The Black Death did not hit everyone the same way, and the fatality rates read like a grim checklist of how fast things could turn: septicemic plague could kill within 24 hours without antibiotics, while untreated bubonic plague often peaked in deaths around days 3 to 5. One winter wave pushed pneumonic plague toward near 90 to 100% fatality because it spread through respiratory droplets, not just flea bites. By setting these outcomes beside details like incubation of 2 to 6 days and hallmark signs such as blackened gangrene and cough with bloody sputum, the statistics quickly stop feeling abstract and start looking disturbingly specific.
Key Takeaways
- The bubonic plague form had a 30-60% fatality rate untreated
- Pneumonic plague fatality approached 90-100% if untreated, spreading via respiratory droplets
- Septicemic plague killed within 24 hours with 100% fatality without antibiotics
- Art production shifted to smaller scales, with panel paintings up 40%
- Boccaccio's Decameron (1353) immortalized plague's social breakdown
- Dance of Death motif appeared in 70+ artworks post-1348
- Europe's population declined by 30-60% between 1347-1351 due to the pandemic
- In Florence, Italy, 60% of the population died within four months in 1348
- England lost 40-50% of its population, from 6 million to 3 million
- The Black Death first arrived in Europe via Messina, Sicily, on October 15, 1347, carried by Genoese ships from the Crimea
- It spread from the Crimea to Constantinople by 1347, killing Emperor John VI Kantakouzenos's son
- By January 1348, the plague reached Marseille, France, from Italian ships
- Wages for agricultural laborers in England rose 40% by 1350 due to labor shortage
- Real wages in Europe doubled between 1340 and 1400 post-plague
- Land rents in England fell 30-50% as landowners struggled to find tenants
