Antiochus III the Great (/ænˈtaɪəkəs/; Greek: Ἀντίoχoς ΜέγαςAntiochos Megas; c. 196 bc – 3 July 187 BC)[1] was a GreekHellenistic king. He was the 6th ruler of the Seleucid Empire. Antiochus ruled from 222 to 187 BC.[2][3][4] He ruled over the region of Syria and large parts of the rest of western Asia at the end of the 3rd century BC. Antiochus took the throne at the age of eighteen in 222 BC. His early campaigns against the Ptolemaic Kingdom were not successful. In the following years, Antiochus gained several military victories. The empire expanded greatly under his rule. He assumed the title Basileus Megas (Greek for "Great King"). It was the traditional title of the Persian kings. Antiochus was a militarily active ruler. He restored much of the territory of the Seleucid Empire. This ended near the end of his rule with his war against Rome.
Shortly after his defeat against the Romans, Antiochus the Great invaded Persia and pillaged a temple. He was killed while doing that. His son Seleucus IV Philopator became the next king.

Greek king who ruled an empire including Syria and western Asia (including Mesopotamia and Iran) towards the end of the 3rd century BC. It was during his time that Bactria became independent under Euthydemos. Shortly afterwards Antiochus III crossed the Hindu Kush and attacked an Indian prince named Subhagasena (Sophagasenas of the classical writers) who ruled over the Kabul valley. Antiochus III defeated Subhagasena, extorted from him a large cash indemnity and many elephants before he went back to his country. This invasion produced no permanent effect.
