South Region, Brazil in the context of "Southeast Region, Brazil"

Portuguese is the official and national language of Brazil, being widely spoken by nearly all of its population. Brazil is the most populous Portuguese-speaking country in the world, with its lands comprising the majority of Portugal's former colonial holdings in the Americas.

Aside from Portuguese, the country also has numerous minority languages, including over 200 different indigenous languages, such as Nheengatu (a descendant of Tupi), and languages of more recent European and Asian immigrants, such as Italian, German and Japanese. In some municipalities, those minor languages have official status: Nheengatu, for example, is an official language in São Gabriel da Cachoeira, while a number of German dialects are official in nine southern municipalities.

Italian Brazilians (Italian: italo-brasiliani, Portuguese: ítalo-brasileiros) are Brazilians of full or partial Italian descent, whose ancestors were Italians who emigrated to Brazil during the Italian diaspora, or more recent Italian-born people who've settled in Brazil. Italian Brazilians are the largest number of people with full or partial Italian ancestry outside Italy, with São Paulo being the most populous city with Italian ancestry in the world. Nowadays, it is possible to find millions of descendants of Italians, from the southeastern state of Minas Gerais to the southernmost state of Rio Grande do Sul, with the majority living in São Paulo state. Small southern Brazilian towns, such as Nova Veneza, have as much as 95% of their population of Italian descent.

There are no official numbers of how many Brazilians have Italian ancestry, as the national census conducted by IBGE does not ask the ancestry of the Brazilian people. In 1940, the last census to ask ancestry, 1,260,931 Brazilians were said to be the child of an Italian father, and 1,069,862 said to be the child of an Italian mother. Italians were 285,000 and naturalized Brazilians 40,000. Therefore, Italians and their children were, at most, just over 3.8% of Brazil's population in 1940.

German Brazilians (German: Deutschbrasilianer, Hunsrik: Deitschbrasiliooner, Portuguese: teuto-brasileiros) refers to Brazilians of full or partial German ancestry. German Brazilians live mostly in the country's South Region, with a smaller but still significant percentage living in the Southeast Region.

Between 1824 and 1972, about 260,000 Germans settled in Brazil, the fifth largest nationality to immigrate after the Portuguese, the Italians, the Spanish, and the Japanese. By 1940, the German diaspora in Brazil totaled about a million.

Santa Catarina (Brazilian Portuguese: [ˈsɐ̃tɐ kataˈɾĩnɐ] ; English: /ˈsæntə ˌkætəˈriːnə/) is one of the 27 federative units of Brazil. It is located in the centre of the country's Southern region. It is bordered to the north by the state of Paraná, to the south by the state of Rio Grande do Sul, to the east by the Atlantic Ocean, and to the west by the Argentine province of Misiones.

The state covers an area of approximately 95,730.69 square kilometres (37,000 sq mi), comparable to Hungary, and ranking as the seventh smallest Brazilian state by area. With a population of 7.6 million inhabitants in 2022, it is the tenth most populous state in Brazil. It is divided into 295 municipalities and its capital is Florianópolis, the second most populous city in the state after Joinville. Alongside Espírito Santo, Santa Catarina is one of the two states whose capital is not the largest city. Jorginho Mello, a member of the conservative Liberal Party, has been the governor of the state since 2023.

Brazilian German is a set of languages, spoken by German Brazilians, High German and Low German, together form a significant minority language in Brazil. "Brazilian German" is strongly influenced by Portuguese and to a lesser extent by Italian dialects as well as indigenous languages. High German and Low Saxon/Low German dialects and other Germanic languages are particularly strong in Brazil's South and Southeast Regions.

German speakers from Germany, Switzerland and Austria make up the largest group of immigrants after Portuguese and Italian speakers. They tended to preserve their language longer than the speakers of Italian, which is closer to Portuguese. Consequently, German and Low Saxon/German was the second most common family language in Brazil at the 1940 census. However, even in areas that are still dominated by German speakers, most are bilingual. Today, (Low-) German is increasingly cultivated as a cultural heritage, and several municipalities have recently given co-official status with Portuguese to one Brazilian variant or another of it.

Curitiba (Brazilian Portuguese: [kuɾiˈtʃibɐ]; English: /ˌkʊərɪˈtʃiːbə/ KOOR-ih-CHEEB-ə) is the capital and largest city in the state of Paraná in Southern Brazil. The city's population was 1,829,225 as of 2024, making it the eighth most populous city in Brazil and the largest in Brazil's South Region. The Curitiba Metropolitan area comprises 29 municipalities with a total population of over 3,559,366, making it the ninth most populous metropolitan area in the country.

The city sits on a plateau at 932 m (3,058 ft) above sea level. It is located west of the seaport of Paranaguá and is served by the Afonso Pena International and Bacacheri airports. Curitiba is an important cultural, political, and economic center in Latin America and hosts the Federal University of Paraná, established in 1912.

Rio Grande do Sul (UK: /ˌriːuː ˌɡrændi duː ˈsʊl/, US: /- ˌɡrɑːndi duː ˈsuːl/; Portuguese: [ˈʁi.u ˈɡɾɐ̃dʒ(i) du ˈsuw] ; lit. "Great River of the South") is a state in the southern region of Brazil. It is the fifth-most populous state and the ninth-largest by area and it is divided into 497 municipalities. Located in the southernmost part of the country, Rio Grande do Sul is bordered clockwise by Santa Catarina to the north and northeast, the Atlantic Ocean to the east, the Uruguayan departments of Rocha, Treinta y Tres, Cerro Largo, Rivera, and Artigas to the south and southwest, and the Argentine provinces of Corrientes and Misiones to the west and northwest. The capital and largest city is Porto Alegre. The state has the highest life expectancy in Brazil, and the crime rate is relatively low compared to the Brazilian national average. The state has 5.4% of the Brazilian population and it is responsible for 6.6% of the Brazilian GDP.

The state shares a gaucho culture with its neighbors Argentina and Uruguay. Before the arrival of Portuguese and Spanish settlers, it was inhabited mostly by the Guarani and Kaingang peoples (with smaller populations of Charrúa and Minuane). The first Europeans there were Jesuits, followed by settlers from the Azores. In the 19th century it was the scene of conflicts including the Ragamuffin War and the Paraguayan War. Large waves of German and Italian migration have shaped the state as well.

Acre (Portuguese: [ˈakɾi] ) is a state located in the west of the North Region of Brazil and the Amazonia Legal. Located in the westernmost part of the country, at a two-hour time difference from Brasília, Acre is bordered clockwise by the Brazilian states of Amazonas and Rondônia to the north and east, along with an international border with the Bolivian department of Pando to the southeast, and the Peruvian regions of Madre de Dios, Ucayali and Loreto to the south and west. Its capital and largest city is Rio Branco. Other important places include Cruzeiro do Sul, Sena Madureira, Tarauacá and Feijó. The state, which has 0.42% of the Brazilian population, generates 0.2% of the Brazilian GDP.

Intense extractive activity in the rubber industry, which reached its height in the early 20th century, attracted Brazilians from many regions to the state. From the mixture of sulista, southeastern Brazil, nordestino, and indigenous traditions arose a diverse cuisine.
