Bubonic plague - Wikipedia, the free encyclopedia

Bubonic plague—along with the septicemic plague and the pneumonic plague, which are the two other manifestations of Y. pestis—is generally believed to be the cause of the Black Death that swept through Europe in the 14th century and killed an estimated 75 million people, or 30-60% of the European population.[2] Because the plague killed so many of the working population, wages rose and some historians have seen this as a turning point in European economic development.
