Answer: The Byzantine Empire fell to the Ottoman Empire
I MAY BE WRONG
check the next person's answer, they're probably right.
Step-by-step explanation:
I used deductive reasoning, it makes sense to me this way.
Rome was already a place before Caesar was in charge, and i don't think he was ever officially an Emperor.
Why would the Colosseum be built before Ancient Rome was a place?
And why would Christianity be declared Rome's main religion if Rome wasn't a place yet? also im not sure if it ever was the main religion, or if it was it was NOT in early Rome.
So i'm assuming that the fall of the Byzantine empire is what brought about Rome. if not, then everything i said above doesn't matter.
hope this helps, I may be wrong.
