Constantinople (see other names) was a historical city located on the Bosporus that served as the capital of the Roman, Byzantine, Latin, and Ottoman empires between its consecration in 330 until 1930, when it was renamed to Istanbul. Initially as New Rome, Constantinople was founded in 324 during the reign of Constantine the Great on the site of the existing settlement of Byzantium, and shortly thereafter in 330 became the capital of the Roman Empire.
