Administration

Since 2004, the municipal boundaries of Istanbul have been coincident with the boundaries of its province. The city, considered capital of the larger Istanbul Province, is administered by the Istanbul Metropolitan Municipality (MMI), 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 Islamic judges and imams led the city under the auspices of the

, but they were not fully implemented until 1908 when the city was declared a province with nine constituent districts. This system continued beyond the founding of the Turkish Republic, with the province renamed a ''belediye'' (municipality), but the municipality was disbanded in 1957. 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. The main decision-making body of the Istanbul Metropolitan Municipality is the Municipal Council, with members drawn from district councils. The Municipal Council is responsible for citywide issues, including managing the budget, maintaining civic infrastructure, and overseeing museums and major cultural centers. 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. The Municipal Council is advised by the Metropolitan Executive Committee, although the committee also has limited power to make decisions of its own. 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. 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. All members of the district councils and the Municipal Council, including the metropolitan mayor, are elected to five-year terms. Representing the

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. Constantinople jostled with other major historical cities, such as

Politics

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'. 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. For Ekrem İmamoğlu, winning the mayorlty 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. 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 anti-AKP government protests began in İstanbul and spread throughout the nation. This trend first became evident electorally in the 2014 mayoral election where the center-left opposition candidate won an impressive 40% of the vote, despite not winning. The first government defeat in Istanbul occurred in the 2017 constitutional referendum, where Istanbul voted 'No' by 51.4% to 48.6%. The AKP government had supported a 'Yes' vote and won the vote nationally due to high support in rural parts of the country. The biggest defeat for the government came in the 2019 local elections, where their candidate for Mayor, former Prime Minister

Culture

Istanbul was historically known as a cultural hub, but its cultural scene stagnated after the Turkish Republic shifted its focus toward Ankara. 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. 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. 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. When additional universities and art journals were founded in Istanbul during the 1980s, artists formerly based in Ankara moved in. 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

Istanbul Atatürk Airport, located 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 passengers in 2015, which made it the third-busiest airport in Europe and the 18th-busiest in the world in that year.

Roe deer, wild boars, foxes, coyotes, martens, badgers, Wolf, wolves, weasels, wildcats, squirrels and Jungle cat, reed cats have been documented to live inside the boundaries of Istanbul Province.
