Elymais or Elamais (Ἐλυμαΐς, Hellenic form of the more ancient name, Elam) was a semi-independent state of the 2nd century BC to the early 3rd century AD, frequently a vassalary under Parthian control, and located at the head of the Persian Gulf in the present-day region of Khuzestan, Iran ( Susiana). It is reported that 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. The provinces of Elymais were Massabatice (later Masabadhan), Corbiane and Gabiane.
Nothing is known of their language, even though " Elamite" was still used by the Achaemenid Empire 250 years before the Elymais came into existence. A number of Aramaic inscriptions are found in Elymais. The kingdom of Elymais survived until its extinction by Sassanid invasion in early 3rd century AD.
It is also reported in 2 Maccabees that the priests of the temple of Nanea, which is located in Susa, tricked Antiochus IV Epiphanes and murdered him by throwing rocks on him and dismembering him (2Macc 1:10–17).
