A coup d'état in 1974, performed as part of an attempt to annexe the island to Greece, prompted the Turkish invasion of Cyprus. This resulted in the eviction of much of the north's Greek Cypriot population, the flight of Turkish Cypriots from the south, and the partitioning of the island, leading to a unilateral declaration of independence by the north in 1983. Due to its lack of recognition, Northern Cyprus is heavily dependent on Turkey for economic, political and military support.
