/lit/ - Literature

I have a question on genre:

I've written a novel which, being set in a made up world and using a medieval-tier tech, always made me think it's fantasy.

But there's no magic, or fantasy races. Beta readers have called it literary, and I've been told historical fantasy (like Guy Gavrial Kay) is close, but I'm not sure on that.

It reads like historical fiction (which is what I mostly read), but deals with literary concepts. It certainly doesn't match any fantasy I've ever read (or heard of), so how do I classify this thing?

Tl;dr is it automatically fantasy if its set in a world you made up?
