Heiji Rebellion
is a Japanese war epic ("gunki monogatari") detailing the events of the Heiji Rebellion of 1159–1160, in which samurai clan head Minamoto no Yoshitomo attacked and besieged Kyoto, as part of an Imperial succession dispute, in which he was opposed by Taira no Kiyomori, head of the Taira clan. The Tale, like most "monogatari", exists in three main forms: written, oral, and painted.
