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.
Subalpine Senate The Subalpine Senate was the upper house of the Kingdom of Sardinia and one of the two houses of its bicameral parliament - the other was the Chamber of Deputies. It was set up in 1848 and dissolved in 1861, to be replaced by the Senate of the Kingdom of Italy - it is the direct ancestor of the present Italian Senate. Its name was a reference to the Napoleonic Subalpine Republic.
