About Rio Grande do Sul
Rio Grande do Sul (UK: , US: , Brazilian 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.

Rio Grande do Sul in Depth
History
During the Brazilian Colonial period, the province of South Rio Grande was the scene of small wars and border skirmishes between Portugal and Spain for the region, the Sacramento Colony, and the Guarani Missions. It was also a focal point for internal rebellions in the 19th and the early 20th centuries.
According to the treaty of Tordesillas, the region was to be part of the Spanish possessions in South America. However, the Spanish were much more interested in the Pacific Coast, where gold, silver, and gems were quickly found. Even on the Atlantic coast, their attention was on the River Plate where they built the seaport of Buenos Aires, on its right bank.
Geography
Rio Grande do Sul is bordered to the northeast by the Brazilian State of Santa Catarina, to the southeast by the Atlantic Ocean, on the southwest by Uruguay, and to the northwest by the Argentine provinces of Corrientes and Misiones.
The northern part of the state lies on the southern slopes of the elevated plateau extending southward from São Paulo across the states of Paraná and Santa Catarina, and is much broken by low mountain ranges whose general direction across the trend of the slope gives them the appearance of escarpments. A range of low mountains extends southward from the Serra do Mar of Santa Catarina and crosses the state into Uruguay.
Economy
The industrial sector is the largest component of GDP at 43%, followed by the service sector at 41%. Agriculture represents 16% of GDP (2004). Rio Grande do Sul exports: footwear 18%, soybeans 14%, tobacco 13.6%, vehicles 8%, frozen meat 7.2%, chemicals 6.8%, and leather 5% (2002).
One of the most prosperous Brazilian states, Rio Grande do Sul is known especially for its grain production, viticulture, ranching, and for its considerable industrial output.
In 1827, emigrants from Idar-Oberstein discovered the world's most important agate deposit in Rio Grande do Sul. As early as 1834, the first delivery of agate from Rio Grande do Sul had been made to Idar-Oberstein. The Brazilian agate exhibited very even layers, much more even than those seen in the local agates.
Demographics
According to the IBGE of 2022, there were 10,882,965 people residing in the state. The population density was 38.63 inhabitants per square kilometre (100.1/sq mi).
Urbanization: 81% (2004); population growth: 1.2% (1991–2000); houses: 3,464,544 (2005).
