I dunno the numbers....the german borders have been always very fluid! :)
I have checked he numbers for you. It is about 25%. The reason I asked is simple. To compare losses.
Poland lost to Soviets about 48% of pre-war territory. Numbers are important - now we can talk rather than chat about all issues. :)
in large numbers till 1939 out of country?
Not really. Most of the migration happened between 1870 - 1914. Then after 1945. There is no 11 millions Polish in the USA. Those are people with Polish ancestors that somewhat are aware of t he fact. Anyway what that has to do with anything?
Emigration, immigration those are separate issues. We are talking about serfs who risked their limbs and oft lives to ESCAPE, then cross the border in hope of becoming serfs but in Poland. Do I need it spell it for you in a big letters?
Being a serf in Poland was so attractive to serfs in Russia that they took a big risks to go for it. Meaning being a serf suck but being a serf in Russia suck big time times 100.
By the way what about compensation to Poland form Russia for all that s..t? You have plenty of gold mines time to pay up!
