The overarching objective of this special issue is to gain a more in-depth understanding of the various forms of social and political participation of young people in the Maghreb-Algeria, Morocco, and Tunisiafrom the period after the wave of dissent of 2011 (termed 'The Arab Spring' in the media) dissipated up to the revolt that has been underway in Algeria since February 2019. More specifically, it aims to answer three main questions that, in turn, correspond to three levels of analysis of political activism. On a micro level, this special issue first interrogates how the participation of young people in the protest movements of 2011 was forged and what influence this experience has had on the construction of their individuality. Secondly, and focusing on collective action through the groups that lead it, the issues asks how these young people, socialised in an authoritarian environment, mobilised and formalised their activism. Finally, it asks what influence the various forms of managing pluralism, as well as social and political dissent, has had on the ways in which these young people expressed their dissatisfaction. This introduction, provides an overview of the various contributions to the dossier and situates them in the main sociological issues at hand.
