Agron was king of that part of Illyria which borders
the Adriatic Sea, over which sea Pyrrhus, king of Epirus, and his successors held sway. Agron captured a part of Epirus and also Corcyra, Epidamnus, and Pharus in succession, where he established garrisons. When he threatened the rest of the Adriatic with his fleet, the isle of Issa implored the aid of the Romans. The latter sent ambassadors to accompany the Issii and to ascertain what offences Agron imputed to them. The Illyrian vessels attacked the ambassadors on their voyage and slew Cleemporus, the envoy of Issa, and the Roman Coruncanius; the remainder escaped
by flight. Thereupon the Romans invaded Illyria by land
and sea. Agron, in the meantime, had died, leaving an infant son named Pinnes, having given the guardianship and regency to his wife, although she was not the child's mother. Demetrius, who was Agron's governor of Pharus and who held Corcyra also, surrendered both places to the invading Romans by treachery. The latter then entered into an alliance with Epidamnus and went to the assistance of the Issii and of the Epidamnians, who were besieged by the Illyrians. The latter raised the siege and fled, and one of their tribes, called the Atintani, went over to the Romans. After these
events the widow of Agron sent ambassadors to Rome to
surrender the prisoners and deserters into their hands. She begged pardon also for what had been done, not by herself, but by Agron. They received for answer that Corcyra, Pharus, Issa, Epidamnus, and the Illyrian Atintani were already Roman subjects, that Pinnes might have the remainder of Agron's kingdom and be a friend of the Roman people if he would keep hands off the aforesaid territory, and agree not to sail beyond Lissus nor to keep more than two Illyrian pinnaces, both to be unarmed. The woman accepted all these conditions.
