Bolero (1975 - 1986) was a dressage horse and an influential sire. He stood .
Bolero was by the English Thoroughbred stallion Black Sky, who was imported to Germany in 1972. Black Sky was a grandson of the great stallion Djebel, who also sired the very influential My Babu, a stallion seen in many show jumpers, and hunters pedigrees in the United States. Black Sky stood at the private stud farm of Schmidt-Ankum, and his offspring were generally talented dressage horses with good rideability, but with very little jumping talent. As such, Bolero is a male-line descendant of the Byerley Turk.
Bolero's dam, Baroness, was registered with the Hanoverian Verband. She was half-Thoroughbred through her sire, the large-framed stallion Bleep. Her dam's side includes Hyperion, who in turn traces to Bay Ronald. The dam-sire of Baroness was the stallion Athos, who was known as a broodmare sire of dressage horses, and her damline (Athos-Fliegerstern) also produced the stallions Grenadier, Hitchcock, and Winner.
This breeding combination of a Thoroughbred stallion to a mare that was by a Thoroughbred was prohibited by the Hanoverian studbook at the time, due to the belief that the offspring would be unsuccessful.
Pedigree for BoleroBolero did only moderately well at his 100-day stallion test held at Adelheidsdorf, placing 6th out of 30 stallions with a final score of 111. He stood at Landesbrück from 1979 until his death of a heart attack at the age of 12. He only stood for 9 seasons, making his impact on the breeding of Hanoverians even more spectacular.
Despite the relatively short breeding career, Bolero was remarkably influential on the breeding of dressage horses, although like his father, his offspring are generally poor jumpers. His high degree of Thoroughbred blood brought an elegance to his progeny, and this trend toward a lighter dressage horse has been on the rise since he stood at stud. He consistently produced offspring with good shoulders and toplines, as well as elastic and rhythmic gaits.
Bolero was the founding sire of a new B-Line in the 1990s, and produced the stallion Brentano II, who also became a foundation stallion for this line. Bolero was found to be most successful with daughters of Grande and Duellant. Breeders continue to cross the B-Line with the G- and D- lines to produce successful dressage horses, as well as those by Argus.
The stallion sired 47 licensed stallions during his time at stud, the most important being Brentano I and II, Buenos Aires, Bismark, and Beltain. As a well-known sire of sires, Bolero sons have been exported around the world. Bolero has also made a name for himself as a sire of broodmares, producing 317 mares that went on to be registered, 96 of whom earned the status of State Premium. The great success of his mares gave him a dressage ranking of 139 (against a rather poor 57 for jumping).
Bolero began with 5 sons attending the Verden licensing, of which 4 were selected. His offspring, known as the "Bolero Boom", continue to make their mark on the dressage scene. As of 2000, there were 412 Bolero offspring competing, with winnings of DM1,282,504. Three of his descendants medaled at the 2004 Summer Olympics in Athens, Greece: Brentina, Bonaparte, and Beauvalais.
