The Native American on a horse is an archetypal Hollywood image

but though such equestrian-focused societies were a relatively short-lived consequence of European expansion overseas, they were not restricted to North America's Plains. Horse Nations provides the first wide-ranging and up-to-date synthesis of the impact of the horse on the Indigenous societies of North and South America, southern Africa, and Australasia following its introduction as a result of European contact post-1492.

Drawing on sources in a variety of languages and on the evidence of archaeology, anthropology, and history, the volume outlines the transformations that the acquisition of the horse wrought on a diverse range of groups within these four continents. It explores key topics such as changes in subsistence, technology, and belief systems, the horse's role in facilitating the emergence of more hierarchical social formations, and the interplay between ecology, climate, and human action in adopting the horse, as well as considering how far equestrian lifestyles were ultimately unsustainable.
