Sassanid Legacy and Influence

After Arab armies conquered the Sassanid Empire, new rulers took over cities, mints and tax districts where local officials, craftsmen and readers already had established skills. Those people and practices remained useful, but they acquired new patrons and purposes. Silver coins took on Arabic religious statements, local landholders collected revenue for Arab governors, and Middle Persian court literature entered Arabic through translators who reshaped it for new audiences. Later rulers across the region also commissioned buildings and textiles that transformed Sassanid forms.

Coins under new authorities

The silver drahm shows how a working institution could continue while its political message changed. After Arab forces captured an Iranian city, its mint could keep producing coins in the familiar Sassanid format. A drahm showed a crowned ruler in profile on one side and a Zoroastrian fire altar with attendants on the other. Pahlavi inscriptions named rulers or officials, while the coin also marked its mint and year. The circulation of silver and the expertise of local engravers and mint workers made this established type practical for the new administration.

After Yazdegerd III died in 651, some issues began to mark Arab authority. In 670–675, when the former Sassanid lands were reunited under a single Arab governor, the name of an Arab official replaced that of Khosrow II in Pahlavi script. Arabic religious phrases appeared around the coin’s edge. During the 690s, some transitional drahms went further: one issue replaced the Zoroastrian altar with a praying figure. In 698–699, Arabic-only silver dirhams appeared at Damascus and nearly thirty eastern mints. Sassanid-type coins continued in Fars, in southwestern Iran, for several years, with the last regular Arab-Sassanid drahm dated 704–705. The change therefore moved through regional mints over time.

Coins also crossed political frontiers. In Khorasan and eastern Iran, some drahms received small counterstamps in Bactrian, a local language used beyond the Arab-held frontier. A counterstamp was an added mark that revalidated a coin for circulation. Its use shows how neighboring authorities and traders could make existing silver serve local exchange, even as Arab governors and caliphs changed the inscriptions on new issues.

Landholders and fiscal practice

Conquest also relied on local people who knew the land and its obligations. A dehqān was a member of the landed gentry, often responsible for local affairs and tax collection. In many Persian towns and districts, agreements made during surrender specified a fixed tribute, goods or services in return for peace, protection and religious freedom. Local officials or dehqāns collected what the agreement required, and Arab governors received the money from them. The new administration therefore depended on people who already knew cultivators, fields and local settlements.

In Khorasan, the broad eastern region that included northeastern Iran and parts of Central Asia and Afghanistan, dehqāns remained answerable for the assessed total as collection shifted from a lump sum of tribute toward taxes assessed on land. This arrangement linked local knowledge to the governors’ revenue needs. The registers and tax language did not change at the same pace everywhere: Khorasan’s records switched to Arabic in 739, later than in Iraq. The shift to Arabic changed the working language of tax records while local intermediaries continued to handle assessment and collection.

Court images and portable arts

Royal imagery traveled into Islamic settings with new meanings. Mosaics commissioned for Jerusalem’s Dome of the Rock in 691 include Sassanid crowns. In a monument built under the Umayyad caliph Abd al-Malik, the crowns lent familiar royal symbols a new setting. Placed among the religious monument’s mosaics, they gave the new caliphate a visual language of imperial splendor.

Silk offers a more portable route for motifs to move between courts. The Metropolitan Museum of Art holds an eighth-century silk fragment, attributed to Egypt or Syria, showing a mounted hunter aiming at a panther within a roundel. The museum traces the horse-and-bow hunting motif to Sassanid Iran and notes its adaptation in Byzantine heraldry. The fragment also carries the Arabic phrase bismillah, “in the name of God,” placing the textile in an early Islamic context. Its imagery combines a Sassanid-derived hunting scene, Byzantine-related textile traditions and an Arabic inscription. The design could be woven far from Sassanid Iran and used within a new courtly and religious setting.

Translation and royal memory

Translators carried court writing into new languages and changed how it worked. Ibn al-Muqaffa, a Persian-born secretary in the Abbasid chancery, the bureau that handled official correspondence and records, and a major Arabic prose writer, lived around 721–757. He translated Kalila and Dimna from a lost Middle Persian version. The stories, largely rooted in Indian fables, use animal characters to discuss conduct and power. Ibn al-Muqaffa introduced the Arabic work with his own prologue and may have added stories; scholars describe his rendering as idiomatic rather than word-for-word. In Abbasid court circles it offered examples of how people could pursue political and social success.

The Arabic version created a new path for the stories. In the tenth century, the Samanids ruled from Bukhara across Khorasan and much of Central Asia. Their vizier Balʿami, a senior minister, prepared a Persian prose version for ruler Nasr II, and the poet Rudaki made a verse version from it. Later Persian writers returned to the Arabic text and produced their own adaptations. Between the eleventh and thirteenth centuries, versions of Ibn al-Muqaffa’s Arabic text also appeared in Greek, Hebrew and Old Spanish. The fables thus moved from Indian and Middle Persian materials into Arabic court prose, then into Persian and Mediterranean literary settings, with each translator selecting a style and audience.

Royal history followed a related but less direct route. Ibn al-Muqaffa is thought to have adapted the late Sassanid Xwadāy-nāmag, or “Book of Kings,” into Arabic. The chronicle presented the stories and reigns of pre-Islamic Persian rulers; Ibn al-Muqaffa modified some passages and omitted others, possibly to make them intelligible to Arab Muslim readers. His Arabic version is lost, and later authors encountered royal history through collections and traditions that had already changed.

Local landed families helped transmit that memory. In 957, the compiler Abu Mansur Maʿmari gathered dehqāns from several cities in Khorasan while assembling a Persian prose book of kings. Ferdowsi later drew on this work and cited dehqāns as sources for episodes in the Shahnameh, completed around 1010. The epic gave earlier Iranian rulers and heroes a new poetic form in Islamic-era Persian. Its connection to Sassanid-era royal traditions ran through later compilers, oral accounts and literary choices.

Religious texts and medical learning

Zoroastrian clergy continued writing and copying religious works in Middle Persian after the conquest. Many surviving Pahlavi compilations were recorded in the ninth and tenth centuries and preserve older material; Book VIII of the Dēnkard summarizes the Sassanid Avesta and its commentary. This was a way to keep religious teaching and knowledge of the older canon available to readers who no longer knew Avestan well.

In Gondeshapur, Syriac remained a language for medical reading and writing into the early Islamic centuries. The physician Jewarjis headed a hospital there in 765, and his descendants continued to read Syriac medical books as the family entered Arabic-speaking Islamic society. In the ninth century, Ḥunayn ibn Isḥāq and his collaborators translated Galen’s works from Greek into Syriac and Arabic, carrying medical texts through these languages to new readers.

Buildings and later uses

Architectural forms also entered new commissions through builders’ knowledge and regional practice. An iwan is a vaulted hall open at one end; in Sassanid palaces it could face a domed chamber. A dome could rest on squinches, small arches spanning the corners of a square room to support a circular base above it. Abbasid rulers used axial iwans in front of domed chambers in the palace at Marv, in present-day Turkmenistan, dated to 747–755, and in major buildings at Samarra in Iraq. The spatial combination recurred in Abbasid palaces, although its use could differ from that of Sassanid buildings. At the eighth-century mosque known as the Tari-khana at Damghan in Iran, a three-aisled entrance hall has brick piers and tunnel vaults resembling features in an earlier Sassanid building nearby. The comparison shows building solutions used in both periods within different architectural settings.

Some cities also reused older regional plans. Baghdad in Iraq, founded by the Abbasid caliph al-Mansur in 762, was laid out as a circular city, a form also found in major Parthian and Sassanid towns. The Sassanid sanctuary at Takht-e Soleyman in northwestern Iran was partly rebuilt in the thirteenth century under the Ilkhanids. At Ctesiphon, near modern Baghdad in Iraq, the surviving great arch preserves a visible remnant of Sassanid imperial architecture.
