How the competition for young recruits is creating rivalries among Islamists today Today, two-thirds of all Arab Muslims are under the age of thirty. Young Islam takes readers inside the evolving competition for their support—a competition not simply between Islamism and the secular world, but between different and often conflicting visions of Islam itself. Drawing on extensive ethnographic research among rank-and-file activists in Morocco, Avi Spiegel shows how Islamist movements are encountering opposition from an unexpected source—each other. In vivid and compelling detail, he describes the conflicts that arise as Islamist groups vie with one another for new recruits, and the unprecedented fragmentation that occurs as members wrangle over a shared urbanized base. Looking carefully at how political Islam is lived, expressed, and understood by young people, Spiegel moves beyond the top-down focus of current research. Instead, he makes the compelling case that Islamist actors are shaped more by their relationships to each other than by their relationships to the state or even to religious ideology. By focusing not only on the texts of aging elites but also on the voices of diverse and sophisticated Muslim youths, Spiegel exposes the shifting and contested nature of Islamist movements today—movements that are being reimagined from the bottom up by young Islam. The first book to shed light on this new and uncharted era of Islamist pluralism in the Middle East and North Africa, Young Islam uncovers the rivalries that are redefining the next generation of political Islam.
