Turkish invasion of Cyprus
Turkey invaded Cyprus on 20 July 1974 in an operation that progressed in two phases over the following month. Taking place upon a background of intercommunal violence between Greek and Turkish Cypriots, and in response to a Greek junta-sponsored Cypriot coup d'état five days earlier, it led to the Turkish capture and occupation of the northern part of the island.
