Who was the King of ancient Macedonia who conquered the other Greek states

Philip II of the ancient Greek kingdom of Macedonia. Philip unitedGreece (Hellas), under Macedonian Hegemony and together theyconquered Persia.

Quote: It is difficult to imagine thatPhilip II’s policy toward Greece was an end in itself. Once hisBalkan borders had been secured his general course seems to havebeen directed toward the establishment of stability in Greece, NOTCONQUEST.
