Hasíinay

The Hasíinay were a confederacy of Caddo-speaking peoples between the Sabine and Trinity rivers in eastern Texas. Their Caddoan ancestors built ceremonial earthwork mounds and cultivated maize before European contact.

In the seventeenth century, the Hasíinay traded with the Jumano at Nabedache. Epidemics devastated the confederacy: its population fell from around 10,000 in 1690 to about 2,000 by 1720.
