Black Death Mortality in Europe: Historical Estimates

The Black Death (1347–1351), caused by Yersinia pestis, killed an estimated 75–200 million people across Eurasia and North Africa. In Europe alone, mortality was 30–60% of the population (~25–50 million dead).

Key Statistics

• Global Death Toll: 75–200 million (range reflects sparse records).
• European Population Loss: 30–60% (from ~80M to 30–50M).
• Peak Years: 1347–1351; recurrent waves until 18th century.
• Transmission: Flea vectors (Xenopsylla cheopis) on black rats; pneumonic spread in crowded conditions.

Societal Impact

• Labor shortage → end of serfdom, wage increases, peasant mobility.
• Religious upheaval: flagellants, persecution of Jews/lepers, questioning of Church.
• Economic restructuring: land consolidation, technological innovation.
• Art/literature: Danse Macabre, memento mori, Boccaccio's Decameron.

Modern Context

Plague still exists (endemic in rodents SW US, Africa, Asia). Treatable with antibiotics (streptomycin, doxycycline) if caught early. WHO reports 1,000–2,000 cases/year globally.
