Revolución Libertadora (Argentina) was the 1955 military coup that removed President Juan Perón from power and initiated a period of military and civilian rule often termed the anti-Peronist interregnum. The coup combined air strikes, naval actions, and land maneuvers by factions of the Argentine Army, Argentine Navy, and Argentine Air Force against Perónist strongholds in Buenos Aires and provinces such as Buenos Aires Province, Cordoba Province, and Santa Fe Province. The episode reshaped institutions including the Argentine Constitution of 1949, the Justicialist Party, and relations with actors such as the Catholic Church, United States, and regional governments in Latin America.

Background and causes

Perón's presidencies (1946–1955) followed involvement in the Infamous Decade aftermath and the rise of labor activism centered on unions like the General Confederation of Labor (Argentina) and syndicates led by figures such as José Espejo and Avelino González. Policies of nationalization—notably of Central Bank of Argentina-related functions and railways from companies such as Ferrocarriles Argentinos—and social programs under the Third Positionalism-aligned Justicialist Party generated support among workers and opposition from industrialists, the Argentine Catholic hierarchy, and sections of the Conservative Party. Tensions over the 1951 Argentine Constitution amendments, conflicts with the Catholic Church culminating in disputes with Cardinal José María Ponce de León figures, and economic strains linked to trade partners like United Kingdom and United States produced fractures inside the Argentine Armed Forces between loyalists and anti-Peronist officers including future junta leaders.

Military coup and key events (1955)

The coup began with uprisings by navy elements aboard ships such as the ARA General Belgrano and air sorties by pilots sympathetic to officers like Pedro Eugenio Aramburu. Initial clashes occurred in Plaza de Mayo and neighborhoods including La Boca and San Telmo where Perón mobilized supporters including Eva Perón-era syndicalists. A crucial turning point was the bombing of Avenida 9 de Julio areas and the assault on Casa Rosada installations. After failures of pro-Perón counterattacks and defections within units influenced by commanders such as Benjamín Menéndez and Pascual Pistarini, Perón resigned or was deposed amid negotiations mediated by figures including José María Guido and international envoys from the Organization of American States. Interim rule passed to Eduardo Lonardi who proclaimed a policy of "neither victors nor vanquished" before being replaced by hardliners around Pedro Eugenio Aramburu who consolidated control through a junta.

Political developments and governance

The new authorities annulled measures of the 1949 Constitution and suspended Juan Perón-affiliated institutions such as the Justicialist Party. Decrees banned Peronist symbols and prohibited Perón's proscription, while legislative bodies including the Argentine Chamber of Deputies and Argentine Senate were purged and replaced with technocrats, military appointees, and civilian anti-Peronists linked to groups like the Radical Civic Union and National Democratic Party. The junta attempted to restore relations with international creditors and renewed ties with governments such as United States administrations and conservative cabinets in Chile and Uruguay. Subsequent caretaker administrations navigated between calls for early elections and extended military tutelage, culminating in a negotiated political exclusion of Peronist candidates.

Repression, purges and prosecutions

The regime implemented systematic purges targeting Peronist officials, trade union leaders, and cultural figures associated with the Evita era. High-profile arrests included regional governors, ministers from the Perón cabinet, and union bosses from the General Confederation of Labor (Argentina). Trials and military tribunals prosecuted alleged collaborators; some defendants faced execution or long imprisonments under commanders tied to Aramburu's security apparatus. Censorship removed Peronist literature and banned works by writers and artists sympathetic to Perón, while ministries overseeing the National University of La Plata and institutions such as the National Library underwent personnel changes, affecting academics like Rodolfo Ortega Peña and intellectuals linked to Peronist cultural policies.

Economic and social policies

The junta reversed select nationalizations and reoriented fiscal policy to stabilize foreign exchange reserves amid trade disputes with United Kingdom and commodity markets in North America. Economic teams included economists sympathetic to the Orthodox Economic School and sectors tied to Industrial Capitalists who sought currency stabilization, debt servicing, and foreign investment. Labor reforms curtailed union privileges established under Perón; welfare programs and social benefits were restructured, affecting beneficiaries of programs launched during the First Peronist Period. Agricultural export policies shifted to re-engage landowners in provinces like Cordoba Province and Santa Fe Province and to respond to market demands from buyers in Brazil and United States.

Domestic and international reactions

Domestic reactions spanned popular Peronist demonstrations, strikes organized by unions loyal to Perón, and support from sectors of the press such as conservative newspapers linked to families like the Mitre family. Prominent opponents praised the coup, including leaders from the Radical Civic Union, while Perón's exile to destinations like Paraguay, Panama, and ultimately Spain sparked international commentary. The United States government and other Western capitals cautiously engaged with the junta, balancing Cold War concerns and regional stability alongside criticisms from leftist parties and intellectual currents in Cuba and Mexico.

Legacy and historical assessment

The coup reshaped Argentine political development by entrenching a cycle of military interventions and civilian proscription that influenced later events such as the 1966 Argentine Revolution and the rise of guerrilla movements including the Montoneros and ERP (People's Revolutionary Army). Historians debate whether the overthrow advanced democratization or deepened polarization; scholars cite archival materials from institutions like the National Archives of Argentina and testimonies from actors including Pedro Eugenio Aramburu to assess consequences for constitutional order, labor rights, and civil liberties. The long-term legacy includes continuing contestation over Perón's social reforms, the symbolism of Eva Perón, and the legal proscription of Peronism which shaped party politics until its eventual re-entry into electoral competition.
