護国戦争
Cai E is regarded as the founder of the clique when at the request of Liang Qichao in 1915, he declared Yunnan's opposition to Yuan Shikai's monarchy. Cai died from natural causes shortly after the successful National Protection War. His chief lieutenant, Tang Jiyao, took over Yunnan and demanded that the National Assembly be restored. When this was accomplished, Yunnan officially reunified with the national government but kept its provincial army separate due to the Beiyang Army's grip in Beijing politics.
