The Jesuit missions among the Guaraní were a type of settlement for the Guaraní people ("Indians" or "Indios") in an area straddling the borders of present-day Argentina, Brazil and Paraguay (the triple frontier). The missions were established by the Jesuit Order of the Catholic Church early in the 17th century and ended in the late 18th century after the expulsion of the Jesuit order from the Americas. The missions have been called an experiment in "socialist theocracy" or a rare example of "benign colonialism". Others have argued that "the Jesuits took away the Indians' freedom, forced them to radically change their lifestyle, physically abused them, and subjected them to disease".
In their newly acquired South American dominions, the Spanish and Portuguese Empires adopted a strategy of gathering native populations into communities called "Indian reductions" (Spanish: reducciones de indios, Portuguese: reduções). The objectives of the reductions were to impart Christianity and European culture. Secular as well as religious authorities created "reductions".
