when did the roman capital moved to constantinople
Constantinople Constantinople (Greek: Κωνσταντινούπολις Kōnstantinoúpolis; Latin: Cōnstantīnopolis) was the capital city of the Roman/Byzantine Empire (330–1204 and 1261–1453), and also of the brief Latin (1204–1261), and the later Ottoman (1453–1923) empires. It was reinaugurated in 324 from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330.[5]
Constantinople From the mid-5th century to the early 13th century, Constantinople was the largest and wealthiest city in Europe[6] and it was instrumental in the advancement of Christianity during Roman and Byzantine times as the home of the Ecumenical Patriarch of Constantinople and as the guardian of Christendom's holiest relics such as the Crown of Thorns and the True Cross. After the final loss of its provinces in the early 15th century, the Byzantine Empire was reduced to just Constantinople and its environs, along with Morea in Greece, and the city eventually fell to the Ottomans after a month-long siege in 1453.
