[1] After Italian Fascism (whose partisan arm, the National Fascist Party was well supported in the region) and the Allied invasion of Sicily during the World War II, Sicily increasingly became a stronghold of Christian Democracy, in opposition to the Italian Communist Party.
Sicilians had also a penchant for conservative/nationalist politics, represented mainly by the Monarchist National Party and the Italian Social Movement.
After the dissolution of these parties, in the early 1990s, the region was long governed by a " center-right coalition", notably including the Union of Christian and Centre Democrats, whose regional leader, Salvatore Cuffaro, served as President of Sicily from 2001 to 2008, Silvio Berlusconi's Forza Italia and the post-fascist National Alliance.
The popular election of the President and the relationship of confidence between him and the legislature, allow to identify the Sicilian model of government as a particular form of semi-presidential system.
On 19 March 2013 the Sicilian Regional Assembly decided to turn them into Free Associations of Municipalities (Liberi consorzi tra comuni).
Finally, on 30 July 2015 the Regional Assembly approved a law which put into force the Free Associations of Municipalities, regulating their functions and abolishing definitively the nine historical provinces.
[3] Sicily is also divided in 390 comuni (municipalities), which have even more history, having been established in the Middle Ages when they were the main places of government.
