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.
Greco-Turkish War (1919–1922)
One of the main motivations for initiating the war was to realize the Megali (Great) Idea, a core concept of Greek nationalism. The Megali Idea was an irredentist vision of a restoration of a Greater Greece on both sides of the Aegean that would incorporate territories with Greek populations outside the borders of the Kingdom of Greece, which was initially very small — roughly half the size of the present-day Republic of Greece. From the time of Greek independence from the Ottoman Empire in 1830, the Megali Idea had played a major role in Greek politics. Greek politicians, since the independence of the Greek state, had made several speeches on the issue of the "historic inevitability of the expansion of the Greek Kingdom." For instance, Greek politician Ioannis Kolettis voiced this conviction in the assembly in 1844: "There are two great centres of Hellenism. Athens is the capital of the Kingdom. Constantinople is the great capital, the City, the dream and hope of all Greeks."
