Toghun Temur

Toghun Temür or Emperor Huizong of Yuan, was a son of Kuśala who ruled as Emperor of the Yuan Dynasty, and is considered the last Khan of the Mongol Empire. During the last years of his reign, the Mongols lost effective control over China to the Ming Dynasty. He was a Buddhist student of Karmapas and is considered a previous incarnation of Tai Situpa. His name means "smart/bright Khan" in the Mongolian language.
Toghun Temür was born to Kuśala when he stayed in Central Asia in exile. Toghun Temür's mother was Mailaiti, descendant of Arslan, the chief of the Qarluq tribe.
Following the civil war that broke out after Yesün Temür Khan's death in 1328, he attended his father Kuśala and entered Shangdu via Mongolia. But after Kuśala died and Kuśala's younger brother Tugh Temür was restored to the throne, he was kept from the court and was banished to Goryeo and then to Guangxi. While he was in exile, his stepmother Babusha was executed.

In 1332 when Tugh Temür died, his widow Budashiri Khatun respected his will to make Kuśala's son succeed the throne instead of his son El Tegüs. But it was not Toghun Temür but his younger half-brother Rinchinbal who became the emperor. Rinchinbal died in two months, and the de facto ruler El Temür attempted to install El Tegüs again, but it was rejected by Budashiri. As a result, Toghun Temür was summoned back from Guangxi. El Temür feared that Toghun Temür, who was too mature to be a puppet, would take arms against him since he was suspected of the assassination of Toghun Temür's father Kuśala. The enthronement of Toghun Temür was postponed for six months by El Temür. He managed to accede to the throne in 1333 when El Temür died.
