源氏
Believing that Taira no Kiyomori was causing suffering, Mochihito supported the Minamoto clan in their conflict against the Taira. At the same time, Minamoto no Yorimasa led the Minamoto clan in supporting Mochihito's bid for the Imperial Throne. In May 1180, Yorimasa sent out a call to other Minamoto leaders, and to the monasteries (Enryakuji, Miidera and others) that Kiyomori had offended; he asked for aid against the Taira, in the name of Prince Mochihito.
