The accession of William III began a revolution in English foreign policy. Under the Dutch king's auspices England joined a Grand Alliance against the France of Louis XIV and shouldered the burdens of a principal partner in a major continental war. Not only did the war place grave financial strains upon the state; the formulation, administration, and execution of war policy also became areas of continual concern. These concerns combined to raise general questions about England's proper role in European affairs and about the proper application of English power in service of those interests. They also cast William III and the politicians into a constitutional no-man's land in which the royal monopoly over war and peace had to contest with the need to secure annual supplies. It has been the historian's task to explain how William III's “continental commitment” to land warfare, alliances, and defense of European liberties survived this political struggle.
