The Sasanian or Sassanid Empire (224-651 CE) was the last imperial government before the Arab invasion of Iran. This Sasanian dynasty, which ruled Iran from 224 to 651 AD, belonged to the Sassanid family. The founder of this dynasty was Ardeshir Babakan known as Ardashir I, who was able to establish this government by defeating Artabanus IV of Prthia. The Sassanid government had succeeded in uniting the country once again after the Achaemenids and creating a powerful empire. The Sassanid government, which ruled over a large part of West Asia, was the superpower of the world for almost 400 years, along with the Byzantine Empire.

The Sasanian Empire was the last in a series of Persian empires which had for centuries been seen as the rivals of Greco-Roman civilization. It was also the last before the coming of Islam changed the entire character of Persian or Iranian civilization.

In many ways, the Sasanian Empire already had one foot in this new medieval world, yet its self-image was firmly cast in the mould of ancient Iran and the Empire regarded itself as the true heir of that great Achaemenid Persian Empire destroyed by Alexander the Great hundreds of years earlier.

In some ways Sassanian Iran also had more in common with Hindu India than subsequent Muslim Iran. People were divided into “castes” with an Iranian warrior elite of supposed “Aryan” origin dominating others of inferior birth. The domain of the Shahanshah or Sassanian King of Kings become identified with Iranshahr, the Land of the Iranians and of the Zoroastrian religion. There were many Iranians outside the Sassanian Empire and many non-Iranians within, yet this ethnically based attitude was deep rooted and would, to some extent, even survive the egalitarian spirit of Islam. Like their Roman rivals the Sassanian Iranians were trapped within an archaic view of the world. While the Romans believed that they were the natural masters of civilization, the Iranians believed that their King was the divinely ordained master of all kings.



The Character of the Sasanian Empire

Though the Sasanians modeled themselves on the ancient Achaemenid Persian Empire, their state was really very different. Like Romans the Sasanian Empire relied heavily on slave labor, but at the same time Sassanian merchants ranged far and wide, gradually ousting the Romans from the lucrative Indian Ocean trade routes. It was also a time of increased metallurgical production so that Iran earned a somewhat undeserved reputation as the “ََArmory of Asia”. In fact, the main Sassanian mining centers were on the fringes of the Empire, in Armenia, the Caucuses and above all Transoxiana. The extraordinary mineral wealth of the Pamir mountains on the eastern horizon of the Sassanian Empire led to a legend among the Iranian-speaking Tajiks which is still told today. It was said that when God was making the world he tripped over the Pamirs, dropping his jar of minerals which spread across the region.

Sassanid Emperor 

At the heart of the Sasanian Empire sat the Emperor (Shahanshah) – a figure of huge power and prestige. The previous Parthian dynasty, which drove Alexander the Great‘s successors out of Iran, had adopted a Hellenistic Greeks deification of kingship. This, when added to ancient Iranian cults, placed the ruler between heaven and earth as a link between his subjects and the great god Ahura Mazda. Around the ruler stood his family, held together by clan loyalty and ancestor veneration. No Sassanian books on government have survived but the 9th century “Book of the Crown” is based on a Sassanian prototype. It emphasizes the splendor of a Divinely ordained ruler, the passivity of his subjects, and makes very few concessions to concepts of justice, generosity and compassion. Such abstract ideas had to await a later series of Muslim Persian and Arabic “Mirrors for Princes”.

Class Division in Sasanian Society  

The division of social classes in the Sassanid period is based on the same as stated in the Avesta, the four Sassanid classes were:

A- Clerics (asronãn)
B- Warriors (arteshtarãn)
C- Administrative staff (dabirãn)
D- Common people (villagers or Wastrioshãn)

In a realistic point of view, we will find that the society of that time was divided into two general classes. The upper class, which included the royal family, the old families of local rulers and military officials; they were called by the name of Bozorgan meaning Lords or Grandee.

And the lower class; which was the mass of people and included: farmers, artisans and craftsmen. But what is obvious in the Sasanian social structure is that the people at the bottom of this pyramid were not able to raise their class and they and their descendants would remain in the same class forever. It is a gross class discrimination that questions the nature of their humanitarianism to the extent that promotion from the lower class to the upper class was impossible.



Sasanian Empire Religion 

The declaration of Zoroastrianism as the official religion created a type of unity in the religions in Iran. During the Sassanid period, Zoroastrian religion was declared an official religion by the government, and later Zoroastrianism was divided into different sects.
During the Sassanid era, religion gave legitimacy to the kings and the government. The people would be completely obedient to the king, although this kind of attitude had led to religious tyranny to some extent so that the people would avoid this closed atmosphere and sometimes turn to other religions or superstitions. Before the Sassanids, there was no official religion in Iran and the tribes of Iran each had their own religion.
During this period, the people of Iran had a strong religious orientation. It was on this basis that the Sassanid governments considered themselves dependent on religion, and played a role in keeping religious ceremonies alive. As the Zoroastrian fire temples (Atashkdeh) were still lit years after Islam, and their effect is still present everywhere in Iran now, the religion was alive in all the places under the influence of the Sassanids.

Sasanian script, Literature and Education 

The most famous scripts used during the Sassanid era are Ashkani Pahlavi script and Sassanid Pahlavi scripts. These scripts were adapted from the Aramaic script, and all administrative correspondence, historical literary writings and books of Sassanid period were written in this script.

In those days, education was only reserved for Bozorgan (Grandees) and the common people were deprived of education and the benefit of science and knowledge.

Jondishapur Academy also known as Jondi Shapur university was one of the important centers of science, education and research, and many scientists and polymaths were engaged in research there. King Anushiravan Sassanid sent some people to India to acquire knowledge. He also warmly accepted and supported some Greek philosophers who had fled to Iran due to the narrow-mindedness and bigotry of the Roman Christians.



Roman – Persian Wars 

The Roman wars are a series of wars that started in 54 BC with the invasion of Roman commander Marcus Licinius Crassus who played a key role in the transformation of the Roman Republic into the Roman Empire. Crassus invaded Iran during the reign of Parthian king Orod II and continued until the end of the Sassanid era. These wars ended with the rise of Islam and the Arab invasion, by which time both empires were weakened by the long lasting conflicts. Although these wars lasted for 700 years, the borders remained largely unchanged. These battles were a kind of tiring tug-of-war between the two empires: the cities, fortresses and provinces of both sides were continuously conquered, looted, handed over and destroyed.

None of the two empires had the power and strength to mount a long-term campaign in the enemy’s land and far from their borders. Both sides camped outside their borders in the enemy’s land, but sooner or later the balance between them was always maintained.



Victory of Shapur I over Romans

Shapur I Sassanid was the second emperor of the Sasanian Empire. He was chosen as the regent during the lifetime of his father Ardeshir I. During his father’s reign, he participated in many battles as the viceroy of Iran and found a high position with Ardeshir I. Shapur I of Sassanid was crowned in 240 AD.

In 238, while his father was still alive, Shapur defeated the Romans who invaded Iran and conquered a strong fortress between Iran and Rome. The army of Gordianus III – the young emperor of Rome – was so beaten that the emperor himself was killed. A little later, the king Ardeshir also died and Shapur became the “Emperor of Iran” and continued the war with Romans. Philip the Arab, the Roman emperor came to frustration, and apologized to Shapur and paid a compensation of five hundred thousand dinars for the peace proposal.

In the third war, he defeated Romans with great difficulty. One of the consequences of the war between Iran and Rome was the conquest of Armenia. The acquisition of Armenia inflicted a great defeat on Rome. Sassanid Shapur I succeeded in defeating Valerian in 254 AD.

Sasanian Historical Monuments

Many historical monuments have been left from the Sassanid era, including palaces, hunting lodges, fire temples, religious monuments, inscriptions, reliefs and a statue in a cave.



Ctesiphon – Sasanian Empire Capital

Taq Kasra or Khosrow’s Arch also referred to as Arch of Ctesiphon is one of the most beautiful historical attractions in the Middle East. Located in Iraq, this site is considered one of the most famous tourist attractions of the country.

Present Iraq was a part of ancient Iran under Sasanians and was much later separated from Iran. Taq Kasra is currently located in Diyala province, at a distance of 40 kilometers from the southeast banks of the Tigris river. In the past, this building was located at the entrance of a city called Ctesiphon. The neglect of the Iraqi people to this Iranian building and their lack of care has caused wear and damage to this ancient Sassanid site.

History of Ctesiphon Arch
Of course, some archaeologists believe that this building dates back to the Parthian period. They believe that only its restoration and reconstruction takes place in the Sassanid era. Taq Kasra or Iwan-e Madain, which is also known as Khosrow Arch, is attributed to the reign of king Anushiravan. The building is very similar to other Sassanid buildings left from the third century. It dates back to almost 1700 years ago and was a part of a large royal palace whose size was 365 to 275 meters. Currently, the ruins that remained were part of the Kasri arch mansion, which included the royal hall and the treasury building.





The ancient city of Bishapur is one of the most valuable historical cities left from the Sasanian Empire. The site is located near the city of Kazerun, Fars province of Iran. According to an inscription, the city was founded in 266 AD by Shapur I (241-272). Iranians and Roman captives cooperated in building the city in this area of a good climate. Roman engineering and art has influenced the architecture of Bishapur, and it is easy to see the similarities in the style of the two nations.

The eastern mosaic porch, Anahita Temple, Palace known as Valerian’s palace, Hall of Audience, a Bath and a Caravanserai are among the most important historical monuments. The historical remains in nearby Tang-e Chogan and many monuments in this ancient city undoubtedly attract the attention of countless visitors.




Ardashir’s Palace- Firuz Abad

Firuzabad was the first capital of the Sasanian Empire that still exists and offers amazing attractions. The ancient buildings of the Sasanian era are located in this town located 110 km south of Shiraz. Ardeshir’s Palace in Firuzabad is one of the most important and valuable historical sites in this ancient city.
The scales of Ardeshir’s Palace is about 104 x 55 m and consists of three parts. It has a courtyard with two attached porches and halls, a high Iwan and three domed halls inside. These are the three main parts of the Palace. In the architecture of Ardeshir Babakan Palace, the important and glorious materials of the era, which were plaster and tiles, have been used and had doubled the beauty of the palace.

This monument is the first Sassanid building that has a porch and a dome. The masters of architecture and artists of the Sassanid era used semi-cut stones in the construction of different parts of the building and showed off their style and techniques. Beautiful and eye-catching stucco decorations are other pure Iranian skills that are displayed in this building.




Qal’eh Dokhtar – Firuzabad

Qal’eh Dokhtar, also known as Dezh Dokhtar meaning “The Maiden Castle” is a castle built by Ardashir I, the founder of the Sasanian Empire in 209 AD.
Located 6 km from Firouzabad, on a slope in the heart of the mountains, Ghal’eh Dokhtar was a stronghold and served as an important obstacle for the enemies to cross the “Tangab Gorge”. General architectural features of the palace inside this castle, in comparison with Ardashir palace in Firouzabad plain, show that the Maiden Castle was founded during Ardeshir I‘s wars with Parthians before his final victory over the last Parthian king, Ardavan IV (Arthabanus IV) in 224 AD.

The main fortifications of Qal’eh Dokhtar include an outer wall that extends over a sloping cliff with an overall shape of a trapezoid. These fortifications started from the lower part of the “Tangab Gorge” and extended to the highest part of the mountain where the inner castle is located. The geometrical multi-level layout of the inner palace is in complete contrast to the non-geometrical mode of the castle itself, which is based on the natural shape of the mountain.

Naqsh-e Rostam – Mardasht

The Sasaninan Monarchs who considered themselves to be worthy successors to the Achaemenids, revived the art of rock carvings to immortalize the most important events in their history.
Near 8 centuries later than Naqsh-e Rostam was founded, Sassanian monarchs Ardeshir I and his son Shapur I, commissioned rock panels consecrated to their glory; they revived the Achaemenid principle and had their works executed in prestigious localities. Thus, on the cliffs of this necropolis, at the foot of the grand Achaemenid tombs of Darius, Xerxes, Artazerxes I, and Darius II, Sassanians created Bas-reliefs showing their investiture or triumphal scenes.

Taq-e Bostan 

The Persian term Taq-e Bustan, meaning ‘arch of the garden’ is the name of one of those enchanting places so loved by the Iranians in which nature and Man worked together to create a master peace. Laid out around a pool surrounded by large trees that provide refreshing shade, this site a few miles from Kermanshah is dominated by precipitous rock faces, at the base of which ancient sculptors expressed their artistry. Taq-i Bustan is the place where the Sassanian sovereigns, in obedience to an ancient water cult dedicated to the goddess Anahita, built a series of extremely interesting rock-cut monuments.
Here, however, instead of investiture or triumphal scenes carved on the rock, there are artificial grottoes entirely hewn out of the rock.

Sassanid Archaeological Landscape of Fars Region

UNESCO World heritage 

Eight archaeological sites located in three different areas of Fars Province in south Iran including Firuzabad, Bishapur and Sarvestan have been recently registered as world heritage sites. These fortresses, palaces and city plans date back to the Sasanian Era , which stretched across the region from 224 to 651 CE. Among these sites is Qaleh Dokhtar at Firuz Abad, the capital built by Ardashir Babakan, as well as Bishapur, a city and architectural structures of his successor, Shapur I. The archaeological landscape reflects the optimized utilization of natural topography and bears witness to the influence of Achaemenid and Parthian cultural traditions and of Roman art, which had a significant impact on the architecture of the Islamic era.

The Fall of the Sasanian Empire 

The Sassanid era is one of the most important and influential parts of Iran’s history. During this period, the fourth great Iranian dynasty arose, which was equal to its predecessors in terms of glory and power. This dynasty colain 651 AD during the time of Yazdgerd III due to the Arab invasion. Although this empire was defeated in the war, there are many reasons behind this failure. In the following, we will examine these causes.


Causes of the fall of the Sassanids

Although Yazdgerd III is the last king of the Sassanid dynasty, the reasons for the defeat of the Iranians against the Arabs go back to the time of Khosrow II also known as Khosrow Parviz. As one of the most powerful Sassanid kings, Khosrow had actions that caused the foundation of this historical failure.



Although the collapse of the Sasanian Empire was sudden and unexpected, the Sassanian heritage remained important in Iran, if not always beneficial. The early 7th century saw defeat in a war of epic proportions against the Romano-Byzantines. From a Mediterranean perspective this conflict marked the true “end of antiquity”. For Iran it paved the way for the Muslim Arabs to make the first successful invasion from the west since the days of Alexander the Great.

Paradoxically, perhaps, this crushing of the Sasanians led to what has been described as “The Golden Age of Persia”. It would also see eastern and western Iran truly united for the first time in history. Some aspects of Sassanian civilization would survive in Scmirechye, south of Lake Balkash, as late as the 12th century. Meanwhile the brilliant civilization of Classical Islam, the world of the Caliphs as still recalled in the legendary “Thousand and One Nights”, owed a great deal to its Sassanian predecessor. This was particularly true in military matters. The first Arabic book on tactics and army organization is believed to have been a translation, now lost, of a Persian work written for Ardashir back in the 3rd century AD.
