Kamakura Bakufu and the Rise of Samurai

As regional clans gathered manpower and resources and struck alliances with each other, they formed a hierarchy centered around a toryo, or chief. This chief was typically a distant relative of the emperor and a lesser member of one of three noble families (the Fujiwara, Minamoto, or the Taira). Though originally sent to provincial areas for a fixed four year term as a magistrate, the toryo declined to return to the capital when their terms ended. Their sons inherited their positions and continued to lead the clans in putting down rebellions throughout Japan during the middle and later Heian.

Because of their rising military and economic power, the clans ultimately became a new force in the politics of the court. Their involvement in the Hogen Rebellion in the late Heian only consolidated their power and finally pit the rival Minamoto and the Taira against each other in the Heiji Rebellion of 1160. Emerging victorious, Taira no Kiyomori became an imperial advisor, the first warrior to attain such a position, and eventually seized control of the central government to establish the first samurai-dominated government and relegate the emperor to a mere figurehead. However, Taira clan was still very much aristocratic than later Minamoto. Instead of expanding or strengthening its military might, Taira clan had its women marry emperors and attempted to control through the emperor.

The Taira and the Minamoto once again clashed in 1180 beginning the Gempei War which ended in 1185. The victorious Minamoto no Yoritomo established the superiority of the samurai over aristocrats. In 1190 he visited Kyoto and in 1192 became Seii Taishogun, establishing the Kamakura Shogunate. Instead of basing its rule in Kyoto, he set up the Shogunate in the Kamakura, near his base of power. "Bakufu" means tent government, taken from the encampments the soldiers would live in, in accordance with the Bakufu's status as a military government.

Over time, powerful samurai clans became warrior nobility (buke) who were only nominally under court aristocracy. When samurai begun to adopt aristocratic customs like calligraphy, poetry and music, some court aristocrats also began to adopt samurai skills. In spite of various machinations and brief periods of rule by various emperors, the real power was in the hands of the shogun and samurai.
