Yeah, it does. That's how the writers generally portray it. It doesn't mean it's "my civilization". I'm just saying. You can bring up the usual social-political stuff from the real world when it comes to "empires", but I'm talking about video game lore. Not earth history.
Neither was I. I said "your civilization" to refer to the fact that you used the word to describe the empire.
And from what I can tell, it's lowest points was when there was a lack of a legitimate dragonborn. Otherwise, it's painted in a good light.
I think probably the people who died in the wars for its founding would say those were low points. There's a reason Black Marsh and Elsweyr took their first opportunity to leave a weakened empire behind.
This goes without mentioning that the empire in TES is more about religion than politics. From it's start, it's two main ideals was Incorporating both human and elven religions to create what we know as the 9 divines. Syncretism and compromise. A hallmark of any civilized people. And warding off daedra and their worshippers. Much war can be created from all of these religious differences, but it doesn't mean they're uncivilized.
I don't agree that syncretism has anything to do with civilization. The term civilization is loaded anyway. It usually means "mine is better than yours" whether it actually is or not, and "that gives me the right to force it on you." Regardless, it doesn't tell me why I should care whether Cyrodiil rules over Skyrim or not. Contrary to what imperials say, the Nords don't need their rule.
