Khutughtu Khan (
Classical Mongolian: Qutuɤtu qaɤan;
Khalkha Mongolian: Хутагт хаан Hutagt haan), born Kuśala (Qošila, Küsala, Küsele, Хѳслэн Höslen), was the
Emperor of China and ruled as emperor of the
Yuan Dynasty,
khanate of
Mongol Empire.He was the eldest son of
Khayishan Külüg Khan. Since the Khayishan administration was founded on the unstable balance between Khayishan, his younger brother
Ayurbarwada and their mother Dagi of the Khunggirad clan, Khayishan appointed Ayurbarwada as Crown Prince on the condition that he would pass the status to Kuśala after succession. However, when Khayishan suddenly died and Ayurbarwada succeeded to the throne in 1311, Dagi, Temüder and other members of the Khunggirad faction installed Ayurbarwada's son
Shidibala instead of Kuśala because his mother came from the Ikires clan, not the Khunggirad clan. He was relegated to
Yunnan but fled to Esen Bukha-ruled Chaghatai Ulus in
Central Asia after a failed revolt in
Shaanxi.
