Sassanid Empire

The Sassanid Empire, or Sassanian Dynasty, [] was the Persian dynasty that lasted from 224 to 651 AD.Wiesehofer, Joseph 1996. Ancient Persia. New York: I.B. Taurus

The Sassanid Empire, which succeeded the Parthian Empire, was recognized as one of the two great powers in Western Asia, alongside the Roman Empire and later the Byzantine Empire, for more than 400 years.

 History 
The Sassanid dynasty was founded by Ardashir I when he defeated the last Parthian (Arsacid) king, Artabanus IV, and it ended when the last Sassanid Shahanshah (King of Kings), Yazdegerd III (632–651), lost a fourteen-year struggle to drive out the early Arab Caliphate, the first of the Islamic empires.

The Sassanid Empire's traditional territory included what are now Iran, Iraq, Armenia, Afghanistan, Egypt and eastern Turkey and parts of Syria, Pakistan, Caucasus, Central Asia and Arabia.

 Influence 
The Sassanid era is considered to be one of the most important and influential historical periods in Iran. In many ways; the Sassanid Empire saw the highest achievement of Persian civilization and was the last great Persian empire before the Muslim conquest and the adoption of Islam.

Sassanid Persia influenced the Roman Empire considerably,Bury J.B. 1923. History of the later Roman Empire. Macmillan, London.p109 and the Romans reserved for the Sassanid Persians the status of equals. The Roman Emperor wrote letters to the Persian Shahanshah, which were addressed to "my brother". The Sassanids' cultural influence extended far beyond the empire's territorial borders by reaching as far as Western Europe,Durant, Will The story of civilization, 4: The Age of faith.

This influence carried forward to the early Islamic world. The Sassanids' unique aristocratic culture transformed the Islamic conquest of Iran into a Persian renaissance. Much of what later became known as Islamic culture, architecture, writing and other skills were borrowed from the Sassanids and spread throughout the broader Muslim world.

 Religion 
The Sassanians began making the empire more Iranian after the fall of the Parthians by implementing and promoting Zoroastrianism in it. 

Zoroastrianism was the backbone and state religion of the Sassanid Empire. It was one of the first monotheistic religions; the Sassanians believed in one god. Many of those who did not follow the faith were persecuted by the government.

 Decline 
In the spring of 632, a grandson of Khosrau I, Yazdegerd III, who had lived in hiding, ascended the throne. The same year, the first raiders from the Arab tribes made their raids into Persian territory and were united by Islam. Years of warfare had exhausted both the Byzantines and the Persians. Also, the Persianss were further weakened by economic decline, heavy taxation, religious unrest, rigid social classes, the increasing power of the provincial landholders and a rapid turnover of rulers. 

Those factors made the Islamic conquest of Persia easier than if it had been attempted earlier.

The Sassanids never mounted a truly effective resistance to the pressure that was applied by the Muslim conquests.
