He was apparently a great-grandson of its founder Achaemenes, grandson of Teispes and son of Cyrus I.

This alliance likely helped in securing the support or neutrality of Media as his son, Cyrus, began his military campaigns that eventually led to the founding of the Persian Empire.

His role was essential in the transition from a minor regional rule in Anshan to the larger ambitions of the Achaemenid dynasty that dominated much of the ancient Near East.

According to Nicolas of Damascus, his original name was Atradates, and he was wounded and later died in the Battle of the Persian Border which he, with his son, fought against Astyages.

This was not quite the case with Cyrus the Great who would go on to depose his grandfather, and to begin the Persian Empire.
