Kingdom of Italy The Kingdom of Italy (Italian: "Regno d'Italia" ) was a state which existed from 1861, when King Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 1946, when a constitutional referendum led civil discontent to abandon the monarchy and form the Italian Republic. The state was founded as a result of the unification of Italy under the influence of the Kingdom of Sardinia, which can be considered its legal predecessor state.
Roman Republic (19th century) The Roman Republic was a short-lived state declared on February 9, 1849, when the government of Papal States was temporarily replaced by a republican government due to Pope Pius IX's flight to Gaeta. The republic was led by Carlo Armellini, Giuseppe Mazzini, and Aurelio Saffi. Together they formed a triumvirate, a reflection of a form of government seen in the ancient Roman Republic.
