This is an accessible introduction to the most violent, turbulent, cruel and exciting chapter in Japanese history. In 1467 the Onin War ushered in a period of unparalleled conflict and rivalry in Japan that came to be called the Age of Warring States. In this book, Stephen Turnbull offers a masterly exposition of the wars, explaining what led to Japan's disintegration into rival domains after more than a century of relative peace; the years of fighting that followed; and the period of gradual fusion when the daimyo (great names) strove to reunite Japan under a new Shogun. Peace returned to Japan with the end of the Osaka War in 1615. Turnbull draws on his latest research to include new material for this updated edition, covering samurai acting as mercenaries, the expeditions to Korea, Taiwan and Okinawa, and the little-known campaigns against the Ainu of Hokkaido, to present a richer picture of an age when conflicts were spread far more widely than was hitherto realised. This updated and revised edition provides a concise overview of Japan's turbulent Age of Warring States.
