The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1348 and 1350, and killing between 75 million and 200 million people. Although there were several competing theories as to the etiology of the Black Death, recent analysis of DNA from victims in northern and southern Europe indicates that the pathogen responsible was the Yersinia pestis bacterium probably causing several forms of plague.
