ABSTRACT
The area the present-day Guaraní inhabit is much smaller than the area they inhabited in the 1500s, when they first encountered Europeans. Because of the activities of Jesuits, who gathered Guaraní people from various localities and put them in the same mission towns (reducciónes ‘reductions’), and the genetic mixing of the Guaraní with Europeans, subtribes mentioned by Spanish conquistadors and missionaries have disappeared.
