São Francisco River
History

Tuxá, Truká, Natú, Kariri languages, eastern Maxakalían languages, Jê languages, and various unclassified extinct languages were spoken in the São Francisco River basin.

The Italian explorer Amerigo Vespucci first saw the river on 4 October 1501. In 1865 the British explorer and diplomat Richard Francis Burton was transferred to Santos in Brazil. He explored the central highlands, canoeing down the São Francisco river from its source to the falls of Paulo Afonso.
