How many years has the world been at war?

Answer 1

Determining exactly how many years the world has been at war is complex, as conflicts have varied in scale and duration throughout history. Major global conflicts, such as the World Wars, and numerous regional wars and civil conflicts have occurred over centuries. While there have been periods of relative peace, many regions have experienced warfare simultaneously, suggesting that war has been a persistent aspect of human history for thousands of years. In total, it is estimated that humanity has spent a significant portion of its history—potentially hundreds of years—engaged in various forms of conflict.
