The Genocide of Greeks living in the lands south of the Black Sea took place between 1914 and 1923. The Greek genocide, part of which is known as the Pontic genocide, was the systematic ethnic cleansing of the Christian Ottoman Greek population from its historic homeland. It was instigated by the government of the Ottoman Empire against the Greek population and included massacres, forced deportations involving death marches, summary expulsions, arbitrary execution, and the destruction of Christian Orthodox cultural and religious monuments. By the end of the Greco-Turkish War most of the Greeks of Asia Minor had either fled or had been killed. Those remaining were transferred to Greece under the terms of a population exchange agreement, which formalized the exodus and barred the return of the refugees. Pontian and Anatolian Greeks were victims of a broader Turkish genocidal project aimed at all Christian minorities in the Ottoman Empire. A total of more than 3.5 million Greeks, Armenians, and Assyrians were killed from roughly 1914 to 1923. Of this, as many as 1.5 million Greeks may have died either from massacre or exposure. About one million had migrated, some voluntarily but most under coercion. Presently, a miniscule Greek population remains in Turkey. Check out the full article on Greek City Times.
