History

Iran also known as Persia, (officially the Islamic Republic of Iran) is a sovereign state in Western Asia, with over 79.92 million inhabitants (as of August 2017) and the world’s 18th most-populous country. Comprising area of 1,648,195 km2, it is the 2nd in the Middle East and the 17th largest country in the world.

Iran is bordered to the northwest by Armenia, the de facto independent Republic of Artsakh, the Republic of Azerbāijān, and Nakhichevan; 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 the Gulf of Oman; and to the west by Turkey and Iraq. The country’s central location in Eurasia, Western Asia, and proximity to the Strait of Hormuz, led to geostrategic importance.

Tehran is the country’s capital and largest city, as well as its leading economic and cultural center. Iran is home to one of the world’s oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Iranian Medes in the 7th century BC, and reached its greatest extent during the Achaemenid Empire founded by Cyrus the Great in the sixth century BC, stretching from Eastern Europe to the Indus Valley, becoming a larger empire than previously ever existed in the world.

The Iranian realm fell to Alexander the Great in the fourth century BC, but reemerged shortly after as the Parthian Empire, followed by the Sasanian Empire, which became a leading world power for the next four centuries. Arab Muslims conquered the empire in the seventh century AD, ultimately leading to the displacement of the indigenous faiths of Zoroastrianism and Manichaeism with Islam.

Iran had major contributions to the Islamic Golden Age that followed, producing many influential figures in art and science. After two centuries, a period of various native Muslim dynasties began, which were later conquered by the Turks and the Mongols.

The rise of the Safavids in the 15th century led to the reestablishment of a unified Iranian state and national identity, which followed the country’s conversion to Shia Islam, marking a turning point in Iranian and Muslim history. By the 18th century, under Nader Shah, Iran briefly possessed what was arguably the most powerful empire at the time. The 19th century conflicts with the Russian Empire led to significant territorial loss.

Popular unrest culminated in the Constitutional Revolution of 1906, which established a constitutional monarchy and the first legislature. Following a coup instigated by the United Kingdom and the United States in 1953, Iran gradually became closely aligned with the West, and grew increasingly autocratic. Growing dissent against foreign influence and political repression led to the 1979 Revolution, which followed the establishment of an Islamic republic, a political system which includes elements of a parliamentary democracy vetted and supervised by “Supreme Leader”. During the 1980s, the country was engaged in a war with Iraq, which lasted for almost nine years and resulted in a high number of casualties and financial loss for both sides.

Ayatollah Seyyed Ali Khamenei has been Iran's Supreme Leader since 1989. The Joint Comprehensive Plan of Action (JCPOA), an agreement reached between Iran and the P5+1, was created on July 14, 2015, aimed to loosen the nuclear sanctions in exchange for Iran’s restriction in producing enriched uranium. Iran is a founding member of the UN, ECO, NAM, OIC, and OPEC and a major regional power with large reserves of fossil fuels – which include the world’s largest natural gas supply and the fourth-largest proven oil reserves– exert considerable influence in international energy security and the world economy.

The country’s rich cultural legacy is reflected in part by its 24 UNESCO World Heritage Sites, the third-largest number in Asia and eleventh-largest in the world. Iran is a multicultural country comprising numerous ethnic and linguistic groups, the largest being Persians (61%), Azeris (16%), Kurds (10%), and Lors (6%).

490-479 BC -- In their wars with Persia, the Greek city-states were never a threat to the Persian heartland. Persia did not achieve its property wars; it was obtained through diplomacy. The Persian influence over the two Greek city-states was such that the Persian King Artaxerxes II was asked to mediate between them, leading to the King's Peace of 387 BC.

550-334 BC -- The Persian Empire became the dominant world power for over two centuries. It made possible the first significant and continuous contact between East and West. It was the world's first religiously tolerant empire.

Alexander to Parthian Dynasty

334 BC -- Alexander Invaded Persia. After his victory over the Persian army, he ordered the execution of many Persians, allowed his troops to indulge themselves in plunder and rape and set fire to Persepolis.

323 BC -- Alexander died. Although a masterful general, he lacked administrative skills. Shortly after his death, his empire was divided among his contesting generals.

Seleucid Dynasty

323-141 BC -- The Seleucid Dynasty was established by one of Alexander's generals.

Parthians Dynasty

247 BC-224 AD -- The Parthians, a tribal kingdom from northeastern Iran, gradually defeated the Greek Seleucids and consolidated their control over Persia. The name of the founder of the dynasty, Arsaces, became the title of all Parthian kings. Their victory over the Romans in 53 BC elevated the Parthians into a superpower of their era

Sassanid Dynasty

224 AD-- Ardeshir I founded the Sasanian dynasty. The Sasanians revived Persian culture and Zoroastrianism and made a conscious effort to return to the Achaemenian norms. They sponsored trade both with their arch-enemy, the Romans/Byzantines, and the Chinese.

Arab Caliphate

642 AD -- After successfully defending itself against the Roman/Byzantine Empires for centuries, the Persian Empire was swiftly vanquished by nomadic tribesmen armed with a newly acquired Islamic faith. Islam's ideals of equality and unity appealed to many Persians, as they were in sharp contrast to the rigid and hierarchical social structure of the later Sasanian period.

661 AD -- Imam Ali, the Prophet Mohammad's son-in-law and the fourth and last of the "rightly guided caliphs," was assassinated, thus leading to the great schism in Islam between the Sunni and Shi'ite sects. Although Persia did not become a Shi'ite state for almost another nine centuries, this clash was pivotal in its history.

Umayyad Dynasty

661-750 AD -- The Umayyad Caliphate emerged as the rulers of the Islamic world. Although they maintained the Sasanians' administrative practices, the Umayyads considered Islam as primarily an Arab religion and were wary of Persian culture. They tried to force the Arabic language upon the Persians, leading to the demise of the Middle Persian or Pahlavi alphabet in favor of the new Arabic/Persian alphabet in use to this day.

750-1258 AD -- The Abbasid Caliphate relied on Persian ministers and bureaucracy for many state functions. Persian customs began to take deep roots under the Abbasids. The offices of the vizier (minister) and the divan (or bureau for state revenue) were copied from the Sasanian model and later caliphs adopted the Persian courts' ceremonial procedures and the trappings of the Sasanian kings.

Persia's Cultural Golden Age

820-1220 AD -- Arab rule over Persia began to diminish as various local Persian monarchs rose to power: The Taherids (821-873), Saffaarids (867-903), Samanids (873-999), Ziyarids (928-1077) and Buyids (945-1055). They were followed by Turkic dynasties with Persian culture: The Ghaznavids (962-1186), Seljuqs (1038-1153) and Khwarazmis (1153-1220). Once again, Persia became a world center for art, literature and science. Key figures in nearly all fields of endeavor in the Islamic world.

850 AD -- Kharazmi, a remarkable mathematician and astronomer, wrote precise astronomical tables and the first work of algebra, The Book of Integration & Equation. The word "algebra" is derived from this book's title and the word "algorithm" from his own name. He helped establish the concept of zero and perfect the decimal system. The culmination of his work, along with that of other Islamic scholars, produced the Arabic numerals - a modified version of which replaced the Roman numerals in the West and which is still in use to this day.

Shahnameh consists of mythical stories of pre-Islamic Persia. The book's chief epic hero is a noble knight named Rostam, who embodies values such as integrity, strength and chivalry.

980-1037 AD -- Ibn Sina (Avicenna), one of the most significant scientists and philosophers of the Islamic civilization, wrote over 200 books, including The Cannon of Medicine, an encyclopedia summarizing all the then known medical knowledge from across the world.

Seljuk Dynasty

1405 AD -- Timur (Tamerlane), a Turco-Mongol leader, conquered much of Persia and its surrounding areas. His conquests yet again consisted of unimaginable cruelty and devastation. Although brutal, he was also a patron of arts. He made Samarqand his capital and brought artists from all over Persia. 1429 AD -- Jamshid Kashani, a major mathematician, advanced number theory, invented the first calculating machine and participated in the astronomical activities at Samarqand.

Safavid Dynasty

Qajar Dynasty

1795 AD -- Although the Qajars succeeded in reuniting the country, they were generally weak and corrupt rulers. The economic and military gap between Iran and the West widened considerably under their reign - especially in light of the Industrial Revolution that was taking place in the West. However, the Qajar period also enjoyed a high degree of artistic excellence, producing some of Iran's finest paintings, tileworks and architectural monuments.

1813 & 1828 AD -- European imperialism resulted in English and Russian penetration in Iranian affairs. The Qajars lost the Caucasus (present day Georgia, Armenia and Azerbaijan) to the Russians in two separate treaties: The Golestan in 1813 and the Torkmanchay in 1828. As a result of the 1828 treaty, the Qajars were forced to enact the "Capitulation" law, exempting all foreign citizens from Iranian jurisdiction. This law deeply humiliated the Iranian people.

1851-1906 AD -- The Qajars lost central Asian provinces to the Russians and were forced to give up all claims on Afghanistan to the British.

Pahlavi Dynasty

1925-1941 AD -- Reza Shah Pahlavi's first priority was to strengthen the authority of the central government by creating a disciplined standing army and restraining the autonomy of the tribal chiefs. Politically, however, Reza Shah forcibly abolished the wearing of the veil, took away the effective power of the Majles and did not permit any forms of free speech. With the outbreak of WW II, Reza Shah, wanting to remain neutral, refused to side with the Allies.

1941-1944 AD -- In need of the Trans-Iranian railway to supply the Soviets with wartime materials, the Allies invaded and occupied Iran for the duration of the war. Reza Shah was forced to abdicate in favor of his son Mohammad Reza Pahlavi and died in South Africa in exile in 1944.

1962-1963 AD -- The Shah introduced his White Revolution. It consisted of major land reform, workers' rights and women's suffrage, among other initiatives. His reforms did not develop as planned due to poor execution.

1963-1973 AD -- Iran experienced rapid economic growth and prosperity coupled with a relatively stable political climate.

1973 AD-- The oil embargo quadrupled Iran's oil revenue to $20 billion a year. This new wealth accelerated the Shah's timetable to make Iran "catch up" with the West. The Shah's determination to modernize Iran virtually overnight and at any cost led to cultural shock, alienation of the masses, inflation, corruption, economic bottlenecks, massive urbanization, rising expectations and increasing authoritarianism in dealing with these social, economic and political problems.

Islamic Republic of Iran

1979 AD - By the late 1970s, the Shah's opponents, of all political affiliations, united with Ayatollah Khomeini.
