Philip V of Macedon - Second Macedonian War

Second Macedonian War

In 200 BC, with Carthage no longer a threat, the Romans declared war on Macedon arguing that they were intervening to protect the freedom of the Greeks. After campaigns in Macedonia in 199 BC and Thessaly in 198 BC, Philip and his Macedonian forces were decisively defeated at the Battle of Cynoscephalae in 197 BC. The war also proved the superiority of the Roman legion over the Greek phalanx formation.
