Uri, Schwyz, and Unterwalden concluded the Federal Charter (Bundesbrief), a mutual-aid alliance often treated as a foundational constitutional text for the early confederation and its republican-leaning cooperative order among cantons.
Forces from Schwyz (supported by Uri and Unterwalden) defeated a Habsburg army near Morgarten. The victory strengthened the alliance system around the forest cantons and helped consolidate the confederation’s military credibility.
Uri, Schwyz, and Unterwalden renewed their mutual-defense commitment in the Pact of Brunnen, helping shift earlier cooperation toward a more durable sworn confederation.
The cantons concluded the Covenant of Sempach to standardize military conduct and coordination among confederates, reflecting the confederation’s increasing need for common rules despite strong cantonal autonomy.
At a crisis meeting in Stans, the Tagsatzung reached the Stanser Verkommnis compromise (traditionally associated with counsel from Niklaus von Flüe). It eased tensions between urban and rural cantons and enabled further expansion.
The Treaty of Basel (1499) concluded the Swabian War between the Swabian League and the Swiss Confederacy. It is widely associated with the confederation’s strengthened de facto autonomy within the Holy Roman Empire.
Appenzell became a full member of the Swiss Confederacy, completing the classic composition of the Thirteen Cantons and reinforcing the confederation’s federative republican character of self-governing cantons.

France and the Swiss Confederacy signed the Treaty of Fribourg (Perpetual Peace), shaping long-term diplomatic relations and often linked in scholarship and public memory to the development of Swiss neutrality.
The First Kappel War ended with an armistice and settlement at Kappel, temporarily preventing escalation between Catholic and Protestant cantons and demonstrating the limits of confederate cohesion during the Reformation.
In the Second Kappel War, Catholic cantons defeated Zürich at the Battle of Kappel; reformer Huldrych Zwingli was killed. The ensuing peace entrenched confessional boundaries within the confederation.
The Peace of Westphalia settlement formally confirmed the Swiss Confederacy as an independent republic, recognizing a sovereignty that had long existed in practice and further defining its position outside effective imperial control.
A major rural revolt (January–June 1653) erupted across several cantons, driven by fiscal and economic grievances. Although suppressed, it exposed tensions in the confederation’s republican order between city councils and subject rural communities.
French forces occupied Bern during the 1798 invasion, effectively ending the old confederation’s ancien-régime structures and its 13-canton order as revolutionary change spread.
Cantonal deputies proclaimed the Helvetic Republic, replacing the loose confederation with a centralized state under French influence—marking the end point of the Old Swiss Confederacy as a republican cantonal federation (1291–1798).
