no, quite literally, if cyrodiil had a democratic system of elections, presidential campaigns, vote ballots etc, what would they be called?
Well, when we abolished the monarchy, the leader was called "Lord Protector".
The British calling themselves an empire was just a bunch of Brits stroking thier epeens cause they can pwn noobs in teh Asias
And America, and Australia, and Africa. To be honest, when you rule over a third of the world, you have the right to call yourselves an empire. We didn't need to "stroke our epeens" when there was no one else who could defeat us.
