When was rome at its peek?

Rome reached its peak during the Pax Romana, a period of relative peace and stability that lasted from 27 BCE to around 180 CE. This era began with the reign of Emperor Augustus, who established a strong centralized government and expanded the empire's borders. The population of Rome grew, trade flourished, and the arts and architecture thrived, marking a high point in Roman civilization. The peak is often considered to culminate during the reign of Emperor Trajan (98-117 CE), when the empire reached its greatest territorial extent.
