This book surveys the gripping history of the knights and relates their rise to power; their struggles against Prussian pagans; the series of wars against Poland and Lithuania; the clash with Alexander Nevsky's Russia; and the gradual stagnation of the Order in the fourteenth century. The book is replete with dramatic episodes - such as the battle on frozen Lake Peipus in 1242, or the disaster of Tannenberg - but focuses primarily on the year-after-year struggle to maintain power, fend off incursions and raiding bands, and to launch crusades against unbelieving foes. And it was the crusade, with knights demonstrating their valour, which chiefly characterised and breathed life into this militant, conquering Holy Order. The narrative charts the rise and fall of the Order, and, in an accessible and engaging style, throws light on a band of knights whose deeds and motives have long been misunderstood.
