The objective is to outline ideological profiles and how they are consolidated, (re)creating and legitimizing social inequalities and exclusions of all kinds. In particular, it is of interest to trace the way in which the «other» is constructed, the one to which it opposes itself in search of legitimation. Addressing the discussion on ethnic-racial and cultural issues and the construction of identities from them, this line is complemented by research on Indigenous Policies, Ethnicities, Gender, and Legal Pluralisms.
