Dariush, the son of Hystaspes together with six noblemen; Otanes, Gobryas, Intaphrenes, Hydarnes, Megabyzus, and Ardumanis entered the palace and according to a sophisticated plan they had made, they succeeded in a coup against Gaumata and assassinated him. They charged that Gaumata who claimed to be Bardia, the younger son of Cyrus the great was indeed a Magian who resembled him a lot. Therefore putting an end to Gaumata's reign for a couple of months. This story is not easy to believe but that is the text on Behistun Inscription and also Herodotus.
Dariush ascended the throne but his reign was not easy. He had to suppress 19 rebellions against him in diverse parts of the Persian Empire from Babylon to Ecbatana to Lydia.
