The Tariana or Taliaseri are an indigenous people of the Vaupés or Uaupés River in the Amazon region of Brazil and Colombia. Starting in the 19th century missionaries tried to persuade them to abandon their traditional beliefs and practices, with some level of success. The government made efforts to convert them to a "colony" system in exchange for health, education and economic benefits starting in the 1980s. They are now relatively autonomous within several indigenous territories.
