The Thoroughbred was developed purely for racing, for the enjoyment of the British royalty, aristocracy, and
gentry. The sport spread and is now one of the most popular in the world. Like its ancestor the Arab, the Thoroughbred has been used to improve many breeds, not only riding breeds, but also high quality carriage horses. Its use today goes much farther than racing for which, however, it is still principally bred.Thoroughbred horses stand about 16 to 17 hands high.
