The Northern Yuan was a dynastic state ruled by the Mongol Borjigin clan based in the Mongolian Plateau. It existed as a rump state after the collapse of the Yuan dynasty in 1368 and lasted until its conquest by the Jurchen-led Later Jin dynasty in 1635, which was later renamed as the Qing dynasty. The Northern Yuan dynasty began with the retreat of the Yuan imperial court led by Toghon Temür to the Mongolian steppe. This period featured factional struggles and the often only nominal role of the Great Khan.
