Ionian Revolt
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.
