The Catastrophic Year: Why 536 AD Was the Worst in Human History
When considering the darkest periods in human history, events like the Black Death or the 1918 flu pandemic often come to mind. However, historian Michael McCormick identifies 536 AD as possibly the worst year ever. A mysterious, persistent fog enveloped Europe, the Middle East, and parts of Asia, leading to widespread devastation.
For nearly 18 months, a dense haze obscured the sun, casting regions into darkness. Byzantine historian Procopius noted, “For the sun gave forth its light without brightness, like the moon, during the whole year.” This phenomenon caused temperatures in the Northern Hemisphere to drop by 1.5°C to 2.5°C, making the 530s one of the coldest decades on record. China experienced summer snowfall, crops failed globally, and famine ensued. Irish chronicles report severe food shortages from 536 to 539.
