Who was the greatest Roman Emperor? Why?

Augustus Caesar

Explanation:

Augustus’ enormous personal power, won though bloody struggle, meant he had no rivals. The 200-year Pax Romana began.

Augustus conquered Egypt and Dalmatia and its northern neighbors. The Empire grew south and east in Africa; north and east into Germania and south-west in Spain. Buffer states and diplomacy kept the frontiers safe.

An overhauled tax system paid for his new standing army and Praetorian Guard. Couriers carried official news quickly along his roads. Rome was transformed with new buildings, a police force, fire brigade and proper local administrators. He was generous to the people, paying vast sums to citizens and veterans, for whom he bought land to retire on.
