After the Roman victory, the balance of naval power in the Western Mediterranean had shifted from Carthage to Rome. This ensured Carthaginian acquiescence to the conquest of Sardinia and Corsica, and also enabled Rome to deal decisively with the threat posed by the Illyrian pirates in the Adriatic. The Illyrian Wars marked Rome's first involvement with the affairs of the Balkan peninsula. Initially, in 229 BC, a fleet of 200 warships was sent against Queen Teuta, and swiftly expelled the Illyrian garrisons from the Greek coastal cities of modern-day Albania. Ten years later, the Romans sent another expedition in the area against Demetrius of Pharos, who had rebuilt the Illyrian navy and engaged in piracy up into the Aegean. Demetrius was supported by Philip V of Macedon, who had grown anxious at the expansion of Roman power in Illyria. The Romans were again quickly victorious and expanded their Illyrian protectorate, but the beginning of the Second Punic War (218–201 BC) forced them to divert their resources westwards for the next decades.
