But the new emperor, while thus actively engaged in labors of peace means lived up to the spirit of his motto, “The Empire is peace.” An empire founded upon the army needs to give employment to that army. A monarchy sustained by the votes of a people athirst for glory needs to do something to appease that thirst. A throne filled by a Napoleon could not safely ignore the “Napoleonic Ideas,” and the first of these might be stated as “The Empire is war.” And the new emperor was by no means satisfied to pose simply as the “nephew of his uncle.” He possessed a large share of the Napoleonic ambition, and hoped by military glory to surround his throne with some of the luster of that of Napoleon the First. Whatever his private views, it is certain that France under his reign became the most aggressive nation of Europe, and the overweening ambition and self-confidence of the new emperor led him to the same end as his great uncle, that of disaster and overthrow. He was evidently bent on playing a leading part in European politics, showing the world that one worthy to bear the name of Napoleon was on the throne. The very beginning of Louis Napoleon’s career of ambition, as president of the French Republic, was signalized by an act of military force, in sending an army to Rome and putting an end to the attempted Italian republic. These troops were kept there until 1866, and the aspirations of the Italian patriots were held in check until that year. Only when United Italy stood menacingly at the gates of Rome were these foreign troops withdrawn. They had retarded, perhaps, for a time the inevitable union of the Italian states into a single kingdom; they certainly prevented the establishment of a republic. In 1854 Napoleon allied himself with the British and the Turks against Russia, and sent an army to the Crimea, which played an effective part in the great struggle in that peninsula. The troops of France had the honor of rendering Sebastopol untenable, carrying by storm one of its two great fortresses and turning its guns upon the city. WAR WITH AUSTRIA
