I. INTRODUCTION
In the 6th century bc the territory of present-day Iran was the center of the Persian Empire, the world’s preeminent power at that time. For more than 2,000 years, the region’s inhabitants have referred to it by the name Iran, derived from the Aryan tribes who settled the area long ago. However, until 1935, when the Iranian ruler demanded that the name Iran be used, the English-speaking world knew the country as Persia, a legacy of the Greeks who named the region after its most important province, Pars (present-day Fārs). Iran was a monarchy ruled by a shah, or king, from 1501 until 1979, when a yearlong popular revolution led by the Shia clergy culminated in the overthrow of the monarchy and the establishment of an Islamic republic. See Islamic Revolution of Iran. Iran lies at the easternmost edge of the geographic and cultural region known as the Middle East. The country is bordered on the north by Armenia, Azerbaijan, the Caspian Sea, and Turkmenistan; on the east by Afghanistan and Pakistan; on the south by the Gulf of Oman, the Strait of Hormuz, and the Persian Gulf; and on the west by Iraq and Turkey. Iran’s capital and largest city is Tehrān, located in the northern part of the country. II. LAND AND RESOURCESIran is the second largest country in the Middle East, after Saudi Arabia. It extends over a total area of 1,648,000 sq km (636,300 sq mi). The country is roughly triangular in shape, with its longest side extending in a slightly outward arc for 2,500 km (1,600 mi) from the border with Turkey in the northwest to the border with Pakistan in the southeast. The third point of the triangle lies in the northeast, about halfway along Iran’s border with Turkmenistan. Iran’s greatest extent from north to south is 1,600 km (1,000 mi) and from east to west is 1,700 km (1,100 mi).

The population of Iran was estimated at 68,278,826
in 2003. This figure is more than double the 1975 population of 33,379,000.
Between 1956 and 1986 Iran's population grew at a rate of more than 3 percent
per year. The growth rate began to decline in the mid-1980s after the government
initiated a major population control program. By 2003 the growth rate had
declined to 1.1 percent per year, with a birth rate of 17 per 1,000 persons and
a death rate of 6 per 1,000. In 1998, 44 percent of the population was under age
15, 53 percent was between 15 and 64, and only 4 percent was aged 65 or older.
Overall population density in 2003 was 41 persons
per sq k
m (107 per sq mi). Northern and western Iran are more densely populated
than the arid eastern half of the country, where population density in the
extensive desert regions is only 1 percent of the national average. In 2001, 65
percent of the population lived in urban areas. About 99 percent of rural
Iranians resided in villages. Only 240,000 were nomads (people without
permanent residences who migrate seasonally), a fraction of the 2 million nomads
counted in 1966.

Tehrān, the country’s capital and largest city, serves as the main administrative, commercial, educational, financial, industrial, and publishing center. Iran's other major cities include Mashhad, a manufacturing and commercial center in the northeast and the site of the country's most important religious shrine; Eşfahān, a manufacturing center for central Iran with several architecturally significant public buildings from the 17th and 18th centuries; Tabrīz, the main industrial and commercial center of the northwest; Shīrāz, a manufacturing center in the south near the ruins of the ancient Persian capital of Persepolis; and Ahvāz, the principal commercial and manufacturing center in the southwestern oil region.
Iran’s population is made up of numerous ethnic groups. Persians migrated to the region from Central Asia beginning in the 7th century bc and established the first Persian empire in 550 bc. They are the largest ethnic group, and include such groups as the Gilaki, who live in Gilān Province, and the Mazandarani, who live in Māzandarān Province. Accounting for about 60 percent of the total population, Persians live in cities throughout the country, as well as in the villages of central and eastern Iran. Two groups closely related to the Persians both ethnically and linguistically are the Kurds and the Lurs. The Kurds, who make up about 7 percent of the population, reside primarily in the Zagros Mountains near the borders with Iraq and Turkey. The Lurs account for 2 percent of the population; they inhabit the central Zagros region. Turkic tribes began migrating into northwestern Iran in the 11th century, gradually changing the ethnic composition of the region so that by the late 20th century East Azerbaijan Province was more than 90 percent Turkish. Since the early 1900s, Azeris (a Turkic group) have been migrating to most large cities in Iran, especially Tehrān. Azeris and other Turkic peoples together account for about 25 percent of Iran’s inhabitants. The remainder of the population comprises small communities of Arabs, Armenians, Assyrians, Baluchis, Georgians, Pashtuns, and others.
Modern Persian is the official language of Iran. An ancient literary language, Persian was written in the Pahlavi script before the Arab conquest in the 7th century. A new form written in the Arabic script developed during the 9th and 10th centuries; this is the basis of the Modern Persian language used today (see Persian Language; Arabic Language: Arabic Script). As recently as 1950 there were several distinct dialects of spoken Persian, but due to the spread of public education and broadcast media, a standard spoken form, with minor regional accents, has evolved. Important languages of minority groups that have their own publications and broadcast programs include Azeri (a Turkic language of the Altaic family), Kurdish, Arabic, and Armenian.
Jafari Shia Islam has been the official religion of
Iran since the 16th century. Followers of Shia Islam disagree with Sunni Muslims
(see Sunni Islam), who form the majority of Muslims in the Middle East
and the Islamic world, over the rightful succession to the Prophet Muhammad, the
founder of Islam. Iran’s 1979 constitution assigns to the Shia clergy important
political leadership roles in the government. An estimated 93 percent of all
Iranians follow Shia Islam, and nearly all are members of the Jafari group.
Because Jafaris believe there are 12 legitimate successors, or imams, to
Muhammad, they are often called Twelvers. Most of the remaining population
belongs to other Islamic denominations, primarily Sunni Islam. In towns where
there are mixed Muslim communities, religious tensions have surfaced frequently,
especially during major religious observances. Sufism, or Islamic mysticism, is
popular among Shia and Sunni Muslims seeking spiritual interpretations of
religion. Iran also has small communities of Armenian and Assyrian Christians,
Jews, and Zoroastrians. The Baha’i faith, which originated in Iran during the
19th century, has several thousand secret followers, even though it has been a
target of official persecution since the Islamic republic came to power in 1979.
Public primary education was introduced in Iran after the country’s first constitution was drafted in 1906. Predominantly an urban system, it expanded only gradually and did not include secondary education until 1925. At the time of the 1979 Islamic revolution, only 60 percent of Iranian children of primary school age, and less than 50 percent of those of secondary school age, were enrolled in public schools; overall adult literacy was only 48 percent. Since 1979 the government has given a high priority to education, with programs focusing on adult literacy, new school construction, and expansion of public colleges and other institutes of higher education. By 2003 literacy for all Iranians aged 15 and older had reached 79.4 percent. The literacy rate was higher for males (85.6 percent) than for females (73 percent); the rate was also higher in cities than in rural areas.
Both the public education system and an expanding private school system consist of a five-year primary school cycle, a three-year middle school cycle, and a four-year high school cycle. Education is compulsory for children between the ages of 6 and 11. All villages now have at least a primary school, and 87.6 percent of primary school-aged children were enrolled in school in 1999–2000. Dropout rates begin during middle school and increase significantly during high school. In 1999–2000 only 80 percent of secondary school-aged children were enrolled in secondary school. Dropout rates are significantly higher in rural areas, where there is a shortage of high schools within easy commuting distance. Although educational opportunities for girls improved after the revolution, the dropout rate is still higher for girls. Although 86 percent of girls of eligible age attended primary school, only 77 percent attended secondary school.
Iran has more than 30 tuition-free public universities and many other institutes of higher learning. These include medical universities and specialized colleges providing instruction in teacher training, agriculture, and other subjects. In all, only 10 percent of Iranians of relevant age were enrolled in institutions of higher learning in 1999–2000. Tehrān serves as a center for higher education, with more than 15 universities and numerous colleges and institutes. Other important universities are located in Hamedān, Eşfahān, Shīrāz, and Tabrīz. In addition to the public system, Iran has a private system of higher education that consists of theological colleges and the Islamic Free University, which has been developing campuses in cities throughout the country since its establishment in the late 1980s.
Iranian society in the early 20th century consisted of a narrow ruling elite (the Qajar dynasty monarch and his extended family, court-appointed officials in Tehrān and provincial capitals, major landlords, and chiefs of large nomadic tribes); a middle tier, including urban bazaar merchants, the Shia clergy, and artisans; and a large, poor segment comprising mostly share-cropping peasants and nomads but also some town dwellers engaged in service-sector trades. Following the overthrow of the Qajar dynasty in 1925, Reza Shah Pahlavi implemented wide-ranging economic development programs that stimulated the industrialization and urbanization of the country. These changes led to the emergence of two new, urban social groups: a middle class of professionals and technocrats (technical experts) and a working class engaged in manual and industrial labor. Reza Shah’s son and successor, Mohammad Reza Shah Pahlavi, continued the development programs, and the two new social groups gradually expanded.
By the late 1970s, however, the professional and technocratic middle class had divided into secular and religious factions. Both groups contributed to the overthrow of the shah in 1979; the secular group objected to the autocratic rule and economic corruption of the monarchy, while the religious group feared that the shah’s embrace of the West threatened traditional Islamic morality. The religious middle class, in alliance with the Shia clergy and under the leadership of Ayatollah Ruhollah Khomeini, gradually split from the secular middle class and consolidated power after the revolution. This group pursued an accelerated industrialization program, causing further expansion of the middle-income population from 15 percent of the total population in 1979 to 40 percent by 1996. The working class also expanded, while the peasant and nomad populations decreased; together these three low-income groups accounted for 53 percent of the population. High-ranking officials, physicians, and entrepreneurs made up the upper-income group (7 percent of the population).
Codes of personal conduct and group behavior that far predate the Islamic conquest of the 7th century continue to influence Iranian culture. Enduring cultural values include obligations to extended family, hospitality toward guests, and striving to act morally. However, social changes during the 20th century have affected these values. For example, the new professional middle class began living in nuclear family (consisting only of father, mother, and children), rather than extended family, residences. Busy lifestyles in large cities and eight-hour workdays proved incompatible with the custom of spontaneously inviting friends home for a meal. The increase in educational opportunities for girls since 1979 raised expectations among women for work opportunities outside the home. The rapid expansion of the middle class since the revolution has stimulated the growth of a consumer society in which various material goods are perceived as status symbols.
The 1979 revolution was heavily imbued with religious rhetoric. Its leaders subsequently banned many forms of entertainment that they considered sinful, including casinos, nightclubs and dance halls, movies that featured nudity or sexual themes, and musical genres such as pop and rock. For more wholesome entertainment, the government encouraged Iranian traditional and Western classical music, new films emphasizing family values, and recreational and sports facilities segregated by gender. Both men and women were required to dress modestly in public. For women, modest dress, or hejab, meant covering their hair with a scarf and having no exposed flesh other than their hands and faces; for men it meant wearing long trousers and long-sleeve shirts.
The population gradually adapted to the various restrictions and continued to enjoy pre-revolutionary leisure activities such as attending sports events, especially soccer, the national pastime. The general decline in public entertainment venues contributed to an increase in home entertaining. Popular foods at such gatherings include fresh seasonal fruit, greens, and nuts. Also popular are traditional Iranian dishes of steamed rice served with minced lamb and chicken kebabs cooked over charcoal or with traditional stews made with simmered meat, fruits, legumes, and spices. Tea is always served to guests in the home and the workplace; fruit juices and carbonated beverages also are popular. The sale and consumption of alcoholic beverages has been prohibited since 1979, although there is a black market for bootleg vodka and wine. Other general recreational and leisure activities include hiking, picnicking, watching television and videos, and making seasonal visits to Caspian Sea beaches and various historical sites and religious shrines. In large cities, shopping and attending movies, concerts, theaters, museums, and poetry readings also are popular.
Although government programs have reduced the number of families with annual incomes below the officially defined poverty line from 47 percent in 1979 to 19 percent in 1996, poverty continues to be a major social problem. To lessen the impact of poverty, the government provides low-income families with various subsidies for food, fuel, and utilities. Health care services remain inadequate in rural areas. Another serious social problem is the widespread recreational use of illegal drugs, especially among young men, despite the government’s heavy use of the print and broadcast media to educate the public about the harmful effects of addiction and drug-related crime.
Public social services in Iran include a national health insurance program that provides free or low-cost health care in government-run city hospitals and village clinics. A social security program, funded by a special tax on wages and salaries, provides pensions for retired public sector employees and some private sector employees. It also provides survivor benefits to widows of deceased retirees and veterans killed in action, disability payments to family heads incapacitated by work-related injuries or catastrophic illnesses, and special payments for minor-aged children of deceased workers. Numerous private organizations also provide various social services for low-income people.
Iranian art forms have a long tradition and
distinctive style, as exemplified in architecture, carpets, ceramics, metalware,
painting, and woodwork. Government patronage of artists dates from more
than 2,000 years ago. Aesthetic ideals predating the Islamic conquest of the 7th
century, such as stylized figural representation and geometric shapes,
influenced the evolution of art in Iran during the early Islamic period
(650-1220). Examples of elaborately decorated bronze, ceramic, gold, and silver
objects from this period are preserved in museums. Persian poetry also developed
during this time, and works by several poets of the period are considered
classic literature. During the Safavid dynasty (1501-1722), considered a golden
age for Iranian art, miniature painting and architecture reached their highest
point of development. In the 20th century Iranian artists and writers began
experimenting with new styles and techniques, incorporating European and East
Asian influences into their work.
From its beginnings in the 9th century, Modern Persian literature was dominated by poetry. Important poets of the 9th through the 12th century include Rudaki, noted for his qasidas (panegyrics, or written works of praise); Firdawsi, who wrote the famous epic of pre-Islamic Iran, the Shahnameh (completed in 1010); Omar Khayyam, author of the famous Rubáiyát; and Nezami, who wrote the collection known as Khamseh (Quintet). Persian poetry reached its height in the 13th and 14th centuries with mystical poets Jalal al-Din Rumi, Sa’di, and Hafiz. Subsequently, Persian literature declined, and for nearly five centuries both poetry and prose remained uninspired imitation of past masters. A literary revival began in the late 19th century and has continued to the present. Fiction, especially in the form of the short story, has emerged as a new and important genre. Modern Iranian writers include Mashid Amirshahi, Simin Daneshvar, Ismail Fassih, Houshang Golshiri, and Moshen Makhmalbaf (who also directs films). Writers may explore many themes that were prohibited prior to the 1979 revolution, such as political freedom, rebellion against authority, satire of monarchy, and fictional accounts of suffering under the Pahlavi dynasty. However, since the revolution, works deemed to be anti-religious have been banned. See also Persian Literature.
Persian art and architecture first developed in the
time of Persian king Cyrus the Great (6th century
bc) and experienced a renaissance
during the Sassanid dynasty (224-651 ad).
After the Islamic conquest, the mosque became the major building type, and
se
veral new styles of painting developed and thrived during the Safavid era
(1501-1722).
The 1979 revolution ushered in a period of renewed
creativity in fine and applied arts. The proliferation of exhibits sponsored by
the Ministry of Culture, by various museums, and by private galleries inspired
artistic creativity in mediums as diverse as calligraphy, graphic art, painting,
photography, pottery, and sculpture. The boom in public and private construction
following the Iran-Iraq War (1980-1988) provided new opportunities for
architects. Most new buildings have tended to be updated versions of the
structures they replaced. Some younger architects have been experimenting with
designs that incorporate traditional architectural motifs into contemporary
buildings. In textile arts, younger designers continue to experiment with new
patterns and color schemes for hand-knotted carpets and woven coverings. See
also Iranian Art and Architecture.
Iranian musical tradition is marked by unique vocal styles and rich solo instrumental performance. Since the 1979 revolution, there has been a major revival of interest in Iranian traditional and folk music, both of which are aired regularly on government-run radio and television stations. Popular nationally known singers and performers of traditional music include Hossein Alizadeh, Mohammad Reza Lofti, Shahram Nazari, and Mohammad Shajarian. However, every town has locally famous singers. Traditional musical instruments include the kamánche, or spiked fiddle; the santur, a stringed instrument similar to the hammer dulcimer; the setar, which resembles a lute; and the tar, an ancestor of the guitar. Many Iranian musicians have acquired international reputations as virtuoso performers of these instruments. The most popular folk troupes are those performing Azeri Turkish, Kurdish, and Luri music, as well as Persian seafaring songs from the Persian Gulf coast.
A type of passion play called ta’zia, depicting events of Shia religious history, developed during the Safavid era (1501-1722) and enjoyed great popularity during Qajar rule (1794-1925). Influenced by increased European contact, playwrights of the 19th and early 20th centuries wrote satires that often called for reform. During the Pahlavi dynasty (1925-1979), plays were typically patriotic and pro-Western. Since the 1979 revolution, which sought to promote Islamic values, the government has encouraged playwrights but has prohibited plays considered immoral or antireligious.
Iranian filmmakers produced the first Iranian feature films in the early 1930s and have made more than 1,000 movies since then. Iranian directors often also write the screenplays for their movies. During the 1990s several Iranian films won awards at international film festivals. Award-winning filmmakers include Bahram Bayzai, Abbas Kiarostami, Majid Majidi, Mohsen Makhmalbaf, and Dariush Mehrjui. In 1997 Kiarostami's Taste of Cherry won the prestigious Palme d’Or (Golden Palm) award for best film at the Cannes Film Festival, and in 1999 Majidi’s Children of Heaven was nominated for an Academy Award for best foreign film of 1998.
Of Iranian cities, Tehrān has the largest number of museums, including Iran Bastan Museum (Museum of Ancient Iran), which displays archaeological objects unearthed at Iran's pre-Islamic sites. Tehrān’s museums also include Abgineh va Sofalineh Museum, a museum of glass art and ceramics with hundreds of chronologically displayed exhibits, and the Museum of Contemporary Art, which specializes in Iranian and international painting and sculpture. Other major museums are located in Eşfahān, Mashhad, Qom, and Shīrāz. Since 1979 the government has constructed museums in more than 25 provincial capitals. The National Library of Iran, located in Tehrān, houses many valuable manuscripts and historical documents. Public libraries exist in hundreds of municipalities.
Although agriculture historically was the most
important sector of Iran’s economy, its share of the gross domestic product
(GDP) has been declining since the 1930s due to the rise of manufacturing.
Meanwhile, the mining sector, which is dominated by the production of oil, has
grown rapidly since Iran nationalized its oil fields in the 1950s. Factory
manufacturing has experienced periods of both rapid growth and stagnation. Trade
and commerce activities have expanded with the country's increasing
urbanization. During the late 1970s the Iranian economy appeared ready to grow
to a level on par with the world’s developed countries, but the 1979 revolution
and the subsequent eight-year war with Iraq strained all economic sectors.
However, the need to produce for the war effort actually spurred
industrialization, as did government spending on infrastructure development.
In the mid-1990s the service sector contributed the largest percentage of the GDP, followed by industry (mining and manufacturing) and agriculture. About 60 percent of the government's budget came from oil and natural gas revenues, and 40 percent came from taxes and fees. Government spending contributed to average annual inflation rates exceeding 20 percent. In 2001 the GDP was estimated at $114 billion, or $1,770 per capita. Because of these figures and the country’s diversified but small industrial base, the United Nations classifies Iran's economy as semi-developed.
Government planning plays an important role in Iran’s economy. Since the late 1940s the government has designed and implemented multiyear planning programs with the goal of industrial diversification. After the 1979 revolution, the government continued the industrialization that the shah had pursued but emphasized economic self-sufficiency, which required greater investment in agriculture. However, the flight abroad in 1978 and 1979 of most of the social and political elite, along with their capital (estimated at more than $28 billion), combined with the costly war with Iraq in the 1980s, left Iran’s economy severely damaged.
In the 1990s the Iranian government sought to privatize state industries to stimulate the ailing economy. In 1991 about 45 percent of large industry was government-owned. The majority of heavy industry—including steel, petrochemicals, copper, automobiles, and machine tools—was in the public sector, while most light industry was privately owned. That year the government announced plans to privatize 400 state-run factories; however, the actual sale of these companies proceeded slowly. A five-year development plan for the period from March 1995 to March 2000 calls for the creation of 2 million new jobs, primarily through stimulation of the private sector, especially industry.
In 2001 Iran’s labor force was estimated at 20.4 million, of which women accounted for 28 percent. Unemployment stood at about 10 percent for the labor force as a whole, although the unemployment rate for women and men aged 16 to 25 exceeded 20 percent. The agriculture and service sectors employed the greatest number of workers. Although there are numerous government-affiliated trade associations, there are no independent labor unions in Iran.
Urbanization has contributed to significant growth in the service sector. In 2001 the sector ranked as the largest contributor to the GDP (48 percent) and employed 45 percent of workers. Important service industries include public services (including education), commerce, personal services, professional services (including health care), and tourism. The tourist industry declined dramatically during the war with Iraq in the 1980s but had revived significantly by the mid-1990s. About 1,402,000 foreign tourists visited Iran in 2001; 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. The most popular tourist destinations are Eşfahān, Mashhad, and Shīrāz.
Iran’s agricultural sector contributed 19 percent of the GDP in 2001 and employed 23 percent (1996) of the labor force. Since 1979 commercial farming has replaced subsistence farming as the dominant mode of agricultural production. Some northern and western areas support rain-fed agriculture, while other areas require irrigation for successful crop production. Wheat, rice, and barley are the country’s major crops. Total wheat and rice production fails to meet domestic food requirements, however, making substantial imports necessary. Other principal crops include potatoes, legumes (beans and lentils), vegetables, fruits, fodder plants (alfalfa and clover), oil seeds, nuts (pistachios, almonds, and walnuts), cotton, sugarcane, sugar beets, herbs, spices (including cumin, sumac, and saffron), tea, and tobacco. Honey is collected from beehives, and silk is harvested from silkworm cocoons. Livestock products include lamb, beef, goat meat, poultry, eggs, milk, butter, cheese, wool, and leather. Major agricultural exports include fresh and dried fruits, nuts, animal hides, processed foods, and spices.
Although the mining sector contributed 17 percent of the GDP in 1996, mineral extraction in Iran employs less than 1 percent of the labor force. Petroleum has long been the country’s most important mineral resource. Since 1913 Iran has been a major oil exporting country. In the late 1970s it ranked as the fourth largest oil producer and the second largest oil exporter in the world. Following the 1979 revolution, however, the government reduced daily oil production in accordance with an oil conservation policy. Further production declines occurred as result of damage to oil facilities during the war with Iraq. Oil production began increasing in the late 1980s due to the repair of damaged pipelines and the exploitation of newly discovered offshore oil fields in the Persian Gulf. By 2001 Iran’s annual oil production was 1.4 billion barrels; two-thirds was exported. Iran also has the world's second largest reserves of natural gas; these are exploited primarily for domestic use.
Although the petroleum industry provides the majority of economic revenues, about 75 percent of all mining sector employees work in mines producing minerals other than oil and natural gas. These include coal, iron ore, copper, lead, zinc, chromium, barite, salt, gypsum, molybdenum, mica, silica, talc, uranium, and gold. The mines at Sar Cheshmeh in Kermān Province contain the world's second largest lode of copper ore. Large iron ore deposits lie in central Iran, near Bafq, Yazd, and Kermān.
Iran has a long tradition of producing artisan goods, including carpets, ceramics, copperware and brassware, glass, leather goods, textiles, and woodwork. Iran’s rich carpet-weaving tradition dates from pre-Islamic times, and it remains an important industry. Large-scale manufacturing in factories began in the 1920s and developed gradually. During the Iran-Iraq War, Iraq bombed many of Iran’s petrochemical plants, and the large oil refinery at Ābādān was badly damaged and forced to halt production. Reconstruction of the refinery began in 1988 and production resumed in 1993. However, the war also stimulated the growth of many small factories producing import-substitution goods and materials needed by the military. By 2001 manufacturing contributed 16 percent of the GDP and employed 18 percent of the labor force. Important manufactured products included petrochemicals, steel, carpets, textiles, cement, processed foods (including refined sugar), copper wire, aluminum, electronics, refrigerators, footwear, appliances, paints, plastics, automobiles, machinery, railroad cars, leather, furniture, cigarettes, utensils, glass, paper, and handicrafts.
Although they contribute very little to the GDP and employ a small percentage of workers, fishing and logging are important industries in specific regions. Logging takes place primarily in the forests of the Elburz Mountains, where various deciduous and conifer trees are harvested for construction, furniture, pulp, industrial uses, and fuel. Fishing fleets operate out of several ports on the Caspian Sea, the Persian Gulf, and the Gulf of Oman. Caviar harvested from Caspian Sea sturgeon is an important export item. Grouper, shrimp, and tuna caught in the Persian Gulf are important for the domestic and export markets. Various species of rock lobsters are caught in the Gulf of Oman.
Between 1979 and the mid-1990s Iran quadrupled its electric power output through the construction of several new natural gas, combined cycle (using both gas and steam), and hydroelectric power stations. Thermal plants supply 97 percent of the country’s electricity, and hydroelectric facilities provide most of the rest. In 1975 the government began building a nuclear power plant at Būshehr, on the Persian Gulf coast. The partially completed plant was bombed during the war with Iraq. In 1995 Russia signed an agreement to finish construction of the plant.
Iran has an extensive paved road system linking most of its towns and all of its cities. In 1998 the country had 167,157 km (104,000 mi) of roads, of which three-fifths was paved. There were 30 passenger cars for every 1,000 inhabitants. Trains operated on 6,688 km (4,156 mi) of railroad track. The country’s major port of entry is Bandar-e ‘Abbās on the Strait of Hormuz. After arriving in Iran, imported goods are distributed throughout the country by trucks and freight trains. The Tehrān- Bandar-e ‘Abbās railroad, opened in 1995, connects Bandar-e ‘Abbās to the railroad system of Central Asia via Tehrān and Mashhad. Other major ports include Bandar-e Anzalī and Bandar-e Torkeman on the Caspian Sea and Korramshahr and Bandar-e Khomeynī on the Persian Gulf. More than 30 cities have airports that serve passenger and cargo planes. Iran Air, the national airline, was founded in 1962 and operates domestic and international flights. All large cities have mass transit systems using buses, and several private companies provide bus service between cities. Tehrān and Eşfahān are in the process of constructing underground mass transit rail lines.
The press in Iran is privately owned and reflects a diversity of political and social views. A special court has authority to monitor the print media and may suspend publication or revoke the licenses of papers or journals that a jury finds guilty of publishing antireligious material, slander, or information detrimental to the national interest. In 1996, 32 daily and 152,534 nondaily newspapers were in circulation. The majority of these are published in Persian, but newspapers in English and other languages also exist. The most widely circulated periodicals are based in Tehrān. Popular daily and weekly newspapers include Hamshahri, Jomhuri-ye Islami, Kayhan, Resalat, Salaam, Sobh-e Emrooz, and the Teheran Times (an English-language paper).
The government runs the broadcast media, which in 1995 included 3 national and more than 50 local radio stations, as well as 3 national and 28 local television stations. In 2000 there were 252 radios and 158 television sets in use for every 1,000 residents. There were 169 telephone lines and 33 personal computers for every 1,000 residents. Computers for home use became more affordable in the mid-1990s, and since then demand for access to the Internet has developed. In 1998 the Ministry of Posts and Telecommunications began selling Internet accounts to the general public.
In 2000 Iran exported 843 million barrels of crude oil per day. In the mid-1990s annual foreign currency revenues varied depending on the international price of oil; non-oil exports brought in $4 to $5 billion annually. Major non-oil exports include carpets, chemicals, steel, fresh and dried fruits, nuts, animal hides, textiles, copper, and caviar. The country’s leading purchasers are Japan, South Korea, Italy, South Africa, and Greece. Since the value of Iran's imports generally is less than the value of its exports, the country maintained a favorable balance of trade for most years between 1989 and 1997. Principal imports include machinery, chemicals, transport equipment, iron and steel, wheat, rice, live animals, and scientific instruments. Primary suppliers of imports are Germany, Japan, Italy, France, the United Kingdom, Argentina, and South Korea.
Iran has had no direct trade with the United States since 1995, when the U.S. government banned all commercial and financial transactions between U.S. companies and Iranian public and private entities. The United States took this action because it believed Iran was planning to develop weapons of mass destruction and was supporting international terrorism. Iran is a founding member of the World Bank, the International Monetary Fund, and the Economic Cooperation Organization (an organization promoting economic and cultural cooperation among Islamic states).
Iran’s unit of currency is the rial. The official exchange rate averaged 1,754 rials to the U.S. dollar in 2001. However, rials are exchanged on the unofficial market at a rate as much as four times higher. In 1979 the government nationalized all private banks and announced the establishment of a banking system whereby, in accordance with Islamic law, interest on loans was replaced with handling fees; the system went into effect in the mid-1980s. The banking system consists of the central bank, which issues currency; eight commercial banks that are headquartered in Tehrān but have branches throughout the country; two development banks; and a housing bank that specializes in home mortgages. The Tehrān Stock Exchange trades the shares of more than 400 registered companies.
The Safavid dynasty established Iran as a monarchy under a shah, or king, in 1501. Although the ruling dynasty changed in the 18th century, the system of government did not change significantly until 1906, when a popular revolution forced the shah to accept a constitution that limited his powers. The 1906 constitution remained law until 1979, but after 1925 it was ignored in practice by the Pahlavi dynasty shahs, who created a highly centralized government over which they ruled as virtual dictators. Beginning in the early 1950s, popular disaffection with arbitrary rule increased gradually, culminating in the 1979 Islamic revolution. This revolution replaced the monarchy with a republican form of government guided by the principles of Shia Islam. Shia clergy who had played a key role in mobilizing opposition to the shah obtained important positions in the postrevolutionary government. The principal religious figure, Ayatollah Ruhollah Khomeini, was accepted widely as the country's leader even though he did not participate in the actual governance of the country. Suspicious of central authority, the new rulers created a system under which the executive, judicial, and legislative branches of government were separate and could check one another's exercise of power.
Although the clergy continued to dominate the highest ranks of the government in the 1990s, it was divided into liberal and conservative factions. Liberal clergy wanted to relax some of the religious restrictions on Iranian society. In the late 1990s conservatives controlled the legislature and the judiciary, and liberals under President Mohammed Khatami controlled the executive. Although Khatami won the 1997 presidential election by a landslide, conservatives sought to undermine his authority in many ways. In 1998 an Iranian court, in a trial that was widely seen as politically motivated, convicted the liberal mayor of Tehrān of corruption for illegally funneling city funds into Khatami’s election campaign. In 1999 liberals won control of most local council seats in the country’s first municipal elections. Liberals won control of the legislature in 2000, and Khatami was reelected in 2001.
In the summer of 1979 a popularly elected assembly drafted the constitution of the Islamic Republic of Iran; this constitution was approved in a popular referendum in December. It named Khomeini to serve as Iran’s supreme spiritual leader, an office called velayat-e faqih (guardianship of the religious jurist; the holder of the office is the faqih), and provided for an elected assembly of senior clergy to select Khomeini’s successors. The constitution also stipulated as head of state an elected president who would choose a prime minister to be head of government, subject to legislative approval. It preserved the pre-revolutionary elected parliament, the Majlis, as the legislature. In 1989 voters approved 45 amendments to the constitution, the most important of which downgraded the religious qualifications for the faqih, eliminated the office of prime minister, and made the president both head of state and head of government. The Majlis set 15 as the minimum age for voting.
The faqih generally oversees the operation of the government to ensure that its policies and actions conform to Islamic principles. The faqih is a spiritual leader whose religious authority is above that of the president and any other officials. However, in keeping with the practice established by Khomeini, the faqih is expected to refrain from involvement in the day-to-day affairs of governance. An 83-member Assembly of Experts, popularly elected every eight years, is responsible for choosing the faqih (or a council of three to five faqihs, if there is no consensus on a single faqih) from among the most politically and religiously qualified Shia clergy.
The chief executive and head of state is the president, who is elected to a four-year term and may be reelected to one additional term. The president may appoint as many vice presidents as he deems appropriate; he also appoints a cabinet of ministers. Vice presidents do not need legislative approval, but all cabinet ministers chosen by the president must receive a confirmation vote from the Majlis. The faqih is empowered to dismiss a president who has been impeached by the Majlis.
Legislative authority is vested in the Majlis, a single-chamber parliament. Its 290 members, 5 of whom represent non-Muslim religious minorities, are popularly elected for four-year terms. The Majlis can force the dismissal of cabinet ministers by no-confidence votes and can impeach the president for misconduct in office. Although the executive proposes most laws, individual deputies of the Majlis also may introduce legislation. Deputies also may propose amendments to bills being debated.
A 12-member Council of Guardians ensures that all legislation enacted by the Majlis conforms to Islamic principles and the constitution. The Council of Guardians also approves candidates for presidential, Majlis, and other elections. In 1997 the conservative-controlled Council of Guardians used this power to disqualify many liberal candidates from the election to the Assembly of Experts. Members of the Council of Guardians serve six-year terms. Six of the members must be clergymen appointed by the faqih, and six must be Muslim lawyers appointed by the judiciary. Conflicts between the Council of Guardians and the more secular Majlis led Khomeini in 1988 to create the Expediency Council, a body charged with resolving legislative disputes. The Expediency Council comprises the six clergymen from the Council of Guardians and seven leading government officials.
Islamic law was introduced into Iran’s legal system following the Islamic revolution of 1979. The country’s highest judicial body is the Supreme Council of Justice, a five-member group of senior clergy that supervises the appointment of all judges and codifies Islamic law. The council also drafts all legislation pertaining to civil and criminal offenses; the Majlis then debates the drafts and may amend any proposed bill before voting to accept or reject it. The faqih appoints the head of the Supreme Council of Justice; constitutional amendments passed in 1989 combined this office with that of chief justice of the Supreme Court.
The Supreme Court reviews decisions of the lower courts and renders judgments regarding their conformity to Islamic legal principles and the constitution. There are three types of lower courts in Iran: revolutionary, civil, and criminal. Revolutionary courts try cases involving antirevolutionary behavior, a broadly defined category that includes crimes ranging from plots to overthrow the government by violent means to trafficking in illegal drugs. Civil courts hear suits involving disputes between individuals or corporate entities. Criminal courts deal with murder and theft. In addition, there are special administrative courts, such as the Court of the Clergy and the Press Court, that hear cases of professional misconduct. Responsibility for the administration of courts is vested in the Ministry of Justice. More than 100 crimes—including murder, drug trafficking, spying, terrorism, treason, rape, adultery, and corruption—carry the possibility of a death sentence.
Iran is divided into 28 provinces, each headed by a governor appointed by the Ministry of Interior. The provinces are further divided into counties, each headed by an executive appointed by the Ministry of Interior on the recommendation of the provincial governor. Each county includes two or more districts, which are headed by district commissioners appointed by the county executive. The districts are subdivided into urban municipalities and rural areas. Each municipality has an elected council; the rural areas encompass a number of villages, each run by elected village councils. The local councils have the power to regulate zoning and issue building permits. They also organize the provision of, and assess fees for, various public services.
Political parties developed in Iran during the 1940s. Most parties were banned after forces loyal to the shah overthrew Prime Minister Mohammad Mosaddeq and instituted martial law in 1953, although many continued to operate secretly until the 1979 revolution, when they reemerged openly. Immediately after the revolution, Iran’s leading clerics established the Islamic Republican Party (IRP), which dominated politics until it was dissolved in 1987 due to internal dissent. Following uprisings by several opposition parties in 1981, new regulations made it increasingly difficult for political groups to hold public meetings and recruit new members. An official body was created to license political parties, but since 1987 it has recognized the legal existence of only a few parties.
Nevertheless, the government tolerates political activities by various associations that function as de facto parties by endorsing candidates for legislative and presidential elections. One such unofficial party, the Jamiyat-e Ruhaniyan Mobarez (Association of Militant Clergy), generally supports legislation favorable to private business. The Majma-e Ruhaniyat-e Mobarez (Society of Militant Clergy), which dominated the Majlis from the late 1980s until 1992, advocates government regulation of the economy and progressive income taxes to redistribute wealth equitably. The Kargozaran-e Sazandegi (Servants of Construction), followers of former president Ali Akbar Hashemi Rafsanjani, support a strong government role in development projects. The Nezhat-e Azadi (Liberation Movement of Iran) stresses the need for expanding and protecting civil liberties. The (Hezb-e Mosha Karat-e Islami Iran (Islamic Iran Participation Party), supporters of Khatami, stress the need to create a civil society based on the rule of law.
Upon the recommendation of the president, the faqih appoints a joint chief of staff to coordinate the five branches of the armed forces. These consist of an army (totaling 350,000 forces in 1997), an internal security force known as the Revolutionary Guard (125,000), a rural police force (40,000), a navy (20,600), and an air force (45,000). In addition, a total of 200,000 men and women were enlisted in a volunteer reserve force, the Basij. A two-year period of military service is required of all male citizens of Iran aged 18 and older. The Ministry of Defense exercises general supervision over the armed forces. In general, the military is under the tight control of the civilian government, and armed forces personnel are encouraged to avoid involvement in partisan politics.
Iran is a charter member of the United Nations (UN) and belongs to all of its specialized agencies. The country is also a founding member of the Organization of the Islamic Conference (OIC), which promotes solidarity among nations where Islam is an important religion, and the Organization of Petroleum Exporting Countries (OPEC). Iran also belongs to the International Atomic Energy Agency (IAEA).
For the history of Iran before the Muslim conquest in the 7th century, see Persia.
Arab Muslim armies began their conquest of the Persian Sassanian Empire in ad 636 and during the next five years conquered all of Iran, with the exception of the Elburz Mountains and the Caspian coastal plain. They finally put an end to the Sassanid dynasty in 651. For the next two centuries, most of Iran (which at that time extended beyond Herāt in what now is western Afghanistan) remained part of the Arab Islamic empire. The caliphs (successive Islamic leaders) ruled initially from Medina in present-day Saudi Arabia, then from Damascus, Syria, and finally from Baghdād, Iraq, as each city became the seat of the caliphate. Beginning in the late 9th century, however, independent kingdoms arose in eastern Iran; by the mid-11th century, the Arab caliph in Baghdād had lost effective control of virtually all of Iran, although most of the local dynasties continued to recognize his religious authority.
From the time of Islamic conquest, Iranians gradually converted to Islam. Most had previously followed Zoroastrianism, the official state religion under the Sassanid dynasty, but minority groups had practiced Christianity or Judaism. By the 10th century the majority of Iranians probably were Muslims. Most Iranian Muslims adhered to orthodox Sunni Islam, although some followed various sects of Shia Islam. The Ismailis, a Shia sect, maintained a small but effectively independent state in the Rūdbār region of the Elburz Mountains from the 11th through the 13th century. Iran's unique identity as a bastion of Jafari, or Twelver, Shia Islam (which constitutes the main body of Shia Islam today) did not develop until the 16th century.
In the 11th century Turkic tribes began migrating to Iran, settling primarily in the northwest. The Seljuk Turks (see Seljuks), who had converted to Sunni Islam in the 10th century, defeated local rulers and established dynasties that ruled over most of the country until the Mongol invasions in the 13th century. Mongol rule proved disastrous for Iran. The Mongols destroyed major cities such as Ardabīl, Hamadān, Marāgheh, Neyshābūr, and Qazvīn, and they killed almost all of the inhabitants as punishment for resistance. Ray and Tus, the largest and most important cities in Iran, were destroyed by the Mongols and never rebuilt. The Mongols devastated many regions, especially Khorāsān and Māzandarān, by destroying irrigation networks and cropland. The harsh rule of the Mongols contributed to a continuing economic decline throughout the 13th century.
Prior to 1295 Iran's Mongol rulers, followers of shamanism or Buddhism, did not accept the Islamic faith. Their official indifference or open hostility toward Islam stimulated the transformation of Sufi brotherhoods into religious paramilitary organizations. Although nominally Sunni, many of these brotherhoods became increasingly tolerant of Shia ideas, even incorporating these ideas into their own belief systems. In 1295 Mongol ruler Ghazan Khan, himself a convert to Islam, restored Islam as the state religion, further bolstering the growth of new Islamic ideas.
Ghazan and his immediate successors also adopted policies that reversed Iran's economic decline. In the late 13th and early 14th centuries, cities that had escaped the destruction of the Mongol invasions, such as Eşfahān, Shīrāz, and Tabrīz, emerged as new centers of cultural development. However, from 1335 to 1380 civil strife weakened central authority. Between 1381 and 1405 invasions by Turkic conqueror Tamerlane destroyed more of Iran’s cities and undid most of the progress Ghazan had achieved.
During the 15th century several competing families and tribes, mostly of Turkic origins, ruled over various parts of Iran. Notable among them were the Safavids, who headed a militant Sufi order founded in the northwest by Shaikh Safi of Ardabīl in the early 14th century. His descendant, Ismail I, conquered first Tabrīz and then the rest of Iran. In 1501 he proclaimed himself shah (king), a title commonly used by Iranian rulers in pre-Islamic times. This marked the beginning of the Safavid dynasty and was the first time since the 7th century that all of Iran was unified as an independent state. Ismail embraced Jafari Shia Islam, established it as the state religion, and began to convert the largely Sunni population to this Shia sect.
Ismail used the new religion to mobilize armies against the Ottomans—Sunni Muslims who controlled a vast empire to the west. Intermittent warfare between the Safavids and the Ottoman Empire continued for more than 150 years as successive rulers of each accused one another of heretical beliefs. Although this lengthy conflict helped shape Iran's identity as a Shia country, the real conflict between the Safavids and the Ottomans was over territory, especially the Zagros Mountains region and the fertile plains of present-day Iraq. In 1509 Ismail gained control of the Iraqi territory, but it fell into Ottoman hands when Ottoman ruler Süleyman I conquered Baghdād in 1534.
After several unsuccessful campaigns, the Safavids finally recaptured Baghdād in 1623 under Abbas I. (They held the city for 15 years before the Ottomans gained permanent control in 1638.) During his reign, Abbas moved the Safavid capital from Tabrīz, which was dangerously close to the Ottoman border and had been occupied briefly by the Ottomans, to the centrally located city of Eşfahān. He embellished Eşfahān with many bridges, mosques, palaces, and schools. Most of these structures still stand, and they are among the best-preserved examples of Islamic architecture in the world. Abbas also encouraged trade with Europe, especially England and The Netherlands, whose merchants bought Iranian carpets, silk, and textiles.
The Safavid empire gradually declined after the reign of Abbas II ended in 1666. To finance lavish personal lifestyles, later shahs imposed heavy taxes that discouraged investment and encouraged corruption among officials. Shah Sultan Hosain, who ruled from 1694 to 1722, tried to convert forcibly his Afghan subjects in eastern Iran from Sunni to Shia Islam. In response, an Afghan army under Mir Mahmud rebelled, marching across eastern Iran and capturing the Safavid capital of Eşfahān. After a brief siege of the city, the Afghan army executed the shah in 1722, thus ending Safavid rule of Iran. The sudden dissolution of the empire plunged Iran into a 70-year period of relative turmoil, marked by internal civil strife and efforts by Ottoman and Russian forces to occupy border zones. Military leader Nadir Shah, based in Mashhad, succeeded in freeing Iran from foreign occupation in the 1730s and soon extended his rule eastward, but his empire collapsed upon his assassination in 1747. Karim Khan Zand, based in Shīrāz, established a brief period of tranquility in the mid-1700s but was not able to extend his control over all of Iran.
In 1794 Agha Mohammad Khan defeated numerous rivals and brought all of Iran under his rule, establishing the Qajar dynasty. The Qajars were a Turkic tribe that held ancestral lands in present-day Azerbaijan, which then was part of Iran. Agha Mohammad established his capital at Tehrān, a village near the ruins of the ancient city of Ray (now Shahr-e Rey). Agha Mohammad’s nephew and successor, Fath Ali Shah, ruled from 1797 to 1834. Under Fath Ali Shah, Iran went to war against Russia, which was expanding from the north into the Caucasus Mountains, an area of historic Iranian interest and influence. Iran suffered major military defeats during the war. Under the terms of the Treaty of Gulistan in 1813, Iran recognized Russia's annexation of Georgia and ceded to Russia most of the north Caucasus region. A second war with Russia in the 1820s ended even more disastrously for Iran, which in 1828 was forced to sign the Treaty of Turkmanchai acknowledging Russian sovereignty over the entire area north of the Aras River (territory comprising present-day Armenia and Azerbaijan).
During the reign of Mohammad Shah, from 1834 to 1848, Russia began expanding its political influence into Iran. Another world power, Britain, also took interest in the region in order to protect its growing empire in India. Because of Iran’s strategic location between the southern borders of Russia and the westernmost borders of British India, both Britain and Russia regarded an independent Iran as a convenient buffer area between the two empires. At the same time, both powers preferred Iran to have a weak central government so that they could more easily influence the country's internal affairs.
Foreign interference and territorial encroachment increased under the rule of Nasir al-Din Shah (1848-1896) and his son, Muzaffar al-Din Shah (1896-1906). Both men contracted huge foreign loans to finance expensive personal trips to Europe. Neither ruler was able to prevent Britain and Russia from encroaching into regions of traditional Iranian influence. In 1856 Britain prevented Iran from reasserting control over Herāt, which had been part of Iran in Safavid times but had been under non-Iranian rule since the mid-18th century. Britain supported the city's incorporation into Afghanistan, a country Britain helped create in order to extend eastward the buffer between its Indian territories and Russia's expanding empire. Britain also extended its control to other areas of the Persian Gulf during the 19th century. Meanwhile, by 1881 Russia had completed its conquest of present-day Turkmenistan and Uzbekistan, bringing Russia’s frontier to Iran's northeastern borders and severing historic Iranian ties to the cities of Bukhoro (Bukhara) and Samarqand. Several trade concessions by the Iranian government put economic affairs largely under British control. By the late 19th century, many Iranians believed that their rulers were beholden to foreign interests.
During the early 1900s the idea gradually spread among Iranians that the only effective way to save the country from government corruption and foreign manipulation was to make the shah accountable to a written code of laws. By 1905 this sentiment had grown into a popular movement, the Constitutional Revolution. Following a year of demonstrations and strikes, Muzaffar al-Din Shah was forced to agree to the creation of an elected parliament (the Majlis) and a constitution that limited royal power, established a parliamentary system of government, and outlined the powers of the legislature.
Britain and Russia, apparently fearing that a strong Iranian government might act too independently and threaten their interests in the region, agreed in 1907 to divide Iran into spheres in which each would exercise exclusive influence. Russia then encouraged Mohammad Ali Shah, Muzaffar’s successor who resented the constitutional limits on his authority, to dissolve the Majlis. In 1908 the shah attempted a coup against the elected government, bombing the Majlis building and dissolving the assembly. After a year of fighting between supporters of the constitution and forces loyal to the shah, the constitutionalists prevailed and deposed Mohammad Ali, who fled to Russia. His young son Ahmad Shah, vowing to respect the constitution, was installed under a regent.
The restoration of the Majlis and constitutional government failed to end foreign influence in Iran. In 1901 a British subject had been granted an exclusive 60-year concession to explore Iran for oil. Commercially valuable quantities of oil were discovered in southwestern Iran in 1908, and exports began in 1911. In 1914 the British government purchased 51 percent of the Anglo-Persian Oil Company (formed in 1909; renamed the Anglo-Iranian Oil Company, or AIOC, in 1935), and from then on behaved increasingly like a sovereign power in southwestern Iran. Meanwhile, in 1910 Russia assisted Mohammad Ali Shah in an invasion of Iran and an unsuccessful attempt to overthrow the government. The following year, Russia occupied Tabrīz and forced the Majlis to dismiss American financial advisor William Morgan Shuster, whom the Majlis had invited to Iran to reorganize the national finances; Shuster’s reforms strengthened Iran but threatened Russian and British interests.
During World War I (1914-1918), Britain and Russia, who were allies, launched attacks from Iran against the Ottoman Empire, which was allied with Germany. Although Iran proclaimed neutrality in the war, several battles were fought in western Iran between Russian and Ottoman forces. These battles destroyed many villages, killed several hundred Iranian civilians, and caused near-famine conditions that probably caused the death of several thousand more. The inability of the Iranian government to protect the country provoked rebellions and autonomy movements in northern Iran between 1915 and 1921.
Meanwhile,
