For centuries, the aurora borealis inspired both wonder and fear. In medieval Europe, red or unusually bright auroras were often seen as omens of war, plague, or political collapse. Chroniclers described nights when the sky “blazed like fire,” interpreting the phenomenon as a warning of impending disasters. Some even believed that the lights foretold the fate of entire nations and the downfall of kingdoms, lending the aurora a reputation as a celestial messenger of doom.
