How many years of peace since 1 AD?

Determining the exact number of years of peace since 1 AD is challenging due to the complexity of historical conflicts and varying definitions of peace. However, scholars estimate that out of the last 2,000 years, only about 250 years could be considered relatively peaceful, with significant periods of conflict occurring across different regions of the world. The Pax Romana (27 BC - 180 AD) is one notable example, but many other conflicts arose afterward, influencing global peace. Overall, the concept of "peace" can vary greatly depending on the context and region considered.
