Augustus was the first Emperor, leading a stable and peaceful Empire. He cut the size of the military and reorganized it so the Empire would have about 300,000 men under arms, basically manning the borders, and extremely mobile. He decided against expanding the Empire after the [[Battle of the Teutoberg Forest] in 9 B.C. and the loss the Romans incurred believing there was little to gain in spending great amounts of money and resources to conquer barbarians that could provide little in return. His successors agreed with his policies, although they did from time to time make small expansions to the borders. He undertook building projects and road construction that led to great improvements.
