Consequences

Economic

With such a large population decline from the pandemic, wages soared in response to a labour shortage. On the other hand, in the quarter century after the Black Death in England, it is clear many labourers, artisans, and craftsmen, those living from money-wages alone, did suffer a reduction in real incomes owing to rampant inflation. Landowners were also pushed to substitute monetary rents for labour services in an effort to keep tenants.

Environmental

Some historians believe the innumerable deaths brought on by the pandemic cooled the climate by freeing up land and triggering reforestation. This may have led to the Little Ice Age.

Persecutions

Renewed religious fervour and fanaticism bloomed in the wake of the Black Death. Some Europeans targeted "various groups such as Jews, friars, foreigners, beggars, pilgrims", lepers, and Romani, blaming them for the crisis. Lepers, and others with skin diseases such as acne or psoriasis, were killed throughout Europe.

Because 14th-century healers and governments were at a loss to explain or stop the disease, Europeans turned to astrological forces, earthquakes, and the poisoning of wells by Jews as possible reasons for outbreaks. Many believed the epidemic was a punishment by God for their sins, and could be relieved by winning God's forgiveness.

There were many attacks against Jewish communities. In the Strasbourg massacre of February 1349, about 2,000 Jews were murdered. In August 1349, the Jewish communities in Mainz and Cologne were annihilated. By 1351, 60 major and 150 smaller Jewish communities had been destroyed. During this period many Jews relocated to Poland, where they received a warm welcome from King Casimir the Great.
