أنطيوخوس الثالث
In the early second century BC, Antiochus III the Great attempted to project Seleucid power and authority into Hellenistic Greece, but his attempts were thwarted by the Roman Republic and its Greek allies; the Seleucids were forced to pay costly war reparations and relinquish territorial claims west of the Taurus Mountains, marking the gradual decline of their empire.
