> Empires usually last centuries, and get off to various shaky starts. I think there might be some confirmation bias here. A lot of the big ones we learn about in history lasted that long, but there were many that only lasted decades or a few generations at most. The Alexandrian Empire didn't outlast the death of Alexander, the Carolingian Empire didn't make the century mark, The golden horde only lasted a few generations, many of the early Mesopotamian empires came and went in decades, etc.
