== Etymology ==
== Etymology ==
The name of Yazdegerd is a combination of the [[Old Iranian]] ''yazad yazata''- "divine being" and ''-karta'' "made", and thus stands for "God-made", comparable to Iranian ''Bagkart'' and [[Greek language|Greek]] ''Theoktistos''.{{sfn|Shahbazi|2003}} The name of Yazdegerd is known in other languages as follows: [[Middle Persian|Pahlavi]] ''Yazdekert''; [[New Persian]] ''Yazd(e)gerd''; [[Syriac language|Syriac]] ''Yazdegerd'', ''Izdegerd'', and ''Yazdeger''; [[Armenian language|Armenian]] ''Yazkert''; [[Talmudic]] ''Izdeger'' and ''Azger''; [[Arabic]] ''Yazdeijerd''; Greek ''Isdigerdes''.{{sfn|Shahbazi|2003}}

Yazdegerd was the son of prince [[Shahriyar (son of Khosrow II)|Shahriyar]] and the grandson of the last prominent shah of Iran, [[Khosrow II]] ({{reign|590|628}}), who was in 628 overthrown and executed by his own son [[Kavad II]], who proceeded to have all his brothers and half-brothers executed, including Shahriyar.{{sfn|Kia|2016|p=284}} This dealt a heavy blow to the empire, which it would never recover from. Furthermore, the fall of Khosrow II also culminated in a [[Sasanian civil war of 628–632|civil war lasting four years]], with the most powerful members of the nobility gaining full autonomy and starting to create their own government. The hostilities between the [[Persians|Persian]] (''Parsig'') and [[Parthia]]n (''Pahlav'') noble-families were also resumed, which split up the wealth of the nation.{{sfn|Shahbazi|2005}} A few months later, a [[Plague of Sheroe|devastating plague]] swept through the western Sasanian provinces, killing half of its population including Kavad II.{{sfn|Shahbazi|2005}}
Yazdegerd was the son of prince [[Shahriyar (son of Khosrow II)|Shahriyar]] and the grandson of [[Khosrow II]] ({{reign|590|628}}), the last prominent shah of Iran. Khosrow II had been overthrown and executed in 628 by his own son Sheroe, who took the name [[Kavad II]] upon gaining the throne. Kavad then ordered the execution of all his brothers and half-brothers, including Yazdegerd's father Shahriyar.{{sfn|Kia|2016|p=284}} The purging of the ranks of the ruling family dealt a blow to the empire from which it would never recover.


He was succeeded by his eight-year-old son [[Ardashir III]], [[Siege of Ctesiphon (629)|who was killed two years later]] by the distinguished Sasanian general [[Shahrbaraz]], who was in turn murdered forty days later in a coup by the ''[[Seven Great Houses of Iran|Pahlav]]'' leader [[Farrukh Hormizd]], who installed the daughter of Khosrow II, [[Boran]], on the throne.{{sfn|Pourshariati|2008}}{{pn|date=October 2024}} She was deposed a year later, and a succession of rulers followed one another, until Boran was sovereign once more in 631, only to be killed the following year, seemingly by the ''Parsig'' leader [[Piruz Khosrow]].{{sfn|Pourshariati|2008|p=218}} The most powerful magnates in the empire, [[Rostam Farrokhzad]]{{efn|Rostam Farrokhzad was a son of Farrukh Hormizd, and had succeeded him as the leader of the ''Pahlav'' in 631, when the latter was killed after attempting to usurp the Sasanian throne.}} and Piruz Khosrow, now threatened by their own men, eventually agreed to work together, and installed Yazdegerd III on the throne, thus putting an end to the civil war.{{sfn|Pourshariati|2008|p=219}} He was crowned in the [[Anahid fire-temple]] in [[Istakhr]], where he had been hiding during the civil war. The temple was the very place where the first Sasanian shah [[Ardashir I]] ({{reign|224|242}}) had crowned himself, indicating that the reason behind Yazdegerd's coronation at the same place was due to hopes for a rejuvenation of the empire.{{sfn|Daryaee|2010|p=51}} He was almost the last living member of the [[House of Sasan]].{{sfn|Frye|1983|p=171}} Most scholars agree that Yazdegerd was eight years old at his coronation.{{sfn|Shahbazi|2005}}{{sfn|Kia|2016|p=284}}{{sfn|Pourshariati|2008|p=257}}
The murder of Khosrow II ignited a [[Sasanian civil war of 628–632|civil war that lasted four years]], as the most powerful members of the nobility created their own autonomous government. Hostilities between the [[Persians|Persian]] (''Parsig'') and [[Parthia]]n (''[[Seven Great Houses of Iran|Pahlav]]'') noble families also resumed; they divided the treasury between themselves.{{sfn|Shahbazi|2005}} And months later, a [[Plague of Sheroe|devastating plague]] swept through the western Sasanian provinces and killed half of the population. Kavad II was one of its victims.{{sfn|Shahbazi|2005}}


== Reign ==
Kavad was succeeded by his eight-year-old son [[Ardashir III]] [[Siege of Ctesiphon (629)|who was killed two years later]] by the distinguished Sasanian general [[Shahrbaraz]]. Forty days later Shahrbaraz was deposed and murdered by the Pahlav leader [[Farrukh Hormizd]], who installed the daughter of Khosrow II, [[Boran]], on the throne.{{sfn|Pourshariati|2008}}{{pn|date=October 2024}} She was deposed a year later, and a succession of rulers followed until Boran was sovereign once more in 631, only to be murdered the following year by the ''Parsig'' leader [[Piruz Khosrow]].{{sfn|Pourshariati|2008|p=218}}
===Conditions of the empire===
 
Eventually the two most powerful magnates in the empire, [[Rostam Farrokhzad]]{{efn|Rostam Farrokhzad was a son of Farrukh Hormizd, and had succeeded him as the leader of the ''Pahlav'' in 631, when the latter was killed after attempting to usurp the Sasanian throne.}} and Piruz Khosrow—threatened by their own men—agreed to ally. They installed Yazdegerd III on the throne, putting an end to the civil war.{{sfn|Pourshariati|2008|p=219}} He was crowned in the [[Temple of Anahita, Istakhr]], where he had been hiding during the civil war. The site was chosen to be a symbol of the empire's rejuvenation, as it was the very place where the first Sasanian shah [[Ardashir I]] ({{reign|224|242}}) had crowned himself four centuries earlier. {{sfn|Daryaee|2010|p=51}} Due to Kavad's massacre of his family, the new shah was among the few surviving members of the [[House of Sasan]].{{sfn|Frye|1983|p=171}} Most scholars agree that Yazdegerd was eight years old at his coronation.{{sfn|Shahbazi|2005}}{{sfn|Kia|2016|p=284}}{{sfn|Pourshariati|2008|p=257}} His coronation occurred around the same time that [[Abu Bakr]] became Caliph.<ref>{{Cite book |title=History of Civilizations of Central Asia |publisher=UNESCO |year=2006 |isbn=978-9231032110 |pages=445}}</ref>

Yazdegerd, however, did not have the authority required to bring stability to his extensive empire, which was swiftly falling apart due to ceaseless internal conflicts between the army commanders, courtiers, and powerful members of the aristocracy, who were fighting amongst themselves and wiping each other out. Many of the governors of the empire had proclaimed independence and carved out their own kingdom.{{sfn|Kia|2016|p=284}} The governors of the provinces of [[Mazun (Sasanian province)|Mazun]] and [[Sasanian Yemen|Yemen]] had already asserted their independence during the civil war of 628–632, thus resulting in the disintegration of Sasanian rule in the [[Arabian Peninsula]], [[Early Muslim conquests|which was uniting under the banner of Islam]].{{sfn|Morony|1986|pp=203–210}} The [[Iranologist]] [[Khodadad Rezakhani]] argues that the Sasanians had most likely lost much of their possessions after Khosrow II's execution in 628.{{sfn|Rezakhani|2019|p=242}}
The eight-year-old Yazdegerd lacked the authority needed to bring stability to an empire that was quickly falling apart due to ceaseless internal conflict. Army commanders, courtiers, and powerful members of the aristocracy fought amongst each other in feuds that were often deadly. Many regional governors had proclaimed their independence from the crown and carved out their own kingdoms.{{sfn|Kia|2016|p=284}} The governors of the provinces of [[Mazun (Sasanian province)|Mazun]] and [[Sasanian Yemen|Yemen]] had already asserted their independence during the civil war of 628–632, resulting in the disintegration of Sasanian rule over the [[Arabs|Arab]] tribes of the [[Arabian Peninsula]] [[Early Muslim conquests|who had united under the banner of Islam]].{{sfn|Morony|1986|pp=203–210}} The [[Iranologist]] [[Khodadad Rezakhani]] argues that the Sasanians had likely already lost many of their possessions after Khosrow II's overthrow in 628.{{sfn|Rezakhani|2019|p=242}}


The empire was starting to look more like the Parthian feudal system before the fall of the [[Parthian Empire|Arsacid Empire]].{{sfn|Daryaee|2014|p=36}} Yazdegerd, although being acknowledged as the rightful monarch by both the ''Parsig'' and ''Pahlav'' factions, does not seem to have held sway over all of his empire. Indeed, during the first years of his rule coins were only minted in [[Pars (Sasanian province)|Pars]], [[Sakastan (Sasanian province)|Sakastan]], and [[Khuzistan (Sasanian province)|Khuzestan]], approximately corresponding to the regions of the southwest (''Xwarwarān'') and southeast (''Nēmrōz''), where the ''Parsig'' was based.{{sfn|Pourshariati|2008|pp=221–222}} The ''Pahlav'', who were mainly based in the northern portion of the empire, refused to mint coins of him.{{sfn|Pourshariati|2008|pp=221–222}} Even in the south Yazdegerd's rule was not seemingly secure; a Sasanian claimant to the throne, [[Khosrow IV]], minted coins at [[Susa]] in [[Khuzistan (Sasanian province)|Khuzestan]] around this time, which he would do till 636.{{sfn|Daryaee|2010|pp=48–49}} According to Rezakhani, Yazdegerd seemingly did not control [[Mesopotamia]], including the capital of [[Ctesiphon]]. He argues that the conspiring aristocrats and the population of Ctesiphon, "do not appear to have been too successful or eager in bringing Yazdgerd to the capital."{{sfn|Rezakhani|2019|p=242}}
By 632, the Sasanian state resembled the [[Feudalism|feudal]] system of the [[Parthian Empire]] at its collapse in 224.{{sfn|Daryaee|2014|p=36}} Yazdegerd, though acknowledged by both the ''Parsig'' and ''Pahlav'' factions as the rightful monarch, was not in control of the empire. Indeed, during the first years of his rule the ''Pahlav'', based in the north, refused to mint coins of him.{{sfn|Pourshariati|2008|pp=221–222}}  


The empire was also at the same time invaded on all fronts; by the [[Göktürks]] in the east, and by [[Khazars]] in the west, who raided [[Sasanian Armenia|Armenia]] and [[Adurbadagan]].{{sfn|Kia|2016|pp=284–285}} The Sasanian army had been heavily weakened due to the [[Byzantine–Sasanian War of 602–628|war with the Byzantines]] and internal conflict.{{sfn|Daryaee|2014|p=37}} The circumstances were so chaotic, and the condition of the nation so alarming, that "the Persians openly spoke of the imminent downfall of their empire, and saw its portents in natural calamities."{{sfn|Shahbazi|2005}}

===Early clash with the Muslim Arabs===
The empire was being invaded on two fronts; by the [[Göktürks]] in the east and by [[Khazars]] in the west. The Khazars raided [[Sasanian Armenia|Armenia]] and [[Adurbadagan]].{{sfn|Kia|2016|pp=284–285}} The Sasanian army had been heavily weakened due to the [[Byzantine–Sasanian War of 602–628|war with the Byzantines]] and to its continuous internal conflict.{{sfn|Daryaee|2014|p=37}} The circumstances were so chaotic, and the condition of the state so alarming, that "the Persians openly spoke of the imminent downfall of their empire, and saw its portents in natural calamities."{{sfn|Shahbazi|2005}}

In May 633, the Muslims defeated a Sasanian force under [[Azadbeh]] near the important strategic Sasanian city of [[Al-Hira|Hira]], which was shortly afterwards occupied. After the fall of Hira, Yazdegerd began to pay greater attention to the Muslims; [[Rostam Farrokhzad]] sent an army under the Persian military officer [[Bahman Jadhuyih]] and the [[Armenians|Armenian]] military officer [[Jalinus]] against the Muslims. Rostam is known to have told Bahman secretly that: "if Jalinus returns to the like of his defeat, then cut off his head."{{sfn|Pourshariati|2008|p=217}} The Sasanian army managed to defeat the Muslims at the [[Battle of the Bridge]].
In 633 Muslim Arabs defeated a Sasanian force under [[Azadbeh]] near the strategically important Sasanian city [[Al-Hira|Hira]], which the victors then occupied in short order. Yazdegerd's ministers began paying heed to the Muslims after the loss of Hira. [[Rostam Farrokhzad]] sent an army commanded by [[Bahman Jadhuyih]] and the [[Armenians|Armenian]] [[Jalinus]] to face the enemy. Rostam ordered Bahman to return with Jalinus's head if the Armenian general lost. {{sfn|Pourshariati|2008|p=217}} The Sasanian army managed to defeat the Muslims at the [[Battle of the Bridge]].


In 636, Yazdegerd III ordered [[Rostam Farrokhzad]] to subdue the invading Arabs and then told him: "Today you are the [most prominent] man among the Iranians. You see that the people of Iran have not faced a situation like this since the family of [[Ardashir I]] assumed power."{{sfn|Pourshariati|2008|p=217}} Envoys then came to Yazdegerd III asking him to consider the dismissal of Rostam in order to replace him with someone around whom the people would rally.{{sfn|al-Tabari|1992|p=44}}

Yazdegerd III asked Rostam for an assessment of the Arab forces since they had camped at Qadisiyyah.{{sfn|Pourshariati|2008|p=224}} [[Rostam Farrokhzad]] stated that the Arabs were "a pack of wolves, falling upon unsuspecting shepherds and annihilating them."{{sfn|Pourshariati|2008|p=224}} Yazdegerd III responds to Rostam by saying

However, the Sasanian army suffered a crushing defeat at the [[Battle of al-Qadisiyyah]], with [[Rostam Farrokhzad|Rostam]], [[Bahman Jaduya|Bahman]], Jalinus and two Armenian princes named Grigor II Novirak and [[Mushegh III Mamikonian]] being killed during the battle. The Arabs then marched towards the Sasanian capital of [[Ctesiphon]] without meeting any resistance. Yazdegerd took his treasury, and along with 1,000 of his servants fled to [[Hulwan]] in [[Media (region)|Media]], leaving Rostam Farrokhzad's brother [[Farrukhzad]] in charge of Ctesiphon. Farrukhzad, however, did not attempt any resistance and also went to Hulwan. The Arabs subsequently reached Ctesiphon, [[Siege of Ctesiphon (637)|besieged]] the western parts of the city, and soon occupied all of it.{{sfn|Zarrinkub|1975|p=12}}<ref name="Bearman 2013">{{cite journal|last=Bearman|first=P. |author2=Th.

However, in reality, it was far from it. The battle served as a wake-up call for the Iranian armies, who became conscious that persistent factionalism could result in their inevitable destruction.{{sfn|Pourshariati|2008|p=234}} [[Al-Tabari]] emphasizes this, stating that after the fall of Ctesiphon "the people... were about to go their separate ways, they started to incite one another: 'If you disperse now, you will never get together again; this is a spot that sends us in different directions'."{{sfn|Pourshariati|2008|pp=234–235}}
The two armies clashed again 636. The [[Battle of al-Qadisiyyah]] resulted in a crushing defeat for the Sasanian army. Rostam, Bahman Jaduya, Jalinus, and the Armenian princes Grigor II Novirak and [[Mushegh III Mamikonian]] were all slain in the fighting. The Arabs then headed for the imperial capital Ctesiphon, meeting no resistance along the way. Yazdegerd fled with the treasury and 1,000 servants to [[Hulwan]] in [[Media (region)|Media]], leaving Rostam's brother [[Farrukhzad]] in charge of the capital. But rather than stay and fight the Arabs, Farrukhzad also fled to Hulwan.

The Iranian defeat at al-Qadisiyyah has often been described as a turning point in the Arab invasion of Iran. The Iranians had finally became cognizant of the destructive consequences of their factionalism and internecine feuding. {{sfn|Pourshariati|2008|p=234}} [[Al-Tabari]] wrote that after the fall of Ctesiphon "the people... were about to go their separate ways, [but] they started to incite one another: 'If you disperse now, you will never get together again; this is a spot that sends us in different directions'."{{sfn|Pourshariati|2008|pp=234–235}}
 
In 637 Arabs defeated another Sasanian army at the [[Battle of Jalula]], and Yazdegerd fled deeper into [[Media (region)|Media]].{{sfn|Pourshariati|2008|p=235}} He raised a new army there and ordered it to [[Nahavand]] to retake [[Ctesiphon]] in the hope of preventing Muslim advances.{{sfn|Morony|1986|pp=203–210}} The threat presented by the new army prompted [[Umar]] to combine his Arab forces. He ordered [[Al-Nu’man ibn Muqrin]] to take command of the armies of [[Kufa]] and [[Basra]], with additional reinforcements from [[Syria]] and [[Oman]].


In April 637, the Arabs defeated another Sasanian army at the [[Battle of Jalula]]. After this defeat, Yazdegerd fled deeper into [[Media (region)|Media]].{{sfn|Pourshariati|2008|p=235}} He subsequently raised a new army and sent it to [[Nahavand]] to retake [[Ctesiphon]] and prevent any further Muslim advances.{{sfn|Morony|1986|pp=203–210}} The army that Yazdegerd sent seemed such a serious threat that it led [[Umar]] to combine the Arab forces of [[Kufa]] and [[Basra]] under [[Al-Nu'man ibn Muqrin]] and send them against the Sasanians with reinforcements from [[Syria]] and [[Oman]]. The battle is said to have lasted several days. It resulted in major losses on both sides, including the death of [[al-Nu'man ibn Muqrin]] and the Iranian generals [[Mardanshah]] and [[Piruz Khosrow]]. The [[Battle of Nahavand]] in 642 was the second military disaster for the Sasanians after the Battle of al-Qadisiyyah.{{sfn|Morony|1986|pp=203–210}}
In 642 this massive army attacked the Sasanians. The ensuing [[Battle of Nahavand]] is said to have lasted several days, with major losses on both sides.

After the Sasanian disaster, Yazdegerd fled to [[Isfahan]], and raised a small army under a certain military officer named Siyah, who had lost his property to the Arabs. However, Siyah and the rest of the army [[Mutiny|mutinied]] against Yazdegerd, and agreed to help the Arabs in return for places to live.{{sfn|Pourshariati|2008|p=239}} Meanwhile, Yazdegerd had arrived in [[Estakhr]], where he tried organizing a base for resistance in the province of [[Pars Province|Pars]]. However, in 650, [[Abdullah ibn Aamir]], the governor of [[Basra]], invaded Pars and put an end to the Persian resistance. Estakhr was made into ruins after the battle and a force of 40,000 defenders including many Persian nobles were killed. After the Arab conquest of Pars, Yazdegerd fled to [[Kirman (Sasanian province)|Kirman]] while being pursued by an Arab force.{{sfn|Morony|1986|pp=203–210}} Yazdegerd managed to flee from the Arab force in a snowstorm at Bimand.
In the aftermath of the debacle at Nahavand, Yazdegerd fled to [[Isfahan]] where he raised a small army. He placed it under the command of an officer named Siyah who had lost property to the Arabs. But Siyah and his troops also agreed to fight for the Arabs in exchange for places to live {{sfn|Pourshariati|2008|p=239}} and [[Mutiny|mutinied]] against Yazdegerd. Meanwhile, Yazdegerd had arrived in [[Istakhr]] where he tried to establish a base of resistance in [[Pars Province]]. But in 650, the governor of Arab-controlled Basra, [[Abdullah ibn Aamir]], invaded Pars and put an end to the Persian resistance. 40,000 Iranian defenders were slain—many of them nobles—and Istakhr was left in ruins. Following the Arab conquest of Pars, Yazdegerd fled to [[Kirman (Sasanian province)|Kirman]], pursued by an Arab force.{{sfn|Morony|1986|pp=203–210}} Yazdegerd managed to flee from the Arabs in a snowstorm at Bimand.


After arriving at Kirman, Yazdegerd became unfriendly with the ''[[marzban]]'' (general of a frontier province, "[[margrave]]") of Kirman, and then left Kirman for [[Sakastan (Sasanian Province)|Sakastan]]. Another Basran army later arrived which defeated and killed the ''marzban'' of Kirman in a bloody fight. When Yazdegerd arrived at [[Sakastan (Sasanian province)|Sakastan]] he lost the support of the governor of Sakastan by demanding tax from him.{{sfn|Morony|1986|pp=203–210}} Yazdegerd then headed for [[Merv]] to join the leader of the [[Turkic people|Turks]]. However, when he arrived in [[Greater Khorasan|Khorasan]] the inhabitants did not agree with Yazdegerd's decision to continue waging war and told him that it was better if he made peace with the Arabs; Yazdegerd, however, refused. Sakastan was later taken by the Arab forces after a bloody fight around 650–652.{{sfn|Morony|1986|pp=203–210}} Yazdegerd was also supported by the [[Principality of Chaghaniyan]], which sent him troops to aid him against the Arabs. When Yazdegerd arrived in [[Merv|Marw]] (in what is today's [[Turkmenistan]]) he demanded tax from the ''marzban'' of Marw, losing also his support and making him ally with [[Nezak Tarkan]], the [[Hephthalite]] ruler of [[Badghis Province|Badghis]], who helped him defeat Yazdegerd and his followers.
In Kirman, Yazdegerd managed to alienate the ''[[marzban]]'' (frontier military governor or "[[margrave]]"), before leaving for [[Sakastan (Sasanian Province)|Sakastan]]. Then another Arab army from Basra arrived at Kirman. A fierce battle ensued in which the ''marzban'' was slain. And Yazdegerd alienated the governor of [[Sakastan (Sasanian province)|Sakastan]] with his demands for more and higher taxes to fund the army. {{sfn|Morony|1986|pp=203–210}} Yazdegerd next embarked to Merv to meet the leader of the [[Turkic people|Turks]] in the hope of forming an alliance. But when he reached [[Greater Khorasan|Khorasan]], the war-weary populace insisted on peace with the Arabs, and Yazdegerd refused. In 650–652, an Arab army entered Sakastan and captured the city. {{sfn|Morony|1986|pp=203–210}} Yazdegerd did secure the troops from the [[Principality of Chaghaniyan]]. He made the same demands on the ''marzban'' of Merv that he made in Kirman and Sakastsn and met with the same results.  The ''marzban'' joined with [[Nezak Tarkan]], the [[Hephthalite]] ruler of [[Badghis Province|Badghis]], and together they defeated Yazdegerd and his followers.

Template:Short description Script error: No such module "Unsubst".

Script error: No such module "Infobox".Script error: No such module "Check for unknown parameters". Yazdegerd III (also Romanized as Yazdgerd, Yazdgird) was the last Sasanian King of Kings from 632 to 651. His father was Shahriyar and his grandfather was Khosrow II.

Ascending the throne at the age of eight, the young shah lacked authority and reigned as a figurehead, whilst real power was in the hands of the army commanders, courtiers, and powerful members of the aristocracy, who engaged in internecine warfare. The Sasanian Empire was weakened severely by these internal conflicts, resulting in invasions by the Göktürks from the east, and Khazars from the west.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Yazdegerd was unable to contain the Rashidun conquest of Iran, and spent most of his reign fleeing from one province to another in the vain hope of raising an army. Yazdegerd met his end at the hands of a miller near Merv in 651, bringing an end to the last pre-Islamic Iranian empire after more than 400 years of rule.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

Etymology

'Yazdegerd' is a theophoric name that means 'God-made'. It is a combination of the Old Iranian yazad yazata- 'divine being' and karta- 'made'. It is comparable to Persian Bagkart and Greek Theoktistos.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Yazdegerd is known in other languages as follows: Middle PersianYazdekert; New PersianYazd(e)gerd; SyriacYazdegerd, Izdegerd, and Yazdeger; ArmenianYazkert; Talmudic Izdeger and Azger; ArabicYazdeijerd; Greek Isdigerdes.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

Background

Yazdegerd was the son of prince Shahriyar and the grandson of Khosrow II (Template:Reign), the last prominent shah of Iran. Khosrow II had been overthrown and executed in 628 by his own son Sheroe, who took the name Kavad II upon gaining the throne. Kavad then ordered the execution of all his brothers and half-brothers, including Yazdegerd's father Shahriyar.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". The purging of the ranks of the ruling family dealt a blow to the empire from which it would never recover.

The murder of Khosrow II ignited a civil war that lasted four years, as the most powerful members of the nobility created their own autonomous government. Hostilities between the Persian (Parsig) and Parthian (Pahlav) noble families also resumed; they divided the treasury between themselves.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". And months later, a devastating plague swept through the western Sasanian provinces and killed half of the population. Kavad II was one of its victims.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

Kavad was succeeded by his eight-year-old son Ardashir III who was killed two years later by the distinguished Sasanian general Shahrbaraz. Forty days later Shahrbaraz was deposed and murdered by the Pahlav leader Farrukh Hormizd, who installed the daughter of Khosrow II, Boran, on the throne.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".Script error: No such module "Unsubst". She was deposed a year later, and a succession of rulers followed until Boran was sovereign once more in 631, only to be murdered the following year by the Parsig leader Piruz Khosrow.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

Eventually the two most powerful magnates in the empire, Rostam FarrokhzadTemplate:Efn and Piruz Khosrow—threatened by their own men—agreed to ally. They installed Yazdegerd III on the throne, putting an end to the civil war.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". He was crowned in the Temple of Anahita, Istakhr, where he had been hiding during the civil war. The site was chosen to be a symbol of the empire's rejuvenation, as it was the very place where the first Sasanian shah Ardashir I (Template:Reign) had crowned himself four centuries earlier. Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Due to Kavad's massacre of his family, the new shah was among the few surviving members of the House of Sasan.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Most scholars agree that Yazdegerd was eight years old at his coronation.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". His coronation occurred around the same time that Abu Bakr became Caliph.[1]

Early reign and instability

The eight-year-old Yazdegerd lacked the authority needed to bring stability to an empire that was quickly falling apart due to ceaseless internal conflict. Army commanders, courtiers, and powerful members of the aristocracy fought amongst each other in feuds that were often deadly.

Early clash with the Arabs

In 633 Muslim Arabs defeated a Sasanian force under Azadbeh near the strategically important Sasanian city Hira, which the victors then occupied in short order. Yazdegerd's ministers began paying heed to the Muslims after the loss of Hira. Rostam Farrokhzad sent an army commanded by Bahman Jadhuyih and the Armenian Jalinus to face the enemy. Rostam ordered Bahman to return with Jalinus's head if the Armenian general lost. Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". The Sasanian army managed to defeat the Muslims at the Battle of the Bridge.

In 636 Yazdegerd ordered Rostam to subdue the invading Arabs, telling him "Today you are the [most prominent] man among the Iranians...[T]he people of Iran have not faced a situation like this since the family of Ardashir I assumed power."Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

It is not like that. The Arabs and the Persians are comparable to an eagle who looked upon a mountain where birds take shelter at night and stay in their nests at the foot of it. When morning came, the birds looked around and saw that he was watching them. Whenever a bird became separated from the rest, the eagle snatched him.

Last stand

The two armies clashed again 636. The Battle of al-Qadisiyyah resulted in a crushing defeat for the Sasanian army. Rostam, Bahman Jaduya, Jalinus, and the Armenian princes Grigor II Novirak and Mushegh III Mamikonian were all slain in the fighting. The Arabs then headed for the imperial capital Ctesiphon, meeting no resistance along the way. Yazdegerd fled with the treasury and 1,000 servants to Hulwan in Media, leaving Rostam's brother Farrukhzad in charge of the capital. But rather than stay and fight the Arabs, Farrukhzad also fled to Hulwan. The Arabs reached Ctesiphon in 637, besieged the western parts of the city, and soon occupied all of it.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".[2]

In 637 Arabs defeated another Sasanian army at the Battle of Jalula, and Yazdegerd fled deeper into Media.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

Flight

In the aftermath of the debacle at Nahavand, Yazdegerd fled to Isfahan where he raised a small army. He placed it under the command of an officer named Siyah who had lost property to the Arabs. But Siyah and his troops also agreed to fight for the Arabs in exchange for places to live Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". and mutinied against Yazdegerd. Meanwhile, Yazdegerd had arrived in Istakhr where he tried to establish a base of resistance in Pars Province. But in 650, the governor of Arab-controlled Basra, Abdullah ibn Aamir, invaded Pars and put an end to the Persian resistance. 40,000 Iranian defenders were slain—many of them nobles—and Istakhr was left in ruins. Following the Arab conquest of Pars, Yazdegerd fled to Kirman, pursued by an Arab force.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Yazdegerd managed to flee from the Arabs in a snowstorm at Bimand.

In Kirman, Yazdegerd managed to alienate the marzban (frontier military governor or "margrave"), before leaving for Sakastan. Then another Arab army from Basra arrived at Kirman. A fierce battle ensued in which the marzban was slain. And Yazdegerd alienated the governor of Sakastan with his demands for more and higher taxes to fund the army. Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Yazdegerd next embarked to Merv to meet the leader of the Turks in the hope of forming an alliance. But when he reached Khorasan, the war-weary populace insisted on peace with the Arabs, and Yazdegerd refused. In 650–652, an Arab army entered Sakastan and captured the city. Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Yazdegerd did secure the troops from the Principality of Chaghaniyan. He made the same demands on the marzban of Merv that he made in Kirman and Sakastsn and met with the same results. The marzban joined with Nezak Tarkan, the Hephthalite ruler of Badghis, and together they defeated Yazdegerd and his followers.

Chinese assistance

Yazdegerd had sent an envoy to the Chinese emperor seeking assistance in 638 after his first defeat to the Arabs, but nothing seems to have come of the visit.[4] He sent another envoy to the Tang dynasty court in 639 "for offering tribute”.[5] Yazdegerd continued to send envoys to China in 647 and again 648, even as he suffered defeats, in order to “seek assistance from the Chinese court with the hope to form a new army".[5] The Chinese did eventually send assistance, but only after Yazdegerd was dead. His son Peroz III again sent envoys in 654 and 661. Following the second of these embassies, the Chinese established a "Persian military commandery" (波斯都督府) in 661 in the city of Zābol (疾陵城 Jilingcheng) in Tokharistan, and Peroz was appointed as Military Commander (都督 Dudu).[5] In 679 a Chinese army accompanied Narsieh, the exiled son of Peroz, with orders to restore him to the Sasanian throne. But the army was detained in Tokharistan to repel the invasion of Western Turkic Khan Ashina Duzhi, which left Narsieh to fight against the Muslim Arabs without Chinese assistance for the next twenty years.[5] Yazdegard III's grandson Prince Khosrau, son of Bahram VII (recorded as Juluo (Template:Zh) in Chinese sources) attempted to continue his father's military efforts. He is likely the same "Khosrow" mentioned by al-Tabari. Khosrau's campaigns, and his first invasion of Persia, proved unsuccessful.[6]

Death, legacy and personality

After his defeat in 651, Yazdegerd sought refuge with a miller near Merv. Rather than sheltering Yazdegerd, the miller murdered him. According to Kia, the miller killed Yazdegerd for his jewelry,Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". whilst The Cambridge History of Iran states that the miller was sent by Mahoe Suri.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

The death of Yazdegerd marked the end of the Sasanian Empire, and made it easier for the Arabs to conquer the rest of Iran. All of Khorasan was soon conquered by the Arabs, who would use it as a base to attack Transoxiana.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". The death of Yazdegerd thus marked the end of the last pre-Islamic Iranian empire after more than 400 years of rule. The empire—which had a generation earlier conquered Egypt and Asia Minor, reaching as a far as Constantinople—fell to a force of lightly-equipped Arabs used to skirmishes and desert warfare. The heavy Sasanian cavalry was too sluggish and systematized to contain them; employing light-armed Arab or East Iranian mercenaries from Khorasan and Transoxiana would have been more effective.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

Yazdegerd was according to tradition buried by Christian monks in Merv, in a tall tomb situated in a garden and decorated with silk and musk. A funeral and mausoleum were organized by Church of the East bishop Elias of Merv in honor of Yazdegerd's Christian grandmother Shirin. For his part in the murder of the Sassanian king, Mahoe had his arms, legs, ears and nose cut off by the Turks, who eventually left him to die under the scorching summer sun. The corpse of Mahoe was then burned at the stake, along with the bodies of his three sons.[7]

According to one tradition, the monks cursed Mahoe and made a hymn to Yazdegerd, mourning the fall of a "combative" king and the "house of Ardashir I".Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Whether the tradition was factual or not, it emphasizes that the Christians of the empire remained loyal to the Zoroastrian Sasanians, even possibly more than the Iranian nobles who had deserted Yazdegerd.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Indeed, there were close links between the late Sasanian rulers and Christians, whose conditions had greatly improved compared to that of the early Sasanian era. Yazdegerd's wife was according to folklore a Christian, whilst his son and heir, Peroz III was seemingly an adherent of Christianity, and had a church built in China where he had taken refuge.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Yazdegerd became remembered in history as a martyred prince; many rulers and officers of Islamic Iran would claim descent from him.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".

Yazdegerd was well-educated and cultured, but his arrogance, pride and inability to compare his demands with the real situation led to his constantly falling out with his governors and to his influence diminishing as he, pursued by Arabs, moved from one city to another. At each new place, he behaved as if he was still the all-powerful monarch of the kingdom and not an outcast running away from enemies. Combined with his military failures, this arrogance turned many of his most loyal subjects away from him.[8]

Zoroastrian calendar

The Zoroastrian religious calendar, which is still in use today, uses the regnal year of Yazdegerd III as its base year,[9] and its calendar era (year numbering system) is accompanied by a Y.Z. suffix.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters".
