Certain exiled citizens of Naxos came to Miletus to seek refuge. They asked Aristagoras to supply them with troops, so that they could regain control of their homeland. Aristagoras considered that if he was able to supply troops to the Naxians, then he could become ruler of Naxos. So he agreed to assist the Naxians. He explained that he did not have enough troops of his own, but that Artaphernes, Darius’ brother and the Persian satrap of Lydia, who commanded a large army and navy on the coast of Asia, could help supply troops. The Naxians agreed to Aristagoras seeking Artaphernes' support and supplied him with money.
