The revolutions of 1848, known in some countries as the springtime of the peoples or the springtime of nations, were a series of revolutions throughout Europe over the course of more than one year, from 1848 to 1849. It remains the most widespread revolutionary wave in European history to date.

The Kingdom of Italy was a state that existed from 17 March 1861, when Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 12 June 1946, when the monarchy was abolished, following civil discontent that led to an institutional referendum on 2 June 1946, which resulted in a modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the Risorgimento. That process was influenced by the Savoy-led Kingdom of Sardinia, which can be considered Italy's legal predecessor state.
