This dissertation aims to investigate violence in Maré Complex of favelas considering its relationship with Escola Municipal da Paz. It focuses on this school as an epicenter of discussion and tries to analyze how objects or things, in their agency, assert themselves as markers of peace or violence states, through the engagement of the perception of the subjects involved in this context. In order to examine network actions, we take into consideration how things and people evolve in this relationship. In the first part of the work, there is a discussion about the journey of favelas creation and their affirmation inside the urban space. Then, it focuses on the multiple powers of the Maré complex. It also discusses how the experiences of the researcher dialogue with the history of that territory.

We also have a presentation of Escola Municipal da Pazin this chapter. The third chapter discusses the notion of violence, with subsequent ethnographic research of things, pointing out the knowledge of violence, which is done and redone in the flow of things and people.
