THE LAST SASANIANS (628 - 651)
Things fall apart ...
The well-intentioned military reorganisation by Khusrau I - splitting the command between four generals, one spahbad for each of the four quarters of Eranshahr had unintended consequences. By the end of Khusrau II's reign it was clear that the situation was becoming very similar to what it had been in the final years of the Parthian regime. Local dynasts were looking after their own interests, consolidating their own wealth and power, and disregarding the central authority of the Sasanian kings. They were not very concerned about showing solidarity - even when faced by external enemies. Bahram Chobin was the first non-Sasanian (though he was of Parthian descent) to make the bid for supreme power. Others followed.
... the centre cannot hold
Kavad II had killed all his brothers. When he died, there was only his baby son available as a Sasanian heir, who very briefly became king of kings as Ardashir III. Shahrbaraz, Khusrau's sacked general took his chance. He marched on Ctesiphon, killed Ardashir III and made himself king. It was all of a few months before he was murdered in turn.
As there were apparently no male Sasanians left (Kavad II had murdered them all), the next ruler was a daughter of Khusrau II. Queen Buran (Burandukht) saw herself as restoring past glories. Her coins announce:
Buran, restorer of the race of gods
Her restoration was short-lived, deposed and probably murdered by another general, succeeded by another queen (her sister) - they came and went with embarrassing speed, rulers and wannabe rulers, some simultaneously, claiming different parts of the empire: Joshnabandah, Azarmidukht (Burandukht's sister, and general Shahrbaraz's widow), Hurmazd V, Khusrau III, Peroz II, Khusrau IV. All held power fleetingly between 630 and 632.
The last king of kings: Yazdegird III (632 - 651)
Yazdegird III, a previously undiscovered grandson of Khusrau II, was put forward as king by the nobles, led by the spahbad Rustam. He was crowned aged 15 in the temple of Anahita at Estakhr, in Persis, from where the Sasanian dynasty had originated. Did they think the time had come to consolidate Sasanian rule in its traditional homeland? But outside Persis, events were moving fast.
Persia's long-term enemies, the Turks and the Byzantines, were no longer a threat. Exhausted by decades of warfare, with manpower and leadership seriously depleted, a long period of peace was needed for the army to rebuild its strength and confidence. Agriculture had been disrupted by war and natural disasters, and the ruling class was distracted by futile but fatal quarrels within itself.
- by 632: The Arabian peninsula is united under Muhammad; the Sasanians have already been ousted from Yemen and Oman.
- 632, June: Death of Muhammad. Abu Bakr becomes first caliph.
- 633: Arabs invade Iraq and are defeated at the Battle of the Bridges in 634.. They are forced back across the Euphrates by the Savarans, and their leader is trampled to death by an elephant. This was the Sasanians' last military success.
- 634: Crushing Arab victory over Byzantines at Battle of Ajnadayn in Palestine. Death of Abu Bakr. Umar becomes second caliph.
- 636: Arab victory over Byzantines in Syria at Battle of Yarmuk. Sasanian army under Rustam is defeated at Battle of Qadisiyya by Arabs under Caliph Umar. Many troops desert, and convert to Islam.
- 637: March: Ctesiphon is captured; Yazdegird III and his court officials flee to Persis. The legendary "Banner of Kaveh" is captured - a devastating psychological blow. April: Arab victory at the Battle of Jalula, where Sasanians had regrouped. Thousands of Sasanian troops killed. Yazdegird flees to Rayy. Battle of the Iron Bridge: Syrian conquest is complete (October).
- 642: Umar takes Khuzistan after a long struggle. Battle of Nihavand: Umar takes Media.
- 650: Arabs conquer Persis after prolonged struggle. Yazdegird flees to east, like Darius III. He hoped for help from the Turks or from China.
- 651: Yazdegird is murdered in Merv in Chorasmia by a quarrelsome miller who fails to recognise the king of kings.
How did it all happen so quickly? Many factors contributed to the whirlwind Arab success:
In Umar, the second caliph, the Arabs had found a leader of exceptional calibre.
The first caliph, Abu-Bakr, had declared that the Arabs were bringing a message from god, proclaiming equality and justice for all. This was great news for the minorities in the Sasanian empire (and in Byzantium) - the Miaphysite Christians, the 'Nestorian' Christians (Church of the East or Assyrians), Jews, Aramaic speakers, the Arabic peoples of Syria and Palestine, most of whom had no love for their remote and authoritarian governments. There was a popular slogan in Persia, once associated with the Manichaeans:
Ham-e-Baradar, Ham-e-Barabar (All are brothers, all are equals)
The Arabs were welcomed by the elements in Persia that had once supported Mazdak, especially the poor farmers trying to make a life for themselves despite fierce taxation. Many were happy to accept Arab rule and convert to Islam if it meant lower taxes. But it was among the huge number of Iranians enslaved by the Arab conquerors that Islam - and the Arabic language - spread most effectively. With Islam's message of equality, it was eventually impossible for the conquerors to remain an elite - as conquerors elsewhere mostly tried to.
Neither the Persians nor the Byzantines had good enough generals, and their armies were exhausted by decades (in fact centuries) of fighting each other, as well as Turks, Avars, Slavs, Hephthalites ... Even before the Sasanian take-over, the Parthians had been fighting Rome for 200 years. And recently the Sasanians had grossly over-extended themselves during Khusrau II's bid to recover Egypt and Anatolia. Both empires faced the threat of annihilation: the Byzantine empire survived the Arab attacks where the Sasanian didn't. The Arab historian Ibn Khaldun says:
When the Muslims took Ctesiphon, the whole Persian empire was dissolved, and the outlying provinces which remained in Yazdegird's hands were of no avail to him. By contrast, the centre of the Byzantine state was in Constantinople ... the loss of Syria did not harm them.
After the Battle of Qadisiyya in 636, it was every man for himself: once the king of kings had lost his centre of power and authority there was nothing to hold Eranshahr together. And, due to Khusrau I's army reforms, once the Mesopotamian army had been defeated, the whole empire was wide open. The individual provinces, however bravely they resisted, were picked off one at a time.
Yazdegird III was succeeded by his son Peroz II. Peroz (still only a boy) and the remains of the Sasanian court eventually escaped into China, where he was given an imposing title and allowed to build a fire-temple (AD 677). His sister married the Chinese emperor, and the refugees were allowed to join the already-existing Iranian and Zoroastrian communities there. A reconquest was doubtless talked of, and even attempted, but no effective counter-attack ever took place. Peroz's son Narseh wrote about his father (in Chinese):
Peroz requested only a simple burial and the Chinese emperor approved. The entire exiled court was in attendance along with the Chinese emperor. The Chinese emperor held Peroz's shaking hands. Peroz looked west and said: "I have done what I could for my homeland (Persia) and I have no regrets." Then, he looked east and said: "I am grateful to China, my new homeland." Then he looked at his immediate family and all the Persians in attendance and said: "Contribute your talents and devote it to the emperor. We are no longer Persians. We are now Chinese." Then, he died peacefully. A beautiful horse was made to gallop around his coffin 33 times before burial, because this was the number of military victories he had during his lifetime. Peroz was a great Chinese general and great Persian prince devoted and loyal to his people.
The last Sasanian we hear of was Yazdegird III's grandson, Khusrau: according to Chinese sources, he invaded Persia with Turkish allies - but was unsuccessful.
The Arab conquest ended more than a millennium of Iranian domination of Iraq and the plateau. With the Arabs came Islam, which changed Iran for ever. Continue with the story of the Iranian peoples under Islam:
During the Sasanian period, as all memory of the Achaemenids and Parthians vanished, Iranian poets began to constuct their own history - based on ancient Zoroastrian traditions. Darius and Alexander appear - transformed. The Sasanian kings do figure in something more like a historical narrative. As Iran succumbed to Arab rule and to Islam, these stories became more and more important to the survival of an Iranian identity - and form the core of the Shahnameh (The Book of Kings) begun by Firdowsi in the 10th century AD at the splendid court of the Iranian Samanids and completed under the equally splendid Ghaznavids, a dynasty of Afghan origin.
