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.
Convention of Constantinople (1881)
Greece had remained neutral during the Russo-Turkish War of 1877–78, based on assurances by the other Great Powers that her territorial claims on the Ottoman Empire would be considered after the war. At the Congress of Berlin in 1878, Greece's claims were considered in the Thirteenth Protocol of 5 July 1878, whereby Greece gained not only Thessaly (the Ottoman Sanjak of Tirhala) but also much of Epirus. The Ottoman government, however, refused to implement the protocol's terms, leading Greece and the Empire to the verge of war. In the end, the Great Powers applied pressure on Greece to reduce her claims.
