The Hanoverian is a Warmblood horse breed originating in Germany, which is often seen in the Olympic Games and other competitive English riding styles, and has won gold medals in all three equestrian Olympic competitions. It is one of the oldest, most numerous, and most successful of the Warmblood breeds. Originally a cavalry horse, infusions of more Thoroughbred blood lightened it to make it more agile and useful for competition. The Hanoverian is known for a good temperament, athleticism, beauty, and grace.
