Example Input: Question: Who were the leaders of the group that staged a coup against the Cypriot President? Passage:Turkish Cypriot migration to Australia began in the late 1940s; they were the only Muslims acceptable under the White Australia Policy. Prior to 1940, the Australian Census recorded only three settlers from Cyprus that spoke Turkish as their primary language, although many Turkish Cypriot arrivals spoke Greek as their first language. A further 66 Turkish Cypriots arrived in Australia in the late 1940s, marking the beginning of a Turkish Cypriot immigration trend to Australia. By 1947-1956 there were 350 Turkish Cypriot settlers who were living in Australia. Between 1955-1960, the Turkish Cypriots felt vulnerable in Cyprus as they had cause for concern about the political future of the island when the Greek Cypriots attempted to overthrow the British government and unite Cyprus with Greece (known as "enosis"). After a failed attempt by the Greek Cypriots, the right-wing party, EOKA, reformed itself from 1963–1974 and launched a series of attacks. This resulted in the exodus of more Turkish Cypriots to Australia in fear for their lives. Early Turkish Cypriot immigrants to Australia found jobs working in factories, out in the fields, or building national infrastructure. Some Turkish Cypriots also became entrepreneurs and established their own businesses once they had saved enough money. By 1974, an exodus of more Turkish Cypriots to Australia occurred due to fears that the island would unite with Greece when the Greek military junta staged a coup d'état against the Cypriot President, with the help of EOKA B. Immigration to Australia has continued since as a result of an economic embargo which was launched against the Turkish Cypriots by the Greek Cypriot controlled Republic of Cyprus due to the establishment of the Turkish Republic of Northern Cyprus (TRNC) which has remained internationally unrecognised except by Turkey.
