History of the American Quarter Horse
The American Quarter Horse developed in the colonial United States during the 1600s, when English horses were crossed with Spanish stock brought by settlers. The result excelled at sprinting quarter-mile races, earning the breed its name. As pioneers pushed west, its agility and cow sense made it the definitive ranch and cattle horse. The American Quarter Horse Association, founded in 1940, is now the largest breed registry in the world.
