The early policy of Ambracia was determined by its loyalty to Corinth (for which it probably served as an entrepot in the Epirus trade), its consequent aversion to Corcyra, and its frontier disputes with the Amphilochians and Acarnanians.
About the same time the successes of Timotheus in the west resulted in the addition to the league of Corcyra and the cities of Cephallenia, and his moderation induced the Acarnanians and Alcetas, the Molossian king, to follow their example.
He subsequently recovered his kingdom by the aid of the Acarnanians and Aetolians.
But the most frequent votaries were the neighbouring tribes of the Acarnanians and Aetolians, together with the Boeotians, who claimed a special connexion with the district.
- Actium belonged originally to the Corinthian colonists of Anactorium, who probably founded the worship of Apollo Actius and the Actia games; in the 3rd century it fell to the Acarnanians, who subsequently held their synods there.
