37°36′N 47°00′E / 37.6°N 47.0°E / 37.6; 47.0 Azerbaijan or Azarbaijan (Persian/Azerbaijani: آذربایجان, romanized: Āzarbāyjān, Persian pronunciation: [ɒːzæɾbɒːjˈdʒɒːn], Azerbaijani pronunciation: [ɑːzæɾbɑjˈdʒɑn]), also known as Iranian Azerbaijan,^[1] is a historical region in northwestern Iran that borders Iraq and Turkey to the west and Armenia, Azerbaijan, and the Azerbaijani exclave of the Nakhchivan Autonomous Republic to the north.

Iranian Azerbaijan includes three northwestern Iranian provinces: West Azerbaijan, East Azerbaijan and Ardabil.^[2][3] Some authors also include Zanjan in this list, some in a geographical sense,^[4] others only culturally (due to the predominance of the Azeri Turkic population there).^[5] The region is mostly populated by Azerbaijanis, with minority populations of Kurds, Armenians, Tats, Talysh, Assyrians and Persians.

Iranian Azerbaijan is the land originally and historically called Azerbaijan; the Azerbaijani-populated Republic of Azerbaijan appropriated the name of the neighbouring Azerbaijani-populated region in Iran during the 20th century.^[6][7][8] Historic Azerbaijan was called Atropatene in antiquity and Aturpatakan (Adurbadagan) in the pre-Islamic Middle Ages. Some people refer to Iranian Azerbaijan as South (or Southern) Azerbaijan and the Republic of Azerbaijan as Northern Azerbaijan,^[9] although others believe that these terms are irredentist and politically motivated.^[10][11][12]

Following military defeats at the hands of the Russian Empire, Qajar Persia ceded all of its territories in the North Caucasus and Transcaucasia to Russia via the Treaty of Gulistan of 1813 and the Treaty of Turkmenchay of 1828.^[13] The territories south of the Aras River, which comprised the region historically known as Azerbaijan, became the new north-west frontier of the Persian Empire and later Iran.^[14] The territories north of the Aras River, which were not known by the name Azerbaijan at the time of their capture by Russia, were absorbed into the Russian Empire, renamed the Azerbaijan Democratic Republic during the country's short-lived independence from 1918 to 1920,^[15] incorporated into the Soviet Union as the Azerbaijan Soviet Socialist Republic, and finally became the independent Republic of Azerbaijan when the Soviet Union dissolved.

The name Azerbaijan itself is derived from Atropates,^[16] the Persian^[17][18][19] Satrap (governor) of Medea in the Achaemenid Empire, who ruled a region found in modern Iranian Azerbaijan called Atropatene. Atropates's name is believed to be derived from the Old Persian roots meaning "protected by fire."^[20] The name is also mentioned in the Avestan Frawardin Yasht: âterepâtahe ashaonô fravashîm ýazamaide which translates literally to: "We worship the Fravashi of the holy Atare-pata."^[21] According to the Encyclopaedia of Islam: "In Middle Persian the name of the province was called Āturpātākān, older new-Persian Ādharbādhagān (آذربادگان/آذرآبادگان), Ādharbāyagān, at present Āzerbāydjān/Āzarbāydjān, Greek Atropatēnḗ (Ἀτροπατηνή), Byzantine Greek Adravigánon (᾿Αδραβιγάνων), Armenian Atrpatakan (Ատրպատական), Syriac Adhorbāyghān."^[22] The name Atropat in Middle Persian was transformed to Adharbad and is connected with Zoroastrianism. A famous Zoroastrian priest by the name Adarbad Mahraspandan is well known for his counsels.^[23] Azerbaijan, due to its numerous fire-temples has also been quoted in a variety of historic sources as being the birthplace of the prophet Zoroaster although modern scholars have not yet reached an agreement on the location of his birth.^[24]

In the early 19th century, Qajar Iran was forced to cede to Imperial Russia its Caucasian territories north of the Aras River (modern-day Dagestan, Georgia, Armenia, and the Republic of Azerbaijan), through the treaties of Gulistan (1813) and Turkmenchay (1828). Following the disintegration of the Russian Empire in 1917, as well as the short-lived Transcaucasian Democratic Federative Republic, in 1918, the leading Musavat government adopted the name "Azerbaijan" for the newly established Azerbaijan Democratic Republic, which was proclaimed on May 27, 1918,^[25] for political reasons,^[26][27] even though the name of "Azerbaijan" had always been used to refer to the adjacent region of contemporary northwestern Iran.^[6][7][8] Thus, until 1918, when the Musavat regime decided to name the newly independent state Azerbaijan, this designation had been used exclusively to identify the Iranian province of Azerbaijan.^{[7][8][15][28]}

The oldest kingdom known in Iranian Azerbaijan is that of the Mannea who ruled a region south-east of Lake Urmia centered around modern Saqqez. The Manneans were a confederation of Iranian and non-Iranian groups. According to Professor Zadok:

it is unlikely that there was any ethnolinguistic unity in Mannea. Like other peoples of the Iranian plateau, the Manneans were subjected to an ever-increasing Iranian (i.e., Indo-European) penetration.^[29]

The Mannaeans were conquered and absorbed by an Iranian people called Matieni, and the country was called Matiene, with Lake Urmia called Lake Matianus. Matiene was later conquered by the Medes and became a satrapy of the Median empire and then a sub-satrapy of the Median satrapy of the Persian Empire.

According to Encyclopædia Britannica, the Medes were an:

Indo-European people, related to the Persians, who entered northeastern Iran probably as early as the 17th century BC and settled in the plateau land that came to be known as Media.^[30]

After Alexander the Great conquered Persia, he appointed (328 BC) as governor the Persian general Atropates, who eventually established an independent dynasty. The region, which came to be known as Atropatene or Media Atropatene (after Atropates), was much disputed. In the 2nd century BC, it was liberated from Seleucid domination by Mithradates I of Arsacid dynasty, and was later made a province of the Sassanid Empire of Ardashir I. Under the Sassanids, Azerbaijan was ruled by a marzubān, and, towards the end of the period, belonged to the family of Farrokh Hormizd.

Large parts of the region were conquered by the Kingdom of Armenia. Large parts of the region made up part of historical Armenia. The parts of historical Armenia within what is modern-day Azerbaijan comprise; Nor Shirakan, Vaspurakan, and Paytakaran. Vaspurakan, of which large parts were located in what is modern-day Iranian Azerbaijan is described as the cradle of Armenian civilization.^[31]

On 26 May 451 AD, a very important battle was fought that would prove immensely pivotal in Armenian history. On the Avarayr Plain, at what is modern-day Churs (modern-day West Azerbaijan Province), the Armenian Army under Vardan Mamikonian clashed with Sassanid Persia. Although the Persians were victorious on the battlefield itself, the battle proved to be a major strategic victory for Armenians, as Avarayr paved the way to the Nvarsak Treaty (484 AD), which affirmed Armenia's right to practice Christianity freely.^[32][33]

Heraclius, the Byzantine emperor, briefly held the region in the 7th century until peace was made with the Sassanids. After the Islamic Conquest of Iran, Arab invaders converted most of its people to Islam and made it part of the caliphate.

During the Arab invasion of Iran, the Spahbed of Iran was Rostam Farrokhzad, the son of Farrukh Hormizd, who was the son of Vinduyih, the uncle of Khosrau I and brother of the Sasanian usurper Vistahm. Rustam himself was born in Azerbaijan and led the Sasanian army into battle. He is also mentioned in the Shahnameh.

The Sasanian army was defeated at the battle of al-Qādisiyyah and Rostam Farrokhzad, along with many other Sasanian veterans, was killed. In 642, Piruz Khosrow, one of the Sasanian survivors during the battle of al-Qādisiyyah, fought against the Muslims at Nahavand, which was a gateway to the provinces of Azerbaijan, Armenia and Caucasian Albania. The battle was fierce, but the Sasanian troops lost during the battle. This opened the gateway for the Muslims to enter Azerbaijan. The Muslims then invaded Azerbaijan and captured Isfandiyar, the son of Farrukhzad. Isfandiyar then promised, in return for his life, that he would agree to surrender his estates in Azerbaijan and aid the Muslims in defeating his brother, Bahram. Bahram was then defeated and sued for peace. A pact was drawn up according to which Azerbaijan was surrendered to Caliph Umar on usual terms of paying the annual Jizya.

Muslims settled in Azerbaijan as they did in many parts of Iran. According to the Iranian Azerbaijani historian Ahmad Kasravi, more Muslims settled in Azerbaijan compared to other provinces due to the province's plentiful and fertile pastures. Local revolts against the Caliphate were common and the most famous of these revolts was the Persian Khurramite movement.

After the revolt of Babak Khorramdin, who was a Zoroastrian of neo-Mazdakite background, the Abbasid caliphate's grip on Azerbaijan weakened, allowing native dynasties to rise in Azerbaijan. Azerbaijan was taken over by the Kurdish Daisam and the Sallarid Marzuban, the latter united it with Arran, Shirvan, and most of Eastern Armenia. After confrontations with the local Dailamite and Kurdish populations who had already established their own dynasties and emirates in different parts of Azerbaijan, the Seljuks dominated the region in the 11th and early 12th centuries, at which point the linguistic Turkification of the native Iranian populations began. In 1136, Azerbaijan fell to the Atabakan-e-Azerbaijan and Atabakan-e-Maragheh. It was later invaded by the Khwarizm Shah Jalal ad-din who held Azerbaijan until the advent of the Mongol invasions.

In the early years of the 13th century, large parts of Azerbaijan were conquered by the Kingdom of Georgia, at the time led by Tamar the Great. Under the command of the brothers Zakaria and Ivane Mkhargrdzeli, the Georgians conquered Ardabil and Tabriz in 1208, and Qazvin and Khoy in 1210.^{[34][35][36][37]}

The Mongols under Hulagu Khan established their capital at Maragheh. The book Safina-yi Tabriz describes the general state of Tabriz during the Ilkhanid period. After being conquered by Timur in the 14th century, Tabriz became an important provincial capital of the Timurid empire. Later, Tabriz became the capital of the Kara Koyunlu empire.

It was out of Ardabil (ancient Artavilla) that the Safavid dynasty arose to renew the state of Persia and establish Shi'ism as the official religion of Iran. Around the same time, the population of what is now Azerbaijan and Iran were converted to Shiism,^[38] and both nations remain the only nations in the world with a significantly Shia majority, with Iran having the largest Shia population by percentage, with the Republic of Azerbaijan having the second-largest Shia population by percentage.^[39][40]

After 1502, Azerbaijan became the chief bulwark and military base of the Safavids. It was the chief province from which the various Iranian empires would control their Caucasian provinces, all the way up to Dagestan in the early 19th century. In the meantime, between 1514 and 1603, the Ottomans sometimes occupied Tabriz and other parts of the province during their numerous wars with their Safavid ideological and political archrivals. The Safavid control was restored by Shah Abbas but during the Afghan invasion (1722–8) the Ottomans recaptured Azerbaijan and other western provinces of Iran, until Nader Shah expelled them. At the beginning of the reign of Karim Khan Zand, the Azad Khan Afghan unsuccessfully revolted in Azerbaijan and later the Dumbuli Kurds of Khoy and other tribal chiefs ruled various parts of the territory. Azad Khan was defeated however by Erekle II. With the advent of the Qajars, Azerbaijan became the traditional residence of the heirs-apparent. Even until then Azerbaijan remained the main area from where the high-ranked governors would control the various territories and Khanates of the Caucasus while the main power stayed in Tehran.

Though the first Qajar Iranian ruler, Agha Mohammad Khan, had reconquered the Caucasus and all of Iran in several swift campaigns, such as the harsh re-subjugation of Georgia in 1795, Iran would eventually irrevocably lose all of the Caucasus region to neighbouring Imperial Russia during the course of the 19th century, which had a crucial impact on the region of modern-day Iranian Azerbaijan. Shortly after the reconquest of Georgia, Agha Mohammad Shah was assassinated while preparing a second expedition in 1797 in Shusha.^[41] The reassertion of Iranian hegemony over Georgia did not last long; in 1799 the Russians marched into Tbilisi,^[42] which would mark the beginning of the end of the Iranian-ruled domains in the Caucasus, comprising modern-day Georgia, Armenia, the Republic of Azerbaijan, and Dagestan thanks to the 19th century Russo-Persian Wars.^[14]

Since the late 17th/early 18th century, the Russians were actively pursuing an expansionist policy towards its neighbouring empires to its south, namely the Ottoman Empire and the successive Iranian kingdoms. Agha Mohammad Khan's death and the Russian troops entering the Iranian possession of Tbilisi in 1799, led directly to the Russo-Persian War (1804–1813), the first of a number of Russo-Persian wars during the 19th century,^[41] and the most devastating and humiliating one. By the end of the war in 1813 and the resulting Treaty of Gulistan, Qajar Iran was forced to cede Georgia, most of the modern-day Republic of Azerbaijan, and Dagestan to Russia. The only Caucasian territories remaining in Iranian hands were what is now Armenia, the Nakhichevan Khanate, and the Talysh Khanate. The next war, the Russo-Persian War (1826–1828), resulted in an even more humiliating defeat, with Iran being forced to cede the remaining Caucasian regions,^[14] as well as having Russian troops temporarily occupying Tabriz and Iranian Azerbaijan. As Iran was unwilling to allow the Russians to gain possession over its Caucasian territories in the North Caucasus and South Caucasus, the millennia-old ancient ties between Iran and the Caucasus region were only severed by the superior Russian force of Russia through these 19th-century wars.^[41]

The area to the north of the river Aras, which included the territory of the contemporary republic of Azerbaijan, eastern Georgia, Dagestan, and Armenia, were Iranian territory until they were occupied by Russia during the 19th century.^{[13][14][43][44][45][46][47]}

Through the course of the 19th century Iran lost to Russia regions^[14] which had been part Iran for centuries.^[41] By the end of the 19th century, the border between Iran and Russia was set more southwards, at the Aras River, which is currently the border between Iran and Armenia – Azerbaijan.

Subsequently, the Russians were very influential in Northern Iran including Azerbaijan (as Northern Iran fell into Russia's sphere of influence for decades). After 1905, the representatives of Azerbaijan were very active in the Iranian Constitutional Revolution as a result to this Russian influence.

The Russian (Tsarist) army occupied Iranian Azerbaijan in 1909 and again in 1912–1914 and 1915–1918, followed by Ottoman forces in 1914–1915 and 1918–1919; Bolshevik forces occupied Iranian Azerbaijan and other parts of Iran in 1920–1921,^[48] and Soviet forces occupied Iranian Azerbaijan in 1941, creating a very short-lived autonomous, Soviet-supported state from November 1945 to November 1946,^[49] which was dissolved after the reunification of Iranian Azerbaijan with Iran in November of the same year. The period roughly from the last major Russo-Persian War up to this date is so-called the period of high Russian influences in Iran. All of Northern Iran, including Iranian Azerbaijan, Gilan, Mazandaran, Qazvin, and many other places all the way up to Isfahan fell into the Russian sphere of influence. Russian armies were stationed in many regions of Iranian Azerbaijan, Russian schools were founded, and many Russians settled in the region, but less than in Gilan and Mazandaran. Also, Azerbaijan saw the large influx of the so-called White émigrées who fled to Iran following the Bolshevik revolution in Russia. Iranian nationalism is partly the product of Azerbaijani intellectuals.^[50][51] Azerbaijani provinces have played a major in the cultural and economic life of Iran in both the Pahlavi era as well as the Iranian Constitutional and Islamic revolution.

The Iranian provinces of Azerbaijan, both West and East, possess a large number of monuments from all periods of history.^[52]

Iranian Azerbaijan is generally considered the north-west portion of Iran comprising the provinces of East Azerbaijan, West Azerbaijan, and Ardabil.^[53] It shares borders with the Republic of Azerbaijan,^[54] Armenia, Turkey, and Iraq. There are 17 rivers and two lakes in the region. Cotton, nuts, textiles, tea, machinery, and electrical equipment are the main industries. The northern, alpine region, which includes Lake Urmia, is mountainous, with deep valleys and fertile lowlands.

The region is bounded in the north by Armenia and the Republic of Azerbaijan and in the West by Lake Urmia and Kurdish-inhabited areas of Iran, and in the East by Gilan.

Azerbaijani people mostly live in northwest parts of Iran, but large Azerbaijani populations can be found in Khorasan,^[116] mostly in Mashhad,^[117] as well as central Iran, due to internal migration to Tehran,^[116] Karaj,^[106] and Qum.^[116] Where they have settled, they have become prominent – not only among urban and industrial working classes – but also in commercial, administrative, political, religious, and intellectual circles.^[116] Azerbaijanis make up 25%–33%^[105][106] of Tehran and of Tehran Province's population. They are the largest ethnic groups after Persians in Tehran and the Tehran Province.^[118] The governor of Tehran is Hossein Hashemi^[119] from Sarab; he was born in East Azerbaijan;^[120] Ali Khamenei, the Supreme Leader of Iran, was born in Mashhad and is of Azeri origin.^{[121][122][123]} The journals Varliq and Azari are printed by the Azerbaijani people in Tehran.

Azerbaijanis have influenced Iranian culture while also being influenced by their non-Iranian neighbors, particularly Caucasians and Russians. The majority of Azerbaijanis in both Iran and the Republic of Azerbaijan are Shiite Muslims. They celebrate Nowruz, the Iranian new year, at the arrival of spring. Azerbaijan has a distinct music that is tightly connected to the music of other Iranian peoples such as Persian music and Kurdish music, and also the music of the Caucasian peoples. Although the Azerbaijani language is not an official language of Iran it is widely used, mostly orally, among the Iranian Azerbaijanis.^{[citation needed]}

Many poets that came from Azerbaijan wrote poetry in both Persian and Azerbaijani. Renowned poets in Azerbaijani language are Nasimi, Shah Ismail I (who was known with the pen-name “Khata'i”), Fuzuli, Nasimi, and Jahan Shah were probably born outside what is now Iranian Azerbaijan. Azerbaijani was the dominant language of the Turkish ruling dynasties of the area, such as Ak Koyunlu,^[132] Kara Koyunlu,^[133] and was later used in the Safavid court, until Isfahan became the capital,^[134] and by religious, military and state dignitaries.^[135][136] In the 16th century, Azerbaijani literature further flourished with the development of Ashik (Azerbaijani: Aşıq) poetic genre of bards. During the same period, under the pen-name of “Khaṭāʾī” (Azerbaijani: خطائی, lit. 'the Cathayan')^[137][138] Shah Ismail I wrote about 1,400 verses in Azerbaijani,^[139] which were later published as his Divan. A unique literary style known as qoshma (Azerbaijani: qoşma for improvisation) was introduced in this period, and developed by Shah Ismail and later by his son and successor, Shah Tahmasp and Tahmasp I.^[132] In the span of the 17th century, 18th and 19th century, Fizuli's unique genres as well Ashik poetry were taken up by prominent poets and writers such as Qovsi Tabrizi, Shah Abbas Sani, Khasta Qasim, Mirza Fatali Akhundov, Seyid Abulgasim Nabati, Ali Mojuz and others.

An influential piece of post-World War II Azerbaijani poetry, Heydar Babaya Salam (Greetings to Heydar Baba) was written by Azeri poet Mohammad Hossein Shahriar. This poem, published in Tabriz in 1954 and written in colloquial Azerbaijani, became popular among Iranians and the people of Azerbaijan Soviet Socialist Republic. In Heydar Babaya Salam, Shahriar expressed his identity as an Iranian attached to his homeland, language, and culture. Heydar Baba is a hill near Khoshknab, the native village of the poet.

Azerbaijan is mentioned favorably on many occasions in Persian literature by Iran's greatest authors and poets. Examples:

گزیده هر چه در ایران بزرگان
زآذربایگان و ری و گرگان
All the nobles and greats of Iran,
Choose from Azerbaijan, Ray, and Gorgan.
—Vis o Ramin

از آنجا بتدبیر آزادگان
بیامد سوی آذرآبادگان
From there the wise and the free,
