History of Rio de Janeiro: A Visitor's Timeline
Written and reviewed by Lotte — Rio local, founder & editor of PlanRio · How we research · First published · Last reviewed
The Arcos da Lapa carried Rio's drinking water down from Santa Teresa from the eighteenth century; since 1896 they have carried the tram.
Quick answer
Rio was named on 1 January 1502 by Portuguese sailors who mistook Guanabara Bay for a river, founded in 1565 to expel a French colony, made Brazil's capital in 1763, and governed the Portuguese Empire from 1808 to 1821. It was the largest slave port in the Americas and lost the capital to Brasília in 1960.

1502: a bay mistaken for a river
A Portuguese expedition sailed into Guanabara Bay on or around 1 January 1502 and concluded, reasonably enough given the narrow entrance between Sugarloaf and the Niterói headland, that they had found the mouth of a great river. They named it for the month: Rio de Janeiro, River of January. There is no river. The name has survived five centuries of people pointing this out.
What they had actually found was one of the great natural harbours on earth, surrounded by Tupi-speaking Tupinambá peoples who had lived around the bay for far longer than any European record. For the next sixty years nothing much was built: the Portuguese traded brazilwood along the coast and did not settle the bay.
You can still read the geography that caused the mistake from the top of Sugarloaf, which is the single most useful first stop for understanding this city’s history — the bay mouth, the Niterói side, the beaches and the hills are all legible at once.
1555–1567: the city exists because France got there first
In 1555 a French expedition under Nicolas Durand de Villegagnon established France Antarctique in the bay, on the island that still carries his name — Ilha de Villegagnon, now the Naval Academy, visible from Flamengo. It was a Huguenot and Catholic settlement, allied with the Tamoio peoples, and it was a direct strategic threat to Portuguese Brazil.
The Portuguese response founded Rio. Estácio de Sá landed in 1565 at the foot of Morro Cara de Cão, in what is now Urca between Sugarloaf and Praia Vermelha, and established São Sebastião do Rio de Janeiro as a military position. He was killed in the fighting. His uncle Mem de Sá completed the expulsion of the French in 1567, and the settlement was moved to the more defensible Morro do Castelo in what is now Centro.
This is why Rio’s founding site is not in Centro. The city began as a fort on the bay mouth, in the neighbourhood that is now the quietest and most residential corner of the Zona Sul — our Urca guide covers what survives there, including Praia Vermelha and the fortifications.
1763: gold moves the capital south
For two centuries Brazil's capital was Salvador, because the economy was sugar and the sugar was in the Northeast. Then gold and diamonds were found in Minas Gerais, and the shortest route from the mines to the Atlantic ran through Rio. The port grew on other people's gold, and in 1763 the colonial capital was transferred from Salvador to Rio de Janeiro.
The physical legacy of this period is the water supply. Colonial Rio had no reliable fresh water in the lower town, so between the late seventeenth and mid-eighteenth centuries the Carioca Aqueduct was built to carry water down from the Santa Teresa hills to a public fountain in the centre. It is the double-tiered arcade in Lapa that everybody photographs, and since 1896 it has carried the Santa Teresa tram rather than water.
It is also where the word carioca comes into focus: the Carioca river, the aqueduct named for it, and eventually the people. Our what is a carioca page unpicks the etymology, and the Santa Teresa tram still crosses the arches.
1808: the only European court to govern from the Americas
In November 1807 Napoleon's army marched on Lisbon. The Portuguese court did not fall; it left. Around ten to fifteen thousand people — the Prince Regent João, the royal family, the government, the treasury, the archives and much of the aristocracy — crossed the Atlantic under British naval escort and arrived in Rio in March 1808. For the next thirteen years, the Portuguese Empire was administered from Rio de Janeiro. It remains the only instance of a European power being governed from its colony.
The city was transformed in a decade because it had to be. The ports were opened to foreign trade, ending the colonial monopoly. A royal press, a military academy, a medical school, a bank and the Royal Library were founded. The Jardim Botânico was established in 1808 to acclimatise plants from across the empire; its avenue of royal palms descends from a single tree planted in that decade. In 1815 Brazil was elevated from colony to kingdom within a United Kingdom of Portugal, Brazil and the Algarves.
When João VI returned to Lisbon in 1821 he left his son Pedro behind, and the following year Pedro declared independence and had himself crowned emperor. Rio stayed the capital of the Empire of Brazil until the monarchy fell in 1889. Almost everything grand in Centro — the Paço Imperial, the Theatro Municipal, the Real Gabinete Português de Leitura — belongs to this imperial century, as does the imperial summer capital at Petrópolis.
Valongo: the fact the rest of the history sits on
Rio was the largest slave port in the history of the Atlantic trade. The Cais do Valongo, a stone wharf in what is now the port district, operated between 1774 and 1843 and received on the order of one million enslaved Africans — the single largest point of arrival of enslaved people anywhere in the Americas. UNESCO, inscribing it as a World Heritage Site in 2017, called it the most important physical trace of the transatlantic slave trade on the American continent.
The wharf was deliberately buried in 1843, paved over to receive the Empress Teresa Cristina, and stayed buried for nearly 170 years. It was rediscovered in 2011 when the Porto Maravilha redevelopment dug up the area ahead of the Olympics. That sequence — built, used, buried for a royal arrival, forgotten, found by accident during a sports regeneration project — is the clearest single illustration of how this history has been handled.
Brazil abolished slavery on 13 May 1888, later than any other country in the Americas, and without land, compensation or provision of any kind for the people freed. The direct consequence is the shape of the city: the hills were settled because there was nowhere else to go. The Little Africa walking guide covers Valongo, Pedra do Sal and the port district on foot, and what is a favela picks up what happened next.
1889–1922: the republic demolishes the colonial city
The monarchy was overthrown in 1889 and the new republic set about making Rio look like Paris. Between 1903 and 1906, mayor Francisco Pereira Passos drove a programme of demolition and boulevard-building through the dense colonial centre: Avenida Central — today Avenida Rio Branco — was cut through, hundreds of tenements were cleared, and tens of thousands of poor residents were displaced to the hills and the periphery.
It was also a public-health campaign, and it produced the Revolta da Vacina of November 1904, a week of street fighting touched off by compulsory smallpox vaccination carried out by sanitary brigades entering homes by force. The revolt is a useful corrective to the tidy story of modernisation: the reforms that produced the beautiful Centro were imposed, and they were resisted.
The demolition peaked in 1922, when Morro do Castelo — the hill the city had moved to in 1567, by then a crowded working-class district — was levelled entirely to make room for the centenary exposition and to let sea breezes into the centre. The city removed its own founding site. The flat ground around Praça Mauá and the Castelo esplanade is where a hill used to be.
1950 and 1960: a stadium, and the loss of the capital
The Maracanã was built for the 1950 World Cup, and on 16 July 1950 Brazil lost the deciding match to Uruguay in front of a crowd officially recorded near 174,000 and widely estimated closer to 200,000 — still the largest attendance at a football match. The Maracanazo is not a sporting footnote here; it is a national reference point, invoked in Brazilian conversation to this day.
Ten years later the city lost its reason for being a capital. Brasília was inaugurated on 21 April 1960 and the federal government moved inland. Rio was reconstituted as a city-state, the State of Guanabara, and governed separately until 15 March 1975, when it was merged with the surrounding state of Rio de Janeiro and became its capital instead. The loss of federal status, the departure of the civil service and the slow economic decline that followed shaped the second half of the twentieth century here.
What Rio kept was culture. Bossa nova came out of Ipanema and Copacabana apartments in the late 1950s; samba had been organised into competing schools and a formal parade since the 1930s; the beach became the city’s public square. See the bossa nova guide and Rio beach culture for how both still work.
2012–2016 and after: heritage, Olympics, and the port again
In 2012 UNESCO inscribed “Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea” on the World Heritage List — the first city anywhere to be listed as an urban cultural landscape, recognising the relationship between the built city, the Tijuca forest, the bay and the Atlantic rather than any single monument.
Then came the 2014 World Cup and the 2016 Olympics, and with them the Porto Maravilha regeneration of the derelict port: the Museu do Amanhã opened in 2015, the Museu de Arte do Rio and the Boulevard Olímpico followed, an elevated motorway was demolished, and Valongo came out of the ground. The verdict on all of it is genuinely mixed — some of the venues decayed, some of the promises (notably the cleaning of Guanabara Bay) were not met, and the city entered a fiscal crisis immediately afterwards.
That mixed verdict is itself worth seeing. Our Museu do Amanhã guide and MAR guide cover the successes; the crime data and the bay’s water quality cover what did not change.
How to see five centuries in two days
Day one, the bay and the empire. Start at Praia Vermelha and Morro Cara de Cão in Urca, where the city was founded in 1565, then go up Sugarloaf for the geography that caused the 1502 naming. Afternoon in Centro: the Paço Imperial on Praça XV, the Theatro Municipal, the Real Gabinete, and a walk up to the Carioca Aqueduct in Lapa at dusk.
Day two, the port and the twentieth century. Morning in the port district: Cais do Valongo, Pedra do Sal, the Museu de Arte do Rio and the Museu do Amanhã, ideally with a Little Africa walking guide. Afternoon at the Maracanã, or up to Santa Teresa by tram to see the hillside the aqueduct drew water from — and the neighbourhood the 1904–1922 demolitions pushed people towards.
If you would rather have this narrated than assembled, a guided historic-Centro walk covers the imperial and republican layers in half a day, and a wider city tour adds the geography. Both are below, and our architecture guide and historic churches walk go deeper on the buildings this timeline passes through.

Common mistakes tourists make
- Looking for the river. There isn't one — the name records a 1502 navigational error about the bay entrance.
- Assuming Rio was founded in Centro. It began as a fort in Urca, at the foot of Morro Cara de Cão.
- Treating Rio as Brazil's historic capital throughout. Salvador held it until 1763 and Brasília took it in 1960.
- Thinking the grand Centro is colonial. Most of what you photograph is imperial (1808–1889) or belle-époque (1903–1906).
- Skipping the port district. Valongo is the most historically significant site in the city and most visitors never reach it.
- Reading the Pereira Passos reforms as straightforward progress — they displaced tens of thousands and triggered the 1904 Vaccine Revolt.
- Assuming the 2016 Olympic regeneration is the whole story of the port. It is also how Valongo came back out of the ground.
Local expert tips
- Do Sugarloaf first, whatever your itinerary. The geography explains almost every decision in this timeline.
- The Carioca Aqueduct is a water-supply engineering project that happens to carry a tram — read it as infrastructure, not decoration.
- Praça XV is the single densest historical square in the city: the Paço Imperial, the ferry terminal and Ilha Fiscal in one view.
- Pair Valongo with Pedra do Sal and MAR in one morning; separately they are fragments, together they are the port's history.
- The Jardim Botânico's royal palms descend from trees planted in 1808 — that avenue is a living piece of the Portuguese court.
- If you only have one history half-day, make it the port district rather than Centro. It is less visited and more consequential.
Frequently asked questions
Why is Rio de Janeiro called Rio de Janeiro?+
It means “River of January”. A Portuguese expedition entered Guanabara Bay on or around 1 January 1502 and mistook the narrow bay entrance for the mouth of a large river, naming it for the month of arrival. There is no river — the name records a five-century-old navigational error.
When was Rio de Janeiro founded?+
1 March 1565, as São Sebastião do Rio de Janeiro, by Estácio de Sá — and specifically in order to expel a French colony, France Antarctique, established in the bay in 1555. The original site was at Morro Cara de Cão in what is now Urca; the settlement moved to Morro do Castelo in Centro after the French were driven out in 1567.
Was Rio de Janeiro the capital of Portugal?+
Yes, from 1808 to 1821. When Napoleon's army advanced on Lisbon in 1807, the Portuguese court crossed the Atlantic under British escort and governed the Portuguese Empire from Rio. It is the only case in history of a European empire being administered from the Americas. Brazil was raised from colony to kingdom in 1815 and became independent in 1822.
How long was Rio de Janeiro the capital of Brazil?+
Nearly two centuries — from 1763, when the colonial capital moved from Salvador because of the Minas Gerais gold trade, until 21 April 1960, when Brasília was inaugurated. Rio was then governed separately as the State of Guanabara until 15 March 1975, when it merged with the surrounding state and became its capital.
What is Cais do Valongo?+
A stone wharf in Rio's port district that operated between 1774 and 1843 and received on the order of one million enslaved Africans — the largest single point of arrival of enslaved people in the Americas. It was buried in 1843 ahead of Empress Teresa Cristina's arrival, rediscovered in 2011 during the Porto Maravilha works, and inscribed by UNESCO in 2017 as the most important physical trace of the transatlantic slave trade on the continent.
What was the Revolta da Vacina?+
A week of street fighting in Rio in November 1904, triggered by a compulsory smallpox vaccination campaign in which sanitary brigades entered homes by force. It coincided with mayor Pereira Passos's demolition of the colonial centre to build Avenida Central, and it is the standard reminder that Rio's belle-époque modernisation was imposed on the city's poor rather than agreed with them.
Why was Morro do Castelo demolished?+
The hill the city had moved to in 1567 was levelled entirely in 1922, officially to improve ventilation and public health in the centre and to clear ground for the independence centenary exposition. By then it was a crowded working-class district, and its residents were displaced. Rio removed its own founding hill; the flat esplanade near Praça Mauá is where it stood.
Why is Rio de Janeiro a UNESCO World Heritage Site?+
Rio was inscribed in 2012 as “Carioca Landscapes between the Mountain and the Sea” — the first city ever listed under the Cultural Landscape criteria. The listing recognises the interaction between the built city and its setting: the Tijuca forest, Corcovado, Sugarloaf, Guanabara Bay and the beaches, together with the historic centre. Cais do Valongo was separately inscribed in 2017.
What happened at the Maracanã in 1950?+
Brazil lost the deciding match of its own World Cup to Uruguay on 16 July 1950, in front of a crowd officially recorded near 174,000 and widely estimated closer to 200,000 — still the largest attendance at a football match. The Maracanazo remains a national reference point in Brazil, invoked far beyond sport.
Where can I see Rio's history on a short trip?+
Urca and Sugarloaf for the 1502 naming and the 1565 founding; Praça XV, the Paço Imperial, the Theatro Municipal and the Real Gabinete for the imperial century; the Carioca Aqueduct and the Santa Teresa tram for colonial water supply; Cais do Valongo, Pedra do Sal and MAR for the port and the slave trade; and the Maracanã and the Boulevard Olímpico for the twentieth century. Two full days covers all of it.
