The effort to understand the distinctive characteristics and the historical and social bases of movements, groups, and parties identified as “new right” in Latin America and as “radical right” in Europe has generated intense debate. Given the diversity of perspectives, the author argues for the choice of the term “direitas radicais”, translated here as “radical right”, to emphasize the plurality and radicalization processes of movements, groups, and actors that have “strained” liberal democracy. The chapter presents a literature review focused on existing analyses on the topic, moving towards an exploration of studies on youth and political youth participation. From concepts such as subjectivation and political identities, the influence of post-structuralist studies and the analysis of neoliberalism as rationality is evidenced. Such studies suggest that identities can be interpreted as discursive formations related to mechanisms of power and the pursuit of institutional efficacy and representation. Overall, the chapter provides the references and concepts that guide the research.
