The Cyprus problem, also known as the Cyprus conflict, Cyprus issue, Cyprus dispute, or Cyprus question, is an ongoing dispute between the Greek Cypriot community which runs the Republic of Cyprus and the Turkish Cypriot community in the north of the island, where troops of the Republic of Turkey are deployed. This dispute is an example of a protracted social conflict. The Cyprus dispute's causes stem from ethnic Greek nationalist ideology, Greek-Cypriot sentiment, the Megali Idea and Enosis, and some of the ethnic Turkish peoples' desire for the partition of the island of Cyprus through Taksim as a means of protection of their people by what they considered to be the threat of Greek-Cypriots.
