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.
List of monarchs of Sicily
Peter III of Aragon, Manfred's son in law, of the House of Barcelona, conquered the island of Sicily from Charles I in 1282 and had himself crowned King of Sicily. Thereafter the old Kingdom of Sicily was centred on the mainland, with capital at Naples, and although informally called Kingdom of Naples it was still known formally as "Kingdom of Sicily". Thus, there were two "Sicilies" — the island kingdom, however, was often called "Sicily beyond the Lighthouse" or "Trinacria", by terms of a treaty between the two states.
