Ragibagh (Mongolian:ᠷᠠᠴᠠᠪᠠᠭ Рагибаха[1] or ᠷᠠᠵᠠᠪᠠᠭ Ражабаг;[2][3] Chinese: 阿剌吉八; Arigabag), also known by his era name as the Tianshun Emperor of Yuan (Chinese: 元天順帝), was a son of Yesün Temür (Taiding Emperor) who was briefly installed to the throne of the Yuan dynasty of China in Shangdu in 1328.
In August 1328 when Yesün Temür suddenly died in Shangdu, he was installed by the powerful Muslim officer Dawlat Shah there in the next month.
In the eighth month, the Mongolized Qipchaq commander El Temür, who was stationed in Dadu, launched a coup and called for installation of Khayishan's son.
At the time, most of Ragibagh's army were involved on the Great Wall front, and the Shangdu court was compelled to surrender on the very next day.
[6] Dawlat Shah and most of the leading loyalists were taken prisoner and later executed by the Dadu faction after surrender; but Ragibagh is said to have disappeared after that, evidently murdered.
