Cassander in Harpers Dictionary of Classical Antiquities（Κάσσανδρος). The son of Alexander's general, Antipater. His father, on his death-bed (B.C. 319), appointed Polysperchon regent, and conferred upon Cassander only the secondary dignity of chiliarch. Being dissatisfied with this arrangement, Cassander strengthened himself in various ways that he might carry on war with Polysperchon. First, he formed an alliance with Ptolemy and Antigonus, and next defeated Olympias and put her to death. Afterwards he joined Seleucus, Ptolemy, and Lysimachus in their war against Antigonus. This war was, on the whole, unfavourable to Cassander. In 306, Cassander took the title of king, when it was assumed by Antigonus, Lysimachus, and Ptolemy. But it was not until the year 301 that the decisive battle of Ipsus secured Cassander the possession of Macedonia and Greece. Cassander died of dropsy in 297, and was succeeded by his son Philip.
