The treaty that ended the Thirty Years' War and established the principle of state sovereignty in Europe.
The Peace of Westphalia, signed in 1648, marked the end of the Thirty Years' War, a devastating conflict that ravaged Europe. This series of treaties, concluded in the cities of Münster and Osnabrück, involved major European powers such as the Holy Roman Empire, France, Sweden, Spain, and the Dutch Republic. The treaty is historically significant for establishing the concept of state sovereignty, which laid the groundwork for the modern international system of nation-states. By recognizing the autonomy of states and enshrining the principle of non-interference in domestic affairs, the Peace of Westphalia fundamentally altered the political landscape of Europe. It also redrew borders, recognized the independence of the Dutch Republic, and addressed religious conflicts within the Holy Roman Empire, setting a precedent for future diplomatic negotiations.
