Silvio Milazzo (Caltagirone, September 4, 1903 – December 24, 1982) was an Italian Christian Democrat politician and the President of the Regional Government of Sicily from 1958-1960.
Milazzo was a landowner from Caltagirone and sat in the Sicilian regional parliament since 1947 for the Christian Democrat Party (DC) in the political current of Mario Scelba. He was the Regional Minister for Public Works and for Agriculture in the regional governments of Franco Restivo (1949-1955), Giuseppe Alessi (1955-1956) and Giuseppe La Loggia (1956-1958). He was a reliable party loyalist up to the time former Italian Premier Amintore Fanfani began to bring in bright young men from Rome into Sicily's Christian Democratic organization. Outraged by this infringement on Sicilian autonomy and threat to Sicilian patronage, Milazzo became the gullible protagonist of Sicilian autonomy.
After the regional elections of 1955, Milazzo, supported by the left and dissident Christian democrats, surprisingly had won the vote for head of the regional government against the outgoing president Restivo. However, the DC did not give its consent and after 37 minutes Milazzo was forced to renounce the appointment. He became vice-president under Giuseppe Alessi. It would be a prelude for the years to come.
In October 1958, Milazzo formed an atypical coalition government that was supported by Communists, Monarchists, Neo-Fascists and dissident Christian Democrats, breaking the power monopoly of the DC, that had ruled Sicily since 1947. Despite the expulsion of Milazzo and his followers from the party, he continued to head the Sicilian regional government. The expelled members formed a new party, the Social Christian Sicilian Union (Unione Siciliana Cristiano Sociale, USCS), in December 1958. He competed in the regional elections in June 1959 under the slogan "Sicily for the Sicilians. Down with the mainland."
