Abstract: This article deals with the issue of Pan Africanism from America, via Europe, until Africa. Our goal is to show how the challenges of Pan-Africanism started in America with activities of Sylvester W.E.B Dubois until Kwame Nkrumah in Africa. Despite theclaimings for their cultural identities, their origins, and different activities of Sylvester W.E.B Dubois, Afro-American remain under the white men domination, not only in the socio-cultural field, but also in the socio-political even economic as well. So more than 60 century ago, the whole cultural, socio-politics, even the economic life in America was totally belonging to the white men. So, through socio historical approach, we have noticed that the ideas of the African Unity resulted from the different activities of Pan-Africanism by Silvester W.E.B Dubois in America, via Europ and finally in Africa with Kwame Nkrumah.
Key Words: Pan-Africanism, Afro- American, ideas, movement, Phases, Periods.
