Constantinople (Greek: Κωνσταντινούπολις, romanizedKōnstantinoúpolis; Latin: Constantinopolis) was the capital city of the Roman Empire from 330 AD and later what historians called the Byzantine Empire. Constantinople was located in the Bosporus, the strait between the Balkans and Asia Minor.

For centuries the city was not very large, and was called Byzantium. In the 4th century, Roman emperor Constantine the Great made Byzantium the capital of the Roman Empire and renamed it to Constantinople.

In the 13th century, Constantinople was looted and captured by crusaders during the Fourth Crusade. The crusaders created the Latin Empire (1204–1261), with Constantinople as the capital city. In 1261, the Empire of Nicaea successfully restored the Byzantine Empire, under the rule of the Palaiologos dynasty.

In 1453 the Ottoman sultan Mehmed the Conqueror captured Constantinople. The city was renamed Istanbul and became the capital of the Ottoman Empire (1453–1922).

Over time, the city's short name in Greek: Πόλις Pólis 'city' became the name Istanbul. This name became the city's official name in 1930, during the government of Mustafa Kemal Atatürk.
