The Hanoverian, a European warmblood, originated in Celle, Germany in the 17th century established by George II, King of England and Elector of Hanover. They wanted to create a basis of strong stallions to mate with local mares to create a great all-around farm horse. They based the breeding from black Holsteins and the local mares with bits of crossbreeding with oriental, Spanish, and Neapolitan blood. The Thoroughbred was also introduced to create a slightly lighter and better working horse in harness and as a cavalry mount. The Thoroughbred crossbreeding was carefully monitored to make sure that the outcome did not make the Hanoverian horse to light.The stallion population was 500 by 1924. The Hanoverian breeding process takes great emphasis into the temperament of each horse. They are bred for their calmness, agreeable temperament, and reliability. The policy was directed to the production of riding competition horses after the Second World War. The Hanoverian was then crossbreed with Trakehners and slightly more Thoroughbred influence. The Hanoverian is probably the most successful of European horses as it has a worldwide standing as dressage horse and show jumper.
