Its former name was Hengzhou (衡州, p Héngzhōu). This was the capital of a prefecture in the Tang Dynasty's Jiangnan and West Jiangnan circuits. Li Jingxuan was banished to superintendence of Hengzhou after feigning an illness and attempting to usurp control of the legislative bureau at Chang'an against the Gaozong Emperor's wishes in AD 680. Following the AD 705 coup that removed the Empress Wu Zetian from power, her ally Li Jiongxiu was also briefly demoted to superintendence of this province. During the reign of Emperor Muzong, the chancellor Linghu Chu was also demoted to this province for his underlings' alleged corruption.
In the 750s, the superintendent of Hengzhou Chen Xi'ang not only ruled his own region but also used his private army to dominate his nominal superior, the military governor Zhang Weiyi headquartered in Jing Prefecture (modern Jingzhou). Upon Zhang's replacement by the former chancellor Lü Yin in 760, however, Chen was placated and then killed in a surprise attack.
During the reign of the Tang emperor Xizong, Zhou Yue overthrew first the prefect of Hengzhou Xu Hao in 881 and then the agent of the rebel Qin Zongquan in the capital of the Qinhua Circuit at Tan Prefecture (modern Changsha) in 886. Xizong confirmed Zhou Yue in all his posts, renaming his circuit Wu'an. Xizong's brother then gave him additional authority over West Lingnan Circuit (modern Guangxi). Shortly after, in 893, Deng Chune and Lei Man attacked and killed him.
Other superintendents included Qi Ying and Xiao Ye.
After initially falling to agrarian rebels under Yang Shiyuan, Hengzhou was recovered by the lord of Wu'an Ma Yin and formed part of his power base during the collapse of the Tang. He initially supported the Later Liang, then declared himself king in his own right during the Five Dynasties and Ten Kingdoms period.
During the Revolt of the Three Feudatories, Wu Sangui declared himself Emperor of the Great Zhou and established an imperial court at Hengzhou in 1678 before dying of illness later that year. His grandson Wu Shifan then retreated to Yunnan, and the Ming recovered Hengzhou the next year.
The Battle of Hengyang (See: "Defense of Hengyang") was the longest defense of a single city of the entire Second Sino-Japanese War. When Changsha fell to the Imperial Japanese Army on June 19, 1944, Hengyang became their next target. The reorganized 11th Army, consisting of 10 divisions, 4 brigades, and over 110,000 men, assumed the task of attacking Hengyang. It was part of the Japanese Itchi-Go offensive https://en.m.wikipedia.org/wiki/Operation_Ichi-Go

The city was badly damaged during World War II and few historical buildings survive in diverse stage of reconstruction, including Shigu Academy, Dragon Tower, Confucian School on the Dongzhou Island (东洲岛) and Laiyan Pagoda.
