Missions in the "Banda Oriental" in southern Brazil. The "Banda Oriental" was finally divided by the Treaty of San Ildefonso in 1777 between Spanish and Portuguese domains, the western portion becoming part of what is today state of Rio Grande do Sul, Brazil, the eastern portion becoming part of what is today Uruguay.
There were also 7 Spanish Missions (out of 30 or so in Viceroyalty of Peru east of the Andes)
constructed along tributaries in the Upper Solimoes area of what later became State of Amazonas, Brazil, between 1686 and 1689 by Jesuit Padre Samuel Fritz among the Omagua indigenous peoples.
Some of these were moved upstream into Peru due to pressure from the "Bandeirantes" slave raiders; the rest were destroyed by Portuguese forces between 1700 and 1711.
