Khutughtu Khan (Mongolian: Хутагт хаан; Mongolian script: ᠬᠤᠲᠤᠭᠲᠤ; Chinese: 忽都篤汗), born Kuśala (Mongolian: Хүслэн ᠬᠥᠰᠯᠡᠨ; Chinese: 和世剌; Sanskrit: कुशल, meaning "virtuous"/"wholesome"), also known by his temple name as the Emperor Mingzong of Yuan (Chinese: 元明宗; 22 December 1300 – 30 August 1329), was a son of Khayishan (Emperor Wuzong) who seized the throne of the Yuan dynasty of China in 1329, but died in suspicious circumstances six months later.

To ensure Shidebala's succession, Kusala was rewarded with the title of king of Chou and relegated to Yunnan in 1316;[2] but fled to Esen Bukha-ruled Chagatai Khanate in Central Asia, as a pro-Khayishan official advised, after a failed revolt in Shaanxi.

This ended in the victory of Tugh Temür since he secured support from most of the princes, aristocrats and warlords in the south of the Gobi Desert.

At the same time, Kuśala, with support from the Chaghadayid leaders Eljigidey and Duwa Temür, entered Mongolia from the Tarbagatai region (in the Khangai Mountains).

He also got support from princes and generals of Mongolia, and with overwhelming military power in the background, put pressure on Tugh Temür, who had already ascended the throne.

Kuśala had proceeded to appoint his own loyal followers to important posts in the Secretariat, the Bureau of Military Affairs, and the Censorate.
