 At the World Championship a group of judges evaluate the horses in age and gender categories as well as in various sport disciplines and a halter class.The ancestors of the breed may date back to animals living 3,000 years ago, known by a number of names, but most often as the Nisean horse.The precise ancestry is difficult to trace, however, because prior to about 1600 AD, horse breeds in the modern sense did not exist; rather, horses were identified by local strain or type.
