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.
Sicilian language
When the two most famous of Southern Italy's Norman adventurers, Roger of Hauteville and his brother, Robert Guiscard, began their conquest of Sicily in 1061, they already controlled the far south of Italy (Apulia and Calabria). It took Roger 30 years to complete the conquest of Sicily (Robert died in 1085). In the aftermath of the Norman conquest of Sicily, the revitalization of Latin in Sicily had begun, and some Norman and Norman-French words would be absorbed: but many etymologies are disputed and the only sure marker of a typical Norman word is its Scandinavian origin, such words do not exist in Sicilian.
