Researchers at Wageningen University in the Netherlands have shed new light on the inbreeding challenges faced by the majestic Friesian horse breed.1
With their striking black coats, flowing manes, and high-stepping gait, Friesians have captured the hearts of horse enthusiasts worldwide. But there’s so much more to these incredible animals than meets the eye.
1. Friesians Have Been Around for Centuries
Friesian horses are believed to have existed since 1000 B.C., making them one of the oldest equine breeds. Roman historian Tacitus noted the breed’s existence as early as 55-120 A.D., describing them as powerful and versatile horses.
2. They Nearly Faced Extinction Multiple Times
Despite their popularity in the 16th and 17th centuries, Friesians almost disappeared in the early 20th century. By 1913, only three Friesian stallions remained in their home province of Friesland. (ref)

Thankfully, the breed was revived during World War II when fuel shortages made horsepower necessary once again.
3. Friesians Influenced the Development of Other Breeds
As one of the oldest breeds, Friesians played a role in the development of several newer breeds. The Oldenburger, Shire horse, Fell pony, Dales pony, and even the Morgan horse are believed to have inherited some Friesian bloodlines.
4. They’re Hollywood Stars
Friesians have graced the silver screen in numerous films, including Ladyhawke (1985), The Mask of Zorro, Eragon, and 300. Their striking appearance and flashy movement make them popular choices for various entertainment industries.
5. Two Ways to Spell Their Name
In English, the breed name is often spelled “Frisian” to differentiate it from Holstein Friesian cattle. However, breed books and registries spell “Friesian” with an “e.”
6. Strict Registration Standards
To be registered as a true Friesian, a horse must have a solid black coat with no white markings larger than 1.3 inches below the eye line. They typically stand between 15 and 17 hands (60-68 inches) tall.
7. Unique Physical Characteristics
Friesians have a Baroque body type with powerful conformation and good bone structure. They are known for their long, arched necks, short ears, and low-set tails. Their limbs are short and strong, with feathering (long hair) on the lower legs.
8. Versatile Athletes
While often associated with dressage and carriage driving, Friesians are versatile enough to participate in all equestrian sports and disciplines. Their intelligence and willing temperament make them adaptable partners.
9. Breeding Challenges
Due to historical bottlenecks and closed studbooks, the Friesian population has a high degree of inbreeding. This has led to concerns about genetic disorders and reduced fertility. Studbooks are working to address these issues through strategic breeding programs.
10. Friesian Foal Facts
Only 47.9% of female Friesian foals eventually become mothers, while a mere 3.5% of male foals father at least one offspring in their lifetime. Of the male foals that become sires, only 17% are approved stallions, with the remaining 85% being foalbook stallions. (ref)
11. Stallion Contributions
From 1945 to 1974, the top 10 approved Friesian stallions produced approximately 80% of the annual foal population. As of 2022, the top 10 approved stallions account for 35% of the total foal population, mainly due to an increased number of approved stallions rather than a more balanced distribution of contributions.
12. Inbreeding Rates Improving
Over 20 years ago, the inbreeding increase in Friesian horses was around 1.5% per generation. Thanks to studbook efforts, such as introducing a mating quota and publishing individual kinship values, the current inbreeding rate has been reduced to approximately 0.5% per generation. (ref)
However, the fight against inbreeding is far from over, and researchers continue to explore new strategies to preserve the genetic health of this beloved breed.
