Cassander

Cassander (354-297 B.C.), King of Macedonia. Being passed over in the succession by his father Antipater, he allied himself with Antigonus and Ptolemy, and after gaining most of the Greek cities, including Athens, he invaded Macedonia, and by the year 306 had made himself King. His wife was Thessalonica, the sister of Alexander, and in her honour he founded the city, which bore her name. In his later life he joined Lysimachus, Ptolemy, and Seleucus against Antigonus, who was killed at the battle of Ipsus (301), and he left his crown to his son Philip.
