Who, in your opinion, was the greatest of the Roman Emperors from 27BC to 1453AD? I will post a selection to choose from. Say who you chose, and why!
Personally I went for Constantine I, of all the Roman Emperors, he was the one who did most to shape the medieval and modern world, with his support of Christianity, and founding of Constantinople, ensuring the survival of the Roman state and Roman ideas post 476AD.
