Ottoman Empire. The city, known alternatively in Ottoman Turkish as Ḳosṭanṭīnīye (قسطنطينيه after the Arabic form al-Qusṭanṭīniyyah القسطنطينية) or Istanbul (while its Christian minorities continued to name it Constantinople), was the capital of the Ottoman Empire from its conquest in 1453 until the empire's collapse in 1922.
