He also has the distinction of being the last of the line, after losing the Battle of Pydna on 22 June 168 BC; subsequently Macedon came under Roman rule. - The Third Macedonian War (171168 BC) was a war fought between the Roman Republic and King Perseus of Macedon. In 179 BC King Philip V of Macedon died and was succeeded by his ambitious son Perseus. He was anti-Roman and stirred anti-Roman feelings around Macedonia. He was suspected of preparing for war against Rome by the Romans and their most important ally in the east, Eumenes II of Pergamon. Tensions escalated and Rome declared war on Macedon. The Romans marched with newly recruited and quite inexperienced troops from Epirus, on the west coast, to Thessaly through difficult mountain passes. It is likely that the priority of the Roman commander was to establish a solid foothold in Thessaly. What is the relationship between 'philippus ' and 'philip v of macedon'?
