The English Peasants' Revolt of 1381 was a major uprising against the feudal system in England. It was sparked by high taxes, particularly the poll tax, and widespread discontent with the ruling class. Led by figures like Wat Tyler, the revolt saw thousands of peasants march to London, demanding social and economic reforms. The revolt gained significant momentum, with rebels capturing key locations and even entering the Tower of London. However, it was ultimately suppressed by the government forces. The aftermath led to harsh reprisals against the rebels, but it also highlighted the growing tensions between the peasantry and the nobility in medieval England.
