Argentine military history Argentine armed forces trace roots to colonial militias in the Viceroyalty of the Río de la Plata and revolutionary armies of the Spanish American wars of independence led by figures like José de San Martín and Manuel Belgrano. The 19th century saw state formation, caudillo politics exemplified by Juan Manuel de Rosas, and international wars such as the Cisplatine War and the Paraguayan War. Twentieth-century trajectories include interventionist politics culminating in military juntas under leaders like Jorge Rafael Videla and the 1982 Falklands War under Leopoldo Galtieri, followed by democratization, reform, and professionalization of the Argentine Army, Argentine Navy, and Argentine Air Force.

Early colonial militias and War of Independence (16th–1820s)

Colonial defense in the Viceroyalty of the Río de la Plata relied on local militias and institutions such as the cabildo against threats from British invasions of the Río de la Plata and privateers, involving officers who later featured in independence like Manuel Belgrano and Juan Martín de Pueyrredón. The May Revolution of 1810 led to the creation of the Primera Junta and expeditionary campaigns including the Army of the Andes organized by José de San Martín, which conducted the Crossing of the Andes and campaigns in Chile and Peru. Simultaneously, provincial caudillos and military leaders such as Facundo Quiroga influenced the struggle between centralists and federalists culminating in battles like Tacuarembó and the consolidation of independence after the Congress of Tucumán.

Organization and modernization of the 19th century

Post-independence Argentina restructured forces amidst state-building under leaders like Domingo Faustino Sarmiento who promoted European military models and education, importing officers such as Julián Martínez de Hoz and reforms influenced by Prussia. The Argentine Army professionalized with institutions like the Colegio Militar de la Nación and the Escuela Naval Militar encouraged technological adoption including steamships for the Argentine Navy and artillery modernization. Military doctrine and conscription evolved during presidencies of Bartolomé Mitre and Roca, shaping force projection in campaigns such as the Conquest of the Desert and frontier policing in Patagonia.

Interstate wars and border conflicts (19th–early 20th century)

Argentina fought regional wars including the Cisplatine War (against Brazil over the Eastern Bank of the Uruguay, later Uruguay), and the devastating Paraguayan War (Triple Alliance of Argentina, Brazil, Uruguay vs Paraguay), with notable engagements like Curupayty and sieges such as Humaitá. Border campaigns against indigenous confederations culminated in the Conquest of the Desert under Julio Argentino Roca, while naval incidents such as the Sarmiento-era actions and the intervention in the Río de la Plata reflected regional power projection. Diplomatic instruments like the Treaty of Pilar and arbitration by figures such as Richard Cobden affected postwar settlements.

Role in politics: coups, juntas, and military governments (1930–1983)

The military intervened politically in the 1930 1930 Argentine coup d'état installing conservative regimes; later coups included the 1943 Revolución del 43 bringing figures like Pedro Pablo Ramírez and later facilitating the rise of Juan Domingo Perón. The 1955 Revolución Libertadora ousted Perón and led to cycles of military rule and intervention culminating in the 1966 Argentine Revolution and the 1976 coup that installed the National Reorganization Process. Senior officers in bodies like the Joint Chiefs of Staff (Argentina) and leaders such as Jorge Rafael Videla and Emilio Massera ran policy through juntas, impacting institutions including the Policía Federal Argentina and international relations with United States and United Kingdom.

The Dirty War and human rights abuses (1976–1983)

The National Reorganization Process oversaw the campaign known as the Dirty War targeting alleged subversives through secret detention centers like ESMA and operations coordinated by bodies such as the Anticommunist Alliance and Operation Condor. Tactics included forced disappearances, torture, and state terrorism affecting civilians, students, and unionists, with victims and activists like Madres de Plaza de Mayo and H.I.J.O.S. seeking justice. International responses involved organizations like Amnesty International and the Inter-American Commission on Human Rights, and post-dictatorship trials would later prosecute perpetrators in cases tied to figures such as Jorge Rafael Videla.

Falklands War (1982)

In April 1982 the Argentine military junta under Leopoldo Galtieri and the Argentine Navy launched Operation Rosario to seize the Falkland Islands (Islas Malvinas), occupying Stanley and engaging the British Task Force led by HMS Hermes and commanders including Admiral Sir John "Sandy" Woodward. Major battles included the Battle of Goose Green, Battle of San Carlos, and the Battle of Mount Tumbledown culminating in British recapture and Argentine surrender. The war influenced domestic legitimacy, precipitating the fall of the junta, and left lasting impacts on veterans' organizations like Veteranos de Guerra and bilateral relations with the United Kingdom and Chile.

Post-dictatorship reforms and the modern Argentine Armed Forces (1983–present)

Democratic governments restored civilian supremacy with prosecutions under judges like Julián Ercolini and legislative measures including repeal and subsequent reform of amnesty laws such as the Full Stop Law (Ley de Punto Final) and the Due Obedience Law, later annulled by the National Congress. Presidents like Raúl Alfonsín, Carlos Menem, Néstor Kirchner, and Mauricio Macri implemented defense restructuring, budget cuts, and professionalization of the Argentine Navy, Argentine Air Force, and Argentine Army with missions in UNPROFOR, MINUSTAH, and peacekeeping under United Nations mandates. Contemporary challenges include modernization programs, procurement debates involving suppliers like France and Brazil, disaster relief operations after 1999 Río de la Plata floods and Antarctic logistics via Marambio Base, and ongoing memory and justice efforts by groups such as Abuelas de Plaza de Mayo.
