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.
History of Islam in southern Italy
In 805, the imperial patrician of Sicily, Constantine, signed a ten-year truce with Ibrahim I ibn al-Aghlab, Emir of Ifriqiya, but this did not prevent Muslim fleets from other areas of Africa and Spain from attacking Sardinia and Corsica from 806–821. In 812, Ibrahim's son, Abdallah I, sent an invasion force to conquer Sicily. His ships were first harassed by the intervention of Gaeta and Amalfi and were later destroyed in great number by a tempest. However, they managed to conquer the island of Lampedusa and to ravage Ponza and Ischia in the Tyrrhenian Sea. A further agreement between the new patrician Gregorius and the emir established the freedom of commerce between southern Italy and Ifriqiya. After a further attack in 819 by Mohammed ibn-Adballad, cousin of Amir Ziyadat Allah I of Ifriqiya, no subsequent Muslim attacks on Sicily are mentioned by sources until 827.
