Well, it's less of a "legitimate" political ideology and more of an alternate ideology for this timeline. When it comes to timelines on this site, it's not exactly as strange of a concept as you might think, as evidenced by the many alternate ideologies listed in
this post by
@Born in the USSA (which will hopefully include a number of ones written by yours truly at some point in the future). There are of course, two prime issues when it comes to creating alternate ideologies such as Carnarism, Petrosianism, and the Volkssturmbewegung. I think this summary of those issues by former member (read: banned member) Dr. Strangeglove is a perfect one.
Now, with that in mind, what I'm trying to do in OPAS (which is, in my opinion, something that a decent amount of alternate history
doesn't do, though I could be wrong in this regard) is come up with plausible alternate ideologies that are based on the OTL beliefs of the individuals involved in the creation of said ideologies. Petrosianism is an exception to this rule, mainly because Kamo's own political views were essentially non-existent, given the fact that he didn't have the inclination for forming his own views on socialism/communism in OTL. When it comes to Carnarism, the second issue comes into play a lot, seeing as how (much like Dr. Strangeglove's *Trotskyism) aspects of Carnarism come pretty damn close to my own views and beliefs. A Carnarist world might come close to an ideal world for me, but because it's ideal, I'm aware that it could never work in OTL. Carnarism is like Fiume, a semi-utopian dream forged from the mad vision of an artistic superman, one that was ultimately destined to fall to the wayside as history continued its inexorable march forward. That being said, I could just be a pretentious hack waxing philosophically about bullshit, who knows?
ANYWAY.
Enough of this tangent where I ramble about my own personal bullshit, and let me answer your question about Carnarism and its inspirations. As you noted, the
Charter of Carnaro is one of the inspirations for the Carnarists and the Charter of Rome (what the founding document of Carnarism is called). Now, when it comes to other manifestos and political theories that I'm (and by extension, the Carnarists are) drawing on for inspiration, the main ones (as of this post) are Filippo Tommaso Marinetti's
Futurist Manifesto and the
Manifesto of the Italian Futurist Political Party, Valentine de Saint-Point's
Manifesto of the Futurist Woman and the
Futurist Manifesto of Lust (for some of the more gender and sexually progressive elements with the second work), and finally Enrico Corradini's theory of
Proletarian Nationalism. Additionally, there
might be some influences from the Roman Republic, specifically the concept of
Latin Rights for conquered peoples (though I'm not quite sure how or even if I'm going to incorporate that, hence the might). Unsurprisingly, you'll notice that several different "views" of what
exactly constitutes Carnarism as an ideology. Some will adhere to the Futurist beliefs of Marinetti, others will embrace Corradini's proletarian nationalism, there'll even be followers of the more conservative elements of Carnarism, and finally there will be those who believe in Carnarism as laid out in the Charter itself without making any sort of distinction between the various views. Generally-speaking, that last one will be the most prominent among the Italian citizenry, because it's the most uniform and the least divisive of the views.
That's the key difference between OPAS' Carnarist Italy and OTL's Fascist Italy, in my opinion. While the governments of both states feature shades of authoritarianism, the latter is far more controlling and restrictive in its views of the individual, while the former possesses a more radical view of the individual, one that's more closely related to the Nietzschean version of the
New Man. They are both
ideocracies, but while Fascist Italy is a
totalitarian one (where citizens are forced to follow the state ideology), Carnarist Italy is a
populist one (where citizens voluntarily follow the state ideology). Naturally, these both lead to the development of a sort of authoritarian personality/mindset within their citizens, but the Carnarist citizen is convinced that Italy is great because it is truly
free. Those enemies of the Italian state aren't enemies because they're scapegoats for their own insecurities and doubts that they must fight within themselves, they're enemies because they're shackled to outdated views of humanity and morality.
To the Carnarist, the communist claims to fight for the people, yet refuses to let the people be free to pursue their dreams. The capitalist claims to offer the people the freedom of choice, yet robber barons and businessmen can accumulate vast amounts of wealth while the poor suffer. The concept of the New Man is ingrained within Carnarist thought, and that plays an additional role in who the Italians invite to join the League of Fiume as either equal member states or as lesser League-aligned nations. Volkssturmbewegung Germany takes inspiration from Nietzsche as well as some influence from Carnarism, therefore they're a natural ally as an equal member state. Similarly,
Legionary Romania (minor spoilers there) has an ideology based around the creation of a revolutionary New Man (albeit one that's different in conception and of a spiritual rather than a moral nature) and share the same Latin heritage as Italy and are thus worthy to be viewed as an equal member state, despite their
atrocious Anti-Semitic, Anti-Ziganist, and Anti-Magyar beliefs. On the other hand,
Garveyist Liberia (more minor spoilers) is a lesser member state because while they share some similarities with the Carnarists (in fact, they receive support from the Carnarists later on) and have similar goals in working toward dismantling the plutocratic colonial system, they also differ a tad too much with their beliefs in racial purity and separatism ("Why would you seek to separate and purify the races when they can all strive to be noble and superhuman?"), Pan-Africanism ("Come now, every race has its own distinct culture to be celebrated!"), and economics ("Corporatism is the future, Capitalism is the past!").
Of course, all of this isn't meant to say that Carnarism is this super wholesome nationalist ideology that everyone should follow, because it's not. While their colonial policy is
leagues (pun intended) better than OTL's Fascist policy and native culture is celebrated and accepted, Italian is the first thing that's taught in schools, followed by the teachings of native dialects and tongues, although the actual instruction will be done in the native language. Plus, this doesn't even cover how they wage war and the lengths they'll go to achieve victory (hint, it's bloody and glorious and superhuman). Carnarism is a rush to the future and it has no time for those who aren't willing to go along with that rush. The old world order will fall and the Carnarist future will dawn.
