What is roman empire flag?

The Roman Empire did not have a specific flag that represented the entirety of the empire. Instead, the Romans displayed military standards (signum) in battle, which were tall poles with various symbols or emblems representing different legions or military units. These standards were usually topped with a metal eagle or other animal figurine.

The most well-known symbol of the Roman Empire was the SPQR acronym, which stands for Senatus Populusque Romanus (The Senate and People of Rome). This was a common emblem used on various objects and structures throughout the empire to symbolize Roman authority and unity.

During the reign of the Roman Empire, there were also various imperial banners and emblems used by individual emperors to symbolize their power and authority. These often featured symbols such as eagles, laurel wreaths, and other imagery associated with the Roman state.

Overall, the Roman Empire did not have a standardized flag as we think of it today, but instead used a variety of symbols and emblems to represent its power and authority.
