Hōjō Tokimasa
His new allegiance to his wife's family and her dislike of her brothers-in-law, as well as an internal power struggle brought up by the three brothers, eventually resulted in the arrest and execution of Yoshitsune and Noriyori. Yoritomo even created new titles, such as shugo and jitō, which Hōjō Tokimasa received approval from Cloistered Emperor Go-Shirakawa in Kyoto. The capital was not moved to Kyoto, but remained away from the court in Kamakura.
