Kingdom of the Two Sicilies
The Kingdom of the Two Sicilies lasted from 1815 until 1860, when it was annexed by the Kingdom of Sardinia to form the Kingdom of Italy in 1861. The capitals of the Two Sicilies were in Naples and in Palermo. The kingdom extended over the Mezzogiorno (the southern part of mainland Italy) and the island of Sicily. Jordan Lancaster notes that the integration of the Kingdom of the Two Sicilies into the Kingdom of Italy changed the status of Naples forever: "Abject poverty meant that, throughout Naples and Southern Italy, thousands decided to leave in search of a better future." Many went to the new world. The kingdom was heavily agricultural, like the other Italian states; the church owned 50–65% of the land by 1750.
Southern Italy
After Napoleon's defeat, King Ferdinand IV was restored by the Congress of Vienna of 1815 as Ferdinand I of the Two Sicilies. He established a concordat with the Papal States, which previously had a claim to the land. There were several rebellions on the island of Sicily against the King Ferdinand II but the end of the kingdom was only brought about by the Expedition of the Thousand in 1860, led by Garibaldi, an icon of the Italian unification, with the support of the House of Savoy and their Kingdom of Sardinia. The expedition resulted in a striking series of defeats for the Sicilian armies against the growing troops of Garibaldi. After the capture of Palermo and Sicily, he disembarked in Calabria and moved towards Naples, while in the meantime the Piedmontese also invaded the Kingdom from the Marche. The last battles fought were that of the Volturnus in 1860 and the siege of Gaeta, where King Francis II had sought shelter, hoping for French help, which never came. The last towns to resist Garibaldi's expedition were Messina (which capitulated on 13 March 1861) and Civitella del Tronto (which capitulated on 20 March 1861). The Kingdom of the Two Sicilies was dissolved and annexed to the new Kingdom of Italy, founded in the same year.
