Kushanshah

Kushanshah was the title used by the rulers of the parts of the former Kushan Empire. The title is first attested in the Paikuli inscription of the Sasanian shah Narseh in ca. 293, where it functioned as a title for the Sasanian governors of the eastern portion of the empire. The title was also used by the Kidarite dynasty, which was the last kingdom to make use of it.
