In most of this period, the shoguns were the "de facto" rulers of the country; although nominally they were appointed by the Emperor as a ceremonial formality.

Nevertheless, an unusual situation occurred in the Kamakura period (11991333) upon the death of the first shogun, whereby the Hj clan's hereditary titles of "shikken" (1199-1256) and "tokus" (12561333) monopolized the shogunate as dictatorial positions, collectively known as the .
