Brazil occupies 8,515,767 square kilometers, making it the fifth-largest country on Earth by land area and the largest in South America. The country shares borders with every South American nation except Chile and Ecuador. This continental scale means that travel within Brazil often involves distances comparable to crossing multiple European countries. São Paulo sits 3,490 kilometers from Manaus by road, roughly the distance from London to Damascus. The territory extends from 5 degrees north of the equator to 33 degrees south latitude, spanning multiple climate zones from equatorial to subtropical.
The Amazon Rainforest covers approximately 5.5 million square kilometers across nine countries, with Brazil containing roughly 60 percent of this total, an area of about 3.3 million square kilometers. This Brazilian portion of the Amazon represents the largest tract of tropical rainforest under a single national jurisdiction. The Amazon River discharges approximately 209,000 cubic meters of water per second into the Atlantic Ocean, roughly 20 percent of all freshwater entering the world's oceans from rivers. The river stretches 6,400 kilometers from source to mouth, with approximately 3,000 kilometers navigable by large vessels. The Negro River, a major Amazon tributary, runs black due to tannins from decomposed organic matter and meets the brown Solimões River at the Meeting of Waters near Manaus, where the two flows run side by side for six kilometers without mixing due to differences in temperature, speed, and density.
The Pantanal covers approximately 150,000 square kilometers across Brazil, Bolivia, and Paraguay, with roughly 80 percent of the wetland lying within Brazilian territory in the states of Mato Grosso and Mato Grosso do Sul. This represents the world's largest tropical wetland area. The region floods seasonally between November and March, with water levels rising two to five meters across the floodplain. During dry season from April to September, water recedes into permanent channels and lagoons. Wildlife concentrations in the Pantanal during dry season reach densities rare in other ecosystems. The region contains an estimated 10 million caimans, the highest concentration of crocodilians anywhere on Earth. Jaguar density in certain Pantanal areas reaches 6.6 to 6.7 individuals per 100 square kilometers, compared to 2 to 8 individuals per 100 square kilometers in most Amazonian habitats.
Iguazu Falls sits on the border between Brazil's Paraná state and Argentina's Misiones province, created by the Iguazu River dropping 82 meters over a basalt precipice. The falls system comprises 275 individual drops spread across 2.7 kilometers. The Brazilian side of Iguaçu National Park covers 185,262 hectares, established in 1939. The most voluminous single drop, the Garganta del Diablo (Devil's Throat), lies on the Argentine side but remains visible from Brazilian viewpoints. Peak flow occurs between November and March, when the Iguazu River can discharge up to 12,800 cubic meters per second over the falls, compared to average flows of 1,746 cubic meters per second.
Fernando de Noronha archipelago sits 354 kilometers off the Brazilian coast in the Atlantic Ocean, comprising 21 islands and islets with a total land area of 26 square kilometers. The main island measures 17 square kilometers. Pernambuco state administers the territory, which became a national marine park in 1988 covering 112.7 square kilometers of land and sea. Daily visitor numbers to the archipelago are capped at 246 tourists plus 200 day-trippers from cruise ships, a limit established in 2012 to manage environmental impact. The marine park contains the highest concentration of resident dolphins in the Western Atlantic, with approximately 1,200 spinner dolphins in the surrounding waters. Visibility in the waters around Fernando de Noronha regularly exceeds 50 meters.
The Atlantic Forest originally covered approximately 1.3 million square kilometers along Brazil's eastern coast, extending from Rio Grande do Norte state in the north to Rio Grande do Sul in the south, and reaching inland to Paraguay and Argentina. Current estimates place remaining Atlantic Forest coverage at 12 to 16 percent of the original extent, fragmented into patches of varying sizes. Despite this reduction, the Atlantic Forest contains approximately 20,000 plant species, 40 percent of which exist nowhere else. The forest harbors 298 mammal species, 1,023 bird species, and 475 amphibian species. More tree species can be found in a single hectare of Atlantic Forest than exist in all of Europe. The Tijuca National Park in Rio de Janeiro, covering 3,953 hectares, represents the world's largest urban forest and constitutes regenerated Atlantic Forest, much of it replanted between 1861 and 1874 under the direction of Major Manuel Gomes Archer to restore the watershed that supplied Rio de Janeiro's water.
Lençóis Maranhenses National Park covers 155,000 hectares on the coast of Maranhão state in northeastern Brazil. The landscape consists of white sand dunes reaching up to 40 meters in height interspersed with seasonal freshwater lagoons. These lagoons form during the rainy season from January to June when the region receives approximately 1,600 millimeters of annual rainfall, roughly 300 times the precipitation that falls in the Sahara. The water collects in the troughs between dunes because an impermeable rock layer lies beneath the sand. The lagoons reach their fullest extent between July and September, after the rains end but before evaporation depletes them. Despite appearance, Lençóis Maranhenses is not a desert because it receives too much rainfall. Fish appear in the lagoons each year, surviving the dry season as eggs in the sand or swimming in from the Preguiças River that borders the park.
Brazil contains six major biomes: the Amazon, Atlantic Forest, Caatinga, Cerrado, Pantanal, and Pampa. The Cerrado savanna covers approximately 2 million square kilometers in central Brazil, making it the largest savanna region in South America and representing roughly 21 percent of Brazil's land area. The Cerrado contains approximately 12,000 plant species, 4,400 of which are endemic. The biome stores carbon in deep root systems extending up to 20 meters underground, with some estimates suggesting the Cerrado holds one-third of Brazil's terrestrial carbon despite occupying a smaller area than the Amazon. The Caatinga semi-arid region covers 734,478 square kilometers in northeastern Brazil, characterized by thorny shrubs and seasonal drought-deciduous vegetation. The Caatinga receives between 200 and 800 millimeters of rain annually, concentrated in a rainy season lasting three to five months.
The São Francisco River runs 2,914 kilometers from its source in Minas Gerais state to its mouth at the Atlantic Ocean on the border between Alagoas and Sergipe states. The river drains a basin of 641,000 square kilometers and remains the longest river entirely within Brazilian territory. Historical records refer to it as the "river of national unity" because it connected Brazil's interior to the coast during the colonial period. The Sobradinho Dam on the São Francisco, completed in 1979, created a reservoir covering 4,214 square kilometers, one of the largest artificial lakes in the world. Three additional major dams on the São Francisco—Três Marias, Paulo Afonso, and Xingó—generate hydroelectric power.
Mount Roraima rises 2,810 meters above sea level on the border between Brazil, Venezuela, and Guyana, the highest of the Pakaraima chain of tepuis (table-top mountains). The summit plateau covers approximately 31 square kilometers. Brazilian access to Roraima requires crossing into Venezuela, as no maintained trail reaches the summit from Brazilian territory. The tepui consists of Precambrian sandstone approximately two billion years old. Rainfall on the summit averages 4,000 millimeters annually, and the plateau remains shrouded in cloud approximately 85 percent of the time. The isolated summit ecosystem contains numerous endemic species that evolved separately from lowland populations for millions of years.
Brasília became Brazil's capital on April 21, 1960, when the federal government officially transferred from Rio de Janeiro. President Juscelino Kubitsch ordered the construction of the new capital in Brazil's interior as part of his "fifty years of progress in five" development plan. Architect Oscar Niemeyer designed the principal government buildings, while urban planner Lúcio Costa created the city layout in the shape of an airplane or bird, with residential zones along the wings and government buildings along the fuselage. The city was built in 41 months. UNESCO designated Brasília a World Heritage Site in 1987, the only city built in the 20th century to receive this designation. The city sits at 1,172 meters elevation on the Central Plateau, 1,207 kilometers from São Paulo and 1,148 kilometers from Rio de Janeiro. The planned city (Plano Piloto) was designed for 500,000 residents but the greater Federal District now contains approximately 3.1 million people, most living in satellite cities outside the original plan.
São Paulo's metropolitan region contains approximately 22 million people, making it the largest city in the Southern Hemisphere and the Portuguese-speaking world. The city proper holds approximately 12.3 million residents within 1,521 square kilometers. São Paulo produces roughly 10.7 percent of Brazil's GDP despite containing approximately 6 percent of the population. The municipality contains an estimated 40,000 to 50,000 restaurants and 15,000 bars. Avenida Paulista, the city's principal financial corridor, was cut through a ridgeline in 1891 and originally served as an address for coffee baron mansions; it now contains the headquarters of the majority of Brazil's largest banks. The city receives approximately 15 million tourists annually, most for business rather than leisure. São Paulo's subway system, opened in 1974, now extends for 104 kilometers with 89 stations, transporting approximately 4.7 million passengers daily.
Rio de Janeiro served as Brazil's capital from 1763 until 1960, first as the seat of the Portuguese colonial government, then the United Kingdom of Portugal, Brazil and the Algarves from 1815 to 1821, the Empire of Brazil from 1822 to 1889, and the Republic of Brazil from 1889 to 1960. The city's population stands at approximately 6.7 million in the municipality and 13.5 million in the metropolitan area. Sugarloaf Mountain (Pão de Açúcar) rises 396 meters above the harbor entrance; cable cars have transported visitors to the summit since 1912, with the current third-generation system installed in 1972. Christ the Redeemer statue (Cristo Redentor) atop Corcovado mountain stands 30 meters tall on an 8-meter pedestal, completed in 1931 with a design by Brazilian engineer Heitor da Silva Costa and French sculptor Paul Landowski. The statue's arm span reaches 28 meters. Approximately 6.5 million people visit the statue annually. Copacabana Beach extends 4 kilometers along the Atlantic coast, with the distinctive black-and-white wave-pattern mosaic sidewalk designed by Roberto Burle Marx laid in 1970. The New Year's Eve celebration on Copacabana regularly draws 2 to 3 million people.
Salvador served as Brazil's first capital from 1549 until 1763. The city's Pelourinho neighborhood contains the largest collection of colonial architecture in Latin America, with approximately 800 buildings from the 17th through 19th centuries. Salvador's population of approximately 2.9 million makes it Brazil's fourth-largest city. The city's location in Bahia state places it at the historical center of the African slave trade to Brazil; approximately 40 to 45 percent of all enslaved Africans brought to Brazil arrived through Salvador. This history created the strongest African cultural influence of any major Brazilian city, visible in cuisine, religion, music, and dance. The Festa do Senhor do Bonfim, held annually in January, draws hundreds of thousands of participants who wash the steps of the Igreja do Nosso Senhor do Bonfim church. Candomblé, an Afro-Brazilian religion combining Yoruba, Fon, and Bantu practices with Catholic elements, maintains an estimated 2,230 terreiros (temples) in Salvador.
Manaus sits at the confluence of the Negro and Solimões rivers in the heart of the Amazon, 1,450 kilometers from the Atlantic Ocean as the river flows. The city's population reached approximately 2.2 million by 2020. The Teatro Amazonas opera house opened in 1896 during the rubber boom, constructed with materials imported from Europe including 66,000 decorated ceramic tiles from Alsace on the dome and Italian marble on the stairs and columns. The theater seats 701 people and still hosts regular performances. Manaus operates as a Free Trade Zone established in 1967, creating tax incentives that turned the city into a major manufacturing center despite its rainforest location. The Manaus Free Trade Zone employs approximately 500,000 people and generates $30 billion in annual revenue across industries including electronics, motorcycles, and mechanical goods.
Ouro Preto in Minas Gerais state developed during Brazil's 18th-century gold rush and served as the capital of Minas Gerais from 1720 until 1897. The town's name translates to "black gold," referring to gold covered in iron oxide found in the region. Between 1700 and 1820, Minas Gerais produced approximately 1,000 metric tons of gold, roughly 80 percent of global gold production during this period. Ouro Preto's colonial center contains 23 baroque churches built between 1711 and 1785. The Igreja de São Francisco de Assis, completed in 1794, features ceiling paintings and soapstone carvings by Aleijadinho (Antônio Francisco Lisboa), a mulatto sculptor and architect who created most of his work while suffering from a degenerative disease that deformed his hands. UNESCO designated Ouro Preto Brazil's first World Heritage Site in 1980. The city sits at 1,179 meters elevation in the Serra do Espinhaço mountains. Current population numbers approximately 74,000.
The Portuguese court fled Lisbon ahead of Napoleon's invasion in 1807, arriving in Rio de Janeiro in March 1808 with approximately 10,000 to 15,000 courtiers, officials, and servants. This transfer made Rio de Janeiro the only European capital located outside Europe. Prince Regent João (later King João VI) opened Brazilian ports to trade with friendly nations immediately upon arrival, ending the Portuguese colonial monopoly. The royal presence transformed Rio de Janeiro from a colonial outpost to an imperial capital. João VI returned to Portugal in 1821, leaving his son Pedro in Brazil. On September 7, 1822, Pedro declared Brazilian independence from Portugal at Ipiranga near São Paulo, proclaiming "Independence or Death" (Independência ou Morte). He became Emperor Pedro I of Brazil while remaining heir to the Portuguese throne, which he briefly claimed as Pedro IV of Portugal in 1826 before abdicating in favor of his daughter Maria II.
Pedro I abdicated the Brazilian throne in 1831 in favor of his five-year-old son, who became Emperor Pedro II in 1831 but did not assume active rule until 1840 at age 14. Pedro II reigned for 58 years until overthrown by a military coup in 1889. He is generally regarded as having provided stable governance, promoted education and infrastructure, and defended freedom of speech. Under his rule, Brazil fought the Paraguayan War (1864-1870) as part of the Triple Alliance with Argentina and Uruguay against Paraguay, the deadliest interstate conflict in South American history. Estimates place Paraguayan casualties at 60 to 70 percent of the pre-war population. Brazil abolished slavery on May 13, 1888, through the Lei Áurea (Golden Law) signed by Princess Isabel while Pedro II was abroad. Brazil was the last country in the Americas to abolish slavery. The military overthrew the monarchy on November 15, 1889, establishing a republic. Pedro II went into exile in Europe, where he died in 1891.
Brazil declared war on the Central Powers in October 1917, the only South American country to send troops to fight in World War I. The Brazilian Navy participated in Atlantic patrols, and a medical team served on the French front. In World War II, Brazil initially maintained neutrality but German U-boat attacks on Brazilian merchant ships in 1942 pushed the government to declare war on the Axis powers. Brazil sent the Brazilian Expeditionary Force (FEB), approximately 25,700 soldiers, to fight alongside the U.S. Fifth Army in the Italian Campaign from 1944 to 1945. The FEB fought at Monte Castello, Montese, and in the breakthrough of the Gothic Line. Brazil lost 466 soldiers killed in action in Italy. Brazilian participation in World War II ended the Estado Novo dictatorship of Getúlio Vargas, as the contradiction between fighting fascism abroad while maintaining authoritarian rule at home became politically untenable.
