Behistun Inscription in
Kermanshah. The traditional view is based on several ancient sources, including the Behistun inscription as well as Herodotus, in Ctesias, and Justin, although there are minor differences among them. The three oldest surviving sources agree that Gaumata/Pseudo-Smerdis/Sphendadates was overthrown by
Darius and others in a coup d'état, and that Darius then ascended the throne. Most sources (including Darius himself, Herodotus and Ctesias) have Darius as part of a group of seven conspirators. In Greek and Latin sources, Darius subsequently gained kingship by cheating in a contest. Bardiya was the younger son of
Cyrus the Great and a full or half-brother of
Cambyses II. According to Ctesias, on his deathbed Cyrus appointed Bardiya as
satrap (governor) of some of the far-eastern provinces. According to Darius the Great, Cambyses II, after becoming king of Persia but before setting out for
Egypt, killed Bardiya and kept this secret. However, according to Herodotus (who gives two detailed stories), Bardiya went to Egypt with Cambyses and was there for some time but later Cambyses sent him back to
Susa out of envy, because "Bardiya alone could draw the bow brought from the Ethiopian king." Herodotus then states that "Cambyses had a dream in which he saw his brother sitting on the royal throne. As a result of this dream Cambyses sent his trusted counselor
Prexaspes from Egypt to Susa with the order to kill Smerdis" (i.e., Bardiya). Bardiya's death was not known to the people, and so in the spring of 522 BC, a usurper pretended to be him and proclaimed himself king on a mountain near the Persian town of
Paishiyauvada. Darius claimed that the real name of the usurper was
Gaumata, a
Magian priest from Media; this name has been preserved by
Justin but given to his brother (called
Patizeithes by Herodotus), who is said to have been the real promoter of the intrigue. According to Herodotus, the name of the Magian usurper was
Oropastes, but according to Ctesias it was
Sphendadates. The despotic rule of Cambyses, coupled with his long absence in Egypt, contributed to the fact that "the whole people, Persians,
Medes and all the other nations," acknowledged the usurper, especially as he granted a tax relief for three years. Cambyses began to march against him, but died in the spring of 522 BC in disputed circumstances. Before his death he confessed to the murder of his brother, and publicly explained the whole fraud, but this was not generally believed. Nobody had the courage to oppose the new king, who ruled for seven months over the whole empire. The new king transferred the seat of government to
Media. A number of Persian nobles discovered that their new ruler was an impostor, and a group of seven nobles formed a plot to kill him. In September 522 BC they surprised him at a castle in Nisa (on the
Nisaean plain) and stabbed him to death. One of the seven, Darius, was proclaimed as ruler shortly after. While the primary sources do not agree on the names and many other details, the three oldest surviving sources (Darius himself, Herodotus and Ctesias) all portray Gaumata/Pseudo-Smerdis/Sphendadates as an imposter who
usurped the throne by posing as one of the sons of Cyrus the Great, i.e. as one of the brothers of
Cambyses II. In Darius' trilingual Behistun inscription, the prince being impersonated is named "Pirtiya" in
Elamite, "Bardiya" in
Old Persian, and "Barziya" in
Akkadian. In Herodotus'
Histories, the prince and his imposter have the same name (Smerdis). For Ctesias, Sphendadates poses as 'Tanyoxarces'. Other Greek sources have various other names for the figure being impersonated, including 'Tanoxares', 'Mergis' and 'Mardos'.
In Herodotus' Histories , to check if King Smerdis has ears under his turban, as the suspected imposter was known to have had them cut off in punishment for a crime. She found that indeed the king did not have ears anymore, which proved that he was an imposter, and justified the coup in favour of
Darius I. and the false Smerdis", 19th century print. in the Achaemenid lineage. A longer version of the story appears in Book 3 of Herodotus'
Histories, written c. 450 BC. That story there (3.1–38, 3.61–88) can be roughly summarized as follows: King Cyrus, as he lay dying, appointed his elder son, Cambyses, to the throne and appointed his younger son, Tanyoxarces, governor of the provinces of
Bactria,
Chorasmia,
Parthia, and
Carmania. Shortly after Cambyses ascends the throne, a certain Sphendadates who had been whipped by Tanyoxarces for some offence, informs Cambyses that his brother is plotting against him. As proof of this he declares that Tanyoxarces would refuse to come if summoned. When Tanyoxarces does not immediately accede to the summons, Cambyses begins to believe Sphendadates, who then begins to slander Tanyoxarces more freely. By the time Tanyoxarces finally arrives, Cambyses is determined to put him to death, but hesitates. Sphendadates suggests that, since he (Sphendadates) looks very much like Tanyoxarces, he could take the prince's place. Cambyses agrees, and Tanyoxarces is killed by being forced to drink
bull's blood. Sphendadates then takes the place as governor of the eastern provinces. Five years later, while in Babylon, Cambyses accidentally wounds himself in the thigh, and dies eleven days later. Upon hearing of Cambyses death, Sphendadates (alias Tanyoxarces) returns to the capital and succeeds Cambyses. Meanwhile, Izabates, a confidant of Cambyses who knew of the killing of Tanyoxarces, is on his way with the body of Cambyses. Upon arriving at the capital and finding Sphendadates on the throne, Izabates exposes the fraud. Then, seven noblemen (among them Darius) conspire against Sphendadates. The seven are admitted to the palace by a co-conspirator, where Sphendadates is then killed. The seven then decide to hold a contest whereby whichever of them got his horse to neigh first after sunrise shall become king. Darius gets his horse to be the first to neigh (F13.17: "the result of a cunning stratagem") and he ascends the throne. == Modern view ==
