2. The Bubonic Plague
The Black Death

3. The Black Death
The Bubonic Plague killed 1/3 or 33% of the world’s population
It spread to everyone: From king to serf
It spread from Asia across Europe via trade routes
Transported by flea infested rats
Surviving serfs demanded higher wages from manors
Since they don’t get them, serfs move to cities looking for better economic opportunities
