林丹汗
By the reign of Ligdan Khan (r. 1604–1634), the Northern Yuan tumens had ceased to function as a unified entity. Ligdan only controlled the Chahar tumen and the Khalkha and Oirat Mongols no longer obeyed his authority. Ligdan built a new capital in Chahar land known as Chaghan Baishin (White House) and promoted the building of Buddhist monasteries, translation of Tibetan literature, and trade with the Ming dynasty.
