* * *▪ breed of horsebreed of horse developed in England for racing and jumping (see photograph—>). The origin of the Thoroughbred may be traced back to records indicating that a stock of Arab and Barb horses was introduced into England as early as the 3rd century. Natural conditions favoured development of the original stock, and selective breeding was encouraged by those interested in racing. Under the reigns of James I and Charles I, 43 mares—the so-called Royal Mares—were imported into England, and a record, the General Stud Book, was begun in which were listed only those horses that may be traced back to the Royal Mares in direct line, or to one of three other horses imported to England: the Byerly Turk (imported in 1689), the Darley Arabian (after 1700), and the Godolphin Barb (about 1730). The English Thoroughbred has since been introduced to most countries, where it is bred for racing or used to improve local breeds. A son of the Darley Arabian, Bulle Rock, was imported to Virginia in 1730. During the following 45 years, 186 Thoroughbreds imported from England became the foundation of Thoroughbred breeding in the United States.Thoroughbreds have delicate heads, slim bodies, broad chests, and short backs. Their short leg bones allow a long, easy stride. They are sensitive and high-spirited. Averaging 16 hands (64 inches, or 163 cm) high and weighing about 1,000 pounds (450 kg) at maturity, Thoroughbreds are usually bay, chestnut, brown, black, or gray. Outstanding for speed and stamina, they have been combined with and have improved several other breeds of horses. The term thoroughbred is sometimes incorrectly used to mean purebred, but Thoroughbreds are a specific breed, registered in the General Stud Book of the English Jockey Club, organized about 1750, or in the studbooks of similar clubs in other countries.A horse having only one Thoroughbred parent is called a Grade Thoroughbred in the United States and a half-bred in Great Britain. Grade Thoroughbreds may be used as hunters, polo ponies, stock horses, or riding horses, depending on their training.Selected breeds of light horsesSee the Table of Selected Breeds of Light Horses (Selected breeds of light horses) for further information.
