SATRAP
(Gr.: from Old Persian “xshathrapãvan”: “protector of the country”).
Official title of the viceroy appointed by the king of Persia to exercise civil and military authority over several small provinces that formed a governorate. Each of these small provinces had its own governor (Ezra 8:36; Esther 3:12).
The title of satrap appears in historical documents in Aramaic written after the Persian conquest; designates high officials of the Babylonian empire and the kingdom of Darius of Media (Dan. 3:2; 6:1).
