Bushi formed new associations in what century?
Bushi interests were diverse, cutting across old power structures to form new associations in the tenth century. Mutual interests, family connections, and kinship were consolidated in military groups that became part of family administration. In time, large regional military families formed around members of the court aristocracy who had become prominent provincial figures. These military families gained prestige from connections to the imperial court and court-granted military titles and access to manpower. The Fujiwara family, Taira clan, and Minamoto clan were among the most prominent families supported by the new military class.
From 1854, the samurai army and the navy were modernized. A Naval training school was established in Nagasaki in 1855. Naval students were sent to study in Western naval schools for several years, starting a tradition of foreign-educated future leaders, such as Admiral Enomoto. French naval engineers were hired to build naval arsenals, such as Yokosuka and Nagasaki. By the end of the Tokugawa shogunate in 1867, the Japanese navy of the shogun already possessed eight western-style steam warships around the flagship Kaiyō Maru, which were used against pro-imperial forces during the Boshin war, under the command of Admiral Enomoto. A French Military Mission to Japan (1867) was established to help modernize the armies of the Bakufu.
