保元の乱
These two disturbances, known as the Hōgen Rebellion and Heiji Rebellion, ended in a Taira victory and the rule of the Cloistered Emperors Toba and Go-Shirakawa. Minamoto no Yoshitomo of the Minamoto clan was executed in 1160; all but three of his sons also executed, and his daughters sent to convents. Of the three sons that were spared, Minamoto no Yoshitsune and Minamoto no Noriyori were sent to monasteries, while his eldest son, Minamoto no Yoritomo, only 13 years old, was exiled to Tokimasa's domain of Izu.
