To reflect on post-colonialism in relation to Afro-Brazilian studies is to situate a very specific historical context of decolonization. In this talk, I will approach three moments of this process of decoloniality, as different moments of African- Brazilian struggles, and as moments of reception of new ideas circulating internationally. The first one was the concept of internal colonialism as a legacy of the American civil rights movement. The second one, stretching to the 1980s, and advancing studies in India, under the influence of British Marxist historiography (history from below).the current days, was Fanon's reception by the new generation of Brazilian black activists. Finally I will concentrate my attention on the writing of a new Brazilian historiography of slavery and its implicit dialog with the Black movement, an almost perfect match of what did the subaltern.
