This book explores the transformative role of Uthman bin Fodio in the reformation of Nigerian society, tracing his da?wah (religious calling) from its earliest expressions to the establishment of the Sokoto Caliphate in the 19th century. While much has been written about his legacy, this study uniquely focuses on the initial motivations, methods, and communal strategies he employed, often overlooked in mainstream scholarship. Building upon the foundational theory of societal change (?umr?n) by Ibn Khaldun, the work examines the intellectual and spiritual interplay between the Maghribi thinker and the West African reformer. It argues that Ibn Khalduns cyclical theory of social development deeply informed Uthman bin Fodio?s vision, tactics, and success in transitioning society from a traditional to an Islamic governance model. Engaging both classical Islamic thought and historical sociology, this book fills a critical gap in understanding the ideological roots and methodological strategies behind one of the most significant Islamic reform movements in Sub-Saharan Africa. It will be a vital resource for students, historians, Islamic scholars, and anyone interested in the intersection of religion, society, and political change in Africa.
