So remember when I said the Roman Empire survived till the 15th century? Well, that was the Eastern Roman Empire, commonly known as the Byzantine Empire, although not by the people who lived in it, who identified themselves as Romans. So while the Western Roman Empire descended into chaos, the eastern half of the empire had its capital in Byzantium, a city on the Bosphorus Strait that Constantine would later rename Constantinople, thereby paving the way for what might be Giants' only mainstream hit. Constantine moved his headquarters, and thereby the headquarters of the Roman Empire, to Constantinople in 324 CE. Constantine had lots of reasons to move his capital east. For one thing, he was born in modern-day Croatia. Also, he probably spoke better Greek than Latin.
