Ariaramnes
Ariaramnes ( Old Persian: ???????????????????????????????? Ariyāramna, "He who brings peace to the Aryans (i.e. Iranians)") was a great uncle of Cyrus the Great and the great-grandfather of Darius I, and perhaps the king of Parsumash, the ancient core kingdom of Persia.
Ariaramnes was most likely the brother of Cyrus I of Anshan and son of Teispes, but this is not certain. In any case, he was a member of the Achaemenid House. As supported by the relief at Bisitun he was the first king of a separate Achaemenid branch that ran parallel to the reigns of Cyrus I and his son Cambyses I.
