Understanding social struggles for the right to health from generation to generation is the main objective of this investigation. It seeks to reflect on what extent the generational belonging of the actors presents heuristic potential in the analysis of contexts, historical trajectory, and forms of collective action of social movements. In an exploratory and qualitative approach, generation is considered as an explanatory possibility of some sociologically reflected concrete political phenomena and events: questions related to languages, interpretative frameworks, action repertoires, political identities, or use of technologies, for instance, make up the analysis under the perspective of generational coexistence in the collective action of social movements and can elucidate the formation of hierarchies, disputes, consensus, continuities, ruptures and agendas in the historicity of a social struggle. Both in retrospect and prospective sense, being recognized or recognizing oneself as part of a generation is the same as interpreting and situating oneself in the social and political events experienced at a given time and in a given culture; it is to transpose the set of individual experiences into a common generational experience. As an empirical observation, the forms of collective action driven by actors in the field of health are adopted during the period from the 1980s of the 20th century to the first two decades of the 21st century. The methods and techniques employed were: documentary research and semi-structured interviews with key actors, identified as representatives of different political generations dedicated to the struggle for the right to health.
