The Chaouacha were an indigenous people in Louisiana, best known in history for being the victims of a massacre in retaliation for the Natchez revolt on French colonists in which they had had no part. When first described, they lived on the east bank of the Mississippi River, just south of New Orleans. Following an attack by the Natchez on Fort Rosalie, colonists feared of an Indian rebellion, or even worse a combined Indian and slave revolt. Governor of Louisiana Étienne Périer ordered a force of black slaves to massacre the Chaouacha community. In 1699 they were reported to be allied with the Ouacha/ Washa and the Opelousa. An 1802 mention by French colonist Baudry de Lozières describes them as "Tchaouachas: Reduced to 40 warriors. A wandering indolent and lazy nation, settled near the French in 1712. Corn is the only assistance one can expect of them."
