Khosrow II (Khosrow Parviz) (khŏsrō´; pärvēz´), d. 628, king of Persia of the Sassanid, or Sassanian, dynasty; grandson of Khosrow I. He is also called Chosroes II or Khosru II. He succeeded his father Hormizd, or Hormoz, in 590, but he was opposed by the usurper Bahram Chubin, and forced to flee to the Byzantine Empire. Emperor Maurice aided him in overthrowing Bahram, but Khosrow had to cede practically all of Armenia. When Maurice was murdered by the tyrant Phocas, Khosrow declared a war of revenge against his murderer and conquered much Byzantine territory until he was finally defeated by Heraclius. Khosrow was murdered by his son and successor, Kavadh II Shiruya.
