Rio Grande do Sul instance of federative unit of Brazil
Rio Grande do Sul (UK: , US: , Portuguese: [ˈʁi.u ˈɡɾɐ̃dʒ(i) du ˈsuw] (listen); 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. 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. Despite the high standard of living, unemployment is still high in the state, as of 2017. 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.Cisplatine War
The districts of Santa Catarina and Rio Grande had been separated in 1760 for military convenience, and in 1807 the latter was elevated to the category of a "capitania-geral", with the designation of "Sao Pedro do Rio Grande", independent of Rio de Janeiro, and with Santa Catarina as a dependency. In 1812 Rio Grande and Santa Catarina were organized into two distinct comarcas, the latter becoming an independent province in 1822 when the Empire of Brazil was organized.
In 1816, the Portuguese captured Uruguay, which became a Province of Brazil (Província Cisplatina). This situation outlasted Brazil's independence from Portugal in 1822; in 1825, however, Juan Antonio Lavalleja proclaimed the independence of Uruguay; war followed, until in 1828 Brazil recognized Uruguayan independence.
