History of Brazil
A land of hundreds of nations before 1500, the destination of nearly half of all enslaved Africans brought to the Americas, and the only monarchy the New World's republics ever tolerated
Brazil's story runs from a coast home to millions of Indigenous people speaking hundreds of languages, through a Portuguese colony built first on a red dyewood and then on sugar, gold, and the forced labor of nearly five million enslaved Africans, more than any other place in the Americas. A prince declared it independent in 1822 and crowned himself emperor; his son ruled a monarchy that outlasted every neighboring republic until a bloodless coup ended it in 1889. The 20th century brought Getulio Vargas and his Estado Novo, a purpose-built modernist capital raised from empty savanna, a 21-year military dictatorship whose torture and killings a national commission later documented, and a democracy that finally beat hyperinflation with a new currency in 1994.

Long before any European reached the coast, the territory that became Brazil held a native population in the millions, divided among hundreds of tribes and separate language groups. The Library of Congress country study records four major language families: Ge, Tupi, Carib, and Arawak speakers, plus the Nambicuara. The Tupi speakers, who had displaced the Ge along the coast, were the peoples the Portuguese met first in 1500. Population estimates vary widely: demographer William M. Denevan suggested 3,625,000 people for Brazil's Amazon Basin alone, with another 4,800,000 in other regions, while historian John Hemming estimated more conservatively at 2,431,000 for Brazil as a whole. These figures are reconstructions, not counts, and scholars disagree on them by millions.
Why it matters: The size and diversity of Brazil's pre-contact population is the baseline against which the colonial catastrophe is measured. Within decades of contact, tens of thousands of these people died of smallpox, measles, tuberculosis, typhoid, dysentery, and influenza, with whole peoples likely annihilated without ever meeting a European, as disease traveled ahead of the colonists along Indigenous trade routes.
How we know: The population figures come from the Library of Congress country study's summary of the competing estimates by Denevan and Hemming, and the Tupi peoples' role as the first met by the Portuguese is documented in both the country study and Brown University's Brazil: Five Centuries of Change.
Denevan estimate: 3,625,000 in the Amazon Basin, 4,800,000 elsewhere · Hemming estimate: 2,431,000 for Brazil as a whole · Major language families: Ge, Tupi, Carib, Arawak, plus Nambicuara · First met by Portuguese: Tupi speakers of the coast

Pedro Alvares Cabral left Lisbon in March 1500 leading a fleet bound for India along Vasco da Gama's route. Sailing far southwest into the Atlantic to catch favorable winds, he reached an unknown coastline instead, anchored, and claimed the land for Portugal before continuing to India. World History Encyclopedia notes he 'sailed too far west and accidentally discovered Brazil' with 1,200 Portuguese aboard after badly missing his intended destination near southern Africa. The land fell on Portugal's side of the line drawn by the 1494 Treaty of Tordesillas, which is why Brazil would speak Portuguese rather than Spanish.
Why it matters: Cabral's landfall opened three centuries of Portuguese rule and set the language, religion, and colonial economy of the largest country in South America. This timeline treats the landing itself briefly; the fuller account of the voyage, the fleet, and the Tordesillas line sits in the Age of Exploration timeline.
How we know: The accidental landfall and the claim for Portugal are documented in World History Encyclopedia's Portuguese Brazil article and in the Mariners' Museum Ages of Exploration entry on Cabral, both fetched and confirmed.

The domain "library.brown.edu" is on our Reputable source registry.Brazilwood Gives the Colony Its Name
The first thing Portugal wanted from its new land was a tree. Brazilwood, prized in Europe for its wood and a red dye it produced, grew in abundance along the Atlantic coast. When the Portuguese saw the blood-red inside of these trees, they called them pau-brasil, pau being Portuguese for 'wood' and brasil a derivative of brasa, or ember. The name Brazil first appears on maps around 1511. Harvesting the wood required Indigenous labor, and the Tupi people, initially traded with for that labor, were increasingly coerced or enslaved as demand grew. From 1504 onward, French vessels from Brittany, Flanders, and Normandy competed in the dyewood trade despite Portugal's claimed monopoly.
Why it matters: Brazilwood set the pattern for everything that followed: a single high-value export, extracted from the land, worked by forced Indigenous labor, and defended against European rivals. When the coastal brazilwood stands were cut out, the same colonists replaced them with sugarcane, carrying the extractive logic forward into a far larger and deadlier system.
How we know: The etymology of the name and the tree's role as a chief early export are documented verbatim in Brown University's Brazil: Five Centuries of Change, and the French competition in the dyewood trade from 1504 is recorded in the Library of Congress country study.

The domain "worldhistory.org" is on our Reputable source registry.The Crown Divides Brazil Into Captaincies
To settle a coast it could not afford to garrison directly, the Portuguese Crown carved Brazil into feudal grants called captaincies. World History Encyclopedia records 15 such grants, obliging the nobles who received them, or more accurately their vassals, to develop the land for agriculture. Under the system, as the Library of Congress country study puts it, each donee was responsible for colonizing his own captaincy at his own expense. Most captaincies failed. The Crown then shifted toward direct royal administration, sending Tome de Sousa to found a capital city, Salvador, on the Bay of All Saints (Baia de Todos os Santos) in 1549.
Why it matters: The captaincy system was Portugal's low-cost gamble on colonization, and its failure pushed the Crown to build a centralized colonial government at Salvador that would run Brazil for over two centuries. The two captaincies that did succeed, both sugar-growing, pointed the way to the crop that would define colonial Brazil and its demand for enslaved labor.
How we know: The number of captaincies and the donatary obligations are documented in World History Encyclopedia and the Library of Congress country study, which also records the royal order to establish the capital at Salvador.
Number of grants: 15 hereditary captaincies · Obligation: Colonize at the donee's own expense · First capital: Salvador, Bay of All Saints, founded 1549 · Outcome: Most captaincies failed; Crown took direct control

As the coastal brazilwood was cut out, colonists replaced it with sugarcane. The plantation and mill complex, the engenho, spread fast: the Library of Congress country study records that by 1585 the sugar zones were served by more than sixty mills. World History Encyclopedia states that within a few decades Brazil had become the world's largest producer of sugar, with 60 mills in 1570 rising to 350 by 1645. Sugar was capital-intensive and brutally labor-hungry, and colonists turned first to enslaved Indigenous people and then, as those populations collapsed, increasingly to enslaved Africans.
Why it matters: Sugar transformed Brazil from a coastal trading post into a plantation economy and made it the engine of Portugal's empire. Its appetite for labor is the direct cause of the Atlantic slave trade to Brazil, which would bring more enslaved Africans to this one colony than to any other destination in the Americas.
How we know: The mill counts and Brazil's status as the world's largest sugar producer are documented verbatim in World History Encyclopedia and the Library of Congress country study, drawing on colonial economic records.
Mills in 1570: 60 engenhos · Mills by 1645: 350 engenhos · Rank: World's largest sugar producer within decades · Labor: Enslaved Indigenous, then enslaved African

Brazil received more enslaved Africans than anywhere else in the Americas. Yale University Press states that Portuguese America, Brazil after 1822, received almost five million enslaved Africans between 1501 and 1866. The U.S. National Park Service records that from 1560 to 1850, about 4.8 million enslaved people were transported to Brazil, more than the roughly 4.7 million sent to the Caribbean and vastly more than the fewer than 400,000 carried to North America. The SlaveVoyages database credits the Portugal and Brazil carrier flag with 5,848,266 of the 12,521,337 Africans embarked across the entire trade. Mortality on the crossing, on the plantations, and in the mines was enormous, and even after Brazil's own laws banned the traffic, Yale University Press notes almost one million more individuals were carried into the country illegally in one of the greatest crimes of the nineteenth century.
Why it matters: The scale is the point. Sugar, then gold, then coffee were all built on the forced labor of enslaved Africans, and Brazil's share of the trade, close to 40 to 46 percent of all arrivals in the Americas by most estimates, shaped the country's population, culture, and inequality more than any other single fact of its history.
How we know: The near-five-million figure is stated verbatim by Yale University Press and corroborated by the U.S. National Park Service's Middle Passage article; the carrier-flag totals are read directly from the SlaveVoyages estimates database, whose aggregate tables are treated as estimates rather than exact counts.

Portugal's richest colony drew rivals. The Dutch West India Company, formed in 1621 to trade, plunder, and build American colonies, captured Salvador in 1624 but held it only a year. In 1630 the Dutch grabbed Olinda and Recife, took Pernambuco in 1632, and occupied northern Brazil by 1635, running the region's sugar economy for themselves. Portugal, determined to protect the best asset of its empire, sent an armada of 41 ships and 5,000 men in 1638, but did not regain full control of Brazil until 1654.
Why it matters: Dutch Brazil was the most serious foreign challenge to Portuguese rule in the colony's history, and the long war to expel the Dutch drained the sugar economy at the same moment Caribbean rivals were learning the plantation techniques the Dutch had studied in Pernambuco. When the Dutch left, they carried that expertise to the Caribbean, seeding the competition that would eventually undercut Brazilian sugar.
How we know: The sequence of Dutch conquests from 1624 to 1635 and the Portuguese reconquest completed in 1654 are documented verbatim in World History Encyclopedia's Portuguese Brazil article, drawing on the records of the Dutch West India Company period.

The discovery of gold by Paulistas, the frontier explorers known as bandeirantes, in various parts of what is now Minas Gerais probably occurred between 1693 and 1695, though word spread slowly at first. Then the rush came. By 1709 some 30,000 people were in Minas Gerais, and by 1735 tax records showed 100,141 slaves in the mining district, many of them Indigenous. World History Encyclopedia records that by 1711 the annual amount of Brazilian gold legally shipped to Portugal had risen to almost 15,000 kilograms, later peaking above 30,000 kilograms a year. The boom drew population and wealth from the coast into the interior and made Rio de Janeiro, the nearest port, the colony's new center of gravity.
Why it matters: Gold shifted colonial Brazil's economy and geography away from the northeastern sugar coast toward the southeastern interior and Rio de Janeiro, which became the colonial capital in 1763. The mining economy, like the sugar economy before it, ran on enslaved labor, and the taxes Portugal levied on Brazilian gold would later fuel colonial resentment.
How we know: The dates of discovery, the population and slave figures for Minas Gerais, and the volume of gold shipped to Portugal are documented verbatim in the Library of Congress country study and World History Encyclopedia.
Gold discovered: Between 1693 and 1695, by Paulista bandeirantes · Minas Gerais population by 1709: About 30,000 people · Enslaved people by 1735: 100,141 (tax records) · Gold to Portugal by 1711: Almost 15,000 kg a year

As the French army approached Lisbon in November 1807, the Portuguese Crown faced a choice between losing Portugal to the French and having the British seize Brazil, or moving the crown to Brazil. It chose to sail. Prince Regent Dom Joao, ruling for his incapacitated mother, evacuated the royal family and some 15,000 courtiers to Rio de Janeiro under British naval protection, arriving in 1808. The colony suddenly became the seat of a European monarchy. In 1815 the Crown raised Brazil to a kingdom equal with Portugal, and when the old queen died in 1816, Joao was acclaimed King Joao VI.
Why it matters: No other European power ever relocated its entire government to a colony. The court's presence gave Rio de Janeiro a royal treasury, a printing press, banks, and institutions no colony was normally allowed, and it made the eventual break with Portugal almost bloodless: when Joao VI sailed home in 1821, he left his son Pedro behind as regent, and independence followed within a year.

After King Joao VI returned to Lisbon in 1821, the Portuguese parliament tried to reduce Brazil back to colonial status and recall his son, Prince Pedro. Pedro refused. In a famous scene at Ipiranga on September 7, 1822, the Library of Congress country study records, he had to choose between returning to Portugal in disgrace or opting for independence, and he chose independence: his motto, he said, would be Independence or Death. Pedro had already declared himself perpetual defender of Brazil in May. He was crowned Pedro I, first Emperor of Brazil, and Britain and Portugal recognized Brazilian independence by treaty on August 29, 1825.
Why it matters: Brazil became independent as a monarchy, not a republic, and did so with almost no war, sparing it the fragmentation that broke Spanish America into many states. A single prince of the Portuguese royal house crowning himself emperor of a New World country is one of the most unusual paths to independence in the Americas, and it kept Brazil territorially whole.
How we know: The Ipiranga declaration, the Independence or Death motto, and the 1825 recognition treaty are documented verbatim in the Library of Congress country study, with Pedro's status as first Emperor of Brazil confirmed in World History Encyclopedia.

Pedro I abdicated in 1831 and left for Portugal, leaving his young son as heir under a regency. Pedro I's death from tuberculosis in 1834 sapped the movement to restore him, and the regency years were unstable. To end the turmoil, politicians declared the boy-emperor of age early: he ascended the throne on July 18, 1841, at age fifteen instead of the constitutionally specified age of eighteen. Thus, the Library of Congress country study records, the second empire was born, in the hope that it would be an instrument of national unity, peace, and prosperity. Pedro II would reign for nearly fifty years, using his constitutional moderating power to balance liberal and conservative cabinets.
Why it matters: Pedro II's long reign gave Brazil rare stability in a century when its Spanish-speaking neighbors cycled through coups and civil wars. The empire held a continent-sized territory together under one government, and Pedro II's personal support for gradual abolition shaped the slow legal end of slavery that culminated in 1888.
How we know: The early declaration of Pedro II's majority in 1841 and the birth of the second empire are documented verbatim in the Library of Congress country study.

The domain "worldhistory.org" is on our Reputable source registry.Coffee Becomes the Engine of the Empire
As sugar declined, coffee rose to take its place. The Library of Congress country study records that coffee dominated exports in the last half of the nineteenth century, going from 50 percent of exports in 1841-50 to 59.5 percent in 1871-80. The coffee zone lay in the southeast, in the Paraiba Valley and the highlands of Sao Paulo and Minas Gerais, and its plantations were worked at first by enslaved Africans and later by waves of European immigrants. Coffee wealth built railroads, ports, and the fortunes of a new planter elite centered on Sao Paulo.
Why it matters: Coffee shifted Brazil's economic and political center of gravity firmly to the southeast and created the Paulista planter class that would dominate national politics for decades after the empire fell. The same coffee economy that enriched Sao Paulo also depended on slavery until 1888 and on cheap immigrant labor afterward, tying Brazil's export boom directly to its two great labor systems.
How we know: The share of coffee in Brazilian exports across the mid and late nineteenth century is documented verbatim in the Library of Congress country study, drawing on imperial trade statistics.
Coffee share of exports, 1841-50: 50 percent · Coffee share of exports, 1871-80: 59.5 percent · Coffee region: Southeast: Sao Paulo, Minas Gerais, Paraiba Valley · Labor: Enslaved Africans, then European immigrants

Brazil ended slavery in stages. The 1871 Law of Free Birth freed children born to enslaved mothers going forward, and the 1885 Sexagenarian Law freed the enslaved once they reached age sixty, but neither freed anyone already enslaved and of working age. On May 13, 1888, Princess Isabel, serving as regent while Emperor Pedro II was in Europe, signed the Lei Aurea, the Golden Law, abolishing slavery outright. The Library of Congress country study frames it bluntly: the Golden Law was not an act of great bravery but a recognition that slavery was no longer viable. Brazil, which had received nearly five million enslaved Africans, was the last country in the Americas to abolish slavery, and the law came with no land, no compensation, and no support for the roughly 700,000 people it freed.
Why it matters: Abolition closed the longest and largest slave system in the Americas, and its total absence of support for the freed population, no land, no wages owed, no path to schooling or citizenship, is why historians describe Brazilian abolition as a legal ending without an economic or social one, a pattern that shaped Brazilian inequality for generations. The empire that had leaned on slavery collapsed within eighteen months of ending it.
How we know: The Golden Law and its framing are documented verbatim in the Library of Congress country study and Brown University's Brazil: Five Centuries of Change, with Brazil's status as the largest slave destination corroborated by Yale University Press.

Eighteen months after abolition, the empire fell. The Library of Congress country study records that republicans, taking advantage of cabinet crises in 1888 and 1889 and rising frustration among military officers, drew officers led by Field Marshal Deodoro da Fonseca into a conspiracy. What started as an armed demonstration demanding replacement of a cabinet turned within hours into a coup d'etat deposing Emperor Pedro II, in November 1889. The coup met no resistance. Pedro II went into exile in Europe, a provisional government took power with Fonseca as its head, and Brazil became a republic on November 15, 1889.
Why it matters: The abolition of slavery had stripped the monarchy of its last powerful backers, the slaveholding planters, and the army, newly confident after the Paraguayan War, filled the vacuum. The Republic that replaced the empire would be dominated for four decades by the coffee oligarchies of Sao Paulo and Minas Gerais rather than by the broad citizenry its founders invoked.
How we know: The military conspiracy and the one-day coup deposing Pedro II are documented verbatim in the Library of Congress country study, with the date and Fonseca's leadership confirmed by contemporary accounts of the proclamation.

The First Republic, later nicknamed the Republica Velha, was an oligarchy dressed as a democracy. Real power resided in the coffee-growing states of the southeast, and the populous, prosperous states of Minas Gerais and Sao Paulo dominated the system and swapped the presidency between them for many years, an arrangement remembered as cafe com leite, coffee with milk, after Sao Paulo's coffee and Minas Gerais's dairy. Beneath it ran coronelismo, a web of unwritten agreements among local bosses, the colonels, who delivered votes and chose governors. At its height Brazil produced 75 percent of the world's coffee, and falling prices pushed the government to prop up the market and devalue the currency.
Why it matters: The cafe com leite system concentrated national power in two states and a single crop, and its rigidity is what cracked in 1930 when a disputed election and the collapse of coffee prices during the Great Depression let Getulio Vargas sweep the old order aside. The Republic's narrow base of power left most Brazilians, urban workers and the rural poor, without a real voice.

The Great Depression gutted coffee prices, and the 1930 presidential election, seen by opponents as rigged for Sao Paulo's candidate, gave the losing coalition a cause. A revolt swept the country, and Getulio Dorneles Vargas, governor of Rio Grande do Sul, took national power. Brown University's Brazil: Five Centuries of Change records that the disintegration of the old political order gave rise to the triumph of Getulio Vargas in the Revolution of 1930, which instituted a swing towards centralization of power in the federal government. The Library of Congress country study notes that Vargas then ruled as dictator from 1930 to 1934 in a provisional government before a brief constitutional period.
Why it matters: The Revolution of 1930 ended the coffee oligarchy's monopoly on national power and began the fifteen-year Vargas era that reshaped the Brazilian state, centralizing authority, building industry, and creating labor laws that still frame Brazilian politics. It is the hinge between the rural, oligarchic Old Republic and the modern, centralized, industrializing Brazil that followed.

In November 1937, weeks before a scheduled election he was barred from contesting, Vargas staged a self-coup, issued a new authoritarian constitution, and declared the Estado Novo, the New State. Brown University's Brazil: Five Centuries of Change records that Vargas created a dictatorial regime with his establishment of the Estado Novo. The Library of Congress country study describes what changed: under the Estado Novo, state autonomy ended, appointed federal officials replaced governors, and patronage flowed from the president downward, while all political parties were dissolved until 1944, limiting any organized opposition. The regime censored the press, jailed opponents, and built a corporatist state that also expanded labor rights and industry.
Why it matters: The Estado Novo was Brazil's first modern dictatorship, a nationalist, centralizing, corporatist regime that broke the power of the states and built the federal institutions and labor codes that outlasted Vargas himself. It also showed the pattern Brazil would repeat in 1964: a constitutional order suspended in the name of order and anti-communism, with real repression underneath the modernizing rhetoric.
How we know: The establishment of the Estado Novo as a dictatorial regime is documented verbatim in Brown University's Brazil: Five Centuries of Change, and its dissolution of the states and parties in the Library of Congress country study.

Vargas, courted by both the Axis and the Allies, joined the Allied side and sent the Brazilian Expeditionary Force, the Forca Expedicionaria Brasileira, to fight in Italy. History.com records that Brazil was the only South American nation and one of just two Latin American countries to take up arms, deploying a 25,000-man force nicknamed the Smoking Snakes. The Brazilian government's own account puts the force at 25,900 men and credits it with a legendary victory at the Battle of Monte Castello in early 1945. The BEF landed at Naples in mid-1944, first saw hostile fire in September 1944, and fought through the war's end in May 1945.
Why it matters: Brazil was the only South American country to put ground troops into the European theater, and the army's prestige from the Italian campaign reshaped domestic politics: the popular status the army won by participating in the campaign, the Library of Congress country study notes, is part of what let the High Command move against Vargas himself in 1945. The contradiction of a dictatorship sending soldiers to fight fascism abroad helped undo the Estado Novo at home.

Juscelino Kubitschek, elected in 1955 on the slogan Fifty Years' Progress in Five, made his signature project the construction of a wholly new capital in the empty central highlands. The Library of Congress country study records that he yanked Brazil away from its fascination with the coast by moving the capital to Brasilia in a new Federal District carved out of then-distant Goias. Planned by Lucio Costa and designed by architect Oscar Niemeyer, the city was built in about four years and inaugurated on April 21, 1960, replacing Rio de Janeiro as the seat of government.
Why it matters: Brasilia was a deliberate act of nation-building, an attempt to pull Brazil's population and development inland after four centuries of hugging the coast, and it became a global emblem of modernist architecture and mid-century optimism. Its enormous cost also fed the inflation and political strain that helped destabilize the democratic governments of the early 1960s.
How we know: Kubitschek's relocation of the capital to Brasilia is documented verbatim in the Library of Congress country study and Brown University's Brazil: Five Centuries of Change; the April 21, 1960 inauguration date is the well-established public record confirmed by multiple institutional accounts.

Brazil's Second Republic died in a coup. Amid economic crisis, high inflation, and elite fears of communism, President Joao Goulart, a populist and former labor minister under Vargas, lost the confidence of the military and the coffee and business classes. In late March 1964 the armed forces moved. The Library of Congress country study records that the military moved to secure the country and Goulart fled to Uruguay. The generals took power on April 1, 1964, and would hold it, the country study notes, from 1964 until March 1985, not by original design but because of political struggles within the new regime.
Why it matters: The 1964 coup began a 21-year military dictatorship, part of a wave of Cold War military governments across South America, and it set the pattern of censorship, torture, and disappearances that a later national commission would document. It also ended the democratic experiment begun in 1945 and delayed Brazil's return to civilian rule for a generation.
How we know: Goulart's flight and the military's seizure of the country are documented verbatim in the Library of Congress country study, which also dates the regime from 1964 to March 1985.

The dictatorship hardened. On December 13, 1968, hard-liners in the military pressured President Costa e Silva into promulgating the Fifth Institutional Act, known as AI-5. The Library of Congress country study describes its effect: the act gave the president dictatorial powers, dissolved Congress and state legislatures, suspended the constitution, and imposed censorship. What followed were the years of heaviest repression. The country study records that the repressive apparatus expanded into various agencies, which spied on political opponents and engaged in dirty tricks, torture, and disappearings, alongside an antiguerrilla campaign against armed opposition groups.
Why it matters: AI-5 marks the point where Brazil's military government dropped even the pretense of legality and became a full police state, and the torture and disappearances of these years, the anos de chumbo or years of lead, are what the 2014 National Truth Commission would later investigate. It is the concrete evidence that the regime's later economic miracle was built alongside systematic state violence.
How we know: The provisions of AI-5 and the expansion of the repressive apparatus into torture and disappearances are documented verbatim in the Library of Congress country study.
Decree: Fifth Institutional Act (AI-5) · Date: December 13, 1968 · Powers: Dissolved Congress, suspended the constitution, imposed censorship · Methods: Torture, disappearings, surveillance

The domain "library.brown.edu" is on our Reputable source registry.Brazil Returns to Civilian Rule
The dictatorship ended gradually through a controlled opening the generals called abertura. On January 15, 1985, the Library of Congress country study records, the electoral college elected Tancredo Neves of Minas Gerais, a civilian opposition leader, as president, ending 21 years of military rule. Neves collapsed the night before his inauguration and died weeks later, and the presidency passed to Vice President Jose Sarney. A new democratic constitution followed in 1988, restoring direct elections, civil liberties, and the political rights the dictatorship had suspended.
Why it matters: The 1985 transition returned Brazil to civilian government and led directly to the 1988 constitution that still governs the country, ending the longest authoritarian period since Vargas. That the handover came through an indirect electoral college rather than a popular vote, and that the amnesty protecting the regime's torturers stayed in place, shaped the compromises of Brazil's new democracy.
How we know: The January 15, 1985 election of Tancredo Neves, his collapse before inauguration, and the succession of Jose Sarney are documented verbatim in the Library of Congress country study.

Democratic Brazil's first great achievement was killing inflation. Prices had spiraled for years, reaching 757 percent in just the first half of 1994. The Plano Real, launched under President Itamar Franco with Fernando Henrique Cardoso as finance minister, used a virtual accounting currency, the Unidade Real de Valor, to reset expectations before introducing a new money. The Brazilian government's news service records that on July 1, 1994, a new currency was brought into force in Brazil: the real, putting an end to the hyperinflation, after which inflation plummeted to 18.6 percent in the following half-year. Cardoso rode the plan's success to the presidency in 1995 and served two terms.
Why it matters: Hyperinflation had punished Brazil's poor hardest and made stable planning impossible; ending it stabilized the economy and lifted incomes, and it reshaped politics by carrying Cardoso to the presidency and setting the stage for the social programs of the governments that followed. The Real Plan is the economic foundation of the modern Brazilian state.
How we know: The July 1, 1994 launch of the real, the pre-plan inflation of 757 percent, and the drop that followed are documented verbatim across two reports from Brazil's official Agencia Brasil news service.
Launched: July 1, 1994 (new currency, the real) · Inflation before: 757 percent in the first half of 1994 · Inflation after: 18.6 percent in the following half-year · Architect: Finance Minister Fernando Henrique Cardoso

Decades after the fact, Brazil counted its dead. The National Truth Commission, reporting on December 10, 2014, raised the confirmed toll of the dictatorship years. Human Rights Watch records that the commission increased the count of people dead or disappeared during the Dirty War years to 434, whereas the official number previously stood at 362, a total made up of 191 people killed, 210 disappeared, and 33 who were disappeared but whose bodies were later recovered. The report identified hundreds of individuals responsible for human rights violations, close to 200 of them still alive, and found the abuses were widespread and systematic actions carried out as government policy. These are confirmed cases; historians and victims' groups regard the real toll, including Indigenous deaths and unregistered victims, as higher.
Why it matters: The commission gave Brazil an official, documented account of state killings, torture, and disappearances under the military regime, ending decades of official silence. That the confirmed figure of 434 is treated as a floor, not a ceiling, reflects how much of the repression left no paper trail, and the report's finding that the crimes were deliberate government policy is why it has fueled continuing debate over the 1979 amnesty that shielded the perpetrators.
How we know: The commission's figures of 434 dead or disappeared and its finding of systematic, government-directed abuse are documented verbatim by Human Rights Watch, corroborated by the Library of Congress country study's account of the regime's use of torture and disappearances.
Report date: December 10, 2014 · Confirmed dead or disappeared: 434 (191 killed, 210 disappeared, 33 later recovered) · Previous official count: 362 · Finding: Widespread, systematic, government policy
