Greco-Turkish War (1919–1922)
The Greco-Turkish War of 1919–1922 was fought between Greece and the Turkish National Movement during the partitioning of the Ottoman Empire after World War I between May 1919 and October 1922. It is known as the Western Front (, ) of the Turkish War of Independence in Turkey and the Asia Minor Campaign () or the Asia Minor Catastrophe () in Greece.
Enosis
Thessaly remained under Ottoman control after the formation of the Kingdom of Greece. Although parts of the territory had participated in the initial uprisings in the Greek War of Independence in 1821, the revolts had been swiftly crushed. During the Russo-Turkish War of 1877–78 Greece remained neutral, as a result of assurances by the Great Powers that her territorial claims on the Ottoman Empire would be considered after the war. In 1881 Greece and the Ottoman Empire signed the Convention of Constantinople which created a new Greco-Turkish border, incorporating most of Thessaly into Greece.
