Guató people
The Guató are a nomadic Native American tribe of South America that live along the Paraguay River, along the border of modern-day Brazil and Bolivia. They aided the Brazilians in the war with Paraguay 1865-70.
A movie about the Guatós was recently released: "[500 Almas]" ("500 Souls") - which is named after the approximate number of Guatós left.
