Topic: Tell me a short, interesting fact about

One fascinating fact about the Roman Empire is that it was not ruled by a single monarch but, rather, by a series of emperors who held the title of Augustus,± the first being Octavian, a name he took in 43 BC following the death of Julius Caesar. The Roman Empire was a form of government known as a primus inter pares, or "first among equals," which meant that the emperor was the top official in the Roman Senate and held ultimate authority, but still needed to work with and through the Senate, army, and popular assemblies to maintain power.
