Cassander (358-297 BC)
Cassander was the son of Antipater. He was a minor figure during the reign of Alexander the Great, but after the death of his father rose to be ruler and then king of Macedonia. Antipater was the regent of Macedonia during Alexander's expedition to the east. In 324 BC he had been summoned to Alexander's court at Babylon, and Craterus sent west to replace him. Rather than travel in person, Antipater sent his son Cassander. Alexander and Cassander formed an immediate dislike of each other, so severe that Cassander was suspected of having poisoned the king.
