Ava

The Guaraní were related indigenous peoples living between the Paraná and Paraguay rivers and across parts of southern Brazil. Their villages grew manioc and maize, and families shared large communal houses under local chiefs.

In the early seventeenth century Jesuits established missions among the Guaraní. The 1750 Treaty of Madrid ordered seven missions east of the Uruguay River to move; their inhabitants resisted under Sepé Tiaraju, but Spanish and Portuguese forces defeated them at Caiboaté in 1756.
