Pretty sure Mussolini canonized the term in his work. You can just read Mein Kampf though too, which is very interesting and some of the ripest forbidden fruit out there. Reading it is like knowing that your parents hate your Uncle vehemently and keep talking about how terrible he was to them, then you go over there a couple decades later and get his side of story and it's like "Woah, they told me you went nuts and ran around pants-less while screaming and then kicked them out of the house but they didn't tell me about the part where they coated your toilet paper in bear mace and had you written out of grandpa's will."
