High Quality Content by WIKIPEDIA articles! In earlier times, only members of the Imperial Family could be appointed sessh . Kojiki reported that Emperor jin was assisted by his mother, Empress Jing , but it is doubtful if it is a historical fact. The first historical sessh was Prince Sh toku who assisted Empress Suiko. The Fujiwara clan was the primary holders of the kampaku and sessh titles. More precisely those titles were held by the Fujiwara Hokke (Fujiwara north family) and its descendants, to which Fujiwara no Yoshifusa belonged. In 858 Fujiwara no Yoshifusa became sessh . He was the first not to belong to the Imperial house. In 876 Fujiwara no Mototsune, the nephew and adopted son of Yoshifusa, was appointed to the newly created office of kampaku. After Fujiwara no Michinaga and Fujiwara no Yorimichi, their descendants held those two office exclusively. In 12th Century, there were five families among the descendants of Yorimichi called Sekke: Konoe family, Kuj family, Ichij family, Takatsukasa family and Nij family.
