Darius had two most important tasks when he ascended the throne of Achaemenid Empire. He had to conquer the rebellious areas and to integrate them into a systematic empire. The empire is notable for its successful Centralized, Bureaucratic administration. Darius, however, ruled the empire with the help of his provincial Governors who overlooked the territory.
