 Kiyohara no Masahira, Iehira and Narihira, heads of branches of the family, created such a disturbance that Minamoto no Yoshiie, who had taken the formerly Abe post of Defender of the North, felt it necessary to interfere in the conflict.In 1083, he was appointed Governor of Mutsu, and arrived in the north to attempt to resolve the situation peaceably; he soon was forced to resort to gathering his own troops.After much fighting, the violence came to an end; Iehira and his uncle Kiyohara no Takahira had been killed, the other Kiyohara leaders surrendered.
