When Yuan Shikai proclaimed himself emperor of China in December 1915, Tang announced the independence of Yunnan with the support of Cai E, Li Liejun and others. He was a prominent leader of the army against Yuan Shikai during the National Protection War, and with Yuan’s death Tang emerged as one of the most powerful military leaders in southern China and extended his power base into Guangxi and Sichuan provinces.
