Rio de Janeiro
On the 1st of March 1565, Portuguese forces led by Estácio de Sá established the city of São Sebastião do Rio de Janeiro. This founding followed a years-long military campaign to expel French colonists who had occupied Villegagnon Island in Guanabara Bay since 1555. The French admiral Nicolas Durand de Villegaignon had built Fort Coligny there as part of an attempt to create France Antarctique. By the 20th of January 1567, the final defeat was imposed on these French forces, and they were decisively expelled from Brazil for good. The new settlement was named after St. Sebastian, the patron saint of the Portuguese monarch at the time. For decades following its establishment, the city faced repeated threats from French pirates and buccaneers like Jean-François Duclerc and René Duguay-Trouin. In the late 17th century, gold and diamond discoveries in Minas Gerais transformed Rio into a practical port for exporting wealth beyond sugar. On the 27th of January 1763, the colonial administration moved from Salvador to Rio de Janeiro, making it the capital of the State of Brazil.
In 1808, the entire Portuguese royal family fled Napoleon's invasion of Portugal and relocated to Rio de Janeiro. Queen Maria I of Portugal became the nominal ruler while her son, Prince Regent John of Braganza, effectively governed from the Brazilian city. This move made Rio the only European capital located outside Europe during that period. Hundreds of noblemen arrived suddenly, forcing many existing inhabitants out of their homes due to lack of space. Within the first decade, several educational institutions emerged including the Military Academy, the Royal School of Sciences, Arts and Crafts, and the Imperial Academy of Fine Arts. The National Library of Brazil was also established with what would become Latin America's largest collection. A printed newspaper began circulation during this era, marking early media development. When Brazil was elevated to Kingdom status in 1815, Rio remained the capital until the royal family returned to Lisbon in 1821. After independence in 1822, the city continued as the capital of both the Empire and later the Republic until 1960. Between 1811 and 1831, between 500,000 and one million enslaved Africans arrived through Valongo Wharf, which is now a World Heritage Site.
Pereira Passos took office as mayor in 1902 and immediately imposed sweeping reforms to modernize the crumbling colonial infrastructure. He demolished cortiços where most poor residents lived, displacing thousands who then moved to the hills creating the first favelas. Inspired by Parisian design, Passos constructed the Municipal Theater, the National Museum of Fine Arts, and expanded electric power systems across the city. Larger avenues were built to accommodate automobiles while Oswaldo Cruz served as Director General of Public Health. Cruz implemented compulsory vaccination campaigns and authorized forced entry into homes to eliminate mosquitoes and rats carrying disease. These aggressive public health measures sparked the Vaccine Revolt when citizens rebelled against state-enforced medical policies. In 1910, Afro-Brazilian navy crew members mutinied aboard the battleship Minas Geraes during the Revolt of the Lash, protesting heavy corporal punishment similar to slavery-era treatment. Another military uprising occurred in 1922 at Copacabana Fort, challenging Old Republic politics and marking the beginning of Tenentism. The city's center of gravity shifted southward toward what became known as Zona Sul during the early twentieth century. A tunnel was constructed under mountains connecting Botafogo with Copacabana, facilitating urban expansion. Streetcar transit systems were consolidated and electrified after 1905, enabling growth toward both north and south directions.
Rio de Janeiro holds the second-largest municipal GDP in Brazil, estimated at R$343 billion as of 2008. It ranks thirtieth globally among cities by economic output according to available data from that period. Major corporations maintain headquarters here including Petrobras, Vale, and Grupo Globo, Latin America's largest telemedia conglomerate. The city accounts for 17 percent of national scientific output based on 2005 research figures. Oil exploration began in the Campos Basin starting in 1968, establishing Rio as a primary site for petroleum production. Over four-fifths of all petroleum and fuels distributed nationwide originate from facilities located within the metropolitan area. More than 700 petrochemical companies operate locally including Shell, Esso, Ipiranga, Chevron, PRIO, and Repsol. Shipbuilding industries produce approximately 90 percent of ships and offshore equipment used throughout Brazil. Pharmaceutical giants such as Merck, Roche, Arrow, Darrow, Baxter, Mayne, and Mappel maintain Brazilian operations here. Media organizations like Organizações Globo generate around 10,000 direct jobs plus 30,000 indirect positions through television production complexes. In 2006 alone, studios in Rio created about 65 percent of all Brazilian cinema output generating 91 million reais via federal tax incentives.
Significant socioeconomic disparities exist between wealthy neighborhoods and slums known locally as favelas where 95 percent of residents live below poverty lines compared to 40 percent nationally. More than 1.3 million people reside across 813 distinct favelas representing 21 percent of Rio's total population. State-sanctioned violence statistics reveal that approximately 20 percent of all killings committed by security forces occur within the state. Police killed an average of five individuals daily throughout 2019 totaling 1,810 deaths that year, the highest recorded number since official tracking began in 1998. Government initiatives have attempted addressing these issues through programs like Cidade de Deus housing projects and Favela Bairro infrastructure improvements. Pacifying Police Units were deployed to bring conditions closer to those found elsewhere in the city though challenges persist. About half of the city's population identifies as mixed race or black according to recent census data showing complex phenotypic diversity rather than strict racial categories. Nearly 72 percent of foreign-born residents identified as Portuguese while their descendants accounted for over 51 percent of inhabitants historically. The black community formed largely from ancestors trafficked into slavery primarily originating from Angola and Mozambique
