I think history is interesting but find it hard to get in to nonfiction history books or lectures. Would relying on historical fiction to get my understanding of major historical stuff lead me to a very flawed understanding of what really happened? Consequently would that lead me to draw terribly flawed conclusions about what things mean when I compare current events to what I understand about history?
I'm a big fan of historical fiction, and I would say if it's helping you explore something you would not otherwise get into, then go for it!
With that said, a couple of things to keep in mind: First, historical fiction falls into a very broad spectrum that ranges from pure fiction set in a vaguely historic context all the way to almost academically rigorous history told via a character or context that did not happen to exist. Don't assume anything 'really happened' unless you've done some double-checking. Second, regardless of where a given book or author falls on the spectrum, remember that when you are reading fiction you're supposed to be entertained while you do it. The author made choices about content and style with the intend of you having a good time. Don't struggle to get through something because you want to learn more. Try another book instead.
Happy reading!
I am a big lover of historical fiction, as long as you're reading it with the knowledge that it's fiction and to be taken with a grain of salt. It usually can give you a general idea of a historical event or issue. Personally when I'm reading/watching historical fiction, I like to read up on the event or person that the story is about to know a little background info before getting into things.
