Italy’s three capitals

The unification of Italy followed the events of the years 1860 and 1861.
At the first convocation of the Italian Parliament (in February 1861), Vittorio Emanuele II was proclaimed king of Italy.
In 1866, after the Third Independence War, Veneto and part of Lombardy were taken from the Austrian-Hungarian Empire and incorporated into the Italian kingdom.
In 1870, with the defeat of Rome, Lazio was subtracted from the Church State and included in the Italian Kingdom.
Roma became the official capital of Italy, after Torino, which was the capital city from 1861 to 1865, and Firenze, capital from 1865 to 1870.
