I've never read anything particularly interesting about Eastern Europe. As far as I'm concenred the only reason Eastern Europe is underrepresented and Western Europe is overrepresented is because Western Europe and Russia have had a long history of power and Eastern Europe has had a long history of nothing except existing, getting conquered, etc.
a) Then you need to go find yourself a book of European history and see how important the area was.
b) Eastern Europe has had a long history of nothing except existing, getting conquered, etc? Oh really? Byzantium was the most advanced and civilized nation of Europe of its time, Bulgaria had one of the biggest countries in Europe (second), Serbia at its highest point controlled most of the Balkans, Poland had all the territory from Germany to Ukraine for some time, Hungary was a huge military power in its time, bigger than the Western countries. Additionally, Byzantium lasted
1000 years longer than the western Roman Empire, Hungary, Poland and Romania stopped the Turks countless times from advancing into Europe, do I really need to say more? If Eastern Europe would have been no man's land, Western Europe would be an Arabo-Ottoman State right now, and not the British but the Chinese and the Arabs would have colonized the world, and we would be talking in either Turkish, Mongolian, Chinese or Arabic.
Poland is one of the oldest places in the world. Poland began 4000 years ago when there were Polish Slav tribes inhabiting the area of the Vistula river.
Oh come on. Pure exaggeration. I can go even further: the oldest human* bone in Europe and third oldest in the world was found here. SO WHAT?
Edit: Of course, I mean Homo Sapiens Sapiens, the kind of humans that we are, not Neanderthals or something like that.
