Bogd Gegen

The Jebtsundamba Khutuktu (Chinese:哲布尊丹巴呼圖克圖, Mongolian: Жавзандамба хутагт, Jawzan Damba Khutagt Mongolian pronunciation: [tɕawtsaɴ tampa χʊʰtaxt]; Tibetan: རྗེ་བཙུན་དམ་པ་ཧུ་ཐུག་ཐུ་, Wylie: rje btsun dam pa hu thug tu, THL Jétsün Dampa Hutuktu "Mongolian Holy Precious Master") are the spiritual heads of the Gelug lineage of Tibetan Buddhism in Mongolia. They also hold the title of Bogd Gegeen, making them the top-ranked lamas in Mongolia.

The first Jebtsundamba, Zanabazar (1635–1723), was identified as the reincarnation of the scholar Taranatha of the Jonang school of Tibetan Buddhism. Zanabazar was the son of the Tüsheet Khan Gombodorj, ruler of central Khalkha Mongolia, and himself became the spiritual head of the Khalkha Mongols.

On May 29, the Jebtsundamba Khutukhtu paid homage to the Kangxi Emperor in 1691 at Dolonnor.

Like Zanabazar, the 2nd Jebtsundamba Khutughtu was a member of Mongolia's highest nobility and direct descendant of Genghis Khan. After Chingünjav's rebellion and the demise of the second Jebtsundamba Khutugtu, the Qianlong Emperor decreed in 1758 that all future reincarnations were to be found from among the population of Tibet.
