太上皇
Emperor Takakura is forced to retire and Emperor Antoku, Kiyomori's grandson, age 3, becomes the new Emperor. Retired Emperor Takakura angers the monks of Enryaku-ji by going to the Itsukushima Shrine instead of the Enryaku-ji. Minamoto no Yorimasa persuades Prince Mochihito, the second son of Retired Emperor Go-Shirakawa, to lead Minamoto forces against the Taira and become the Emperor. Prince Mochihito issues an anti-Taira call to arms. The open conflict between the Minamoto and the Taira is triggered by Kiyomori's son Taira no Munemori humiliating Minamoto no Yorimasa's son by taking away his horse and calling it by the owner's name.
