American-Quarter-Horse history
The American Quarter Horse is the first breed of horse native to the United States. The breed evolved when the bloodlines of horses brought to the New World were mixed. Foundation American Quarter Horse stock originated from Arab, Turk and Barb breeds. Selected stallions and mares were crossed with horses brought to Colonial America from England and Ireland in the early 1600s. This combination resulted in a compact, heavily muscled horse that evolved to fill the colonist's passion for short-distance racing.
