Yesün Temür Khan, Emperor Taiding of Yuan

Yesün Temür Khan (Classical Mongolian: Yesün temür qaγan; Khalkha Mongolian: Есөнтөмөр хаан "Yösöntömör haan") was the Emperor of China and ruled as Emperor or Khaan of the Yuan Dynasty, khanate of Mongol Empire who reigned from 1323 to 1328. In Chinese, he is known as the Emperor Taiding from his era's name. It is likely that he was the emperor visited by the Franciscan monk Odoric, who left an excellent record of his travels.

He was born in Mongolia in 1293 to Kamala, the eldest son of Crown Prince Zhenjin, who was presumed heir to his father Kublai Khan. Kamala was appointed as Jinong in 1292 after Zhenjin'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 Genghis 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 Genghis 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.
