Events on January 1 in history

The present-day location of Rio de Janeiro, Brazil is first explored by the Portuguese.

Rio de Janeiro (Portuguese pronunciation: [ˈχiw d(ʒi) ʒɐˈne(j)ɾu]), often referred to simply as Rio, meaning "River of January" in Portuguese, is Brazil’s second-most populous city and ranks sixth in population across the Americas. It serves as the capital of the state of Rio de Janeiro, Brazil’s third-most populous state, following São Paulo and Minas Gerais.
On July 1, 2012, UNESCO designated portions of Rio as a World Heritage Site under the title “Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea.” This recognition highlights the city’s unique integration of natural beauty and urban development, showcasing iconic sites like the Sugarloaf Mountain, Corcovado, and the hills, lagoons, and beaches that form its dramatic landscape.
Founded by the Portuguese in 1565, Rio de Janeiro originally served as the seat of the Captaincy of Rio de Janeiro, a colonial administrative division of the Portuguese Empire. Its strategic coastal location made it an important military and trade hub. In 1763, it became the capital of the State of Brazil, an integral state within the Portuguese Empire. A significant historical turning point occurred in 1808 when the Portuguese royal family, fleeing from Napoleon’s invasion of Portugal, relocated their court to Rio. This made the city the de facto capital of the Portuguese Empire — a rare occasion in world history where a colonial city assumed the governance of its metropole.
Under Prince Regent João VI (later King João VI of Portugal), the city gained prominence when Brazil was elevated to the status of a kingdom, forming the United Kingdom of Portugal, Brazil, and the Algarves. Rio remained the capital of the empire until Brazil declared independence in 1822. Subsequently, the city continued as the capital of the Empire of Brazil and, later, the Republic of Brazil until 1960, when the capital was officially moved to the newly established city of Brasília.
From an economic perspective, Rio has remained a powerful financial center. As of 2008, the city held the second-largest municipal GDP in Brazil and ranked 30th globally, with an estimated GDP of R$343 billion (around US$201 billion). It is home to major corporations, including the state oil giant Petrobras and the mining company Vale. The city also houses the headquarters of Grupo Globo, Latin America’s largest media conglomerate. Rio stands out as a vital research and educational hub, containing numerous esteemed universities and research institutions. In 2005, it accounted for 17% of Brazil’s national scientific output, affirming its role as the country’s second-largest center for research and development.
Despite frequent media portrayals highlighting crime, data reveals that Rio de Janeiro has a lower crime rate than many other Brazilian state capitals. Efforts to improve public safety have led to initiatives such as the Pacifying Police Units (UPPs), particularly in favelas.
Culturally, Rio de Janeiro is one of the Southern Hemisphere’s most visited cities and enjoys a global reputation for its vibrant traditions, festive spirit, and breathtaking natural surroundings. Tourists flock throughout the year, particularly during Carnival, an internationally celebrated event featuring samba music, parades, and dazzling costumes. The city is also famous for its iconic balneário beaches, such as Copacabana, Ipanema, Barra da Tijuca, and Leblon, which serve as social and recreational hubs.
Rio boasts landmarks that are recognized around the world:
- Christ the Redeemer (Cristo Redentor) atop Corcovado mountain — named one of the New Seven Wonders of the World
- Sugarloaf Mountain (Pão de Açúcar) — known for its scenic cable car rides and panoramic views
- The Sambódromo — a purpose-built parade venue designed by architect Oscar Niemeyer, central to Carnival celebrations
- Maracanã Stadium — once the largest football stadium in the world, it has hosted multiple historic events
The city has also gained global attention as a major host of international sporting events. In 2016, Rio made history by becoming the first South American and Portuguese-speaking city to host the Olympic and Paralympic Games. Major matches from multiple international tournaments — including the 1950 and 2014 FIFA World Cup Finals, the 2013 FIFA Confederations Cup, and the 2007 Pan American Games — were held at Maracanã Stadium.
