Certain to become a standard reference in its field, Indians of the Rio Grande Delta is the first single-volume source on these little-known peoples. Working from innumerable primary documents in various Texan and Mexican archives, author Martin Salinas has compiled data on more than six dozen named groups that inhabited the area in the sixteenth through the eighteenth centuries. Depending on available information, he reconstructs something of their history, geographical range and migrations, demography, language, and culture. He also offers general information on various unnamed groups of Indians, on the lifeways of the indigenous peoples, and on the relations between the Indian groups and the colonial Spanish missions in the region.
