Heiji Rebellion (平治の乱) - S1.E26

In 1159, Yoshitomo finally decides to join hands with Nobuyori and rises in revolt against Shinzei--the Heiji Rebellion. Yoshitomo and Nobuyori place Emperor Nijo (Emperor Go-Shirakawa's son who has ascended the throne) and the former Emperor Go-Shirakawa under confinement, and set fire to the Imperial Palace. Kiyomori, who learns of the rebellion while heading for Kumano, immediately returns to Kyoto. Although Shinzei tries to hide in the mountain, he is found by his pursuers and commits suicide.
