Megabazus was a highly regarded Persian general under Darius. Most information about him comes from The Histories by Herodotus. Troops left behind in Europe after a failed attempt to conquer the Scythians were put under the command of Megabazus. He was given a mission to conquer Thrace, in which he defeated several cities, including Perinthus and Paeonia. He then removed the Paeonians from their homeland and brought them to Darius in Sardis. Megabazus was suspicious of Histiaeus and advised Darius to bring him to Susa to keep a closer eye on him. His suspicions turned out to be true as Histiaeus provoked a revolt in the town he was formally in charge of and later sided with the Greeks against Persia. The successor to Megabazus's command was Otanes.
