(Based on Η ιστορική πορεία της Μακεδονίας by A Ch Kostapoulos)
After they had broken off from other Indo-European tribes in the latter half of the third millennium before Christ, the Greeks moved to the region of Macedonia where they came to be known as πελασγοί (pelasyi). Archealogical, historical, linguistic and all other evidence clearly show that Western Macedonia was the ancient homeland of all Greeks. This was where the "Protohellenes" lived.
During the waves of migration in the first century of the second millennium BC, the Protohellenes, the Aioleans, the Achaians and other Greek tribes moved to the south. The Macedons remanded in Macedonia with all the Greek gods.
The Protohellenes enthroned their gods on the Macedonian Mount Olympus where they were hymned by Homer, Hesiod, and Theogonia.
