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 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 seize control of Cyprus was met by military intervention from Turkey, which soon controlled more than a third of the island. In 1983, the Turkish-held area declared itself the "Turkish Republic of Northern Cyprus" ("TRNC"), but it is recognized only by Turkey. The election of a new Cypriot president in 2008 served as the impetus for the UN to encourage both the Turkish and Cypriot Governments to reopen unification negotiations. In September 2008, the leaders of the Greek Cypriot and Turkish Cypriot communities started negotiations under UN auspices aimed at reuniting the divided island. Seventy-eight percent of its citizens are Greek Orthodox. Cyprus began printing stamps in 1845 and Mary first appeared on Cyprus stamps in 1968.
