The term Black Consciousness stems from American educator W. E. B. Du Bois's evaluation of the double consciousness of American blacks, being taught what they feel inside to be lies about the weakness and cowardice of their race. Du Bois echoed Civil War era black nationalist Martin Delany's insistence that black people take pride in their blackness as an important step in their personal liberation. This line of thought was also reflected in the Pan-Africanist, Marcus Garvey, as well as Harlem Renaissance philosopher Alain Locke and in the salons of the sisters, Paulette and Jane Nardal in Paris. Biko's understanding of these thinkers was further shaped through the lens of postcolonial thinkers such as Frantz Fanon, Léopold Senghor, and Aimé Césaire. Biko reflects the concern for the existential struggle of the black person as a human being, dignified and proud of his blackness, in spite of the oppression of colonialism. The aim of this global movement of black thinkers was to build black consciousness and African consciousness, which they felt had been suppressed under colonialism.
