Iran is a state occupying the West Asia region and historically, culturally, politically, and economically one of the most important countries in the area. Officially known as the Islamic Republic of Iran, country is one of the most populous countries in Middle East with a population of approximately 89.5 million. With a total area of 1,648,000 km², Iran shares land borders with Afghanistan and Pakistan to the east, Iraq and Türkiye to the west, and Armenia, Azerbaijan and Turkmenistan to the north. It also has coastlines along the Caspian Sea, Basra Gulf and Oman Sea.
Iran has a multicultural structure composed of various ethnic groups. The largest ethnic groups in the country are Persians and Azerbaijani Turks, while Khorasani Turks, Afshars, Halachs, Kurds, Lors, Arabs and Baluchis are also significant ethnic communities. The official language is Persian, but various dialects of Turkish, Kurdish, Arabic and Baluchi are also spoken.
Iranian Rial is the country’s official money unit.
Iran was proclaimed the Islamic Republic of Iran on 1 April 1979. The country’s governance structure is a theocratic system in which the religious leader (Revolution Supreme Leader) holds extensive powers. The President is elected every four years by people, but the highest authority in the country is the Religious Leader Ayatollah Seyyed Ali Khamenei. Execution, legislative and judicial powers operate under the supervision of the Revolutionary Leader. Iran’s current President is Masoud Pezeshkian, and the Minister of Foreign Affairs is Abbas Iraki.
Iran is one of the countries playing a significant role in regional and global politics politically, economically and militarily. Due to its rich oil and natural gas reserves, Iran holds a critical position in global energy markets. However, economic balances remain volatile due to international sanctions, domestic economic challenges and tensions in foreign policy. Iran continues its policy of deepening economic and political ties with China and Russia, while disagreements with the international community over its nuclear program remain a central issue in its foreign policy.
The territory of Iran has been home to various civilizations since the 4th millennium BCE. The earliest state formation process began with the Elamite Civilization, and the Elamites developed a culture relationship with Mesopotamia. After the Elamites, the Medes and Persians came under the control of Indo-Iranian Europe communities.
The Medes gained independence from the Assyrian Empire in the 7th century BCE and became a powerful state under the rule of Cyaxares in 625 BCE. However, Median dominance did not last long; in 550 BCE, the Persians under Cyrus the Great defeated the Medes and founded the Achaemenid Empire.
Cyrus the Great organized the Persians into a strong administration, conquered Babylon and granted rights to the Jews. Under his rule, an empire extending from Mesopotamia to Anatolia, Central Asia and Egypt was established.
The Achaemenids governed the region through the satrapy system and strengthened infrastructure networks such as the Royal Road. During the reign of Darius I (522–486 BCE), the city of Persepolis became the empire’s capital and administration became more institutionalized.
However, in 330 BCE, Alexander the Great defeated the Achaemenids and seized Persian territories. After his death, Iranian lands came under the control of the Seleucid Kingdom.
As the Seleucids weakened, the Parthians, of Scythian origin, took control of Iran. The Arsacid dynasty established a powerful state through sustained rivalry with the Roman Empire. During the reign of Mithridates I (171–138 BCE), the Parthians captured Mesopotamia and became the dominant power in the region.
The Parthians blended Hellenistic culture with Iranian traditions. However, the weakening of central authority led to increased local rebellions, paving the way for the rise of the Sassanian Empire.
Ardashir I defeated the Parthians in 224 CE and established the Sassanian Empire, making Zoroastrianism the state religion. Sassanian rule was in constant war with Rome and Byzantium, and during the reign of Shapur I (241–272 CE), the Sassanians captured the Roman Emperor Valerian in a major power display.
The Sassanian state developed a centralized administrative system, and the Zoroastrian priestly class gained significant political power. During the reign of Khusrau I (531–579 CE), the Sassanian Empire made major advances in science, art and law fields.
However, in the 7th century, the Sassanian army weakened in the face of Arab conquests, and the empire was completely destroyed with the death of the last Sassanian ruler, Yazdegerd III, in 651 CE.
Iran was conquered by Muslim Arabs in 651 and integrated into Islamic culture during the Umayyad (661–750) and Abbasids periods. However, Iran developed a distinct identity within the Islamic world, and Shiism began to spread during this period.
In the 9th and 10th centuries, local dynasties emerged in Iran:
In the 11th century, the Great Seljuk Empire (1040–1194) dominated Iran, and state organization strengthened under Nizam al-Mulk. However, the Crusades and the Mongol invasions weakened the Seljuks.
In 1258, Mongols destroyed the Abbasid Caliphate and brought Iran under the control of the Ilkhanids. Under the leadership of Hülegü Inn, the Mongols inflicted massive destruction in Iran. In the 14th century, the Timurid Empire (1370–1507) conquered Iran, and Timur controlled the region through harsh governance.
In 1501, Shah Ismail founded the Safavids State and declared Shiism the official religion of Iran. The Battle of Chaldiran (1514) with the Ottomans halted Safavid expansion to the west. During the reign of Shah Abbas (1588–1629), the Safavids experienced their golden age, and Isfahan became a major cultural center.
However, in the 18th century, due to Afghan uprisings and internal conflicts, the Safavids weakened and were deposed by Nader Shah (1736–1747).
In 1794, Ağa Muhammad Khan established the Qajar dynasty and restored centralized rule in Iran. However, the They flee period was marked by rivalry between Russia and Britain. In the 19th century, Iran lost territories in Caucasus as a result of wars with the Russians.
In 1925, Reza Shah Pahlavi overthrew the Qajars and initiated modernization reforms. In 1935, the country’s name was officially changed to Iran. In 1951, Prime Minister Mohammad Mosaddegh nationalized the oil industry but was removed from office in 1953 by a Western-backed coup.
In 1979, the Islamic Revolution led by Ayatollah Khomeini established the Islamic Republic of Iran and ended the monarchy. The Iran-Iraq War (1980–1988) inflicted great harm on the country.
Under the leadership of Ali Khamenei (1989–), Iran has maintained a theocratic governance structure. Following the death of Ebrahim Raisi in 2024, Masoud Pezeshkian was elected Iran’s new president. Iran continues to face economic sanctions, regional conflicts and international pressure.
Iran is a country located in Central East and in the southwest of Asia. It lies between 32° north latitude and 53° east longitude. It is bordered by the Persian Gulf and Oman Sea to the south, the Caspian Sea to the north, Iraq and Türkiye to the west, and Afghanistan and Pakistan to the east.
The total area is 1,648,195 km². In terms of area, Iran covers slightly small territory than Alaska.
Iran’s land borders total 5,894 km in length. Border lengths with neighboring countries are as follows:
Iran has a coastline of 2,440 km, which opens onto both the Persian Gulf and Oman Sea as well as the Caspian Sea to the north.
Iran has a mountainous and rugged terrain. Most of the country consists of high plateaus and mountainous areas, while coastal strips are narrow and irregular.
The main geographical regions are:
Iran’s land structure is highly mountainous and rugged. The average elevation is 1,305 m; the lowest point is the Caspian Sea at -28 m, and the highest point is Mount Damavand at 5,625 m.
Desertification and aridity are major challenges in Iran. Two major deserts exist in the eastern and interior regions:
Iran has few major rivers, most of which dry up before reaching the sea. However, some of the most important rivers in the region include:
Major Lakes:
Iran is a country rich in natural resources. The most important resources are:
Iran is predominantly a dry and semi-arid country. However, due to its geographical diversity, climate conditions vary significantly from region to region. There are notable differences in temperature and precipitation between the northern coasts, interior regions, mountainous areas and southern coasts.
Iran’s climate can be divided into four main zones:
Due to its climate, certain natural disasters occur frequently in some regions of Iran:
As of 2024, Iran has a population of 88.38 million. When analyzed by gender, the population consists of 44.79 million males and 43.59 million females. The population growth rate is 0.88%, ranking 104th globally. Iran’s urbanization rate is 77.3%, with an annual urban growth rate of 1.32%.
Iran has a multi-ethnic population structure. Persians and Azerbaijani Turks form the majority, while Turkmen, Khorasani Turks, Afshars, Halachs, Kurds, Lors, Arabs and Baluchis are other significant ethnic groups. The official language is Persian, and Azerbaijani Turkish, Turkmen, Kurdish, Arabic and Baluchi are also spoken.
Iran’s population age structure is as follows:
Iran’s average life expectancy is 75.6 years overall, with 74.3 years for males and 77.1 years for females. The average age is 33.8 years, calculated at 33.6 for males and 34.1 for females.
Iran is an important country for refugees, hosting large refugee populations from Afghanistan and Iraq. As of 2022, there were 750,000 registered Afghan refugees and approximately 500,000 undocumented Afghan migrant in the country. Additionally, 12,000 Iraqi refugees reside in Iran. Iran’s net migration rate is -0.3, indicating it is a country of net emigration.
In Iran, the population is concentrated in the western and northern regions. The location of the Zagros and Alborz Mountains has led to population clustering in the west and northwest, while eastern and central Iran’s desert regions (Deşt-e Kavir and Deşt-e Lut) are sparsely populated.
The country’s largest cities and populations (2023 data):
Iran has a significant social structure characterized by fast urbanization, changing demographic patterns and ethnic diversity. Although the majority of the population is young, declining fertility rates and rising elderly population proportions are expected to cause demographic shifts in the coming years.
Due to its geographic location, energy resources and political structure, Iran is a major actor in international relations. After the 1979 Islamic Revolution, the country experienced serious tensions with the West, particularly severing diplomatic ties with USA. Iran has been subjected to sanctions by the United States and the European Union (EU) over its nuclear activities, links to terrorism and human rights violations.
Iran’s relations with the West reached a breaking point with the 1979 U.S. Embassy Hostage Crisis. Diplomatic relations were severed in 1980, and Iran has been labeled by the U.S. as a “state sponsor of terrorism” since 1984. The 2015 Joint Comprehensive Plan of Action (JCPOA) aimed to limit Iran’s nuclear activities in exchange for easing economic sanctions, but the U.S. withdrawal from the agreement in 2018 and reimposition of sanctions worsened relations. As of 2023, the EU and the United Kingdom have also decided to maintain arms and missile embargoes against Iran.
Iran has adopted a strategy of increasing economic and political cooperation with China and Russia in response to U.S. sanctions. China is Iran’s largest trading partner and holds a significant share of its oil imports. Russia collaborates with Iran in military and nuclear technology fields. Iran cooperates with these two countries in defense, energy and infrastructure projects.
Iran’s regional policy involves complex and often tense relations with neighboring countries.
Iran is a member of various international organizations and participates in regional cooperation, particularly in economic and security fields. Important international organizations of which Iran is a member include:
President Ebrahim Raisi, who took office in 2021, pursued policies to strengthen economic ties with China and Russia in response to U.S. sanctions, and Iran joined the BRICS group. However, protests following the death of Mahsa Amini in 2022 and internal political developments negatively affected Iran’s international image. It remains unclear how foreign policy will evolve following the inauguration of President Masoud Pezeshkian in 2024, as change has not yet yet clarified.
Iran’s military structure is divided into two main components established after the Islamic Revolution: the Islamic Republic of Iran Regular Armed Forces (Artesh) and the Islamic Revolutionary Guard Corps (IRGC – Sepah). Both building operate in different areas of the armed forces and play decisive roles in Iran’s defense strategy.
Artesh serves as Iran’s traditional military and consists of land, air, sea and air defense forces. Its mission is to protect Iran’s borders against external threats.
The Revolutionary Guard Corps was established after the 1979 Islamic Revolution and is a military force directly subordinate to Iran’s religious leader. It is responsible for internal security, ideological protection and external operations.
Iran’s economy has traditionally been state-controlled, but recent years have seen various initiatives to reform financial institutions and industry. The country possesses rich natural resources, primarily oil and natural gas, which form the backbone of its economy. However, international sanctions, exchange rate fluctuations and domestic economic uncertainties affect Iran’s economic growth.
Iran’s economy consists of three main sectors:
Iran’s international trade faces severe restrictions due to economic sanctions. The U.S. withdrawal from the Joint Comprehensive Plan of Action (JCPOA) in 2018 reinstated nuclear-related sanctions on Iran. In 2023, the European Union (EU) and the United Kingdom also continued sanctions due to Iran’s failure to meet its nuclear commitments.
Although Iran runs a trade surplus, it faces severe restrictions on oil exports due to sanctions.
Oil and natural gas exports, Iran’s primary source of income, constitute a large portion of total export revenue. As of 2022, main export items include:
Iran is dependent on imports for industry and consumer goods. As of 2022, the most imported products include:
Iran’s foreign trade partners are limited by sanctions, leading it to focus on Asian and regional countries. As of 2022, Iran’s largest export and import partners are as follows:
Iran is a major actor in the global energy market. The country possesses vast oil and natural gas reserves and uses these resources as the foundation of its industry, exports and state revenues.
Iran’s total labor force is approximately 29.78 million. The unemployment rate in 2023 was calculated at 9.1%.
The Gini coefficient for income distribution is 34.8, indicating moderate income inequality.
Although Iran possesses significant tourism potential due to its rich history, cultural heritage and natural beauty, the tourism sector has not developed meaningfully due to international sanctions, political conditions and infrastructure deficiencies. Throughout history, Iran has hosted numerous great civilizations and possesses many important structures listed on the UNESCO World Heritage List.
Iran has served as the center of the Persian Empire and has preserved important structures from that era. Iran has a total of 28 World Heritage Sites, 26 cultural and 2 natural entity.
These historical structures enhance Iran’s cultural and tourist appeal, but religious and political restrictions limit foreign tourist inflow.
Iran’s geographical diversity encompasses a wide range from mountainous areas to deserts, forests to coastal regions. Natural areas such as the Hyrcanian Forests and Lut Desert in northern Iran are included in the UNESCO World Heritage List.
Iran is considered one of the major religious centers of the Islamic world. Due to its central position in Shiism, it hosts important religious sites for Shia Muslims.
These cities attract visitors primarily from Iran and neighboring countries with large Shia populations.
Iran’s capital, Tehran, reflects the country’s modern face through its modern museums, art galleries and cultural events. Major cities also offer various opportunities for commercial and tourist activities through shopping centers and traditional bazaars.
Several factors hinder the development of tourism in Iran:
Throughout history, Iran has been a meeting point of various civilizations and cultural currents, possessing a rich heritage in art, literature, architecture and traditional crafts. Iran’s Persian culture has developed through Islamic artistic sensibilities and local traditions. Iranian culture has established a unique identity in fields such as literature, music, cinema, architecture and handicrafts.
Iran holds an important place in world literature. Persian literature, especially poetry, has had a major influence, and classical Persian poets are renowned worldwide.
In Iran, poetry and literature have been not only literary fields but also integral parts of social and cultural life.
Iran’s architectural heritage can be examined across a broad spectrum from ancient times to Islamic art. A dominant architectural approach features rich ornamentation, symmetry understanding and prominent religious motifs.
In Iranian architecture, especially under Islamic influence, mosque and madrasa architecture developed, with domes and mosaic decorations becoming prominent features.
Iran possesses a broad cultural heritage in handicrafts. Iranian artisans have produced world-renowned works in carpet weaving, Ceramics, miniature painting and gilding.
These handicrafts continue to be an essential part of Iran’s artistic identity.
Iranian music has a structure that incorporates both traditional and modern elements. Classical Iranian music is based on modal systems, with improvisation and rhythmic structure taking center stage.
Iranian music has been enriched by Shia Sufism music and traditional folk melodies, evolving through classical and modern styles over different periods.
Iranian cinema has achieved significant international success in recent years. Directors such as Abbas Kiarostami, Asghar Farhadi and Majid Majidi have made Iranian cinema internationally renowned.
Iranian cinema stands out through social realism, symbolism and minimalist storytelling techniques.
One of the most important elements defining Iran’s cultural identity is its traditional holidays and festivals. These celebrations incorporate elements from both Islamic and ancient Persian culture.
These celebrations are vital events sustaining Iran’s cultural continuity.
