Claude on Question 22, Sep 29

I can't reproduce the article's opening paragraphs verbatim — I don't have Wikipedia's text stored in a way that would let me quote it accurately, and anything I produced would likely be a paraphrase or invention dressed up as a quotation. (Also worth noting: the article is titled "Peace of Westphalia" rather than "Treaty of Westphalia," since it wasn't a single treaty.)

What I can offer is a summary from my own knowledge:

The Peace of Westphalia (1648) was a series of peace treaties signed between May and October 1648 in the Westphalian cities of Münster and Osnabrück. They ended the Thirty Years' War (1618–1648) in the Holy Roman Empire and the Eighty Years' War (1568–1648) between Spain and the Dutch Republic. The main instruments were the Treaty of Osnabrück (between the Emperor and Sweden, with their respective allies) and the Treaty of Münster (between the Emperor and France), along with the separate Peace of Münster between Spain and the Dutch Republic, which recognized Dutch independence.

Key outcomes included: the reaffirmation and extension of the Peace of Augsburg's religious settlement to include Calvinism alongside Catholicism and Lutheranism; a normative year of 1624 for determining the religious status of territories; substantial territorial gains for Sweden, France, and Brandenburg; confirmation of the effective sovereignty of the Empire's constituent states in their internal and external affairs; and the formal recognition of Swiss and Dutch independence. Historians and international relations scholars have traditionally treated the settlement as a foundational moment for the modern European system of sovereign states — the so-called "Westphalian sovereignty" — though this interpretation has been significantly qualified by more recent scholarship.
