Kingdom of Italy Is Proclaimed

Context

The Italian peninsula had remained politically fragmented for centuries, divided among the Kingdom of Sardinia, the Papal States, the Kingdom of the Two Sicilies, Austrian-controlled territories, and smaller duchies. The Risorgimento movement of the nineteenth century sought national unification, drawing strength from liberal reforms in Sardinia and popular uprisings elsewhere. Camillo Benso, Count of Cavour, as prime minister of Sardinia, pursued diplomatic alliances and military campaigns to advance the cause, while Giuseppe Garibaldi mobilized volunteer forces in the south.

What Happened

After the Second Italian War of Independence in 1859 and Garibaldi’s Expedition of the Thousand in 1860, plebiscites across northern and southern provinces approved annexation to the Kingdom of Sardinia. On February 18, 1861, the new parliament—still formally the Parliament of the Kingdom of Sardinia—convened in Turin at Palazzo Carignano and included deputies from the recently annexed regions. Cavour introduced a brief bill on February 21 declaring that Victor Emmanuel II would assume the title King of Italy for himself and his successors.

Aftermath

The measure became Law No. 4761 on March 17, 1861, and was published in the official gazette. Victor Emmanuel retained the numeral “II” to emphasize dynastic continuity under the House of Savoy and the Statuto Albertino constitution. Turin remained the capital of the new kingdom, which now encompassed the former Sardinian territories plus most of the peninsula except Rome and Venetia.

Legacy

The proclamation created the modern Italian nation-state and completed the first major phase of unification. It established a precedent for national consolidation through parliamentary action and plebiscites, later enabling the acquisition of Venetia in 1866 and Rome in 1870. The Kingdom of Italy endured as a constitutional monarchy until the abolition of the monarchy in 1946.
