Peasants' Revolt

The Peasants' Revolt was a rebellion of peasants in England, in 1381. It was the biggest rebellion of farmers in medieval England.

Life of peasants.
There were two types of peasants: serfs and free peasants. 
Serfs were tenant farmers who worked without pay for a lord. In exchange, they got permission to live on the lord’s land. They also got protection from the knights living on the lord’s manor. Under feudalism, serfs had many difficulties. They barely had enough food to live on, and they had few possessions. They were not slaves, but they were not completely free. Serfs had less than any of the other social classes in medieval society.
Though they had more freedoms than serfs, life was also difficult for free peasants. Even though they were "free," they were still controlled by the higher social classes. They had to pay rent to live "free." They had to pay for many other things too, like collecting water or getting married.
Most peasants lived in houses which also housed the animals of the village.
