In late 15th century, Mirza Abu Bakr Dughlat from the Dughlat tribe founded an independent kingdom for himself from the fragmentation of Moghulistan. The kingdom encompassed Hotan and Kashgar. However, he was deposed in the 1510s by Sultan Said Khan who founded the Yarkand Khanate. While attempting to flee to Ladakh, Abu Bakr was intercepted and killed. His tomb is located about north of modern day town of Xaidulla.
