Since 2011, a series of citizen mobilizations have emerged in Romania, from local replicas of the ‘Occupy’ movement to the 2017 and 2018 mass protests against corruption. In this article, we develop three arguments for a better understanding of the successive waves of protests that have shaken the Romanian social and political landscape since 2011. First, while each protest has a specific claim and target, the forms of commitments, repertoire of actions and relationship to politics point to clear continuities between protest events that should be analyzed as part of the same cycle of protests. Second, while some analyses have emphasized the specificities of the Romanian context, we maintain that the actors and dynamics of this cycle of protest are simultaneously deeply national, embedded in the mutations of Eastern European civil society, and in resonance with the post-2011 global wave of movements. Third, while it is indispensable to analyze these citizen mobilizations as a whole, it is equally important to understand that they result from the convergence of diverse activist cultures, from left-wing autonomist activists to right-wing citizens and even nationalist militants. Each of these activist cultures has its own logic of action and its vision of democracy and of politics.
