Istanbul Province (İstanbul)
Istanbul (, ; İstanbul ), formerly known as Constantinople (Κωνσταντινούπολις; Constantinopolis), is the largest city in Turkey, serving as the country's economic, cultural and historic hub. The city straddles the Bosporus strait, lying in both Europe and Asia, and has a population of over 15 million residents, comprising 19% of the population of Turkey. Istanbul is the most populous European city, and the world's 15th-largest city.

The city was founded as Byzantium (Βυζάντιον, Byzantion) in the 7th century BCE by Greek settlers from Megara. In 330 CE, the Roman emperor Constantine the Great made it his imperial capital, renaming it first as New Rome (Νέα Ῥώμη, Nea Rhomē; Nova Roma) and then as Constantinople (Constantinopolis) after himself. 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 served as an imperial capital for almost 1600 years: during the Roman/Byzantine (330–1204), Latin (1204–1261), late Byzantine (1261–1453), and Ottoman (1453–1922) empires. The city played a key role in the advancement of Christianity during Roman/Byzantine times, hosting four (including Chalcedon (Kadıköy) on the Asian side) of the first seven ecumenical councils (all of which were in present-day Turkey) 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.

In 1923, after the Turkish War of Independence, Ankara replaced the city as the capital of the newly formed Republic of Turkey. In 1930, the city's name was officially changed to Istanbul, the Turkish rendering of εἰς τὴν Πόλιν ( romanized: eis tḕn Pólin; 'to the City'), the appellation Greek speakers used since the 11th century to colloquially refer to the city.

Over 13.4 million foreign visitors came to Istanbul in 2018, eight years after it was named a European Capital of Culture, making it the world's eighth most visited city. Istanbul is home to several UNESCO World Heritage Sites, and hosts the headquarters of numerous Turkish companies, accounting for more than thirty percent of the country's economy.

The first known name of the city is Byzantium (Βυζάντιον, Byzántion), the name given to it at its foundation by Megarian colonists around 657 BCE. Megarian colonists claimed a direct line back to the founders of the city, Byzas, the son of the god Poseidon and the nymph Ceroëssa. Modern excavations have raised the possibility that the name Byzantium might reflect the sites of native Thracian settlements that preceded the fully-fledged town. Constantinople comes from the Latin name Constantinus, after Constantine the Great, the Roman emperor who refounded the city in 324 CE. Constantinople remained the most common name for the city in the West until the 1930s, when Turkish authorities began to press for the use of "Istanbul" in foreign languages. Ḳosṭanṭīnīye (قسطنطينيه) and İstanbul were the names used alternatively by the Ottomans during their rule.

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-). A person from the city is an İstanbullu (plural: İstanbullular); Istanbulite is used in English.

Turkey (Türkiye ), officially the Republic of Türkiye (Türkiye Cumhuriyeti ), is a transcontinental country located mainly on the Anatolian Peninsula in Western Asia, with a small portion on the Balkan Peninsula in Southeast Europe. It shares borders with the Black Sea to the north; Georgia to the northeast; Armenia, Azerbaijan, and Iran to the east; Iraq to the southeast; Syria and the Mediterranean Sea to the south; the Aegean Sea to the west; and Greece and Bulgaria to the northwest. Cyprus is located off the south coast. Turks form the vast majority of the nation's population and Kurds are the largest minority. Ankara is Turkey's capital, while Istanbul is its largest city and financial centre.

One of the world's earliest permanently settled regions, present-day Turkey was home to important Neolithic sites like Göbekli Tepe, and was inhabited by ancient civilisations including the Hattians, Hittites, Anatolian peoples, Mycenaean Greeks, Persians and others. Following the conquests of Alexander the Great which started the Hellenistic period, most of the ancient regions in modern Turkey were culturally Hellenised, which continued during the Byzantine era. The Seljuk Turks began migrating in the 11th century, and the Sultanate of Rum ruled Anatolia until the Mongol invasion in 1243, when it disintegrated into small Turkish principalities. Beginning in the late 13th century, the Ottomans united the principalities and conquered the Balkans, and the Turkification of Anatolia increased during the Ottoman period. After Mehmed II conquered Constantinople (Istanbul) in 1453, Ottoman expansion continued under Selim I. During the reign of Suleiman the Magnificent, the Ottoman Empire became a global power. From the late 18th century onwards, the empire's power declined with a gradual loss of territories. Mahmud II started a period of modernisation in the early 19th century. The Young Turk Revolution of 1908 restricted the authority of the Sultan and restored the Ottoman Parliament after a 30-year suspension, ushering the empire into a multi-party period. The 1913 coup d'état put the country under the control of the Three Pashas, who facilitated the Empire's entry into World War I as part of the Central Powers in 1914. During the war, the Ottoman government committed genocides against its Armenian, Greek and Assyrian subjects. After its defeat in the war, the Ottoman Empire was partitioned.
