This chapter discusses the crises Alexander faced leading up to his succession to his father, Philip II: his dispute with Attalus at Philip’s wedding to Cleopatra, its causes, significance and aftermath; and the Pixodarus affair. It then turns to the crisis of the succession itself: the circumstances of Philip’s assassination at the hands of Pausanias, Alexander’s movements at the time of it, and the steps by which he secured the throne himself and legitimated himself as Philip’s successor.
