Cyprus was placed under British administration based on Cyprus Convention in 1878 and formally annexed by Britain in 1914. Even though Turkish Cypriots made up only 18% of the population, the partition of Cyprus and creation of a Turkish state in the north became a policy of Turkish Cypriot leaders and Turkey in the 1950s. Turkish leaders for a period advocated the annexation of Cyprus to Turkey as Cyprus was considered an "extension of Anatolia" by them; while since the 19th century, the majority Greek Cypriot population and its Orthodox church had been pursuing union with Greece, which became a Greek national policy in the 1950s. Following nationalist violence in the 1950s, Cyprus was granted independence in 1960. In 1963, the 11-year intercommunal violence between Greek Cypriots and Turkish Cypriots started, which displaced more than 25,000 Turkish Cypriots and brought the end of Turkish Cypriot representation in the republic. On 15 July 1974, a coup d'état was staged by Greek Cypriot nationalists and elements of the Greek military junta in an attempt at enosis, the incorporation of Cyprus into Greece. This action precipitated the Turkish invasion of Cyprus, which led to the capture of the present-day territory of Northern Cyprus the following month, after a ceasefire collapsed, and the displacement of over 150,000 Greek Cypriots and 50,000 Turkish Cypriots. A separate Turkish Cypriot state in the north was established in 1983. These events and the resulting political situation are matters of a continuing dispute.
