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 to the throne only after his death. During his reign, he was constantly involved in wars in the Eastern Mediterranean to establish Macedonian hegemony, and was ultimately defeated in the decisive battle of Qonoskfale in 197 BC. In his later years, he worked hard to consolidate the Kingdom of Macedonia, reorganized his finances, relocated his population, developed mineral resources, and issued central and local currencies. After his death, his son Perseus succeeded to the throne.

Philip V Antiochus (221 BC -179 BC) was the son of King Demetrius II of Macedonia. When his father passed away in 230 BC, he was only 9 years old. His cousin Antiochus III (the Forever Promise) was the regent of Macedonia until his death in 221 BC. In 220 BC, Philip V began his rule just as he reached adulthood.
Philip V attempted to take the initiative in the Mediterranean world at the beginning of his reign, but later he showed great clumsiness in achieving this goal. In 220 years ago, Philip V and the Achaea Alliance united against the Aetolian League, another Greek city state alliance. However, after four years of fighting, there was still no result, and the two sides finally signed a peace treaty in 217 BC. According to the treaty, the distribution of power in the Greek world remains largely 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. The Macedonian army showed great bravery in the war, helping Philip V win the battle against the superpower Rome in the Mediterranean region. Philip V successfully forced Rome to withdraw from Illyria, resulting in these areas becoming Macedonian spheres of influence.
After the death of King Ptolemy IV of Egypt (who loved his father) in 203 BC, Philip V formed an alliance with King Antiochus III of Syria (the Great) to plot to divide the territory of the young Ptolemy V. Antiochus III launched the Fifth Syrian War against Egypt (201-195 BC), while Philip V launched the Crete War. However, in 201 BC, the coalition of Antiochus III and Philip V was defeated in the Battle of Caius. Even worse, the actions of Philip V and Antiochus III caused unease in Rome, which eventually led to direct intervention by the Romans.
Philip V's massive expansion finally sparked a strong reaction from Rome. The Roman Senate decided to completely destroy the last military power on the Greek Peninsula. From 200 BC to 197 BC, Rome launched the Second Macedonian War against Macedonia. Philip V lost miserably in the Battle of Sinosephaly (the Battle of Battle of Cynoscephalae) in 197 years ago, and was forced to give up all the territory he had gained in previous victories. During the reign of Philip V's successor, Perseus, Macedonia was finally eliminated by Rome.
