Equestrianism (from Latin , , , 'horseman', 'horse'), commonly known as horse riding (Commonwealth English) or horseback riding (American English), includes the disciplines of riding, driving, and vaulting. This broad description includes the use of horses for practical working purposes, transportation, recreational activities, artistic or cultural exercises, and competitive sport. Overview of equestrian activities Horses are trained and ridden for practical working purposes, such as in police work or for controlling herd animals on a ranch. They are also used in competitive sports including dressage, endurance riding, eventing, reining, show jumping, tent pegging, vaulting, polo, horse racing, driving, and rodeo (see additional equestrian sports listed later in this article for more examples). Some popular forms of competition are grouped together at horse shows where horses perform in a wide variety of disciplines. Horses (and other equids such as mules) are used for non-competitive recreational riding, such as fox hunting, trail riding, or hacking. There is public access to horse trails in almost every part of the world; many parks, ranches, and public stables offer both guided and independent riding. Horses are also used for therapeutic purposes both in specialized para-equestrian competition as well as non-competitive riding to improve human health and emotional development. Horses are also driven in harness racing, at horse shows, and in other types of exhibition such as historical reenactment or ceremony, often pulling carriages. In some parts of the world, they are still used for practical purposes such as farming. Horses continue to be used in public service, in traditional ceremonies (parades, funerals), police and volunteer mounted patrols and for mounted search and rescue. Riding halls enable training of horse and rider in all weathers as well as indoor competition riding. History of horse use Though there is controversy over the exact date horses were domesticated and when they were first ridden, the best estimate is that horses first were ridden approximately 3500 BC. There is some evidence that about 3,000 BC, near the Dnieper River and the Don River, people were using bits on horses, as a stallion that was buried there shows teeth wear consistent with using a bit. However, the most unequivocal early archaeological evidence of equines put to working use was of horses being driven. Chariot burials about 2500 BC present the most direct hard evidence of horses used as working animals. In ancient times chariot warfare was followed by the use
