The Peace of Basel, signed on September 22, 1499, concluded the Swabian War between the Swiss Confederation and the Holy Roman Empire, led by Emperor Maximilian I.1

This treaty effectively ended the Swiss Confederation's adherence to the imperial reforms and judicial decisions imposed by the Diet at Worms in 1495, such as the authority of the Reichskammergericht (Imperial Chamber of Justice). While the Swiss Confederation remained technically a subject of the empire, the peace settlement ensured there was little effective imperial control left over the Swiss territories.1

It is important to note that the formal exemption of Switzerland from the Holy Roman Empire was not achieved until the Peace of Westphalia in 1648, when the burgomaster of Basel, Johann Rudolf Wettstein, successfully secured the confederation's status as a sovereign republic.2
