In the aftermath of World War I , Greece attempted further expansion into Asia Minor , a region with a large native Greek population at the time , but was defeated in the Greco-Turkish War of 1919 – 1922 , contributing to a massive flight of Asia Minor Greeks . These events overlapped , with both happening during the Greek genocide ( 1914 – 1922 ) , a period during which , according to various sources , Ottoman and Turkish officials contributed to the death of several hundred thousand Asia Minor Greeks , along with similar numbers of Assyrians and a rather larger number of Armenians . The resultant Greek exodus from Asia Minor was made permanent , and expanded , in an official Population exchange between Greece and Turkey . The exchange was part of the terms of the Treaty of Lausanne which ended the war
