Event #5324: Third Macedonian War between Rome and King Perseus of Macedon

The Third Macedonian War (171–168 BC) was a war fought between Rome and King Perseus of Macedon. In 179 BC King Philip V of Macedon died and his talented and ambitious son, Perseus, took his throne. Perseus married Laodike, daughter of King Seleucus IV Keraunos of Asia, and increased the size of his army. He also made alliance treaties with Epirus and several tribes of Illyria and Thrace, as well as enemies of Thracian tribes allied to Rome, such as the Sapaei under Abrupolis. He renewed former connections with some southern Greek city-states (poleis). The king announced that he could carry out reforms in Greece and restore its previous strength and prosperity.

King Eumenes II of Pergamon, who hated Macedonia, accused Perseus of trying to violate laws of other states and conditions of peace between Macedonia and Rome. The Romans were afraid for the balance of power in Greece and declared a new war with Macedonia. Perseus won the first struggle: the Battle of Callicinus, where he faced the army of Publius Licinius Crassus. The king offered a peace treaty to the Romans, which was refused. The Romans had problems with discipline in their army, and Roman commanders could not find a way to successfully invade Macedonia.

There was a stalemate near Phalanna involving Perseus and Crassus. In 169 BC, consul Quintus Marcius Philippus crossed the Olympus Range and entered Macedonia. However, his army ran out of provisions and retired on a narrow strip of coast near Tempe. Perseus tried to win Eumenes of Pergamon and King Antiochus IV of the Seleucid Empire over to his side but failed. He did, however, succeed in buying the support of the Illyrian king Genthius in the autumn of 169 BC. Perseus was defeated by the legions of the Roman consul Lucius Aemilius Paullus at the Battle of Pydna in 168 BC. This defeat was largely due to the inflexibility of Macedonian phalanx tactics compared to the maniple-based tactics of the Roman legions.

In the aftermath of this battle, King Perseus surrendered and was taken to Rome along with members of his court and other prisoners from the leading families of Macedon, including the historian Polybius. In addition, around 300,000 Macedonian citizens were enslaved. A number of Macedonian cities and villages were destroyed and their land distributed to the Roman veterans and their Thracian allies. Macedonia itself was divided into four Roman client republics, each of which was required to pay duty to Rome at half the rate previously due to the Macedonian kings. Economic and political contacts between the four republics were restricted. The Third Macedonian war marked the end of the Macedon kingdom and the monarchy of the Antigonid dynasty, and the beginning of the end of the overall Hellenistic world. It further enhanced Roman domination of Ancient Greece, and Rome later returned to symbolically destroy Corinth in 146 BC in their war with Achaea, in a manner reminiscent of their destruction of the defanged Carthage in the Third Punic War.

Perseus (c. 212 – 166 BC) was the last king (Basileus) of the Antigonid dynasty, who ruled the successor state in Macedon created upon the death of Alexander the Great. 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.

Perseus was the son of king Philip V of Macedon and a concubine, probably Polycratia of Argos. He therefore feared that the throne might pass on his legitimate younger brother Demetrius, not least due to interference from the Romans, who considered their former hostage Demetrius a true friend. Perseus thus staged a plot to make their father believe that his brother was a traitor, and as a result Philip had Demetrius executed.

In 179 BC Philip V of Macedon died and Perseus took the throne. Although his role in killing Demetrius had not endeared him to the Romans, one of his first acts on becoming king was to renew the treaty with the Republic. Yet, Perseus’ other actions troubled the Senate. His interference in the affairs of his neighbors, his ousting of the Roman ally Abrupolis from his territories in Thrace, his armed visit to Delphi, his avoidance of the Roman ambassadors to Macedonia, and his dynastic marriages all gave the Romans cause for concern.

Soon Rome and Perseus went to war in the Third Macedonian War (171-168 BC). Although Perseus had some initial success, the war ended with the King’s surrender to the Roman general Lucius Aemilius Paullus after his decisive defeat at the Battle of Pydna, and his eventual imprisonment in Rome with his half-brother Philippus and son Alexander. Blaise Pascal mentions in his Pensées (Lafuma 15) that Perseus was blamed for not committing suicide, supposedly after his defeat at Pydna. The Antigonid kingdom was dissolved, and replaced with four republics. Andriscus of Macedon broke off the Roman rule for about a year, but was defeated in 148 BC by the Romans. In 146 BC, following the quashing of a rebellion led by the last Macedonian king Andriscus, the four republics were dissolved, and Macedon officially became the Roman province of Macedonia.

In 178 BC, he had married Laodice V, the daughter of Seleucus IV from Syria. One son of Perseus and Laodice, Alexander was still a child when Perseus was conquered by the Romans, and after the triumph of Aemilius Paullus in 167 BC, was kept in custody at Alba Fucens, together with his father. He became a skillful metalworker, learned the Latin language, and became a public notary.
