In the 14th century, the plague spreaded rapidly over Europe and destroyed a huge amount of the population. The Black Death was a disease that spreads really quickly and affects many people/individuals all at one time. The symptoms include fever, chills, vomiting, diarrhea aches and pains, and death.
The effects of the plague included modern sanitation and public-health. So many people died that their was a serious labor shortage all over Europe. This meant that they got higher wages because or els they would quit, this would be alright but becausw there was so many people waiting for a job because that was the only way to live, most of the people without jobs died. So the population went down, so then there were less people waiting for a job, the landlord needsed the worker just as much as they need him, so they raised the wages.
The only thing that doctors did was bloodleading and rose water and vinegar. Some people thought that the Black Death was a kind of punishment from God so they would punish themselves by hurting themselves to say that they were sorry.
