The siege of Naxos (499 BC) was a failed attempt by the Milesian tyrant Aristagoras, operating with support from, and in the name of the Persian Empire of Darius the Great, to conquer the island of Naxos. It was the opening act of the Greco-Persian Wars, which would ultimately last for 50 years. Aristagoras had been approached by exiled Naxian aristocrats, who were seeking to return to their island. Seeing an opportunity to bolster his position in Miletus, Aristagoras sought the help of his overlord, the Persian king Darius the Great, and the local satrap, Artaphernes to conquer Naxos. Consenting to the expedition, the Persians assembled a force of 200 triremes under the command of Megabates. The expedition quickly descended into a debacle. Aristagoras and Megabates quarreled on the journey to Naxos, and someone (possibly Megabates) informed the Naxians of the imminent arrival of the force. When they arrived, the Persians and Ionians were thus faced with a city well prepared to undergo siege. The expeditionary force duly settled down to besiege the defenders, but after four months without success, ran out of money and were forced to return to Asia Minor. In the aftermath of this disastrous expedition, and sensing his imminent removal as tyrant, Aristagoras chose to incite the whole of Ionia into rebellion against Darius the Great. The revolt then spread to Caria and Cyprus. Three years of Persian campaigning across Asia Minor followed, with no decisive effect, before the Persians regrouped and made straight for the epicentre of the rebellion at Miletus. At the Battle of Lade, the Persians decisively defeated the Ionian fleet and effectively ended the rebellion. Although Asia Minor had been brought back into the Persian fold, Darius vowed to punish Athens and Eretria, who had supported the revolt. In 492 BC therefore the first Persian invasion of Greece would begin as a consequence of the failed attack on Naxos, and the Ionian Revolt. Background In the Greek Dark Ages that followed the collapse of the Mycenaean civilization, significant numbers of Greeks had emigrated to Asia Minor and settled there. These settlers were from three tribal groups: the Aeolians, Dorians and Ionians. The Ionians had settled about the coasts of Lydia and Caria, founding the twelve cities which made up Ionia. These cities were Miletus, Myus and Priene in Caria; Ephesus, Colophon, Lebedos, Teos, Clazomenae, Phocaea and Erythrae in Lydia; and the islands
