噶尔丹
The head of the Khalkha Buddhism Boghda Zanabazar, the Khalkha khans and nobles with thousands of their subjects moved in panic to Inner Mongolia, which had been integrated into the Qing dynasty. A few Khalkhas fled north of Outer Mongolia where Russia threatened to exterminate them if they failed to submit, but many submitted to Galdan Boshugtu. The Khalkha leaders sought Manchu aid in their feud with Galdan Boshugtu Khan while the Kangxi Emperor of the Qing dynasty cunningly demanded that they become his vassals as a condition for his support. Galdan demanded that the Kangxi Emperor cede him Önder Gegeen Zanagazar and Tushiyetu Khan Chahundorji. The Kangxi Emperor refused and decisive battle took place near UlaanBudan where Galdan was defeated and fled back deeper into Khalkha territory.
