Treaty of Westphalia

1648 peace accords

The Treaty of Westphalia (1648) ended the Thirty Years' War in Europe, establishing principles of state sovereignty and non-interference that shaped modern international relations.

The treaties recognized that rulers could determine their territories' religion, effectively ending the era of religious wars.

Westphalian sovereignty now refers to the principle that nation-states have exclusive authority within their borders.
