Frataraka (Aramaic: Prtkr’𐡐𐡓𐡕𐡊𐡓’, "governor", or more specifically "sub-satrapal governor") is an ancient Persian title, interpreted variously as “leader, governor, forerunner”. It is an epithet or title of a series of rulers in Persis from 3rd to mid 2nd century BC, or alternatively between 295 and 220 BC, at the time of the Seleucid Empire, prior to the Parthian conquest of West Asia and Iran. Studies of frataraka coins are important to historians of this period.
