The Hackney horse is a recognized breed of horse that was developed in Great Britain. A stud book has been maintained for this breed since 1883 by the Hackney Horse Society, which has its headquarters in Norwich, England. In recent decades, the breeding of the Hackney has been directed toward producing horses that are ideal for carriage driving. They are known for their great stamina, trotting at high speed for extended periods of time. In addition to inherent soundness and endurance, the Hackney Horse has proven to be a breed with an easy, rhythmic canter, and a free, generous walk.
