Thoroughbred racing was one of the first major sports in early America. Horse racing thrived because it was a high-status sport that attracted the interest of both old and new money. It grew because spectators enjoyed the pageantry, the exciting races, and, most of all, the gambling.

As the sport became a national industry, the New York metropolitan area, along with the resort towns of Saratoga Springs (New York) and Long Branch (New Jersey), remained at the center of horse racing with the most outstanding race courses, the largest purses, and the finest thoroughbreds.

The sport's survival depended upon the racetrack being the nexus between politicians and organized crime. The powerful alliance between urban machine politics and track owners enabled racing in New York to flourish. Racetracks became a key connection between the underworld and Tammany Hall, enabling illegal poolrooms and off-course bookies to operate. Organized crime worked in close cooperation with machine politicians and local police officers to protect these illegal operations. In The Sport of Kings and the Kings of Crime, Riess fills a long-neglected gap in sports history, offering a richly detailed and fascinating chronicle of thoroughbred racing's heyday.

"This impressive work deserves the attention of scholars even if they care little about sports per se." (The Journal of American History)

"This work will stand as a source-of-record for historians for years to come." (Saratoga Living)

"Riess has broken new ground with his richly-textured study of the dynamic relationship between horse racing, politics, and gambling as they built New York's thoroughbred industry a century ago." (Field Horne, author of The Saratoga Reader)
