Külüg Khan (Khayishan)

Külüg Khan, born Khayishan (1281–1311), posthumously Emperor Wuzong of Yuan, was the eldest son of Darmabala and nephew of the heirless Temür Khan. He won fame commanding Yuan armies in Mongolia against Kaidu, who died of wounds in 1301, and he became Prince Huaining in 1304.

Enthroned in 1307, he named his brother Ayurbarwada crown prince, showered princes and Buddhist temples with gifts, and revived the Department of State Affairs amid fiscal trouble. He died in 1311.
