My presentation is twofold: First, I will consider the following approach: a) the studies of social movements stem from an approach that explores acquisition of rights in the context of their appearance; b) the radicalization of democracy involves democratization in the public and in the private sphere. Within this framework, special attention will be given to the analysis of the articulations among collective actions involved in the processes of struggles for the expansion of rights. The methodology used has two main steps: the study of the micro level of analysis (actors’ practices and discourses, social democratization) and the macro level (articulations, political radicalization).
Second, I will present a case study of collective actions, developed through eight years in Argentina that explores the articulations between popular movements. I suggest that as a wide range of social movements brought new interests to the public agenda it became possible to explore ways for the construction of new political identities and the expansion of citizenship.
