Possibly as many as 600 Native American groups were populating what is now central and southern Texas and northeastern Mexico when the Spanish invaders first arrived. Some historians erroneously report that these bands “disappeared”. The Indigenous Cultures Institute is a nonprofit organization dedicated to actively preserve the culture of this population, collectively known as Coahuiltecans. The Institute presents educational programs on the identity and ancestral legacy of these Native Americans who may have millions of descendants living in Texas and the U.S. Many of these descendants continue to practice their Indigenous ceremonies, pray in their Native languages, and hold true to the values of their ancestors.
