The Acolapissa were a small tribe of Native Americans of North America, who lived in the Southeast of what is the present-day United States.
Shortly afterward, Louis Juchereau de St. Denis sent the Natchitoches tribe to live with the Acolapissa, who welcomed them and allowed them to settle close to their own village.
Pressured by French settlement in the area and suffering high mortality from new infectious diseases carried by the Europeans, the Acolapissa tribe eventually merged with the Bayogoula.
However the research by anthropologist James Mooney in the 20th century determined that a more accurate count was proposed by Jean-Baptiste Bénard de la Harpe, who found that the tribe population was around 1500 people.
[6][7] Other spelling versions of the tribe's name included: Aquelou pissas (a French transliteration),[8] Quinipissa, Cenepisa,[9] Colapissa,[10] Coulapissa,[10] Equinipicha, Kinipissa, Kolapissa,[11] and Mouisa.
