Minas Gerais

Minas Gerais is a state in Brazil’s Southeast Region, ranking as the country’s fourth largest by area and second most populous, with 20,539,989 residents as of the 2022 census. Its capital, Belo Horizonte, is the sixth largest city in Brazil and a key urban and financial hub; its metropolitan area, with just over 5.8 million people, is the third largest in the nation, trailing only São Paulo and Rio de Janeiro. The state is divided into 853 municipalities—more than any other Brazilian state.

The terrain is rugged, containing some of Brazil’s highest peaks and the headwaters of major rivers like the São Francisco, Grande, Paranaíba, Doce, and Jequitinhonha, giving it a strategic role in the country’s water resources. Its tropical climate ranges from cooler, humid conditions in the south to semi-arid in the north, supporting rich wildlife and plant life across biomes such as the Cerrado and the threatened Atlantic Forest.

Indigenous peoples lived in the area before Portuguese arrival. A gold rush in the late 17th century triggered a large migration, bringing wealth and development to the then captaincy. When gold dwindled, many left, but a coffee cycle later restored the state’s national prominence, eventually giving way to relatively late industrialization. Today, Minas Gerais has Brazil’s third largest GDP, with mining still a major contributor. It also boasts extensive infrastructure, including many hydroelectric plants and the country’s largest road network.

The state is a major tourist destination, known for colonial architecture and art in historic towns like Ouro Preto, Diamantina, São João del-Rei, Mariana, Tiradentes, Congonhas, Sabará, and Serro. In the south, attractions include hydro-mineral spas in Caxambu, Lambari, São Lourenço, Poços de Caldas, São Thomé das Letras, and Monte Verde, plus the Caparaó and Canastra national parks. Caves and waterfalls draw visitors to Serra do Cipó, Sete Lagoas, Cordisburgo, and Lagoa Santa. The culture is distinct, marked by traditional religious festivals, countryside cuisine, and notable contributions to contemporary art and sports.

The name “Minas Gerais” has two possible origins. One interpretation is simply “General Mines,” referencing multiple mining areas. Another traces it to the colonial province “Minas dos Matos Gerais” (“Mines of the General Woods”), which distinguished the mining region from the “general” region of sertão far from the mines.

The state’s history has been shaped by mineral wealth, with mining starting in the 17th century and remaining economically important. Prehistoric human presence is attested by the Luzia woman, the oldest human fossil found in the Americas, discovered in 1974 in a cave near Lagoa Santa and Pedro Leopoldo, estimated to be 11,400 to 12,000 years old. Danish paleontologist Peter Wilhelm Lund found remains of the “Lagoa Santa People” in the mid-19th century. Early theories, based on cranial shape, suggested Luzia’s people had Australoid features and arrived before Amerindian ancestors, but genetic analysis later showed they had entirely Amerindian DNA, ruling out an Australasian connection. Indigenous peoples of Minas Gerais, like those across Brazil and South America, descend from groups that migrated through North America. Archaeological sites in northern municipalities like Januária, Montalvânia, Itacarambi, and Juvenília indicate settlement dating to Luzia’s era, with emerging cultural traits such as stone and bone tools, cemeteries, and small grain cultivation.
