AMYNTAS I., king of Macedonia (c. 540-498 B.C.), was a
tributary vassal of [Darius Hystaspes]
? of Persia. With him the history of
Macedonia may be said to begin. He was the first of its rulers to have relations with other countries; he entered into an alliance with the Peisistratidae of
Athens, and when Hippias
? was driven out of Athens he offered him the territory of Anthemus on the Thermaic Gulf, with the object of turning the
Greek party feuds to his own advantage
