The Battle of Dornach was a battle fought on 22 July 1499 between the troops of Emperor Maximilian I and the Old Swiss Confederacy close to the Swiss village of Dornach. The battle turned into a decisive defeat for Maximilian, and concluded the Swabian War between the Swiss and the Swabian League: it amounted to de facto independence of Switzerland from the Holy Roman Empire, acknowledged by Maximilian in the Treaty of Basel on 22 September (the independence was however not formally recognized until the Peace of Westphalia of 1648).
