Alternatives to having a lazy Roman Empire clone?
(not in an alt hist way, original nations on an original landmass)
This is admittedly an annoying question to both ask and answer, but bear with me for a minute. I want to build a history of nations in my world (not for anyone to read im just having fun) but I am realizing that I have no idea how to start the cascade (by which i mean whatever circumstances made European history do all that) with anything other than a roman empire analogue randomly popping in and conquering half a subcontinent, which I'd simply prefer not to do. No objective reason, I just dislike the idea of having a roman empire!
I think this is all the context necessary for what I'm trying to do, assume I'm going for some original spin on the medieval fantasy nations template. Also assume I have no clue about how any other places worked even though that's not entirely true.
