Ionian Revolt
Artaphernes (, Old Persian: Artafarna, from Median "Rtafarnah"), flourished circa 513–492 BC, was a brother of the Achaemenid king of Persia, Darius I, satrap of Lydia from the capital of Sardis, and a Persian general. In his position he had numerous contacts with the Greeks, and played an important role in suppressing the Ionian Revolt.
