when did the roman capital move to constantinople
Constantinople Constantinople (Greek: Κωνσταντινούπολις Konstantinoúpolis; Latin: Constantinopolis) 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 AD 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 AD.[5]
Constantinople Constantinople was the largest and richest urban center in the Eastern Mediterranean Sea during the late Eastern Roman Empire, mostly as a result of its strategic position commanding the trade routes between the Aegean Sea and the Black Sea. It would remain the capital of the eastern, Greek-speaking empire for over a thousand years. At its peak, roughly corresponding to the Middle Ages, it was the richest and largest European city, exerting a powerful cultural pull and dominating economic life in the Mediterranean. Visitors and merchants were especially struck by the beautiful monasteries and churches of the city, in particular, Hagia Sophia, or the Church of Holy Wisdom: A Russian 14th-century traveler, Stephen of Novgorod, wrote, "As for Hagia Sophia, the human mind can neither tell it nor make description of it."
Constantinople Byzantium took on the name of Konstantinoupolis ("city of Constantine", Constantinople) after its re-foundation under Roman emperor Constantine I, who transferred the capital of the Roman Empire from Rome to Byzantium in 330 AD and designated his new capital officially as Nova Roma (Νέα Ῥώμη) 'New Rome'. During this time, the city was also called 'Second Rome', 'Eastern Rome', and Roma Constantinopolitana.[20] As the city became the sole remaining capital of the Roman Empire after the fall of the West, and its wealth, population, and influence grew, the city also came to have a multitude of nicknames.[citation needed]
New Delhi Calcutta (now Kolkata) was the capital of India during the British Raj until December 1911.
