What Caused the Fall of the Roman Empire?

The roman empire was, was not a civilization. It was an empire. So it rose because of great men, men like scipio africanus and pompey. As the empire became larger and larger, the mode shifted from conquest to administration and bureaucracy. Now when an empire goes into bureaucratic mode, it becomes, well, it becomes less vigorous. And then how do you relayor relay orders to tor to the commander over there? These all big problems that they used to face. They were like kings in their own riot. That's what we need too push back again.
