Elymais or Elamais, (Graecized form of the more ancient name, Elam.) were a people who were subject to Parthian control from 247 BC to 221 AD(here to corresond to the dates of Parthia), and was the name of the region they inhabited (roughly corresponding to the region named Susiana). It was reportedly these people were great archers and natives of Susa, which lies to the east of Elymais territory. Most of the Elymais were probably descendants of the ancient Elamites, who once had control of that area in the past. Nothing is known of their language, even though "Elamite" was still used by the Achaemenid Empire 250 years before the Elymais came into existence. The kingdom of Elymais survived until its extinction by Sassanid invasion in early third century AD.
