Answer:
To me, the greatest leader of Rome would have to be Julius Cesar
Step-by-step explanation:
Why? Because he's the one we all know from the history books and all of the old Rome stories about how great of a leader he was, how he had managed to set Rome into pretty much it's golden era and of course, how he was stabbed by his own people. Personally, I'd have to say good ol' JC is the greatest Roman leader.
