Mitrobates
Mitrobates was an Achaemenid satrap of Daskyleion under the reigns of Cyrus the Great, by whom he was nominated, and Cambyses. After Cambyses died, and during the struggles for succession that followed, he is said to have been assassinated, together with his son Cranaspes, by the neighbouring satrap of Lydia, Oroetes, who had expansionist views on Anatolian territory. After that, Oroetes added the territory of Hellespontine Phrygia to his own territory of Lydia.
These events took place in the troubled times of the interregnum between Cambyses and Darius I, with the usurpation of Gaumata, whom Herodotus refers to as "the Magians". The story of early satraps of Asia Minor, including Mitrobates, was related by Herodotus.
Mitrobates is the first known Persian satrap of Daskyleion. Following the reorganization of Darius I, he was succeeded by Megabazus and then his son Oebares II and Artabazus, who established the Persian Pharnacid dynasty, which would rule Hellespontine Phrygia until the conquests of Alexander the Great.
