The Rashīdī History 3.2.4

3.2.4

For the earlier periods it deals with, it is based on the traditions handed down to the author chiefly by his older relatives, combined with the statements of Sharaf-ud-Din, Yazdi in the prolegomena of the Zafar-Nama; and, for the later periods, on his personal recollections. It contains a record of two distinct and parallel dynasties: (1) that of the Khans of Moghulistan, beginning with Tughluk Timur, who reigned from 1347 to 1362, and whose father, Isan Bugha, was the first to separate from the main Chaghatai stem; and (2) of their vassals, the Dughlat Amirs of Eastern Turkistan, one of the earliest of whom, Amir Bulaji, the author's ancestor, had raised Tughluk Timur to the Khanship. In the second period, the family of the Khans divided into two branches, one of which, superseding the Amirs of Kashghar (or Eastern Turkistan), continued to rule over Moghulistan proper and Eastern Turkistan, with their capital at Kashghar, while the other became rulers of the provinces eastward of Aksu (known as Uighuristan), and had their seat of government usually at Turfan. The author concludes his account of each with a short sketch of their reigning representatives, at the time of writing.
