Grand Alliance, War of the, 1688-97, war between France and a coalition of European powers, known as the League of Augsburg (and, after 1689, as the Grand Alliance). Louis XIV of France took advantage of the absence of Emperor Leopold I on a campaign against the Turks and of the promised support of James II of England to invade the empire and devastate (1689) the Palatinate. The revolution in England overthrew James, and William, prince of Orange, became William III of England (1688-89). In an attempt to keep William from leading troops to the Continent, Louis supported a counterrevolution in Ireland but was frustrated at the battle of the Boyne (1690). The naval war, of which the first major battle was the French victory at Beachy Head (1690), was practically ended by the English victory of La Hogue (1692). On land, however, Louis and Vauban took Namur (1692); Marshal Luxembourg was victorious at Fleurus (1690) over the Dutch and at Steenkerke (1692) and Neerwinden (1693) over William III; and the duke of Savoy was defeated at Marsaglia by Catinat (1693), while another French army entered Catalonia. The exhaustion of the belligerents and the defection of Savoy from the Grand Alliance (1696) finally led to the Treaty of Ryswick. This war was known on the American continent as King William's War (see French and Indian Wars).

(1689–97) Third major war of Louis XIV of France, in which his expansionist plans were blocked by an alliance led by Britain, the United Provinces of the Netherlands, and the Austrian Habsburgs. The deeper issue underlying the war was the rivalry between the Bourbon and Habsburg dynasties. Louis launched a campaign in the 1680s to position the Bourbons for future succession to the Spanish throne. To oppose him, the Habsburg emperor Leopold I joined other European nations in the League of Augsburg. The league proved ineffective, but in 1690 Britain, Brandenburg, Saxony, Bavaria, and Spain, alarmed at Louis's successes, joined with Leopold to form the Grand Alliance. As war broke out in Europe and in overseas colonies, including America (see King William's War), Louis found his military inadequately prepared, and France suffered heavy naval losses. In 1695 Louis started secret peace negotiations, which culminated in the Treaty of Rijswijk (1697). The underlying conflict between the Habsburg and Bourbon rulers and English-French conflicts remained unresolved and resurfaced four years later in the War of the Spanish Succession.
