What is the name of Constantinople now?

Constantinople is the old name of Istanbul, Turkey's largest city, and the ancient capital of Europe.

Now it refers to the area between Istanbul Golden Horn Bay and Malahi. It was once the capital of Roman Empire, Byzantine Empire, Latin Empire and Ottoman Empire. Western scholars used to call the city under Christian rule (from 330 to 1453) Constantinople, and the city under Islamic rule was called Istanbul. Constantine is an ancient Greek immigrant city, known as Byzantium, which was built by the Greeks in 660 BC. But the Roman Empire before Constantine did not get the attention it deserved. Constantine the Great of the Roman Empire rebuilt and expanded the Byzantine Empire.

In 330 AD, he announced that he would move the capital Byzantium to Constantinople, which means "the city of Constantine" and was nicknamed "New Rome". Since then, the city has begun its glorious thousand-year history. The name of Constantine was not merged with the city until 1453. In 395 AD, the Eastern Roman Empire and the Western Roman Empire formally split. As the capital of the Eastern Roman Empire (Byzantine Empire), Constantinople became the political, economic and cultural center of the Eastern Mediterranean.
