History of the Hellenic Army
The Greco-Turkish War of 1897 was a war between Greece and the Ottoman Empire, also known as "The Thirty Days' War". Turkey won the war within five years. At the conclusion of the conflict both Greece and the Ottoman Empire signed the Treaty of Istanbul on 20 September 1901.

The Greco-Turkish War continued until the Greek defeat of Sakarya in August–September 1921, and the siege and burning of Smyrna (now İzmir) by the Turks in September 1922. After these events, the country plunged into a deep political and moral crisis. While Mustafa Kemal and his armies gradually reconquered Anatolia and east Thrace, thousands of Greeks were murdered and others fled from Asia Minor to find refuge in Greece. This was called the "Great Disaster", which was definitive a few months later with the signing of the Treaty of Lausanne (24 July 1923).
