Heavy warmblood

1898 lithograph depicting an Oldenburg horse, one type of heavy warmblood

The heavy warmbloods (German: Schwere Warmblüter) are a group of horse breeds primarily from continental Europe. The title includes the Ostfriesen ("East Friesian") and Alt-Oldenburger ("Old-Oldenburger"), Groningen, and similar horses from Silesia, Saxony-Thuringia, and Bavaria. Breeds like the Hungarian Nonius, Kladruber, and Cleveland Bay are also often classed as "heavy warmbloods." They are the ancestors of the modern warmbloods, and are typically bred by preservation groups to fit the pre-World War I model of the all-purpose utility horse. Unlike the registries of the sport horses that followed them, many heavy warmblood registries maintain closed or partly closed studbooks. However, external evaluation and performance testing of the breeding stock is still a key element in these registries. Many of the heavy warmbloods are selected primarily for family-friendly temperaments.
