How can religion transform a society? This book investigates how a medieval Islamic movement harnessed Qur'anic visions of utopia to construct one of the most brilliant and long-lasting empires in Islamic history. The Fatimids' apocalyptic vision of their central place in an imminent utopia played a critical role in transfiguring the intellectual and political terrains of North Africa in the early 10th century. Yet the realities that they faced on the ground often challenged their status as the custodians of a pristine Islam at the end of time. This is the first volume in our new series, Edinburgh Studies in Islamic Apocalypticism and Eschatology, edited by David Cook and Christian Lange.
