The aim of this paper is to present Du Bois' concept of double consciousness to show how Du Bois managed to find a solution to blacks' psychological fragmentation in the American racist society. Accurately, Du Bois explained what happened to blacks in America at the hands of whites, he talked about the issues of blacks like racism, discrimination, injustice, humiliation, oppression and slavery, moreover he showed their psychological suffering and their mental fragmentation because of this oppression, but at the end he found a solution to their psychological fragmentation by explaining the concept of double consciousness to the elite and educated persons. Du Bois explained the dilemma of having two identities in one body and how blacks managed to reconcile the two cultures that compose their identity. This paper also explains how he moved African Americans' crisis from the American history and placed it at the center of a global history. Du Bois introduced a term of Double consciousness in a distinctive and original way to name a largely unremarkable phenomenon. He was occupied throughout his life with an attempt to understand both the socio-historic conditions which face black folks in the twentieth century American society, and the impacts of these conditions on the consciousness or the inner world of the human beings who subject to these psychological crises. This concept gives a name to what so many African-Americans feel but previously could not express due to a lack of words to accurately describe their pain.
