This research seeks to analyze, though the use of Facebook, the conformation, structure and action of two platforms of movement - Paz a la Calle and the Student Movement, PAZiempre - that arose during the occasion of the plebiscite for the endorsement of the Peace Agreements between the colombian Government and the armed group, FARC. This monograph is framed within the social movements networks studies, since they share characteristics of the Arab Spring or the 15M, such as its spontaneous conformation through social networks, its local and global reach or the inclusion of diverse sectors.
