Iran

Iran (Persian: ایران), officially the Islamic Republic of Iran and historically known in the West as Persia, is a sovereign state in Western Asia. It covers an area of approximately 1,648,195 square kilometres, making it the seventeenth-largest country in the world. Tehran is the capital and largest city. Iran is a founding member of the United Nations, the Non-Aligned Movement, and the Organisation of Islamic Cooperation.

Geography

Iran is bordered to the northwest by Armenia and Azerbaijan, to the north by the Caspian Sea, to the northeast by Turkmenistan, to the east by Afghanistan and Pakistan, to the south by the Persian Gulf and Gulf of Oman, and to the west by Turkey and Iraq. The country's terrain is dominated by rugged mountain ranges, most notably the Alborz range in the north and the Zagros range running diagonally from the northwest to the southeast. The central plateau contains two large deserts: the Dasht-e Kavir (Great Salt Desert) and the Dasht-e Lut. The Alborz range includes Mount Damavand, a dormant volcano standing at approximately 5,610 metres, the highest peak in Iran and in the Middle East.

The climate varies considerably across the country, from subtropical along the Caspian coast in the north to arid and semi-arid in the interior plateau, and hot and humid along the Persian Gulf coast in the south.

History

Ancient and Pre-Islamic Period

Iran is one of the world's oldest inhabited regions, with settlements dating back tens of thousands of years. The Achaemenid Empire, founded by Cyrus the Great in 550 BCE, was the first Persian empire and one of the largest empires of the ancient world, stretching from the Balkans to the Indus Valley. Cyrus is particularly noted for his declaration of religious tolerance and his policy of allowing conquered peoples to maintain their customs, documented in the Cyrus Cylinder, sometimes regarded as an early human rights document, though historians debate its precise interpretation.

The Achaemenid Empire was conquered by Alexander the Great between 334 and 323 BCE. It was subsequently ruled by the Seleucid dynasty before the rise of the Parthian Empire (247 BCE – 224 CE) and then the Sasanian Empire (224–651 CE), which became a major power rivalling the Byzantine Empire.

Islamic Conquest and Medieval Period

The Arab Muslim conquest of Persia between approximately 633 and 654 CE brought an end to the Sasanian Empire and gradually introduced Islam to the region. While the population converted to Islam over the following centuries, Persian language and culture survived and profoundly shaped Islamic civilisation during the Islamic Golden Age. Persia produced major scholars in philosophy, medicine, mathematics, and literature during this period, including Ibn Sina (Avicenna) and the poets Rumi, Hafez, and Ferdowsi.

The Mongol invasions of the thirteenth century, led first by Genghis Khan and later by his successors, caused devastating population loss and destruction across the Iranian plateau. Recovery was gradual, and various dynasties held power before the rise of the Safavid dynasty.

Safavid Dynasty and Early Modern Period

The Safavid dynasty (1501–1736) marked a pivotal moment in Iranian history, as Shah Ismail I declared Twelver Shia Islam the official state religion, shaping Iran's distinct religious identity within the broader Muslim world. The Safavid period saw significant cultural and artistic flourishing, particularly in architecture and miniature painting, with Isfahan serving as the imperial capital.

Subsequent dynasties including the Afsharid, Zand, and Qajar ruled Iran through to the early twentieth century. The Qajar period (1789–1925) was marked by increasing foreign interference from Russia and Britain, territorial losses, and the Constitutional Revolution of 1905–1911, which established a parliament (Majles) and constitutional monarchy.

Pahlavi Dynasty

Reza Shah Pahlavi came to power in 1925, founding the Pahlavi dynasty and initiating extensive modernisation and secularisation programmes. His son, Mohammad Reza Shah Pahlavi, continued these reforms. A significant episode of this era was the 1953 coup d'état, in which the democratically elected Prime Minister Mohammad Mosaddegh was overthrown. Responsibility for the coup has been attributed to British and American intelligence agencies, a fact acknowledged by the CIA in declassified documents released in 2013.

The Shah's rule grew increasingly authoritarian, supported by the secret police organisation SAVAK. Social discontent, economic inequality, and religious opposition led to the Iranian Revolution of 1978–1979.

Islamic Republic

The Iranian Revolution of 1979 resulted in the establishment of the Islamic Republic under Ayatollah Ruhollah Khomeini, who became Supreme Leader. A new constitution established a system of government based on the principle of Velayat-e Faqih (Guardianship of the Islamic Jurist), combining elements of democratic representation with clerical oversight. The revolution was followed almost immediately by the Iran–Iraq War (1980–1988), one of the longest and most destructive conventional wars of the twentieth century.

Since the revolution, Iran has been subject to international sanctions, primarily related to its nuclear programme, which has been a major source of tension with Western nations and Israel. The 2015 Joint Comprehensive Plan of Action (JCPOA) represented a diplomatic agreement between Iran and world powers intended to limit Iran's nuclear activities in exchange for sanctions relief; the United States withdrew from the agreement in 2018 under President Donald Trump, and the situation remained unresolved as of the early 2020s.

Government and Politics

Iran is a theocratic republic. The Supreme Leader holds the highest authority in the state, overseeing the armed forces, the judiciary, and state broadcasting. Ali Khamenei has served as Supreme Leader since 1989. The President serves as head of government and is elected by popular vote, though candidates must be approved by the Guardian Council. The parliament (Majles) is a unicameral legislature whose members are also subject to candidate vetting.

Human rights organisations, including Amnesty International and Human Rights Watch, have consistently documented significant restrictions on freedom of expression, assembly, and the press, as well as concerns regarding the treatment of religious minorities, women, and political dissidents.

Economy

Iran possesses the world's second-largest natural gas reserves and the fourth-largest proven crude oil reserves, making hydrocarbons the backbone of its economy. The country is a member of the Organization of the Petroleum Exporting Countries (OPEC). Prolonged international sanctions have constrained economic development, contributing to high inflation and unemployment, though the precise figures fluctuate and may be disputed.

Beyond hydrocarbons, Iran has significant agricultural production, including pistachios, saffron, and carpets, the last of which represent a notable cultural export. Iran also has a growing industrial base in automotive manufacturing, petrochemicals, and mining.

Culture

Persian culture has exerted enormous influence across a wide region of Asia, particularly through its literature and art. The Persian language (Farsi) is spoken by the majority of the population and serves as a major literary language with a recorded history of over a millennium. Classical Persian poetry, including works by Rumi, Hafez, and Ferdowsi's Shahnameh (Book of Kings), is studied and recited across the Persian-speaking world.

Nowruz, the Persian New Year celebrated at the spring equinox, is a major national holiday with roots predating Islam and is recognised by UNESCO as an Intangible Cultural Heritage. Iranian cinema has achieved international recognition, with directors such as Abbas Kiarostami earning global critical acclaim.

Islam, predominantly the Twelver Shia branch, is the religion of the great majority of the population. Significant religious minorities include Sunni Muslims, Christians, Jews, Zoroastrians, and Bahais, though the Bahai community in particular has faced systematic persecution under the Islamic Republic.
