The Lipizzaner, also known as the Lipizzan, was and is still bred in Lipizza (Lipica), now in Yugoslavia. This breed was founded around 1580 at which time 24 mares were imported from the Iberian Peninsula by the command of Archduke Charles II and crossbred with nine Spanish Stallions. The Lipizzaner was bred all over what used to be the Austro-Hungarian Empire. The Kladruber, a carriage horse, which was the base of the Spanish Stock in 1572 in Czechoslavakia had a great influence in the improvement of the Lipizzaner. These beautiful horses are associated with the Spanish riding school in Vienna, which was established in 1572. The riding school was used to instruct noblemen in classical horsemanship in an arena next to the Imperial Palace. The current school, the Winter Riding Hall, was completed in 1735 by orders of Charles VI. The horses for the school are raised at Austria's Piber Stud near Graz. There are other Lipizzaner breeding programs in Hungary, Romania, and Czechoslovakia. In these places there are slight variations of this breed, such as in Hungary the horses are bred bigger and greater array of movement.
