I may also add that Tamgaj, the name of which often appears in this Section, is a territory of Turkistan, as well as a name given to rulers, and that some writers state that it is the name — dynastic name, probably — of the sovereigns of Tibbat and Yughma, which last word is also the name of an old city and territory in Turkistan. XXII. Jalal-ud-Din, ’Ali, son of Hasan-Tigin [Rashid-ud-Din calls him Husain merely], son of ’Ali, son of ’Abd-ul-Mumin, who bore the title of Khizr Khan — some say Jaghar Khan — with the support of the Gur Khan of the Kara-Khita-is, after Sultan Sanjar’s defeat at Katwan, succeeded to the sovereignty of Mawara-un-Nahr. Khizr Khan, subsequently [in 553 H.] slew, in Khita it is said, Beghu or Beghun Khan, the chief of the Karluks or Karlughs, and other chiefs of that tribe, then located in Mawara-un-Nahr, such as La-chin Beg, and, the sons of the slain Beghu, fled to the Khwarazm territory, and connecting themselves with Sultan I-yal-Arsalan, Khwarazm Shah, instigated him to attack Khizr Khan, the Khakan, as he is also styled — another title by which this dynasty is also called — of Samrkand, that is to say, Mawara-un-Nahr. This is a sufficient proof that the rulers were not Karlughs, and that they were I-ghurs is utterly out of the question. I-yal-Arsalan, Khwarazm Shah, accordingly, in the same year [553 H. — A.D. 1158], in Jamadi-ul-Akhir, marched an army into Mawara-un-Nahr, arrived at Bukhara, and, from thence, moved towards Samrkand.
