The Spanish offered many wonderful things that Native Americans found useful or beautiful — iron for tools, weapons, glass beads, mass-produced pottery — but the most prized possession of many Indians was the horse.
Soon after they arrived in America, the Spanish reintroduced horses to the continent. The Spanish horses were from the finest strains and were regarded as the top breed in Europe. Plains Indians prized them. Stallions and mares that escaped from the Spanish started the great herds of wild horses that spread north from Mexico into the United States and the western Plains country. These herds of wild horses still exist.
Horses reached Nebraska by the 1680s and the upper Missouri by the 1750s. Tribes in eastern Nebraska (Pawnee, Ponca, Omaha, and Oto) used horses for buffalo hunts, but continued to grow maize and live in earth lodge villages. In the western part of the state, the Sioux, Cheyenne, and Arapaho lived in skin tepees and roamed over most of western Nebraska as nomadic hunters. Horses allowed them to expand their traditional nomadic lifestyle across the plains.
