 According to tradition, after King Wu of Zhou conquered the Shang dynasty in 1046/45 BC, he enfeoffed a descendant of the Yellow Emperor at the settlement of Ji, in modern Beijing municipality.Ji was conquered by the neighbouring state of Yan in the 7th century BC, and the people of Ji adopted the name of their former state as their surname.The most prominent clan ("junwang", 郡望) of the Ji surname in history is that of the Neihuang Commandery, in modern Henan province.
