Hōjō Yoshitoki
Hōjō Yoshitoki (1163–1224), second Hōjō shikken, was a son of Tokimasa and younger brother of Masako. In 1203 he helped destroy the Hiki clan and enthrone Sanetomo; in 1205 he and Masako ousted their father, making him the shogunate's strongest man.
After Sanetomo's assassination in 1219 he ruled outright. When Retired Emperor Go-Toba ordered his overthrow in 1221, bakufu forces took Kyoto in the Jōkyū War and exiled three retired emperors. Yoshitoki died suddenly in 1224.
