This dissertation understands that conflict is inherent in the social order, always being an analytical possibility of the constitutive tensions of each society or social group. Thus, starting from the situational analysis of the cut of funds made by the city hall in the management Marcelo Crivella for realization of the parades of the samba schools of the carioca carnival; I intend to describe the dynamics of the process between these community and recreational associations and the powers with which they relate. The samba schools conquered the hegemony of folly in the carnival of Rio de Janeiro throughout the 20th century through negotiations and mediations, especially the public power and the press, to overcome other existing forms of carnival organization. They benefited from a political and social process of building a national identity where the samba fulfilled a prominent integrating role. Their ritual-competitive parades have become a major tourist and commercial spectacle. Today these associations are represented by an entity marked by the performance of the summit of the game of the beast of the state of Rio de Janeiro that organizes the party in co-management with the municipal public power. Thus, the parade of the samba schools of Rio de Janeiro is also a space for mediation between two forms of power: a constitutional and republican power and a power linked to the activity of the criminal contravention represented by LIESA. The city government, which is responsible for the parades, was an important partner for the consolidation of the parades and their transformation into an internationally recognized spectacle. The cut of funds for its realization, executed by a mayor who had the support of the LIESA in the elections, is a privileged opportunity to elucidate the relation between culture and politics in the city of Rio de Janeiro through the phenomenon of the samba schools.
