Which treaty ended the Thirty Years' War and affirmed that each prince could determine the religion of their state?

• A. Treaty of Westphalia
• B. Peace of Augsburg
• C. Edict of Nantes
• D. Treaty of Paris

Answer: (A)

The treaty that ended the Thirty Years’ War and established the principle that a ruler could determine the religion of his territory is the Treaty of Westphalia. This agreement in 1648 brought the long conflict to a close and enshrined the idea that princes within the Holy Roman Empire, and more broadly sovereign rulers, held the authority over the official religion of their lands. It also expanded religious tolerance beyond just Catholicism and Lutheranism to include Calvinism, and it reinforced the emerging system of state sovereignty. To place it in context, earlier, the Peace of Augsburg (1555) allowed rulers to choose either Catholicism or Lutheranism for their realms, but it didn’t resolve ongoing tensions and didn’t cover other denominations. The Edict of Nantes dealt with religious rights in France, not the German lands. The Treaty of Paris refers to various unrelated peace agreements. So, the Westphalia settlement uniquely ends the war and codifies the ruler-determines-religion idea.
