While these exciting events were taking place in the north, Italy was swept with a storm of revolution from end to end. Metternich was no longer at hand to keep it in check, and the whole peninsula seethed with revolt. Sicily rejected the rule of the Bourbon king of Naples, chose the Duke of Genoa, son of Charles Albert of Sardinia, for its king, and during a year fought for liberty. This patriotic effort of the Sicilians ended in failure. The Swiss mercenaries of the Neapolitan king captured Syracuse and brought the island into subjection, and the tyrant hastened to abolish the constitution which he had been frightened into granting in his hour of extremity. In the north of Italy war broke out between Austria and Sardinia. Milan and Venice rose against the Austrians and drove out their garrisons, throughout Lombardy the people raised the standard of independence, and Charles Albert of Sardinia called his people to arms and invaded that country, striving to free it and the neighboring state of Venice from Austrian rule. For a brief season he was successful, pushing the Austrian troops to the frontiers, but the old Marshal Radetzky defeated him at Verona and compelled him to seek safety in flight. The next year he renewed his attempt, but with no better success. Depressed by his failure, he resigned the crown to his son Victor Emmanuel, who made a disadvantageous peace with Austria. Venice held out for several months, but was finally subdued, and Austrian rule was restored in the north. [=The Revolution in Rome=] Meanwhile the pope, Pius IX., offended his people by his unwillingness to aid Sardinia against Austria. He promised to grant a constitutional government and convened an Assembly in Rome, but the Democratic people of the state were not content with feeble concessions of this kind. Rossi, prime minister of the state, was assassinated, and the pope, filled with alarm, fled in disguise, leaving the Papal dominion to the revolutionists, who at once proclaimed a republic and confiscated the property of the Church. Mazzini, the leader of "Young Italy," the ardent revolutionist who had long worked in exile for Italian independence, entered the Eternal City, and with him Garibaldi, long a political refugee in America and a gallant partisan leader in the recent war with Austria. The arrival of these celebrated revolutionists filled the democratic party in Rome with the greatest enthusiasm, and it was resolved to defend the States of the Church to the last extremity, viewing them as the final asylum of Italian liberty.
