What treaty ended the Thirty Years' War?

The Peace of Westphalia, which concluded the Thirty Years' War in 1648, is significant for several reasons. This treaty marked a turning point in European history by establishing the principle of state sovereignty, which recognized the right of self-determination for nations and laid the groundwork for the modern international order. The agreements reached in the Peace of Westphalia, which involved multiple treaties, effectively ended both the Thirty Years' War in the Holy Roman Empire and the Eighty Years' War between Spain and the Dutch Republic.

The successful resolution of these conflicts through the Peace of Westphalia was a landmark moment, as it highlighted the importance of diplomacy and negotiation in international relations, rather than solely the resolution of disputes through warfare. Additionally, it allowed for a degree of religious toleration within the territories involved, ultimately contributing to the weakening of the religious uniformity that had characterized much of Europe during the Reformation and its aftermath.

In contrast, the Treaty of Versailles, signed in 1919, ended World War I, while the Treaty of Utrecht in 1713 resolved the War of the Spanish Succession. The Treaty of Fontainebleau, which occurred in 1685, focused primarily on the revocation of the Edict of Nantes
