The Hackney Pony was originally developed by Christopher Wilson. He used Sir George, a Hackney stallion foaled in 1866, to breed with Fell Pony mares, and then interbred the offspring to make a fixed type of pony. He desired to create not a miniaturized horse, but rather a true pony with such characteristics. Extracting the large trot and other characteristics of the hackney horse and applying them to this true type of pony, he was successful in creating the form which was desired. This is one case of an entire type of breed that is formed in a controlled, private environment. In addition to the mixing of Fell ponies and Hackney horses, the Hackney Pony probably also has much Welsh Pony blood.
