アンティオコス3世

Antiochus III was a powerful ruler of the Seleucid Empire in the eastern Mediterranean who reigned from 223 to 187 BC and earned the title "the Great" for his military conquests and efforts to expand his realm. He matters historically because his reign marked both the height of Seleucid power and the beginning of its decline, as his eventual military defeat by Rome shifted the balance of power in the ancient world.
