Spain and France sign the Peace of the Pyrenees. This ends the warfare between the two countries that had continued after the Peace of Westphalia, due to French involvement in the Revolt of the Catalans (1640-52) and Spanish involvement in the Fronde (1648-53). It marks the ascendance of France as the dominant power in Europe, as according to its terms, France obtains Rousillon, Cerdagne, Artois and fortresses in Hainault, Flanders and Luxembourg. Spain resigns her claims to Alsace. It agrees that Louis XIV will marry Maria-Theresa, Philip IV's eldest daughter, on the condition that she renounces her claim to the Spanish throne in return for a dowry.
