Bardiya

Bardiya or Smerdis, also named as Tanyoxarces by Ctesias, was a son of Cyrus the Great and the younger brother of Cambyses II, both Persian kings. There are sharply divided views on his life. Bardiya either ruled the Achaemenid Empire for a few months in 522 BCE, or was impersonated by a magus called Gaumata, whose name is given by Ctesias as Sphendadates, until he was toppled by Darius the Great.
