The article aims to understand the meanings that the Brazilian document National Common Curricular Base (BNCC) tries to fix for the significant diversity in the curricular component of History. The text analyzes the document as a discursive mechanism that operates within a regime of truth at the service of the search for hegemony in the educational and social fields. The qualitative study, of documentary and bibliographic character, approached the fundamentals of the concepts that consolidate the BNCC. The considerations point out that the hybridization of significant diversity hides meanings linked to a project based on the perspective of a functional interculturality, which advocates the depoliticization of the educational process through the subordination of knowledge itself (the contents of History and the theme of diversity) to knowledge in order to do something (the discourse of competence).
