The Atakapa also known as "The People". They were a Southeastern culture of Native American tribes with a common language who lived along the Gulf of Mexico. They lived in rivers valleys, lake shores, and coasts from Galveston Bay, Texas to Vermilion Bay, Louisiana.
After 1762, when Louisiana was transferred to Spain, little was written about the Atapakans. Epidemics of the late 18th century reduced their numbers considerably. Survivors joined the Caddo, Koasati, and other surrounding tribes, although some culturally distinct Atakapan people survived into the 20th century.
