While violence has long been a central object of analysis in Brazil, the concept of peace has remained marginal in both scholarly and policy debates. This chapter examines how peace is imagined, governed, and experienced in Brazil by mapping competing narratives across the political–institutional domain and the everyday perspectives of young people, a social group disproportionately affected by violence yet largely excluded from policy design. We identify three dominant approaches to peace: pacification, public security, and a more holistic, affective understanding articulated by youth. We argue that pacification and public security, which dominate the policy landscape, reproduce a narrow, security-centred conception of peace that echoes key logics of the liberal peace. In contrast, drawing on focus groups and written activities with young students in different Brazilian contexts, we show that youth articulate peace and violence in relational, emotional, and experiential terms, encompassing structural, symbolic, psychological, and affective dimensions. Rather than merely exposing policy gaps, these perspectives challenge dominant security frameworks by revealing the limits of approaches that disregard how peace is felt, imagined, and lived in everyday life. We contend that engaging seriously with the affective dimension is essential not only for understanding violence and peace in Brazil but also for rethinking violence prevention and peacebuilding more broadly.
