Communist Russia Super Motherland - Another one that's kind of annoying. Russia after WWI must be Communist. There is no alternative. Certainly the White armies, if they had managed to organize, couldn't resist the MIGHTY SUPER DOOM ARMIES OF TROTSKY!
...Except that the Bolsheviks nearly bought it at Petrograd when the Whites surrounded them once...Only to fall apart because they couldn't agree on who was in charge.
(OK, maybe that's a little past 1900, but 1918 is close enough to the 19th century for me

)
Russia-stereotype - A bit related to the above, but it seems that if Russia isn't a brutal communist regime, it's a brutal monarchist regime. Full of drunkards. And they're all idiots. Because never in Russia was there a sober man who wrote plays or painted, and Russians certainly didn't invent anything useful, like, say, rebar. Or electric arc welding.
