In 215 BC, however, Philip formed an alliance with Rome's enemy Carthage, which drew Rome directly into Greek affairs for the first time. Rome promptly lured the Achaean cities away from their nominal loyalty to Philip, and formed alliances with Rhodes and Pergamum, now the strongest power in Asia Minor. The First Macedonian War broke out in 212 BC, and ended inconclusively in 205 BC, but Macedon was now marked as an enemy of Rome. Rome's ally Rhodes gained control of the Aegean islands.
