Frequently Asked Questions

When did the Black Death happen?

The Black Death struck Europe mainly between 1347 and 1351 CE. It arrived after spreading west from Central Asia along busy trade routes. The disease returned in smaller waves for many years after that first deadly outbreak.

What percent of Europe’s population died in the Black Death?

Most historians agree that about half of Europe’s people died from the disease. In some crowded cities the losses were even higher. Large towns like Paris and London each lost roughly half of their residents.

Why did so many people die from the plague?

So many people died because medieval doctors did not understand how the disease spread. Poor hygiene let infected fleas and rats move freely through homes and towns. Without medicine or a cure, the plague passed quickly from person to person.

How was the Black Death spread?

The Black Death spread mostly through fleas that lived on rats and mice. These rodents traveled with merchants in caravans and aboard trading ships. Routes like the Silk Road carried the disease from Asia into the Middle East and Europe.

Did the Black Death affect places outside Europe?

Yes, the Black Death caused heavy losses across the Middle East and Asia too. When both regions are counted, the global death toll may have reached 200 million people. The disease first began in Central Asia before it ever reached Europe.
