What did King Philip of ancient Greece do

King Philip II ruled Macedonia from 359 to 336 BC. He was born in Pella, the capital of the ancient Macedonian kingdom, as the youngest son of king Amyntas III. After his fathers death, Macedonia slowly disintegrated as his elder brothers and future kings Alexander II and Perdiccas III, unsuccessfully fought against the continuous attacks of the neighboring Thracians, Illyrians, and Greeks. The Thracians were already in possession of eastern Macedonia, the strongest Greek military power of Thebes continuously intervened in the internal Macedonian politics, the Greeks colonies on the edge of Macedonia, particularly Olynthus, were obstacle to Macedonia’s economy and presented a military danger, and the invasions of the Illyrians put north-western Macedonia under their occupation.
