Phraates II (Persian: فرهاد دوم) of Parthia, son of Mithridates I of Parthia (171–128 BC), the conqueror of Babylon, ruled the Parthian Empire of Iran from 138 BC to 128 BC. He was attacked in 130 BC by Antiochus VII Sidetes (138–129 BC), ruler of the Seleucid Empire. Antiochus VII, however, after great initial success, was defeated and killed in battle in Media in 129 BC, which ended the Seleucid rule east of the Euphrates.
Meanwhile Parthia was invaded by the nomadic Saka and Tochari. Phraates II marched against them, his army including a large force of captured Seleucid soldiers from the army of the late Antiochus VII Sidetes. These ultimately refused to fight for the Parthian king, and he was defeated and killed in a great battle inside and around Media.
