Mausolus participated in the Revolt of the Satraps, both on his nominal sovereign Artaxerxes Mnemon's side and (briefly) against him. In 366 BC, Mausolus together with Autophradates of Lydia, at the request of Artaxerxes, led the siege of Adramyttium against Ariobarzanes, one of the members of the Great Satraps' Revolt, until Agesilaus, king of Sparta, negotiated the besiegers' retreat.[2]
