The history of Paraguay

Paraguay is a landlocked country in the heart of South America, divided by the Paraguay River into a fertile, wooded east and the dry plains of the Chaco to the west. Its history begins with the Guaraní, whose language is still spoken by most Paraguayans today, a situation unique in the Americas. Spanish settlers from Asunción mixed with Guaraní society to form a largely mestizo colony, while Jesuit missions gathered tens of thousands of Guaraní into some of the most remarkable communities of the colonial world. Independent since 1811, Paraguay lived under a series of strongmen, suffered one of the most destructive wars in modern history between 1864 and 1870, won the Chaco War against Bolivia in the 1930s, and endured the 35-year dictatorship of Alfredo Stroessner before a return to elected government in the 1990s.

When Europeans arrived, the eastern half of present-day Paraguay belonged to Guaraní-speaking peoples, part of the great Tupi-Guaraní language family that stretched along the rivers and coasts of eastern South America. Estimates of their numbers in the Río de la Plata basin range from about 300,000 to as many as a million. They were settled farmers who cleared patches of forest to grow maize, manioc, beans, squash and sweet potatoes, supplementing their crops with hunting, fishing and gathering. Villages consisted of large communal houses sheltering many related families, each grouped around the authority of a chief whose standing rested on generosity, oratory and success in war.

Guaraní religion was animistic, centred on spirits of the forest and on shamans who led ritual song and dance, and its myths of creator beings such as Ñamandu and Tupã survive in modern Paraguayan folklore. War with neighbours was frequent, and captives could be ritually killed and eaten.

West of the river the Chaco was home to very different peoples, including the Guaicurú-speaking groups and others who lived by hunting, gathering and seasonal farming across the scrubland. They resisted outsiders fiercely, and the Chaco remained largely beyond colonial control until the twentieth century.

The first Europeans to cross the region were survivors of Juan Díaz de Solís's expedition of 1516 to the Río de la Plata. One of them, the Portuguese Aleixo García, led a force of about 2,000 Guaraní warriors inland towards the silver of the Inca Empire in the 1520s. In 1537, during the expedition of Pedro de Mendoza, Juan de Salazar de Espinosa and Gonzalo de Mendoza founded Asunción on 15 August. When the first settlement at Buenos Aires was abandoned in 1541, Asunción became the centre of Spanish power in the whole region, the base from which colonists later founded Santa Cruz in Bolivia and refounded Buenos Aires in 1580.

The Guaraní initially welcomed the Spaniards as allies against their enemies in the Chaco. In Guaraní society, alliances were sealed through women, and Spanish men took Guaraní wives and concubines in large numbers. Domingo Martínez de Irala, elected governor by the settlers under a privilege granted by Charles V, encouraged these unions, and within a generation the colony was largely mestizo, raising children who were Spanish in law but often Guaraní in speech. The relationship was also coercive: Spaniards seized and traded Guaraní women despite royal prohibitions, and late in his rule, before his death in 1556, Irala gave in to settler pressure and introduced the encomienda, dividing about 20,000 Guaraní among 320 settlers who were entitled to their labour. Abuse under the system provoked large Guaraní revolts in 1560 and 1561, and uprisings continued for decades. Epidemics of European diseases cut the Guaraní population sharply.

Paraguay became a poor frontier province of the Viceroyalty of Peru, governed from distant Lima. With no mines and little trade, its settlers lived from cattle, yerba mate and the labour of Indigenous people, and they faced constant raids from Chaco peoples to the west and from Portuguese slave hunters to the east.

The Jesuits arrived in 1588, and in 1609 three of them founded San Ignacio Guazú, the first of their reductions, settlements in which scattered Guaraní communities were gathered under missionary supervision, separated from Spanish settlers and protected from the encomienda. The missions spread quickly, including fifteen in the Guayrá region of what is now the Brazilian state of Paraná. Concentration had a terrible cost: from 1618 epidemics swept through the crowded settlements and killed thousands.

From 1628 the bandeirantes, slave-raiding expeditions from São Paulo in colonial Brazil, fell on the Guayrá missions and carried off thousands of Guaraní to be sold. Between 1631 and 1638 the Jesuits led about 12,000 survivors on a long retreat of roughly 500 kilometres south-west into Spanish territory, between the Paraná and Uruguay rivers. There the Crown allowed the Guaraní to bear firearms, and in 1641 a mission army defeated a large force of bandeirantes and their Tupi allies at the Battle of Mbororé, ending the worst of the raids.

In their new heartland the reductions grew into thirty towns spread across present-day Paraguay, Argentina and southern Brazil, with a population that peaked at about 141,000 in 1732. Each was built around a great church and plaza, with workshops and communal fields. The Guaraní built churches in stone, carved statues, made musical instruments and performed baroque music, and the Jesuits printed books in Guaraní, helping to turn it into a written language. Historians still debate whether the missions were chiefly a refuge that preserved Guaraní life and language or a paternalist regime of strict discipline. Asunción's settlers resented the missions, and the Comunero revolt of 1721 to 1735 was partly aimed at the Jesuits.

The end came from Europe. Under the Treaty of Madrid of 1750, Spain ceded seven missions east of the Uruguay River to Portugal, and their Guaraní inhabitants were ordered to leave. They refused, and in the Guaraní War of 1754 to 1756, in which their leader Sepé Tiaraju was killed, a joint Spanish and Portuguese army crushed them. In 1767 Charles III expelled the Jesuits from the Spanish Empire, leaving about 89,000 Guaraní in the thirty missions. Under secular administration the towns declined, their people dispersed, and by 1801 the population had fallen to about 45,000. The ruins of missions such as Trinidad and Jesús are now World Heritage sites.

In 1776 Paraguay was placed in the new Viceroyalty of the Río de la Plata, governed from Buenos Aires, whose control of river trade and taxes Paraguayans resented. When Napoleon's invasion of Spain shattered royal authority and Buenos Aires formed its own government in 1810, Paraguay refused to follow its lead. A force sent from Buenos Aires under Manuel Belgrano was defeated at Paraguarí and Tacuarí in early 1811. Then, on 14 and 15 May 1811, Paraguayan officers deposed the Spanish governor in a bloodless rising, and a junta took power. A treaty with Buenos Aires in October implicitly recognised Paraguay's separate existence, making it one of the first states to emerge from the Spanish American wars of independence.

The dominant figure of the new state was José Gaspar Rodríguez de Francia, a lawyer and doctor of theology. Named one of two consuls in 1813, he became sole dictator in 1814 and dictator for life in 1816. Francia sealed Paraguay's borders, restricting trade and travel to protect the country from absorption by Buenos Aires or Brazil. He broke the power of the Spanish-born elite, decreeing in 1814 that Spaniards could not marry one another, only Indigenous, African or mestizo partners; he brought the Church under state control and closed the monasteries; and he took about half the land into state ownership, leasing much of it cheaply to peasants. He died in office in 1840, leaving a self-sufficient, isolated and egalitarian but tightly controlled state.

His successor, Carlos Antonio López, who ruled from 1844 until his death in 1862, opened the country. Paraguay formally proclaimed its independence in 1842 and gained wider recognition. López hired foreign engineers, built a railway, a shipyard, a telegraph and an ironworks, expanded schooling and the army, and in 1848 declared the Indigenous people of the former missions citizens while distributing their last communal lands. The population grew from about 220,000 in 1840 to about 400,000 by 1860. He was succeeded by his son Francisco Solano López.

Francisco Solano López inherited a strong army and a tangle of disputes with his much larger neighbours over borders and river navigation. In 1864 the Empire of Brazil intervened in a civil war in Uruguay, toppling a government friendly to Paraguay. López responded in November 1864 by seizing a Brazilian steamer and invading the Brazilian province of Mato Grosso; when Argentina refused his troops passage, he invaded Argentine territory too. On 1 May 1865 Brazil, Argentina and Uruguay signed the Treaty of the Triple Alliance, which gave the war its other name.

The Brazilian navy destroyed Paraguay's fleet at the Battle of Riachuelo in June 1865, and the Allies invaded Paraguay in 1866. At Curupayty in September 1866 Paraguayan defenders inflicted a crushing defeat that halted the Allied advance for months, but under the Brazilian commander the Duke of Caxias the Allies besieged and took the river fortress of Humaitá in 1868 and occupied Asunción in January 1869. López fought on in the interior with an army increasingly made up of boys and old men; at Acosta Ñu in August 1869 many of the Paraguayan dead were children. López had many suspected traitors, including relatives, tortured and executed. He was killed at Cerro Corá on 1 March 1870, ending the war.

The war was a demographic catastrophe, caused by battle, disease, hunger and the collapse of farming. Paraguay probably had about 450,000 people before it began. The scale of loss is one of the most debated questions in South American history: most estimates of Paraguayan deaths run from about 175,000 to 300,000, and leading studies suggest that between 60 and 69 percent of the population died, with men worst affected, though a minority of historians have argued for far lower figures. The 1886 census counted about 330,000 inhabitants. Paraguay gave up claims to almost 40 percent of the territory it had claimed, ceding lands to Brazil and Argentina, and Brazilian and Argentine troops occupied the country until 1876.

Postwar governments sold vast areas of state land, much of it to foreign companies, turning many peasants into landless labourers on yerba and timber estates. Two parties that took shape in 1887, the Colorados and the Liberals, would dominate politics thereafter. The Colorados ruled until a revolution in 1904 brought the Liberals to power; their era to 1936 saw 21 governments and two civil wars.

The Chaco itself was claimed by both Paraguay and Bolivia, which had lost its Pacific coast to Chile in 1879 and sought an outlet to the Atlantic by the Paraguay River; rumours of oil added to the tension. Clashes between forts escalated into full war in 1932. Paraguay's commander, José Félix Estigarribia, used mobility and encirclement against a larger Bolivian army fighting far from its highland base, taking the fort of Boquerón in September 1932 and encircling thousands of Bolivian troops at Campo Vía in December 1933. A ceasefire took effect in June 1935. About 36,000 Paraguayans and between 56,000 and 65,000 Bolivians died, many from thirst and disease. The peace treaty signed in Buenos Aires in 1938 gave Paraguay about three-quarters of the disputed territory.

Victory brought instability. In February 1936 army officers led by Colonel Rafael Franco overthrew the Liberal government and launched reforms including land redistribution and an eight-hour working day, before being ousted in 1937. Estigarribia became president in 1939 but died in a plane crash in 1940, and General Higinio Morínigo ruled as a military dictator through the years of the Second World War. In 1947 a coalition of Febreristas, Liberals and Communists rose against him, and in the civil war that followed, Colorado militias and army units, including a regiment commanded by Alfredo Stroessner, crushed the rebellion. Tens of thousands fled into exile, and the Colorado Party became the dominant force in the state.

On 4 May 1954 Stroessner, by then commander of the army, overthrew President Federico Chaves. Elected unopposed later that year, he ruled until 1989 through a system resting on the army, the Colorado Party and the government, renewing a state of siege that suspended civil liberties and winning a series of fraudulent elections. His staunch anti-communism earned close support from the United States during much of the Cold War. Political opponents, peasant organisers, students and clergy were imprisoned, tortured, exiled or killed, and Paraguay took part in Operation Condor, the cross-border campaign of repression run by South American military regimes in the 1970s. The Truth and Justice Commission reported in 2008 that about 425 people were executed or disappeared under the dictatorship, almost 20,000 were detained and more than 20,000 forced into exile. The Aché, a forest people of eastern Paraguay, were hunted, killed and sold into servitude as settlers took their lands, and in the 1970s the regime faced international accusations of genocide against them.

The economy boomed in the 1970s with the clearing of the eastern forests for farming and the building, with Brazil, of the giant Itaipú dam on the Paraná. By the 1980s the dictatorship was isolated, and on 3 February 1989 Stroessner was overthrown by General Andrés Rodríguez, his close associate. He went into exile in Brazil, where he died in 2006. In 1992 the discovery of police files known as the Archives of Terror documented the repression of the era and of Operation Condor.

Rodríguez was elected president in 1989, and a new constitution in June 1992 established multiparty democracy and limited presidents to a single term. Juan Carlos Wasmosy, elected in 1993, was the first civilian president in nearly forty years. The transition was turbulent: the army commander Lino Oviedo attempted a coup in 1996, and in March 1999 the assassination of Vice-President Luis María Argaña and the killing of protesting students in Asunción forced President Raúl Cubas to resign. The Colorado Party, however, retained power through every election until 2008, when Fernando Lugo, a former Catholic bishop backed by a broad opposition coalition, won the presidency.

In June 2012 a police eviction of landless farmers at Curuguaty ended in a clash that killed six police officers and eleven farmers. Within a week Congress impeached and removed Lugo by overwhelming majorities. Paraguay's courts upheld the process as constitutional, while Lugo's supporters and several neighbouring governments called it a parliamentary coup, and Mercosur suspended Paraguay until new elections were held. The Colorados returned to power with Horacio Cartes in 2013 and Mario Abdo Benítez in 2018.

In 2023 Santiago Peña of the Colorado Party was elected president with about 44 percent of the vote and took office in August. Paraguay, one of the world's largest exporters of soybeans and beef, has had one of the region's faster-growing economies, though concerns about corruption, organised crime and land inequality remain prominent, and protests against the government began in September 2025. Paraguay remains one of the few countries to recognise Taiwan rather than the People's Republic of China, a stance Peña has maintained. Its population of about 6.5 million is overwhelmingly bilingual in Spanish and Guaraní, both official languages.
