They brought Kelzang Gyatso with them from Kumbum to Lhasa and he was installed as the 7th Dalai Lama.[63][64] Qing protectorate over Tibet was established at this time, with a garrison at Lhasa, and Kham was annexed to Sichuan.[65] In 1721, the Qing established a government in Lhasa consisting of a council (the Kashag) of three Tibetan ministers, headed by Kangchennas. The Dalai Lama's role at this time was purely symbolic, but still highly influential because of the Mongols' religious beliefs.[66]
