5War played a central part in the history of Japan. Warring clans controlled much of the country. The wars were usually about land, the struggle for control of which eventually gave rise to perhaps the most formidable warriors of all time: the Samurai. Ancient Yayoi warriors developed weapons, armour and a code during the ensuing centuries that became the centrepiece for the Japanese Samurai. Anthony Bryant chronicles the history, arms and armour of these truly lite warriors, from the rise of the Yayoi through the Genpei War (1180-1185) between the Minamoto and Taira clans, to the Mongol invasions of the 13th century.
