Artaxerxes IV Arses
Artaxerxes IV (old-Persian Artakhšaça): name of a Achaemenian
king of the Persian empire, ruled 338-336. His real name was Arses.
Arses was a son of the Persian king Artaxerxes III Ochus (358-338),
and the only one who survived the poisoning of the royal family by the
powerful eunuch Bagoas. This happened in the summer of 336, and it is
probable that Bagoas killed everyone to make sure that Arses, who seems
to have been some sort of a puppet king, became the new ruler of the
Persian empire.
From cuneiform texts, we know that Arses accepted the same throne name
as his father and grandfather, Artaxerxes.
The assassination caused great upheavals in the Persian empire and
it is certain that Bagoas and Artaxerxes IV were unable to get a firm
grasp on the situation. At least two satrapies revolted: Egypt, which
had recently been conquered by Artaxerxes III, and Babylonia (although
the evidence for the insurrection of Nidin-Bêl is meager). To
add to these troubles, the king of Macedonia, Philip, prepared an attack
on Persia's possessions in what is now Turkey: his trusted general Parmenion
crossed the Hellespont in the spring of 336.
Under these circumstances, it comes as no surprise that the Persian
nobility was divided. Prince Artašata, a distant relative of Artaxerxes,
seems to exercised pressure. He was a powerful man and a formidable
warrior, and he received support from several noblemen (e.g., Pharnabazus).
It seems that Artaxerxes wanted to remove Bagoas (click here for the
story) and that this forced Bagoas to kill this king as well (summer
of 336). Artašata now became king under the name of Darius III
Codomannus.
One of his first acts was the execution of Bagoas. For a few months
there was a respite: there was a strong king who was able to reunite
the kingdom, and Philip was murdered (October 336). Moreover, a Greek
mercenary general in Persian service, Memnon of Rhodes, started to push
back Parmenion. However, Philip was succeeded by his young son Alexander
the Great, who joined Parmenion (May 334), and launched the campaign
that ended with the fall of the Persian empire (330).
In 324, Alexander married to Arses' sister Parysatis.
