Istanbul is the largest city in Turkey, a megacity, constituting the country's economic, cultural, and historical center. With a population of over 15 million, it is home to 18% of the population of Turkey. Istanbul is among the largest cities in Europe and in the world by population.
It is a city on two continents; about two-thirds of its population live in Europe and the rest in Asia. Istanbul straddles the Bosphorus – one of the world's busiest waterways – in northwestern Turkey, between the Sea of Marmara and the Black Sea. Its area of 5,461 square kilometers (2,109 mi2) is coterminous with Istanbul Province.
The city developed to become one of the most significant cities in history. Byzantium was founded on the (present-day) Sarayburnu promontory by Greek colonists in the seventh century BC.
Over nearly 16 centuries following its reestablishment as Constantinople in 330 AD, it served as the capital of four empires: the Roman Empire (330–395), the Eastern Roman (Byzantine) Empire (395–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922).
