Topic: Tell me a short, interesting fact about

One interesting fact about the Roman Empire is that the Roman Senate, the central political institution during the Republic era, continued to exist even after Emperor Augustus officially established the Roman Principate (27 BC) as a form of government. However, the Senate's power was significantly diminished, as it was the emperor who held the real authority. The Senate's primary roles in the Principate period included offering advice to the emperor, ratifying laws, and serving as a judicial body for some cases.
