The Kingdom of the Two Sicilies (Neapolitan: Regno dê Doje Sicilie; Sicilian: Regnu dî Dui Sicili; Italian: Regno delle Due Sicilie; Spanish: Reino de las Dos Sicilias) was a kingdom in Southern Italy from 1816 to 1860. The kingdom was the largest sovereign state by population and size in Italy before Italian unification, comprising Sicily and all of the Italian Peninsula south of the Papal States, which covered most of the area of today's Mezzogiorno. The Two Sicilies were heavily agricultural, like the other Italian states.
