Dayan Khan
When her husband died in 1478, Mandukhai had the choice of marrying Une-Bolad or taking the Mongols to Ming Dynasty to be vassals. Instead, Mandukhai elected to rule instead and recovered Batumöngke, the missing son of Bayan-Möngke, to ascend the throne at the royal shrine kept by the Chahar with the title Dayan Khan. Because Dayan Khan was a child at the time of his ascension, Mandukhai became the empire's de facto ruler while simultaneously raising Dayan Khan to become an effective ruler. Together, they united the entire Mongols, restoring order.
