Topic: Tell me a short, interesting fact about

One interesting fact about the Roman Empire is that the Roman senate declared September 21 as the birthday of the city of Rome itself, a date known as the Anniversary of the City. This was a day filled with celebrations, parades, and games. It's interesting to note that this day is today's holiday known as "Festival of the Republic" or "Festa della Repubblica" in Italy, which commemorates the establishment of the Italian Republic in 1946.
