302 BCE
Antigonus' son Demetrius Poliorcetes attacks Cassander's forces in Thessaly. Cassander loses his possessions south of Thessaly to Demetrius. Antigonus and Demetrius crown their success by renewing the pan-Hellenic league. Ambassadors from all the Hellenic states (with the exception of Sparta, Messenia and Thessaly) meet at Corinth to elect Antigonus and Demetrius protectors of the new league. Docimus, the regent of Phrygia, and Phoenix, the strategos of Lycia, desert Antigonus. The Macedonian general, Philetaerus, moves his allegiance from Antigonus to Antigonus' rival, Lysimachus. In return, Lysimachus makes Philetaerus guardian of the fortress of Pergamum with its treasure of some 9,000 talents.
