[2] Before he was born, his father Yoritomo had Hōjō Tokimasa and his men carry stones to build the Dankazura on Wakamiya Ōji to pray for the child's safe delivery.

[4] From this relationship Hiki gained considerable influence when Yoriie became shōgun, incurring the hostility of Hōjō Tokimasa, who was instead close to Yoriie's younger brother Senman (future third shōgun Sanetomo), and who was in his turn trying to leverage that relationship for political advantage.

[2] On June 30, 1203, his remaining powers were formally taken from him and assumed by a council of 13 elders, headed by his grandfather Hōjō Tokimasa.

Hōjō Masako, Yoriie's mother and wife of the first shōgun Yoritomo, allegedly overheard the conversation.

Yoriie died in Shuzenji, a small town in what was later called Izu Province, assassinated by his grandfather Hōjō Tokimasa.

In 1219, Yoshinari murdered his uncle Sanetomo on the stairs leading to the shrine of Tsurugaoka Hachimangū in the shogunal capital of Kamakura, an act for which he was himself slain on the same day.
