If your fictional society is based on an actual, then it can t help showing similarities. But your readers might be unfamiliar with the world of the Medicis and the Borgias, so you might not have to worry about how similar your world is to it. If you are worried, I suggest that you gently stress a few differences.
You know what those differences are. Magical creatures were not around in Renaissance Italy (Well, we have no evidence they were there.) Modern weapons were not there. Maybe your characters were not Italians or French or whoever was there.
Even if you were writing a historical novel about Renaissance Italy, we know only through what they wrote what they thought. We don t know how they ate their salads, or what was in those salads, though we could make educated guesses. We re 21st century people.
We don t know how they lived without what we have, any more than we know how they used what they used everyday. We don t know how great the part religion played because our mindset on religion and God is different from theirs. I also suggest that you read books about creating fantasy worlds, and fiction that does contain fantasy worlds.
Note how the authors used what is familiar to us and what is not to created their societies. Read Thomas More s "Utopia." A fictional island, "created" by a scholar of the same time period as the Medicis and Borgias.
How did he make his world different from the England he knew?
You already have fictional societies on games on the internet. Try another category for your question.
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.
