Do you have sources for any of these claims? It's not even the question of political motivation, I've never seen such claims made even by Finnish sources.
Sure. In fact, I've seen the number referenced repeatedly. Now, as I said, I am not ruling out that every time it's mentioned it's based on the same false information/assumption, but in general, the estimation of a lot more displaced Finnic people ending up in Finland than the Russion census figure can account for doesn't strike me as nonsense. As also said, I'm more than willing to grant some leeway there, but the numbers from other areas of origin for these migrants are clear. At which point my question becomes: if they didn't come from Eastern Karelia, then where
did they come from? Which ties into:
And I haven't seen it claimed anywhere that half a million Karelians fled from Russia to Finland during or after the war.
The claim is more that there were circa one million Finnic people from the USSR who ended up displaced into Finland. The numbers for other Finnic regions have been determined mostly beyond dispute. Which leaves about 500,000... and I just can't think of any place other than Karelia they could have come from. If there is some other pocket of Finnic peoples in the pre-war USSR that ended up being emptied into Finland due to persecution or something, that can play a role here-- but I'm not aware of any such thing.
Anyway.
Russian Karelia in Search of a New Role (1994), a rather conciliatory work edited by Heikki Eskelinen (which explicitly rejects modern-day irridentism) cites an estimated million ultimately displaced people arriving in Finland from Russia between the East Karelian uprising of 1921 and the aftermath of World War II. This is based on census information from the Finnish government, which—speaking no Finnish—I cannot read in depth. Perhaps worthy of note is that Eskelinen and his co-editors refer to 420.000 displaced people from the USSR-annexed parts of Finnish Karelia, rather than 410.000, which is a number I have more commonly seen. Likewise, they estimate 60,000 or so displaced migrants from Ingria, rather than the 50,000 also cited elsewhere. That would be 20.000 who wouldn't have to come from Eastern Karelia, I suppose— although I cannot judge whether Eskelinen and his co-editors are better-informed or worse-informed than others.
Borders and Border Politics in a Globalizing World (2004), edited by David E. Lorey, cites one million as the total number of displaced Finnic people from the USSR who ended up in Finland as well.
Victims and Survivors of Karelia (2011), edited by Sari Autio-Sarasmo and others, and published in the Journal of Finnish Studies, likewise cites this number. (The work is actually about Finnish-Americans who migrated to Soviet Karelia when Stalin made false promises, and relates how the thing ended in disaster, but the fact that Karelia was underpopulated due to the mass exodus of Finnic inhabitants to Finland is expounded on to explain the Soviet motivations for the whole mad scheme.)
...those are just a few works. I can probably keep up listing till I'm blue in the face. That doesn't mean, incidentally, that the claim
has to be taken at face value. As I said: Finland, too, has (or at least had) a stake in making pre-war Karelia seem to be as Finnic as possible— just as Russia had a stake in representing the area as being as Russian as possible. My point is that considering what we know, the Finnish claims are more believable than the Russian ones. I'm not sure about the Tsarist census, but the USSR ones are notorious for being political documents. For instance, it's well known that about 1,5 million Russians were just invented on the spot when population figures didn't meet growth expectations in the 1939 census. When it's Finnish census claims versus Soviet ones, I'll be more inclined to believe the Finnish ones until compelling evidence to the contrary is presented. Simply because the USSR is
known to have cooked the books when the census didn't fit the political narrative, while Finland isn't know for that at all.
They're completely incompatible with the population of Eastern Karelia. Eastern Karelia had a total population of
about 270 thousand in 1926, of which certainly not all were Karelians. The population increased to 470 thousand by 1939 but this was largely due to large scale Russian immigration. So unless Russia was hiding another 250 to 350 thousand Karelians somewhere, these numbers don't add up. Furthermore, the vast majority of the population in Eastern Karelia was evacuated during WWII, leaving just about 36 thousand Karelians,
according to Finnish sources. So how could half a million escape to Finland?
In my view, the best explanation remains that pre-war Russian census figures undercount Karelians in the region (and quite possibly overcount Russians, by registering Karelians or anyone of uncertain origin as Russians).
It's true that the vast majority of the population was evacuated during WWII, leaving behind some 85,000 inhabitants, of whom just under half (c. 42,000 -- not 36,000) were Finnic. (Source:
Finland in the Second World War: between Germany and Russia (2002), by Olli Vehviläinen) A major problem is that no actual new census was published in the USSR until 1959. By then, the displacement had all happened. The 1959 census may, as far as I'm aware, be considered accurate. It lists 85,473 ethnic Karelians in Eastern Karelia, and 81,827 elsewhere in the USSR. (There were Karelians elsewhere before the war, too, and these were not displaced: that population does not consist of displaced people from Eastern Karelia.) So that's the post-war situation, and I think we can take that as a given.
The Soviet line is that most Karelians removed from Eastern Karelia returned after the war, and that a small number moved to Finland. (Based on the Soviet figures, that number would be about 23,000 or so.) I think it's far more likely that the pre-war number of Karelians was simply a lot higher than the pre-war Soviet numbers indicate. As I said, I'm more than willing to treat the number of 'one million in total' as a nicely rounded-up figure, but that estimate leaves about 500,000 displaced people moving into Finland from the USSR who had to come from
somewhere. Even if the claim of one million is inflated, the difference between c. 23,000 and 500,000 is just
huge. Even if the 'one million' cited by Finnish sources is an inflated number based in myth-making and the inherent attractiveness of a nice rounded-up number, I just can't imagine them blithely turning (460.000+23,000=) c. 483.000 into one million.
Known-to-have-been-manipulated pre-war Soviet census figures being wrong just seems like the more plausible explanation for the larger part of the discrepancy. I'm not discounting the possibility that the 'one million' figure is a myth that got to lead its own life. Yet even if that's the case, and even if that whole migration occurred in waves between '21 and '45, it still seems pretty clear to me that a
lot more Karelians ended up moving to Finland than should have been able to given pre-war Soviet figures.
On the other hand, this idea--
One answer is that the Finnish military and its auxiliaries (like the Lotta Svärd) are included in the reckoning - if we put together every civilian and soldier who had to leave Karelia for the 1940 borders in 1944, we would get pretty close to million, I guess. But then the great majority of these people would not be East Karelians, but people who prewar lived within the 1920 borders.
--doesn't strike me as a very strange explanation, which might go a long way to explaining certain possibly conflated numbers. It's a hypothesis, but it's worth considering as a possible factor, and I frankly admit I hadn't done so yet.
It's also possible that
both explanations for the discrepancy are true at the same time: pre-war Russian figures undercounted Karelians, and post-war Finnish figures overcounted (by counting basically everyone coming into Finland from the area).
