The Capture of Rome on September 20, 1870, was the final event of the long process of Italian unification also known as the Risorgimento, marking both the final defeat of the Papal States under Pope Pius IX and the unification of the Italian peninsula under King Victor Emmanuel II of the House of Savoy.
The capture of Rome ended the approximate 1,116-year reign of the Papal States under the Holy See and is today widely memorialized throughout Italy with the Via XX Settembre street name in a considerable number of localities.
