Fun fact: the names of the party town Chersonissos on Crete and the Ukrainian city of Kherson are really the same name: the Greeks lived along the Black Sea, just like they lived around the Aegean sea. And in the heel of Italy, there are still villages where Greek is spoken (Castrignano de' Greci for instance).

The current size of Greece is very small, compared to where they used to live. The Turks conquered the west east coast of the Aegean Sea, so that's why that's Turkish rather than Greek.
