Alexander (son of Polyperchon)

Alexander (Greek: Αλέξανδρος; killed 314 BC) was son of Polyperchon, the regent of Macedonia, and an important general in the Wars of the Diadochi.

Antipater, on his death (319 BC), had left the regency to Polyperchon, to the exclusion and consequent discontent of his own son, Cassander. The chief men, who had been placed in authority by Antipater in the garrisoned towns of Greece, were favourable to Cassander, as their patron's son, and Polyperchon's policy, therefore, was to reverse the measures of Antipater, and restore democracy where it had been abolished by the latter. It was then, in the prosecution of this design, that his son Alexander was sent to Athens, 318 BC, with the alleged object of delivering the city from Nicanor, who by Cassander's appointment commanded the garrison placed by Antipater in Munychia. Before his arrival, Nicanor, besides strengthening himself with fresh troops in Munychia, had also treacherously seized the Piraeus. To occupy these two ports himself soon appeared to be no less the intention of Alexander, an intention which he had probably formed before any communication with Phocion, though Diodorus seems to imply the contrary. The Athenians, however, looked on Phocion as the author of the design, and their suspicions and anger being excited by the private conferences of Alexander with Nicanor, Phocion was accused of treason, and, fleeing with several of his friends to Alexander, was by him despatched to Polyperchon. Cassander, arriving at Athens soon after and occupying the Piraeus, was there besieged by Polyperchon with a large force; but the supplies of the latter being inadequate, he was obliged to withdraw a portion of his army, with which he went to attempt the reduction of Megalopolis, while Alexander was left in command of the remainder at Athens. Here he appears to have continued without effecting anything, till the treaty and capitulation of Athens with Cassander gave the city to the power of the latter.
