The Quarter Horse is a breed of horse known for its speed and agility, particularly in short-distance races. Originating in the United States, it was developed in the 17th century by crossing Thoroughbreds with local horses. Quarter Horses are typically muscular and compact, making them well-suited for various equestrian activities, including rodeo events and ranch work. These horses are named for their ability to outpace other breeds in quarter-mile races. They have a calm temperament, which makes them popular among riders of all skill levels. The breed is also recognized for its versatility, excelling in disciplines such as barrel racing and team roping.
