The introduction of the horse to North America drastically changed the lives of many American Indians. Some tribes who had been historically sedentary started using horses and became nomadic due to the horses. Ranges were now expanded due to the horses, so tribes could hunt more, as well as more contact with other tribes increased competition and warfare. A person's wealth in a tribe could equally be measured by how many horses he owned and if he was able to catch a horse during a conflict.
