The Rashīdī History 76: RULE OF MUHAMMAD HAIDAR MIRZA IN KASHGHAR.

76

After the death of Saniz Mirza, son of Amir Sayyid Ali, the government of Kashghar was given to Muhammad Haidar Mirza, son of Amir Sayyid Ali (as was related above). When he had become firmly established in that place, Dust Muhammad Khan died.
Yunus Khan, in order to satisfy the Moghul Ulus, gave up all intention of inhabiting cities and cultivated lands. Muhammad Haidar Mirza, in Kashghar, acknowledged the supremacy of the Khan, who in return treated him in a fatherly way. Muhammad Haidar Mirza reigned in peace and prosperity for twenty-four years in all: that is from the year 869 to 885 (or sixteen years) he had absolute authority; and for the remainder, partial authority only.
