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.

According to some historians, it was the Greek occupation of Smyrna that created the Turkish National movement. Arnold J. Toynbee argues: "The war between Turkey and Greece which burst out at this time was a defensive war for safeguarding of the Turkish homelands in Anatolia. It was a result of the Allied policy of imperialism operating in a foreign state, the military resources and powers of which were seriously under-estimated; it was provoked by the unwarranted invasion of a Greek army of occupation." According to others, the landing of the Greek troops in Smyrna was part of Eleftherios Venizelos's plan, inspired by the Megali Idea, to liberate the large Greek populations in the Asia Minor. Smyrna up to the Great Fire of Smyrna had a bigger Greek population than the Greek capital, Athens. Athens, before the Population exchange between Greece and Turkey, had a population of 473,000, while Smyrna, according to Ottoman sources, in 1910, had a Greek population exceeding 629,000.
