The collapse of the Roman Empire
Did you know that the Roman Empire was once a large and mighty empire? They conquered most of Europe, Africa, and Asia during their height. However, after many years, they were eventually taken down when a group of barbarians sacked Rome.
I bet the ancient Romans would be shocked to know that their culture and history are still relevant today. They probably would have never guessed that we still use a lot of Roman numerals in modern times. I bet they would also be surprised to know that some people don’t understand that roman numerals are letters. So much for the empire!
