Darley Arabian


The Darley Arabian was one of three dominant foundation sires of modern Thoroughbred horse racing bloodstock, whose arrival in England during the reign of Queen Anne was the event which "forms the great epoch from which the history of the Turf should be dated". The other two founders were the Godolphin Arabian and the Byerley Turk. This bay Arabian horse was bought in Aleppo, Syria, by Thomas Darley in 1704 and shipped back to Aldby Park in England, as a present for his brother.
There he stood at stud, usually private but sometimes open to outside mares. He was the leading sire in Great Britain and Ireland in 1722. By all accounts, the Darley Arabian stood about 15 hands high and was of substantial beauty and refinement.
The Darley Arabian sired the undefeated Flying Childers. He also sired Bartlett's Childers, an unraced brother of Flying Childers, who was the great-grandsire of the extremely influential Eclipse. The Darley Arabian was to become the most important sire in the history of the English Thoroughbred. His son Bulle Rock was the first Thoroughbred to be exported to America, in 1730.
Most Thoroughbreds can be traced back to Darley Arabian. In 95% of modern Thoroughbred racehorses, the Y chromosome can be traced back to this single stallion.
