Wei Guan

Wei Guan (220 – 25 July 291), courtesy name Boyu, was a Chinese military general and politician of the state of Cao Wei during the Three Kingdoms period of China. He served under the Jin dynasty after the end of the Three Kingdoms period. Early life and career Wei Guan was from Anyi County, Hedong Commandery, which is located west of present-day Xia County, Shanxi. His father Wei Ji was a high-ranking Wei official and marquis, who died in 229. Wei Guan inherited his father's peerage, and when he grew older became an official. Throughout the years, he became known for his capability and was continuously promoted. After Cao Huan became emperor, he became an Official of Justice, and was known for his strength in logical thinking. When the Wei regent Sima Zhao ordered the generals Zhong Hui and Deng Ai to attack Wei's rival state Shu Han in 263, Wei Guan served as Deng Ai's deputy. After the fall of Shu that year, Zhong Hui planned a rebellion, and the first step of his preparation was to falsely accuse Deng Ai of treason. Sima Zhao, believing Zhong Hui's accusations, ordered Deng Ai arrested, and Zhong Hui in turn ordered Wei Guan to arrest Deng Ai, hoping that Wei Guan would fail and be killed by Deng Ai so that he could further affirm his accusations against Deng Ai. Wei Guan knew this, so he surprised Deng Ai in the middle of the night and arrested him. When Zhong Hui rebelled later, Wei Guan pretended to be seriously ill, so Zhong Hui lowered his guard against Wei Guan. Later, Wei Guan participated in inciting the soldiers to start a mutiny against Zhong Hui and end the rebellion. Fearful that Deng Ai would then retaliate against him, he had Deng Ai tracked down and killed. When Du Yu publicly denounced Wei Guan, instead of becoming angry and retaliate against Du Yu, Wei Guan visited him and apologised. He also declined a larger fief that Sima Zhao was ready to bestow on him for his accomplishments. Career during the Jin dynasty In 265, Sima Zhao died and was succeeded as regent by his son Sima Yan (Emperor Wu). In February 266, Sima Yan usurped the throne from Cao Huan, thus ending the Cao Wei state and establishing the Jin dynasty. Throughout Emperor Wu's reign, Wei Guan continued to be an important official and general, serving in a variety of roles capably. As a result, one of his brothers and one of his sons were granted marquis titles.
