Muhammad Amin Bughra
Qing imperial authority collapsed in 1912. During the Republican era in China, warlords and local ethnic self-determination movements wrestled over control of Xinjiang. Abdullah Bughra, Nur Ahmad Jan Bughra, and Muhammad Amin Bughra declared themselves Emirs of Khotan during the Kumul Rebellion. Tunganistan was an independent administered region in the southern part of Xinjiang from 1934 to 1937. The territory included the oases of the southern Tarim Basin; the centre of the region was Khotan. Beginning with the Islamic rebellion in 1937, Hotan and the rest of the province came under the control of warlord Sheng Shicai. Sheng was later ousted by the Kuomintang.
