This paper examines the transformations in actor-network collective action in the Process of Black Communities —pcn—, which were developed as a consequence of the armed conflict worsening in the Pacific region —specifically on the collective lands in the municipalities of Buenaventura and Suárez (Southwestern Colombia)— in the last ten years. Information was gathered through semi-structured interviews, observation records, analysis of audio/text documents on the organizations’ claims and communiqués, and the drafting of aggregated data on displacement and conflictual facts in the region. Findings show a significant up surging of conflict within the period, in the face of which PCN’s coalitions with local and global actors have come both to neutralize and make visible armed actors’ actions against populations, and to reorient collective action, introducing innovations in the repertoires of action and setting new goals for this actor-network in the region.
