The Macedonian troops refused to fight Olympias, the mother of Alexander.
In Renault's version, the villainous Cassander slows down his advance on Macedonia to give Olympias enough time to kill Arrhidaeus and Eurydice.
Arrhidaeus is also a main character in Annabel Lyon's novel The Golden Mean.
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.
When news arrived in Macedonia that Arrhidaeus had been chosen as king, Cynane, a daughter of Philip II, developed a plan to travel to Asia and offer the new king her daughter Eurydice for wife. Eurydice's chance to increase her husband's power came when the first war of the Diadochi sealed the fate of Perdiccas, making a new settlement necessary.
This move was an obvious affront to the regent, whom Cynane had completely bypassed, and to prevent the marriage, Perdiccas sent his brother, Alcetas, to kill Cynane. An agreement was made at Triparadisus in Syria in 320 BC.
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.
Cassander's refusal to accept his father's decision sparked the Second War of the Diadochi, in which Eurydice saw once again a chance to free Philip from the control of the regent.
An opportunity presented itself in 317 BC when Cassander expelled Polyperchon from Macedonia.
This eventuality did indeed arise and resulted in Roxana's son, Alexander, becoming with his uncle Phillip III co-sovereign on the throne of Macedon.
