Who is Augustus from The Twelve Caesars and what is their importance?

Augustus is one of the most beloved emperors and the head of the family for almost the rest of the Caesars after him. Everything he does is to avenge Julius Caesar and bring great honor to the empire. He works a bit differently, however. He is more professional towards the army, rather than affectionate as Julius Caesar had been. He greatly cares about the morals of the soldiers and punishes them for any and every moral offense. He is also very concerned with his own image and that of his family.
