control over all of Khurasan and Transoxiana from the Persian Tahirid dynasty. He even secretly supported Mazyar, the Karenid ruler of Tabaristan, who had rebelled against the Abbasids. The rebellion, however, was soon suppressed, and Afshin's ambitions were revealed by the Abbasids. Furthermore, Afshin was accused of being a Zoroastrian, and he was soon imprisoned and died. His successor is not known; however, the Afshin family continued to rule Ushrusana until 892, when the Samanid ruler Isma'il ibn Ahmad incorporated Ushrusana into his Empire and killed its ruler, Sayyar ibn 'Abdallah.
