Shahrokh Mirza, better known by his dynastic title of Shahrokh Shah was the Afsharid king (shah) of the western part of Khorasan from 1748 to 1796, with a two-month interruption. A grandson of the Iranian conqueror Nader Shah, Shahrokh was the son of Reza Qoli Mirza Afshar and his Safavid wife Fatemeh Soltan Begom, who was the sister of Tahmasp II, the penultimate Safavid shah of Iran. Shahrokh's half-Safavid descent made him stand out amongst his Afsharid relatives, and was used to bolster the legitimacy of his grandfather. After the assassination of Nader Shah in 1747, his nephew Ali-qoli Khan, ascended the throne in Mashhad and had all of Nader Shah's descendants in fortress of Kalat massacred. Shahrokh was spared in case his Safavid lineage would come to use, and was instead kept in the fortress as a prisoner. While Adel Shah was battling his rebellious younger brother Ebrahim Mirza, a party of Turkic, Kurdish, and Arab tribal leaders took advantage of his absence and installed Shahrokh on the throne. Both Adel Shah and Ebrahim were eventually defeated and killed, but Shahrokh was not long afterwards overthrown by a party of dissident tribal leaders, who installed the Safavid pretender Mir Sayyed Mohammad on the throne. Shahrokh was soon blinded at the instigation of Mir Alam Khan Khuzayma and other leading nobles, much against Suleiman II's will.
