The Thirty Years' War ended with which treaty?

• A. Treaty of Paris 1763
• B. Treaty of Westphalia
• C. Treaty of Tordesillas
• D. Treaty of Verdun

Answer: (B)

The end of the Thirty Years' War was achieved through a settlement that reshaped how Europe organized relations between states. The Peace of Westphalia, signed in 1648, brought the fighting to a close and established the idea that rulers have final authority within their own territories and that states should recognize each other’s sovereignty. This agreement also drew borders and laid the groundwork for a system of diplomacy where power is negotiated between independent states rather than resolved solely through religious or dynastic claims. That combination of ending the conflict and introducing a new order for international relations is why this treaty is the correct choice. The other treaties come from different times and contexts—one ending a much later global conflict, another dividing the lands of medieval Europe, and another an early medieval treaty—so they do not address the cessation of the Thirty Years' War.
