How a single wedding toast triggered the downfall of a powerful Macedonian general

History · Published 3 October 2026 Swipe more like this →

In short: Attalus was a prominent courtier and commander under Philip II, but his influence proved fatal. By publicly praying for a legitimate heir through his niece, he alienated Alexander the Great. This ambition, coupled with a scandalous history of personal vengeance, ultimately led to his execution during the transition of power.

Born in Lower Macedonia in 390 BC, Attalus rose to become a key figure in the court of Philip II. His political standing peaked in 338 BC when his niece, Cleopatra Eurydice, married the king. At the wedding festivities, Attalus offered a prayer that the union would produce a legitimate male heir. This gesture was interpreted as a direct affront to Alexander the Great, who viewed the comment as a challenge to his own status as the king's successor.

Beyond court politics, Attalus was entangled in a cycle of violence involving Pausanias of Orestis. According to accounts by Aristotle, Cleitarchus, and Diodorus Siculus, Attalus had sexually assaulted Pausanias of Orestis as retribution for a previous dispute. When Philip II failed to punish Attalus for this act, the humiliated Pausanias of Orestis eventually assassinated the king. This act of regicide set the stage for a brutal purge, as Alexander ascended to the throne in October 336 BC and oversaw the deaths of Cleopatra Eurydice and her children.

At the time of Philip's death, Attalus was stationed in Asia Minor as a commander of the advance force alongside Parmenion. Despite his attempts to secure his position by forwarding letters from Demosthenes of Athens to Alexander—thereby pledging his loyalty—the new king remained suspicious. Alexander likely viewed Attalus as a dangerous rival with significant influence over the army. Fearing his ambition and anticipating potential retaliation for the murder of his niece, Alexander ordered an officer to Asia Minor to eliminate him. Attalus was executed in 336 BC, marking the end of a career defined by high-stakes court intrigue and personal vendettas.
