Beginning of the Peasants' Revolt in England.

The Peasants' Revolt, also named Wat Tyler's Rebellion or the Great Rising, was a major uprising across large parts of England in 1381. The revolt had various causes, including the socio-economic and political tensions generated by the Black Death in the 1340s, the high taxes resulting from the conflict with France during the Hundred Years' War, and instability within the local leadership of London. The revolt heavily influenced the course of the Hundred Years' War by deterring later Parliaments from raising additional taxes to pay for military campaigns in France.
