Ōe no Hiromoto

Ōe no Hiromoto (1148–1225), a Kyoto court noble, was a chief architect of the Kamakura shogunate. Summoned east by Minamoto no Yoritomo in 1184, he became the first bettō of the Kumonjo and, in 1191, of the Mandokoro.

In 1185 he urged Yoritomo to appoint jitō stewards and shugo governors. After Yoritomo's death he backed Hōjō Masako and in the Jōkyū War of 1221 pressed a march on Kyoto. His son Suemitsu founded the Mōri clan.
