Hired Swords: The Rise of Private Warrior Power in Early Japan

Tracing the evolution of state military institutions from the seventh through the twelfth centuries, this book challenges much of the received wisdom of Western scholarship on the origins and early development of warriors in Japan. This prelude to the rise of the samurai, who were to become the masters of Japan's medieval and early modern eras, was initiated when the imperial court turned for its police and military protection to hired swords--professional mercenaries largely drawn from the elites of provincial society.
