Treaty of Constance

The Treaty of Constance, signed in 1183, was an agreement that aimed to resolve conflicts between the Holy Roman Empire and the northern Italian city-states, particularly concerning their autonomy and political rights. This treaty recognized the cities' self-governance, allowing them a degree of independence while still acknowledging the Emperor’s authority. It helped stabilize relations and reduce military conflicts in the region, setting a precedent for future agreements regarding local governance and imperial authority in Italy. Ultimately, it contributed to the evolution of municipal rights and the political landscape of medieval Italy.
