Prague, Peace of, 1635

The Peace of Prague, dated 30 May 1635 Old Style, was a significant turning point in the Thirty Years' War. Signed by John George I, Elector of Saxony, and Ferdinand II, Holy Roman Emperor, the terms ended Saxony's support for the anti-Imperial coalition led by Sweden. Other states within the Holy Roman Empire subsequently joined the treaty, and their exit was a key factor in Catholic France entering the war as an ally of Protestant Sweden. Although fighting continued until 1648, it is generally agreed Prague ended the war as primarily one of religion.
