Founded by Seleucus I Nicator after the breakup of Alexander's empire, the Seleucid Empire was the largest Hellenistic state, controlling the Iranian plateau and Levant before shrinking under Parthian and Roman pressure.

Progressively dismembered and finally extinguished in 63 BCE when the Roman general Pompey annexed the Syrian rump state as the province of Syria.
