Uskhal Khan

From Wikipedia, the free encyclopedia

Uskhal Khan, born Tögüs Temür (r. 1378-1388), was the Mongol Khan of the Yuan Dynasty in Mongolia. He used the era name Tianyuan (天元).

Although Ming sources say that he was a son of Biligtü Khan, Tögüs Temür was his younger brother^{[citation needed]}. He succeeded to the throne after Biligtü Khan died in 1378. He continued to press the Ming from the north, cooperating with Naghachu of the Jalayir in Manchuria. However, he suddenly faced a predicament in 1387 when Nagachu surrendered to Ming for a devastating famine. In 1388 he was raided by the Ming on the Buyir Nuur. In his escape to Khara Khorum, he was killed on the Tuul River by Yesüder, a descendant of Arigh Bukha. This marked the discontinuance of the Khubilai line and the rise of the Oirats.
