Chang Yŏnu
Goryeo government official

Chang Yŏnu (Korean: 장연우; Hanja: 張延祐; ? – January 5, 1016) was a Korean civil official who served the Goryeo dynasty. He fought in the second conflict in the Goryeo–Khitan War.
Biography
Chang Yŏnu was the son of Chang Yu (장유; 張儒), of the Heungdeok Chang clan. Chang Yu worked in the Department of Visiting Guests (객성; 客省; kaeksŏng), during the reign of King Gwangjong. Chang Yŏnu is thought to have been born around the time of the reign of Gwangjong.
In 1010, Chang Yŏnu was serving as the deputy minister of War (병부시랑; 兵部侍郞; pyŏngbu sirang) when he was appointed as the haengyŏng tot'ongbusa (행영도통부사; 行營都統副使) of the 300 thousand strong Goryeo army led by Kang Cho sent to defend against the invading Khitans. The Goryeo army was defeated near Tongju by the Khitans, with Kang being captured and later killed. Chang survived the battle and fled southwards with King Hyeonjong to Naju in 1011. He was appointed as the superintendent of the Censorate (판어사대사; 判御史臺事; p'anŏsadaesa) for his service to the king.

Why this record matters
“Chang Yŏnu” is worth following because a concise public description often conceals a longer documentary argument. Here, Chang, Yŏnu and Goryeo provides the most credible route into that argument.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Mar 26, 2026. The linked authority identifier is Q21575362. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1016, 1010 and 1011.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
