Cyprus was placed under the UK's administration based on the Cyprus Convention in 1878 and was formally annexed by the UK in 1914. The future of the island became a matter of disagreement between the two prominent ethnic communities, Greek Cypriots, who made up 77% of the population in 1960, and Turkish Cypriots, who made up 18% of the population. From the 19th century onwards, the Greek Cypriot population pursued "enosis", union with Greece, which became a Greek national policy in the 1950s. The Turkish Cypriot population initially advocated the continuation of the British rule, then demanded the annexation of the island to Turkey, and in the 1950s, together with Turkey, established a policy of "taksim", the partition of Cyprus and the creation of a Turkish polity in the north. Following nationalist violence in the 1950s, Cyprus was granted independence in 1960. The crisis of 1963–64 brought further intercommunal violence between the two communities, displaced more than 25,000 Turkish Cypriots into enclaves 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". This action precipitated the Turkish invasion of Cyprus on 20 July, which led to the capture of the present-day territory of Northern Cyprus and the displacement of over 150,000 Greek Cypriots and 50,000 Turkish Cypriots. A separate Turkish Cypriot state in the north was established by unilateral declaration in 1983; the move was widely condemned by the international community, with Turkey alone recognising the new state. These events and the resulting political situation are matters of a continuing dispute.
