Abu 'Ali Chaghani
Abu 'Ali Ahmad Chaghani was the most prominent of the Muhtajid rulers. He succeeded his father in his posts in 939 and earnestly fought to maintain a Samanid presence in northern Iran, attempting to stem there the rise of the Buyids, Dailamite officers who had already taken over southwest Iran. He fell out of favor with the Samanid amir Nuh b. Nasr and was removed from the governorship of Khurasan. Refusing to accept this, he revolted and installed in Bukhara another Samanid, but eventually Nuh retook Bukhara. Despite this, he was unable to defeat Abu 'Ali, and in the end he allowed him to retain his rule of Chaghaniyan. In 952 Abu 'Ali was made governor of Khurasan a second time, but only a year later was again dismissed. He fled to the Buyids and died in 955.
