Philip II of Macedon
Justin's analysis

Other historians (e.g., Justin 9.7) suggested that Alexander and/or his mother Olympias were at least privy to the intrigue, if not themselves instigators. Olympias seems to have been anything but discreet in manifesting her gratitude to Pausanias, according to Justin's report: He writes that the same night of her return from exile, she placed a crown on the assassin's corpse, and later erected a tumulus over his grave and ordered that annual sacrifices be made to the memory of Pausanias.
