The Thoroughbred is a breed of horse whose ancestry can be traced back to one of three foundation sires – the Darley Arabian, the Godolphin Arabian and the Byerly Turk.  The three were named for their owners – Thomas Darley, Lord Godolphin and Captain Robert Byerly – who brought the stallions from the Middle East to England in the 17th century where they were bred to the native horses.  The result was a horse that could carry weight at sustained speed over extended distances, qualities that brought a new dimension to the sport of horse racing.

Selective breeding of the best mares to the best stallions has continued for more than 300 years with the abilities of their offspring delineated on the racecourse.  Horseracing was introduced in the American colonies before the Revolutionary War and the first American Stud Book was published in 1873.

The Jockey Club, which maintains the American Stud Book, oversees the naming of all Thoroughbred foals in the United States.
