The Greco-Turkish War (1919-1922) was a series of military conflicts between the Greeks and the Turks which occurred after World War I when the Greeks attempted to expand their territory into eastern Thrace and the district of Smyrna.
These territories were given to Greeks as part of the Treaty of Sèvres with the dissolution of the Ottoman Empire, but was rejected by nationalist Turks leading to the war and a series of bloody massacres committed by both sides.
