The Swiss Black-Brown Mountain Sheep originates from the ancient Swiss breeds Jura, Simmentaler, Saanen, Frutiger, Roux de Bagnes and Freiburger. Frutig sheep are already known from records of the 14th Century. Their coarse, mainly white wool was quite important for the home industry producing the famous Frutig cloth. In the beginning of the 19th Century Flemish Landrace sheep were crossed in and Spanish Black Merinos around 50 years later. Another ancestor, the Roux de Bagnes, was a small-framed, compact, easily satisfied and hardy hill breed. In 1941 the breed description Black-Brown Mountain sheep was created and the various breeds were made uniform. The mutual flock book for black and brown varieties dates from 1979. Today this breed is raised mainly in Switzerland ( Fribourg, Bern, Jura, Lucerne and Zurich).

In Austria the first flock of Swiss Black-Brown Mountain sheep was introduced under the name Jura sheep by the shepherds of Longo Maï, wandering 1977 all the way from the Bernish Jura to Carinthia.
