The Black Death is a deadly plague that swept through Europe between 1347 and 1351. It arrived in Europe from Asia through trade. It killed over 20 million people, one third of Europes population was dead. Doctors used simple techniques such as bloodletting boil-balancing and superstitious practices such as burning herbs and bathing in rose water and vinegar. Some people thought that the Black Death was a kind of punishment from god. The plague faded out after three years but reappeared every few generations for centuries. So many people died there was a serious labor shortage all over Europe which to workers demanded higher wages which land lords refused to pay them. Peasants left the manors and went to cities to find employment. The disease also hurt the church because people didn't understand why their prays weren't being answered. Modern sanitation and public health practices have changed how the disease spread but have not eliminated it.
