Tupi-Sprache
Also during the mid 18th century, however, the indigenous population then faced a sharp decline due to disease, being forced into hard labour and being oppressed by their Portuguese colonisers. There was an active push by the colonisers to increase the Portuguese presence: villages were eradicated along the Amazon, and there was an effort to replace Língua Geral Amazônica with Portuguese. There were different varieties of Tupinambá within the different communities along the Amazon, but these varieties were largely replaced by Portuguese at the beginning of the 19th century. 1822 marked Brazil’s independence; after which there was a large revolt, called the Cabanagem, against the Europeans. This involved Indians, caboclos and blacks, over a decade, and much blood was shed. 40,000 lives were lost; all of which were from the Nheengatu-speaking community. With the increase in immigration due to urbanization, remaining speakers of Língua Geral Amazônica, or Nheengatu, were pushed to more remote areas in western Amazonia. Linguistic documents were also published during this time, due to increased interest in Nheengatu.
