History of the Thoroughbred Horse Breed
The Thoroughbred horse breed has its beginnings in England during the late 1600s and early 1700s when Byerly Turk, the Godolphin Arabian, and the Darley Arabian were imported there and bred to mares that originated there. Specifically, they were bred to 43 royal mares owned by King James I and King Charles I.
The result of these crosses were horses that could carry substantial weight at high speeds over long distances, the characteristics needed for racing. This line of Thoroughbreds was the introduction of the English Thoroughbred.
Since these crosses were successful, breeders started a selective breeding program to create the best horses for the sport.
The American Thoroughbred we know today was created when Bulle Rock, a son of the Darley Arabian, was imported in 1730. From there, 186 more Thoroughbreds were imported to make its foundation.
The first Thoroughbred race in North America was held in 1745 in Annapolis, Maryland and the sport has gained worldwide popularity since then.
When horse racing became popular in North America in the 1800s, Kentucky and Tennessee became headquarters for Thoroughbred breeding and racing.
All Thoroughbreds have the genetics of the three foundation stallions, Eclipse, a great-great-grandson of the Darley Arabian, is credited with being the foundation stallion for 80% of modern Thoroughbred horses.
Thoroughbred Characteristics and Temperament
The Thoroughbred has several characteristics that distinguish it from other horse breeds. They are tall and elegant, but have incredible musculature and stamina. They have a long and lean face with a slight slope to it that comes from their Arabian ancestry. Their withers are high compared to average horses and they have a long back.
They also have a fine-haired coat and delicate skeletal structure, which contributes to their athletic ability and speed.
These features, as well as a large heart, enable them to run at high speeds for long distances. The heart supplies a greater oxygen supply to the body to support this. Their fine coat gives them a silky and shiny appearance.
Thoroughbreds are a breed with a lot of energy, but they love to work. They are easy to train and are extremely sensitive to rider cues.
Their excitable nature makes them best for riders with at least some experience handling horses, as they would know how to handle a sudden spook or bolt. They can succeed in disciplines such as hunting, jumping, eventing, and racing.
- Short, fine, and silky coat
- Muscular, yet refined and elegant body

Thoroughbred Breed Standard
The Jockey Club is the organization that establishes the breed standard and naming conventions for Thoroughbreds in the US. It took over the publishing of the American Studbook, a close copy of the General Studbook for English Thoroughbreds, from Col. Sanders D. Bruce in 1896.
Now, The Jockey Club uses a computer system to manage a database of more than 3 million Thoroughbreds in a master file that began in the late 1800s.
The breed standard of the Thoroughbred according to the Jockey Club is as follows:
- Refined head, with spaced out eyes
- Long and refined neck
- High and well-defined withers
