Tianshui revolts

The Tianshui revolts refer to the rebellions that broke out in the southern part of Liang Province (covering parts of present-day Gansu and Shaanxi) in the spring of 228 during the Three Kingdoms period of China. Military forces from the state of Shu Han, led by their chancellor-regent Zhuge Liang, planned to seize control of Chang'an, a strategic city in Shu's rival state, Cao Wei. The three commanderies of Nan'an, Tianshui, and Anding were captured by Shu forces, but these territorial gains were later lost after the Battle of Jieting. As mentioned in the biography of the Wei general Zhang He: "The commanderies of Nan'an, Tianshui and Anding rebelled and defected to (Zhuge) Liang, (Zhang) He pacified all of them."
