The Islamic conquest of Persia (633–656) led to the end of the Sassanid Persian Empire and the eventual extirpation of the Zoroastrian religion in Persia. Most Muslim historians have long offered the idea that Persia, on the verge of the Arab invasion, was a society in decline and decay and thus it embraced the invading Arab armies with open arms. This view is not widely accepted however. Some authors have for example used mostly Arab sources to illustrate that "contrary to the claims of Muslim apologists, Iranians in fact fought long and hard against the invading Arabs." This view further more holds that once politically conquered, the Persians began engaging in a culture war of resistance and succeeded in forcing their own ways on the Arabs.
As Bernard Lewis has quoted;
"These
events have been variously seen in Iran: by some as a blessing, the
advent of the true faith, the end of the age of ignorance and
heathenism; by others as a humiliating national defeat, the conquest
and subjugation of the country by foreign invaders. Both perceptions
are of course valid, depending on one's angle of vision."
Den islamiske erobring af Persien (633-656) førte til udgangen af Sassanid persiske imperium og eventuel extirpation af Zoroastrian religion i Persien. Men resultaterne fra det tidligere persiske civilisationer ikke var gået tabt, men blev i høj grad optaget af de nye islamiske samfundsdannelse.
Persia Before the Conquest
Since the 1st century BC,
the border between the Roman (later Byzantine) and Parthian (later
Sassanid dynastic) empires had been the Euphrates river. The border was
constantly contested. Most battles, and thus most fortifications, were
concentrated in the hilly regions of the north, as the vast Arabian or
Syrian Desert (Roman Arabia) separated the rival empires in the south.
The only dangers expected from the south were occasional raids by
nomadic Arab tribesmen. Both empires therefore allied themselves with
small, semi-independent Arab principalities, which served as buffer
states and protected Byzantium and Persia from Bedouin attacks. The
Byzantine clients were the Ghassanids; the Persian clients were the
Lakhmids. The Ghassanids and Lakhmids feuded constantly — which kept
them occupied, but did not greatly affect the Byzantines or Persians.
In the 6th and 7th centuries, various factors destroyed the balance of power that had held for so many centuries.
Balance Between Persia and Byzantium Swings Wildly
The
Persian ruler Khusrau II (Parviz) defeated a dangerous rebellion within
his own empire (the Bahram Chobin's rebellion). He afterwards turned
his energies outwards, upon the traditional Byzantine enemies in the
Roman-Persian Wars. For a few years, he succeeded gloriously. From 612
to 622, he extended the Persian borders almost to the same extent that
they were under the Achaemenid dynasty(550–330 BC), capturing cities of
Antioch, Damascus, Alexandria, and Jerusalem.
The
Byzantines regrouped and pushed back in 622 under Heraclius. Khusrau
was defeated at the Battle of Nineveh in 627, and the Byzantines
recaptured all of Syria and penetrated far into the Persian provinces
of Mesopotamia. In 629, Khusrau's son agreed to peace, and the border
between the two empires was once again the same as it was in 602.
Assassination of Khusrau II and a Succession of Weak Rulers
Khusrau
II was assassinated in 628 and as a result, there were numerous
claimants to the throne; from 628 to 632 there were ten kings and
queens of Persia. The last, Yazdegerd III, was a grandson of Khusrau II
and was said to be a mere child. However, no date of birth is known.
Revolt of the Arab Client States
The
Byzantine clients, the Arab Ghassanids, converted to the Monophysite
form of Christianity, which was regarded as heretical by the
established Byzantine Orthodox Church. The Byzantines attempted to
suppress the heresy, alienating the Ghassanids and sparking rebellions
on their desert frontiers.
The Lakhmids also revolted against
the Persian king Khusrau II. Al-Noman III (son of Al-Monder IV), the
first Christian Lakhmid king, was deposed and killed by Khusrau II,
because of his attempt to throw off the Persian tutelage. After
Khusrau's assassination, the Persian Empire fractured and the Lakhmids
were effectively semi-independent.
It is tenable that weakening
the Lakhmids and the Ghassanids bulwark contributed to the consequent
Arab-Muslim breakthrough into what is today known as Iraq and Jordan.
During Prophet Muhammad's Life
After
the Treaty of Hudaybiyyah in 628, the Prophet Muhammad sent many
letters to the princes, kings and chiefs of the various tribes and
kingdoms of the time inviting them to convert to Islam. These letters
were carried by ambassadors to Iran, Byzantium, Ethiopia, Egypt, Yemen,
and Hira (Iraq) on the same day. This assertion has been cast into
scrutiny by some modern historians of Islam--notably Grimme and
Caetani. Particularly in dispute is the assertion that Khosrau II
received a letter from Muhammad, as the Sassanid court ceremony was
notoriously intricate, and it is unlikely that a letter from what at
the time was a minor regional power would have reached the hands of the
Shahanshah.
With regards to Iran, Muslim histories further
re-count that at the beginning of the seventh year of migration,
Muhammad appointed one of his officers, Abdullah Huzafah Sahmi Qarashi,
to carry his letter to Khosrau II inviting him to Islam:
"In
the name of God, the Beneficent, the Merciful. From Muhammad, the
Messenger of God, to the great Kisra of Iran. Peace be upon him, who
seeks truth and expresses belief in God and in His Prophet and
testifies that there is no god but God and that He has no partner, and
who believes that Muhammad is His servant and Prophet. Under the
Command of God, I invite you to Him. He has sent me for the guidance of
all people so that I may warn them all of His wrath and may present the
unbelievers with an ultimatum. Embrace Islam so that you may remain
safe. And if you refuse to accept Islam, you will be responsible for
the sins of the Magi."
There are differing accounts of
the reaction of Khosrau II. Nearly all assert that he destroyed the
letter in anger; the variations concentrate on the extent and detail of
his response.
Rise of the Islamic Empire
By the
time of Muhammad's death in 632, most of what is now considered Arabia
was united under the new religion of Islam. However, as Fred Donner
argues in his 1981 book, The Early Islamic Conquests, Arabic-speaking
nomads or villagers roamed over or settled on the edge of the Syrian
steppe as well. Any regime that aimed to unite all Arabs would have to
conquer the Syrian steppe. Under Muhammad's successor Abu Bakr, the
first caliph, the Muslims first re-established their control over
Arabia (the Ridda Wars) and then launched campaigns against the
remaining Arabs of Syria and Palestine.
However, this put the
nascent Islamic empire on a collision course with the Byzantine and
Sassanid empires, which had been disputing these territories for
centuries. The wars soon became a matter of conquest, rather than mere
consolidation of the Arab tribes.
