Revolución Libertadora.
The Revolución Libertadora was a 1955 Argentine military and civilian uprising that overthrew Juan Perón and removed the Justicialist regime from power, initiating a military-controlled interregnum that lasted until the 1958 return to civilian rule led by Arturo Frondizi. The coup involved coordinated actions by dissident elements of the Argentine Army, Argentine Navy, and Argentine Air Force, supported by sectors of the Catholic Church, the Radical Civic Union, and conservative industrialists, and produced deep political polarization between Peronist supporters and anti-Peronist forces.
Background and causes
In the early 1950s Argentina faced tensions among factions linked to Juan Perón, including conflicts with Eva Perón's legacy, confrontations with the Buenos Aires Catholic Church, and disputes with unions such as the CGT. Economic strains connected to international markets, relations with United Kingdom creditors, and trade negotiations with United States entities exacerbated divisions within the Argentine Armed Forces and industrial circles like the Argentine Industrial Union. Political crises surrounding media censorship involving outlets like La Prensa and La Nación, legal confrontations with the Supreme Court of Argentina, and clashes over constitutional prerogatives motivated conspiratorial plotting by military leaders associated with previous interventions including the 1930 Argentine coup d'état veterans and figures influenced by doctrines from the Chilean Army and Brazilian military. Anti-Peronist parties such as the Radical Civic Union and the Socialist Party aligned with dissident generals, while Peronism maintained mass support among workers organized in unions linked to the Justicialist Party.
April 1955 coup and military actions
A first major phase occurred in April 1955 when elements of the Argentine Navy and Air Force launched a failed bombardment of Plaza de Mayo targeting Casa Rosada in Buenos Aires, precipitating clashes with Peronist militias and loyalist army units. Notable actors included officers connected to prior uprisings such as Benjamín Menéndez and aviators sympathetic to anti-Peronist politics; the bombing intensified resistance from organizations like the CGT and drew condemnation from the Catholic Church hierarchy in Buenos Aires. The April events set the stage for the September offensive led by generals including Eduardo Lonardi and Pascual Pistarini, coordinated across garrisons in Córdoba, Rosario, and La Plata, and culminating in mass demonstrations where clashes occurred between Peronist supporters and insurgent units.
Interim military government and leaders
Following Perón's resignation and exile, a military junta assumed power proclaiming a transitional administration under figures such as Eduardo Lonardi and subsequently Pedro Eugenio Aramburu, with influential chiefs from the Argentine Army and Navy. Lonardi attempted a conciliatory approach toward Peronist sympathizers while Aramburu implemented a more hardline policy, purging loyalists from institutions such as the National University of La Plata and replacing officials tied to Juan Perón across ministries and provincial governments including Buenos Aires Province and Santa Fe Province. Political actors like the Radical Civic Union and Unión Cívica Radical Intransigente engaged with junta leaders, and diplomats from the United States Department of State and regional capitals such as Santiago (Chile) and Brasília monitored the transition.
Policies and repression
The junta enacted policies aimed at dismantling Peronism from public life: removing Justicialist Party insignia, outlawing Peronist political organizations, and censoring media outlets associated with Perón such as Radio El Mundo. Security measures included trials and purges targeting military officers accused of loyalty to Perón, internments of union leaders from the CGT, and interventions in cultural institutions including theaters and publishing houses in Buenos Aires. Measures against Peronist symbolism extended to renaming streets, altering curricula at universities like the University of Buenos Aires, and prohibiting Peronist rituals; repression included arrests, exile (notably of Perón to Paraguay and later Spain), and episodes of political violence that drew scrutiny from human rights advocates connected to organizations such as the Permanent Assembly for Human Rights (Argentina).
Political and social consequences
The overthrow reshaped Argentine party alignments: anti-Peronist coalitions coalesced around the Unión Cívica Radical and conservative federations, while Peronists were driven underground, forming clandestine networks and influencing labor actions in industrial centers such as Avellaneda and Lanús. Economic policy shifted as technocrats and industrialists negotiated with bankers in institutions like the Central Bank of the Argentine Republic and firms tied to Bunge y Born and Techint. Socially, the exclusion of Peronism intensified polarization within unions such as the CGT de los Argentinos and led to cycles of protest and repression that affected provinces including Tucumán and Mendoza Province, setting the context for later presidencies of Arturo Frondizi and Illia.
Legacy and historical interpretations
Historians and political scientists debate whether the coup represented a restoration of democratic norms or a conservative counterrevolution; scholars cite works comparing the episode to other Latin American interventions like the 1954 Guatemalan coup d'état and the 1964 Brazilian coup d'état. Interpretations by historians associated with institutions such as the National University of La Plata, the University of Buenos Aires Faculty of Social Sciences, and international centers in Madrid and Paris analyze the interplay of military culture, labor mobilization, and clerical politics. Cultural memory of the period persists in literature, film, and commemorations involving figures like Eva Perón and organizations such as the Justicialist Party, while legal debates over amnesty, political rehabilitation, and the role of the armed forces continue to influence Argentine constitutional discourse and transitional justice efforts.
