The story of conflict and confrontation between Islam and the West has become daily news, but throughout the ages Muslims, Christians, and Jews have shared more than enmity and war; there is also a rich and textured history of coexistence that has all but disappeared from our collective memory. In this timely and revealing book, Zachary Karabell traces the legacy of tolerance and cooperation from the advent of Islam to the present day. In an extraordinary narrative spanning fourteen centuries, Karabell introduces us to the court of the caliphs in Baghdad, where scholars of various faiths engaged in spirited debate. He evokes the wonders of medieval Spain, where Jewish sages, Muslim philosophers, and Christian monks together deciphered the meaning of God and the universe. He offers a portrait of the Crusades that goes beyond the rivalry of Saladin and Richard the Lionheart, and shows how Christians and Muslims lived side by side. And he paints a vivid picture of religious autonomy in the Ottoman Empire.
