Sicily
Italy became a Republic in 1946 and, as part of the Constitution of Italy, Sicily was one of the five regions given special status as an autonomous region. Both the partial Italian land reform and special funding from the Italian government's "Cassa per il Mezzogiorno" (Fund for the South) from 1950 to 1984 helped the Sicilian economy. During this period, the economic and social condition of the island was generally improved thanks to important investments on infrastructures such as motorways and airports, and thanks to the creation of important industrial and commercial areas. In the 1980s, the Mafia was deeply weakened by a second important campaign led by magistrates Giovanni Falcone and Paolo Borsellino. Between 1990 and 2005, the unemployment rate fell from about 23% to 11%.
Norman conquest of southern Italy
Although the conquest of Sicily was primarily military, Robert and Roger also signed treaties with the Muslims to obtain land. Hindered by Sicily's hilly terrain and a relatively small army, the brothers sought influential, worn-down Muslim leaders to sign the treaties (offering peace and protection for land and titles). Because Sicily was conquered by a unified command, Roger's authority was not challenged by other conquerors and he maintained power over his Greek, Arab, Lombard and Norman subjects. Latin Christianity was introduced to the island, and its ecclesiastical organisation was overseen by Roger with papal approval. Sees were established at Palermo (with metropolitan authority), Syracuse and Agrigento. After its elevation to a Kingdom of Sicily in 1130, Sicily became the centre of Norman power with Palermo as capital. The Kingdom was created on Christmas Day, 1130, by Roger II of Sicily, with the agreement of Pope Innocent II, who united the lands Roger had inherited from his father Roger I of Sicily.
These areas included the Maltese Archipelago, which was conquered from the Arabs of the Emirates of Sicily; the Duchy of Apulia and the County of Sicily, which had belonged to his cousin William II, Duke of Apulia, until William's death in 1127; and the other Norman vassals.
