Polysperchon, a general of Alexander the Great, died about 300 B. C. He distinguished himself in the Persian and Indian campaigns, but, not being in Babylon at the time of Alexander's death in 323, was disregarded in the distribution of power which ensued. He then attached himself to Antipater, and so gained his esteem that, passing over his own son Cassander, the regent appointed him his successor (319). He had at once to contend both against Cassander and Antigonus. He allied himself with Olympias, the mother of Alexander, sought to gain over the Greek cities by abolishing their oligarchical governments, surrendered Phocion to his enemies, and invaded the Peloponnesus. The valor of the Megalo-politans, however, forced him to retreat. At the same time he lost Macedonia, but recovered it with the assistance of Olympias (317). He was soon expelled by Cassander, and played an inglorious part in that general's struggle with Antigonus, joining first one side and then the other. In 310 he attempted to restore his fortunes by reviving the claims of Hercules, the last surviving son of Alexander, but soon sacrificed him to Cassander. Polysperchon is last mentioned in 303.
