 However, Philip was murdered by Pausanias, a member of Philip's "somatophylakes", his personal bodyguard, while attending the wedding, and Olympias, who returned to Macedonia, was suspected of having countenanced his assassination.After the death of Philip II, Olympias allegedly ordered the execution of Eurydice and her child in order to secure Alexander's position as king of Macedonia.During Alexander's campaigns, she regularly corresponded with him and may have confirmed her son's claim in Egypt that his father was not Philip but Zeus.
