Cao Xun was a figure of Cao Wei. Wikidata gives his Chinese label as Cao Xun, in the traditional form of the character xun, and records his death in 249 and his occupation as political figure. The Chinese Wikipedia article is titled Cao Xun in the simplified form. The two are the same name, so the title stays as it is.[1][2]
Family and office
The Chinese Wikipedia article says he was from Qiao county in the commandery of Qiao, a son of Cao Zhen and a younger brother of Cao Shuang, and that he was enfeoffed as Marquis of Wansui Pavilion. After Emperor Cao Fang came to the throne, Cao Shuang took the regency as general-in-chief and appointed Cao Xun general of the guards, with the right to go in and out of the palace.[2]
The coup at the Gaoping tombs
In the tenth year of Zhengshi (249), Cao Xun went with Cao Shuang and others when Cao Fang visited the Gaoping tombs. Sima Yi took the chance to launch a coup and seized control of Luoyang, and Cao Xun was dismissed. Soon afterwards Cao Shuang and all his brothers were beheaded on a charge of treason, and Cao Xun's three clans were exterminated. The article cites the Wei zhi biography of Cao Shuang as its source.[2]
