The king of Macedonia (221 BC to 179 BC). The son of Demetrius II. In 229 BC, when his father died at a young age, he was adopted by his successor, Antiochus Dosson (Antiochus III), and ascended the throne after the death of Antiochus Dosson. During his reign, he was involved in the wars in the Eastern Mediterranean for a long time in order to establish Macedonian hegemony, and was finally defeated in the decisive battle of Kunoskefale in 197 BC. In his later years, he worked hard to consolidate the Kingdom of Macedonia, reorganize finance, migrate population, develop mineral resources, and issue central and local currency. After his death, his son Perseus succeeded him.

Philip V Antioch (221 BC - 179 BC) was the son of Demetrius II, the king of Macedonia. When his father died 230 BC, he was only 9 years old. His cousin Antiochus III (the man who promised forever) was the regent of Macedonia until his death 221 years ago. In 220 years ago, Philip V just came of age and began his rule.
Philip V tried to take the initiative in the Mediterranean world at the beginning of his accession to the throne, but later he was very clumsy in achieving this goal. In 220 years ago, Philip V and the Achaean League united against the Etolean League, another Greek city state alliance. However, after the war lasted for four years, it was still fruitless, and the two sides finally signed a peace treaty in the previous 217 years. According to the peace treaty, the distribution of power in the Greek world remained basically unchanged. Philip V made little profit in this war.
From 215 BC to 205 BC, Philip V fought with Rome with great determination, which triggered the so-called First Macedonian War. Macedonian troops showed great bravery in the war. They helped Philip V win the battle against Rome, the superpower in the Mediterranean region. Philip V successfully forced Rome to withdraw from Illyria. As a result, these regions became Macedonian spheres of influence.
After the death of Ptolemy IV, the king of Egypt (a man who loved his father), in 203 BC, Philip V and Antiochus III, the king of Syria (the Great Emperor) made an alliance to try to carve up the territory of Ptolemy V, the young king. Antiochus III then launched the fifth Syrian War (201-195 BC) against Egypt, and Philip V launched the Crete War. However, in the first 201 years, the allied forces of Antiochus III and Philip V were defeated in the Battle of Caius. Even worse, the actions of Philip V and Antiochus III caused anxiety in Rome, and finally led to the direct involvement of the Romans.
Philip V's massive expansion finally attracted a strong reaction from Rome. The Roman Senate decided to completely destroy the last military power on the Greek peninsula. From 200 to 197 years ago, Rome launched the Second Macedonian War against Macedonia. Philip V was defeated in the Battle of Cinnosephari (Battle of Kunoskephale) in 197 years ago, and was forced to give up all the territory he had gained in previous victories. During the reign of Perseus, the successor of Philip V, Macedonia was finally eliminated by Rome.
