AMYNTAS I., king of Macedonia (c. B.C.), was a tributary vassal of Darius 'Hystaspes and the first Macedonian ruler to have relations with other countries. He made an alli ance with the Peisistratidae, and when Hippias was driven out of Athens he offered him the territory of Anthemus on the Ther maic gulf, hoping to turn the Greek party feuds to his own advantage (Herodotus v. 94; Justin vii. 2; Thucydides ii. I00; Pausanias ix. 40). (See MACEDONIAN EMPIRE.)
