The line comprises research turned to the study of inequalities in Africa and Americas in colonial and post-colonial contexts, with focus on the constitution of categories of exclusion and belongingness in the ambit of social, cultural, economic, political and ethnic-racial relations.  The development of this problematic implies the study of political cultures of individuals in situation of exclusion and the way they inform the perception of their places in social relations, and their social struggles for prerogatives and political rights in face of the institutional apparatuses of colonial states and nation-states.  For such, a bibliographic framework is mobilized that questions ethnocentric historiographic canons closely linked to the nation-state landmarks, emphasizing political dynamics constituted from the transit of people and ideas, particularly their different forms of collective identification.
