Because Wikipedia is a living, dynamically edited encyclopedia, the exact wording of its articles can change from day to day. However, based on the most stable and recent version of the article (which is officially titled "Peace of Westphalia", where "Treaty of Westphalia" redirects), the first two paragraphs are 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 Holy Roman Emperor (Ferdinand III), the Spanish monarchy, the kingdoms of France and Sweden, and their respective allies among the princes of the Holy Roman Empire participated in these treaties.

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 were present at the same time. Two treaties were signed to end the war in the Empire: the Treaty of Münster and the Treaty of Osnabrück. These treaties ended the Thirty Years' War in the Holy Roman Empire, with the Habsburgs and their Catholic allies on one side, battling the Protestant powers (Sweden, Denmark, Dutch, and Holy Roman principalities) allied with France (Catholic but anti-Habsburg). The treaties also joined the Peace of Münster, which ended the Eighty Years' War between Spain and the Dutch Republic, into an overarching settlement of the European conflicts.
