In 308 BC the city of Athens revolted against its Macedonian garrison. The leaders of Athens, among them Agathocles and Thucydides, had planned the revolt together with Kratesipolis, the Queen of Corinth. Shortly afterwards, Cassander marched out from Pella with his army to defeat the greeks in battle and take back the city of Athens. Cassander's march was timed with Antigonus, who reigned over Asia Minor. The plan was for Antigonus to attack the southern greek cities by sea while Cassander attacked by land. Between them, they would carve up the independent greek city states.
