In short
In 1648, negotiators from across Europe gathered in the German towns of Münster and Osnabrück to end the Thirty Years' War, a religious and political conflict that had devastated the continent. The resulting Peace of Westphalia established a new model for international relations based on sovereign nation-states rather than religious or imperial authority, fundamentally reshaping the political map of Europe.

Impact
What followed.
Westphalia marked the end of the Thirty Years' War and introduced the concept of sovereign nation-states as the organizing principle for international politics. The settlement weakened the Holy Roman Empire and the papacy's political influence while strengthening France and Sweden, a power shift that defined European geopolitics for centuries. It established precedents for diplomatic negotiation and territorial settlement that became the foundation of modern international law.
