Sassanids
History
The Sasanian or Sassanid Empire, known to its inhabitants as Eranshahr, was the last Iranian empire before the rise of Islam, ruled by and named after the Sasanian dynasty from 224 to 651. The Sassanid Empire, which succeeded the Parthian Empire, was recognized as one of the leading world powers alongside its neighboring arch-rival the Roman-Byzantine Empire, for a period of more than 400 years. The Sasanian Empire was founded by Ardashir I, after the fall of the Parthian Empire and the defeat of the last Arsacid king, Artabanus V. The Sasanian Empire during Late Antiquity is considered to have been one of Iran's most important and influential historical periods, and constituted the last great Iranian empire before the Muslim conquest and the adoption of Islam. In many ways, the Sasanian period witnessed the peak of ancient Iranian civilization. Persia influenced Roman culture considerably during the Sasanian period. The Sasanians' cultural influence extended far beyond the empire's territorial borders, reaching as far as Western Europe, Africa, China and India. It played a prominent role in the formation of both European and Asian medieval art. Much of what later became known as Islamic culture in art, architecture, music and other subject matter was transferred from the Sasanians throughout the Muslim world.
Geography and Climate
At its greatest extent, the Sasanian Empire encompassed all of today's Iran, Iraq, Eastern Arabia, the Levant, the Caucasus, Egypt, large parts of Turkey, much of Central Asia, Yemen and Pakistan. Iran has a hot, dry climate characterized by long, hot, dry summers and short, cool winters. The climate is influenced by Iran's location between the subtropical aridity of the Arabian desert areas and the subtropical humidity of the eastern Mediterranean area. Iraq has a hot, dry climate characterized by long, hot, dry summers and short, cool winters.
Origins and Founding
Conflicting accounts shroud the details of the fall of the Parthian Empire and subsequent rise of the Sasanian Empire in mystery. The Sassanid Empire was established in Estakhr by Ardashir I. Papak was originally the ruler of a region called Khir. However, by the year 200, he managed to overthrow Gochihr, and appoint himself as the new ruler of the Bazrangids. His mother, Rodhagh, was the daughter of the provincial governor of Pars. Papak and his eldest son Shapur managed to expand their power over all of Pars. The subsequent events are unclear, due to the elusive nature of the sources. It is certain, however, that following the death of Papak, Ardashir who at the time was the governor of Darabgird, got involved in a power struggle of his own with his elder brother Shapur. Sources reveal that Shapur, leaving for a meeting with his brother, was killed when the roof of a building collapsed on him. By the year 208, over the protests of his other brothers who were put to death, Ardashir declared himself ruler of Pars. Once Ardashir was appointed shahanshah, he moved his capital further to the south of Pars and founded Ardashir-Khwarrah (modern day Firuzabad). The city, well supported by high mountains and easily defendable through narrow passes, became the center of Ardashir's efforts to gain more power. The city was surrounded by a high, circular wall, probably copied from that of Darabgird, and on the north-side included a large palace, remains of which still survive today. After establishing his rule over Pars, Ardashir I rapidly extended his territory, demanding fealty from the local princes of Fars, and gaining control over the neighboring provinces of Kerman, Isfahan, Susiana and Mesene. This expansion quickly came to the attention of Artabanus V, the Parthian king, who initially ordered the governor of Khuzestan to wage war against Ardashir in 224, but the battles were victories for Ardashir. In a second attempt to destroy Ardashir, Artabanus V himself met Ardashir in battle at Hormozgan, where Artabanus V met his death. Following the death of the Parthian ruler, Ardashir I went on to invade the western provinces of the now defunct Parthian Empire. At that time the Arsacid dynasty was divided between supporters of Artabanus V and Vologases VI, which probably allowed Ardashir to consolidate his authority in the south with little or no interference from the Parthians. Ardashir was aided by the geography of the province of Fars, which was separated from the rest of Iran. Crowned in 224 at Ctesiphon as the sole ruler of Persia, Ardashir took the title shahanshah, or "King of Kings", bringing the 400-year-old Parthian Empire to an end, and beginning four centuries of Sassanid rule.
Early Sassanid Period: Conflicts with Rome
In the next few years, local rebellions would form around the empire. Nonetheless, Ardashir I further expanded his new empire to the east and northwest, conquering the provinces of Sistan, Gorgan, Khorasan, Margiana, Balkh and Chorasmia. He also added Bahrain and Mosul to Sassanid's possessions. Later Sassanid inscriptions also claim the submission of the Kings of Kushan, Turan and Mekran to Ardashir, although based on numismatic evidence, it is more likely that these actually submitted to Ardashir's son, the future Shapur I. In the west, assaults against Hatra, Armenia and Adiabene met with less success. In 230, he raided deep into Roman territory, and a Roman counter-offensive two years later ended inconclusively, although the Roman emperor, Alexander Severus, celebrated a triumph in Rome. Ardashir I's son Shapur I continued the expansion of the empire, conquering Bactria and the western portion of the Kushan Empire, while leading several campaigns against Rome. Invading Roman Mesopotamia, Shapur I captured Carrhae and Nisibis, but in 243 the Roman general Timesitheus defeated the Persians at Rhesaina and regained the lost territories. The emperor Gordian III's (238244) subsequent advance down the Euphrates was defeated at Meshike (244), leading to Gordian's murder by his own troops and enabling Shapur to conclude a highly advantageous peace treaty with the new emperor Philip the Arab, by which he secured the immediate payment of 500,000 denarii and further annual payments. Shapur soon resumed the war, defeated the Romans at Barbalissos (253), and then probably took and plundered Antioch. Roman counter-attacks under the emperor Valerian ended in disaster when the Roman army was defeated and besieged at Edessa, and Valerian was captured by Shapur, remaining his prisoner for the rest of his life. Shapur celebrated his victory by carving the impressive rock reliefs in Naqsh-e Rostam and Bishapur, as well as a monumental inscription in Persian and Greek in the vicinity of Persepolis. He exploited his success by advancing into Anatolia (260), but withdrew in disarray after defeats at the hands of the Romans and their Palmyrene ally Odaenathus, suffering the capture of his harem and the loss of all the Roman territories he had occupied. Shapur had intensive development plans. He ordered the construction of the first dam bridge in Iran and founded many cities, some settled in part by emigrants from the Roman territories, including Christians who could exercise their faith freely under Sassanid rule. Two cities, Bishapur and Nishapur, are named after him. He particularly favored Manichaeism, protected Mani (who dedicated one of his books, the Shabuhragan, to him) and sent many Manichaean missionaries abroad. Later kings reversed Shapur's policy of religious tolerance. Under pressure from Zoroastrian Magi and influenced by the high-priest Kartir, Bahram I killed Mani and persecuted his followers. Bahram II was, like his father, amenable to the wishes of the Zoroastrian priesthood. During his reign, the Sassanid capital Ctesiphon was sacked by the Romans under Emperor Carus, and most of Armenia, after half a century of Persian rule, was ceded to Diocletian.
Succeeding Bahram III (who ruled briefly in 293), Narseh embarked on another war with the Romans. After an early success against the Emperor Galerius near Callinicum on the Euphrates in 296, Narseh was decisively defeated. Galerius had been reinforced, probably in the spring of 298, by a new contingent collected from the empire's Danubian holdings. Narseh did not advance from Armenia and Mesopotamia, leaving Galerius to lead the offensive in 298 with an attack on northern Mesopotamia via Armenia. Narseh retreated to Armenia to fight Galerius' force, to Narseh's disadvantage: the rugged Armenian terrain was favorable to Roman infantry, but not to Sassanid cavalry. Local aid gave Galerius the advantage of surprise over the Persian forces, and, in two successive battles, Galerius secured victories over Narseh. During the second encounter, Roman forces seized Narseh's camp, his treasury, his harem, and his wife along with it. Galerius advanced into Media and Adiabene, winning successive victories, most prominently near Erzurum, and securing Nisibis (Nusaybin, Turkey) before October 1, 298. He moved down the Tigris, taking Ctesiphon. Narseh had previously sent an ambassador to Galerius to plead for the return of his wives and children. Peace negotiations began in the spring of 299, with both Diocletian and Galerius presiding. The conditions of the peace were heavy: Persia would give up territory to Rome, making the Tigris the boundary between the two empires. Further terms specified that Armenia was returned to Roman domination, with the fort of Ziatha as its border; Caucasian Iberia would pay allegiance to Rome under a Roman appointee; Nisibis, now under Roman rule, would become the sole conduit for trade between Persia and Rome; and Rome would exercise control over the five satrapies between the Tigris and Armenia: Ingilene, Sophanene (Sophene), Arzanene (Aghdznik), Corduene, and Zabdicene (near modern Hakkâri, Turkey).The Sassanids ceded five provinces west of the Tigris, and agreed not to interfere in the affairs of Armenia and Georgia. In the aftermath of this defeat, Narseh gave up the throne and died a year later, leaving the Sassanid throne to his son, Hormizd II. Unrest spread throughout the land, and while Hormizd II suppressed revolts in Sakastan and Kushan, he was unable to control the nobles and was subsequently killed by Bedouins in a hunting trip in 309.
First Golden Era: Reign of Shapur II
Following Hormizd II's death, Arabs started to ravage and plunder the eastern cities of the empire, even attacking the province of Fars, the birthplace of the Sassanid kings. Meanwhile, Persian nobles killed Hormizd II's eldest son, blinded the second, and imprisoned the third (who later escaped to Roman territory). The throne was reserved for Shapur II, the unborn child of one of Hormizd II's wives who was crowned in utero: the crown was placed upon his mother's stomach. During his youth, the empire was controlled by his mother and the nobles. Upon Shapur II's coming of age, he assumed power and quickly proved to be an active and effective ruler. Shapur II first led his small but disciplined army south against the Arabs, whom he defeated, securing the southern areas of the empire. He then started his first campaign against the Romans in the west, where Persian forces won a series of battles but were unable to make territorial gains due to the failure of repeated sieges of the key frontier city of Nisibis, and Roman success in retaking the cities of Singara and Amida, after they had fallen to the Persians. These campaigns were halted by nomadic raids along the eastern borders of the empire, which threatened Transoxiana, a strategically critical area for control of the Silk Road. Shapur therefore marched east toward Transoxiana to meet the eastern nomads, leaving his local commanders to mount nuisance raids on the Romans. He crushed the Central Asian tribes, and annexed the area as a new province. He completed the conquest of the area now known as Afghanistan. Cultural expansion followed this victory, and Sassanid art penetrated Turkestan, reaching as far as China. Shapur, along with the nomad King Grumbates, started his second campaign against the Romans in 359 and soon succeeded in taking Singara and Amida again. In response, the Roman emperor Julian struck deep into Persian territory and defeated Shapur's forces at Ctesiphon. He failed to take the capital, however, and was killed while trying to retreat to Roman territory. His successor Jovian, trapped on the east bank of the Tigris, had to hand over all the provinces the Persians had ceded to Rome in 298, as well as Nisibis and Singara, to secure safe passage for his army out of Persia. Shapur II pursued a harsh religious policy. Under his reign, the collection of the Avesta, the sacred texts of Zoroastrianism, was completed, heresy and apostasy were punished, and Christians were persecuted. The latter was a reaction against the Christianization of the Roman Empire by Constantine the Great. Shapur II, like Shapur I, was amicable towards Jews, who lived in relative freedom and gained many advantages in his period. At the time of Shapur's death, the Persian Empire was stronger than ever, with its enemies to the east pacified and Armenia under Persian control.
Intermediate Era
From Shapur II's death until Kavadh I's first coronation, there was a largely peaceful period with the Romans (by this time the Eastern Roman or Byzantine Empire), interrupted only by two brief wars, the first in 421422 and the second in 440. Throughout this era, Sassanid religious policy differed dramatically from king to king. Despite a series of weak leaders, the administrative system established during Shapur II's reign remained strong, and the empire continued to function effectively. After Shapur II died in 379, he left a powerful empire to his half-brother Ardashir II (379383; son of Vahram of Kushan) and his son Shapur III (383388), neither of whom demonstrated his predecessor's talent. Ardashir II, who was raised as the "half-brother" of the emperor, failed to fill his brother's shoes, and Shapur III was too much of a melancholy character to achieve anything. Bahram IV (388399), although not as inactive as his father, still failed to achieve anything important for the empire. During this time Armenia was divided by treaty between the Roman and Sassanid empires. The Sassanids reestablished their rule over Greater Armenia, while the Byzantine Empire held a small portion of western Armenia. Bahram IV's son Yazdegerd I (399421) is often compared to Constantine I. Like him, he was powerful both physically and diplomatically. Much like his Roman counterpart, Yazdegerd I was opportunistic. Like Constantine the Great, Yazdegerd I practiced religious tolerance and provided freedom for the rise of religious minorities. He stopped the persecution against the Christians and even punished nobles and priests who persecuted them. His reign marked a relatively peaceful era. He made lasting peace with the Romans and even took the young Theodosius II (408450) under his guardianship. Yazdegerd I's successor was his son Bahram V (421438), one of the most well-known Sassanid kings and the hero of many myths. These myths persisted even after the destruction of the Sassanid empire by the Arabs. Bahram V, better known as Bahram-e Gur, gained the crown after Yazdegerd I's sudden death (or assassination) against the opposition of the grandees with the help of al-Mundhir, the Arabic dynast of al-Hirah. Bahram V's mother was Shushandukht, the daughter of the Jewish Exilarch. In 427, he crushed an invasion in the east by the nomadic Hephthalites, extending his influence into Central Asia, where his portrait survived for centuries on the coinage of Bukhara (in modern Uzbekistan). Bahram V deposed the vassal King of the Persian part of Armenia and made it a province. During his time, the best pieces of Sassanid literature were written, notable pieces of Sassanid music were composed, and sports such as polo became royal pastimes. Bahram V's son Yazdegerd II (438457) was a just, moderate ruler, but in contrast to Yazdegerd I, practiced a harsh policy towards minority religions, particularly Christianity. However, by the 451 Battle of Avarayr, the Armenian subjects led by Vardan Mamikonian managed to affirm Armenia's right to profess Christianity freely. This was to be later confirmed by the Nvarsak Treaty (484). At the beginning of his reign, Yazdegerd II gathered a mixed army of various nations, including his Indian allies, and attacked the Eastern Roman Empire in 441, but peace was soon restored after small-scale fighting. He then gathered his forces in Nishapur in 443 and launched a prolonged campaign against the Kidarites. Finally, after a number of battles, he crushed the Kidarites and drove them out beyond the Oxus river in 450. During his eastern campaign, Yazdegerd II grew suspicious of the Christians in the army and expelled them all from the governing body and army. He then persecuted the Christians and, to a much lesser extent, the Jews. In order to reestablish Zoroastrianism in Armenia, he crushed an uprising of Armenian Christians at the Battle of Vartanantz in 451. The Armenians, however, remained primarily Christian. In his later years, he was engaged yet again with Kidarites until his death in 457. Hormizd III (457459), younger son of Yazdegerd II, ascended to the throne. During his short rule, he continually fought with his elder brother Peroz I, who had the support of nobility, and with the Hephthalites in Bactria. He was killed by his brother Peroz in 459.
In the beginning of the 5th century, the Hephthalites (White Huns), along with other nomadic groups, attacked Persia. At first Bahram V and Yazdegerd II inflicted decisive defeats against them and drove them back eastward. The Huns returned at the end of the 5th century and defeated Peroz I (457484) in 483. Following this victory, the Huns invaded and plundered parts of eastern Persia for two years. They exacted heavy tribute for some years thereafter. These attacks brought instability and chaos to the kingdom. Peroz I tried again to drive out the Hephthalites, but on the way to Herat, he and his army were trapped by the Huns in the desert; Peroz I was killed, and his army was wiped out. After this victory, the Hephthalites advanced forward to the city of Herat, throwing the empire into chaos. Eventually, a noble Iranian from the old family of Karen, Sukhra, restored some degree of order. He raised Balash, one of Peroz I's brothers, to the throne, although the Hunnic threat persisted until the reign of Khosrau I. Balash (484488) was a mild and generous monarch, who made concessions to the Christians; however, he took no action against the empire's enemies, particularly, the White Huns. Balash, after a reign of four years, was blinded and deposed (attributed to magnates), and his nephew Kavadh I was raised to the throne. Kavadh I (488531) was an energetic and reformist ruler. Kavadh I gave his support to the sect founded by Mazdak, son of Bamdad, who demanded that the rich should divide their wives and their wealth with the poor. His intention evidently was, by adopting the doctrine of the Mazdakites, to break the influence of the magnates and the growing aristocracy. These reforms led to his being deposed and imprisoned in the "Castle of Oblivion" in Susa, and his younger brother Jamasp (Zamaspes), was raised to the throne in 496. Kavadh I, however, escaped in 498 and was given refuge by the White Hun king. Djamasp was a good and kind king, and he reduced taxes in order to relieve the peasants and the poor. He was also an adherent of the mainstream Zoroastrian religion, diversions from which had cost Kavadh I his throne and freedom. His reign soon ended when Kavadh I, at the head of a large army granted to him by the Hephthalite king, returned to the empire's capital. Djamasp stepped down from his position and restored the throne to his brother. No further mention of Djamasp is made after the restoration of Kavadh I, but it is widely believed that he was treated favorably at the court of his brother.
Second Golden Era
The second golden era began after the second reign of Kavadh I. With the support of the Hephtalites, Kavadh I launched a campaign against the Romans. In 502, he took Theodosiopolis in Armenia, but lost it soon afterwards. In 503 he took Amida on the Tigris. In 504, an invasion of Armenia by the western Huns from the Caucasus led to an armistice, the return of Amida to Roman control and a peace treaty in 506. In 521/522 Kavadh lost control of Lazica, whose rulers switched their allegiance to the Romans; an attempt by the Iberians in 524/525 to do likewise triggered a war between Rome and Persia. In 527, a Roman offensive against Nisibis was repulsed and Roman efforts to fortify positions near the frontier were thwarted. In 530, Kavadh sent an army under Perozes to attack the important Roman frontier city of Dara. The army was met by the Roman general Belisarius, and though superior in numbers, was defeated at the Battle of Dara. In the same year, a second Persian army under Mihr-Mihroe was defeated at Satala by Roman forces under Sittas and Dorotheus, but in 531 a Persian army accompanied by a Lakhmid contingent under Al-Mundhir III defeated Belisarius at the Battle of Callinicum, and in 532 an "eternal" peace was concluded. Although he could not free himself from the yoke of the Hephthalites, Kavadh succeeded in restoring order in the interior and fought with general success against the Eastern Romans, founded several cities, some of which were named after him, and began to regulate the taxation and internal administration.
After Kavadh I, his son Khosrau I, also known as Anushirvan ("with the immortal soul"; ruled 531579), ascended to the throne. He is the most celebrated of the Sassanid rulers. Khosrau I is most famous for his reforms in the aging governing body of Sassanids. He introduced a rational system of taxation based upon a survey of landed possessions, which his father had begun, and he tried in every way to increase the welfare and the revenues of his empire. Previous great feudal lords fielded their own military equipment, followers, and retainers. Khosrau I developed a new force of dehqans, or "knights", paid and equipped by the central government and the bureaucracy, tying the army and bureaucracy more closely to the central government than to local lords. Emperor Justinian I (527565) paid Khosrau I 440,000 pieces of gold as a part of the "eternal peace" treaty of 532. In 540, Khosrau broke the treaty and invaded Syria, sacking Antioch and extorting large sums of money from a number of other cities. Further successes followed: in 541 Lazica defected to the Persian side, and in 542 a major Byzantine offensive in Armenia was defeated at Anglon. In the same year of 541, upon requests of the Lazic king, king Khosrau I, entered Lazica, captured the Byzantine main stronghold of Petra, and established another protectorate over the country, commencing the Lazic War. A five-year truce agreed to in 545 was interrupted in 547 when Lazica again switched sides and eventually expelled its Persian garrison with Byzantine help; the war resumed but remained confined to Lazica, which was retained by the Byzantines when peace was concluded in 562. In 565, Justinian I died and was succeeded by Justin II (565578), who resolved to stop subsidies to Arab chieftains to restrain them from raiding Byzantine territory in Syria. A year earlier, the Sassanid governor of Armenia, Chihor-Vishnasp of the Suren family, built a fire temple at Dvin near modern Yerevan, and he put to death an influential member of the Mamikonian family, touching off a revolt which led to the massacre of the Persian governor and his guard in 571, while rebellion also broke out in Iberia. Justin II took advantage of the Armenian revolt to stop his yearly payments to Khosrau I for the defense of the Caucasus passes. The Armenians were welcomed as allies, and an army was sent into Sassanid territory which besieged Nisibis in 573. However, dissension among the Byzantine generals not only led to an abandonment of the siege, but they in turn were besieged in the city of Dara, which was taken by the Persians who then ravaged Syria, causing Justin II to agree to make annual payments in exchange for a five-year truce on the Mesopotamian front, although the war continued elsewhere. In 576 Khosrau I led his last campaign, an offensive into Anatolia which sacked Sebasteia and Melitene, but ended in disaster: defeated outside Melitene, the Persians suffered heavy losses as they fled across the Euphrates under Byzantine attack. Taking advantage of Persian disarray, the Byzantines raided deep into Khosrau's territory, even mounting amphibious attacks across the Caspian Sea. Khosrau sued for peace, but he decided to continue the war after a victory by his general Tamkhosrau in Armenia in 577, and fighting resumed in Mesopotamia. The Armenian revolt came to an end with a general amnesty, which brought Armenia back into the Sassanid Empire.
Around 570, "Ma 'd-Karib", half-brother of the King of Yemen, requested Khosrau I's intervention. Khosrau I sent a fleet and a small army under a commander called Vahriz to the area near present Aden, and they marched against the capital San'a'l, which was occupied. Saif, son of Mard-Karib, who had accompanied the expedition, became King sometime between 575 and 577. Thus, the Sassanids were able to establish a base in south Arabia to control the sea trade with the east. Later, the south Arabian kingdom renounced Sassanid overlordship, and another Persian expedition was sent in 598 that successfully annexed southern Arabia as a Sassanid province, which lasted until the time of troubles after Khosrau II. Khosrau I's reign witnessed the rise of the dihqans (literally, village lords), the petty landholding nobility who were the backbone of later Sassanid provincial administration and the tax collection system. Khosrau I was a great builder, embellishing his capital, founding new towns, and constructing new buildings. He rebuilt the canals and restocked the farms destroyed in the wars. He built strong fortifications at the passes and placed subject tribes in carefully chosen towns on the frontiers to act as guardians against invaders. He was tolerant of all religions, though he decreed that Zoroastrianism should be the official state religion, and was not unduly disturbed when one of his sons became a Christian. After Khosrau I, Hormizd IV (579590) took the throne. The war with the Byzantines continued to rage intensely but inconclusively until the general Bahram Chobin, dismissed and humiliated by Hormizd, rose in revolt in 589. The following year, Hormizd was overthrown by a palace coup and his son Khosrau II (590628) placed on the throne. However, this change of ruler failed to placate Bahram, who defeated Khosrau, forcing him to flee to Byzantine territory, and seized the throne for himself as Bahram VI. Khosrau asked the Byzantine Emperor Maurice (582602) for assistance against Bahram, offering to cede the western Caucasus to the Byzantines. To cement the alliance, Khosrau also married Maurice's daughter Miriam. Under the command of Khosrau and the Byzantine generals Narses and John Mystacon, the new combined Byzantine-Persian army raised a rebellion against Bahram, defeating him at the Battle of Blarathon in 591. When Khosrau was subsequently restored to power he kept his promise, handing over control of western Armenia and Caucasian Iberia. The new peace arrangement allowed the two empires to focus on military matters elsewhere: Khosrau expanded the Sassanid Empire's eastern frontier while Maurice restored Byzantine control of the Balkans. After Maurice was overthrown and killed by Phocas (602610) in 602, however, Khosrau II used the murder of his benefactor as a pretext to begin a new invasion, which benefited from continuing civil war in the Byzantine Empire and met little effective resistance. Khosrau's generals systematically subdued the heavily fortified frontier cities of Byzantine Mesopotamia and Armenia, laying the foundations for unprecedented expansion. The Persians overran Syria and captured Antioch in 611. In 613, outside Antioch, the Persian generals Shahrbaraz and Shahin decisively defeated a major counter-attack led in person by the Byzantine emperor Heraclius. Thereafter, the Persian advance continued unchecked. Jerusalem fell in 614, Alexandria in 619, and the rest of Egypt by 621. The Sassanid dream of restoring the Achaemenid boundaries was almost complete, while the Byzantine Empire was on the verge of collapse. This remarkable peak of expansion was paralleled by a blossoming of Persian art, music, and architecture.
