Revolución Libertadora (1955) The Revolución Libertadora (1955) was a military and civilian uprising that deposed Juan Perón and ended his second presidential term, inaugurating a period of military rule and political proscription that reshaped Argentina's mid‑20th century trajectory. The insurrection combined naval bombardment, air strikes, and urban uprisings in Buenos Aires with subsequent consolidation by a junta, provoking debates among historians, journalists, and political scientists about legitimacy, repression, and reform.

Background

By 1955 Juan Perón had clashed with institutions such as the Catholic Church, Confederación General del Trabajo (CGT), and sections of the Argentine Armed Forces, while facing opposition from parties like the Radical Civic Union and the National Democratic Party. Perón's alignment with labor leaders including José Rucci and policies invoking the Justicialist Party platform generated support among industrial workers in Greater Buenos Aires and antagonism from business elites linked to Banco Nación and industrial conglomerates tied to Carlos Llerena. Internationally, Perón's tensions with the United States and relations with Spain and Italy intersected with Cold War dynamics involving Harry S. Truman's and Dwight D. Eisenhower's administrations. Cultural conflicts over figures like Eva Perón and institutions such as Universidad de Buenos Aires intensified public polarization, while economic indicators influenced by the Trigo Agreement and agricultural exports to United Kingdom markets contributed to elite discontent.

Coup and Fall of Perón

In June and September 1955 naval officers from units centered in Puerto Belgrano and aviators from bases such as Morón launched operations against Perón, culminating in the Bombing of Plaza de Mayo and uprisings in La Plata and other cities. Key conspirators included officers associated with Grupo de Oficiales Unidos and figures who later emerged in the junta, while Perón relied on loyalist units and supporters in the CGT and loyalist militias. The violent confrontation, including the Plaza de Mayo bombing and street battles in Recoleta and San Telmo, led to heavy civilian casualties, eroded Perón's power base, and prompted Juan Perón to seek exile, after contacts with envoys from Brazil and offers mediated by diplomats linked to Pope Pius XII and representatives of Spain.

Interim Military Government

Following Perón's departure a provisional government formed under generals including Eduardo Lonardi and later Pedro Eugenio Aramburu, who established the Revolución Libertadora junta that annulled aspects of Perón's administration, dissolved the Justicialist Party, and instituted purges in institutions like the Judiciary and Universidad de La Plata. The junta negotiated with political leaders from the Radical Civic Union, the Socialist Party (Argentina), and conservatives affiliated with the National Democratic Party while confronting factions within the Argentine Army and oppositionists loyal to Perón. Military decrees suspended the 1951 Constitution's application in parts, and the junta organized trials and administrative interventions affecting officials from ministries such as the Ministry of Labor.

Political and Social Repression

The junta carried out proscription of Peronism, incarceration and exile of prominent Peronists including trade unionists and cultural figures associated with Eva Perón's circuit, and censorship imposed upon newspapers like Crítica and radio stations tied to the Fundación Eva Perón. Arrests targeted leaders with links to organizations such as the Confederación General del Trabajo (CGT) and activists connected to municipal government in Avellaneda and Lanús. The regime utilized secret police structures influenced by models from Argentina's past and contemporary juntas, and purges extended into Policía Federal Argentina ranks, military academies, and provincial administrations in Córdoba Province and Santa Fe Province.

Economic Policies and Reforms

The junta reversed several economic measures associated with Perón including nationalizations and state intervention in industries like Yacimientos Petrolíferos Fiscales and sectors linked to Compañía Mercantil del Plata, pursued currency stabilization affecting the peso argentino, and sought to re-engage foreign capital from investors in United Kingdom and United States markets. Fiscal adjustments targeted subsidies to enterprises tied to Peronist labor policies and reformed tariff regimes impacting agro‑exporters in Rosario and cereal brokers operating in Bahía Blanca. The government's economic team drew on technocrats influenced by models from Chile and Brazil and negotiated trade and credit arrangements with institutions resembling the International Monetary Fund and banks connected to Banque de France and Bank of England.

Domestic and International Reactions

Domestically, opposition figures from the Radical Civic Union and Socialist Party (Argentina) debated participation in junta‑called elections while Peronist loyalists organized clandestine resistance and strikes in industrial zones such as Avellaneda and the Lanús belt. Internationally, governments including United States and United Kingdom navigated diplomatic recognition debates, while exiled Perón engaged with leaders in Venezuela and Spain and communicated through intermediaries in the Holy See. Coverage by international outlets like The New York Times, Le Monde, and The Times shaped global perceptions; regional actors such as Brazil and Chile monitored developments amid Cold War anxieties tied to NATO and Non-Aligned Movement considerations.

Legacy and Historical Assessment

Scholars and commentators continue to assess the Revolución Libertadora through studies of authoritarianism, labor history, and transitional justice, contrasting interpretations from historians aligned with revisionismo histórico and critics associated with liberal historiography tracing links to later coups such as the 1966 Argentine Revolution and 1976 National Reorganization Process. Debates focus on effects on the Justicialist Party's survival, the fate of labor confederations like the CGT, and institutional transformations at the Universidad de Buenos Aires and provincial legislatures. Memorialization battles involve sites such as Plaza de Mayo and archives housed in institutions like the Archivo General de la Nación, shaping contemporary Argentine politics, electoral realignments, and narratives advanced by politicians from factions within the Peronist movement and opponents in parties such as the Radical Civic Union.
