  In Dusk of Dawn, Du Bois further develops his understanding of whiteness by interpreting racial oppression as, in Olson’s words, “a political problem of dark and white worlds arrayed against each other, with the white world determined to subordinate the dark one” (Olson, 22). Placing the conceptual opposition between white and dark (or non-white) worlds at the center of his analysis, Du Bois especially emphasizes the role whiteness plays in legitimizing the “domination of white Europe over black Africa and yellow Asia” (Du Bois, 1940, 48; see, also, Du Bois, 1940, 85–87; and Olson 26, 155, fn.60).
