As the Norfolk Roadster and Arab-bred horses gained popularity later on, they, too, were selected to stand at the royal stud.

The breeding of Frederiksborgers continued with private breeders, though the needs of the people reshaped the horse to some degree.

In 1939, efforts to re-establish the breed were started, adding East Friesian, Oldenburgs, Thoroughbreds, and Arabians later.

The modern Danish Warmblood often traces back to the Frederiksborger through the female lines, though the pedigrees of these horses are mostly German.

So too do the Holsteiner Manfreid (Markgraf), Swedish Rousseau (Herzog), and the Hanoverians Atlantic (Abglanz), Ergo (Abendjaeger), and Boheme (Bolero).

In conformation and type, the Frederiksborger was "ahead of its time", so the horses express great quality and are quite uniform.

The greatest concern facing the health of the Frederiksborger is inbreeding due to a limited gene pool.
