Historical writings need a lot of research to make sure they’re correct. It isn’t just about the events of history – it’s the little things that make that period unique.
Certain things will put you directly into a time period, and others will pull you out. When do you think of when you think pillbox hat?
Beyond that, there are the words used. We can’t all be like Heinlein and make up words like ‘grok.’
I haven’t written historical pieces. In some ways, I find them overwhelming. When they’re done well, they’re beautiful. I know some writers who do it very well. I feel like I’m learning when I listen to the writers I know who do historical pieces.
Perhaps one day… but not today.
