Overview
Ömkhei, a grandson of the Setsen Khan Norov, fled with the eastern Khalkha to Xilingol during the catastrophic Dzungar invasion of 1688 and pledged fealty to the Kangxi Emperor. He held the Setsen Khan title from 1691 to 1709 and was among the most prominent of the Khalkh princes who participated in the Dolonnuur Assembly of 1691 and formally submitted to Kangxi Emperor's authority, accepting Qing suzerainty in exchange for protection against further Dzungar aggression. His submission was the beginning of the Qing period of Mongolian history.
Rise to Power
Ömkhei belonged to the Setsen Khan house founded by Sholoi. When Galdan Khan's invasion of 1688 shattered Khalkha, the Setsen Khan aimag changed hands rapidly: Norov died in 1688 and Ilden Ravdan held the title until 1690. Ömkhei succeeded in 1691, the year of the Dolonnuur Assembly.
Rule and Achievements
Ömkhei's reign was defined by crisis and survival:
- In 1688, Galdan's invasion swept through Khalkh Mongolia with devastating force. The Setsen Khan aimag, in the eastern portion of Khalkh, was among the areas most affected by the Dzungar campaign
- Ömkhei fled south with his people to Xilingol, joining the mass of Khalkh refugees seeking imperial protection
- He participated in the Dolonnuur Assembly of 1691, where Kangxi Emperor personally received the submission of the Khalkh princes. At this assembly, the Khalkh nobles accepted Qing administrative incorporation, with their titles and ranks confirmed within the Qing banner system
- After Qing forces defeated Galdan at the Battle of Jao Modo in 1696, the Khalkha could return to their lands under Qing administration
- Held the Setsen Khan title until 1709, when his eldest son Günchin succeeded him
Legacy
Ömkhei's participation in the Dolonnuur submission was one of the defining acts in Mongolian history, marking the integration of Outer Mongolia into the Qing imperial system. The decision he and the other Khalkh princes made in 1691 was, in the short term, essential for survival — the Qing defeat of Galdan vindicated the strategy. In the longer term, it ended Mongolian political independence until the collapse of the Qing dynasty in 1911-1912. Ömkhei is remembered as one of the khan-nobles who navigated the most dangerous period in Khalkh history and ensured the survival of the Mongolian people and their culture.
