Antipater

Antipater was appointed regent of Macedon and Greece by Alexander the Great when Alexander left for his Asian campaign. He governed effectively, suppressing revolts in Thrace and Greece, and maintained stability in the Macedonian homeland for over a decade.

Antipater led Macedonian forces to crush a Spartan-led revolt in Greece. He defeated King Agis III at the Battle of Megalopolis, ending the last serious challenge to Macedonian control in Greece during Alexander's reign.

After Alexander's death, Antipater faced a coalition of Greek states led by Athens and Aetolia in the Lamian War. He was initially besieged in Lamia but later relieved by reinforcements. He defeated the Greeks at the Battle of Crannon in 322 BC, reimposing Macedonian hegemony.

At the Partition of Babylon after Alexander's death, Antipater was confirmed as regent of Macedon and Greece, while other generals received satrapies. This agreement established the framework for the Wars of the Diadochi.
