After the Revolution, the composition of the middle class in Iran did not change significantly, but its size doubled from about 15 percent of the population in 1979 to more than 32 percent in 2000.^[1]

Classes in Iran have been divided up into upper class, propertied middle class, salaried middle class, working class, independent farmers, rural wage earners.^[2] A more recent source^[1] divides Iranian classes into upper, middle class (about 32% of the population in 2000),^[1] working class (about 45% of the labor force)^[1], and lower class.

In the post-revolutionary era, access to political power, an important basis for measuring influence and elite status in prerevolutionary Iran, has continued to be important for ascribing status, even though the composition of the political elite has changed. For 10 years after 1979, gaining entry to the political elite at the national or provincial level depended on having revolutionary credentials, that is, being able to provide evidence of having participated in the demonstrations and other revolutionary activities during 1978–79, and having a reputation for being a good Muslim, that is, attending public prayers and observing Islamic codes of conduct in one’s private life. Revolutionary credentials became less significant for the generation that matured after the early 1990s. Education, especially a college degree, became an informal substitute for revolutionary credentials.^[1]

The upper class[link]

The postrevolutionary upper class consisted of some of the same social groups as the old elite, such as large landowners, industrialists, financiers, and large-scale merchants. Most of these groups have migrated out of Iran and their assets confiscated by the state. A minority of the pre-revolutionary upper class continue to work and live within Iran. For the most part, however, such persons did not occupy positions of political influence. Those with political influence comprised senior clergy, high-ranking bureaucrats, executive officers of public and private corporations and charitable foundations, and wealthy entrepreneurs; none had been part of the prerevolutionary economic and social elite. Although a reputation for piety and loyalty to the ideals of the Revolution initially was a more important attribute than family or wealth for participation in the postrevolutionary political elite, those who attained politically powerful positions received generous salaries that elevated them to the top income brackets and opened access to multiple legitimate opportunities for acquiring more wealth. The children of the new elite generally have been encouraged to get college educations, and postgraduate degrees from foreign universities have become status symbols since the mid-1990s. These social trends have gradually but informally altered the criteria for recruitment into the political elite: Possessing a university degree and having ties to a prominent religious or revolutionary family have become advantageous in the competition for politically influential positions.^[1]

The middle class[link]

After the Revolution, the composition of the middle class did not change significantly, but its size doubled from about 15 percent of the population in 1979 to more than 32 percent in 2000. Several prerevolutionary social groups still were identifiable, including entrepreneurs, bazaar merchants, physicians, engineers, university teachers, managers of private and public concerns, civil servants, teachers, medium-scale landowners, junior military officers, and the middle ranks of the Shia clergy. New groups also emerged, including technicians in specialized fields such as communications, computers, electronics, and medical services; owners of small-scale factories employing fewer than 50 workers; owners of construction firms and transport companies; and professional staff of broadcast and print media. Merchants, especially those with ties to bazaar-based organizations even though their stores were physically located outside the traditional covered bazaars, gained access to political power that they had lacked before the Revolution.^[1]

The prerevolutionary cultural divide between those middle-class individuals who had a secular outlook and those who valued a role for religion in both public and private life did not disappear. Since 1979, however, the political relationship between these two contrasting views has reversed. Whereas under the monarchy the state tried to restrict religion to the private sphere, under the Islamic Republic the state consciously has promoted religion in public life. Secularly oriented Iranians have tended to resent this dominant role of the religious outlook in politics and society, especially its manifestations in numerous laws and regulations that they perceive as interfering with their personal lives. Whereas the secular-religious divide cuts across all occupational groups, in general those who promote religious values and the public observance of prayers and religious rituals tend to be more heavily concentrated in the bazaar, security forces, and managerial positions in the bureaucracies than in other lines of work and other professions.^[1]

The working class[link]

An urban industrial working class separate from the traditional artisan class of the towns has been in the process of formation since the early twentieth century. The industrialization programs of the Pahlavi shahs provided the impetus for the expansion of this class. By the early 1970s, a distinct working-class identity, 'kargar', had emerged, although those who applied this term to themselves did not constitute a unified group. Rather, the working class was segmented by economic sectors: the oil industry, manufacturing, construction, and transportation; also, many members of the working class were employed as mechanics. The largest component, factory workers, numbered about 2.5 million on the eve of the Revolution, double the number in 1965, accounting for 25 percent of Iran's total labor force.^[1]

Since 1979, the urban working class has continued to expand; by the early 2000s, it constituted more than 45 percent of the employed labor force. As was the situation before the Revolution, however, the workers within any one occupation did not share a common identity but rather were divided according to their perceived skills. For example, skilled construction workers, such as carpenters, electricians, and plumbers, earned significantly higher wages than the more numerous unskilled workers and tended to look down on them. Similar status differences were common among workers in the oil industry and manufacturing. An estimated 7 percent of all workers were Afghan refugees in the early 2000s. These workers were concentrated in unskilled jobs, especially in construction. Because most Afghan workers did not have work permits after 1992 and thus worked illegally, employers could pay them less than the daily minimum wage rates and not provide them with benefits required for Iranian workers.^[1]

Under both the monarchy and the republic, the government has strictly controlled union activity. After the Revolution, the Ministry of Labor established the Workers’ House to sponsor Islamic unions in large manufacturing concerns. These unions discourage strikes through a combination of cooptation of workers through periodic raises and bonuses and cooperation with authorities to identify and discipline workers who exhibit tendencies toward independence. The Islamic unions generally have been effective in preventing major strikes by workers; a long history of factionalism among different working-class occupational groups and between skilled and unskilled workers within individual industries has contributed to this relative success. Nevertheless, since the early 1990s scattered strikes have defied union control. In some instances, the strikes have been resolved peacefully through negotiations, while in other cases they have been repressed violently by security forces.^[1]

The lower class[link]

The working class is part of the overall urban lower class, or mostazafin, a social stratum that includes all families whose household incomes place them marginally above, at, or below the officially defined poverty line. In cities with populations greater than 250,000, the lower class makes up an average of 40 to 50 percent of the total population; the lower-class proportion generally is less in smaller cities (50,000 to 250,000 population) and towns.^[1][3]

The lower class can be divided into two groups: the marginally poor, who receive regular incomes on a weekly or monthly basis; and the very poor, whose incomes vary from month to month and who thus experience difficulty in paying for food, housing, and utilities. Recipients of regular incomes include pensioners, industrial and construction workers, and people employed in the diverse services sector, such as attendants in barbershops, beauty salons, and public bathhouses, bakery workers, sales clerks, domestic servants, gardeners, garbage and trash collectors, painters and plasterers (of homes), porters, street cleaners, peddlers, street vendors, office cleaners, and laundry workers. These job categories, as well as others, also include at least 1 million workers who are employed only occasionally or seasonally, primarily as a result of the shortage of full-time positions in an economy that has had an official unemployment rate ranging between 10 and 15 percent of the labor force since the early 1990s.^[4] Although many government agencies and private charities provide assistance to the poor, a social stigma is associated with accepting such aid, especially among adult men, whom others judge according to their ability to support a family. Among some marginally poor people in the largest cites, especially families with female heads of household, there has been an increasing tendency since the mid-1990s to rely on begging to supplement income, A few poor neighborhoods in the largest cities, such as 'Khakh-e sefid' in southeasten Tehran Province, have acquired negative reputations because gangs have established safe houses there for illegal activities such as prostitution, gambling, and drug trafficking.^[1]

Iran (ⁱ/ɪˈrɑːn/^[9] or /aɪˈræn/;^[10] Persian: ایران‎ [ʔiˈɾɒn] ( listen)), officially the Islamic Republic of Iran (Persian: جمهوری اسلامی ایران‎ Jomhuri-ye Eslāmi-ye Irān), is a country in Southern and Western Asia.^[11][12] The name "Iran", which in Persian means "Land of the Aryans", has been in use natively since the Sassanian era. It came into use internationally in 1935, before which the country was known to the Western world as Persia ( /ˈpɜrʒə/ or /ˈpɜrʃə/).^[10][13] Both "Persia" and "Iran" are used interchangeably in cultural contexts; however, "Iran" is the name used officially in political contexts.^[14][15]

The 18th-largest country in the world in terms of area at 1,648,195 km² (636,372 sq mi), Iran has a population of around 79 million.^[5] It is a country of particular geopolitical significance owing to its location in the Middle East and central Eurasia. Iran is bordered on the north by Armenia, Azerbaijan and Turkmenistan. As Iran is a littoral state of the Caspian Sea, which is an inland sea, Kazakhstan and Russia are also Iran's direct neighbors to the north. Iran is bordered on the east by Afghanistan and Pakistan, on the south by the Persian Gulf and the Gulf of Oman, on the west by Iraq and on the northwest by Turkey. Tehran is the capital, the country's largest city and the political, cultural, commercial and industrial center of the nation. Iran is a regional power,^[16][17] and holds an important position in international energy security and world economy as a result of its large reserves of petroleum and natural gas. Iran has the second largest proven natural gas reserves in the world and the fourth largest proven petroleum reserves.^[18]

Iran is home to one of the world's oldest civilizations.^[19] The first dynasty in Iran formed during the Elamite kingdom in 2800 BC. The Iranian Medes unified Iran into an empire in 625 BC.^[3] They were succeeded by the Iranian Achaemenid Empire, the Hellenic Seleucid Empire and two subsequent Iranian empires, the Parthians and the Sassanids, before the Muslim conquest in 651 AD. Iranian post-Islamic dynasties and empires expanded the Persian language and culture throughout the Iranian plateau. Early Iranian dynasties which re-asserted Iranian independence included the Tahirids, Saffarids, Samanids and Buyids.

The blossoming of Persian literature, philosophy, medicine, astronomy, mathematics and art became major elements of Muslim civilization. Iranian identity continued despite foreign rule in the ensuing centuries^[20] and Persian culture was adopted also by the Ghaznavids,^[21] Seljuk,^[22][23] Ilkhanid^[24] and Timurid^[25] rulers. The emergence in 1501 of the Safavid dynasty,^[4] which promoted Twelver Shia Islam^[26] as the official religion of their empire, marked one of the most important turning points in Iranian and Muslim history.^[27] The Persian Constitutional Revolution established the nation's first parliament in 1906, within a constitutional monarchy. In 1953 Iran became an authoritarian regime, following a coup d'état instigated by the UK and US. Growing dissent with foreign influence culminated during the Iranian Revolution which led to establishment of an Islamic republic on 1 April 1979.^[28][29]

Iran is a founding member of the UN, NAM, OIC and OPEC. The political system of Iran, based on the 1979 constitution, comprises several intricately connected governing bodies. The highest state authority is the Supreme Leader. Shia Islam is the official religion and Persian is the official language.^[30]

Etymology[link]

The name of Iran (ایران) is the Modern Persian derivative from the Proto-Iranian term Aryānā,, meaning "Land of the Aryans", first attested in Zoroastrianism's Avesta tradition.^{[31][32][33][34]} The term Ērān is found to refer to Iran in a 3rd century Sassanid inscription, and the Parthian inscription that accompanies it uses the Parthian term "aryān" in reference to Iranians.^[35] However historically Iran has been referred to as Persia or similar (La Perse, Persien, Perzië, etc.) by the Western world, mainly due to the writings of Greek historians who called Iran Persis (Περσίς), meaning land of the Persians. In 1935 Rezā Shāh requested that the international community should refer to the country as Iran. Opposition to the name change led to the reversal of the decision, and in 1959 both names were to be used interchangeably.^[36] Since the Iranian Revolution in 1979 the official name of the country has been the "Islamic Republic of Iran."

History[link]

Pre-Historic era[link]

The earliest archaeological artifacts in Iran were found in the Kashafrud and Ganj Par sites that date back to the Lower Paleolithic era. Mousterian Stone tools made by Neanderthal man have also been found.^[37] There are more cultural remains of Neanderthal man dating back to the Middle Paleolithic period, which have been found mainly in the Zagros region and less frequently in central Iran at sites such as Shanidar, Kobeh, Kunji, Bisetun, Tamtama, Warwasi, Palegawra, and Yafteh Cave.^[38] Discovery of human skeletons in the Huto cave and the adjacent Kamarband cave near the town of Behshahr in the Mazandaran Province, and Amol and Babol old cities north of Iran, south of the Caspian Sea, suggest human habitation of the area as early as 75,000 years ago.^[39] However, recent studies in the valleys of Shuresh, around the earlier mentioned caves, led to the discovery of 400,000 year old stone tools.^[40] Evidence for Upper Paleolithic and Epipaleolithic periods are known mainly from the Zagros region in the caves of Kermanshah and Khorramabad.

Early agricultural communities such as Chogha Bonut in 8000 BC,^[41][42] Susa (now a city still existing since 7000 BC)^[43][44] and Chogha Mish dating back to 6800 BC.^[45][46] started to form in the western Iran. Dozens of pre-historic sites across the Iranian plateau point to the existence of ancient cultures and urban settlements in the 4th millennium BC,^[46][47][48] centuries before the earliest civilizations arose in nearby Mesopotamia.^[49]

Early history (3200 BC – 625 BC)[link]

19th century reconstruction of a map of the world by Eratosthenes, c.200 BC. The name Ariana (Aryânâ) was used to describe the region where the Iranian plateau is found.

Elam was part of the early urbanization during the Chalcolithic. The emergence of written records from around 3000 BC also parallels Mesopotamian history. In the Old Elamite period (Middle Bronze Age), from around 2800 BC, Elam consisted of kingdoms on the Iranian plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. The Elamite kingdom continued its existence until the emergence of the Median and Achaemenid Empires.

Proto-Iranians first emerged following the separation of Indo-Iranians, and are traced to the Andronovo culture.^[50] 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 the 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.

Pre-Islamic statehood (625 BC – 651 AD)[link]

The Cyrus Cylinder a document issued by Cyrus the Great and regarded by some as a charter of human rights

The Medes are credited with the unification^[3] of Iran as a nation and empire (625^[3]–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 II continued his father's work of conquest, making significant gains in Egypt.

Following a power struggle after Cambyses' death, Darius the Great was declared king (ruled 522–486 BC). Under Cyrus and Darius, the Persian Empire eventually became the largest and most powerful empire in human history up until that point.^[51] 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 continued through the first half of the 5th century BC. During the Greco-Persian Wars Persia made some major advances 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.^{[citation needed]} 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 Southeast 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.^[52]

In 334 BC, Alexander the Great 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, and the subsequent formation of the Seleucid Empire.

A bust from the National Museum of Iran of Musa of Parthia

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. This was 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".^[53] 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 was defeated by General Surena in the Battle of Carrhae in 53 BC.^[54]

Persian and Median soldiers at Persepolis

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 Iranians", (i.e. of Iranians), with their capital at Ctesiphon.^[55] 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.^[56] During their reign, Sassanid battles with the Roman Empire caused such pessimism in Rome that the historian Cassius Dio wrote:

Geographical extent of Iranian influence in the 1st century BC. The Parthian Empire (mostly Western Iranian) is shown in red, other areas, dominated by Scythia (mostly Eastern Iranian), in orange.

In 632 raiders from the Arab peninsula began attacking the Sassanid Empire. Iran was defeated in the Battle of al-Qādisiyyah, paving way for the Muslim conquest of Persia.

During the Parthian and later Sassanid eras, 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.^[58]

The Parthians were innovators of many architecture designs such as that of Ctesiphon, which later influenced European Romanesque architecture.^[59][60] 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.

Middle Ages (652–1501)[link]

Map of Iranian Dynasties c. 1000

After the Muslim conquest of Persia, most of the urban lands of the Sassanid Empire, with the exception of Caspian provinces and Transoxiana, came under Islamic rule.^[61] Many provinces in Iran defended themselves against the Arab invaders, although none in the end were able to repulse the invaders. However, when the Arabs had subdued the country, many of the cities rose in rebellion, killing Arab governors, although reinforcement by Arab armies succeeded in putting down the rebellions.

However, the Iranians' conversion to Islam was a complex process and is generally considered to have been gradual; the notion of force has largely been discredited,^[62] although occasional acts of violence did take place, with Zoroastrian scriptures being burned and Zoroastrian priests being executed.^[61][63]

By the 9th century, Islam became a dominant religion in Persia and the conversion of Iranians to Islam brought profound changes to their life and culture.^[61] However, in some regions, such as the Fars province, Zoroastrianism remained strong up to the 9th century, although Sufis such as Abu Eshaq Kazeruni, the founder of Kazeruni Sufi order, brought mass conversion of Zoroastrians to Islam in the 10th century.^[61]

During the Abbasid caliphate decline, independent^[64][65] and semi-independent native Iranian dynasties arose in different parts of Persia including the Tahirids, Saffarids, Samanids, Afrighids, Ghurids, Sallarids, 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.^[66] In reaction to these, Abu Moslem, an Iranian^[67][68] general, expelled the Umayyads from Damascus and helped the Abbasid caliphs to conquer Baghdad. The Abbasid caliphs frequently chose their Iranians as their "wazirs" (viziers), 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.^[69]

Attempts at Arabization thus never succeeded in Iran, and movements such as the Shu'ubiyya became catalysts for Iranians to regain their independence in their relations with the Arab invaders.^[70] Other notable major revolts, some by Iranian Muslims and others by practitioners of old Iranian religions against Arab rule were led 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 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,^[71] turning the streets of Persian cities such as Nishapur 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".^[72]

Khwarezmid Empire around 1200

According to Steven R. Ward, "Overall, the Mongol violence and depredations killed up to three-fourths of the population of the Iranian plateau, possibly 10 to 15 million people. Some historians have estimated that Iran's population did not again reach its pre-Mongol levels until the mid-20th century."^[73] In a letter to King Louis IX of France, Holaku, one of the Genghis Khan's grandsons, took sole responsibility for 200,000 deaths in his raids of Iran and the Caliphate.^[74] He was followed by yet another conqueror, Tamerlane, who established his capital in Samarkand.^[75] The waves of devastation prevented many cities such as Nishapur from reaching their pre-invasion population levels until the 20th century, eight centuries later.^[76]

In 1387, Tamerlane avenged a revolt in Isfahan by massacring 70,000 people.^[77] 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.^[78] The mid-14th-century Black Death killed about 30% of the country's population.^[79]

Iran was gradually Islamized after the collapse of the Sassanid Empire; however, it was not Arabized. Iranian culture re-emerged with a separate and distinctive character and made an immense contribution to the Islamic civilization.^[80][81] When Islam came through Iran, what developed was an Iranian Islam or Persian Islam rather than the original Arab Islam, and this new Islam is sometimes referred to by scholars as Islam-i Ajam (Persian Islam).^[80][82]

It was this Persian Islam and Sufism which was brought to new areas and new peoples such as the Turks of Central Asia, the Ottoman Empire, and the Indian subcontinent.^[80] Among the major Iranian Muslims who cultivated Sufism and helped the spread of Islam through Sufism, one can mention Habib Ajami, Hallaj, Hasan Basri, Junayd Baghdadi, Bayazid Bastami, Maruf Karkhi, Abdul-Qadir Gilani, Moinuddin Chishti, Jalaluddin Rumi, Najmuddin Kubra, and Baha-ud-Din Naqshband Bukhari. Note should also be made of Abu Hanifa, the founder of the Hanafi school of thought which is followed by most Muslims today.

Arabic writer Ibn Khaldun has remarked that the sedentary culture which was necessary for the development of civilization was rooted in the Persian empire.^[83]

One of the main developments after the advent of Islam in Iran was the rise of the New Persian language as an important Indo-European language. The New Persian language was an evolution of Middle Persian, which in turn was derived from Old Persian. New Persian absorbed a considerable amount of Arabic vocabulary^[84][85] during this era, although the Arabic vocabulary that was Persianized^[86] often took a different meaning than the Arabic origin. In terms of contribution to the Arabic language, Iranians like Sibawayhi^[87] pioneered writing books of grammar of the Arabic language.

Culturally, Iranians preserved their language, while they used Arabic for scientific and philosophical discourses;^[88] this enabled them to reach a worldwide audience for the first time.^[88] After the 10th century, Persian, written in the modified Perso-Arabic script alongside Arabic, was used for scientific, philosophical, historical, mathematical, musical, and medical works, as important Iranian writers such as Nasir al-Din al-Tusi, Avicenna, Qotb al-Din Shirazi, Gurgani, Nasir Khusraw, Biruni, Abd al-Qadir Maraghi made contributions to Persian scientific writing.

During this era, Iranians continued on a much larger scale the cultural and scientific enterprises set up by the Sassanids.^[89] The blossoming Persian literature, philosophy, medicine, and art became major elements in the forming Muslim civilization. The Islamic Golden Age, which is characterized by developments in science, owed to a large extent its importance to vital contributions made by Iranians.^[90] The Islamic Golden Age reached its peak in the 10th and 11th centuries, during which Persia was the main theatre of scientific activity.^[89] The Persian influence of this period relied heavily upon the achievements of the Sassanids, and the weight of this influence has led the Muslim world to accept Islamic civilization as the Perso-Islamic civilization.^[91]

Even in the development of Arabic scientific prose itself, which differs in style from that of the Quran, Persian scholars such as Abdullah Ibn al-Muqaffaʿ had a major role. Indeed, the class of clerks and civil administrators that was responsible for the cultivation of the sciences in the early Islamic centuries consisted mostly of Persians.^[92] The contributions of Iranians to the Arabic language are however not limited to scientific prose but are also found in Arabic poetry. The contributions by Iranians are characterised as "the lively and graceful fancy, elegance of diction, depth and tenderness of feeling, and a rich store of ideas".^[93]

Iranian philosophy after the Islamic conquest is characterized by different interactions with Old Iranian philosophy, with Ancient Greek philosophy, and with the development of Islamic philosophy. Illuminationism and transcendent theosophy are regarded as two of the main philosophical traditions of this era in Persia. These movements continued well into the 11th century, during which the Nizamiyya University was founded, and hundreds of Iranian scholars and scientists contributed greatly to technology, science, and medicine, later influencing the rise of European sciences during the Renaissance.^[94]

Early modern era (1501–1925)[link]

Shah Ismail I, the founder of the Safavid dynasty (1501–1736)

Iran's first encompassing Shia 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.^[27] 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 Pashtun rebels headed by the Hotakis of Kandahar defeated Sultan Husayn and ended the Safavid dynasty, but in 1735, Nader Shah successfully drove out the Pashtuns from Isfahan and established the Afsharid Dynasty.

Sattar Khan was a key figure in the Persian Constitutional Revolution

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. The Great Persian Famine of 1870–1871 is believed to have caused the death of 2 million persons.^[95]

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 and constitutionalization efforts which eventually resulted in the establishment of the nation's first parliament in 1906. This was followed by the Jangal movement of Gilan which lead to the short-lived Gilan Republic.

Pahlavi dynasty (1925–1979)[link]

In 1925, Reza Khan overthrew the weakening Qajar dynasty and became Shah. Rezā Shāh initiated industrialization, railroad construction, and the establishment of a national education system. Rezā Shāh 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 favor of his son, Mohammad Reza Pahlavi.

In 1951, after the assassination of prime minister Ali Razmara, Dr. Mohammad Mosaddegh was elected prime minister by a parliamentary vote which was then ratified by the Shah. As prime minister, Mosaddegh became enormously popular in Iran after he nationalized Iran's petroleum industry and oil reserves. In response, the British government, headed by Winston Churchill, embargoed Iranian oil and successfully enlisted the United States to join in a plot to depose the democratically elected government of Mosaddegh. In 1953 US President Dwight D. Eisenhower authorized Operation Ajax. The operation was successful, and Mosaddegh was arrested on 19 August 1953. The coup was the first time the US had openly overthrown an elected, civilian government.^[96]

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.

Islamic Republic (1979–present)[link]

The Iranian Revolution, also known as the Islamic Revolution,^[97][98][99] began in January 1978 with the first major demonstrations against the Shah.^[100] After strikes and demonstrations paralyzed the country and its economy, the Shah fled the country in January 1979 and Ayatollah Ruhollah 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.^[28][29] In parallel nation wide uprisings against the new regime erupted in Kordestan, Khuzestan, Balochistan and other areas, though were eventually subdued, with some lasting until late 1980.

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,^[101] as it had not been precipitated by a military defeat, a financial crisis, or a peasant rebellion.^[102] 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, and the revolution ultimately resulted in an Islamic Republic under Ayatollah Ruhollah Khomeini.^[103]

Ayatollah Khomeini, founder of the Islamic Republic of Iran

Iran – United States relations deteriorated rapidly during the revolution. On 4 November 1979, a group of Iranian students seized US embassy personnel, labeling the embassy a "den of spies".^[104] They accused its personnel of being CIA agents plotting to overthrow the revolutionary government, as the CIA had done to Mosaddegh 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.^[105]

While most of the female and African American hostages were released within the first months,^[105] the remaining 52 hostages were held for 444 days. Subsequent attempts by the Jimmy Carter administration to negotiate or rescue were unsuccessful. In January 1981 the hostages were set free according to the Algiers Accords.

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, allying with the Iraqi Kurds, who rose up in rebellion against Saddam. Khomeini sought to export his Islamic revolution westward into Iraq, especially on the majority Shia 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.^{[107][verification needed]} 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.^{[108][109][110][verification needed]}

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 European Union 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.^[111]

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.^[112]

A significant challenge to Ahmadinejad's political power, and the foundations of the Islamic Republic itself occurred during the 2009 Iranian presidential election that was held on 12 June 2009,^[113] the tenth presidential election to be held in the country.^[114] The Interior Ministry, announced incumbent president Mahmoud Ahmadinejad had won the election with 62.63% receiving 24.5 million vote, while Mir-Hossein Mousavi had come in second place with 13.2 million votes 33.75%.^[115][116] There were large irregularities in the results and people were surprised by them, which resulted in protests gathering millions of Iranians in every Iranian city and around the world.^[117][118]

Geography[link]

Topography of Iran

Iran is the eighteenth largest country in the world,^[119] with an area of 1,648,000 km² (636,000 sq mi).^[120]

4000 years old Cypress of Abarqu is the oldest tree in Iran and the second oldest tree in the world.

Its area roughly equals that of the United Kingdom, France, Spain, and Germany combined, or somewhat more than the US state of Alaska.^[121] Iran lies between latitudes 24° and 40° N, and longitudes 44° and 64° E. Its borders are with Azerbaijan (611 km/380 mi (with Azerbaijan-Naxcivan exclave (179 km/111 mi ))^[122] and Armenia (35 km/22 mi) to the north-west; the Caspian Sea to the north; Turkmenistan (992 km/616 mi) to the north-east; Pakistan (909 km/565 mi) and Afghanistan (936 km/582 mi) to the east; Turkey (499 km/310 mi) and Iraq (1,458 km/906 mi) to the west; and finally the waters of the Persian Gulf and the Gulf of Oman to the south.

Mount Damavand, Iran's highest point, is located in Amol County, Mazanderan.

Iran consists of the Iranian Plateau with the exception of the coasts of the Caspian Sea and Khuzestan Province. It is one of the world's most mountainous countries, its landscape dominated by rugged mountain ranges that separate various basins or plateaux from one another. The populous western part is the most mountainous, with ranges such as the Caucasus, Zagros and Alborz Mountains; the last contains Iran's highest point, Mount Damavand, Babol at 5,610 m (18,406 ft), which is also the highest mountain on the Eurasian landmass west of the Hindu Kush.^[123]

The northern part of Iran is covered by dense rain forests called Shomal or the Jungles of Iran. The eastern part consists mostly of desert basins such as the Dasht-e Kavir, Iran's largest desert, in the north-central portion of the country, and the Dasht-e Lut, in the east, as well as some salt lakes. This is because the mountain ranges are too high for rain clouds to reach these regions. The only large plains are found along the coast of the Caspian Sea and at the northern end of the Persian Gulf, where Iran borders the mouth of the Shatt al-Arab (or the Arvand Rūd) river. Smaller, discontinuous plains are found along the remaining coast of the Persian Gulf, the Strait of Hormuz and the Gulf of Oman.

Climate[link]

Simplified Climatic Map of Iran

  Caspian Mild

  Mountains

  Arid and Semi-Arid

Iran's climate ranges from arid or semiarid, to subtropical along the Caspian coast and the northern forests. On the northern edge of the country (the Caspian coastal plain) temperatures rarely fall below freezing and the area remains humid for the rest of the year. Summer temperatures rarely exceed 29 °C (84.2 °F).^[124][125] Annual precipitation is 680 mm (26.8 in) in the eastern part of the plain and more than 1,700 mm (66.9 in) in the western part.

To the west, settlements in the Zagros basin experience lower temperatures, severe winters with below zero average daily temperatures and heavy snowfall. The eastern and central basins are arid, with less than 200 mm (7.9 in) of rain, and have occasional deserts.^[125] Average summer temperatures exceed 38 °C (100.4 °F). The coastal plains of the Persian Gulf and Gulf of Oman in southern Iran have mild winters, and very humid and hot summers. The annual precipitation ranges from 135 to 355 mm (5.3 to 14.0 in).^[125]

Fauna[link]

Persian Leopard

Iran's wildlife is composed of several animal species including bears, gazelles, wild pigs, wolves, jackals, panthers, Eurasian Lynx, and foxes. Domestic animals include, sheep, goats, cattle, horses, water buffalo, donkeys, and camels. The pheasant, partridge, stork, eagles and falcon are also native to Iran.

One of the most famous members of Iranian wildlife is the critically endangered Asiatic cheetah, also known as the Iranian Cheetah, whose numbers were greatly reduced after the Iranian Revolution. Today there are ongoing efforts to increase its population and introduce it back in India. Iran had lost all its Asiatic Lion and the now extinct Caspian Tigers by the earlier part of the 20th century.^[126]

Iran is divided into thirty one provinces (ostān), each governed by an appointed governor (استاندار, ostāndār). The provinces are divided into counties (shahrestān), and subdivided into districts (bakhsh) and sub-districts (dehestān).

Iran has one of the highest urban growth rates in the world. From 1950 to 2002, the urban proportion of the population increased from 27% to 60%.^[127] The United Nations predicts that by 2030, 80% of the population will be urban.^[128] Most internal migrants have settled near the cities of Tehran, Isfahan, Ahvaz, and Qom. The listed populations are from the 2006/07 (1385 AP) census.^[129] Tehran, with a population of 7,705,036, is the largest city in Iran and is the capital. Tehran, like many big cities, suffers from severe air pollution. It is the hub of the country's communication and transport network.

Mashhad, with a population of 2,410,800, is the second largest Iranian city and the centre of the Razavi Khorasan Province. Mashhad is one of the holiest Shia cities in the world as it is the site of the Imam Reza shrine. It is the centre of tourism in Iran, and between 15 and 20 million pilgrims go to the Imam Reza's shrine every year.^[130][131]

Another major Iranian city is Isfahan (population 1,583,609), which is the capital of Isfahan Province. The Naqsh-e Jahan Square in Isfahan has been designated by UNESCO as a World Heritage Site. The city contains a wide variety of Islamic architectural sites ranging from the 11th to the 19th century. The growth of the suburban area around the city has turned Isfahan into Iran's second most populous metropolitan area (3,430,353).^[132]

The fourth major city of Iran is Tabriz (population 1,378,935), the capital of the East Azerbaijan Province. It is also the second industrial city of Iran after Tehran. Tabriz had been the second largest city in Iran until the late 1960s and one of its former capitals and residence of the crown prince under the Qajar dynasty. The city has proven extremely influential in the country’s recent history.

The fifth major city is Karaj (population 1,377,450), located in Alborz Province and situated 20 km west of Tehran, at the foot of the Alborz mountains; however, the city is increasingly becoming an extension of metropolitan Tehran.

The sixth major Iranian city is Shiraz (population 1,214,808); it is the capital of Fars Province. The Elamite civilization to the west greatly influenced the area, which soon came to be known as Persis. The ancient Persians were present in the region from about the 9th century BC, and became rulers of a large empire under the Achaemenid dynasty in the 6th century BC. The ruins of Persepolis and Pasargadae, two of the four capitals of the Achaemenid Empire, are located in or near Shiraz. Persepolis was the ceremonial capital of the Achaemenid Empire and is situated 70 km northeast of modern Shiraz. UNESCO declared the citadel of Persepolis a World Heritage Site in 1979.

Culture[link]

City Theater of Tehran, the largest Theater auditorium in the Middle East

The culture of Iran is a mix of ancient pre-Islamic culture and Islamic culture. Iranian culture has long been a predominant culture of the Middle East and Central Asia, with Persian considered the language of intellectuals during much of the 2nd millennium, and the language of religion and the populace before that.

The Sassanid era was an important and influential historical period in Iran as Iranian culture influenced China, India and Roman civilization considerably,^[135] and so influenced as far as Western Europe and Africa.^[136] This influence played a prominent role in the formation of both Asiatic and European medieval art.^[137] This influence carried forward to the Islamic world. Much of what later became known as Islamic learning, such as philology, literature, jurisprudence, philosophy, medicine, architecture and the sciences were based on some of the practises taken from the Sassanid Persians to the broader Muslim world.^{[138][139][140]}

After Islamization of Iran Islamic rituals have penetrated in the Iranian culture. The most noticeable one of them is commemoration of Husayn ibn Ali. Every year in Day of Ashura most of Iranians, including Armenians and Zoroastrians participate in mourning for the martyrs of battle of Karbala. Daily life in modern Iran is closely interwoven with Shia Islam and the country's art, literature, and architecture are an ever-present reminder of its deep national tradition and of a broader literary culture.^[140][141]

The Iranian New Year (Nowruz) is an ancient tradition celebrated on 21 March to mark the beginning of spring in Iran. It is also celebrated in Afghanistan, Republic of Azerbaijan, Uzbekistan, Turkmenistan, Tajikistan, Kazakhstan and previously also in Georgia and Armenia. It is also celebrated by the Iraqi and Anatolian Kurds.^[142] Nowruz was registered on the list of Masterpieces of the Oral and Intangible Heritage of Humanity^[143] and described as the Persian New Year^{[144][145][146][147]} by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2009.

Language and literature[link]

Geographic distribution of the Modern Iranian languages: Persian (green), Pashto (purple) and Kurdish (turquoise), Lurish (red), Baloch (Yellow), as well as smaller communities of other Iranian languages

Article 15 of the Iranian constitution states that the "Official language (of Iran)... is Persian...[and]... the use of regional and tribal languages in the press and mass media, as well as for teaching of their literature in schools, is allowed in addition to Persian." Persian serves as a lingua franca in Iran and most publications and broadcastings are in this language.

Next to Persian, there are many publications and broadcastings in other relatively popular languages of Iran such as Azeri, Kurdish and even in less popular ones such as Arabic and Armenian. Many languages originated in Iran, but Persian is the most used language. Persian belongs to the Iranian branch of the family of Indo-European languages. The oldest records in Old Persian date to the Achaemenid Empire,^[148] and examples of Old Persian have been found in present-day Iran, Iraq, Turkey and Egypt.

In the late 8th century, Persian was highly Arabized and written in a modified Arabic script. This caused a movement supporting the revival of Persian. An important event of this revival was the writing of the Shahname by Ferdowsi (Persian: Epic of Kings), Iran's national epic, which is said to have been written entirely in native Persian. This gave rise to a strong reassertion of Iranian national identity, and is in part credited for the continued existence of Persian as a separate language.

Persian beside Arabic has been a medium for literary and scientific contributions to the Islamic world especially in Anatolia, central Asia and Indian subcontinent. Poetry is a very important part of Persian culture. Poetry is used in many Persian classical works, whether from literature, science, or metaphysics. Persian literature has been considered by such thinkers as Goethe as one of the four main bodies of world literature.^[149]

The Persian language has produced a number of famous poets; however, only a few poets as Rumi and Omar Khayyám have surfaced among western popular readership, even though the likes of Hafiz, Saadi, Nizami^[150] Attar, Sanai, Nasir Khusraw, Jami, Taleb Amoli are considered by many Iranians to be just as influential. The books of famous poets have been translated into western languages since 1634. An example of Persian poetic influence is the poem below which is widely popular:

Hafezi'eh, tomb of Hafiz in Shiraz

Philosophy[link]

While there are ancient relations between the Indian Vedas and the Iranian Avesta, the two main families of the ancient Indo-Iranian philosophical traditions were characterized by fundamental differences in their implications for the human being's position in society and their view on the role of man in the universe.^[151][152]

Iranian philosophy after the acceptance of Islam in Persia, is characterized by different interactions with the Ancient Iranian Philosophy, the Ancient Greek philosophy and with the development of Islamic philosophy. Illuminationism and transcendent theosophy are regarded as two of the main philosophical traditions of that era in Persia. Among important contributors to philosophy in Iran are Zoroaster, Jamasp, Mardan-Farrux Ohrmazddadan, Adurfarnbag Farroxzadan, Adurbad Emedan, Iranshahri, Farabi, Avicenna, Ali ibn Sahl Rabban al-Tabari, Suhrawardi, Nasir Khusraw, Biruni, Muhammad ibn Zakariya al-Razi, Abu Yaqub al-Sijistani, Nasir al-Din Tusi, Qutb al-Din Shirazi, Mir Damad, Mulla Sadra, Mir Fendereski and Hadi Sabzevari.

Music[link]

The musical culture of Persia, while distinct, is closely related to other musical systems of the Middle East and Central Asia. It has also affinities to the music cultures of the Indian subcontinent, to a certain degree even to those of Africa, and, in the period after 1800 particularly, to that of Europe. Its history can be traced to some extent through these relationships. Like that of most of the world’s cultures, the music of Persia has depended on oral/aural transmission and learning.^[153]

Cinema[link]

Iranian cinema has thrived in modern Iran, and many Iranian directors have garnered worldwide recognition for their work. Iranian movies have won over three hundred awards in the past twenty-five years including Oscars. One of the best-known directors is Abbas Kiarostami. The media of Iran is a mixture of private and state-owned, but books and movies must be approved by the Ministry of Culture and Islamic Guidance before being released to the public. The Internet has become enormously popular among the Iranian youth. Iran is now the world's fourth largest country of bloggers.^[154]

Art and architecture[link]

Iran is home to one of the richest artistic traditions in world history and encompasses many disciplines, including architecture, painting, weaving, pottery, calligraphy, metalworking and stonemasonry. Carpet-weaving is one of the most distinguished manifestations of Persian culture and art, and dates back to ancient Persia. Persians were among the first to use mathematics, geometry, and astronomy in architecture and also have extraordinary skills in making massive domes which can be seen frequently in the structure of bazaars and mosques. The main building types of classical Iranian architecture are the mosque and the palace. Besides being home to a large number of art houses and galleries, Iran also holds one of the largest and most valuable jewel collections in the world.

Iran ranks seventh among countries in the world with the most archeological architectural ruins and attractions from antiquity as recognized by UNESCO.^[155] Fifteen of UNESCO's World Heritage Sites are creations of Iranian architecture.

Cuisine[link]

The cuisine of Iran is diverse, with each province featuring dishes, as well as culinary traditions and styles, distinct to their regions. The main Persian cuisines are combinations of rice with meat, chicken or fish and some onion, vegetables, nuts, and herbs. Herbs are frequently used along with fruits such as plums, pomegranates, quince, prunes, apricots, and raisins. Iranians also usually eat plain yogurt (Persian: ماست, māst‎) with lunch and dinner; it is a staple of the diet in Iran. To achieve a balanced taste, characteristic flavourings such as saffron, dried limes, cinnamon, and parsley are mixed delicately and used in some special dishes. Onions and garlic are normally used in the preparation of the accompanying course, but are also served separately during meals, either in raw or pickled form. Iran is also famous for its caviar.^[156] Iranian food is not piquant.

Sports[link]

Azadi Football Stadium

With two thirds of Iran's population under the age of 25, many sports are practised in Iran, both traditional and modern. Iran is the birthplace of polo,^[157] and Varzesh-e Pahlavani. Freestyle wrestling has been traditionally regarded as Iran's national sport, however today, the most popular sport in Iran is football (soccer), with the national team having reached the World Cup Final Tournament three times, and having won the Asian Cup on three occasions. Basketball is also very popular in Iran where the national team won two of the last three Asian Championships.^[158] In 1974, Iran became the first country in the Middle East to host the Asian Games. Iran is home to several unique skiing resorts,^[159] with the Tochal resort being the world's fifth-highest ski resort (3,730 m/12,238 ft at its highest station), and located only fifteen minutes away from Tehran. Being a mountainous country, Iran is a venue for hiking, rock climbing,^[160] and mountain climbing.^{[161][162][163]}

Government and politics[link]

The political system of the Islamic Republic is based on the 1979 Constitution. Accordingly, it is the duty of the Islamic government to furnish all citizens with equal and appropriate opportunities, to provide them with work, and to satisfy their essential needs, so that the course of their progress may be assured.^[164]

The system comprises several intricately connected governing bodies. The Leader of the Revolution (commonly called "Supreme Leader" in the US and the UK) is responsible for delineation and supervision of the general policies of the Islamic Republic of Iran.^[165] The Supreme Leader is Commander-in-Chief of the armed forces, controls the military intelligence and security operations; and has sole power to declare war or peace.^[165]

The heads of the judiciary, state radio and television networks, the commanders of the police and military forces and six of the twelve members of the Guardian Council are appointed by the Supreme Leader.^[165] The Assembly of Experts elects and dismisses the Supreme Leader on the basis of qualifications and popular esteem.^[166] The Assembly of Experts is responsible for supervising the Supreme Leader in the performance of legal duties.

After the Supreme Leader, the Constitution defines the President of Iran as the highest state authority.^[165][167] The President is elected by universal suffrage for a term of four years and can only be re-elected for one term.^{[167][dubious – discuss]} Presidential candidates must be approved by the Guardian Council prior to running in order to ensure their allegiance to the ideals of the Islamic revolution.^[168]

The President is responsible for the implementation of the Constitution and for the exercise of executive powers, except for matters directly related to the Supreme Leader, who has the final say in all matters.^[165] The President appoints and supervises the Council of Ministers, coordinates government decisions, and selects government policies to be placed before the legislature.^[169] Eight Vice-Presidents serve under the President, as well as a cabinet of twenty two ministers, who must all be approved by the legislature.^[170] Unlike many other states, the executive branch in Iran does not control the armed forces. Although the President appoints the Ministers of Intelligence and Defense, it is customary for the President to obtain explicit approval from the Supreme Leader for these two ministers before presenting them to the legislature for a vote of confidence. Iran's current president, Mahmoud Ahmadinejad, was first elected in a run-off poll in the 2005 presidential elections and re-elected in the 2009 presidential elections.

Iran's complex and unusual political system combines elements of a modern Islamic theocracy with democracy.

As of 2012, the legislature of Iran (known in English as the Islamic Consultative Assembly) is a unicameral body.^[171] Before the Iranian Revolution, the legislature was bicameral, but the upper house was removed under the new constitution. The Majlis of Iran comprises 290 members elected for four-year terms.^[171] The Majlis drafts legislation, ratifies international treaties, and approves the national budget. All Majlis candidates and all legislation from the assembly must be approved by the Guardian Council.^[172]

The Guardian Council comprises twelve jurists including six appointed by the Supreme Leader. The others are elected by the Parliament from among the jurists nominated by the Head of the Judiciary.^[173][174] The Council interprets the constitution and may veto Parliament. If a law is deemed incompatible with the constitution or Sharia (Islamic law), it is referred back to Parliament for revision.^[167] In a controversial exercise of its authority, the Council has drawn upon a narrow interpretation of Iran's constitution to veto parliamentary candidates. The Expediency Council has the authority to mediate disputes between Parliament and the Guardian Council, and serves as an advisory body to the Supreme Leader, making it one of the most powerful governing bodies in the country.^[175]

The Supreme Leader appoints the head of Iran's Judiciary, who in turn appoints the head of the Supreme Court and the chief public prosecutor.^[176] There are several types of courts including public courts that deal with civil and criminal cases, and "revolutionary courts" which deal with certain categories of offenses, including crimes against national security. The decisions of the revolutionary courts are final and cannot be appealed.^[176] The Special Clerical Court handles crimes allegedly committed by clerics, although it has also taken on cases involving lay people. The Special Clerical Court functions independently of the regular judicial framework and is accountable only to the Supreme Leader. The Court's rulings are final and cannot be appealed.^[176]

The Assembly of Experts, which meets for one week annually, comprises 86 "virtuous and learned" clerics elected by adult suffrage for eight-year terms. As with the presidential and parliamentary elections, the Guardian Council determines candidates' eligibility.^[176] The Assembly elects the Supreme Leader and has the constitutional authority to remove the Supreme Leader from power at any time.^[176] It has not challenged any of the Supreme Leader's decisions.^[176]

Local City Councils are elected by public vote to four-year terms in all cities and villages of Iran. According to article seven of Iran's Constitution, these local councils together with the Parliament are "decision-making and administrative organs of the State". This section of the constitution was not implemented until 1999 when the first local council elections were held across the country. Councils have many different responsibilities including electing mayors, supervising the activities of municipalities; studying, planning, co-ordinating and implementing of social, cultural, educational, health, economic, and welfare requirements of their constituencies.

Foreign relations and military[link]

Iranian soldiers

Iran's foreign relations are based on two strategic principles: eliminating outside influences in the region and pursuing extensive diplomatic contacts with developing and non-aligned countries. Iran maintains diplomatic relations with almost every member of the United Nations, except for Israel, which Iran does not recognize, and the United States since the Iranian Revolution.^[177] Since 2005, Iran's nuclear program has become the subject of contention with the Western world due to suspicions that Iran could divert the civilian nuclear technology to a weapons program. This has led the UN Security Council to impose sanctions against Iran on select companies linked to this program, thus furthering its economic isolation on the international scene. The US Director of National Intelligence said in February 2009 that Iran would not realistically be able to a get a nuclear weapon until 2013, if it chose to develop one.^[178]

The Islamic Republic of Iran has two types of armed forces: the regular forces Islamic Republic of Iran Army, Islamic Republic of Iran Air Force, Islamic Republic of Iran Navy and the Islamic Revolutionary Guards Corps (IRGC), totaling about 545,000 active troops. Iran also has around 350,000 Reserve Force totaling around 900,000 trained troops.^[179] Iran has a paramilitary, volunteer militia force within the IRGC, called the Basij, which includes about 90,000 full-time, active-duty uniformed members. Up to 11 million men and women are members of the Basij who could potentially be called up for service; GlobalSecurity.org estimates Iran could mobilize "up to one million men". This would be among the largest troop mobilizations in the world.^[180] In 2007, Iran's military spending represented 2.6% of the GDP or $102 per capita, the lowest figure of the Persian Gulf nations.^[181] Iran's military doctrine is based on deterrence.^[182]

Since the Iranian Revolution, to overcome foreign embargo, Iran has developed its own military industry, produced its own tanks, armored personnel carriers, guided missiles, submarines, military vessels, guided missile destroyer, radar systems, helicopters and fighter planes.^{[183][184][185]} In recent years, official announcements have highlighted the development of weapons such as the Hoot, Kowsar, Zelzal, Fateh-110, Shahab-3 and Sajjil missiles, and a variety of unmanned aerial vehicles (UAVs).^[186] The Fajr-3 (MIRV) is currently Iran's most advanced ballistic missile, it is a liquid fuel missile with an undisclosed range which was developed and produced domestically.

Economy[link]

There is an estimated population of 1.2 million weavers in Iran producing carpets for domestic markets and international export.^[187]

The economy of Iran is the twenty-fifth largest in the world by GDP (nominal) and the eighteenth largest economy in the world by purchasing power parity (PPP). Iran's economy is a mixture of central planning, state ownership of oil and other large enterprises, village agriculture, and small-scale private trading and service ventures.^[188] Its economic infrastructure has been improving steadily over the past two decades but continues to be affected by inflation and unemployment.^[189] In the early 21st century the service sector contributed the largest percentage of the GDP, followed by industry (mining and manufacturing) and agriculture. In 2006, about 45% of the government's budget came from oil and natural gas revenues, and 31% came from taxes and fees.^[190]

Government spending contributed to an average annual inflation rate of 14% in the period 2000–2004. As at 2007, Iran had earned $70 billion in foreign exchange reserves mostly (80%) from crude oil exports.^[191] In 2009 GDP was $336 billion ($876 billion at PPP), or $12,900 at PPP per capita.^[120] In 2008, Iran's official annual growth rate was 6%.^[192] Because of these figures and the country’s diversified but small industrial base, the United Nations classifies Iran's economy as semi-developed (1998).^{[citation needed]}

Iran's automobile production crossed the 1 million mark in 2005. Iran Khodro is the largest car manufacturer in the Middle-East. It has established joint-ventures with foreign partners from 4 continents.

About 1,659,000 foreign tourists visited Iran in 2004; most came from Asian countries, including the republics of Central Asia, while a small share came from the countries of the European Union and North America. Iran currently ranks 89th in tourist income, but is rated among the "10 most touristic countries" in the world in terms of its history.^[193][194] Weak advertising, unstable regional conditions, a poor public image in some parts of the world, and absence of efficient planning schemes in the tourism sector have all hindered the growth of tourism.

The administration continues to follow the market reform plans of the previous one and indicated that it will diversify Iran's oil-reliant economy. Iran has also developed a biotechnology, nanotechnology, and pharmaceuticals industry.^[195] The strong oil market since 1996 helped ease financial pressures on Iran and allowed for Tehran's timely debt service payments.

Iranian budget deficits have been a chronic problem, mostly due to large-scale state subsidies, that include foodstuffs and especially gasoline, totaling more than $84 billion in 2008 for the energy sector alone.^[196][197] In 2010, the economic reform plan was approved by parliament to cut subsidies gradually and replace them with targeted social assistance. The objective is to move towards free market prices in a 5-year period and increase productivity and social justice.^[198]

Over the past 15 years, the authorities have placed an emphasis on the local production of domestic-consumption oriented goods such as home appliances, cars, agricultural products, pharmaceutical, etc. Today, Iran possesses a good manufacturing industry, despite restrictions imposed by foreign countries. However, nationalized industries such as the bonyads have often been managed badly, making them ineffective and uncompetitive with years. Currently, the government is trying to privatize these industries, and, despite successes, there are still several problems to be overcome, such as the lagging corruption in the public sector and lack of competitiveness. Iran ranks 69th out of 139 in Global Competitiveness Report.^[199]

Iran has leading manufacture industry in the fields of car-manufacture and transportation, construction materials, home appliances, food and agricultural goods, armaments, pharmaceuticals, information technology, power and petrochemicals in the Middle East.^[200]

Energy[link]

Iran holds 10% of the world's proven oil reserves and 15% of its gas. It is OPEC's second largest exporter and the world's fourth oil producer.

Iran ranks second in the world in natural gas reserves and third in oil reserves.^[205][206] It is OPEC's 2nd largest oil exporter and is an energy superpower.^[207][208] In 2005, Iran spent US$4 billion on fuel imports, because of contraband and inefficient domestic use.^[209] Oil industry output averaged 4 million barrels per day (640,000 m³/d) in 2005, compared with the peak of six million barrels per day reached in 1974. In the early years of the 2000s (decade), industry infrastructure was increasingly inefficient because of technological lags. Few exploratory wells were drilled in 2005.

In 2004, a large share of natural gas reserves in Iran were untapped. Iran is the third country in the world to have developed GTL technology.^[210] The addition of new hydroelectric stations and the streamlining of conventional coal and oil-fired stations increased installed capacity to 33,000 megawatts. Of that amount, about 75% was based on natural gas, 18% on oil, and 7% on hydroelectric power. In 2004, Iran opened its first wind-powered and geothermal plants, and the first solar thermal plant is to come online in 2009.

Demographic trends and intensified industrialization have caused electric power demand to grow by 8% per year. The government’s goal of 53,000 megawatts of installed capacity by 2010 is to be reached by bringing on line new gas-fired plants and by adding hydroelectric, and nuclear power generating capacity. Iran’s first nuclear power plant at Bushehr went online in 2011.^[211][212]

Science and technology[link]

An 18th century Persian astrolabe

Ancient Iranians built Qanats and Yakhchal to provide and keep water. The first windmill appeared in Iran in the 9th century.^[213] Iranians contributed significantly to the current understanding of astronomy, natural science, medicine, mathematics, and philosophy. Khwarizmi is widely hailed as the father of algebra. Ethanol (alcohol) was first identified by Persian alchemists such as Muhammad ibn Zakarīya Rāzi. Throughout the Middle Ages, the natural philosophy and mathematics of the Ancient Greeks and Persians were furthered and preserved within Persia. The Academy of Gundishapur was a renowned centre of learning in the city of Gundeshapur during late antiquity and was the most important medical centre of the ancient world during the 6th and 7th centuries.^[214] During this period, Persia became a centre for the manufacture of scientific instruments, retaining its reputation for quality well into the 19th century.

Iran strives to revive the golden age of Persian science. The country has increased its publication output nearly tenfold from 1996 through 2004, and has been ranked first in terms of output growth rate followed by China.^[215] Despite the limitations in funds, facilities, and international collaborations, Iranian scientists remain highly productive in several experimental fields, such as pharmacology, pharmaceutical chemistry, organic chemistry, and polymer chemistry. Iranian scientists are also helping construct the Compact Muon Solenoid, a detector for CERN's Large Hadron Collider. In 2009, a SUSE Linux-based HPC system made by the Aerospace Research Institute of Iran (ARI) was launched with 32 cores and now runs 96 cores. Its performance was pegged at 192 GFLOPS.^[216] Sorena 2 Robot, which was designed by engineers at University of Tehran, was unveiled in 2010. the Institute of Electrical and Electronics Engineers (IEEE) has placed the name of Surena among the five prominent robots of the world after analyzing its performance.^[217]

In the biomedical sciences, Iran's Institute of Biochemistry and Biophysics is a UNESCO chair in biology.^[218] In late 2006, Iranian scientists successfully cloned a sheep by somatic cell nuclear transfer, at the Rouyan research centre in Tehran.^[219] According to a study by David Morrison and Ali Khademhosseini (Harvard-MIT and Cambridge), stem cell research in Iran is amongst the top 10 in the world.^[220] Iran ranks 15th in the world in nanotechnologies.^{[221][222][223]}

Omid satellite. Iran is the 9th country to put a domestically built satellite into orbit.

The Iranian nuclear program was launched in the 1950s. Iran is the 7th country in production of uranium hexafluoride^[224] and controls the entire cycle for producing nuclear fuel.^[225] Iran's current facilities includes several research reactors, a uranium mine, an almost complete commercial nuclear reactor, and uranium processing facilities that include a uranium enrichment plant.

The Iranian Space Agency launched its first reconnaissance satellite named Sina-1 in 2006, and a space rocket in 2007,^[226] which aimed at improving science and research for university students.^[227] Iran placed its domestically built satellite, Omid into orbit on the 30th anniversary of the Iranian Revolution, on 2 February 2009,^[228] through Safir rocket, becoming the ninth country in the world capable of both producing a satellite and sending it into space from a domestically made launcher.^[229]

Iranian scientists outside Iran have also made some major contributions to science. In 1960, Ali Javan co-invented the first gas laser and fuzzy set theory was introduced by Lotfi Zadeh.^[230] Iranian cardiologist, Tofy Mussivand invented and developed the first artificial cardiac pump, the precursor of the artificial heart. Furthering research and treatment of diabetes, HbA1c was discovered by Samuel Rahbar. Iranian physics is especially strong in string theory, with many papers being published in Iran.^[231] Iranian-American string theorist Cumrun Vafa proposed the Vafa-Witten theorem together with Edward Witten.

Demographics[link]

Iran ethnoreligious distribution

Iran is a diverse country consisting of people of many religions and ethnic backgrounds cemented by the Persian culture.^[232] The majority of the population speaks the Persian language, which is also the official language of the country, as well as other Iranian languages or dialects. Turkic languages and dialects, most importantly Azeri language, are spoken in different areas in Iran. Additionally, Arabic is spoken in the southwestern parts of the country. The exact ethnic breakdown of Iran is unknown as there are no official numbers, however some organizations have made estimates. The World Factbook released the estimate: Persians (61%), Azerbaijanis (16%), Kurds (10%), Lurs (6%), Arabs (2%), Balochs (2%), Turkmens and Turkic tribes (2%),^[233] Laks, Qashqai, Pashtuns, Armenians, Georgians, Persian Jews, Assyrians, Circassians, Tats, Mandaeans, Gypsies, Brahuis, Kazakhs and others (1%).^[120] However according to them Persian is spoken as first language by 53%, while Azeri and other Turkic dialects is spoken by 18%, Kurdish by 10%, Gilaki and Mazandarani by 7%, Luri by 6%, Balochi by 2%, Arabic by 2% and that some 2% have other languages as first language.^[120]

The Library of Congress estimates are as following: Persians (65%), Azerbaijanis (16%), Kurds (7%), Lurs (6%), Arabs (2%), Baluchi (2%), Turkmens (1%), Turkic tribal groups such as the Qashqai (1%), and non-Persian, non-Turkic groups such as Armenians, Assyrians, Pashtuns and Georgians (less than 1%). According to it Persian is spoken as a mother tongue by at least 65% of the population and as a second language by a large proportion of the remaining 35%.^[234]

Population of Iran

Iran's population increased dramatically during the latter half of the 20th century, reaching about 75 million by 2009.^[235] According to the 1956 census the population of Iran was about 19 million.^[236] In recent years, however, Iran's birth rate has dropped significantly. Studies project that Iran's rate of population growth will continue to slow until it stabilizes above 105 million by 2050.^[237][238] More than two-thirds of the population is under the age of 30, and the literacy rate is 82%.^[239] Women today compose more than half of the incoming classes for universities around the country and increasingly continue to play pivotal roles in society.

Iran hosts one of the largest refugee populations in the world, with more than one million refugees, mostly from Afghanistan and Iraq.^[240] Since 2006, Iranian officials have been working with the UNHCR and Afghan officials for their repatriation.^[241] According to estimates, about five million Iranian citizens have emigrated to other countries, mostly since the Iranian Revolution in 1979.^[242][243]

According to the Iranian Constitution, the government is required to provide every citizen of the country with access to social security that covers retirement, unemployment, old age, disability, accidents, calamities, health and medical treatment and care services. This is covered by public revenues and income derived from public contributions. The World Health Organization in on health systems ranked Iran's performance on health level 58th, and its overall health system performance 93rd among the world's nations in 2000.^[244]

Religion[link]

Religion in Iran is dominated by the Twelver Shia branch of Islam, which is the official state religion and to which about 90% to 95%^{[245][246][247]} of Iranians belong. About 4% to 8% of Iranians belong to the Sunni branch of Islam, mainly Kurds and Iran's Balochi Sunni. The remaining 2% are non-Muslim religious minorities, including Bahá'ís, Mandeans, Hindus, Yezidis, Yarsanis, Zoroastrians, Jews, and Christians.^[120]

The latter three minority religions are officially recognized and protected, and have reserved seats in the Majlis (Parliament). However the Bahá'í Faith, Iran's largest religious minority,^[248] is not officially recognized, and has been persecuted during its existence in Iran. Since the 1979 revolution the persecution of Bahá'ís has increased with executions, the denial of civil rights and liberties, and the denial of access to higher education and employment.^[249][250]
