Dayan Khan - The Unrest of The Right Wing

The Unrest of The Right Wing

A delegation from the Three Right Wing tumens (Ordos, Tümed and Yöngshiyebü) invited Dayan Khan to rule them. Because Iburai Taishi (also known as Ibrahim), an Uighur adventurer or an Oirat/Kharchin warlord, and Mandulai dominated the area, the three tumens discontented with their power. In one skirmish raid on one of the rebel groups, the imperial army killed Ibrahim’s younger brother before that. Dayan Khan dispatched to the Three Right Wing Tumens his sons Ulusbaikh (Ulusbold) and Barsubolad Sainalag. As Ulusbold was being enthroned as jinong, he was killed in a riot and Barsubolad escaped. In revenge, Dayan khan attacked the Three Right Wing Tumens with his three Left Wing Tumens (Chakhar, Khalkha and Uriankhai), the Khorchin and the Abagha. Because a large group of the Uriankhai tumen defected to Iburai, Dayan Khan was first defeated at Turgen Stream at present-day Tumed territory.

In 1510, he crushed the Three Right Wing Tumens and killed Mandulai the Ordos elder. Iburai fled to Kokenuur (Qinghai) where he remained active to 1533. Dayan Khan dispersed the rebel Uriankhais among other 5 tumens. Instead of enslaving the Right Wing Tumens, Dayan Khan had Barsubolad enthroned as jinong (晉王) in 1513, abolishing old titles like taishi (太師) and chingsang (丞相) of the Yuan Dynasty. He exempted his soldiers from imposts and made them Darqan. According to an ancient Mongolian source, the Mongols were again peaceful thereafter thanks to the policy of Dayan Khan and his khatun Maudukhai.

With defeats of Iburai and Ismayil, Dayan and Mandukhai could remove the power of descendants of the Alans, the Kypchaks and the Hami Muslim warlords from the Northern Yuan court in Mongolia.
