Commemorating the 150th anniversary of W. E. B. Du Bois's birth, the chapters in this book reflect on the local, national, and international significance of his remarkable life and legacy in relation to his specific commitments to socialism and democracy. Written with contemporary conditions in mind, such as the current political period of economic inequality, the debilitating reality of exploitative economic conditions, an expansive and invasive surveillance state, the grotesque injustice of the prison industrial complex, the ongoing crisis of police violence and the militarization of law enforcement, and a White House unashamedly spewing white supremacist, nationalist rhetoric in word and deed, this book collectively ponders how Du Bois's radicalism can shape and re-texture historical understanding and underscore a reflective urgency about the future. In this volume, scholars and activists undertake thoughtful and analytical explorations with regards to how Du Bois' commitments to socialism and democracy can inform current methodology and praxis. This book was originally published as a special issue of the journal Socialism and Democracy.
