Poland is a mutant country, of East and West
I think that's how Poles view Poland too. That's why it makes most sense for us to call ourselves "Central", I guess.
I disagree, however, that we are borrowing only the worst from both West and East - that's a prejudiced notion :) We borrow the good, the bad and the ugly from both worlds :)))
The same counts for all Eastern European countries. The Czech Republic was long part of the HRE and than Austria-Hungary.
So, is the Czech Republic Central or Eastern European according to you (or the "experts")?
Hungary was long part of the former
What do you mean by "HRE"? Holy Roman Empire? If that's the case then Hungary was never part of HRE, because Holy Roman Empire never managed to conquer Hungary, as far as I understand.
Tacitus, as for RuSSia - the only people I've encountered who didn't consider RuSSia to be Europe were RuSSians themselves. RuSSia geographically is both in Europe and Asia. Mentally too, I think. This makes it similar to Poland in a way - a mutant country.
