Greek genocide
The Greek genocide, including the Pontic genocide, was the systematic killing of the Christian Ottoman Greek population carried out in Anatolia during World War I and its aftermath (1914–1922) on the basis of their religion and ethnicity. It was instigated by the government of the Ottoman Empire and the Turkish national movement against the indigenous Greek population of the Empire and it included massacres, forced deportations involving death marches, summary expulsions, arbitrary execution, and the destruction of Eastern Orthodox cultural, historical, and religious monuments. According to various sources, several hundred thousand Ottoman Greeks died during this period. Most of the refugees and survivors fled to Greece (adding over a quarter to the prior population of Greece). Some, especially those in Eastern provinces, took refuge in the neighbouring Russian Empire.
By late 1922, most of the Greeks of Asia Minor had either fled or had been killed. Those remaining were transferred to Greece under the terms of the later 1923 population exchange between Greece and Turkey, which formalized the exodus and barred the return of the refugees. Other ethnic groups were similarly attacked by the Ottoman Empire during this period, including the Assyrian genocide and the Armenian genocide, and some scholars and organizations have recognized these events as part of the same genocidal policy
