Exploring the development and structuring of African nationalist sentiment, the intellectual and sociological foundations of African nationalism, and the origins and social and cultural identities of the participants who helped form the anticolonial movements in the Portuguese colonial empire, Origins of African Nationalism captures the revolutionary energy of a generation. Named one of Africa's hundred best books of the twentieth century, this innovative study traces the emergence of African nationalism starting at the end of the nineteenth century and illuminates how nationalists from across the Portuguese empire were brought together in subsequent decades in a unified struggle that would lead to the overthrow of colonial rule after the Second World War. Mário Pinto de Andrade's insights are now available to English readers for the first time.
