Antiochus III The Great

Antiochus III the Great (Ancient Greek: Ἀντίoχoς Μέγας; c. 241 – 187 BC, ruled 222 – 187 BC) was a Seleucid Greek king and the 6th ruler of the Seleucid Empire. He ruled over Greater Syria and western Asia towards the end of the 3rd century BCE. Rising to the throne at the age of eighteen in 223 BC, his early campaigns against the Ptolemaic Kingdom were unsuccessful, but in the following years Antiochus gained several military victories. His traditional designation, the Great, reflects an epithet he briefly assumed. He also assumed the title "Basileus Megas" (which is Greek for "Great King"), the traditional title of the Persian kings.

Declaring himself the "champion of Greek freedom against Roman domination", Antiochus III waged a war against the Roman Republic in mainland Greece in autumn of 192 BC only to be defeated.
