Step-by-step explanation:
In the 1350s, the human population experienced a significant downturn due to the Black Death or the bubonic plague. The Black Death was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75-200 million people in Europe alone. It is estimated that the disease killed between 30-60% of Europe's population during that time. The cause of the Black Death is believed to have been the bacterium Yersinia pestis, which was transmitted through the bite of infected fleas carried by rats.
