What is the relationship between the medieval crusades and the problems of the modern Middle East? Were the crusades the Christian equivalent of Muslim jihad? In this sweeping yet crisp history, Thomas F. Madden offers a brilliant and compelling narrative of the crusades and their contemporary relevance. Placing all of the major crusades within their social, economic, religious, and intellectual environments, Madden explores the uniquely medieval world that led untold thousands to leave their homes, families, and friends to march in Christ's name to distant lands. From Palestine and Europe's farthest reaches, each crusade is recounted in a clear, concise narrative. The author gives special attention as well to the crusades' effects on the Islamic world and the Christian Byzantine East.
