Département of the French Empire: first as Département du Tibre (1808–1810) and then as Département Rome (1810–1814). After the fall of Napoleon, the Papal States were reconstituted by a decision of the Congress of Vienna of 1814. In 1849, a second Roman Republic was proclaimed during a year of revolutions in 1848. Two of the most influential figures of the Italian unification, Giuseppe Mazzini and Giuseppe Garibaldi, fought for the short-lived republic. Rome then became the focus of hopes of Italian reunification after the rest of Italy was united as the Kingdom of Italy in 1861 with the temporary capital in Florence. That year Rome was declared the capital of Italy even though it was still under the Pope's control. During the 1860s, the last vestiges of the Papal States were under French protection thanks to the foreign policy of Napoleon III. French troops were stationed in the region under Papal control. In 1870 the French troops were withdrawn due to the outbreak of the Franco-Prussian War. Italian troops were able to capture Rome entering the city through a breach near Porta Pia. Pope Pius IX declared himself a prisoner in the Vatican. In 1871 the capital of Italy was moved from Florence to Rome. In 1870 the population of the city was 212,000, all of whom lived with the area circumscribed by the ancient city, and in 1920, the population was 660,000. A significant portion lived outside the walls in the north and across the Tiber in the Vatican area. Soon after World War I in late 1922 Rome witnessed the rise of Italian Fascism led by Benito Mussolini, who led a march on the city. He did away with democracy by 1926, eventually declaring a new Italian Empire and allying Italy with Nazi Germany in 1938. Mussolini demolished fairly large parts of the city centre in order to build wide avenues and squares which were supposed to celebrate the fascist regime and the resurgence and glorification of classical Rome. The interwar period saw a rapid growth in the city's population which surpassed one million inhabitants soon after 1930. During World War II, due to the art treasuries and the presence of the Vatican, Rome largely escaped the tragic destiny of other European cities. However, on 19 July 1943, the San Lorenzo district was subject to Allied bombing raids, resulting in about 3,000 fatalities and 11,000 injuries, of whom
