A major volcanic eruption that occurred in the year 536 caused 18 months of total darkness, drastically altering the global climate and causing profound social consequences. Sunlight became extremely weak in Europe, the Middle East, and Asia for months, summer lost much of its heat, and crops failed, resulting in famine and social destabilization. Although the exact location of the volcano has not yet been fully determined, the climatic evidence confirms that this event was not merely an apocalyptic account, but rather a volcanic disturbance of global scale with lasting impacts on the history of humanity.
