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.
Fridtjof Nansen
After the Greco-Turkish War of 1919–1922, Nansen travelled to Istanbul to negotiate the resettlement of hundreds of thousands of refugees, mainly ethnic Greeks who had fled from Turkey after the defeat of the Greek Army. The impoverished Greek state was unable to take them in, and so Nansen devised a scheme for a population exchange whereby half a million Turks in Greece were returned to Turkey, with full financial compensation, while further loans facilitated the absorption of the refugee Greeks into their homeland. Despite some controversy over the principle of a population exchange, the plan was implemented successfully over a period of several years.
