Abstract
In this article, we approach how various student associations that have emerged in recent years in Spain have been activating the socio-political participation of young people in the sphere of civic constitutionalism. Using qualitative interviews and participant observation, we document the diversity and territorial presence of these associations. We delve into their ideology and the cluster of activities and action strategies they employ. One notable aspect is their ability to deploy frames of meaning that compete with and/or complement other forms of activism, discourses, and political demands common among alternative social movements and those advocating for social justice. For example, how they understand democratic institutions and university coexistence, the role of educative institutions in their formative development, or issues of strong public controversy.
