Later in life, although he was not an official card-carrying member of the National Fascist Party, Bombacci tried to help Mussolini legitimize the Italian Social Republic and relegitimize Italian Fascism after Mussolini was ousted as Prime Minister of the Kingdom of Italy.[6] He was the author of the economic theory of fascist socialization for the 1943 Congress of Verona. Nicknamed “the Red Pope” by the bourgeoisie, Bombacci told a crowd in Genoa in 1945 that “Stalin will never make socialism; rather Mussolini will.”[7]
