Although they existed for only three years, the Popular Cultural Centers marked the history of popular movements and engaged art in Brazil. Initially an organ linked to the National Union of Students, the CPC of Rio de Janeiro created a series of cells throughout the country, linking up with different student, union and popular entities, fostering alliances between artists, students and manual workers and intellectuals of the countryside and the city. Its objective was to structure an artistic production that would serve the construction of socialism in Brazil.
