Língua Geral of São Paulo

The Língua Geral Paulista (Paulista General language), or Tupi Austral (Southern Tupi), was a Tupi-based trade language of São Vicente and the upper Tietê River, in the Brazilian state of São Paulo. In the 17th century, it was widely spoken in the municipality São Paulo and spread to neighboring regions. Starting in 1750, orders from Marquis of Pombal forced Portuguese to be taught to Paulista children in schools. Língua Geral Paulista subsequently lost ground to Portuguese and eventually became extinct.
