This dossier proposes to explore the uprising as a critical event provoking unprecedented processes of political subjectivation and opening the field of action and influence to subjects who had been kept on the margins of the construction of history. This introduction begins by describing the social uprising that occurred in Chile in 2019, the largest cycle of protests since the end of the Pinochet era. It then discusses the notions of critical event and political subjectivation and the methods followed with the research participants. Finally, drawing on the three essays, the introduction identifies four dimensions of the critical nature of this event and its entanglements with the production of political subjectivation, namely, time, oikos, police, and politics.
