Battle of Hausbergen

The Battle of Hausbergen was a historic military engagement that took place in the Alsace region of northeastern France on the 8th of March 1262. The battle marked the release of the 'burghers' of Strasbourg from episcopal authority and gave the bourgeoisie control over politics and commerce. The battle occurred on the fields of Hausbergen, an area of countryside a few miles northwest of the city of Strasbourg. It resulted in the decisive victory of the townsmen over the forces of the Bishop of Strasbourg, Walter of Geroldseck and the granting of free imperial city status by King Philip of Swabia to Strasbourg.
