1930 Argentine coup d'état was a military overthrow that removed Hipólito Yrigoyen from the Presidency of Argentina on 6 September 1930, marking the end of a period of Radical Civic Union ascendancy and initiating a decade of conservative rule. The seizure combined actions by officers of the Argentine Army, elements of the National Navy of the Argentine Republic, and civilian allies from the Conservative Party and Unión Cívica Radical Antipersonalista. The event inaugurated the so-called "Infamous Decade" and influenced subsequent alignments among United States, United Kingdom, and regional actors.
Background
By the late 1920s Argentina experienced tensions among factions including the Radical Civic Union, the Conservatives, and the Socialists, while international pressures from the Great Depression, Wall Street Crash of 1929, and fluctuating commodity markets hit Buenos Aires exports. President Hipólito Yrigoyen faced opposition from provincial governors such as Marcelo T. de Alvear allies, and from military officers influenced by doctrines circulating in Europe and North America. Economic disputes over meatpacking and grain exports linked interests in Rosario, Córdoba, and Santa Fe to banking centers like Banco Nación and businessmen associated with Jorge Haro and Agustín P. Justo networks. Political polarization intensified with the rise of groups including the Unión Cívica Radical Antipersonalista and public demonstrations in Plaza de Mayo, where opponents of Yrigoyen clashed with supporters of the Radical Civic Union leadership.
Coup and Military Action
On 6 September 1930 a coordinated operation led by senior officers of the Argentine Army and elements of the National Navy of the Argentine Republic secured Casa Rosada and key installations in Buenos Aires without widespread urban warfare. Forces under José Félix Uriburu moved against loyal units remaining with Hipólito Yrigoyen, who was arrested and detained at Ollas y Sartenes facilities before transfer to military custody. The coup used units drawn from barracks in La Plata, Palermo, and Campo de Mayo, leveraging artillery placements near the Riachuelo and control of the Telegraph and Radio Argentina networks to announce the change. Some clashes occurred in provincial capitals such as Mendoza and Salta where local garrisons declared for the coup plotters; however, the operation avoided protracted sieges and relied on rapid occupation tactics developed by modernizing officers influenced by maneuvers practiced in France and Italy.
Key Figures
José Félix Uriburu, a career officer of the Argentine Army, became the de facto head after the overthrow; his circle included civilian backers from the Conservative elite and businessmen linked to Banco de la Nación Argentina. Opponents centered on former President Hipólito Yrigoyen and his inner Radical faction, with notable figures such as Marcelo T. de Alvear advocating institutional resistance while peripheral leaders like Lisandro de la Torre criticized both camps. Military planners and junior officers took cues from international military thought represented by names like Giovanni Giolitti-era Italian strategists and observers of Prussia; domestically, provincial strongmen and governors in Córdoba Province, La Rioja Province, and San Juan Province played pivotal roles. Civil actors included representatives of the Unión Industrial Argentina, landowners tied to the Estancias network, and legalists from institutions such as the Supreme Court of Argentina.
Domestic Consequences
The coup suspended the functioning of constitutional mechanisms overseen by the National Congress of Argentina and led to the proscription of elements of the Radical Civic Union. The new regime implemented interventions in provincial administrations, purged civil servants associated with Yrigoyen, and enacted economic measures favoring British and United States commercial interests in sectors centered on Buenos Aires Port exports. Electoral manipulation and fraud became hallmarks of the subsequent period, with conservatives deploying strategies later associated with the "Infamous Decade" to control legislatures in Santa Fe, Entre Ríos, and Corrientes. Labor organizations such as the Unión Ferroviaria and Confederación General del Trabajo faced repression and legal constraints while agrarian unions based in Rosario and Bahía Blanca saw their leaders detained. Cultural institutions in Buenos Aires including the Colon Theatre and university faculties experienced shifts in patronage toward conservative patrons.
International Reaction
Foreign capitals reacted quickly: the United States Department of State and diplomats from the United Kingdom monitored developments in Buenos Aires and reassessed commercial relations with Argentina's financial institutions such as Banco de la Nación Argentina and trading houses in London. Regional actors in Brazil and Chile recalibrated diplomatic ties, while international press organs in Paris and New York analyzed implications for commodity markets. The coup influenced policies at multilateral fora where representatives from Pan-American Union member states debated non-intervention and recognition. Some foreign investors and commercial consortia shifted contracts to favor firms in Liverpool and New York City, altering credit flows mediated by Barings Bank-affiliated networks.
Aftermath and Political Legacy
Uriburu's regime initiated constitutional experiments and flirtations with corporatist models inspired by Benito Mussolini and Fascist Italy that shaped policies during the 1930s, while establishing precedents for military intervention in Argentine politics later manifested in coups of 1943 and 1955. The overthrow weakened the institutional standing of the Radical Civic Union and facilitated the rise of political actors like Agustín P. Justo and sectors of the Conservative establishment, influencing social coalitions that produced the electoral configurations of the mid-1930s. Long-term impacts included altered relations with United Kingdom finance, changes in labor law affecting unions such as the CGT, and doctrinal shifts within the Argentine Army that echoed in later military doctrines. The 1930 event thus became a focal point in Argentine historiography and political science debates involving scholars referencing archives in Biblioteca Nacional Mariano Moreno and analyses by historians who compare the episode to other Latin American interventions such as the Brazilian events of 1930.
