While social movement research employs “tactical repertoire” to emphasize protest tactics directed at the state, literature on youth activism globally indicates that young people do politics outside the realm of formal political spheres. Youth activism on body politics in Latin America offers evidence that enhances conceptual tools intended for understanding how young people make claims and towards whom they make them. This paper takes young activists’ strategies as its point of departure through a study that explored how young people perceived their activism to advance sexual health in Ecuador and Peru. Young activists employed a range of interconnected strategies that went beyond protests directed at the state, including responding to adult allies, carrying out social advocacy among youth, building organizations, carrying out political advocacy and developing themselves as activists. Strategies were shaped by the degree to which young activists negotiated alternative notions of ‘youth’ with different actors.
