The Black Death was an epidemic outbreak of bubonic plague in Europe around 1348 that killed between one-third and two-thirds of the population in less than five years. The epidemic spanned from China to England to North Africa, transmitted along the Silk Road and other trade routes. Worldwide, the plague may have killed one-quarter of all people. Repeated outbreaks continued in Europe into the 18th century. Some historians believe the drastic reduction in population hurried the end of feudalism by raising the value of labor and the power of workers, as seen in incidents like the 1381 Peasants Revolt in England.
The Black Plague, also known as the Black Death, resulted in the  deaths of between 75 to 200-million people in Europe in between  1346 and 1353. The Black Death is thought â¦ to have originated in the  plains of central Asia, then traveled along the Silk Road to  Crimea.
