PC = Plausibility Check
I was watching a documentary on the French Revolution. They mentioned that despite all the Jacobin insanity that took place in Paris, most of the country was fairly moderate. So I thought: what if Paris became some sort of city-state, separated from the rest of France, as a result of the revolution?
I figure this may have been somewhat unlikely, so I wanted to see what everyone else might think.
For a POD, I was thinking maybe before the death of Marat.
