Batumöngke Dayan Khagan

Who was Batumöngke Dayan Khagan?

Dayan Khan was a Mongol khan who reunited the Mongols under Chinggisid supremacy in the Northern Yuan Dynasty in Mongolia. His reigning title, "Dayan", means the "Great Yuan", as he enthroned himself as Great Khan of the Great Yuan, though the Yuan Dynasty, the principal khanate of the Mongol Empire, had already been overthrown by the native Chinese Ming Dynasty in China a century ago. He is remembered as one of the most glorious Mongolian Emperors.

Dayan Khan and his queen, Mandukhai, eliminated Oirat power and abolished the taishi system used by both local and foreign warlords. Dayan Khan's victory at Dalan Tergin reunified the Mongols and solidified their corporate identity as Chinggisid people. His decision to divide the Six tumens of Eastern Mongolia as fiefs for his sons created decentralized but stable Borjigin rule over Mongolia for a century.
