War of Devolution
Both France and the Dutch Republic viewed the Spanish Netherlands as essential for their security and trade, making it a contested area throughout the 17th century. France occupied much of it in the 1667 to 1668 War of Devolution, before returning it to Spain in the 1668 Treaty of Aix-la-Chapelle. After this, Louis XIV decided the best way to force concessions from the Dutch was by defeating them first.
