Miura Yoshimura
Miura Yoshimura (1168–1239) was head of the Miura clan and one of the most powerful gokenin of the Kamakura shogunate. After Yoritomo's death in 1199 he helped bring down Kajiwara Kagetoki, took part in destroying Hatakeyama Shigetada in 1205 and fought for the shogunate in the Jōkyū Disturbance of 1221.
He joined the Council of State under Hōjō Yasutoki in 1225 and in 1232 signed the Goseibai Shikimoku. He died suddenly late in 1239, the shogunate's ranking councillor after the Hōjō.
