Consequences of the Black Death
The Black Death peaked in Europe between 1348 and 1350, with an estimated third of the continent's population ultimately succumbing to the disease. Often simply referred to as "The Plague", the Black Death had both immediate and long-term effects on human population across the world as one of the most devastating pandemics in human history, including a series of biological, social, economic, political and religious upheavals that had profound effects on the course of world history, especially European history.
