Tupi-Sprache
When the Jesuits were expelled from the Spanish realm in 1767, the reductions slowly died out, becoming victims of slave raids or being absorbed into European society. Some of the reductions have continued to be inhabited as towns while most have been abandoned and remain only as ruins. Córdoba, Argentina, the largest city associated with the reductions, was atypical as a Spanish settlement that predated the Jesuits and functioned as a centre for the Jesuit presence, with a novitiate centre and a college that is now the local university. The Córdoba mission was taken over by the Franciscans in 1767. Many have been declared UNESCO World Heritage sites, including six of the Jesuit Missions of Chiquitos in Bolivia, and others in Brazil, Argentina, and Paraguay. There are also two creole languages, Língua Geral and Nheengatu, originating in the reductions and based on Guaraní, Tupi, and Portuguese.
