2. Son of Alexander I. of Macedonia, and brother of Perdiccas II., against whom he rebelled in conjunction with Derdas.
The rebels were aided by the Athenians, in consequence of which Perdiccas instigated Potidaea, as well as the Chalcidians and Bottiaeans, to revolt from Athens. When the Athenian generals arrived, Philip acted with them in the campaign of B. C. 432.
He seems to have diedbefore B. C. 429, in which ear we find his son Amyntas contesting the throne with Perdiccas, and aided in his attempt by Sitalces, king of the Odrysian Thracians. (Thuc. 1.57
