The local mares were refined with Holsteiner, Thoroughbred and Cleveland Bay, Neapolitan, Andalusian, Prussian, and Mecklenburg stock.
In 1867, breeders started a society aimed at producing a coach and military horse, with the first stud book being published in 1888.
[2][3][4] Hanoverians are consistently rated high against other sport horse breeds in dressage, show jumping and eventing.
[10] In 2008, four Hanoverian sires were ranked in the top 10 show hunters: All the Gold (2), Rio Grande (4), Escudo I (5) and Espri (8).
The verband maintains the studbooks, issues passports, and collects and publishes performance statistics, while educating members about and encouraging research into all aspects of breeding and keeping healthy Hanoverians.
[13] The Association for the Promotion of Hanoverian horses in Equestrian Sport (Verein zur Förderung des Reitsports auf Hannoverschen Pferden) was founded in 1985 and operates under the verband.
[15][16] There are two Hanoverian breeding clubs in Canada, in addition to groups in the United Kingdom, Denmark, Finland, France, and Russia.
The verband is responsible for many events and facilities related to the Hanoverian horse, including selection procedures for breeding stock and the famous Elite Auctions in Verden.
[17] There are at least ten auctions per year, each featuring top-quality riding horses, promising foals, proven broodmares, or licensed stallions.
The most famous of these sales are the Elite Riding Horse Auctions held in April and October each year.
[17] Horses are delivered to the venue four weeks prior to the auction for training, promotion, and thorough screening for radiographic irregularities and vices.
The many steps and careful evaluations of Hanoverian breeding stock are organized by the verband and district breeders' clubs (bezirkverband).
[20] Each year, the seven regional clubs nominate a total of 700 two-year-old colts as stallion candidates, of which only 100 attend the actual licensing (koerung) at Verden in October.
[21] A panel of verband-selected judges, experts in their fields, form the koerkommission, which evaluates each young stallion for his suitability as a sire of future Hanoverians.
These four-week-long tests are a more in-depth evaluation of a mare's suitability for riding; in addition to her talents for dressage or show jumping, the judges can form an understanding of her character and temperament, including how easy she is to train.
These tests are held at the Hanoverian Riding and Driving School in Verden and at the Hessen State Stud in Dillenburg.
