Learning goals
Learners will
- Describe how the Black Death spread.
- Explain medieval and modern understandings of its cause.
- Analyse its short-term and long-term effects.
Success looks like
- I can trace the spread of the plague on a map.
- I can compare medieval explanations with modern scientific understanding.
- I can explain at least two long-term consequences.
The big idea
The Black Death was a devastating pandemic of plague in the mid-1300s. It is believed to have begun in Central Asia and spread along trade routes. It reached the Black Sea region and then Sicily by ship in 1347, and swept across Europe between 1347 and 1351.
Modern science has shown that the plague was caused by the bacterium *Yersinia pestis*. It could spread through bites from fleas carried by rats, and through other routes such as person to person, especially in the pneumonic form affecting the lungs.
People at the time did not know about bacteria. Many believed the plague was a punishment from God, or was caused by 'bad air' (miasma) or the position of the planets. Some groups, such as Jewish communities, were cruelly made scapegoats and attacked.
The death toll was enormous. Historians estimate that roughly a third to a half or more of Europe's population died, though exact numbers are uncertain because records are incomplete.
Short-term consequences included abandoned villages, fields left unharvested and widespread fear. Some cities, such as Venice and Ragusa (Dubrovnik), introduced quarantine measures.
Long-term consequences included labour shortages. Surviving peasants could demand higher wages and better conditions, weakening serfdom in parts of Western Europe. Rulers tried to freeze wages, contributing to unrest such as the English Peasants' Revolt of 1381.
Worked examples
Cause and consequence chain
Explain how the Black Death could lead to higher wages.
- The plague killed a large proportion of workers.
- Fewer workers meant lords struggled to find labour.
- Surviving workers could demand higher pay or move to better offers.
Answer: Fewer workers increased the value of labour, pushing wages up.
Estimating a death toll
A town of 6,000 lost one third of its population. How many died?
- One third of 6,000 = 6,000 ÷ 3 = 2,000.
Answer: 2,000 people.

Answer guide for parents
What caused the Black Death, according to modern science?
The bacterium Yersinia pestis — The bacterium Yersinia pestis caused plague.
How did plague mainly reach Europe?
Along trade routes and by ship — Trade routes and ships spread the disease.
Which was a long-term consequence of the Black Death in Western Europe?
Labour shortages helped raise wages — Fewer workers meant labour was more valuable.
What is a scapegoat?
A person or group unfairly blamed — Some communities were wrongly blamed and attacked.
Why are death toll figures for the Black Death given as estimates?
Records from the time are incomplete — Medieval records were incomplete and inconsistent.
In what year did the plague reach Sicily?
1347 — Plague arrived in Sicily by ship in 1347.
Isolating people to stop disease spreading is called ____.
quarantine — Quarantine was used by some medieval cities.
A village of 900 people lost half its population. How many people died?
450 — 900 ÷ 2 = 450.
Watch out for
- Many believe rats alone spread the plague. Fleas and person-to-person transmission also played roles, and historians and scientists continue to debate the balance.
- Some think the Black Death only affected Europe. It also devastated parts of Asia, the Middle East and North Africa.
Tips for parents
- If your child is anxious about disease, emphasise how modern medicine, antibiotics and public health now protect us.
- Compare responses to the Black Death with responses to recent pandemics, focusing on how understanding of disease has changed.
- Discuss scapegoating sensitively and link it to fairness today.
Go further
- Draw a map showing the spread of plague from 1347 to 1351.
- Investigate a primary source account of the plague (for example Boccaccio's description of Florence) in a library collection.
- Create a cause-and-effect flowchart linking the Black Death to the Peasants' Revolt.
