Bardia or Bardiya (Old Persian: 𐎲𐎼𐎮𐎡𐎹Bardiya;Ancient Greek: Σμέρδις Smerdis) (possibly died 522 BC) 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. He either ruled the Achaemenid Empire for a few months in 522 BC, or was impersonated by a magus called Gaumāta. (Old Persian: 𐎥𐎢𐎶𐎠𐎫)
The prince's name is listed variously in the historical sources. His Persian name is Bardia or Bardiya. He is called Tonyoxarces (Sphendadates) by Ctesias, he is called Tanooxares by Xenophon, who takes the name from Ctesias, and he is called Mardos by Justin and Aeschylus. In the prevalent Greek form of his name, Smerdis, the Persian name has been assimilated to the Greek (Asiatic) name Smerdis or Smerdies, a name which also occurs in the poems of Alcaeus and Anacreon.
In English-language histories he has traditionally been called Smerdis, but recent histories tend to call him Bardiya.
The traditional view is based on the majority of ancient sources, e.g., Darius the Great's Behistun inscription, as well as Herodotus, Justin, and Ctesias, although there are minor differences between them.
