The Cyprus problem, also known as the Cyprus conflict, Cyprus issue, Cyprus dispute, or Cyprus question, is an ongoing dispute between the Greek Cypriot and the Turkish Cypriot community in the north of the island of Cyprus, where troops of the Republic of Turkey are deployed. This dispute is an example of a protracted social conflict. The Cyprus dispute began after the Greek Cypriot community challenged the British occupation of the island in 1955, the 1974 Cypriot coup d'état executed by the Cypriot National Guard and sponsored by the Greek military junta, and the ensuing Turkish military invasion of the island, and hence the presence of Turkish soldiers, despite a legal reinstatement of a stable government. The desire of some of the ethnic Turkish people for the partition of the island of Cyprus through Taksim, the desire of some of the ethnic Greek people for the unification with Greece (Enosis), and mainland Turkish nationalists settling in as a show of force as a supposed means of protecting their people from what they considered to be the threat of Greek Cypriots also plays a role in the dispute.
Initially, with the occupation of the island by the British Empire from the Ottoman Empire in 1878 and subsequent annexation in 1914, the "Cyprus dispute" referred to general conflicts between Greek and Turkish islanders.
