How have the crusades contributed to Islamist rage and terrorism today? Were the crusades the Christian equivalent of modern jihad? In this sweeping yet crisp history, Thomas Madden offers a brilliant and compelling narrative of the crusades and their contemporary relevance. Placing all the major crusades within their medieval social, economic, religious, and intellectual environments, Madden explores the uniquely medieval world that led untold thousands to leave their homes, family, and friends to march in Christs name to distant lands. From Palestine and Europes farthest reaches, each crusade is recounted in clear, concise narrative. The author gives special attention as well to the crusades effects on the Islamic world and the Christian Byzantine East.
