Horse racing in the United States dates back to 1665, which saw the establishment of the Newmarket course in Salisbury, New York, a section of what is now known as the Hempstead Plains of Long Island, New York.[1] This first racing meet in North America was supervised by New York's colonial governor, Richard Nicolls. The area is now occupied by the present Nassau County, New York, region of Greater Westbury and East Garden City.
Horse racing remains a popular sport throughout the United States.
