Pyrenees, Treaty of the

(November 7, 1659) Peace treaty between France and Spain. From the end of the Thirty Years' War (1648) until 1659, Spain and France fought almost continuously. When Philip IV of Spain did not receive the expected Habsburg support against France, he concluded a peace settlement that ceded border regions to France. The treaty also involved a marriage compact between Louis XIV and the Spanish infanta Maria Teresa, which established Louis as the most powerful monarch in Europe.
