What state existed from 1861, when King Victor Emmanuel II of Sardinia was proclaimed King of Italy, was the subject to the plotting of  an insurrection in Italian Eritrea by the government of Ethiopia?
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.
Duce Duce (] , "leader") is an Italian title, derived from the Latin word "dux", and cognate with "duke". National Fascist Party leader Benito Mussolini was identified by Fascists as "Il Duce" ("The Leader") of the movement. In 1925 it became a reference to the dictatorial position of "Sua Eccellenza Benito Mussolini, Capo del Governo, Duce del Fascismo e Fondatore dell'Impero" (""His Excellency Benito Mussolini, Head of Government, Leader of Fascism and Founder of the Empire""). Mussolini held this title together with that of President of the Council of Ministers: this was the constitutional position which entitled him to rule Italy on behalf of the King of Italy. "Founder of the Empire" was added for the exclusive use by Mussolini in recognition of his founding of an official legal entity of the Italian Empire on behalf of the King in 1936 following Italy's victory in the Second Italo-Ethiopian War. The position was held by Mussolini until 1943, when he was removed from office by the King and the position of "Duce" was dismantled, while Marshal Pietro Badoglio was appointed Presidente del Consiglio.
