Seleucid dynasty
The Seleucid dynasty or the Seleucidae (; Greek: Σελευκίδαι, Seleukídai, "descendants of Seleucus") was a Macedonian Greek royal family, which ruled the Seleucid Empire based in West Asia during the Hellenistic period. It was founded by Seleucus I Nicator, a general and successor of Alexander the Great, after the division of the Macedonian Empire as a result of the Wars of the Successors (Diadochi).
