It soon became clear that Philip was too dangerous to be left alive, as Olympias' many enemies saw him as a useful tool against her, and so on 25 December 317 BC, she had him executed, while his wife was forced to commit suicide.

Manolis Andronikos, the chief archaeologist at the site, along with a number of other archaeologists, decided it was the skeleton of Philip II, but others have disputed this attribution and instead proposed it to be the remains of Philip Arrhidaeus.
He appears as one of the main characters in the novel Funeral Games by Mary Renault.
Arrhidaeus' whereabouts during the reign of his brother Alexander are unclear from the extant sources; what is certain is that no civil or military command was given to him in those thirteen years (336–323 BC).
He was in Babylon at the time of Alexander's death on 10 June 323 BC. Arrhidaeus was the most obvious candidate, but he was mentally unfit to rule.
He was a son of King Philip II of Macedon by Philinna of Larissa, and thus an elder half-brother of Alexander the Great.
Named Arrhidaeus at birth, he assumed the name Philip when he ascended to the throne.
In the Japanese fiction manga Historie, he was shown as an intellectually disabled young child that became happy when Eumenes made him a toy chariot and became sad when Alexander the Great destroyed his toy.
Eumenes later replaced it with a new one, telling him to bury the chariot.
