🏛️Ancient Mediterranean Unit 15 – The Pax Romana and the High Empire

The Pax Romana, or "Roman Peace," marked a 200-year period of stability in the Roman Empire from 27 BCE to 180 CE. This era saw economic growth, cultural exchange, and advancements in art, literature, and engineering, allowing Rome to expand its territories and influence. Key figures like Augustus, Trajan, and Marcus Aurelius shaped the empire during this time. The Principate system of government concentrated power in the emperor's hands while maintaining a republican facade. Trade flourished, cities grew, and Roman culture spread throughout the provinces.
