In ancient China, Henei ("Inside the Yellow River") referred to the land north of the lower Yellow River. The commandery was established duringEmperor Gaozu of Han's reign. It administered 18 counties: Huai (懷), Ji (汲), Wude (武德), Bo (波), Shanyang (山陽), Heyang (河陽), Zhou (州), Gong (共), Pinggao (平皋),Zhaoge (朝歌),Xiuwu (脩武),Wen (溫),Yewang (野王), Huojia (獲嘉), Zhi (軹), Qinshui (沁水), Longlü (隆慮) andDangyin (蕩陰).

Over the course ofJin andNorthern Wei dynasties, the Han-era Henei Commandery was divided into four commanderies including Henei, Linlü (林慮), Ji and Wude. According to theBook of Wei, the population was 42,601, 55,714, 102,997, and 52,372 respectively.[3]
In earlyKaihuang era, the much reduced Henei Commandery was merged into Huai Prefecture (懷州).[4] Later, Henei Commandery became an alternative name of Huai. In 742 AD, the prefecture had 5 counties, and a population of 318,126.[5]
