The Peace of Westphalia (German: Westfälischer Friede) was a series of peace treaties signed between May and October 1648 in the Westphalian cities of Osnabrück and Münster. These treaties 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, with Spain formally recognizing the independence of the Dutch Republic.
