The major event of these three reigns was the Peloponnesian War between Sparta and Athens, which was fought, with occasional pauses, over the latter decades of the 5th century bc. The situation was ripe for exploitation by the famous “Persian archers,” the gold coins of the Achaemenids that depicted an archer on their obverse and that were used with considerable skill by the Persians in bribing first one Greek state and then another. Initially the Persians encouraged Athens against Sparta and from this gained the Peace of Callias. Then, after the disastrous Athenian campaign against Sicily in 413, the Persians intervened on Sparta’s side. By the treaty of Miletus in 412, the Persians recovered complete freedom in western Asia Minor in return for agreeing to pay for seamen to man the Peloponnesian fleet. Persian gold and Spartan soldiers brought about the fall of Athens in 404 bc. Despite the fact that the Persians played the two sides against each other to their own advantage, they should have done better. One observes a certain lack of control from Susa by the king in these proceedings, and the two principal governors in Asia Minor who were involved, Tissaphernes of Sardis and Pharnabazus of Hellespontine Phrygia, seemed to have permitted a personal power rivalry to stand in the way of a really coordinated Persian intervention in the Greek war. When Egypt revolted in 405 bc, Persia was unable to do much about it, and from that point forward Egypt remained essentially an independent state.
Artaxerxes II came to the throne in 404 and reigned until 359 bc. The main events of his long rule were the war with Sparta that ended with a peace favourable to the Persians; the revolt and loss to the empire of Egypt; the rebellion of Cyrus the Younger, brother of the king; and the uprising known as the revolt of the satraps.
Sparta, triumphant over Athens, built a small empire of its own and was soon involved in a war against the Persians, the principal issue again being the Greek cities of Asia Minor. While Sparta played one Persian governor in Anatolia against the other, the Persians spent gold in Greece to raise rebellion on Sparta’s home ground. The Persians rebuilt their fleet and placed a competent Athenian admiral, Conon, in command. The contest continued from 400 to 387, with Sparta forced to act on an ever-shrinking front. A revitalized Athens, supported by Persia, created a balance of power in Greece, and eventually Artaxerxes was able to step in, at the Greeks’ request, and dictate the so-called King’s Peace of 387–386 bc. Once again the Greeks gave up any claim to Asia Minor and further agreed to maintain the status quo in Greece itself.
Cyrus the Younger, though caught in an assassination attempt at the time of Artaxerxes’ coronation, was nevertheless forgiven and was returned to the command of a province in Asia Minor. But he revolted again in 401 bc and, supported by 10,000 Greek mercenaries, marched eastward to contest the throne. He was defeated and killed at the Battle of Cunaxa in Mesopotamia that summer. The Greek mercenaries, however, were not broken and, though harried, left the field in good order and began their famous march, recorded in the Anabasis of Xenophon, north to the Black Sea and home. Probably no other event in late Achaemenian history revealed more clearly to the Greeks the essential internal weakness of the Achaemenian Empire than the escape of so large a body of men from the very heart of the Persian domain.
Since 379 bc Artaxerxes had been gathering Greek mercenaries in order to mount a campaign against Egypt. An attack in 373 failed against the native Egyptian 30th dynasty. On the heels of this failure came the revolt of the satraps, or provincial governors. Several satraps rose against the central power, and one, Aroandas (Orontes), a satrap of Armenia, went so far as to stamp his own gold coinage as a direct challenge to Artaxerxes. The general plan of the rebels appears to have been for a combined attack. The rebel satraps were to coordinate their march eastward through Syria with an Egyptian attack, under the king Tachos, and support by Greek mercenaries. The Egyptian attack was called off because of a revolt in Egypt by Tachos’s brother, and Artaxerxes managed to defeat the satraps who were left alone to face the king’s wrath. Several of the satraps, including Aroandas, were actually forgiven and returned to their governorships. In general the impression is that, in the end, rather than fight the central authority, the satraps were willing to return to their own provinces and plunder there in the name of Artaxerxes. Perhaps they saw that they actually had more authority and more control over real events in their own provincial territories than Artaxerxes had in his empire.
Plot and counterplot, harem intrigue, and murder brought Artaxerxes III to the throne in 359 bc. He promptly exterminated many of his relatives who might have challenged his rule—all to no avail, for revolts continued to rock the empire. A fresh attempt to win back Egypt was repulsed in 351. This setback encouraged revolt in Sidon and eventually in all of Palestine and Phoenicia. Parts of Cilicia joined the rebellion, but the revolt there was crushed in 345, the same year it had begun. Peace was achieved only temporarily; mercenaries from Thebes and the Argives, as well as from the Greek cities of Asia Minor, gathered for a new attempt on Egypt. Led by Artaxerxes III himself, it succeeded in 343 bc. But the local Egyptian dynasty fled south to Nubia, where it maintained an independent kingdom that kept alive the hopes of a dynastic revival. Persia then misplayed its hand in Greece by refusing aid to Athens against the rising power of Philip II of Macedon. In 339 bc Persian troops were fighting alone in Thrace against the Macedonians, and in the following year, at the Battle of Chaeronea, Philip extended his hegemony over all of Greece—a united Greece that was to prove impervious to Persian gold.
Artaxerxes was poisoned by his physician at the order of the eunuch Bagoas. The latter made Artaxerxes’ youngest son, Arses, king (338–336 bc) in hopes of being the power behind the throne, but Arses did not bend easily to Bagoas’s will. He attempted to poison the kingmaker but was himself killed in retaliation. Bagoas then engineered the accession of Darius III, a 45-year-old former satrap of Armenia. So many members of the royal house had been murdered in the court intrigue that Darius probably held the closest blood claim to the throne by virtue of being the grandnephew of Artaxerxes II. Darius was able to put down yet another rebellion in Egypt under Khababash in 337–336 bc, but the beginning of the end of the Achaemenian Empire came soon afterward, in May 334, when he lost the Battle of Granicus to Alexander the Great. Persepolis fell to the invader in April 330, and Darius, the last Achaemenid, was murdered in the summer of the same year while fleeing the conqueror. His unfinished tomb at Persepolis bears witness to his lack of preparation.
Alexander did not win his victories easily, however, and the catalog of troubles that marked the latter part of the Achaemenian Empire—rebellions, murders, weak kings trapped in the harems, missed chances, and foolish policies—cannot be the whole story. The sources, mostly Greek, are often prejudiced against the Persians and tend to view events from but a single point of view. No government could have lasted so long, found its way somehow through so many difficulties, and in the end actually have fought so hard against the conqueror without having much virtue with which to balance its vices. Achaemenian society and culture
The culture that developed under the Achaemenids was in reality the collective societies and cultures of the many subject peoples of the empire. From this mosaic it is sometimes difficult to sort out that which is distinctively Persian or distinctively a development of the Achaemenian period and therefore perhaps an early Iranian contribution to general Middle Eastern society and culture. Language
The languages of the empire were as varied as its peoples. The Persians, at least originally, spoke Old Persian, a southwestern dialect of Iranian (Median was a northwestern Iranian dialect), and were a nonliterate society. Their language was first written when Darius commanded that a script suitable for this purpose be invented so that he might inscribe the record of his rise to power at Bīsotūn (the inscriptions in Old Persian attributed to earlier kings were likely written during the reign of Darius or are later historical forgeries). That few could read Old Persian might be the reason why Darius at Bīsotūn established the tradition that royal inscriptions should be trilingual in Old Persian, Babylonian, and Elamite. Old Persian was never a working written language of the empire. Elamite, written on clay tablets, appears to have been the language of many of the administrators in Persis and, it may be assumed, in Elam. Archives of administrative documents in Elamite have been found at Persepolis. Aramaic, however, was the language of much of the empire and was probably the language most used in the imperial bureaucracy. The beginnings of the strong influence of Aramaic on Persian, which is so evident in the Middle Persian of Sāsānian times, can already be seen in the Old Persian royal inscriptions of late Achaemenian times.
