Editing Hebei (section)

===Qin and Han dynasties===
The [[Qin dynasty]] unified China in 221 BC. The [[Han dynasty]] (206 BC – 220 AD) ruled the area under two provinces, [[You Prefecture]] in the north and [[Ji Province]] in the south. At the end of the Han dynasty, most of Hebei was under the control of [[warlord]]s [[Gongsun Zan]] in the north and [[Yuan Shao]] further south. Yuan Shao emerged as the victor of the two, but he was defeated by [[Cao Cao]] in the [[Battle of Guandu]] in 200. Hebei came under the rule of the [[Cao Wei|Kingdom of Wei]], established by the descendants of Cao Cao.
