Ejei Khan

Erke Khongghor, alternatively known as Ejei, (?–1641) was the last khagan of the Northern Yuan dynasty, ruling briefly from 1634 to 1635. He was the son of Ligdan Khan. The Northern Yuan dynasty, which existed as remnants of the Yuan dynasty retreating north to the Mongolian Plateau after 1368, was defeated by the Later Jin dynasty in 1635 and thus formally came to an end.
