Near the end of the Western Roman Empire, it becomes Ravenna. And of course we talk about Constantine changing the capital to Byzantium, which eventually became Constantinople. And that's the official start of at least the roots of the Byzantine Empire, although Constantine was emperor of both. It's fair to say that Rome was the capital of the Roman Empire from its early days as a kingdom all the way until the first several centuries of the Common Era. The roots of the Byzantine Empire are with Constantine changing the capital, the seat of power of the combined empire, and moving it from Rome to Byzantium, which will eventually be called Constantinople. Now let's think about language. So the language of the Roman Empire is Latin.
