The Yatasi were a Native American people of northeastern Louisiana, part of the Natchitoches Confederacy of the Caddo Nation. They who lived in the area to the south of modern Shreveport prior to the European incursion into the area. In 1686, French explorer Henry de Tonti visited Yatasi settlements on the Red River. They welcomed the French expedition but did not provide him with guides. At the time, the Yatasi were fighting the Kadohadacho. In the early 18th century, the Chickasaw tribe fought with Yatasi and killed a great number of them. With their numbers reduced, they joined the Ouachita, Doustioni, and Natchitoches Indians at the Natchitoches trading depot. During this time the Yatasi traded with the French, the later the Spanish. The Yatasi provided bear fat and buffalo and deer hides for cloth, blankets, metal tools and weapons, combs, glass beads, flints, ammunition, vermillion dye, mirrors, and copper.
