Even though Arrhidaeus and Alexander were about the same age, Arrhidaeus appears never to have been a danger as an alternative choice for Alexander's succession to Philip II; nevertheless, when the Persian satrap of Caria, Pixodarus, proposed his daughter in marriage to Philip, the king declined, offering his son Arrhidaeus as husband instead, and Alexander thought it prudent to block the dynastic union (which might have produced a possible future heir to Philip's domain before Alexander himself did), resulting in considerable irritation on the part of his father (337 BC).
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).
An opportunity presented itself in 317 BC when Cassander expelled Polyperchon from Macedonia.
The reaction among the troops generated by this murder was such that the regent had to give up his opposition to the proposed match and accept the marriage. Eurydice moved deftly enough to achieve the removal of the first two designated regents, Peithon and Arrhidaeus (a namesake of her husband), but was powerless to block the aspirations of Antipater, whose position proved too powerful, and the latter was made the new regent; Philip Arrhidaeus and Eurydice were forced to follow Antipater back to Macedonia. 359 BC – 25 December, 317 BC) reigned as king of Macedonia from after 11 June 323 BC until his death.He was a son of King Philip II of Macedon by Philinna of Larissa, and thus an elder half-brother of Alexander the Great.He appears as one of the main characters in the novel Funeral Games by Mary Renault.In Renault's version, the villainous Cassander slows down his advance on Macedonia to give Olympias enough time to kill Arrhidaeus and Eurydice.
It was immediately decided that Philip Arrhidaeus would reign, but not rule: this was to be the prerogative of the new regent, Perdiccas. Head of Herakles right, wearing lion skin headdress / [BASILEWS FILIPPOU], Zeus Aëtophoros seated left; wheel and monogram in left field, monogram below throne.
