Minamoto no Yoshinaka
In 1158, Emperor Shirakawa II abdicated in favor of his son Prince Morihito (Emperor Nijō) and made the Hōjūjiden his home, entering cloistered rule. However, in 1183, he was informed by Minamoto no Yukiie that Minamoto no Yoshinaka intended to kidnap him, form a new government to the north, and use his possession of the cloistered emperor to justify his rule. The emperor informed the Minamoto brothers Yoshitsune and Noriyori in turn, and asked for their aid in stopping Yoshinaka. But they failed; Yoshinaka seized Kyoto in December 1183.
