Dynasty of Ancient Persia (224-651 CE), which at its largest covered an area of modern Iran and Iraq, Azerbaijan, Armenia, Georgia and large parts of Pakistan. Because of its large area, the title of the king was "King of kings of Iran and non-Iran". The dynasty is named after Sasan, an ancestor of Shah Ardashir 1.

The governmental structure of the Sassanian Persia was centralized, where local rulers were removed early in the dynasty's history. Instead, members of the Sassanian family were made provincial governors. Until the 4th century the appointed heir to the throne would generally rule one of the provinces as "Great King"; Kushanshahr (formerly Kushan Empire) and Armenia were common.
The hierarchic structure below the top levels was strictly defined. The local kings and governors, as well as officials in the cities and provinces reported directly to the royal court.
The centralized structure of the Sassanian dynasty created a very effective army, important both for conquests and defence.
Despite the initial attempts to secure peaceful and effective transfer of power, the empire would see several disputes over power, and at times parallel rulers.
Great imperial ambitions of the rulers, influenced by the memory of the Achaemenid Persian empire, brought Persia into numerous conflicts with the Roman (later Byzantine) Empire.
As with most other country in this period, agriculture and husbandry were the central economic activities, and involving the largest work force. Thanks to both a diverse agriculture and rich yields, there was ample room for craftsmanship as well as a powerful administration in the Sassanid Empire.
As the empire covered enormous areas, and most of the time could guarantee security inside these borders, trade could develop and allowed the specialization of crafts.
International trade was limited, due to the long periods of tensions between the empire and its neighbours.
The state religion of the Sassanians was Zoroastrianism, and the religion was closely linked to the state. During the Sassanian period Zoroastrianism went through a development leading it into a shape much resembling its modern form.
Among the changes that can be traced to this period, is the increased importance of the fire cult and the worship of Ahura Mazda, where all gods were made definitely subordinate of him.
The practice of animal sacrifice appears to have disappeared in this period. the last known occurrence of it dates to around 400. Today this is an illegal practice.
Zoroastrian priests, mobed, acted as more than only religious officials. Due to their knowledge of reading and writing, they were also important in local administration. To some extent they played an important role in the selection of new rulers and the policy of the cental government.
Thanks to the strong position of Zoroastrianism, believers of other faiths at times suffered from persecution. With the rise of Christianity around 300, Christians were especially victims of this. A new wave of oppression came in the 5th century.
There was likewise much control with deviations inside Zoroastrianism, and defection from Zoroastrianism was made a capital crime. In the 6th century, the ideas around the new Zoroastrian concept of Zurvan were declared heretical, and followers of the teachings of Mazdak were killed in a great massacre.
After the fall of the dynasty, and the arrival of Muslim rulers over the old Iranian territories, Zoroastrianism would gradually loose its importance.
Art and Literature
The language of the Sassanians was Pahlavi. The Sassanian rulers had built many great monuments, of which the ones at Ctesiphon, Firuzabad and Sarvestan are especially noted. With the building of the royal palace at Ctesiphon around 600 was the world's largest single-span vault built. This still stands today (see photo).
The most distinct form of art of the Sassanian period are the rock sculptures carved on limestone cliffs, of which most are found in the Fars region.
Other arts that saw great advances under the Sassanians were metalwork and gem engraving.
Literature was of some importance field, and the Sassanian period was one where the oral tradition was gradually replaced by a written tradition. Most of it dealt with religious and historical matters, and is of relatively little literal interest. Towards the end of the Sassanian period were many great works were translated into Pahlavi.
