What was the political legacy of the achaemenid empire? -short answer is fine : )

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. Therefore he connected these regional government to the center with the help of the postal system. The success of this empire lies in the fact that the ruler had the ability to recognize and utilize the already established governments. Therefore it can be said that the Administrative system of the Achaemenid was based on the previously existed Akkhadian, Assyrian and Egyptian system of administration.
