Changes

At independence, Greece had an area of 47,515 square kilometers (18,346 square mi.), and its northern boundary extended from the Gulf of Volos to the Gulf of Arta. Under the influence of the "Megali Idea," the expansion of the Greek state to include all areas of Greek population, Greece acquired the Ionian islands in 1864; Thessaly and part of Epirus in 1881; Macedonia, Crete, Epirus, and the Aegean islands in 1913; Western Thrace in 1918; and the Dodecanese islands in 1947.

Greece entered World War I in 1917 on the side of the Allies. After the war, Greece took part in the Allied occupation of Turkey, where many Greeks still lived. In 1921, the Greek army marched toward Ankara, but was defeated by Turkish forces led by Ataturk and forced to withdraw. In a forced exchange of populations, more than 1.3 million refugees from Turkey poured into Greece, creating enormous challenges for the Greek economy and society. <ref> The unification of Greece, 1770-1923, by Douglas Dakin.</ref>
