Brazilian political history is marked by the reiteration of the figure of conciliation as a tool of political action and thought, pointing to the existence of important lines of continuity, underlying that concept, which can only be correctly unveiled from a long perspective duration. However, the exact definition of what is conciliation in Brazil still seems surrounded by doubts and mystifications, transposing between meanings of a cultural nature, related to the Brazilian social composition; of a psychological nature, linked to a supposed Brazilian national character; of an ideological nature, whether in relation to the class struggle or to national identity; to effectively political-economic meanings, linked to the need to integrate the political order, to the stratification of society, and to the division of power among its different classes. The present research proposes to firstly seek an eminently political conceptualization of conciliation, starting from the debate with different theoretical approaches. From there, through the bibliographical analysis of authors who have effectively interpreted conciliation as a political operator, we seek to identify the political macroprocesses revealed by such analytical tool, and the potentials and limitations they reveal for Brazilian social and political democratization.
