radical Italian politician and Fascist ras, or local party boss, who helped Benito Mussolini rise to power in 1922 and who became an important figure in the Fascist regime.

After dropping out of school to work for the railroad in Cremona (1909), Farinacci became an ardent Socialist. When World War I broke out, he advocated Italian intervention, and after the war he became attracted to Mussolini. Farinacci founded the Fascist daily Cremona nuova and was the main party organizer in Cremona. Under Farinacci, the Fascist squadre d'azione (armed squads) engaged in brutal repression and violence, often incurring Mussolini's disfavour, especially by forcibly taking over Cremona (July 1922).

Farinacci, continually critical of Mussolini for being too cautious and moderate, had many followers and probably hastened the Fascist ascendancy. Appointed secretary general of the party (February 1925), Farinacci insisted upon defying Mussolini and was allowed to resign in March 1926.

Farinacci practiced law until he was recalled to power in 1935. He became Mussolini's main contact with the Germans and urged Italy's entry into World War II, which proved disastrous. When Mussolini was overthrown (July 1943), Farinacci, protected by the Germans, escaped arrest. He returned to Cremona but tried to flee Italy when the Allies advanced northward. Recognized by Italian partisans, he was tried and executed by a firing squad.
