This article covers the civilian casualties and displacements that occurred between 1963 and 1975 – from the outbreak of the intercommunal fighting until the end of displacements following the Turkish invasion of Cyprus.
On 21 December 1963, serious violence erupted in Nicosia when a Greek Cypriot police patrol, checking identification documents, stopped a Turkish Cypriot couple on the edge of the Turkish quarter. A hostile crowd gathered, shots were fired, and three people (two Turkish Cypriots and one Greek Cypriot) were killed. As the news spread, members of underground organizations began firing and taking hostages. North of Nicosia, Turkish forces occupied a strong position at St. Hilarion Castle, dominating the road to Kyrenia on the northern coast. The road became a principal combat area as both sides fought to control it. Much intercommunal fighting occurred in Nicosia along the line separating the Greek and Turkish quarters of the city (known later as the Green Line).
Severe intercommunal fighting occurred in March and April 1964. When the worst of the fighting was over, Turkish Cypriots began moving from isolated rural areas and mixed villages into enclaves. Turkish Cypriots state that the hostilities forced such an amalgamation while the Greek Cypriots state that the Turkish Cypriots did so without any pressure from them, but rather by the Turkish Cypriot paramilitary organization TMT so that to apply uniformity. It is believed by progressive Cypriots that both events occurred. Before long, a substantial portion of the island's Turkish Cypriot population was crowded into the Turkish quarter of Nicosia and other enclaves, in tents and hastily constructed shacks. Slum conditions resulted from the serious overcrowding.
Attempts of the Cypriot National Guard under control of General George Grivas, who claimed to be acting under a mandate given to Cyprus by the UN, to re-capture a beach-head at the Kokkina/Erenköy enclave which the Turkish Cypriots claimed was their last link with the outside world but the Greek Cypriots feared would be used as a landing post for Turkish mainland forces, caused an intervention by the Turkish Airforce. On 8 – 9 August, Turkey bombed the Tylliria area for two days, resulting in the death of 33 Greek Cypriots and 230 injuries.
