Alexander the Great

In 336BC Philip of Macedonia was murdered. The murder of Philip was surrounded by many major events. These events were some of the motives for Alexander and Olympias wanting Philip dead. We know it was not Olympias and Alexander who pierced the knife through Philip, as that was Pausanias.
However it seems more than likely that they both, or even just one, may have been whispering in his ear.

Pausanias of Orestis was Philip’s ex-lover, who was replaced by another man also called Pausanias. Pausanias of Orestis made the other Pausanias life such a living hell, that he committed suicide. The second Pausanias had confided in Attalus before he died and this left Attalus wanting vengeance.
One night Attalus got Pausanias of Orestis drunk then left him to the stable boys to do with him as they pleased.
The next day when Pausanias woke up, he realised what had happened to him and went to Philip to get revenge. Philip could not help Pausanias though and offered him a job instead...
