historically, each of the southern states had a very distinct population: rhineland-palatinate was a center for the breeding of elegant anglo-arabian riding horses, baden-württemberg bred arabians and arab-influenced riding horses at the state stud of marbach, and bavaria was home to the ancient heavy warmblood rottaler. of late, these three regions have combined their breeding and marketing efforts, so the modern bavarian warmblood, württemberger, and zweibrücker are increasingly indistinguishable. similarly, the eastern states of berlin-brandenburg, saxony-anhalt, saxony, and thuringia have begun hosting a common stallion inspection. each of these states has had its own flavor of warmblood, though perhaps the brandenburger was best known.
