The Kujo clan (九条家 Kujō-ke) was a branch of the Fujiwara family. As one of the five regnet houses, the Kujo clan monopolized the posts of Sessho and Kampaku along with Konoe, Takatsukasa, Nijo and Ichijo clans.
By the recommendation of Minamoto no Yoritomo, Fujiwara no Kanezane founded the clan. The fourth shogun Yoritsune and the fifth shogun Yoritsugu of the Kamakura shogunate came from this clan.
