A Journey Through the Ages
Argentina stretches almost 3,700 kilometres from the high Puna and the forests of the Chaco to the Pampas, the deserts of Patagonia and the islands of Tierra del Fuego. For more than thirteen thousand years its lands belonged to many peoples, from the hunters who stencilled their hands in the Cueva de las Manos to the farmers of the Andean northwest, which the Inca joined to their empire in the fifteenth century.
Spain founded its cities from the 1550s and for two centuries governed the region as a remote frontier of Peru, until Buenos Aires became the capital of a viceroyalty in 1776. The May Revolution of 1810 and the declaration of independence in 1816 were followed by decades of civil war between Buenos Aires and the provinces.
The Constitution of 1853, railways and millions of immigrants made Argentina one of the richest countries in the world by 1910. In the twentieth century Radicals, Perón and a long series of military coups competed for power, ending in the dictatorship of 1976–1983 and the Falklands (Malvinas) War. Democracy, restored in 1983, has survived hyperinflation, the collapse of 2001 and repeated debt crises.
Explore the ten ages below through selected events from the timeline.
13,000 BCE – 1515
Thirteen thousand years before the conquest.
Hunter-gatherers reached the far south of the Americas at the end of the Ice Age and left their hand stencils on the walls of the Cueva de las Manos. In the Andean northwest, villages of farmers and llama herders gave rise to the Tafí, Condorhuasi, Ciénaga and Aguada cultures and the fortified towns of the Diaguita, while the Guaraní, the Huarpe, the Querandí, the Tehuelche and the canoe peoples of Tierra del Fuego lived by their own traditions. From about 1471 the Inca absorbed the northwest and Cuyo into their empire, building roads, waystations and mountaintop shrines.

People hunted giant ground sloths and wild horses on the Pampas at Arroyo Seco at the end of the Ice Age.

Farmers of the Tafí valley raised carved standing stones beside their fields and houses.

Fortified towns such as Tilcara and Quilmes crowned the hills of the Andean valleys.

The empire of Cusco extended its roads, waystations and shrines south to Mendoza.
1516 – 1599
Explorers, conquistadors and the first cities.
Juan Díaz de Solís entered the Río de la Plata in 1516, and Magellan found the strait at the tip of the continent in 1520. Pedro de Mendoza's first Buenos Aires (1536) was abandoned, and the Spanish base moved to Asunción. Expeditions from Peru, Chile and Paraguay then founded the cities that still anchor Argentina, from Santiago del Estero (1553) to Mendoza, Tucumán, Córdoba, Santa Fe and Juan de Garay's second Buenos Aires of 1580, amid long wars with the Diaguita and other peoples.

Juan Díaz de Solís entered the great estuary in 1516 and was killed on its shore.

Magellan's fleet found the passage between the oceans at the tip of the continent.

Pedro de Mendoza's settlement of 1536 was abandoned within five years.

Santiago del Estero, founded in 1553, is the oldest surviving city of Argentina.
1600 – 1809
A frontier of the empire becomes a viceroyalty.
For two centuries the region was a remote frontier of the Viceroyalty of Peru, living on cattle, mules for the silver mines of Potosí and contraband through Buenos Aires. Jesuit missions organised tens of thousands of Guaraní, the Calchaquí valleys resisted until the 1660s, and Portugal contested the Río de la Plata from Colonia do Sacramento. In 1776 Charles III made Buenos Aires the capital of a new viceroyalty, and in 1806–1807 its militias drove off two British invasions.

Jesuit reductions gathered tens of thousands of Guaraní in mission towns along the Paraná.

The Jesuit college of 1613 became the oldest university in Argentina.

Portugal's Colonia do Sacramento faced Buenos Aires across the river for a century.

Militias of Buenos Aires drove out British armies in 1806 and 1807.
1810 – 1820
From the May Revolution to independence.
The May Revolution of 1810 replaced the viceroy with a junta in Buenos Aires. Juntas, triumvirates and Supreme Directors fought royalist armies in Upper Peru, lost Paraguay and the Banda Oriental, and quarrelled with Artigas's Federal League, while Belgrano created the flag and the Assembly of the Year XIII abolished titles and freed the children of slaves. The Congress of Tucumán declared independence on 9 July 1816, and San Martín's Army of the Andes crossed the cordillera to liberate Chile and Peru.

On 25 May 1810 a junta replaced the viceroy in Buenos Aires.

Manuel Belgrano raised the blue and white flag on the banks of the Paraná at Rosario.

San Martín's Army of the Andes crossed the cordillera to liberate Chile.

The battle of Maipú sealed Chilean independence in 1818.
1821 – 1852
Unitarians, Federalists and the age of Rosas.
After the fall of the Directory in 1820 the provinces governed themselves, and Unitarians and Federalists fought over the shape of the nation. Rivadavia's presidency and the war with Brazil ended with Uruguay's independence and the execution of Dorrego. Juan Manuel de Rosas, governor of Buenos Aires with the sum of public power, then dominated the Argentine Confederation for two decades, defying French and Anglo-French blockades, until Urquiza defeated him at Caseros in 1852.

Bernardino Rivadavia's presidency of 1826 ended amid war with Brazil.

In 1835 Juan Manuel de Rosas took the sum of public power in Buenos Aires.

In exile in Chile, Sarmiento wrote Facundo against the caudillos.

Urquiza's Grand Army defeated Rosas in 1852.
1853 – 1879
A constitution, a nation and its frontier.
The Constitution of 1853 created a federal republic, but Buenos Aires seceded until its victory at Pavón reunited the country in 1861. Mitre, Sarmiento and Avellaneda built a national state with railways, schools, a civil code and the first census, while Argentina fought Paraguay in the War of the Triple Alliance. In 1879 Roca's Conquest of the Desert ended the independence of the peoples of the Pampas and Patagonia, a campaign many historians now describe as genocide.

Mitre's victory at Pavón brought Buenos Aires back into the republic.

Argentina, Brazil and Uruguay fought Paraguay from 1865 to 1870.

José Hernández's Martín Fierro became the national epic.

Roca's army reached the Río Negro in 1879, ending indigenous independence on the Pampas.
1880 – 1929
Granary of the world and the first mass democracy.
Federalised Buenos Aires became one of the great cities of the world as railways, refrigerated ships and millions of European immigrants turned the Pampas into a granary and pasture for Europe. The National Autonomist Party ruled through restricted elections until the Radical revolts and the Sáenz Peña law of 1912 opened the vote, bringing Hipólito Yrigoyen to power in 1916. Tango, the university reform and the labour conflicts of the Tragic Week and Patagonia Rebelde marked the new mass society.

Buenos Aires was federalised in 1880 and the province built La Plata as its new capital.

Jewish colonists founded Moisés Ville among the farming colonies of the Pampas.

The Sáenz Peña law of 1912 made voting secret and compulsory for men.

Hipólito Yrigoyen became the first president elected under the new law.
1930 – 1955
Coups, fraud and the rise of Perón.
The coup of 1930 began half a century of military interventions. The Concordancia governed through fraud during the Depression, until officers seized power again in 1943. Colonel Juan Perón built a following among workers and was carried to power by the mass rally of 17 October 1945. With Eva Perón he nationalised railways, extended social rights and votes for women, and ruled until the Revolución Libertadora overthrew him in 1955.

General Uriburu overthrew Yrigoyen, the first of six coups in the century.

Carlos Gardel, the voice of tango, died in a plane crash in 1935.

Eva Perón's foundation and her death in 1952 made her a figure of devotion.

Women voted in a national election for the first time in 1951.
1955 – 1983
Proscription, violence and dictatorship.
With Peronism banned, civilian presidents alternated with military regimes, guerrilla groups and the Cordobazo of 1969. Perón returned in 1973 and died in 1974, leaving the country to his widow Isabel amid political violence. The junta that seized power in 1976 waged a "Dirty War" in which thousands were disappeared, while the Mothers of the Plaza de Mayo demanded to know their fate. The defeat in the Falklands (Malvinas) War of 1982 brought the dictatorship down.

Workers and students rose in Córdoba in 1969 against the military government.

After 17 years of exile Perón came home in 1972 and won a third presidency.

The armed forces overthrew Isabel Perón and began the National Reorganization Process.

The junta's invasion of the islands ended in defeat after 74 days.
1983 – present
Democracy, crisis and renewal.
Raúl Alfonsín restored democracy in 1983 and the juntas were tried, but hyperinflation ended his government early. Carlos Menem pegged the peso to the dollar and privatised state companies; the convertibility regime collapsed in the crisis of 2001, when five presidents followed one another in two weeks. The Kirchners governed for twelve years of recovery and conflict, Mauricio Macri and Alberto Fernández struggled with debt and inflation, and in 2023 the libertarian Javier Milei won the presidency promising to shrink the state.

The CONADEP report documented the crimes of the dictatorship.

Riots and the corralito brought down President de la Rúa.

Archbishop Jorge Mario Bergoglio of Buenos Aires became the first pope from the Americas.

Messi's Argentina won its third World Cup in Qatar in 2022.

From the dance halls of Buenos Aires to the courtroom where the juntas were tried, the history of Argentina has given the world the tango and a great literature, a nation built by immigrants, a federal constitution, the political tradition of Peronism, a model of justice after dictatorship, Nobel prizes in science and peace, and a passion for football.
Born in the tenements and dance halls of Buenos Aires and Montevideo in the late nineteenth century, where the music of European immigrants, Afro-Argentines and creoles met, the tango conquered Paris and then the world. Carlos Gardel made it a song, Astor Piazzolla a concert music. Tango is on UNESCO's list of the intangible heritage of humanity, beside the chacarera, the zamba and the folk music of the provinces.
Sarmiento's Facundo and José Hernández's Martín Fierro made the gaucho and the clash of "civilisation and barbarism" the founding themes of Argentine letters. In the twentieth century Jorge Luis Borges, Julio Cortázar, Victoria Ocampo's magazine Sur, Ernesto Sabato and Quino's Mafalda gave Buenos Aires a place among the literary capitals of the world.
Between 1870 and 1930 some six million Europeans, above all Italians and Spaniards, but also Jews from Eastern Europe, Germans, Welsh, Syrians and Lebanese, settled in Argentina. They transformed its cities, its speech, its food and its politics, and made Buenos Aires one of the great cosmopolitan cities of the Americas, while the Indigenous peoples and the Afro-Argentine community were long written out of the national story.
The long struggle between Buenos Aires and the provinces produced the Constitution of 1853, inspired by Juan Bautista Alberdi and still in force after its reforms. Its federal design, its promise to welcome immigrants and its later guarantees of social rights (1957) and of international human-rights treaties (1994) shaped the Argentine state.
Juan and Eva Perón built one of the most enduring political movements of Latin America, uniting trade unions, social rights and nationalism. Peronism has since spanned the left and the right, and Peronist presidents have governed for longer than any other political force since 1946. It remains the axis around which Argentine politics turns.
After the dictatorship, the CONADEP report Nunca Más and the Trial of the Juntas of 1985 became models of transitional justice. The Mothers and Grandmothers of the Plaza de Mayo, whose search has identified more than 130 children stolen as babies, pioneered the use of genetic testing to restore identities, and the trials reopened from 2005 continue today.
Argentina has five Nobel laureates: Carlos Saavedra Lamas and Adolfo Pérez Esquivel for peace, Bernardo Houssay for medicine, Luis Federico Leloir for chemistry and César Milstein, co-inventor of monoclonal antibodies. Juan Vucetich created fingerprint identification, and the Córdoba observatory, Antarctic bases since 1904 and a nuclear and satellite industry reflect a long scientific tradition.
Football arrived with British railwaymen and became a national passion: Argentina played in the first World Cup final in 1930 and won the tournament in 1978, 1986 and 2022, with Diego Maradona and Lionel Messi among the greatest players of all time. Juan Manuel Fangio won five Formula One world titles, and Argentines have also been world champions in polo, basketball and boxing.
The timeline is built from the project's own research dossier and its event, ruler and map datasets, checked against English and Spanish Wikipedia, Encyclopaedia Britannica, official Argentine sources such as INDEC census data and the Boletín Oficial, UNESCO and, for 2024–2026, major news organisations. Linked articles are starting points for verification, not proof that every claim has been independently checked. Prehistoric dates and the traditional date of the Inca conquest are approximate, and contested figures, from the Conquest of the Desert to the victims of the dictatorship, are flagged where they appear. The most recent events rest on news reports that should be re-checked; historical frontiers on the map are approximate.
Every event and every ruler has its own sources. See Sources & Further Reading in each timeline entry and ruler profile.
