He was the last king of Macedonia.
After the victory at Pydna, the sympathy shown in Greece for the conquered monarch made the Romans more watchful of her interests there.
All suspected to be enemies were removed as hostages to Italy, and among these was the historian POLYBIUS.

He lived in Rome for more than twenty years, and became a great friend of the younger Africanus, whom he accompanied to the siege of Carthage.
Like Macedonia, Greece was separated into parts, independent of each other, with no rights of _connubium_ or _commercium_.

Utter demoralization soon ensued, which proved a sure preventive to all alliances liable to shake the authority of Rome.
Trouble again arose in Macedonia twenty years after Pydna, culminating in what is sometimes called the FOURTH MACEDONIAN WAR (149-146).

Under the leadership of ANDRISCUS, who claimed to be a son of Perseus, the people rebelled against the protection of Rome.

They were twice defeated in 148 by the praetor QUINTUS CAECILIUS METELLUS, who gained the agnomen of MACEDONICUS.
