↑"...not only was the Heian system of imperial-aristocratic rule still vigorous during the twelfth century, but also it remained the essential framework within which the bakufu, during its lifetime, was obliged to operate. In this sense, the Heian pattern of government survived into the fourteenth century - to be destroyed with the Kama-kura bakufu rather than by it." Warrior Rule in Japan, page 1. Cambridge University Press.
↑"...warriors had come to exercise a domi-
nant share of the total volume of local government, but even after
two hundred years they remained politically immature. The most
exalted warriors were still only middle-level figures in hierarchies
dominated by courtiers and religious institutions in and near the
capital. The bakufu's founding in the 1180s thus represented an
initial breakthrough to power on the part of elite fighting men"
