In Brazil, Jesuits spent two centuries protecting Indigenous people from colonists while gathering them into mission villages and inventing a common language to convert them. Pombal then expelled the Jesuits in 1759 and banned Indigenous languages. The episode runs through the rubber boom to today's evangelical efforts to contact uncontacted peoples, set against Brazil's no-contact policy.
The Jesuits fought Indigenous enslavement yet the aldeias also controlled Indigenous life and profited from their labor. The missionaries cite the Gospel and material aid, while evidence and Brazilian state policy hold that contact brings lethal epidemics. How much Língua Geral survived Pombal's ban is also debated.
