Abstract: For too long, questions of racism and colonialism have not been part of historical sociology’s understanding of modernity. Yet, a new generation of scholars has begun to address this, placing racism and empire at the center of their inquiries. This new generation looks to previously marginalized scholars for guidelines and inspiration. In line with this shift in historical sociology, this paper brings the work of W.E.B. Du Bois and other writers in the Black Radical Tradition to bear on longer-standing analytic and methodological debates: How do these authors allow us to think about theory-building and comparison? What is the goal of explanation? How should we approach archives and sources? Building on these insights, this paper explains how the work of Du Bois and the Black Radical Tradition provides a model for a new historical sociology, and a framework that allows us to see the connections between racism, colonialism, and modernity.
