Hōjō Tokimasa

Hōjō Tokimasa (1138–1215) was an Izu magnate who guarded the exiled Minamoto no Yoritomo and gave him his daughter Masako. He backed Yoritomo's 1180 uprising against the Taira and helped found the Kamakura shogunate.

After Yoritomo's death he rose to power, and in 1203 became the first Hōjō shikken, crushing the Hiki family. In 1205 his plot to replace Shōgun Sanetomo failed; Masako and Yoshitoki forced him to take the tonsure and retire to Izu, where he died in 1215.
