Map of Italy after the Second War of Independence, also known as the Austro-Sardinian War of 1859, and the Proclamation of the Kingdom of Italy on March 17, 1861
When Victor Emanuel was crowned king of the new nation, there were 59 provinces. New names were given to former provinces of the Kingdom of the Two Sicilies. The former names are listed at the bottom. Areas such as Venetia (under Austrian control) and the much reduced Papal States were not part Italy at that time.

Following the Third War of Independence, the territories of Veneto, Friuli and Mantua were annexed, all previously part of the Austrian Empire. Nine more provinces were added: Belluno, Mantua, Padua, Rovigo, Treviso, Venice, Verona, Vicenza and Udine. Eventually, in 1870, following the union of Rome and its province from the Papal States, the provinces rose in number to 69.

After the conclusion of World War I in 1918, new territories were annexed to Italy. The province of Trento was created in 1920. The provinces of La Spezia, Trieste and Enna in 1923. In 1924 the new provinces of Fiume, Pola and Zara were established, increasing the total number of provinces in Italy to 76.
In 1927, following a royal charter, a general province rearrangement took place. Seventeen new provinces were created: Aosta, Vercelli, Varese, Savona, Bolzano, Gorizia, Pistoia, Pescara, Rieti, Terni, Viterbo, Frosinone, Brindisi, Matera, Ragusa, Enna, and Nuoro. The province of Caserta was suppressed, that is, eliminated.
