Italy had never been a united nation prior to 1850. A battleground for the Great Powers after 1494, Italy was reorganized in 1815 at the Congress of Vienna. Austria received the northern provinces of Lombardy and Venetia. Sardinia and Piedmont fell under the rule of an Italian monarch, and Tuscany shared north-central Italy with several smaller states. The papacy ruled over central Italy and Rome, while a branch of the Bourbons ruled Naples and Sicily (Map 24.2).

After 1815 the goal of a unified Italian nation captivated many Italians, but there was no agreement on how it could be achieved. In 1848 the idealistic nationalist Giuseppe Mazzini’s efforts to form a democratic Italian republic were crushed by Austrian forces. Temporarily driven from Rome during the upheavals of 1848, a frightened Pope Pius IX (pontificate 1846–1878) turned against most modern trends, including national unification. At the same time, Victor Emmanuel, king of independent Sardinia, retained the moderate liberal constitution granted under duress in March 1848. To the Italian middle classes, Sardinia (see Map 24.2) appeared to be a liberal, progressive state ideally suited to drive Austria out of northern Italy and achieve the goal of national unification.

Sardinia had the good fortune of being led by Count Camillo Benso di Cavour. Cavour’s national goals were limited and realistic. Until 1859 he sought unity only for the states of northern and perhaps central Italy in a greatly expanded kingdom of Sardinia.

In the 1850s Cavour worked to consolidate Sardinia as a liberal constitutional state capable of leading northern Italy. He worked out a secret alliance with Napoleon III, and in July 1858 he goaded Austria into attacking Sardinia. The combined Franco-Sardinian forces were victorious, but Napoleon III decided on a compromise peace with the Austrians in July 1859 to avoid offending French Catholics by supporting an enemy of the pope. Sardinia would receive only Lombardy, the area around Milan. Cavour resigned in protest.

Popular revolts and Italian nationalism salvaged Cavour’s plans. While the war against Austria raged in the north, dedicated nationalists in central Italy had risen and driven out their rulers. Cavour returned to power in early 1860, and the people of central Italy voted overwhelmingly to join a greatly enlarged kingdom of Sardinia. Cavour had achieved his original goal of a north Italian state (see Map 24.2).

For superpatriots such as Giuseppe Garibaldi (1807–1882), the job of unification was still only half done. Having led a unit of volunteers to several victories over Austrian troops in 1859, Garibaldi emerged in 1860 as an independent force in Italian politics. (See “Individuals in Society: Giuseppe Garibaldi.”)

Secretly supported by Cavour, Garibaldi landed on the shores of Sicily in May 1860. His guerrilla band captured the imagination of the Sicilian peasantry, which rose in rebellion. Garibaldi captured Palermo and crossed to the mainland. When Garibaldi and Victor Emmanuel rode through Naples to cheering crowds, they symbolically sealed the union of north and south, of monarch and people.

The new kingdom of Italy, which did not include Venice until 1866 or Rome until 1870, was a parliamentary monarchy under Victor Emmanuel, neither radical nor democratic. Only a small minority of Italian males could vote. Despite political unity, the propertied classes and the common people were divided. A great social and cultural gap separated the industrializing north from the agrarian south.
