Abstract EN:

This thesis takes as its object the process of political radicalization observed in young people from the working-class areas of Santiago de Chile. In order to understand this process, we have conducted an ethnographic field survey into the diverse practices of the political developed by subjects who are participants in direct action collectives. The field survey took place mostly during the period of student mobilization in 2011 and 2012, the most significant protest since the fall of the dictatorship in 1989. Based on the politicization of young people's experience, and through the interpretation of life histories, observations, and archive research, this study seeks to understand the motives underpinning radical involvement in which acts of political violence hold a central place an essential role. Organized in three parts, this study first investigates the role of history and memory as source of political radicalization within working-class groups. In a second time, a history of present tim< analyzed through an ethnography of protest events and of violence in situation sheds light oi the importance of the emotional aspects of protests and on the new practices of the politico (occupations of sites, direct democracy, counter-cultural practices, etc. ) in forms of radicc involvement founded on an autonomist vision of society. This thesis defends in a final part th' idea that individual experiences of the political have shifted towards community spaces. Thi creation of political, artistic and social collectives enables young people to recreate new kinds o normativity and forms of resistance, which are in turn taken up by other working-class actors.
