This article focuses on the intricate and developing nature of official politics and grassroots activism in post-revolutionary Mexico. It does so by tracing the trajectory of the Pentathlón Deportivo Militar Universitario, a right-wing youth movement that emerged in Mexico in 1938. By locating the group within both the international and domestic emergence of youth movements in the early twentieth century, the article shows how the study of Pentathlón's formation, objectives and later evolution can significantly enrich our understanding of an important phase in Mexico's post-revolutionary history. Within the context of right wing oppositional politics, analysis of the movement provides a fascinating insight into both the emerging Mexican state's ability to appropriate the radical impulses of the younger generation and the Pentathlón's willingness to accommodate such strategies in order to ensure its own survival.
