The Rashīdī History 153: CHAPTER XL. · DESCRIPTION OF KASHGHAR.

153

Kashghar is an old and famous town. In former times the Sultans of Kashghar were of the family of Afrasiab the Turk, whom the Moghuls call Bughra Khan. His genealogy is as follows: Afrasiab, son of Pish, son of Dad Nashin, son of Tur, son of Afaridun. It is thus given in the Tarikh-i-Guzida, which has copied from the Majma-ut-Tavarikh of Khwaja Rashid-ud-Din Fazl Ullah. In some other histories the descent is traced yet further. But God alone knows the truth.
Among the Sultans of Kashghar was a certain Satuk Bughra Khan, who was converted to Islam in his early years. During his occupation of the throne, he brought over the whole country of Kashghar to the true faith. After his death, several of his descendants ruled in Kashghar, and even in Mavara-un-Nahr, until the conquest of Chingiz Khan.
[Tai Yang Khan fled from Chingiz Khan. Kushluk, son of Tai Yang Khan] took Kashghar from the vassals of the Gur Khan of Kara Khitai, who had himself taken it from the vassals of the descendants of Afrasiab. At that time Sultan Osman, of that family, was ruling in Samarkand and in the greater part of Mavara-un-Nahr. What passed between him and Khwarizm Shah is to be found in every history.
The rebellion of Kushluk and the conquest of Kashghar by the Moghuls, I have copied from the Jahan-Kushai, as it stands [there].
