The Rashīdī History 9.1.2

9.1.2

It seems probable, from what may be learned from the side of China, that the region was regarded as more or less under the power of the Moghul Khans, and the author of the Zafar-Nâma, in narrating the wars between Timur and the Moghuls, seems also to imply that this was the case, as has been seen above. Later, again, towards the middle of the fifteenth century, when a division in the Moghul Ulus had taken place, Isân Bugha II., with the support of one section, set himself up in Châlish and Turfân, and there established a separate principality, or Khanate, which lasted down to, and even beyond, the date when Mirza Haidar's history closes. Our author is fond, as will be found in the course of his narrative, of using copulate names, and therefore generally applies to this eastern Khanate, the form Châlish-Turfân, or 'Chalish and Turfan,' from its two central and principal districts. There were times, however, as he relates, when the province of Aksu also fell under the rule of the eastern Khan, though it belonged properly to Alti-Shahr. But on two occasions he mentions a country or province of Uighuristan, and in one passage, when describing the boundaries of 'Mangalai Suyah,' says that it marched, on the east, with the province of Uighuristan. It would appear, therefore, that the small eastern Khanate really bore that name down to the sixteenth century; and if this is the case, the survival is an interesting one.
