北条時政
Masako heard rumors that Tokimasa was planning to execute Sanetomo and replace him with one of his allies, so Masako and Yoshitoki immediately ordered Tokimasa to step down and go into priesthood or they would rebel. Hōjō Tokimasa abdicated in 1205, and was sent off to a monastery in Kamakura, where he shaved his head and became a monk, dying in 1215.
