This book examines the radicalisation of political discourse in Latin America, where historical grievances and media ecosystems shape social imaginaries and political practices. It is organised into four parts. Part I: Introduction sets the research context. Part II: Critical Apparatus provides the analytical foundation, addressing the theologisation of politics, hate discourses, and subjectivation processes. Part III: Case Studies offers detailed analyses of Argentina’s libertarian populism and anti-statist narratives, Peru’s far-right manipulation of historical memory and religious rhetoric, Chile’s post-social uprising dynamics, marked by nationalist resurgence and institutional conservatism, and Brazil’s denialism and media spectacle during the Bolsonaro era. Finally, Part IV: Epilogue reflects on the broader implications for discourse analysis and sociopolitical inquiry. This book dissects the linguistic mechanisms behind these phenomena and poses critical questions for further research. Its interdisciplinary approach will appeal to experts in sociology, political science, and discourse studies, fostering a deeper understanding of Latin America’s complex sociopolitical landscape.
