The Friesian stud registry book, FrieschPaardenStamboek (FPS) was founded in 1879 by a group of Dutch farmers dedicated to preserving the breed.

Friesians had become popular for crossbreeding due to their fantastic trot, presence, and color, and as a result, Friesian “purity” was severely threatened. The “Royal Society Het FrieschPaarden-Stamboek” was founded to protect and promote the breed’s bloodline.

Friesian horse populations then dwindled in the early 20th century partly due to displacement by petroleum-powered farm equipment and passenger vehicles. Due to fuel rationing during World War II the Friesianโ€™s farm and carriage use was revived, saving the breed long enough for both its population and popularity to rebound.
