The Black Death, also known as the Pestilence, the Great Plague or the Plague, or less commonly the Black Plague, was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to 200 million people in Eurasia, peaking in Europe from 1347 to 1351. The bacterium Yersinia pestis, which results in several forms of plague is believed to have been the cause. The Black Death was the first major European outbreak of plague and the second plague pandemic. The plague created a number of religious, social and economic upheavals, with profound effects on the course of European history. Wikipedia Reference »
