The Tori was developed between 1890 and 1950 in Estonia by crossbreeding native Estonian mares with European halfbred stallions. The stallion Hetman founded the breed. Hetman is the son of and unknown hunter mare and Stewart, a crossbreed of an Anglo-Norman mare and a Norfolk Trotter. Hetman and his sons were extensively used in the breed until signs of inbreeding manifested themselves in presentation and strength by the end of the 1930s. To eliminate the inbreeding depression, they crossbred Breton Post-horse stallions resulting in the decline in quality of the gaits and the horses massive size. The Tori horses were then experimentally crossed with Hanoverian and Trakehner stallions to make a horse with a combination of utility and sporting qualities. The Tori is an all-purpose utility breed that is clearly a harness type with a clean solid build. These horses have great performances in competitions of draft work. In recent years many breeders with the ideal of wanting an extremely light sporthorse-type have bred their horses with studs whose quality was not tested or suggested. This selection has resulted in less than 100 purebreds with only three purebred studs remaining in 1999.
