Yu Province (豫州) was a central province located in the heart of the Central Plains. Covering parts of modern Henan and Anhui provinces, it was one of the most strategically important regions during the Three Kingdoms period.
Historical significance
Yu Province was one of the nine provinces of ancient China, located in the Central Plains where Chinese civilisation originated. The region was densely populated and agriculturally rich, with the Yellow River and Huai River flowing through it. Control of Yu Province was essential for any power seeking to dominate central China.
Under Cao Cao
Cao Cao gained control of Yu Province early in his rise to power. In 196, he established his base at Xu Chang in Yu Province when he welcomed Emperor Xian. The province became the core of Cao Cao’s territories, providing manpower and resources for his campaigns.
Battle of Guandu
In 200, the Battle of Guandu was fought in northern Yu Province between Cao Cao and Yuan Shao. Despite being outnumbered, Cao Cao achieved a decisive victory by attacking Yuan Shao’s supply depot at Wuchao. This battle established Cao Cao as the dominant power in northern China.
Zhuge Liang’s northern expeditions
During the 220s and 230s, Yu Province became a battleground between Cao Wei and Shu Han. Zhuge Liang launched multiple northern expeditions from Shu, aiming to capture Yu Province and restore the Han dynasty. The Wei forces, led by Sima Yi, defended the province successfully.
Battle of Wuzhang Plains
In 234, Zhuge Liang’s fifth and final northern expedition reached Wuzhang Plains in Yu Province. Sima Yi refused to engage in direct battle, preferring to wait out the Shu forces. Zhuge Liang died of illness during the campaign, and the Shu army withdrew. This marked the end of serious Shu attempts to conquer Yu Province.
Wei administration
Under Cao Wei, Yu Province was well-administered and developed. The tuntian system of military farming was implemented extensively, increasing agricultural production. The province served as a buffer against attacks from Shu Han in the west and Eastern Wu in the south.
Modern region
Today, the region of ancient Yu Province covers parts of Henan and Anhui provinces. Major cities include Zhengzhou, Kaifeng, and Bengbu. The area remains an important agricultural and population centre in central China.
