This research investigates the postcolonial concept of colonialism and blasphemed racialization in Waiting for the Barbarians by John Maxwell Coetzee. It analyzes the fractured relation between Blacks and Whites during colonization. In fact, colonial era has favored the domination of Whites over Blacks resulting in the blasphemy of Africans’ race and culture. Coetzee intends to demonstrate that colonialism with its discourse and heritage has settled a clear distinction between both races. In so doing, this situation has occasioned Blacks’ misrepresentation in both their culture and race at the profit of Whites. Standing on postcolonial theory, the study reaches the point that John Maxwell Coetzee’s Waiting for the Barbarians is a narrative of colonialism and blasphemed racialization.
