Peace of Westphalia Overview

The Peace of Westphalia, signed in 1648, marked the end of the Thirty Years’ War, a devastating conflict that had ravaged Central Europe. The peace treaties, negotiated in the cities of Münster and Osnabrück, established a new framework for European diplomacy and international relations.

The Peace of Westphalia is considered a landmark event because it introduced several key principles that have since become fundamental to modern international law and diplomacy. These principles included the recognition of the sovereignty of nation-states, the principle of non-interference in the domestic affairs of other states, and the concept of religious tolerance.
