The Turkish invasion of Cyprus launched on 20 July 1974, was a Turkish military invasion of the island country of Cyprus, which was carried out following the 1974 Cypriot coup d'état. In August 1974 a further Turkish invasion resulted in the capture of approximately 40% of the island. The ceasefire line from August 1974 became the United Nations Buffer Zone in Cyprus and is commonly referred to as the Green Line. This action ended in the partition of Cyprus along the UN-monitored Green Line, which still divides Cyprus, and the formation of a de facto autonomous Turkish Cypriot administration in the north.
