256.2.2

XIX. Hasan-Tigin, son of 'Ali, son of 'Abd-ul-Mumin [Alfi has, son of 'Abd-ul-Mumin, son of 'Ali], famous under the name of Abu-l-Ma'ali, Kulij-i-Tamghaj, who likewise was of the same family, was, by command of Sultan Sanjar, raised to the sovereignty, but he died very shortly after. XX. Rukn-ud-Din, Mahmud Khan, Arsalan’s son, and great nephew of Sanjar, who is mentioned in the Jami'-ut-Tawarikh and in Alfi as the rous, they began to act in a refractory manner. The Khakan, Rukn-ud-Din, Mas'ud, son of Muhammad, son of the Bughra Khan [No. X. Yafa-i says he was his great grandson], with the support of Sultan Sanjar was raised to the throne in 526 H., and, in Ramadan 531 H., he encountered the Gur Khan of the Kara Khita-i in battle, within the limits of Khujand, but was defeated, and compelled to retire to Samrkand. Sultan Sanjar advanced soon after to his assistance with his forces, but he also was overthrown [in 534 H., A.D. 1134. Guzidah and others say in 535 H. Jami'-ut-Tawarikh says in 536 H.] by the Khita-is under At Khan and Baniko, as has been already stated under Sanjar's reign, at page 154, but, since that portion of this work was translated, some further particulars, tending to throw light on this subject, will be found in the notice of the Gur Khans farther on.
