American Warmblood: The Ultimate Horse Breed Profile

The American Warmblood stands as a testament to equine excellence, specifically bred for competing in esteemed equestrian disciplines including dressage, show jumping, eventing, and combined driving.

Integral to its identity and registration criteria, these horses must originate from the United States, Canada, or Mexico, marking their unique stature in the global arena of sport horses. This breed encapsulates the essence of North American equestrian tradition and innovation.


The history of American Warmblood horses is an impressive tapestry of development and breeding that spans nearly 200 years, featuring significant importations events that helped transform it into a versatile sport horse with wide appeal. You can trace its evolution by exploring several key phases or contributions;

Early Beginnings (1730s-18th Century):

Bulle Rock (1730): Our story begins with the arrival of Bulle Rock, an English Thoroughbred horse, to America in 1730. Matings between him and 39 distinct mares established a foundation for genetic diversity among American equine breeding programs.

Post-Revolutionary War Imports: The importation of Messenger in 1788 and Diomed in 1798 – both influential English Thoroughbreds – marked an important turning point. While Messenger helped shape Standardbred breeding, Sir Archy from Diomed’s progeny made an indelible impactful mark on American Thoroughbred breeding.

Developments from the 19th Century:

Thoroughbred Dominance: Thoroughbreds rose to prominence during the 19th century as they quickly became one of the most widely popular breeds in America, helping refine many American and imported strains.

Civil War Era Thoroughbred horses were the preferred mounts of choice for U.S. Cavalry during the Civil War, with half-bred horses becoming particularly prized; notable mounts like Robert E. Lee’s Traveller serve as proof of their effectiveness.

Early 20th Century and World Wars:

U.S. Army Remount Service (Early 1900s): Recognizing the value of “half-bred horses” as cavalry mounts, the U.S. Army Remount Service set out to develop the ideal cavalry horse through collaboration between professional breeders and the Bureau of Animal Industry.

Shift to World War II (1940s): By WWII, attention shifted from combat to breeding horses for equestrian sports breeding. Remount Service continued its operations as usual but began emphasizing mule production due to changing military needs.

Post-War Developments and International Influences:

European Influence (1950s-1960s): The advent of France’s Selle Francais competitions and German warmbloods’ popularity were major influences in shaping American breeding strategies. German Oldenburg breeders’ integration of various warmbloods with Thoroughbreds became the basis of many American breeding approaches.

Establishment of American Warmblood Registries (1980s): In the 1980s, two organizations known as the American Warmblood Registry and Society were created to formalize the concept of an American-bred sport horse. Their focus lies on quality and performance – in line with U.S. Cavalry’s original vision.

Modern American Warmblood (Late 20th Century to Present)

Diverse Genetic Influences: Today’s American Warmblood breed draws on influences from European warmbloods, Thoroughbreds, Arabians, Anglo-Arabians and draft breeds like Belgian Draught and Percheron horses.

Registry and Breeding Practices: Both the American Warmblood Society and Registry emphasize performance over lineage with an “open book policy,” encouraging an assortment of bloodlines to add diversity to this breed’s quality and versatility.

Expansion into Pony Breeding

Sport Pony Books: To expand their performance-focused approach to ponies, both registries have also established sport pony books in North American pony breeds, creating a similar culture across breeds.

Overall, the American Warmblood’s history can be described as one of strategic breeding, informed by global equine trends and tailored to America’s equestrian needs and visions.

From early colonial origins through to its current position as an elite sport horse breed, its rich legacy encompasses centuries of selective breeding and adaptation – which all can be witnessed today in its modern forms.


The American Warmblood is known for its versatility and athletic prowess. As part of this breed’s unique makeup are specific physical attributes, registration criteria, and performance standards that set it apart as one of the premier breeds for equestrian sports competition. These features can generally be divided into physical attributes, registration criteria, and performance standards:

Physical Attributes:

Size: American Warmbloods typically range between 15-17 hands high (60 to 68 inches, or 173 cm), giving them agility and strength across various disciplines.

Color: These horses may exhibit any color imaginable, with solid hues being most often observed. Their unique hues contribute to their visual appeal in the show ring.

Registration Criteria:

Bloodline Diversity: Its Registration is inclusive, welcoming horses of nearly all bloodlines as long as they embody either sport horse or warmblood types.

Focus on Quality: Registration and breeding approval decisions should center around each horse’s quality rather than breed classification restrictions for American Warmbloods. While ideal candidates typically feature warmblood type features, no specific breed regulations exist to limit American Warmblood registrations.

Diverse Breeds Welcomed: Draft horses, Arabians and Thoroughbreds that exhibit hot or cold blood temperatures such as draft horses are eligible for registration if they meet performance standards set forth by their registry.

Gaited Breeds: Gaited horse breeds such as Tennessee Walkers, Missouri Fox Trotters or Icelandics may not fit the traditional definition. But if they can demonstrate the ability to walk-trot-canter within accepted disciplines they too may be registered.

Performance Standards and Breeding Approval

Performance Criteria: Horses that initially do not or have yet to meet performance criteria may still receive recording papers but are not registered American Warmbloods until they meet either the performance or inspection standards required for registration.

Breeding Stock Inspection: In order to gain breeding approval, both mares and stallions undergo an in-depth studbook inspection process that adheres to more stringent inspection and/or performance criteria, guaranteeing only top specimens contribute to their breed’s history.

American Warmblood horses represent an intriguing blend of physical grace, genetic heritage diversity and stringent performance criteria that combine to distinguish this breed among various equestrian disciplines as well as demonstrate their dedication to upholding high standards of quality and versatility in equestrian sporting communities worldwide.

Performance and Temperament:

American Warmbloods are widely recognized for their versatility, excelling in multiple disciplines such as dressage, show jumping, eventing and driving.

One of their cherished attributes is their temperament – intelligent yet willing and eager to please, making them suitable for both professional riders and amateur riders. Furthermore, their trainability combined with physical capabilities make them excellent competitors in the equestrian world.
