The question of what year was Italy unified is central to understanding the modern Italian state. While the answer, 1861, marks the official proclamation of the Kingdom of Italy, the reality is a complex tapestry of wars, diplomacy, and regional identities that spanned nearly a century. The peninsula was a fractured landscape of city-states, papal territories, and foreign-controlled regions, and the journey to consolidate this into a single nation was a profound historical event.
The Fragmented Peninsula
Before delving into the unification process, it is essential to grasp the fragmented nature of pre-unification Italy. The territory was not a single political entity but a collection of distinct regions with their own histories and rulers. The north was dominated by the Kingdom of Sardinia, a constitutional monarchy based in Turin, which held significant territories including the island of Sardinia. Central Italy was a patchwork of duchies and the Papal States, the latter ruled directly by the Pope. In the south, the Kingdom of the Two Sicilies, a Bourbon monarchy, stretched across both the mainland and the island of Sicily. This political disunity made the peninsula vulnerable to external influence, particularly from the Austrian Empire, which controlled key northern territories.
The Role of Sardinia and Cavour
The engine of Italian unification was the Kingdom of Sardinia, under the strategic leadership of Prime Minister Count Camillo di Cavour. Cavour was a pragmatic statesman who modernized the Sardinian economy and built a strong alliance with France. His primary goal was to expel Austrian influence from the Italian peninsula. This objective was achieved through the Second Italian War of Independence in 1859, where a Franco-Sardinian alliance defeated the Austrians. The subsequent Treaty of Villafranca, however, resulted in Lombardy being annexed by Sardinia, while Austria retained control of Venetia, demonstrating the limits of military victory without total conquest.
Garibaldi and the Southern Expedition
While Cavour operated in the diplomatic and military arenas, the popular will for unification was vividly demonstrated by Giuseppe Garibaldi. This revolutionary leader and his volunteer force, the Thousand, landed in Sicily in 1860. Garibaldi’s campaign was a remarkable feat of popular mobilization, quickly conquering the Kingdom of the Two Sicilies with astonishing speed. His success created a fait accompli that forced the hand of the conservative Cavour. Recognizing the momentum of the southern revolt, Cavour’s forces moved to annex the conquered territories, integrating the south into the expanding kingdom.
The Proclamation of 1861
The stage was now set for the political culmination of the Risorgimento. On March 17, 1861, the Parliament of the Kingdom of Sardinia proclaimed the Kingdom of Italy, with Victor Emmanuel II of the House of Savoy as its king. This date, 1861, is universally recognized as the official birth of the modern Italian state. The choice of Turin as the capital further solidified the dominance of the Savoyard legacy. However, this proclamation was more of a symbolic milestone than a geographical reality, as a significant portion of the desired "Italia irredenta" (unredeemed Italy) remained outside the new kingdom's borders.
Completion of the Unification
Although 1861 marks the formal unification, the process was not complete until 1870. The final major obstacle was the Papal States, which had resisted incorporation. The withdrawal of French troops from Rome during the Franco-Prussian War provided the opportunity for Italian forces to enter the city. In 1870, Italian troops breached the walls at Porta Pia, and Rome was annexed, serving as the definitive capital of the kingdom. This event effectively eliminated the last major sovereign entity that had opposed Italian unification, cementing the territorial integrity of the state.
