'Ujayf ibn 'Anbasa

Ujayf ibn Anbasa (died 838) was one of the senior-most military leaders of the Abbasid Caliphate under the caliphs al-Ma'mun and al-Mu'tasim.

Biography Nothing is known of his family, but he was probably of native Khurasani or Transoxianan origin. He appears in the early 9th century as a follower of the rebel governor Rafi ibn al-Layth, but quickly abandoned him along with most of the people of Fergana and Tashkent when Caliph Harun al-Rashid himself campaigned to Khurasan in 808. Ujayf probably belonged to the same social group as the other eastern Iranian generals who were later employed by al-Mu'tasim in his "Turkish" guard, and who were minor princes or drawn from the landed gentry .

Under al-Ma'mun (r. 813–833), Ujayf became a distinguished general, campaigning in northern Persia and suppressing the Kharijite revolt of Bilal al-Dibabi in 829. and he was granted the revenue from the market of the town of Ishtikhan (near Samarkand) as a reward.
