Khosrau I

Khosrau I (also called Chosroes I in classical sources, most commonly known in Persian as Anushirvan or Anushirwan, Persian: انوشيروان meaning the immortal soul), also known as Anushiravan the Just or Anushirawan the Just (انوشیروان عادل, Anushiravān-e-ādel or انوشيروان دادگر, Anushiravān-e-dādgar) (r. 531–579), was the favourite son and successor of Kavadh I (488–531), twentieth Sassanid Emperor (Persian: Shahanshah, Great King) of Persia, and the most famous and celebrated of the Sassanid Emperors.

He laid the foundations of many cities and opulent palaces, and oversaw the repair of trade roads as well as the building of numerous bridges and dams. During Khosrau I's ambitious reign, art and science flourished in Persia and the Sassanid Empire reached its peak of glory and prosperity. His rule was preceded by his father's and succeeded by Hormizd IV. "Khosrau of the immortal soul" is one of the most popular emperors in Iranian culture and literature and, outside of Iran, his name became, like that of Caesar in the history of Rome, a designation of the Sasanian kings.
