History
During the early Zhou dynasty, the Xuchang region was granted to the Xu family (Xǔ (許/许)) of the Jiang surname and became the State of Xu, ruled by Xu Wenshu. During the Spring and Autumn and Warring States period, Xuchang was successively occupied by the states of Zheng and Chu, and the Xu family was later relocated to Ye County by the Chu state.

Xuchang served as the warlord Cao Cao's de facto capital during the late Eastern Han dynasty. After finding the old capital Luoyang ravaged by war, Cao moved the imperial court and Emperor Xian to what is now Xuchang in 196.

In 220, Cao Cao's son and successor Cao Pi officially declared the city as the capital of the newly established state of Cao Wei. The city was renamed "Xuchang" taken to mean "Xu Rising". The Wei emperors held court at Xuchang until the capital was moved to Luoyang in the 220s.
