At the beginning of the 1900's large numbers of Hackneys were still being exported all over the world. Hackney classes at the large horse shows were extremely popular and Hackneys were also playing their part in the First World War as cavalry mounts and artillery horses. The time between the war years saw a large growth in the professionally trained show Hackney as opposed to the privately produced animal but with the advent of the Second World War and the invention of the motor car, Hackneys breeding was deemed non essential. After the war the emphasis on breeding shifted to producing the show animal, we know today. This spectacular show harness animal, with his presence, athleticism, elegance, stamina and soundness is a product of many centuries of careful breeding. Their value as a cross to produce show jumpers and today's sports horse is very well recognised, and they continue to have remarkable success in all forms of driving competitions.
