Erbil

Archaeology

In 2006 a small excavation was conducted by Karel Novacek of the University of West Bohemia. While the citadel remains were of the Ottoman Period, a field survey of the western slope of the tell found a few pottery shards from the Neolithic to Middle Bronze Age with more numerous finds from the Late Bronze to Iron Ages and from the Hellenistic, Arsacid, Sassanid Periods. Being so heavily occupied, the site has never been properly excavated. In 2013 a team from the Sapienza University of Rome conducted some ground penetrating radar work on the center of the citadel. Starting in 2014 an Iraqi-led excavation began on a citadel location where the collapse of a modern building provided an opportunity for excavation. Historical aerial photographs and ground surveys have also begun on the lower city.

The wider plain around Erbil has a number of promising archaeological sites, most notably Tell Baqrta. The Erbil Plain Archaeological Survey began in 2012. The survey combines satellite imagery and field work to determine the development and archaeology of the plain around Erbil. Tell Baqrta is a very large, 80 hectare, site which dates back to the Early Bronze Age.

History

Neolithic

Erbil was among the earliest regions of agricultural settlement during the Neolithic period, marking a significant stage in the development of human civilization in Mesopotamia.

Bronze Age

Early Bronze

The region in which Erbil lies was largely under Sumerian domination from c. 3000 BC.

With the rise of the Akkadian Empire (2335–2154 BC) all of the Akkadian Semites and Sumerians of Mesopotamia were united under one rule. Erridupizir, king of the kingdom of Gutium, captured the city in 2150 BC.

The first mention of Erbil in literary sources comes from the archives of the kingdom of Ebla. They record two journeys to Erbil (Irbilum) by a messenger from Ebla around 2300 BFC.

The Neo-Sumerian ruler of Ur, Amar-Sin, sacked Urbilum in his second year, c. 1975 BC.

Middle Bronze

In the centuries after the fall of the Ur III empire Erbil became a power in its area. It was conquered by Shamsi-Adad during his short lived Kingdom of Upper Mesopotamia, becoming independent after its fall.

Late Bronze

By the time of the Middle Assyrian Empire (1365–1050 BC) Erbil was within the Assyrian zone of control.

Iron Age

The region fell under the Neo-Assyrian Empire (935–605 BC). The city then changed hands a number of times including the Persian, Greek, Parthian, Roman and Sassanid rule.

Under the Medes, Cyaxares might have settled a number of people from the ancient Iranian tribe of Sagartians in the Assyrian cities of Arbela and Arrapha (modern Kirkuk), probably as a reward for their help in the capture of Nineveh. According to Classical authors, the Persian emperor Cyrus the Great occupied Assyria in 547 BC and established it as an Achaemenid military protectorate state (or satrapy) called in Old Persian Aθurā (Athura), with Babylon as the capital.

The Medes, and with them the Sagarthians, were to revolt against Darius I of Persia in 522 BC, but this revolt was firmly put down by the army which Darius sent out under the leadership of General Takhmaspada the following year. The events are depicted in the Behistun Inscription which stands today in the mountains of Iran's Kermanshah province.

The Battle of Gaugamela, in which Alexander the Great defeated Darius III of Persia, took place in 331 BC approximately 100 kilometres (62 mi) west of Erbil according to Urbano Monti's world map. After the battle, Darius managed to flee to the city. (Somewhat inaccurately, the confrontation is sometimes known as the "Battle of Arbela".) Subsequently, Arbela was part of Alexander's Empire. After the death of Alexander the Great in 323 BC, Arbela became part of the Hellenistic Seleucid Empire.

Erbil became part of the region disputed between Rome and Persia under the Sasanids. During the Parthian era to early Sassanian era, Erbil became the capital of the state of Adiabene (Assyrian Ḥadyab). The town and kingdom are known in Jewish history for the conversion of the royal family, notably Queen Helena of Adiabene, to Judaism.

Its populace then gradually converted from the ancient Mesopotamian religion between the first and fourth centuries to Christianity, with Pkidha traditionally becoming its first bishop around 104 AD. The ancient Mesopotamian religion did not die out entirely in the region until the tenth century AD. There also existed a Christian community thought to be converts from Judaism. The Adiabene (East Syriac ecclesiastical province) in Arbela (Syriac: ܐܪܒܝܠ Arbel) became a centre of eastern Syriac Christianity until late in the Middle Ages.

Medieval history

As many of the Assyrians who had converted to Christianity adopted Biblical (including Jewish) names, most of the early bishops had Eastern Aramaic or Jewish/Biblical names, which does not suggest that many of the early Christians in this city were converts from Judaism. It served as the seat of a Metropolitan of the Assyrian Church of the East. From the city's Christian period come many church fathers and well-known authors in Aramaic.

Following the Muslim conquest of Persia, the Sassanian province of Naxwardašīragān and later Garamig ud Nodardashiragan, of which Erbil made part of, was dissolved, and from the mid-seventh century AD the region saw a gradual influx of Muslim peoples, predominantly Arabs and Turkic peoples.

The most notable Kurdish tribe in the region was the Hadhabani, of which several individuals also acted as governors for the city from the late tenth century until the 12th century when it was conquered by the Zengids and its governorship given to the Turkic Begtegenids, of whom the most notable was Gökböri, who retained the city during the Ayyubid era. Yaqut al-Hamawi further describes Erbil as being mostly Kurdish-populated in the 13th century.

When the Mongols invaded the Near East in the 13th century, they attacked Arbil for the first time in 1237. They plundered the lower town but had to retreat before an approaching Caliphate army and had to put off the capture of the citadel. After the fall of Baghdad to Hülegü and the Mongols in 1258, the last Begtegenid ruler surrendered to the Mongols, claiming the Kurdish garrison of the city would follow suit; they refused this however, therefore the Mongols returned to Arbil and were able to capture the citadel after a siege lasting six months. Hülegü then appointed a Christian Assyrian governor to the town, and the Syriac Orthodox Church was allowed to build a church.

As time passed, sustained persecutions of Christians, Jews and Buddhists throughout the Ilkhanate began in earnest in 1295 under the rule of Oïrat amir Nauruz, which affected the indigenous Christian Assyrians greatly. This manifested early on in the reign of the Ilkhan Ghazan. In 1297, after Ghazan had felt strong enough to overcome Nauruz's influence, he put a stop to the persecutions.

During the reign of the Ilkhan Öljeitü, the Assyrian inhabitants retreated to the citadel to escape persecution. In the Spring of 1310, the Malek (governor) of the region attempted to seize it from them with the help of the Kurds. Despite the Turkic bishop Mar Yahballaha's best efforts to avert the impending doom, the citadel was at last taken after a siege by Ilkhanate troops and Kurdish tribesmen on 1 July 1310, and all the defenders were massacred, including many of the Assyrian inhabitants of the lower town.

However, the city's Assyrian population remained numerically significant until the destruction of the city by the forces of Timur in 1397.

In the Middle Ages, Erbil was ruled successively by the Umayyads, the Abbasids, the Buwayhids, the Seljuks and then the Turkmen Begtegīnid Emirs of Erbil (1131–1232), most notably Gökböri, one of Saladin's leading generals; they were in turn followed by the Ilkhanids, the Jalayirids, the Kara Koyunlu, the Timurids and the Ak Koyunlu. Erbil was the birthplace of the famous 12th and 13th century Kurdish historians and writers Ibn Khallikan and Ibn al-Mustawfi. After the Battle of Chaldiran in 1514, Erbil came under the Soran emirate. In the 18th century Baban Emirate took the city but it was retaken by Soran ruler Mir Muhammed Kor in 1822. The Soran emirate continued ruling over Erbil until it was taken by the Ottomans in 1851. Erbil became a part of the Mosul vilayet in Ottoman Empire until World War I, when the Ottomans and their Kurdish and Turkmen allies were defeated by the British Empire.

Modern history

Erbil lies on the plain beneath the mountains, but for the most part, the inhabitants of Iraqi Kurdistan dwell up above in the rugged and rocky terrain that is the traditional habitat of the Kurds since time immemorial.

The modern town of Erbil stands on a tell topped by an Ottoman fort. During the Middle Ages, Erbil became a major trading centre on the route between Baghdad and Mosul, a role which it still plays today with important road links to the outside world.

Erbil is also home to a large population of refugees due to ongoing conflicts in Syria. In 2020, it was estimated that 450,000 refugees had settled in the Erbil metropolitan area since 2003, with many of them expected to remain.

The parliament of the Iraqi Kurdistan was established in Erbil in 1970 after negotiations between the Iraqi government and the Kurdistan Democratic Party (KDP) led by Mustafa Barzani, but was effectively controlled by Saddam Hussein until the Kurdish uprising at the end of the 1991 Gulf War. The legislature ceased to function effectively in the mid-1990s when fighting broke out between the two main Kurdish factions, the Kurdistan Democratic Party and the Patriotic Union of Kurdistan (PUK). The city was captured by the KDP in 1996 with the assistance of the Iraqi government of Saddam Hussein. The PUK then established an alternative Kurdish government in Sulaimaniyah. KDP claimed that in March 1996, PUK asked for Iran's help to fight KDP. Considering this as a foreign attack on Iraq's soil, the KDP asked Saddam Hussein for help.

The Kurdish Parliament in Erbil reconvened after a peace agreement was signed between the Kurdish parties in 1997, but had no real power. The Kurdish government in Erbil had control only in the western and northern parts of the autonomous region. During the 2003 invasion of Iraq, a United States special forces task force was headquartered just outside Erbil. The city was the scene of celebrations on 10 April 2003 after the fall of the Ba'ath regime.

During the U.S. occupation of Iraq, sporadic attacks hit Erbil. Parallel bomb attacks against Eid celebrations killed 117 people in February 2004. Responsibility was claimed by Ansar al-Sunnah. A suicide bombing in May 2005 killed 60 civilians and injured 150 more outside a police recruiting centre.

The Erbil International Airport opened in the city in 2005.

In September 2013, a quintuple car bombing killed six people.

In 2015, the Assyrian Church of the East moved its seat from Chicago to Erbil.

In February 2021, a series of missiles hit the city killing two and injuring eight people. Further missile attacks took place in March 2022.

Transportation

Erbil International Airport is one of Iraq's busiest airports. Services include direct flights to many domestic destinations such as Baghdad international airport. There are international flights from Erbil to many countries; such as the Netherlands, Germany, Saudi Arabia, Austria, Turkey, Jordan and elsewhere around the world. There are occasionally seasonal flights from Erbil international airport. Erbil International Airport was briefly closed to international commercial flights in September 2017 by the Iraqi government in retaliation for the Kurdish independence vote but reopened in March 2018.

Another important form of transportation between Erbil and the surrounding areas is by bus. Among others, bus services offer connections to Turkey and Iran. A new bus terminal was opened in 2014. Erbil has a system of six ring roads encircling the city.

Climate

Erbil has a hot-summer Mediterranean climate (Köppen climate classification Csa), closely bordering a hot semi-arid climate (Köppen: BSh) with long, extremely hot summers and mild winters. Summers are arid, with little to no precipitation occurring between June and September. Winters are usually wet with occasional flooding, with January being the wettest month.

A downpour on 17 December 2021 caused flash floods in the area, killing 14 people.

Culture

Citadel of Erbil

The Citadel of Erbil is a tell or occupied mound in the historical heart of Erbil, rising between 25 and 32 metres (82 and 105 ft) from the surrounding plain. The buildings on top of the tell stretch over a roughly oval area of 430 by 340 metres (1,410 ft × 1,120 ft) occupying 102,000 square metres (1,100,000 sq ft). It has been claimed that the site is the oldest continuously inhabited town in the world. The earliest evidence for occupation of the citadel mound dates to the fifth millennium BC and possibly earlier. It appears for the first time in historical sources during the Ur III period and gained particular importance during the Neo-Assyrian Empire (tenth to seventh centuries BC) period. West of the citadel at Ary Kon quarter, a chamber tomb dating to the Neo-Assyrian Empire period has been excavated. During the Sassanian period and the Abbasid Caliphate, Erbil was an important centre for Syriac Christianity and the Assyrians in general. After the Mongols captured the citadel in 1258, Erbil's importance began to decline. The main gate is guarded by an immense statue of a Kurd reading: "the house of the citadel behind him are built into stony ground of the mound and look down on the streets and tarmacked roads that circle them".

During the 20th century, the urban structure was significantly modified, as a result of which a number of houses and public buildings were destroyed. In 2007, the High Commission for Erbil Citadel Revitalization (HCECR) was established to oversee the restoration of the citadel. In the same year, all inhabitants, except one family, were evicted from the citadel as part of a large restoration project. Since then, archaeological research and restoration works have been carried out at and around the tell by various international teams and in co-operation with local specialists, and many areas remain off-limits to visitors due to the danger of unstable walls and infrastructure. The government plans to have 50 families live in the citadel once it is renovated.

The only religious structure that currently survives in the citadel is the Mulla Effendi mosque. When it was fully occupied, the citadel was divided in three districts or mahallas: from east to west the Serai, the Takya and the Topkhana. The Serai was occupied by notable families; the Takya district was named after the homes of dervishes, which are called takyas; and the Topkhana district housed craftsmen and farmers. Other sights to visit in the citadel include the bathing rooms (hammam) built in 1775 located near the mosque and the Textile Museum. Erbil citadel has been inscribed on the World Heritage List on 21 June 2014.

Other sights

• The 36-metre-high (118-foot) Mudhafaria Minaret, situated in Minaret Park several blocks from the citadel, dates back to the late 12th century AD and the Governor of Erbil, in the reign of Saladin, Muzaffar Al-Din Abu Sa'eed Al-Kawkaboori (Gökböri), who had entered in the obedience of Saladin without war and married his sister. It has an octagonal base decorated with two tiers of niches, which is separated from the main shaft by a small balcony, also decorated. Another historical minaret with turquoise glazed tiles is nearby.
• Khalidiya Khanqah Mosque and Tekke, a historic mosque and Sufi lodge founded in 1805 by Mawlana Khalid al-Naqshbandi.
• Sami Abdul Rahman Park
• The Mound of Qalich Agha lies within the grounds of the Museum of Civilization, 1 kilometre (0.62 mi) from the citadel. An excavation in 1996 found tools from the Halaf, Ubaid and Uruk periods.
• Classical School of the Medes

Sports

The local major football team is Erbil Soccer Club which plays its football matches at Franso Hariri Stadium (named after the assassinated Assyrian politician, former governor of Erbil city Franso Hariri) which is based in the south part of central Erbil. They won 3 Iraqi nation league titles and reached the AFC Final twice, but lost both times.

Demographics

The city is predominantly Kurdish and has minorities of local Turkmen, Chaldeans and Assyrians, as well as Arabs.

Turkmens

Although there are no official statistics on the number of Turkmens living in Erbil city, Turkmen community leaders claim that between 100,000 and 400,000 Turkmens reside in the Erbil Governorate. In the city itself they mainly reside in the neighbourhoods of Taci, Mareke and Three Tak in Erbil's city centre, around the citadel. Until 2006, they were living in the Tophane, Tekke and Saray neighborhoods of the Citadel, which contained almost 700 houses. In 2006, the citadel was emptied, and the Turkmen in the citadel were relocated to other neighbourhoods.

Iraq's first two Turkmen schools were opened on 17 November 1993, one in Erbil and the other in Kifri.

Erbil's citadel also contains the Turkmen Culture House.

Assyrians

Erbil's Ankawa district is mainly populated by Christian Assyrians. The district houses approximately 40 churches.

IDPs

In wake of the war against the Islamic State, millions of Iraq's Internally displaced people (IDPs) fled into the Kurdish region to find protection. At one point the city housed about 118,000 IDPs and 200,000 other refugees (mainly from Syria). However, after 2016 the numbers began to decline and the total now hovers around 230,000.

Economy

Agriculture has been a significant economic sector in Erbil in the past. Today, through its architectural heritage, ancient sites, traditional bazaars, historical mosques, and modern cultural centers, tourism forms a major part of Erbil's economy, besides its big oil and gas industry. In recent years, foreign and domestic investments in infrastructure, hotels, and entertainment facilities have further strengthened Erbil's position as a growing tourist destination in the Kurdistan Region and Iraq.

Erbil 2050 Master Plan

Between 2007 and 2009, the General Directorate of Urban Planning (GDUP) in the Ministry of Municipalities and Tourism (MoMT) developed the Erbil Master Plan. Over the years, investments from Turkey and the Gulf countries led to accelerated urban sprawl and an unexpected population increase, which made the original plan unsustainable. To address this, the GDUP partnered with the Japan International Cooperation Agency to develop a new approach with a planning horizon extending to 2050. JICA delivered its final proposal for the updated plan in October 2024.

Green Belt Project

The Erbil Green Belt Project is a large-scale macro-engineering project, launched in October 2025, designed to encircle the city with a protective green zone composed of trees and other vegetation. The project aims to combat deforestation, mitigate climate change and its impacts, improve the urban environment, and enhance residents' quality of life, while also providing employment opportunities and economic stimulus.

The Kurdish region initiative comes amid broader regional trends, as many Middle Eastern nations embark on large-scale environmental projects. Saudi Arabia's Middle East Green Initiative aims to plant 50 billion trees across the region, while the United Arab Emirates has committed to reaching net-zero carbon emissions by 2050. The Kurdish region efforts signal an unusually ambitious program within Iraq, as the Federal government in Baghdad has often struggled to advance nationwide afforestation and climate projects. The project is part of the broader Erbil Master Plan, which aims to guide the development and reorganization of Erbil city until 2050 in cooperation with the Japan International Cooperation Agency.

The project was officially inaugurated on 30 October 2025 by Kurdish Regional Government (KRG) Prime Minister Masrour Barzani.
