How was King Philip II of Macedonia murdered?

King Philip II of Macedonia was assassinated in 336 BC during a festival in Aegae, the ancient capital of Macedonia. He was killed by Pausanias of Orestis, one of his bodyguards, who reportedly harbored a personal grievance against the king. The assassination occurred as Philip was entering the theater to attend the wedding of his daughter. The motives behind the assassination are still debated, with theories ranging from personal revenge to possible political conspiracies.
