The historian Mirza Muhammad Haidar, in 1546, called the eastern part of the country the "Eastern Khanate or Uyghurstan" in his famous book "Tarikh-i- Rashidi", written in Kashmir. The capital of this state was Yarkand, and it was known by the names "mamlakati Saidiya", "mamlakati Yarkand", and "mamlakati Moghuliya" in Iranian sources. The last name however was not accurate, because by this time the nomad state of Moghulistan had collapsed. It was eliminated during the fifteenth and sixteenth centuries by nomadic tribes of Kyrgyz, Kazakhs and Jungars, that captured all the Moghul lands north of "Tangri Tagh". The remnants of the Moghuls ( about 5,000 families mostly from "Barlas", "Churas" and "Arlat" tribes) moved to Kashgaria and mixed with the local 1,000 000 Uyghur population, although a group of the Moghuls, numbering 30,000 men, joined Babur, a descendant of Timur the Great through his father Omar Sheikh Mirza, and a descendant of Chagatai Khan through his mother Kutluk Nigar Khanum, a daughter of the Moghul Yunus Khan, in Kunduz, in 1512, and helped him in his invasion of India. The Babur state in India was known as the Moghul Empire, and this state recognized Yarkand Khanate in 1529, ( when Babur and Sultan Said Khan peacefully settled issue around Badakhshan, that was claimed by both cousins as their hereditary Land) as it did the Shaybanid state in "Maverannahr", in 1538.
