Growth of the Old Swiss Confederacy: The Schweizer Eidgenossenschaft ambushes the army of Leopold I in the Battle of Morgarten.

The Old Swiss Confederacy began as a late medieval alliance between the communities of the valleys in the Central Alps, at the time part of the Holy Roman Empire, to facilitate the management of common interests such as free trade and to ensure the peace along the important trade routes through the mountains. The Hohenstaufen emperors had granted these valleys reichsfrei status in the early 13th century. As reichsfrei regions, the cantons of Uri, Schwyz, and Unterwalden were under the direct authority of the emperor without any intermediate liege lords and thus were largely autonomous.
