Amyntas was a son of King
Perdiccas III of Macedon. He was born in about 365 BC. After his father's death in 359 BC he became king, but he was only a child. His uncle,
Philip II of Macedon, who was Perdiccas' brother, became his tutor and
regent. In that same year, Philip declared himself king of Macedonia, expropriating his young nephew. Amyntas was not judged as dangerous enough to be a menace to Philip, who even gave him his daughter
Cynane in marriage. The succession of Amyntas' cousin
Alexander in 336 BC changed things — Alexander immediately had Amyntas executed.
Eurydice II of Macedon was Amyntas' daughter. ==References==
