What students do
- Trace the plague's route out of Central Asia along the Silk Road to Caffa and into Messina, Sicily, in 1347
- Explain how Yersinia pestis spread through fleas on rats and, in its pneumonic form, from person to person
- Read Boccaccio's eyewitness account of Florence in 1348 and describe what he saw
- Explain how the death toll and the labor shortage that followed helped weaken serfdom in Western Europe
What it covers
- The plague's route from Central Asia along the Silk Road to Messina, Sicily, in October 1347
- What Yersinia pestis did to the body, including buboes and the person to person pneumonic form
- Medieval responses to the plague, including quarantine, flight, flagellants, and the scapegoating of Jewish communities
- Boccaccio's 1348 eyewitness account and how the plague's aftermath weakened serfdom in Western Europe
Learning targets
- Trace how the Black Death traveled out of Central Asia along the Silk Road to the Black Sea port of Caffa, reached Messina, Sicily, in October 1347, and covered most of Europe within about four years.
- Explain how the plague spread and what it did to the body: Yersinia pestis carried by fleas on rats, buboes as the first visible sign, and the pneumonic form spreading person to person by coughing.
- Describe the death toll - roughly one-third to one-half of Europe - and explain why medieval medicine could not stop it, and how people responded through quarantine, flight, the flagellants, and the scapegoating and murder of Jewish communities.
- Analyze a primary source - Boccaccio's eyewitness account of Florence in 1348 - and explain how the labor shortage that followed the plague pushed wages up and helped weaken serfdom in Western Europe.
Peek inside
A Pandemic and Its Cause
BLACK DEATH was the pandemic of that swept Europe from 1347 to 1351 and killed roughly one-third to one-half of the population.
YERSINIA PESTIS is the that causes plague; it lives in fleas that feed on rats and other rodents.
1. What is the name of the plague pandemic that swept Europe from 1347 to 1351 and killed roughly one-third to one-half of the population?
Why this matters
The year 1347 is where this reading starts counting, tracking the plague's route out of Central Asia, through Caffa, into Messina, Sicily that October, then across most of Europe within about four years. A death toll of roughly a third to half of the continent only becomes real once students trace the actual path themselves.
I keep the sequence in strict order because a heavy topic like this needs structure more than sympathy. The labor shortage that followed is the part students remember least and argue with most, since a plague weakening serfdom sounds backwards until they see how few workers were left for landlords to bargain with.
From one teacher to another
This is a heavy topic, so I built it to move through the facts in order rather than linger on any one image. Students trace the plague's route out of Central Asia along the Silk Road to the port of Caffa, then to Messina, Sicily, in October 1347, and across most of Europe within about four years. They learn what Yersinia pestis actually did: how fleas on rats spread it, what the buboes looked like, and how the pneumonic form spread directly from person to person by coughing. From there, students read Boccaccio's eyewitness account of Florence in 1348 and use it alongside the death toll, roughly a third to a half of Europe, to understand how medieval society responded: quarantine, flight, flagellants, and the scapegoating and murder of Jewish communities. The lesson closes on the labor shortage that followed and how it helped weaken serfdom in Western Europe. Guided notes track the slides, and the activity, quiz, and exit ticket all come with answer keys.
