Tupi-Sprache
The existence of Portuguese in Brazil is a legacy of the Portuguese colonization of the Americas. The first wave of Portuguese-speaking immigrants settled in Brazil in the 16th century, but the language was not widely used then. For a time Portuguese coexisted with Língua Geral—a lingua franca based on Amerindian languages that was used by the Jesuit missionaries—as well as with various African languages spoken by the millions of slaves brought into the country between the 16th and 19th centuries. By the end of the 18th century, Portuguese had affirmed itself as the national language. Some of the main contributions to that swift change were the expansion of colonization to the Brazilian interior, and the growing numbers of Portuguese settlers, who brought their language and became the most important ethnic group in Brazil.
