Beginning in the early 18th century, Portugal's government made efforts to expand the use of Portuguese throughout the colony, particularly because its consolidation in Brazil would help guarantee to Portugal the lands in dispute with Spain (according to various treaties signed in the 18th century, those lands would be ceded to the people who effectively occupied them). Under the administration of the Marquis of Pombal (1750–1777), Brazilians started to favour the use of Portuguese, as the Marquis expelled the Jesuit missionares (who had taught Língua Geral) and prohibited the use of Nhengatu, or Lingua Franca.
