The Illyro-Roman Wars were a series of wars fought between the Roman Republic and the Illyrian kingdom under the Ardiaei and Labeatae. In the First Illyrian War, which lasted from 229 BC to 228 BC,[1] Rome's concern was that the trade across the Adriatic Sea increased after the First Punic War at a time when Ardiaei power increased under queen Teuta.[2] Attacks on trading vessels of Rome's Italic allies by Illyrian pirates and the death of a Roman envoy named Coruncanius[3] on Teuta's orders,[4] prompted the Roman senate to dispatch a Roman army under the command of the consulsLucius Postumius Albinus and Gnaeus Fulvius Centumalus. Rome expelled Illyrian garrisons from a number of Greek cities including Epidamnus, Apollonia, Corcyra, Pharos and established a protectorate over these Greek towns. The Romans also set up[5]Demetrius of Pharos as a power in Illyria to counterbalance the power of Teuta.[6]
The Second Illyrian War lasted from 220 BC to 219 BC. In 219 BC, the Roman Republic was at war with the Celts of Cisalpine Gaul, and the Second Punic War with Carthage[7] was beginning. These distractions gave Demetrius the time he needed to build a new Illyrian war fleet. Leading this fleet of 90 ships, Demetrius sailed south of Lissus, violating his earlier treaty and starting the war.[8] Demetrius' fleet first attacked Pylos, where he captured 50 ships after several attempts. From Pylos, the fleet sailed to the Cyclades, quelling any resistance that they found on the way. Demetrius foolishly sent a fleet across the Adriatic, and, with the Illyrian forces divided, the fortified[9] city of Dimale[10] was captured by the Roman fleet under Lucius Aemilius Paulus.[11] From Dimale the navy went towards Pharos.[12] The forces of Rome routed the Illyrians and Demetrius fled to Macedon, where he became a trusted councillor at the court of Philip V of Macedon, and remained there until his death at Messene in 214 BC.[13]
In 171 BC, the Illyrian king Gentius of the Labeatae was allied with the Romans against the Macedonians. But in 169 BC he changed sides and allied himself with Perseus of Macedon. During the Third Illyrian War, in 168 BC, he arrested two Roman legati and destroyed the cities of Apollonia and Dyrrhachium, which were allied to Rome. He was defeated at Scodra by a Roman force under L. Anicius Gallus,[14] and in 167 BC he was brought to Rome as a captive to participate in Gallus' triumph, after which he was interned at Iguvium.
