The Chahar royal family kept favorable relations with the Qing imperial family until Makata gege, who was a daughter of Hong Taiji and married to the Chahar Mongol prince, died in 1663. After Abunai showed disaffection with Manchu Qing rule, he was placed under house arrested in 1669 in Shenyang and the Kangxi Emperor gave his title to his son Borni. Abunai then bid his time and then he and his brother Lubuzung revolted against the Qing in 1675 during the Revolt of the Three Feudatories, with 3000 Chahar Mongol followers joining in on the revolt.
