reign had been at war with the Aetolian and Achaean Leagues. In response, the king brought Agron into the conflict. The Illyrian attack under Agron, mounted in either 232 or 231 BC, is described by Polybius: The defeat of the Aetolians, famed for their victory over the invading Gauls a generation before, caused a sensation in Illyria. Agron was beside himself with delight when his ships returned and he learned of the victory from his commanders. Agron then drank so much by way of celebration, it was reported, that this and other similar indulgences, brought on an attack of pleurisy which killed him within a few days. Agron died in the winter of 231 BC. The Greek cities (poleis) on the coast of Illyria were systematically attacked and perhaps already conquered by Agron's forces. Rome answered an appeal from the island of Vis (Issa), threatened by Agron, by sending envoys. They never got there. They were attacked en route by Illyrian vessels, and one of them was killed, together with an Issaean ambassador. Rome thereupon undertook military action against Agron's wife, Teuta, Agron having died in the interim. His son, Pinnes, succeeded him and ruled de jure (though never de facto) for thirteen years. Tritueta was Agron's first wife and the mother of Pinnes. Agron divorced her. Agron's second wife was Queen Teuta, who acted as regent after Agron's death.
