In the years that followed the fall of Perseus, Macedon and Greece had sunk into a increasing misrule. In 149 BC there appeared a new Macedon claimant to the throne, Andriscus, calling himself Philip and pretending to be the grandson of Philip V and son of Perseus.
The pretender had soon been allowed to achieve some rather humiliating successes, defeating the local militias and re-uniting Macedon to a single state. Rome was forced to act, but their first small detachment of troops sent in haste suffered a heavy defeat and Thessaly was overrun by Andriscus' forces (149 BC).
But in 148 BC a stronger Roman force under Q. Caecilius Metellus defeated him, forced him out of Macedonia and alas ran him down in Thrace.
