With the advent of the coronavirus pandemic in Brazil, the populations of Brazilian peripheries and slums have become the focus of greatest social risk, due to the historical issue of social inequalities that conformed these territories. The activism of the social forces that compund civil society, in this context, has assumed the centrality of the social protection work of the most socially vulnerable population, in the vacuum left by public policies. In this study, the experience of a campaign conducted by Redes da Maré, a non-governmental organization originated by the trajectory of social struggles of the residents of the favelas under the neighborhood of Maré, is being analyzed as a decisive example for the survival of local residents and promotion of rights, due to the mobilization of a wide range of actors and consolidating a solidary and potent network capable of benefiting more than 50 thousand people directly in 2020.
