This paper is a written dialogue among four activists from the Emancipa Popular Education Movement in Brazil, following the principles of Freirean pedagogy as a "circle of culture." It delves into how "popular knowledge can be experienced as popular power," narrating the history, struggles, and strategies employed by the Emancipa movement in their pursuit of democratizing Brazilian universities. The discussion is set within the context of Latin American structural inequalities and the issue of educational exclusion in Brazil. It emphasizes the vital role of contesting culture and knowledge as part of the movement's fight against social injustices perpetuated by peripheral capitalism, including racist violence and gender oppression. The paper adopts emancipatory pedagogy as the method to empower and mobilize grassroots efforts in this transformative endeavour.
