Revolt of the Three Feudatories
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.
