Adai Indians
The Adai tribe, initially thought to be an independent linguistic group, was later identified as part of the Caddoan stock. Located near present-day Robeline in Natchitoches Parish, the Adai encountered Spanish missionaries in the early 18th century. Despite rebuilding their mission after its destruction in 1719, the Adai population dwindled over time, with reports of a small settlement as late as 1805. Their unique dialect distinguished them within the Caddoan tribes, and they served as a strategic outpost for Spanish colonial efforts in Texas.
