Roman–Seleucid war in the context of "Antiochus III"

Philip V (Greek: Φίλιππος, romanized: Philippos; 238–179 BC) was king of the ancient Greek kingdom of Macedon from 221 to 179 BC. Philip's reign was principally marked by the Social War in Greece (220-217 BC) and a struggle with the emerging power of the Roman Republic. He would lead Macedon against Rome in the First (212-205 BC) and Second (200-196 BC) Macedonian Wars. While he lost the latter, Philip later allied with Rome against Antiochus III in the Roman-Seleucid War. He died in 179 BC from illness after efforts to recover the military and economic condition of Macedonia and passed the throne onto his elder son, Perseus of Macedon.

Antiochus III the Great (/ænˈtaɪəkəs/; Ancient Greek: Ἀντίοχος ὁ Μέγας, Antíokhos ho Mégas; c. 241 – 3 July 187 BC) was the sixth ruler of the Seleucid Empire, reigning from 223 to 187 BC. He ruled over the region of Syria and large parts of the rest of West Asia towards the end of the 3rd century BC. Rising to the throne at the age of eighteen in April/June 223 BC, his early campaigns against the Ptolemaic Kingdom were unsuccessful, but in the following years Antiochus gained several military victories and substantially expanded the empire's territory. His traditional designation, the Great, reflects an epithet he assumed. He also assumed the title Basileus Megas (Greek for 'Great King'), the traditional title of the Persian kings. A militarily active ruler, Antiochus restored much of the territory of the Seleucid Empire, before suffering a serious setback, towards the end of his reign, in his war against the Roman Republic. Declaring himself the "champion of Greek freedom against Roman domination", he waged a four-year war against Rome beginning in mainland Greece in the autumn of 192 BC before being decisively defeated at the Battle of Magnesia. He died three years later on campaign in the east.
