Population exchange between Greece and Turkey

During the Treaty of Lausanne on 1923, the population exchange between Greece and Turkey took place at the suggestion of the Greek government. The exchange took place according to religious criteria. The expulsion affected the Greek Orthodox citizens of Anatolia and Izmir in Turkey and the Muslim inhabitants of Greece and Crete. The exceptions were of Greeks living in Istanbul, East Thrace and on the islands of Gökçeada and Bozcaada in Turkey. Muslims living in Western Thrace in Greece and Islands like Rhodes were allowed to stay.
