After a reign of forty-five days, he was assassinated in 424 BC by his brother Sogdianus, who in turn was murdered by Darius II. He is an obscure historical figure known primarily from the writings of Ctesias. He was reportedly the only legitimate son of Artaxerxes I and his Queen Damaspia. He is known to have served as Crown Prince. The last inscription mentioning Artaxerxes I being alive can be dated to December 24, 424 BC. Xerxes apparently succeeded to the throne but two of his illegitimate brothers claimed it for themselves. The first was Sogdianus, son by concubine Alogyne of Babylon. The second was Darius II, son by concubine Cosmartidene of Babylon, who was married to their common half-sister Parysatis, daughter of Artaxerxes I and his concubine Andia of Babylon.
