKU), a rare inherited disease that prevents phenylalanine from being properly metabolized. Because aspartame contains a small amount of phenylalanine, foods containing aspartame sold in the US must state: "Phenylketonurics: Contains Phenylalanine" on product labels. In the UK, foods that contain aspartame are required by the Food Standards Agency to list the substance as an ingredient, with the warning "Contains a source of phenylalanine". Manufacturers are also required to print "with sweetener(s)" on the label close to the main product name on foods that contain "sweeteners such as aspartame" or "with sugar and sweetener(s)" on "foods that contain both sugar and sweetener". In Canada, foods that contain aspartame are required to list aspartame among the ingredients, include the amount of aspartame per serving, and state that the product contains phenylalanine. Phenylalanine is one of the essential amino acids and is required for normal growth and maintenance of life. Concerns about the safety of phenylalanine from aspartame for those without phenylketonuria center largely on hypothetical changes in neurotransmitter levels as well as ratios of neurotransmitters to each other in the blood and brain that could lead to neurological symptoms. Reviews of the literature have found no consistent findings to support such concerns, and, while high doses of aspartame consumption may have some biochemical effects, these effects are not seen in toxicity studies to suggest aspartame can adversely affect neuronal function. As with methanol and aspartic acid, common foods in the typical diet, such as milk, meat, and fruits, will lead to ingestion of significantly higher amounts of phenylalanine than would be expected from aspartame consumption. Cancer , regulatory agencies, including the FDA and EFSA, and the US National Cancer Institute, have concluded that consuming aspartame is safe in amounts within acceptable daily intake levels and does not cause cancer. These conclusions are based on various sources of evidence, such as reviews and epidemiological studies finding no association between aspartame and cancer. In July 2023, scientists for the International Agency for Research on Cancer (IARC) concluded that there was "limited evidence" for aspartame causing cancer in humans, classifying the sweetener as Group 2B (possibly carcinogenic). The lead investigator of the IARC report stated that the classification "shouldn't really be taken as a direct statement that indicates that there is a known cancer hazard from consuming aspartame. This is really more of a call to the research community to try to better clarify and understand the carcinogenic hazard that may or may not be posed by aspartame consumption." The Joint FAO/WHO Expert Committee on Food Additives (JECFA) added that the limited cancer assessment indicated no reason to change the recommended acceptable daily intake level of 40 mg per kg of body weight per day, reaffirming the safety of consuming aspartame within this limit. The FDA responded to the report by stating: Neurotoxicity symptoms Reviews found no evidence that low doses of aspartame would plausibly lead to neurotoxic effects. A review of studies on children did not show any significant findings for safety concerns with regard to neuropsychiatric conditions such as panic attacks, mood changes, hallucinations, attention deficit hyperactivity disorder (ADHD), or seizures by consuming aspartame. Headaches Reviews have found little evidence to indicate that aspartame induces headaches, although certain subsets of consumers may be sensitive to it. Water quality Aspartame passes through wastewater treatment plants mainly unchanged. Mechanism of action The perceived sweetness of aspartame (and other sweet substances like acesulfame potassium) in humans is due to its binding of the heterodimer G protein-coupled receptor formed by the proteins TAS1R2 and TAS1R3. Aspartame is not recognized by rodents due to differences in the taste receptors. Metabolites Aspartame is rapidly hydrolyzed in the small intestine by digestive enzymes which break aspartame down into methanol, phenylalanine, aspartic acid, and further metabolites, such as formaldehyde and formic acid. Due to its rapid and complete metabolism, aspartame is not found in circulating blood, even following ingestion of high doses over 200 mg/kg. Aspartic acid Aspartic acid (aspartate) is one of the most common amino acids in the typical diet. As with methanol and phenylalanine, intake of aspartic acid from aspartame is less than would be expected from other dietary sources. At the 90th percentile of intake, aspartame provides only between 1% and 2% of the daily intake of aspartic acid. Methanol The methanol produced by aspartame metabolism is unlikely to be a safety concern for several reasons. The amount of methanol produced from aspartame-sweetened foods and beverages is likely to be less than that from food sources already in diets. With regard to formaldehyde, it is rapidly converted in the body, and the amounts of formaldehyde from the metabolism of aspartame are trivial when compared to the amounts produced routinely by the human body and from other foods and drugs. At the highest expected human doses of consumption of aspartame, there are no increased blood levels of methanol or formic acid, and ingesting aspartame at the 90th percentile of intake would produce 25 times less methanol than what would be considered toxic. Chemistry Aspartame is a methyl ester of the dipeptide of the natural amino acids L-aspartic acid and L-phenylalanine. Under strongly acidic or alkaline conditions, aspartame may generate methanol by hydrolysis. Under more severe conditions, the peptide bonds are also hydrolyzed, resulting in free amino acids. Two approaches to synthesis are used commercially. In the chemical synthesis, the two carboxyl groups of aspartic acid are joined into an anhydride, and the amino group is protected with a formyl group as the formamide, by treatment of aspartic acid with a mixture of formic acid and acetic anhydride. Phenylalanine is converted to its methyl ester and combined with the N-formyl aspartic anhydride; then the protecting group is removed from aspartic nitrogen by acid hydrolysis. The drawback of this technique is that a byproduct, the bitter-tasting β-form, is produced when the wrong carboxyl group from aspartic acid anhydride links to phenylalanine, with desired and undesired isomer forming in a 4:1 ratio. A process using an enzyme from Bacillus thermoproteolyticus to catalyze the condensation of the chemically altered amino acids will produce high yields without the β-form byproduct. A variant of this method, which has not been used commercially, uses unmodified aspartic acid but produces low yields. Methods for directly producing aspartyl-phenylalanine by enzymatic means, followed by chemical methylation, have also been tried but not scaled for industrial production. History Aspartame was discovered in 1965 by James M. Schlatter, a chemist working for G.D. Searle & Company. Schlatter had synthesized aspartame as an intermediate step in generating a tetrapeptide of the hormone gastrin, for use in assessing an anti-ulcer drug candidate. He discovered its sweet taste when he licked his finger, which had become contaminated with aspartame, to lift up a piece of paper. Torunn Atteraas Garin participated in the development of aspartame as an artificial sweetener. In 1975, prompted by issues regarding Flagyl and Aldactone, an FDA task force team reviewed 25 studies submitted by the manufacturer, including 11 on aspartame. The team reported "serious deficiencies in Searle's operations and practices". The FDA sought to authenticate 15 of the submitted studies against the supporting data. In 1979, the Center for Food Safety and Applied Nutrition (CFSAN) concluded, since many problems with the aspartame studies were minor and did not affect the conclusions, the studies could be used to assess aspartame's safety. In 1980, the FDA convened a Public Board of Inquiry (PBOI) consisting of independent advisors charged with examining the purported relationship between aspartame and brain cancer. The PBOI concluded aspartame does not cause brain damage, but it recommended against approving aspartame at that time, citing unanswered questions about cancer in laboratory rats. In 1983, the FDA approved aspartame for use in carbonated beverages and for use in other beverages, baked goods, and confections in 1993. In 1996, the FDA removed all restrictions from aspartame, allowing it to be used in all foods. As of May 2023, the FDA stated that it regards aspartame as a safe food ingredient when consumed within the acceptable daily intake level of 50 mg per kg of body weight per day. Several European Union countries approved aspartame in the 1980s, with EU-wide approval in 1994. The Scientific Committee on Food (SCF) reviewed subsequent safety studies and reaffirmed the approval in 2002. The European Food Safety Authority (EFSA) reported in 2006 that the previously established Acceptable daily intake (ADI) was appropriate, after reviewing yet another set of studies. Compendial status British Pharmacopoeia United States Pharmacopeia Commercial uses Under the brand names Equal, NutraSweet, and Canderel, aspartame is an ingredient in approximately 6,000 consumer foods and beverages sold worldwide, including (but not limited to) diet sodas and other soft drinks, instant breakfasts, breath mints, cereals, sugar-free chewing gum, cocoa mixes, frozen desserts, gelatin desserts, juices, laxatives, chewable vitamin supplements, milk drinks, pharmaceutical drugs and supplements, shake mixes, tabletop sweeteners, teas, instant coffees, topping mixes, wine coolers, and yogurt. It is provided as a table condiment in some countries. Aspartame is less suitable for baking than other sweeteners because it breaks down when heated and loses much of its sweetness. NutraSweet Company In 1985, Monsanto bought G.D.Searle, and the aspartame business became a separate Monsanto subsidiary, NutraSweet. In March 2000, Monsanto sold it to J.W. Childs Associates Equity Partners II L.P. European use patents on aspartame expired starting in 1987, and the US patent expired in 1992. Ajinomoto Many aspects of industrial synthesis of aspartame were established by Ajinomoto. In 2004, the market for aspartame, in which Ajinomoto, the world's largest aspartame manufacturer, had a 40% share, was a year, and consumption of the product was rising by 2% a year. Ajinomoto acquired its aspartame business in 2000 from Monsanto for $67 million (equivalent to $ in ). In 2007, Asda was the first British supermarket chain to remove all artificial flavourings and colours in its store brand foods. In 2008, Ajinomoto sued Asda, part of Walmart, for a malicious falsehood action concerning its aspartame product when the substance was listed as excluded from the chain's product line, along with other "nasties". In July 2009, a British court ruled in favor of Asda. In June 2010, an appeals court reversed the decision, allowing Ajinomoto to pursue a case against Asda to protect aspartame's reputation. Asda said that it would continue to use the term "no nasties" on its own-label products, but the suit was settled in 2011 with Asda choosing to remove references to aspartame from its packaging. In November 2009, Ajinomoto announced a new brand name for its aspartame sweetener—AminoSweet. Holland Sweetener Company A joint venture of DSM and Tosoh, the Holland Sweetener Company manufactured aspartame using the enzymatic process developed by Toyo Soda (Tosoh) and sold as the brand Sanecta. Additionally, they developed a combination aspartame-acesulfame salt under the brand name Twinsweet. They left the sweetener industry in 2006, because "global aspartame markets are facing structural oversupply, which has caused worldwide strong price erosion over the last five years", making the business "persistently unprofitable". Competing products Because sucralose, unlike aspartame, retains its sweetness after being heated, and has at least twice the shelf life of aspartame, it has become more popular as an ingredient. This, along with differences in marketing and changing consumer preferences, caused aspartame to lose market share to sucralose. In 2004, aspartame traded at about and sucralose, which is roughly three times sweeter by weight, at around .

AutoCAD is a 2D and 3D computer-aided design (CAD) software application for desktop, web, and mobile developed by Autodesk. It was first released in December 1982 for the CP/M and IBM PC platforms as a desktop app running on microcomputers with internal graphics controllers. Initially a DOS application, subsequent versions were later released for other platforms including Classic Mac OS (1992), Microsoft Windows (1992), web browsers (2010), iOS (2010), macOS (2010), and Android (2011). AutoCAD is a general drafting and design application used in industry by architects, project managers, engineers, graphic designers, city planners and other professionals to prepare technical drawings. After discontinuing the sale of perpetual licenses in January 2016, commercial versions of AutoCAD are licensed through a term-based subscription. History Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal. Origins AutoCAD was derived from a program that began in 1977, and then released in 1979 called Interact CAD, also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle. The first version by Autodesk was demonstrated at the 1982 Comdex and released that December. AutoCAD supported CP/M-80 computers. As Autodesk's flagship product, by March 1986 AutoCAD had become the most ubiquitous CAD program worldwide. The 2022 release marked the 36th major release of AutoCAD for Windows and the 12th consecutive year of AutoCAD for Mac. The native file format of AutoCAD is .dwg. This and, to a lesser extent, its interchange file format DXF, have become de facto, if proprietary, standards for CAD data interoperability, particularly for 2D drawing exchange. AutoCAD has included support for .dwf, a format developed and promoted by Autodesk, for publishing CAD data. Features Compatibility with other software ESRI ArcMap 10 permits export as AutoCAD drawing files. Civil 3D permits export as AutoCAD objects and as LandXML. Third-party file converters exist for specific formats such as Bentley MX GENIO Extension, PISTE Extension (France), ISYBAU (Germany), OKSTRA and Microdrainage (UK); also, conversion of .pdf files is feasible, however, the accuracy of the results may be unpredictable or distorted. For example, jagged edges may appear. Several vendors provide online conversions for free such as Cometdocs. Language AutoCAD and AutoCAD LT are available for English, German, French, Italian, Spanish, Japanese, Korean, Chinese Simplified, Chinese Traditional, Brazilian Portuguese, Russian, Czech, Polish and Hungarian (also through additional language packs). The extent of localization varies from full translation of the product to documentation only. The AutoCAD command set is localized as a part of the software localization. Extensions AutoCAD supports a number of APIs for customization and automation. These include AutoLISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for: products extending AutoCAD functionality to specific fields creating products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D third-party AutoCAD-based application There are a large number of AutoCAD plugins (add-on applications) available on the application store Autodesk Exchange Apps. AutoCAD's DXF, drawing exchange format, allows importing and exporting drawing information. Vertical integration Autodesk has also developed a few vertical programs for discipline-specific enhancements such as: Advance Steel AutoCAD Architecture AutoCAD Electrical AutoCAD Map 3D AutoCAD Mechanical AutoCAD MEP AutoCAD Plant 3D Autodesk Civil 3D Since AutoCAD 2019 several verticals are included with AutoCAD subscription as Industry-Specific Toolset. For example, AutoCAD Architecture (formerly Architectural Desktop) permits architectural designers to draw 3D objects, such as walls, doors, and windows, with more intelligent data associated with them rather than simple objects, such as lines and circles. The data can be programmed to represent specific architectural products sold in the construction industry, or extracted into a data file for pricing, materials estimation, and other values related to the objects represented. Additional tools generate standard 2D drawings, such as elevations and sections, from a 3D architectural model. Similarly, Civil Design, Civil Design 3D, and Civil Design Professional support data-specific objects facilitating easy standard civil engineering calculations and representations. Softdesk Civil was developed as an AutoCAD add-on by a company in New Hampshire called Softdesk (originally DCA). Softdesk was acquired by Autodesk, and Civil became Land Development Desktop (LDD), later renamed Land Desktop. Civil 3D was later developed and Land Desktop was retired. File formats AutoCAD's native file formats are denoted either by a .dwg, .dwt, .dws, or .dxf filename extension. The primary file format for 2D and 3D drawing files created with AutoCAD is .dwg. While other third-party CAD software applications can create .dwg files, AutoCAD uniquely creates RealDWG files. Using AutoCAD, any .dwg file may be saved to a derivative format. These derivative formats include: Drawing Template Files .dwt: New .dwg are created from a .dwt file. Although the default template file is acad.dwt for AutoCAD and acadlt.dwt for AutoCAD LT, custom .dwt files may be created to include foundational configurations such as drawing units and layers. Drawing Standards File .dws: Using the CAD Standards feature of AutoCAD, a Drawing Standards File may be associated to any .dwg or .dwt file to enforce graphical standards. Drawing Interchange Format .dxf: The .dxf format is an ASCII representation of a .dwg file, and is used to transfer data between various applications. Variants AutoCAD LT AutoCAD LT is the lower-cost version of AutoCAD, with reduced capabilities, first released in November 1993. Autodesk developed AutoCAD LT to have an entry-level CAD package to compete in the lower price level. Priced at $495, it became the first AutoCAD product priced below $1000. It was sold directly by Autodesk and in computer stores unlike the full version of AutoCAD, which must be purchased from official Autodesk dealers. AutoCAD LT 2015 introduced Desktop Subscription service from $360 per year; as of 2018, three subscription plans were available, from $50 a month to a 3-year, $1170 license. While there are hundreds of small differences between the full AutoCAD package and AutoCAD LT, there are a few recognized major differences in the software's features: 3D capabilities: AutoCAD LT lacks the ability to create, visualize and render 3D models as well as 3D printing. Network licensing: AutoCAD LT cannot be used on multiple machines over a network. Customization: AutoCAD LT does not support customization with LISP, ARX, .NET and VBA. Management and automation capabilities with Sheet Set Manager and Action Recorder. CAD standards management tools. AutoCAD Mobile and AutoCAD Web AutoCAD Mobile and AutoCAD Web (formerly AutoCAD WS and AutoCAD 360) is an account-based mobile and web application enabling registered users to view, edit, and share AutoCAD files via mobile device and web using a limited AutoCAD feature set — and using cloud-stored drawing files. The program, which is an evolution and combination of previous products, uses a freemium business model with a free plan and two paid levels, including various amounts of storage, tools, and online access to drawings. 360 includes new features such as a "Smart Pen" mode and linking to third-party cloud-based storage such as Dropbox. Having evolved from Flash-based software, AutoCAD Web uses HTML5 browser technology available in newer browsers including Firefox and Google Chrome. AutoCAD WS began with a version for the iPhone and subsequently expanded to include versions for the iPod Touch, iPad, Android phones, and Android tablets. Autodesk released the iOS version in September 2010, following with the Android version on April 20, 2011. The program is available via download at no cost from the App Store (iOS), Google Play (Android) and Amazon Appstore (Android). In its initial iOS version, AutoCAD WS supported drawing of lines, circles, and other shapes; creation of text and comment boxes; and management of color, layer, and measurements — in both landscape and portrait modes. Version 1.3, released August 17, 2011, added support for unit typing, layer visibility, area measurement and file management. The Android variant includes the iOS feature set along with such unique features as the ability to insert text or captions by voice command as well as manually. Both Android and iOS versions allow the user to save files on-line — or off-line in the absence of an Internet connection. In 2011, Autodesk announced plans to migrate the majority of its software to "the cloud", starting with the AutoCAD WS mobile application. According to a 2013 interview with Ilai Rotbaein, an AutoCAD WS product manager for Autodesk, the name AutoCAD WS had no definitive meaning, and was interpreted variously as Autodesk Web Service, White Sheet or Work Space. In 2013, AutoCAD WS was renamed to AutoCAD 360. Later, it was renamed to AutoCAD Web App. Student versions AutoCAD is licensed, for free, to students, educators, and educational institutions, with a 12-month renewable license available. Licenses acquired before March 25, 2020 were a 36-month license, with its last renovation on March 24, 2020. The student version of AutoCAD is functionally identical to the full commercial version, with one exception: DWG files created or edited by a student version have an internal bit-flag set (the "educational flag"). When such a DWG file is printed by any version of AutoCAD (commercial or student) older than AutoCAD 2014 SP1 or AutoCAD 2019 and newer, the output includes a plot stamp/banner on all four sides. Objects created in the Student Version cannot be used for commercial use. Student Version objects "infect" a commercial version DWG file if they are imported in versions older than AutoCAD 2015 or newer than AutoCAD 2018. Ports Windows AutoCAD Release 12 in 1992 was the first version of the software to support the Windows platform - in that case Windows 3.1. After Release 14 in 1997, support for MS-DOS, Unix and Macintosh were dropped, and AutoCAD was exclusively Windows supported. In general any new AutoCAD version supports the current Windows version and some older ones. AutoCAD 2016 to 2020 support Windows 7 up to Windows 10. Mac Autodesk stopped supporting Apple's Macintosh computers in 1994. Over the next several years, no compatible versions for the Mac were released. In 2010 Autodesk announced that it would once again support Apple's Mac OS X software in the future. Most of the features found in the 2012 Windows version can be found in the 2012 Mac version. The main difference is the user interface and layout of the program. The interface is designed so that users who are already familiar with Apple's macOS software will find it similar to other Mac applications. Autodesk has also built-in various features in order to take full advantage of Apple's Trackpad capabilities as well as the full-screen mode in Apple's OS X Lion. AutoCAD 2012 for Mac supports both the editing and saving of files in DWG formatting that will allow the file to be compatible with other platforms besides macOS. AutoCAD 2019 for Mac requires OS X El Capitan or later. AutoCAD LT 2013 was available through the Mac App Store for $899.99. The full-featured version of AutoCAD 2013 for Mac, however, wasn't available through the Mac App Store due to the price limit of $999 set by Apple. AutoCAD 2014 for Mac was available for purchase from Autodesk's web site for $4,195 and AutoCAD LT 2014 for Mac for $1,200, or from an Autodesk authorized reseller. The latest version available for Mac is AutoCAD 2022 as of January 2022.

Aelbert Jacobszoon Cuyp or Cuijp (; 20 October 1620 – 15 November 1691) was one of the leading Dutch Golden Age painters, producing mainly landscapes. The most famous of a family of painters, the pupil of his father, Jacob Gerritszoon Cuyp (1594–1651/52), he is especially known for his large views of Dutch riverside scenes in a golden early morning or late afternoon light. He was born and died in Dordrecht. Biography Known as the Dutch equivalent of Claude Lorrain, he inherited a considerable fortune. His family were all artists, with his uncle Benjamin and grandfather Gerrit being stained glass cartoon designers. Jacob Gerritszoon Cuyp, his father, was a portraitist. Cuyp's father was his first teacher and they collaborated on many paintings throughout his lifetime. Little is known about Aelbert Cuyp's life. Even Arnold Houbraken, a noted historian of Dutch Golden Age paintings and the sole authority on Cuyp for the hundred years following his death, paints a very thin biographical picture. His period of activity as a painter is traditionally limited to the two decades between 1639 and 1660, fitting within the generally accepted limits of the Dutch Golden Age's most significant period, 1640–1665. He is known to have been married to Cornelia Bosman in 1658, a date coinciding so directly with the end of his productivity as a painter that it has been accepted that his marriage played a role in the end of his artistic career. The year after his marriage, Cuyp became the deacon of the reformed church. Houbraken recalled that Cuyp was a devout Calvinist and the fact that when he died, there were no paintings of other artists found in his home. Style The development of Cuyp, who was trained as a landscape painter, may be roughly sketched in three phases based on the painters who most influenced him during that time and the subsequent artistic characteristics that are apparent in his paintings. Generally, Cuyp learned tone from the exceptionally prolific Jan van Goyen, light from Jan Both and form from his father, Jacob Gerritsz Cuyp. Cuyp's "van Goyen phase" can be placed approximately in the early 1640s. Cuyp probably first encountered a painting by van Goyen in 1640 when van Goyen was, as Stephen Reiss points, out "at the height of [his] powers". This is noticeable in the comparison between two of Cuyp's landscape paintings inscribed 1639 where no properly formed style is apparent and the landscape backgrounds he painted two years later for two of his father's group portraits that are distinctly van Goyenesque. Cuyp took from van Goyen the straw yellow and light brown tones that are so apparent in his Dunes (1629) and the broken brush technique also very noticeable in that same work. This technique, a precursor to impressionism, is noted for the short brush strokes where the colors are not necessarily blended smoothly. In Cuyp's River Scene, Two Men Conversing (1641) both of these van Goyen-influenced stylistic elements are noticeable. The next phase in the development of Cuyp's increasingly amalgamated style is due to the influence of Jan Both. In the mid-1640s Both, a native and resident of Utrecht, had just returned to his hometown from a trip to Rome. It is around this same time that Cuyp's style changed fundamentally. In Rome, Both had developed a new style of composition due, at least in part, to his interaction with Claude Lorrain. This new style was focused on changing the direction of light in the painting. Instead of the light being placed at right angles in relation to the line of vision, Both started moving it to a diagonal position from the back of the picture. In this new form of lighting, the artist (and viewer of the painting) faced the sun more or less contre-jour. Both, and subsequently Cuyp, used the advantages of this new lighting style to alter the sense of depth and luminosity possible in a painting. To make notice of these new capabilities, much use was made of elongated shadows. Cuyp was one of the first Dutch painters to appreciate this new leap forward in style and while his own Both-inspired phase was quite short (limited to the mid-1640s) he did, more than any other contemporary Dutch artist, maximize the full chromatic scale for sunsets and sunrises.Cuyp's third stylistic phase (which occurred throughout his career) is based on the influence of his father. While it is assumed that the younger Cuyp did work with his father initially to develop rudimentary talents, Aelbert became more focused on landscape paintings while Jacob was a portrait painter by profession. As has been mentioned and as will be explained in depth below, there are pieces where Aelbert provided the landscape background for his father's portraits. What is meant by stating that Aelbert learned from his father is that his eventual transition from a specifically landscape painter to the involvement of foreground figures is attributed to his interaction with his father Jacob. The evidence for Aelbert's evolution to foreground figure painter is in the production of some paintings from 1645 to 1650 featuring foreground animals that do not fit with Jacob's style. Adding to the confusion regarding Aelbert's stylistic development and the problem of attribution is of course the fact that Jacob's style was not stagnant either. Their converging styles make it difficult to exactly understand the influences each had on the other, although it is clear enough to say that Aelbert started representing large scale forms (something he had not done previously) and placing animals as the focus of his paintings (something that was specific to him). Paintings Sunlight in his paintings rakes across the panel, accentuating small bits of detail in the golden light. In large, atmospheric panoramas of the countryside, the highlights on a blade of meadow grass, the mane of a tranquil horse, the horn of a dairy cow reclining by a stream, or the tip of a peasant's hat are all caught in a bath of yellow ocher light. The richly varnished medium refracts the rays of light like a jewel as it dissolves into numerous glazed layers. Cuyp's landscapes were based on reality and on his own invention of what an enchanting landscape should be.Cuyp's drawings reveal him to be a draftsman of superior quality. Light-drenched washes of golden brown ink depict a distant view of the city of Dordrecht or Utrecht. A Cuyp drawing may look like he intended it to be a finished work of art, but it was most likely taken back to the studio and used as a reference for his paintings. Often the same section of a sketch can be found in several different pictures. Cuyp signed many of his works but rarely dated them, so that a chronology of his career has not been satisfactorily reassembled. A phenomenal number of paintings are ascribed to him, some of which are likely to be by other masters of the golden landscape, such as Abraham Calraet (1642–1722), whose initials A.C. may be mistaken for Cuyp's. However, not everyone appreciates his work and River Landscape (1660), despite being widely regarded as amongst his best work, has been described as having "chocolate box blandness". At the Madrid's Thyssen-Bornemisza Museum most likely, the sole Cuyp's painting in Spanish public collections can be seen, a Landscape with a sunset ca. 1655 with animals. Misattribution of paintings In addition to the scarcely documented and confirmed biography of Cuyp's life, and even more so than his amalgamated style from his three main influences, there are yet other factors that have led to the misattribution and confusion over Aelbert Cuyp's works for hundreds of years. His highly influenced style which incorporated Italianate lighting from Jan Both, broken brush technique and atonality from Jan van Goyen, and his ever-developing style from his father Jacob Gerritsz Cuyp was studied acutely by his most prominent follower, Abraham van Calraet. Calraet mimicked Cuyp's style, incorporating the same aspects, and produced similar landscapes to that of the latter. This made it quite difficult to tell whose paintings were whose. Adding to the confusion is the similar initials between the two and the inconsistent signing of paintings which were produced by Cuyp's studio. Although Aelbert Cuyp signed many of his paintings with a script "A. Cuyp" insignia, many paintings were left unsigned (not to mention undated) after being painted, and so a similar signature was added later on, presumably by collectors who inherited or discovered the works. Furthermore, many possible Cuyp paintings were not signed but rather initialed "A. C." referring to his name. However, Abraham van Calraet could also have used the same initials to denote a painting. Although this is unlikely (as Calraet would likely have signed his paintings "A. v.C."), this brings up the question of how paintings were signed to show ownership. Most original Cuyp paintings were signed by him, and in the script manner in which his name was inscribed. This would denote that the painting was done almost entirely by him. Conversely, paintings which came out of his workshop that were not necessarily physically worked on by Cuyp but merely overseen by him technically, were marked with A.C. to show that it was his instruction which saw the paintings' completion. Cuyp's pupils and assistants often worked on paintings in his studio, and so most of the work of a painting could be done without Cuyp ever touching the canvas, but merely approving its finality. Hence, the initialed inscription rather than a signature. Common among the mislabeled works are all of the reasons identified for misattributing Cuyp's works: the lack of biography and chronology of his works made it difficult to discern when paintings were created (making it difficult to pinpoint an artist); contentious signatures added to historians' confusion as to who actually painted the works; and the collaborations and influences by different painters makes it hard to justify that a painting is genuinely that of Aelbert Cuyp; and finally, accurate identification is made extremely difficult by the fact that this same style was copied (rather accurately) by his predecessor. As it turns out, even the historians and expert researchers have been fooled and forced to reassess their conclusions over "Cuyp's" paintings over the years. Later life After he married Cornelia Boschman in 1658, the number of works produced by him declined almost to nothing. This may have been because his wife was a very religious woman and a not very big patron of the arts. It could also be that he became more active in the church under his wife's guidance. He was also active as deacon and elder of the Reformed Church. Legacy Though long lacking a modern biography, and with the chronology of his works rather unclear, his style emerged from various influences and makes his works distinctive, although his collaborations with his father and works by his imitators often make attributions uncertain. His follower Abraham van Calraet represents a particular problem, and the signatures on paintings are not to be relied on. The Rijksmuseum has reattributed many works to other painters; Abraham van Calraet does not even appear in a Museum catalogue until 1926, and even then he was not given his own entry.
