Earlier today we saw a map that showed just how divided Germany remains, decades after the reunification at the end of the Cold War.
This is the percent of the vote pulled by the Democratic Socialists in Germany's recent election, via the DataIsBeautiful subreddit. You can see that this socialist party remains MASSIVELY more popular in the area that was the former East German.
That's all quite interesting and what not, but given that I know next to nothing about Poland doesn't covey much meaning.
That is, until you overlay this map of the old border of Imperial Germany and Imperial Russia over the map, as David G.D. Hecht did for the Big Think strange maps blog:
As one commenter noted, this divide essentially rides the boundary line of the ancient extent of the Kievan Rus.
And of course, the Scots are still voting differently than the English, hundreds of years after the Acts of Union 1707. You'll see a strong Lib Dem presence in Scotland, then a Labour presence at the border in the inset.
It's insane how these European countries are so petty that they can't drop the baggage of centuries-old civil wars and regional conflicts.
