Consequences

Figures for the death toll vary widely by area and from source to source as new research and discoveries come to light. It killed an estimated 75 million to 200 million people in the 14th century. According to medieval historian Philip Daileader in 2007:

The trend of recent research is pointing to a figure more like 45 percent to 50 percent of the European population dying during a four-year period. There is a fair amount of geographic variation. In Mediterranean Europe, areas such as Italy, the south of France and Spain, where plague ran for about four years consecutively, it was probably closer to 75 percent to 80 percent of the population. In Germany and England ... it was probably closer to 20 percent.

The most widely accepted estimate for the Middle East, including Iraq, Iran and Syria, during this time, is for a death rate of about a third. The Black Death killed about 40% of Egypt's population. Half of Paris's population of 100,000 people died. In Italy, Florence's population was reduced from 110,000 or 120,000 inhabitants in 1338 to 50,000 in 1351. At least 60 percent of Hamburg's and Bremen's population perished. Before 1350, there were about 170,000 settlements in Germany, and this was reduced by nearly 40,000 by 1450. In 1348, the plague spread so rapidly that before any physicians or government authorities had time to reflect upon its origins, about a third of the European population had already perished. In crowded cities, it was not uncommon for as much as 50 percent of the population to die. Europeans living in isolated areas suffered less, whereas monks and priests were especially hard hit since they cared for the Black Death's victims.
