The shicks (執 権) were the shogun rains during the Kamakura Shogunate in Japan. The post was monopolized by the Hojo clan. In Japanese history, this system only existed between 1203 and 1333.
Hojo Tokimasa, the father-in-law of the first Kamakura shogun Minamoto no Yoritomo (1147-1199), became the first shark in 1203, ruling for his grandson Shogun Minamoto No Yoriie. The shicks were chairman of the mandokoro, the legislative and executive power, and in principle held power. In 1203, Tokiasa replaced the Shogun Minamoto No Yoriie by his brother Sanetomo, becoming the de facto ruler of the Shogunate (Japan).
The son of Tokimasa, Yoshitoki, reinforced the position by adding the post of the head of the Samurai-dokoro (vassall) doc after turning off the powerful Wada clan who had the post until then had dominated. The shaking thus became the highest post, and the shoguns were only shrubs of shicks in practice. In 1224, the son of Yoshitoki, Hojo Yasutoki, introduced the position of rensho (co-draftsman) as assistant of the regent.
During the first period, the position of shaking was occupied by Tokuso, the head of the Hojo clan, until Hojo Tokiyori split the two posts in 1256. He appointed Hojo Nagatoki to shake while his young son Tokimune followed him as tokuso. The power was now effectively moved from shaking to tokuso. List of shicks Also see
