Treaty for the Foundation of the League of Cities and Federal States Promoted by Antigonus and Demetrius
This inscription, found in Epidaurus, preserves a treaty for the foundation of a league of poleis and ethne promoted by Antigonus Monophthalmus and Demetrius Poliorcetes. The league formally was a symmachia and its administrative body included a synedrion, i.e. an assembly of league members, five proedri, and a strategos representing Antigonus and Demetrius. It is impossible to list all the members of this league, but it is known that the coalition included Epidaurus, Achaia and Aelis, and possibly those areas of the Peloponnese which Demetrius freed in 303 BC, and Athens. Antigonus and Demetrius organised the league to gather a force against Cassander and to establish their hegemony over Greece. However, the league was short-lived. It was founded in 302 BC and it ceased to exist the year after when Antigonus died at Ipsus (301 BC).
