Bosporus Strait, the boundary between Europe and Asia. It is considered the country's economic, cultural and historic capital. The city has a population of over 15 million residents, comprising 19% of the population of Turkey,[3] and is the most populous city in Europe[c] and the world's fifteenth-largest city

The city was founded as

Latin: Nova Roma)[10] and then finally as Constantinople (Constantinopolis) after himself.[10][11] In 1930, the city's name was officially changed to Istanbul, the Turkish rendering of εἰς τὴν Πόλιν eis tḕn Pólin 'to the City', the appellation Greek speakers used since the 11th century to colloquially refer to the city.[10]

The city served as an imperial capital for almost 1600 years: during the Byzantine (330–1204), Latin (1204–1261), late Byzantine (1261–1453), and Ottoman (1453–1922) empires.[12] The city grew in size and influence, eventually becoming a beacon of the Silk Road and one of the most important cities in history. The city played a key role in the advancement of Christianity during Roman/Byzantine times, hosting four of the first seven ecumenical councils before its transformation to an Islamic stronghold following the Fall of Constantinople in 1453 CE—especially after becoming the seat of the Ottoman Caliphate in 1517.[13] In 1923, after the Turkish War of Independence, Ankara replaced the city as the capital of the newly formed Republic of Turkey.

Istanbul was the 2010

UNESCO World Heritage Site, and the city hosts the headquarters of numerous Turkish companies, accounting for more than thirty percent of the country's economy.[15][16]

The first known name of the city is

Ottoman Turkish: قسطنطينيه) and İstanbul were the names used alternatively by the Ottomans during their rule.[20]

The name İstanbul (Turkish pronunciation:

Ottoman Turkish: اسلامبول) on coinage was in 1730 during the reign of Sultan Mahmud I.[23] In modern Turkish, the name is written as İstanbul, with a dotted İ, as the Turkish alphabet distinguishes between a dotted and dotless I. In English the stress is on the first or last syllable, but in Turkish it is on the second syllable (-tan-).[24] A person from the city is an İstanbullu (plural İstanbullular); Istanbulite is used in English.[25]

Copper Age period, with artifacts dating from 5500 to 3500 BCE,[30] On the European side, near the point of the peninsula (Sarayburnu), there was a Thracian settlement during the early 1st millennium BCE. Modern authors have linked it to the Thracian toponym Lygos,[31] mentioned by Pliny the Elder as an earlier name for the site of Byzantium.[32]

The history of the city proper begins around 660 BCE,[10][33][e] when Greek settlers from Megara established Byzantium on the European side of the Bosporus. The settlers built an acropolis adjacent to the Golden Horn on the site of the early Thracian settlements, fueling the nascent city's economy.[39] The city experienced a brief period of Persian rule at the turn of the 5th century BCE, but the Greeks recaptured it during the Greco-Persian Wars.[40] Byzantium then continued as part of the Athenian League and its successor, the Second Athenian League, before gaining independence in 355 BCE.[41] Long allied with the Romans, Byzantium officially became a part of the Roman Empire in 73 CE.[42] Byzantium's decision to side with the Roman usurper Pescennius Niger against Emperor Septimius Severus cost it dearly; by the time it surrendered at the end of 195 CE, two years of siege had left the city devastated.[43] Five years later, Severus began to rebuild Byzantium, and the city regained—and, by some accounts, surpassed—its previous prosperity.[44]

Byzantine era

Originally built by Constantine the Great in the 4th century and later rebuilt by Justinian I after the Nika riots in 532, the Hagia Irene is an Eastern Orthodox Church located in the outer courtyard of Topkapı Palace in Istanbul. It is one of the few Byzantine era churches that were never converted into mosques; during the Ottoman period it served as Topkapı's principal armoury.
Originally a church, later a mosque, the 6th-century Hagia Sophia (532–537) by Byzantine emperor Justinian I was the largest cathedral in the world for nearly a thousand years, until the completion of the Seville Cathedral (1507) in Spain.

Constantine the Great effectively became the emperor of the whole of the Roman Empire in September 324.[45] Two months later, he laid out the plans for a new, Christian city to replace Byzantium. As the eastern capital of the empire, the city was named Nova Roma; most called it Constantinople, a name that persisted into the 20th century.[46] On 11 May 330, Constantinople was proclaimed the capital of the Roman Empire, which was later permanently divided between the two sons of Theodosius I upon his death on 17 January 395, when the city became the capital of the empire; during the following millennium of Roman history the state is commonly referred to as the "Byzantine Empire".[47]

The establishment of Constantinople was one of Constantine's most lasting accomplishments, shifting Roman power eastward as the city became a center of Greek culture and Christianity.

Christian civilization".[54][55]

Constantinople began to decline continuously after the end of the reign of Basil II in 1025. The Fourth Crusade was diverted from its purpose in 1204, and the city was sacked and pillaged by the crusaders.[56] They established the Latin Empire in place of the Orthodox Byzantine Empire.[57] Hagia Sophia was converted to a Catholic church in 1204. The Byzantine Empire was restored, albeit weakened, in 1261.[58] Constantinople's churches, defenses, and basic services were in disrepair,[59] and its population had dwindled to a hundred thousand from half a million during the 8th century.[f] After the reconquest of 1261, however, some of the city's monuments were restored, and some, like the two Deesis mosaics in Hagia Sophia and Kariye, were created.[60]

The 6th century Basilica Cistern was built by Justinian the Great.

Various economic and military policies instituted by Andronikos II Palaiologos, such as the reduction of military forces, weakened the empire and left it vulnerable to attack.[61] In the mid-14th-century, the Ottoman Turks began a strategy of gradually taking smaller towns and cities, cutting off Constantinople's supply routes and strangling it slowly.[62] On 29 May 1453, after an eight-week siege during which the last Roman emperor, Constantine XI, was killed, Sultan Mehmed II "the Conqueror" captured Constantinople.

Ottoman Empire

Sultan Mehmed declared Constantinople the new capital of the

Kayser-i Rûm, the Ottoman Turkish equivalent of the Caesar of Rome, and the Ottoman state was reorganized into an empire.[64][65]

Following the capture of Constantinople, Mehmed II immediately set out to revitalize the city. Cognizant that revitalization would fail without the repopulation of the city,

aqueducts.[68] Like many monarchs before and since, Mehmed II transformed Istanbul's urban landscape with wholesale redevelopment of the city center.[69] There was a huge new palace to rival, if not overshadow, the old one, a new covered market (still standing as the Grand Bazaar), porticoes, pavilions, walkways, as well as more than a dozen new mosques.[68] Mehmed II turned the ramshackle old town into something that looked like an imperial capital.[69]

Social hierarchy was ignored by the rampant plague, which killed the rich and the poor alike in the 16th century.[70] Money could not protect the rich from all the discomforts and harsher sides of Istanbul.[70] Although the Sultan lived at a safe remove from the masses, and the wealthy and poor tended to live side by side, for the most part Istanbul was not zoned as modern cities are.[70] Opulent houses shared the same streets and districts with tiny hovels.[70] Those rich enough to have secluded country properties had a chance of escaping the periodic epidemics of sickness that blighted Istanbul.[70]

ceramics, stained glass, calligraphy, and miniature flourished.[71] The population of Constantinople was 570,000 by the end of the 18th century.[72]

A period of rebellion at the start of the 19th century led to the rise of the progressive Sultan

Cadde-i Kebir in 1912 (present-day İstiklal Avenue in Beyoğlu). The entrance of the Church of St. Anthony of Padua is seen at left. A Nestlé advertisement is visible on a building in the background.

With the Young Turk Revolution in 1908, the Ottoman Parliament, closed since 14 February 1878, was reopened 30 years later on 23 July 1908, which marked the beginning of the Second Constitutional Era.[78] The civil strife and political uncertainties in the Ottoman Empire during the months after the revolution encouraged Austria-Hungary to annex Bosnia and Bulgaria to declare its independence in a jointly coordinated move on 5 October 1908. Sultan Abdul Hamid II was deposed in 1909, following the counter-revolution attempt known as the 31 March incident. A series of wars in the early 20th century, such as the Italo-Turkish War (1911–1912) and the Balkan Wars (1912–1913), plagued the ailing empire's capital and resulted in the 1913 Ottoman coup d'état, which brought the regime of the Three Pashas.[79]

The Ottoman Empire joined

occupied Constantinople on 13 November 1918. The Ottoman Parliament was dissolved by the Allies on 11 April 1920 and the Ottoman delegation led by Damat Ferid Pasha was forced to sign the Treaty of Sèvres on 10 August 1920.[citation needed

Following the Turkish War of Independence (1919–1922), the Grand National Assembly of Turkey in Ankara abolished the Sultanate on 1 November 1922, and the last Ottoman Sultan, Mehmed VI, was declared persona non grata. Leaving aboard the British warship HMS Malaya on 17 November 1922, he went into exile and died in Sanremo, Italy, on 16 May 1926.

The Treaty of Lausanne was signed on 24 July 1923, and the occupation of Constantinople ended with the departure of the last forces of the Allies from the city on 4 October 1923.[83] Turkish forces of the Ankara government, commanded by Şükrü Naili Pasha (3rd Corps), entered the city with a ceremony on 6 October 1923, which has been marked as the "Liberation Day of Istanbul" (İstanbul'un Kurtuluşu), and has been commemorated annually since.[83]

Turkish Republic

On 29 October 1923 the Grand National Assembly of Turkey declared the establishment of the Turkish Republic, with Ankara as its capital. Mustafa Kemal Atatürk became the Republic's first President.[84][85]

A 1942 wealth tax assessed mainly on non-Muslims led to the transfer or liquidation of many businesses owned by religious minorities.[86] From the late 1940s and early 1950s, Istanbul underwent great structural change, as new public squares, boulevards, and avenues were constructed throughout the city, sometimes at the expense of historical buildings.[87] The population of Istanbul began to rapidly increase in the 1970s, as people from Anatolia migrated to the city to find employment in the many new factories that were built on the outskirts of the sprawling metropolis. This sudden, sharp rise in the city's population caused a large demand for housing, and many previously outlying villages and forests became engulfed into the metropolitan area of Istanbul.[88]

Geography and environment

Satellite view of Istanbul and the Bosporus

Istanbul is in north-western Turkey and straddles the

Bosporus Strait, which provides the only passage from the Black Sea to the Mediterranean via the Sea of Marmara.[15] Historically, the city has been ideally situated for trade and defense: The confluence of the Sea of Marmara, the Bosporus, and the Golden Horn provide both ideal defense against enemy attack and a natural toll-gate.[15] Several picturesque islands—Büyükada, Heybeliada, Burgazada, Kınalıada, and five smaller islands—are part of the city.[15] Istanbul's shoreline has grown beyond its natural limits. Large sections of Caddebostan sit on areas of landfill, increasing the total area of the city to 5,343 square kilometers (2,063 sq mi).[15]

Despite the myth that seven hills make up the city, there are, in fact, more than 50 hills within the city limits. Istanbul's tallest hill, Aydos, is 537 meters (1,762 ft) high.[15]

The threat of major earthquakes plays a large role in the city's infrastructure development, with over 500,000 vulnerable buildings demolished and replaced since 2012.

buildings in Istanbul were built to a low seismic standard in the 20th century,[98] and residents think the city is not properly prepared for the earthquake.[99]


Şile and Kilyos are two seaside resorts on the Black Sea, the body of water which tempers Istanbul's climate.

Istanbul's climate is temperate, and is often described as transitional between the Mediterranean climate typical of the western and southern coasts of Turkey, and the oceanic climate of the northwestern coasts of the country.[100] Much divergence exists in the terminology used to classify the city's climate, however.

The city's summers are warm to hot and moderately dry, with an average daytime temperature of about 28 °C (82 °F), and less than 7 days of precipitation per month. Despite the generally acceptable temperature range, mid-summer in Istanbul is considered moderately uncomfortable, due to high dew points and relative humidity.[101] Winters, meanwhile, are cool, quite rainy, and relatively snow-rich for a city with above-freezing average temperatures.

Istanbul's precipitation is unevenly distributed, with winter months getting at least twice the level of precipitation of their summerly counterparts. The mode of precipitation also varies by season. Winter precipitation is generally light, persistent and often of mixed precipitation such as rain-snow mixes and graupel; while summer precipitation is generally abrupt and sporadic. Cloudiness, as with precipitation, varies greatly by season. Winters are quite cloudy, with around 20 percent of days being sunny or partly cloudy. Meanwhile, summers experience 60-70 percent of possible sunshine.

Snowfall is sporadic, but accumulates virtually every winter; and when it does, it is highly disruptive to city infrastructure. Sea-effect snowstorms with more than 30 centimetres (1 ft) of snowfall happen almost annually, most recently in 2022.[102][103]

Climate change

Müze Gazhane in Kadıköy is the first climate change museum in Turkey.

Climate change has caused an increase in Istanbul's heatwaves,[107] droughts,[108] storms,[109] and flooding[110][111] in Istanbul. Furthermore, as Istanbul is a large and rapidly expanding city, its urban heat island has been intensifying the effects of climate change.[112] If trends continue, sea level rise is likely to affect city infrastructure, for example Kadıkoy metro station is threatened with flooding.[113] Xeriscaping of green spaces has been suggested,[114] and Istanbul has a climate-change action plan,[115] but not a net zero target.[116]: 51 

Flora and fauna

Belgrad Forest is a mixed broadleaf forest to the north of Istanbul.

The natural vegetation of the province is made up of

acclimatized to Istanbul.[117] In a study that examined urban flora in Kartal, a total of 576 plant taxa were recorded; of those 477 were natural and 99 were exotic and cultivated. The most prominent native taxa were in the Asteraceae family (50 species), while the most diverse exotic plant family was Rosaceae (16 species).[118]

short-beaked common dolphin (Turkish: tırtak) and harbor porpoise (Turkish: mutur) make up the marine mammals presently found in the Bosporus and surrounding waters, though since the 1950s the number of dolphin observations has become increasingly rare. Mediterranean monk seals were present in Bosporus, and Princes' Islands and Tuzla shores were seal breeding areas during summer, but they have not been observed in Istanbul since the 1960s and thought to be extinct in the region.[121] Water pollution, overfishing
and destruction of coastal habitats caused by urbanization are main threats to Istanbul's marine ecology.

Street cats in the city

Apart from the wild land mammals Istanbul hosts a sizeable

stray animal population. The presence of feral cats in Istanbul (Turkish: sokak kedisi) is noted to be very prevalent, with estimates ranging from a hundred thousand to over a million stray cats. The feral cats in the city have gained widespread media and public attention and are considered to be symbols of the city.[122][123] Rose-ringed parakeet colonies are present in urban areas, similar to other European cities as feral parrots, and considered as invasive species.[124]

red tides were reported in the Sea of Marmara and Bosporus (especially in Golden Horn), and regularly happen in urban lakes such as Lake Büyükçekmece and Küçükçekmece. In June 2021, a marine mucilage wave allegedly caused by water pollution spread to Sea of Marmara.[130]


Districts and neighborhoods

European side

Fatih district comprises the historical peninsula of Istanbul

The Fatih district, which was named after Mehmed II (Turkish: Fatih Sultan Mehmed), corresponds to what was the whole of Constantinople until the Ottoman conquest; today it is the capital district and called the historic peninsula of Istanbul on the southern shore of the Golden Horn, across the medieval Genoese citadel of Galata on the northern shore. The Genoese fortifications in Galata were largely demolished in the 19th century, leaving only the Galata Tower, to make way for the northward expansion of the city.[131] Galata (Karaköy) is today a quarter within the Beyoğlu district, which forms Istanbul's commercial and entertainment center and includes İstiklal Avenue and Taksim Square.[132]

Originally outside the city, yalı residences along the Bosporus are now homes in some of Istanbul's elite neighborhoods.

Bomonti are important nodes within the CBD.[134][135]

The Atatürk Airport corridor is another such edge city-style business, residential and shopping corridor with over 900,000 m2 (9,700,000 sq ft) of class-A office space.[135]

As a result of Istanbul's exponential growth in the 20th century, a significant portion of the city is composed of gecekondus (literally "built overnight"), referring to illegally constructed squatter buildings.[137] At present, some gecekondu areas are being gradually demolished and replaced by modern mass-housing compounds.[138] Moreover, large scale gentrification and urban renewal projects have been taking place,[139] such as the one in Tarlabaşı;[140] some of these projects, like the one in Sulukule, have faced criticism.[141] The Turkish government also has ambitious plans for an expansion of the city west and northwards on the European side in conjunction with the new Istanbul Airport, opened in 2019; the new parts of the city will include four different settlements with specified urban functions, housing 1.5 million people.[142]


Yıldız Park connects Yıldız Palace to Çırağan Palace

Istanbul does not have a primary urban park, but it has several green areas. Gülhane Park and Yıldız Park were originally included within the grounds of two of Istanbul's palaces — Topkapı Palace and Yıldız Palace—but they were repurposed as public parks in the early decades of the Turkish Republic.[143] Another park, Fethi Paşa Korusu, is on a hillside adjacent to the Bosphorus Bridge in Anatolia, opposite Yıldız Palace in Europe.

Along the European side, and close to the

Isma'il Pasha of Ottoman Egypt in the 19th century. Emirgan Park is known for its diversity of plants and an annual tulip festival is held there since 2005.[144]


Taksim Gezi Park with a replica of the Ottoman era Taksim Military Barracks (which was transformed into the Taksim Stadium in 1921, before being demolished in 1940 for building Gezi Park) sparked a series of nationwide protests in 2013
covering a wide range of issues.

Popular during the summer among Istanbulites is Belgrad Forest, spreading across 5,500 hectares (14,000 acres) at the northern edge of the city. The forest originally supplied water to the city and remnants of reservoirs used during Byzantine and Ottoman times survive.[145][146]

Istanbul is primarily known for its Byzantine and Ottoman architecture. Despite its development as a Turkish city since 1923, it contains many ancient, Roman, Byzantine, Christian, Muslim, and Jewish monuments.

The Neolithic settlement in the Yenikapı quarter on the European side, which dates back to c. 6500 BCE and predates the formation of the Bosporus by approximately a millennium, when the Sea of Marmara was still a lake,[citation needed] was discovered during the construction of the Marmaray railway tunnel.[26] It is the oldest known human settlement on the European side of the city.[26] The oldest known human settlement on the Asian side is the Fikirtepe Mound near Kadıköy, with relics dating to the Chalcolithic period c. 5500 – c. 3500 BCE.

There are numerous ancient monuments in the city.

spina of the Circus Maximus in Rome in the autumn of that year, and is now known as the Lateran Obelisk. The obelisk that would become the Obelisk of Theodosius remained in Alexandria until 390, when Theodosius I (r. 379–395) had it transported to Constantinople and put up on the spina of the Hippodrome there.[148] When re-erected at the Hippodrome of Constantinople, the obelisk was mounted on a decorative base, with reliefs that depict Theodosius I and his courtiers.[147] The lower part of the obelisk was damaged in antiquity, probably during its transport to Alexandria in 357 CE or during its re-erection at the Hippodrome of Constantinople in 390 CE. As a result, the current height of the obelisk is only 18.54 meters, or 25.6 meters if the base is included. Between the four corners of the obelisk and the pedestal are four bronze cubes, used in its transportation and re-erection.[149]

Abdülaziz, the 19th-century Dolmabahçe, Çırağan, Beylerbeyi and Küçüksu palaces on the Bosporus were designed by members of the Armenian Balyan family of court architects.[150]

Next in age is the

Persian Empire at the Battle of Plataea in 479 BCE. The three serpent heads of the 8-meter (26 ft) high column remained intact until the end of the 17th century (one is on display at the nearby Istanbul Archaeology Museums).[151]

Manuel Komnenos (r. 1143–1180).[17][147]

There are traces of the Byzantine era throughout the city, from ancient churches that were built over early Christian meeting places like the

Porta Aurea (Golden Gate), among numerous others. The 4th century Harbor of Theodosius in Yenikapı, once the busiest port in Constantinople, was among the numerous archeological discoveries that took place during the excavations of the Marmaray tunnel.[26]

However, it is the Hagia Sophia that fully conveys the period of Constantinople as a city without parallel in Christendom. The Hagia Sophia, topped by a dome 31 meters (102 ft) in diameter over a square space defined by four arches, is the pinnacle of Byzantine architecture.[152] The Hagia Sophia stood as the world's largest cathedral in the world until it was converted into a mosque in the 15th century.[152] The minarets date from that period.[152] Because of its historical significance, it was reopened as a museum in 1935. However, it was re-converted into a mosque in July 2020.

) is seen in the foreground.

Over the next four centuries, the Ottomans transformed Istanbul's urban landscape with a vast building scheme that included the construction of towering mosques and ornate palaces. The

Sultan Ahmed Mosque (Blue Mosque), another landmark of the city, faces the Hagia Sophia at Sultanahmet Square (Hippodrome of Constantinople). The Süleymaniye Mosque, built by Suleiman the Magnificent, was designed by his chief architect Mimar Sinan, the most illustrious of all Ottoman architects, who designed many of the city's renowned mosques and other types of public buildings and monuments.[154]

Among the oldest surviving examples of Ottoman architecture in Istanbul are the Anadoluhisarı and Rumelihisarı fortresses, which assisted the Ottomans during their siege of the city.[155] Over the next four centuries, the Ottomans made an indelible impression on the skyline of Istanbul, building towering mosques and ornate palaces.

Topkapı Palace, dating back to 1465, is the oldest seat of government surviving in Istanbul. Mehmed II built the original palace as his main residence and the seat of government.

Baghdad Kiosk, to commemorate his conquest of Baghdad the previous year.[158] Government meetings took place here until 1786, when the seat of government was moved to the Sublime Porte.[156] After several hundred years of royal residence, it was abandoned in 1853 in favor of the baroque Dolmabahçe Palace.[157] Topkapı Palace became public property following the abolition of monarchy in 1922.[157] After extensive renovation, it became one of Turkey's first national museums in 1924.[156]


Yeni Mosque, all of which were built at the peak of the Ottoman Empire, in the 16th and 17th centuries. In the following centuries, and especially after the Tanzimat reforms, Ottoman architecture was supplanted by European styles.[159] An example of which is the imperial Nuruosmaniye Mosque. Areas around İstiklal Avenue were filled with grand European embassies and rows of buildings in Neoclassical, Renaissance Revival and Art Nouveau styles, which went on to influence the architecture of a variety of structures in Beyoğlu—including churches, stores, and theaters—and official buildings such as Dolmabahçe Palace.[160]


Since 2004, the municipal boundaries of Istanbul have been coincident with the boundaries of its province.[161] The city, considered capital of the larger Istanbul Province, is administered by the Istanbul Metropolitan Municipality (IMM, Turkish: İstanbul Büyükşehir Belediyesi, IBB), which oversees the 39 districts of the city-province.

The current city structure can be traced back to the Tanzimat period of reform in the 19th century, before which

Ottoman constitution of 1876 aimed to expand this structure across the city, imitating the twenty arrondissements of Paris, but they were not fully implemented until 1908 when the city was declared a province with nine constituent districts.[163][164] This system continued beyond the founding of the Turkish Republic, with the province renamed a belediye (municipality), but the municipality was disbanded in 1957.[165]

Istanbul Province

Small settlements adjacent to major population centers in Turkey, including Istanbul, were merged into their respective primary cities during the early 1980s, resulting in metropolitan municipalities.[166][167] The main decision-making body of the Istanbul Metropolitan Municipality is the Municipal Council, with members drawn from district councils.

The Municipal Council of Istanbul is responsible for citywide issues, including managing the budget, maintaining civic infrastructure, and overseeing museums and major cultural centers.[168] Since the government operates under a "powerful mayor, weak council" approach, the council's leader—the metropolitan mayor—has the authority to make swift decisions, often at the expense of transparency.[169] The Municipal Council is advised by the Metropolitan Executive Committee, although the committee also has limited power to make decisions of its own.[170] All representatives on the committee are appointed by the metropolitan mayor and the council, with the mayor—or someone of his or her choosing—serving as head.[170][171]

District councils are chiefly responsible for waste management and construction projects within their respective districts. They each maintain their own budgets, although the metropolitan mayor reserves the right to review district decisions. One-fifth of all district council members, including the district mayors, also represent their districts in the Municipal Council.[168] All members of the district councils and the Municipal Council, including the metropolitan mayor, are elected to five-year terms.[172] Representing the Republican People's Party, Ekrem İmamoğlu has been the Mayor of Istanbul since 27 June 2019.[173]

With the Istanbul Metropolitan Municipality and Istanbul Province having equivalent jurisdictions, few responsibilities remain for the provincial government. Like the MMI, the Istanbul Special Provincial Administration has a governor, a democratically elected decision-making body—the Provincial Parliament—and an appointed Executive Committee. Mirroring the executive committee at the municipal level, the Provincial Executive Committee includes a secretary-general and leaders of departments that advise the Provincial Parliament.

Pre-Republic figures estimated[f]

Throughout most of its history, Istanbul has ranked among the largest cities in the world. By 500 CE, Constantinople had somewhere between 400,000 and 500,000 people, edging out its predecessor, Rome, for the world's largest city.[179] Constantinople jostled with other major historical cities, such as Baghdad, Chang'an, Kaifeng and Merv for the position of the world's largest city until the 12th century. It never returned to being the world's largest, but remained the largest city in Europe from 1500 to 1750, when it was surpassed by London.[180]

The Turkish Statistical Institute estimates that the population of Istanbul Metropolitan Municipality was 15,519,267 at the end of 2019, hosting 19 percent of the country's population.[181] 64.4% of the residents live on the European side and 35.6% on the Asian side.[181]

Istanbul ranks as the

Organisation for Economic Co-operation and Development. The high population growth mirrors an urbanization trend across the country, as the second and third fastest-growing OECD metropolises are the Turkish cities of İzmir and Ankara.[16]

Istanbul experienced especially rapid growth during the second half of the 20th century, with its population increasing tenfold between 1950 and 2000.[184] This growth was fueled by internal and international migration. Istanbul's foreign population with a residence permit increased dramatically, from 43,000 in 2007[185] to 856,377 in 2019.[186][187]

According to 2020 TÜİK data around 2.1 million people in a population of over 15.4 million have been registered[g] in Istanbul, meanwhile the vast majority of the residents ultimately originate from Anatolian provinces, especially those in the Black Sea, Central and Eastern Anatolia regions due to internal migration since the 1950s.[188] People registered in Kastamonu, Ordu, Giresun, Erzurum, Samsun, Malatya, Trabzon, Sinop and Rize provinces represent the biggest population groups in Istanbul, meanwhile people registered in Sivas has the highest percentage with more than 760 thousand residents in the city.[189] A 2019 survey found that only 36% of the Istanbul's population was born in the province.[190]

Ethnic and religious groups

Ethnic groups among Turkish citizens in Istanbul (2019 KONDA survey)

Istanbul has been a cosmopolitan city throughout much of its history, but it has become more homogenized since the end of the Ottoman era. The dominant ethnic group in the city is Turkish people, which also forms the majority group in Turkey. According to survey data 78% of the voting-age Turkish citizens in Istanbul state "Turkish" as their ethnic identity.[190]

With estimates ranging from 2 to 4 million, Kurds form one of the largest ethnic minorities in Istanbul and are the biggest group after Turks among Turkish citizens.[191][192] According to a 2019 KONDA study, Kurds constituted around 17% of Istanbul's adult total population who were Turkish citizens.[190] Although the initial Kurdish presence in the city dates back to the early Ottoman period,[193] the majority of Kurds in the city originate from villages in eastern and southeastern Turkey.[194] Zazas are also present in the city and constitute around 1% of the total voting-age population.[190]

refugees of the Syrian Civil War in Turkey residing in Istanbul was estimated to be around 1 million.[199] Native Arab population in Turkey who are Turkish citizens are found to be making up less than 1% of city's total adult population.[190] As of August 2023, there were more than 530,000 refugees of the Syrian civil war in Istanbul, the highest number in any Turkish city.[200]

Built by Suleiman the Magnificent, the Süleymaniye Mosque (1550–1557) was designed by his chief architect Mimar Sinan, the most illustrious of all Ottoman architects.[154]

A 2019 survey study by KONDA that examined the religiosity of the voting-age adults in Istanbul showed that 57% of the surveyed had a religion and were trying to practise its requirements. This was followed by nonobservant people with 26% who identified with a religion but generally did not practise its requirements. 11% stated they were fully devoted to their religion, meanwhile 6% were

Sunni Muslims and Alevism forms the second biggest religious group.[190][201]

Into the 19th century, the Christians of Istanbul tended to be either

thousands to leave.[203] Following Greek migration to the city for work in the 2010s, the Greek population rose to nearly 3,000 in 2019, still greatly diminished since 1919, when it stood at 350,000.[203] There are today 50,000 to 70,000 Armenians in Istanbul[204] down from a peak of 164,000 in 1913.[205] As of 2019, an estimated 18,000 of the country's 25,000 Christian Assyrians live in Istanbul.[206]

There are 234 active churches and chapels in the city,[207] including the Church of St. Anthony of Padua on İstiklal Avenue in Beyoğlu (Pera).

The majority of the Catholic Levantines (Turkish: Levanten) in Istanbul and İzmir are the descendants of traders/colonists from the Italian maritime republics of the Mediterranean (especially Genoa and Venice) and France, who obtained special rights and privileges called the Capitulations from the Ottoman sultans in the 16th century.[208] The community had more than 15,000 members during Atatürk's presidency in the 1920s and 1930s, but today is reduced to only a few hundreds, according to Italo-Levantine writer Giovanni Scognamillo.[209] They continue to live in Istanbul (mostly in Karaköy, Beyoğlu and Nişantaşı), and İzmir (mostly in Karşıyaka, Bornova and Buca).

Istanbul became one of the world's most important Jewish centers in the 16th and 17th century.

Jews in Europe, Ottoman Jews were allowed to work in any profession.[211] Ottoman Jews in Istanbul excelled in commerce and came to particularly dominate the medical profession.[211] By 1711, using the printing press, books came to be published in Spanish and Ladino, Yiddish, and Hebrew.[212] In large part due to emigration to Israel, the Jewish population in the city dropped from 100,000 in 1950[213] to 15,000 in 2021.[214][215][216]


Politically, Istanbul is seen as the most important administrative region in Turkey. In the run-up to local elections in 2019, Erdoğan claimed 'if we fail in Istanbul, we will fail in Turkey'.[217] The contest in Istanbul carried deep political, economic and symbolic significance for Erdoğan, whose election of mayor of Istanbul in 1994 had served as his launchpad.[218] For Ekrem İmamoğlu, winning the mayoralty of Istanbul was a huge moral victory, but for Erdoğan it had practical ramifications: His party, AKP, lost control of the $4.8 billion municipal budget, which had sustained patronage at the point of delivery of many public services for 25 years.[219]


More recently, Istanbul and many of Turkey's metropolitan cities are following a trend away from the government and their right-wing ideology. In 2013 and 2014, large scale

Supreme Electoral Council due to AKP's claim of electoral fraud. In the re-run İmamoğlu gathered 54.22% of the total vote and widened his margin of victory.[220]

Following the 2019 election, a trend towards the CHP has persisted across the city. In the 2023 presidential election the CHP candidate, Kemal Kılıçdaroğlu, received 48.56% of the city's vote, while the incumbent president and AKP candidate, Recep Tayyip Erdoğan, received 46.68%.

In the 2024 local elections, Ekrem İmamoğlu was re-elected by a 12-point margin. İmamoğlu won 51.15% of the vote, while the AKP's candidate Murat Kurum received 39.59%. Additionally, the CHP won the mayoralties in 26 of İstanbul's 39 districts.[221]

Administratively, Istanbul is divided into 39 districts, more than any other

one on the Asian side, electing 28, 35 and 35 MPs respectively.[citation needed

Istanbul had the eleventh-largest economy among the world's urban areas in 2018, and is responsible for 30 percent of Turkey's industrial output,[222] 31 percent of GDP,[222] and 47 percent of tax revenues.[222] The city's gross domestic product adjusted by PPP stood at US$537.507 billion in 2018,[223] with manufacturing and services accounting for 36 percent and 60 percent of the economic output respectively.[222] Istanbul's productivity is 110 percent higher than the national average.[222] Trade is economically important, accounting for 30 percent of the economic output in the city.[15] In 2019, companies based in Istanbul produced exports worth $83.66 billion and received imports totaling $128.34 billion; these figures were equivalent to 47 percent and 61 percent, respectively, of the national totals.[224]

Istanbul, which straddles the Bosporus strait, houses international ports that link Europe and Asia. The Bosporus, providing the only passage from the Black Sea to the Mediterranean, is the world's busiest and narrowest strait used for international navigation, with more than 200 million tons of oil passing through it each year.

Shipping is a significant part of the city's economy, with 73.9 percent of exports and 92.7 percent of imports in 2018 executed by sea.[15] Istanbul has three major shipping ports – the Port of Haydarpaşa, the Port of Ambarlı, and the Port of Zeytinburnu – as well as several smaller ports and oil terminals along the Bosporus and the Sea of Marmara.[15]

Haydarpaşa, at the southeastern end of the Bosporus, was Istanbul's largest port until the early 2000s.[227] Since then operations were shifted to Ambarlı, with plans to convert Haydarpaşa into a tourism complex.[15] In 2019, Ambarlı, on the western edge of the urban center, had an annual capacity of 3,104,882 TEUs, making it the third-largest cargo terminal in the Mediterranean basin.[227]

Istanbul has been an international banking hub since the 1980s,[15] and is home to the only active stock exchange in Turkey, Borsa Istanbul, which was originally established as the Ottoman Stock Exchange in 1866.[228]

Ottoman Central Bank Head Office (1892) on Bankalar Caddesi

In 1995, keeping up with the financial trends, Borsa Istanbul moved its headquarters (which was originally located on Bankalar Caddesi, the financial center of the Ottoman Empire,[228] and later at the 4th Vakıf Han building in Sirkeci) to İstinye, in the vicinity of Maslak, which hosts the headquarters of numerous Turkish banks.[229]

13.4 million foreign tourists visited the city in 2018, making Istanbul the world's fifth most-visited city in that year.[239] Istanbul and Antalya are Turkey's two largest international gateways, receiving a quarter of the nation's foreign tourists. Istanbul has more than fifty museums, with the Topkapı Palace, the most visited museum in the city, bringing in more than $30 million in revenue each year.[15]

Istanbul was historically known as a cultural hub, but its cultural scene stagnated after the Turkish Republic shifted its focus toward Ankara.[243] The new national government established programs that served to orient Turks toward musical traditions, especially those originating in Europe, but musical institutions and visits by foreign classical artists were primarily centered in the new capital.[244]

Much of Turkey's cultural scene had its roots in Istanbul, and by the 1980s and 1990s Istanbul reemerged globally as a city whose cultural significance is not solely based on its past glory.[245]

By the end of the 19th century, Istanbul had established itself as a regional artistic center, with Turkish, European, and Middle Eastern artists flocking to the city. Despite efforts to make Ankara Turkey's cultural heart, Istanbul had the country's primary institution of art until the 1970s.[246] When additional universities and art journals were founded in Istanbul during the 1980s, artists formerly based in Ankara moved in.[247]

Beyoğlu has been transformed into the artistic center of the city, with young artists and older Turkish artists formerly residing abroad finding footing there. Modern art museums, including

İstanbul Modern, the Pera Museum, Sakıp Sabancı Museum, Arter and SantralIstanbul, opened in the 2000s to complement the exhibition spaces and auction houses that have already contributed to the cosmopolitan nature of the city.[249] These museums have yet to attain the popularity of older museums on the historic peninsula, including the Istanbul Archaeology Museums, which ushered in the era of modern museums in Turkey, and the Turkish and Islamic Arts Museum.[248]

The restored Paket Postanesi (Parcel Post Office) building is now a symbol of Galataport. The district is also home to Museums Square.

The first film screening in Turkey was at Yıldız Palace in 1896, a year after the technology publicly debuted in Paris.[250] Movie theaters rapidly cropped up in Beyoğlu, with the greatest concentration of theaters being along the street now known as İstiklal Avenue.[251] Istanbul also became the heart of Turkey's nascent film industry, although Turkish films were not consistently developed until the 1950s.[252] Since then, Istanbul has been the most popular location to film Turkish dramas and comedies.[253] The Turkish film industry ramped up in the second half of the century, and with Uzak (2002) and My Father and My Son (2005), both filmed in Istanbul, the nation's movies began to see substantial international success.[254] Istanbul and its picturesque skyline have also served as a backdrop for several foreign films, including From Russia with Love (1963), Topkapi (1964), The World Is Not Enough (1999), and Mission Istaanbul (2008).[255]

Coinciding with this cultural reemergence was the establishment of the Istanbul Festival, which began showcasing a variety of art from Turkey and around the world in 1973. From this flagship festival came the International Istanbul Film Festival and the Istanbul Jazz Festival in the early 1980s. With its focus now solely on music and dance, the Istanbul Festival has been known as the Istanbul International Music Festival since 1994.[256] The most prominent of the festivals that evolved from the original Istanbul Festival is the Istanbul Biennial, held every two years since 1987. Its early incarnations were aimed at showcasing Turkish visual art, and it has since opened to international artists and risen in prestige to join the elite biennales, alongside the Venice Biennale and the São Paulo Art Biennial.[257]

Leisure and entertainment

İstiklal Avenue in Beyoğlu

Abdi İpekçi Street in Nişantaşı, Galataport Shopping Area in Karaköy and Bağdat Avenue on the Anatolian side of the city have evolved into high-end shopping districts.[258][259] Other focal points for shopping, leisure and entertainment include Nişantaşı, Ortaköy, Bebek and Kadıköy.[260] The city has numerous shopping centers, from the historic to the modern. Istanbul also has an active nightlife and historic taverns, a signature characteristic of the city for centuries, if not millennia.

The Grand Bazaar, in operation since 1461, is among the world's oldest and largest covered markets.[261][262] Mahmutpasha Bazaar is an open-air market extending between the Grand Bazaar and the Spice Bazaar, which has been Istanbul's major spice market since 1660.

Galleria Ataköy ushered in the age of modern shopping malls in Turkey when it opened in 1987.[263] Since then, malls have become major shopping centers outside the historic peninsula. Akmerkez was awarded the titles of "Europe's best" and "World's best" shopping mall by the International Council of Shopping Centers in 1995 and 1996; Istanbul Cevahir has been one of the continent's largest since opening in 2005; and Kanyon won the Cityscape Architectural Review Award in the Commercial Built category in 2006.[262] Zorlu Center and İstinye Park are among the other upscale malls in Istanbul which include the stores of the world's top fashion brands.

Süreyya Opera House is situated on the Asian side of Istanbul and Atatürk Cultural Center is the main opera house on the European side.

Along İstiklal Avenue is the Çiçek Pasajı ('Flower Passage'), a 19th-century shopping gallery which is today home to winehouses (known as meyhanes), pubs and restaurants.[264] İstiklal Avenue, originally known for its taverns, has shifted toward shopping, but the nearby Nevizade Street is still lined with winehouses and pubs.[265][266] Some other neighborhoods around İstiklal Avenue have been revamped to cater to Beyoğlu's nightlife, with formerly commercial streets now lined with pubs, cafes, and restaurants playing live music.[267]

Zorlu Center, designed by EAA and Tabanlıoğlu Architects, includes Zorlu PSM, the city's largest performing arts theatre and concert hall.

Istanbul is known for its historic seafood restaurants. Many of the city's most popular and upscale seafood restaurants line the shores of the Bosporus (particularly in neighborhoods like Ortaköy, Bebek, Arnavutköy, Yeniköy, Beylerbeyi and Çengelköy). Kumkapı along the Sea of Marmara has a pedestrian zone that hosts around fifty fish restaurants.[268]

The Princes' Islands, 15 kilometers (9 mi) from the city center, are also popular for their seafood restaurants. Because of their restaurants, historic summer mansions, and tranquil, car-free streets, the Princes' Islands are a popular vacation destination among Istanbulites and foreign tourists.[269]

Istanbul is also famous for its sophisticated and elaborately-cooked dishes of the Ottoman cuisine. Following the influx of immigrants from southeastern and eastern Turkey, which began in the 1960s, the city's foodscape has drastically changed by the end of the century; with influences of Middle Eastern cuisine such as kebab taking an important place in the food scene.

Restaurants featuring foreign cuisines are mainly concentrated in the Beyoğlu, Beşiktaş, Şişli and Kadıköy districts.

Apart from the city's numerous stadiums, sports halls and concert halls, there are several open-air venues for concerts and festivals, such as the Cemil Topuzlu Open-Air Theatre in Harbiye, Paraf Kuruçeşme Open-Air on the Bosphorus shore in Kuruçeşme, and Parkorman in the forest of Maslak. The annual Istanbul Jazz Festival has been held every year since 1994. Organized between 2003 and 2013, Rock'n Coke was the biggest open-air rock festival in Turkey, sponsored by Coca-Cola. It was traditionally held at the Hezarfen Airfield in Istanbul.

Abdi İpekçi Street in Nişantaşı, one of Istanbul's premier shopping streets

The Istanbul International Music Festival has been held annually since 1973, and the International Istanbul Film Festival has been held annually since 1982. The Istanbul Biennial is a contemporary art exhibition that has been held biennially since 1987. The Istanbul Shopping Fest is an annual shopping festival held since 2011, and Teknofest is an annual festival of aviation, aerospace and technology, held since 2018.

When it was held for the first time in 2003, the annual Istanbul Pride became the first gay pride event in a Muslim-majority country.[270] Since 2015, all types of parades at Taksim Square and İstiklal Avenue (where, in 2013, the Gezi Park protests took place) have been denied permission by the AKP government, citing security concerns, but hundreds of people have defied the ban each year. Critics have claimed that the bans were in fact due to ideological reasons.

Küçük Çamlıca TV Radio Tower (369 m (1,211 ft)) is the tallest structure in the city.[297]

Most state-run radio and television stations are based in Ankara, but Istanbul is the primary hub of Turkish media. The industry has its roots in the former Ottoman capital, where the first Turkish newspaper, Takvim-i Vekayi (Calendar of Affairs), was published in 1831. The Cağaloğlu street on which the newspaper was printed, Bâb-ı Âli Street, rapidly became the center of Turkish print media, alongside Beyoğlu across the Golden Horn.[298]

Istanbul now has a wide variety of periodicals. Most nationwide newspapers are based in Istanbul, with simultaneous Ankara and İzmir editions.[299] Hürriyet, Sabah, Posta and Sözcü, the country's top four papers, are all headquartered in Istanbul, boasting more than 275,000 weekly sales each.[300] Hürriyet's English-language edition, Hürriyet Daily News, has been printed since 1961, but the English-language Daily Sabah, first published by Sabah in 2014, has overtaken it in circulation. Several smaller newspapers, including popular publications like Cumhuriyet, Milliyet and Habertürk are also based in Istanbul.[299] Istanbul also has long-running Armenian language newspapers, notably the dailies Marmara and Jamanak and the bilingual weekly Agos in Armenian and Turkish.[301]

Radio broadcasts in Istanbul date back to 1927, when Turkey's first radio transmission came from atop the Central Post Office in Eminönü. Control of this transmission, and other radio stations established in the following decades, ultimately came under the state-run Turkish Radio and Television Corporation (TRT), which held a monopoly on radio and television broadcasts between its founding in 1964 and 1990.[302] Today, TRT runs four national radio stations; these stations have transmitters across the country so each can reach over 90 percent of the country's population, but only Radio 2 is based in Istanbul. Offering a range of content from educational programming to coverage of sporting events, Radio 2 is the most popular radio station in Turkey.[302] Istanbul's airwaves are the busiest in Turkey, primarily featuring either Turkish-language or English-language content. One of the exceptions, offering both, is Açık Radyo (94.9 FM). Among Turkey's first private stations, and the first featuring foreign popular music, was Istanbul's Metro FM (97.2 FM). The state-run Radio 3, although based in Ankara, also features English-language popular music, and English-language news programming is provided on NTV Radyo (102.8 FM).[303]

TRT-Children is the only TRT television station based in Istanbul.

Sky Turk—both based in the city—are mainly just known for their news coverage in Turkish. The BBC has a regional office in Istanbul, assisting its Turkish-language news operations, and the American news channel CNN established the Turkish-language CNN Türk there in 1999.[306]

As of 2019, excluding universities more than 3.1 million students attended

Istanbul Lisesi and Cağaloğlu Anatolian High School are among other public high schools in the city. Istanbul also contains high schools established by the European and American expatriates and missionaries in the 19th century that currently offer secular, foreign-language education such as Robert College, Deutsche Schule Istanbul, Sankt Georgs-Kolleg, Lycée Saint-Joseph and Liceo Italiano di Istanbul.[310] Furthermore Turkish citizens of Jewish, Armenian, Greek and Assyrian descent are allowed to establish and attend their respective schools as granted in the Treaty of Lausanne, Phanar Greek Orthodox College being an example.[311] Most high schools are highly selective and demand high scores from the national standardized LGS exam [tr] for admission, with Galatasaray and Robert College only accepting the top 0.1% to 0.01% of the exam takers.[312]

Istanbul contains almost a third of all

vocational universities of higher education. There are also military academies, including the Turkish Air Force Academy and Turkish Naval Academy as well as four foundation-owned vocational universities of higher education which are not affiliated with any university.[313]

Some of the most renowned and highly ranked universities in Turkey are in Istanbul.

Özyeğin Üniversitesi near Altunizade. Istanbul's first private university, Koç University, was founded as late as 1992, because private universities were not allowed in Turkey before the 1982 amendment to the constitution.[309] Istanbul is also home to several conservatories and art schools, including Mimar Sinan Academy of Fine Arts, founded in 1882.[314]

Public universities with a major presence in the city, such as Istanbul University, Istanbul Technical University (the world's third-oldest university dedicated entirely to engineering, established in 1773), and Boğaziçi University (formerly the higher education section of Robert College until 1971) provide education in English as the primary foreign language, while the primary foreign language of education at Galatasaray University is French.[309]

Public services

The Ottoman Ministry of Post and Telegraph was established in 1840 and the first post office, the Imperial Post Office, opened near the courtyard of Yeni Mosque. By 1876, the first international mailing network between Istanbul and the lands beyond the Ottoman Empire had been established.[320] Sultan Abdülmecid I issued Samuel Morse his first official honor for the electrical telegraph in 1847, and construction of the first telegraph line—between Istanbul and Edirne—finished in time to announce the end of the Crimean War in 1856.[321]

Grand Post Office in Sirkeci, Istanbul, was designed by Vedat Tek in the Turkish neoclassical style of the early 20th century.[322]

A nascent telephone system began to emerge in Istanbul in 1881 and after the first manual telephone exchange became operational in Istanbul in 1909, the Ministry of Post and Telegraph became the Ministry of Post, Telegraph, and Telephone.[320][323] GSM cellular networks arrived in Turkey in 1994, with Istanbul among the first cities to receive the service.[324] Today, mobile and landline service is provided by private companies, after Türk Telekom, which split from the Ministry of Post, Telegraph, and Telephone in 1995, was privatized in 2005.[320][324] Postal services remain under the purview of what is now the Post and Telegraph Organization (retaining the acronym PTT).[320]

In 2000, Istanbul had 137 hospitals, of which 100 were private.

Environmentalist groups worry that the third bridge will endanger the remaining green areas to the north of Istanbul.[336][337] Apart from the three Bosphorus Bridges, the dual-deck, 14.6-kilometer (9.1 mi) Eurasia Tunnel (which entered service on 20 December 2016) under the Bosphorus strait also provides road crossings for motor vehicles between the Asian and European sides of Turkey.[338] Road transport emits significant carbon dioxide, estimated at 7 million tons in 2021.[339]

This rail line has 76.6 km (47.6 mi), and the full line opened on 12 March 2019.[348] Until then, buses provide transportation within and between the two-halves of the city, accommodating 2.2 million passenger trips each day.[349] The Metrobus, a form of bus rapid transit, crosses the Bosphorus Bridge, with dedicated lanes leading to its termini.[350]


There are three main

Şehir Hatları operates the traditional vapur ferries on 891 daily trips between 53 piers across the Bosporus and the Princes' Islands[351]

The privately owned İDO (Istanbul Sea Buses) runs a combination of high-speed passenger ferries and vehicle ferries within Istanbul and to destinations across the Sea of Marmara.[352] A smaller private company, Turyol also operates services across the Bosphorus. The city's main cruise ship terminal is the Port of Istanbul in Karaköy, with a capacity of 10,000 passengers per hour.[353]


Sirkeci Terminal building was constructed between 1888 and 1890, and became the eastern terminus of the Orient Express from Paris.[354]

International rail service from Istanbul launched in 1889, with a line between Bucharest and Istanbul's

Ankara-Istanbul high-speed railway forced the station to close in 2012.[360] New stations to replace both the Haydarpaşa and Sirkeci terminals, and connect the city's disjointed railway networks, now the Marmaray second phase opened to the public.[360] Private bus companies still operation to this day. Istanbul's main bus station is the largest in Europe, with a daily capacity of 15,000 buses and 600,000 passengers, serving destinations as distant as Frankfurt.[361][362]


Istanbul has had three large international airports, two of which currently serve commercial passenger flights. The largest is the new Istanbul Airport, opened in 2018 in the Arnavutköy district to the northwest of the city center, on the European side, near the Black Sea coast.

Sabiha Gökçen Airport

All scheduled commercial passenger flights were transferred from

IATA code IST was also transferred to the new airport.[364] Once all phases are completed in 2025, the airport will have six sets of runways (eight in total), 16 taxiways, and will be able to accommodate 200 million passengers a year.[365][366]
The transfer from the airport to the city is via the O-7, and it will eventually be linked by two lines of the Istanbul Metro.

Sabiha Gökçen International Airport, 45 kilometers (28 mi) southeast of the city center, on the Asian side, was opened in 2001 to relieve Atatürk. Dominated by low-cost carriers, Istanbul's second airport has rapidly become popular, especially since the opening of a new international terminal in 2009;[367] the airport handled 14.7 million passengers in 2012, a year after Airports Council International named it the world's fastest-growing airport.[368][369] Atatürk had also experienced rapid growth, as its 20.6 percent rise in passenger traffic between 2011 and 2012 was the highest among the world's top 30 airports.[370]

Istanbul Atatürk Airport, located 24 kilometers (15 mi) west of the city center, on the European side, near the Marmara Sea coast, was formerly the city's largest airport. After its closure to commercial flights in 2019, it was briefly used by cargo aircraft and the official state aircraft owned by the Turkish government, until the demolition of its runway began in 2020. It handled 61.3 million passengers in 2015, which made it the

18th-busiest in the world in that year.[370]

  5. ^ The foundation of Byzantion (Byzantium) is sometimes, especially in encyclopedic or other tertiary sources, placed firmly in 667 BCE. Historians have disputed the precise year the city was founded. Commonly cited is the work of 5th-century-BCE historian Herodotus, which says the city was founded seventeen years after Chalcedon,[34] which came into existence around 685 BCE. Eusebius concurs with 685 BCE as the year Chalcedon was founded, but places Byzantion's establishment in 659 BCE.[35] Among more modern historians, Carl Roebuck proposed the 640s BCE[36] and others have suggested even later. The foundation date of Chalcedon is itself subject to some debate; while many sources place it in 685 BC,[37] others put it in 675 BCE[38] or even 639 BCE (with Byzantion's establishment placed in 619 BCE).[35] Some sources refer to Byzantium's foundation as the 7th century BCE.
  6. ^ a b Historians disagree—sometimes substantially—on population figures of Istanbul (Constantinople), and other world cities, prior to the 20th century. A follow-up to Chandler & Fox 1974,Chandler 1987, pp. 463–505[72] examines different sources' estimates and chooses the most likely based on historical conditions; it is the source of most population figures between 100 and 1914. The ranges of values between 500 and 1000 are due to Morris 2010, which also does a comprehensive analysis of sources, including Chandler (1987); Morris notes that many of Chandler's estimates during that time seem too large for the city's size, and presents smaller estimates. Chandler disagrees with Turan 2010 on the population of the city in the mid-1920s (with the former suggesting 817,000 in 1925), but Turan, p. 224, is used as the source of population figures between 1924 and 2005. Turan's figures, as well as the 2010 figure,[178] come from the Turkish Statistical Institute. The drastic increase in population between 1980 and 1985 is largely due to an enlargement of the city's limits (see the Administration section). Explanations for population changes in pre-Republic times can be inferred from the History section.
