Greek Asia Minor Campaign   5.1919-10.1922

The Greco-Turkish War of 1919–1922, also called the War in Asia Minor or the Greek campaign of the Turkish War of Independence or the Asia Minor Catastrophe, was a series of military events occurring during the partitioning of the Ottoman Empire after World War I between May 1919 and October 1922. The war was fought between Greece and Turkish revolutionaries of the Turkish National Movement that would later establish the Republic of Turkey.

The Greek campaign was launched because the western Allies, particularly British Prime Minister David Lloyd George, had promised Greece territorial gains at the expense of the Ottoman Empire. It ended with Greece giving up all territory gained during the war, returning to its pre-war borders, and engaging in a population exchange with the newly established state of Turkey under provisions in the Treaty of Lausanne.

The collective failure of the separate military campaigns of Greece, the Armenians, and the French against the Turkish revolutionaries forced the Allies to abandon the Treaty of Sèvres. Instead, they negotiated a new treaty at Lausanne. This new treaty recognised the independence of the Turkish Republic and its sovereignty over Eastern Thrace and Anatolia. [Wikipedia, 20.8.2010]
