Black radicalism is a field of academic inquiry and a body of intellectual and political thought that investigates the history, theory, and practice of radical resistance and liberation movements originating within or connected to the African diaspora. It is characterized by a fundamental critique of racial capitalism, white supremacy, colonialism, and other interlocking systems of oppression, often advocating for transformative societal change beyond reformist approaches, and offers alternative analytical frameworks and historical narratives centering Black agency and visions for liberation.
