With defeat at Lade, the Ionian Revolt was all but ended. The next year, the Persians reduced the last rebel strongholds, and began the process of bringing peace to the region. 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 for the revolt. Moreover, seeing that the myriad city states of Greece posed a continued threat to the stability of his empire, he decided to conquer the whole of Greece. In 492 BC, the first Persian invasion of Greece, the next phase of the Greco-Persian Wars, would begin as a direct consequence of the Ionian Revolt.
