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
In 535, Justinian I made Sicily a Byzantine province, which returned the Greek language to a position of prestige, at least on an official level. At this point in time the island could be considered a border zone with high levels of bilingualism: Latinisation was mostly concentrated in western Sicily, whereas Eastern Sicily remained predominantly Greek. As the power of the Byzantine Empire waned, Sicily was progressively conquered by Saracens from North Africa ("Ifriqiya"), from the mid 9th to mid 10th centuries. The Emirate of Sicily persisted long enough to develop a distinctive local variety of Arabic, Siculo-Arabic (at present extinct in Sicily but surviving as the Maltese language). Its influence is noticeable in around 100 Sicilian words, most of which relate to agriculture and related activities. This is understandable because of the Arab Agricultural Revolution; the Saracens introduced to Sicily their advanced irrigation and farming techniques and a new range of crops, nearly all of which remain endemic to the island to this day.
