Yesün Temür Khan (Classical Mongolian : Yesün temür qaɤan; Khalkha Mongolian : Есѳнтѳмѳр хаан Yösöntömör haan) was the tenth grand-khan of the Mongol Empire (Dai-ön Ulus/Yuan Dynasty) who reigned from 1323 to 1328. In Chinese, he is known as the Taiding Emperor for era name. It is likely that he was the Great Khan visited by the Franciscan monk Odoric, who left an excellent record of his travels.
He was born to Kamala in Mongolia in 1293 . Kamala was the eldest son of Crown Prince Jinggim , who was presumed heir to his father Khubilai Khan. Kamala was appointed as Jinong in 1292 after Jinggim's death, but he lost the race for successor to his younger brother Temür. Khanship was assumed by Temür, Darmabala and their sons and grandson, so Kamala and his son Yesün Temür were out of the race. As Jinong, Kamala owned Mongolia north of the Gobi Desert and enshrined Chinggis Khan in the Four Great Ordo. In 1302 Kamala died and Yesün Temür took over as Jinong.
In 1323 when Shidibala Gegeen Khan was assassinated by Grand Censor Tegshi , Yesün Temür was backed up by the rebellious group since he was mothered by Buyan Kelmish of the Khunggirad clan. In response he ascended to the throne at the great ordo of Chinggis Khan in Mongolia. But he sent troops to Dadu and executed rebellious officers before he entered Dadu because he feared to become a puppet of them.
He did nothing significant for his five year reign. He left the empire's governance to his Muslim aide Dawlat Shah . He suddenly died in Shangdu in 1328. His son Ragibagh was installed by Dawlat Shah but was defeated by his rival Tugh Temür in a year.
