Narseh (also spelled Narses or Narseus; Middle Persian: 𐭭𐭥𐭮𐭧𐭩‎, New Persian: نرسه, Narsē) was the seventh Sasanian King of Kings of Iran from 293 to 303. The youngest son of Shapur I (r. 240–270), Narseh served as the governor of Sakastan, Hind and Turan under his father. Shapur I was eventually succeeded by his son Hormizd I (r. 270–271), who died after a reign of one year. Shapur I's eldest son Bahram I, who had never been considered as a candidate for succession to the throne by his father, ascended the throne with the aid of the powerful Zoroastrian priest Kartir. He then made a settlement with Narseh to give up his entitlement to the throne in return for the governorship of the important frontier province of Armenia, which was a persistent cause for war between the Roman and Sasa
