Kamakura bakufu warrior-government system

Timeline

1. 1185–1192Kamakura · JapanAfter the Battle of Dan-no-ura, Minamoto no Yoritomo established his position as warrior leader, set up bakufu institutions at Kamakura, and based them on rewards to gokenin and military mobilization, gradually moving beyond a mere military alliance toward a permanent governmental system.
2. c. 1192–1221Japanese archipelago · JapanAfter Yoritomo was appointed sei-i taishōgun, the bakufu brought local military security and estate corvée management into the warrior system by appointing shugo and jitō, forming a multi-layered power structure of court–bakufu–lords.
3. 1203–1297Kamakura · JapanThe Hōjō clan held real power in the bakufu under the title of shikken, perfecting the hyōjōshū, gokenin solidarity and the gion–hōkō relationship of favor and service, and strengthening military mobilization before and after the Mongol invasions, making the Kamakura warrior system a stable framework of rule over Japan for nearly a century and a half.
4. 1331–1333Kamakura · JapanUnder Emperor Go-Daigo's movement to overthrow the bakufu and attacks by Ashikaga Takauji and other forces, the Hōjō clan perished at Kamakura and the Kamakura bakufu system ended, but its warrior-political model of shogun–gokenin–local power-sharing was inherited by successor regimes such as the Muromachi shogunate.
