平治の乱
During the Heiji Rebellion (1160), the Seiwa Genji leader, Minamoto no Yoshitomo, died in battle. Taira no Kiyomori gained power in Kyoto forging alliances with retired emperors Shirakawa and Toba. Kiyomori sent Minamoto no Yoritomo (1147–1199), the third son of Yoshimoto, into exile. In 1180, Yoritomo organized a large-scale rebellion against the rule of the Taira (the Genpei War or "Taira-Minamoto"), culminated with the destruction of the Taira by the Minamoto clan and the subjugation of eastern Japan in five years. In 1192, Minamoto no Yoritomo received the title shogun and created the first bakufu based in Kamakura (Kanagawa Prefecture).
