Iran (Persian: ايران, /irɒn/↔[ʔiˈɾɒn] (help·info)), officially the Islamic Republic of Iran[5], formerly known internationally as Persia until 1935, is a country in Central Eurasia, located on the northeastern shore of the Persian Gulf. Since 1949, both the names "Persia" and "Iran" are used, however, Iran is used for an official and political context.[6][7] The name Iran is a cognate of Aryan, and means "Land of the Aryans".[8][9][10]
The 18th largest country in the world in terms of area at 1,648,195 km², Iran has a population of over seventy million. It is a country of special geostrategic significance due to its central location in 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 and condominium, 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, and on the west by Turkey and Iraq. 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,[11][12] and occupies an important position in international energy security and world economy as a result of its large reserves of petroleum and natural gas.
Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 4000 BC.[13][14][15] The Iranian Medes unified Iran into a kingdom in 625 BC.[2] They were succeeded by three Iranian Empires, the Achaemenids, Parthians and Sassanids, which governed Iran for more than 1000 years. After centuries of foreign occupation and short-lived native dynasties, Iran was once again reunified as an independent state in 1501 by the Safavid dynasty[16] — who promoted TwelverShi'a Islam[17] as the official religion of their empire, marking one of the most important turning points in the history of Islam.[18] Iran had been a monarchy ruled by a Shah, or emperor, almost without interruption from 1501 until the 1979 Iranian Revolution, when Iran officially became an Islamic republic on 1 April 1979.[19][20]
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.[

Iran is the eighteenth largest country in the world.[25] Its area roughly equals that of the United Kingdom, France, Spain, and Germany combined, or slightly less than the state of Alaska.[26][27] Its borders are with Azerbaijan (432 km/268 mi) 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. Iran's area is 1,648,000 km² (approximately 636,300 sq mi).[28]

Iran consists of the Iranian Plateau with the exception of the coasts of the Caspian Sea and Khuzestan. 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 latter contains Iran's highest point, Mount Damavand at 5,610 m (18,405 ft), which is not only the country's highest peak but also the highest mountain on the Eurasian landmass west of the Hindu Kush.[29] 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 Sea of Oman.
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 nearly fall below freezing and it remains humid for the rest of the year. Summer temperatures rarely exceed 29 °C (85 °F).[30][31] Annual precipitation is 680 mm (27 in) in the eastern part of the plain and more than 1,700 mm (67 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 (eight in) of rain, and have occasional deserts.[31] Average summer temperatures exceed 38 °C (100 °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 (five to fourteen inches).[31] Iran's wildlife is composed of several animal species including bears, gazelles, wild pigs, wolves, jackals, panthers, Eurasian lynx, and foxes. Other domestic animals include, sheep, goats, cattle, horses, water buffalo, donkeys, and camels. The pheasant, partridge, stork, eagles and falcon are also native to Iran.
Iran is divided into thirty 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%.[32] The United Nations predicts that by 2030 80% of the population will be urban.[33] 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.[34]Tehran, with population of 7,705,036, is the largest city in Iran and is the Capital city. Tehran is home to around 11% of Iran's population. 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 2.8 million is the second largest Iranian city and the centre of the province of Razavi Khorasan. Mashahd is one of the holiest Shi'a 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.[35][36] Another major Iranian city is Isfahan (population 1,986,542). Isfahan is the capital of Isfahan Province. The Naghsh-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 eleventh to the 19th century. The growth of suburb area around the city has turned Isfahan to the second most populous metropolitan area (3,430,353).[37] The other major Iranian cities are Karaj (population 1,732,275), Tabriz (population 1,597,312) and Shiraz (population 1,227,331). Karaj is located in Tehran province and is situated 20 km west of Tehran, at the foot of Alborz mountains, however the city is increasingly becoming an extension of the metropolitan Tehran. Pre-Islamic Statehood (625 BC–651 AD)
Achaemenid empire at its greatest extent about 500 BC
In 499 BC Athens lent support to a revolt in Miletus which resulted in the sacking of Sardis. This led to an Achaemenid campaign against Greece known as the Greco-Persian Wars which lasted the first half of the 5th century BC. During the Greco-Persian wars Persia made some major advantages and razed Athens in 480 BC, But after a string of Greek victories the Persians were forced to withdraw. Fighting ended with the peace of Callias in 449 BC. Persepolis, ceremonial capital of the Persian Empire during the Achaemenid dynasty
The rules and ethics emanating from Zoroaster's teachings were strictly followed by the Achaemenids who introduced and adopted policies based on human rights, equality and banning of slavery. Zoroastrianism spread unimposed during the time of the Achaemenids and through contacts with the exiled Jewish people in Babylon freed by Cyrus, Zoroastrian concepts further propagated and influenced into other Abrahamic religions. The Golden Age of Athens marked by Aristotle, Plato and Socrates also came about during the Achaemenid period while their contacts with Persia and the Near East abounded. The peace, tranquility, security and prosperity that were afforded to the people of the Near East and Southeastern Europe proved to be a rare historical occurrence, an unparalleled period where commerce prospered, and the standard of living for all people of the region improved.[41]
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.

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 GreekSeleucid Empire, beginning in the late 3rd century BC, and intermittently controlled Mesopotamia between ca. 150 BC and 224 AD. These were the third native dynasty of ancient Iran and lasted five centuries. After the conquests of Media, Assyria, Babylonia and Elam, the Parthians had to organize their empire. The former elites of these countries were Greek, and the new rulers had to adapt to their customs if they wanted their rule to last. As a result, the cities retained their ancient rights and civil administrations remained more or less undisturbed.
Parthia was the arch-enemy of the Roman Empire in the east, limiting Rome's expansion beyond Cappadocia (central Anatolia). By using a heavily armed and armoured cataphract cavalry, and lightly armed but highly mobile mounted archers, the Parthians "held their own against Rome for almost 300 years".[42] Rome's acclaimed general Mark Antony led a disastrous campaign against the Parthians in 36 BC in which he lost 32,000 men. By the time of Roman emperor Augustus, Rome and Parthia were settling some of their differences through diplomacy. By this time, Parthia had acquired an assortment of golden eagles, the cherished standards of Rome's legions, captured from Mark Antony, and Crassus, who suffered a defeat at Carrhae in 53 BC.[43]

The end of the Parthian Empire came in 224 AD, when the empire was loosely organized and the last king was defeated by Ardashir I, one of the empire's vassals. Ardashir I then went on to create the Sassanid Empire. Soon he started reforming the country both economically and militarily. The Sassanids established an empire roughly within the frontiers achieved by the Achaemenids, referring to it as Erânshahr or Iranshahr, , "Dominion of the Aryans", (i.e. of Iranians), with their capital at Ctesiphon.[44] 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.[45] During their reign, Sassanid battles with the Roman Empire caused such pessimism in Rome that the historian Cassius Dio wrote:
“
Here was a source of great fear to us. So formidable does the Sassanid king seem to our eastern legions, that some are liable to go over to him, and others are unwilling to fight at all.[46]

After the Islamic conquest of Persia, Iran was annexed into the Arab Umayyad Caliphate. But the Islamization of Iran was to yield deep transformations within the cultural, scientific, and political structure of Iran's society: The blossoming of Persian literature, philosophy, medicine and art became major elements of the newly forming Muslim civilization, culturally, politically, and religiously. The Iranian contribution to this new Islamic civilization caused the Islamic Golden Age.[50] Abu Moslem, an Iranian general, expelled the Umayyads from Damascus and helped the Abbasid caliphs to conquer Baghdad. The Abbasid caliphs frequently chose their "wazirs" (viziers) among Iranians, and Iranian governors acquired a certain amount of local autonomy. Thus in 822, the governor of Khorasan, Tahir, proclaimed his independence and founded a new Persian dynasty of Tahirids. And by the Samanid era, Iran's efforts to regain its independence had been well solidified.[51]
Ayatollah Khamenei, Supreme Leader of Iran
The political system of the Islamic Republic is based on the 1979 Constitution. The system comprises several intricately connected governing bodies. The Supreme Leader of Iran is responsible for delineation and supervision of the general policies of the Islamic Republic of Iran.[75] 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.[75] 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 Council of Guardians are appointed by the Supreme Leader.[75] The Assembly of Experts elects and dismisses the Supreme Leader on the basis of qualifications and popular esteem.[76] 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.[75][77] The President is elected by universal suffrage for a term of four years and can only be re-elected for one term.[77] Presidential candidates must be approved by the Council of Guardians prior to running in order to ensure their allegiance to the ideals of the Islamic revolution.[78] 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.[75] The President appoints and supervises the Council of Ministers, coordinates government decisions, and selects government policies to be placed before the legislature.[79] Eight Vice-Presidents serve under the President, as well as a cabinet of twenty two ministers, who must all be approved by the legislature.[80] 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 elected in a run-off poll in the 2005 presidential elections. His term expires in 2009.[81]
Economy
Main article: Economy of Iran See also: Next Eleven, Central Bank of Iran, Tehran Stock Exchange, Transport in Iran, Communications in Iran, Construction in Iran, Privatization in Iran, Foreign Direct Investment in Iran, and Economic Cooperation Organization 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.[95] Its economic infrastructure has been improving steadily over the past two decades but continues to be affected by inflation and unemployment.[96] 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.[97] Government spending contributed to an average annual inflation rate of 14% in the period 2000–2004. Iran has earned $70 billion in foreign exchange reserves mostly from crude oil exports (80% as of 2007).[98] In 2007, the GDP was estimated at $206 billion ($852 billion at PPP), or $3,160 per capita ($12,300 at PPP).[28] Iran's official annual growth rate was at 6% (2008).[99] Because of these figures and the country’s diversified but small industrial base, the United Nations classifies Iran's economy as semi-developed.[100]
The services sector has seen the greatest long-term growth in terms of its share of GDP, but the sector remains volatile. State investment has boosted agriculture with the liberalization of production and the improvement of packaging and marketing helping to develop new export markets. Thanks to the construction of many dams throughout the country in recent years, large-scale irrigation schemes, and the wider production of export-based agricultural items like dates, flowers, and pistachios, produced the fastest economic growth of any sector in Iran over much of the 1990s. Tehran was one of the first cities in Iran which was modernized in the Pahlavi era
Close to 1.8% of national employment is generated in the tourism sector which is slated to increase to 10% in the next five years.[101] 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.[102] 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.[103] 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.[104][105]
The authorities so as the private sector have put in the past 15 years 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. Today, the government is trying to privatize these industries, and despite some successes, there are still several problems to be overcome such as the lagging corruption in the public sector (and therefore, nationalized industries) and lack of competitiveness.
Globally, Iran has leading manufacture industry in the fields of car-manufacture and transportations, construction materials, home appliances, food and agricultural goods, armaments, pharmaceuticals, information technology, power and petrochemicals.[106]
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 also second in oil reserves.[107] It is OPEC's 2nd largest oil exporter. In 2005, Iran spent $4 billion on fuel imports, because of contraband and inefficient domestic use.[108] 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 2000s, industry infrastructure was increasingly inefficient because of technological lags. Few exploratory wells were drilled in 2005.
In 2004, a large share of Iran’s natural gas reserves were untapped. 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 is set to go online early 2009.[109][110]
Population of Iran Religion in Iran is dominated by the TwelverShi'a branch of Islam, which is the official state religion and to which about 89% of Iranians belong. About 9% 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.[28] 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[citation needed], 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.[116][117] Currently, the Islamic Republic of Iran is noted for significant human rights violations, despite efforts by human right activists, writers, NGOs and some political parties. Human rights violations include governmental impunity, restricted freedom of speech, gender inequality, treatment of homosexuals, execution of minors, and in some cases torture.
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 the last report on health systems ranks Iran's performance on health level 58th, and its overall health system performance 93rd among the world's nations.[118]

The Culture of Iran is a mix of ancient pre-Islamic culture and Islamic culture. Iranian culture probably originated in Central Asia and the Andronovo culture is strongly suggested as the predecessor of Iranian culture ca. 2000 BC. 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,[119] and so influenced as far as Western Europe and Africa.[120] This influence played a prominent role in the formation of both Asiatic and European medieval art.[121] 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.[122][123][124]

After Islamicization 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.[124][125] 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.[126] Nowrouz was nominated as one of UNESCO's Masterpieces of the Oral and Intangible Heritage of Humanity in 2004.[127]
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. 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.[128] Iranian food is not spicy. 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. 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.[129]
The region where Persian (green) and other Iranian languages are spoken
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 large languages of Iran such as Azeri, Kurdish and even in relatively smaller ones such as Arabic and Armenian. Many languages have originated from Iran, but Persian is the most used language. Persian is a tongue belonging to the Aryan or Indo-Iranian branch of the Indo-European family of languages. The oldest records in Old Persian date back to the Achaemenid Empire[130] and examples of Old Persian have been found in present-day Iran, Iraq, Turkey and Egypt. In the late 8th century the Persian language 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.

Attempts of Arabization thus never succeeded in Iran, and movements such as the Shuubiyah became catalysts for Iranians to regain their independence in their relations with the Arab invaders. The cultural revival of the post-Abbasid period led to a resurfacing of Iranian national identity. The resulting cultural movement reached its peak during the 9th and 10th centuries. The most notable effect of the movement was the continuation of the Persian language, the language of the Persians and the official language of Iran to the present day. Ferdowsi, Iran's greatest epic poet, is regarded today as the most important figure in maintaining the Persian language. After an interval of silence Iran re-emerged as a separate, different and distinctive element within Islam. Iranian philosophy after the Islamic conquest, is characterized by different interactions with the Old Iranian philosophy, the Greek philosophy and with the development of Islamic philosophy. The Illumination School and the Transcendent Philosophy are regarded as two of the main philosophical traditions of that era in Persia. The movement continued well into the 11th century, when Mahmud-a Ghaznavi founded a vast empire, with its capital at Isfahan and Ghazna. Their successors, the Seljuks, asserted their domination from the Mediterranean Sea to Central Asia. As with their predecessors, the divan of the empire was in the hands of Iranian viziers, who founded the Nizamiyya. During this period, hundreds of scholars and scientists vastly contributed to technology, science and medicine, later influencing the rise of European science during the Renaissance.[52]
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,[53] turning the streets of Persian cities such as Neishabur into "rivers of blood", as the severed heads of men, women, and children were "neatly stacked into carefully constructed pyramids around which the carcasses of the city's dogs and cats were placed".[54] Between 1220 and 1260, the total population of Iran had dropped from 2,500,000 to 250,000 as a result of mass extermination and famine.[55] In a letter to King Louis IX of France, Holaku, one of the Genghis Khan's grandsons, alone took responsibility for 200,000 deaths in his raids of Iran and the Caliphate.[56] He was followed by yet another conqueror, Tamerlane, who established his capital in Samarkand.[57] The waves of devastation prevented many cities such as Neishabur from reaching their pre-invasion population levels until the 20th century, eight centuries later.[58] 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.[59]
Dizin skiing resort, Iran Main article: Sport in Iran
With two thirds of Iran's population under the age of 25, sports constitutes a highly active portion of Iran's society, both traditional and modern. Iran hence was the birthplace of sports such as polo,[143] and Varzesh-e Pahlavani. Freestyle wrestling has been traditionally referred to as Iran's national sport, but today, the most popular sport in Iran is football (soccer), with the national team having reached the World Cup finals three times, and having won the Asian Cup on three occasions. Iran was the first country in the Middle East to host the Asian Games. It is home to several unique skiing resorts,[144] with the Tochal resort being the world's fifth-highest ski resort (3,730 m/12,238 ft at its highest station) situated only fifteen minutes away from Tehran. Being a mountainous country, Iran offers enthusiasts abundant challenges for hiking, rock climbing,[145] and mountain climbing.[146][147][148] Iranian women are also active in sports.
