Külüg Khan (Mongolian: Хүлэг; Mongolian script: ; ), born Khayishan (Mongolian: Хайсан ; , , meaning "wall"), also known by the temple name Wuzong (Emperor Wuzong of Yuan; ) (August 4, 1281 – January 27, 1311), Prince of Huaining (懷寧王) in 1304–1307, was an emperor of the Yuan dynasty of China. Apart from Emperor of China, he is regarded as the seventh Great Khan of the Mongol Empire, although it was only nominal due to the division of the empire. His name means "warrior Khan" or "fine horse Khan" in the Mongolian language. Early life He was the first son of Darmabala and Dagi of the influential Khunggirad clan, and the full brother of Ayurbarwada. He was sent to Mongolia to assume an army that defended the western front of the Yuan against Kaidu, de facto ruler of the Chagatai Khanate, and other princes in Central Asia under him. In 1289, Khayishan's force was nearly routed and the Kipchak commander, Tutugh, rescued him from capture by Kaidu's army. In 1301 he clashed with Kaidu, who died from a battle wound. In recognition of the great success, Külüg Khan was given the title of Prince Huaining (懷寧王) in 1304. When Chapar attacked Duwa, Temür helped the latter and sent an army under Khayishan. In 1306 Khayishan forced Melig Temür, a son of Ariq Böke, who was aligned himself with Kaidu to accept a surrender in the Altai Mountains and pushed Kaidu's successor Chapar westward. For these military achievements he gained a high reputation among Mongol princes and non-Mongol corps. Since his uncle Temür Khan did not have a male heir, he was considered a major candidate for the emperor. Enthronement In 1307 when Temür Khan died, he returned eastward to Karakorum and watched the situation. Temür's widow Bulugan of the Bayaud tribe had kept away the Khunggirad-mothered brothers of Khayishan and Ayurbarwada and attempted to set up Ananda, a Muslim cousin of Temür, who was the prince of An-hsi. Her alliance was supported by some senior officials of the Secretariat under Aqutai. They made Bulugan regent and intended to put Ananda on the throne. Ananda was a popular prince who successfully protected the province of the Yuan against the Ögedeid and Chaghatayid armies and had a bulk of the imperial army under him in An-hsi. But he lacked of military power in the imperial capital city and was a Muslim opposed
