How a sudden internal revolt saved Epirus from total Illyrian domination in 230 BC
In 230 BC, the Illyrian Kingdom crushed the Epirote League at the Battle of Phoenice, leaving the most powerful city in Epirus in enemy hands. As Illyrian forces prepared to dismantle a combined Greek relief army, a desperate domestic uprising forced them to abandon their conquest and retreat home.
The conflict began when Illyrian forces, acting under Queen Teuta, seized Phoenice after a Gaulish garrison of 800 men surrendered. The Epirotes attempted to reclaim the city, but their strategy faltered when 5,000 Illyrian troops under Scerdilaidas advanced toward Antigoneia. By splitting their army to defend the pass, the Epirotes left their main force vulnerable. The Illyrians exploited this division, crossing the river outside Phoenice to route the Epirote army, forcing the survivors to flee to Atinania.
Following this defeat, the Epirotes sought help from the Aetolian and Achaean Leagues. A relief force gathered at Helicranum, near modern-day Ioannina, to confront the combined Illyrian armies. Despite the Hellenic alliance, the Illyrians held the tactical advantage and were poised for another victory. However, the political landscape shifted abruptly when Longarus, the ruler of the Dardanian Kingdom, invaded the Ardiaean Kingdom of Illyria. This insurrection forced Queen Teuta to recall her commanders, effectively ending the campaign in Epirus.
The withdrawal was not a total loss for the Illyrians, who departed with significant plunder and slaves. They secured a truce, returning the city of Phoenice and captured freemen in exchange for a ransom. The aftermath fundamentally altered regional alliances; disillusioned by the inability of the Greek leagues to provide effective protection, the Epirote League and Acarnania shifted their strategy, forming an alliance with their former enemy, Illyria, to counter the Achaean and Aetolian leagues.
