Providing healing support for everyone from an autistic child to a wounded veteran is just the latest addition to the horse's 5,000-year-old résumé. No animal has played a greater role in human history. Horses have carried us into war, pulled our loads, plowed our fields, and transported us over all kinds of terrain. Freed of such drudgery by motorized devices, horses now provide companionship and entertainment. This feature article traces the history of horses in North America, highlights American horse breeds, and describes the many ways Americans interact with horses including trail rides, horse shows, and equine therapy. The traditions of the Triple Crown of Thoroughbred Racing (Kentucky Derby, Preakness Stakes, and Belmont Stakes) and the role of horses in popular culture are also discussed.
