Cambyses was an early member of the Achaemenid dynasty. He was apparently a great-grandson of its founder Achaemenes, grandson of Teispes of Anshan and son of Cyrus I of Anshan. His paternal uncle reigned as Ariaramnes of Persia and his first cousin as Arsames of Persia.
According to Herodotus, Cambyses was "a man of good family and quiet habits". He reigned under the overlordship of Astyages, King of Media. He was reportedly married to Princess Mandane of Media, a daughter to Astyages and Princess Aryenis of Lydia. His wife was reportedly a granddaughter to both Cyaxares of Media and Alyattes II of Lydia. The result of their marriage was the birth of his successor Cyrus the Great. According to Nicolas of Damascus his nickname was Atradates, and he was wounded in the Battle of the Persian Border which he, with his son, fought against Astyages, in which he received an honorable burial.
According to Herodotus, Astyages chose Cambyses as a son-in-law because he considered him to pose no threat to the Median throne. This was not the case with Cyrus II who would go on to depose his grandfather.
