The Complex Mystery Of The Figure Of Shapur The First

  Pars, a region in the southwestern Iranian plateau, was the homeland of the southwestern branch of the Iranian people, the Persians. It was also the birthplace of the first Iranian Empire, the Achaemenids. The region served as the center of the empire until its conquest by the Macedonian king Alexander the Great (r. 336–323 BC). Since the end of the 3rd or the beginning of the 2nd century BC, Pars was ruled by local dynasts subject to the Hellenistic Seleucid Empire. These dynasts held the ancient Persian title of Frataraka ("leader, governor, forerunner"), which is also attested in the Achaemenid era. Later under the Frataraka Wadfradad II (fl. 138 BC) was made a vassal of the Iranian Parthian (Arsacid) Empire. The Frataraka was shortly afterward replaced by the Kings of Persis, most likely at the accession of the Arsacid monarch Phraates II, Unlike the Fratarakas, the Kings of Persis used the title of the shah ("king"), and laid the foundations for a new dynasty, which may be labeled the Darayanids
