What is the relationship between the ancient Roman Empire and the Babylonian Empire and Constantinople?

In 330 AD, the Roman emperor Constantine felt that the empire was tottering and needed new strength and spirit to make Asia and Europe prosperous. So he built a "new capital" on the site of the old Byzantine city and named it "Constantinople" after himself. In other words, it was once the capital of the Roman Empire. Later, ancient Rome was divided into East Rome and West Rome, which was the capital of East Rome (Byzantine Empire).

As for Babylon, I'm sorry, ancient Babylon and new Babylon have nothing to do with Constantinople. There was a battle of Babylon between the Byzantine Empire and the Muslim army. Is that what the landlord asked?
