These 3 questions will help you determine the Greatest Roman figure: Who is the most prominent Roman leader? Which single person did the most to make Rome the most powerful Empire ever known? When you think of Rome which leader first comes to mind?
I think without a doubt Julius Caesar is the greatest. I think he was the greatest general, I put him ahead of Trajan as a general. He significantly expanded the empire outside of Italy which finally allowed Rome to become a dominant superpower, he also was the most skilled politician with his new ideas and I think his assasination actually speeded up the process of Rome becoming a great empire, Rome might have remained a republic for much longer. One of his best decisions was to select Octavian as his heir, people forget as great as Augustus was, he would never have been an emperor had Julius decided to choose someone else to be his heir.
