The Roman Empire managed to last over 1300 years. They weren’t what you or I would call a moral people. How do you explain their longevity?
And I don't get 1300 years.... Say you go with the earliest date after the Roman Republic.... when Julius Caesar became dictator (44 BC) to when Romulus Augustus abdicated... that's far short of 1300 years.
I could be wrong, because we didn't spend a lot of time on that in culinary school.
