The Charrua are an indigenous people of southern South America in Argentina. Historically they had lived in Uruguay and southern Brazil. They were a nomadic people that sustained themselves through fishing and foraging. They did not build permanent structures, living instead in tents. The Charrua are thought to have been driven south into present day Uruguay by the Guarani people around 4000 years ago. The Charrua killed Spanish explorer Juan Diaz de Solis during his 1515 voyage up the Rio de la Plata. Following the arrival of European settlers, the Charrua were progressively killed by or integrated into the prevailing colonial cultures. Most of the remaining ones were massacred at Salsipuedes (literally "Get-out-if-you-can") Creek on 11 April 1831 by a group led by Bernabe Rivera, nephew of Fructuoso Rivera who later became the first president of Uruguay. Bernabe Rivera had invited the Charrua to a meeting, then ambushed them.
