Andragoras

Andragoras (died c. 238 bc) was a Seleucid satrap (governor) of Parthia during the mid-3rd century. He apparently defied Seleucid imperial authority, which was weakly established in his area, and issued coins on which his image bore the royal diadem. After ruling only a few years, he was defeated and killed by Parni tribesmen from the Caspian steppes led by Arsaces, who later set up an independent kingdom in Parthia.
