The Franco-Spanish War of 1635 to 1659 was one of a series of wars between France, and their Habsburg rivals in Spain and the Holy Roman Empire. It is considered a connected conflict of the 1568 to 1648 Dutch Revolt, and 1618 to 1648 Thirty Years War. Though some minor territorial gains were made by France, the war ended inconclusively in 1659 with the Treaty of the Pyrenees.
Major areas of conflict included Northern Italy, the Spanish Netherlands, Catalonia, and the Rhineland. Spain financed French Huguenot rebellions from 1622 to 1630, and the 1648 to 1653 civil war known as the Fronde; France supported revolts against Spanish rule in Portugal, Catalonia and Naples.
While France supported Habsburg opponents in the Dutch Revolt and Thirty Years War, it avoided direct involvement until 1635, when it agreed alliances with the Swedes and Dutch. After these ended in the 1648 Peace of Westphalia, fighting continued between Spain and France, with neither able to gain an advantage.
The 1657 Anglo-French alliance led to an offensive in Flanders, and victory at the June 1658 Battle of the Dunes.
