武士形成における俘囚の役割 : 蕨手刀から日本刀への発展/国家と軍制の転換に関連させて <シンポジウム 社会構造の変容と傭兵>

At the war from the late 8th century to the early 9th century, a lot of Ezo (蝦夷) who was called Hushu, surrendered to Ritsuryo-koka (律令国家). Ritsuryo-koka transfered Hushu from Tohoku (東北) area to Rituryo-koka's territory, and turned them into Komin (公民) under the protection of Kokushi (国司). Komin had hostility to Hushu because Komin had to bear the cost of living for Hushu. In the 9th century, Kokushi exploited Hushu loyal to Kokushi as the military power, and oppressed the armed Komin who rose in revolt against Kokuga (国衙). Hushu was good at the tactics of horse riding and they used Warabiteto (a warped sword) . Hugoso (富豪層) took over the tactics from Fushu. In the late 9th century, Hushu rose in revolt against Kokushi to demand the usual allowance. So, the Government turned Hushu back to Tohoku area. From the late 9th century to the early 10th century, Taira-no-Takamoti (平高望), Fujiwara-no-Toshihito (藤原利仁), Fujiwara-no-Hidesato (藤原秀郷), were dispatched to suppress the revolt of Fugoso. In this battle, they improved on the Warabiteto to develop Kenukigatatati (毛抜形太刀) -Japanese sword-, which was able to innovate the tactics of horse riding. As the result, they became the earliest Bushi. Hushu played the mediate role for the birth of Bushi.
