Grande Idée
The Greek army evacuated not only Anatolia, but also Eastern Thrace and the islands of Imbros and Tenedos in accordance with the terms of the Treaty of Lausanne (1923). A population exchange between Greece and Turkey was agreed between the two countries, with over 1.5 million Christians and almost half a million Muslims being uprooted. This catastrophe marked the end of the "Megali Idea", and left Greece financially exhausted, demoralized, and having to house and feed a proportionately huge number of Greek refugees.
