Greece's defeat in the Greco-Turkish War and the resulting Armistice of Mudanya in October 1922 prompted Eleftherios Venizelos to petition the League of Nations for a formal population exchange. By that point, most surviving Greek Orthodox inhabitants of Turkey had already fled genocidal violence, and Turkey sought to formalize their departure while resettling depopulated villages with Muslims from Greece.
The Convention Concerning the Exchange of Greek and Turkish Populations was signed at Lausanne on 30 January 1923. It mandated a compulsory, religion-based exchange affecting approximately 1.22 million Greek Orthodox Christians from Turkey and 355,000–400,000 Muslims from Greece. Fridtjof Nansen oversaw the arrangements. The exchange covered native citizens, including veterans and Turkish-speaking Christians, who had no representation in the negotiating parties.
The exchange resulted in the near-total removal of indigenous Greek Orthodox communities from Turkey and most Muslim communities from Greece, permanently altering the demographic character of both nations. Scholars have characterized it as a legalized form of mutual ethnic cleansing, though some argue it prevented further mass atrocities against the remaining Greek Orthodox population in Turkey.
