Hōjō clan
The Hōjō clan was, ironically, descended from the Taira clan, which would lose to the Minamoto in the grand civil war known as the Genpei War in the 1180s; however, as a result of their connection to the Taira, the Hōjō were also distant relatives of the imperial family. The Hōjō clan were in control of the province of Izu, which was in the east and quite far away from the center of power in Kyoto and the west.
