In , award-winning historian Brian A. Catlos rewrites the history of Islamic Spain from the ground up, evoking the cultural splendor of al-Andalus, while offering an authoritative new interpretation of the forces that shaped it. Prior accounts have portrayed Islamic Spain as a paradise of enlightened tolerance or the site where civilizations clashed. Catlos taps a wide array of primary sources to paint a more complex portrait, showing how Muslims, Christians, and Jews together built a sophisticated civilization that transformed the Western world, even as they waged relentless war against each other and their coreligionists. Religion was often the language of conflict, but seldom its cause -- a lesson we would do well to learn in our own time.
