Prehistory

The earliest attested archaeological artifacts in Iran, like those excavated at Kashafrud and Ganj Par in northern Iran, confirm a human presence in Iran since the Lower Paleolithic. Iran's Neanderthal artifacts from the Middle Paleolithic have been found mainly in the Zagros region, at sites such as Warwasi and Yafteh. From the 10th to the seventh millennium BC, early agricultural communities began to flourish in and around the Zagros region in western Iran, including Chogha Golan, Chogha Bonut, and Chogha Mish.

The occupation of grouped hamlets in the area of Susa, as determined by radiocarbon dating, ranges from 4395–3955 to 3680–3490 BC. There are dozens of prehistoric sites across the Iranian Plateau, pointing to the existence of ancient cultures and urban settlements in the fourth millennium BC.^[1] During the Bronze Age, the territory of present-day Iran was home to several civilizations, including Elam, Jiroft, and Zayanderud. Elam, the most prominent of these civilizations, developed in the southwest alongside those in Mesopotamia, and continued its existence until the emergence of the Iranian empires. The advent of writing in Elam was paralleled to Sumer, and the Elamite cuneiform was developed since the third millennium BC.

From the 34th to the 20th century BC, northwestern Iran was part of the Kura-Araxes culture, which stretched into the neighboring Caucasus and Anatolia. Since the earliest second millennium BC, Assyrians settled in swaths of western Iran and incorporated the region into their territories.

Classical antiquity

By the second millennium BC, the ancient Iranian peoples arrived in what is now Iran from the Eurasian Steppe, rivaling the native settlers of the region. As the Iranians dispersed into the wider area of Greater Iran and beyond, the boundaries of modern-day Iran were dominated by Median, Persian, and Parthian tribes.

From the late 10th to the late seventh century BC, the Iranian peoples, together with the "pre-Iranian" kingdoms, fell under the domination of the Assyrian Empire, based in northern Mesopotamia. Under king Cyaxares, the Medes and Persians entered into an alliance with Babylonian ruler Nabopolassar, as well as the fellow Iranian Scythians and Cimmerians, and together they attacked the Assyrian Empire. The civil war ravaged the Assyrian Empire between 616 and 605 BC, thus freeing their respective peoples from three centuries of Assyrian rule.^[2] The unification of the Median tribes under king Deioces in 728 BC led to the foundation of the Median Empire which, by 612 BC, controlled almost the entire territory of present-day Iran and eastern Anatolia. This marked the end of the Kingdom of Urartu as well, which was subsequently conquered and dissolved.

In 550 BC, Cyrus the Great, the son of Mandane and Cambyses I, took over the Median Empire, and founded the Achaemenid Empire by unifying other city-states. The conquest of Media was a result of what is called the Persian Revolt. The brouhaha was initially triggered by the actions of the Median ruler Astyages, and was quickly spread to other provinces as they allied with the Persians. Later conquests under Cyrus and his successors expanded the empire to include Lydia, Babylon, Egypt, parts of the Balkans and Eastern Europe proper, as well as the lands to the west of the Indus and Oxus rivers.

539 BC was the year in which Persian forces defeated the Babylonian army at Opis, and marked the end of around four centuries of Mesopotamian domination of the region by conquering the Neo-Babylonian Empire. Cyrus entered Babylon and presented himself as a traditional Mesopotamian monarch. Subsequent Achaemenid art and iconography reflect the influence of the new political reality in Mesopotamia.

At its greatest extent, the Achaemenid Empire included territories of modern-day Iran, Republic of Azerbaijan (Arran and Shirvan), Armenia, Georgia, Turkey (Anatolia), much of the Black Sea coastal regions, northeastern Greece and southern Bulgaria (Thrace), northern Greece and North Macedonia (Paeonia and Macedon), Iraq, Syria, Lebanon, Jordan, Israel and the Palestinian territories, all significant population centers of ancient Egypt as far west as Libya, Kuwait, northern Saudi Arabia, parts of the United Arab Emirates and Oman, Pakistan, Afghanistan, and much of Central Asia, making it the largest empire the world had yet seen.^[3]

It is estimated that in 480 BC, 50 million people lived in the Achaemenid Empire. The empire at its peak ruled over 44% of the world's population, the highest such figure for any empire in history.

The Achaemenid Empire is noted for the release of the Jewish exiles in Babylon, building infrastructures such as the Royal Road and the Chapar (postal service), and the use of an official language, Imperial Aramaic, throughout its territories.^[3] The empire had a centralized, bureaucratic administration under the emperor, a large professional army, and civil services, inspiring similar developments in later empires.

Eventual conflict on the western borders began with the Ionian Revolt, which erupted into the Greco-Persian Wars and continued through the first half of the fifth century BC, and ended with the withdrawal of the Achaemenids from all of the territories in the Balkans and Eastern Europe proper.

In 334 BC, Alexander the Great invaded the Achaemenid Empire, defeating the last Achaemenid emperor, Darius III, at the Battle of Issus. Following the premature death of Alexander, Iran came under the control of the Hellenistic Seleucid Empire. In the middle of the second century BC, the Parthian Empire rose to become the main power in Iran, and the century-long geopolitical arch-rivalry between the Romans and the Parthians began, culminating in the Roman–Parthian Wars. The Parthian Empire continued as a feudal monarchy for nearly five centuries, until 224 CE, when it was succeeded by the Sasanian Empire. Together with their neighboring arch-rival, the Roman-Byzantines, they made up the world's two most dominant powers at the time, for over four centuries.^[4][5]

The Sasanians established an empire within the frontiers achieved by the Achaemenids, with their capital at Ctesiphon. Late antiquity is considered one of Iran's most influential periods, as under the Sasanians their influence reached the culture of ancient Rome (and through that as far as Western Europe), Africa, China, and India, and played a prominent role in the formation of the medieval art of both Europe and Asia.

Most of the era of the Sasanian Empire was overshadowed by the Roman–Persian Wars, which raged on the western borders at Anatolia, the Western Caucasus, Mesopotamia, and the Levant, for over 700 years. These wars ultimately exhausted both the Romans and the Sasanians and led to the defeat of both by the Muslim invasion.

Throughout the Achaemenid, Parthian, and Sasanian eras, several offshoots of the Iranian dynasties established eponymous branches in Anatolia and the Caucasus, including the Pontic Kingdom, the Mihranids, and the Arsacid dynasties of Armenia, Iberia (Georgia), and Caucasian Albania (present-day Republic of Azerbaijan and southern Dagestan).

Medieval period

The prolonged Byzantine–Sasanian wars, most importantly the climactic war of 602–628, as well as the social conflict within the Sasanian Empire, opened the way for an Arab invasion of Iran in the seventh century. The empire was initially defeated by the Rashidun Caliphate, which was succeeded by the Umayyad Caliphate, followed by the Abbasid Caliphate. A prolonged and gradual process of state-imposed Islamization followed, which targeted Iran's then Zoroastrian majority and included religious persecution, demolition of libraries and fire temples, a special tax penalty ("jizya"), and language shift.

In 750, the Abbasids overthrew the Umayyads. Arabs Muslims and Persians of all strata made up the rebel army, which was united by the converted Persian Muslim, Abu Muslim. In their struggle for power, the society in their times gradually became cosmopolitan and the old Arab simplicity and aristocratic dignity, bearing and prestige were lost. Persians and Turks began to replace the Arabs in most fields. The fusion of the Arab nobility with the subject races, the practice of polygamy and concubinage, made for a social amalgam wherein loyalties became uncertain and a hierarchy of officials emerged, a bureaucracy at first Persian and later Turkish which decreased Abbasid prestige and power for good.

After two centuries of Arab rule, semi-independent and independent Iranian kingdoms—including the Tahirids, Saffarids, Samanids, and Buyids—began to appear on the fringes of the declining Abbasid Caliphate.

The blossoming literature, philosophy, mathematics, medicine, astronomy and art of Iran became major elements in the formation of a new age for the Iranian civilization, during a period known as the Islamic Golden Age. The Islamic Golden Age reached its peak by the 10th and 11th centuries, during which Iran was the main theater of scientific activities.

The cultural revival that began in the Abbasid period led to a resurfacing of the Iranian national identity; thus, the attempts of Arabization never succeeded in Iran. The Shu'ubiyya movement became a catalyst for Iranians to regain independence in their relations with the Arab invaders. The most notable effect of this movement was the continuation of the Persian language attested to the works of the epic poet Ferdowsi, now considered the most prominent figure in Iranian literature.

The 10th century saw a mass migration of Turkic tribes from Central Asia into the Iranian Plateau. Turkic tribesmen were first used in the Abbasid army as mamluks (slave-warriors), replacing Iranian and Arab elements within the army.^[6] As a result, the Mamluks gained significant political power. In 999, large portions of Iran came briefly under the rule of the Ghaznavids, whose rulers were of mamluk Turkic origin, and longer subsequently under the Seljuk and Khwarezmian empires.^[7] The Seljuks subsequently gave rise to the Sultanate of Rum in Anatolia, while taking their thoroughly Persianized identity with them. The result of the adoption and patronage of Persian culture by Turkish rulers was the development of a distinct Turco-Persian tradition.

From 1219 to 1221, under the Khwarazmian Empire, Iran suffered a devastating invasion by the Mongol Empire army of Genghis Khan. According to Steven R. Ward, "Mongol violence and depredations killed up to three-fourths of the population of the Iranian Plateau, possibly 10 to 15 million people. Some historians have estimated that Iran's population did not again reach its pre-Mongol levels until the mid-20th century." Most modern historians either outright dismiss or are highly skeptical of such statistics of colossal magnitude pertaining the Mongol onslaught on the Khwarazmian empire, mainland Iran and other Muslim regions and deem them to be exaggerations by Muslim chroniclers of that era (whose recordings were naturally of an anti-Mongol bent). Indeed, as far as the Iranian plateau was concerned, the bulk of the Mongol onslaught and battles were in the northeast of what is modern-day Iran, such as in the cities of Nishapur and Tus.

Following the fracture of the Mongol Empire in 1256, Hulagu Khan, grandson of Genghis Khan, established the Ilkhanate in Iran. In 1370, yet another conqueror, Timur, followed the example of Hulagu, establishing the Timurid Empire which lasted for another 156 years. In 1387, Timur ordered the complete massacre of Isfahan, reportedly killing 70,000 citizens. The Ilkhans and the Timurids soon came to adopt the ways and customs of the Iranians, surrounding themselves with a culture that was distinctively Iranian.

Early modern period

Safavids

By the 1500s, Ismail I of Ardabil established the Safavid Empire, with his capital at Tabriz.^[7] Beginning with Azerbaijan, he subsequently extended his authority over all of the Iranian territories, and established an intermittent Iranian hegemony over the vast relative regions, reasserting the Iranian identity within large parts of Greater Iran. Iran was predominantly Sunni, but Ismail instigated a forced conversion to the Shia branch of Islam, spreading throughout the Safavid territories in the Caucasus, Iran, Anatolia, and Mesopotamia. As a result, modern-day Iran is the only official Shia nation of the world, with it holding an absolute majority in Iran and the Republic of Azerbaijan, having there the first and the second highest number of Shia inhabitants by population percentage in the world. Meanwhile, the centuries-long geopolitical and ideological rivalry between Safavid Iran and the neighboring Ottoman Empire led to numerous Ottoman–Iranian wars.^[8]

The Safavid era peaked in the reign of Abbas I (1587–1629),^[8] surpassing their Turkish archrivals in strength, and making Iran a leading science and art hub in western Eurasia. The Safavid era saw the start of mass integration from Caucasian populations into new layers of the society of Iran, as well as mass resettlement of them within the heartlands of Iran, playing a pivotal role in the history of Iran for centuries onwards. Following a gradual decline in the late 1600s and the early 1700s, which was caused by internal conflicts, the continuous wars with the Ottomans, and the foreign interference (most notably the Russian interference), the Safavid rule was ended by the Pashtun rebels who besieged Isfahan and defeated Sultan Husayn in 1722.

Afsharids

In 1729, Nader Shah, a chieftain and military genius from Khorasan, successfully drove out and conquered the Pashtun invaders. He subsequently took back the annexed Caucasian territories which were divided among the Ottoman and Russian authorities by the ongoing chaos in Iran. During the reign of Nader Shah, Iran reached its greatest extent since the Sasanian Empire, reestablishing the Iranian hegemony all over the Caucasus, as well as other major parts of the west and central Asia, and briefly possessing what was arguably the most powerful empire at the time.^[9]

Nader Shah invaded India and sacked far off Delhi by the late 1730s. His territorial expansion, as well as his military successes, went into a decline following the final campaigns in the Northern Caucasus against then revolting Lezgins. The assassination of Nader Shah sparked a brief period of civil war and turmoil, after which Karim Khan of the Zand dynasty came to power in 1750, bringing a period of relative peace and prosperity.^[8]

Zands

Compared to its preceding dynasties, the geopolitical reach of the Zand dynasty was limited. Many of the Iranian territories in the Caucasus gained de facto autonomy and were locally ruled through various Caucasian khanates. However, despite the self-ruling, they all remained subjects and vassals to the Zand king. Another civil war ensued after the death of Karim Khan in 1779, out of which Agha Mohammad Khan emerged, founding the Qajar dynasty in 1794.

Qajars

In 1795, following the disobedience of the Georgian subjects and their alliance with the Russians, the Qajars captured Tbilisi by the Battle of Krtsanisi, and drove the Russians out of the entire Caucasus, reestablishing the Iranian suzerainty over the region.

The Russo-Iranian wars of 1804–1813 and 1826–1828 resulted in large irrevocable territorial losses for Iran in the Caucasus, comprising all of the South Caucasus and Dagestan, which made part of the very concept of Iran for centuries, and thus substantial gains for the neighboring Russian Empire.

As a result of the 19th-century Russo-Iranian wars, the Russians took over the Caucasus, and Iran irrevocably lost control over its integral territories in the region (comprising modern-day Dagestan, Georgia, Armenia, and Republic of Azerbaijan), which got confirmed per the treaties of Gulistan and Turkmenchay.^[10] The area to the north of Aras River, among which the contemporary Republic of Azerbaijan, eastern Georgia, Dagestan, and Armenia are located, were Iranian territory until they were occupied by Russia in the course of the 19th century.^[10]

As Iran shrank, many South Caucasian and North Caucasian Muslims moved towards Iran, especially until the aftermath of the Circassian Genocide,^[11] and the decades afterwards, while Iran's Armenians were encouraged to settle in the newly incorporated Russian territories, causing significant demographic shifts.

Around 1.5 million people—20 to 25% of the population of Iran—died as a result of the Great Famine of 1870–1872.

Between 1872 and 1905, a series of protests took place in response to the sale of concessions to foreigners by Qajar monarchs Naser-ed-Din and Mozaffar-ed-Din, and led to the Constitutional Revolution in 1905. The first Iranian constitution and the first national parliament of Iran were founded in 1906, through the ongoing revolution. The Constitution included the official recognition of Iran's three religious minorities, namely Christians, Jews, and Zoroastrians, which has remained a basis in the legislation of Iran since then. The struggle related to the constitutional movement was followed by the Triumph of Tehran in 1909, when Mohammad Ali Shah was defeated and forced to abdicate. On the pretext of restoring order, the Russians occupied northern Iran in 1911 and maintained a military presence in the region for years to come. But this did not put an end to the civil uprisings and was soon followed by Mirza Kuchik Khan's Jungle Movement against both the Qajar monarchy and foreign invaders.

Despite Iran's neutrality during World War I, the Ottoman, Russian and British empires occupied the territory of western Iran and fought the Persian Campaign before fully withdrawing their forces in 1921. At least 2 million Persian civilians died either directly in the fighting, the Ottoman perpetrated anti-Christian genocides or the war-induced famine of 1917–1919. A large number of Iranian Assyrian and Iranian Armenian Christians, as well as those Muslims who tried to protect them, were victims of mass murders committed by the invading Ottoman troops, notably in and around Khoy, Maku, Salmas, and Urmia.

Apart from the rule of Agha Mohammad Khan, the Qajar rule is characterized as a century of misrule.^[7] The inability of Qajar Iran's government to maintain the country's sovereignty during and immediately after World War I led to the British directed 1921 Persian coup d'état and Reza Shah's establishment of the Pahlavi dynasty. Reza Shah, became the new Prime Minister of Iran and was declared the new monarch in 1925.

Pahlavis

In the midst of World War II, in June 1941, Nazi Germany broke the Molotov–Ribbentrop Pact and invaded the Soviet Union, Iran's northern neighbor. The Soviets quickly allied themselves with the Allied countries and in July and August 1941 the British demanded that the Iranian government expel all Germans from Iran. Reza Shah refused to expel the Germans and on 25 August 1941, the British and Soviets launched a surprise invasion and Reza Shah's government quickly surrendered. The invasion's strategic purpose was to secure a supply line to the USSR (later named the Persian Corridor), secure the oil fields and Abadan Refinery (of the UK-owned Anglo-Iranian Oil Company), prevent a German advance via Turkey or the USSR on Baku's oil fields, and limit German influence in Iran. Following the invasion, on 16 September 1941 Reza Shah abdicated and was replaced by Mohammad Reza Pahlavi, his 21-year-old son.

During the rest of World War II, Iran became a major conduit for British and American aid to the Soviet Union and an avenue through which over 120,000 Polish refugees and Polish Armed Forces fled the Axis advance. At the 1943 Tehran Conference, the Allied "Big Three"—Joseph Stalin, Franklin D. Roosevelt, and Winston Churchill—issued the Tehran Declaration to guarantee the post-war independence and boundaries of Iran. However, at the end of the war, Soviet troops remained in Iran and established two puppet states in north-western Iran, namely the People's Government of Azerbaijan and the Republic of Mahabad. This led to the Iran crisis of 1946, one of the first confrontations of the Cold War, which ended after oil concessions were promised to the USSR and Soviet forces withdrew from Iran proper in May 1946. The two puppet states were soon overthrown, and the oil concessions were later revoked.

1951–1978: Mosaddegh, Mohammad Reza Pahlavi

In 1951, Mohammad Mosaddegh was appointed as the Prime Minister of Pahlavi Iran. After the nationalization of Iran's oil industry, he became enormously popular. He was deposed in the 1953 Iranian coup d'état, an Anglo-American covert operation that marked the first time the United States had participated in an overthrow of a foreign government during the Cold War.

After the coup, the Shah became increasingly autocratic and sultanistic, and Iran entered a decades-long phase of controversially close relations with the United States and some other foreign governments. While the Shah increasingly modernized Iran and claimed to retain it as a fully secular state,^[12] arbitrary arrests and torture by his secret police, the SAVAK, were used for crushing all forms of political opposition.

Ruhollah Khomeini, a radical Muslim cleric, became an active critic of the Shah's far-reaching series of reforms known as the White Revolution. Khomeini publicly denounced the government, and was arrested and imprisoned for 18 months. After his release in 1964, he refused to apologize and was eventually sent into exile.

Due to the 1973 spike in oil prices, the economy of Iran was flooded with foreign currency, which caused inflation. By 1974, the economy of Iran was experiencing a double-digit inflation rate, and despite the many large projects to modernize the country, corruption was rampant and caused large amounts of waste. By 1975 and 1976, an economic recession led to an increased unemployment rate, especially among millions of youths who had migrated to the cities of Iran looking for construction jobs during the boom years of the early 1970s. By the late 1970s, many of these people opposed the Shah's regime and began organizing and joining the protests against it.

After the 1979 Iranian Revolution

The 1979 Revolution, later known as the Islamic Revolution, began in January 1978 with the first major demonstrations against the Shah. After a year of strikes and demonstrations paralyzing the country and its economy, Mohammad Reza Pahlavi fled to the United States, and Ruhollah Khomeini returned from exile to Tehran in February 1979, forming a new government. After holding a referendum, Iran officially became an Islamic republic in April 1979. A second referendum in December 1979 approved a theocratic constitution.

The immediate nationwide uprisings against the new government began with the 1979 Kurdish rebellion and the Khuzestan uprisings, along with the uprisings in Sistan and Baluchestan and other areas. Over the next several years, these uprisings were subdued violently by the new Islamic government. The new government began purging itself of the non-Islamist political opposition, as well as of those Islamists who were not considered radical enough. Although both nationalists and Marxists had initially joined with Islamists to overthrow the Shah, tens of thousands were executed by the new regime afterward. Following Khomeini's order to purge the new government of any remaining officials still loyal to the exiled Shah, many former ministers and officials in the Shah's government, including former prime minister Amir-Abbas Hoveyda, were executed.

On 4 November 1979, after the United States refusal for the extradition of Mohammad Reza Pahlavi to the new government, a group of Muslim students seized the United States Embassy and took the embassy with 52 personnel and citizens hostage . Attempts by the Jimmy Carter administration to negotiate for the release of the hostages, and a failed rescue attempt, helped with the falling popularity of Carter among the US citizens and it pushed him out of the presidential office and brought Ronald Reagan to power. On Jimmy Carter's final day in office, the last hostages were finally set free due to the Algiers Accords. Mohammad Reza Pahlavi left the United States for Egypt, where he died of complications from cancer only months later, on 27 July 1980.

The Cultural Revolution began in 1980, with an initial closure of universities for three years, in order to perform an inspection and clean up in the cultural policy of the education and training system.

On 22 September 1980, the Iraqi army , initiating the Iran–Iraq War. Although the forces of Saddam Hussein made several early advances, by mid-1982, the Iranian forces successfully managed to into Iraq. In July 1982, with Iraq thrown on the defensive, the regime of Iran decided to invade Iraq and conducted countless offensives to conquer Iraqi territory and capture cities, such as Basra. The war continued until 1988 when the Iraqi army defeated the Iranian forces inside Iraq and pushed the remaining Iranian troops back across the border. Subsequently, Khomeini accepted a truce mediated by the United Nations. The total Iranian casualties in the war were estimated to be 123,220–160,000 KIA, 60,711 MIA, and 11,000–16,000 civilians killed.

Following the Iran–Iraq War, in 1989, Akbar Hashemi Rafsanjani and his administration concentrated on a pragmatic pro-business policy of rebuilding and strengthening the economy without making any dramatic break with the ideology of the revolution. In 1997, Rafsanjani was succeeded by moderate reformist Mohammad Khatami, whose government attempted, unsuccessfully, to make the country more free and democratic.

The 2005 presidential election brought conservative populist candidate, Mahmoud Ahmadinejad, to power. By the time of the 2009 Iranian presidential election, the Interior Ministry announced incumbent President Ahmadinejad had won 62.63% of the vote, while Mir-Hossein Mousavi had come in second place with 33.75%. The election results were widely disputed, and resulted in widespread protests, both within Iran and in major cities outside the country, and the creation of the Iranian Green Movement.

Hassan Rouhani was elected as the president on 15 June 2013, defeating Mohammad Bagher Ghalibaf and four other candidates. The electoral victory of Rouhani relatively improved the relations of Iran with other countries.

The 2017–18 Iranian protests swept across the country against the government and its longtime Supreme Leader in response to the economic and political situation. The scale of protests throughout the country and the number of people participating were significant, and it was formally confirmed that thousands of protesters were arrested. The 2019–20 Iranian protests started on 15 November in Ahvaz, spreading across the country within hours, after the government announced increases in the fuel price of up to 300%. A week-long total Internet shutdown throughout the country marked one of the most severe Internet blackouts in any country, and in the bloodiest governmental crackdown of the protestors in the history of Islamic Republic, tens of thousands were arrested and hundreds were killed within a few days according to multiple international observers, including Amnesty International.

On 3 January 2020, the revolutionary guard's general, Qasem Soleimani, was assassinated by the United States in Iraq, which considerably heightened the existing tensions between the two countries. Three days after, Iran's Islamic Revolutionary Guard Corps launched a retaliatory attack on US forces in Iraq and by accident shot down Ukraine International Airlines Flight 752, killing 176 civilians and leading to nation-wide protests. An international investigation led to the government admitting to the shootdown of the plane by a surface-to-air missile after three days of denial, calling it a "human error".
