When Did the Unification of Italy Take Place? Key Dates Explained

The unification of Italy was formally completed in 1871, when Rome became the capital of the newly consolidated Kingdom of Italy. The process developed over several decades, with major milestones including the proclamation of the Kingdom of Italy in 1861 and the annexation of Rome in 1870. These events ended centuries of political division on the Italian peninsula.

The movement for unification, known as the Risorgimento, grew in the 19th century through nationalist sentiment, diplomatic efforts, and military campaigns. In 1861, most Italian states were united under King Victor Emmanuel II, forming the Kingdom of Italy. This followed military successes in the north and a strategic alliance between the Kingdom of Sardinia and other pro-unification groups. At that time, Venetia and Rome were still not part of the kingdom.

In 1860, Giuseppe Garibaldi led the Expedition of the Thousand, a key turning point. With a volunteer force, he landed in Sicily and overthrew the Bourbon rulers of the Kingdom of the Two Sicilies. His troops then moved north and transferred control of southern Italy to Victor Emmanuel II, greatly expanding the kingdom’s territory. This campaign showed that popular uprisings and military action could achieve unification where diplomacy alone had not.

Venetia joined Italy in 1866, after the Austro-Prussian War. Italy had allied with Prussia against Austria. Despite poor military performance, Italy gained Venetia due to Prussia’s victory. The last major addition came in 1870, when French troops left Rome because of the Franco-Prussian War. Italian forces entered the city and annexed it, ending the Pope’s secular authority. Rome was named the capital in 1871, completing the unification.

Leaders such as Count Camillo di Cavour used diplomacy to secure support from stronger European powers. Garibaldi built mass support through direct military action. Victor Emmanuel II provided a central figure as monarch, helping to unify regions with diverse histories and loyalties.
