🇦🇷 Argentina

The advanced sedentary trading culture of the northwest fell under Inca rule shortly before European arrival. Inca influence also shaped the llama-raising Huarpe of the centre-west.

Colonisation came from Paraguay, Peru and Chile: Santiago del Estero in 1553, Londres 1558, Mendoza 1561, San Juan 1562, San Miguel de Tucumán 1565, Santa Fe and Córdoba in 1573, and San Luis in 1596. These foundations established the urban framework of colonial and modern Argentina.

Vespucci's expedition was followed by Juan Díaz de Solís in 1516 and Sebastian Cabot in 1526. Early explorers of the Río de la Plata reported abundant silver, giving the region its later name.

The first settlement lasted only until 1541. Juan de Garay re-founded the city in 1580, from which it grew to dominate the region.

Argentine territory had previously been subordinated to the Viceroyalty of Peru, whose silver and gold mines drew Spanish attention. The new viceroyalty gave Buenos Aires administrative primacy and became the entity to which independent Argentina was successor state.

Local militias twice defeated British expeditionary forces without Spanish assistance. The victories bolstered creole self-confidence and helped set the stage for the 1810 revolution.

Fighting began after the May Revolution and continued across the region, with campaigns in Córdoba, the Banda Oriental, Upper Peru and Paraguay. Argentine forces under San Martín crossed the Andes, secured Chilean independence and proclaimed the independence of Peru.

Local criollos formed a governing junta, beginning the process by which Argentina emerged as successor state to the Viceroyalty. It triggered the independence war and the enduring split between Centralists and Federalists.

The French-Argentine corsair attacked Spanish California, Peru and the Philippines, recruiting Filipino defectors into the Argentine navy. He also secured diplomatic recognition from King Kamehameha I of Hawaii, described as the first state to recognise Argentine independence, before his arrest in 1819.

The Assembly created a single executive office for the United Provinces during the independence war. The Supreme Directorship lasted until the Federalist victory at Cepeda in 1820.

Belgrano, San Martín and Güemes had proposed a monarchy under a descendant of the Inca, with Juan Bautista Túpac Amaru as candidate. The Congress instead created a republican, centralist state, fixing Argentina's constitutional form.

Delegates from the United Provinces of the Río de la Plata proclaimed independence on 9 July 1816, opening a decade of wars against Spanish royalist forces across the region.

The charter attempted to impose central authority over the provinces. Its rejection deepened the Centralist–Federalist conflict that dominated the following decades.

The clash between Centralists and Federalists dissolved the national executive. Argentina fragmented into effectively autonomous provinces for the following decade.

The 1826 constitution contained the first legal use of the name 'Argentine Republic'. Provincial revolt forced Rivadavia's resignation and the charter was discarded, resuming civil war.

After prevailing in the civil war, the Federalists established a loose confederal order led by the caudillo Rosas. His long regime withstood foreign blockades but his trade restrictions antagonised the interior provinces.

Rosas's Argentina engaged the Peru–Bolivian Confederation in regional conflict. Argentina emerged without territorial loss.

France blockaded Argentine ports during Rosas's rule. The regime remained undefeated and prevented further loss of national territory.

Britain and France jointly blockaded the Río de la Plata to force open river navigation. Rosas remained undefeated, preserving national territory but at heavy commercial cost.

Justo José de Urquiza defeated Rosas in 1852 and, as president of the Confederation, oversaw the constitutional convention at Santa Fe that in 1853 promulgated a liberal, federal constitution formalising the name 'Argentine Confederation'. It established the institutional framework still in use today, though Buenos Aires province did not accept it until 1860.

Buenos Aires had seceded after the 1853 Constitution. Its military defeat restored territorial unity, though on terms soon reversed at Pavón.

Immigrants from throughout Europe transformed the country between 1860 and 1930, with Italy and Spain providing the largest share of newcomers.

A decree fixed the official designation and that year's constitutional amendment ruled all names used since 1810 legally valid. It closed a long dispute over national nomenclature.

Mitre's victory over Urquiza secured Buenos Aires' predominance within the nation. With Sarmiento and Avellaneda he laid the institutional basis of the modern Argentine state.

Literacy rose from 22% to 65%, higher than most Latin American nations would reach fifty years later. The system underpinned the assimilation of mass immigration and the country's rapid modernisation.

Military incursions into the Pampa and Patagonia seized indigenous lands, roughly tripling effective national territory, with the land distributed among members of the Sociedad Rural Argentina who financed the campaigns. The Chaco conquest continued to the end of the century. Indigenous peoples were treated as inferior and denied the rights of Criollos and Europeans.

Ten consecutive federal governments from 1880 pursued liberal economic policies and promoted European immigration second only to that of the United States. Population grew fivefold and the economy fifteenfold, with wheat and frozen beef exports and railway mileage rising dramatically.

Argentine science won international respect from this period, alongside René Favaloro's later pioneering of coronary artery bypass surgery. These advances established the country's medical research standing.

Argentina claims 965,597 km2 of Antarctic territory and holds the world's oldest continuous presence there. The claim overlaps those of Chile and the United Kingdom and falls under the 1961 Antarctic Treaty, of which Argentina is a founding signatory with the Treaty Secretariat based in Buenos Aires.

Argentina surpassed Denmark, Canada and the Netherlands, with income 70% higher than Italy's and 400% higher than Brazil's. Despite this wealth, industrialisation lagged and much manufacturing remained labour-intensive into the 1930s.

The 1912 law established universal, secret and compulsory male suffrage, ending decades of electoral fraud and paving the way for the Radical Civic Union's first election victory two years later.

On the eve of the First World War Argentina stood among the world's richest nations. The subsequent relative decline is central to understanding the country's modern trajectory.

Argentina stayed out of the conflict under Yrigoyen. Neutrality preserved trading relationships but shaped later disputes over its alignment.

The first genuinely competitive national election ended the Conservative Republic dominated by the National Autonomist Party. Yrigoyen enacted social and economic reforms and aided small farms and businesses.

The Argentine cartoonist produced and released the earliest animated features. Argentina became Latin America's leading film producer by the early 1930s, a position held until the early 1950s.

On 27 August 1920 a team of medical students aired Wagner's Parsifal from Buenos Aires' Teatro Coliseo. It was a genuine world first in mass communications.

Precipitated by the Great Depression, the coup began the 'Infamous Decade' of fraudulent government to 1943. Though Argentina remained among the fifteen richest countries until mid-century, the coup marked the start of a steady economic and social decline into underdevelopment.

Elected in a fraudulent election after Uriburu's two-year rule, Justo concluded an agreement preserving British access to Argentine markets. It became emblematic of the dependency criticised during the Infamous Decade.

The coup ended the Infamous Decade's civilian facade and installed military rule. Juan Perón rose within the new government as head of the Labour Department and then defence minister in 1944.

Having stayed neutral through most of World War II with British support but American disapproval, Argentina declared war on 27 March 1945, roughly a month before the war ended in Europe. The late entry shaped its post-war international standing.

Perón defeated the UCR in a landslide in the 1946 general election as the Labour candidate, after being forced from office and briefly arrested in 1945; his Labour Party, later the Justicialist Party, became the most powerful force in Argentine history. His first presidency began a movement combining labour rights, economic nationalism and a strong executive that has shaped Argentine politics ever since, through repeated bans, returns and splits within the movement.

After World War II an era of Peronist populism under Juan Perón, combined with direct and indirect military interference in subsequent governments, dominated Argentine politics. Until about the mid-20th century the country's history had been marked by internal conflict between Federalists and Unitarians and between civilian and military factions.

Perón raised wages and working conditions, claimed near-full employment, and built a system of social assistance. The economy began to decline from 1950 amid heavy government expenditure and protectionism.

Perceived rivals faced threats, violence and harassment, and over 2,000 university professors were dismissed from public institutions. Union leaders such as Cipriano Reyes were arrested and tortured, with Reyes released only after the regime fell in 1955.

The reform doubled the electorate and consolidated Peronist support, with Eva Perón playing a critical mobilising role. It was a decisive extension of political rights in Argentina.

The first Latin American laureate, he discovered the role of pituitary hormones in regulating glucose. His prize established Argentina's international scientific reputation.

Life expectancy at birth rose from 60 to 76 years over the same period. Mortality patterns came to resemble those of developed nations, though Argentina ranked fourth in Latin America in 2006.

Two national territories were raised to provincial status. Misiones followed in 1953 and Formosa, Neuquén, Río Negro, Chubut and Santa Cruz in 1955.

Naval aircraft bombed the Plaza de Mayo in June 1955, killing about 300 people, before a September coup — the Revolución Libertadora — ended nine years of Peronist rule and forced Perón into exile in Spain. The new head of state, Pedro Eugenio Aramburu, proscribed Peronism and banned the party from elections for the next 18 years, distorting Argentine politics for decades.

Frondizi encouraged investment to achieve energy and industrial self-sufficiency and reversed a chronic trade deficit. His attempt to balance Peronists and the military alienated both and a coup removed him.

The Senate leader ascended after Frondizi's overthrow. Elections were repealed and Peronism prohibited once more.

Illia's government presided over a period of growth. He was ousted by a military coup in 1966.

Onganía established a military dictatorship intended to rule indefinitely, shutting Congress, banning political parties and dismantling student and worker unions. The repression fed the popular explosions and guerrilla violence of the following years.

Massive protests against Onganía's dictatorship erupted in Córdoba and Rosario. The unrest coincided with the targeting of trade unionists by paramilitaries, which some date as the start of the long political war.

The device was designed and developed by the Argentine surgeon. It stands among the country's foremost medical engineering achievements.

The guerrilla organisation's assassination of Aramburu marked the escalation of armed left-wing insurgency. It intensified the cycle of political violence that culminated in the Dirty War.

He discovered how organisms store energy by converting glucose into glycogen and identified compounds fundamental to carbohydrate metabolism. It was Argentina's second science Nobel.

The killing of captured guerrillas is cited among possible starting points of the Dirty War. It deepened the spiral of state and insurgent violence.

Pilots stopped accepting assignments from 3 August 2026 in protest at a government decree deregulating their profession, disrupting traffic around Greater Rosario, the country's main agricultural export corridor.

Brazil's foreign ministry reduced ties to chargé d'affaires level and postponed the return of its ambassador on 4 August 2026, after President Javier Milei repeatedly called Brazilian President Lula da Silva a thief at a political rally in São Paulo.

Senators approved the measure 37 votes to 33 in the early hours of 7 August 2026 after the governing bloc withdrew two chapters, including one easing rural land purchases by foreigners, to secure enough votes; the bill now goes to the Chamber of Deputies.

The proposal to overhaul the central bank's charter, including a ban on financing the state directly or indirectly, was presented in a nationwide broadcast on 30 July 2026 and formally entered the Chamber of Deputies the following week.

The deal, signed on 5 February 2026, reduced tariffs on most goods traded between the two countries and reinforced the political alliance between President Milei and the Trump administration.

Workers walked out on 19 February 2026 in protest at a labour reform bill proposed by the Milei government, disrupting transport and services in Buenos Aires and other cities.

The emergency was declared on 30 January 2026 across Chubut, Río Negro, Neuquén and La Pampa provinces as wildfires spread through Patagonia, freeing additional resources for firefighting and relief.

On 15 January 2026 the government listed the Muslim Brotherhood and affiliated groups in Egypt, Jordan and Lebanon as terrorist organisations, aligning its designations with those of the United States and Israel.

Milei's party strengthened its position in Congress. The result made it easier to push ahead with radical spending cuts and free-market reforms.

President Milei's party won the largest share of contested seats in both houses of Congress on 26 October 2025, strengthening his position after a heavy defeat in the Buenos Aires provincial vote weeks earlier.

The Peronist party won 47 per cent of the vote to La Libertad Avanza's 34 per cent on 7 September 2025, in a provincial election held seven weeks before the October midterm vote.

Activity recovered after the severe recession at the start of 2024. Annual inflation dropped sharply from the 2024 peak of around 220%.

In January 2024 the poverty rate reached its highest level since 2004, having stood at roughly 43% in 2023. By the second semester of 2024 it had fallen to 38%, the lowest since 2022, as inflation slowed to a monthly 2.4% in November.

The libertarian outsider defeated ruling coalition candidate Sergio Massa after Fernández declined to seek re-election in April 2023. Milei was sworn in on 10 December 2023, inheriting inflation and poverty at multi-decade highs.

More than 18,500 Russians had arrived by July 2023 following the 2022 invasion. It represents a notable new migration stream alongside long-standing Bolivian, Paraguayan and Peruvian flows.

The population had risen from 40,117,096 in 2010 and was estimated at 47,067,441 by 2024. Fertility had fallen to 2.3 children per woman by 2010 from a high of 7.0 in 1895.

The ruling Peronist coalition lost control of Congress for the first time in almost 40 years to Juntos por el Cambio. Losing the Senate hampered Fernández's judicial appointments and forced negotiation with the opposition on every bill.

The government failed to pay creditors by the due date. It marked another episode in Argentina's recurrent debt crises.

The Justicialist candidate won by nearly eight percentage points, with Cristina Kirchner as vice president. They took office in December 2019, months before the COVID-19 pandemic reached Argentina and amid corruption accusations against the Kirchner presidencies.

Defence spending had fallen to 0.74% of GDP by 2011, a historical minimum, with training and basic maintenance funding cut. The loss illustrated a steady erosion of Argentine military capabilities.

The programme targeted high inflation and large public deficits inherited from the previous administration. Recovery remained elusive: GDP shrank 3.4%, inflation totalled 240%, billions in sovereign debt were issued and poverty rose by the end of his term.

The settlement followed Macri's election and resolved a long-standing legal battle. It allowed Argentina to re-enter international capital markets for the first time in a decade.

After a tie in the first round on 25 October, the centre-right coalition candidate beat Daniel Scioli on 22 November and took office on 10 December 2015. He was the first democratically elected non-Peronist president since 1916 to complete his term without being overthrown.

The law passed by overwhelming majority with support from all major parties. The system had declined since the 1940s, carrying 1,400 times less freight by 1991 than in 1973.

The Cardinal Archbishop of Buenos Aires became Bishop of Rome on 13 March 2013. His election gave Argentina unprecedented visibility in the Catholic world.

Argentina was elected in 2012 to a nonpermanent seat on the United Nations Security Council, taking it up in January 2013 for the 2013–14 term. The two-year term reflected its diplomatic standing, while the country simultaneously participated in peacekeeping missions in Haiti, Cyprus, Western Sahara and the Middle East.

It was the second country in the Americas and tenth worldwide to do so. The reform marked a significant extension of civil rights.

The deal covered mission support facilities at the Pierre Auger Observatory, the world's foremost cosmic ray observatory. It embedded Argentina in international deep-space infrastructure.

Catholics fell from 76.5% in 2008 to 66% in 2017 and 63% by 2024, while the irreligious rose to around 20%. It marks a rapid secularisation of a historically Catholic society.

An estimated 750,000 inhabitants lacked official documents, and the scheme offered two-year residence visas in return for declaring status. Over 670,000 applications have been processed.

She promoted relations with Venezuela, Iran and Cuba while US and UK ties grew strained. Despite increased renewable energy production and subsidies, the economy was sluggish from 2011.

Duhalde brought elections forward after police killed two piqueteros. Kirchner took office on 26 May 2003 as the economic crisis was receding.

Building on Duhalde's neo-Keynesian policies, Kirchner attained fiscal and trade surpluses and rapid GDP growth, and paid off debts to the IMF. He also purged the military of officers with dubious human rights records and had the Full Stop and Due Obedience laws nullified as unconstitutional, resuming prosecution of the Junta's crimes.

Massive capital flight was met with a freeze on bank accounts under the corralito measures; as the currency board collapsed Argentina defaulted on its sovereign debt, unemployment surged above 20 per cent and nationwide riots and street protests forced President Fernando de la Rúa to resign in December 2001. Congress appointed Eduardo Duhalde acting president, who revoked the fixed exchange rate, wiping out much of the savings of working- and middle-class Argentines.

Economic decline from 1995, rising unemployment and recession undermined Menem's coalition. De la Rúa retained Menem's economic plan despite deepening crisis.

The status formalised close defence ties with the United States. Argentina also became an OECD candidate country in January 2022.

The reform allowed Menem to be elected for a second term. It reshaped the rules of executive power in the restored democracy.

CONAE has since launched two satellites successfully and developed the SAC series. Argentine-built satellites also include LUSAT-1 in 1990 and PEHUENSAT-1 in 2007.

It was the only South American country to contribute forces under UN mandate. Argentina has since remained involved in peacekeeping in Croatia/Bosnia, Cyprus and Haiti.

The treaty signed on 26 March 1991 created a common market among the four founding members, aiming to remove trade barriers and coordinate economic policy across the southern cone of South America.

Forest cover fell from 35,204,000 hectares in 1990 to 28,573,000 in 2020, about 10% of land area. Argentina scored 7.21/10 on the 2018 Forest Landscape Integrity Index, 47th of 172 countries.

The Tierra del Fuego, Antártida e Islas del Atlántico Sur Province completed the federal map. It also embodied Argentina's Antarctic and South Atlantic claims.

Deregulation, privatisation and the dismantling of protectionist barriers normalised the economy in the short term. He also pardoned officers sentenced under Alfonsín.

Economic crisis and hyperinflation destroyed Alfonsín's support and riots forced his early resignation. The Peronist Menem took over a country in monetary collapse.

His extensive work on antibodies won international recognition. It continued Argentina's record in the biomedical sciences.

Alfonsín's election victory in October 1983 ended seven years of military rule and restored civilian democracy. He had campaigned on prosecuting Proceso human rights violations, and the Trial of the Juntas sentenced all the coup's leaders, though under military pressure he then enacted the Full Stop and Due Obedience laws halting further prosecutions.

The disclosure marked a major step towards being able to assemble nuclear weapons. It confirmed the country's advanced nuclear technical base.

Argentine forces took South Georgia in March and invaded the Falklands on 2 April; a British task force forced their surrender on 14 June. Street riots followed the humiliating defeat, the military leadership stood down and Reynaldo Bignone began organising a transition to democracy.

Part of Operation Condor with other Southern Cone dictatorships, the campaign killed an estimated 15,000 to 30,000 left-wing activists, unionists, students and journalists, while guerrillas killed some 500–540 security personnel and up to 230 civilians. Argentina received technical support and military aid from successive United States administrations. By 1977 the ERP was subdued and a 1979 Montoneros counterattack was crushed.

The armed forces shut Congress, removed Supreme Court judges, banned parties and unions, and used forced disappearance against suspected guerrillas and sympathisers. The Proceso governed until the return of democracy in 1983.

The secret decrees empowered the military and police to annihilate subversion during Operativo Independencia, halting the ERP's rural insurgency in Tucumán. They legitimised the machinery of state terror later used by the junta.

Perón died of a heart attack on 1 July 1974 aged 78 and his wife and vice president took office. Her presidency saw the collapse of Argentine political and social systems and a constitutional crisis.

The reactor made Argentina the regional pioneer in civil nuclear power. Embalse followed in 1983 and Atucha II in 2011.

Perón's third term was marked by escalating conflict between left and right Peronist factions and the guerrilla campaigns of the ERP, Montoneros and the state-backed Triple A. He expelled the Montoneros from the party, driving them underground.

Right-wing union leaders and left-wing Montoneros youth fought as Perón arrived from Spanish exile. The bloodshed announced the internal war within Peronism.

With Perón still banned, his stand-in took office on 25 May 1973 and granted amnesty to those convicted of political assassinations and terrorism. His months-long tenure saw over 600 social conflicts, strikes and factory occupations in a single month before he resigned in July.

The state-backed far-right death squad was created to fight the Montoneros and the People's Revolutionary Army. Its campaign is among the events marking the beginning of the Dirty War.
