Kavad I ( ; 473 – 13 September 531) was the Sasanian King of Kings of Iran from 488 to 531, including a two- or three-year interruption. A son of Peroz I (), he was crowned by the nobles to replace his deposed and unpopular uncle Balash ().
Inheriting a declining empire where the authority and status of the Sasanian kings had largely weakened, Kavad tried to reorganize his empire by introducing many reforms whose implementation was completed by his son and successor, Khosrow I. They were made possible by Kavad's use of the Mazdakite preacher Mazdak, leading to a social revolution that weakened the authority of the nobility and the clergy. Because of this, and the execution of the powerful king-maker Sukhra, Kavad was deposed and imprisoned in the Castle of Oblivion. He was replaced by his brother Jamasp. However, with the aid of his sister and an officer named Siyawush, Kavad and some of his followers fled east to the territory of the Hephthalite king, who provided him with an army. This enabled Kavad to restore himself to the throne in 498/9.
The empire had been bankrupted by his absence and Kavad asked the Byzantine emperor Anastasius I for assistance. The Byzantines had originally paid the Iranians voluntarily to maintain the defense of the Caucasus against attacks from the north. Anastasius refused to help, which led Kavad to invade his domains, thus starting the Anastasian War. Kavad first seized Theodosiopolis and Martyropolis, and then Amida after holding the city under siege for three months. The two empires made peace in 506, with the Byzantines agreeing to pay the Sasanians for the maintenance of the fortifications in the Caucasus in return for Amida. Around this time, Kavad also fought a lengthy war against his former allies, the Hephthalites; by 513 he had re-taken the region of Khorasan from them.
In 528, the Iberian War erupted between the Sasanians and Byzantines in what is now eastern Georgia because the Byzantines refused to acknowledge Khosrow as Kavad's heir and because of a dispute over Lazica. Although Kavad's forces suffered two notable losses at the battles of Dara and Satala, the war was largely indecisive, with both sides suffering heavy losses. In 531, while the Sasanian army was besieging Martyropolis, Kavad died from an illness. He was succeeded by Khosrow I, who inherited a reinvigorated and mighty empire equal to that of the Byzantines.
Because of the many challenges and issues Kavad successfully overcame, he is considered one of the most effective and successful kings to rule the Sasanian Empire. In the words of the Iranologist Nikolaus Schindel, he was "a genius in his own right, even if of a somewhat Machiavellian type."
Name Due to increased Sasanian interest in Kayanian history, Kavad was named after the mythological Kayanian king Kavi Kavata. The name is transliterated in Greek as Kabates, Chü-he-to in Chinese, and in Arabic. (also with a ghayn instead of qaf) is the form used in New Persian.
Background and state of Sasanian Iran
The son of the Sasanian shah Peroz I (), Kavad was born in 473. The Sasanian family had been the monarchs of Iran since 224 after the triumph of the first Sasanian shah Ardashir I () over the Parthian (Arsacid) Empire. Although Iranian society was greatly militarised and its elite designated themselves as a "warrior nobility" (arteshtaran), it still had a significantly smaller population, was more impoverished, and was a less centralized state compared to the Roman Empire. As a result, the Sasanian shahs had access to fewer full-time fighters, and depended on recruits from the nobility instead. Some exceptions were the royal cavalry bodyguard, garrison soldiers, and units recruited from places outside Iran.
The bulk of the high nobility included the powerful Parthian noble families (known as the wuzurgan) that were centered on the Iranian plateau. They served as the backbone of the Sasanian "feudal" army and were largely autonomous. The Sasanian shahs had noticeably little control over the wuzurgan; attempts to restrict their self-determination usually resulted in the murder of the shah. Ultimately, the Parthian nobility worked for the Sasanian shah for personal benefit, personal oath, and, conceivably, a common awareness of the "Aryan" (Iranian) kinship they shared with their Persian overlords.
Another vital component of the army was the Armenian cavalry, which was recruited from outside the ranks of the Parthian wuzurgan. However, the revolt of Armenia in 451 and the loss of its cavalry had weakened the Sasanians' attempts to keep the Hunnic tribes (i.e., the Hephthalites, Kidarites, Chionites and Alkhans) of the northeastern border in check. Indeed, Kavad's grandfather Yazdegerd II () had managed to hold off the Kidarites during his wars against them, which had occupied him throughout most of his reign. Now, however, Sasanian authority in Central Asia began to decay.
First in 474 and again in the late 470s/early 480s, Peroz was defeated and captured by the Hephthalites. In his second defeat, he offered to pay thirty mule packs of silver drachms in ransom, but could only pay twenty. Unable to pay the other ten, he sent Kavad in 482 as a hostage to the Hephthalite court until he could pay the rest. He eventually managed to gain the ten mule packs of silver by imposing a poll tax on his subjects, and thus secured the release of Kavad before he mounted his third campaign in 484. There, Peroz was defeated and killed by a Hephthalite army, possibly near Balkh. His army was completely destroyed, and his body was never found. Four of his sons and brothers had also died. The main Sasanian cities of the eastern region of Khorasan−Nishapur, Herat and Marw were now under Hephthalite rule.
Sukhra, a member of the Parthian House of Karen, one of the Seven Great Houses of Iran, quickly raised a new force and stopped the Hephthalites from achieving further success. Peroz's brother, Balash, was elected as shah by the Iranian magnates, most notably Sukhra and the Mihranid general Shapur Mihran. However, Balash proved unpopular among the nobility and clergy who had him blinded and deposed after just four years in 488. Sukhra, who had played a key role in Balash's deposition, appointed Kavad as the new shah of Iran. According to Miskawayh (), Sukhra was Kavad's maternal uncle.
First reign Accession and conditions of the empire
Kavad ascended the throne in 488 at the age of 15. His youth is emphasized on his coins, which show him with short whiskers. He inherited an empire that had reached its lowest ebb. The nobility and clergy exerted great influence and authority over the nation, and were able to act as king-makers, as seen by their choice to depose Balash. Economically, the empire was not doing well either, the result of drought, famine, and the crushing defeats delivered by the Hephthalites. They had not only seized large parts of its eastern provinces, but had also forced the Sasanians to pay vast amounts of tribute to them, which had depleted the royal treasury of the shah. Rebellions were occurring in the western provinces including Armenia and Iberia. Simultaneously, the country's peasant class was growing more and more uneasy and alienated from the elite.
Conflict with Sukhra over the empire
The young and inexperienced Kavad was tutored by Sukhra during his first five years as shah. During this period, Kavad was a mere figurehead, whilst Sukhra was the de facto ruler of the empire. This is emphasized by al-Tabari, who states that Sukhra "was in charge of government of the kingdom and the management of affairs ... [T]he people came to Sukhra and undertook all their dealings with him, treating Kavad as a person of no importance and regarding his commands with contempt." Numerous regions and the representatives of the elite paid tribute to Sukhra, not to Kavad. Sukhra controlled the royal treasury and the Iranian military. In 493, Kavad, having reached adulthood, wanted to put an end to Sukhra's dominance, and had him exiled to his native Shiraz in southwestern Iran. Even in exile, however, Sukhra was in control of everything except the kingly crown. He bragged about having put Kavad on the throne.
Alarmed by the thought that Sukhra might rebel, Kavad wanted to get rid of him completely. He lacked the manpower to do so, however, as the army was controlled by Sukhra and the Sasanians relied mainly on the military of the Seven Great Houses of Iran. He found his solution in Shapur of Ray, a powerful nobleman from the House of Mihran, and a resolute opponent of Sukhra. Shapur, at the head of an army of his own men and disgruntled nobles, marched to Shiraz, defeated Sukhra's forces, and imprisoned him in the Sasanian capital of Ctesiphon. Even in prison, Sukhra was considered too powerful and was executed. This caused displeasure among some prominent members of the nobility, weakening Kavad's status as shah. It also marked the temporary loss of authority of the House of Karen, whose members were exiled to the regions of Tabaristan and Zabulistan, which were away from the Sasanian court in Ctesiphon.
The Mazdakite movement and Kavad I's deposition
According to classical sources, not long after Sukhra's execution, a mobad (priest) named Mazdak caught Kavad's attention. Mazdak was the chief representative of a religious and philosophical movement called Mazdakism. Not only did it consist of theological teachings, but it also advocated for political and social reforms that would impact the nobility and clergy.
The Mazdak movement was nonviolent and called for the sharing of wealth, women and property, an archaic form of communism. According to modern historians Touraj Daryaee and Matthew Canepa, 'sharing women' was most likely an overstatement and defamation deriving from Mazdak's decree that loosened marriage laws to help the lower classes. Powerful families saw this as a tactic to weaken their lineage and advantages, which was most likely the case. Kavad used the movement as a political tool to curb the power of the nobility and clergy. Royal granaries were distributed, and land was shared among the lower classes.
The historicity of the persona of Mazdak has been questioned. He may have been a fabrication to take the blame away from Kavad. Contemporary historians, including Procopius and Joshua the Stylite make no mention of Mazdak, naming Kavad as the figure behind the movement. Mention of Mazdak only emerges in later Middle Persian Zoroastrian documents, namely the Bundahishn, the Denkard, and the Zand-i Wahman yasn. Later Islamic-era sources, particularly al-Tabari, also mention Mazdak. These later writings were perhaps corrupted by Iranian oral folklore, given that blame put on Mazdak for the redistribution of aristocratic properties to the people, is a topic repeated in Iranian oral history. Other 'villains' in pre-Islamic Iranian history, namely Gaumata in the Behistun Inscription of the Achaemenid king Darius the Great () and Wahnam in the Paikuli inscription of the Sasanian king Narseh (), are frequently accused of similar misdeeds.
The nobility deposed Kavad in 496 for his support of the Mazdakites and his execution of Sukhra. They installed his more impressionable brother Jamasp on the throne.
