Spring - Cassander secures his control of both Athens, where he installs Demetrius of Phaleron as his governor, and of Macedon itself, where he is recognized as regent of King Philip III. He secures an alliance with the King's wife Eurydice, but the former regent, Polyperchon, flees to Epirus with Alexander the Great's son, Alexander IV and his widow, Roxane. There Polyperchon makes an alliance with Alexander's mother, Olympias.
