Ochus becomes Artaxerxes III
Ochus, son of Artaxerxes II and Stateira, became king as Artaxerxes. The Babylonian era counts his reign from November 359; Polyaenus (7.17) says he hid his father’s death for ten months. According to Justin he killed his brothers, sisters and other rivals.

A life in order
Ochus, son of Artaxerxes II and Stateira, took part c. 361 in a campaign against Egypt and received the surrender of Pharaoh Tachos. He removed his brothers to secure the succession and became king as Artaxerxes in 359/358. He fought the Cadusii, brought the rebel western satraps to heel, ended the Phoenician revolt with the destruction of Sidon and in 343/342 recovered Egypt after some sixty years. In 338 he was poisoned by Bagoas.

Iranica calls him energetic, crafty and strong-minded, a king who “revived the old empire of Darius”; Greek sources call him cruel and violent, but also a fair judge (Diodorus 16.49.6).
Central power can be rebuilt by force, but when everything hangs on one man, everything falls with his death.

Name: Ochus and Artaxerxes
His personal name was Ochus, Babylonian Umakuš, the same as Darius II’s; Artaxerxes was his throne name. Greek writers mostly call him Ochus.
No well-known contemporary epithet, of praise or blame, is attested; what survives are later verdicts on his violence.
Where there is no source, inventing an epithet is a kind of forgery.

Ending the Satraps’ Revolt: dismiss the mercenaries
Artaxerxes III ordered the western satraps to dismiss their Greek mercenaries (scholium on Demosthenes 4.19). Orontes submitted; Artabazus, helped by the Athenian Chares, fled to Macedon. By threat of war the king made Athens drop Artabazus. The actual restoration of order was done by generals, above all Mentor of Rhodes.
Ordering the mercenaries dismissed struck at the satraps’ power base, their private armies. Yet the king too won with Greek generals and mercenaries; dependence on hired soldiers did not end, it moved to the centre.
A state monopoly of force, unless bound by law, only moves the danger.

Sidon: revolt, betrayal and fire
In 351 Syria, Phoenicia and Cyprus revolted under Tennes, king of Sidon, with Nectanebo’s support. Diodorus says the cause was the arrogance of the Persian satraps and commanders at Sidon. The neighbouring satraps achieved nothing; the king came from Babylon himself. Tennes betrayed the city and the Sidonians, who had earlier burned their ships so that no one could flee, set the city ablaze with themselves inside. The king then had Tennes killed too.
Diodorus’ account is dramatic and his figures exaggerated, but the pattern is clear: a rich city that had borne heavy dues and abuse revolted, and its destruction was a warning to others.
A government whose officials drive thriving cities to revolt, and which then destroys them, burns its own capital.

The reconquest of Egypt
After an earlier failure, the king led a large army to Egypt in person. Pelusium and Bubastis fell and Egypt was a satrapy again after some sixty years; Pherendates was made satrap and Nectanebo II fled to Nubia. The Persians plundered widely; Diodorus says Bagoas carried off the ancient temple records and sold them back to the priests for huge sums (16.51.2).

Aelian’s story that the king killed the Apis bull and the Egyptians called him “the ass” (4.8) is hostile Egyptian tradition and cannot be taken as evidence. But the plunder and the resale of records show what the reconquest rested on: taking, not keeping.
When a conqueror holds a society’s records and memory hostage and sells them back, rule has become extortion.

The Greeks, Philip and Perinthus
Artaxerxes sought the friendship of Athens, Sparta and Macedon. About 351 he invited Athens and Sparta to join his Egyptian war; both declined but professed friendship; Thebes and Argos sent troops. He made a treaty of friendship with Philip II. But when Philip besieged Perinthus in 340, the king ordered his satraps to help the city. Alexander later cited this in a letter to Darius III.
For you sent aid to the Perinthians, who were dealing unjustly with my father; and Ochus sent forces into Thrace, which was under our rule.
Arrian gives the text of Alexander’s letter, but Badian warns that documents quoted in the Greek sources are usually fictitious; the letter shows Alexander’s propaganda case more than a record.
A pretext for war can always be found; what matters is who writes the story.

The Persepolis palace and tomb
Artaxerxes III built a palace on the south-western part of the Persepolis terrace, attested by his inscription A3Pa on a stairway; an Akkadian tablet of his was also found at Susa. One of the two Kuh-e Rahmat tombs at Persepolis is ascribed to him.


Renewed building at Persepolis was a token of revived royal authority.
Buildings attest power, not the consent of the governed.

Bagoas and the end
Bagoas, the Egyptian-born chiliarch who had served in the conquest of Egypt, poisoned the king according to Diodorus (17.5.3–4) and killed all his sons except the youngest, Arses, who reigned about two years. Bisthanes, another son of Artaxerxes III, came to meet Alexander in 330 (Arrian 3.19.4).
Iranica judges the king’s early death a serious misfortune for the Persian kingdom: four years later Alexander crossed into Asia.
Power built on fear is vulnerable to its closest courtier.

Synthesis: revival by force
Artaxerxes III reunited the empire that had been coming apart under his father: the satraps were tamed, Phoenicia submitted and Egypt returned. In holding the frontiers it was the most successful Achaemenid reign since Xerxes.
But his tools were force, killing and plunder. The thriving cities of Sidon and Egypt were destroyed or looted, and even the temples’ records were held to ransom. An empire resting on fear rather than on the security of its people’s lives and property shook when one man was murdered by his courtier, and a few years later collapsed before Alexander.
