“In the narratives of Herodotus”
The Medes and the Magus are mentioned as the two main powers and names of the first Achaemenid period. Although after the failure of their revolution, the Medes and the Mughals fought against Lydia and Greece in the army of Darius and his son Xerxes, some of the Medes continued to oppose the Persian and Achaemenid rule. Herodotus’ interpretations explain how the Magus made important efforts to restore the glory of the Median sovereign and the power of Astyages, the great king of Media. He also describes the role and influence of the Magus in the events and invasions of that time. Herodotus also describes how after the defeat of the Magus at the hands of Darius the Persian, the Magus helped Persian army in the conquest of the Greek islands and in most of the wars of Darius and his son Xerxes against the Western nations.
Herodotus therefore says: After Darius defeated the Magian revolutionaries, he imposed taxes on the peoples of the region. For example, from Babylon and Assyria (1000) thousand talents of silver and (500) young boys as slaves have been used. They also brought (450) talents from Hamadan and other parts of Media, including 10 regions.
Moreover, Darius expanded further, he went to Lydia, where the Magus asked for help against the Persians and two Lydian men asked him not to help Dara at all. Therefore, Darius sent 1,000,000 Persian cavalry as special guards against them in Lydia, in Ionia and Sardis areas. Additionally, after following victories in Babylon, he went to the Assyrians in Asia, who were powerful and had been famous since the time of the Medes. Darius was able to conquer them, who had long occupied Media and Upper Asia, and with the help of the Smerians held the Median emperor for 28 years.
Thus the Medes and Magoshemids, who had previously fought against the Achaemenid and whose revolution ended at the hands of Darius, were forced to fight against the Greeks as a fighting force with the army of Darius Xerxes. As mentioned in Herodotus; this displays the role, influence and importance of the Medes and the Mede Magus at that time. The Magus and the Medes played their role after the fall of the Median Empire in all periods such as the Achaemenid, Alexander, Seleucid and Ashkani periods. Later, until the Sassanid period, the Atesgadas had a position and reputation as advisors and close to the pasas, religious men and heads of the Zoroastrian religion.
