Over the course of the last 1400 years, Islam has grown from a small band of followers on the Arabian peninsula into a global religion of over a billion believers. How did this happen? The usual answer is that Islam spread by the sword-believers waged jihad against rival tribes and kingdoms and forced them to convert. Lamin Sanneh argues that this is far from the whole story. Beyond Jihad examines the origin and evolution of the African pacifist tradition in Islam, beginning with an inquiry into the faith's origins and expansion in North Africa and its transmission across trans-Saharan trade routes to West Africa. The book focuses on the ways in which, without jihad, the religion spread and took hold, and what that tells us about the nature of religious and social change.

At the heart of this process were clerics who used religious and legal scholarship to promote Islam. Once this clerical class emerged, it offered continuity and stability in the midst of political changes and cultural shifts, helping to inhibit the spread of radicalism, and subduing the urge to wage jihad. With its policy of religious and inter-ethnic accommodation, this pacifist tradition took Islam beyond traditional trade routes and kingdoms into remote districts of the Mali Empire, instilling a patient, Sufi-inspired, and jihad-negating impulse into religious life and practice. Islam was successful in Africa, Sanneh argues, not because of military might but because it was made African by Africans who adapted it to a variety of contexts.
