The United Nations Peacekeeping Force in Cyprus (UNFICYP) was established in 1964 to prevent a recurrence of fighting between the Greek Cypriots and Turkish Cypriots and to contribute to the maintenance and restoration of law and order and a return to normal conditions.^[1] After the 1974 Greek coup-d'etat and the Turkish invasion of Cyprus, the UN Security Council extended and expanded the mission to prevent that Cyprus dispute turning into war.
