This analytical introduction assesses contrasting definitions of black nationalism in America, thereby providing an overview of its development and varied manifestations across two centuries. Its aim is to evaluate historiographical debates and synthesize a broad range of scholarship, much of it published since the beginning of the new millennium. However, unlike some of that work, this book offers a critical perspective that avoids advocacy or condemnation of black nationalism by examining major black nationalist thinkers, leaders and organizations as well as discussing some lesser-known groups and figures, the nature of black nationalism's appeal and the position of women in and their contributions to black nationalism.
