While peasants had endured centuries of exploitation, the difficult conditions of the 14th to 15th centuries spurred a wave of peasant revolts across Europe.
The Jacquerie uprising happened in France in 1358 when French taxation for the Hundred Years' War fell heavily on the poor. Peasants blamed the nobility for oppressive taxes, committing terrible destruction throughout the countryside. It was eventually repressed by the upper class.
The English Peasants' Revolt in 1381 was ignited by the reimposition of a tax for the war. As the council announced the collection of the tax, it led to a major uprising. The assault was similar to that of the Jacquerie. It ended when Richard the 2nd crushed the revolt; consequently, it did not bring social equality to England.
