If we were to ascribe the Chehl Minar itself to him, we should have to give him the palm above all other kings of Persia; but on the whole it is most probable that that edifice and its duplicate at Susa were conceived, and in the main, constructed, by Darius.
Xerxes left behind him three sons--Darius, Hystaspes, and Artaxerxes--and two daughters, Amytis and Rhodogune.

Hystaspes was satrap of Bactria, and at the time of their father's death, only Darius and Artaxerxes were at the Court.
Fearing the eldest son most, Artabanus persuaded Artaxerxes that the assassination of Xerxes was the act of his brother, whereupon Artaxerxes caused him to be put to death, and himself ascended the throne (B.C.
465).
Troubles, as usual, accompanied this irregular accession.

Artabanus, not content with exercising an influence under Artaxerxes such as has caused some authors to speak of him as king, aimed at removing the young prince, and making himself actual monarch.

But his designs being betrayed to Artaxerxes by Megabyzus, and at the same time his former crimes coming to light, he was killed, together with his tool Aspamitres, seven months after the murder of Xerxes.

The sons of Artabanus sought to avenge his death, but were defeated by Megabyzus in an engagement, wherein they lost their lives.
Meanwhile, in Bactria, Hystaspes, who had a rightful claim to the throne, raised the standard of revolt.
