Bahram I died in September 274 and was succeeded by his son Bahram II. Another son of Bahram I, Hormizd I Kushanshah, ruled over the Kushano-Sasanian kingdom in the east, and would later lead a rebellion against Bahram II, which failed. The line of Bahram I continued to rule the Sasanian Empire until 293, when Narseh overthrew the latter's grandson Bahram III and proclaimed himself the new shah. The line was thus shifted to Narseh and his descendants, who continued to rule the empire until its fall in 651.
