Ligdan Khan
The Inner Mongolian Chahar leader Ligdan Khan, a descendant of Genghis Khan, opposed and fought against the Qing until he died of smallpox in 1634. Thereafter, the Inner Mongols under his son Ejei Khan surrendered to the Qing and he was given the title of Prince (Qin Wang, 親王). The Inner Mongolian nobility now became closely tied to the Qing royal family and intermarried with them extensively. Ejei Khan died in 1661 and was succeeded by his brother Abunai. After Abunai showed disaffection with Manchu Qing rule, he was placed under house arrest in 1669 in Shenyang and the Kangxi Emperor gave his title to his son Borni.
