In 1919 the Peace Treaty with Bulgaria was signed at Neuilly, leading to the restoration of the pre-war borders -- except that Bulgaria ceded Stromnitsa to Serbia and western Thrace to Greece.
In 1920 the Treaty of Sevres marked, in theory, the end of the war with Turkey: Greece acquired sovereignty over eastern Thrace and the control of a zone around Smyrna on the coast of Asia Minor. However, this "Greater Greece" proved short-lived, and by 1923 the situation had completely changed.
After the Asia Minor Disaster in August 1922, the loss of Smyrna and eastern Thrace, the conclusion of the Treaty of Lausanne and the population exchanges between Greece and Bulgaria and between Greece and Turkey, Greece was turned into the ethnically most homogeneous state in Eastern Europe and into a firm supporter of the status quo.
The incorporation of Greek-Macedonia played a major role in the country's new international orientation, by making it possible for Greece to achieve development within its existing borders.
