三藩之乱
In 1668, during the reign of the Kangxi Emperor, the Viceroy of Huguang was abolished and merged into the Viceroy of Sichuan, which was then renamed "Viceroy of Chuan-Hu" (川湖總督) and based in Jingzhou. In 1670, the Viceroy of Chuan-Hu relocated to Chongqing. Four years later, perhaps coinciding with the Revolt of the Three Feudatories, the Viceroy of Chuan-Hu reverted to pre-1668, separating into the Viceroy of Huguang and Viceroy of Sichuan. In 1680, the Kangxi Emperor merged the Viceroy of Sichuan with the Viceroy of Shaanxi under the "Viceroy of Chuan-Shaan" (川陝總督), with its headquarters in Xi'an. In 1718, a separate Viceroy was created for Sichuan, so the Viceroy of Chuan-Shaan stopped managing Sichuan. However, these changes were reversed in 1721.
