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.
Megali Idea
The military defeat of Greece in the Greco-Turkish war cost it small territorial losses along the border line in northern Thessaly, and a large sum of financial reparations that wrecked Greece's economy for years, while giving no lasting solution to the Cretan Question. The Great Powers (Britain, France, Russia, and Italy) in order to prevent future clashes and trying to avoid the creation of a revanchist climate in Greece, imposed what they thought of as the final solution on the Cretan Question: Crete was proclaimed an autonomous "Cretan State". The four Great Powers assumed the administration of Crete; and, in a decisive diplomatic victory for Greece, Prince George of Greece (second son of King George I) became High Commissioner.
