Epirote League - Authority in Ἄπειρος from 370 BC to 168 BC
The Epirote League was an ancient Greek coalition, or koinon, of Epirote tribes. The coalition was established between 370 and 320 BC, which helped unify the three main tribes of Epirus. The political, economic, and cultural center of the Epirote League was the oracle of Dodona.

In 297 BC, Pyrrhus of Epirus became leader of the League. He would go on to his famous struggle against the Roman Republic, before ultimately depleting his army with costly wins - a so-called Pyrrhic victory - costing him the war.

Although the Epirote League remained neutral in the first two Macedonian Wars, it was ultimately dismantled in the Third Macedonian War (171–168 BC), with the Molossians siding with the Macedonians and the Chaonians and Thesprotians supporting the Roman Republic.
