The Battle of Sörenberg was fought in 1380, between the Entlebuch (at the time subject to the House of Habsburg) and Obwalden (a canton of the early Swiss Confederacy). It was the culmination of a conflict over the right to alpine pastures (alps). The immediate cause was a cattle raid at an alp now known as Schlachtalp, at the slope of the Brienzer Rothorn, above the village Sörenberg.
