Modern Texas, like Mexico, traces its beginning to sixteenth-century encounters between Europeans and Indians who contested control over a vast land. Unlike Mexico, however, Texas eventually received the stamp of Anglo-American culture, so that Spanish contributions to present-day Texas tend to be obscured or even unknown. The first edition of Spanish Texas, 1519–1821 (1992) sought to emphasize the significance of the Spanish period in Texas history. Beginning with information on the land and its inhabitants before the arrival of Europeans, the original volume covered major people and events from early exploration to the end of the colonial era.

This new edition of Spanish Texas has been extensively revised and expanded to include a wealth of discoveries about Texas history since 1990. The opening chapter on Texas Indians reveals their high degree of independence from European influence and extended control over their own lives. Other chapters incorporate new information on La Salle's Garcitas Creek colony and French influences in Texas, the destruction of the San Sabá mission and the Spanish punitive expedition to the Red River in the late 1750s, and eighteenth-century Bourbon reforms in the Americas. Drawing on their own and others' research, the authors also provide more inclusive coverage of the role of women of various ethnicities in Spanish Texas and of the legal rights of women on the Texas frontier, demonstrating that whether European or Indian, elite or commoner, slave owner or slave, women enjoyed legal protections not heretofore fully appreciated.
