林丹汗
During the Qing's Emperor Hong Taiji's (1592-1643) campaign against the last Mongol khan Ligdan Khan, he started the sponsorship of Tibetan Buddhism to gain support. According to the Manchu historian Jin Qicong, Buddhism was used by Qing rulers to control Mongolians and Tibetans; it was of little relevance to ordinary Manchus in the Qing dynasty.
