In 1866, following the Third Independence War, territories of Veneto, Friuli and Mantua were annexed. There were therefore nine more provinces: Belluno, Mantua, Padua, Rovigo, Treviso, Venice, Verona, Vicenza and Udine, all previously part of the Austrian Empire. Eventually, in 1870, following the union of Rome and its province from the Papal States, the provinces rose in number to 69. After the World War I, new territories were annexed to Italy. The province of Trento was created in 1923. Provinces of La Spezia and Trieste in 1923, while Ionio in 1924. In 1924 the new provinces of Fiume, Pola, and Zara were created, increasing the total number of provinces in Italy to 76.
