Unterwalden in the context of "William Tell"

The early history of Switzerland begins with the earliest settlements up to the beginning of Habsburg rule, which in 1291 gave rise to the independence movement in the central cantons of Uri, Schwyz, and Unterwalden and the growth of the Old Swiss Confederacy during the Late Middle Ages.

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 (or regions) of Uri, Schwyz, and Unterwalden were under the direct authority of the emperor without any intermediate liege lords and thus were largely autonomous.

With the rise of the Habsburg dynasty, the kings and dukes of Habsburg sought to extend their influence over this region and to bring it under their rule; as a consequence, a conflict ensued between the Habsburgs and these mountain communities who tried to defend their privileged status as reichsfrei regions. The three founding cantons of the Schweizerische Eidgenossenschaft, as the confederacy was called, were joined in the early 14th century by the city states of Lucerne, Zürich, and Bern, and they managed to defeat Habsburg armies on several occasions. They also profited from the fact that the emperors of the Holy Roman Empire, for most of the 14th century, came from the House of Luxembourg and regarded them as potential useful allies against the rival Habsburgs.

The Sonderbund War (German: Sonderbundskrieg, French: Guerre du Sonderbund, Italian: Guerra del Sonderbund) of November 1847 was a civil war in Switzerland, then still a relatively loose confederacy of cantons. It ensued after seven Catholic cantons formed the Sonderbund ("separate alliance") in 1845 to protect their interests against a centralization of power. The war concluded with the defeat of the Sonderbund. It resulted in the emergence of Switzerland as a federal state, concluding the period of political "restoration and regeneration" in Switzerland.

The Sonderbund consisted of the cantons of Lucerne, Fribourg, Valais, Uri, Schwyz, Unterwalden and Zug, all predominantly Catholic and governed by conservative administrations. The cantons of Ticino and Solothurn, also predominantly Catholic but governed by liberal administrations, did not join the alliance.

Waldstätte (German: [ˈvaltʃtɛtə], "forested sites/settlements;" Latin: civitates silvestres) is a term which has been used since the early thirteenth century to refer to the Stätte (singular: Statt, "site" "settlement"), or later Ort(schaft) (plural: Orte, "locality" "place" "lieu") or Stand (plural: Stände, "estate") of the early confederate allies of Uri, Schwyz and Unterwalden in today's Central Switzerland.

From the 13th to 19th centuries, the term Waldstätte also synoptically referred to the nucleus of the Swiss Confederacy of Uri, Schwyz and Unterwalden; later, the term was gradually replaced by the term Urschweiz.

The Rütli Oath (German: Rütlischwur, Swiss Standard German pronunciation: [ˈryːtliˌʃvuːr]) is the legendary oath taken at the foundation of the Old Swiss Confederacy (traditionally dated to 1307) by the representatives of the three founding cantons, Uri, Schwyz and Unterwalden.It is named after the site of the oath taking, the Rütli, a meadow above Lake Uri near Seelisberg. Recorded in Swiss historiography from the 15th century, the oath is notably featured in the 19th century play William Tell (Wilhelm Tell) by Friedrich Schiller.
