What Was the Sasanian Empire Golden Age?

The Sasanian golden age is generally dated to the reign of Khosrow I Anushirvan (531–579 CE), with the reign of his grandson Khosrow II (590–628) sometimes counted as a late phase. The phrase is a modern construction, and it requires a little care. The Sasanian state, like every pre-modern state, was a mixture of brilliance and brutality: the suppression of the Mazdakite movement in 528/529 involved substantial violence, the wars with Byzantium were long and costly, and the executions of religious dissenters (the Mazdakites under Khosrow I, the Manichaeans under Bahram I) are part of the picture. The “golden age” is, however, a useful shorthand for the remarkable flourishing of culture, learning, and political power that characterised the Sasanian state in the sixth century CE.

The standard treatment is Touraj Daryaee’s Sasanian Persia (2009), with Matthew Canepa’s The Two Eyes of the Earth (2009) for the artistic aspects and James Howard-Johnston’s The Last Great War of Antiquity (2021) for the strategic context.

The reign of Khosrow I

The reign of Khosrow I is the core of the Sasanian golden age. Khosrow came to the throne in 531 CE after a long period of instability that had included the reign of his father Kavad I and the Mazdakite movement. The epithet Anushirvan, “of immortal soul,” was added to his name after his death and became an enduring phrase in Iranian history; Khosrow became the model of the just king in later Sasanian, Arabic, and Persian literature, and the Shahnameh of Firdowsi treats him as the great example of Iranian kingship.

Khosrow suppressed the Mazdakite movement in 528/529 CE. He used the suppression as a pretext to strengthen the power of the crown, reform the tax and administrative systems, and launch a series of wars against the enemies of the Sasanian state. The reign of Khosrow saw the defeat of the Hephthalites in the east (in a 557 CE coalition with the Göktürks), the renewal of the long struggle with Byzantium in the west, and the patronage of the Academy of Gondeshapur. The Sasanian rock reliefs at Taq-e Bostan, the Carpet of the Spring of Khosrow (probably legendary, but a fixed point of the tradition), and the great Sasanian silver plate of the sixth century are all products of his reign or its immediate aftermath.

The Academy of Gondeshapur

The Academy of Gondeshapur, founded in the third century CE in the city of Gondeshapur in Khuzistan, was the major centre of learning in the Sasanian world, and one of the great intellectual centres of late antiquity. It was a multi-religious, multi-lingual institution that brought together Greek, Syriac, Indian, and Persian scholars in a programme of translation and original research. The Academy was particularly important for medicine, astronomy, and philosophy, and it was a major channel by which Greek scientific and philosophical texts reached the Islamic world. The methods, the personnel, and the library of Gondeshapur were inherited, in significant part, by the Abbasid translation movement in Baghdad in the ninth century.

Khosrow is said to have welcomed a number of Greek philosophers who had been expelled from Athens by the Byzantine emperor Justinian in 529 CE. The seven philosophers, who were sometimes called the Hukayma in the Arabic sources, settled at Gondeshapur and were credited with translations of Greek philosophical and scientific texts into Syriac and Middle Persian. The story is treated with caution by modern scholars — the number “seven” and the name Hukayma are not securely attested, and the content of the translations is hard to determine — but it tells us that the Sasanian court was seen as a serious intellectual centre by contemporaries. Whether it was as serious as the story implies is a question that the surviving evidence does not let us answer.

The administrative reforms

Khosrow presided over a major reform of the Sasanian administrative system. The Sasanian tax system, which had been based on a complex set of local customary payments, was reformed by Khosrow on the basis of a comprehensive cadastral survey of the empire’s agricultural land, a standardisation of the tax rates, a centralised system of tax collection, and a network of state granaries. The reforms are described in detail in the Pahlavi text Matikan i Hazar Datastan (the Book of a Thousand Decisions), the most important Sasanian legal text to survive in the original. The reforms were inspired, in part, by the Byzantine tax system, and they are an important example of the long exchange of administrative ideas between the Sasanian and Byzantine empires.

Khosrow also reformed the Sasanian legal system. The Sasanian legal tradition, which was based on the Avesta and on customary law, was codified in the reign of Khosrow in a series of Pahlavi legal texts. The Dastur-namag, a legal text attributed to the reign of Khosrow, was the basis of the Sasanian legal tradition and was influential in the development of Islamic law in Iran. Khosrow also reorganised the Sasanian heavy cavalry (savārān) on the basis of land grants to noble families, who were required to maintain a fixed number of cataphracts in return — the Sasanian predecessor of the Islamic iqta` system.

Cultural achievements

The Sasanian golden age saw a major flowering of Sasanian art, architecture, and literature. The famous Carpet of the Spring of Khosrow — a great silk and gold carpet that depicted a garden in full bloom, and that was later, according to the Arabic sources, cut up and sold as booty by the Arab conquerors after the fall of Ctesiphon in 637 CE — is probably legendary, but it is a fixed point of the Sasanian cultural tradition. The Sasanian rock reliefs at Taq-e Bostan, depicting the king in investiture and hunting scenes, are a product of the sixth century. The Sasanian silver plate of the sixth century, with its sophisticated combination of Greek, Iranian, and Central Asian motifs, was widely imitated in the Byzantine, Islamic, and medieval European worlds — the Hermitage plate collection, the Metropolitan’s holdings, and the British Museum’s Sasanian silver are the principal museum collections.

The Sasanian golden age was also a major period of literary activity. The Kar-Namag i Ardashir, the Bundahishn, the Denkard, and many other Pahlavi texts were compiled or expanded in the sixth century. The Sasanian court poets, the gosan, were active at the court of Khosrow, and the Sasanian court was a major centre of poetic and musical activity. The Sasanian tradition of music, in particular, was highly developed, and the Sasanian court musicians were famous across the ancient world — the names of Barbod, Nakisa, and Sarkash are preserved mainly in later Arabic and Persian sources, but the underlying reality of a major musical culture at the Sasanian court is not in doubt.

The golden age in perspective

The Sasanian golden age of the sixth century was a major period in the history of pre-Islamic Iran. The military successes, the administrative reforms, the cultural achievements, and the intellectual ferment of the reign of Khosrow I shaped the political, religious, and intellectual traditions of the Islamic world, and the memory of the Sasanian golden age has been preserved in a rich body of Greek, Syriac, Armenian, Arabic, and Middle Persian sources.

The phrase “golden age” is, on closer inspection, a useful shorthand for a particular convergence of military success, administrative capacity, cultural production, and intellectual ferment. The Sasanian state of the sixth century had all four. The Sasanian state of the seventh century, after the long war with Byzantium and the civil wars of the 620s, had none. The golden age was, in the historical sense, a period rather than a permanent condition. The Sasanian state recovered, briefly, under Khosrow II in the early seventh century, and then collapsed. The golden age of the sixth century is, in the memory of Iranian history, the moment to which later Persian literature kept returning.
