Absolutism faded in europe with development, as concessions were needed in view of growing middle class social power. But not long after, the middle classes in SOME european countries gave up on constitutionalism and turned to fascism, as a protection against left revolution. Now that wasnt quite the same as absolutism, because fascism involved mass mobilization, while IN THEORY absolutism didnt allow for that. And the actual fascist takeovers were either republics like Germany, or constitutional monarchies like Italy, where the king exerted little authority over the fascist state. (I dont know much about Romania in this period)
But is it possible to have a more or less direct jump from absolutist monarchy to fascism, with the monarchy remaining institutionally dominant, even if theres also a mass mobilzation movement in support.
I think so. The most likely possibility is Russia. Where the antisemitic, panslavic, Black Hundreds acted as a mass mobilization, fascist style movement, but in support of the institutional power of the monarchy.
Now even here it isnt quite direct, as Russia has a duma, albeit with limited power, in the years up to WW1.
Lets say Russia manages to avoid the Feb Revolution (the usual - no Rasputin, better luck at Tannenberg, smarter generals, less pressure from the west for offensives, Gallipoli goes better, whatever) and Germany loses, as per OTL, but this time the revolution wins in Germany - whether its called communist or not - Liebknecht and Luxembourg take power. The Tsar, using the fear of red revolution coming out of Germany, abolishes the duma, and uses the black hundreds, greatly expanded, to suppress opposition. Meanwhile Russia resumes the economic expansion/industrialization that began in the years before WW1.
Will the upper middle classes, frightened by whats happening in Germany, really defend constitutionalism? Look at their reactions in OTL in the months before the November rev. OTOH, will the black hundreds, insist on power in their own right, or be willing to be ballast for renewed tsarist absolutism?
