Rinchinbal Khan

Rinchinbal (1326–1332), temple name Emperor Ningzong, was the second son of Khutughtu Khan Kusala, Emperor Mingzong, and a younger brother of Toghon Temür. After his father's death in 1329 he was made Prince of Fu and kept at court by his uncle Tugh Temür, Emperor Wenzong.

When Wenzong died in 1332 his widow Budashiri, honouring his deathbed wish to restore Kusala's line, had the six-year-old boy enthroned rather than recall the exiled Toghon Temür. Rinchinbal reigned barely seven weeks and died that December.
