No sooner had the marriage been annulled than his titanic ambition leaped, as it always did, to a tremendous pinnacle. He would wed. He would have children. But he would wed no petty princess. This man who in his early youth had felt honored by a marriage with the almost declassee widow of a creole planter now stretched out his hand that he might take to himself a woman not merely royal but imperial. At first he sought the sister of the Czar of Russia; but Alexander entertained a profound distrust of the French emperor, and managed to evade the tentative demand. There was, however, a reigning family far more ancient than the Romanoffs--a family which had held the imperial dignity for nearly six centuries--the oldest and the noblest blood in Europe. This was the Austrian house of Hapsburg. Its head, the Emperor Francis, had thirteen children, of whom the eldest, the Archduchess Marie Louise, was then in her nineteenth year. Napoleon had resented the rebuff which the Czar had given him. He turned, therefore, the more eagerly to the other project. Yet there were many reasons why an Austrian marriage might be dangerous, or, at any rate, ill-omened. Only sixteen years before, an Austrian arch-duchess, Marie Antoinette, married to the ruler of France, had met her death upon the scaffold, hated and cursed by the French people, who had always blamed "the Austrian" for the evil days which had ended in the flames of revolution. Again, the father of the girl to whom Napoleon's fancy turned had been the bitter enemy of the new regime in France. His troops had been beaten by the French in five wars and had been crushed at Austerlitz and at Wagram. Bonaparte had twice entered Vienna at the head of a conquering army, and thrice he had slept in the imperial palace at Schonbrunn, while Francis was fleeing through the dark, a beaten fugitive pursued by the swift squadrons of French cavalry. The feeling of Francis of Austria was not merely that of the vanquished toward the victor. It was a deep hatred almost religious in its fervor. He was the head and front of the old-time feudalism of birth and blood; Napoleon was the incarnation of the modern spirit which demolished thrones and set an iron heel upon crowned heads, giving the sacred titles of king and prince to soldiers who, even in palaces, still showed the swaggering brutality of the camp and the stable whence they sprang. Yet, just because an alliance with the Austrian house seemed in so many ways impossible, the thought of it inflamed the ardor of Napoleon all the more. "Impossible?" he had once said, contemptuously. "The word 'impossible' is not French."
