I don't wanna sound confrontational, but could you post some population figures for the period? I'm very curious to know what Russian sources say, especially since the book I have- McEvedy and Jones'
Atlas of World Population History- I know to be super inaccurate in a few places, and I expect Eastern Europe is one, since it was written during the Cold War, when access to Eastern European historians and archaeology and so on wasn't so easy.
that said, here are its figures:
Which I plugged into a table of it vs a few other places in game:
Sorry if it's a little confusing- pop 1 is from 1500, pop 2 is from 1800.
If the figures in that book are accurate- and I know that's a big if, and I'm very interested in the take on them from the Eastern Europe experts in this thread- but if they are, then Eastern Europe is actually one of the most developed and province-rich parts of the map, with both development and provinces relative to its population ahead of both Iberia
and France. In fact, in 1500 France has more people in it than Muscovy, the Baltics and Ruthenia combined, at 15 million vs 12 million. Even in 1800 it's pretty close. (Again, if the figures are accurate for Eastern Europe).
Population isn't the only criteria for development and provinces- from my understanding balance is a bigger one, and I agree that Eastern Europe could well need more development so they can hold against the Ottomans better. But at least according to these figures, "the desert of Eastern Europe" you keep talking about is pretty false...
