Prince Metternich declared soon after the peace of 1815 that Italy was 'only a geographical expression.' The taunt was true at the time, but even then there was a young dreamer living who was destined to render it false. 'Great ideas,' declared Mazzini, 'create great nations,' and his whole career was devoted to the attempt to bring about a united Italy. The statesmanship of Cavour and the sword of Garibaldi were enlisted in the same sacred cause. The petty governments of the Peninsula grew suddenly impossible, and Italy was freed from native tyranny and foreign domination. Austria, not content with the possession of Lombardy, which was ceded to her by the treaty of 1815, had made her power felt in almost every direction, and even at Naples her authority prevailed. The Austrians were not merely an alien but a hated race, for they stood between the Italian people and their dream of national independence and unity, and native despotism could always count on their aid in quelling any outbreak of the revolutionary spirit. The governments of the country, Austria and the Vatican apart, were rendered contemptible by the character of its tyrannical, incapable, and superstitious rulers, but with the sway of such powers of darkness Sardinia presented a bright contrast. The hopes of patriotic Italians gathered around Victor Emmanuel II., who had fought gallantly at Novara in 1849, and who possessed more public spirit and common-sense than the majority of crowned heads. Victor Emmanuel ascended the throne of Sardinia at the age of twenty-eight, immediately after the crushing disaster which seemed hopelessly to have wrecked the cause of Italian independence. Although he believed, with Mazzini, that there was only room for two kinds of Italians in Italy, the friends and the enemies of Austria, he showed remarkable self-restraint, and adopted a policy of conciliation towards foreign Powers, whilst widening the liberties of his own subjects until all over the land Italians came to regard Sardinia with admiration, and to covet 'liberty as it was in Piedmont.'
