More than 100 year ago the number of privately owned stallions in the Hanoverian breed exceeded the number of state owned stallions, but then decreased again. In the past years the number of privately owned stallions increased constantly. Meanwhile private stallion owners all over the world offer about 390 stallions.

Some of these stallion owners founded the Verein hannoverscher Privathengsthalter e.V. (Club of Private Hanoverian Stallion Owners) in 1989. Their abbreviation, "P.B." has become a well-known "trademark" and they offer interesting sires, many of them have made a name for themselves in sports.

Every year in the beginning of February the great show of privately owned Hanoverian stallions is held in the Niedersachsenhalle at Verden.
