Dozens of pre-historic sites across the Iranian plateau point to the existence of ancient cultures and urban settlements in the fourth millennium BC, centuries before the earliest civilizations arose in nearby Mesopotamia. Proto-Iranians first emerged following the separation of Indo-Iranians, and are traced to the Bactria-Margiana Archaeological Complex. Aryan (Proto-Iranian) tribes arrived in the Iranian plateau in the third and second millennium BC, probably in more than one wave of emigration, and settled as nomads. Further separation of Proto-Iranians into "Eastern" and "Western" groups occurred due to migration. By the first millennium BC, Medes, Persians, Bactrians and Parthians populated the western part, while Cimmerians, Sarmatians and Alans populated the steppes north of the Black Sea. Other tribes began to settle on the eastern edge, as far as on the mountainous frontier of north-western Indian subcontinent and into the area which is now Balochistan. Others, such as the Scythian tribes spread as far west as the Balkans and as far east as Xinjiang. Avestan is an eastern Old Iranian language that was used to compose the sacred hymns and canon of the Zoroastrian Gathas in c. 1000 BC.
The Medes are credited with the unification of Iran as a nation and
empire (625–559 BC), the largest of its day, until Cyrus the Great
established a unified empire of the Medes and Persians leading to the
Achaemenid Empire (559–330 BC), and further unification between
peoples and cultures. After Cyrus' death, his son Cambyses continued
his father's work of conquest, making significant gains in Egypt.
Following a power struggle after Cambyses' death, Darius I was declared
king (ruled 522–486 BC). Under Cyrus the Great and Darius the Great,
the Persian Empire eventually became the largest and most powerful
empire in human history up until that point.The borders of the Persian
empire stretched from the Indus and Oxus Rivers in the east to the
Mediterranean Sea in the west, extending through Anatolia (modern day
Turkey) and Egypt.
The Achaemenid Empire at its greatest extent, at about 500 BC
In
499 BC Athens lent support to a revolt in Miletus which resulted in the
sacking of Sardis. This led to an Achaemenid campaign against Greece
known as the Greco-Persian Wars which lasted the first half of the 5th
century BC. During the Greco-Persian wars Persia made some major
advantages and razed Athens in 480 BC, But after a string of Greek
victories the Persians were forced to withdraw. Fighting ended with the
peace of Callias in 449 BC.
The rules and ethics emanating
from Zoroaster's teachings were strictly followed by the Achaemenids
who introduced and adopted policies based on human rights, equality and
banning of slavery. Zoroastrianism spread unimposed during the time of
the Achaemenids and through contacts with the exiled Jewish people in
Babylon freed by Cyrus, Zoroastrian concepts further propagated and
influenced the Abrahamic religions. The Golden Age of Athens marked by
Aristotle, Plato and Socrates also came about during the Achaemenid
period while their contacts with Persia and the Near East abounded. The
peace, tranquility, security and prosperity that were afforded to the
people of the Near East and Southeastern Europe proved to be a rare
historical occurrence, an unparalleled period where commerce prospered,
and the standard of living for all people of the region improved.
In
334 BC, Alexander the Macedonian invaded the Achaemenid Empire,
defeating the last Achaemenid Emperor Darius III at the Battle of Issus
in 333 BC. He left the annexed territory in 328–327. In each of the
former Achaemenid territories he installed his own officers as
caretakers, which led to friction and ultimately to the partitioning of
the former empire after Alexander's death.
The
Parthian Empire (238 BC–226 AD), led by the Arsacid Dynasty, was the
third Iranian kingdom to dominate the Iranian plateau, after defeating
the Greek Seleucid Empire, beginning in the late 3rd century BC, and
intermittently controlled Mesopotamia between ca. 150 BC and 224 AD.
These were the third native dynasty of ancient Iran and lasted five
centuries. After the conquests of Media, Assyria, Babylonia and Elam,
the Parthians had to organize their empire. The former elites of these
countries were Greek, and the new rulers had to adapt to their customs
if they wanted their rule to last. As a result, the cities retained
their ancient rights and civil administrations remained more or less
undisturbed.
Parthia was the arch-enemy of the Roman Empire in
the east, limiting Rome's expansion beyond Cappadocia (central
Anatolia). By using a heavily armed and armoured cataphract cavalry,
and lightly armed but highly mobile mounted archers, the Parthians
"held their own against Rome for almost 300 years".Rome's acclaimed
general Mark Antony led a disastrous campaign against the Parthians in
36 BC, in which he lost 32,000 men. By the time of Roman emperor
Augustus, Rome and Parthia were settling some of their differences
through diplomacy. By this time, Parthia had acquired an assortment of
golden eagles, the cherished standards of Rome's legions, captured from
Mark Antony, and Crassus, who suffered a defeat at Carrhae in 53 BC.
The
end of the Parthian Empire came in 224 AD, when the empire was loosely
organized and the last king was defeated by Ardashir I, one of the
empire's vassals. Ardashir I then went on to create the Sassanid
Empire. Soon he started reforming the country both economically and
militarily. The Sassanids established an empire roughly within the
frontiers achieved by the Achaemenids, referring to it as Erânshahr or
Iranshahr, , "Dominion of the Aryans", (i.e. of Iranians), with their
capital at Ctesiphon.Unlike the diadochic Seleucids and the succeeding
Arsacids, who used a vassalary system, the Sassanids—like the
Achaemenids—had a system of governors (MP: shahrab) personally
appointed by the Emperor and directed by the central government.
The
Romans suffered repeated losses particularly by Ardashir I, Shapur I,
and Shapur II.[49] During their reign, Sassanid battles with the Roman
Empire caused such pessimism in Rome that the historian Cassius Dio
wrote:
“ Here was a source of great fear to us. So formidable does
the Sassanid king seem to our eastern legions, that some are liable to
go over to him, and others are unwilling to fight at all.”
In
632 raiders from the Arab peninsula began attacking the Sassanid
Empire. Iran was defeated in the Battle of al-Qâdisiyah, paving way for
the Islamic conquest of Persia.
During Parthian, and
later Sassanid era, trade on the Silk Road was a significant factor in
the development of the great civilizations of China, Egypt,
Mesopotamia, Persia, Indian subcontinent, and Rome, and helped to lay
the foundations for the modern world. Parthian remains display
classical Greek influences in some instances and retain their oriental
mode in others, a clear expression of the cultural diversity that
characterized Parthian art and life.The Parthians were innovators of
many architecture designs such as that of Ctesiphon, which later
influenced European Romanesque architecture.Under the Sassanids, Iran
expanded relations with China. Arts, music, and architecture greatly
flourished, and centers such as the School of Nisibis and Academy of
Gundishapur became world renowned centers of science and scholarship.
Iran after the Islamic conquest of Persia
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.
Middle Ages (652–1501)
After
the Islamic conquest of Persia, most of the urban lands of the Sassanid
empire with the exception of Caspian provinces and Transoxiana came
under Islamic rule. Many provinces in Iran defended themselves against
the Arab invaders, although none in the end was able to repulse the
invaders. However, when the Arabs had subdued the country, many of the
cities rose in rebellions, killing Arab governors, although
reinforcement by Arab armies succeeded in putting down the rebellions.
However, the Iranians' conversion to Islam was a complex process, which
is generally considered a gradual process and the notion of force has
largely been discredited , although occasional acts of violence did
take place, with Zoroastrian scriptures getting burned and Zoroastrian
priests getting executed By 9th century, Islam became a dominant
religion in Persia and the conversion of Iranians to Islam brought
profound changes in their life and culture. However in some regions,
like Fars province, Zoroastrianism was strong up to the 9th century,
although Sufis like Abu Eshaq Kazeruni, the founder of Kazeruni Sufi
order brought mass conversion of Zoroastrians to Islam in the 10th
century.
During the Abbasid caliphate decline, independent and
semi-independent native Iranian dynasties arose in different parts of
Persia including the Tahirids, Saffarids, Samanids, Afrighids,Ghurids,
Sallarid, Justanids, Shaddadids and Buyids. Socially, the Arabs
abolished the previous social class system of Sassanians <while
later, especially under the Ummayyads, another form of discrimination
and exclusion against non-Arabs evolved[59]. In reaction to these, Abu
Moslem, an Iranian general, expelled the Umayyads from Damascus and
helped the Abbasid caliphs to conquer Baghdad. The Abbasid caliphs
frequently chose their "wazirs" (viziers) among Iranians, and Iranian
governors acquired a certain amount of local autonomy. Thus in 822, the
governor of Khorasan, Tahir, proclaimed his independence and founded a
new Persian dynasty of Tahirids. And by the Samanid era, Iran's efforts
to regain its independence had been well solidified.
Attempts
of Arabization thus never succeeded in Iran, and movements such as the
Shuubiyah became catalysts for Iranians to regain their independence in
their relations with the Arab invaders[63]. Other notable major
revolts, some by Iranian Muslims and others by practitioners of old
Iranian religions against Arab rule were lead by Al-Muqanna, Sunpadh,
Khurramites, Babak Khorramdin, Maziar, Mardavij, Ustadh Sis and
Ya'qub-i Laith Saffari.
The cultural revival of the post-Abbasid
period led to a resurfacing of Iranian national identity. The resulting
cultural movement reached its peak during the 9th and 10th centuries.
The most notable effect of the movement was the continuation of the
Persian language, the language of the Persians and the official
language of Iran to the present day. Ferdowsi, Iran's greatest epic
poet, is regarded today as the most important figure in maintaining the
Persian language. After an interval of silence Iran re-emerged as a
separate, different and distinctive element within Islam.
In
1218, the eastern Khwarazmid provinces of Transoxiana and Khorasan
suffered a devastating invasion by Genghis Khan. During this period
more than half of Iran's population was killed, turning the streets of
Persian cities such as Neishabur into "rivers of blood", as the severed
heads of men, women, and children were "neatly stacked into carefully
constructed pyramids around which the carcasses of the city's dogs and
cats were placed". Between 1220 and 1260, the total population of Iran
had dropped from 2,500,000 to 250,000 as a result of mass extermination
and famine. In a letter to King Louis IX of France, Holaku, one of the
Genghis Khan's grandsons, alone took responsibility for 200,000 deaths
in his raids of Iran and the Caliphate. He was followed by yet another
conqueror, Tamerlane, who established his capital in Samarkand. The
waves of devastation prevented many cities such as Neishabur from
reaching their pre-invasion population levels until the 20th century,
eight centuries later. But both Hulagu, Tamerlane, and their successors
soon came to adopt the ways and customs of that which they had
conquered, choosing to surround themselves with a culture that was
distinctively Persian.
Early modern era (1501–1921)
Iran's
first encompassing Shi'a Islamic state was established under the
Safavid Dynasty (1501–1722) by Shah Ismail I. The Safavid Dynasty soon
became a major political power and promoted the flow of bilateral state
contacts. The Safavid peak was during the rule of Shah Abbas The
Great.[19] The Safavid Dynasty frequently warred with the Ottoman
Empire, Uzbek tribes and the Portuguese Empire. The Safavids moved
their capital from Tabriz to Qazvin and then to Isfahan, where their
patronage for the arts propelled Iran into one of its most
aesthetically productive eras. Under their rule, the state became
highly centralized, the first attempts to modernize the military were
made, and even a distinct style of architecture developed. In 1722
Afghan rebels defeated Shah Sultan Hossein and ended the Safavid
Dynasty, but in 1735, Nader Shah successfully drove out the Afghan
rebels from Isfahan and established the Afsharid Dynasty. He then
staged an incursion into India in 1738, securing the Peacock throne,
Koh-i-Noor, and Darya-ye Noor among other royal treasures. His rule did
not last long, however, as he was assassinated in 1747. The Mashhad
based Afshar Dynasty was succeeded by the Zand dynasty in 1750, founded
by Karim Khan, who established his capital at Shiraz. His rule brought
a period of relative peace and renewed prosperity.
The Zand
dynasty lasted three generations, until Aga Muhammad Khan executed Lotf
Ali Khan, and founded his new capital in Tehran, marking the dawn of
the Qajar Dynasty in 1794. The Qajar chancellor Amir Kabir established
Iran's first modern college system, among other modernizing reforms.
Iran suffered several wars with Imperial Russia during the Qajar era,
resulting in Iran losing almost half of its territories to Imperial
Russia and the British Empire, via the treaties of Gulistan,
Turkmenchay and Akhal. In spite of The Great Game Iran managed to
maintain her sovereignty and was never colonized, unlike neighbouring
states in the region. Repeated foreign intervention and a corrupt and
weakened Qajar rule led to various protests, which by the end of the
Qajar period resulted in Persia's constitutional revolution
establishing the nation's first parliament in 1906, within a
constitutional monarchy. Persia had Persian Campaign in World War One.
Recent history (1921–present)
In
1925, Reza Khan overthrew the weakening Qajar Dynasty and became Shah.
Reza Shah initiated industrialization, railroad construction, and the
establishment of a national education system. Reza Shah sought to
balance Russian and British influence, but when World War II started,
his nascent ties to Germany alarmed Britain and Russia. In 1941,
Britain and the USSR invaded Iran to use Iranian railroad capacity
during World War II. The Shah was forced to abdicate in favour of his
son, Mohammad Reza Pahlavi.
In 1951 Dr. Mohammed Mossadegh
was elected prime minister. As prime minister, Mossadegh became
enormously popular in Iran after he nationalized Iran's oil reserves.
In response, Britain embargoed Iranian oil and, amidst Cold War fears,
invited the United States to join in a plot to depose Mossadegh, and in
1953 President Dwight D. Eisenhower authorized Operation Ajax. The
operation was successful, and Mossadegh was arrested on 19 August 1953.
After Operation Ajax, Mohammad Reza Pahlavi's rule became increasingly
autocratic. With American support, the Shah was able to rapidly
modernize Iranian infrastructure, but he simultaneously crushed all
forms of political opposition with his intelligence agency, SAVAK.
Ayatollah Ruhollah Khomeini became an active critic of the Shah's White
Revolution and publicly denounced the government. Khomeini was arrested
and imprisoned for 18 months. After his release in 1964 Khomeini
publicly criticized the United States government. The Shah was
persuaded to send him into exile by General Hassan Pakravan. Khomeini
was sent first to Turkey, then to Iraq and finally to France. While in
exile, he continued to denounce the Shah.
The Iranian Revolution,
also known as the Islamic Revolution, began in January 1978 with the
first major demonstrations against the Shah. After strikes and
demonstrations paralysed the country and its economy, the Shah fled the
country in January 1979 and Ayatollah Khomeini returned from exile to
Tehran. The Pahlavi Dynasty collapsed ten days later, on 11 February,
when Iran's military declared itself "neutral" after guerrillas and
rebel troops overwhelmed troops loyal to the Shah in armed street
fighting. Iran officially became an Islamic Republic on 1 April 1979
when Iranians overwhelmingly approved a national referendum to make it
so. In December 1979, the country approved a theocratic constitution,
whereby Khomeini became Supreme Leader of the country. The speed and
success of the revolution surprised many throughout the world, as it
had not been precipitated by a military defeat, a financial crisis, or
a peasant rebellion. Although both nationalists and Marxists joined
with Islamic traditionalists to overthrow the Shah, tens of thousands
were killed and executed by the Islamic regime afterward, the
revolution ultimately resulted in an Islamic Republic under Ayatollah
Ruhollah Khomeini.
Iran's relationship with the United
States deteriorated rapidly during the revolution. On 4 November 1979,
a group of Iranian students seized US embassy personnel, labelling the
embassy a "den of spies". They accused its personnel of being CIA
agents plotting to overthrow the revolutionary government, as the CIA
had done to Mohammad Mossadegh in 1953. While the student ringleaders
had not asked for permission from Khomeini to seize the embassy,
Khomeini nonetheless supported the embassy takeover after hearing of
its success. While most of the female and African American hostages
were released within the first months, the remaining fifty-two hostages
were held for 444 days. Subsequently attempts by the Jimmy Carter
administration to negotiate or rescue were unsuccessful. In January
1981 the hostages were set free according to the Algiers declaration.
Iraqi
leader Saddam Hussein decided to take advantage of what he perceived to
be disorder in the wake of the Iranian Revolution and its unpopularity
with Western governments. The once-strong Iranian military had been
disbanded during the revolution. Saddam sought to expand Iraq's access
to the Persian Gulf by acquiring territories that Iraq had claimed
earlier from Iran during the Shah's rule. Of chief importance to Iraq
was Khuzestan which not only has a substantial Arab population, but
boasted rich oil fields as well. On the unilateral behalf of the United
Arab Emirates, the islands of Abu Musa and the Greater and Lesser Tunbs
became objectives as well. On 22 September 1980 the Iraqi army invaded
Iran at Khuzestan, precipitating the Iran–Iraq War.
Although
Saddam Hussein's forces made several early advances, by 1982, Iranian
forces managed to push the Iraqi army back into Iraq. Khomeini sought
to export his Islamic revolution westward into Iraq, especially on the
majority Shi'a Arabs living in the country. The war then continued for
six more years until 1988, when Khomeini, in his words, "drank the cup
of poison" and accepted a truce mediated by the United Nations. The
total Iranian casualties of the war were estimated to be anywhere
between 500,000 and 1,000,000; with more than 100,000 Iranians being
victims of Iraq's chemical weapons. Almost all relevant international
agencies have confirmed that Saddam engaged in chemical warfare to
blunt Iranian human wave attacks; these agencies unanimously confirmed
that Iran never used chemical weapons during the war.
Following
the Iran–Iraq War President Akbar Hashemi Rafsanjani and his
administration concentrated on a pragmatic pro-business policy of
rebuilding and strengthening the economy without making any dramatic
break with the ideology of the revolution. Rafsanjani served until 1997
when he was succeeded by the moderate reformist Mohammad Khatami.
During his two terms as president, Khatami advocated freedom of
expression, tolerance and civil society, constructive diplomatic
relations with other states including EU and Asian governments, and an
economic policy that supported free market and foreign investment.
However, Khatami is widely regarded as having been unsuccessful in
achieving his goal of making Iran more free and democratic. In the 2005
presidential elections, Iran made yet another change in political
direction, when conservative populist candidate Mahmoud Ahmadinejad was
elected over Akbar Hashemi Rafsanjani.
