The War of the Spanish Succession was a European great power conflict, fought between 1701 and 1714. The death of Charles II of Spain in November 1700 without children resulted in a succession struggle between rival claimants. In his will, Charles named his heir as Philip of Anjou, who was backed by his grandfather Louis XIV. His opponent, Archduke Charles of Austria, was supported by the Grand Alliance. Significant related conflicts include the Great Northern War (1700–1721) and Queen Anne's War (1702–1713).
Although no longer the predominant power in Europe, the Spanish Empire remained a vast global power, including the Spanish Netherlands, large parts of Italy, the Americas and the Spanish East Indies. Its union with either France or Austria threatened the European balance of power, and the proclamation of Philip as king of Spain on 16 November 1700 led to war. Although by 1709 the Grand Alliance had forced France onto the defensive, Philip had confirmed his position in Spain, the ostensible cause of the war.
