Greco-Turkish War (1919–1922)
The Greek campaign was launched primarily because the western Allies, particularly British Prime Minister David Lloyd George, had promised Greece territorial gains at the expense of the Ottoman Empire, recently defeated in World War I. The armed conflict started when the Greek forces landed in Smyrna (now Izmir), on 15 May 1919. They advanced inland and took control of the western and northwestern part of Anatolia, including the cities of Manisa, Balıkesir, Aydın, Kütahya, Bursa and Eskişehir. Their advance was checked at the Battle of Sakarya in 1921 by forces of the Turkish national movement. The Greek front collapsed with the Turkish counter-attack in August 1922, and the war effectively ended with the recapture of Smyrna by the Turkish forces and the Great Fire of Smyrna.
Greeks in Turkey
During the Greco-Turkish War, a conflict which followed the Hellenic occupation of Smyrna in May 1919 and continued until the Great Fire of Smyrna in September 1922, atrocities perpetrated by both the Hellenic and Turkish armies. For the massacres that occurred during the Greco-Turkish War of 1919–1922, British historian Arnold J. Toynbee wrote that it was the Greek landings that created the Turkish National Movement led by Mustafa Kemal: "The Greeks of 'Pontus' and the Turks of the Greek occupied territories, were in some degree victims of Mr. Venizelos's and Mr. Lloyd George's original miscalculations at Paris."
