Northern Fujiwara
Yoritomo soon turned on Yoshitsune, who was initially harbored by Fujiwara no Hidehira, the grandson of Kiyohira and the "de facto" ruler of northern Honshu. In 1189, after Hidehira's death, his successor Yasuhira attempted to curry favor with Yoritomo by attacking Yoshitsune's home. Although Yoshitsune was killed, Yoritomo still invaded and conquered the Northern Fujiwara clan's territories. In subsequent centuries, Yoshitsune would become a legendary figure, portrayed in countless works of literature as an idealized tragic hero.
