イエズス会伝道所
Bolaños was ordained a priest in 1585. For fifty more years he worked on the evangelization of the Guaraní aboriginals. He created the system of reductions, settlements populated by natives and overseen by the friars of the Order, of which the Jesuit Reductions would then become their most renowned examples. These towns "reduced" the originally nomadic natives to fixed, stable locations, allowing the missionaries to better control and catechize them, while teaching them to read and write, to cultivate the land, to domesticate animals, and to create manual artistic works. The Franciscan friar founded reductions all over the basin of the Paraná River, in Paraguay, large parts of Brazil, and the Argentine provinces of Misiones and northern Corrientes.
