Achaemenid Persia

The Achaemenid solution to governing enormous diversity was to govern lightly and consistently. The empire was divided into satrapies under governors who collected tribute, maintained order and raised troops, while local law, language, religion and elites were largely left in place. What the centre required was payment, loyalty and troops on demand.

The infrastructure that made this work was communication. The Royal Road ran some 2,500 kilometres from Sardis to Susa with staging posts at intervals, and the mounted courier system, the angareion, could carry a message the length of it in days rather than months. Herodotus’s admiring description of couriers stopped by neither snow nor rain is the origin of a phrase still carved on post offices.

The kings asserted their legitimacy rather than negotiating it, and they asserted it in stone. At Behistun, some sixty metres up a cliff above the road from Babylon to Ecbatana, Darius had his account of his seizure of power carved in three languages, with a relief of himself treading on a usurper and nine roped rebels before him. It sat where everyone could see it and nobody could reach or alter it, and copies went out across the empire in Aramaic. His version of a very doubtful succession is the version that survives.

The Cyrus Cylinder belongs here too. It is regularly described as the first charter of human rights, and it is nothing of the kind. It is a Babylonian foundation deposit in a genre centuries old, in which a new king explains that the previous one offended Marduk. Amélie Kuhrt, the historian of the ancient Near East, makes the necessary point that it tells us about a genre and a political programme, not a philosophical commitment.

The Achaemenid army was an imperial army in the fullest sense: contingents drawn from every subject people, fighting in their own equipment and style under their own leaders, coordinated by a Persian command. Herodotus’s catalogue of the invasion force is a list of peoples, and while his numbers are fantastical the diversity is not.

At its core stood the professional guard the Greeks called the Immortals, kept permanently at ten thousand by replacing every casualty at once. Persian tactical strength lay in cavalry and massed archery, meant to break formations at range before the armies closed. That worked well against most opponents and badly against a determined heavy-infantry phalanx on ground that neutralised horses.

The navy was not Persian at all. It was Phoenician, Egyptian, Cypriot and Ionian Greek, supplied by maritime subjects, which made Persian sea power dependent on the loyalty of the very coastal peoples most likely to revolt. Salamis is partly a story about that dependency.

The Greek wars loom disproportionately because Greeks wrote them up. From Persepolis they were a frontier problem at the far western edge of the empire, which failed and was set aside. The empire’s serious military commitments were elsewhere: Egypt, which revolted repeatedly and had to be reconquered, and the steppe frontier where Cyrus himself is said to have died.

The Achaemenid state was the first to run one fiscal system across many currencies, languages and pre-existing economies. The centre assessed each satrapy a fixed annual tribute in silver or in kind, which gave regions that had never shared a unit of account a common one.

Coinage was introduced deliberately: the gold daric and the silver siglos, carrying an image of the king as archer, minted to reliable standards and circulating widely. The daric kept its reputation for purity for centuries, and it was the first coinage anywhere in the Archives meant to work across an empire rather than to advertise a city.

The Persepolis Fortification tablets show the internal economy at operating level: rations of grain, wine and beer issued against named authorisations, travel provisions for people moving along the roads under sealed orders, livestock accounted, commodities transferred between storehouses. It is a redistributive command economy running alongside a monetised one, documented in fifteen years of paperwork.

Infrastructure investment was substantial and pragmatic: the qanat underground irrigation channels that made settlement possible on the Iranian plateau, and Darius’s canal linking the Nile to the Red Sea, commemorated in a quadrilingual stele that is itself a statement about who the empire thought it was.

This is where the Greek picture fails most completely, and the correction is documentary. The Persepolis tablets record women working throughout the royal economy, in textile production, wine-making and food processing. They received rations on the same scale as men doing equivalent work.

Pregnant women received enhanced rations, and nursing mothers received an additional allocation designated for the infant. A category of women called araššara appear as supervisors, heading work gangs at managerial ration rates and occasionally named as the authorising official on a transaction. One of the most extensively documented individuals in the entire archive is Irdabama, a woman who ran a large labour force and travelled with her own retinue, and who is not identified as a queen or a king’s wife.

Set that against Herodotus, Ctesias and Plutarch, who present Achaemenid women almost exclusively through court intrigue: Atossa steering foreign policy, Parysatis arranging poisonings, power exercised sideways from a harem. The Dutch historian Heleen Sancisi-Weerdenburg argued in her article ‘Exit Atossa’ that these figures are largely literary constructions serving Greek narrative needs. The Greeks did not invent everything. They simply had no category for what the tablets show again and again.

The workforce came from all over the empire. The tablets label the kurtaš by origin, as Egyptians, Lydians, Carians, Thracians, Indians and Babylonians, and their personal names follow the sound patterns of the matching languages. The labels record real people moved across enormous distances, not administrative categories.

The Achaemenid kings worshipped Ahura Mazda and said so at every opportunity. Darius’s inscriptions credit him with the kingdom, with victory and with truth, and set the world in a moral frame divided between arta, truth or right order, and drauga, the Lie, with every rebel classified as a liar and every suppression as cosmic maintenance.

Whether that makes them Zoroastrian in a strict sense is disputed. Zarathustra’s dating is uncertain, the royal inscriptions never mention him, and the practices they describe do not match later Zoroastrian orthodoxy in several respects. The safest statement is that Achaemenid royal religion drew on the same Iranian religious world that produced Zoroastrianism.

The famous tolerance is real, limited and best understood as policy. Cyrus permitted the return of deported peoples and the restoration of their cults, and the Persian state funded and protected local religious institutions across the empire, a practice that bought loyalty cheaply. But Persian kings also destroyed sanctuaries when suppressing revolt, and the tolerance was not a principle so much as an instrument that worked.

The Persepolis tablets settle the point from below. They record rations issued for religious ceremonies in Elamite, Babylonian and other traditions alongside Ahura Mazda, paid from the same stores by the same officials. The Elamitologist Wouter Henkelman studied that evidence and concluded that the heartland under Darius was a zone of real religious plurality. The inscriptions make declarations, and the accounts pay out.

Achaemenid imperial art was assembled deliberately from the traditions of the empire’s parts, and said so. A foundation inscription from Susa lists the materials and the workmen: cedar from Lebanon, gold from Sardis and Bactria, lapis from Sogdia, stonecutters who were Ionians and Lydians, goldsmiths who were Medes and Egyptians. The building is an argument about the empire made out of the empire.

Persepolis is the fullest statement. The terrace complex, with its apadana audience hall and hundred-columned throne room, was ceremonial rather than administrative, a stage for the New Year reception of the empire. Its great staircase reliefs show delegations from twenty-three peoples bringing gifts, each identifiable by dress, hairstyle and offering, processing calmly toward the king.

Set those reliefs beside Assyrian ones and the difference in tone is plain. There are no flayings, no piles of heads, no siege scenes. The subjects approach as participants in an ordered arrangement rather than as its victims. It is a chosen picture of empire as harmony under a king, and just as much a construction as Assyrian terror was.

Alexander burned Persepolis in 330 BCE, and the destruction of the palaces preserved the thing that has changed the field: the archive of tablets sealed in the fortification wall, protected because they were administrative waste that nobody thought to remove.

The Achaemenids ran their empire in Aramaic. It was nobody’s imperial language by right. It was a Semitic tongue with a simple alphabetic script, already widespread as a language of commerce, and using it for the chancery meant orders could be drafted centrally and translated locally where they were delivered. It is an early and effective answer to governing people who do not share a language.

Old Persian cuneiform, by contrast, appears to have been designed rather than evolved, possibly for Behistun itself. It was a small, mostly alphabetic set of signs used almost only for royal inscriptions, a display script for the dynasty rather than a working one. That is why so little Persian-language administration survives, and why the Persepolis archive is in Elamite.

That layering of languages had a modern consequence. Because Old Persian was simple and the Behistun text existed in three scripts, it cracked cuneiform open in the nineteenth century, and through it Akkadian, and through that the entire literature of Mesopotamia. Darius’s monument to himself became the key to civilisations a thousand years older than his own.

Persian scientific and scholarly achievement in this period is mostly a matter of patronage and transmission rather than original production: Babylonian astronomy continued and improved under Persian rule, Egyptian medicine was employed at court, and Indian, Mesopotamian and Greek knowledge circulated through an empire that connected all three.

The Achaemenid source problem is the sharpest of the twenty-seven. An empire of enormous size left very little continuous narrative of its own, and the fullest account of it was written by a citizen of a state it had invaded.

Herodotus is valuable, curious, wide-ranging and often careful to report competing versions, and he is structurally committed to a story in which Greek freedom defeats Persian despotism. Ctesias served as a physician at the court of Artaxerxes II and should therefore be a superb witness, yet he is often unreliable in detail and drawn to intrigue. Both have to be read as evidence for Greek perception as much as Persian reality.

The corrective material is administrative and multilingual: the Persepolis Fortification and Treasury tablets in Elamite, Babylonian business archives showing what Persian rule meant on the ground, the Aramaic papyri from the Jewish garrison community at Elephantine in Egypt, which include letters to the satrap, and royal inscriptions in Old Persian, Elamite and Babylonian.

The Chicago Elamitologist Richard Hallock published 2,087 tablets in 1969. The archive holds roughly thirty thousand, and most are still unpublished more than half a century later, with the work further held up by American litigation that treated the tablets as Iranian state assets. The most important body of evidence for this civilisation is still largely unread.
