This article aims to understand how manifestations of civic engagement emerge in young people from vulnerable contexts and how edu-communicative processes could be useful in understanding how they connect with civic engagement. These results stem from the case study of a Horizon 2020 project that took place from January to June 2022 with young people aged 16-18 from an educational association in the Raval neighbourhood in Barcelona. It involved 32 workshops in which we applied participatory audiovisual methodology and ethnographic work based on participant and non-participant observation. The results identified that the educommunicative process allowed young people to develop a collective outlook and a social identity that favoured awakening their interest, expressing opinions and reacting to the problems of their context. Thus, we conclude that these processes can contribute to guaranteeing the rights of young people to participate in civic and political life with a diverse perspective that pays attention to their own motivations and ways of expressing themselves.
