As I understand it, the term "Middle Ages" actually refers to a different period to the term "Dark Ages". The "Ages" in Western Europe are I think normally seen like this... The Roman Empire - a period of complex well-ordered civilsation Dark Ages - originally considered as more barbaric times after the Romans left Middle Ages - societies had become more ordered, unified and Christian Renaissance - rediscovery of lost ancient knowledge, and growth of new ideas But the more people study the Dark Ages, the less "Dark" they seem! Anyway I guess tales of magic and mystery are often set in the Dark Ages precisely because that was a time in which you could imagine fantastic things like dragons lurking in the wilderness somewhere.
Hard to imagine such things could exist undiscovered in other periods of time. Plus they were times when Christianity co-existed with pagan religions, so Celtic and Norse myths were a big part of the culture too.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
