Titus Quinctius Flamininus
In 202 BC, Rome defeated Carthage, and was free to turn her attention eastwards, urged on by her Greek allies, Rhodes and Pergamum. In 198 BC, the Second Macedonian War broke out for obscure reasons, but very likely because Rome saw Macedon as a potential ally of the Seleucids, the greatest power in the east. Philip's allies in Greece deserted him and in 197 BC he was decisively defeated at the Cynoscephalae by the Roman proconsul Titus Quinctius Flamininus.
