Constantinople (see other names) was the historical name for the city of Istanbul up until 1930, located on a peninsula at the southeastern tip of Thrace in Europe; with the Bosporus strait and the ancient cities of Chalcedon and Chrysopolis in Bithynia, Anatolia (Asia Minor) to the east; the Golden Horn and the citadel of Galata (Pera) to the north; the Sea of Marmara to the south; and the Princes' Islands to the southeast. Constantinople served as the capital of the Roman, Byzantine, Latin, and Ottoman Empires between its consecration in 330 and the formal abolition of the Ottoman sultanate in 1922. Constantinople was founded in 324, initially as New Rome, during the reign of Constantine the Great on the site of the existing settlement of Byzantium and in 330 became the new capital of the Roman Empire (330–395).
