Blackdeath

The Black Death was a plague pandemic that occurred in Europe from 1346 to 1353. It was one of the most fatal pandemics in human history, leading to the death of up to 50 million people, around 30% to 60% of the European population and approximately 33% of the Middle Eastern population. The disease was caused by the bacterium Yersinia pestis, which is primarily spread by flea bites, though it may also spread through contact with infected tissues or fluids and, in pneumonic cases, through respiratory droplets.
