Aristagoras, the Milesian tyrant (acting under Persian authority), joins Persian satrap Artaphernes in an attempt to seize Naxos; the failure leaves Aristagoras politically exposed and helps set the stage for revolt.
After the Naxos debacle, Aristagoras proclaims constitutional government at Miletus; across Ionia, Persian-backed tyrants are expelled as the uprising against Darius I spreads.
Aristagoras seeks mainland Greek support; Sparta declines, while Athens promises 20 triremes and Eretria 5, providing the revolt with limited but symbolically important allies.
Ionian forces joined by Athenians and Eretrians seize much of Sardis, the satrapal capital of Lydia; the city is set on fire during the operation, hardening Persian resolve and escalating the conflict.
As the allied force withdraws, Persian troops defeat the Ionians and their mainland Greek allies near Ephesus; Athens and Eretria subsequently abandon the expedition, leaving the revolt more isolated.
Despite the setback, uprisings expand beyond Ionia to Cyprus, Caria, and Greek communities around the Bosporus/Hellespont, forcing Persia to respond on multiple fronts.
In the next campaigning season, Persian commanders (including Daurises, Hymaees, and Otanes) lead coordinated offensives to recover rebellious regions around the Hellespont/Propontis and to pressure Ionia and Caria.
With Persian pressure increasing, Aristagoras leaves Ionia to attempt a new base in Thrace; he is killed there, depriving the revolt of its original political organizer.
Persia reconquers Cyprus after a combined land-and-sea struggle near Salamis: the Ionians defeat the Phoenician fleet at sea, but Persian victory on land breaks the Cypriot revolt and restores Persian control.
In Caria, rebels inflict a severe defeat on a Persian force in an ambush at Pedasus/Pedasa; the loss disrupts Persian operations and contributes to a temporary lull before the final Persian concentration on Miletus.
A large Persian fleet meets the Ionian coalition fleet near Lade (off Miletus) and wins decisively; the collapse of Ionian naval resistance makes Miletus vulnerable and effectively decides the revolt militarily.
After Lade, Persia besieges and captures Miletus, the revolt’s focal city; ancient accounts and archaeology indicate heavy destruction and deportations/enslavement, making the fall a watershed in the revolt’s collapse.
Histiaeus—former tyrant of Miletus—attempts to reassert himself after leaving Persia but is captured; Artaphernes executes him, eliminating a prominent figure associated with the revolt’s origins.
Persian forces conduct final operations against remaining resistance, including assaults on islands such as Chios, Lesbos, and Tenedos and reassertion of control along the Hellespont and coastal cities of Ionia.
After suppression, satrap Artaphernes compels inter-city arbitration agreements, surveys Ionian territory, and sets tributes—measures presented in Herodotus as stabilizing Persian rule and reducing internal Greek conflicts.
