Macedonian Wars
The Aeacid dynasty ended in 232 BC, but Epirus remained a substantial power, unified under the auspices of the Epirote League as a federal state with its own parliament, or "synedrion". However, it was faced with the growing threat of the expansionist Roman Republic, which fought a series of wars against Macedon. The League steered an uneasy neutral course in the first two Macedonian Wars but split in the Third Macedonian War (171–168 BC), with the Molossians siding with the Macedonians and the Chaonians and Thesprotians siding with Rome. The outcome was disastrous for Epirus; Molossia fell to Rome in 167 BC and 150,000 of its inhabitants were enslaved.
