The Tsar was *initially* only restored as a neutral moderator between various political forces, be them being "Fascistic" in the mold of French and Italian Fascism, to the Anglo-American Liberal Democratic, to the Orthodox Theocrats who grew popular during the trouble. Of course, Tsar Alexei's reforms ended up restoring much of the Monarch's power, but yeah, the real government power still lies in the office of Prime Minister, who is appointed through direct, Democratic election every seven years.
And don't cite the Spartacist Revolution in Germany, it only ended with Germany ceased as an unified polity, as Bavarian "Counter-revolution" restored the Wittelsbach Kingdom, the Prussians took over East Prussia and restored Wilhelm as "mere" King of Prussia, and the Central and North Communist States ended up as what is basically a warring rivals between Rosa-led Spartacists against Rohm-led Volkrepublik, even if both claimed to be legal government of *all* Germany until Bavarian, Prussian, Dutch, and Danes finally agreed to just carve up the failed states (with Prussians bailing out from united Germany project for good).
Communism permanently poisoned Germany, and no nation with such self-worth are willing to try it... Even the most ardent Leftist Republican nowadays leans more into French Fascism.
