Some of the themes with a lot of the Dystopian/Post Apocalyptic books and films involve the world after some kind of major disaster, war, disease, or some combination of the three. But most of these stories take place in the future and I'm tinkering with the idea of a kind of alternate 2014 where the Big Event happened in the early 1800's. So far for ideas I have a major plague that wipes out most of the world's population, causing panic and war until enough people develop an immunity against it to slowly rebuild society. A few major natural disasters come to mind like a Super Volcano, or something devastating enough to temporarily knock humanity back into the Dark Ages but still leave them mostly intact enough to recover. Any thoughts or suggestions?
