I detest the 'empires typically last 250 years' factoid because it's straight up made up. there is no historical precedent for this, it's pure, unfettered cope.
I'm not even sure how you'd judge that. Likr does every dynasty of countries like China and Persia count as an "empire"? And do Rome and Byzantium count separately?
Let me just look that last one up, guessing it’s a simple settled yes/no.
