How did the Black Death change the European economy?

The plague had an important effect on the relationship between the lords who owned much of the land in Europe and the peasants who worked for the lords. As people died, it became harder and harder to find people to plow fields, harvest crops, and produce other goods and services. Peasants began to demand higher wages.

A lot mostly from slaves.

Explanation:

The Black Death was a great tragedy. However, the decrease in population caused by the plague increased the wages of peasants.
