The Battle of Ecbatana was fought in 129 BC between the Seleucids led by Antiochus VII Sidetes and the Parthians led by Phraates II. Phraates II (ca. 139/138 BC - ca. 128 BC) faced the final attempt on the part of the Seleucids to regain their power in the east. The Seleucids suffered a crushing defeat at the Battle of Ecbatana and Antiochus VII himself perished. This battle marked the decisive and final defeat for the Seleucid kingdom by the Parthians.
