Achaemenid Legacy: Institutions, Scripts and Memory After the Empire

When Alexander, the Macedonian king, conquered the Persian Achaemenid Empire around 330 BCE, he took over provinces already governed through offices, local officials and scribal practices. Successors kept some offices while changing who held them and where royal power was centered. Later Iranian states adapted Aramaic writing to their own languages, while Sasanian kings and medieval worshippers reused Achaemenid royal places.

Satraps and royal relationships

A satrap was a governor of a large province. Alexander sometimes retained existing officials and sometimes appointed trusted replacements. After his victory at Gaugamela in 331 BCE, he appointed the Persian aristocrat Mazaios satrap of Babylonia, with a Macedonian commander controlling the military forces left there.

In 324 BCE, Alexander staged another kind of political relationship at Susa, an Achaemenid capital in what is now southwestern Iran. He and ninety-one of his companions married Iranian noblewomen in a single ceremony. Historian Pierre Briant describes the spectacle as designed to make an impression. It connected Macedonian officers to Iranian aristocratic families at court, while Alexander’s continued reliance on Iranian officials and soldiers addressed immediate governing and military needs.

After Alexander died in Babylon in 323 BCE, his commanders, known as the Diadochi or successors, fought over his territories. Seleucus I (r. 305–281 BCE), one of those commanders, received Babylonia and built a kingdom from it, expanding from the eastern provinces westward. Seleucid kings used satraps to collect tribute, raise troops and keep order. Antiochus I (r. 281–261 BCE) had governed the eastern provinces, called the Upper Satrapies, alongside his father from 292 BCE; the court rebuilt Bactra, now Balkh in northern Afghanistan, as an eastern capital. Royal companions, known as the Friends of the King, also held offices and commands and received estates and favors.

From administrative Aramaic to Iranian scripts

Administrative Aramaic was the language used by the Achaemenid royal chancery, the office that handled government correspondence and records. Provincial scribes developed local spelling and writing customs. After the empire fell, these forms were adapted to write several Iranian languages: Middle Persian, used in Sasanian Iran; Parthian, used in the kingdom of Parthia; and the Central Asian languages Sogdian and Chorasmian. The languages were Iranian, while the scripts descended from Aramaic.

In Middle Persian and Parthian writing, scribes sometimes kept an Aramaic word as a written sign but read it as its Iranian equivalent. This practice is called a heterogram. Later, scribes joined letters into cursive combinations. Book Pahlavi, the cursive book script used for Middle Persian texts, developed letter forms that could look alike, so readers relied on the surrounding word and sentence.

At Nisa, a Parthian royal center in modern Turkmenistan near Ashgabat, the first-century BCE wine-storehouse archive includes clay potsherds with short delivery notes. The royal foundation managed farms and vineyards; scribes recorded incoming wine on these temporary tallies, then transferred the contents to a more durable running account, probably on parchment.

Royal places used by later rulers and worshippers

At Naqsh-e Rustam, about six kilometres northwest of Persepolis in Iran’s Fars region, Achaemenid kings cut tombs high into the cliff. Centuries later, Sasanian kings carved royal scenes on the same rock face. Ardashir I (224–241 CE) appears receiving a diadem, the band that marked kingship, from the god Ohrmazd; an inscription identifies both figures. Shapur I (r. 242–273 CE) commissioned victory reliefs celebrating campaigns against Rome. The repeated use of this prominent cliff placed Sasanian images of kingship beside the older royal tombs.

At Pasargadae, the stone building identified as Cyrus’s tomb was incorporated into a mosque during the reign of Saʿd b. Zangi, a Salghurid ruler of Fars (1203–1231). Builders inserted a mihrab, the niche marking the direction of prayer, into the tomb chamber’s southwest wall. By 1474, Venetian traveler Giosafat Barbaro recorded the local name “tomb of the Mother of Solomon.”

Recovering the Achaemenid past

Copies of royal inscriptions helped scholars decipher Old Persian cuneiform, the wedge-marked script carved on Achaemenid monuments. Carsten Niebuhr published accurate copies from Persepolis in 1778. Georg Friedrich Grotefend compared repeated royal names and titles, inferring the approximate sounds of about ten signs in 1802. In the nineteenth century, Henry Rawlinson published and translated the large three-language Behistun inscription in western Iran; its Old Persian, Elamite and Babylonian versions helped scholars compare the three scripts. At Pasargadae, Robert Ker Porter sent Grotefend a drawing of a trilingual inscription. Grotefend recognized the name Cyrus, prompting Porter to identify the tomb with the ancient king, though scholars debated the site’s identity for decades; consensus formed in the late nineteenth century, and Ernst Herzfeld’s 1908 dissertation established the identification.

Modern archaeology also identified the buildings and landscape at Pasargadae. Ernst Herzfeld began excavating there in 1923 and prepared a site plan during a four-week season in 1928. David Stronach’s excavations from 1961 to 1963 examined the palace plans, early stone architecture and garden channels. Later magnetic surveys mapped wide areas aligned with the royal garden and adjoining palaces.
