Minamoto no Sanetomo
After the death of Yoriie and Ichiman, Tokimasa installed Yoritomo's second son, Minamoto no Sanetomo, as the next "shōgun". Tokimasa began to chair the Mandokoro, while he and Ōe no Hiromoto exercised absolute power. In 1204, after the assassination of Yoriie, Hōjō Masako lost trust in her father, as she believed that he was behind the assassination of her son. It is also believed Tokimasa's wife, Hōjō no Maki died in late 1204.
