Abdurashid Khan

In 1538, Abdurashid Khan concluded a treaty with Uzbek Chief Ubaydullah Sultan, who ruled the Khanate of Bukhara at the time (1533–1539).

During the negotiations with Ubaydullah Sultan, a Naqshbandi Sufi teacher Ahmad Kasani (1462–1542), known as Makhdum-i ' Azam (the Great Master) came to Kashgar from Samarkand and was granted land there.

The descendants of Makhdum's eldest son Muhammad Amin (died in 1598), or Ishan Kalan, the founder of the Ishkiyya branch of the Sufi order (tariqa) Naqshbandi khojagan, established themselves in Kashgar and became known as the Aq Taghliks, those of the Tian Shan (or "White Mountains").

The descendants of his second son, Ishaq Wali (died in 1599), founder of branch Ishakiyya of the Sufi order Naqshbandi khojagan, established themselves in Yarkand and became known as the Kara Taghliks, those of the "Black Mountains", i.e. the Pamirs, Karakorum and Kunlun.

Between 1541 and 1546, the historian and ruler of Kashmir on behalf of Babur's descendants, Mirza Muhammad Haidar Dughlat, wrote a book "Tarih-i-Rashidi" (The History of Rashid).
