Texas was inhabited by prehistoric peoples, who were nomadic hunters, as early as 12,000 to 15,000 years ago. When Europeans first came to the region, in the 16th century, there were 30,000 to 40,000 Indians in Texas. Of the many tribes in the area, the Caddoans were the most numerous then, but during the next 300 years Comanches became predominant.
