トゥグルク・ティムール
Arguments about succession resulted in the breakup of the Mongol Empire in Asia into the Chagatai Khanate in Central Asia, Yuan Dynasty (1279–1368) in China, Ilkhanate in Persia, and Golden Horde in Russia, which waged destructive wars with one another. After the Han Chinese united and expelled the Mongols from China, establishing the Ming Dynasty (1368–1644), Yuan Mongol refugees, principally of the Borjigin clan, migrated to the eastern Chagatai Khanate. Those Mongols allied with the nomadic Buddhist, Christian and Shamanist rebels of the Issyk Kul and Isi areas against the Chagatai Khan Tarmashirin in the 1330s upon his conversion to Islam. This Khan and his heirs ruled a region of nomadic tribesmen and oasis-dwellers from the 14th to the 17th century. Moghulistan, which had formed the eastern portion of the Chagatai Khanate, became independent in 1347 under the Chagatayid named Tughlugh Timur. There is no accepted date for the dissolution of the Chagatai Khanate, although some historians mark it with the ascendance of Tughlugh. There were few contemporary histories of Moghulistan, in contrast to the well-documented Timurid Empire; most of modern knowledge about the region comes from the Tarikh-i-Rashidi.
