Andriscus in Wikipedia
Andriscus, (Greek: Ἀνδρίσκος), also spelt Andriskos and often called the "pseudo-Philip", was the last King of Macedonia (149 BC - 148 BC), and ruler of Adramyttium in Aeolis (in western Anatolia).
In 168 BC, the Romans had invaded Macedonia and overthrew the king, Perseus, in the First Battle of Pydna.
In 149 BC, Andriskos, at that time ruler of Adramyttium only, and claiming to be Perseus' son, announced his intention to retake Macedonia from the Romans.
As his first attempt, Andriskos travelled to Syria to request military help from Demetrius Soter of Syria. Demetrius instead handed him over to the Romans.
Andriskos escaped from Roman captivity, and raised a Thracian army. With this army, he invaded Macedonia and successfully defeated the Roman praetor Publius Juventius in 149 BC. Andriskos then declared himself King Philip VI of Macedonia.
In 148 BC, Andriskos conquered Thessaly and made an alliance with Carthage, thus bringing the Roman wrath on him. In 148 BC, in what the Romans called the Fourth Macedonian War, he was defeated by the Roman praetor Q. Caecilius Metellus (148) at the Second Battle of Pydna, and fled to Thrace, whose prince gave him up to Rome, thus marking the final end to Andriskos' reign of Macedonia.
Andriscus's brief reign over Macedonia was marked by cruelty and extortion. After this Macedonia was formally reduced to a Roman province.
