Reader's Guide
The Seleucid Empire was a major center of Hellenistic culture, where Greek customs and language were privileged, while local traditions were generally tolerated. An urban Greek elite formed the dominant political class, reinforced by steady immigration from Greece. The empire's western territories were repeatedly contested with Ptolemaic Egypt, a rival Hellenistic state. In the early second century BC, Antiochus III the Great attempted to project power into Greece but was thwarted by the Roman Republic, leading to costly war reparations and loss of territory west of the Taurus Mountains. Mithridates I of Parthia later conquered much of the eastern lands, and the empire was reduced to a rump state in Syria after a civil war, until its conquest by Tigranes the Great of Armenia in 83 BC and final overthrow by Pompey in 63 BC.
