Bororo
Bororo, a large Brazilian nation occupying the whole region between Cuyaba and Goyaz. The Bororo were lately visited by Dr. Ehrenreich during his journey from Paraguay to the Amazon river, and are described by him in the Berlin Geographical Society's Proceedings for November, 1889. They are the chief nation in Matto-Grosso, and formerly ruled over a vast territory, but were reduced about the middle of the 17th century by Antonio Pires de Campo, who founded Santa Anna, Lonhosa, and other settlements in their domain. They were afterwards utilised to suppress the marauding expeditions of their hereditary foes, the powerful Cayapos of the Upper Parana basin.
