Antipater

Antipater, who lived from about 400 BC to 319 BC, was a Macedonian general, regent and statesman who served under Philip II of Macedon and then under Philip's son Alexander the Great. He was one of Philip's foremost companions, helped Alexander secure the throne, and stayed behind as regent to hold Macedon and Greece when Alexander invaded the Persian Empire in 336 BC, crushing revolts such as that of Agis III of Sparta. After Alexander's death in 323 BC he was confirmed as viceroy of Europe. In the Lamian War he was defeated and besieged at Lamia, escaped with the help of Leonnatus, and with Craterus finally defeated the Greeks at the Battle of Crannon. He later joined Ptolemy and Antigonus against Perdiccas and was elected regent of Alexander's empire, and his son Cassander eventually ruled Macedonia as king.
