Shikken

The nihongo|Shikken|執権 was the regent for the shogun in the Kamakura shogunate in Japan. The post was monopolized by the Hōjō clan, and this system only existed once in Japanese history, between 1203 and 1333. Note this is totally different that an Imperial Regent or Kampaku (also Sessho).

Hōjō Tokimasa, who was the father-in-law of the first shogun Minamoto no Yoritomo, became "shikken" for the first time in 1203. The "shikken" was the chief of the "mandokoro" at that time. Replacing the second shogun Minamoto no Yoriie with Sanetomo, he became the de facto ruler of the shogunate.

Tokimasa's son Yoshitoki strengthened the post by integrating it with the chief of Samurai-dokoro after annihilating the powerful Wada clan, who had dominated the position. The "shikken" became the highest post, controlling puppet shoguns in practice. In 1224 Yoshitoki's son Hōjō Yasutoki set up the position of "rensho" (cosigner) as assistant regent.

At first the post of "shikken" was occupied by the "tokusō", the head of the Hōjō clan, but Hōjō Tokiyori separated the two posts. He installed Hōjō Nagatoki as "shikken" while he made his son Tokimune succeed as "tokusō". Effective power was moved from "shikken" to "tokusō".
