Because Wikipedia is a collaboratively edited platform, its articles are subject to frequent changes and minor wording adjustments. However, based on the most stable and recent consensus versions of the article "Peace of Westphalia" (the title to which "Treaty of Westphalia" redirects), the first two paragraphs read as follows:

The Peace of Westphalia (German: Westfälischer Friede, pronounced [vɛstˈfɛːlɪʃɐ ˈfʁiːdə]) is the collective name for two peace treaties signed in October 1648 in the Westphalian cities of Osnabrück and Münster. They ended the Thirty Years' War (1618–1648) and brought peace to the Holy Roman Empire, closing a calamitous period of European history that killed approximately eight million people. The Eighty Years' War (1568–1648) was also ended by the Peace of Münster, which is usually considered to be part of the Peace of Westphalia.

The negotiation process was lengthy and complex. Talks took place in two cities, because each side wanted to meet on territory under its own control. A total of 109 delegations arrived to represent the belligerent states, but not all delegations were present at the same time. Three treaties were signed to end each of the overlapping wars: the Peace of Münster, the Treaty of Münster, and the Treaty of Osnabrück. These treaties ended the Thirty Years' War and the Eighty Years' War.
