from Wikipedia

The Southeast Region of Brazil (Portuguese: Região Sudeste do Brasil [ʁeʒiˈɐ̃w suˈdɛstʃi du bɾaˈziw]) is composed of the states of Espírito Santo, Minas Gerais, Rio de Janeiro and São Paulo. It is the richest region of the country, responsible for approximately 53% of the Brazilian GDP (2022)[2] , as São Paulo, Rio de Janeiro, and Minas Gerais are the three richest states of Brazil, the top three Brazilian states in terms of GDP. The Southeast of Brazil also has the highest GDP per capita among all Brazilian regions.

Key Information

The Southeast region accounts for about 44% of Brazil's total population, leading the country in population, urban population, population density, vehicles, industries, universities, airports, ports, highways, hospitals, schools, houses and many other areas.

Geography

Heart of the largest continued remnant of the Brazilian Atlantic Forest, the Ribeira Valley is a Natural Heritage of Humanity, granted heritage as a Biosphere Reserve by UNESCO. One of the biggest attractions is the biologic and ecosystems diversity, where approximately 400 species of birds, amphibians, reptiles and mammals live. The Alto Ribeira Tourist State Park (PETAR) is paradise for ecotourists, for its enormous diversity in geologic formations, among grottos and caves, rivers and waterfalls. There are currently 454 caves registered by the Brazilian Society of Speleology (SBE) in the State of São Paulo, all at the Ribeira Valley. The 280 caves located at PETAR represent the biggest concentration of caves in Brazil.

Minas Gerais

The landscape of the State is marked by mountains, valleys and caverns. In the Serra do Cipó, Sete Lagoas, Cordisburgo and Lagoa Santa, the caves and waterfalls. Minas Gerais is the source of some of the biggest rivers in Brazil, most notably the São Francisco, the Paraná and to a lesser extent, the Rio Doce. The state also holds many hydroelectric power plants, including Furnas dam. Some of the highest peaks in Brazil are in the mountain ranges in the southern part of the state, such as Serra da Mantiqueira and Serra do Cervo, which mark the border between Minas and its neighbors São Paulo and Rio de Janeiro. The most notable one is the Pico da Bandeira, the third highest mountain in Brazil at 2890 m, standing on the border with Espírito Santo state. The state also has huge reserves of iron and sizeable reserves of gold and gemstones, including emerald, topaz and aquamarine mines.

Rio de Janeiro

[edit]

The state is part of the Mata Atlântica biome, and its topography comprises both mountains and plains, located between the Mantiqueira Mountains and the Atlantic Ocean. Its coast is carved by the bays of Guanabara, Sepetiba and Ilha Grande. There are prominent slopes near the ocean, also featuring diverse environments, such as restinga vegetation, bays, lagoons and tropical forests. Rio de Janeiro is the smallest state in the Southeast macroregion and one of the smallest in Brazil. It has, however, the third longest coastline in the country (second only to Bahia's and Maranhão's), extending 635 kilometers.

Espírito Santo

[edit]

With a 46.180 square kilometers, it is about the size of Estonia, or half the size of Portugal, and has a variety of habitats including coastal plains, lakes, mountain forest, mangroves and many others. The main river in the state is the Doce. Other important river basins include the Santa Maria River Basin which is the northern branch of rivers which join the sea at Vitoria, and Jucu River Basin which flows into the sea at roughly the same place, but corresponds to the southern branch (which seems to come out of Vitoria). Espírito Santo's climate is tropical along the coast, with dry winters and rainy summers. North of Doce River it's generally drier and also hot. In the mountainous regions in the south and south west of the state, the tropical climate is strongly influenced by altitude, and the average temperatures are colder. The state can be divided into two areas: the low lying coastline and the highland area known as Serra (where one can find the 2.890 m Pico da Bandeira mountain), which is part of the larger Serra do Caparaó, the Caparaó Mountain Range. In the map to the right it is in the gray area in the extreme southwest of the state, and is shared with Minas Gerais.

  • soy (7% of the country's production, which is the largest producer in the world);
  • potato, carrot and strawberry (more than 50% of the country's production).[6]

Livestock

[edit]

The livestock also has great prominence in the region.

The Southeast is the second national producer of milk, with 34.2%, slightly losing compared to the South Region, which produces 35.7%. The southeast has the largest herd of cows milked: 30.4% of the total of 17.1 million existing in Brazil. The highest productivity, however, is that of the Southern Region, with an average of 3,284 liters per cow per year, which is why it has led the milk production ranking since 2015. Minas Gerais is the main milk-producing state in Brazil with the largest it is also effective for milked cows, responsible for 26.6% of production and 20.0% of all animals in milk. The municipality of Patos de Minas was the second largest producer in 2017, with 191.3 million liters of milk.

Poultry farming and egg production are the most important in the country. Flocks of poultry, according to IBGE, include chickens, roosters, hens and chicks. In 2018, the South region, with an emphasis on the creation of chickens for slaughter, was responsible for almost half of the Brazilian total (46.9%). Paraná only represented 26.2%. However, the situation is reversed when it comes to chickens. The first region in the ranking was the Southeast, with 38.9% of the country's total capital. A total of 246.9 million hens was estimated for 2018. The state of São Paulo was responsible for 21.9%. The national production of chicken eggs was 4.4 billion dozen in 2018. The Southeast region was responsible for 43.8% of the total produced. The state of São Paulo was the largest national producer (25.6%), with a total of 16.8 million birds. The Southeast is responsible for 64%, highlighting São Paulo (24.6%) and Espírito Santo (21.0%).

Mining

[edit]

In mineral production, in 2017, Minas Gerais was the country's largest producer of iron (277 million tons worth R $37.2 billion), gold (29.3 tons for a value of R $3.6 billion), zinc (400 thousand tons for a value of R $351 million) and niobium (in the form of hydrochloride) (131 thousand tons for a value of R $254 million). In addition, Minas was the second largest producer of aluminum (bauxite) (1.47 million tons at a value of R $105 million), third of manganese (296 thousand tons to a value of R $32 million) and 5th of tin (206 tons worth R $4.7 million). Minas Gerais had 47.19% of the value of the production of minerals marketed in Brazil (first place), with R $41.7 billion.[7][8][9][10] The state has the largest production of various gemstones in the country. In aquamarine, Minas Gerais produces the most valuable stones in the world. In diamond, Brazil was the world's largest producer of diamonds from 1730 to 1870, mining occurred for the first time in the Serra da Canastra, region of Diamantina, even lowering the price of stone in everyone due to excess production. Minas Gerais continues to extract diamonds, in addition to having larger or smaller scale productions of agate, emerald, garnet, jasper, amethyst, and sapphire. Topaz and tourmaline stand out. Imperial Topaz, a valued variety of topaz, is only found in Ouro Preto. Brazil is the world's leading producer of topaz. It is also one of the world's largest tourmaline producers.[11][12][13]

In the Southeast region, the industrialization of the country began, making the transformation industry the main source of income and work in its states. The state of São Paulo became the largest industrial park in South America.

The Southeast Region has 53% of the industrial GDP of Brazil.[14][15][16] [17]

The main industrial activities in the region are:

  • Iron and steel industry and metallurgy: It's in this region that the first industry of this type is located, the Companhia Siderúrgica Nacional, in the city of Volta Redonda, due to its proximity to a large area of iron mining, the so-called "iron quadrilateral", in the state of Minas Gerais. The Usiminas, in Ipatinga, which today is the largest crude steel producer in the country, and the Companhia Siderúrgica de Tubarão, in Vitória, Espírito Santo, are also installed in the region. The Southeast Region produces around 90% of the country's steel.

In Brazil, the automobile sector represents around 22% of industrial GDP. The Greater ABC Region, in São Paulo, is the first center and the largest automobile center in Brazil. When the country's manufacturing was practically restricted to ABC, the State represented 74.8% of Brazilian production in 1990. In 2017, this index decreased to 46.6%, and in 2019, to 40.1%, due to a phenomenon of internalization of the production of vehicles in Brazil, driven by factors such as unions, which made excessive labor and payroll charges, discouraged investment and favored the search for new cities. The development of the ABC cities helped curb appeal, due to rising real estate costs and higher density of residential areas. Sul Fluminense (Rio de Janeiro) was already the second largest pole in 2017, but in 2019 it fell to fourth place, behind Paraná (15%) and Minas Gerais (10.7%). In the Southeast there are factories of GM, Volkswagen, Fiat, Ford, Honda, Toyota, Mitsubishi, Nissan, Hyundai, Mercedes-Benz, Land Rover, Citroen / Peugeot, Scania and Iveco.[18][19]

In the production of tractors, in 2017, the main manufacturers in Brazil were John Deere, New Holland, Massey Ferguson, Valtra, Case IH and the Brazilian Agrale. They all have factories in the southeast, basically in São Paulo.[20]

  • Petroleum: Almost all of Brazil's oil and natural gas is extracted in the Southeast, mainly in Rio de Janeiro, but also in Espírito Santo and São Paulo. Most of the oil refining is also carried out in the region. Rio de Janeiro presents great importance in oil prospecting, which São Paulo has a great importance in the refining activity, being located in that state the main refineries of the country, among them, the REPLAN, the main of the country. In addition to oil, there is the extraction of natural gas from the Santos maritime basin and, until a few years ago, there was the extraction of bitumen in the Paraíba river valley.
  • High technology: The so-called "Brazilian silicon valley" is located in that region, made up of the cities of São Paulo, São José dos Campos, São Carlos and Campinas. These four cities concentrate industries of computing, telecommunications, electronics and other activities involving high technology; in addition to having important research centers and important universities, such as the "Technological Institute of Aeronautics" - ITA, in São José dos Campos. Brazil has two large production centers for electronic products, located in the Metropolitan Region of Campinas, in the State of São Paulo, and in the Manaus Free Trade Zone, in the State of Amazonas. There are large internationally renowned technology companies, as well as part of the industries that participate in their supply chain. The country also has other smaller centers, such as the municipalities of São José dos Campos and São Carlos, in the state of São Paulo. In Campinas there are industrial units of groups such as General Electric, Samsung, HP and Foxconn, a manufacturer of Apple and Dell. São José dos Campos, focuses on the aviation industry. This is where the headquarters of Embraer, a Brazilian company that is the third largest aircraft manufacturer in the world, after Boeing and Airbus, is located. In the production of cell phones and other electronic products, Samsung produces in Campinas; LG produces in Taubaté; Flextronics, which produces Motorola cell phones, produces in Jaguariúna; and Semp-TCL produces in Cajamar. In Santa Rita do Sapucaí, Minas Gerais, 8 thousand jobs are linked to the sector, with more than 120 companies. Most produce equipment for the telecommunications industry, such as decoders, including those used in the transmission of the digital television system.[21][22][23]

In 2011, Brazil had the sixth largest chemical industry in the world, with net sales of $157 billion, or 3.1% of world sales. At that time, there were 973 factories of chemical products for industrial use. They are concentrated in the Southeast Region, mainly in São Paulo. In 2018, the Brazilian chemical sector was the eighth largest in the world, representing 10% of the national industrial GDP and 2.5% of the total GDP. In 2020, imports will occupy 43% of domestic demand for chemical products. Since 2008, the average use of capacity in the Brazilian chemical industry has been at a level considered low, ranging between 70 and 83%.[24][25][26]

In pharmaceutical Industry, most of the companies in Brazil have been established in São Paulo and Rio de Janeiro for a long time. In 2019, the situation was that, due to the tax advantages offered in states such as Pernambuco, Goiás and Minas Gerais, companies were leaving RJ and SP and going to these states. In 2017, Brazil was considered the sixth largest pharmaceutical market in the world. Drug sales in pharmacies reached around R $57 billion (US$17.79 billion) in the country. The pharmaceutical market in Brazil had 241 regulated and authorized laboratories for the sale of medicines. Of these, the majority (60%) have national capital. Multinational companies had approximately 52.44% of the market, with 34.75% in commercialized packaging. Brazilian laboratories represent 47.56% of the market in sales and 65.25% in cases sold. In the distribution of drug sales by state, São Paulo ranked first: São Paulo's pharmaceutical industry had a turnover of R $53.3 billion, 76.8% of total sales throughout the country. The companies that benefited the most from the sale of drugs in the country in 2015 were EMS, Hypermarcas (NeoQuímica), Sanofi (Medley), Novartis, Aché, Eurofarma, Takeda, Bayer, Pfizer and GSK.[27][28][29]

In food industry, in 2019, Brazil was the second largest exporter of processed foods in the world, with a value of US$34.1 billion in exports. The revenue of the Brazilian food and beverage industry in 2019 was R $699.9 billion, 9.7% of the country's gross domestic product. In 2015, the food and beverage industrial sector in Brazil comprised 34,800 companies (not counting bakeries), the vast majority of which were small. These companies employed more than 1,600,000 workers, making the food and beverage industry the largest employer in manufacturing. There are around 570 large companies in Brazil, which account for a good part of the industry's total income. São Paulo created companies such as: Yoki [pt], Vigor, Minerva Foods, Bauducco, Santa Helena, Marilan, Ceratti, Fugini, Chocolates Pan, Embaré, among others. Minas Gerais created food companies of national importance such as Itambé and Pif Paf Alimentos. Espírito Santo created Chocolates Garoto and Rio de Janeiro created Piraquê and Granfino.[30][31][32]

In the Footwear industry, in 2019 Brazil produced 972 million pairs. Exports were around 10%, reaching almost 125 million pairs. Brazil ranks fourth among world producers, behind China, India and Vietnam, and 11th among the largest exporters. Of the pairs produced, 49% were made of plastic or rubber, 28.8% were made of synthetic laminate, and only 17.7% were made of leather. The largest pole in Brazil is in Rio Grande do Sul, but São Paulo has important shoe centers, such as the one in the city of Franca, specialized in men's footwear, in the city of Jaú, specialized in women's footwear and in the city of Birigui, specialized in footwear. children. Jaú, Franca and Birigui represent 92% of footwear production in the state of São Paulo. Birigui has 350 companies, which generate around 13 thousand jobs, producing 45.9 million pairs per year. 52% of children's shoes in the country are produced in this city. From Birigui came most of the most famous children's shoe factories in the country. Jaú has 150 factories that produce around 130 thousand pairs of cheap women's shoes per day. The footwear sector in Franca has around 550 companies and employs about 20,000 employees. Most of the most famous men's shoe factories in the country come from São Paulo. Minas Gerais has a pole specialized in cheap shoes and shoes in Nova Serrana. The city has around 830 industries, which in 2017 produced around 110 million pairs. However, overall, the Brazilian industry has been struggling to compete with Chinese footwear, which is priced unbeatable due to the difference in tax collection from one country to another, in addition to the absence of heavy Brazilian labor taxes in China, and the Brazilian businessman has had to invest in value-added products, combining quality and design, in order to survive.[33][34][35][36][37]

In textile industry, Brazil, despite being among the 5 largest producers in the world in 2013, and being representative in the consumption of textiles and clothing, has very little insertion in world trade. In 2015, Brazilian imports ranked 25th (US$5.5 billion). And in exports, it was only 40th in the world ranking. Brazil's participation in the world trade of textiles and clothing is only 0.3%, due to the difficulty of competing in price with producers in India and mainly in China. The gross value of production, which includes the consumption of intermediate goods and services, of the Brazilian textile industry corresponded to almost R $40 billion in 2015, 1.6% of the gross value of industrial production in Brazil. São Paulo (37.4%) is the largest producer. The main productive areas of São Paulo are the Metropolitan Region of São Paulo and Campinas. Minas Gerais has 8.51% (third largest production in the country).[38]

In home appliance industry, sales were 12.9 million units in 2017. The sector had its sales peak in 2012, with 18.9 million units. The brands that sold the most were Brastemp, Electrolux, Consul and Philips. Brastemp is originally from São Bernardo do Campo. São Paulo was also the place where Metalfrio was founded.[39]

International Airports

[edit]
São Paulo-Guarulhos International Airport (GRU).

São Paulo-Guarulhos International Airport connects Brazil to 28 countries with nearly 100,000 daily visitors. With capacity to serve 15 million passengers a year, in two terminals, the airport currently handles 12 million users. Construction of a third passenger terminal is pending, to raise yearly capacity to 29 million passengers. The project, in the tendering phase, is part of the airport's master plan and will get under way shortly. São Paulo International Airport is also one of the main air cargo hubs in Brazil. The roughly 100 flights a day carry everything from fruits grown in the São Francisco Valley to the most sophisticated medications created by science. The airport's cargo terminal is South America's largest and stands behind only Mexico City's in all of Latin America. In 2003, over 75,000 metric tons of freight passed through the terminal.

Since August 2004, with the transfer of many flights from Santos-Dumont Airport, Rio de Janeiro International Airport has returned to being the main doorway to Brazil. According to data from the official Brazilian travel bureau, Embratur, nearly 40% of foreign tourists who visit Brazil choose Rio as their gateway, meaning Galeão Airport. Besides linking Rio to the rest of Brazil with domestic flights, Galeão has connections to more than 18 countries. It can handle up to 15 million users a year in two passenger terminals. Located only 20 kilometers from downtown Rio, the international airport is served by several quick access routes, such as the Linha Vermelha and Linha Amarela freeways and Avenida Brasil, thus conveniently serving residents of the city's southern, northern and western zones. There are special shuttle buses linking Galeão to Santos-Dumont, and bus and taxi service to the rest of the city. The airport complex also has Brazil's longest runway at 4.240 meters, and one of South America's largest and best equipped cargo logistics terminals.

The Confins International Airport in the main hub in Minas Gerais.

Tancredo Neves/Confins International Airport is located in the municipalities of Lagoa Santa and Confins, 38 km from Belo Horizonte, and was opened in January 1984. It was planned from the start for future expansion in steps to meet growing demand. The first step was undertaken with careful concern for the environment, including monitoring by specialized consultants, since the region has a rich archeological heritage. The airport's location is attested to by the fact it has one of the lowest rates of shutdown for bad weather in the country. Confins is certified by the ISO 9001 standard, covering ten processes in the administrative, operational, safety/security and maintenance areas. Starting in March 2005, Confins Airport will receive flights that currently use Pampulha Airport.

National Airport

[edit]

Vitoria Airport is located on a land plot of just over 5.2 million square meters. Since construction of its first step, finished in 1946, Vitória Airport has undergone several expansions and modernizations, but current demand has surpassed its capacity of 560 thousand passengers a year. The recent construction of new aircraft parking boxes on the aprons has improved the airport's operational efficiency. In 2003 more than 1.2 million passengers used the airport, and in 2004 this rose to some 1.25 million. Vitória is one of the 32 airports in the Infraero network that has a cargo terminal. In May 1999 the first direct international freight connection to the United States (Miami) began operating to Vitória, facilitating imports to the state of Espírito Santo. Today there are five of such flights a week.

Highways

[edit]

The Southeast Brazilian region is highly covered by Paved roads – due to the policy in the Brazil's economy in the 1960s (automobilization of the country) – which led to the car's manufacturing to be a major industry not only in the region but in Brazil as well.

The Southeast's highways are generally in good or very good conditions – some exceptions are made to the southern parts of the BR-101.

Railways are present as well (and also, the region is more covered than any other region), but mainly for freight transport – soy beans and iron ore, mainly, from the farms and mines to the seaports.

Also, a very complicated hydrocanal system is present in the region, with ten major dams.

The Pampulha Church in Belo Horizonte is one of the most expressive symbols of the Brazilian Modern Architecture.
São Paulo is the largest Brazilian city.

Health care and education are of major concern in the larger cities, but in smaller ones, the population are generally well-looked after.

Geography

Location and Borders

The Southeast Region of Brazil occupies the southeastern part of the country, situated between approximately 15°S and 25°S and 35°W and 55°W . This positioning places it in a transitional zone between tropical and subtropical climates, influencing its diverse economic activities. The region is defined by the Instituto Brasileiro de Geografia e Estatística (IBGE) as one of Brazil's five major geographic divisions, emphasizing its role as a key connector between the nation's interior and coastal zones. To the north, the region shares borders with the Central-West Region (via the states of Goiás and Mato Grosso do Sul) and the Northeast Region (primarily with Bahia). In the south, it adjoins the South Region along the boundary with Paraná. The eastern edge is defined by over 1,000 kilometers of coastline along the Atlantic Ocean, encompassing the shores of Rio de Janeiro, Espírito Santo, and São Paulo states, which support major ports and tourism hubs. To the west, it maintains a brief international border with Paraguay, limited to a segment within São Paulo state near the Paraná River, totaling part of the 1,290 kilometers of the overall Brazil-Paraguay boundary. These borders, both domestic and international, facilitate extensive trade and migration flows. Covering a total area of 924,511 km², the Southeast Region accounts for about 10.9% of Brazil's national territory, positioning it as the second-smallest among the five regions after the . This compact size belies its outsized economic importance, with the land encompassing varied terrains from coastal plains to inland plateaus. The region includes four states— (area 248,222.4 km²), (586,552.1 km²), Rio de Janeiro (43,696.5 km²), and (46,077.5 km²)—whose capitals, , , Rio de Janeiro, and Vitória, respectively, function as primary gateways for regional and international access via airports, seaports, and highways.

Physical Features

The Southeast Region of Brazil exhibits a diverse topography characterized by ancient plateaus, rugged mountain ranges, and elevated terrains that define its landscape. The region is dominated by the Brazilian Plateau, with significant highland areas including the Planalto de Minas and the Planalto Atlântico. Key mountain systems include the Serra do Mar, a coastal range extending parallel to the Atlantic Ocean and averaging elevations between 800 and 900 meters, and the Serra da Mantiqueira, an inland range spanning São Paulo, Minas Gerais, and Rio de Janeiro states, known for its steep escarpments and peaks exceeding 2,000 meters. These ranges form natural barriers influencing local drainage and climate patterns. Notable waterfalls include Iguaçu Falls on the border with Paraná state. The highest point in the region, and the third highest in Brazil, is Pico da Bandeira at 2,890 meters, located on the border between Minas Gerais and Espírito Santo within the Caparaó National Park. This peak exemplifies the region's tectonic uplift and erosion history, contributing to its scenic highlands. The hydrology of the Southeast Region is marked by several major river systems that originate or traverse its territories, supporting extensive drainage networks. The , one of Brazil's longest entirely domestic rivers at 2,914 kilometers, originates in the highlands of near the town of Diamantina and flows northeastward, forming part of the region's interior watershed before heading to the Northeast. In , tributaries such as the Tietê and Paranapanema contribute to the system, which drains southward into the larger Basin and plays a critical role in hydroelectric generation and agriculture. Coastal rivers in Rio de Janeiro, including the Paraiba do Sul and , are shorter but vital for local ecosystems, flowing directly into the Atlantic and shaping narrow alluvial plains along the shore. These rivers reflect the region's varied relief, with headwaters in elevated plateaus feeding into broader basins. The region's coastline stretches over 1,000 kilometers along the Atlantic Ocean, encompassing the shores of , Rio de Janeiro, and states, and features a mix of sandy beaches, rocky cliffs, and indented bays that enhance its biodiversity. Prominent coastal formations include in Rio de Janeiro, a large estuarine bay covering 412 square kilometers with a perimeter of 143 kilometers, formed by tectonic and fluvial , serving as a natural harbor for the city of Rio de Janeiro. Further south, , a 193-square-kilometer island off the coast of Rio de Janeiro, exemplifies the region's archipelagic features with its granite outcrops, forested hills rising to 1,031 meters at Pico da Pedra d'Água, and surrounding reefs, protected as part of a for its ecological integrity. These coastal elements arise from the interplay of , wave action, and underlying geology. Geologically, the Southeast Region is underlain by ancient formations that form the core of the Brazilian Shield, with variations across states reflecting prolonged tectonic evolution. In , vast shields dominate, comprising and cratons with gneissic and granitic complexes dating back over 2 billion years, as seen in the Quadrilátero Ferrífero where iron-rich metasediments and greenstone belts record early continental assembly. São Paulo state features sedimentary basins such as the São Paulo and Taubaté basins, intracratonic structures filled with deposits up to age, including alluvial and lacustrine sediments that overlay the basement and influence groundwater aquifers. In , geological diversity includes volcanic influences from alkaline intrusions and volcaniclastic rocks associated with the opening of the South Atlantic, evident in basaltic flows and tuffaceous layers within the offshore Santos Basin extension, alongside terrains deformed during the Brasiliano orogeny around 600 million years ago. These features underscore the region's stable cratonic interior punctuated by rifting and magmatism.

Climate and Environment

The Southeast Region of Brazil exhibits a diverse influenced by its coastal and highland . Coastal areas, including parts of Rio de Janeiro and , predominantly feature tropical climates classified as Aw (tropical ) or Am (tropical ) under the Köppen system, characterized by high humidity and distinct wet and dry seasons. In contrast, the higher elevations of the Serra da Mantiqueira and other inland highlands, such as those in and , transition to humid subtropical climates (Cfa), with milder winters and more even rainfall distribution. Average annual temperatures across the region range from 20°C to 25°C, with coastal zones often warmer due to oceanic influences. Annual precipitation typically falls between 1,000 mm and 2,000 mm, concentrated in the summer months from to March, though mountainous terrain can create localized microclimates with higher rainfall exceeding 2,500 mm in some areas. Urbanization exacerbates climatic conditions in densely populated areas, notably through the effect in , where nighttime temperatures can rise by 6–8°C compared to surrounding rural areas due to heat retention by and asphalt surfaces. This phenomenon intensifies heat stress during summer, contributing to higher demands for cooling and potential risks for residents. The region's vegetation is dominated by the Atlantic Forest (Mata Atlântica), a once-expansive that originally covered approximately 1.5 million km² along the eastern seaboard, now reduced to less than 12% of its extent due to historical deforestation for agriculture and urbanization. Remnants persist in fragmented patches, particularly in and Rio de Janeiro, supporting dense rainforests with epiphytes, tall hardwoods, and diverse understories. In western , the landscape shifts to the , a tropical featuring fire-adapted grasses, shrubs, and scattered trees with thick bark, covering transitional zones between the Atlantic Forest and interior plateaus. Coastal estuaries host ecosystems, with species like forming dense fringes that stabilize shorelines and provide habitat for marine life along the shores of and Rio de Janeiro. Ecologically, the Southeast Region encompasses global biodiversity hotspots, particularly the Atlantic Forest and portions of the , harboring over 20,000 plant species—nearly half endemic—and a rich array of vertebrates, including endangered and birds. However, these ecosystems face ongoing threats from habitat loss, with the Atlantic Forest remnants experiencing an annual rate of approximately 0.2% in 2022 (30,091 hectares), primarily for urban expansion and soy cultivation. decreased to 29,916 hectares (about 0.17%) in 2023. This degradation undermines ecosystem services like water regulation and , though the mangroves and areas maintain resilience through adaptive vegetation structures.

History

Colonial Era

The Portuguese exploration of the Brazilian coast began with Pedro Álvares Cabral's fleet landing at Porto Seguro on April 22, 1500, marking the official discovery of the territory for Portugal and influencing subsequent settlements in the adjacent regions, including the Southeast. Although initial contacts were brief and focused on trade with indigenous groups, permanent colonization efforts intensified in the early 16th century. The first enduring European settlement in the Southeast was established at São Vicente in 1532 by Martim Afonso de Sousa, who founded the town as part of the captaincy system to secure Portuguese claims against French and other rivals; this site served as a base for further expansion into the interior of present-day São Paulo state. Economic activities in the colonial Southeast were driven by resource extraction and agriculture, with sugar plantations emerging along the coasts of Rio de Janeiro and Espírito Santo from the mid-16th century onward, relying on enslaved labor to produce for export to Europe. These mills, though smaller in scale than those in the Northeast, contributed to the region's integration into the Atlantic economy and laid the groundwork for plantation-based social structures. The discovery of gold in the 1690s in Minas Gerais triggered a massive influx of settlers and slaves, transforming the interior; between 1700 and 1800, Brazilian mines, primarily in this region, accounted for approximately 80 percent of global gold production, peaking in the 1750s and fueling Portugal's economy while causing rapid urbanization in areas like Ouro Preto. Administrative control was solidified through the establishment of captaincies, such as the Royal Captaincy of Rio de Janeiro in 1565, founded by Mem de Sá to defend against French incursions and oversee the growing sugar and later mining interests; Rio became a key port for exporting these commodities. Tensions culminated in the Inconfidência Mineira, a 1789 conspiracy among local elites, intellectuals, and military figures in Minas Gerais against Portuguese taxation and administrative overreach, inspired partly by Enlightenment ideas and the American Revolution, though it was swiftly suppressed with executions, including that of leader Joaquim José da Silva Xavier (Tiradentes). The social fabric of the colonial Southeast was shaped by the enslavement of indigenous populations, such as the along the São Paulo and Rio coasts, who were captured for labor in early settlements and plantations despite papal prohibitions, leading to demographic collapse through disease and exploitation. As indigenous supplies dwindled, African slavery became dominant, with the Southeast receiving a significant portion of the enslaved Africans imported to during the colonial era, particularly through the port of Rio de Janeiro which handled about 2 million arrivals—roughly 40 percent of the national total—especially for in where slaves comprised up to 80 percent of the workforce by the mid-18th century. This system entrenched racial hierarchies that persisted beyond the colonial period.

Independence to Republic

The arrival of the Portuguese royal court in Rio de Janeiro on March 7, 1808, marked a pivotal shift for the Southeast Region, elevating Rio from a colonial outpost to the de facto capital of the Portuguese Empire amid Napoleonic threats in Europe. This transfer, involving over 15,000 people including King Dom João VI, transformed the city's infrastructure and economy, fostering early administrative and cultural developments that laid the groundwork for regional autonomy. By 1822, tensions with culminated in Brazil's , with Rio de Janeiro serving as the provisional capital under Emperor I, who was crowned later that year. 's proclamation on September 7, 1822, along the Ipiranga River near , symbolized the break from colonial rule, while played a key role in supporting constitutionalist movements that advocated for a liberal and limited royal powers in the . During the Empire era from 1822 to 1889, the Southeast Region drove Brazil's economic expansion through a coffee boom centered in São Paulo and western Minas Gerais, where fertile soils and expanding plantations made the area the nation's leading coffee producer. This surge, fueled by international demand and slave labor, positioned the region as Brazil's agricultural powerhouse, with exports from ports like Rio de Janeiro and Santos underpinning imperial finances. The 1888 abolition of slavery, enacted via the Golden Law in Rio de Janeiro, profoundly disrupted Espírito Santo's plantation economy, which relied heavily on enslaved workers for coffee and sugar cultivation, leading to labor shortages and a gradual shift toward immigrant wage systems. The proclamation of the on November 15, 1889, occurred in Rio de Janeiro through a military coup led by Marshal , deposing Emperor Pedro II and ending the monarchy without widespread violence. This transition reorganized Brazil's provinces into federal states, granting the Southeast's entities—Rio de Janeiro (as the ), São Paulo, , and —greater autonomy under the 1891 Constitution. emerged as a political powerhouse in the early , dominating national leadership through the "coffee with milk" alliance with São Paulo and producing presidents like , who served from 1906 to 1909 and advanced federal infrastructure projects. Key events underscored regional tensions during this period, including spillover effects from the Canudos War (1896–1897) along the Bahia-Minas Gerais border, where military campaigns against the settlement displaced communities and strained border resources amid broader republican consolidation efforts. The 1930 Revolution, which ended the First Republic, originated in part from , where dissident elites and military leaders challenged federal elections, allying with forces in and to install in power by October 24.

Modern Developments

The Southeast Region of Brazil underwent significant industrialization from the 1930s to the 1980s, driven by policies under President that emphasized (ISI) to foster domestic manufacturing. These measures, including protective tariffs and state-led investments, particularly boosted 's , metallurgical, and automotive sectors, transforming the state into Brazil's industrial powerhouse and contributing to urban growth through migration from rural areas. This era laid the foundation for the region's economic dominance, with manufacturing output in alone accounting for a substantial share of national production by the . During the from 1964 to 1985, the Southeast remained a center of economic activity but also emerged as a hub for cultural resistance, especially in Rio de Janeiro, where artists and intellectuals used theater, music, and to subtly critique the regime's censorship and repression. Figures like developed innovative performance techniques in Rio to evade authoritarian controls, fostering underground networks that symbolized broader societal dissent. The dictatorship's end in 1985 marked redemocratization, with the of civilian signaling a peaceful and the restoration of across the region. In the 1990s, the Real Plan's economic stabilization under President curbed and spurred GDP growth, particularly benefiting the Southeast's industrial base through increased investment and export competitiveness. This period saw the region's GDP expand at rates above the national average, reinforcing its role as Brazil's economic engine. Major events like the , hosted across multiple Southeast cities including and Rio de Janeiro, and the 2016 Rio Olympics accelerated infrastructure projects but also highlighted fiscal strains and uneven social benefits. The 2020s brought challenges from , intensified by the 2022 presidential elections, where the Southeast showed divided support—Lula da Silva won in and , while prevailed in and Rio de Janeiro—exacerbating regional tensions over policy and governance. The further tested the region, which reported approximately 45% of Brazil's total cases (over 15 million out of about 34 million by late 2022) due to its dense urban populations, though it achieved high vaccination rates, with coverage exceeding 80% for primary doses by 2022. Post-2000 efforts, including coordination through initiatives like the Initiative for the Integration of the Regional Infrastructure of (IIRSA), have focused on harmonizing projects such as highways and ports to enhance connectivity across the Southeast states.

São Paulo, the economic hub of the region and the nation, drives much of Brazil's industrial and financial activity through its capital city, which accounts for over 30% of the country's GDP. Rio de Janeiro served as Brazil's federal capital from 1763 until 1960, when the seat of government transferred to , leaving a legacy as a cultural and administrative center. functions as a key mining center, anchoring ' role as Brazil's leading producer of and other minerals. Vitória acts as a vital port gateway for the region, facilitating exports of and other commodities through the Port of Vitória, one of Brazil's major maritime outlets.

Political Structure

The Southeast Region of Brazil is deeply integrated into the nation's federal , with its four states—São Paulo, , Rio de Janeiro, and —collectively electing 179 members to the , representing approximately 35% of Brazil's total 513 federal deputies based on population proportions. This allocation includes 70 deputies from São Paulo, 53 from , 46 from Rio de Janeiro, and 10 from . Additionally, the region holds 12 seats in the Federal Senate, with each state electing three senators for staggered eight-year terms to ensure balanced representation across the federation. At the state level, governance follows a presidential model mirroring the federal structure, where each state elects a and members of a unicameral for four-year terms, with elections held concurrently every four years. As of 2025, the current governors, elected in 2022, include (Republicans) in , () in , (Liberal Party) in Rio de Janeiro, and Renato Casagrande () in . These executives oversee state policies on education, health, and security, while vary in size: 's has 94 deputies, 77, Rio de Janeiro 70, and 30, all elected via to legislate on state matters and oversee the executive. Regional politics in the Southeast exhibit a strong center-right orientation, influenced by historical dominance of parties like the Brazilian Social Democracy Party (PSDB) in states such as , though recent shifts have seen the rise of newer conservative groups like and the Liberal Party. The 2024 municipal elections reinforced this trend overall, with center-right candidates securing victories in major cities like , where Mayor Ricardo Nunes (Liberal Party) was reelected, but showed progressive undercurrents in Rio de Janeiro, where incumbent (Social Democratic Party) won a fourth non-consecutive term with 60.26% of the vote in the first round, defeating a Bolsonarista challenger and signaling a away from far-right extremes. Key challenges in the region's political landscape include lingering effects of corruption scandals, notably Operation Lava Jato (2014–2021), which exposed widespread graft involving politicians and executives in states like Rio de Janeiro and , leading to impeachments, convictions, and economic disruptions that eroded and reshaped party alignments into the . Federal-regional tensions also persist over , particularly in fiscal transfers and funding, where Southeast states often advocate for greater autonomy amid disputes with the central government on and environmental regulations.

Ethnic and Racial Groups

The ethnic and racial composition of Brazil's Southeast Region reflects a complex history of colonization, slavery, and immigration, resulting in a diverse population as captured by the 2022 Brazilian Census conducted by the Instituto Brasileiro de Geografia e Estatística (IBGE). According to this census, the region is predominantly White (49.9%) and Pardo (mixed-race, 38.7%), with smaller proportions identifying as Black (10.6%), Asian or Yellow (0.7%), and Indigenous (0.1%). The Southeast stands out nationally for having the highest share of Asian-descent residents, largely attributable to Japanese communities concentrated in São Paulo state. These self-identified categories highlight the fluidity of racial identities in Brazil, where intermixing has long been prevalent, though socioeconomic disparities persist across groups. The demographic makeup traces its roots to the colonial era, when settlers formed the foundational European population in the region. Beginning in the early , expeditions led by figures like established coastal settlements, such as São Vicente in 1532, which evolved into key centers in present-day and Rio de Janeiro; by the late 1500s, these outposts supported sugar plantations and trade, drawing around 300,000 migrants over three centuries to as a whole, with a focus on the Southeast's fertile lands. This European base was augmented by the forced arrival of millions of enslaved Africans, who comprised about 40% of all captives brought to the via the transatlantic slave trade; imported approximately 4.9 million Africans between 1501 and 1866, with major ports like Rio de Janeiro receiving over 1.5 million, fueling mining in and in and Rio de Janeiro. Mass immigration from and further shaped the region's diversity between 1880 and 1930, as Brazil sought to "whiten" its population and bolster its workforce post-abolition in 1888. Around 4 million Europeans arrived nationwide during this period, including over 1.5 million who settled primarily in São Paulo's coffee farms and 200,000 who established communities in and ; these groups integrated through intermarriage, contributing to the high and proportions today. Japanese immigration, beginning in 1908 with the arrival of 781 workers at Santos port in São Paulo, grew to about 190,000 by 1941 and reached 1.5 million descendants by the late , mostly in urban São Paulo, where they formed agricultural cooperatives and later professional networks. Regional variations underscore this layered history. In São Paulo state, the population is approximately 60% White, 30% Pardo, 8% Black, 1% Asian, and less than 1% Indigenous, reflecting heavy European and Japanese influences amid ongoing internal migration. Minas Gerais shows a more balanced mix at about 44% White, 45% Pardo, 11% Black, with minimal Asian (0.1%) and Indigenous (0.5%) shares, tied to its mining-driven colonial slave economy and later Italian influxes. Rio de Janeiro state has around 42% White, 42% Pardo, and 16% Black residents, with Afro-Brazilian heritage prominent due to its role as a primary slave entry point, alongside smaller Asian (0.2%) and Indigenous (0.2%) groups. Espírito Santo exhibits higher Pardo (50%) and lower White (39%) percentages, with 11% Black, shaped by German and Italian farming settlements in the 19th century. These differences influence local social dynamics, fostering syncretic identities such as Carioca culture in Rio de Janeiro, which fuses Portuguese, African, and Indigenous elements in music, dance, and daily life.

Secondary and Tertiary Sectors

The Southeast Region of Brazil stands as the nation's industrial epicenter, with the secondary sector encompassing manufacturing that accounts for a substantial portion of the country's output. São Paulo State hosts over 40% of 's automotive plants, making it the largest hub for vehicle production and assembly, where companies like operate major facilities contributing to the sector's role in generating approximately 22% of 's industrial GDP. In , , headquartered and primarily based in São José dos Campos, São Paulo, leads global production of commercial jets, executive aircraft, and defense systems, leveraging the region's skilled workforce and technological infrastructure. manufacturing is prominent in Rio de Janeiro, where , the state-owned giant, drives refining and chemical production as part of its extensive operations in the state, supporting downstream industries across . The tertiary sector overwhelmingly dominates the region's economy, contributing around 70% to its GDP through services that underscore Brazil's financial and tourism prowess. São Paulo's B3 stock exchange handles approximately 85% of the nation's equity trading volume, serving as the primary platform for capital markets and attracting international investment with daily trades exceeding R$25 billion. Tourism bolsters this dominance, particularly in Rio de Janeiro, which welcomed 1.19 million international visitors in 2023 and generated R$14.5 billion in the first half of 2025 alone from attractions like the Christ the Redeemer statue, a UNESCO World Heritage site drawing millions annually for its cultural and panoramic significance. Emerging technology hubs further enhance the tertiary landscape, with Campinas in São Paulo State often dubbed the "Silicon Valley of Brazil" for hosting 32 of the world's 500 largest IT firms and fostering innovation in software, data centers, and R&D through partnerships with universities like the University of Campinas. Overall, the secondary sector comprises about 25% of the region's GDP, while the tertiary sector's expansion has driven post-COVID tourism recovery to 95% of pre-2019 levels by 2025, with international arrivals surpassing 7 million nationwide in the first nine months of the year. This sectoral balance positions the Southeast as a key driver of Brazil's economy, contributing 53% of the national GDP.

Culture

Cultural Heritage

The Southeast Region of Brazil boasts a rich shaped by its colonial past, indigenous influences, and waves of European and African immigration, manifesting in distinctive artistic, literary, and musical traditions. This legacy is evident in the modernist innovations of the early and the preservation of historical sites that reflect the region's role in Brazil's era. Key contributions include groundbreaking literary works from Rio de Janeiro and , musical genres born in urban and rural settings, and that blend global and local elements to assert a uniquely Brazilian identity. In the realm of arts and literature, the 1922 Semana de Arte Moderna in marked a pivotal moment, launching Brazil's modernist movement by challenging European artistic norms through exhibitions, poetry readings, music, and dance at the city's Municipal Theater from February 13 to 17. Organized by figures like painters and poets and , the event promoted a cultural independence that integrated Brazilian themes with avant-garde experimentation, influencing generations of artists across the Southeast. Prominent authors from the region further enriched this tradition; Joaquim Maria Machado de Assis, born in Rio de Janeiro's Livramento neighborhood in 1839 to a family of mixed African and Portuguese descent, penned realist novels like (1899) that critiqued 19th-century Brazilian society with irony and psychological depth, establishing him as a foundational voice in national literature. Similarly, , born in 1908 in Cordisburgo, , revolutionized prose with works like Grande Sertão: Veredas (1956), employing neologisms and regional dialects to explore the existential landscapes of the Brazilian hinterland, drawing from his upbringing in the state's rural interior. Music in the Southeast reflects a fusion of African rhythms, European harmonies, and local innovations, with Rio de Janeiro as a central hub. Samba emerged in the city's Afro-Brazilian communities during the late 19th and early 20th centuries, evolving from rural forms like the UNESCO-recognized Samba de Roda of Bahia's Recôncavo region (inscribed in 2005 as ) through migration and urbanization, becoming synonymous with and social commentary by the 1920s. In the 1950s, arose in Rio's Copacabana neighborhood, pioneered by composer , who blended samba's syncopation with cool jazz influences to create intimate, melodic songs like "The Girl from Ipanema" (1962), capturing the era's urban sophistication and achieving global acclaim. , originating in Northeast Brazil's but gaining traction in ' interiors through mid-20th-century migration and media, features accordion-driven rhythms and dances that evoke rural life, with dedicated forró houses proliferating in the state by the 1970s as a bridge between northeastern traditions and southeastern audiences. Historical sites in the region preserve the architectural splendor of Portugal's colonial era, particularly tied to the 18th-century gold trade. Ouro Preto in Minas Gerais, a former mining capital founded in the late 17th century, exemplifies Baroque colonial architecture with its ornate churches, sculptures by Antônio Francisco Lisboa (Aleijadinho), and street layouts that earned it UNESCO World Heritage status in 1980 for representing Brazil's mining heritage and artistic peak. Likewise, Paraty in Rio de Janeiro state, established as a 17th-century port for exporting gold along the Caminho do Ouro route, features well-preserved colonial buildings, cobblestone streets, and fortified defenses that highlight its role in Atlantic trade, leading to its inscription as a UNESCO World Heritage site in 2019 under the title "Paraty and Ilha Grande – Culture and Biodiversity." Visual arts in the Southeast advanced through the modernist lens, notably via , a São Paulo-based painter active in the 1920s Anthropophagic Movement. Her 1929 painting Antropofagia embodies the concept of cultural cannibalism—articulated in Oswald de Andrade's 1928 —as a metaphor for devouring foreign influences to forge a Brazilian aesthetic, featuring surreal, indigenous-inspired figures that critique and celebrate hybridity, solidifying her role in the Semana de Arte Moderna's legacy.

Cuisine and Festivals

The cuisine of Southeast Brazil embodies a fusion of indigenous, Portuguese, African, and later immigrant traditions, resulting in hearty, flavorful dishes that vary by state and landscape. Feijoada, a rich black bean stew simmered with pork cuts like ears, tails, and sausages, traces its origins to Rio de Janeiro, where enslaved Africans adapted Portuguese cooking techniques using available ingredients during the colonial era. This dish, often served with rice, collard greens, and orange slices, symbolizes communal meals and is traditionally prepared on weekends. In Minas Gerais, pão de queijo—small, gluten-free cheese breads made from cassava flour and Minas cheese—emerged on 18th-century farms, where enslaved laborers and colonists baked them as a staple using local tubers and dairy. Espírito Santo contributes moqueca capixaba, a seafood stew of fish or shrimp cooked in a clay pot with tomatoes, cilantro, and palm oil, distinct from Bahia's version by its lighter, red palm-free preparation that highlights coastal marine bounty.
