The aim of this research was undestanding the V (5 th ) National Assembly of the Process of Black Communities (PCN) from Communication in Culture and Social Constructionism. The above was possible through participation in the assembly, held in the city of Buenaventura from August 03th to 07th 2017, an accurate bibliographical documentation, participant observation and conducting in-depth interviews with three PCN activists. The results allow us to understand that the collective nature of the black communities has encouraged them to organize themselves politically, by adopting in a natural way, the characteristics of an assembly social movement based on collective construction, shared knowledge and decision-making by consensus. At the PCN assembly, as communicative and recognition figure, the notions of identity, memory, tradition and ancestry, territory and autonomy of the Black People in Colombia are articulated.
