Kartir was a powerful and influential Zoroastrian priest during the reigns of four Sasanian kings in the 3rd century. His name is cited in the inscriptions of Shapur I and the Paikuli inscription of Narseh. Kartir also had inscriptions of his own made in the present-day Fars Province. His inscriptions narrates his rise to power throughout the reigns of Shapur I, Hormizd I, Bahram I, and Bahram II. During the brief reign of Bahram II's son and successor Bahram III, Kartir was amongst the nobles who supported the rebellion of Narseh, who overthrew Bahram III and ascended the throne. During Narseh's reign, Kartir faded into obscurity.
