The Dutch Warmblood is registered through the Koninklijk Warmbloed Paardenstamboek Nederland, commonly known by its Dutch acronym KWPN. This translates to the Royal Warmblood Studbook of the Netherlands, with the "Royal" designation granted by the Dutch monarchy in recognition of the organization's significance to Dutch culture and economy. Internationally, horses are typically referred to as Dutch Warmbloods or simply KWPN horses.
The KWPN organization maintains one of the world's most influential sport horse registries, with strict selection criteria that have produced consistent international success. The studbook encompasses several breeding directions including riding horses, harness horses, and Gelders horses, though the riding horse type achieves the greatest international recognition. Registration involves rigorous inspection and performance testing protocols.
Like all domestic horses, the Dutch Warmblood carries the scientific classification Equus ferus caballus. Within the warmblood category, KWPN horses represent a population rather than a pure breed in the traditional sense, with the studbook remaining open to approved outside bloodlines that can improve the population. This approach allows continuous genetic improvement while maintaining type consistency.
The term "warmblood" itself indicates the breed's heritage combining "hot blood" from Thoroughbred and Arabian influences with "cold blood" from heavier European horses. Dutch Warmbloods share this warmblood designation with German, Belgian, Danish, Swedish, and other European sport horse populations, with significant genetic exchange occurring between studbooks while each maintains distinct selection criteria and breeding goals.
