Macedonian Wars, (3rd and 2nd centuries bc), four conflicts between the ancient Roman Republic and the kingdom of Macedonia. They caused increasing involvement by Rome in Greek affairs and helped lead to Roman domination of the entire eastern Mediterranean area.
The First Macedonian War (215–205 bc) occurred in the context of the Second Punic War, while Rome was preoccupied with fighting Carthage. The ambitious Macedonian king Philip V set out to attack Rome’s client states in neighbouring Illyria and confirmed his purpose in 215 by making an alliance with Hannibal of Carthage against Rome. The Romans fought the ensuing war ineffectively, and in 205 the Peace of Phoenice ended the conflict on terms favourable to Philip, allowing him to keep his conquests in Illyria.
Philip then began harrying Rhodes, Pergamum, and other Greek city-states of the Aegean. The Second Macedonian War (200–196) was launched by the Roman Senate against Philip after he refused to guarantee to make no hostile moves against these states. Philip’s forces were badly defeated by the Romans and their Greek allies in a battle at Cynoscephalae in 197. The terms of peace included the loss of most of his navy, payment of a large indemnity to Rome, and the loss of his territories outside of Macedonia. Rome subsequently established a benevolent protectorate over Greece.
Philip’s son and successor, Perseus (reigned 179–168), began to make alliances with various Greek city-states and thus aroused the displeasure of Rome. So began the Third Macedonian War (171–168), which ended in 168 when the Roman army of Lucius Aemilius Paullus utterly defeated Perseus’ forces at the Battle of Pydna. Perseus was taken back to Rome in chains, and Macedonia was broken up into four formally autonomous republics that were required to pay annual tribute to Rome. This arrangement produced a state of chronic disorder in Macedonia, however, and in 152 a pretended son of Perseus, Andriscus, tried to reestablish the Macedonian monarchy, thus provoking the Fourth Macedonian War (149–148). The Roman praetor Quintus Caecilius Metellus crushed the rebellion with relative ease, and in 146 Macedonia was made a Roman province. It was in fact the first province of the nascent Roman Empire.
