On 2 August 1975, in the negotiations in Vienna, a population exchange agreement was signed between community leaders Rauf Denktaş and Glafcos Clerides under the auspices of United Nations. On the basis of the Agreement, 196,000 Greek Cypriots living in the north were exchanged for 42,000 Turkish Cypriots living in the south (the number of settlers was disputed). The Orthodox Greek Cypriots in Rizokarpaso, Agios Andronikos and Agia Triada chose to stay in their villages, as did also Catholic Maronites in Asomatos, Karpasia and Kormakitis. Approximately 1,500 Greek Cypriots and 500 Turkish Cypriots remain missing. The invasion led to the formation of the first sovereign administrative body of Northern Cyprus in August 1974, the Autonomous Turkish Cypriot Administration.
