Several distinct periods of intercommunal violence involving the Greek and Turkish Cypriots marked mid-20th century Cyprus. These included the Cyprus Emergency of 1955–59 during British rule, the post-independence Cyprus crisis of 1963–64, and the Cyprus crisis of 1967. Hostilities culminated in the 1974 de facto division of the island along the Green Line following the coup organized by US-backed Greek junta (1974 Cypriot coup d'état), and the Turkish invasion of Cyprus. The region has been relatively peaceful since then, but the Cyprus dispute has continued, with various attempts to solve it diplomatically having been generally unsuccessful.
