Kamakura period
The Kamakura period was the period during which the Kamakura shogunate ruled from the city of Kamakura, in the Kantô region.
The period is generally said to begin in 1185 with the Minamoto clan victory in the Genpei War, marking the end of the Taira clan's political control; others cite 1192 as marking the beginning of the Kamakura period, as this was the year in which the Kamakura shogunate was officially established, ending the period of Kyoto (aka Heian) being the sole center of authority. The period ends in 1333, with the fall of the Kamakura shogunate.
The Kamakura period marks a significant stage in the development of samurai rule. While the Taira clan held considerable power from the 1150s-1180s, they did so from within the Imperial court; the establishment of the Kamakura shogunate marks the first time that samurai rule, operating quite separately from the Imperial court, is asserted as a significant authority in itself. The Kamakura shogunate was never as strong as the Ashikaga or Tokugawa shogunates which succeeded it, however;
