Rinchinbal Khan, Emperor Ningzong of Yuan

Emperor Ningzong of Yuan (Chinese: 元寧宗, 1326 – 1332), also known as Rinchinbal (Classical Mongolian: Rinčinbal; Khalkha Mongolian:Ринчинбал "Rinchinbal" from Tibetan rin chen dpal) was the Emperor of China and ruled as Emperor or Khaan of the Yuan Dynasty, khanate of Mongol Empire.

He was the second son of Kuśala Khutughtu Khan 和世琜/元明宗 and a younger brother of Toghun Temür妥欢贴睦尔/元惠宗. He was mothered by Babusha of the Naiman tribe when his father lived in exile in Central Asia.

When his father Kuśala died (was supposedly killed with poison by El Temür 燕帖木儿 and was succeeded by Kuśala's younger brother Tugh Temür 图贴睦儿/元文宗, Rinchinbal was appointed to Prince of Fu. Although Tugh Temür Khan had a son named El Tegüs when he died in 1332, his widow and El Tegüs's mother Budashiri Khatun respected Tugh Temür's will of making 元明宗 Kuśala's son succeed the throne instead of El Tegüs.

The de facto ruler El Temür resisted letting Kuśala's eldest son Toghun Temür 元惠宗 accede to the throne since he was suspected of having poisoned his father Kuśala. While Toghun Temür was kept far away from the capital Dadu, infant Rinchinbal was in Dadu and had became favored by Tugh Temür 元文宗. Thus El Temür decided to install Rinchinbal as grand-khan, but he died two months later, aged only seven.

El Temür again asked Budashiri to install El Tegüs but was declined. He had no choice but to invite Toghun Temür 元惠宗 back from far-away Yunnan.
