Editing Hebei (section)

===Tang and Five dynasties===
During the [[Tang dynasty]] (618–907), the area was officially called Hebei for the first time. The [[Yan (An–Shi)|Great Yan]] State was established in Hebei from 756 to 763 during the [[An Lushan Rebellion]]. After the rebellion, [[Lulong Jiedushi]] retained its autonomy from Tang during most of the 9th century. During the late [[Five Dynasties and Ten Kingdoms period]], Lulong was fragmented among several regimes including the short-lived [[Yan (Five Dynasties period)|Yan]]. It was eventually annexed in 913 by [[Li Cunxu]], who established the [[Later Tang]] (923–936). Emperor [[Gaozu of Later Jin|Gaozu of the Later Jin dynasty]] ceded much of northern Hebei to the [[Khitan people|Khitan]] [[Liao dynasty]]. This territory, called the [[Sixteen Prefectures]] of Yanyun, became a weakness in the Chinese defense against the Khitans for the next century because it lay within the [[Great Wall]].
