Ragibagh, Tianshun Emperor

Ragibagh (1320–1328), remembered as the Tianshun Emperor, was the eldest son of Yesün Temür and was named crown prince in infancy in 1324. After his father died suddenly at Shangdu in August 1328, El Temür launched a coup at Dadu and raised Tugh Temür to the throne; the minister Dawlat Shah installed Ragibagh at Shangdu.

The War of the Two Capitals followed. Ragibagh's troops broke through the Great Wall but were routed, and Shangdu surrendered; Dawlat Shah was captured and executed, while Ragibagh vanished, evidently murdered, making him the shortest-reigning of Yuan emperors.
