The Ionian Revolt, and associated revolts in Aeolis, Doris, Cyprus and Caria, were military rebellions by several Greek regions of Asia Minor against Persian rule, lasting from 499 BC to 493 BC. At the heart of the rebellion was the dissatisfaction of the Greek cities of Asia Minor with the tyrants appointed by Persia to rule them, along with the individual actions of two Milesian tyrants, Histiaeus and Aristagoras. The cities of Ionia had been conquered by Persia around 540 BC, and thereafter were ruled by native tyrants, nominated by the Persian satrap in Sardis. In 499 BC, the tyrant of Miletus, Aristagoras, launched a joint expedition with the Persian satrap Artaphernes to conquer Naxos, in an attempt to bolster his position. The mission was a debacle, and sensing his imminent removal as tyrant, Aristagoras chose to incite the whole of Ionia into rebellion against the Persian king Darius the Great.
In 498 BC, supported by troops from Athens and Eretria, the Ionians marched on, captured, and burnt Sardis. However, on their return journey to Ionia, they were followed by Persian troops, and decisively beaten at the Battle of Ephesus. This campaign was the only offensive action by the Ionians, who subsequently went on the defensive. The Persians responded in 497 BC with a three-pronged attack aimed at recapturing the outlying areas of the rebellion, but the spread of the revolt to Caria meant that the largest army, under Daurises, relocated there. While initially campaigning successfully in Caria, this army was annihilated in an ambush at the Battle of Pedasus. This battle had started a stalemate for the rest of 496 BC and 495 BC.
By 494 BC the Persian army and navy had regrouped, and they made straight for the epicentre of the rebellion at Miletus. The Ionian fleet sought to defend Miletus by sea, but was decisively beaten at the Battle of Lade, after the defection of the Samians. Miletus was then besieged, captured, and its population was brought under Persian rule. This double defeat effectively ended the revolt, and the Carians surrendered to the Persians as a result. The Persians spent 493 BC reducing the cities along the west coast that still held out against them, before finally imposing a peace settlement on Ionia which was generally considered to be both just and fair.
The Ionian Revolt constituted the first major conflict between Greece and the Persian Empire, and as such represents the first phase of the Greco-Persian Wars. Although Asia Minor had been brought back into the Persian fold, Darius vowed to punish Athens and Eretria for their support of the revolt. Moreover, seeing that the myriad city states of Greece posed a continued threat to the stability of his Empire, according to Herodotus, Darius decided to conquer the whole of Greece. In 492 BC, the first Persian invasion of Greece, the next phase of the Greco-Persian Wars, began as a direct consequence of the Ionian Revolt.
Background
In the 12th century BC, the Mycenaean civilization fell as part of the Late Bronze Age collapse. During the subsequent dark age, significant numbers of Greeks emigrated to Asia Minor and settled there. These settlers were from three tribal groups: the Aeolians, Dorians and Ionians. The Ionians had settled along the coasts of Lydia and Caria, founding the twelve cities which made up Ionia. These cities (part of the Ionian League) were Miletus, Myus and Priene in Caria; Ephesus, Colophon, Lebedos, Teos, Clazomenae, Phocaea and Erythrae in Lydia; and the islands of Samos and Chios. Although the Ionian cities were independent from each other, they acknowledged their shared heritage, and had a common temple and meeting place, the Panionion. They thus formed a 'cultural league', to which they would admit no other cities, or even other tribal Ionians. The cities of Ionia had remained independent until they were conquered by the famous Lydian king Croesus, in around 560 BC. The Ionian cities then remained under Lydian rule until Lydia was in turn conquered by the nascent Achaemenid Empire of Cyrus the Great.
While fighting the Lydians, Cyrus had sent messages to the Ionians asking them to revolt against Lydian rule, which the Ionians had refused to do. After Cyrus completed the conquest of Lydia, the Ionian cities now offered to be his subjects under the same terms as they had been subjects of Croesus. Cyrus refused, citing the Ionians' unwillingness to help him previously. The Ionians thus prepared to defend themselves, and Cyrus sent the Median general Harpagus to conquer Ionia. He first attacked Phocaea; the Phocaeans decided to entirely abandon their city and sail into exile in Sicily, rather than become Persian subjects (although many subsequently returned). Some Teians also chose to emigrate when Harpagus attacked Teos, but the rest of the Ionians remained, and were in turn conquered.
The Persians found the Ionians difficult to rule. Elsewhere in the empire, Cyrus was able to identify elite native groups to help him rule his new subjects – such as the priesthood of Judea. No such group existed in Greek cities at this time; while there was usually an aristocracy, this was inevitably divided into feuding factions. The Persians thus settled for sponsoring a tyrant in each Ionian city, even though this drew them into the Ionians' internal conflicts. Furthermore, a tyrant might develop an independent streak, and have to be replaced. The tyrants themselves faced a difficult task; they had to deflect the worst of their fellow citizens' hatred, while staying in the favour of the Persians.
About 40 years after the Persian conquest of Ionia, and in the reign of the fourth Persian king, Darius the Great, the stand-in Milesian tyrant Aristagoras found himself in this familiar predicament. Aristagoras's uncle Histiaeus had accompanied Darius on campaign in 513 BC, and when offered a reward, had asked for part of the conquered Thracian territory. Although this was granted, Histiaeus's ambition alarmed Darius's advisors, and Histiaeus was thus further 'rewarded' by being compelled to remain in Susa as Darius's "Royal Table-Companion". Taking over from Histiaeus, Aristagoras was faced with bubbling discontent in Miletus. In 500 BC, Aristagoras was approached by some exiles from Naxos, who asked him to take control of the island. Seeing an opportunity to strengthen his position in Miletus by conquering Naxos, Aristagoras approached the satrap of Lydia, Artaphernes, with a proposal. If Artaphernes provided an army, Aristagoras would conquer the island, thus extending the boundaries of the empire for Darius, and he would then give Artaphernes a share of the spoils to cover the cost of raising the army. Artaphernes agreed in principle, and asked Darius for permission to launch the expedition. Darius assented to this, and a force of 200 triremes was assembled in order to attack Naxos the following year.
Naxos campaign (499 BC)
In the spring of 499 BC, Artaphernes readied the Persian force, and placed his cousin Megabates in command. He then sent ships on to Miletus, where the Ionian troops levied by Aristagoras embarked, and the force then set sail for Naxos.
The expedition quickly descended into a debacle. Aristagoras fell out with Megabates on the journey towards Naxos, and Herodotus says that Megabates then sent messengers to Naxos, warning the Naxians of the force's intention. It is also possible, however, that this story was spread by Aristagoras after the event, by way of a justification for the subsequent failure of the campaign. At any rate, the Naxians were able to prepare properly for a siege, and the Persians arrived to a well-defended city. The Persians laid siege to the Naxians for four months, but eventually they and Aristagoras both ran out of money. The force sailed back to the mainland without a victory.
Start of the Ionian Revolt (499 BC)
With the failure of his attempt to conquer Naxos, Aristagoras found himself in dire straits; he was unable to repay Artaphernes, and had, moreover, alienated himself from the Persian royal family. He fully expected to be stripped of his position by Artaphernes. In a desperate attempt to save himself, Aristagoras chose to incite his own subjects, the Milesians, to revolt against their Persian masters, thereby beginning the Ionian Revolt.
In autumn 499 BC, Aristagoras held a meeting with the members of his faction in Miletus. He declared that in his opinion the Milesians should revolt, to which all but the historian Hecataeus agreed. At the same time, a messenger sent by Histiaeus arrived in Miletus, imploring Aristagoras to rebel against Darius. Herodotus suggests that this was because Histiaeus was desperate to return to Ionia, and thought he would be sent to Ionia if there was a rebellion. Aristagoras therefore openly declared his revolt against Darius, abdicated from his role as tyrant, and declared Miletus to be a democracy. Herodotus has no doubt that this was only a pretence on Aristagoras's part of giving up power. Rather it was designed to make the Milesians enthusiastically join the rebellion. The army that had been sent to Naxos was still assembled at Myus and included contingents from other Greek cities of Asia Minor (i.e. Aeolia and Doris) as well as men from Mytilene, Mylasa, Termera and Cyme. Aristagoras sent men to capture all the Greek tyrants present in the army and handed them over to their respective cities in order to gain the cooperation of those cities. Bury and Meiggs stated that the handovers were done without bloodshed with the exception of Mytilene, whose tyrant was stoned to death; tyrants elsewhere were simply banished. It has also been suggested (Herodotus does not explicitly say so) that Aristagoras incited the whole army to join his revolt, and also took possession of the ships that the Persians had supplied. If the latter is true, it may explain the length of time it took for the Persians to launch a naval assault on Ionia, since they would have needed to build a new fleet.
Although Herodotus presents the revolt as a consequence of Aristagoras and Histiaeus's personal motives, it is clear that Ionia must have been ripe for rebellion anyway. The primary grievance was the tyrants installed by the Persians. While Greek states had in the past often been ruled by tyrants, this was a form of government on the decline. Moreover, past tyrants had tended (and needed) to be strong and able leaders, whereas the rulers appointed by the Persians were simply the representatives of the Persians. Backed by Persian military might, these tyrants did not need the support of the population, and could thus rule absolutely. Aristagoras's actions have thus been likened to tossing a flame into a kindling box; they incited rebellion across Ionia, and tyrannies were everywhere abolished, and democracies established in their place.
Aristagoras had brought all of Hellenic Asia Minor into revolt, but evidently realised that the Greeks would need other allies in order to successfully fight the Persians. In the winter of 499 BC, he first sailed to Sparta, the pre-eminent Greek state in matters of war. However, despite Aristagoras's entreaties, the Spartan king Cleomenes I turned down the offer to lead the Greeks against the Persians. Aristagoras therefore turned instead to Athens.
Athens had recently become a democracy, overthrowing its own tyrant Hippias. In their fight to establish the democracy, the Athenians had asked the Persians for aid (which was not in the end needed), in return for submitting to Persian overlordship. Some years later, Hippias had attempted to regain power in Athens, assisted by the Spartans. This attempt failed and Hippias fled to Artaphernes, and tried to persuade him to subjugate Athens. The Athenians dispatched ambassadors to Artaphernes to dissuade him from taking action, but Artaphernes merely instructed the Athenians to take Hippias back as tyrant. Needless to say, the Athenians had balked at this, and resolved instead to be openly at war with Persia. Since they were already an enemy of Persia, Athens was already in a position to support the Ionian cities in their revolt. The fact that the Ionian democracies were inspired by the example of the Athenian democracy no doubt helped persuade the Athenians to support the Ionian Revolt, especially since the cities of Ionia were (supposedly) originally Athenian colonies.
Aristagoras was also successful in persuading the city of Eretria to send assistance to the Ionians for reasons that are not completely clear. Possibly commercial reasons were a factor; Eretria was a mercantile city, whose trade was threatened by Persian dominance of the Aegean. Herodotus suggests that the Eretrians supported the revolt in order to repay the support the Milesians had given Eretria some time previously, possibly referring to the Lelantine War. The Athenians sent twenty triremes to Miletus, reinforced by five from Eretria. Herodotus described the arrival of these ships as the beginning of troubles between Greeks and barbarians.
Ionian offensive (498 BC)
Over the winter, Aristagoras continued to foment rebellion. In one incident, he told a group of Paeonians (originally from Thrace), who Darius had brought to live in Phrygia, to return to their homeland. Herodotus says that his only purpose in doing this was to vex the Persian high command.
Sardis
In the spring of 498 BC, an Athenian force of twenty triremes, accompanied by five from Eretria, set sail for Ionia. They joined up with the main Ionian force near Ephesus. Declining to personally lead the force, Aristagoras appointed his brother Charopinus and another Milesian, Hermophantus, as generals.
This force was then guided by the Ephesians through the mountains to Sardis, Artaphernes's satrapal capital. The Greeks caught the Persians unaware, and were able to capture the lower city. However, Artaphernes still held the citadel with a significant force of men. The lower city then caught on fire, Herodotus suggests accidentally, which quickly spread. The Persians in the citadel, being surrounded by a burning city, emerged into the market-place of Sardis, where they fought with the Greeks, forcing them back. The Greeks, demoralised, then retreated from the city, and began to make their way back to Ephesus.
Herodotus reports that when Darius heard of the burning of Sardis, he swore vengeance upon the Athenians (after asking who they indeed were), and tasked a servant with reminding him three times each day of his vow: "Master, remember the Athenians".
