The Black Plague, primarily the bubonic plague, was a devastating sickness caused by the microscopic bacterium Yersinia pestis. This disease killed an estimated 75 to 200 million people across Europe and Asia between 1347 and 1351. Learn how this tiny villain swept through medieval history!
Imagine a time when a scary sickness spread across the world so fast that people called it the Great Mortality. What could possibly cause something so devastating?
That terrifying event was the Black Death, which ravaged Europe between 1347 and 1351! It was one of the deadliest sicknesses in all of human history. People back then didn't have science or doctors like we do, so they were very confused and scared about where this terrible sickness came from. But *History's Not Boring* is here to explain the real, though still yucky, cause for all you awesome history explorers for kids!
Mira says:
"It’s wild to think that something as small as a flea, traveling on a rat, could change the course of history for millions of people! It really shows us how connected our world is, even back in the Middle Ages."
What is the Black Plague, Really?
The Black Plague wasn't just one sickness; it was a terrible group of diseases, but the main one we talk about is the bubonic plague! This sickness was caused by a tiny, tiny germ called the Yersinia pestis bacterium. You can't see it without a super powerful microscope, but this tiny germ was the real villain!
The plague came in a few scary forms, but the most common one was the bubonic plague, which caused painful, swollen lumps in places like the neck, armpits, and groin, called 'buboes.' Sometimes, the sickness made dark spots appear on the skin, which is partly why people later called it the 'Black Death'!
Mind-Blowing Fact!
The Black Death was so bad that some people living at the time called it the 'Great Pestilence' or 'The Great Mortality' because they thought the world was ending!
Shocking Numbers of the Great Mortality
The numbers from the Black Death are hard to even imagine! Think about your whole school, your neighborhood, and your town—and then multiply that by a huge amount. That's how many people were affected.
It is estimated that the Black Death killed between 75 million and 200 million people across Europe and Asia! In Europe alone, some historians think it wiped out about one-third of the entire population in just a few years.

How Did the Germ Travel So Far and So Fast?
So, if the germ was so small, how did it cross entire continents? The answer is a two-part travel team: rats and fleas!
Step 1: Starting in Asia
Scientists believe this terrifying plague actually started in China and Central Asia in the early 1300s. Changes in the climate might have made wild animals, like marmots, move closer to people, bringing the infected fleas with them.
Step 2: Jumping on the Trade Ships
These infected fleas loved to hang out on rats, especially the black rat. As people started trading more along giant routes like the Silk Road, the rats and their pesky, germ-carrying fleas hitched a ride on merchant ships!
The first big recorded arrival in Europe was in October 1347 when ships carrying the plague docked in Sicily, Italy. Once the rats and fleas arrived at the busy ports, they quickly spread the sickness to the people living nearby.
Step 3: Spreading from Person to Person
Once a person was bitten by an infected flea, they could get sick with the bubonic plague. However, there was another, even faster way it spread! If someone got the pneumonic plague (which attacked the lungs), they could cough and spread the germs through the air to others nearby. Cities were crowded, which meant germs could jump from person to person easily!
💡 Did You Know?
The word 'quarantine' actually comes from this scary time! Port cities like Ragusa (now Dubrovnik) made sailors wait on their ships for 40 days before coming ashore to make sure they weren't carrying the sickness!

What tiny creature was the main carrier that spread the plague from rats to people?
Who Were the Unlucky Victims?
The Black Death didn't care if you were rich or poor, royal or commoner—everyone was at risk!
Because medieval cities were often crowded and had poor cleaning (sanitation), they became perfect hiding spots for the rats and their fleas. Even monasteries, where monks lived very closely together caring for the sick, lost about half of their residents in some places!
- Bubonic Plague: The most common form, spread by flea bites. Victims got painful 'buboes.'
- Pneumonic Plague: Attacked the lungs and was spread by coughing, making it super contagious between people.
- Septicemic Plague: A rare and fast-acting form where the bacteria overwhelmed the bloodstream, often leading to death within a day.
Even though the main wave ended around 1351 or 1353, the plague didn't vanish forever! It kept coming back in smaller waves throughout the 14th and 15th centuries, reminding people that tiny germs can have a massive, history-changing impact!
