The Kingdom of the Two Sicilies was located in today’s southern Italy. It included the island of Sicily and all of the Italian peninsula south of the Papal States. Ferdinando I, the first King of the Two Sicilies, had previously reigned over two kingdoms, as Ferdinando IV of the Kingdom of Naples and Ferdinando III of the Kingdom of Sicily. He had been deposed twice from the throne of Naples: once by the revolutionary Parthenopean Republic for six months in 1799 and again by Napoleon in 1805, before being restored in 1816 after the defeat of Napoleon. After the 1816 restoration, the two kingdoms were united into the Kingdom of the Two Sicilies.

Vittorio Emanuele II, King of Sardinia became a driving force behind the Italian unification movement along with Giuseppe Garibaldi, a general and nationalist, and Giuseppe Mazzini, a politician and journalist. Garibaldi conquered Naples and Sicily, the territories of the Kingdom of Two Sicilies. Francesco II, King of the Two Sicilies was deposed, the Kingdom of the Two Sicilies ceased to exist, and its territory was incorporated into the Kingdom of Sardinia. Eventually, the Sardinian troops occupied the central territories of the Italian peninsula, except Rome and part of Papal States. With all the newly acquired land, Vittorio Emanuele II was proclaimed the first King of the new, united Kingdom of Italy in 1861.
