It was the first great battle in the War of the Spanish Succession (1701-1714), which was carried on mainly in Italy, the Netherlands, and Germany. This war followed closely upon the War of the Palatinate, which ended with the Treaty of Ryswick, in 1697. To this peace Louis XIV of France--the most powerful monarch in Europe, who, in spite of his brutal conduct of the war, had really been a loser by it--gave his consent. Among the concessions made by him was his recognition--much against his own interest--of William III as the rightful King of England. Louis gave his consent to the Treaty of Ryswick partly because of his interest in the question of the Spanish succession. Charles II of Spain--last of the Hapsburg line in that country--was childless, and there were three claimants for the throne; namely, Philip of Anjou, grandson of Louis XIV; the Electoral Prince of Bavaria; and Charles, son of Leopold I of Germany, Emperor of the Holy Roman Empire. The real stake was the "balance of power" in Europe. At last, after much wrangling and intrigue among the courts, Charles II bequeathed his throne to the Bavarian Prince, whose death, in 1699, left Europe still divided over the succession. Finally, Louis XIV completely won Charles II to his side, and Philip of Anjou was named in Charles' will as his heir. Louis accepted for Philip, who was crowned at Madrid, in 1701, as Philip V, and Europe was stirred to wrath by the greed of the already too powerful French King. Turning now upon England, Louis, in violation of the Treaty of Ryswick, declared the son of the exiled James II rightful king of that country. The result of Louis' acts was the Grand Alliance of The Hague against France, formed between England, Holland, Prussia, the Holy Roman Empire, Portugal, and Savoy. On the side of the allies in the war that followed, the great generals were the English Duke of Marlborough, Prince Eugene of Savoy, and Hensius, Pensioner of Holland. France had lost her best generals by death, and Louis was compelled to rely upon inferior men as leaders of his army. War was formally declared against France by the allies May 4, 1702. The early operations were carried on in Flanders, in Germany--on the Upper Rhine--and in Northern Italy. Marlborough headed the allied troops in Flanders during the first two years of the war, and took some towns from the enemy, but nothing decisive occurred. Nor did any actions of importance take place during this period between the rival armies in Italy. But in the centre of that line from north to south, from the mouth of the Schelde to the mouth of the Po, along which the war was carried on, the generals of Louis XIV acquired advantages in 1703 which threatened one chief member of the Grand Alliance with utter destruction.
