The first detailed archival study of the indigenous populations of the early historic period in the Lower Rio Grande Valley of Texas and Mexico. 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, Martín 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 indigenous people, their lifeways, and on the relations between the them and the colonial Spanish missions in the region. “The scholarship is nothing short of superb . . . Salinas has produced the definitive work on the area, which has been needed for years.” —Rudolph C. Troike, Professor, Department of English, University of Arizona
