Megabates

Megabates (Greek: Μεγαβάτης) was a Persian military leader in the late 6th and early 5th centuries BC. According to Herodotus he was a cousin of Darius the Great and his brother Artaphernes, satrap of Lydia. Based the writings of Herodotus, Megabates is most notable for his joint participation in the failed 499 BC siege of Naxos. With Aristagoras and 200 ships, he was sent by Darius the Great to annex the small Aegean Sea island to the Persian Empire.

Herodotus is of the view that this venture failed after a siege of four months because of the mutual dislike between Aristagoras and Megabates. As a result, Herodotus states that it was Megabates who forewarned the Naxians of the ensuing Persian siege, as he and Aristagoras argued after Megabates punished a captain for not setting up a watch. As a result, Naxos gathered supplies and fortified their city to withstand the four-month-long siege. It is believed that Megabates' rationale was to shame Aristagoras in the Persian court, for they were earlier during the sail involved in a dispute.

Megabates followed in his older brother's footsteps and was appointed satrap of Phrygia, with his residence at Dascylium.
