Manduhai Tsetsen Hatan or Manduhai the Wise Queen's role in Mongolian history was in ensuring Batmunkh Dayan Khan's success. Grand Khan Manduul, Genghis Khan's twenty-seventh successor, died in 1467 as the result of a war against his great-nephew and their Bold Jonon , and the latter in his turn was assassinated before he could be proclaimed khan (1470). 

Manduhai Tsetsen Hatan or Manduhai the Wise Queen's role in Mongolian history was in ensuring Batmunkh Dayan Khan's success. Grand Khan Manduul, Genghis Khan's twenty-seventh successor, died in 1467 as the result of a war against his great-nephew and their Bold Jonon , and the latter in his turn was assassinated before he could be proclaimed khan (1470). 

 Of the once numerous Khubilaid family descendants of Genghis through Khubilai Khan was left Dayan, the son of Bold Jonon, who was deserted by everyone, even his mother, who had remarried. Manduul's young widow, Manduhai, took the child under her protection and proclaimed him Khan. She herself then assumed command of the loyal Mongols and inflicted a defeat on the Oirad.

In 1481, she married young Dayan. From 1491-92, this heroic woman, whose exploits recall those of Ouleun-ekhe, Genghis Khan's mother, was again depicted at the head of an army which repulsed the Oirad. It is to her that tradition gives credit for having overthrown Oirad supremacy and restored hegemony to the eastern Mongols (1970: 509).

Little else is known about Manduhai, although Haworth mentions she had seven sons, including two sets of twins (1876: 372-3). She is also mentioned in the Mongolian chronicle, Erdeniin Tovch written by Sagan Setsen in 1662 (Krueger 1967). While not dismissing her entirely, the Russian scholar Pokotilov refers to her marriage to the young Batmunkh as a "poetical legend" (1976: 79).

Whatever the true facts surrounding her, what is central to our understanding of Manduhai and the role she plays in socialist era history books are two basic points. First, by marrying Batmunkh, she managed to keep the Golden Lineage (as Genghis's descendants are known) in a position of actual, as well as nominal, power. Second, in her campaigns against the Oirad, she set the stage for Batmunkh's attempt at re-uniting the Mongols. And thus, under socialism was credited with halting 'feudal disintegration'. Batmunkh Dayan Khan (1470-1 543) continued the campaigns begun by Manduhai, and ruled briefly as Khan over the united Mongol tribe.
