A former British colony, Cyprus became independent in 1960 following years of resistance to British rule. Tensions between the Greek Cypriot majority and Turkish Cypriot minority communities came to a head in December 1963, when violence broke out in the capital of Nicosia. Despite the deployment of UN peacekeepers in 1964, sporadic intercommunal violence continued, forcing most Turkish Cypriots into enclaves throughout the island. In 1974, a Greek Government-sponsored attempt to overthrow the elected president of Cyprus was met by military intervention from Turkey, which soon controlled more than a third of the island. In 1983, the Turkish Cypriot administered area declared itself the "Turkish Republic of Northern Cyprus" ("TRNC"), but it is recognized only by Turkey. A UN-mediated agreement, the Annan Plan, failed to win approval by both communities in 2004. In February 2014, after a hiatus of nearly two years, the leaders of the two communities resumed formal discussions under UN auspices aimed at reuniting the divided island. The most recent round of negotiations to reunify the island were suspended in July 2017 after failure to achieve a breakthrough. The entire island entered the EU on 1 May 2004, although the EU acquis - the body of common rights and obligations - applies only to the areas under the internationally recognized government, and is suspended in the area administered by Turkish Cypriots. However, individual Turkish Cypriots able to document their eligibility for Republic of Cyprus citizenship legally enjoy the same rights accorded to other citizens of EU states.
