Combining archaeological, historical, ethnographic, and environmental data, Land of the Tejas represents a sweeping, interdisciplinary look at Texas during the late prehistoric and early historic periods. Through this revolutionary approach, John Wesley Arnn reconstructs Native identity and social structures among both mobile foragers and sedentary agriculturalists. Providing a new methodology for studying such populations, Arnn describes a complex, vast, exotic region marked by sociocultural and geographical complexity, tracing numerous distinct peoples over multiple centuries.

Drawing heavily on a detailed analysis of Toyah (a Late Prehistoric II material culture), as well as early European documentary records, an investigation of the regional environment, and comparisons of these data with similar regions around the world, Land of the Tejas examines a full scope of previously overlooked details. From the enigmatic Jumano Indian leader Juan Sabata to Spanish friar Casanas's 1691 account of the vast Native American Tejas alliance, Arnn's study shines new light on Texas's poorly understood past and debunks long-held misconceptions of prehistory and history while proposing a provocative new approach to the process by which we attempt to reconstruct the history of humanity.
