Antipater

Antipater (c. 400 BC[1] – 319 BC) was a Macedonian general and statesman under kings Philip II of Macedon and Alexander the Great, and father of King Cassander. In 320 BC, he became regent of all of Alexander the Great's Empire but died the next year; he had named an officer named Polyperchon as his successor instead of his son Cassander, and a two-year-long power struggle ensued.
