Dayan Khan
In the mid-14th century, they lived in Liaoyang in Northeast China. In 1375, Naghachu, Uriankhai leader of the Mongol-led Northern Yuan dynasty in Liaoyang, invaded the Liaodong Peninsula to restore the Mongols to power. Although he continued to hold southern Manchuria, the Ming military campaign against Naghachu ended with his surrender in 1388. After the rebellion of the northern Uriankhai people, they were conquered by Dayan Khan in 1538 and mostly annexed by the northern Khalkha. Batmunkh Dayan Khan dissolved Uriankhai tumen.
