The thoroughbred is around 300 years old, originally
bred and developed in England during the 16th and
17th century. By importing eastern stock such as Arabs, Barbs and Turkoman horses, and also the Spanish horses, with the racing sock already established they were able to improve the speed and
agilty of the new racehorse and thus improve and create the thoroughbred.
The breed has spread to all corners of the world, the American TB is almost as old as the English. Where
the 2000 Guineas of 1834 winner Glencoe was sent
to the USA and became very successful as a sire.

  All TB sire-lines trace back to one of three Arab
stallions, some would argue that one was a Barb and the other a Turkoman stallion. They were the
Darley Arabian, the Godolpin Barb (Arab) and the Byerly Turk (Arab). Horses often changed names as often as they changed hands. But many pedigrees trace back to
the
Curwen Bay Barb, who was a Barb, infact he appears in more early pedigrees than any other Eastern stallion.
