That's what I wrote in my first comment: "The Manifesto della cucina Futurista was written in 1931, but it was, overall, forgettable: much more relevant for art and politics were the pre-WWI manifestos." So, yes, Manifesti were produced after 1919, but overall there were of low impact, the driving force of the futurist movement had been exhausted with the end of WWI. Similarly, D'Annunzio political and artistic contribution ended with the occupation of Fiume (I greatly recommend reading "La quinta Stagione" by Léon Kochnitzky or "Le mie stagioni" by Giovanni Comisso for entertaining accounts of the occupation of Fiume). After all, Marinetti had to do something with his life, and what he chose to do was writing increasingly irrelevant stuff. Fascism just used certain aspects of the message of the Futurists, and the most violent in particular. Mussolini was a pragmatic man, and he used what he needed when he needed it, without particular ideological concerns. For example, he first supported with money and press D'Annunzio and the Occupation of Fiume, but he quickly backpedaled when he understood that the wind was changing direction (many Futurists participated in the Occupation of Fiume). Futurism had as one the main aspect of their message the destruction of museums, all that was ancient and dusty had to be abandoned; Fascism, on the other hand, was looking at the Roman Empire and the classical world as inspiration and motivation for a great, new Italian empire of sort. I could not find more opposite messages. As for the comment, "Also, if the party was founded in 1919, surely there must have been fascist-leaning writing in the years leading up to that. Political parties don't just spontaneously appear." I disagree. Sure, there are not infinite political orientations that can be proposed, but fascism did not exist either as a word or a movement or a structure idea or message before 1915-1919, and if we group all right-wing, or authoritarian, or "violent" groups as fascists, we are not having an insightful conversation. There are many right-wing movements that are not fascist. Unfortunately, fascist and fascism have become terms of reference for authoritarian or right-wing or nationalist movements.
