Student Movements and the Left in Argentina: The Era of University Expansion and Political Mobilization (1943–1976)

This article offers a comprehensive overview of the actions of leftist forces within the Argentine student movement between 1943 and 1976—a period shaped by the expansion of higher education, political instability, and the rise of new ideological actors. Drawing on existing literature and our own research, we examine how the left found fertile ground in universities to develop its political and ideological agenda, influenced by the legacy of university reform, the impact of Peronism, global contexts such as the Cold War and the Cuban Revolution, and increasing state repression. We highlight the movement's cycles of mobilization, radicalization, and retreat, in relation to shifting political landscapes, from early opposition to Peronist authoritarianism to eventual participation and marginalization under the third Peronist government. The article explores the diversity of leftist currents—communist, socialist, Guevarist, Maoist, Trotskyist—and their relationship with student organizations, as well as the limited but growing presence of women in this milieu. We analyze tensions between grassroots activism and institutional participation, between direct action and federated organizations, and strategic debates regarding the role of students in broader social transformation. This study seeks to deepen our understanding of a key actor in 20th-century Argentine political history.
