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.
Greek–Turkish relations
During the Crimean War (1854 to 1856), Britain and France restrained Greece from attacking the Ottomans, by occupying Piraeus. Again during the Russo-Turkish War of 1877 the Greeks were keen to join in with the objective of territorial expansion, but Greece was unable to take any effective part in the war. Nevertheless, after the Congress of Berlin, in 1881 Greece was given most of Thessaly and part of Epirus. Also, in 1854-1896, there were revolts in the Ottoman Empire by the Greek population in Thessaly, Macedonia, Epirus.
