HISTORY136 - Iran Part 1: Thousands of Years of Dynastic Rule

 It seems like Iran has been in the news for years with constant provocations and chants of “Death to America.”  At the time of this writing, the United States and Israel are pulverizing the leadership and military infrastructure of Iran with continuous airborne assaults.  It might be useful to review the impressive history of Iran before …

 

I’m going to divide this story into two parts.  In this blog (Part 1), after an introduction, I will discuss the prehistory of Iran, and then its key ruling dynasties, up to the year 1979 when Iran became a republic.  In Part 2, I will discuss the history of Iran as a republic, from 1979 to the present, leading up to the current military crisis.

At the end of both parts, I will list my principal sources.

 

Introduction     

Iran, historically known as Persia, is a major Middle Eastern nation, and is home to one of the world's oldest continuous major civilizations, dating back to the 5^th millennium BC.  Today Iran is known for significant oil and gas resources; a unique Islamic Republic government, where a Supreme (religious) Leader holds ultimate authority; and an aggressive foreign policy that counters U.S., Israeli, and Saudi influence in the Middle East.

Iran is situated in Western Asia, with the Caspian Sea to the north and the Persian Gulf/Gulf of Oman to the south.  It shares borders with seven countries: Iraq, Turkey, Armenia, Azerbaijan, Turkmenistan, Afghanistan, and Pakistan. 

Iran is a major Middle Eastern nation.

Iran covers 636,372 square miles, making it the 17^th largest country in the world.  It is roughly one-sixth the size of the entire United States.  The nation has a population of about 93 million, coincidentally making it the 17^th most populous country in the world.  Tehran is the capital and largest city, followed by major urban centers like Isfahan, Shiraz, Tabriz, and Mashhad.  The terrain is characterized by high mountainous and arid landscapes, with the Zagros and Elburz Mountain ranges surrounding central deserts.  Despite holding the world's second-largest gas and third-largest oil reserves, Iran's economy is currently in a state of "chronic crisis" and "near-total erosion" of its middle class due to years of international isolation and internal mismanagement.

Modern Iran’s persistent efforts to develop nuclear weapons, and its role as the world's leading state sponsor of terrorism, have brought it into several recent military conflicts with the U.S. and Israel, including the current (at the time of this writing) ongoing war.

 

Prehistory

The prehistory of Iran spans from the first human ancestor arrival approximately one million years ago; to the emergence of modern humans, homo sapiens, between 70,000 and 45,000 years ago; to the first written records in the 8^th century BC.  Located on the Iranian Plateau, this region was a critical crossroads for early human migrations and one of the world's primary cradles for the development of agriculture, urbanization, and early writing. 

The prehistory of the region is typically categorized into the following stages based on archaeological evidence:

Paleolithic (c. 3,300,000 - 10,000 BC):

·         The earliest evidence of human ancestors includes stone tools found at sites like Kashafrud (northeastern Iran) and Ganj Par (northern Iran) dating back roughly 800,000 to one million years.

·         Evidence of Neanderthal occupation (300,000 - 40,000 BC, particularly in the Zagros Mountains, e.g., Bisitun Cave (70,000 - 40,000 BC) in western Iran. 

·         There is evidence of the emergence of Homo sapiens and more sophisticated blade-tool applications in the Baradostian (c. 36,000 - 18,000 BC) and Zarzian (c. 18,000 - 10,000 BC) cultures in the Zagros Mountains.

Neolithic (c. 10,000 - 6,000 BC):

·         Iran was a key part of the Fertile Crescent.  Early agricultural communities like Chogha Golan (c. 10,000 BC) in the foothills of the Zagros Mountains in western Iran, were among the first to domesticate goats, sheep, and cereal crops.

·         The world’s oldest known clay vessels and figurines were produced at Ganj Dareh (c. 8,200 – 7,600 BC) in the central Zagros Mountains of western Iran.  There was also evidence of the beginnings of settled agricultural life.

 

The Fertile Crescent is a, C-shaped "cradle of civilization" in the Middle East, spanning modern-day Iraq, Syria, Lebanon, Israel, Palestine, Jordan, and parts of Turkey and Iran.  This region's fertile soil - nurtured by the Tigris, Euphrates, and Nile rivers - enabled the birth of agriculture and urbanization around 10,000–8,000 BC.

Chalcolithic & Bronze Age (c. 5,500 - 1,200 BC):

·         Susa, founded around 4395 BC, became one of the world's oldest continuously inhabited cities.

·         Emerging in southwestern Iran, the Elamites developed their own symbolic script by 3200 BC, which is considered the oldest writing system in Iran.

·         Recent excavations in southeastern Iran revealed a sophisticated urban Jiroft culture from the 4^th millennium BC with unique clay carvings and ancient inscriptions.

Iron Age (c. 1,500 - 800 BC):

·         This period marks the transition from prehistory to recorded history as Indo-European tribes - the Medes and Persians - migrated into the plateau from the Pontic-Caspian steppe, directly north of modern-day Iran.

·         The arrival of these groups eventually led to the rise of the Median and later Achaemenid Empires, bringing Iran into the "light of written history.”

 

Key Eras and Dynasties

Iran (formerly Persia) has a thousands-of-years-old history of major Persian civilizations, beginning with the Persian Achaemenid Empire in 550 BC.  Following centuries of rule by various dynasties, the 1979 Islamic Revolution transformed Iran into a theocratic republic led by a Supreme Leader. 

Achaemenid Empire (550 - 330 BC):  The Achaemenid Empire, was the world's first global superpower and the largest empire of its time.  Founded by Cyrus the Great, who defeated earlier short-lived Assyrian empires, it stretched at its peak from the Balkans and Egypt in the west to the Indus Valley in the east.

The Persian Achaemenid Empire in 500 BC was the largest of its time.

The ruling dynasty, the Achaemenids, pioneered a highly efficient centralized bureaucracy using provinces governed by provincial governors.  The empire was linked by the 1,700-mile Royal Road, a massive highway system, and one of the world's first organized postal services.  While the empire was the birthplace of Zoroastrianism (the world’s first monotheistic religion), Cyrus practiced a policy of religious tolerance. 

Zoroastrianism was founded by the Prophet Zoroaster in ancient Persia around 1500 - 1000 BC.  It centers on worshipping the supreme god, Ahura Mazda, and upholding the cosmic order of truth through good thoughts, words, and deeds. 

The Achaemenid Empire is celebrated for its synthesis of diverse cultural influences, creating a unique Persian style that emphasized religious tolerance, grand architecture, and administrative innovation. The ceremonial capital, Persepolis, in southwestern Iran featured the Apadana Hall, famous for its "Treasure Reliefs" and 36 massive fluted columns.  Palaces in Susa featured vibrant, multi-colored glazed bricks depicting "The Immortals" (elite guards), lions, and griffins.  To manage their vast territory, the Achaemenids adopted Aramaic as the official administrative language because its 22-letter alphabet was easier to learn than cuneiform.  They perfected underground irrigation tunnels that transported water over long distances with minimal evaporation.  The empire is credited with early versions of backgammon, the precursor to the guitar, and the tradition of serving dessert after a meal.  Their advanced metal working was featured in gold and silver jewelry, figurines, coins, and ornate ceremonial drinking vessels, often shaped like animals (lions or griffins). 

The empire began a steady decline following failed invasions of Greece and internal court intrigues.  It was eventually conquered by Alexander the Great in 330 BC.

Seleucid Empire (312 - 248 BC): Alexander's empire broke up shortly after his death in 323 BC, and one of Alexander's generals, Seleucus I Nicator, took control of Iran, Mesopotamia, and later Syria and Anatolia. His empire was the Seleucid Empire, a massive Greek state that ruled over West Asia for nearly 250 years during the Hellenistic period.  The Seleucids established hundreds of Greek-style cities, encouraging immigration from Greece to form a dominant ruling elite. 

The Seleucid Empire was a major center of Hellenistic culture, fusing Greek, Mesopotamian, and Persian traditions across the Near East - resulting in distinctive sculptures, ceramics, and metalwork.  Key achievements included establishing major cities like Antioch and Seleucia-on-the-Tigris; promoting Greek theater, arts, and science; and creating the first continuous, year-numbered calendar.  The empire also established a standardized coinage system that remained in circulation for centuries, facilitating profound East-West trade that connected Mediterranean commerce to India.  Babylonian astronomy and mathematics were integrated with Greek knowledge, producing scientific advancements that data than later influenced theories of how the universe works.

By the mid-2^nd century BC, the Parthian Empire had conquered Seleucid Empire, including the Iranian plateau and Mesopotamia, capturing Seleucia, the capital of the Seleucid Empire, in 141 BC.

Parthian Empire (248 BC - 224 AD): The Parthian Empire, also known as the Arsacid Empire, was a major Iranian political and cultural power that became the primary rival to the Roman Empire for nearly five centuries.  The empire was founded by Arsaces I, leader of the Parni, a nomadic Central Asian tribe.  After conquering Parthia in northeastern Iran from the weakening Seleucid Empire, the Arsacids expanded their territory to include the Iranian plateau and Mesopotamia.  By controlling the “Silk Road,” the Parthians became immensely wealthy through trade between Han China and the Roman world.  The empire was a multicultural "melting pot" that blended Persian, Hellenistic (Greek), and Central Asian traditions.  While they adopted Greek as an official language for a time, they eventually saw a strong revival of Iranian culture and Zoroastrianism. The government was a highly decentralized feudal monarchy where local kings and powerful landowning nobles held significant influence. 

The Parthian Empire achieved a unique cultural synthesis, blending Iranian traditions with Hellenistic influences, establishing significant architectural and artistic styles. Major achievements include heavy cavalry innovation and widespread religious tolerance, primarily upholding Zoroastrianism.  Parthian art featured a distinct style characterized by "frontality," where figures face forward to directly engage the viewer.  This included intricate stone reliefs, metalwork, terracotta figurines, and the use of decorated stucco with geometric/floral patterns on interior walls.  Parthian architecture combined Greek elements (pillars, columns) with Iranian concepts, such as massive domes and, notably, a rectangular hall opening to a courtyard.  Key sites included the royal city of Mithradatkert (Nisa) and Ctesiphon, which housed a massive palace and dome.  Evidence suggests a culture of music and dance, with stringed instruments like the sambuca used at court feasts.

The empire eventually weakened due to frequent civil wars, dynastic struggles, and repeated Roman invasions that sacked the capital in 224 AD. 

Sasanian Empire (224 - 651 AD):  The Sasanian Empire, officially known as the Empire of the Iranians, was the last pre-Islamic Persian empire and a global superpower.  Founded by Ardashir I of the house of Sasan, after he overthrew the Parthian Empire, it restored centralized Persian rule and reached its cultural and military zenith as the primary rival to the Roman and later Byzantine Empires.  Shapur II, the longest-reigning monarch, expanded the empire to its greatest height at that time.  Known as the Immortal Soul, he implemented vast tax and military reforms and patronized the Academy of Gundeshapur, a world-renowned center of learning.

The Sasanian Empire achieved a renaissance of Persian culture.  Sasanian art was known for its grand proportions, including palaces with brick vaults and domes, and elaborate rock reliefs.  Sasanian artisans were renowned for silver vessels, particularly high-footed bowls, ewers, and plates featuring intricate hunting scenes or depictions of nobility.  Zoroastrianism was the state religion, with the clergy holding influence.  The era was marked by religious scholarship and the standardization of sacred texts.  Sasanian artistic motifs - such as winged horses and stylized plants - and architectural techniques, including pointed arches, heavily influenced later Islamic art and architecture.  Despite wars, there was a dynamic cultural exchange with the Byzantine Empire, and Sasanian styles influenced luxury goods as far away as China.

Devastating wars with the Byzantines and internal civil strife left the empire vulnerable to the Arab Muslim conquests. 

The Sasanian Empire was the primary rival to the Roman Empire and later Byzantine Empire.

The religion of Islam was founded around 610 AD by the prophet Muhammad, a merchant from the city of Mecca, now in modern-day Saudi Arabia, on the Arabian Peninsula.  Islam is based on the Quran as the literal word of God.  It emphasizes submission to God, strict monotheism, and the Five Pillars: faith, prayer, charity, fasting, and pilgrimage.  After Muhammad’s death in 632 AD, there was an almost immediate split between Sunni Muslims, who believe that their Muslim successor leaders should be elected by the community, and Shia Muslims, who believe that leadership should remain within the Prophet’s bloodline. 

Arab Conquest and Transition to Islam (7^th Century - start of 16^th Century):  From 633 - 651 AD, a pivotal series of Arab military conquest campaigns led to the collapse of the Sasanian Empire and the eventual Islamization of Iran.  From 651 - 1501 AD, Iran transitioned from the Sasanian Empire, with an official state religion of Zoroastrarianism, to an Islamic society under various dynasties, most practicing Shia Islam.  Key eras included Arab caliphates, followed by Persian revival dynasties, and the destructive Mongol conquests (1219 - 1335 AD).   In the 14^th - 15^th centuries, Iran was fragmented under various successors.  This period was marked by gradual Islamization, the preservation of the Persian language, and a cultural renaissance leading up to the Safavid unification in 1501.

Safavid Dynasty (1501 - 1736): The Safavid Dynasty (named after a prominent mystic) was a seminal Iranian empire that unified the region's diverse provinces (albeit with a much smaller extent than the Sasanian Empire) under a single sovereign, and established Shia Islam as the state religion.  It is often regarded as the beginning of modern Iranian history.  Ismail I founded the dynasty in 1501 after capturing Tabriz, Iran’s historic capital. The most enduring Safavid legacy was the mandatory conversion of Iran's predominantly Sunni population to Shia Islam.  This shift gave Iran a unique national identity distinct from its Sunni neighbors.

Today, Sunni Muslims constitute the largest branch of Islam, making up 85-90% of the world's 1.8 billion Muslims.  Sunni Muslims form the majority in almost all Muslim-majority countries, including Indonesia, Pakistan, Bangladesh, Egypt, and Turkey.  Iran, Iraq, Azerbaijan, and Bahrain are the only countries with Shia majorities. 

Under Shah Abbas I (r. 1588–1629), the Safavid Dynasty saw a high point for Persian arts, including calligraphy; refined miniature painting, featuring intricate, detailed scenes within manuscripts; ceramics, influenced by Chinese blue-and-white porcelain; and architectural marvels like the Shah Mosque and Naqsh-e Jahan Square in Isfahan.  Safavid Persia became famous for producing luxurious textiles and rugs, notably silk carpets with complex floral and figured designs, highly prized internationally and marked a peak in Persian artistic craftsmanship.  The state-sponsored promotion of Shia Islam led to the construction of numerous mosques and religious schools, strengthening the cultural identity of Iran.  The period saw a significant continuation of the Persian literary tradition, with poets and scholars flourishing under royal patronage.  Shah Abbas I moved the capital to Isfahan, which became one of the world's most magnificent cities as a hub of art, literature, and philosophy and iconic structures. 

The dynasty began a slow disintegration after the death of Abbas I, due to weak leadership, internal corruption, and constant warfare with the Ottomans and Uzbeks.  In 1722, Afghan rebels captured Isfahan, effectively ending Safavid rule.

The Safavid Empire was bordered by the contentious Ottomans and Uzbeks.

Qajar Dynasty (1789 - 1925): The Qajar dynasty was a royal Iranian dynasty of Turkic origin that reunified Iran after a period of fragmentation, and ruled until the rise of the Pahlavi dynasty.  Founded by Agha Mohammad Khan Qajar, the era was defined by a transition toward modernity, though it was often marred by significant territorial losses and heavy foreign influence from Russia and Great Britain.  Tehran was established as the capital.  The dynasty was known for a cultural and artistic revival, but also for losing vast northern territories (modern-day Georgia and Armenia) to Russia through treaties.  The dynasty introduced Western technology and science but faced public backlash for granting Tobacco Concessions to the British. The era saw the first modern schools, railroads, and the emergence of the Constitutional Revolution of 1906, which established Iran's first parliament and a constitution.  

The Qajar Dynasty saw a vibrant cultural renaissance, blending traditional Persian art with European influences.  A distinct, life-size oil painting style flourished, characterized by European techniques and traditional Persian aesthetics, often showcasing kings in poses of power.  Extensive construction of palaces, mosques, and public buildings occurred in Tehran, including the use of vibrant, detailed tile work.  Introduced in the mid-19^th century, photography flourished, with Naser al-Din Shah being a noted enthusiast and early photographer.  Persian carpet weaving and pottery gained international fame.  The period saw a literary revival, with a focus on both classical forms and the emergence of more politically-oriented, modern writings.  These developments were driven by a desire for modernization while retaining the cultural greatness of Iran, making the Qajar period a vital link between the pre-modern and modern eras. 

During World War I, Iran officially declared neutrality, but was immediately occupied and used as a battlefield by Russian, British, and Ottoman forces.  Despite its neutral status, the country suffered catastrophic casualties, with famine and disease, compounded by troop looting, causing an estimated 2 million deaths.

The final ruler of the Qajar Dynasty, Ahmad Shah Qajar, was deposed by Reza Shah Pahlavi in 1925, following a period of extreme political instability and foreign occupation.

While Iran is one of the world's oldest continuous civilizations, its territorial reach has fluctuated significantly over millennia. The current borders were formalized through a series of 19^th-century treaties following territorial losses to the Russian and British Empires.

Pahlavi Dynasty (1925 - 1979): The Pahlavi dynasty was the final ruling house of the Iranian monarchy before it was replaced by an Islamic republic.  Founded by a military officer, Reza Shah Pahlavi (r. 1925-1941), the dynasty oversaw a period of rapid Western-style modernization and secularization. He is credited with reunifying Iran and initiating industrialization, infrastructure projects (like the Trans-Iranian Railway), and secular reforms, including the 1936 ban on Islamic veils.  In 1935, he officially renamed the country from Persia to Iran. 

Modern oil development in Iran had begun in 1908 during the Qajar Dynasty, with the first commercial discovery at Masjed Soleyman in southwest Iran.  The Anglo-Persian Oil Company (later the Anglo-Iranian Oil Company) started large-scale production in 1914 under a profit-sharing agreement with Great Britain, which was renegotiated in 1933 during the Pahlavi Dynasty. Between 1914-1941 oil production grew rapidly.

During WWII, despite declaring neutrality, Iran was strategically occupied by British and Soviet forces to secure oil fields and supply lines to the USSR.  Reza Shah Pahlavi was forced to abdicate by Allied forces in 1941 due to his perceived ties to Nazi Germany.  Reza Shah Pahlavi’s successor, Mohammad Reza Pahlavi (r. 1941-1979) was the son of Reza Shah.

In 1951, believing that the 1933 oil agreement with Great Britain had failed to satisfy Iranian nationalist demands for full control over its resources, Iran's democratically elected Prime Minister, Mohammad Mosaddegh, nationalized the Anglo-Iranian Oil Company, which had been under British control.  Britain responded with an oil embargo and pushed for a coup to regain control.  In 1953, a CIA- and MI16-backed coup removed Prime Minister Mohammad Mossadegh, strengthening Shah Mohammad Reza Pahlavi's absolute rule.  (The coup is widely cited by historians as a primary cause for the 1979 Iranian Revolution, as it created deep-seated distrust of the West and resentment toward the Shah's subsequent 25-year autocratic rule.)

Under the Pahlavi’s, Iran became a major global oil power, its GDP per capita nearly tripled, and the country built one of the world's strongest militaries.  Critics highlight the regime's political repression and wealth inequality, while supporters view the era with nostalgia for its social freedoms and international prestige.

Cultural achievements during the Pahlavi dynasty focused on rapid modernization, secularization, and the revival of pre-Islamic Persian heritage, significantly expanding education and arts.  Key milestones included the expansion of public schooling, the Literacy Corps, founding of Tehran University, women’s suffrage, and fostering modern arts/festivals under Empress Farah Pahlavi.  The Literacy Corps and mandatory education policies significantly raised literacy rates. Kindergarten enrollment grew from 13,300 to over 221,000, while university enrollment soared.  Educational policies were redesigned to diminish traditional clerical control in favor of modern, secular education.  Major institutions were established, including the Tehran Museum of Contemporary Arts, Carpet Museum of Tehran, Reza Abbassi Museum, and Negarestan Museum.  Authentic Iranian arts were rejuvenated through "coffee house painting" and masters like Mahmoud Farshchian, who developed a distinct style.  Women gained the right to vote, run for office, and the marriageable age was raised.  Theater and film flourished in Tehran during the 1960s and 70s.  The Iran Cultural Foundation was established to preserve and promote Persian arts and culture. 

In the late 1970s, Mohammad Reza Pahlavi’s rule became increasingly autocratic, relying on the secret police to suppress dissent, which led to his overthrow in 1979, and the establishment of the Islamic Republic of Iran. 

Mohammad Reza Pahlavi was the last Shah of Iran, ruling from 1941 until his overthrow during the Islamic Revolution in 1979.
