# Peace of Westphalia Signed

> This treaty ended the Thirty Years' War, established the nation-state system as Europe's governing principle, and secularized international relations.

Two peace treaties signed in Osnabrück and Münster in October 1648 ended the Thirty Years' War, a brutal conflict that had devastated Central Europe since 1618. The agreements created the modern system of sovereign nation-states and established principles of international law that still govern relations between countries today.

## Summary

The Peace of Westphalia is the collective name for two peace treaties signed in October 1648 in the Westphalian cities of Osnabrück and Münster. They ended the Thirty Years' War (1618–1648) and brought peace to the Holy Roman Empire, closing a calamitous period of European history that killed approximately eight million people. Ferdinand III, Holy Roman Emperor, the kingdoms of France and Sweden, and their respective allies among the princes of the Holy Roman Empire, participated in the treaties.

## Impact

Westphalia rewrote the rules of European politics by establishing sovereign statehood as the organizing principle of international order. The treaties killed the notion of universal Catholic empire, fragmented the Holy Roman Empire into semi-autonomous territories, and introduced the legal concept that nation-states answer to no higher authority—a foundation for modern international relations.
