Acarnanian League

[3] The Acarnanians agreed to provide 2,000 hoplites in the common struggle against Philip II of Macedon, but as the latter occupied Ambracia, only a handful volunteers participated alongside the southern Greek city-states in the Battle of Chaeronea.

270 BCE, the Acarnanians and Aetolians settled their differences, agreeing on the Acheloos River as their mutual border, and concluded a perpetual alliance.

The treaty specified the obligations of mutual military assistance, and the two leagues assured each other the rights of epigamia, citizenship, and acquisition of property.

[5] Following the extinction of the Aeacid dynasty in Epirus, in 230 BCE the Acarnanian League was reconstituted in the northern, former Epirote part of the country.

Despite their steadfast loyalty to Rome, the League lost Leucas after the Third Macedonian War (171–168 BCE), as it became an autonomous state, but Thyrreion became a member.
